Have you ever wondered how load average on Unix is defined?

• http://www.gliffy.com/ – a web-based “Flashy” Visio-like drawing program. A bit basic now, but I’m sure it’s getting there. Wonder when they will be bought by …
• http://www.google.com/googlespreadsheets/ – Spreadsheets from Google. Again, a bit basic, but quite impressive.

Proofreading my thesis I had the following problem: Find all occurrences of “alert processing system” (should be “alert-processing system”), which can span over multiple lines.

I found out (thanks Diego!) a number of ways of doing this.

1. Writing my own perl program and defining INPUT_RECORD_SEPARATOR ($/)

2. Using agrep, in which I can use -d ‘delim’ as the separator. The advantage of agrep is that is can also find mispelled words (with a certain editing distance).

3. Using pcregrep!

I chose the last solution as it is the simplest one:

pcregrep -Mi 'alert\s+processing\s+system' <file>

IT WORKS!

Two cool blogs about life hacking, productivity, cook gadgets and the like – a must have for a geek like me: http://www.43folders.com, http://www.lifehacker.com

A cool article on mistakes made in Xbox. Talks a lot about building (in)secure hardware/software systems (may be useful when looking at the TPM stuff).

Writing my thesis, I had to create a table with table captions located below the table. Without much thinking I looked at the Latex bible and read about three ways of doing it.

The solution I chose was to use a package `threeparttable’, which did exactly what I wanted. Here’s my code:

\usepackage{threeparttable}

\begin{table}[htb]
  \centering
  \begin{threeparttable}
    \caption{Caption.}
    \begin{tabulary}{\linewidth}{|L|C|}
      \hline a\tnote{a} & b\tnote{b} \\
      \hline
    \end{tabulary}
    \begin{tablenotes}[para]
      \scriptsize
      \item[a] Footnote a.
      \item[b] Footnote b.
    \end{tablenotes}
    \label{table:ml_requirements}
  \end{threeparttable}
\end{table}
