main roadmap installation official python packages onnx released packages are published in pypi sh pip install onnx or pip install onnx reference for optional reference implementation dependencies onnx weekly packages https pypi org project onnx weekly are published in pypi to enable experimentation and early testing vcpkg packages onnx is in the maintenance list of vcpkg https github com microsoft vcpkg you can easily use vcpkg to build and install it sh git clone https github com microsoft vcpkg git cd vcpkg bootstrap vcpkg bat for powershell bootstrap vcpkg sh for bash vcpkg install onnx conda packages a binary build of onnx is available from conda https conda io in conda forge https conda forge org sh conda install c conda forge onnx build onnx from source before building from source uninstall any existing versions of onnx pip uninstall onnx c 17 or higher c compiler version is required to build onnx from source on windows for other platforms please use c 14 or higher versions if you don t have protobuf installed onnx will internally download and build protobuf for onnx build or you can manually install protobuf c c libraries and tools https github com protocolbuffers protobuf with specified version before proceeding forward then depending on how you installed protobuf you need to set environment variable cmake args to donnx use protobuf shared libs on or donnx use protobuf shared libs off for example you may need to run the following command linux sh export cmake args donnx use protobuf shared libs on windows bat set cmake args donnx use protobuf shared libs on the on off depends on what kind of protobuf library you have shared libraries are files ending with dll so dylib static libraries are files ending with a lib this option depends on how you get your protobuf library and how it was built and it is default off you don t need to run the commands above if you d prefer to use a static protobuf library windows if you are building onnx from source it is recommended that you also build protobuf locally as a static library the version distributed with conda forge is a dll but onnx expects it to be a static library building protobuf locally also lets you control the version of protobuf the tested and recommended version is 3 21 12 the instructions in this readme assume you are using visual studio it is recommended that you run all the commands from a shell started from x64 native tools command prompt for vs 2019 and keep the build system generator for cmake e g cmake g visual studio 16 2019 consistent while building protobuf as well as onnx you can get protobuf by running the following commands bat git clone https github com protocolbuffers protobuf git cd protobuf git checkout v21 12 cd cmake cmake g visual studio 16 2019 a x64 dcmake install prefix protobuf install dir dprotobuf msvc static runtime off dprotobuf build shared libs off dprotobuf build tests off dprotobuf build examples off msbuild protobuf sln m p configuration release msbuild install vcxproj p configuration release then it will be built as a static library and installed to protobuf install dir please add the bin directory which contains protoc exe to your path bat set path protobuf install dir bin path please note if your protobuf install dir contains spaces do not add quotation marks around it alternative if you don t want to change your path you can set onnx protoc executable instead bat set cmake args donnx protoc executable full path to protoc exe then you can build onnx as git clone https github com onnx onnx git cd onnx git submodule update init recursive prefer lite proto set cmake args donnx use lite proto on pip install e linux first you need to install protobuf the minimum protobuf compiler protoc version required by onnx is 3 6 1 please note that old protoc versions might not work with cmake args donnx use lite proto on ubuntu 20 04 and newer users may choose to install protobuf via sh apt get install python3 pip python3 dev libprotobuf dev protobuf compiler in this case it is required to add donnx use protobuf shared libs on to cmake args in the onnx build step a more general way is to build and install it from source see the instructions below for more details details summary installing protobuf from source summary debian ubuntu sh git clone https github com protocolbuffers protobuf git cd protobuf git checkout v21 12 git submodule update init recursive mkdir build source cd build source cmake cmake dprotobuf build shared libs off dcmake

position independent code on is crucial by default static libraries are built without fpic flag they are not position independent code but shared libraries must be position independent code python c c extensions like onnx are shared libraries so if a static library was not built with fpic it can t be linked to such a shared library once build is successful update path to include protobuf paths

directory in this case you ll see modulenotfounderror no module named onnx onnx cpp2py export change into another directory to fix this error if you run into any issues while building protobuf as a static library please ensure that shared protobuf libraries like libprotobuf are not installed on your device or in the conda environment if these shared libraries exist either remove them to build protobuf from source as a static library or skip the protobuf build from source to use the shared version directly if you run into any issues while building onnx from source and your error message reads could not find pythonxx lib ensure that you have consistent python versions for common commands such as python and pip clean all existing build files and rebuild onnx again testing onnx uses

up the linux kernel will read the configuration from the onboard eeprom it will turn on the wifi driver now you can use wifi to connect to your wireless router or access point directly you will see the wifi driver wlan0 is up by typing the follow command using the command line ifconfig if you are in the command line you can add your wifi credentials to this file it will connect to the ap automatically edit the file sudo nano etc wpa supplicant wpa supplicant conf add network ssid your ap psk your pin key mgmt wpa psk reboot sudo reboot after associating to your router ap your rpi will broadcast mdns service so you do not need to know the ip address and the default host name is raspberrypi local you can use ssh to control your rpi from your computer remotely we only tested on macos and linux for windows you need a ssh utility and mdns tool e g apple bonjour sdk ssh pi raspberrypi local the default login password is raspberry trouble shooting if you do not see the wlan0 device using ifconfig then use the following command you should see there is a folder named iothat it should be something wrong if you do not see it ls proc device tree soc check if your board comes without the 40 pin connector soldered make sure your soldering is correct and check the i2c id eeprom pins see the pinout diagram for details bluetooth also upon booting up the board the kernel will read from the eeprom for all settings for the bluetooth including the uart which maps uart0 to gpio 14 and 15 you will see the bluetooth is ready to use by using the bluetooth manager the bluetooth icon near to

framework | accord net framework this project is currently archived please fork the project into your own github account if you would like to continue its development archiving after 14 15 years of development the accord net project has finally been archived i would like to send a big thank you to everyone who has ever comitted dedicated or otherwise devoted their time and effort into making this repository better every day what had started as a project to store knowledge in the form of algorithms and implementations had grown way beyond my expectations since i first joined university and started working on research 15 years ago in the meantime many things have happened and the ml landscape had also greatly evolved since then however i pledge you to absolutely not interpret the archiving of this project as a loss the main goal of this project since day 1 was to crystalize the ml knowledge available at the time in the form of source code and store it under a number of compatible free software licenses as such if you would like to do not feel afraid of copy and pasting portions of this project into your own implementations if i cesar de souza am the solely implementor of any of the classes you would like to port i hereby grant you an irrevocable license to do so if i am not and the current license of the file you would like to port does not suit your needs i can help you contact their original developers to help you with the transition pre we reject kings presidents and voting we believe in rough consensus and running code david clark pre all this

https gitter im accord net framework but to have issues and questions answered post it as an issue https github com accord net framework issues current status before you decide to use the framework for new projects please see the following personal note below i am writing this note to give an official status for the project this project has certainly been the most important thing i have ever created but i could not keep up with maintaining it as well as i wanted this project allowed me to achieve the biggest dream i had and that i never though i would have been able to achieve in my life which was some may laugh and possibly not understand specially if you did not know where i came from starting a new life and a new career here in europe for about 10 years i had worked on this project almost every day of my life but with the new life there came new steps to be climbed and i suddently had new responsabilities and things that i absolutely needed to accomplish very well i started a phd and had to focus on it so i could not keep up maintaining the library for about three years i tried to hire freelance developers to help maintain the project in the meantime i had to be absent and it worked to some extent but at some point i did not have the resources to keep up with the development anymore eventually i developed panic level anxiety since i felt i had left so many people behind by not being able to keep up with the development of the project anymore i found out that i would always avoid opening up the issues page of the project or even checking my own personal e mails just to avoid receiving new inquiries about the status of the project then a few months before my phd defense which happened very well actually microsoft announced that they wanted to make ml net which i actually fully support the standard approach for machine learning in net while this is great news because i fully support ms giving more support for all ml practitioners out there this eventually meant that accord net would eventually become obsolete as ml net was on its path to become the de facto ml library for net in the foreseeing future i think that the reasons above would have been already enough to explain why i decided to not update accord net anymore after that however in addition i have to say that as a researcher and not solely as a developer i have also published in and attended to the most important machine learning conferences in the world to date and under this context i need to say that in the academia world no one has ever heard of the framework or the project itself actually from my experience people in those conferences can laugh or even mistreat you if you ever mention you have ever developed anything in c specially for machine learning as everyone understandably uses python nowadays to accomplish tasks in this domain this happened even when those people were from microsoft itself i could actually understand the reaction as i myself only use python to do my day to day work and while i love c net i have to say that there is nothing that could even remotely compete with python pytorch at this day and age anyways therefore in the past months i have been pondering about archiving the project to avoid that i am willing to make someone who would like also an administrator of the project i am also willing to change the license of any file where i am the single author you can check the copyright headers in each file to mit so people can reuse individual pieces of code more easily anyone who becomes administrator is welcome to slice the parts of the project that still make sense to exist e g the ffmpeg wrappers statistical distributions statistical tests and the simple transforms like pca and even start new libraries hopefully in net core providing only them if wanted also when i started this project back in 2007 and when the original aforge library started even way before that there were almost no other libraries we could built upon so we had to do start almost everything from scratch this is not the case anymore any new libraries coming out of this project should definitely reuse existing libraries for basic tasks such as

https docs docker com desktop install linux install includes docker compose by default if this is your first installation of docker i would recommend just installing docker desktop docker desktop provides a nice gui that shows you all of your images running containers volumes etc so that you don t have to remember or worry about any docker cli commands configuring the project 1 fork this repository https github com subterfuge revived remake core fork 2 clone this repository git clone git github com subterfuge revived remake core git 3 add your fork as a remote cd remake core git remote add yourname url to your fork repository 5 using your ide open the subterfugeremake shared sln file this will open the project within your ide 6 to verify things worked run the unit tests expand the engine folder and right click on subterfugecoretest and click run unit tests or similar if your ide does not have the ability to do this the following command can be executed to run the tests instead dotnet test core subterfugecoretest 7 watch the tests pass note the subterfugerestapiservertest project requires both the database and the server to be running in order to pass please see the server readme server readme md for more information about the server repositories engine models https github com subterfuge revived remake core tree master core models the models project is a class library that contains c classes that are shared between the server and the client libraries this project mainly contains server client classes that are shared between one another and are generally used to produce network calls or are class objects that can be sereialized from the server s response these are mainly networking classes and should be pure classes with only fields and no methods subterfugecore https github com subterfuge revived remake core tree master core subterfugecore the bread and butter this project contains all of the game logic generating the game state loading a game from the server creating a new game launching a sub specialists combats outposts anything in game related is done here this library is used in unity to be able to determine what the current state of a game is and also used to load a gamestate from the network this project is also used on the server side to validate network requests verify submitted events and perform other validation checks for example if there is a winner of the game subterfugecoretest https github com subterfuge revived remake core tree master core subterfugecoretest unit tests for subterfuge core this project is purely for unit testing the main game logic unit tests ensure that upon future updates existing code and functionality is not broken when new changes get added to the game these unit tests get executed on every merge request and are required to pass before a merge request can be accepted ensure that any new code you write gets a unit test created for it server subterfugedatabaseprovider https github com subterfuge revived remake core tree master server subterfugedatabaseprovider a class library that creates database models for mongodb https www mongodb com and sets up all of the logic for mongodb around the database models the data here is all encapsulated by interface methods which make it easy to swap out our database provider with another database if we chose to in the future writing to and reading from the database is done here subterfugerestapiclient https github com subterfuge revived remake core tree master server subterfugerestapiclient a client repository for sending api requests to the server this client library is used to perform integration tests against the server but also used by the unity client to make interacting with the server easier subterfugerestapiserver https github com subterfuge revived remake core tree master server subterfugerestapiserver the subterfuge game server this project integrates database storage with incoming client api requests to facilitate multiplayer play the server stores and processes information like creating game lobbies joining game lobbies submitting game events adding friends sending chat messages and more subterfugerestapiservertest https github com subterfuge revived remake core tree master server subterfugerestapiservertest unit tesets for the subterfuge server this project performs integration tests against the subterfugeserver and requires a running database this project tests various server endpoints and validates that all of the required server functionality can be performed as expected using the core libraries the unity application makes use of the engine projects specifically subterfugecore which contains a class library with all of the primary game logic once the subterfugecore project is build a dll file is generated which needs to be included in the unity editor the unity repository has this file committed to ensure devs don t need to have both repos running however when working with the dll it is a good idea to view the api documentation on the class library here https subterfuge revived github io remake core index html to understand how to use classes that are avaliable for example how to load a game parse a gamestate from the server launch a sub alter the time machine etc | front_end |

llama2_aided_tesseract | use llama2 to improve the accuracy of tesseract ocr this project aims to improve the quality of optical character recognition ocr outputs using large language models llms purpose the purpose of the project is to convert scanned pdfs into readable text files it does this by first leveraging ocr and then enhancing the quality of the ocr output by using an llm to correct errors and format the text for readability example output if you just want to preview the output you can look at the source pdf https github com dicklesworthstone llama2 aided tesseract blob main

katharine graham letter raw ocr output txt and compare this to the final markdown output after filtering out hallucinations https github com dicklesworthstone llama2 aided tesseract blob main 160301289 warren buffett katharine graham letter filtered md and also compare to the initial output from the llm corrections https github com dicklesworthstone llama2 aided tesseract blob main

that you update the path in the model file path variable in the script appropriately how it works the project begins by converting a given pdf into images using the pdf2image library it then applies ocr to each image using pytesseract with parallel processing enabled via the multiprocessing library for speed the ocr ed text is subsequently passed through the llama2 13b chat model which aids in correcting ocr errors and enhancing the formatting of the text the program offers options to verify if the ocr output is valid english and to reformat the text using markdown the final text is written to an output file furthermore the project has a function to filter potential hallucinations from the llm corrected text using sentence embeddings and cosine similarity to compare with the original ocr text usage 1 set the input pdf file path variable to the path of the pdf file you want to process 2 set the max test pages variable to the number of pages you want to process if you set it to 0 the program will process all pages of the pdf file 3 set the skip first n pages variable to the number of pages you want to skip if you set it to 0 the program will process all pages 4 set the check if valid english variable to true if you want to check if the extracted text is valid english 5 set the reformat as markdown variable to true if you want to reformat the corrected extracted text using markdown formatting 6 run the program the program will create 3 output files 1 raw ocr output 2 llm corrected output 3 llm corrected output with hallucinations filtered out note this script is pretty slow particularly on longer pdfs the sample pdf mentioned above in the example output section took around an hour to completely process on a fairly powerful machine but where everything was done using a cpu rather than a gpu functions here are some of the important functions and what they do convert pdf to images func converts a pdf to images check extracted pages func checks if the extracted text is long enough to be a page remove intro removes the introduction from the llm output text is valid english checks if the given text is valid english process text with llm func processes the text with the llm calculate sentence embedding computes the sentence embedding for a given text calculate similarity computes the cosine similarity between the embeddings of the corrected and original sentences filter hallucinations filters out hallucinations from the corrected text ocr image performs ocr on the given image hallucination filtering the process of filtering out hallucinations is pretty intricate here is a detailed breakdown of how it works the primary function for this process is filter hallucinations which takes as arguments the text corrected by the llm corrected text the original text extracted by ocr raw text a starting threshold threshold for filtering the path to the pdf file pdf file path and the path to the sqlite database db path where embeddings are stored for reuse the function begins by defining a threshold increment of 0 02 this is the amount by which the threshold for filtering out hallucinations is incremented in each iteration if db path and pdf file path are provided the function first checks if an sqlite database file exists at the db path if it does not the function creates one it then computes a sha3 256 hash of the pdf file to uniquely identify it this hash is used as a key to store and retrieve embeddings from the database the function connects to the sqlite database and creates a table named embeddings if it does not already exist this table has three columns file hash original embeddings and corrected embeddings the function then tries to fetch the embeddings corresponding to the file hash from the database if it does not find them it sets original embeddings and corrected embeddings to none next the function creates a llamacppembeddings object which is used to compute embeddings for the sentences it then splits the raw text and corrected text into sentences if original embeddings is none the function calculates the embeddings for the original sentences and stores them in a dictionary where the keys are the sentences and the values are the embeddings it does the same for corrected embeddings once it has the embeddings the function saves them to the database using the pdf file s hash as the key the function then enters a loop where it filters out sentences from the corrected text based on the cosine similarity of their embeddings to the original sentences it starts with the initial threshold and in each iteration it increments the threshold by threshold increment in each iteration the function first initializes an empty list filtered sentences it then goes through each sentence in the corrected text for each sentence it gets its embedding from corrected embeddings and calculates its cosine similarity with the embeddings of the original sentences if the maximum similarity is greater than or equal to the current threshold the sentence is added to filtered sentences the function then joins the filtered sentences into a string filtered corrected text if the length of this text is less than the length of the original text minus 30 an arbitrary value to allow for some difference the function breaks the loop if not it increments the threshold and continues to the next iteration finally the function returns the filtered corrected text original embeddings and corrected embeddings there are two additional helper functions used in this process calculate sentence embedding this function takes as arguments a llamacppembeddings object and a text string it attempts to calculate the embedding of the text if it encounters an exception that the text has too many tokens it trims the text by 5 and tries again until it succeeds calculate similarity this function takes a tuple of two embeddings as argument and returns their cosine similarity this mechanism of filtering hallucinations is a heuristic approach and it might not be perfect the threshold and threshold increment values might need to be tuned according to the specific requirements of the use case contributions i made this mostly for fun and to learn more about using llms for more utilitarian tasks that being said i think this could eventually become a pretty useful tool for doing ocr on challenging files that result in tons of errors when using regular ocr without any smart corrections if you re interested in helping please submit a pr | ai-assist hallucinations llama2 llm ocr tesseract | ai |

sh install docker https docs docker com install optional not required for all commands but if you plan on building and deploying smart contracts you ll need docker installed more installation options more installation options quickstart if you just plan to read from the blockchain you do not need any go tokens and you do not need to set your web3 private key if you plan to deploy contracts or write anything to the blockchain you ll need tokens and you ll need to set your web3 private key for the account that has those tokens pick a network to use a run a local node run this command to start a local node it will print 10 addresses with keys upon starting that you can use to deploy and interact sh web3 start export web3 network localhost b use the gochain testnet sh export web3 network testnet to do any write operations you ll need some testnet go you can get some at https faucet gochain io or ask in gochain developers telegram group https t me gochain testnet c use the gochain mainnet or another web3 network sh export web3 network gochain you ll need mainnet go for this which you can buy on various exchanges https gochain io go d ethereum or any other web3 compatible network most people use infura for ethereum which requires an api key to use sign in to infura https infura io create a project click the settings tab and find your unique mainnet rpc url under endpoints then set web3 to use it with sh export web3 rpc url https mainnet infura io v3 youruniquekey set private key optional required if you plan to deploy or write transactions sh export web3 private key 0x deploy a contract copy contracts hello sol contracts hello sol into your current directory then sh web3 contract build hello sol web3 contract deploy hello bin you could also verify it in the block explorer after deployment sh web3 contract deploy verify hello flatten sol hello bin this will return a contract address copy it and use below read from a contract let s call a

hello and you ll get a json response like this json response hello world generating common contracts web3 includes some of the most common contracts so you can generate and deploy things like a token contract erc20 or a collectible contract erc721 in seconds the generated contract uses openzeppelin https openzeppelin org contracts so you can be sure these are secure and industry standard generate an erc20 contract sh web3 generate contract erc20 name test tokens symbol test that s it now you can literally just deploy it and be done or open the generated code to see what was generated and modify it to your liking to see all the available options for generating an erc20 contract use web3 generate contract erc20 help generate an erc721 contract sh web3 generate contract erc721 name kitties symbol cat to see all the available options for generating an erc721 contract use web3 generate contract erc721 help deploying an upgradeable contract the web3 tool comes with built in support for deploying contracts that can be upgraded later to deploy an upgradeable contract simply specify the upgradeable flag while deploying from our hello example above sh web3 contract deploy upgradeable hello bin this will return the contract address let s set the contract address environment variable so you can use it throughout the rest of this tutorial alternatively you can pass in the address contract address flag on all the commands sh export web3 address 0xcontract address internally deploying an upgradeable contract will actually deploy two separate contracts 1 your original hello contract 2 a proxy contract for redirecting calls and storage the returned contract address is the address of your proxy to see the contract address that your proxy is pointing to you can use the target command in the cli sh web3 contract target one caveat to using upgradeable contracts is that their constructors will not execute to get around this we will have to initialize our contract with an initial call to setname sh web3 contract call abi hello abi function setname world now we can interact with our upgradeable contract just like a normal contract sh web3 contract call abi hello abi function hello returns hello world alright so we have a working contract let s upgrade it upgrading the contract we can now deploy a different contract without the upgradeable flag and redirect our upgradeable contract to point to that new contract copy contracts goodbye sol contracts goodbye sol into your current directory and build and deploy it sh web3 contract build goodbye sol web3 contract deploy goodbye bin using the new goodbye contract address we can upgrade our previous contract using the contract upgrade command sh web3 contract upgrade to 0xgoodbye contract address we can see that our proxy contract now points to this new contract by calling the hello function again sh web3 contract call abi hello abi function hello returns goodbye world note that contracts can only be upgraded by the account that created them pausing and resuming a contract upgradeable contracts also include the ability to pause resume execution this can be useful if you discover a bug in your contract and you wish to cease operation until you can upgrade to a fixed version pausing a contract is simple sh web3 contract pause wait a minute for the transaction to go through then try to use the contract again and it will fail sh web3 contract call abi hello abi function hello returns error cannot call the contract abi unmarshalling empty output contracts can be upgraded while they are paused to execute any other contract functions you will need to first resume operation sh web3 contract resume the most common available commands global parameters choosing a network to choose a

dataset-cleaner | dataset cleaner notebook with instructions to clean your dataset in with interactive widgets in jupyter notebook this project consists of a dataset cleaner in jupyter notebook with the following functionalities image relabeler and deleter suggests mislabeled images and gives the user the option to relabel them by zach caceres http zachcaceres com now with help from jason patnick or directly delete them from the dataset let s see an example in cifar this doesn t look like a truck does it relabel delete away imgs not truck png image duplicate deleter suggests potential duplicates in the dataset and gives the user the option to delete them by francisco ingham let s see a few examples in cifar found a duplicate delete away imgs frog duplicate 2 png just be careful that the images you are deleting are actual duplicates and not augmented images like this one imgs frog duplicate 1 png how much difference can be considered a duplicate that s a good question and the decision is yours if one image is augmented many times and the other ones are not then the model will disproportionately weigh that image against the others and that is not what you want you don t want the model to favor one type of frog because it saw 5 images of it vs 1 image of the other types however augmentation generally is a good thing since it enriches the dataset and reduces overfitting conclusion if you can have augmentation without excessively augmenting one image over others then keep it otherwise you should delete some of the oversampled examples | ai |

configuration for most users json browserslist defaults if you want to change the default set of browsers we recommend including last 2 versions not dead 0 2 this is because last n versions on its own does not add popular old versions while only using a percentage of usage numbers above 0 2 will in the long run make popular browsers even more popular we might run into a monopoly and stagnation situation as we had with internet explorer 6 please use this setting with caution select browsers directly last 2 chrome versions only if you are making a web app for a kiosk with one browser there are a lot of browsers on the market if you are making general web app you should respect browsers diversity don t remove browsers just because you don t know them opera mini has 100 million users in africa and it is more popular in the global market than microsoft edge chinese qq browsers has more market share than firefox and desktop safari combined queries browserslist will use browsers and

not dead query composition an or combiner can use the keyword or as well as last 1 version or 1 is equal to last 1 version 1 and query combinations are also supported to perform an intersection of all the previous queries last 1 version or chrome 75 and 1 will select browser last version or chrome since 76 and more than 1 marketshare there are 3 different ways to combine queries as depicted below first you start with a single query and then we combine the queries to get our final list obviously you can not start with a not combiner since there is no left hand side query to combine it with the left hand is always resolved as and combiner even if or is used this is an api implementation specificity query combiner type illustration example or combiner br union union of queries img union svg 5 or last 2 versions br 5 last 2 versions and combiner br intersection intersection of queries img intersection svg 5 and last 2 versions not combiner br relative complement relative complement of queries img complement svg these three are equivalent to one another br 5 and not last 2 versions br 5 or not last 2 versions br 5 not last 2 versions a quick way to test your query is to do npx

esr not dead by usage statistics 5 browsers versions selected by global usage statistics and work too 5 in us uses usa usage statistics it accepts two letter country code 5 in alt as uses asia region

spree-on-react | spree on react code climate https codeclimate com github shubhamgupta spree on react badges gpa svg https codeclimate com github shubhamgupta spree on react rails is slow spree is slower the main purpose of this repository is to give a spree front end that is snappier and provides a more modern approach to solve the common problems found in e commerce space we are enthusiastic about this project and will continue supporting this project this project was bootstrapped with create react app https github com facebookincubator create react app you can tweak any build related configuration by following this package introduction spree on react provides a complete front end for spree https github com spree spree built entirely on reactjs https facebook github io react it works with spree ams https github com vinsol spree ams gem which is written using activemodelserializers and is a faster and a better alternative to the core spree api the purpose of this repository is to continue to evolve spree making it faster and easier to use stack 1 reactjs 2 reactbootstrap 3 redux and related packages 4 react router 5 webpack for deployment for a comprehensive list see package json features implemented 1 user login logout 2 product listing with infinite scroller 4 product filtering by taxons 5 product search 6 cart logged in as well as guest users 7 checkout steps logged in as well as guest users 8 order listing for logged in users 9 route handling 10 using local storage to maintain orders and session information in browser 11 i18n adapters this project depends on the spree ams gem as mentioned above this response is not particularly suited for traversing adapter classes process the response sent by spree ams to make it more traversable across the application we use this processed response while dispatching redux actions example raw response json product id 1 product property ids 1 2 3 product properties id 1 name brand value reebok id 2 name color value red processed response nesting properties inside products json product id 1 product property ids 1 2 3 product properties id 1 name brand value reebok id 2 name color value red our long term goal is to evntually get rid of these adapter classes and use redux orm as it is more scalable however the library is yet to release its first stable version setup this application is under initial development currently it uses a spree api server as its data source to run the fe to set up the project clone this repository sh git clone https github com vinsol spree contrib spree on react cd spree on react install node and npm there are already a lot of resources on how to install node and npm for your operating system install node and npm and come back to follow this project is tested on node version 5 3 0 and higher install project dependencies this will install everything you ll need to run this application sh npm install setup the environment file the application depends on a few environment variables create a env file at the root directory of your project and add the following variables change the values based on your backend sh touch env vi env list of configuration variables react app api base http localhost 3001 api v1 react app ams api base http localhost 3001 api ams react app api host http localhost 3001 react app allow guest signup false react app spree api token 2342862741qweqw7te27632 note we are using spree s core api for fetching countries and states as ams is not really efficient for these end points so we need api base for both core and ams imp note by default spree requires an api token for user signup react app allow guest signup is therefore set to false by default if this api token is disabled under spree make sure to set this env variable to true to ignore this token on signup actions if react app allow guest signup is false then react app spree api token is required build the languages 1 export the node env sh echo export node env development bash profile ubuntu desktop note modify your bashrc instead of bash profile zsh note modify your zshrc file instead of bash profile 2 generate the locale files sh npm run build langs note npm run build generates the locale files as well as the final build this should be used for generating the production build run the fe server this runs a local server on http localhost 3000 sh npm start start your spree project server finally run your spree project on port 3001 or whatever port you specified in env file this will serve as the api to run the frontend add spree ams to your gemfile sh cd path to your rails spree project ruby gem spree ams github vinsol spree contrib spree ams branch 3 1 stable run your rails server sh bundle exec rails server p 3001 open http localhost 3000 adding new languages the project uses react intl https github com yahoo react intl for localization the locale files are written in json format the keys are flat in heirarchy no nested keys lets consider that we are adding locales for french 1 create a directory inside the locales directory with name fr 2 copy the keys from an existing locale file from locales directory in to the fr directory created above 3 add actual language translations as values to the keys 4 translate the locales below is the task defined in package json to build the locales the same has also been coupled with npm run build to assist in production deployment sh npm run build langs this task should serve most common needs for more complex requirements you can easily tweak this task according to your needs see scripts translate js demo https spree on react herokuapp com example credentials email spree on react example com password spree vinsol read more see this blog post http vinsol com blog 2017 07 11 spreeonreact a spreecommerce storefront built on reactjs whats remaining 1 implement webpack s code splitting for smaller bundle sizes 2 deployment on aws using nginx upcoming features we are heavily working on the below features our constant focus is on to improve the code quality making the separation of concerns between components and container more pronounced 1 adding type checking with flow where are the test cases this repository is still very young and adding new features is our top priority we ll begin writing test cases once we have build most of the spree core functionality

ensure you have the following prerequisites git https git scm com docker https docs docker com get docker docker compose https docs docker com compose install reproducing the app to reproduce this project follow these steps 1 clone the repository bash git clone https github com lucca miorelli premier league data engineering git cd premier league data engineering 2 install docker and docker compose if you haven t already install docker and docker compose using the official installation guides docker installation https docs docker com get docker docker compose installation https docs docker com compose install 3 run the application in the project root directory run the following command to build and start the containers bash docker compose up build 4 stop the application to stop the containers and remove them use the following command bash docker compose down v the desired outcome is that the python container runs app py and performs etl on premier league data pushing it to a postgresql database in the other container by the end it runs 4 sql files from the sql folder and stores the results in csv files in a local folder mounted to the container named data env example here s an example of the env file you should create to reproduce the environment variables needed plaintext env database configuration postgres db you db name postgres user your username postgres password your password api keys api key your api key this will be used to set the environment variables in the docker compose yml file normalization choices normalization choices i have made specific normalization choices for the database design based on the structure and relationships of our data however it s essential to acknowledge that due to time limitations i had to prioritize the completion of the full assignment over achieving ideal data quality and data integrity i recognize that data integrity and quality are paramount in any data engineering project and they must always be at the forefront of my considerations in this particular case achieving a highly normalized database structure would have been time consuming and might have delayed the deployment of the full application as a consequence of this trade off some of my sql queries might not be as performant as i would have liked nevertheless i maintained a balance between meeting the assignment requirements and the need to deploy the complete application on time i understand that there is room for improvement in optimizing the database schema and queries for better performance while ensuring data integrity and quality database tables assets premierleaguedb png we have tables for teams goalscorers cards substitutions lineups players statistics match details and match scores each table serves a specific purpose and primary and foreign keys are used to establish relationships where necessary challenge guidelines 1 api access and key retrieval x registered an account on the apifootball site x secured the api key x utilized league id 152 premier league x made two separate requests utilizing specified date ranges due to api limits 2 database design x created a compact dimensional model for events data comprising dimensions and facts 3 sql queries x final league table query outputs position team name matches played won draw lost goals scored goals conceded and points with proper points allocation and tiebreakers x display all teams sorted by away goals scored x top 5 referees with most cards query x top 3 goal scorers by match round 14 query 4 data export x exported query results to csv files query a csv query b csv query c csv and query d csv 5 docker container and app deployment x developed a docker container to host the application 6 readme file x created a comprehensive readme file detailing assumptions choices and instructions to execute the application 7 github repository x uploaded the project to a github repository contact thanks for exploring the premier league data

creating a sufia based app and contributing new features to sufia after installing the prerequisites if you would like to create a new application using sufia follow the instructions for creating a sufia based app creating a sufia based app if you would like to create new features for sufia follow the instructions for contributing contributing and development development prerequisites sufia 7 requires the following software to work 1 solr http lucene apache org solr version 5 x tested up to 6 4 1 1 fedora commons http www fedora commons org digital repository version 4 5 1 tested up to 4 7 1 1 a sql rdbms mysql postgresql though note that sqlite will be used by default if you re looking to get up and running quickly 1 redis http redis io a key value store 1 imagemagick http www imagemagick org with jpeg 2000 support 1 fits characterization version 0 8 x 0 8 5 is known to be good 1 libreoffice derivatives note the sufia development guide https github com samvera sufia wiki sufia development guide has instructions for installing solr and fedora in a development environment characterization 1 go to http projects iq harvard edu fits downloads and download a copy of fits see above to pick a known working version unpack it somewhere on your machine 1 mark fits sh as executable chmod a x fits sh 1 run fits sh h from the command line and see a help message to ensure fits is properly installed 1 give your sufia app access to fits by 1 adding the full fits sh path to your path e g in your bash profile or 1 changing config initializers sufia rb to point to your fits location config fits path your full path fits sh derivatives install libreoffice https www libreoffice org if which soffice returns a path you re done otherwise add the full path to soffice to your path in your bash profile for instance on osx soffice is inside libreoffice app your path may look like your full path to libreoffice app contents macos you may also require ghostscript http www ghostscript com if it does not come with your compiled version libreoffice brew install ghostscript should resolve the dependency on a mac note derivatives are served from the filesystem in sufia 7 which is a difference from earlier versions of sufia environments note here that the following commands assume you re setting up sufia in a development environment using the rails built in development environment if you re setting up a production or production like environment you may wish to tell rails that by prepending rails env production to the commands that follow e g rails rake bundle and so on ruby first you ll need a working ruby installation you can install this via your operating system s package manager you are likely to get farther with osx linux or unix than windows but your mileage may vary but we recommend using a ruby version manager such as rvm https rvm io or rbenv https github com sstephenson rbenv we recommend either ruby 2 3 or the latest 2 2 version redis redis http redis io is a key value store that sufia uses to provide activity streams on repository objects and users and to prevent race conditions as a global mutex when modifying order persisting objects starting up redis will depend on your operating system and may in fact already be started on your system you may want to consult the redis documentation http redis io documentation for help doing this rails we recommend the latest rails 5 0 release if you don t already have rails at your disposal gem install rails v 5 0 1 creating a sufia based app generate a new rails application using the template rails new my app m https raw githubusercontent com samvera sufia master template rb generating a new rails application using sufia s template above takes cares of a number of steps for you including adding sufia and any of its dependencies to your application gemfile to declare that sufia is a dependency of your application running bundle install to install sufia and its dependencies running sufia s install generator to add a number of files that sufia requires within your rails app including e g database migrations loading all of sufia s database migrations into your application s database loading sufia s default workflows into your application s database generate a work type while earlier versions of sufia came with a pre defined object model sufia 7 allows you to generate an arbitrary number of work types let s start by generating one pass a camelcased model name to sufia s work generator to get started e g rails generate sufia work work or rails generate sufia work movingimage start servers to test drive your new sufia application in development mode spin up the servers that sufia needs solr fedora and rails rake hydra server and now you should be able to browse to localhost 3000 http localhost 3000 and see the application note that this web server is purely for development purposes you will want to use a more fully featured web server https github com samvera sufia wiki sufia management guide web server for production like environments add default admin set after fedora and solr are running create the default administrative set by running the following rake task rake sufia default admin set create you will want to run this command the first time this code is deployed to a new environment as well note it depends on loading workflows which is run by the install template but also needs to be run in a new environment rake curation concerns workflow load managing a sufia based app the sufia management guide https github com samvera sufia

extend the lab 2 hardware design by creating and adding an axi peripheral to the system and connecting it to the leds on the zynq board you are using you will use the ip packager to generate the custom ip next you will connect the peripheral to the system and add pin location constraints to connect the led display controller peripheral to the on board led display finally you will add bram controller and bram before generating the bitstream p align center img src pics readme l3view jpg width 80 height 80 p p align center i design updated from the previous lab i p lab 4 this lab guides you through the process of writing a basic software application the software you will develop will write to the leds on the zynq board an axi bram controller and associated 8kb bram were added in the last lab the application will be run from the bram by modifying the linker script for the project to place the text section of the application in the bram you will verify that the design operates as expected by testing in hardware the design was extended at the end of the previous lab to include a memory controller and the bitstream should now be available a basic software application will be developed to access the leds on the zynq boards lab 5 this lab guides you through the process of writing a software application that utilizes the private timer of the cpu you will refer to the timer s api in the sdk to create and debug the software application the application you will develop will monitor the dip switch values and increment a count on the leds the application will exit when the center push button is pressed you will use the hardware design created in lab 4 to use cpu s private timer see figure you will develop the code to use it p align center img src pics readme l5view jpg

snooze | build status https travis ci org joaotavora snooze svg branch master https travis ci org joaotavora snooze snooze snooze is an url router for common lisp designed around rest web services rest an url router lets you open url routes to your application that are friendlier easier to remember and better supported by other applications such as search engines restful routes are near universal in web apis and look like this restful routes all snooze does is establish a tight fit between this type of route and plain old common lisp for example in snooze routes are just functions and http conditions are just lisp conditions since you stay inside lisp if you know how to make a function you know how to make a route there are no regular expressions to write or extra route defining syntax to learn snooze is web server backend agnostic it can work with any web server other backends here s an example you can try out quickly a micro rest service to read and write lisp docstrings over http lisp defpackage readme demo use cl snooze in package readme demo defun find symbol or lose name package or find symbol string name find package package http condition 404 sorry no such symbol defroute lispdoc get text name key package cl doctype function or documentation find symbol or lose name package doctype http condition 404 sorry a doesn t have any a doc name doctype defroute lispdoc post text plain name key package cl doctype function setf documentation find symbol or lose name package doctype payload as string let s use clack as a server backend clack clackup snooze make clack app port 9003 this establishes two routes get for reading and post for writing on the uri localhost 9003 lispdoc symbol here s an illustration of how they respond http get lispdoc defun 200 ok get lispdoc funny syntax package snooze 404 not found get lispdoc in valid args 400 bad request get lispdoc defun 406 not acceptable accept application json post lispdoc scan package cl ppcre 200 ok content type text plain post lispdoc defun 415 unsupported media type content type application json the error codes 400 406 and 415 are error reporting that you get for free if the http client strays off these routes be it for improper syntax or unsupported content types the correct http condition is signalled the rest of this readme contains the rationale rationale for building snooze and a tutorial tutorial that builds on the simple application presented above status ah snooze is kinda beta the usual disclaimer of warranty applies rationale there are already some common lisp systems for http routing like caveman caveman cl rest server cl rest server restas restas and ningle ningle unfortunately they tend to make you learn some extra route defining syntax on the contrary snooze maps rest http https en wikipedia org wiki rest concepts to common lisp concepts http rest concept snooze cl concept rest resource clos generic function route clos method verbs get post delete etc clos specializer on first argument accept and content type clos specializer on second argument uri path path1 path2 path3 required and optional arguments url queries param value p2 v2 keyword arguments status codes 404 500 etc cl conditions this has many advantages for example since every route is a method you can trace it like a regular function find its definition with m or even use around qualifiers using a regular lambda list guarantees that uri errors can be spotted early by your compiler there is no need to write code to extract arguments from the uri since snooze knows the lambda list of a route it can use it to do the reverse of uri matching generate uris that perfectly match that same route tutorial consider the code sample presented above snooze let s pick up where we left off and build a bit more of lispdoc our docstring manipulating application we ll see how to understand snooze s rest resources resources as generic functions dispatch on http methods and content types content types generate and encode compatible uris uri generation grafully handle failure conditions controlling errors control conversion of uri arguments how snooze converts uri components to arguments refactor routes without changing the api tighter routes hook snooze into the backend of your choice other backends this tutorial assumes you re using a recent version of quicklisp quicklisp so start by entering this into your repl lisp push path to snoozes parent dir quicklisp local project directories ql quickload snooze make sure you keep an eye on the docstrings of the functions mentioned they are where the real api reference lives find them all appropriately in the api lisp https github com joaotavora snooze blob master api lisp file resources as generic functions an important detail that was elided from the initial sample is that in snooze a rest resource is implemented a clos generic function the operations get post delete etc accepted by a resource are implemented as clos methods on that generic function when a http request is received snooze arranges for its uri to be translated into a generic function name and its remaining properties verb content type additional uri bits to be translated into arguments for that function snooze then calls that function with those arguments and clos does the rest if one of the methods of this generic function matches its body is called and the http client sees a nice response otherwise a condition is signalled and snooze takes care that the http client sees the correct error code under the hood defroute is actually a really thin wrapper on defmethod you can even use defmethod directly if you prefer lisp defmethod lispdoc snooze verbs http verb snooze verbs post snooze types type snooze types text plain name key package cl doctype function setf documentation find symbol or lose name package doctype payload as string likewise there is a defresource form that is equivalent to defgeneric it may be left out since it is implicit in the first defroute call this means we could have defined the above application in an equivalent terser form lisp defresource lispdoc verb content type name key route get text name key package cl doctype function or documentation find symbol or lose name package doctype http condition 404 sorry a doesn t have any a doc name doctype route post text plain name key package cl doctype function setf documentation find symbol or lose name package doctype payload as string content types let s start by serving docstrings in html as seen above we already have a route which serves plain text lisp defroute lispdoc get text name key package cl type function or documentation find symbol or lose name package type http condition 404 sorry no a doc for a type name to add a similar route for the content type text html we just notice that text html is text also because routes are really only clos methods the easiest way is lisp defroute lispdoc around get text html name key allow other keys format nil h1 docstring for a h1 p a p name call next method this will do fine for now of course later we should probably escape the html with something like cl who cl who s escape string all we might also consider removing the around qualifier and use a helper function shared by two routes let s try our hand at implementing an important part of the api post requests with json content lisp defroute lispdoc post application json name key package cl doctype function let json handler case you ll need to quickload cl json json decode json from string payload as string error e http condition 400 malformed json a e sym find symbol or lose name package docstring cdr assoc docstring json if and sym docstring doctype setf documentation sym doctype docstring http condition 400 json missing some properties uri generation our application has a growing number of routes that work fine provided the use knows how to type them because this is increasingly complicated as more and more routes are added it is very often the case that we ll want parts of the our rest application to generate uri s that match its own routes probably the most common case is providing a link to a specific resource in an html response this is very easy to do in snooze as it can automatically generate the uris for a resource you first need to get a genpath function for your resource just do lisp defgenpath lispdoc lispdoc path or alternatively pass genpath to defresource defresource lispdoc verb ct symbol genpath lispdoc path the newly generated lispdoc path has an argument list that perfectly matches your route s arguments lisp lispdoc path defroute package snooze lispdoc defroute package snooze lispdoc path defun lispdoc defun lispdoc path standard output doctype variable lispdoc 2astandard output 2a doctype variable lispdoc path standard output foo hey error unknown key argument foo notice the automatic uri encoding of the character and how the function errors on invalid keyword arguments that would produce an invalid route path generators are useful for example when write html links to your resources in our example let s use it to guide the user to the correct url when an easily fixed 404 happens lisp defun doc not found message name package doctype let othertype if eq doctype function variable function otherdoc documentation find symbol or lose name package othertype with output to string s format s there is no a doc for a doctype name when otherdoc format s p but try a href a here a p lispdoc path name package package doctype othertype defroute lispdoc get text html name key package cl doctype function or documentation find symbol or lose name package doctype http condition 404 doc not found message name package doctype if you now point your browser to http localhost 9003 lispdoc 2astandard output 2a doctype variable you should see a nicer 404 error message except you don t because by default snooze is very terse with error messages and we haven t told it not to be so don t worry the next sections explains how to change that controlling errors errors and unexpected situations are part of normal http life many websites and rest services not only return an http status code but also serve information about the conditions that lead to an error be it in a pretty html error page or a json object describing the problem snooze tries to make it possible to precisely control what information gets sent to the client it uses a generic function and two variables explain condition condition resource content type catch errors catch http conditions out of the box there are no methods on explain condition and the two variables are set to t this means that any http condition or a lisp error in your application will generate a very terse reply in plain text containing only the status code and the standard reason phrase you can amend this selectively by adding explain condition methods that explain http conditions politely in say html lisp defmethod explain condition condition http condition resource eql lispdoc ct snooze types text html with output to string s format s h1 terribly sorry h1 p you might have made a mistake i m afraid p format s p a p condition the above explains only http conditions that are the client s fault but you can use the same technique to explain any error like so lisp defmethod explain condition error error resource eql lispdoc ct snooze types text html with output to string s format s h1 oh dear h1 p it seems i ve messed up somehow p finally you can play around with catch errors and catch http conditions see their docstrings i normally leave catch http conditions set to t and catch errors set to either verbose or nil depending on whether i want to do debugging in the browser or in emacs how snooze converts uri components to arguments you might have noticed already that the arguments passed to the clos generic functions that represent resources are actual lisp symbols extracted from the uri whereas other frameworks normally pass them as strings what are the advantages of this let s drift from the lispdoc example a bit consider this fragment of a beatle listing app lisp defclass beatle id initarg id name initarg name accessor name guitars initarg guitars accessor number of guitars defparameter beatles list make instance beatle id 1 name john guitars 1 make instance beatle id 2 name paul guitars 2 make instance beatle id 3 name ringo guitars 0 make instance beatle id 4 name george guitars 10 defroute beatles get text plain key key number of guitars predicate assert safe functions key predicate format nil a mapcar name sort copy list beatles predicate key key defgenpath beatles beatles path the defgenpath form makes beatles path be a function of two keyword arguments key and predicate that returns the perfect uri for accessing the beatles route among other things you can name regular functions like and string lessp in this example by their symbols as you would in pure lisp lisp cl user beatles path key number of guitars predicate beatles key number of guitars predicate 3c cl user beatles path key name predicate string lessp beatles key name predicate string lessp sure enough feeding these uris to the http client causes the function beatles to be called with exactly the same symbols that you passed to beatles path now if you re thinking that this doesn t fit needs know that it is merely a default behaviour and entirely configurable if you really want to have the uri path foo bar baz become the strings foo bar and baz in your application you merely need to add a clos method to the each of the generic functions read for resource and write for resource nevertheless i recommend you keep the default the default read for resource uses a very locked down version of cl read to string that doesn t intern symbols for security allow any kind of reader macros or read anything more complicated than a number a string or a symbol the default write for resource does the inverse it writes onto a string of any object so that read for resource can reconstruct that object from the string so long as the object is a secure thing to serialize over uri there is perhaps a better way to influence the mapping between uris and arguments to that effect two other functions are discussed in the next section arguments to uri and uri to arguments tighter routes let s recall the lispdoc app the routes we have until now are functions of a string to convert them into actual symbols they need the find symbol or lose helper an additional package keyword arg this isn t pretty it would be nicer if routes were functions of a symbol after all in common lisp passing symbols around shouldn t force you to pass their packages separately so basically we want to write our methods like this lisp defroute lispdoc get text sym symbol key doctype function or documentation sym doctype http condition 404 doc not found message sym doctype actually this will work just fine out of the box oh wait now our routes look like this lisp lispdoc path cl ppcre scan lispdoc cl ppcre 3ascan lispdoc path ql quickload lispdoc quicklisp client 3aquickload compare these to the routes at the very top of this document lisp lispdoc scan package cl ppcre lispdoc quickload package ql you might be dissapointed that the new ones are not as human readable the 3a encoding for the looks would look slightly bizarre to a user reading it in the browser s address bar but even if you don t care about appearance and find them perfectly acceptable it is conceivable that we had already published the routes of the older rest api to the world so to keep that api we need to change the implementation without changing the interface this is where uri to arguments and its reciprocal arguments to uri come in handy these generic functions have default implementations for all resources that can be leveraged for surgical tweaks like the one we need here uri to arguments receives an uri string and make it compute a values list of plain and keyword arguments that are passed to the route after the verb and content type in our case we first parse the plain symbol name and package using call next method then compute an actual symbol we also make sure to not pass package to our new route as it doesn t accept it arguments to uri is the function that allows the genpath function to produce matching uris it does the reverse producing an uri string in this case it takes a symbol in plain args after extracting its package and massaging it into an uninterned symbol we also use call next method to simplify things lisp defmethod uri to arguments resource eql lispdoc uri multiple value bind plain args keyword args call next method let sym name string first plain args package name or cdr assoc package keyword args cl sym find symbol sym name package name unless sym http condition 404 sorry no such symbol values cons sym cdr plain args remove package keyword args key car defmethod arguments to uri resource eql lispdoc plain args keyword args let sym first plain args call next method resource list sym cons package make symbol package name symbol package sym keyword args we can now safely rewrite the remaining routes in much simpler fashion here s the rest of the application now notice also how doc not found message was also simplified lisp defun doc not found message symbol doctype let othertype if eq doctype function variable function otherdoc documentation symbol othertype with output to string s format s there is no a doc for a doctype symbol when otherdoc format s p but try a href a here a p lispdoc path symbol doctype othertype defroute lispdoc get text sym symbol key doctype function or documentation sym doctype http condition 404 no doc found for a sym defroute lispdoc post text plain sym symbol key doctype function setf documentation sym doctype payload as string defroute lispdoc get text html sym symbol key doctype function or documentation sym doctype http condition 404 doc not found message sym doctype defroute lispdoc post application json sym symbol key doctype function let json handler

visual regression testing check backstop https github com garris backstopjs for general configuration questions our visual regressions audits can be performed against all patterns documented within the project s component proving grounds to do so follow the steps below 1 run the project locally with npm run dev 2 npm run reference will create a base set of images providing coverage for all defined patterns ensure this is run against a clean build prior to any edits 3 npm run compare after making changes to the markup or css this will create another set of test images and compare them against those generated in the previous step 4 review the generated report that should open in your browser make sure all changes are what you expect 5 npm run approve if everything looks good this will promote the latest test images to be the new reference images that future tests will be compared against if you want to do backstop tests against a single scenario you can do npm run compare filter label the config backstop js looks through src for all backstop js and generates a proper backstop scenario object for each backstop js files will export an array of objects that are standard backstop scenario objects and support all the same options noted in the docs with the following exceptions responsive boolean configures whether or not the scenario runs against all 4 breakpoints if not present or false it will only run against the largest breakpoint note that running responsive tests against specific selectors can often lead to incorrect screenshots and it is better to set up a

creating a pull request run git cz rather than git commit and follow the prompts jsx cedar templates are written in jsx rather than as vue sfcs in order to support tree shaking see jsx notes jsx md for more information creating new components you can generate new cedar components by running node generator js the new component will be compiled based on the template inside templates after running the generator it will list out some manual steps that must be taken in order to add that new component to the main entry point and make it available in the dev environment dist structure this project uses rollup to compile the cedar components into cjs and esm format the module paramater in the package json defines a tree shakeable esm entry point which is what should be used by consumers of cedar for their production build the single file cedar js and cedar mjs outputs are available for ease of setting up test dev internal projects but should not be used for customer facing production sites as those files are not tree shakeable and they contain all of the code in cedar dist lib contains individual files matching the directory structure of cedar this is generated using the preservemodules option in rollup and is necessary for the cedar distributable to be tree shakeable src index js main entry point for esm cedar tree shake able style contains individual css files for each cedar

transfer-learning-keras | transfer learning experiments with keras this repository contains several explorations pertaining to transfer learning also sometimes referred to as domain adaptation using imagenet as a source dataset and caltech 101 http www vision caltech edu image datasets caltech101 as a target dataset it is able to achieve 90 79 test accuracy on caltech 101 in just 129 seconds of cpu training on a standard macbook air quick start 1 follow instructions to install keras https github com fchollet keras 2 install h5py http www h5py org to cache and load models 3 download caltech 101 http www vision caltech edu image datasets caltech101 and place under the data caltech 101 directory 4 python generate cnn codes py to generate the cnn codes time intensive step 5 python train model py to train the transfer learned model helpful resources here are some resources i found helpful for these experiments http ruder io transfer learning index html fn 13 http ruder io transfer learning index html fn 13 http cs231n github io transfer learning http cs231n github io transfer learning keras documentation on applications https keras io applications cnn features off the shelf an astounding baseline for recognition https arxiv org pdf 1403 6382 pdf visualizing and understanding convolutional networks https arxiv org pdf 1311 2901v3 pdf model this repository trains a softmax multi class classification model that takes as input the final convolutional layer of a model pre trained on imagenet and outputs a set of class probabilities although transfer learning experiments often involve the fine tuning of all layer weights these experiments only train a single layer of weights to ensure the possibility of training in a low resource environment in fact the most computationally intensive portion is computing the forward pass cnn codes on each training example takes a few hours on a laptop whereas the training can achieve a reasonable accuracy in a matter of minutes one gotcha for that may have polluted some of these experimental results is that caltech 101 contains a small amount of overlap of 44 images with imagenet out of 9 144 total images as noted in this paper https arxiv org pdf 1311 2901v3 pdf because i didn t have the resources to retrain an imagenet model without this overlap i have ignored this pollution for now experiments the performance numbers from the following experiments are taken from experiments on my macbook air with a 2 2 ghz intel core i7 and 8 gb of ddr3 ram i split each class in the caltech 101 dataset into 70 training and 30 test to run these experiments some baseline accuracies for caltech 101 are avaiable at this link http zybler blogspot com 2009 08 table of results for famous public html to compare the following results against these used a slightly different training and experiment setup than i did so should be used only to provide rough context and not as an aboslute comparison inception v3 https arxiv org pdf 1512 00567 pdf the final convolutional layer of the inception v3 model has an output shape of 5 x 5 x 2048 resulting in a flattened cnn code of 51 200 dimensions since this is a quite large softmax layer training on my laptop in a short amount of time was more intensive than vgg19 however i was able to reach a performance of 90 79 test accuracy in just 5 epochs of training 129 seconds quite remarkable for such a small amount of epochs training data vgg19 https arxiv org pdf 1409 1556 pdf the final convolutional layer of vgg19 has an output shape of 7 x 7 x 512 or 25 008 flattened this model converged more slowly than inception but i was able to train it for more epochs due to the smaller size i got a performance of 79 08 test accuracy after 25 epochs of training 328 seconds number of training instances one interesting application of transfer learning in addition to it s efficiency is the surprising effectiveness in a low data setting to visualize this i have conducted experiments where i have limited the maximum number of training instances per class to various levels and charted the resulting model test accuracy chart png it s quite incredible to note the generalization of these models with such little training data on the inception model it is almost a little difficult to believe perhaps the pollution of the imagenet dataset is coming into play here todo yoavz some interesting directions to experiment with if i ever find the time 1 learn on a different target dataset such as a hand collected facial recognition dataset these experiments indicate that i may not need that many training instances for effective performance 2 remove pollution from imagenet models to achieve true precision results 3 train models with fine tuning | ai |

snooty | mongodb documentation front end uses gatsby https www gatsbyjs org to build static site installation snooty uses artifactory https jfrog com artifactory that will need authentication https github com mongodb snooty blob master npmrc to install some private npm packages update your local zsh variables in zshrc in windows userprofile zshrc to include the following export npm base 64 auth base 64 api key export npm email your email gmail com then to install the package dependencies shell npm install legacy peer deps env file setup you ll need to set some environment variables in two separate files at the root of this directory for separate production development environments these variables let snooty know where to look for your ast zip files within dop team s database you can also use local ast files running with local manifest path env development snooty s develop stage uses the development environment your env development file should be as follows gatsby site site gatsby parser user user gatsby parser branch branch gatsby snooty dev true the gatsby snooty dev variable is what allows gatsby to know that it should use the snooty branch name as part of the file paths when not set the file paths will use the value of gatsby parser branch see pathing here https github com mongodb snooty blob master src utils generate path prefix js l22 it should be set to true when working on snooty locally env production snooty s build and serve stages use the production environment your env production file should be as follows gatsby site site gatsby parser user user gatsby parser branch branch gatsby snooty dev true running locally shell npm run develop to build and serve the site run the following commands the serve command generates the site at a prefix https github com mongodb snooty blob master src utils generate path prefix js ie localhost 9000 branch docs name user branch name shell npm run build npm run serve to debug server side shell node nolazy node modules bin gatsby develop inspect brk and connect a node debugger ie chrome developer tools https nodejs org en docs guides debugging getting started inspector clients running with local manifest path alternative to working with remote ast files you can have a local zip file to build the site this removes the need for previously mentioned env variables required for remote lookup gatsby site gatsby parser user and gatsby parser branch local zip file is an output of the parser https github com mongodb snooty parser env development and env production gatsby manifest path path to zipped ast file zip gatsby snooty dev true running with gatsby cloud preview snooty uses gatsby cloud to perform content staging builds for mongodb documentation these builds source their asts through the snooty data api https github com mongodb snooty data api and require additional environment variables for setup to emulate a gatsby cloud preview build locally include the following in your env development file gatsby cloud site user your github username since building with the gatsby cloud preview source plugin expects build data to be present in our team s database please use the autobuilder to perform one or more builds prior to running the frontend otherwise use a different gatsby cloud site user when ready run the following command shell npm run develop preview this command will run the gatsby source snooty preview source plugin where all ast data for the specified gatsby cloud site user will be used to mimic a gatsby cloud site locally all build data across every unique project branch combination for that user will be built on the single site to access the built content go to http localhost 8000 project branch page path note that this process assumes that the default public snooty data api endpoint is being used if the staging instance of the api is desired you will need to set the api base env to the staging url include the expected client credentials as environment variables found in parameter store and then run the build on the office vpn please see the team s gatsby cloud template sites as examples staging install libxml2 with brew install libxml2 on mac and apt get install libxml2 on linux install mut https github com mongodb mut and ensure that you have properly configured your giza aws keys as defined here https github com mongodb mut blob 3df98c17b0c5ea0b6101fe2c0e1b36ebdf97412e mut authenticationinfo py l7 then from root run shell npm run build clean stage warning note this will promote the contents of your local public directory your instance in staging may break or be outdated if you haven t run npm run build before make stage staging with gatsby cloud preview if your changes specifically affect gatsby cloud preview builds set up and use your own gatsby cloud site denoted by github username in our team s organization the feature branch can be assigned to the gatsby cloud site multiple feature branches in parallel may require the use of multiple gatsby cloud sites see this wiki page https wiki corp mongodb com display de how to set up a new gatsby cloud site for help with setup releasing we have configured an automatic release process using github actions https github com features actions that is triggered by npm version https docs npmjs com cli version to release a version you must have admin privileges in this repo then proceed as follows 1 on the master branch run git pull followed by npm ci 2 run npm version major minor patch using semantic versioning https semver org guidelines to correctly increment the version number keep the minor version consistent with snooty parser versioning https github com mongodb snooty parser tags github actions will create a new git tag and push it to github 3 update the
