  • What are good JS libraries for game dev?

    - by acidzombie24
    If I decide to write a simple game both text and graphical (2d) what libraries would I use? (Assume we are using a HTML5 compatible browser) The main things I can think of Rendering text on screen Animating sprites (using images/css) Input (capturing the arrow keys and getting relative mouse positions) Perhaps some preloading resource or dynamically loading resources and choosing order Sound (but I am unsure how important this will be to me at first). Perhaps with mixing and chaining sounds or looping forever until stop. Networking (low priority) to connect a user to another or to continuously GET data without multiple request (I know this exist but I don't know how easy it is to setup or use. But this isn't important to me. Its for the question).

  • What is Cyber Monday? [Infographic]

    - by Jason Fitzpatrick
    Nearly everyone is familiar with Black Friday, the massive shopping day right after Thanksgiving, but Cyber Monday is a recent invention. Check out this infographic for the low down. Cyber Monday is only a scant six years old, an invention of online retailers looking to create a shopping day to compete with the in-store frenzy of Black Friday. Although quite a few retailers offer online Black Friday deals, Cyber Monday is a the biggest day for online deals–many shoppers fail to find the things they were looking for on Black Friday and turn to online sources. You can read more about Cyber Monday here or visit the link below for a higher resolution copy of the infographic. What Is Cyber Monday?

  • Didn't do too well on a Java IKM test, advice?

    - by Jason
    I did an IKM Java test recently and got quite a low score. I only graduated a year ago and I dont have commercial experience in Java (i do web development in my current job). I thought reading up a lot on Java would help me prepare, but when I sat the IKM test i got ripped to pieces. I didn't know much about how the garbage collection actually works, names of other java compilers (i know about javac?), using .dll with Java etc etc. I know a wide range of the basics, but to the extent wether 'int(5L)' produces an integer or not, I really didnt know. My question is that many of the IKM questions I have never come across, yet I have read many of the wider-known Java programming books (Deitel, O'Reilly etc). Am i reading the wrong books??? Could anyone recommend a good plan of action to allow me to go away and self-study and be able to know these really tough java questions?

  • Microsoft and Joyent Announce Node.js Windows Port

    With the Node.js command line tool, developers can type ?node my_app.js.' to run JavaScript programs. It gives developers a JavaScript application programming interface (API) supplies access for the network and file system as well. One instance where Node.js often comes in handy is in the creation of scalable networked programs that emphasize high concurrency and low response times. Developers who wish to use Node.js use on Windows at this time must do so running a virtual machine with Linux.

  • Wireless USB Adapter driver configuration

    - by Jones
    First I would like agree one thing that this is fully for Ubuntu, not for BackTrack. However I'm posting my BackTrack question here since I find similar problems in backtrack forum are being unanswered and Linux/Unix site of StackExchange has very low attraction. I'm having USB wifi adapter (iBall Baton), having chipset RTL8191SU. It displays available wifi networks in Wicd manager. But while trying to connect it gives me bad password. When I'm trying to run airmon-ng it didn't returned me the monitor mode. I tried to replace with Ubuntu 12.10 drivers. But it totally nulled the device functionality. However I restored the drivers. I'm interested to compile drivers as if anyone indicate the methods. Awaiting ideas!

  • ssrs: the report execution has expired or cannot be found

    - by Alex Bransky
    Today I got an exception in a report using SQL Server Reporting Services 2008 R2, but only when attempting to go to the last page of a large report: The report execution sgjahs45wg5vkmi05lq4zaee has expired or cannot be found.;Digging into the logs I found this:library!ReportServer_0-47!149c!12/06/2012-12:37:58:: e ERROR: Throwing Microsoft.ReportingServices.Diagnostics.Utilities.ReportServerStorageException: , An error occurred within the report server database.  This may be due to a connection failure, timeout or low disk condition within the database.;I knew it wasn't a network problem or timeout because I could repeat the problem at will.  I checked the disk space and that seemed fine as well.  The real issue was a lack of memory on the database server that had the ReportServer database.  Restarting the SQL Server engine freed up plenty of RAM and the problem immediately went away.

  • How to make the switch to C++11?

    - by Overv
    I've been programming in C++ for a while now, but mostly thinks centered around the low-level features of C++. By that I mean mostly working with pointers and raw arrays. I think this behavior is known as using C++ as C with classes despite me only having tried C recently for the first time. I was pleasantly surprised how languages like C# and Java hide these details away in convenient standard library classes like Dictionaries and Lists. I'm aware that the C++ standard library has many convenience containers like vectors, maps and strings as well and C++11 only adds to this by having std:: array and ranged loops. How do I best learn to make use of these modern language features and which are suitable for which moments? Is it correct that software engineering in C++ nowadays I'd mostly free of manual memory management? Lastly, which compiler should I use to make the most of the new standard? Visual Studio has excellent debugging tools, but even VS2012 seems to have terrible C++11 support.

  • Software/Hardware Development?

    - by SwarthyMantooth
    Sincere apologies if this is the wrong place to ask this. I am a computer engineering student and I'm currently on my first co-op of the required 5 I have to take, and I've noticed that all I'm really given is software engineering jobs. I love developing software, but I don't want to lose out on the hardware aspect of computers, as having a hybrid knowledge of the two is why I chose this major in the first place. So I guess my question is: Are there any software engineering jobs that still allow you to handle and interface with hardware on a very low level? Or am I to be forced to choose which focus I love more?

  • RPi and Java Embedded GPIO: Connecting LEDs

    - by hinkmond
    Next, we need some low-level peripherals to connect to the Raspberry Pi GPIO header. So, we'll do what's called a "Fry's Run" in Silicon Valley, which means we go shop at the local Fry's Electronics store for parts. In this case, we'll need some breadboard jumper wires (blue wires in photo), some LEDs, and some resistors (for the RPi GPIO, 150 ohms - 300 ohms would work for the 3.3V output of the GPIO ports). And, if you want to do other projects, you might as well by a breadboard, which is a development board with lots of holes in it. Ask a Fry's clerk for help. Or, better yet, ask the customer standing next to you in the electronics components aisle for help. (Might be faster) So, go to your local hobby electronics store, or go to Fry's if you have one close by, and come back here to the next blog post to see how to hook these parts up. Hinkmond

  • How do I convince my boss to come here and see how "good" companies are doing?

    - by Vimvq1987
    My company is bad, I admit it. Inefficient project management, very low quality code, ... I won't get into it. It's partly based on our country's culture, but mostly because our boss is not looking at how good companies are actually going about producing good software/service. I want to bring my boss here, so he can see these things, to convince him to create a better development place for us. How can I do that? Thank you so much. Ps: If I fail to do this, you know, I'm thinking seriously of leaving

  • Splitting up revenue among development team members on Apple's app store

    - by itaiferber
    A friend and I have started developing an app to put on Apple's app store. Development is going fine, but thinking ahead, we're trying to come up with an easy way to share any revenue coming from our efforts. The app store allows you to deposit your revenue into a single bank account, but there's no easy way to split revenue among several people. How do (small) dev teams split up revenue on their products, on, and off the app store? As far as I can tell, banks don't offer an easy way to automatically split the balance on an account 50-50 (or any other percentage, for that matter), especially on a regular basis. So how do teams deal with this? We're not incorporated, and we don't have an official business set up. We're considering depositing all the money into one of our accounts and manually transferring half the money to the other person, but this isn't sustainable over long periods of time. Is there a low-cost, sustainable, automatic process for handling these finances?

  • Future-proofing myself when learning to program.

    - by Chris Bridgett
    I want to learn to program in a 'future-proof' manner, if you like. Whilst Windows dominates the desktop OS marketplace (for now), obviously there is a lot of value in learning its languages/frameworks/API's and so on - this might be subject to change as new devices emerge or Windows shoots itself in the foot (over-friendly previews of Windows 8 don't look too appealing...). Would I be right in thinking that having a solid knowledge of C/C++ for back-end logic/low level programming and the like, combined with an extremely portable language like Java for GUI's and so on, would be a good basis for software development that will prove useful on the most amount of systems? - I'm talking desktop PC's, tablets, phones.

  • How to work with scenes in a 2D game

    - by Anearion
    I'm a java/android programmer, but I don't have any experience in game programming, I'm already reading proper books, like "Pro Android Games", but my concerns are more about the ideas behind game programming than the techniques themselves. I'm working on a 2D game, something like Cluedo to let you understand the genre. I would like to know how should I act with the "scenes", for example, a room with a desk, TV, windows and a lamp. I need to make some items tappable and others not. Is it common to use one image (invisible to the user) with every different item a different color, then call the getColor() method on the image? Or use one image as background, and separate images for all the items? If the latter, how can I set the positioning? and should I use imageView or imageButton? I'm sorry if those are really low quality questions, but as "outsider" ( I'm 23 and still finishing my university ) it's pretty hard learn alone.

  • How to perform a detailed and quick 3D performance test

    - by gsedej
    I am wondering how to quickly test performance of my 3D graphics. Since glxgears is not benchmark what should I use. Also glxgears sometimes stuck at 60FPS, you cannot even compare before/after driver update (e.g. adding xorg-edgers PPA). Even glxgears doesn't really work out of box. One possibility is screensavers, but you can't see FPS. I am also not willing to install 600MB nexuiz, specially if I am running on Live-CD. Other 3D games are also very big... Unigine tests are too demanding for opensource drivers (problems with too low OpenGL and probably texture compression (S3TC...)). I would also like to test OpenGL 2.x extentions. How to quickly test your 3D performance?

  • Track url from Amazon S3 using Google Analytics

    - by morktron
    I couldn't find any decent pay per view video solutions for low budget clients. So I'm considering using a membership extension with Joomla and hosting the video with amazon S3. The only issue is that once someone has signed up to view or download the video if they have any web development experience they will be able to get the url of the video and freely publish it on the web. How can this be prevented? It looks like it can be done using IAM User Temporary Credentials - AWS SDK for PHP but the client would prefer not to have to pay someone to spend hours writing custom php code to get this to work. With Amazon s3 I could at least check the log files I guess to manually monitor the url but is there a way to track the url with Google Analytics? or is there a more elegant solution?

  • Is there a real name policy in the Ubuntu community?

    - by martin001
    I'm not ashamed to be a part of Ubuntu, but I'm trying to keep the number of web search hits for my real name low, which is kinda impossible if you use a Launchpad account. So, I'm wondering if there is a real name policy in the Ubuntu community, or if it's okay to use a pseudonym/nick name/fake name? While it might be okay to use nick names on IRC and in forums, how about these topics: Adding an OpenPGP key to Launchpad. Signing the Ubuntu Code of Conduct. Becoming an Ubuntu member. Code contributions (e.g., signing the Canonical CLA). Thanks in advance for your answers!

  • How can I reply to email by sending a delivery failure message?

    - by wau
    Occasionally, I receive unwanted emails, particularly low-volume spam, or email messages falsely addressed to me (possibly due to typos). I don't want to spend the energy to write a personal message, but I do want to let the sender know that the message never arrived at its destination, and that resending it will be useless. In my opinion, a delivery error message to the sender will fill that need. So, the question is if there is an easy way to send error messages back to the sender. Is there any email client out there which supports sending delivery failure messages as a reply to incoming email -- ideally in one click? (Or, which can be configured to do so?) Alternatively, what is the best way to set up an environment that allows me to send delivery failure messages without too much effort per message sent?

  • Panda 4: Reducing #indexed pages. How much is enough?

    - by Noam
    I've been hit by panda 4 (40% decrease). I didn't see any change during panda 1-3. From what I've read it and when compared to my site, the change is probably due to the fact that I have over 30M pages indexed on Google, and they've starting seeing that as some sort of bad indication. Although I feel all of the pages have a unique value that Google should crawl, it seems I should make some tough calls and deduce the indexed pages according to some prioritization I will conduct. The question is what should be my target, or what factors should help me figure out a relevant target. How many pages should I try to reduce to? - 25M - 15M - 1M - 2000 Is it enough to add noindex to low priority pages or should I also remove all internal linking to them?

  • How do I install Ubuntu on an iMac 27"?

    - by jml
    I have a beautiful 27" iMac. I would like to run Ubuntu on it natively, dual-booting with OS X. I have rEFIt installed, and I can boot into the Ubuntu 10.10 CD, kind of. Here's what happens: I select the CD from the rEFIt menu It loads for a while, then flashes up an aubergine screen with a very low-res picture of a human, an arrow and a keyboard It sits there for a while It changes to 80x25 console mode The screen then goes black, as if nothing is displaying to it All the while, the CD is churning away as if something is reading from it. What do I do?

  • Decrease mouse sensitivity below the standard limit.

    - by Bruce Connor
    I've got a USB mouse attached to my Ubuntu notebook. This mouse is (unfortunately) really sensitive, and so it sometimes gets hard to hit small icons with the mouse pointer. This is really a hardware issue, it's not a bug and it's not Ubuntu's/gnome's fault. Still, I would very much like to this issue through software (solving through hardware would imply buying a new mouse). Back in Windows, if I set the sensitivity as really low it was comfortable enough. In Ubuntu, even the lowest sensitivity and acceleration available (in the SystemPrerencesMouse menu) is still frustrating. How can I decrease it below the default minimum? I tried xset, but it seems xset only deals with acceleration and threshold, but not actual sensitivity.

  • How SQL Saturday could be better

    - by AaronBertrand
    I've been to a lot of SQL Saturdays. They are great events to attend - from a community standpoint, from a learning standpoint, and from a speaker growth standpoint. Who could ask for more, right? Great sessions, from passionate speakers willing to both teach and learn, fantastic networking opportunities and lunch. All for free, or at a very low cost - some events need to recover costs and charge $10 for lunch. Still a phenomenal bargain IMHO. But we all know that these events aren't perfect... there...(read more)
