Cannot fetch Flickr photo (id: 5176466672). The photo either does not exist, or is private

Today Wikidot was off-line for about 5 minutes due to database operations blocking access to page revision table. We added a column to mark tag changes in page revisions. This took very long time unexpectedly (on the test server it was a quick operation and we do have a full copy of Wikidot database there). Also it caused SELECT operations on that table to block until the ALTER operation finished.

Wikidot service is up again and we don't expect any major problems.

BTW, what we did was a preparation to implementing a wish to store tag changes in revision data rather than relying on revision comments only.

Doing risky things can be a lot of fun. A solid dose of adrenaline, quick decisions, testing limits of your abilities and equipment.

The long story short, yesterday after work we went for little sight-seeing with my car. The day before I left all my recovery equipment at home (even including my air compressor), so we just wanted to explore the area of the Tążyna river and find remains of an old village.

Not only with work the man lives. Recently we have found a great way to kick back after our nine to five duties.

Most probably you have watched the marvelous Tron movie. Or at least heard about it. Either the original (which is considered a breakthrough in computer-generated special effects), or the remake (well, a cheap remake in our opinion).

Now, one of the most known scenes from the movie is the light cycle race. Fast-paced, state-of-art 3D effects (I am talking about the original from 1982) made us all want to ride such a vehicle.
