• Laptop resumes from suspend while lid is closed

  - by Gus

  I have a Dell Studio 15 and I am running Ubuntu 10.10. When I close my lid or select the suspend option, the machine suspends as indicated by the slowly pulsing power indicator. I'll put the machine in my bag and after a while it seems that the machine resumes, at least I think. When ever I go to get it, it's overheated and the system cannot resume. I am guessing that the processor resets in this overheat condition, but heat is still generated. This has happened about three times and I'm getting worried that I'll end up damaging the machine. How can I diagnose why the system is resuming from suspend? Can I force it to never resume from suspend if the lid is down?

• How to fix a gstreamer error

  - by BJsgoodlife

  I upgraded to 14.04 and now gstreamer is not working. What I am trying to accomplish is to hear the audio input on my computer coming from a ham radio. This is the command that I am using: gst-launch pulserc ! pulseink. This is the error message that I am receiving: ERROR: pipeline could not be constructed: no element "pulserc". I am wondering if I should purge gstreamer, or if there is another command that I should put it. Thank you again everyone for all of your help.

• What if you don't have code samples to give a prospective employer?

  - by lucks

  What do you do when you don't have any good code samples available when asked by a prospective employer? I like to consider myself a fairly capable developer but I can't share any of the software I've been writing for my company the last few years. Unfortunately, I haven't been able to find the time to put much work in my personal projects either. Basically, I don't think I can find any code samples that are a good representative of my skills that I can share. Any ideas? Thanks in advance.

• Create association between informations

  - by Andrea Girardi

  I deployed a project some days ago that allow to extract some medical articles using the results of a questionnaire completed by a user. For instance, if I reply on questionnaire I'm affected by Diabetes type 2 and I'm a smoker, my algorithm extracts all articles related to diabetes bubbling up all articles contains information about Diabetes type 2 and smoking. Basically we created a list of topic and, for every topic we define a kind of "guideline" that allows to extract and order informations for a user. I'm quite sure there are some better way to put on relationship two content but I was not able to find them on network. Could you suggest my a model, algorithm or paper to better understand this kind of problem and that helps me to find a faster, and more accurate way to extract information for an user?

• What are my tool options to prototype a 2D online multiplayer game?

  - by Asher Einhorn

  I'm looking for the best tool to allow me to quickly put together a 2D game that relies largely on networking. It's extremely likely that this game will require a server side program to constantly run. I have little experience with these things and since it's a prototype i'd like the easiest options for achieving this. I am looking to make this game for the web and mobile devices, although at present I only have access to ios hardware, (no android etc). I just want to get the bare bones of this set up so I can test it from the earliest opportunity to see if it's fun. EDIT - doesn't unity have some inbuilt networking stuff in it?

• Creating a bootable USB recovery drive to be used by someone who isn't computer savvy

  - by David

  I am looking for a way to prepare an image of an Ubuntu machine which would be bootable and installable in the easiest way possible. I'm actually preparing an Ubuntu machine for someone living far, and not computer savvy. If he ever has troubles with his installation, he could just put a USB drive in, boot the machine and everything would be resetted for him. I know there are many methods of creating/loading an image of a drive, but the ones I've found so far have complicated menus with several options to choose from, etc. Ideally, perhaps only asking a Yes/No question such as "Would you like to reinstall?" would be great. Does such a tool exist? Thank you in advance!

  - by HDInfinity

  I downloaded Ubuntu 12.04 so that I could Dual boot between Ubuntu and Vista. I am currently using a Broadcom 802.11.n Network Adapter for internet, I DON'T have access to an Ethernet connection. Is there a way for me to install the Broadcom drivers for Ubuntu while running Vista, then just install the drivers on Ubuntu from my Vista files. Or put the Drivers on a USB and install from there. There is no way for me to get an internet connection on Ubuntu without the Broadcam drivers.

• "Never to forget information" for programmers [closed]

  - by Milan

  Hi there! I'm new to programming and I would like to make a list of most important pieces of knowledge of programming and CS that would be useful no matter what specific programming language I would use in the future. For instance, if I would make this kind of list for Law studies, there would be stuff like Articles of Constitution etc. Those pieces of information I would put in Anki, and repeat it from time to time. Speaking in terms of CS and programming I mean on the most useful: mathematical theorems algorithms (examples of elegant solutions, comparison of two solutions etc.) pieces of code anything else that is vital (and very handy) to have in mind Do you think that making this kind of knowledge list makes sense?

• Own an iPad, iPhone, or Touch? Add GWB to your Home

  - by Staff of Geeks

  I know it is goofy to geek out about such things, but I am a pretty goofy geek.  Today we published support for the Apple icons for devices like the iPhone, iPad, or iPod Touch.  Now when you add Geekswithblogs.net to your home screen (via the little + in Safari) it will load the icon to the left instead of a screenshot of the site.  We have been using my iPhone and iPad to surf to GWB for awhile and we were tired of that screenshot.  Simple Google/Bing search and a little Photoshop CS5 (Amazing!!!) work and there it is.  Next step we are taking in the Apple iPad/Phone arena is getting our developer kit and seeing what possiblities there are for Geekswithblogs.net and a custom App.  Got any ideas? Here is a shot of my iPad 3G: Also, would anyone be interested in a Geekswithblogs.net custom background for the iPhone or iPad?  I can put something together real quick if there are any takers.

• What is the typical example of old school website design?

  - by Pierre 303

  I want to build a website for a retro thing that was popular in the mid 90s (beginning of the commercial internet). So I want use old designs that was very popular at that time. The first thing that comes to my mind was those "under construction" animated gifs. People often put animated gifs everywhere. But also those awful repeating backgrounds. So yes, I want my website to look exactly like in the mid nineties ;) (please suggest practical and usable features, I guess an Java Applet menu would not work today, or saying on the bottom that this website is optimized for Netscape 3) EDIT: for those that wants to see the result: Retrology

• The practical cost of swapping effects

  - by sebf

  Hello, I use XNA for my projects and on those forums I sometimes see references to the fact that swapping an effect for a mesh has a relatively high cost, which surprises me as I thought to swap an effect was simply a case of copying the replacement shader program to the GPU along with appropriate parameters. I wondered if someone could explain exactly what is costly about this process? And put, if possible, 'relatively' into context? For example say I wanted to use a short shader to help with picking, I would: Change the effect on every object, calculting a unique color to identify it and providing it to the shader. Draw all the objects to a render target in memory. Get the color from the target and use it to look up the selected object. What portion of the total time taken to complete that process would be spent swapping the shaders? My instincts would say that rendering the scene again, no matter how simple the shader, would be an order of magnitude slower than any other part of the process so why all the concern over effects?

• Can't disable giant cursors (from accessibility mode)

  - by jackweirdy

  I've just installed ubuntu 12.04 from a livecd. Out of curiosity, I enabled the accessibility options for people who are hard of sight. As you can guess this does the usual stuff of inverting colours, increasing text size and making the cursor larger. Having finished the installation I booted into the new system to find accessibility mode was still installed. From the lightdm login screen I disabled this which switched colours and text size back to default, however it's only the pointer cursor that has gone back to default. To put it another way, the "hand" icon that you get when hovering over a link, the cursor which appears when typing and pretty much every other cursor on the system are still large. I've looked on the Universal Access menu, but there's no option to disable large cursors. I've tried toggling accessibility on and off but to no avail.

• Has any language become greatly popular for something other than its intended purpose?

  - by Jon Purdy

  Take this scenario: A programmer creates a language to solve some problem. He then releases this language to help others solve problems like it. Another programmer discovers it's actually much better for some different category of problems. By virtue of this new application, the language then becomes popular for that application primarily. Are there any instances of this actually occurring? Put another way, does the intended purpose of a language have any bearing on how it's actually used, or whether it becomes popular? Is it even important that a language have an advertised purpose?

• Restricting crawler activity to certain directories with robots.txt

  - by neimad

  I would like to use robots.txt to prevent indexing of some parts of my website. I want search engines to index only the / directory and not search inside my controllers. In my robots.txt, I have this: User-Agent: * Disallow: /compagnies/ Disallow: /floors/ Disallow: /spaces/ Disallow: /buildings/ Disallow: /users/ Disallow: / I put this file in /mysite/public. I tested the file with a robots.txt validator and got no errors. However, Google always returns the result of my site. For testing, I added Disallow: /, but again, Google indexed all pages. floors, spaces, buildings, etc. are not physical directories. Is this a bug? How can I work around it?

• Save to Hard Drive instead of bootable USB

  - by WAM

  I followed the instructions on the Ubuntu website on how to put Ubuntu 12.04 on a USB and make it a bootable USB stick for windows. It worked fine and I can boot up and run Ubuntu, but every time I try to download software or change settings it tries to save it to the USB rather than the hard drive built into the computer. The USB doesn't have enough space so the download fails and in addition it doesn't retain setting changes so when I restart my computer all the settings return to default and anything I saved is gone. Is there any way to change things so that when I download software or change settings Ubuntu will save it to my hard drive instead of the USB?

• How do I fix dragging windows to the adjacent workspace?

  - by Bill O'Dwyer

  I installed CompizConfig-Settings-Manager and I put on all the settings I liked and had in 11.10, including the ability to drag my windows to the adjacent workspace. It's under the Desktop Wall section, on the Edge Flipping tab and I've checked "Edge Flip Move" and "Edge Flip DnD." In 11.10, the movement was smooth between each workspace, and the window would still be "grabbed" in the same place. In 12.04, it's leaving the window behind and the mouse appears to be "grabbing" nothing, but I'm still holding onto the window, and I can still move and place it within the workspace (or indeed the previous workspace as it won't appear in the desired place until I drag the mouse all the way to the edge of the screen). Any way to fix this? I'm running 12.04 beta 2.

• How to get scripted programs governing game entities run in parallel with a game loop?

  - by Jim

  I recently discovered Crobot which is (briefly) a game where each player codes a virtual robot in a pseudo-C language. Each robot is then put in an arena where it fights against other robots. A robots' source code has this shape : /* Beginning file robot.r */ main() { while (1) { /* Do whatever you want */ ... move(); ... fire(); } } /* End file robot.r */ You can see that : The code is totally independent from any library/include Some predefined functions are available (move, fire, etc…) The program has its own game loop, and consequently is not called every frame My question is: How to achieve a similar result using scripted languages in collaboration with a C/C++ main program ? I found a possible approach using Python, multi-threading and shared memory, although I am not sure yet that it is possible this way. TCP/IP seems a bit too complicated for this kind of application.

• How will Deja-Dup operates when backing up to an external USB drive?

  - by Little Bobby Tables

  I want to set up regular backups, and deja-dup seems like a nice tool. However, I want to put my backups on an extension USB drive that I have, not on a remote network location. Naturally, this drive is not always connected. If I configure deja-dup to backup to a directory on this drive (e.g. /media/extention/backup), what would happen? Will it prompt me to connect the drive when it is missing (the desired behavior), or just fail silently? Is there some way to tweak it to do so? I can roll my own cron-based backup script that checks if this drive is mounted, but I would really prefer to use an existing, integrated tool.

• Add ability to add tabs to the end of a line in Windows PowerShell ISE

  - by deadlydog

  Originally posted on: http://geekswithblogs.net/deadlydog/archive/2013/06/24/add-ability-to-add-tabs-to-the-end-of-a.aspxIn the preamble of an earlier post I mentioned that one of the little things that bugs me about Windows PowerShell ISE is that you can add tabs to the start of a line, but not to the end of a line.  This is likely because it would interfere with the tab-completion feature.  I still like to be able to put tabs on the end of my code lines though so that I can easily line up my comments.  Here is how we can achieve this functionality in PowerShell ISE.
