I am using the python libraries from the Assistant SDK for speech recognition via gRPC. I have the speech recognized and returned as a string calling the method resp.result.spoken_request_text from \googlesamples\assistant\__main__.py and I have the answer as an audio stream from the assistant API with the method resp.audio_out.audio_data also from \googlesamples\assistant\__main__.py I would like to know if it is possible to have the answer from the service as a string as well (hoping it is available in the service definition or that it could be included), and how I could access/request the answer as string. Thanks in advance.

Currently (Assistant SDK Developer Preview 1), there is no direct way to do this. You can probably feed the audio stream into a Speech-to-Text system, but that really starts getting silly. Speaking to the engineers on this subject while at Google I/O, they indicated that there are some technical complications on their end to doing this, but they understand the use cases. They need to see questions like this to know that people want the feature. Hopefully it will make it into an upcoming Developer Preview.

I don't know of any way, but: To use the api the free/demo version is enough! If you can not install it on your machine due to missing privileges, etc... You can also copy the installation from another machine. You might need to tell the api-implementation then where to find your gams "installation".

I am trying to spawn a mapreduce job using the mrjob library from AWS Lambda. The job takes longer than the 5 minute Lambda time limit, so I want to execute a remote job. Using the paramiko package, I ssh'd onto the server and ran a nohup command to spawn a background job, but this still waits until the end of job. Is there anyway to do this with Lambda?

Instead of using SSH I've solved this before by pushing a message onto a SQS queue that a process on the server monitors. This is much simpler to implement and avoids needing to keep credentials in the lambda function or place it in a VPC.

I am trying to build a node app which calls python script (takes a lot of time to run).User essentially chooses parameters and then clicks run which triggers event in socket.on('python-event') and this runs python script.I am using sockets.io to send real-time data to the user about the status of the python program using stdout stream I get from python.But the problem I am facing is that if the user clicks run button twice, the event-handdler is triggered twice and runs 2 instances of python script which corrupts stdout.How can I ensure only one event-trigger happens at a time and if new event trigger happens it should kill previous instance and also stdout stream and then run new instance of python script using updated parameters.I tried using socket.once() but it only allows the event to trigger once per connection.

How can I catch a request that is forbidden by robots.txt in scrapy? Usually this seems to get ignored automatically, i.e. nothing in the output, so I really can't tell what happens to those urls. Ideally if crawling a url leads to this forbidden by robots.txt error, I'd like to output a record like {'url': url, 'status': 'forbidden by robots.txt'}. How can I do that? New to scrapy.

I want to make a comparison list between different libraries for TCP packet capturing, replaying and monitoring. I have come across several libraries and cannot decide with which I should start working. I want to compare pros and cons of these libraries so that its easier for me to decide.

I guess you are trying to work with python. Here's a list of the libraries: pypcap: not maintened, the last update was in 2015 pcap_ylg: even older... updated 4 years ago pcapy: recently updated. quite low level library, hard to use for beginners pcap/pylibpcap: again, so old... The best choice seems to be scapy, which has tons of options and is easy-to-use. There are currently two versions of scapy: the original scapy: active dev. supporting all python versions and high level library for any pcap Apis scapy3k: a scapy fork which used to support python 3, but that has not recieved scapy's new features/updates since 2015

When the content-type of the server is 'Content-Type:text/html', requests.get() returns improperly encoded data. However, if we have the content type explicitly as 'Content-Type:text/html; charset=utf-8', it returns properly encoded data. Also, when we use urllib.urlopen(), it returns properly encoded data. Has anyone noticed this before? Why does requests.get() behave like this?

The default assumed content encoding for text/html is ISO-8859-1 aka Latin-1 :( See RFC-2854. UTF-8 was too young to become the default, it was born in 1993, about the same time as HTML and HTTP. Use .content to access the byte stream, or .text to access the decoded Unicode stream. If the HTTP server does not care about the correct encoding, the value of .text may be off.

You could certainly write an AWS Lambda function that would: Download the file from the URL and store it in /tmp Upload to Amazon S3 using the AWS S3 SDK It would be easiest to download the complete file rather than attempting to stream it in 'bits'. However, please note that there is a limit of 500MB of disk space available for storing data. If your download is larger than 500MB, you'll need to do some creative programming to download portions of it and then upload it as a multi-part upload. As for how to download it, use whatever library you prefer for download a web file.

Yes, you need to log in to be able to run the API. Once you log off, you can still pull data as long as you don't log onto a different computer. That's by design. So there is no other solution than either manually logging onto your terminal in the morning or making sure that you don't use Bloomberg Anywhere on another PC.

I'm working on a project and I just wanted to know what route (If I'm not going down the correct route) I should go down in order to successfully complete this project. Ferry Time: This application uses boat coordinates and ETA algorithms to determine when a boat will be approaching a certain destination. Now, I've worked up a prototype that works, but not the way I want it to. In order for my ETA's to show up on my website accurately, I have a python script that runs every minute to webscrape these coordinates from a specific site, do an algorithm, and spit out an ETA. The ETA is then sent to my database, where I display it on my website using PHP and SQL. The ETA's only update as long as this script is running (I literally run the script on Eclipse and just leave it there) Now my question: Is there a way I can avoid running the script?

i'm using a python client that makes request to a push server, and has the option to use certificates with the lib OpenSSL for python(pyopenssl), but this client ask me for the private key(can be on the same file or different path. already checked with another server that i have both cert and key). but for the "real" server they are using self-signed cert and they don't have any private key in the same file or another one as far as they told me, they just share with me this cert file, is there any way to use this kind of cert with OpeenSSL in python?, thanks

In order to use a client certificate, you must have a private key. You will either sign some quantity with your private key or engage in encrypted key agreement in order to mutually agree on a key. Either way, the private key is required. It's possible though that rather than using client certificates they use something like username/password and what they have given you is not a certificate for you to use, but the certificate you should expect from them.

Thanks Yaron

You have two options. First, you can put the two sets of items in two different files in the /models folder. Model files are executed in alphabetical order, so you can put together the final response.menu object in the second of the two files (any variables defined in the first model file will be available globally in the second file, without any need to import). Alternatively, you can put one of the sub-menus in a module (in the /modules folder) and simply import it where needed.

I read the Flask doc, it said whenever you need to access the GET variables in the URL, you can just import the request object in your current python file?

false

44,337,390

Just wanted to highlight one more fact about the requests object. As per the documentation, it is kind of proxy to objects that are local to a specific context. Imagine the context being the handling thread. A request comes in and the web server decides to spawn a new thread (or something else, the underlying object is capable of dealing with concurrency systems other than threads). When Flask starts its internal request handling it figures out that the current thread is the active context and binds the current application and the WSGI environments to that context (thread). It does that in an intelligent way so that one application can invoke another application without breaking.

No, that is not possible for two reasons: Python is a server side language that is not executed in the user's browser Even if you did use a client side language that runs in the user's browser (i.e. JavaScript), security restrictions prevent this Think of the implications if this were possible: Would you want any company whose website you are accessing to be able to spy on you like that?

TL;DR: If I spawn 10 web requests, each on its own thread, with a CPU that has a 4 thread limit, is this okay or inefficient? Threads are IO bound so sit idle while awaiting server response (I believe). How does CPU deal if more than 4 threads return simultaneously? I've got a script that currently starts a new thread for every file I need to download (each located at a unique URL) through an http.client.HTTPSConnection. At max, I may need to spawn 730 threads. I have done this, since the threads are all IO bound work (downloading and saving to file), but I am not sure if they are executing in parallel or if the CPU is only executing a set at a time. Total run time for file sizes ranging between 20MB to 110MB was roughly 15 minutes. My CPU is quad-core with no Hyper-Threading. This means that it should only support 4 threads simultaneously at any given time. Since the work is IO bound and not CPU bound, am I still limited by the hold of only 4 simultaneous threads? I suppose what is confusing is I am not sure what sequence of events takes place if say I send out just 1 request on 10 threads; what happens if they all return at the same time? Or how does the CPU choose which 4 to finish before moving onto the next available thread? And after all of this, if the CPU is only handling 4 threads at a time, I would image it is still smart to spawn as many IO threads as I need (since they will sit idle while waiting for server response) right?

You can have significantly more than 4 IO-bound threads on a quad-core CPU. However, you do want to have some maximum. Even IO bound processes use the CPU some of the time. For example, when a packet is received, that packet needs to be handled to update TCP state. If you are reading from a socket and writing to a file, some CPU is required to actually copy the characters from the socket buffer to the file buffer under most circumstances. If you use TLS, CPU is typically required to decrypt and encrypt data. So even threads that are mostly doing IO use the CPU some. Eventually the small fraction of time that you are using the CPU will add up and consume the available CPU resources. Also, note that in Python, because of the global interpreter lock, you can only have one thread using the CPU to run python code at a time. So, the GIL would not typically be held while doing something like waiting for an outgoing connection. During that time other threads could be run. However, for some fraction of the time while reading and writing from a socket or file, the GIL will be held. It's likely with most common work loads that the performance of your application will reach a maximum when the fraction of time your threads need a CPU reaches one full CPU rather than four full CPUs. You may find that using asyncio or some other event-driven architecture provides better performance. When true this is typically because the event-driven model is better at reducing cross-thread contention for resources. In response to your question edit, I would not expect 10 threads to be a problem

I recently updated from Python 3.5 to Python 3.6 and am trying to use packages that I had previously downloaded, but they are not working for the updated version of Python. When I try to use pip, I use the command "pip install selenium" and get the message "Requirement already satisfied: selenium in /Users/Jeff/anaconda/lib/python3.5/site-packages" How do I add packages to the new version of Python?

First, make sure that your packages do have compatibility with the version of Python you're looking to use. Next, run pip freeze > requirements.txt in the base directory of your Python project. This puts everything in a readable file to re-install from. If you know of any packages that require a certain version that you'll want to re-install, put package==x.x.x (where package is the package name and x.x.x is the version number) in the list of packages to make sure it downloads the correct version. Run pip uninstall -r requirements.txt -y to uninstall all packages. Afterwards, run pip install -r requirements.txt. This allows you to keep packages at the correct version for the ones you assign a version number in requirements.txt, while upgrading all others.

I have a quick question in regards to the Netmiko module (based on the Paramiko module). I have a for loop that iterates through a bunch of Cisco boxes (around 40)...and once they complete I get the following each time a SSH connection establishes: SSH connection established to ip address:22 Interactive SSH session established This isn't in my print statements or anything, it's obviously hard coded within ConnectionHandler (which I use to make the SSH connections). This output really makes my output muddled and full of 40 extra lines I do not need. Is there any way I can get these removed from the output? Regards,

how to send certificate authentication in python post request, for example I used next but in get request: requests.get(url, params = params, timeout=60,cert=certs) where certs is path to certificate, it's worked fine. requests.post(url_post,data=params,cert = certs, timeout=60) not working, error - SSL authentication error

To send certificate, you need the certificate which contains public key like server.crt. If you have this crt file then you can send it as r=requests.get('https://server.com', verify='server.crt' ) or if you don't have that file then you can get it using get_ssl_certificate method ert=ssl.get_server_certificate(('server.com',443),ssl_version=3) then you can write it into a file and send it.

I'm working on a unit tests for an API client class. There is a class variable self.session that is supposed to hold the session. In my setup method for my test I create a new instance of the client class and then call its authenticate method. However when the tests themselves go to send requests using this object they all return 401 forbidden errors. If I move the authenticate call (but not the creation of the class) into the tests and out of setup everything works great, but I understand that that defeats the purpose of setup().

An example of the code you're talking about (with proprietary stuff removed, of course), might help clarify. The variable, self.session, is on the test class itself, rather than the instance? That sounds as if it might end up leaking state between your tests. Attaching it to the instance might help. Beyond that, I generally think it makes sense to move as much out of setUp methods as possible. Authentication is part of the important part of your test, and it should probably be done alongside all the other logic.

I'm using python Tornado to perform asynchronous requests to crawl certain websites and one of the things I want to know is if a URL results in a redirect or what it's inital status code is (301, 302, 200, etc.).

The easiest option is probably to convert your XML file either to CSV or to JSON and then load it. Without knowing the size and shape of your data it's hard to make a recommendation, but you can find a variety of converters if you search online for them.

I am currently trying to figure out a way to know who invited a user. From the official docs, I would think that the member class would have an attribute showing who invited them, but it doesn't. I have a very faint idea of a possible method to get the user who invited and that would be to get all invites in the server then get the number of uses, when someone joins the server, it checks to see the invite that has gone up a use. But I don't know if this is the most efficient method or at least the used method.

In Discord, you're never going to 100% sure who invited the user. Using Invite, you know who created the invite. Using on_member_join, you know who joined. So, yes, you could have to check invites and see which invite got revoked. However, you will never know for sure who invited since anyone can paste the same invite link anywhere.

For that specific command, you should not need any automation tool to feed input to your script. Piping a file to it should allow it to execute without user interaction (like Coldspeed said in his comment). Most command line interfaces allow parametrized execution and most parameters you can either build into your script or read them from a config file somewhere. For those command line tools that require "real" user interaction (i.e. you can't pipe the input, parametrize it or somehow build it into the command itself), I used the pexpect module with great success.

"The idea is to create a variety of methods that can be run by clicking a button and/or inserting content in inputs, and having the tests / functions run and returning the specified results." Maybe Flask can help you here. It has a nice functionality to route urls to specific functions or methods in your code. It provides a convenient way to bind actions to code. You can search the web for how you can leverage Flask to cater to your specific needs, but here I just wanted to convey that it would help.

I have a webhook that handles any sms messages sent to my Twilio number. However, this webhook only works if there is text in the message (there will be a body in the GET request).

I solved a similar problem by creating a basic webpage which uses the HTML5 geolocation function to get lat/lng of the phone. It then submits coordinates to a php script via AJAX. My server geocodes the employees location, calculates travelling time to next job and sends the customer an SMS with ETA information using the Twilio API. You could bypass Twilio altogether and get your server to make the request direct to your webhook, or even via the AJAX call if it's all on the same domain. All depends what you are trying to achieve I guess.

Try to connect, and if it fails after n retries, consider you don't have a connection. There are many strategies to setup retries, so search about it to figure what is best for you. Then if you can't connect, just keep going on after the failure... That's about it.

Here's a simple way I'd go about doing it: Create a backend service that exposes the python script's output via HTTP. You can use any familiar backend programming language: python, java, .net etc to host a simple http web server, and expose the data. Create a simple html page, that makes an ajax call to your backend service, pulls the data, and shows it on the page. Later add your buttons, make the page nicer, responsive on other devices.

You can directly answer HTTP requests to pages different to that specific webpage with HTTP redirections (e.g. HTTP 302). Moreover, you should only route packets going to the desired webpage and block the rest (you can do so with a firewall such as iptables).

I need to use selenium for a scraping job with a heap javascript generated webpages. I can open several instances of the webdriver at a time and pass the websites to the instances using queue. It can be done in multiple way.s though. I've experimented with both the Threading module and the Pool- and Process-ways from the multiprocessing module. All work and will do the job quite fast. This leaves me wondering: Which module is generalky prefered in a situation like this?

The main factor in CPython for choosing between Threads of Processes is based on your type of workload. If you have a I/O bound type of workload, where most of your application time is spent waiting for data to come in or to go out, then your best choice is using Threads. If, instead, your application is spending great time using the CPU, then Processes are your tool of choice. This is due to the fact that, in CPython (the most commonly used interpreter) only one Thread at a time can make use of the CPU cores. For more information regarding this limitation just read about the Global Interpreter Lock (GIL). There is another advantage when using Processes which is usually overlooked: Processes allow to achieve a greater degree of isolation. This means that if you have some unstable code (in your case could be the scraping logic) which might hang or crash badly, encapsulating it in a separate Process allows your service to detect the anomaly and recover (kill the Process and restart it).

I couldn't find any API to configure my codeship project :( I have multiple repositories, and would like to allow the following steps programatically: List repositories of my team create a new repo pipeline (for each microservice I have a seperate repo) Edit pipeline steps scripts for newly created project (and for multiple projects "at once") Customize a project's environment variables delete an existing project Is there any way to do it? How do I authenticate? Even if I have to do by recording network curls - is there a better way to authenticate other than pasting an existing cookie I copy from my own browsing?

You have 3 options: implicitly_wait: Implicitly wait means that the it will wait for a maximum of x seconds to search for an element so if you element will appear after 4 seconds you will get it when it will appear second if you set the implicitly wait greater than 4seconds. Use driver.implicitly_wait(x) after creating the instance. explicitly_wait: Explicitly wait means the it will wait for x seconds and it will search for the element after the seconds passed so if you set 10 seconds and the element will appear after 4 seconds the element will be located with 6 seconds delay. Use driver.explicitly_wait(x) after creating the instance time.sleep You can put your program to sleep and wait for the page to fully load after submitting some actions. Use time.sleep(x) after submitting a form, clicking a button or loading a page.

This is a common problem with PhantomJS (the page not being fully rendered), and often isn't something that can be remedied with explicit/implicit waits. Add a long (5 second) sleep to your code and take another screenshot. If the page is fully rendered, follow @Alex Lucaci's instructions for adding (ideally) explicit waits. If the page still isn't fully rendered, PhantomJS just wont work for you in this case. Personally, I would advise against using PhantomJS at all, as it is problematic in a myriad of ways, but also because why would you test on a browser that literally no one uses as their actual browser?

I have a large application and I am using Headless Chrome, Selenium and Python to test each module. I want to go through each module and get all the JS console errors produced while inside that specific module. However, since each module is inside a different test case and each case executes in a separate session, the script first has to login on every test. The login process itself produces a number of errors that show up in the console. When testing each module I don't want the unrelated login errors to appear in the log. Basically, clear anything that is in the logs right now -> go to the module and do something -> get logs that have been added to the console. Is this not possible? I tried doing driver.execute_script("console.clear()") but the messages in the console were not removed and the login-related messages were still showing after doing something and printing the logs.

This thread is a few years old, but in case anyone else finds themselves here trying to solve a similar problem: I also tried using driver.execute_script('console.clear()') to clear the console log between my login process and the page I wanted to check to no avail. It turns out that calling driver.get_log('browser') returns the browser log and also clears it. After navigating through pages for which you want to ignore the console logs, you can clear them with something like _ = driver.get_log('browser')

I am a beginner trying to find a way to stream audio on a local server. I have a Python script that creates some binary data from a robot's microphone, and I want to send this data to be displayed on a local Go server I created. I read somewhere that web sockets could be a solution. But what's the simplest way to upload the audio buffers from the Python script? And how would I retrieve this raw binary data so that it can be streamed from the web app? Many many thanks.

false

There is no single "Best" way. If the protocol has to go over ports 80/443 on the open internet, you could use web-sockets. You could also POST base64 encoded chunks of data from python back to your server. If the robot and server are on the same network, you could send UDP packets from the robot to your server. (Usually a missing packet or two on audio is not a problem). Even if you have a web based Go server, you can still fire off a go routine to listen on UDP for incoming packets. If you could be more specific, maybe I or someone else could give a better answer?

There are many things that could happen. You sould check your logs and add them to the question. One thing I am sure in is that you don't use any virtual display, and you don't have a display on AWS. So you should google for "python running selenium headless"

On some chromebooks, like the one I'm using now, there is a Linux(beta) option in the options menu. Alternatively, you can use repl.it instead, although be aware that playing sound and using geocoder will work server-side instead, so the sound will not play, and the ip adress will be in New York.

So I've decided to learn Python and after getting a handle on the basic syntax of the language, decided to write a "practice" program that utilizes various modules. I have a basic curses interface made already, but before I get too far I want to make sure that I can redirect standard input and output over a network connection. In effect, I want to be able to "serve" this curses application over a TCP/IP connection. Is this possible and if so, how can I redirect the input and output of curses over a network socket?

true

45,062,817

This probably won't work well. curses has to know what sort of terminal (or terminal emulator, these days) it's talking to, in order to choose the appropriate control characters for working with it. If you simply redirect stdin/stdout, it's going to have no way of knowing what's at the other end of the connection. The normal way of doing something like this is to leave the program's stdin/stdout alone, and just run it over a remote login. The remote access software (telnet, ssh, or whatever) will take care of identifying the remote terminal type, and letting the program know about it via environment variables.

I'm not entirely sure of the Qpid for python URI syntax but from the ActiveMQ side a destination is addressed directly by using a destination prefix. For a topic the prefix is topic:// and for queue it is queue:// unsurprisingly. In the absence of a prefix the broker defaults the address in question to a Queue type as that is generally the preference. So to fix your issue you need to construct a URI that uses the correct prefix which in your case would be something using topic://some-name and that should get you the results you expect.

You are doing a comprehension that results in a generator. You can probably fix it by doing len([s for s in self.servers]). EDIT: Generator is an object that does not hold elements in memory but you can still loop over them. Since it doesn't create a list from which to ask the length from you can't perform len().

I'm writing this application where the user can perform a web search to obtain some information from a particular website. Everything works well except when I'm connected to the Internet via Proxy (it's a corporate proxy). The thing is, it works sometimes. By sometimes I mean that if it stops working, all I have to do is to use any web browser (Chrome, IE, etc.) to surf the internet and then python's requests start working as before. The error I get is: OSError('Tunnel connection failed: 407 Proxy Authentication Required',) My guess is that some sort of credentials are validated and the proxy tunnel is up again. I tried with the proxies handlers but it remains the same. My doubts are: How do I know if the proxy need authentication, and if so, how to do it without hardcoding the username and password since this application will be used by others? Is there a way to use the Windows default proxy configuration so it will work like the browsers do? What do you think that happens when I surf the internet and then the python requests start working again? I tried with requests and urllib.request Any help is appreciated. Thank you!

My issue is that I can't seem to find the right api call to use if any exists for this purpose. The two closest that I can seem to find are list_access_keys which I can use to find the creation date of the key. And get_access_key_last_used which can give me the day the key was last used. However neither or others I can seem to find give simply the access key age like is shown in the AWS IAM console users view. Does a way exist to get simply the Access key age?

I have existing REST APIs, written using Django Rest Framework and now due to some client requirements I have to expose some of them as SOAP web services. I want to know how to go about writing a wrapper in python so that I can expose some of my REST APIs as SOAP web services. OR should I make SOAP web services separately and reuse code ? I know this is an odd situation but any help would be greatly appreciated.

Lets Discuss both the Approaches and their pros and cons Seperate SOAP Service Reusing Same Code - if you are sure the code changes will not impact the two code flow ,it is good to go. Extension of Features - if you are sure that new feature extension will not impact other parts it is again best to go. Scalablity - if new API are part of same application and you are sure that it will be scalable with more load ,it is again a good option. Extension - if you are sure in future adding more API will not create a mess of code, it is again good to go for. Soap Wrapper Using Python (my favourate and suggested way to go) Seperation of Concern with this you can make sure ,what ever code you write is sperate from main logic and you can easly plug in and plug out new things. Answer for all the above question in case of this is YES. Your Call , Comments and critisicsm are most welcome

I'm building a web scraper that makes multiple requests concurrently. I'm currently using the multiprocessing module to do so, but since it's running on a Digital Ocean droplet, I'm running into processor/memory bottlenecks. Since this is a web scraper and most of the time spent on the script is likely waiting for the network, isn't it more efficient to use threading instead in order to reduce resource usage? Does threading detect a blocking network call and release locks? Is it feasible to intertwine multiprocessing and multithreading?

true

45,314,387

2

Since the multiprocessing module was developed to be largely compatible with the threading model that pre-dates it, you should hopefully not find it too difficult to move to threaded operations in a single process. Any blocking calls (I/O, mostly) will cause the calling thread to be suspended (become non-runnable) and other threads will therefore get chance to use the CPU. While it's possible to use multi-threading in multiple processes, it isn't usual to do so.

I just started using vk api in python and I am looking for a way to get more than 200 videos (possibly by using multiple api calls) for a specific query. To be more specific, each api call to video.search returns the number of videos that the search yields (the same number can be seen when searching from the website). Is there a way to get let's say the next videos in that list? thanks! :-)

false

The answer is to use the 'offset' parameter. I was not aware of it when I asked the question... I was able to get max of about 4K videos but it take more than 20 API calls as some of the results are repeated i.e., if on the first call I got 200 videos on the second API call with offset 200 I am getting a list of 200 videos but some of them already appeared in the previous list. In addition, you don't always get 200 videos. Sometimes you will get less (and still repetitions are possible).

What does the parameter of 1 mean in the listen(1) method of socket. I am using the socket module in python 2.7 and I have created a basic server that I want to connect to multiple clients (all on a local machine) and transmit data between them. I know there a simpler ways of doing this but I want practice for when the clients would not all be on the same machine and may need to retrieve something from the server first so could not bypass it. I was wondering if the 1 in listen referred to the amount of connections the server would make at a single time and if not what it did mean. I really want to understand in detail how parts of the process work so any help would be appreciated.

It defines the length of the backlog queue, which is the number of incoming connections that have been completed by the TCP/IP stack but not yet accepted by the application. It has nothing whatsoever to do with the number of concurrent connections that the server can handle.

I'm playing around writing a simple multi-threaded web crawler. I see a lot of sources talk about web crawlers as obviously parallel because you can start crawling from different URLs, but I never see them discuss how web crawlers handle URLs that they've already seen before. It seems that some sort of global map would be essential to avoid re-crawling the same pages over and over, but how would the critical section be structured? How fine grained can the locks be to maximize performance? I just want to see a good example that's not too dense and not too simplistic.

false

45,405,321

for crawler don't use ConcurrentHashMap, rather use Databse The number of visisted URL's will grow very fast, so it is not a good thing to store them in memory, better use a databese, store the URL and the date it was last crawled, then just check the URL if it already exists in DB or is eligible for refreshing. I use for example a Derby DB in embedded mode, and it works perfectly for my web crawler. I don't advise to use in memory DB like H2, because with the number of crawled pages you eventually will get OutOfMemoryException. You will rather rarely have the case of crawling the same page more than once in the same time, so checking in DB if it was already crawled recently is enough to not waste significant resources on "re-crawling the same pages over and over". I belive this is "a good solution that's not too dense and not too simplistic" Also, using Databse with the "last visit date" for url, you can stop and continue the work when you want, with ConcurrentHashMap you will loose all the results when app exit. You can use "last visit date" for url to determine if it needs recrawling or not.

Specific domain use case : Use in memory If it is specific domain say abc.com then it is better to have vistedURL set or Concurrent hash map in memory, in memory will be faster to check visited status, memory consumption will be comparatively less. DB will have IO overhead and it is costly and visited status check will be very frequent. It will hit your performance drastically. As per your use case, you can use in memory or DB. My use case was specific to domain where visited URL will not be again visited so I used Concurrent hash map.

It very much depends on the method of authentication used. If it's HTTP Basic Auth, then you should be able to pass those headers along with the request. If it's using a web page-based login, you'll need to automate that request and pass back the cookies or whatever session token is used with the next request.

SSLv3 is considered insecure and should no longer be used. Because of this many current installation of OpenSSL come without support for SSLv3, i.e. it is not compiled into the library. In this case you get the error about unsupported method if you try to explicitly use it and you get a similar error if the SSL handshake fails because the peer tries to use this locally unsupported TLS version. Is there any way to fix that? Don't try to enforce use of SSLv3. Instead use the sane and secure default protocol setting.

I use read_edgelist function of networkx to read a graph's edges from a file(500Mb), G(nodes= 2.3M, edges=33M), it uses the whole memory of machine and seems nothing it does after not finding more memory to load whole graph. Is there any way to handle this problem like sparse graph solution or using other libraries?

false

45,464,760

NetworkX uses a sparse representation; and read_edgelist reads the file line by line (ie. it does not load the whole file at once). So if NetworkX uses too much memory, it means this is actually what it takes to represent the whole graph in memory. A possible solution is to read the file yourself and discard as much edges as possible before feeding it to NetworkX.

I have a pretty much of an idea what you are trying to do with your code. The error you are getting is not neither from the python module nor it's an OS error - it says that the website does not use CA certificates which requests module use to request and fetch data The requests modules fails to make successful handshake - it can be possible that you are not allowed to access that website or the website has its own custom security and bots that not working Fortunately you can create connection pools (proxies) or use httpadapters. requests module can also be used to verify certificates so you can try a bunch of things to make it work.

In my Django application, I call an external API, which returns XML. I would like to display this "minified" response as an indented multiline string on the page (a plus would be syntax highlighting). I tried to process the string in Python with toprettyxml() from xml.dom.minidom, and a few things with ElementTree, but it does not play along the Jinja2 rendering well (line breaks disappear and I only get a one line string, displayed inside <pre> tags). What's the recommended way to display such code excerpt? Should I use client-side rendering? Then, which library should I use? Django version: 1.11.2 Python 3.6.1

ZeroMQ provides feature-rich tools, all the rest above is Designer's job: Given the task description above, the possible approach is to create an application-level logic ( a distributed Finite State Automaton ( dFSA ) with certain depth of process-state memory ), where task-phases' processors report ( guess how -- again by a parallel ZeroMQ signalling / messaging dFSA infrastructure ) achieving ( { enter- | exit- }-triggered state-change ) any of the recognised states and the dFSA logic will thus on the global scale permit to orchestrate and operate the above requested "side"-steps, "branches" and/or "re-submit"-s and similar créme a'la créme tricks. Each ( free )-worker simply always notifies the dFSA-infrastructure it's ( task-unit )-exit-triggered state-change and your dFSA-infrastructure thus always knows + does not search ad-hoc for an address of any such worker, as it explicitly continuously keeps records on free-state dFSA-nodes ( to pick from ). Re-discovery, watch-dogs, heart-beats and re-confirmation handshaking schemes are also possible within the dFSA-infrastructure signalling. That simple.

I have a python file that is taking websocket data and constantly updating a giant list. It updates somewhere between 2 to 10 times a second. This file runs constantly. I want to be able to call that list from a different file so this file can process that data and do something else with it. Basically file 1 is a worker that keeps the current state in a list, I need to be able to get this state from file 2. I have 2 questions: Is there any way of doing this easily? I guess the most obvious answers are storing the list in a file or a DB, which leads me to my second question; Given that the list is updating somewhere between 2 and 10 times a second, which would be better? a file or a db? can these IO functions handle these types of update speeds?

DB is the best bet for your use case This gives the flexibility to know which part of data you have already processed by having a status flag. Persistence data (you can also have data replication) You can scale easily if in future your applications pulls more and more data 2 -10 times is a good use case for heavy write application with DB as you will gather tons of data in short duration.

"User clicks ad -> opens up a website to get the pixel conversion hit -> immediate re-direct back to messenger" I don't see how this is helping, as the pixel conversion hit happens before any action happens within the chat. If you want to track a certain action within the chat, couldn't you redirect to a website and re-direct back to the chat from within the chat, say in the middle of the question flow?

Try a web server like flask that forwards requests to the celery workers. Or try a server that reads from a queue (SQS, AMQP,...) and does the same. No matter the solution you choose, you end up with 2 services: the celery worker itself and the "server" that calls the celery tasks. They both share the same code but are launched with different command lines. Alternately, if the task code is small enough, you could just import the git repository in your code and call it from there

I don't see any "wrong" IPs in your question. A DNS server is allowed to return multiple IP addresses for the same host. The client generally just picks one of them. A lot of servers use this as a part of their load balancing, as clients select any available server and since they generally would pick different ones the traffic gets split up evenly. Your ping command and your gethostbyname command are just selecting different available IPs, but neither is "wrong". You can see all the IPs that are returned for a given hostname with a tool like nslookup or dig.

I am working on a web based application where users will use their webcams for realtime Video call on web browser (kinda Webx). Is their any way that the web application can identify if any (tcp/udp/https) application/service is using the video service and consuming the network bandwidth so that I can show a message to the user - "Please close skype or gtalk and then to proceed with the video call". In short; how to identify skype like service which is holding the webcam via web application and alert user to close that app first.

Your web application can not know if there is a video service like Skype that is running on the same host than the browser, but your application can simply run a speed test, to check for the currently available bandwidth between the browser and your server. For instance, you can do that easily writing some AJAX code that automatically starts downloading a big file (using XMLHttpRequest()) and stops after 10 seconds (using XMLHttpRequest.abort()). You can monitor the throughput using progress events. Then, if your app find that there is not enough bandwidth, you may ask the user to stop network applications.
