  • Amazon EC2 pricing question

    - by Industrial
    Hi everyone, I took my first step today on working with cloud servers and chosed Amazon EC2 for this project. Since I am a bit of a newcomer on this, I didn't fully understand their pricing: What happens when a instance is idling with no connections being made. Does it still cost us money? It would be sad to have instances idling and costing us money when we do not use them... Thanks a lot!

    - by aaa
    hello. Is there significant cpu/memory overhead associated with using automatic arrays with g++/Intel on 64-bit x86 linux platform? int function(int N) { double array[N]; overhead compared to allocating array before hand (assuming function is called multiple times) overhead compared to using new overhead compared to using malloc range of N maybe from 1kb to 16kb roughly, stack overrun is not a problem Thank you

  • Do we still need backup code for people who have javascript disabled?

    - by SLC
    I hear about it a bit in tutorials that I watch, that certain things won't work if javascript is disabled. Occasionally I see workarounds. The question is, are these relevent? I can't imagine anyone not having a javascript enabled browser nowadays, except the most ancient of phones, and chances are your page won't render on them properly anyway. Do people still bother to write backup code for javascript being disabled?

  • CSS: is there any way to have the same relative positioning even if the previous element have differ

    - by Patrick
    hi, I have a sequence of couples of elements. (.div1, .div2) I'm using position:relative attribute on .div2 to move it a bit on top and right with respect to div1. However .div1 elements have different content and heights, so the relative positioning of .div2 is not consistent (they sometimes are too high, sometimes too low). .div2 { position:relative; left:200px; top:-300; } thanks

  • Is there a good Python library that can parse C++?

    - by csbrooks
    Google didn't turn up anything that seemed relevant. I have a bunch of existing, working C++ code, and I'd like to use python to crawl through it and figure out relationships between classes, etc. EDIT: Just wanted to point out: I don't think I need or want to parse every bit of C++; I just need something smart enough to pick up on class, function and member variable declarations, and to skip over function definitions.

  • detect when a webpage is updated

    - by Martin Trigaux
    Hello, There is a website (very simple) which will be updated soon and I'd like to receive an alert at the moment it changes (like a sound, a popup,...) I guess I should send request every x minutes and compare the result with what's now but I don't know how to do that. I don't really care about the language used, I know java, python, php, a bit of c and bash (I'm on linux)... Thank you

  • Android which type of feed is faster for rendering?

    - by ppshein
    Currently, I've developed android news application for my client. In this project, I've used JSON feed for content sync but I feel rendering JSON feed in android is a bit slow. Perhaps, due to my coding or something else. Now want to try XML feed instead of JSON. Thus please let me know which type of feed (between XML and JSon.. but let me know any good feed any other else) is faster for rendering in Android?

  • Java 1.7ea: Files.probeContentType(path) returns null

    - by Cybertizzen
    Hi, I'm having a bit of a strange problem with an application using the Files.probeContentType(path)-method to test for file type: On both my Ubuntu and Fedora systems, it works fine, but when moved to a RedHat Enterprise server (2.6.18-194.el5 #1 x86_64 x86_64 x86_64 GNU/Linux), it only returns null. I'm using java 7 early access (1.7.0-ea-b84). I have to use this version due to functionality that isn't included in 1.6. Does anyone have an idea of what might be the problem here?

  • How does CouchDB handle UTF-8?

    - by borghe
    I'm quite puzzled by CouchDB: if I send a PUT request with some JSON string fields encoded as UTF-8, the non 7 bit ASCII characters get converted to the "\uXXXX" escape sequence. Is there any way to tell it not to escape UNICODE?
