Lecture notes on the work of Einstein and physics inspired by Einstein’s work:
The course is aimed at people who have a strong sense that what Einstein did changed everything. However they do not know enough physics to understand what he did and why it was so important. The course presents just enough of Einstein’s physics to give students an independent sense of what he achieved and what he did not achieve.

Interesting article over at Linuxconfig.org:
This article describes a simple way on how to create a home made debian package and include it into a local package repository. Although we could use a existing Debian/Ubuntu package, we will start from scratch by creating our own minimalistic unofficial debian package. Once our package is ready, we will include it into our local package repository. This article illustrates very simplistic approach of creating debian package, however it may serve as a template in many different scenarios.

It’s only logical, but I hadn’t really thought about it much. Turns out Regular Expression can be vulnerable to external Denial of Service attacks.

Just found this out: You can easily add all the holidays for your country (or particular religion) to your Google Calendar by going to: Other Calendars → Add → Browse Interesting Calendars. There you can subcribe to calendars containing your country’s holidays.

A while ago I fiddled around with my Vim configuration, and I removed some things I thought weren’t necessary. A little while later I noticed that, when I copied things in a terminal Vim by selecting them with the mouse or a normal visual selection, I couldn’t paste them into other X11 programs such as the terminal, Firefox and other Vim instances. Of course, I didn’t have a backup of my old vimrc.
After much fiddling around with the various guioptions, mouse and clipboard settings, and many a Google search, I found a page which offered some insight:
For this to work, your Vim has to be compiled with the +xterm_clipboard setting. Run
vim --version | grep xterm_clipboardto see if that option is compiled in
My Vim (Xubuntu 10.10) showed -xterm_clipboard instead of +xterm_clipboard meaning it didn’t support directly cutting/copying to the X11 clipboard. It turns out that I had removed the vim-gtk package and installed the normal vim package, since I never use the GTK/Gnome version anyway.
Re-installing the vim-gtk package solved the problem:
aptitude install vim-gtk
If you want to be able to select with the mouse, you will also need to set the following in your ~/.vimrc:
set mouse=a
If you don’t have that you can still select with the mouse, but it won’t be Vim who does your selection but your terminal emulator. That results in line numbers being included in your selection (if you’ve set number) as well as lines longer than the terminal being cut off.
Update: Imran Chaudhry mails to say:
On Debian Squeeze which I’m using I have to re-run the alternatives method so that vim finds the right vim:
$ update-alternatives --config vim
Thanks, Imran!
