Fixing a dead Asus WL-500g
A short story with a happy ending: my Asus WL-500g locked up and it wasn’t starting, even after I hard-reset it (removed the power and plugged it back in). All the LEDs were constantly on (normally, when you plug in the power, they should light up for a second or so and the turn off).…

Computing the last digit of b^e efficiently
Geek PSA: Yesterday was PI day (3.14, get it?). Lets celebrate with this spiked math comic: Last week I saw the following problem which peaked my interest: Compute the last (decimal) digit of 2 raised to the power e where e might be very large.

In praise of Regexp::Assemble
…and of the Perl modules in general. I had the following problem: Given a list of 16 character alphanumeric IDs, find all the lines from a large-ish (~6GB) logfile which contain at least one of the IDs. The naive approach was to construct a big regular expression like W(QID1E|QID2E|QID3E…)W and match it against every line…

Funny pictures post 🙂
About DRM (this is floating around the interwebs, I’m not entirely sure about its origin): The second one is from a webcomic (added to my reader :-)) which I discovered via Bruce Schneier’s blog: And finally, for all the programmers out there (found it via The Reinvigorated Programmer’s blog):

RegEx which matches strings not containing a substring
This is an interesting problem which can appear in certain cases (although not very often). A little searching around led me to many posts stating that there is no easy solution and the following easy solution: ^((?!my string).)*$ It works as follows: the matching string must contain zero or more characters which are not preceded…

Java import statement gotcha
There is a lot of debate on the intertubes if one should or shouldn’t use wildcard imports. I’m mostly indifferent to the discussion (mainly because all the package references are resolved compile time – so there is no performance overhead – and because today’s IDE’s contain a lot of smarts to help you figure out…

FindersUK review
Finding relatives was always a topic which interested me marginally, so I was interested in checking out the Finders UK website (which BTW, can also be read in other ways because URLs don’t have the concept of capitalization implicitly – lets just leave at that). They offer different services like tracing heirs. Unfortunately (for me)…

BrickHouse Alert review
After looking at the site of this Medical Alert company I’m left with troubling questions in my mind. Having an ill grand-parent makes me acutely appreciate the need for Medical Alert services, but this company leaves many open questions, especially considering the fact that this is a company which requires a monthly subscription. Their site…
