FritzBox!

Tuesday, June 23rd, 2009

Wow!

I received my FritzBox 7170 today, as a present from XS4ALL for renewing my ADSL subscription for another year (cheap deal — I would have done that anyway). And it totally blows away my Thompson Speedtouch!

Obfuscate your numbers!

Sunday, June 7th, 2009

Time for some silliness.

In a little over a month, I will be

years old.

What’s that, you didn’t get it? Here, I’ll repeat it for you in terms you may understand more easily:

At work, it has become a bit of a tradition that when people announce their birthday, they do so in an at least somewhat obfuscated format. Hexadecimal, binary and more obscure number formats are always popular, of course, as are silly descriptions of the form “my age is the ninth distinct biprime“. But last year I decided to take it to the next level, and write a little generator in Ruby for expressions such as the ones you see above. As you can probably guess, the expressions are generated using TeX.

You can play with it for yourself, if you want to, and also download the latest version of the code. But please be gentle with my server, as you can probably guess it’s a rather heavy application and I’m running this site on a little home PC..

Cool toy of the day: Nokia N810

Sunday, February 24th, 2008

My shiny new Nokia N810 Internet Tablet arrived this week, and I like it!

(Bias alert: my friend Dirk-Jan works for Nokia in Finland as a project manager on the N810, so that made me a little more interested in this gadget than I would otherwise have been.)

Firewall improvements from R. Scott Smith

Sunday, March 25th, 2007

In response to my article about using the recent IPTables module to fight brute-force password attacks, based on an idea from Andrew Pollock, a reader worked out the idea into a complete firewall script, with configurable whitelisting, the ability to block multiple ports, and several other enhancements. Read his post for the details.

You can download his firewall script here. You can contact the author at the address meetscott at the domain netscape.net.

Cool tool of the day: Synergy

Monday, February 5th, 2007

Synergy lets multiple machines share a single mouse and keyboard, and makes switching between them as easy as moving the mouse from one screen to another on a multi-monitor setup. Just move the mouse off the edge of the screen, and it enters the screen of another machine, taking the keyboard with it. It even manages the clipboard, so you can copy a piece of text on one screen and paste it into a window on another machine. It’s open-source and supports Windows, Linux and the Mac.

The config program could be more intuitive, but once it’s set up it works really nifty. It’s great for working on my laptop and desktop at work, or for switching between my Mac and my Ubuntu machine at home. Which is why I hereby give Synergy the official “recommended by Martin” award.
