0 | 0 | I started writing some python code that adds events to a spreadsheet in Google Sheets using gdata. Everything went well and it works, but now I wanted to add these same events to a calendar and I can't figure out what I'm supposed to use.
I see that the calendar API on Google is at V3 and they suggest I install google-api-python-client. Gdata seems to be almost abandoned and I feel like I'm lost in the middle.
I would just like to be able to use one python API to add data to a calendar and a spreadsheet and if possible keeping things simple as I'm really not very good at this yet. Any help would be greatly appreciated.

0 | 0 | I came across the term "Opinionated API" when reading about the ssl.create_default_context() function introduced by Python 3.4, what does it mean? What's the style of such API? Why do we call it an "opinionated one"?
Thanks a lot. | true | 28,535,671 | 1.2 | 0 | 0 | 17 | It means that the creator of the API makes some choices for you that are in her opinion the best.
For example, a web application framework could choose to work best with (or even bundle or work exclusively with) a selection of lower-level libraries (for stuff like logging, database access, session management) instead of letting you choose (and then have to configure) your own.
In the case of ssl.create_default_context some security experts have thought about reasonably secure defaults to configure SSL connections. In particular, it limits the available algorithms to those that are still considered secure, at the expense of complete compatibility with legacy systems, a trade-off that is beneficial in their (and my) opinion.
Essentially they are saying "we have a lot of experience in this domain, and we really think you should do things in the following way".
I suppose this is a response to "enterprise" API that claim to work with every implementation of as many standard interfaces as possible (at the expense of complexity in configuration and combination, requiring costly consultants to set up everything).
Or a natural extension of "Convention over Configuration".
Things should work very well out-of-the-box, so that you only have to twiddle around with expert settings in special cases (and by then you should know what you are doing), as opposed to even a beginner having to make informed decisions about every aspect of the application (which can end in disaster). | 1 | 2,047 | 0 | 8 | 2015-02-16T06:27:00.000 | api,python-3.x | What does "Opinionated API" mean? | 1 | 1 | 1 | 28,535,731 | 0 |
0 | 0 | Which is the best method for sending a data using sockets:
Method 1: Creating a new socket every time when data needs to be sent and closing it when the transfer is complete.
Method 2: Using the same socket instead of creating a new socket and maintaining the connection even when waiting for new data. | false | 28,541,889 | 0.197375 | 0 | 0 | 2 | That depends. Creating a new socket means two computers have to discover each other, so there is name lookup, TCP/IP routing and resource allocation involved. Not really cheap but not that expensive either. Unless you send data more than 10 times/second, you won't notice.
If you keep a socket open and don't send data for some time, a firewall between the two computers will eventually decide that this connection is stale and forget about it. The next data packet you send will fail with a timeout.
So the main difference between the two methods is whether you can handle the timeout case properly in your code. You will have to handle this every time you write data to the socket.
In many cases, the code to write is hidden very deep somewhere and the code doesn't actually know that it's writing to a socket plus you will have more than one place where you write data, so the error handling will leak into your design. That's why most people prefer to create a new socket every time, even if it's somewhat expensive. | 0 | 2,330 | 0 | 4 | 2015-02-16T12:55:00.000 | python,sockets,networking | Which is a larger overhead: Creating a new socket each time or maintaining a single socket for data transfer | 1 | 2 | 2 | 28,542,041 | 0 |
0 | 0 | Which is the best method for sending a data using sockets:
Method 1: Creating a new socket every time when data needs to be sent and closing it when the transfer is complete.
Method 2: Using the same socket instead of creating a new socket and maintaining the connection even when waiting for new data. | true | 28,541,889 | 1.2 | 0 | 0 | 5 | It depends on the kind of socket, but in the usual cases it is better to keep the socket unless you have very limited resources.
UDP is connectionless, that is you create the socket and there is no delay because of connection setup when sending a packet. But there are still system calls involved and allocating memory etc, so it is cheap but not free.
TCP instead needs to establish the connection before you can even start to sending data. How fast this is done depends on the latency, i.e. fast on local machine, slower in local network and even slower on the internet. Also, connection start slowly because the available bandwidth is not known yet.
With SSL/TLS on top of TCP connection setup is even more expensive because it needs more round trips between client and server.
In summary: If you are using TCP you almost always better keep the socket open and close it only if you lack the necessary resources to keep it open. A good compromise is to close the socket as long as you have enough activity on the socket. This is the approach usually done with HTTP persistent connections. | 0 | 2,330 | 0 | 4 | 2015-02-16T12:55:00.000 | python,sockets,networking | Which is a larger overhead: Creating a new socket each time or maintaining a single socket for data transfer | 1 | 2 | 2 | 28,543,387 | 0 |

0 | 0 | I need to constantly access a server to get real time data of financial instruments. The price is constantly changing so I need to request new prices every 0.5 seconds. The REST APIs of the brokers let me do this, however, I have noticed there's quite some delay when connecting to the server. I just noticed that they also have websocket API though. According to what I read, they both have some pros/cons. But for what I want to do and because speed is specially important here, which kind if API would you recommend? Is websocket really faster?
Thank you! | true | 28,613,399 | 1.2 | 0 | 0 | 84 | The most efficient operation for what you're describing would be to use a webSocket connection between client and server and have the server send updated price information directly to the client over the webSocket ONLY when the price changes by some meaningful amount or when some minimum amount of time has elapsed and the price has changed.
This could be much more efficient than having the client constantly ask for new price changes and the timing of when the new information gets to the client can be more timely.
So, if you're interested in how quickly the information on a new price level gets to the client, a webSocket can get it there much more timely because the server can just send the new pricing information directly to the client the very moment it changes on the server. Whereas using a REST call, the client has to poll on some fixed time interval and will only ever get new data at the point of their polling interval.
A webSocket can also be faster and easier on your networking infrastructure simply because fewer network operations are involved to simply send a packet over an already open webSocket connection versus creating a new connection for each REST/Ajax call, sending new data, then closing the connection. How much of a difference/improvement this makes in your particular application would be something you'd have to measure to really know.
But, webSockets were designed to help with your specific scenario where a client wants to know (as close to real-time as practical) when something changes on the server so I would definitely think that it would be the preferred design pattern for this type of use.
Here's a comparison of the networking operations involved in sending a price change over an already open webSocket vs. making a REST call.
webSocket
Server sees that a price has changed and immediately sends a message to each client.
Client receives the message about new price.
Rest/Ajax
Client sets up a polling interval
Upon next polling interval trigger, client creates socket connection to server
Server receives request to open new socket
When connection is made with the server, client sends request for new pricing info to server
Server receives request for new pricing info and sends reply with new data (if any).
Client receives new pricing data
Client closes socket
Server receives socket close
As you can see there's a lot more going on in the Rest/Ajax call from a networking point of view because a new connection has to be established for every new call whereas the webSocket uses an already open call. In addition, in the webSocket cases, the server just sends the client new data when new data is available - the client doens't have to regularly request it.
If the pricing information doesn't change super often, the REST/Ajax scenario will also frequently have "do-nothing" calls where the client requests an update, but there is no new data. The webSocket case never has that wasteful case since the server just sends new data when it is available. | 0 | 21,513 | 0 | 40 | 2015-02-19T17:51:00.000 | python,rest,websocket,httprequest | websocket vs rest API for real time data? | 1 | 1 | 1 | 28,618,369 | 0 |

1 | 0 | I'm planning to deliver an API as a web-service. When I update my API's (interpreted) code-base, however, I anticipate possibly needing to restart the API service or even just have a period where the code is being overwritten. This introduces the possibility that incoming API requests may be dropped or, even worse, that processes triggered by the API may be interrupted.
The flask library for python appears to offer something of a solution; by enabling debug mode it will check the modified flag on all python files and, for each request, it will reload any modules that have changed. It's not the performance penalty that puts me off this approach - it's the idea that it looks slightly jilted.
Surely there is an elegant, high-availability approach to what must be a common issue?
Edit: As @piotrek answered below, "there is no silver bullet". One briefly visible comment suggested using DNS to switch to a new API server after an update. | true | 28,625,474 | 1.2 | 0 | 0 | 1 | actually there is no silver bullet. you mention two different things. one is availability. it depends on how many nines you want to have in your 9,999... availability. second thing is api change. so:
availability:
some technologies allows you to do hot changes/deloyments. which means pending requests goes the old path, new request goes the new path. if your technology don't support it you can't use it for othe reasons, there are other options
in small scale intranet applications you simply don't care. you stop the world: stop the application, upload new version and start. on application stop many web frameworks stop accepting new connection and wait until all pending requests are finished. if yours don't support it you have 2 options:
ignore it (db will rollback current transaction, user will get error)
implement it yourself (may be challenging).
and you do your best to shorten the inactivity period.
if you can't afford to stop everything then you can do:
clustering. restart one service by one. all the time some server is available. that's not always possible because sometimes you have to change your database and not always you can do it on working system or you can't afford to loose any data in case of update failure
microservices. if you split your application into many independent components connected with persistent queues then you turn of only some parts of your system (graceful degradation). for example you can disable component that writes changes to the database but still allow reads. if you have infrastructure to do it quickly then the update may be unnoticed - requests will be put into queues and picked up by new version
api change:
you version your api. each request says which version it requires.
if you control all your clients / small scale / decide not to support old versions : you don't care. everyone has to update its client.
if not, then again microservices may help. you split your public api from internal api. and you keep all your public api services running and announce then some of them are deprecated. you monitor their usage. when you decide that usage of some version is low enough you announce end-of-life and later you shutdown specific version

1 | 0 | The boto config has a num_retries parameter for uploads.
num_retries
The number of times to retry failed requests to an AWS server. If boto
receives an error from AWS, it will attempt to recover and retry the
request. The default number of retries is 5 but you can change the
default with this option.
My understanding is that this parameter governs how many times to retry on commands like set_content_from_string. According to the documentation, the same command will fail if the md5 checksum does not match upon upload. My question is, will boto also retry upon checksum failure, or does num_retry apply to a separate class of failures? | true | 28,732,751 | 1.2 | 0 | 0 | 1 | When boto uploads a file to S3 it calculates the MD5 checksum locally, sends that checksum to S3 as the Content-MD5 header and then checks the value of the ETag header returned by the S3 service against the previously computed MD5 checksum. If the ETag header does not match the MD5 it raises an S3DataError exception. This exception is a subclass of ClientError and client errors are not retried by boto.
It is also possible for the S3 service to return a BadDigest error if the Content-MD5 header we provide does not match the MD5 checksum computed by the service. This is a 400 response from S3 and is also considered a client error and would not be retried. | 0 | 329 | 0 | 1 | 2015-02-26T01:06:00.000 | python,amazon-s3,boto | Does Boto retry on failed md5 checks? | 1 | 1 | 1 | 28,745,850 | 0 |

I came up with a reason, the website is using Javascript to populate the values in their corresponding fields from its own database. If so then how can i fetch them using Python? | false | 28,765,398 | 0 | 0 | 0 | 0 | Yes, you can scrape JS data, it just takes a bit more hacking. Anything a browser can do, python can do.
If you're using firebug, look at the network tab to see from which particular request your data is coming from. In chrome element inspection, you can find this information in a tab named network, too. Just hit ctrl-F to search the response content of the requests.
If you found the right request, the data might be embedded in JS code, in which case you'll have some regex parsing to do. If you're lucky, the format is xml or json, in which case you can just use the associated builtin parser. | 0 | 272 | 0 | 0 | 2015-02-27T12:42:00.000 | javascript,python,html,web-scraping,beautifulsoup | How to fetch data from a website using Python that is being populated by Javascript? | 1 | 2 | 2 | 28,850,142 | 0 |

0 | 0 | I am running some application in multiple network namespace. And I need to create socket connection to the loopback address + a specific port in each of the name space. Note that the "specific port" is the same across all network namespaces. Is there a way I can create a socket connection like this in python?
Appreciate any pointer! | false | 28,846,059 | 0 | 0 | 0 | 0 | I just came across this post while looking into network namespaces and using python to interact with them. In regards to your question about non-root users running the setns(), or similar functions, I believe that is achievable. In a small script that creates the red and blue namespaces mentioned in this post, you could also set a linux capability inside of the new namespace that would allow non-root users to attach and bind. Directly from the man page, we see this description: call setns(2) (requires CAP_SYS_ADMIN in the target namespace);
Capabilities can be added to binaries such as the python2.7 or it can also be added to systemd processes. For example, if you look at the default openvpn-server service file on a centos 7 or RHEL 7 you can see added capabilities so that it can run without root privileges: CapabilityBoundingSet=CAP_IPC_LOCK CAP_NET_ADMIN.....
I know this isn't an answer to the original question, but I do not have enough reputation to reply to comments at the moment. I would suggest looking at capabilities and all of the options provided if you are security conscious and looking to run code as non-root users. | 0 | 6,844 | 0 | 8 | 2015-03-04T03:12:00.000 | python,sockets,namespaces | Can I open sockets in multiple network namespaces from my Python code? | 1 | 1 | 2 | 67,091,745 | 0 |

I think you could possibly use two queues (or more generally N queues where N is the number of levels of priority) but even this seems impossible if you don't actually have the message object at the time you determine that it has failed. You would need the message object so that the data could be written to the high-priority queue.

1 | 0 | I wrote a script that scrapes various things from around the web and stores them in a python list and have a few questions about the best way to get it into a HTML table to display on a web page.
First off should my data be in a list? It will at most be a 25 by 9 list.
I’m assuming I should write the list to a file for the web site to import? Is a text file preferred or something like a CSV, XML file?
Whats the standard way to import a file into a table? In my quick look around the web I didn’t see an obvious answer (Major web design beginner). Is Javascript this best thing to use? Or can python write out something that can easily be read by HTML?
Thanks | true | 28,972,157 | 1.2 | 0 | 0 | 2 | store everything in a database eg: sqlite,mysql,mongodb,redis ...
then query the db every time you want to display the data.
this is good for changing it later from multiple sources.
store everything in a "flat file": sqlite,xml,json,msgpack
again, open and read the file whenever you want to use the data.
or read it in completly on startup
simple and often fast enough.
generate a html file from your list with a template engine eg jinja, save it as html file.
good for simple hosters
There are some good python webframeworks out there some i used:
Flask, Bottle, Django, Twisted, Tornado
They all more or less output html.
Feel free to use HTML5/DHTML/Java Script.
You could use a webframework to create/use an "api" on the backend, which serves json or xml.

0 | 0 | I have a python script that scans for new tweets containing specified #hashtags, then it posts them to my "python bot's" twitter account as new tweets.
I tested it from the python console and let it run for 5 minutes. It managed to pick up 10 tweets matching my criteria. It works flawlessly, but I'm concerned about performance issues and leaving the script running for extended amounts of time.
What are the negative effects of leaving this script running on my personal computer for a whole day or more?
Should I be running this on a digital ocean VPS instead?
Twitter offers the API for bot creation, but do they care how much a bot tweets? I don't see how this is any different from retweeting. | true | 28,974,896 | 1.2 | 1 | 0 | 1 | Twitter probably has limits on their api and will most likely block your api key if they feel that you are spamming. In fact I would bet there is a maximum number of tweets per day depending on the type of developer account.
For stability and up time concerns running on a 'personal' computer is not a good idea. You probably want to do other things on your personal comp that may interrupt your bot's service (like install programs/updates and restart). As far as load on the cpu, well if its only picking up 10 tweets per 5 min that doesn't seem like any kind of load that you need to worry about. To be sure you could run the top command and check out the cpu and memory usage.
If you have a server somewhere like at digital ocean then I would run it there just to reduce the interruption the program experiences.
I ran a similar program using twitters stream api and collected tweets using a personal computer and the interruptions were annoying and I eventually stopped collecting data.... | 0 | 399 | 0 | 0 | 2015-03-10T22:00:00.000 | python,twitter,tweepy | Running python tweepy listener | 1 | 1 | 1 | 28,977,051 | 0 |
0 | 0 | Openstack-Swift is using evenlet.green.httplib for BufferedHttpconnections.
When I do performance benchmark of it for write operations, I could observer that write throughput drops even only one replica node is overloaded.
As I know write quorum is 2 out of 3 replicas, therefore overloading only one replica cannot affect for the throughput.
When I dig deeper what I observed was, the consequent requests are blocked until the responses are reached for the previous requests. Its mainly because of the BufferedHttpConnection which stops issuing new request until the previous response is read.
Why Openstack-swift use such a method?
Is this the usual behaviour of evenlet.green.httplib.HttpConnection?
This does not make sense in write quorum point of view, because its like waiting for all the responses not a quorum.

it does not block.

0 | 0 | I recently started searching for socket programming, and decided to use python for testing. I have the following question: As I read, you can only listen for a limited number of connections in a server-side socket, thus you can only have such a number of connections operating at a time. Is there a way to be able to hold as many sockets open as the system can tolerate? That is e.g. in the case of a chat server (you would not want to only have 5 active users at a time, for example).
What's the solution to that? Should one create more sockets to achieve that goal? But then, would the number of ports available to the system be the next limitation? | true | 29,149,000 | 1.2 | 0 | 0 | 0 | If you are asking about function 'listen':
'backlog' argument is the maximum length to which the queue of pending connections for socket may grow.
If a connection request arrives when the queue is full, the client may receive an error with an indication of ECONNREFUSED or, if the underlying protocol supports retransmission, the request may be ignored so that a later reattempt at connection succeeds.
This does not set any limit on number of socket connections. Only the ones which were not 'accept'-ed yet (e.g. have not become 'connection').
When client tries to connect the backlog grows by 1.
When you call 'accept' the backlog decreases by 1.
So if you will call 'accept' periodically you will open a number of connections. | 0 | 103 | 0 | 0 | 2015-03-19T15:42:00.000 | python,sockets,server-side | Arbitrarily large number of sockets - Python | 1 | 1 | 1 | 29,149,290 | 0 |

0 | 0 | Many search engines track clicked URLs by adding the result's URL to the query string which can take a format like: http://www.example.com/result?track=http://www.stackoverflow.com/questions/ask
In the above example the result URL is part of the query string but in some cases it takes the form http://www.example.com/http://www.stackoverflow.com/questions/ask or URL encoding is used.
The approach I tried first is to split searchengineurl.split("http://"). Some obvious problems with this:
it would return all parts of the query string that follow the result URL and not just the result URL. This would be a problem with an URL like this: http://www.example.com/result?track=http://www.stackoverflow.com/questions/ask&showauthor=False&display=None

Release notes from seleniumhq.org. Note that we have to use version 2.46 for the jar, iedriverserver.exe and python client driver in order to have things work correctly. It is unclear why 2.45 does not work given the release notes below.
v2.45.0.2
Updates to JavaScript automation atoms.
Added pageLoadStrategy to IE driver. Setting a capability named
pageLoadStrategy when creating a session with the IE driver will now change
the wait behavior when navigating to a new page. The valid values are:
"normal" - Waits for document.readyState to be 'complete'. This is the
default, and is the same behavior as all previous versions of
the IE driver.
"eager" - Will abort the wait when document.readyState is
'interactive' instead of waiting for 'complete'.
"none" - Will abort the wait immediately, without waiting for any of
the page to load.
Setting the capability to an invalid value will result in use of the
"normal" page load strategy. | 0 | 2,136 | 0 | 0 | 2015-03-24T19:35:00.000 | python,selenium,selenium-webdriver,webdriver,internet-explorer-11 | IE11 stuck at initial start page for webdriver server only when connection to the URL is slow | 1 | 2 | 3 | 39,231,646 | 0 |

If you can't join the scripts for some reason, create a unix-domain socket to pass the raw, binary data directly from one to the other. These fifos have limited size so you'll still have to do in-memory buffering on one side or another, probably the B side.
If the data is too big for memory, you can write it out to a temporary file and re-read it when it's time to pass it on.

0 | 0 | I am doing my bachelor's thesis where I wrote a program that is distributed over many servers and exchaning messages via IPv6 multicast and unicast. The network usage is relatively high but I think it is not too high when I have 15 servers in my test where there are 2 requests every second that are going like that:
Server 1 requests information from server 3-15 via multicast. every of 3-15 must respond. if one response is missing after 0.5 sec, the multicast is resent, but only the missing servers must respond (so in most cases this is only one server)
Server 2 does exactly the same. If there are missing results after 5 retries the missing servers are marked as dead and the change is synced with the other server (1/2)
So there are 2 multicasts every second and 26 unicasts every second. I think this should not be too much?
Server 1 and 2 are running python web servers which I use to do the request every second on each server (via a web client)
The whole szenario is running in a mininet environment which is running in a virtual box ubuntu that has 2 cores (max 2.8ghz) and 1GB RAM. While running the test, i see via htop that the CPUs are at 100% while the RAM is at 50%. So the CPU is the bottleneck here.
I noticed that after 2-5 minutes (1 minute = 60 * (2+26) messages = 1680 messages) there are too many missing results causing too many sending repetitions while new requests are already coming in, so that the "management server" thinks the client servers (3-15) are down and deregisters them. After syncing this with the other management server, all client servers are marked as dead on both management servers which is not true...
I am wondering if the problem could be my debug outputs? I am printing 3-5 messages for every message that is sent and received. So that are about (let's guess it are 5 messages per sent/recvd msg) (26 + 2)*5 = 140 lines that are printed on the console.
I use python 2.6 for the servers.
So the question here is: Can the console output slow down the whole system that simple requests take more than 0.5 seconds to complete 5 times in a row? The request processing is simple in my test. No complex calculations or something like that. basically it is something like "return request_param in ["bla", "blaaaa", ...] (small list of 5 items)"
If yes, how can I disable the output completely without having to comment out every print statement? Or is there even the possibility to output only lines that contain "Error" or "Warning"? (not via grep, because when grep becomes active all the prints already have finished... I mean directly in python)
What else could cause my application to be that slow? I know this is a very generic question, but maybe someone already has some experience with mininet and network applications... | false | 29,461,480 | 0 | 1 | 0 | 0 | I finally found the real problem. It was not because of the prints (removing them improved performance a bit, but not significantly) but because of a thread that was using a shared lock. This lock was shared over multiple CPU cores causing the whole thing being very slow.
It even got slower the more cores I added to the executing VM which was very strange...
Now the new bottleneck seems to be the APScheduler... I always get messages like "event missed" because there is too much load on the scheduler. So that's the next thing to speed up... :) | 1 | 102 | 0 | 0 | 2015-04-05T19:44:00.000 | python,performance,networking,cpu,mininet | Console output consuming much CPU?

If you are using a third party firewall - uninstall it and use Windows firewall. The main offender here is Avast/AVG. If you really want to you can set such software to "ask" you for rule creation, AVG ignores these rules in this case and blocks what it thinks is an external "Tcp/Udp" (sic) public connection.
Using Process Explorer from SysInternals reveals the succesful connection between the two processes. AVG cannot seem to deal with "phone home" situation originating on the same host. The problem should be more widespread as many debuggers operate in the same way, so there may be some contribution to this problem by the IDLE developers.

The problem is because of a network socket timeout on the IPC pipes between the RPC subprocess.
It's a poor design (insecure and prone to failure) that's commonly used for IPC instead of process pipes.
The fix is to clear out some RAM and CPU usage and wait a minute before trying again.
And for developers, the fix is to stop using sockets for IPC and use proper process pipes.
Yes, it's the same exact socket timeout issue you experience with your browser, though on modern browsers, the page just stops loading instead of displaying a timeout error screen.

Thank you on your time :D | false | 29,567,051 | 0.049958 | 0 | 0 | 3 | Simple...rename your .py file with some name different from any keyword name like 'random.py' which already exists in python package.
Eg. I named one file as "random.py". The same error popped up. I renamed it to "random_demo.py". It worked.
The different naming discards the problem of ambiguity between an already existing file and a newly created file with same name. | 0 | 111,264 | 0 | 20 | 2015-04-10T17:10:00.000 | python,user-interface,runtime-error,subprocess,python-idle | Python error - IDLE's subprocess didn't make connection.

1 | 0 | I am busy developing a Python system that uses web-sockets to send/received data from a serial port.
For this to work I need to react to data from the serial port as it is received. Problem is to detect incoming data the serial port needs to queried continuously looking for incoming data. Most likely a continuous loop. From previous experiences(Slow disk access + heavy traffic) using Flask this sounds like it could cause the web-sockets to be blocked. Will this be the case or is there a work around?
I have looked at how NodeJS interact with serial ports and it seems much nicer. It raises an event when there is incoming data instead of querying it all the time. Is this an option in Python?
Extra Details:
For now it will only be run on Linux.(Raspbian)

0 | 0 | I need to write python script which performs several tasks:
read commands from console and send to server over tcp/ip
receive server response, process and make output to console.
What is the best way to create such a script? Do I have to create separate thread to listen to server response, while interacting with user in main thread? Are there any good examples? | false | 29,694,344 | 0.197375 | 0 | 0 | 1 | Calling for a best way or code examples is rather off topic, but this is too long to be a comment.
There are three general ways to build those terminal emulator like applications :
multiple processes - the way the good old Unix cu worked with a fork
multiple threads - a variant from the above using light way threads instad of processes
using select system call with multiplexed io.
Generally, the 2 first methods are considered more straightforward to code with one thread (or process) processing upward communication while the other processes the downward one. And the third while being trickier to code is generally considered as more efficient
As Python supports multithreading, multiprocessing and select call, you can choose any method, with a slight preference for multithreading over multiprocessing because threads are lighter than processes and I cannot see a reason to use processes.
Following in just my opinion
Unless if you are writing a model for rewriting it later in a lower level language, I assume that performance is not the key issue, and my advice would be to use threads here. | 0 | 78 | 1 | 0 | 2015-04-17T08:41:00.000 | python,multithreading,tcpclient | Whats the best way to implement python TCP client? | 1 | 1 | 1 | 29,695,958 | 0 |
1 | 0 | I am currently working on a HTML presentation, that works well, but I need the presentation to be followed simultaneously with a NAO robot who reads a special html tag. I somehow need to let him know, which slide I am on, so that he can choose the correct tag.

The problem is, there is javascript running behind, assigning various classes to specific slides, that tell the current state of the presentation.

I've tried several browsers including Chrome and Firefox. I am on a MAC if that matters.

0 | 0 | I want to parse a large XML file (25 GB) in python, and change some of its elements.
I tried ElementTree from xml.etree but it takes too much time at the first step (ElementTree.parse).
I read somewhere that SAX is fast and do not load the entire file into the memory but it just for parsing not modifying.
'iterparse' should also be just for parsing not modifying.
Is there any other option which is fast and memory efficient? | true | 29,853,949 | 1.2 | 0 | 0 | 2 | What is important for you here is that you need a streaming parser, which is what sax is. (There is a built in sax implementation in python and lxml provides one.) The problem is that since you are trying to modify the xml file, you will have to rewrite the xml file as you read it.
An XML file is a text file, You can't go and change some data in the middle of the text file without rewriting the entire text file (unless the data is the exact same size which is unlikely)
You can use SAX to read in each element and register an event to write back each element after it is been read and modified. If your changes are really simple it may be even faster to not even bother with the XML parsing and just match text for what you are looking for.
If you are doing any signinficant work with this large of an XML file, then I would say you shouldn't be using an XML file, you should be using a database.

0 | 0 | Amazon is sunsetting SSLv3 support soon, and I am trying to verify that boto is utilizing TLS. Is there a good way to verify this? Or is there a good test to show TLS utilization? | false | 29,903,119 | 0.291313 | 0 | 0 | 3 | As stated above, you can use a packet sniffer to determine if SSLv3 connections are being made:
# sudo tcpdump -i eth0 'tcp[((tcp[12]>>4)*4)+9:2]=0x0300'
Replace 'eth0' with the correct interface. Then test if it's working, by performing a SSLv3 connection with openssl:
# openssl s_client -connect s3.amazonaws.com:443 -ssl3
That activity should be captured by tcpdump, if network interface is correct. Finally, test your app. If it's using SSLv3 it should be visible as well. You can also change the capture filter to see what protocol is being used:
TLSv1 - 0x0301
TLSv1.1 - 0x0302
TLSv1.2 - 0x0303 | 0 | 3,258 | 0 | 10 | 2015-04-27T18:17:00.000 | python,ssl,amazon-s3,boto,sslv3 | How to tell if boto is using SSLv3 or TLS? | 1 | 2 | 2 | 30,388,720 | 0 |

I named my Python example script bs4.py
Inside this script, whenever trying to import bs4 using the command:
from bs4 import BeautifulSoup, an ImportError was thrown, but confusingly (for me) the import worked perfectly from an interactive shell within the same venv environment.
After renaming the Python script, imports work as expected. The error was caused as Python tries to import itself from the local directory rather than using the system copy of bs4 | 0 | 46,868 | 0 | 18 | 2015-04-27T22:57:00.000 | python,beautifulsoup | Cannot import Beautiful Soup | 1 | 12 | 15 | 52,847,210 | 0 |
