• Getting Started with 2d Game Dev (C++): DirectX or OpenGL?

  - by Dfowj

  So, i'm a student looking to get my foot in the door of game development and im looking to do something 2D, maybe a tetris/space invaders/something-with-a-little-mouse-interaction clone. I pointed my searches in the direction of C++ and 2d and was eventually lead to DirectX/OpenGL Now as i understand it, all these packages will do for me is draw stuff on a screen. And thats all i really care about at this point. Sound isn't necessary. Input can be handled with stdlib probably. So, for a beginner trying to create a basic game in C++, would you recommend DirectX or OpenGL? Why? What are some key feature differences between the two? Which is more usable?

• HTML5 für APEX Entwickler: Anwendungen der nächsten Generation

  - by Carsten Czarski

  HTML5 ist nicht umsonst eines der meistdiskutierten Themen in der Anwendungsentwicklung: Es eröffnet dem Anwendungsentwickler völlig neue Möglichkeiten zur Gestaltung von Web-Benutzeroberflächen. So ist es möglich, mit HTML5 auf das GPS eines mobilen Geräts zuzugreifen - aber das ist bei weitem nicht alles: Mit SVG und CANVAS-Objekten wird es möglich, frei auf der Browseroberfläche zu zeichnen - die FileReader API erlaubt es, vom Anwender ausgewählte Dateien noch vor dem Hochladen auszulesen. Diese Möglichkeiten erlauben es, völlig neue Anwendungen zu entwickeln - eben Anwendungen der nächsten Generation. Im Webseminar am 8. November wurden einige der Möglichkeiten von HTML5 vorgestellt und gezeigt, wie man sie in APEX-Anwendungen nutzen kann. Die Foliensätze und APEX-Beispielanwendungen sind ab sofort verfügbar: https://apex.oracle.com/folien Schlüsselwort: apex-html5

• Not getting paid for hours you've worked?

  - by Mercfh

  So I was reading from a previous thread about App vs Game Development Here Which brought me to this site: Clicky Alot of it talked about devs working something like 85 hours a week.....and not getting paid overtime, or anything. Just getting paid for the 40 hours.....Is this normal for most software companies? I mean where I work im only an entry level guy....but I get overtime, and Anything over 40 hours is considered this. But it got me thinking "Holy crap" I could never do that. My FREE time is important to me. But is this commonplace in most software companies? or...more a rarity to certain types (game development, etc) Cause it got me scared! Like I understand having to put some extra hours in for a project......but like 80! thats ridiculous.

• Faulty memtest result

  - by dhojgaard

  I've been a bit suspicious about my RAM lately. They seem not work like i expect them to. For instance i run a lot of Virtual Test Environments in VMware Workstation and lately Ubuntu starts to lag just running 4 virtual machines each dedicated 512 MB. BTW im having 6GB memory on my laptop. This did not use to be a problem for me on my last laptop that even had a lot lower CPU resources. So i was led to try a memtest after reading some websites about RAM testing. So i did a memtest overnight but when i woke up this morning i was just looping and i could not Exit or do anything. It was just looping the number of errors besides test 7 which you can see in the lower right part of the screenshot. Can anyone interpret this screenshot for me? Do i have a faulty set of RAMs?

• Extremely slow upload speeds in nautilus with FTP

  - by Oscar Godson

  I was at home uploading a WP site and it's maxing at 4.2kb. I did a speed test and im getting ~1MB upload (my home ISP caps it out at that). I uploaded a 5MB file via Chrome, to test, and it uploaded within 2 mins. The file uploaded was a wordpress.xml file through the uploader. Same file in nautilus is taking forever. To upload this WP site and all the plugins took 1 hour. Any ideas of why or how? P.S. I've been using my hosting company also for years and they've never had any speed issues uploading.

• Xcode Video From UITableView [migrated]

  - by Luis Felipe Beltran

  I have created different UITableViews. Each of these are dynamic tables that contain NSarrays of words. Right now When a cell is tabbed it takes the user to another View (simple view controller) that has a label and a UIImageview that displays a picture. My problem is that I also want to show video. Some of these words need to show pictures, and others need to show video. I have shown video before but I have done it using a button. I need help! I would appreciate if you guys could help here. Again, Im trying to show a video from a UITableView after the user tabs a cell. (I have many videos not just one, so dynamically would be better if possible)

• Why does waking from hibernate take nearly ten minutes on 11.10?

  - by Shane O'Connor

  Im running 11.10 64bit on a Dell XPS 15 L502x laptop. It uses an i5 proc and has 16Gb ram. Whenever I close the lid on the laptop I have it set to hibernate as I want to continue whatever I was previously running. Generally that is simple text editing, so my mem usage would normally be only a Gb or 2. When I open the lid and it resumes from Hibernation, it takes up to ten minutes to do so. Extremely frustrating. Is there anything I can do to make hibernate function properly. On windows it used to wake from Hibernation in less than 30 seconds. Its really frustrating and souring my experience with Ubuntu. Any help would be gratefully appreciated! Thanks guys/gals! S

• What tools are available for remote communication when working from home or with a distributed team?

  - by Ryan Hayes

  My supervisor is allowing my team to dip our toes in the water of working from home. Considering a recent aquisition of another company is requiring some employees to love this new idea which will hack up to an hour off their commute into work every morning, I really want this to succeed. In order to make it a success, we need good tools to make our lives a lot easier. We currently are set up with OpenVPN, and Team Foundation Server 2010 with SharePoint 2010, and use Live Messenger (for SharePoint integration and easier remote desktop) for IM. These are just what we use (and they are currently working well) , but you can suggest other products. So, what are some great tools that will helps us collaborate, communicate, and generally work together when we're hours apart?

• Remove bottom panel from a remastered LiveCD

  - by Uri Herrera

  How can I remove or autohide to 0 the bottom Gnome panel from a remastered liveCD and autostart AWN (or any dock for that matter...) to replace it? , just as moonOS 4 (the distro that gave me the idea to try to do this) Using this command to enable the auto hide gconftool-2 -t bool -s /apps/panel/default_setup/toplevels/bottom_panel/auto_hide "true" i Figured out how to Autostart AWN,however that involves removing BOTH panels, so im not quite there yet Using UCK gconf-editor to manually edit the option to auto hide the bottom panel doesn't work, when testing the livecd BOTH panels are still there, even though i use the command and then run gconf-editor to check that the option is eneabled, which it is, however, once the livecd starts the autohide feature is disabled

• GLSL Shader Effects: How to do motion blur, etc?

  - by DevilWithin

  I am not sure how right it is to ask this question, but still here it goes. I have a full 2D environment, with sprites going around as landscape, characters, etc And to make it more state-of-art looking, i want to implement a motion blur effect, similar to modern FPS's (i.e. crysis) blur when moving fast the camera. In a sidescroller, the desired effect is having this slight blur appearing to give the idea of fast movement, when the camera is moving. If anyone could give me some tips on doing this, im assuming in a pixel shader, i'd be grate. Also, if anyone has other good tips on cool pixel shader effects for 2D games it would be awesome, like some stylizing post fx, such as previous Prince of Persia illustrative style. Thanks

• The actual difference between styesheet in the header and a seperate file

  - by David Knight

  Am wondering if someone can give me an opinion on this. I have always been taught to have all of the CSS in a separate file that is referenced from the head of the page. Reading this article http://www.lukew.com/ff/entry.asp?1792 the author is talking about making the Guardian website responsive. One of the things he notes they did to make the site faster and more resilient is to add the CSS inline into the header, thus reducing HTTP requests. Now this got me thinking about the right/best/fastest way of using the CSS If you have one main CSS file, its going to be called and read by the site on every page, no mater how big it is. So with that in mind, Im actually starting to think its better to just inline the whole style sheet and remove one HTTP roundtrip. I know for the purposes of neatness and being able to edit the file a seperate file is better. But which would you recommend and which do you think is faster? Thanks!

• Who owns code if its written by one person with another person directing [on hold]

  - by user136226

  I have an Issue that I need some info on. Basically what Im looking to find out is if I create software,and someone else gives me direction on what they want the software to look like,e.g. an image here,this font of text and it must behave in a certain way. Also some of the code was not developed on my computer and there is no official agreement in place. Not looking to screw anyone over here but need to protect myself if things go sour. Do I own the software or is it jointly owned? Thanks

• Tired of windows. How Can Switch to Ubuntu ?

  - by Noah

  Im thinking strongly about starting to use Ubuntu. I am tired of windows and how every computer i get/have runs with it. I'm not real good with computers, but I'm good enough for my needs. Ive used Ubuntu in the past of a friends computer and always pretty impressed with what he could make it do, look like, and the fact that was able to run windows along with it. His computer never crashed or got viruses. That sounds like something i could get used to. Id like to here what some of you think.Also I keep reading about a live cd that allows you to run Ubuntu with windows to basically try it and not have to commit. If so how can I get that. i havent been able to find it anywhere.

• Admin form that generates an email confirmation ends up in SPAM [duplicate]

  - by PJD Creative

  This question already has an answer here: How can I prevent my mail from being classified as spam? 10 answers I have an admin form that I have setup for a client, that generates an email confirmation from a template I have designer... It works really well but it ends up in spam some of the time, and this is real frustrating as it is just confirming some details for the customer of what they have just booked, not at all spam, and is accessed via a page where the admin requires login. Any suggestions as to why this may end up in spam. It does have dollar signs ($$) as it is confirming a price, im assuming this is one problem, the rest of it is just general dates and info about the confirmation. Is there any suggestions on how to get this out of spam? thanks in advance

• OpenGL Learning Material (that's up to date)

  - by Sauron

  So im sure there are topics on this, but alot of them list older material. And the last book: http://www.amazon.com/OpenGL-SuperBible-Comprehensive-Tutorial-Reference/dp/0321712617/ref=sr_1_1?ie=UTF8&qid=1346116133&sr=8-1&keywords=opengl REALLY REALLY disappointed me. I DO NOT want to use someone else's library to learn this stuff, that bothers me SOOO much. So I was hoping there was a newer book that goes into detail, and doesn't use some sort of library "Hiding" everything from you. Or should I just look at older material? If so....anything thats not "too" out of date. Terrain tutorials are a plus (that's kinda my "goal"). Thanks
