• Data structure for file search

  - by poly

  I've asked this question before and I got a few answers/idea, but I'm not sure how to implement them. I'm building a telecom messaging solution. Currently, I'm using a database to save my transaction/messages for the network stack I've built, and as you know it's slower than using a data structure (hash, linkedlist, etc...). My problem is that the data can be really huge, and it won't fit in the memory. I was thinking of saving the records in a file and the a key and line number in a hash, then if I want to access some record then I can get the line number from the hash, and get it from the file. I don't know how efficient is this; I think the database is doing a way better job than this on my behalf. Please share whatever you have in mind.

• Adding icon to the system tray (notification area)

  - by Moma Antero

  Hello, I have a small audio recording application programmed with GTK/GDK. (see picture). And I would like to add a tray-icon for it so users can control the application window and recording from it. Adding a tray icon: I have planned to use the GtkStatusIcon class for this task. Ref: http://library.gnome.org/devel/gtk/2.11/GtkStatusIcon.html Is GtkStatusIcon the recommended solution that also works in Ubuntu's Unity and in the GNOME 3.0 desktop? I already googled a bit and found a good example on GtkStatusIcon. Could I also use Libindicator for this task? Ref: https://launchpad.net/libindicator

• What to use for an event listing site? [on hold]

  - by Vykintas

  I have a site which lets users buy & sell tickets, but it's built on wordpress & buddypress. So it's very heavy and messy. I would like to re-do the whole site on something lighter, cleaner and solid. The main functionality for user would have to be as follows: Register or login via Facebook. Create events and sell tickets to them. See ticket sales statistics Upload photos and associate those with events. Buy event tickets, print pdf ticket. Comment, favourite and like events. What would be your suggestions? PHP framework? CMS? CMF? I must say that I'm a front-end dev so building a system from scratch on my own would take a while. I'd be interested more in a "skeleton" app solution or something similar.

• 3D Mesh Collision Help

  - by BlackAfricano

  I am new to XNA (I have only been working in it for a countable number of weeks) as well as to these forums (I have only made 1-2 other posts), so this may seem like a strange request, but I am wondering if anybody knows about more advanced collision in XNA. So far I have only been able to figure out BoundingSphere's which seem to be the simplest of the methods, and I was thinking of looking more into BoundingBoxes because the game I have is a 2-3D platformer. The problem I realized was that if I wanted to get any more advanced than stages in the shape of a box, I would face some immediate dilemmas. I was hoping somebody here was knowledgeable on the subject and could inform me where I could get started learning how to do something like this: https://www.youtube.com/watch?v=ekMD_Gtt8d4 Although the game in this video isn't very pretty, the mesh collision looks like what I'm looking for. I am hoping for the most complete solution, if possible.

• Synchronizing Mysql Table Schema [on hold]

  - by user1122069

  I have some difficulty keeping track of my SQL changes in a text file in SVN. One solution that I am aware of is to put the SQL queries in files (1.sql, 2.sql...) and to manually load each file at the proper time. Besides missing commas, the process is too cumbersome when builds become more frequent. I have actually taken to asking a co-worker to send me his SQL changes on Skype and we just apply the changes immediately on our local, development, and production servers (using three PhpMyAdmin tabs). I have seen several GUI tools mentioned in similar questions on SO, but these are actually more work and less automated than the aforementioned methods. Is there any standardized process by which this is done in an automated way? I can only guess that large companies build their own mechanisms of keeping track of database schema changes (yet I can't find a word about it - maybe they use files?). This question was closed as off-topic on Stack Overflow, so I am re-posting it here.

• optirun fails in Ubuntu 12.10

  I am trying to use Nvidia Optimus on my laptop by using Bumblebee, I have an Intel Core i5 with an Nvidia Geforce GT 630M. I have followed the instructions on the wiki page at https://wiki.ubuntu.com/Bumblebee, but when trying to run optirun with Firefox (or any other program, like glxspheres), I get the following error: [ 1921.452820] [ERROR]Cannot access secondary GPU - error: Could not load GPU driver [ 1921.452905] [ERROR]Aborting because fallback start is disabled. I have tried googling the issue but I couldn't find any solution that didn't cause more problems. Thank you for your time. Here is my bumblebee.conf: http://paste.ubuntu.com/1333324/

• CLI Shared Hosting Management (scripts to manage web users and hosts) [on hold]

  - by aularon

  I am currently administrating two servers: first one has no control panel, I am creating directory structure, setting permission, configuring different aspects (users/php-fpm pools, nginx hosts..) for each of sites. With more clients, I sat up ISPConfig on my second server, everything is easily handled by ISPConfig Web Interface. However, I am searching for a CLI based solution, i.e. a set of scripts to create and manage hosts. Basically, a method to control ISPConfig from the command line (so I can use it over SSH) would be a good start. Does anybody know of such effort? I searched but all I got was web based solutions. Thanks.

  Office bientôt sur iPad ? Microsoft travaillerait sur le port de sa suite bureautique sur iOS Microsoft travaillerait activement sur l'adaptation de sa suite bureautique Office pour l'iPad. Selon le quotidien The Daily et des sources anonymes, l'éditeur pourrait dévoiler une application Office pour iPad avant le lancement de la prochaine version de la suite bureautique pour Mac, en début de l'année prochaine.

• How do you assign commands to keys to in Terminal?

  - by NES

  Is there a solution to assign special key combinations to words in terminal use. For example the less command is very usefull and i use i a lot to pipe the output of another process through it. The idea would be to set up special key combinations that are only active in terminal use assigned to write different commands? So pressing CTRL + l in terminal window could write | less or CTRL + G could stand for | grep Note: i just mean adding the letters to commandline not execute the finally. A similar way what's tabcompletion but more specific.

• Update to 13.10 without GUI access

  - by Tom

  After upgrading 13.04 with the latest patches, I'm getting some really weird problems -- namely, logging in at the GUI just dumps me back at the GUI login screen. I can, however, get command line access from Ctrl-Alt-F1, and remotely via SSH. Given that I was doing these updates to step to 13.10, I figure I might as well continue the process, and then deal with the fallout once I get there. However, how can this be achieved with only the command line, and no X available? The only method I've found thus far is to run 'update-manager', which does not appear to have a CLI mode (and will not start without access to X). What's the solution? Thanks!

• Are there any resources for motion-planning puzzle design?

  - by Salano Software

  Some background: I'm poking at a set of puzzles along the lines of Rush Hour/Sokoban/etc; for want of a better description, call them 'motion planning' puzzles - the player has to figure out the correct sequence of moves to achieve a particular configuration. (It's the sort of puzzle that's generically PSPACE-complete if that actually helps anyone's mental image). While I have a few straightforward 'building blocks' that I can use for puzzle crafting and I have a few basic examples put together, I'm trying to figure out how to avoid too much sameness over a large swath of these kinds of puzzles, and I'm also trying to figure out how to make puzzles that have more of a feel of logical solution than trial-and-error. Does anyone know of good resources out there for designing instances of this sort of puzzle once the core puzzle rules are in place? Most of what I've found on puzzle design only covers creating the puzzle rules, not building interesting puzzles out of a set of rules.

• HTG Explains: What are Shadow Copies and How Can I Use Them to Copy or Backup Locked Files?

  - by Jason Faulkner

  When trying to create simple file copy backups in Windows, a common problem is locked files which can trip up the operation. Whether the file is currently opened by the user or locked by the OS itself, certain files have to be completely unused in order to be copied. Thankfully, there is a simple solution: Shadow Copies. Using our simple tool, you can easily access shadow copies which allows access to point-in-time copies of the currently locked files as created by Windows Restore.

• How do I install the NVIDIA driver for a GeForce 6200?

  - by 2d4skt

  I have been recently trying to find a solution for this on the web but did not find something useful or accurate for Ubuntu 11.10. I also consulted the NVIDIA help, but things there did not work for me. I installed the additional drivers from system settings but they are not fully compatible with my GeForce 6200. First I tried finding how to stop the X server. I succeeded, but another problem was the nouveau kernel. This is really frustrating. Can anybody tell me an accurate and authentic way to install NVIDIA drivers?

• cannot unlock login screen 14.04

  - by LittleNooby

  When my computer boots, entering the correct password won't start my session. I found out the problem is /home/user/.Xauthority ownership. root owns this folder and giving the ownership to the user will solve the problem... for a while. I don't know how or when, but the ownership will go back to root pretty often; It can happen just after one boot or ten. Is there a definitive solution to this problem?

• Limiting the speed of a dragged sprite in Cocos2dx

  - by Frozsht

  I am trying to drag a row of sprites using ccTouchesMoved. By that I mean that there is a row of sprites (they are colored squares) lined up next to each other and if I grab one with a touch the rest follow it. However, if the sprite that is selected by touch moves too fast it creates a slight gap between it and the following sprites. How do I go about limiting the speed that I can drag the sprite with ccTouchesMoved? This is the only solution I could think of to my problem. If anyone has another suggestion to prevent this sprite gap from happening I would appreciate it.
