SSH login: show load avg, free memory, free disk, etc.

For most any Linux computer (including Raspberry Pi, Beaglebone Black, Beagleboard, etc.) you can display a cool login message using a “message of the day” (MOTD) type framework. This code was modified from the original at: http://www.raspberrypi.org/phpBB3/viewtopic.php?t=23440 For now, I’ll have you put this code in ~/.bash_profile in case there would be any problems. On […]

AIDA tools

For those interested in working with data from ASK/ALIS or just seeing how some interesting 3D tomography works, there is a Matlab toolbox at: https://aniara.irf.se/svn/AIDA_tools/trunk/ or using Subversion, type at Terminal: svn co “https://aniara.irf.se/svn/AIDA_tools/trunk” AIDA_tools Installation: 1) cp ~/AIDA_tools/AIDA_startup.m ~/matlabTools/ (or wherever you keep your frequently used scripts) 2) edit this ~/matlabTools/AIDA_startup.m file and make […]

Matlab: Free memory on Linux/mac

Matlab’s built-in “memory” command does not work on Linux or Mac. Here is a simple function to check memory status on Linux or Mac: %Copyright (c) 2012, Michael Hirsch %All rights reserved. % %Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met: % […]

Winetricks “voice had cried out in terror” error resolve

if you get a winetricks error like: wine cmd.exe /c echo ‘%ProgramFiles%’ returned a string containing the word ‘unknown’, as if a voice had cried out in terror, and was suddenly silenced. You can fix it by doing the following 1) backup your existing system.reg file by typing in Terminal: cp ~/.wine/system.reg ~/.wine/system.reg.bak 2) gedit […]
