Debian: network not working after suspend
The problem:
When resuming from suspend, the network connection is lost. This happens whether using network-manager or /etc/network/interfaces. My network interface is Realtek r8169 (I found this with lsmod).
In /var/log/pm-suspend.log, I get the following message:
/etc/pm/config.d/unload_modules: SUSPEND_MODULES: not found
Solution:

- Install packages acpitool and firmware-realtek.
- Make sure the file /etc/pm/config.d/unload_module exists, and add this line:
SUSPEND_MODULES="r8169"

Eclipse - ActionBarSherlock
To get ActionBarSherlock examples working in eclipse:
- Download ActionBarSherlock (ABS) .zip or .tar file and unpack it somewhere.
- First import the library project with: File → New Project → Android → Android project from existing code.
Select the "library" subfolder of ABS as root.
Tick "Copy projects into workspace" checkbox.
- Then import the samples project with the same steps above, using "samples/demos" subfolder as root.
- If you get "Call requires API level XX (current min is X)" errors:
- Go to Project Properties > Java Compiler. Use JDK 1.6.
- Ensure you're compiling both the library and your app with Android 4.0+
- Ensure you're targetSdkVersion is 14 or higher.
- Then, if there are some errors remaining:
- Right click on project -> Android tools -> Clear Lint Markers.

Restart X (ctrl+alt+backspace)
The ctrl+alt+backspace key combination that used to do a hard restart of the X server has been disabled in many distros. This functionality can be achieved with the combination:
AltGr+Sysrq+k
Where Sysrq is the same Print screen or Prtsc key.
Also, the old ctrl+alt+backspace behaivor can be restored by following the instructions in https://wiki.archlinux.org/index.php/Xorg#Ctrl.2BAlt.2BBackspace_does_not_work.

Resize image to huge resolution with imagemagick
Recently I needed to print a 5-megapixel photo to roughly 1x2 meter size; the printing store wouldn't print it unless the resolution was at least 300 dpi, which, at that size, means a resolution of 500-megapixels!
Unfortunately, most image editing programs won't support so big files. One solution is to use ImageMagick from the command line. This should work in any platform supported by ImageMagick: Linux, Unix, MacOS and Windows.
First donwload and install ImageMagick from http://www.imagemagick.org.
From a terminal window, type the folowing command:
The details of the different options can be found at http://www.imagemagick.org/script/convert.php, in short:

From a terminal window, type the folowing command:
$ convert -monitor -limit memory 1GB -filter triangle input_file.jpg -resize 1000% output_file.jpg
- convert is the ImageMagick tool that can (among many other things) resize images.
- -monitor is an option to display the progress of the operation. This is important to know what's happening, as the process may take several minutes.
- -limit memory 1GB. This limits the amount of memory used by ImageMagick Without this, the file failed to save!
- -filter triangle. This tells ImageMagick to use bilinear interpolation.
- 1000% was the resize factor I needed to produce the 300 dpi image at 1x2m, you can specify other percentage, different horizontal and vertical factors or a target width or heigth (or both) in pixels.

Vibration units conversion
To convert sinusoidal vibration amplitude units, you can use the online calculator at:
www.cbmapps.com/appshelp/8
It handles displacement, velocity and acceleration; in mil, µm, ips (in/s), mm/s, ft/s², m/s², g; expressed in peak (pk), peak to peak (pk-pk) or rms amplitude values.
