  • Any learning/studying material for C/C++ that use game programming as learning context out there?

    - by mac
    As most of game programming is done - I read on this very site - in C/C++ I was wondering if there is any learning/studying material for C/C++ that would target specifically game programming. I am not looking for material about "developing games" or "software architecture for games", but rather for material that uses "game programming" as the CONTEXT for introducing and illustrating C/C++ features, idioms, programming techniques, etc... With a simile: think to the GOF book on design patterns. There, they used "developing a text-editor" as a context for introducing design patterns, but the book is most definitively not a book about "developing text-editors". Thanks in advance for your time and advice! PS: My background: I am a programmer with a solid experience in OO scripting languages and only some experience in C and Assembler (on AVR microcontrollers), so I am thinking to mid-to-advanced level material, rather than tutorials for beginners, although it might be interesting to take a look to the latter ones if nothing else is available.

  • Configuring Compiz Grid?

    - by Alec
    Disclaimer: I'm three days into Ubuntu, and am loving it so far. Except for this one thing. Apparently there is a way to get an 'Areo Snap' feature with the Grid Plugin for Compiz. I've downloaded the advanced configuration files and have selected the plugin in the Compiz Configuration - even re-mapped the keys because I don't have a numpad. Regardless of what I do, I can't get it to work, either by dragging the windows or using the assigned keys. Is there something I need to do in addition to these things? Am I simply missing something?

  • How to store bitmaps in memory?

    - by Geotarget
    I'm working with general purpose image rendering, and high-performance image processing, and so I need to know how to store bitmaps in-memory. (24bpp/32bpp, compressed/raw, etc) I'm not working with 3D graphics or DirectX / OpenGL rendering and so I don't need to use graphics card compatible bitmap formats. My questions: What is the "usual" or "normal" way to store bitmaps in memory? (in C++ engines/projects?) How to store bitmaps for high-performance algorithms, such that read/write times are the fastest? (fixed array? with/without padding? 24-bpp or 32-bpp?) How to store bitmaps for applications handling a lot of bitmap data, to minimize memory usage? (JPEG? or a faster [de]compression algorithm?) Some possible methods: Use a fixed packed 24-bpp or 32-bpp int[] array and simply access pixels using pointer access, all pixels are allocated in one continuous memory chunk (could be 1-10 MB) Use a form of "sparse" data storage so each line of the bitmap is allocated separately, reusing more memory and requiring smaller contiguous memory segments Store bitmaps in its compressed form (PNG, JPG, GIF, etc) and unpack only when its needed, reducing the amount of memory used. Delete the unpacked data if its not used for 10 secs.

  • Why did visual programming never take off and what future paradigms might change that?

    - by Rego
    As the number of "visual" OS's such as Android, iOS and the promised Windows 8 are becoming more popular, it does not seem to me that we programmers have new ways to code using these new technologies, due to a possible lack in new visual programming languages paradigms. I've seen several discussions about incompatibilities between the current coding development environment, and the new OS approaches from Windows 8, Android and other tablets OS's. I mean, today if we have a new tablet, it's almost a requirement for coding, to have, for instance, an external keyboard (due it seems to me it's very difficult to program using the touch screen), exactly because the coding assistance is not conceived to "write" thousands of lines of code. So, how advanced should be the "new" visual programming languages paradigms? Which characteristics these new paradigms would be required?

  • How To Get a Better Wireless Signal and Reduce Wireless Network Interference

    - by Chris Hoffman
    Like all sufficiently advanced technologies, Wi-Fi can feel like magic. But Wi-Fi isn’t magic – it’s radio waves. A variety of things can interfere with these radio waves, making your wireless connection weaker and more unreliable. The main keys to improving your wireless network’s signal are positioning your router properly — taking obstructions into account — and reducing interference from other wireless networks and household appliances.

    This is what advanced settings tell me: Shell Laptop lid close action on battery suspend Shell Laptop lid close action when on AC suspend I couldn't post a screenshot because "new users aren't allowed to post images. Earn more than 10 reputation to post images" The screen is on when I open the lid after closing for a few seconds. But not when I suspend from the session menu. Still the battery on my Dell inspiron N5110 is always empty when I get back to it after closing the lid. 'Why' is my question.

  • Targeting .Net framework version 3.0. (4 replies)

  • Ubuntu One, compressed files

    - by user8179
    I have uploaded some files to my Ubuntu One account and it seems to work great most of the time. I usually upload them directly from Nautilus by right clicking the folder, using the ”Synchronize this folder” option, and then I make sure that the file I want to upload is published. Then I usually test the whole thing by trying to download it. I right click the file again to get its URL and I paste it into my Web browser. This usually works fine. But yesterday I uploaded two compressed files – ”.tar.bz2”. When I tried to open them after downloading them with my Web browser (Opera), it failed. I found that the file was bigger than the original file (2358 B instead af 2335 B – 15 B added at the beginning of the file and 8 B added to the end), and someone at the Opera channel (IRC) at OperaNet (Europe) figured out that the reason for this is that the server compress the file again, ”without telling Opera”. So to be able to extract the file I need to add ”.gz” to the file name and then extract it twice. If I downloaded it with Firefox however, I didn't need to do that, so maybe Firefox figured this out somehow in a way that Opera does not. Someone also tried to download the file with wget and some other browser and he also got the same result as I did with Opera, that is the file is compressed a second time by the server. I guess ”the server” is the Ubuntu One server, right? So why is this? Could it be done better somehow? Or did I do something wrong when uploading the files? It also seems like this extra compressing thing does not always happen, because when I tried again a few minutes ago, the file came down with its right size (2335 B), without an extra compression. But the other file (114 MiB) was still compressed twice.

  • Pidgin unable to connect to GTalk

    - by user42933
    I can't believe I'm raising this question after years, but after a fresh installation of Ubuntu 12.10, I'm unable to connect Pidgin to Google Talk. I use a Google Apps domain name, and the settings that I'm using are : Protocol : XMPP Username : **** Domain : ********.com Resource : Home In the advanced tab, Connection security : Require encryption. UNCHECK Allow plaintext auth over unencrypted steams Connect port : 5222 Connect sever : talk.google.com File transfer proxies : proxy.eu.jabber.org Bosh URL : (blank) In the proxy tab, No proxy. I had used these same settings on 12.04 and it had worked like a charm. Any help will be appreciated.

  • Skynet Big Data Demo Using Hexbug Spider Robot, Raspberry Pi, and Java SE Embedded (Part 4)

    - by hinkmond
    Here's the first sign of life of a Hexbug Spider Robot converted to become a Skynet Big Data model T-1. Yes, this is T-1 the precursor to the Cyberdyne Systems T-101 (and you know where that will lead to...) It is demonstrating a heartbeat using a simple Java SE Embedded program to drive it. See: Skynet Model T-1 Heartbeat It's alive!!! Well, almost alive. At least there's a pulse. We'll program more to its actions next, and then finally connect it to Skynet Big Data to do more advanced stuff, like hunt for Sara Connor. Java SE Embedded programming makes it simple to create the first model in the long line of T-XXX robots to take on the world. Raspberry Pi makes connecting it all together on one simple device, easy. Next post, I'll show how the wires are connected to drive the T-1 robot. Hinkmond

  • Sortable Accordion Modified to Implement More On Click However New Levels Will Not Expand

    - by Tim Marshall
    JS Fiddle: http://jsfiddle.net/JF7PD/ I've been doing extensive work on this and I've just able almost got it fully working. The reason why I am asking for help now is that I don't have a clue why my newly added accordion(s) do not expand upon being clicked. I've got a feeling it may be due to the newly added code as I was having problems using my code in the file so instead I looked at the source and copied the accordion level to be used and all appears to look fine apart from them not expanding. Thank you for any help in advanced, Best Regards, Tim

    I'm using Ubuntu and I'm trying to connect to another machine in a different network using remote desktop. In Windows7 I have made the following in order to activate remote desktop: I've gone to computer - properties - remote settings I've selected the option: "Allow connections from computers running any version of Remote Desktop I've opened "Windows Firewall with Advanced Security" In inbound rules I've enabled the rules for remote desktop (public and domain) I have also installed Remmina in the Ubuntu machine. For configuring it I did the following steps: Selected the RDP protocol In the server input I have written the Windows machine public IP. In username / password I have typed my login credentials (the same as my Windows admin account) But when I try to connect I get this error message: "Unable to connect to RDP server 89.130.251.160" If I ping my Windows7 machine, I have a correct response.

  • How to attend one off lectures? [closed]

    - by Senthil Kumaran
    Many times, we come across one-off lectures from famous Computer Scientists. Last year, I came across one by Ms. Barbara Liskov, but I could not go because the University Hall was bit far. Tomorrow, there is one by Dr. Knuth! Now the problem I am facing is, "I don't know much about the material he is going to talk", so I am not sure if I should plan and I fear it will be like going for a "temple". :) What is your advise and general strategy that you have followed whenever you wanted to attend a talk or lecture wherein, it may have been worthwhile if it were an introductory tutorial, but instead you were sitting in an advanced 1 hour lecture by a famous scientist.

  • A simple deployment example using Oracle Solaris 11

    - by Glynn Foster
    Last week I was over in Melbourne and Sydney to present at an Oracle Technology Network System Administration Day. During a set of morning sessions, I presented on some of the new things that we've done in Oracle Solaris 11 and our focus for the future. One of the sessions I presented was giving a quick technical overview of what a typical application deployment scenario would look like using technologies like the Image Packaging System (IPS), Service Management Facility (SMF), Oracle Solaris Zones, and network virtualization. While it's just a simple example, it provides the basic building blocks for a more advanced configuration that a data center would typically deploy. Given these would likely be of general interest, I thought I'd upload the slides for others to view - enjoy! You can download the original source PPTX without some of the formatting errors in the above.

  • How to package static content outside of web application?

    - by chinto
    Our web application has static content packaged as part of WAR. We have been planning to move it out of the project and host it directly on Apache to achieve the following objectives. It's getting too big and bloating the EAR size resulting in slower deployment across nodes. Faster deployment times. Take the load of Application Server Host the static content on a sub domain allowing some browsers (IE) to load resources simultaneously Give us an option to use further caching such as Apache mod_cache apart from the cache headers we send out to browsers. We use yuicompressor-maven-plugin to aggregate and minimize JS file. My question is how do package and manage this static content out side of the web application? My current options are. New maven war project. Still use the same plugin for aggregation and compression. Just a plain directory in SVN and use YUI/Google compressor directly. Or is there a better technology out there to manage static content as a project?

  • Announcing the ADF Architecture Square at OOW12

    - by Chris Muir
    The ADF product management team are happy to announce at Oracle Open World the publication of the ADF Architecture Square: Over the last number of years Oracle has recognized that many customers have matured their ADF skills and are now looking for information on advanced concepts beyond the how-do-I-get-this-poplist-to-work type questions.  In order to satisfy this demand we've devised the ADF Architecture Square where papers, presentations and demos will consider such broad software engineering concepts as ADF architecture, development and testing, building and deployment, and infrastructure.   If you have a look at the site right now it's a rather modest affair, but we hope to continue to expand the content to give further guidance and information to help shortcut your ADF project needs.  Either watch the website or follow our dedicated @adfarchsquare twitter feed.
