• Two problems, both with either lock or suspend.

  - by user199208

  I recently did two things that may be the cause of either of them. 1) I started using a second screen 2) I installed xscreensaver instead of the stock, power saving option. My first question is about suspend: every time I wake from suspend, networking is disabled. While I've seen multiple posts about that on here, it didn't start happening until recently. Second, lock seems to be disabled now. Are both of these problems a bug, or was this caused by the second screen or maybe xscreensaver?

• What are the different ways of making a Joomla! website mobile friendly?

  - by Treebranch

  I am involved in the development of a number of Joomla! websites and we would like to make these websites mobile friendly. I have done a bit of searching online and I can't seem to find any standard way of doing this. I have have come across a few Joomla! extensions that claim to make themselves mobile friendly for this device or that device. However, I am weary to just start trying these out. Do any of you know of standard ways to make a Joomla! site mobile friendly?

• How do I recover when Compiz crashes?

  - by winchendonsprings

  Often compiz will crash and leave the keyboard useless. Normally I drop to the console and restart GDM. Is there a solution where I can start Compiz back up without losing everything in the current session? compiz --replace & That's how I usually restart Compiz when it crashes and I can still use the keyboard. (If you have a tip on how to prevent Compiz from crashing I've posted here Fresh install of 11.04x64 - display(compiz) constantly failing ??? - Am I right that Compiz is failing or is it X?

• Development methodology for single web developer?

  - by CaseTA

  I'm a web developer who mostly works with the LAMP stack when it comes to my own projects. Most of the time I just start coding on a project and fixing bugs and adding features as I go along. Often I'll try to use an existing solution such as Wordpress or Drupal. Now that I'm thinking of creating my own web application with businesses as the target group, I feel there's a need for proper analysis and design. Something lightweight for a one person project and still solid enough to handle requirements, user interfaces, security, etc. If you could recommend methodologies and literature I would be grateful.

• Returning multiple results from one row [migrated]

  - by krock

  I have a set of MySQL data similar to the following: | id | type | start | end | ============================================= | 1 | event | 2011-11-01 | 2012-01-02 | | 2 | showing | 2012-11-04 | 2012-11-04 | | 3 | conference | 2012-12-01 | 2012-12-04 | | 4 | event | 2012-01-01 | 2012-01-01 | I want to retrieve events within a certain date range, but I also want to return individual results for each row that has a time span of more than one day. What's the best way to achieve this? Using PHP is a possibility, but I wanted to avoid doing this because I will need to to take pagination into account, etc. Any ideas would be greatly appreciated.

• How do open-source projects grow?

  - by dan_waterworth

  I know of lots of software that is open-source. For at least some of it, someone, somewhere must have written the first version alone. How does good open-source software become well known? I'm most interested in the first steps. How does software written by one person gain its first new contributors? I'm looking for practical advise. I've started a project here, called aodbm. What steps can I take to give it the best possible start?

• How to stop running pidgin at logins and disable window hiding feature?

  - by Behzadsh

  Every time I login into my desktop, pidgin start behind, and sometimes it's bothering me - e.g. when I'm not connected to Internet or when I don't want to be on-line - I check startup application list and there's no pidgin listed. another thing that is very bothering is hiding window feature or what ever it called. assume that you're using MusicTracker plug-in, your status is Busy and you're chatting with someone. when music change, status will change, and then buddy-list will disappear and chat window will minimize. Buddy-list is not important but minimizing chat window when you're chatting is bothering, Is there any way to make pidgin stop that?

• Error after installing Ubuntu 12.04 using Wubi

  - by KJ50

  After using Windows Ubuntu Installer from within Windows, I am prompted to restart, so I follow the directions. When I try to start Ubuntu after restarting, the desktop background appears, but then a loading bar with this title appears. Verifying the installation configuration... While this is loading, an error window pops up that says No root file system is defined Please correct this from the partitioning menu There is only an 'Ok' button available to click, and if I click that the same error window appears. I do not know how to get to the "partitioning menu" from this state, so the only option I have is to shut down my computer. What can I do so that Ubuntu finds a "root file system"? Can I diagnose this problem via Windows? Does anyone have any insight? FYI - I am using a new ultrabook with 6GB RAM, Intel i7 3rd gen processor, and no CD/DVD drive.

• Beginner's steps to game programming [on hold]

  - by CodeTrasher

  I have graduated from university less than 6 months ago and became a B.Eng in Software Engineering. I have moderate understanding of programming experience from languages like C++, Java and C#. But mostly on simple desktop and mobile applications. I've tried some simple Pong-like games but never finished even the smallest game. I have a couple of nice ideas growing (IMO, at least...) in my mind but don't really know where to begin. 2D is way to go, of course, at the beginning. I just want to hear from more experienced game devs how they started out. Should I make a rough outline of the core idea and mechanics and start working on a prototype of core gameplay? Or should I just practice more by making Pong, Asteroids and that sort of games and get an understanding of those before moving on? Thanks to all!

  - by Joshc

  I have a website which I am using google analytics to track visitors and track our banner campaigns.

• New Development Snapshot

  I finished all the .NET 4.0 security model changes. If you build from source, you can now (optionally) build on .NET 4.0 and get native .NET 4.0 assemblies that use the new .NET 4.0 security model (and also experimental class gc support). The .NET 2.0 binaries also work on .NET 4.0. This is probably the final development snapshot before the first 0.44 release candidate and it has been tested more than a typical development snapshot. Please start testing ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.

  - by EricFromSouthPark

  I want to start looking for jobs in great companies and I have four years of enterprise corporations development, three years with C#.NET and alomst one year with Ruby On Rails, JS, etc... But when I look up interview questions from Google, Amazon, Fog Creek, DropBox, etc... they are really targeted at students that are coming fresh out of college and still remember what was Dynamic Programming and Dijkstra algorithms ... but I don't! :( It has been a while for me ... If a I need a sort algorithm I would either Google it or there already is a library and method that does it for me. So what should I do? Do they realize that this guy is not coming from college and will ask more general questions about software architecture or nop! I should go back find my old Data structures book from the storage and read them? In that case wht books and language do you recommend to hone my skills?

• Issue with permanent redirect implementation

  - by Argoron

  I have a tricky problem related to 301 redirections I badly need help with. I tried to implement these via .htaccess, but ran into trouble. The start of my .htaccess looks like this: SetEnv PHP_VER 5 Options +FollowSymlinks RewriteEngine on # Redirect non-www to www RewriteCond %{HTTP_HOST} !^(www\.|$) [NC] RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L] #--- GENERAL --- RewriteRule ^index\.html$ index.php [L] ... When I try to put a permanent redirect to index.php by adding R=301 in the square brackets, I get a 404, and I have no idea where the error comes from.

• Is there any simple way to access installed programs?

  - by Anentropic

  Just installed Ubuntu for the first time... Is there any simple way to browse installed programs? On Mac there is the Applications top-level folder... here I see Desktop, Documents, Downloads etc but no Apps? That'd be a good idea, no? (is there some way to create this myself?) On Windows there is the Start menu... Here it seems like I have to click the 'Dash Home' and then I can see 'Recent Apps' ... I can search for them (I'd rather not) ...or I can click the ruler/pencil icon at the bottom and see 'Recent Apps' and click to expand 'Installed Apps' ...ok that's all of them - is it possible to get a straight list view instead of the hard-to-scan wrapped rows? Also, is there any way to get rid of the pointless random selection of 'Apps available for download' at the bottom?

• ASP.NET Performance Framework

  At the start of the year, I finished a 5 part series on ASP.NET performance - focusing on largely generic ways to improve website performance rather than specific ASP.NET performance tricks. The series focused on a number of topics, including merging and shrinking files, using modules to remove unecessary headers and setting caching headers, enabling cache busting and automatically generating cache busted referneces in css, as well as an introduction to nginx. Yesterday I managed to put a number...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• How do I get started with fog type effects in a first person game?

  - by Dream Lane

  Hey guys, I'm currently using JME3 to learn 3d game development in java, and I have run into a situation. I would like to add fog effects to my games, but I don't even know where to start to implement this. I know how to set the camera's far frustum to limit the render distance, but that just simply makes a sharp cutoff. I'd like the fog it up a bit to make it feel more natural. I'm looking for an answer that points me into the correct direction. I'm not looking for specific code snippets or even JME3's engine specifics. I just want to get an idea of how this stuff works in general. Thanks!

• Starting with JMF

  - by Fasih Khatib

  I have recently downloaded JMF and don;t know where to start. Most online resources begin directly with programming and give no background of the JMF classes what so ever. So, I was planning on using a book or something that would give me ground-up knowledge of JMF. However, the books available on Amazon are of 1980's and 1990's. Can you please suggest any good books or references? Books preferred. Note: There was this one 2011 book available that was a print-on-demand collection of wikipedia articles on JMF but I decided not to opt for it because wikipedia articles should not be sold for money

• Is there a way to force lubuntu screen resolution?

  - by za1

  I have a Dell Inspiron 4000, 900 Mhz Pentium III, 192 MB RAM,10.1 GB disk running Lubuntu 12.04. When I start the computer, and I check the display resolution, Monitor Settings claims that the max resolution is 1024x768. I then connected another monitor I had lying around, rebooted, and now the laptop monitor looks normal,and monitor settings claims that 1280x1024 is the max resolution (it is) and the other monitor doesn't turn on. (black screen) The external monitor is not broken. Is there a way to, without the external monitor, force the laptop monitor resolution to 1280x1024? (The following is another question) - How can you run commands automatically at startup? Specifically "xinput 18 118 0" (without quotes) The first question is important, I can live with typing the second one at every boot. Thanks
