• Can't import matplotlib

  - by None

  I installed matplotlib using the Mac disk image installer for MacOS 10.5 and Python 2.5. I installed numpy then tried to import matplotlib but got this error: ImportError: numpy 1.1 or later is required; you have 2.0.0.dev8462. It seems to that version 2.0.0.dev8462 would be later than version 1.1 but I am guessing that matplotlib got confused with the ".dev8462" in the version. Is there any workaround to this?

• Determining when scrolled to bottom of a page with Javascript

  - by chimerical

  I'm trying to determine when I've scrolled to the bottom of the page (without using any JS library), but so far, I'm a bit confused over which one of the following to use. The most promising one I've seen is window.scrollY, but even when scrolled to the bottom of the page, it never matches the value of window.innerHeight. What's the best way to do this? window.innerWidth window.innerHeight window.outerWidth window.outerHeight window.scrollX window.scrollY document.body.scrollWidth document.body.scrollHeight document.body.scrollTop document.body.scrollLeft document.body.offsetTop document.body.offsetLeft document.body.offsetWidth document.body.offsetHeight

• Any way to automatically wrap comments at column 80 in Visual Studio 2008? ..or display where column

  - by Jon Cage

  Is there any way to automatically wrap comments at the 80-column boundary as you type them? ..or failing that, any way to display a faint line at the coulmn 80 boundary to make wrapping them manually a little easier? Several other IDEs I use have one or other of those functions and it makes writing comments that wrap in sensible places much easier/quicker. [Edit] If (like me) you're using Visual C++ Express, you need to change the VisualStudio part of the key into VCExpress - had me confused for a while there!

• TCP/UDP and ethernet MTU Fragmentation

  - by Fantastic Fourier

  I've read various sites and tutorials online but I am still confused. If the message is bigger than IP MTU, then send() returns the byte sent. What happens to the rest of the message? Am I to call send() again and attempt to send rest of the message? Or is that something IP layer should take care of automatically?

• Example compilers

  - by saf

  I'm searching for the source code of a compiler capable of creating Win32 programs from an input program in a programming language (It doesn't matter which, maybe the simpler the better) Yet I can't find anything right for me and huge compilers like GCC make me extremely confused as they have so many features that I don't know where to start. Is there an OpenSource Win32 micro-compiler for some programming language out there I could take a look at?

  Hello, On my server, I have following setting: open_basedir /home/ :/usr/lib/php :/usr/local/lib/php :/tmp/ :/usr/local/ :/usr/bin Now, I am little bit confused about ending / in the / home / setting, does that mean that all subfolders inside home have same rights? or does it mean that only home files can be accessed? So, basically what is the main difference between: /home/ and /home With example if possible Thank you in advance.

  - by T_t

  Hi!:) In my extension, when a button named "mybutton1" in the popup.html is clicked, it sends a message "getvar1" to the contentscript.js, then the contentscript.js sends a message "i want var1" to the background.html to get an object named "var1".If the button named "mybutton2" is clicked, the contentscript.js gets the "var2" object. How should i do under this condition? What's more, i am a little confused about the chrome.extension.onRequest.addListener method and chrome.extension.sendRequest method.Could someone tell me the mechanism of the two methods? Thanks!

• Why would I want to use server-side JavaScript?

  - by Joseph Silvashy

  I'm confused, I regularly read talk of server-side JS, why would I want to use that? It seems like it would execute way slower than pretty much any other language, it also lacks many conventions that more sophisticated languages have. Is it possible to hand entire objects from the client to the server, manipulate them and return them back? Just struggling to understand the concepts of it.
