image nuttx bin gz insert the microsd card into pinephone power on pinephone and nuttx should theoretically boot on pinephone as mentioned earlier we should rebuild nuttx so that start is changed to

in pinephone image https lupyuen github io images fb test2 jpg the missing pixels magically appear later in a curious pattern watch the demo on youtube https www youtube com shorts wd5ajj7rz5u there seems to be a problem with framebuffer dma display engine timing controller tcon0 according to the video the pixels are actually written correctly to the ram framebuffer but the pixels at the lower half don t get pushed to the display until the next screen refresh there seems to be a lag between the writing of pixels to framebuffer and the pushing of pixels to the display over dma display engine timing controller tcon0 here s the fix for this lag fix missing pixels in pinephone image in the previous section we saw that there was a lag pushing pixels from the ram framebuffer to the pinephone display over dma display engine timing controller tcon0 can we overcome this lag by copying the ram framebuffer to itself forcing the display to refresh this sounds very strange but yes it works from

https en wikipedia org wiki data coding scheme sms data coding scheme the ucs2 encoding is actually unicode utf 16 https en wikipedia org wiki utf 16 the sms standard specifies ucs 2 but almost all users actually implement utf 16 so that emojis work source https en wikipedia org wiki utf 16 so this encoded message text text tp user data message text encoded with ucs2 character set 00480065006c006c006f002c005100750065006300740065006c0021 comes from the unicode utf 16 encoding https en wikipedia org wiki utf 16 of the message text hello quectel character utf 16 encoding h 0048 e

article nuttx rtos for pinephone phone calls and text messages https lupyuen github io articles lte2 why send sms in pdu mode instead of text mode sending sms messages in text mode looks easier but we should use pdu mode instead here s why in text mode this is how we send an sms text text mode how many characters in this sms at cmgs 1234567890 in pdu mode we do it like so text pdu mode 41 bytes in this sms excluding smsc at cmgs 41 see the difference pdu mode is more precise because we state exactly how many bytes there are in the sms with text mode there s a risk of garbled messages when characters are dropped during uart transmission which happens but what if characters are dropped in pdu mode the lte modem will say it s an invalid pdu text cms error 304 our app should catch this error and resend pinephone accelerometer and gyroscope to read pinephone s invensense mpu 6050 accelerometer and gyroscope check out this article inside a smartphone accelerometer pinephone with nuttx rtos https www hackster io lupyuen inside a smartphone accelerometer pinephone with nuttx rtos b92b58 compile nuttx on android with termux can we compile nuttx on an android phone or tablet with termux that would be really cool for checking whether the latest nuttx updates are building ok for our target device all we need is an android phone we managed to install the nuttx build tools on android termux including kconfig compile apache nuttx rtos on android with termux https gist github com lupyuen f59c681dde9ebac86b331f2577aa04ad nuttx make starts ok but it fails later because we couldn t build the gcc arm64 toolchain on android termux emulate pinephone with unicorn emulator to make pinephone testing easier can we emulate arm64 pinephone with unicorn emulator https www unicorn engine org read the articles possibly emulate pinephone with unicorn emulator https lupyuen github io articles unicorn clickable call graph for apache nuttx real time operating system https lupyuen github io articles unicorn2 emulate arm64 machine code https lupyuen github io images unicorn code png simulate pinephone ui with zig lvgl and webassembly read the articles nuttx rtos for pinephone feature phone ui in lvgl zig and webassembly https lupyuen github io articles lvgl4 possibly lvgl in webassembly with zig compiler https lupyuen github io articles lvgl3 we re now building a feature phone ui for nuttx on pinephone can we simulate the feature phone ui with zig lvgl and webassembly in a web browser to make the ui coding a little easier we have previously created a simple lvgl app with zig for pinephone pinephone lvgl zig https github com lupyuen pinephone lvgl zig zig natively supports webassembly webassembly on zig https ziglang org documentation master webassembly so we might run zig javascript in a web browser like so webassembly with zig in a web browser https dev to sleibrock webassembly with zig pt ii ei7 but lvgl doesn t work with javascript yet lvgl runs in a web browser by compiling with emscripten and sdl lvgl with emscripten and sdl https github com lvgl lv web emscripten therefore we shall do this 1 use zig to compile lvgl from c to webassembly with zig cc https github com lupyuen zig bl602 nuttx zig compiler as drop in replacement for gcc 1 use zig to connect the javascript ui canvas rendering input events to lvgl webassembly like this https dev to sleibrock webassembly with zig pt ii ei7 check out the updates here simulate pinephone ui with zig lvgl and webassembly https github com lupyuen pinephone lvgl zig simulate pinephone ui with zig lvgl and webassembly apache nuttx rtos for pinephone pro todo wip port of nuttx to pinephone pro https github com apache nuttx pull 10193 1 would be good to provide the arm64 disassembly so that i can locate the addresses also peek at the code snippets bash dump the disassembly to nuttx s aarch64 none elf objdump t s demangle line numbers wide nuttx nuttx s 2 1 2 what s the boot address kernel addr r for pinephone pro i can t find it in the docs so i assume that this value is correct c u boot loads nuttx at this address kernel addr r define config load base 0x02080000 here s how we get kernel addr r from u boot is it the same for tow boot https lupyuen github io articles uboot boot address 3 change the memory map ram and i o to this based on the address mapping from rk3399 tech ref manual part 1 page 560 https github com apache nuttx blob master arch arm64 include a64 chip h l45 l51 c ram base address i m guessing this based on config load base kernel addr r define config rambank1 addr

github com torvalds linux blob master arch arm64 boot dts rockchip rk3399 dtsi l549 l553 gicd 0xfee00000 gicr 0xfef00000 but i m not sure what s config gicr offset https github com apache nuttx blob master arch arm64 src common arm64 gicv3 c l786 l793 offset to the gic registers for each cpu maybe we stick with the current value and test whether uart interrupts https lupyuen github io articles

govtnz-design-system | new zealand government design system alpha this is the github repo for developers more documentation is available on the design system alpha website https design system alpha digital govt nz this is a new service your feedback will help us to improve it email the design system ds team at info digital govt nz mailto info digital govt nz use our nzgds slack app https nz aog design system slack com open an issue in this github repo contributions we welcome contributions to the new zealand government design system nzgds see contributing https github com govtnz govtnz design system blob master contributing md install currently the design system is hosted on npm https npmjs com although we are investigating using other distribution networks too for example packagist https packagist org if you d prefer a particular network please let us know the npm package name is govtnz ds so from an npm project https docs npmjs com cli init use the command npm i govtnz ds or yarn add govtnz ds for users of yarn https yarnpkg com to add the design system once installed the design system files can be found at node modules govtnz ds build integration type where integration type is one of the following html html css css scss scss sass react js react javascript react ts react typescript react js styled components react javascript with styled components react ts styled components react typescript with styled components silverstripe components silverstripe alpha quality vue js vue javascript beta quality vue js vue typescript beta quality mustache mustacle handlebars beta quality there may be other integration types included however these are provided for testing purposes only and to give more transparency about our intentions to support more template formats component usage this project adheres to a naming convention where a component has an id with different filename extensions for each integration type for example the h1 component has html at node modules govtnz ds build html h1 html and css at node modules govtnz ds build css h1 css for example the flexcontainer component has html at node modules govtnz ds build html flexcontainer html and css at node modules govtnz ds build css flexcontainer css and so on find the list of possible components by browsing on the design system alpha website https design system alpha digital govt nz or browsing integration type directory under node modules govtnz ds build integration type updates and versions as there will be updates we recommend that you email info digital govt nz mailto info digital govt nz to subscribe to our newsletter information about new versions will also be available on npmjs each release of the design system is given a version number adhereing to semver https semver org so that specific versions can be installed you can upgrade to later versions of the design system by typing npm i govtnz ds semver or yarn add govtnz ds semver for users of yarn https yarnpkg com where semver is the specific version string integration types html html is provided as a reference sometimes these examples may include css classes showing optional classes eg g radios inline that you may not need so consult the website documentation to ensure you re using the correct html css css may be imported directly and will include css variables https developer mozilla org en us docs web css var for some design system components there is a index css that imports every css file take care when using this without a css preprocessor as it may result in many network requests for each individual file we recommend the best practice of choosing specific css files to bundle and minify rather than including all css files scss sass scss may be imported directly and will include both sass and css variables https developer mozilla org en us docs web css var for some design system components there is a index scss that imports every scss file take care importing every file because this may result in unused scss we recommend the best practice of choosing specific scss files to bundle and minify rather than including all scss files there is a settings scss file for sass variable configuration these settings may change as we develop theming features react import from an integration type as either react js react ts react js styled components or react ts styled components you can then name the specific component you wish to install eg for the h1 component javascript import h1 from govtnz ds build react js h1 js you may import css as import govtnz ds build css h1 css or scss as import govtnz ds build css h1 scss or include those classes via some other scss or css preprocessor for styled components https www styled components com you do not need to import css or scss read the component source code or use the typescript types to learn about the props each component accepts silverstripe please note that our silverstripe components are currently alpha quality we recommend using html until we can give you guidance on how to integrate specific technologies however if you wish to help us test these components they are available at node modules govtnz ds build silverstripe components as ss template files we intend to use the silverstripe components https github com symbiote silverstripe components syntax however there are currently bugs in this library that prevent us from using it we have two boilerplate sites included in this repo under packages for both silverstripe 3 and silverstripe 4 that show potential silverstripe components integrations vue after installation use files as javascript import h1 from govtnz ds build vue js h1 vue these vue files currently include css should they let us know read the component source code or use the typescript types to learn about the variables each component accepts mustache mustache https mustache github io handlebars https handlebarsjs com template files are included as an integration type we have a boilerplate demo included in this repo under packages for mustache mustache templates can be converted into html by using a mustache or handlebars template processor these processors accept a mustache template string and an object of properties to apply to the template called a context when providing a context value that sets an enumeration a multichoice option provide the value as option value true option true where option is the enumerated key and value is the enumerated value this is required because mustache is a logic less template format that has no way of comparing values so the enumeration must be precomputed some mustache templates use triple bracket variable which bypasses html escaping this is necessary because some variables are expected to render html not just text nodes or attribute values be careful to encode input to avoid security issues https github com owasp cheatsheetseries blob master cheatsheets cross site scripting prevention cheat sheet md why cant i just html entity encode untrusted data when using mustache templates other formats what other formats would you like us to support please let us know see contact details at the top of this

recent years we ve see an extra ordinary growth in computer vision with applications in face recognition image understanding search drones mapping semi autonomous and autonomous vehicles a key part to many of these applications are visual recognition tasks such as image classification object detection and image similarity this repository provides examples and best practice guidelines for building computer vision systems the goal of this repository is to build a comprehensive set of tools and examples that leverage recent advances in computer vision algorithms neural architectures and operationalizing such systems rather than creating implementations from scratch we draw from existing state of the art libraries and build additional utility around loading image data optimizing and evaluating models and scaling up to the cloud in addition having worked in this space for many years we aim to answer common questions point out frequently observed pitfalls and show how to use the cloud for training and deployment we hope that these examples and utilities can significantly reduce the time to market by simplifying the experience from defining the business problem to development of solution by orders of magnitude in addition the example notebooks would serve as guidelines and showcase best practices and usage of the tools in a wide variety of languages these examples are provided as jupyter notebooks scenarios and common utility functions utils cv all examples use pytorch as the underlying deep learning library examples this repository supports various computer vision scenarios which either operate on a single image p align center img src scenarios media cv overview jpg height 350 alt some supported cv scenarios p as well as scenarios such as action recognition which take a video sequence as input p align center img src scenarios action recognition media action recognition2 gif example of action recognition p target audience our target audience for this repository includes data scientists and machine learning engineers with varying levels of computer vision knowledge as our content is source only and targets custom machine learning modelling the utilities and examples provided are intended to be solution accelerators for real world vision problems getting started to get started navigate to the setup guide setup md which lists instructions on how to setup the compute environment and dependencies needed to run the notebooks in this repo once your environment is setup navigate to the scenarios scenarios folder and start exploring the notebooks we recommend to start with the image classification notebooks since this introduces concepts which are also used by the other scenarios e g pre training on imagenet alternatively we support binder binder https mybinder org badge logo svg https mybinder org v2 gh patrickbue computervision recipes master filepath scenarios 2fclassification 2f01 training introduction binder ipynb which makes it easy to try one of our notebooks in a web browser simply by following this link however binder is free and as a result only comes with limited cpu compute power and without gpu support expect the notebook to run very slowly this is somewhat improved by reducing image resolution to e g 60 pixels but at the cost of low accuracies scenarios the following is a summary of commonly used computer vision scenarios that are covered in this repository for each of the main scenarios base we provide the tools to effectively build your own model this includes simple tasks such as fine tuning your own model on your own data to more complex tasks such as hard negative mining and even model deployment scenario support description classification scenarios classification base image classification is a supervised machine learning technique to learn and predict the category of a given image similarity scenarios similarity base image similarity is a way to compute a similarity score given a pair of images given an image it allows you to identify the most similar image in a given dataset detection scenarios detection base object detection is a technique that allows you to detect the bounding box of an object within an image keypoints scenarios keypoints base keypoint detection can be used to detect specific points on an object a pre trained model is provided to detect body joints for human pose estimation segmentation scenarios segmentation base image segmentation assigns a category to each pixel in an image action recognition scenarios action recognition base action recognition to identify in video webcam footage what actions are performed e g running opening a bottle and at what respective start end times we also implemented the i3d implementation of action recognition that can be found under contrib contrib tracking scenarios tracking base tracking allows to detect and track multiple objects in a video sequence over time crowd counting contrib crowd counting contrib counting the number of people in low crowd density e g less than 10 people and high crowd density e g thousands of people scenarios we separate the supported cv scenarios into two locations i base code and notebooks within the utils cv and scenarios folders which follow strict coding guidelines are well tested and maintained ii contrib code and other assets within the contrib folder mainly covering less common cv scenarios using bleeding edge state of the art approaches code in contrib is not regularly tested or maintained computer vision on azure note that for certain computer vision problems you may not need to build your own models instead pre built or easily customizable solutions exist on azure which do not require any custom coding or machine learning expertise we strongly recommend evaluating if these can sufficiently solve your problem if these solutions are not applicable or the accuracy of these solutions is not sufficient then resorting to more complex and time consuming custom approaches may be necessary the following microsoft services offer simple solutions to address common computer vision tasks vision services https docs microsoft com en us azure cognitive services computer vision are a set of pre trained rest apis which can be called for image tagging face recognition ocr video analytics and more these apis work out of the box and require minimal expertise in machine learning but have limited customization capabilities see the various demos available to get a feel for the functionality e g computer vision https azure microsoft com en us services cognitive services computer vision analyze the service can be used through api calls or through sdks available in net python java node and go languages custom vision https docs microsoft com en us azure cognitive services custom vision service home is a saas service to train and deploy a model as a rest api given a user provided training set all steps including image upload annotation and model deployment can be performed using an intuitive ui or through sdks available in net python java node and go languages training image classification or object detection models can be achieved with minimal machine learning expertise the custom vision offers more flexibility than using the pre trained cognitive services apis but requires the user to bring and annotate their own data if you need to train your own model the following services and links provide additional information that is likely useful azure machine learning service azureml https docs microsoft com azure machine

witness node witness node under build directory the node run will automatically create the directory witness node data dir along with config files underneath then start synchronizing the blockchain it may take usually several hours to fully synchronize the blockchain data the blockchain data will be stored under the directory witness node data dir stop node software for stopping the node run cleanly you will need to access the node run terminal then press on ctrl c then wait for the run to stop please note that it may take usually few minutes to exit the run it s recommended to use linux command screen https help ubuntu com community screen to initiate the node run so you can go back to the node run screen to stop it important by default the node will start in reduced memory mode by using some of the commands detailed in memory reduction for nodes https github com bitshares bitshares core wiki memory reduction for nodes in order to run a full node with all the account histories which usually unnecessary you need to remove partial operations and max ops per account from your config file please note that currently 2018 10 17 a full node will need more than 160gb of ram to operate and required memory is growing fast consider the following table as minimal requirements before running a node default full minimal elasticsearch 150g hdd 16g ram 640g ssd 64g ram 120g hdd 4g ram 1tb ssd 32g ram for this setup allocate at least 500gb of ssd as swap to use the command line wallet or other wallets clients with the node the node need to be started with rpc connection enabled which can be done by starting the node with the rpc endpoint parameter e g programs witness node witness node rpc endpoint 127 0 0 1 8090 or configure it in the config file by editing witness node

id and a name when running witness node with rpc connection enabled initially two api sets are available api set with id 0 has name database it provides read only access to the database api set with id 1 has name login it is used to login and gain access to additional restrictable api sets here is an example using wscat package from npm for websockets npm install g wscat wscat c ws 127 0 0 1 8090

params id 1 http 127 0 0 1 8093 curl data jsonrpc 2 0 method get account params 1 2 0 id 1 http 127 0 0 1 8093 note the syntax to access wallet api is a bit different than accessing node api important when rpc connection is enabled for cli wallet sensitive data e g private keys which is accessible via commands will be accessible via rpc too it is recommended that only open network connection to localhost or trusted addresses e g configure a firewall when using wallet api sensitive data e g the wallet password and private keys is transmitted as plain text thus may be vulnerable to network sniffing it is recommended that only use wallet api with localhost or in a clean network and or use rpc tls endpoint parameter to only serve wallet api via secure connections accessing restrictable node api sets you can restrict node api sets to particular users by specifying an api access file in config ini or by using the api access full path to api access json command line option on node startup here is an example api access file which allows user bytemaster with password supersecret to access four different api sets while allowing any other user to access the three public api sets necessary to use the node permission map bytemaster password hash b64 9e9gf7ooxvb9k4bosfniptelxegoz5drgoymj94elay password salt b64 inddm6ici 8 allowed apis database api network broadcast api history api network node api password hash b64 password salt b64 allowed apis database api network broadcast api history api note the login api set is always accessible passwords are stored in base64 as salted sha256 hashes a simple python script saltpass py https github com bitshares bitshares core blob master programs witness node saltpass py is available to obtain hash and salt values from a password a single asterisk may be specified as username or password hash to accept any value with the above configuration here is an example of how to call the add node api from the network node api set id 1 method call params 1 login bytemaster supersecret id 2 method call params 1 network node id 3 method call params 2 add node 127 0 0 1 9090 note the call to network node is necessary to obtain the correct api set id for the network node api set it is not guaranteed that the api set id for the network node api set will always be 2 the restricted api sets are accessible via http too using basic access authentication e g curl data jsonrpc 2 0 method call params network node add node 127 0 0 1 9090 id 1 http bytemaster supersecret 127 0 0 1 8090 our doxygen documentation contains the most up to date information about apis for the node https bitshares github io doxygen namespacegraphene 1 1app html and the wallet https bitshares github io doxygen classgraphene 1 1wallet 1 1wallet api html faq is there a way to generate help with parameter names and method descriptions yes documentation of the code base including apis can be generated using doxygen simply run doxygen in this directory if both doxygen and perl are available in your build environment the command line wallet s help and gethelp commands will display help generated from the doxygen documentation if your command line wallet s help command displays descriptions without parameter names like signed transaction transfer string string string string string bool it means cmake was unable to find doxygen or perl during configuration if found the output should look like this signed transaction transfer string from string to string amount string asset symbol string memo bool broadcast is there a way to allow external program to drive cli wallet via websocket jsonrpc or http yes external programs may connect to the command line wallet and make its calls over a websockets api to do this run the wallet in server mode i e cli wallet h 127 0 0 1 9999 and then have the external program connect to it over the specified port in this example port 9999 please check the using built in apis using built in apis section for more info is there a way to access methods which require login over http yes most of the methods can be accessed by specifying the api name instead of an api id if an api is protected by a username and a password it can be accessed by using basic access authentication please check the accessing restrictable node api sets accessing restrictable node api sets section for more info however http is not really designed for server push notifications and we would have to figure out a way to queue notifications for a polling client websockets solves this problem if you need to access the stateful methods use websockets what is the meaning of a b c numbers the first number specifies the space space 1 is for protocol objects 2 is for implementation objects protocol space objects can appear on the wire for example in the binary form of transactions implementation space objects cannot appear on the wire and solely exist for implementation purposes such as optimization or internal bookkeeping the second number specifies the type the type of the object determines what fields it has for a complete list of type ids see graphene define ids protocol protocol ids in protocol types hpp https github com bitshares bitshares core blob master libraries protocol include graphene protocol types hpp and graphene define ids chain implementation ids in chain types hpp https github com bitshares bitshares core blob master libraries chain include graphene chain types hpp the third number specifies the instance the instance of the object is different for each individual object the answer to the previous question was really confusing can you make it clearer all account ids are of the form 1 2 x if you were the 9735th account to be registered your account s id will be 1 2 9735 account 0 is special it s the committee account which is controlled by the committee members and has a few abilities and restrictions other accounts do not all asset ids are of the form 1 3 x if you were the 29th asset to be registered your asset s id will be 1 3 29 asset 0 is special it s bts which is considered the core asset the first and second number together identify the kind of thing you re talking about 1 2 for accounts 1 3 for assets the third number identifies the particular thing how do i get the network add nodes command to work why is it so complicated you need to follow the instructions in the accessing restrictable node api sets accessing restrictable node api sets section to allow a username password access to the network node api set then you need to pass the username password to the cli wallet on the command line it s set up this way so that the default configuration is secure even if the rpc port is publicly accessible it s fine if your witness node allows the general public to query the database or broadcast transactions in fact this is how the hosted web ui works it s less fine if your witness node allows the general public to control which p2p nodes it s connecting to therefore the api to add p2p connections needs to be set up with proper access controls license bitshares core is under the mit license see license https github com bitshares bitshares

are associated with substantial morbidity mortality and cost manual identification of infections is costly time consuming and diverts staff time from prevention activities although next generation dna sequencing has demonstrated its ability to identify microbial pathogens where traditional diagnostics have otherwise failed there are several limitations to use it for infection detection in clinical setting 1 the volume of data that is produced from next generation sequencing platforms is massive 2 data analysis is time consuming and requires sophisticated bioinformatics systems 3 the lack of computational resources for large dataset storage and management limits capability to analyze and clinically interpret the data tools and technologies used 1 aws s3 2 apache spark 3 airflow 4 aws

from 15 18 body sites from 300 human subjects they provide access to raw mwgs sequence data in fastq format data process this cloud based platform contains two pipelines the first pipeline collects and analyzes large scale genomic datasets to generate diagnosis for infection automatically the other pipeline is designed as distributed data mining systerm to review and process millions of patients medical records efficiently these pipelines utilized spark and redshift to process raw data and build a data warehouse for designing individualized treatment strategies and monitoring infection outbreaks by elastically scaling the number and types of compute instances in addition to optimization of pipelines to run in parallel there are no limits to the amount of data you can analyze airflow jobs a scheduler would be running to collect the data from s3 to spark jobs every two hours the raw sequencing data is collected and processed to get accurate diagnosis for infection at the sametime detailed healthcare information for patients is processed and saved to data warehouse all those data is further analyzed and posted to the dashboard dynamicaly ui design two tier data sharing application for both public health care management and clinical report dashboard allowing clinicians to better protect patients by identifying and investigating potential clusters of infections daily reports will be generated from the collected data a detailed summary of infection type patient s metadata and previous medical records would be available to the doctors for further analysis

ml4a-ofx | ml4a ofx a collection of real time interactive applications and associated scripts for working with machine learning all apps contained here require openframeworks http www openframeworks cc to run as well as a number of addons listed below organization the openframeworks apps are provided as source code and can be built and compiled by using the project generator that comes with openframeworks several of these applications are coupled with python scripts which do some analysis of media feature extraction t sne etc whose results are then imported into your ofapp via json or some other means for further processing some of them can be replicated entirely within openframeworks and wherever possible for example t sne such applications are also provided the advantage of the scripts is that they can be used in other environments as well and are much easier to port or implement from the preeminent machine learning frameworks applications the apps https github com ml4a ml4a ofx tree master apps folder contains all of the individual openframeworks apps and their descriptions and usage instructions osc modules the osc modules https github com ml4a ml4a ofx tree master osc modules folder contains a set of applications which send or receive osc in order to facilitate communication with other applications and are very easily used alongside wekinator http www wekinator org datasets some of the applications work on image audio text datasets example datasets are provided and can be downloaded with the provided scripts see download images py for image example additionally some require pre trained models which can also be downloaded for the ones which require vgg weights you can download that here https drive google com file d 0bz7kyqmugsilt0j5dmrcm0rovhc view usp sharing addons all of the included applications both in the apps and osc modules folders require some combination of the following addons the readme for each app lists the addons required individually

ofxtsne https github com genekogan ofxtsne the addons also make use of ofxgui ofxosc and ofxopencv which are included in openframeworks by default these addons are not currently used in ml4a ofx but are also relevant and may be wrapped into examples in the future ofxmsatensorflow https github com memo ofxmsatensorflow ofxdlib https github com bakercp ofxdlib ofxcaffe https github com geekrick88 ofxcaffe getting started these are some steps to get you up and running with ml4a ofx prepare your project 0 make sure you ve read and followed the openframeworks setup guides http openframeworks cc download relevant for your system going through them makes sure the foundation for all ml4a ofx apps is working correctly 1 this guide assumes that you have one folder with the openframeworks setup in it this is the folder in which you would test your openframeworks setup as described above one different folder in which you have the ml4a ofx content this folder does not have to be within the openframeworks folder 1 for your project you most certainly want to use an existing ml4a ofx app as a starting point so simply duplicate any of the folders within ml4a ofx apps and give the folder a custom name or work in the folder of the example project if you do not plan to re use it anyways 1 check the readme md file of your project it always contains the required addons you need to get your app running follow the links of each addon check the installation guide and follow each one some of the apps need example data to work correctly as you probably have enough space on your computer anyways open a terminal window go into the ml4a ofx folder and run sh setup sh this will download the necessary data and place it in the data folder all addons currently used across the examples are mentioned in the addons list addons be careful put the required addons into the addons subfolder of your openframeworks folder to work correctly setup your project on a mac you can use the projectgenerator app that is included in openframeworks set the base path to your openframeworks folder as described in the app this has to be done on the first time only click on the create update tab import your project by clicking the import button selecting your project s folder this should be located in your ml4a ofx folder your project name project path and the addons list should update accordingly if any of the addons is missing the interface will notify you of that since you prepared your project in the above described steps all should be good here otherwise check the prepare your project part again click update to get the project setup running the interface doesn t show it explicitly but this gets the project generator running it should result in a success message you can then click open in ide to directly open the project in xcode also feel free to close the projectgenerator again since you don t need it anymore for now within xcode wait a few moments to index and process the files of the project you can then compile the project by pressing the play button or cmd r cross your fingers fingers crossed and hope your project compiles wink if you run into any errors the openframeworks setup guides might have some explanations or possible steps otherwise it always helps to google the error seriously and try to figure out what s going on in case you get completely stuck you might find help here by opening an issue https github com ml4a ml4a ofx issues new include any error message you find and try to explain the problem as good as possible this will help resolve any issue a lot on windows feel free to add documentation here on linux feel free to add documentation here | ai |

crect | crect a c compile time reactive rtos crect pronounced correct is a c library for generating a scheduler at compile time for cortex m series mcus which guarantees dead lock free and data race free execution it utilizes the nested vector interrupt controller nvic in cortex m processors to implement a stack resource policy srp based scheduler thanks to the compile time creation of the scheduler the resource requirements at run time are minimal with initialization 4 5 instructions job for initialization of the nvic 2 3 instructions queue element for initializing the async queue the static requirement for async is about 400 bytes the linked list systick and time implementation compile time uses the kvasir mpl library for metaprogramming runtime 3 4 instructions 4 bytes of stack for a lock 1 3 instructions for an implicit unlock claim has zero overhead it decomposes into a lock 5 instructions for a unique lock will change 2 instructions for a unique unlock will change 2 4 instructions for pend clear about 20 30 instructions number of items in queue for async in this scheduler heavy use of c metaprogramming and c 14 allows among other things priority ceilings and interrupt masks to be automatically calculated at compile time while resource locks are handled through raii and resource access is handled via a monitor pattern this minimizes user error without the need for an external extra compile step as is currently being investigated in the rtfm core language http www rtfm lang org videos tutorials youtube video from embo 2018 https www embo io describing the inner workings of crect https www youtube com watch v sbij9w9gfbw give it a test in the example folder a few example projects are setup for the nucleo f411re board for example a program that will blink a led every one seconds using crect primitives an example for how to use unique lock with a data pumping peripheral for example dma or a communication interface it also contains examples of crect system config hpp and crect user config hpp providing references until a documentation is available if there are any questions on the usage throw me a message tested on ubuntu linux using gcc 6 3 1 arm none eabi and a nucleo f411re for hardware testing it is currently not working on cortex m0 devices license boost software license version 1 0 contributors list of contributors in alphabetical order emil fresk https www github com korken89 odin holmes https www github com odinthenerd carlos van rooijen https www github com cvrxx references crect is based on the following academic papers t p baker a stack based resource allocation policy for realtime processes general theory of srp johan eriksson et al real time for the masses step 1 programming api and static priority srp kernel primitives srp primitives per lindgren et al abstract timers and their implementation onto the arm cortex m family of mcus async idea definitions job a function that runs to completion in a finite time no forever loop not as a normal thread that has a forever loop has a settable priority which indicates the urgency of the job resource an entity symbolizing something lockable i e any locked resource may only be accessed by a single job at a time lock a lock on a resource keeps other jobs that will also take said resource from running through manipulation of the systems nvic basepri settings a lock can only be held within a job and must be released before the exit of a job usage small description on how to use this resource definition a resource definition is as follows c using rled crect make resource crect object link led resource link to some object to be protected currently 2 system resources exists 1 the access to the async queue is protected via crect rasync 2 for getting the current time via crect clock system now is protected via crect rsystem clock see claim for example usage any job using these resources need to have the corresponding resource in its resource claim in crect user config hpp job definition a job definition consists of a few parts 1 the priority of the job from 0 meaning low to max priority meaning max 2 an isr the job is connected to peripheral isrs 0 is the lowest negative numbers are the system isrs if it is not connected to any take any random isr number for now in the future this will be automatic 3 the list of resources that the job may claim the job definitions are placed directly or via include in crect user config hpp c void job1 void using j1 crect job 1 priority 0 low crect make isr job1 1 isr connection and location r1 crect rasync list of possible resource claims each job need to be added to the user job list jobs in crect user config hpp isr definition the isr definitions available are split in the peripheral isrs i 0 and system isrs i 0 c peripheral isr definition i 0 template crect details isr function pointer p int i using make isr crect details isr p crect details index i system isr definition i 0 template int i using make system isr crect details isr nullptr crect details index i lock a lock keeps the system from running a job which will lock the same resource the analysis to determine which job can take which resource is done at compile time which makes the lock very cheap to use as indicated at the start of this document lock should however be avoided by the user use claim wherever possible c lock the resource remember locks are very cheap sprinkle them everywhere crect lock r1 lock locks are made in the constructor of the lock unlock is automatic in the destructor of lock there is no unlock this is by design claim even with lock it is easy to leak a resource and to minimize this chance claim uses a monitor pattern to guard the resource hence the resource is only available within the lambda of claim c access the led resource through the claim following a monitor pattern just as cheap as a lock crect claim rled auto led led enable to guarantee the lock for resources with a return works just as good with claim for example when getting the current time as the system time is a shared resource c resource is handled within the claim no risk of a data race auto current time crect claim crect rsystem clock auto now return now now is a function reference for a full example please see examples blinky unique lock add a unique resource and its corresponding lock is to support lock over job boundaries this allows for producer consumer patterns as the unique job can work by reading a queue of actions ex a dma where jobs push to a dma transfer queue and the job which has the unique dma resource will read this queue and perform the desired transactions a unique lock effectively decomposes into disabling the interrupt vector of the job while the unique unlock re enables the interrupt vector for a full example please see examples unique c there is no unlock this is by design pend clear pend directly sets a job for execution and will be as soon as its priority is the highest while clear removes the job for execution c compile time constant pend clear crect pend jobtopend crect clear jobtopend runtime dependent pend clear crect pend

system user cases description of sequences of events that taken together lead to a system doing something useful who is going to use it how are they going to use it constraints mainly identify traffic and data handling constraints at scale scale of the system such as requests per second requests types data written per second data read per second special system requirements such as multi threading read or write oriented 2 high level architecture design abstract design sketch the important components and connections between them but don t go into some details application service layer serves the requests list different services required data storage layer eg usually a scalable system includes webserver load balancer service service partition database master slave database cluster and caching systems 3 component design component specific apis required for each of them object oriented design for functionalities map features to modules one scenario for one module consider the relationships among modules certain functions must have unique instance singletons core object can be made up of many other objects composition one object is another object inheritance 4 database schema design understanding bottlenecks perhaps your system needs a load balancer and many machines behind it to handle the user requests or maybe the data is so huge that you need to distribute your database on multiple machines what are some of the downsides that occur from doing that is the database too slow and does it need some in memory caching 5 scaling vertical scaling you scale by adding more power cpu ram to your existing machine horizontal scaling you scale by adding more machines into your pool of resources caching load balancing helps you scale horizontally across an ever increasing number of servers but caching will enable you to make vastly better use of the resources you already have as well as making otherwise unattainable product requirements feasible application caching requires explicit integration in the application code itself usually it will check if a value is in the cache if not retrieve the value from the database database caching tends to be free when you flip your database on you re going to get some level of default configuration which will provide some degree of caching and performance those initial settings will be optimized for a generic usecase and by tweaking them to your system s access patterns you can generally squeeze a great deal of performance improvement in memory caches are most potent in terms of raw performance this is because they store their entire set of data in memory and accesses to ram are orders of magnitude faster than those to disk eg memcached or redis eg precalculating results e g the number of visits from each referring domain for the previous day eg pre generating expensive indexes e g suggested stories based on a user s click history eg storing copies of frequently accessed data in a faster backend e g memcache instead of postgresql load balancing public servers of a scalable web service are hidden behind a load balancer this load balancer evenly distributes load requests from your users onto your group cluster of application servers types smart client hard to get it perfect hardware load balancers but reliable software load balancers hybrid works for most systems p align center img src http lethain com static blog intro arch load balance png alt load balancing p database replication database replication is the frequent electronic copying data from a database in one computer or server to a database in another so that all users share the same level of information the result is a distributed database in which users can access data relevant to their tasks without interfering with the work of others the implementation of database replication for the purpose of eliminating data ambiguity or inconsistency among users is known as normalization database partitioning partitioning of relational data usually refers to decomposing your tables either row wise horizontally or column wise vertically map reduce for sufficiently small systems you can often get away with adhoc queries on a sql database but that approach may not scale up trivially once the quantity of data stored or write load requires sharding your database and will usually require dedicated slaves for the purpose of performing these queries at which point maybe you d rather use a system designed for analyzing large quantities of data rather than fighting your database adding a map reduce layer makes it possible to perform data and or processing intensive operations in a reasonable amount of time you might use it for calculating suggested users in a social graph or for generating analytics reports eg hadoop and maybe hive or hbase platform layer services separating the platform and web application allow you to scale the pieces independently if you add a new api you can add platform servers without adding unnecessary capacity for your web application tier adding a platform layer can be a way to reuse your infrastructure for multiple products or interfaces a web application an api an iphone app etc without writing too much redundant boilerplate code for dealing with caches databases etc p align center img src http lethain com static blog intro arch platform layer png alt platform layer p div

webpages and other web content to a user based on the geographic locations of the user the origin of the webpage and a content delivery server this service is effective in speeding the delivery of content of websites with high traffic and websites that have global reach the closer the cdn server is to the user geographically the faster the content will be delivered to the user cdns also provide

openbalena are there security patches on openbalena openbalena is an open source initiative which is mostly driven by us but it also gets contributions from the community we work to keep openbalena as up to date as our bandwidth allows especially with security patches that said we do not have a policy or guarantee of a software release schedule however it is in our best interest to keep openbalena updated and patched since we also use it for balenacloud how do you ensure the join command actually works between open and cloud the join command is not only used for moving from openbalena to balenacloud but it is used daily by our developers to move devices from developments and testing instances to production and vice versa the join command actually wraps the os config command which is the basic tool balena uses for configuring devices is it production ready while we actually have some rather large fleets using openbalena we as a company consider it still to be in beta status we don t perform regular testing on the platform like we do balenacloud and we do not yet have feature parity between the various services we offer can new device types be added to openbalena technically yes but in a supported or balena recommended fashion no the main reason is that until we regularly test the openbalena platform the way we do balenacloud there s no scalable way for us to provide support
