We are building a multithreaded game engine and we've encountered some problems as described below.
The engine have 3 threads in total: script, render, and audio. Each frame, we update these 3 threads simultaneously. As these threads updating themselves, they produce some tasks and put them into a public storage area. As all the threads finish…
When I start the compiz fusion icon Application from the shell I get the following output but no icon and no GUI:

Libxml2 is the faster, stable and most popular "open DOM engine"... And the "XML C parser and toolkit of Gnome".
The initial release of Libxml2 was September 1999, 13 years ago. XPath v1.0 was also released at 1999.
XPath v2.0 became a recommendation on January 2007, 6 years ago.
We can suppose that the Libxml2 community have time and…
I've been looking into in state online degree programs 'to fit my busy lifestyle' (i.e. three children, wife and hour and a half commute).
One interesting one I've found is that Master of Engineering in Professional Practice. It looks more useful and practical than a MBA in project management. I'll contact the admission dept there…
In Windows I used command-line clipboard copy-and-paste utilities...
pclip.exe and gclip.exe
These were UnixUtils ports for Windows (but they only handled plain text).
There were a couple of other native Windows utils which could write/extracy any format.
I've looked for something similar in Synaptic Package Manager, but I…
Today I checked in a change on some code which turned out to be not working at all due to something rather stupid yet very crucial.
I feel really bad about it and I hope I finally learn something from it. The stupid thing is, I've done these things before and I always tell myself, next time I won't be so stupid... Then it happens…
What is the standard way of describing how software products are released and the proportionate order of magnitude to which the changes relative to the software product are conveyed?
Is
Release
Update
Patch
Bug Fix
redundant?
or Is
Update
Patch
too terse?
As an end user I'd think that all bug fixes are patches…
I am seeing several questions similar to mine, but none of the answers are sufficient. I am pretty green with Ubuntu, so here goes:
I was just automatically upgraded to xfce 4.8 for Ubuntu studio. The volume control no longer works in my panel. When I launch 'mixer' I don't see any settings, either.
When I try to run "linux…
My application Variety Wallpaper Changer runs from /opt/extras and uses an indicator icon. I would like to make this indicator icon theme-specific. As far as I understand the standard way is to install named icons into /usr/share/icons with xdg-icon-resource at installation time (Am I right about this?). I have two questions…
It seems the bluetooth subsystem shows some bugs after the upgrade to 13.10. It was working quite happily at 13.04.
The bluetooth mouse I have, simply won't connect after the computer goes into any sort of sleep and has to be re-added each and every time. Sometimes the the entire bluetooth stack has vanished alltogether.

After installing Ubuntu 11.10 on a new computer everything worked fine for a few weeks and now suddenly when starting up Ubuntu I get a blank purple screen with no "ubuntu" splash and the 5 dots but the system does start up.
What has happened to loose the ubuntu splash screen?
Also, I've checked in the grub startup and…
The GNOME community released GNOME 3.4 today. This release contains several new accessibility features, along with a new set of custom high-contrast icons which improve the user experience for users needing improved contrast.
This release also makes available the AEGIS-funded GNOME Shell Magnifier. This magnifier…
I understand that a resource with X-Robots-Tag: noindex forces some search engines, including Google,
not to index the resource further. I also understand that an HTTP 301 response causes search engines to use the redirected URL instead of the original URL to refer to the resource.
But what happens if both…
I'm attempting to drive my user interface (heavy on javascript) through selenium. I've already tested the rest of my ajax interaction with selenium successfully. However, this one particular method seems to be eluding me because I can't seem to fake the correct click event. I could solve this problem by…
I've just updated Java from 1.6 to 1.7 via the Software Centre - removing the old Java 1.6 and selecting the new Java 1.7.
Firefox works fine.
But when I use Google Chrome to access a Java test website it says the Plugin is out of date. I click on run anyway and it says that it's running version 1.7.

We did a frontpage update some days ago that caused the site to crash. The site was down for several hours. After troubleshooting, we concluded that we needed to cache more content. It had been run too many queries.
After solving that and rebooting of server, we here in Sweden and Norway were again…
A few years ago I was speaking at a conference in Raleigh, NC where Ted Neward and I found a fun way to promote a Java vs. .NET debate that was planned one evening. We stood in the middle of a crowd during one of the breaks and starting “arguing” about Java vs. .NET with one another. Our voice…
I have a tree-like datastructure of some six levels deep, that I would like to represent on a single webpage (can be tabs, trees; ....)
In each level both childnodes and content are possible. Presenting it like a real tree would be not very usable (too big).
I was thinking in the lines of…
I have something scrolling in and out of the screen. Now when it goes off screen, I want it to scroll into the screen at another location. What I do is I grab the last pixels at the screens edge using g.copyArea and then g.drawImage on the edge of the screen. And then I do a g.translate to…
Ever since Google revamped their Analytics interface I've been noticing a weird "bug" while viewing the "Real-Time" overview area. From this area I can obviously see live stats of visitors to my website but when I visit my website by opening a new tab (Chrome) and manually visit website…
I have masterdomain.com which is the domain that hosts other domains.
On cPanel normally you can get to the actual cPanel by visiting cpanel.hosteddomainA.com, hosteddomainA.com/cpanel or hosteddomainA.com:2082
What I would like to accomplish is to have the hosteddomains cPanel auto…
I recently upgraded from 10.10 to 11.04 then 11.10, and I'd like to revert back to 10.10. I understand that you cannot downgrade a version as easily as you can upgrade, and that I'll probably have to get the boot CD again and reinstall the whole thing.
I know that I can keep most of…
I had a friend in college who programmed something that worked the first time, that was pretty amazing. But as for me, I just fire up the debugger as soon as I finally get whatever I'm working on to compile - saves me time (kidding of course, I sometimes hold out a little bit of…
