Figuring out coordinate system transformation
By thomas in geometryNotes on how to construct simple transformations between coordinate systems.
We have a coordinate system and another coordinate system
. To construct a transformation matrix allowing us to get coordinates,
which is expressed in coordinate system
expressed in coordinate system
a transformation matrix,
is required. This transformation matrix allow us to get
Lets say origo of coordinate system B in coordinate system A is {^A}O = [x1,y1,z1] and that the two coordinate system are otherwise aligned then the transformation matrix is:
If the systems are not aligned and instead B is rotated \pi radians around the y axis then the rotation matrix R^A_B is… It’s to cumbersome to create good-looking output… This post will end prematurely

adding formulas to google docs and presentations workaround
By thomas in google docs, latexA far from optimal workaround for adding formulas to google presentations and properly also google docs is to use
http://www.codecogs.com/latex/eqneditor.php
to construct the formula with latex syntax and load it as an image by adding an image from an URL E.g.:
formula generated by codecogs.com
The ugly drawback is that, AFAIK, you are not able to recall the link address and change your formula. But for at quick, one time workaround I think it works

merging when git conflict – setup and tools
By thomas in GITPossible merge tools: kdiff3 and meld
Setup kdiff3 in git
git config --global difftool.prompt false
git config --global difftool.kdiff3.trustExitCode false
git config --global diff.tool kdiff3
git config --global mergetool.kdiff3.trustExitCode false
git config --global mergetool.keepBackup false
git config --global merge.tool kdiff3
When forming a merge command the following variables can be used (This should however not be necessary if the tool is supported by git)
$BASE = a generated file that contains the common base of the two files
$LOCAL = file containing the content on the current branch
$REMOTE = file containing the content of the file to be merged into the local branch
$MERGED = the name of the file to which the merge result should be written
Resolving conflicts after merge: git mergetool
Inspecting diffs: cpgit diff

Dlink dir-615 rev. H2
By thomas in dd-wrtNotes collected when trying to get dd-wrt running on dlink dir-615 rev H2.

Getting client mode to work
Frst disabled security on main router. Then followed
http://www.dd-wrt.com/wiki/index.php/Client_Bridged
then added security on main router and client router (dlink dir-615) (WPA2-personal sec key: AES). Specifying AES on main router may bare been the crucial part.
