• How do I use python-webkit2png to take many screenshots at the same time?

  - by oldfellow

  I've got thousands of urls from many hosts I need to screenshot. I can use the lib fine from the command line, but how can I integrate it into my code so I can take multiple screenshots simultaneously? I think it's something to do with xvfb as with the answer to this question: http://stackoverflow.com/questions/1747022/how-to-kill-headless-x-server-started-via-python but I'm not sure what exactly.

  - by bobo

  After reading this thread: http://stackoverflow.com/questions/2792932/nsuserdefaults-not-present-on-first-run-on-simulator I know it's quite easy to store some app data in the [NSUserDefaults standardUserDefaults]. But if other applications also happen to use the same key to store their data, is this possible that my app data gets overwritten? Many thanks to you all.

• Flash Browser? Flash Server Side?

  - by Abs

  Hello all, I have two noobish questions about Flash, Actionscript, Flex etc. 1) With these technologies is it possible to create a simple web browser that can render websites? 2) Is it possible to run these technologies on the server side? I am guessing no as Flash requires a browser to run within? Thanks all for any help

• Is there a limit to the size of an application in the Android Marketplace?

  - by Trukdero

  I know from reading this: http://stackoverflow.com/questions/1230457/is-there-a-size-limit-for-ota-android-market-downloads/1232145#1232145 That there wasn't a limit to the size of an application that could be downloaded over the air (OTA) but I wonder if a limit, like that imposed by the Apple App Store (20MB) exists now that the Nexus one is running on AT&T's 3G network as of today. Thanks in advance for your help/ Truk

• Publishing an open source project as a public repository and applying a license

  - by Anton

  If I publish my project now, with added license information, will the license still apply to the project if one goes back a few commits in the history to a state where I hadn't yet added any license information? [Relevant answer][1] [1]: http://stackoverflow.com/questions/2468566/correctly-applying-an-open-source-license/2468663#2468663 Relevant answer This suggests that unless there is some license information available, no rights are granted. Is that true in this case too? Or will the license I added in the last commit also apply to older commits?

• C#, why does Convert.ToBoolean("0") fail?

  - by JL

  I know that trying to convert string "0" to boolean will fail, I also know how to fix this, thanks to Jon Skeets answers on other questions. What I would like to know is WHY does C# not recognise "0" as a valid input for a boolean conversion, surely you could look at it like 0 = false, 1 = true, or even -1 = false and 0 = true, anyways, my logic tells me that it could be a valid input, so is there a very good reason why its not? My bet is old vb6 would be able to recognize the string input "0" as valid.

• matlab: subs on symbolic constant returns scalar instead of vector for a vector input

  - by noam

  usually, symbolic functions return vectors for vector inputs: syms('x'); f=x*2; subs(f,[1 2 3]) outputs: [2 4 6] but doing f=sym('0'); subs(f,[1 2 3]); outputs: 0 and not: [0 0 0] so basically, my questions is how do I make f behave as a "normal" symbolic function. I can do something ugly like f=x-x to create a function that always returns zero, but is there a prettier way?
