• Problem with lucid install from ISO.

  - by joon

  Hi, I am trying to install Lucid from an iso (bios doesnt let me boot from USB and dvd drive is busted). I followed the instructions on the bottom of this page: ´The CD image approach´ https://help.ubuntu.com/community/Installation/FromWindows The ubuntu ALTERNATE iso is in my c: root dir. I even tried a fix that used to work in older versions (found on a forum) but that did nothing. What happens: - boot until the boot.ini menu - select install ubuntu - select install ubuntu again, I´m assuming this is grub - do some country settings,.. - harddrive is scanned for ISO image - not found, not even with thorough search...

• Over a million COBOL porgrammers in the world?

  - by Lucas McCoy

  I think I heard on a previous StackOverflow podcast that COBOL was used as the programming language for traffic lights (or something like that), so this got me interested. I did a quick Google search and found this little article: Today, Cobol is everywhere, yet largely unheard of by millions of people who interact with it daily when using the ATM, stopping at traffic lights or buying a product online. The statistics on Cobol attest to its huge influence on the business world: There are over 220 billion lines of Cobol in existence, a figure which equates to about 80 per cent of the world’s actively used code. There over a million Cobol programmers in the world. There are 200 times as many Cobol transactions that take place each day than Google searches. I didn't really trust the source seeing as how it's on some random PHPBB forum. So how accurate are these figures? Are there really 220 billion lines of COBOL? I assume a few people/companies still use COBOL, but how many?

• OUYA and Unity set up problems

  - by Atkobeau

  I'm having trouble with the Unity / OUYA plugin. I'm using Unity 4 with the latest update on a Windows 7 machine. When I open the starter kit and try to compile the plugin I get the following error: Picked up _JAVA_OPTIONS: -Xmx512M And if I try to Build and Run I get this error: Error building Player: ArgumentException: Illegal characters in path. I'm stumped, I've gone through lots of forum posts here and on stackoverflow and I can't seem to resolve it.

• Rendering a big game universe - bitmaps or vector graphics?

  - by user1641923

  I am new to an Android development, though I have much experience with Java, C++, PHP programming and a bit experience with vector graphics too (basic 3d Studio Max, Flash, etc). I am starting to work on an Android game. It is going to be a 2D space shooter/RPG, and I am not going to use any game engines and any 3D party libs. I really want to create a very large game universe, or even pseudo-infinite (without visible borders, as if it were a 2D projection of a sphere). It should include 10-12 clusters of 7-8 planets/other space objects and random amount of single asteroids/comets, which player can interact with and also not interactive background. I am looking for a least complicated aproach to create such a universe. My current ideas are: Simply create bitmaps with space scenery background so that they can be tiled seamlessly repeated and construct my 2D universe of this tiles, then place interactive objects (planets, other spaceships) on it. Using vector graphics. I would have a solid color background, some random background objects and gradients here and there. My problems here: Lack of knowledge of how well vector graphics is integrated in Android. Performance? Memory usage? Does Android manage big bitmaps well? Do all of the bitmaps have to be in memory during all game process? I am interested in technical details regarding each of the ideas and a suggestion, which I should go with.

• Cisco Linksys AE2500 wireless adapter not working

  - by makuto

  I have a Cisco AE2500 I've used with my laptop to get internet. I had to install the drivers by following this forum: http://ubuntuforums.org/showthread.php?t=1805830 But now the blue light on the adapter doesn't turn on at all, but ndiswrapper reports it is connected. I have no connection to the internet on my laptop, and the adapter doesn't show it's blue light on any of the USB ports of my computer or on the 4 port hub I have. Is there some way I can reset something so that the blue light will show again? I'm using Ubuntu 11.10 on a Dell Latitude D505 laptop. EDIT: I deleted and reinstalled the same exact driver and everything worked again.

• How do I create a camera?

  - by Morphex

  I am trying to create a generic camera class for a game engine, which works for different types of cameras (Orbital, GDoF, FPS), but I have no idea how to go about it. I have read about quaternions and matrices, but I do not understand how to implement it. Particularly, it seems you need "Up", "Forward" and "Right" vectors, a Quaternion for rotations, and View and Projection matrices. For example, an FPS camera only rotates around the World Y and the Right Axis of the camera; the 6DoF rotates always around its own axis, and the orbital is just translating for a set distance and making it look always at a fixed target point. The concepts are there; implementing this is not trivial for me. SharpDX seems to have has already Matrices and Quaternions implemented, but I don't know how to use them to create a camera. Can anyone point me on what am I missing, what I got wrong? I would really enjoy if you could give a tutorial, some piece of code, or just plain explanation of the concepts.

• How do I change the volume control icon?

  - by Richard Oren Pincook

  I recently switched to gnome 3 (love it!), but the default icon theme was a little dreary and gray, so I switched that back to ubuntu-mono-dark. But now whenever I change my volume, I get this ugly pixelated icon show up. The forum says I don't have enough reputation to post an screenshot, but it's pixelated and ugly with these fuzzy straight blue lines that turn on as the volume goes up. I found identical images in the Humanity and Humanity-Dark icon themes (one example: /usr/share/icons/Humanity/status/24/audio-volume-high.png). I tinkered with the images by changing their names, temporarily deleting them, etc. But it had no effect on the ugly icon. What file is responsible for violating the beauty of my desktop?! Once I find it, I can replace it.

• How to avoid mediocre CV.

  - by QriousCat

  Though in every project we (testers) face different set challenges, when it comes to CV, more or less we have same responsibilities. For example responsibilities like understanding requirements, preparing and executing test cases, creating defects, liaising with dev, BA teams will be repeated for every project we involve. If we keep writing same responsibilities for every role, CV becomes mediocre and a yarn. In fact most of the testing resumes I have come across are like that. How do I avoid repetition of responsibilities in my resume and make it more interesting? If this is not the correct forum for this question let me know. Thanks in advance for your suggestions.

• Precision loss when transforming from cartesian to isometric

  - by Justin Skiles

  My goal is to display a tile map in isometric projection. This tile map has 25 tiles across and 25 tiles down. Each tile is 32x32. See below for how I'm accomplishing this. World Space World Space to Screen Space Rotation (45 degrees) Using a 2D rotation matrix, I use the following: double rotation = Math.PI / 4; double rotatedX = ((tileWorldX * Math.Cos(rotation)) - ((tileWorldY * Math.Sin(rotation))); double rotatedY = ((tileWorldX * Math.Sin(rotation)) + (tileWorldY * Math.Cos(rotation))); World Space to Screen Space Scale (Y-axis reduced by 50%) Here I simply scale down the Y value by a factor of 0.5. Problem And it works, kind of. There are some tiny 1px-2px gaps between some of the tiles when rendering. I think there's some precision loss somewhere, or I'm not understanding how to get these tiles to fit together perfectly. I'm not truncating or converting my values to non-decimal types until I absolutely have to (when I pass to the render method, which only takes integers). I'm not sure how to guarantee pixel perfect rendering precision when I'm rotating and scaling on a level of higher precision. Any advice? Do I need to supply for information?

• Will many links to the same page without nofollow penalize the host site in the search engine rankings?

  - by Evgeny

  May be a silly question, but I'll give it a shot :). On my forum app I would like to allow users with sufficiently high reputation display links to their home pages under every post - without the nofollow attribute (while lower rep users will have the nofollow) I am happy to help the site contributors improve rankings of their own, but not sure if this can actually deteriorate the rank of the host (the site that hosts those links) - as potentially the same link to the user's home page may be peppered in the pages of the host. What do you think? Thanks.

• Help Desk Software with user groups and temporary ban function?

  - by Zillo

  Does anyone know any Help Desk Software which allow you to create user groups / to mark/categorize specific users in some way / and to to ban specific users/e-mails (not user groups) for a specific period of time? Kayako? OTRS? simpledesk?... Kayako looks to be very functional but not sure if it has this option. zendesk is also very functional but a SaaS service not a downloadable software. Since the functions that I am saying are very common in forum software, maybe simpledesk could do it since it is based in SMF. Any ideas?

• Are there any good guides for making mods for Minecraft?

  - by Pureferret

  I've been coding in Java for 5 months at work now, and having past experience with programming in other languages, modifying existing code at Uni etc. I feel like I want to get started on (read: continue learning to program by) modding with minecraft. I know what I need, but not exactly how to do so. I once saw some good guides on the minecraft forum, but they all explained how to write in java, hows different classes in the code work etc. I'm more interested in how you decompile the code, write your own separate from the main 'trunk' of minecraft and then package it to install with a tool like 'Magic Loader'. My issue with these guides is that they always relied on being in windows, but I'm primarily a linux user, and the guides on the forums only seemed to assume you were on a Windows box. So is there a good 'walkthrough' for modding for Minecraft? Especially one where it assumes or at least allows for the fact you are in linux?

  Hi I don't know if it is appropriate to ask this question here. The moderator can delete this question after getting answered if he finds this question as inappropriate in this forum I'm performing a project course work in my computer science department. For example I don't know how to develop logic for some requirements in my project and I find the code in some tutorial. If i implement the feature along the same lines mentioned in that tutorial. Does it constitute academic plagiarism ?? Thank you in anticipation.
