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:

1. Install packages acpitool and firmware-realtek.
2. 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:
  1. Go to Project Properties > Java Compiler. Use JDK 1.6. 
  2. Ensure you're compiling both the library and your app with Android 4.0+ 
  3. Ensure you're targetSdkVersion is 14 or higher.


• Then, if there are some errors remaining:
  1. 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:

$ convert -monitor -limit memory 1GB -filter triangle input_file.jpg -resize 1000% output_file.jpg

The details of the different options can be found at http://www.imagemagick.org/script/convert.php, in short:

• 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.

Raspberry Pi: terminal "ls" colors for root in bash

To have the "ls" command output shown in colors for the root user, add the following line to the /root/.bashrc file.

alias ls='ls --color'

Note that, depending on the distribution you are using, this line (or something very similar) can already be present but commented out.

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.

or (works for other distros, too):

$ cat /etc/issue

Batch convert youtube flv files to .mp3 audio (linux)

The following command will convert all .flv files in a directory into .mp3 files (keeping the filename). Make sure you have ffmpeg installed.

for i in *.flv; do ffmpeg -i "$i" -ab 128k "`basename "$i" .flv`".mp3; done

You can replace 128k with another bitrate. Keep in mind, however, that the conversion won't improve the quality beyond that of the bitrate of the original audio track of the .flv video file, which can be found with the command:

ffmpeg -i filename
