  • C++ MPL or_, and_ implementations

    - by KRao
    Hi, I am trying to read the boost headers to figure out how they managed to implement the or_<...> and and_<...> metafunctions so that: 1) They can have an arbitrary number of arguments (ok, say up to 5 arguments) 2) They have short circuit behavior, for example: or_<false_,true_,...> does not instantiate whatever is after true_ (so it can also be declared but not defined) Unfortunately the pre-processor metaprogramming is making my task impossible for me :P Thank you in advance for any help/suggestion.

  • JavaScript / HTML highlighting / debugging in Eclipse using PhoneGap

    - by Jason Hartley
    I am writing an app using PhoneGap for Android in Eclipse. Since the project is an Android project, it's in a Java perspective. For whatever reason, Eclipse won't highlight HTML and JavaScript for me while in an Android/Java project/perspective and switching to the JavaScript perspective doesn't highlight the code either. Without highlighting or debugging tools, the debug process is very slow. How do I tell Eclipse to highlight HTML and JavaScript for me while working in a Java Environment?

  • How does porting between Linux and Windows work?

    - by Matt
    If a particular piece of software is made to be run on one platform and the programmer/company/whatever wants to port it to the other, what exactly is done? I mean, do they just rewrite linux or windows-specific references to the equivalent in the other? Or is an entire rewrite necessary? Just trying to understand what makes it so cost-prohibitive that so many major vendors don't port their software to Linux (specifically thinking about Adobe) Thanks

  • rawurlencode() and urlencode() not working in CodeIgniter

    - by Keith Chason
    I am trying to encode a string into a safe url for generic purposes, and neither rawurlencode() nor urlencode() work when using CodeIgniter. I have used them and they work pefectly fine with straight PHP, but for whatever reason, it doesn't work. I haven't been able to find any others with this problem and thus no solution. Code: <a href="/search/degree/<?=rawurlencode($row->degree)?>" class="element_link"><?=$row->degree?></a>

  • PHP & CodeIgniter Error: open_basedir restriction in effect

    - by iamdadude
    open_basedir restriction in effect. File(/var/www/vhosts/domain.com) is not within the allowed path(s): (/var/www/vhosts/domain.com/httpdocs:/tmp) How do I securely fix this? This is preventing me from listing and creating directories outside of the current directory. What I mean by securely is that I don't want to remove a piece of code from a configuration file and potentially make it easier for hackers to do whatever.

  • Transcoding audio and video

    - by Lance Fisher
    What is the best way to transcode audio and video to show on the web? I need to do it programmatically. I'd like to do something like YouTube or Google Video where users can upload whatever format they want, and I encode it to flv, mp3, and/or mp4. I could do it on our server, but I would rather use an EC2 instance or even a web service. We have a Windows 2008 server.

    - by gleb-pendler
    You have an array size n and a constant k (whatever) You can assume the the array is of int type (although it could be of any type) Describe an algorithm that finds if there is an element(s) that repeats itself at least n/k times... if there is return one. Do so in linear time (O(n)) The catch: do this algorithm (or even pseudo-code) using constant memory and running over the array only twice

  • how to make Xcode indentation from beginning of previous line?

    - by Mikkel
    ok, possibly insanely n00b question or something i have overlooked in Xcode prefs: On pressing return, in stead of Xcode's syntax-aware indentation doing smart indent from whatever brackets i've used on the previous line, how can I make it so Xcode indents just from the beginning of the previous line? From the picture below, first block of code is what i got, second block of code is what I want. Visual representation:

  • tool to auto-format R code

    - by Keith
    Is there any tool (editor, script, whatever...) available that can automatically reformat R code? It does not need to be customizable but it must be able to recognize statements separated by either semicolons or newlines since this code has both. If it can put all statements on a separate line, consistently indent code blocks and consistently place braces I will be very happy.

  • If you could take one computer science course now, what would it be?

    - by HenryR
    If you had the opportunity to take one computer science course now, and as a result significantly increase your knowledge in a subject area, what would it be? Undergraduate or graduate level. Compilers? Distributed algorithms? Concurrency theory? Advanced operating systems? Let me know why. (Note that I appreciate this isn't a far fetched scenario - but time and inertia might be preventing people from taking the course or reading the book or whatever)

  • UIWebView comparing current and defined URL's with a loop depending on result

    - by Syleron
    I am trying to compare the current url in webView with a defined url say google.com so in theory.. NSURLRequest *currentRequest = [webView request]; NSURL *currentURL = [currentRequest URL]; would give us our current url... NSString *newurl = @"http://www.google.com"; this would give us the compared to defined url while (!currentURL == newurl) { //do whatever here because currentURL does not equal the newurl } This does not seem to work though.. solutions?
