Thanks, I found them. For some reason I never actually noticed that there was a separate panel to expose all of the input controls. Temporary selective UI blindness?

Unfortunately it looks like...

I have a Realtek ALC888 in a project I'm working on. According to the datasheet (http://www.hardwaresecrets.com/datasheets/ALC888_1-0.pdf) on page 2 there's a "Software selectable boost gain...

My SSH server was running Xubuntu 11.10, with a 12.04 client. Any Qt applications segfaulted exactly the way you described, but it was intermittent. Sometimes they'd work, but most of the time they...

A bit of threadomancy, but I'm running into this exact issue with Xubuntu 12.04. Any Qt applications I try running over SSH (e.g. VLC, QtCreator), are segfaulting.

Did you ever find a solution to...

It seems slightly like overkill to change WMs/DEs to make something as simple as a bluetooth mouse to work.

Does anyone know what (if any) hidden folders in my home directory would contain stale...

I'm not. I do have the proprietary Nvidia drivers for my graphics card, but that's it.

Yes, I am having this exact same issue and was wondering about it too. The buttons just don't seem to do anything.

My Bluetooth mouse was working fine under 11.04 (Gnome 2), but I cannot get it...

I checked the themes directory, and the themes were present. I copied over the .gtkrc-2.0 file from a functioning installation, but that did not solve the problem.

Ultimately I just gave up and...

I've got a system running Xubuntu 11.10 that has suddenly developed problems running any Qt application. Last week they were working fine, the computer was shut down cleanly the last time it was...

Over the last few days my laptop seems to have developed a problem where the sound will randomly cut out. Without any warning the sound just stops. Rebooting or suspending to RAM and waking the...

Some people are simply introverts. Society seems to dictate that the "ideal" child is an extrovert; they're social, play with others all the time, speak up in class, etc.... But those traits tend...

Of course CUPS is installed.

Out of desperation I tried plugging the printer directly into the router and using it as a stand-alone network printer. That worked, and I could print in colour, but...

I've tried that, but the HPLIP driver does not show up when using system-config-printer, and the HLPIP tool requires that the printer either be a stand-alone device on the network, or that it be...

Everything on the Printer Properties panel:

Printing Quality: Normal
Color Mode: Color - use ICM color profile
Resolution: 1200x600 dpi
Page size: Letter
Media Source: Auto Source
Media Type:...

The printer prints in colour from WinXP, so it's not an issue with the printer hardware itself.

I have an HP Colour Laserjet cp1025nw, and I simply cannot get it to print anything in colour. It produces very nice, crisp greyscale pages, and that's it.

I have installed the Foo2zjs driver as...

The problem is that you are trying to store an integer in a char. "%d" in fscanf means you expect to read in a 4-byte integer. The argument should therefore be a pointer to an int.

"&frame[i +...

Unless you can give us a better description of what happened, and maybe even a code snippet or two, I doubt there's much anyone can do to help you. Descriptions like "the code was not executed...

Python is nice for quickly banging out prototype AI/computer vision problems. Unfortunately such programs often require large amounts of computation, and therefore sometimes run slowly when written...

Voting for the 2012 ICRA DARwIn-OP Humanoid Application Challenge is open. 11 finalists are competing to create the best new application for a humanoid robot. Popular vote accounts for 25% of the...

It may be that your webcam does not record the frames as a JPG. What kind of webcam are you using?




Do you have the OpenCV Java library installed?

Depending on what exactly you need the program to do you can use OpenCV to grab frames from the webcam and save them fairly easily. OpenCV is maybe overkill for just grabbing frames from a webcam,...

Have you tried using "?" to make the selection lazy?



reti = regcomp (&regex, "http://\\([^/]*?\\)/", 0);


I've never worked with regexes in C, but in other languages that works.

You can also use:



import subprocess

client = subprocess.Popen("/command/to/execute")


The subprocess module lets you do all sorts of useful things with programs you want to execute. ...

Think about array how you walk through an array in C. Do you use this loop:


for(i=0; i<=array_length; i++)
printf("%d\n",array[i]);

Or do you use this loop:


for(i=0;...
