• Is there any simple C++ code to grab video from UVC webcam and display it simultaneously?

  - by mShero

  I'm very very new to Linux and programming! I'm using ubuntu 11.10 - 64 bits with gcc 4.6.1 I've been searching online for an example C++ code that simply grabs video from a compliant UVC webcam and displays it simultaneously.. I need to compile it on gcc. In OpenCV, it's a very simple code less than 20 lines as I remember! I found this: http://v4l2spec.bytesex.org/spec/capture-example.html But it's very huge code relative to OpenCV code ?! and even when I tried to compile it using gcc.. I got many errors! I copied the code into a cpp file: cap.cpp then wrote in the terminal: gcc cap.cpp -o cap and the errors showed up... same errors with g++ I hope if someone can help me and tell me where can I find another simpler code? and how can I test it ? Thank you :)

• In-memory DB to perform intersects on set slices

  - by IanC

  I have a specific programming need where I need to efficiently store large sorted sets in memory, query them for ranges, and intersect them against other sets that are also queried for ranged. I am looking at Redis, but I can't see a range slice command. MongoDB can only use 1 index, so it has to perform row-level scans, whereas I wish to process using columns that are intersected. I'm also looking at Counchbase, but can't easily determine from the documentation if it is suited to this. I know it uses Memcached, which is AFAIK not suited to this usage. Could anyone share potential solutions for this specific problem? EDIT For example, I need to perform the following: Get the IDs of all cars where the price is between 2000 and 3000, and intersect that will all cars where the engine capacity is between 3000 and 4000.

• Found a better solution to a problem at work - should I deter from posting the code snippet online?

  - by Calmarius

  I think most of us, programmers, used Stack Overflow to solve every day problems: looked for an efficient algorithm to do something. Now imagine a situation: you have a problem to solve. Googled a bit, found a StackOverflow question but you are not really satisfied with the answers so far. So you have to do your own research: you need to do it because you want it in the company's app. Eventually after some hours you have found the better solution. You're happy, you added it to the company's code base, then you want to submit your answer with a code snippet (just several lines) to the question you've found before to help others too. But wait: the company's software is closed source, and you worked on it on the clock. So does this mean I shouldn't post the answer neither at work nor at home to that question in the rest of my life, because I solved it at work, and the company owns that piece of code?

• Huge 2d pixelized world

  - by aspcartman

  I would like to make a game field in a indie-strategic 2d game to be some a-like this popular picture. http://0.static.wix.com/media/6a83ae_cd307e45ffd9c6b145237263ac1a86be.jpg_1024 So every "pixel"(blocks) changes it's color slowly, sometimes a bright color wave happens, etc, but the spaces beetwen this pixels should stay dark (not to count shades, lightning and other 3rd party stuff going on). Units are going to be same "pixelized" and should position them-selfs according those blocks. I have some experience in game-developing, but this task seems not trivial for me. What approaches (shader, tons of sprites or code-render, i don't now) would you recommend me to follow? (I'm thinking of making this game using Unity Engine) Thanks everyone! :)

• Matrix camera, movement concept

  - by NoFace

  I was talking to some guy. He said that my movement concept in game is bad. When left or right arrow is pressed I'm scrolling background what makes you feel that player is moving (player's X remains same). So... he told me something about matrix view. I should create all walls and platforms static and scroll only the camera and move player's rectangle. I did a little research in Google, but nothing found. Can you tell me anything about it? How to start? Maybe links, books and resources? My programming language is Java (2d). Thank you!

• Does Turing-complete implies possibility of malware? [closed]

  - by Mathematician82

  Is it possible to build an operating system that contains some Turing complete compiler (language?) but is unable to run any malware? Or is there any definition for a malware? This question popped on my mind as I was wondering why Windows has more malware than Linux. If Linux contains a C programming language and its compiler, I think it is possible to write a Linux program that works similarly than Windows viruses. But there are less malware for Linux than for Windows although there is a Wine for Linux to simulate Windows programs.

• Desktop in Kubuntu lacks bars and quite everything after trying to apply Plymouth fix for proprietary drivers

  - by Michcioperz

  I'm running Kubuntu 13.10, my computer's graphics card is Nvidia GT 520. I tried to fix that Plymouth's problem with proprietary graphics driver using an old script I found on the internet (it was coded for Natty, now that I think about it I shouldn't have done it). I ran that script and rebooted my computer. First incorrect behaviour I noticed was that Plymouth only displayed its text splash only on 1/4th of the screen, though when I pressed Esc key the logs were displaying correctly. Main problem appeared when I logged in. All my desktop's windows lack menu bar, can't be closed with Alt-F4, and they don't appear on the task bar. I tried fixing it by reinstalling GRUB a few times, purging /etc/grub.d and /boot/grub, but only the text splash issue was fixed. How can I fix that?

• Ruby on rails not popular in big international IT companies?

  - by maro

  I would like to ask you for advice more experienced ROR developers. I am new in programming and like to idea of ROR and I am before the decision on which programing language to specialize Java vs ROR. In the future I wish to learn for bigger international IT companies (IBM, Accenture etc.) but as I am reading their job openings, most of them are hiring Java, C++, .NET... Is the ROR used only in startups or also in bigger companies as well? What should be the reasons of their preference of Java over ROR?

• How to handle situation of programmer stealing credit for your project [on hold]

  - by shorecc

  There is a coworker who has stolen credit for my work. I created a system that will show live statuses of printing machines throughout the plant. There was one glitch in it so the coworker made an improvement and then re-wrote the entire system (copying 90% of my code, yet he added a new piece of hardware then took over the project). Now he asks me programming questions from time to time. I don't mind teaching coworkers how to program, but since he has stolen my ideas and credit in the past I am reluctant to teach him all I know. Today he asks me for a particularly challenging algorithm for this system. His code now looks exactly like the way I would program! How would you handle the situation? How can I decline helping him without appearing to not being a team player?

• I'm a PeopleSoft Developer. Should I learn other languages (C# Java...)?

  - by PSDev

  I've been doing PeopleSoft development for 2 years. Recently, I want to relocate and find out there are not that many PeopleSoft development out there. 90% of the vacant positions are contract type of jobs. I'd rather get a full time permanent position. In PS, I do a lot of maintenance rather than new programming. It does get very boring. Also, I'm not sure if Oracle will one day pull off the plug for PS. What language is in most demand and also offers above average salary? Is it C#, Java, Python, Perl, ...? Thanks.

• Ubuntu 12.04 x64 - Very slow response and sluggishness

  - by Murphy1138

  Recently updated to 12.04 x64 on my AMD HEX core 4GB system, over the last few days I feel that the overall system is sluggish/laggy , for instance hitting the dash button, the dash opens but the recent activity of files/videos etc is incredibly slow to populate, like wise in Nautilus and browsing my media, the file names are showing up but it takes an age to populate the "thumb" of the video, If I go into Gnome-shell the shell response is a little faster but again clicking on applications there is still a noticeable pause. I have the latest Nvidia Drivers loaded and I have very fast SATA drives, if I reboot into windows 7 the system is so much quicker in its response, I only use windows for games and Ubuntu is my main OS. 10.04/10.10/11.04 was Super quick and this was when the system still had a Duel Core Chip and a worse Nvidia card, 11.10 was pretty snappy, but 12.04 just feels bloated on each system I have installed it on. My hardware is more than up to the task so has anyone got any commands i can run to help diagnose the issue? Anyone else got the same problems? Thanks Murph

  My Question is what method should I use if I wanted to get the total number of characters a user inputs? without using arrays, i tried using .length() but it did not return all characters say from the first and lastname, it only returned the first name. Here's an example of my code. (Please dont laugh im really new in programming :) ) System.out.print("Enter your first and last name: "); String yourName = keyboard.next(); System.out.println("Your name has a total of " + yourName.length() + " numbers"); what happened was if i enter say "Neo Matrix" it would only return 3. I appreciate any help. thank you!

• From the Coalface - 2 - Work as hard as you can to be as lazy as you can

  - by TATWORTH

  On one project, the standard build involved building the database from scratch producing a build log that was about 100,000 lines long.  Manually paging throught this log took hours and it was very easy to miss any errors. The solution was to write a filter that read the log file and output a summary file with each output line pepended with the line number in the original file. Sucessive iterations eliminated more noise lines. Diagnostic displays required escaping. The final output was just a few hundred lines long and the errors were easy to spot. The filter program took less time to to write than one manual pass reading the log file.  The utility digested the log file in about 1 second. Now database build errors could be identified quickly instead of after hours of manual examination or lengthy system testing. A few minutes consideration of the task led to a tremendous improvement in quality.

• Scripted Motion Paths (?) (XNA)

  - by Peteyslatts

  Ok, so the title isn't the greatest because this is a lot more general. Say I want to have the player be able to hit A and have their ship model roll to the right, and shift to the right of the screen, while the camera stays centered. Would I do that through programming (ie. set waypoints for the model and keep the camera focus still) or do it through animation ( so the ship model actually rolls and moves right, and just play those frames)(I actually don't know how to do this kind of 3D animation yet, haven't looked into it. Adding it to my To Do List) This is a really vague question I know, I'll try and answer any questions. Thanks, Peter
