I love watches. 
Being a techie, I really can’t accept a watch that isn’t accurate. The accuracy of a quartz-crystal based watch is the minimum. I wish I could get a Rolex, Omega or other really nice looking watch, but I just can’t accept the accuracy I’ll get from a watch like that. So all the beautiful Swiss watches are out for me. But there are alternatives:
I’m currently taking a Cryptology course at Stanford University via Coursera. It came recommended by Bruce Schneier on Security: Free Cryptography Class, and I find it a great way to expand my knowledge. I really appreciate the level. Just enough for it to be challenging and stimulating, but also not too hard or too much work, so I can still fit it in with family and work.
And in addition, the courses are free!
Thanks, Coursera and participating universities for making this possible.
Check it out! There are courses in:
All provided by professors from top-notch univerities in the US.
I’ve only tried the Cryptology course, but it rocks!

I’ve written before about how to access SNMP agents (or other TCP or UDP services) in a network when you only have SSH access. Running a SSH VPN and then running IP Masquerading (NAT) in the remote end is the solution for me so far. Here is how it is done.
I’d like to recommend an Android App for seeing the Sun’s path in Augmented Reality (AR): Sun Surveyor. There is also Sun Seeker for iPhone/iOS, which I haven’t tried since I don’t have an iPhone.
We’re out looking for a house to buy, and for me getting the afternoon and evening sun on the terrace during summer is so incredibly important. This way, I don’t have to take the real-estate agent’s word for where the sun goes down in the summer and whether the trees will create shade on the terrace. I can check it myself. Über-cool!
The graphics are laid out on top of my phone’s camera image, so given the image to the right I can see that on July 9th (almost mid-summer) the sun clears the wall just after 7pm before it goes down at 8:52pm. A little before that it will be obstructed by the wall in the background though. All visible on one screen.
I guess this could be handy for photographers too, but for buying a house this is indispensable. What surprises me is how all the real-estate agents that I’ve shown it to were blown away by it (or so they pretended 
) but had never seen or heard about something like that before.
Have fun with it!
Honestly, I don’t understand how somebody can prefer PDF to HTML for on-screen viewing. Really? That is possible? If you’re one of them, can you help me understand?

Here in Denmark, we’ve just had an election, and the previous government has been replaced.
A newspaper article [lang="da"] looks back at what people liked and disliked about what the previous government did.
I have trouble believing, much less understanding, that 68% consider increased surveillance to have had a positive effect for Denmark, 16% believe the effect to be neutral and 16% believe it to be negative.
Wow. The people who believe that our society is better off when the government monitors us more out numbers people like me 4 to 1? Yikes. Has nobody read 1984 or seen Das Leben der Anderen? Doesn’t anybody remember DDR or the Soviet Union? Perhaps China will open source the great firewall too, so we can install it here!
I’m a little sad today about this.
Edit on 2011-10-20. Oh no, it keeps getting worse [lang="da"].
NSA proposes Accumulo NoSQL database to Apache, writes The H.
This is a big deal (at least in my book) because it demonstrates that the NSA does not believe in security by obscurity.

Really cool list of 34 Cleverly Designed Inventions. I especially liked the USB connector, the stair case drawers, and the crawling lamp on the wall.
Thanks to the Userfocus Usability Newsletter for the link. The site also has lovely 32 Pictures To Help You Appreciate The Awesomeness Of Nature but I better let you go now .
A Danish Minister approves an ad-agency to pose as real users and stuff a forum with bogus posts to kick-start it. I’m appalled, surprised at my own ignorance and worried about the lack of credibility of even government-funded sites. Continue reading ‘How much do we trust posts on website forums?’ »
Why doesn’t every programming language have “Natural Sorting” built in, out of the box? Natural sorting is the way humans sort, where number substrings are sorted numerically, everything else alphabetically:
| Sorted “Asciibetically” (normal computer sort) | Sorted “Naturally” (what humans prefer) |
|---|---|
| foo1bar foo10bar foo2bar |
foo1bar foo2bar foo10bar |
Notice how 10 comes before 2 in asciibetical “normal computer sorting” ? Haven’t we all seen user interfaces that like that? Its just plain wrong. 
Dave Koelle’s Alphanum Algorithm sorts naturally, but instead of analyzing each array element O(log(N)) times, I present a modified Perl version that allows for Schwartzian transforms, yielding huge performance improvements.
