  • Can somebody link me to some code where there is a fantastic or a nice use of Inheritance

    - by Soham
    I strongly believe that, reading code and reading good code is key to great programming. If not one of the many. I had been facing some problems in visualizing and having a "feel" of using inheritance to better my code architecture. Can somebody give me some link to good code to emulate, where folks have used inheritance in an absolute "kung-fooey ruthless" manner [in a good way]

  • Preserve embedded album art when converting from .flac to .ogg

    - by Profpatsch
    I want to convert my archived .flac library to .ogg for daily use. Using find ./ -iname '*.flac' -print0 | xargs -0 -n1 oggenc -q6 on the root music folder and then deleting every .flac (having copies of them in archive) seems straight forward, after trying it with one file it worked and all of the tags were transfered, too, except for one: Embedded album art! I always prefer emedded covers over folder images, since I have some albums with varying covers. One possible solution is discussed here, but the script only works if the image is already extracted: Embed album art in OGG through command line in linux One possible solution I thought about was extracting album art from every song (not every song has one, though, and some even 2 or 3!), temporarily saving it and then using the script to include it into the finished .ogg. But then I want to increase the number of processes xargs runs simultaniously to save time, so the temp images need to have a distinct name. Is there a (linux) program that knows how to handle this? Or is there a finished script floating around somewhere? It would be nice if oggenc supported adding embedded coverart and it really is a shame, since these two formats should (in theory) share the same tag format. Edit: 15 days and noone even tries to answer. It’s funny, most of my questions don’t get answered. Too hard? Wrong SE site?

  • Completed downloads freeze Windows

    - by Ben Hooper
    The Issue Shortly after a file download via Google Chrome for Windows completes, the download will get stuck on "0 seconds left" and all other programs (except Google Chrome, for some reason, but browsing will not work) completely freezes into Windows' infamous "Not Responding" state, affecting Explorer particularly badly. Eventually, the programs will recover themselves but they will recover significantly faster if you cancel the file download, relative to how quickly you react. Performing the exact same operation immediately after cancelling the download usually works without issue. This issue occurs when with any file type (.ZIP, .MSI, .MSG, .PNG, .URL, etc) of any size from any source (Dropbox, SourceForge, Imgur, even tiny and locally-generated BLObs created by my own Chrome extension, etc) to any location.   Potential Causes As this issue is so inconsistent, I haven't been able to prove whether the issue is Chrome-specific or being caused by my system or my Chrome configuration but it's happening on both my work and home PCs. I originally suspected that this issue was being caused by security software scanning completed downloads for threats but I'm not as confident in that theory anymore as the issue persisted even after changing my security software from ESET NOD32 and Malwarebytes Anti-Malware Pro to ESET Endpoint to Microsoft Security Essentials.   System Information (of both PCs) Windows version: 7 Service Pack 1 64-bit Google Chrome version: 30.0.1599.101 (but has been happening for a long time)   Screenshots

  • Best IDE macro tools to combat the verbosity of Java syntax for someone with carpal tunnel?

    - by Carlsberg
    I have a bad case of carpal tunnel so I'm looking for an editor that would make my Java programming less painful (literally!). Does anyone have any recommendations for tools that you can add to Eclipse, Netbeans or other IDEs to produce some of the repetitive code that's common in Java syntax? Overall what would be the best code editor for this purpose? (I'm coding on Ubuntu, in case it matters).

  • Compare Quagga to XORP

    - by Sargun Dhillon
    What do you think of Quagga compared to XORP as a dynamic software routing engine? What are the technical merits of each engine comparatively? Additionally, what do most people think of them from a programming view. Who has manipulated networks using these enginers? I was wondering from an OSPF, routing, BGP protocol user's perpspective.

  • Elaboration of A quotation on 'Simple Design'

    - by HanuAthena
    An excerpt from Programming Perls: A Simple Design : Antonie de Saint-Exupery, the Fresh writer and aircraft designer, said that, *"A designer knows he has arrived at perfection not when there is no longer anything to add, but when there is no longer anything to take away."* More programmers should judge their work by this criteria. Can any one elaborate this, please? What does the author mean when he say "...TAKE AWAY"

  • Switch case assembly level code

    - by puffadder
    Hi All, I am programming C on cygwin windows. After having done a bit of C programming and getting comfortable with the language, I wanted to look under the hood and see what the compiler is doing for the code that I write. So I wrote down a code block containing switch case statements and converted them into assembly using: gcc -S foo.c Here is the C source: switch(i) { case 1: { printf("Case 1\n"); break; } case 2: { printf("Case 2\n"); break; } case 3: { printf("Case 3\n"); break; } case 4: { printf("Case 4\n"); break; } case 5: { printf("Case 5\n"); break; } case 6: { printf("Case 6\n"); break; } case 7: { printf("Case 7\n"); break; } case 8: { printf("Case 8\n"); break; } case 9: { printf("Case 9\n"); break; } case 10: { printf("Case 10\n"); break; } default: { printf("Nothing\n"); break; } } Now the resultant assembly for the same is: movl $5, -4(%ebp) cmpl $10, -4(%ebp) ja L13 movl -4(%ebp), %eax sall $2, %eax movl L14(%eax), %eax jmp *%eax .section .rdata,"dr" .align 4 L14: .long L13 .long L3 .long L4 .long L5 .long L6 .long L7 .long L8 .long L9 .long L10 .long L11 .long L12 .text L3: movl $LC0, (%esp) call _printf jmp L2 L4: movl $LC1, (%esp) call _printf jmp L2 L5: movl $LC2, (%esp) call _printf jmp L2 L6: movl $LC3, (%esp) call _printf jmp L2 L7: movl $LC4, (%esp) call _printf jmp L2 L8: movl $LC5, (%esp) call _printf jmp L2 L9: movl $LC6, (%esp) call _printf jmp L2 L10: movl $LC7, (%esp) call _printf jmp L2 L11: movl $LC8, (%esp) call _printf jmp L2 L12: movl $LC9, (%esp) call _printf jmp L2 L13: movl $LC10, (%esp) call _printf L2: Now, in the assembly, the code is first checking the last case (i.e. case 10) first. This is very strange. And then it is copying 'i' into 'eax' and doing things that are beyond me. I have heard that the compiler implements some jump table for switch..case. Is it what this code is doing? Or what is it doing and why? Because in case of less number of cases, the code is pretty similar to that generated for if...else ladder, but when number of cases increases, this unusual-looking implementation is seen. Thanks in advance.

  • Where can I find a good software implementation plan template?

    - by Corpsekicker
    This is not "programming" related as much as it is "software engineering" related. I am required to produce an implementation for additional functionality to a complete system. All I am armed with is knowledge of the existing architecture and a functional spec with visual requirements, user stories and use cases. Is there a standardised way to go about this? I suck at documentation.

  • Links break in IE9 when using Wordpress plugins in non Wordpress Page

    - by mouli
    I have a site that uses SEF URLs and htaccess RewriteRules to serve up the pages. This has worked fine for several years until the arrival of IE9. Now it appears that the links are not being rewritten and the site is dead in the water. I have tried different compatabilty modes, to no avail, and I've played with the Rewrite Rules over and over, tried different doctypes and a few other browser settings. I agree that it cannot in theory be a browser specific problem if the problem is with the htaccess file but this site works in IE8, firefox and chrome. I have run the rewriterule through a validator and it looks fine. Any ideas would be appreciated as I am running out of ideas. The site is www.marlboroughsounds.co.nz a sample link is http://www.marlboroughsounds.co.nz/walking/freedom-walk-queen-charlotte-track/4dfw and the rewrite rule thats not working looks like this: RewriteRule ^walking/.*/([a-z0-9_]*)/?$ /walking.php?act_code=$1 [L] The link fails and it serves up a browser 404 page, not even the custom 404 I have for the site. Any ideas would be much appreciated as I am stumped.

  • Are there any good books to learn C++ if you already know Java and C#

    - by JF LR
    Hi, I would like to know if you have any good books that teach C++ programming without repeating basic stuff. In fact, I already well know Java and C#. I also have a basic knowledge in C and assembly, so I understand a little bit pointer arithmetic, manual memory management and heap based allocation. I was looking at O'Reilly's C++ in a Nutshell and was also wondering if this book would be a good choice. Thank you

  • How I can recover files when the folder shows empty but the files are not deleted?

    - by Borror0
    Yesterday, my laptop caught a virus which caused massive damage. Since them, I have been trying to recover important files before reformatting my computer, a task the virus has not made easy. Restoration points predating the attack have been deleted. Most of my folders show empty. My Start menu is essentially empty, with the exception of Trillian and Mirror's Edge. The same goes for my Desktop, which only has programs which were installed after the attack. Searching for files though my computer is pretty much useless, as it only rarely brings up anything. I suspect most of my files have not been deleted. While my folders show empty, uTorrent still does display them and I can open them from here. Unfortunately, when I select Open Containing Folder, the folder still shows as completely empty even if I'm currently watching a video from that very folder. Further adding evidence to the not-deleted, just-missing theory, the data recovery software I'm using (Restoration) cannot find only find an handful of the missing files. If they were deleted, I could do a forensic recovery to get them back but since they're probably still somewhere on my computer, just out out of my reach, I can't find them. Under those circumstances, is there a way I can recover those files?

  • Implementing Communication Protocols on CC2420 motes powered by TinyOS

    - by stanigator
    I would like to load TinyOS on CC2420 radio motes to operate on certain communication protocols (e.g. epidemic routing, probabilistic routing, etc.). However, I have no prior experience in programming motes to perform the protocols I want. I'm just wondering about the most applicable resources for reference and how difficult (if not impossible) was implementing such mentioned protocols. It would be great to hear from you. Thanks in advance!

  • piping in UNIX doubt

    - by Happy Mittal
    In The Unix Programming Environment by K & P, it is written that " The programs in a pipeline actually run at the same time, not one after another. This means that programs in a pipeline can be interactive;" How can programs run at same time? For ex: $ who | grep mary | wc -l How grep mary will be executed until who is run or how wc -l will be executed until it knows results of previous programs?
