• video/audio output via HDMI Ubuntu 12.04

  - by lostNfound

  I've been out of the Ubuntu loop for quite a while now and have a completely new laptop now. Just installed Ubuntu 12.04 64-bit and would like to output my video and my audio via HDMI to my television. the following is the lspci | grep VGA for my computer. please tell me if there is any additional information needed and preferably how to obtain it and i will be more than happy to oblige. thank you in advance for your time and assistance in this matter. 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GF108 [GeForce GT 540M] (rev a1) Edit: every time i restart my computer, after a short moment, i get an error message stating something along the lines "sorry, jockey needed to close unexpectedly." after researching, i discovered jockey is the name of the "additional drivers," which after initial installation, ubuntu informed me of proprietary drivers available. those are no longer available, and this error continues to occur.

• Problem creating levels using inherited classes/polymorphism

  - by Adam

  I'm trying to write my level classes by having a base class that each level class inherits from...The base class uses pure virtual functions. My base class is only going to be used as a vector that'll have the inherited level classes pushed onto it...This is what my code looks like at the moment, I've tried various things and get the same result (segmentation fault). //level.h class Level { protected: Mix_Music *music; SDL_Surface *background; SDL_Surface *background2; vector<Enemy> enemy; bool loaded; int time; public: Level(); virtual ~Level(); int bgX, bgY; int bg2X, bg2Y; int width, height; virtual void load(); virtual void unload(); virtual void update(); virtual void draw(); }; //level.cpp Level::Level() { bgX = 0; bgY = 0; bg2X = 0; bg2Y = 0; width = 2048; height = 480; loaded = false; time = 0; } Level::~Level() { } //virtual functions are empty... I'm not sure exactly what I'm supposed to include in the inherited class structure, but this is what I have at the moment... //level1.h class Level1: public Level { public: Level1(); ~Level1(); void load(); void unload(); void update(); void draw(); }; //level1.cpp Level1::Level1() { } Level1::~Level1() { enemy.clear(); Mix_FreeMusic(music); SDL_FreeSurface(background); SDL_FreeSurface(background2); music = NULL; background = NULL; background2 = NULL; Mix_CloseAudio(); } void Level1::load() { music = Mix_LoadMUS("music/song1.xm"); background = loadImage("image/background.png"); background2 = loadImage("image/background2.png"); Mix_OpenAudio(48000, MIX_DEFAULT_FORMAT, 2, 4096); Mix_PlayMusic(music, -1); } void Level1::unload() { } //functions have level-specific code in them... Right now for testing purposes, I just have the main loop call Level1 level1; and use the functions, but when I run the game I get a segmentation fault. This is the first time I've tried writing inherited classes, so I know I'm doing something wrong, but I can't seem to figure out what exactly.

• How to play many sounds at once in OpenAL

  - by Krom Stern

  I'm developing an RTS game and I would like to add sounds to it. My choice has landed on OpenAL. I have plenty of units which from time to time make sounds: fSound.Play(sfx_shoot, location). Sounds often repeat, e.g. when squad of archers shoots arrows, but they are not synced with each other. My questions are: What is the common design pattern to play multiple sounds in OpenAL, when some of them are duplicate? What are the hardware limitations on sounds count and tricks to overcome them?

• Connecting a reliance zte AC2737 netconnect + modem

  - by coditor

  I have a Reliance netconnect+ zte Ac2737. It has an allocated data of 5gb per month. The modem works fine only after the allocated data is over, for which i have to pay extra to the provider. I tried contacting the provider, but it was not of much help. The system detects the modem every time. I assume that it must be a possible problem with the provider, so is there any chance it is the problem of Ubuntu 12.04 LTS 64 bit itself as i have no other reason to think otherwise an it works fine every time on windows.

• How to write efficient code despite heavy deadlines

  - by gladysbixly

  I am working in an environment wherein we have many projects with strict deadlines on deliverables. We even talk directly to the clients so getting the jobs done and fast is a must. My issue is that i'd always write code for the first solution that comes to my mind, which of course I thought as best at that moment. It always ends up ugly though and i'd later realize that there are better ways to do it but can't afford to change due to time restrictions. Are there any tips by which I could make my code efficient yet deliver on time?

• Long term planning and agile?

  - by Ignite

  My team has recently went through the process of laying out a nearly one year plan for our direction of work. We have separated the plan into three phases and each phase will include a couple of launches. I wonder, from an agile point of you, is what we do wrong? I think it's not a bad idea, because we haven't spent too much time on designing anything but the first few steps and it's possible for us to change direction. At the same time it's nice that we don't act with only the near term in sight.

• How to render a retro-like pixel graphics from 3d models?

  - by momijigari

  I was wondering if there's a possibility to render a retro-pixel-like graphics from 3d model in real time? I'm talking about the Starfarer-like graphics. I know it's hand drawn, and it's 2d. But if I need a 3d objects with the same aesthetics? I'm currently working with Flash. But I don't need any ready-solutions, I just want to understand the principle from any other platform if there is one. So if anybody met anything like this I would appreciate your help. (If it's not possible to do in real time, I could at least pre-render a sequence of sprites. It would be much better than creating hundreds of hand-drawn ones)

• Abandoment to blame?

  - by Larsenal

  I have a code snippet for an app that users are loading as a 3rd party script on their site. The general sequence is as follows: Site loads "http://www.example.com/foo.js" foo.js does stuff 1 to 2 seconds later, foo.js loads bar.js Now in a perfect world, I'd want to see matching counts for the calls to foo.js and bar.js. However, bar.js loads only about 94% of the time. I'm wondering how much of this discrepancy might be attributable to site abandonment given the fact that bar.js is delayed by 1 or 2 seconds. I posted here instead of StackOverflow since I think it's more a question about what would be typical time on page when users abandon the page.

• How to loop through a javascript object and check each key exists in a separate multidimensional object

  - by Paul Atkins

  I have 2 javascript objects and I am trying to loop through one object and check whether the key exists in a second multidimensional object going one level deeper each time. Here are the two objects var check = {'scope':'instance', 'item':'body', 'property': 'background'}; var values = {'instance': {'body' : {'background': '000000'}}}; b.map(check, function(key){ console.log(values[key]); }); How am I able to check 1 level deeper in the values object each time? What I am trying to do is check the values object as follows: 1st values['instance'] 2nd values['instance']['body'] 3rd values['instance']['body']['background'] Thanks

• "Best fit" to avoid reuse of object instances in a collection

  - by Simon

  Imagine I have a collection of object instances which represent activities for a user to undertake. Dependent on user attributes, I have to randomly select instances to present activities to the user. For some users, I need to present more activities to them than there are available activities in which case, I want to use the following algorithm. If all available activities have already been presented to the user, then re-select a "used" activity, selecting the earliest presented activity ordered by frequency of use. In other words, try to reduce repetition and where repetition is unavoidable, use the instances which have been repeated less often and were presented furthest back in time. Before I go on to code that algorithm, I wondered if there is some existing pattern I can re-use? [EDIT] "Furthest back in time" is not relevant as I will pass the algorithm an ordered collection of used instances where the first entry is the first presented.

• Why don't smart phones have an auto-forget password feature? [closed]

  - by Kelvin

  Storing passwords to external services (e.g. corporate email servers) on smart phones is very insecure, since phones are more easily stolen. Has any vendor implemented a feature to only cache a password in memory for a limited amount of time? After the time period has elapsed, the app would ask for the password again. EDIT: I should've clarified - I'm aware that many (most?) users are lazy and want to just "set it and forget it". The always-remember feature will probably always be present. I was curious about an option to enable auto-forget for the security-conscious.

• Did You Know Facebook Has Built-In Shortcut Keys?

  I was spending some time browsing around Facebook today (translation: wasting time), when I noticed that they have some shortcut keys for navigating around the site using the keyboard, so I put together a list for everybody. Note: for each of these shortcut keys, if you’re using Firefox, you’ll need to use Shift+Alt instead of just Alt, and for Internet Explorer you’ll need to hit the Enter key after the shortcut to trigger it.

• Next steps for Asp.Net C# developer (RoR vs Python Django vs PhP Drupal)

  - by ProfessorB

  A majority of my web development experience has been on the .Net stack (mainly Asp.net C#). I am looking to learn something new in my spare time, for the use of personal projects and possibly for use professionally (as an ISV). I know some Python, done some scripting with it in the past, nothing on the web though. Php has been around for a long time and RoR has gained a lot of popularity. Are there any developers from the .NET world that have migrated over to one or more of the other platforms? If so, which do you prefer and why? Which would you suggest and why?

• Problem with keyboard and trackpad on ubuntu 12.04

  - by Cdub

  Have a really strange issue with my keyboard and trackpad after installing ubuntu 12.04. It picked up both fine with the livecd and in the install, but for quite awhile now, I find when I power my laptop up (Toshiba Satellite L775D-S7132), when I hit the login screen much of the time I won't have any keyboard or touchpad. I can plug in a usb mouse and then at least restart or shut the laptop down and then keep trying until it picks it up correctly, but it's really a pain to have to do that all the time. Are there quite a few bugs related to keyboard and trackpad issues with the new version? I really want to get this issue resolved as it's a major nuisance. Otherwise, my hardware gets picked up fine. Video, audio, wlan, usb work perfectly and I don't ever have any issues with them. What's the best way to figure out the problem? Thanks in advance, C.

• The ETL from Hell - Diagnosing Batch System Performance Issues

  Too often, the batch systems that underlie a lot of database processing just grow without conscious design.

• Dashboard to aggregate Google Analytics, Facebook, YouTube etc tracking data?

  - by Richard

  I'd like to see as much tracking data as possible about my online presence, in one single dashboard - so views/conversions from Google Analytics data, the performance of my Facebook campaigns via the Insights API, views/clicks from my YouTube campaigns, etc. This could be as simple as a graph with time on the x-axis, and key indicators from each source on the y-axis (conversions from Analytics, likes on Facebook, views on YouTube, etc). The idea is that I can see customer engagement with each source, over time. I can write my own such dashboard easily enough, but I wondered if there was something off-the-shelf that already did this. Apologies if this isn't the right forum for such a question - would appreciate tips for the best place to ask.

• Number Game Algorithm

  - by 7Aces

  Problem Link - http://www.iarcs.org.in/inoi/2011/zco2011/zco2011-1b.php The task is to find the maximum score you can get in the game. Such problems, based on games, where you have to simulate, predict the result, or obtain the maximum possible score always seem to puzzle me. I can do it with recursion by considering two cases - first number picked or last number picked, each of which again branches into two states similarly, and so on... which finally can yield the max possible result. But it's a very time-inefficient approach, since time increases exponentially, due to the large test cases. What is the most pragmatic approach to the problem, and to such problems in general?
