Since yesterday was pay day I decided to spend some money. My bike got equipped with a brand new crankset and chain, much needed, and today I bought some new shoes, a couple of ECCO Receptor, with lots of ventilation in preperation for a warm summe :). Unlike that other time, you will have to settle for the picture at the ECCO page :). Tonight Mikoline and I are going to visit Brian to get some nice food and help him consume some of his wast amount of cheap imported german beer (well, it is danish beer, but it was imported from Germany). See ya.

More Free Food
I have just returned from the birthday reception of Ivan, there were lots and lots of free food and good company, very nice :).
In other news, Allan and I were told by Gerth yesterday that we have received student travel grants to go to SWAT 2006 in Riga in July. In preparation for all the flying I will be doing this summer I signed up for the EuroBonus program at SAS, I hope to accumulate some tax-free frequent flyer points :)
Messy References in Research Papers
I was just reading through the paper “Cache Oblivious Distribution Sweeping” By Gerth and Rolf. That paper refers some details and applications of the distribution sweeping algorithm to the full version of the paper which it claims is in the BRICS Technical Report RS-02-18. So I look that up on the BRICS homepage and see that this supposedly full version is one of the only papers in the technical report which is not available online directly. It states that the paper is in volume 2380 of the Lecture Notes in Compute Science at Springer. These notes were not readily available online, so I walked to the computer science library which is near my office and find the notes, locate the article in the table of contents and go to it. My worst fears were then realized as I noted that It was the exact same article I already was reading, so I had just follow a cycle and the paper referred to itself (albeit in a somewhat tedious way). Well, maybe not, but it is still annoying. Maybe they decided not do to a full version anyways.
[Update] I did eventually find the pape, I just needed to improve my paper searching voodoo skills :)
Point Of No Return
The tickets are now booked. My summer plans are now set in stone from from the 16th of July to the 26th of August, more info will come when I actually feel like making a longer post :)
Tagging With F-Spot
Inpired by Lars’ excellent photo tagging, I have decided to shine up my photo collection. Since mono is much more integrated in Fedora Core 5 I decided to try and use of the fancy new C# applications I have been reading so much about. I had already read some good things about F-spot so I decided to try that out. I downloaded it easily using yum and started it up. F-spot has a very nice GUI and I had quickly imported about 1800 photos into it. Importing photos however, is a small part of the job and I have now embarked on the enormous task of tagging all the pictures. So far I have 32 different tags, and that number keeps increasing as I tag more and more pictures. When I have tagged all of them I have some more pictures still waiting for processing :). This is tedious work, but it should be easy to keep update when adding new pictures. I really like the concept/idea of tagging pictures since I can use all the tags I want, it is a much more convenient way of working compared to just having the pictures organized in the ever-so-common “albums” where you have to limit the pictures to a single album.
F-spot can export its database to varius web based formats, but do not expect to see all my pictures online anytime soon. First I need a place to put them (it’s more than one gig) and I might need to apply some censorchip as well :)
GNUPG (GPG) Secret Key (secring.gpg) Recovery
I have been trying to recover some of the data from my formatted partition these past days. Since the partition has been formatted I have given up on ever recovering the emails and other kinds of data with non-trivial file layouts. I have instead focused on recovering the secret key to my gnupg public key for one of my email addresses. By playing with hexdump on secring.gpg files gnupg generated for me I found that these always started with two octets (0×01, 0×95). I then made a simple scanner scanning the device (/dev/hda6 in this case) for these octets. Each time this header was located it was written out with the following bytes making a bunch of small files of 4000 bytes. I then wrote a bash script using a simple truncator program I wrote to actually run gpg –import on each of these candidates truncated to all lengths between 100 and 4000 bytes.
However, I was unable to recover anything :|. I had already filled around 2 gigs of the 16 gigs making up the partition and by doing that I might have owerwritten the key data, bollocks.
