As open as a fuel tank

Not happy with the limited information most F1 sites gave over the disqualification of B.A.R. Honda, I pointed Konqueror to the FIA site.

It has become one of my favorite sites in the last years. The provide really, realy nice live timing during race and qualifying. You can see laptimes, who goes into the pits, how often and how fast they have returned on the track.

The FIA has put up interesting reading material on their website: the report which contains a detailled description of Jo Bauer, he explains how they found out that the B.A.R. had an extra compartment which can hold extra fuel. This way they can race with less weight untill the pit stop and when you leave some in at the end of the race, you still have the minimum required weight at the end of the race.

Although I have no inside information at all, it would surprise me if nobody else is cheating in F1. Cars depend heavily on software which, for example, control the engine of the motor. It should not be to hard to add some software just before the start, which can be deleted after the start, or on any other moment during the race.

To detect these routines an endoscope can not be used, as was used in the fuel tank. But as teams will hide any software which is not fully compliant with the FIA, Openening the source of the used software will not be a solution.

It is now proven that a fuel tank is the best example of an open standard although you will probably never see the inside of a tank. FIA’s law.

digiKam 0.8

Today we, and we is in this case the digiKam crew, announced the second beta of digiKam 0.7.3. In a seperate branch we are really working hard at digiKam 0.8.

One of the difficulties we faced untill now is that we worked on the actual files on the disk, so when we want to sort on the exif-date of the images, it was really slow, we could not put that function into digiKam, which was really bad.

So we decided to work on that. Also we had the problem that having the albums and the tags on the left made it really difficult to navigate, tag, scroll back to the album on top, scroll back to the tags, etc.

Ok, before I continue, let me insert a screenie to show what we have now in that branch.

On the left we have implemented a navigation bar, this way you can easily navigate between the tags, albums and dates. Dates? Yes dates. It shows all images in the period you select. Good to get things in the right perspective again ;-)

We can now sort images based on exif-date. We store all dates in a database. This way we can display them really fast, but the challenge is to keep the database in sync with the items on disk.

But the branch is experimental. Things are not stable and far from finished, but I wanted to show you what we are working on. It is really great to work on and I can learn c++ in a very nice way ;-)

Renchi has made some more screenies here and here.And on this one you can see a custom date picker on the lower left corner. You c
