I'm using Glade and Anjuta to build an oscilloscope and wanted a dial like a real scope, so I sub classed a VScale and painted my own dial.In the process I lost the ability to move the dial.I' ll have to implement the interface from scratch like I started from a base Gtk::Widget.Is this the way it is, or are there ways to change visual appearance of the VScale and still keep it reacting as a VScale?

Does anyone have an example of a way to use ImageMagick or GIMP to Auto-White-Balance and scale 50% as a shell script? I'm asking because I usually do this to post-process photos in GIMP but being able to do this in a shell script means I could put it in Thunar in Xfce and save myself quite a bit of time.I checked the man page of mogrify and convert and didn't see any auto-white-balance type options that I am aware of

I am a C++ programmer and never used Perl. add a functionality to a script, in Perl language. Originally, the script takes 1 file input and I run it in this way: ./script.pl file1 It is designed to return specific words from that file, example:
user
admin
printer-1
user-2
server
The idea is that I need to be able to provide the script with a second input file that contains only few words, each on a new line. These words might have a "dash". Example:
printer-2
server
user-2
I will be running the script as: ./script.pl file1 file2 In return, the script should check if every word in file1 does exist in file2. If it does exist, then the script displays it. In the example I provided above, the script should only return:
server
user-2
Here is the script I have. What's in black is the original working Perl script and what's in red is what I would like to add in Perl Language:
!/usr/bin/env perl
my ($table);
for (every value in file2)
{

The problem started with that I got a lot of errors about missing header files included from SDL_mixer.h when I attempted to compile my projects. I looked in the directory of this file, and all header files were missing except SDL_mixer.h Resolved this by compiling and installing the base SDL library package. Programs that got recompiled and were able to play music before suddenly produced no music, but sound effects worked. However, old binaries that were compiled prior to the issue with the missing header files played music fine. What the heck is this? I get no errors, nor warnings; none at compilation, none on execution. The kernel pool (dmesg) is clean. There is also another strange issue, which perhaps has nothing to do with the first issue. x86_1$ ./fire XDM authorization key matches an existing client!Couldn't initialize SDL: Couldn't open X11 display.

View 6 Replies View RelatedI have an issue with network-manager. When I edit my wireless settings and enable 'Allow all users' (I have a german locale so I don't know the exact words but I guess it's close enough) the connection drops and doesn't reconnect. If I click on the wlan access point manually (in the nm-applet) it asks for my WPA pass. This is odd since it was already in the wlan settings.
Then when I reset the 'Allow ...' to off, I'm asked for my su passwd and the connection is re-established. Ideally the nm would connect automatically at boot if the AP is available so I'm not happy with the current state...

View 4 Replies View RelatedI would like my CPU to be overclocked, while retaining frequency scaling capabilities. The CPU is a Core2 Quad Q6700, with a stock speed of 2.67 GHz. In my BIOS, I can manually increase the FSB, but if SpeedStep (EIST) is enabled, the increased FSB is ignored by Linux, and the max speed remains 2.67 GHz. If I disable SpeedStep, then the CPU successfully runs at the higher speed I would expect, but does not scale down when under low load. As it is now, I am only running it at 2.8 GHz.Does CPUFreq *require* SpeedStep to be enabled in the BIOS?

(I know it is a bit crazy)How would you structure a roll out?
two load balancers, two front end app servers, two database servers, and a cdn.And as traffic builds up, you would up the front end app servers, and maybe add two slave database servers? and maybe replicate the servers to east and the west to serve different parts of the world.What kind of hardware? I know it is a bit weird question, and it matters a lot on app, server hardware, server set up, style, class, lifestyle etc - I just want to see if there are any aha moments and awesome set ups that I am not aware of.

Is there a way that I can specify the height and with of the stream on the command line? From what I read, it looks like a #transcoder option would work, but I cant seem to figure it out. The above command is working, and I can view the stream, but it's extremely slow, and continuously freezes and buffers. My thinking is that if I can reduce the scale of the video.

View 1 Replies View RelatedHow can I get the scale plugin to show windows from all workspaces like I could before with 10.04 and Gnome?With Unity the scale plugin only "scales" windows that are on the current desktop/workspace.
View 4 Replies View RelatedI have a dual monitor setup and I've used Scale for a few days now, but I'm still confused about the expected ordering of the windows within the same workspace. For example, the last focused window isn't necessarily placed at a fixed spot, e.g., top left corner. It seems that if a window on my left monitor is last focused and I invoke it on my right screen, then it'd appear on the top left corner. However, if a window on my right monitor is last focused, it gets past just the last focused window on my left monitor. The last focused window on my left monitor eventually shifts to the bottom right corner.

Something that xine has no trouble with. I have tried the x11, sdl, xover, gl, and gl2 outputs which all make no difference. Am I missing an output, or is something not working as it should? In particular, why is xine fine, while mplayer stumbles? As an unrelated question, it is possible to set mplayer to skip to a next file in a directory? From what I could tell, it does not seem to have this functionality built in.
