Automating ssh logins

I found this cool technique to automate ssh logins from
http://www.debian-administration.org/articles/152

First create a key pair

username@host:~$ ssh-keygen -t rsa

Then copy the generated key to the remote host machine.

ssh-copy-id -i ~/.ssh/id_rsa.pub username@remote-host

Great Latex editor for Windows

I came across latexeditor.org(LeD editor) which is probably the best editor for Windows. It has features which are distant from editors like Tecnix Center, some of them are
-> In-build DVI viewer
-> Support of bibliography and reference autocompletion
-> Support for scientific dictionary and thesaurus

My only complaint is that it looks unfinished. Also the word wrapping does not seem to work correctly when reusing the tex file in Kile later.

Finance managment for UK residents

I came across this very useful online financial tool called www.kublax.com for UK financial institutions. This is a welcome alternative like buxfer.com and mint.com.

2D/3D visulaizing tools

I am trying to understand positioning in 3D and was looking for some simple ad free tools to understand how things work in positioning algorithms.(Or how to visualize the positioning)

I came across some really fascinating software:
Archimedes Geo3D - probably the best software out there for 3D visualization
Geomview - allows one to manipulate images in it as output from other software.Has a messy installation though (could not install it as openmotif could not be successfully configured on my Ubuntu machine)
GeoGebra - free java based 2D geometry software.
