  • 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.

  • Network sharing for android

    - by Shagun
    I am on ubuntu 12.04 and I want to create a wifi hotspot to be used with my android device. Now I know there are so many tutorials available every where and that I have all options in network tab to use but I couldn't get it to work. Android does not work with an adhoc connection and whatever wifi network I created, my android device could not connect to it (I could connect a phone using bada to it and other computers can also be connected) I know the work around to get android on a adhoc connection but can't I have some thing as simple as connectify for windows? PS : I am not looking for workarounds involving android.

  • How do I get a D-Link DWL-G520 working?

    - by human33
    I have Ubuntu 12.04 on an older desktop PC, and I am finding it much harder to connect to a wifi connection than it should be. I have an iPhone with which I want to tether to it with Mifi 4.0, but I need to install ipheth which I can't do without internet on that computer. I am typing from my other windows pc with which i can download and move hings with thumb drives, but haven't gotten keryx to work. I also found a D-Link DWL-G520 HIGH SPEED 2.4GHZ (802.11G) WIRELESS 108MBPS PCI ADAPTER which I installed, but can't find a driver to put on a flashdrive to use it. If anybody has any ideas, they are appreciated. I am a noob, and I don't want to have to move the comp. downstairs to plug into the modem. PS: I also have a netgear USB network adapter, which doesn't work with my Ubuntu.

  • Do subdomains need to be defined through domain registrar?

    - by Johnny
    I have bought a new domain name from GoDaddy. Let's say it is abcd.com. On GoDaddy's DNS Managing page, I changed A(Host) part to @ = 74.125.232.215 which is www.google.co.uk's IP address. Now if I type www.abcd.com, it directly goes to www.google.co.uk. But if I type http://test.abcd.com, it cannot be loaded. Do I need to define every subdomain through GoDaddy? Is this how it works? P.S. Amazon EC2 directly generates a subdomain for users to reach their virtual PCs. It cannot be domain registrar dependant. P.S.2. Same question for using "www2" at the start of url.

  • Google doesn't index a subdomain. What can be the problem and what can be done?

    - by fudge
    Hi! I have a domain, let's call it example.com, which has a subdomain, games.example.com. I maintain a games forum using phpbbseo which is located at games.example.com/forum. The problem is that the forum is not being crawled. I used Google's webmaster tools and tested that the page is seen by google. P.S. There is a link from games.example.com to games.example.com/forum. What can I do? How can I make google crawl my forum?

  • dig @server doesn't work

    - by JustTrying
    I have Ubuntu 12.04 with BIND9, working just as a caching server (forwarding to 8.8.8.8). When I use, for example, dig +norecurse @l.root-servers.net www.uniroma1.it, I obtain the following output ; << DiG 9.8.1-P1 << +norecurse @l.root-servers.net www.uniroma1.it ; (1 server found) ;; global options: +cmd ;; connection timed out; no servers could be reached Using Wireshark I discovered that the outgoing queries are correct, but there aren't any incoming answers. Why? P.S. Using simply dig www.uniroma1.it I obtain the correct answers.

  • Solving programming problems or contributing code?

    - by nischayn22
    What are the best skills to develop for a college graduate?? Should one spend hours/days trying to solve problems on codechef or topcoder or contribute code to open source organizations? My personal experience says solving problems teaches you how to make optimal code and learn new programming techniques (which someone else has researched and made available) to solve problems, whereas contributing to open source teaches you how to organize code (so others can work on it), use coding conventions and make "real" use of what you have learnt so far, blah blah!! Also another thing to note is that many companies are hiring today based on one's problem solving skills (Is this something I should worry about?) P.S. I have done little of online problem solving and little of code contribution (via GSoC), but left confused what I should continue doing (as doing both simultaneously isn't easy).

  • After some wired flash out, I can't login to wmii any more, how to fix it?

    - by Zen
    I've been using wmii on Ubuntu14.04(virtual machine on win7) for months. During which, I got pop out to login interface servaral times due to some wired mouse click action. But today, after I met such wired pop out, I can't login to wmii any more. I'll be stuck at the interface like The bottom yellow bar is the command area for wmii. but it has no response when I press Mod + p I restart my machine, and even reinstalled wmii, but everytime when I tried to login wmii, I stuck at that interface. By the way, I login to wmii from the login interface, where I can choose between Gnome and wmii. How to fix this? I'm crying for help! ps: I can login to gnome normally

  • 13.04 - Extenal monitor plugged on laptop HDMI shows image but lags a lot

    - by Thiago Fassina
    It uses an Nvidia GeForce GTS 250M. When I plug in the monitor, it shows some images but with bad FPS and lagging a lot. For example, when I move the mouse pointer, it leaves a trail that vanishes from time to time. I didn't install Nvidia drivers because every time I did this on past versions I ended up with an unbootable system. On past versions I just gave up trying to use the monitor cause it never showed anything regardless of what driver I installed. But since 13.04 ALMOST made it, I'll make another tries. ps.: Works perfectlty on Windows 7/8

  • Generating AdSense ad impression?

    - by Danny
    I owned two website. Let's say as example www.first.com and www.second.com. I have two apps in Google chrome-store whose app URL is: app1 URL = www.first.com/currency_converter.php app2 URL = www.first.com/currency_converter.php respectively. Currently if user lunch/click on first app URL then I am forwarding them to my first website homepage (www.first.com), where I have AdSense code with currency converter app. In this way I am generating Google ad impression and traffic for my first website (i.e www.first.com). So is this valid way? Does I am violating any Google AdSense rule? Please provide your reply or suggestions. P.S.: Please comment, if my question is not clear, I will try to write it in some other way.

  • What are the factors that determine the default frequency of a shader call?

    - by user827992
    After i have been played for some days with various vertex and fragments shaders seems clear to me that this programs are called by the GPU at every and each rendering cycle, the problem is that I can't really quantify this frequency and I can't tell if is based on some default values or not because I don't have a big collection of hardware right now to do extensive tests. For what i know the answer could be really trivial like "it's the same of the refresh rate of your monitor", but i would like some good answers on that to be clear on this. For instance looks really odd to me that all the techniques used to control the amount of FPS that i have seen until now uses a call for the OpenGL function glutGet(GLUT_ELAPSED_TIME) to retrieve a value in ms about when the rendering started but I have to relies on the CPU to do the math. Why I can't set an FPS value in OpenGL if OpenGL clearly has a counter and a timer/clock? PS I'm referring to OpenGL 3.0+

  • Pendrive USB Ubuntu installation - black screen on boot

    - by ubuntico
    I see many posts on this, but no solution. I installed Ubuntu 12.04 on my 16GB USB flash drive using this official link using their tool Universal USB Installer. Installation to USB went fine so I set my laptop to boot from USB and the Ubuntu was recognized. I saw the usual boot screen and I chose option "Run Ubuntu from this USB". The boot process started and after 5-6 seconds the screen goes black and non-responsive. I thought that it hang on X loading so I tried switching to console via Ctrl+Alt+F1-6 but the system did not respond. Why is this happening? Am I doing something wrong? PS. My laptop is HP Pavillion G6

  • how to deal with parallel programming

    - by nkint
    Hi. I know that parallel programming is a big resource in computer graphics, with moder machines, and mayebe a computing model that will be grow up in the near future (is this trend true?). I want to know what is the best way to deal with it. there is some practical general purpose usefulness in studying processor n-dimensional mesh, or bitonic sort in p-ram machines or it's only theory for domain specific hardware used in real particular signal elaborations of scientific simulations? Is this the best way to acquire the know how for how to become acquainted with cuda or opencl? (i'm interested in computer graphics applications) and why functional programming is so important to understand parallel computing? ps: as someone has advice me i have forked this discussion from http://stackoverflow.com/questions/4908677/how-to-deal-with-parallel-programming

  • Is medium-resolution a good middle ground for web images?

    - by ColdSharper
    I'm used to thinking of hi-res 300 ppi and above, and lo-res, 72 or 96. But today I got an image that was 240 ppi, and da boss wanted as high res as possible. It was a huge file, but when I resized down to 700px wide in PS, optimized jpeg with no compression, without changing the res the result was a 129KB file that looks decent on most browsers (at least my box...who knows about old monitors, etc.) Did I miss a conference when I was on a break? Are others doing medium-res?

  • Java dev learning Python: what concepts do I need to wrap my head around?

    - by LRE
    I've run through a few tutorials and written some small projects. I'm right in the middle of a small project now infact. All is going well enough thanks in no small part to Uncle Google (who usually points me to Stackoverflow ;-) Several times in the last few days I've found myself wondering "what am I missing?" - I feel that I'm still thinking in Java as I write in Python. This question over at StackOverflow is full of tips about what resources to read up on for learning Python, but I still feel that I'm a Java dev with a dictionary (no pun intended) to translate into Python. What I really want to do is refactor my head to be able to write Pythonic Python instead of Java disguised as Python (not that I want to loose my Java skills). So, the crux of my question is: what concepts does a Java dev really need to learn to think Pythonic? This includes anything that needs to be un-learnt. ps: I consider language syntax to not be particularly relevant to this question.

  • wired connection not being recognised in ubuntu 10.04 lts

    - by arun
    I have windows7 installed on my C drive and ubuntu 10.04 lts on my D drive. When I plud the lan cable (ethernet cable) onto the ethernet card of my laptop, windows7 identifies the network correctly without the need for any manual settings and connects me to the network correctly. Unfortunately, in ubuntu, even after plugging in the cable, nothing happens (on the network side). It is only scanning for wireless networks it seems, and doesnt bother about the wired networks. I tried adding a new wired connection and manually entered the physical address which was displayed when i connected to the network using windows. i entered the phy address, and told it to use auto dhcp and saved the dialog bog in ubuntu network connection. Still there is no change, and ubuntu doesnt seem to recognise anything. please let me know how to work with wired connections using ubuntu, and why my wired cable is not being recognized in ubuntu. thanks. PS: I am pretty new to ubuntu/ linux :)

  • Why is (Ogg) Vorbis not automatically supported by Windows?

    - by flying sheep
    Vorbis was never threatened by MPEG LA, so it is undoubtedly completely patent free. (MPEG LA never misses a chance to spread patent FUD) Windows supports mp3, so it isn’t because they want to push their crappy wma. The GPL allows distribution alongside commercial products, and Even if they fear to ship GPL software, they can still load it automatically, like they do with XviD So why can’t a windows customer not simply drop a ogg vorbis file into his/her music library and listen to it via WMP? PS: To counter misconceptions: They already download the GPL’d XviD codec on demand, so they already have 99% of what it takes to do the same with Vorbis. It would take me about 5 minutes to do this, if I were familiar with the WMP code base and directshow filter system. PSS: I was told to ask this here rather than on stackoverflow, so i do.

  • Design: How to model / where to store relational data between classes

    - by Walker
    I'm trying to figure out the best design here, and I can see multiple approaches, but none that seems "right." There are three relevant classes here: Base, TradingPost, and Resource. Each Base has a TradingPost which can offer various Resources depending on the Base's tech level. Where is the right place to store the minimum tech level a base must possess to offer any given resource? A database seems like overkill. Putting it in each subclass of Resource seems wrong--that's not an intrinsic property of the Resource. Do I have a mediating class, and if so, how does it work? It's important that I not be duplicating code; that I have one place where I set the required tech level for a given item. Essentially, where does this data belong? P.S. Feel free to change the title; I struggled to come up with one that fits.

  • Do you enjoy 'Unit testing' ? [closed]

    - by jibin
    Possible Duplicate: How have you made unit testing more enjoyable ? i mean we all are developers & we love coding.I love learning new stuff(languages, frameworks, even new domains like mobile/Tablet development). But Testing ? As a newbie to the corporate environment,I just can't digest it.(We follow 'write-then-manually-test pattern').is it unit testing ?.Usually a single developer handles a module(From design to code & unit testing).So is it practical ? Somebody tell me how to make unit testing fun ? Or just How to do it properly?Do we try all possibilities manually.Say unit test for a webpage with lot of 'javascript validations'. PS:projects are all web applications.

  • easy visualization of usage statistics (web app)

    - by sova
    I have some usage queries for my web app's database, the results of which I want to display graphically. Is there an easy-to-use api that exists for this purpose? I want to show things like average query-time per user (a small user-base), average query time per day, and things like that. I think it would be cool to show these on a two-axis graph. I am displaying this data on my site, so a jQuery/javascript/html solution for rendering information into graphs would be ideal. Thank you :) P.S. I wasn't sure if I should ask this on SO, but I am looking more for which product to use, not how to program with it.

  • How to script a reinstall (apt repo's and installed packages)

    - by Kurtosis
    I need to wipe my hard drive and reinstall Ubuntu. /home is on a separate partition, so I can back that up to a backup drive, then copy it back to the wiped drive, install ubuntu, and point it at the existing /home, no problem. However, I also want to script a reinstall of all my apt repo's and the packages I currently have installed, so I don't have to waste hours doing that manually. Anyone know a good way to do this? PS - At least, I'm pretty sure I have to wipe the drive. Need to install Windows 7, and only have an HP system restore disk that formats the whole drive, and not a legit Windows 7 install disk that lets me install on a single partition. If somebody know a way to trick the system restore disk to install only to a single partition, I'd love to hear it.

  • Dash doesn't recognize that application is installed

    - by Calixte
    I've installed Geary from the software center, but I can't launch it from the Dash nor did I manage to create an app icon on the Launcher. The Software center has no problem seeing that the app is installed (see screenshot) Running the command "geary" will launch the app. Is there any way I can force the Dash to function properly? Thanks, Calixte PS: Does anyone know what this problem is related to? I tried re-installing the app and restarting the computer but that has no effect at all. I have practically installed nothing on this computer, so I can't imagine what app could interfere with the Dash
