  • Getting into game/game engine programming

    - by Darkslash
    So I am interested in learning game programming, but I really have an interest in the lower level engineering in games. I have openGL experience, and I am really interested in learning more about implementing AI, Physics, etc. I have a computer science degree, so I really like getting into technical stuff. Many times when I ask about this sort of thing, I get a lot of "Use an engine", "Use Unity3d", "Why waste your time writing code that already exists", etc etc. My idea was to use simpler libraries such as SFML or XNA so that I could learn how to implement the more complex systems. The thing is, although I do want to write games, I want to learn things that using something like Unity simply doesnt teach you. My goal is not to make a current generation quality 3D game to sell, I just want to make some cool smaller games and learn all I can about the programming side of game development. Is this something that people just do not do anymore? It seems like everywhere I turn people are using Unity or UDK or GameMaker. I fully understand why you would use a tool like these, but I cant see how they would suit my purposes. So where does someone like myself turn? Am I trying to learn something that people just do not bother doing anymore? Is the innovation in this area gone and just all about gameplay now? Im sorry if this question seems silly, but I am genuinely interested in knowing more about this and meeting more people who are interested in this sort of thing.

  • DVD Drive can read a DVD title and file contents (very slowly) but not play DVDs

    - by Daisetsu
    I've been able to watch DVDs in the past on this computer when it was running XP. I recently upgraded to windows 7 and haven't watched a DVD since then. I put a DVD in and it took quite a long time but windows finally found the disk title, and I was able to explore directories (saw folder like VIDEO_TS). The problem is when I try to have video players play the DVD I just get an error in VLC. It wouldn't tell me the exact error (said to check the log and I don't know where that is). Do I have to install some special drivers/certs in windows 7 to play video?

  • Is there a modified LGPL license that allows static linking?

    - by Petr Pudlák
    úLGPL requires that it if a program uses LGPL-ed library, users must be able to re-link the program with a different version of the library: ... d) Do one of the following: 0) Convey the Minimal Corresponding Source under the terms of this License, and the Corresponding Application Code in a form suitable for, and under terms that permit, the user to recombine or relink the Application with a modified version of the Linked Version to produce a modified Combined Work, in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source. 1) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (a) uses at run time a copy of the Library already present on the user's computer system, and (b) will operate properly with a modified version of the Library that is interface-compatible with the Linked Version. ... However in some cases, this can pose considerable difficulties. In particular, Haskell programs are almost always statically compiled. Moreover, the compiler does cross-module optimizations so it's very hard to satisfy this condition. (See this link at Haskell Wiki.) Therefore, I'm looking for a standard LGPL-like license that wouldn't require the possibility of re-linking. Some projects use their own modification of LGPL, for example wxWidgets. But I'd rather use some standard license that is somewhat more official, perhaps checked by some law experts, and (L)GPL compatible. Is there some like that? (Also I'd be interested to know if are there some unforeseen consequences of such a modification of LGPL.)

  • Safari on Mac OS X Cache lasts after 'Empty Cache'

    - by Mitch
    So, I broke a website with some server changes oops. I roll back the changes I made, hit cmd-R, and oh noes, it is still broken. But I relax thinking, there must be something held in safari's cache so I press the handy 'Empty Cache' button. Hit cmd-R for refresh it is still broken. I'm really worried that I've done it and broken something bigtime. But first decide to check on a hand win xp computer, and voila it works. So the question is how do you "really" clear the cache w/o restart safari, I have many browser windows open a restart every time I make a server side change will ruin me. Any suggestions? Thanks!

  • Why do I get Apps in Windows 8 listed as 'Not available' sometimes?

    - by keith
    What affects this, and if possible, how can I prevent this? Or maybe how can I get them to be available sooner or all the time? This pretty much happens to my game apps connected to Xbox live and a few others from time to time. It never happened before I updated the computer, but I haven't had the PC long anyway. Could it be that after updates that need a restart it does this as well (I've done two of those so far)? Anyhow, I'm frustrated, I keep clicking on a app and it not responding. The problem fixes itself at some point, but I have not been able to stare at my PC long enough to figure out how long it takes or what happened.

  • Why can't I run Compiz?

    - by jasoncruz98
    I installed Ubuntu 11.10 on my laptop. The main reason I switched to Ubuntu is because I wanted to use Compiz. The first thing I did was to go to Additional Drivers and install ATI/AMD Proprietary FGRLX Graphics Driver. There was also another one available, ATI/AMD Proprietary FGRLX Graphics Driver (post-release updates), but I didn't install that one, because it basically meant the same thing to me as the one I already installed. Next, I went to the ubuntuguide.org Oneiric Wiki http://ubuntuguide.org/wiki/Ubuntu:Oneiric#Compiz_Fusion So I followed the instructions there and ran this command in terminal: sudo apt-get install compiz compizconfig-settings-manager compiz-fusion-plugins-main compiz-fusion-plugins-extra emerald librsvg2-common But then, the terminal window said that the package "emerald" could not be found. So, I ran this command instead: sudo apt-get install compiz compizconfig-settings-manager compiz-fusion-plugins-main compiz-fusion-plugins-extra After that, I installed Fusion Icon by running this command: sudo apt-get install fusion-icon I restarted my computer, searched for Compiz Config Settings Manager, and clicked on it. Then, I activated Wobbly Windows. I logged off and logged back on again, but there was no wobbly windows effect. So I tried clicking on Fusion Icon, but it never started. Can someone please tell me what I did wrong here? Because I see everyone seems to be able to run Compiz except me. I really need to start Compiz, or else I think I'm going to uninstall Ubuntu.

  • Virtualizing WindowsXP on Linux Fedora 12 for Photoshop....

    - by Rae
    I am running a Linux server from 2000, I have Fedora12 installed as the OS. I know you can virtualize Windows XP on the system to be able to run Windows programs, but the problem is I My server has only one 1333Mhz Pentium 3 processor and 1G of Ram. granted this is a pretty kick ass computer for the day, but lacking the second processor I'm afraid that I will not be able to run Windows virtualization to support Photoshop CS3. Is there any program out there that runs similar to Photoshop, like windows Digital Image suite 10, that will run smoothly in my Linux Fedora 12 environment? or can I virtualize windows and run the Windows digital image suite 10, without slowing or corrupting my system?

  • My New Job

    - by Stuart Brierley
    Last year I started a new job with a logistics company in the North of England, where I was responsible for the management, design and development of IT Integration strategies, architectures and solutions using BizTalk Server 2009.  This included the design and implementation of the BizTalk Server 2009 infrastructure, the definition of development standards, mentoring a fellow developer in the ways of BizTalk and migrating a number of existing solutions from Softshare over to BizTalk 2009. Unfortunately I then realised that, following this initial set up, there didn't actually seem to be that much BizTalk work for me to get stuck into and reluctantly I have now moved on from this role to a very similar role with the country's largest office supplies company.  Based in Sheffield, we distribute office supplies on a UK wide basis and computer supplies across Europe. The situation here is slightly different than when I first joined my previous employer.  Whereas that was a green field installation with no previous BizTalk solutions in place, my new employer currently has a number of live BizTalk 2000 (!) and BizTalk 2006 solutions in place.  Unfortunately the infrastructure around these is less than ideal; with no clear distinction between development and test environments and no source control what so ever! We are currently building a proposal for a new BizTalk Server 2010 implementation, where I am hopeful of being able to implement fully independent development, test and pseudo-live environments, alongside an enterprise level live installation.  We should also be introducing Team Foundation Server to the development process, thereby giving us some much needed source control capabilities. Following this is likely to be a period of migration for the existing BizTalk Solutions, along with the onward development of new projects and initiatives - I'm hoping to be a busy man for the forseeable future :o)

  • Crystal Reports 8 - Error 533 PESStartPrintJob

    - by Federico Giust
    We have on the company I work for an application built in Delphi V with Crystal Reports 8. We all know that Crystal & Delphi can be temperamental sometimes and the worst thing is, nearly no detail on the error. Also there is a big lack of documentation on the web about this. There's lot of people with similar issue but no solution. The error I'm talking about in particular is the one on the image below. This happens when trying to print any Crystal Reports on screen. This has happened sometimes in the clients computer and it was hard for us to replicate on our environment. Since it's an old version of Crystal it is very hard to find any helpful documentation to know the exact source of the problem.

  • Fun with upgrading and BCP

    - by DavidWimbush
    I just had trouble with using BCP out via xp_cmdshell. Probably serves me right but that's a different issue. I got a strange error message 'Unable to resolve column level collations' which turned out to be a bit misleading. I wasted some time comparing the collations of the the server, the database and all the columns in the query. I got so desperate that I even read the Books Online article. Still no joy but then I tried the interweb. It turns out that calling bcp without qualifying it with a path causes Windows to search the folders listed in the Path environment variable - in that order - and execute the first version of BCP it can find. But when you do an in-place version upgrade, the new paths are added on the end of the Path variable so you don't get the latest version of BCP by default. To check which version you're getting execute bcp -v at the command line. The version number will correspond to SQL Server version numbering (eg. 10.50.n = 2008 R2). To examine and/or edit the Path variable, right-click on My Computer, select Properties, go to the Advanced tab and click on the Environment Variables button. If you change the variable you'll have to restart the SQL Server service before it takes effect.

  • Ralink RT3060 wireless device configuration on ubuntu 12.04

    concerning How do I get a Ralink RT3060 wireless card working? I'm running Ubuntu 12.04 with a 'LWPX07 Edimax EW-7711In 150M 1T1R WL PCI Card' which has a rt3060 chip.

  • Problems setting up home web server

    - by putmatrix
    Has anyone been able to get a server working with the router smcwbr14t-g? Although I have been able to get Apache set up correctly and my website works on the internal IP 192.168.2.101, I've been running into a dead end when trying to get it to show up on my external IP. In my router, there is no option for port forwarding, but there are options for a 'virtual server'. Following the manual, I have it set up like this: http://imgur.com/zrcV7.png I also disabled the firewall. I configured Apache to listen to ports 80, 81, and 443, none of which solved the problem. However, the IP's 192.168.2.101:443 and :81 load fine. The problem is that I still cannot load the web site from my external IP, either from my computer or outside.

  • Radeon 5850 Why am I not getting 3 monitors up as a choice ??

    - by Jan
    Ive just bought the top end ATI Radeon card with 2 normal monitor ports and a HDMI. The idea was to continue using my dual screen setup as always and to use the last plug, the HDMI on my TV. I got a new 52 inch HD TV with all the necessary bits. This should work fine. But.. in Display Properties I still get only my 2 monitors up as options. Not the Digital TV. When I unplug 1 monitor and restart the computer, I get the TV and the other monitor. But never all 3 at the same time. Why is this ? Where can I go to tell it that I need all 3 screens at the same time. Also I get a message saying my gfx card also gives sound through the HDMI cable.. But the TV tells me its recieving a sound format that it does not understand. Any ideas on that too while were at it ?

  • Why do browsers have so many possible exploits?

    - by Beau Martínez
    When browsing I am ocassionally given warnings about pages that host malware "that could damage my computer". I am seriously perplexed as to why, in 2010, browsers still have possible exploits and can be cracked. My question is "Why?". I'm assuming it's because of the quick development that occured in the browser wars which were unsufficiently tested, but I'm unsure. Surely WebKit would have patched all the issues in KHTML, or Gecko sorted out the flaws in Netscape's engine, and the IE coders sorted through their codebase to eliminate possible flaws? (Somewhat related: http://superuser.com/questions/117770/which-browser-is-the-most-secure-research-and-practically-based.)

  • Windows Experience Index could not be computed

    - by Alexey Ivanov
    I've upgraded recently from Windows Vista to Windows 8. When I try to rate my computer, it accesses DirectX 9 performance, then processes to DirectX 10 tests: And it gets stuck at this point. In 5–10 minutes, it shows error message: The video card is rather old: Mobile Intel 965 Express Chipset Family. I'm pretty sure it does not support DirectX 10. Why does Windows assess it with DirectX 10? And how can I make it skip DirectX 10 tests and get the system rating? The driver was installed automatically by Windows 8 from Windows Update.

  • How does SSMS and SQL Server Licensing work?

    - by DrewK
    Could not get a efficient enough answer from MSFT or some of their vendors. Trying to determine exactly how the licensing works before dropping the money on it. Looking to get Server/CAL. We will have the server at our datacenter and then be using SSMS remote on each developers computer. That is, installing SSMS on all developers machine. I am not familiar with MSFT licensing (postgresql & mysql). If I were to pay for the server license and 5 CALs does that mean we can install SSMS locally on each machine. Does each CAL have a specific lic. # that is entered when installing SSMS? We were messing with just the trial edition and the only way I know of installing SSMS is using the full sql server install and choosing only SSMS, it still requires a license number. Any information would be very useful.

  • unknown module in my server to get PHP errors in HTML tables

    Sorry to ask this... I manage Apache and PHP in my computer. But having installed a lot of things, I've lost track of some of them. (Things I find really useful to have at my job, or to restore in case of emergency). The problem is that I have installed this thing which displays PHP errors in a nice and colored html table, but can't remember what I have installed or configured to get it work like it. Can you give me a hint about it? I'm using Debian Lenny, Apache 2.2 and PHP 5.2 Here's a screenshot: Thank you very much for reading. Javier

  • Free internet radio station server software with remote broadcasting?

    - by Zachary Brown
    I am in the process of creating an internet radio station, but the two djs I have for it are not able to be in one place. I need for them to be able to login to a web based broadcasting session that still has full functionality. They need to be able to broadcast thier live shows with talk and music. The music will be stroed on the server. I have checked out the Broadwave media streaming server from NCH, but ti does not have the ability to login as a dj from a remote computer. I don't have any money for this, so I need it to be free. If this is not possible, I need it to be cheap!

  • How to open the Quota Entries list for a given drive from a shortcut or command line?

    - by Indrek
    Is it possible to open the Quota Entries list for a given drive from a shortcut or the command line in Windows? And if so, how? I'm not talking about managing quota entries from the command line (fsutil quota), I'm looking for a way to get directly to the Quota Entries GUI rather than going through My Computer → right-click on a drive → Properties → Quota tab → Show Quota Settings → Quota Entries... I managed to find out (using Process Explorer) that the backend process is dllhost.exe, and the DLL in question should be dskquoui.dll, so it should be possible to run it directly with rundll32.exe, but I'm not sure of the exact syntax. Any ideas?

  • Macbook cannot see specific wireless network after being connected to it for a while

    - by donut
    Okay, so there's a single wireless network that my laptop has troubles with. My Macbook Pro used to be fine with it until it changed to using channel 13 (or 11?). Since then, after being connected to it for a while it disappears from my laptop's view. Other networks are showing up fine and other computers (including several Macs) have no troubles connecting to this network. If I clear my system cache using Onyx and then restart (sometimes a couple times) my laptop can see and connect to it again. But it seems that if I disconnect and try reconnecting I have to clear my cache again. One thing to note is that if I put my computer to sleep while connected to this network it has no problems reconnecting on wake up. I've got a 15" Macbook Pro 2,2 with Leopard 10.5.8.

  • Coloring The Z Shell[closed]
