  • Parsing glGetShaderInfoLog() to get error info. Is this reliable, or is there a better way?

    - by m4ttbush
    I want to get a list of errors and their line numbers so I can display the error information different to how it's formatted in the error string, and also show the line in error. It looks easy enough to just parse the result of glGetShaderInfoLog(), look for "ERROR:" then read the next number up to : and then the next, and then the error description up to the next newline. But the OpenGL docs say "Application developers should not expect different OpenGL implementations to produce identical information logs." Which makes me worry that my code may behave incorrectly on different systems. I don't need them to be identical, I just need them to follow the same format. So is there a better way to get a list of errors with line number separate, is it safe to assume that they'll always follow the "ERROR: 0:123:" format, or is there simply no reliable way to do this? Thanks!

  • How do I find a proprietary driver for the Intel graphics card I have?

    - by user69798
    I have an Intel corporation core processor integrated graphics controller (rev 18), and I am trying to get a proprietary driver for my graphics card so I can play Amnesia from the Humble Bundle. I am a female that can easily follow directions but doesn't know much about Linux yet. If you give me precise directions, I will follow them so you can help me fix the problem. I would really appreciate it! My laptop is a Dell n7010. Additional info: I believe that it is the graphics card that is causing Amnesia to crash, but I am unsure. I have tried running it on the lowest possible settings, and it crashes after the first loading screen. :( Also, I installed via the Ubuntu Software Center after purchasing the Humble Bundle. I have not tried the other games yet.

  • AndEngine player, background and camera

    - by valdemar593
    I'm developing a 2D shooter using AndEngine. At the moment I'm trying to make the camera follow the player. As I've understood the common approach is to use the SmoothCamera zooming it and setting the chased entity. The problem is that the camera follows the player WITH background moving also (RepeatingSpriteBackground), so it looks like the player doesn't move at all though the actual position changes. So I don't really get how to make the camera follow the player and have the background not moving. Thanks in advance.

    I my c# program I have to perform 5 steps(tasks) sequentially. basically these five should execute one after the other only the previous task performed is success. Currently I have done it in following style. But this is not very good code style to follow. var isSuccess=false; isSuccess=a.method1(); if(isSuccess) isSuccess=a.method2(); if(isSuccess) isSuccess=a.method3(); if(isSuccess) isSuccess=a.method4(); if(isSuccess) isSuccess=a.method5(); How can I re factor this code.

  • Garbage Collection Basics

    - by mikew_co
    Java Is an awesome programming language and platform. One of its better features is automatic garbage collection. Ever wondered how that works? I have written an online web course outlining the basics. Much of what is included has been published before in various white papers and such. However, this is updated for JDK 7 and includes some nice illustrations of the steps involved. Hope you like it. Garbage Collection Basics. A follow-on web course on the G1 garbage collector should follow in a week or so.

  • Recommended learning path?

    - by stairmast0r
    First, my current standing: I know C++ at an.. advanced beginner level? I've gone through a book, I know the syntax well enough, I know a fair amount of standard library functions, and I've programmed some simple console stuff with it. I'd probably be able to program more with it if I knew how to structure a program, but I just can't seem to wrap my head around the whole concept of structuring something remotely complex. I've messed around with Java for a day or two, and the syntax was extremely easy to get the hang of, except that I didn't really know any functions. I'm plenty willing to learn, and to work hard to do so, but I don't really know where to go from here. Now, at the risk of sounding cliche, what I'd like to become is someone like the great three of id; Carmack, Romero, and Abrash. To be considered a genius. I believe anything can be learned, and nothing mentally limits anyone except lack of desire to learn. But I don't know how to learn this. They learned by doing, and making do with what resources they had. On the other hand, I have access to almost any books I want, access to the internet, and access to a more than capable computer and software. Should I learn more languages? Assembly? LISP? BASIC? Haskell? Should I dive straight into advanced topics like OpenGL? Or should I wait until I feel I've come closer to mastering the simpler things, like console programs, first? Should I follow tutorials? Should I follow books? Should I just dive into writing something and follow a reference manual as I go? What order should I do all this in? How should I do it? I want to completely master this; to be considered a genius. The most perfect career I can imagine is to start the next id. I have the drive to do it, I just don't know where to begin...

  • Drop in rankings after removing sitewide backlinks

    - by user319940
    Here's the scenario: I have a small web design business and was using a branded backlink on the bottom of all client sites. Recently this has become a bit taboo with the Google updates so I went back to a few of my sites and made it so there's only a homepage backlink. After doing this, I've had a drop in rankings, despite this apparently being a best practice. Is this likely a temporary drop that will pick back up? For any new sites, I still want to have a link on all pages of client sites as it's good advertising. I plan to have a do-follow homepage link and then no-follow every other link - is this a good idea?

  • How to boot Linux from a 16gb USB flash drive

    - by Chris Harris
    I'm trying to install Linux on a single partition of a USB flash drive that's larger than 4gb. The first place I went to is http://pendrivelinux.com. I can follow these instructions for installing Xubuntu 9.04 perfectly, which unfortunately break down when I try to scale it up beyond 4gb. There are several other tools to do this (unetbootin and usb-creator) which follow a very similar formula. I figured out that a big problem of mine was that all of these tools assume the USB drive is formatted in FAT32, which unfortunately cannot hold a single file larger than 4gb. This is unfortunate because I want to use just one partition, so that my persistance file, casper-rw, looks like one big partition to the OS once I've booted off of the USB drive. I then tried following a myriad of instructions involving formatting the drive as one large ext2 filesystem and using extlinux to create a single bootable ext2 file system. This doesn't work for me however, after about 20 attempts verifying and slightly tweaking the formula, I cannot seem to get a "good" bootable ext2 file system built. I'm not entirely sure what's going on, but it seems as though no matter how hard I try, I cannot get the ext2 file system to remain coherent after copying the Linux ISO contents over, copying the MBR, and executing extlinux to create the ext bootloader. Every time, after I follow these steps (in any order) and reboot, I get an unbootable USB drive. If I then mount the drive under Linux again, I see a mess of a file system (inodes have clearly been screwed up somewhere along the way). I suspected that the USB drive wasn't being fully flushed, so I tried using the "sync" and "unmount" commands before rebooting which didn't affect things at all. I guess I have several possible questions - but let's start with the obvious - is there something I'm missing to create a bootable ext2 USB flash drive that's large (e.g. 16gb)?

  • NVIDIA GeForce GT750M drivers for Ubuntu 13.10 on iMac

    - by Eugene B
    I have just got a new iMac 14.3 with 21.5' display. It has Intel i7 processor and NVIDIA GeForce GT750M graphics card with GPU (Device ID: 0x00fe9). I have installed Ubuntu 13.10 on it (dual boot with refit). Everything works fine apart from graphics. It is clear that graphics' not accelerated, and there are no drivers suggested in the "Additional drivers" section. I have tried to Install nvidia drivers from the repository. Download nvidia drivers and install them manually. Follow instructions here. Follow instructions here. Follow instructions here. Install bumblebee. Play around with xorg.conf file. Blacklist nouveau. As you may guess, nothing worked. The weirdest thing is, that when I boot from a LiveCD, it picks up screen resolution and all the rest correctly, though when I install the system to my Hard Drive it clearly does not have proper drivers. Does anyone have any suggestion what to do?

  • Conventions for order of parameters in a function

    - by Andy
    In writing functions my brain always spends a few milliseconds to check which order of parameters would be best for a given function. should I write: public Comment AddComment(long userID, string title, string text) Or probably: public Comment AddComment(string title, string text, long userID) Why not: public Comment AddComment(string title, long userID, string text) Do you follow any rules when ordering the parameters for your functions? Which parameter would you place first and which would follow?

  • Correct way to persist Quartz triggers

    - by davioooh
    I'm quite new to Quartz and now I need to schedule some jobs in Spring Web App. I know about Spring + Quartz integration (I'm using Spring v 3.1.1) but I'm wondering if it's the right way to follow. In particular I need to persist my scheduled tasks in a DB so I can re-initialize them when application is restarted. Are there some utilities provided by Spring scheduling wrapper to do this? Can you suggest me some "well known" approach to follow?
