• How to setup an intranet in ubuntu using wifi?

  - by ved2254

  I want to set up a VPN on my laptop but I don't know what and how to set it. My requirements are : Intranet with a customizable list of shared folders. Intranet outsourced via computer wifi. Possibly assigning individual private IP addresses to all connected. Facility to share internet (if hassel free). Can I do this using Gnome Network Manager or do I need another program? I'll be happy even if I get one folder to share for the time being and no internet if I could only outsource one file/folder.

• Term for Production Rollback

  - by trainer

  The firm I work at keeps a copy of the compiled source code on production. So basically on our Production server, we have two folders: ProductionServer\SourceCode\ ProductionServer\SourceCodeRollback\ The Rollback folder always contains one version older code. This is done so that on deployment nights, if something is wrong with the new code, the deployer(who is not familiar with source control software) has the older version to revert back to. My question is: Is there an official computer science term/nomenclature for the Rollback folder? Or is "Rollback" itself the official term?

• how to get started with a game engine [closed]

  - by user19343

  I'm a 3rd year Computer Science student and I would like to get started with building a game engine or at least tinkering with making one. I am curious if there are any good resources to use to get started. I get the idea behind different pieces in the engine, but I'm not really sure about how they fit together. Is there anything out there to help teach me the skeleton of a game engine? So far I've been playing with the idea of a game engine that uses modules built in a circular linked list so that each can do it's computing and then pass move to the next piece of the engine to work.

• 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.

• What steps should be taken to make sure your software is usable by disabled people?

  - by Cromulent

  I want to make sure a piece of software I am writing is usable by people with various disabilities such as blindness and an inability to use a mouse and / or keyboard. Unfortunately I have no experience with things such as screen readers or other methods that disabled people use to make using a computer easier / possible. I've never really had much experience with disabilities at all and unfortunately I don't know any disabled people who I can ask. I was wondering what other people do to make sure that their software is available to a wide range of people with varying abilities? This seems to be a subject matter that is often ignored by developers and I think it is a real shame.

• Mouse cursor lag after lock screen, 64 bit 12.04

  - by Bill Jones

  Recently I have noticed that when I return to my computer after it has been "locked" for a while, the mouse pointer has significant lag. The cursor position appears to only update a few times a second. Moving the mouse results in the pointer "following" the movement in a jerky kind of way, and then continuing for some fraction of a second after I have stopped using the mouse. Replacing the mouse has no effect. (I have two differently branded and constructed usb optical mice). Plugging either mouse into a different usb port has no effect. Once the problem was resolved by "suspending" the system, and then re-starting it with the power switch, but this does not work every time. So far, the only fool-proof fix is to shut the system down and re-start it (re-boot). I have tried this suggested fix. It had no effect.

• Programming jobs for a science based degree [on hold]

  - by clairharrison

  I am currently in my last year of a Masters in Physics at Uni and I am looking to go into a job that is mainly programming based. As part of my course we have learnt C++, Matlab and as a hobby I taught myself HTML, CSS, JAVA and a bit of JavaScript. After getting to this stage in my degree I've realised that its actually the programming side of Physics that I enjoy most. I've been working on a few Android apps & websites in my spare time but only things that utilize what I know in JAVA, HTML etc. Using Physics in programming is good fun but I don't want to limit myself just to Physics based jobs. I just want to know a few things: What kind of jobs can I apply for that would require the kind of skills I already posses/can work towards possessing in a year Can I compete with graduates who have had a lot more programming in their course for example Computer Science? Are there any specific extra things I need on my CV before I start applying for these jobs?

• How can I manage keyboard shortcuts in 11.10 Oneric?

  - by Mike

  In 10.04, I've had a keyboard shortcut defined via it's keyboard settings applet. Recently I have upgraded to 11.10 (I use gnome-classic). This shortcut still works, but I can't find it in System Setting's Keyboard applet. This means I don't know how to disable it. Not that it bothers me too much (now, at least), but not being able to control my own computer doesn't seem very pleasant. Where does Ubuntu store my keyboard shortcuts? BTW, I do not use compiz, and I can't find my shortcut in gconf either.

• Function keys and Hot are switched

  - by Brian

  I recently got a new laptop and installed 12.10 on it. I noticed right away that the "hot keys" on the F keys didn't always do what was pictured and also I noticed that the "hot keys" and the function keys were reversed. e.g. to close a window I have to hit alt-fn-F2 instead of just alt-F2. This is pretty annoying because I've been using the same keyboard shortcuts for years and I don't really want to have to re-learn them. I would also like to switch what the hot keys do, for example the F3 key is pictured as increase screen brightness but it really puts the computer to sleep. I would like to change this back to increase the brightness I looked in keyboard shortcuts settings but these options are not in there. I also downloaded gconf-editor but was unable to find where to change the shortcuts on it. (they weren't at apps \ metacity \ keybinding_commands like others described) any help would be greatly appreciated

• What's the best way to add some particle or laser effects to an already animated character?

  - by Scott

  I just purchased some rigged and animated robot characters from 3drt for a game I'm making in unity. I would like to be able to add some weapon effects to the characters. For example, I would like for the robots to be able to shot lasers out of the hands at enemies. I have know idea where to even start with this task as I'm more of a programmer than a graphics guy. Can some experienced developers / designers please point me in a good direction? Thanks. Note: As of right now I have maya and blender installed on my computer.

• Failed Update & Mouse Issues

  - by James

  I`m using my gfs computer - but I do have Ubuntu 11.10 up and running well to some degree. Still need to work out some bugs but not quite sure how to do that. My mouse is only somewhat responsive - cursor moves, and able to click on things but still unable to do a double click function. Left mouse button still not working at all. Tried running updates but it keeps coming up synaptic error. Not sure what that means. I have read that some people have done reinstalls of Ubuntu and it corrected the problems - not sure if that could work. Comments would be appreciated. Installed Ubuntu 11.10 but thinking of trying to wipe the system to do a fresh install can someone tell me how I get back to the Ubuntu installation menu. Wondering if gnome may need to be reset but not sure.

• Android Application for Final Year Project [closed]

  - by user1070241

  I hope this is the right place to post this question. Basically, I'm about to choose a Final Year Project for my third and final year in BSc Computer Science. I have worked with different apps and therefore I do have some experience with the Android SDK Platform in general. However, my question is this, how do you think an Android based project would go down with potential employers? I personally don't think the complexity of this project is lower than other projects proposed by my university. Please let me know what you think, and do share any experiences that you have had with this, if any. Thank you very much.

• Topics for covering in-depth programming knowledge

  - by black_belt

  I pursued my bachelors' degree in business administration, but my interest in Information Technology led me to acquire some knowledge of PHP programming and MySQL database. I find programming so interesting that I haven't applied for any job since my graduation. Currently I am staying home and just trying to acquire in-depth knowledge of PHP programming. So far I have developed couple of websites and web applications including Inventory+ Point of Sale Software and an Accounting system for small organizations. I aim to have knowledge that a Computer Science graduate should have, and for that I want to read books but I have no idea where to start from. Could you please suggest me some books and topics that I should study on? Thanks a lot :)

• best programming language for a web based game?

  - by Adam Geisweit

  what programming language would be best for making a web based game to be played in a browser, and where would i be able to find tutorials on how to use the language? i have looked up silverlight in xna (because that was what i was most fluent with), but it made my projects unusable for a month until i got all of silverlight off my computer. i have looked at java and javascript, but i have found no suitable places where i can learn to create games on either of these, just the basics of the language. does anyone have any advice on this?

• How can I fix my problems with fonts in Firefox?

  - by snostorm

  Ever since I reinstalled Ubuntu a few hours ago, I've experienced major visual artifacts with smaller font sizes in Firefox. The fonts end up looking like this: Or even like this: This only occurs in Firefox; other applications are unaffected. It also occurred on the LiveUSB I used for installation, making me suspect a hardware or driver issue. The output of lshw on my computer is here: http://pastebin.com/LnSt6veT. Any idea what might be causing this, or how I can fix it? ... and "Use Google Chrome" is not a valid answer. ;)

• PC noisy due to high load - why?

  - by Jinx

  I just installed an ubuntu on my pc(Dell Inspiration I560SR-358, with CPU E5700 3GHz, 4G memory, and NVIDIA GeForce G310). The pc becomes noisy before that it's quiet with a windows 7 on it. How come? How to set it to be quiet again in unbuntu 10.04. One of the two cpu usage is always 100%. I think that is the reason. //re-edit Everything gets ok after I restart the computer.But the fan is still running which makes it noisy, if i switch to windows 7, it becomes quiet again.

• If a variable has getter and setter, should it be public?

  - by Oni

  I am an about to graduate Computer Science student so probably this is a stupid question. If I have a class with a variable that is private and the class have getter and setter for that variable. Why don't make that variable public? The only case I think you have to use getters and setters is if you need to do some operation besides the set or the get. Example: void my_class::set_variable(int x){ /* Some operation like updating a log */ this->variable = x; } Thanks in advance!

• Ubuntu 12.04 USB wireless not recognized

I also have no way of using a wired connection at the moment. Thanks for any help!

• Best options for freelance or part-time programming? [closed]

  - by Andrew

  I apologize in advance if this is an inappropriate question for this SE. A few years back I was all set to study computer science and get a job programming, but went a totally different route and went into healthcare. I currently work as a paramedic on a rotating 24/48 schedule, so I have two days off for every day I work, and a decent bit of downtime on the days that I do work. I've been looking at ways to earn some extra money with all that spare time, and was wondering if it'd be worth the effort to try and find a part-time/freelance gig. I know HTML/CSS, PHP, and I'm pretty familiar with Python and Ruby (and Rails). Anyways, was hoping that someone could point me in the right direction as what "skill set" would give me the best chance to be able to land a part-time/freelance gig. I realize this is a rather open-ended question but any direction is appreciated.

• Chromium and Google Chrome downloading

  - by user286166

  Well, I have sincerely enjoyed having Google Chrome on my linux machine, and have never had any problems until recently. I found that Google Chrome will simply not allow redirected downloads to start. I can download from direct links, but not pages that redirect and "Start in 3 seconds..." I immediately assumed it was the webpage itself, so I refreshed many times. I then restarted the browser, and after another failed attempt, my computer. After that point, I suspected my internet provider was to blame. I tried the redirection link in an alternative browser (Midori), and it worked perfectly fine. I decided it must be the version of Chrome that Google put out, so I quickly installed Chromium, and to my dismay, ran across the same problem. I can live with copying and pasting the url into Midori for redirected links, but I'd like the convenience of staying in my main browser. Thank you for any advice in advance. c:
