Travel agenda before FOSDEM

In last few days I spent some time with travel agenda. Tomorrow morning I am leaving for FOSDEM, so I'm arranging last minutes things like online checking. Whoever wants to meet me just drop me an email or just check things I want to visit and find me there.

Meanwhile got open registration for Debconf 10, so when I was in travelling mood, I also filled in that one. Right now it looks like it will be quite tough for me to pay this trip, but there is still some time to sort it out :-).

Gammu is being used in vendor software

I always thought Gammu to be workaround for phones whose vendors do not provide software for your favorite operating system. We try to do our best job to work with variety of phones, even though this is hard and never finished job.

However today I was really surprised to find out that some phone vendor built their official application for managing phone on Gammu. The application is of course closed source and available only for Windows, but this does not change anything on the fact they use it. They seem to have modified code slightly, adding some new functions and removing others, separated the code to several DLLs, however I'm 100% sure it is Gammu as they use some unique (read awful) things we have in our code.

I'm not going to disclose their name right now as I want to give them fair amount of time for reaction on my asking for sources. But you will for sure find more information later in my blog.

PS: Gammu is of course not the only free software used inside this application, you can find more there (and you will find there more than I did if you will look longer than few minutes I spent on examining rest of code).

phpMyAdmin 3.4 will be feature killer

I know this is quite premature as we're just about to release 3.3, however development on 3.4 has already started in SVN and we've already implemented more than 20 requests from our features tracker. This is even bigger number than release 3.3 will have!

Well the fact is that most of these things are cosmetic or tiny improvements, on the other side some of them were requested for very long time (the oldest one currently dates to 2003).

The new features bring things such as direct blob download (thing we definitely should have earlier), links to documentation for SQL commands in highlighted SQL (what was quite easy, but nobody requested such thing and I added the feature after seeing that Adminer does this), possibility to directly bookmark most pages or exporting user privileges. See ChangeLog for more detailed list of features.

You can try all new features on our demo server.

New security issues

I just published three new security issues on phpMyAdmin. They are not exactly something what you would call new as you can see from CVE ids and even from phpMyAdmin version which does fix them (none of them existed in 3.x branch and were fixed in 2.9.10 for 2.9 branch).

However they got assigned CVE ids recently what means that we should tell about them to our users even when we don't think these are that important. So don't be frightened of them :-).

Prague airport prices

Martin, Prague airport used to be (one of) most expensive airport for food and drinks prices. They recently reduced prices quite a lot, but I still think they fully qualify to be in the group of most expensive airports.

But it has great advantage that every other airport looks cheap for us. This is almost same as prices for taxi, which is also usually cheaper than in Prague :-).

Going to FOSDEM 2010

Some time ago we decided in phpMyAdmin team to create yet another team meeting (after five years) at FOSDEM 2010. It took some time, but now I should have all travel things arranged (thanks to my employer who sends me there).

So if anybody wants to meet there, just drop me an email and I will try to put you on my schedule.

Fun with processing patches from users

Once you release something what gets at least a little bit popular, you can expect to receive fixes in various strange forms. Since I started to use Git for Gammu development merging all these crazy things is much more easier.

The problem with these changes in past was that they are generally based on some random old versions (for example random daily snapshot). Now I just find the right place in history where to start (ChangeLog usually gives good hint where to search in the history), create branch and start to apply changes I received.

I worst case (like it happened today) the "changes" is whole tarball with different changes made to different files. Fortunately I recently found great git add -i, which allows me to pick whatever changes I want from the patch. When all this is done, all I need is to merge changes back to master and Git is usually clever enough to handle it.

PS: And yes, I'd really love if people would be able to send me series of patches, but it does not seem to happen in near future.

Photo uploader 0.8

It took some time since last Photo uploader release, but it's not dead an now comes new release. It mostly just fixes imageshack interaction and moves development to Git on Gitorious.

News in this release:

  • Fixed grabbing URL from imageshack.
  • Fixed defaults to not open browser.
  • Default to imageshack.us service.

Ubuntu bugs for second time

It looks like my post about bugs in Ubuntu has received a bit more attention than I expected for few lines of ranting :-). Most interesting reactions came to Lucas Nussbaum's blog.

There were nice explanations how it is supposed to work, but the problem is that people out there can not manage that amount of bugs. It is possible, that for some core packages, they manage to do the job. However most bug reports will probably go to some leaf packages, which are not that important, but lot of people use them.

I started to interest in bugs in Ubuntu when I noticed that there is some huge number of bugs linked on phpMyAdmin's PTS page. There was something like 50 too much bugs. After quick look I could see that most of them are duplicates. After little fight with ajaxy interface, I even managed to mark most of them as duplicates and fix it in Debian package. But as somebody with no knowledge of Ubuntu (and not willing to learn internals of yet another distribution, I think Debian and OpenSUSE is enough), I really have no idea what could be done to push some bug fix to existing release. So once some Ubuntu release (The Lucid Lynx in this case) got new version, I marked the bug as fixed. This is probably not that nice to users, but somebody from Ubuntu community should take care of them.

Off-topic PS: If anybody is interested in Google Wave invitations, just write me an email, I currently have 15 without any use.

Ubuntu bugs

For quite a long time I wonder, if there is anybody looking at bugs reported in Ubuntu. Whenever I look at bugs reported in Ubuntu on some of packages I maintain in Debian, there is huge amount of them. Most of them are simple duplicates, but still it indicates that nobody have looked at them. Some are simply something what should be forwarded upstream, while some are clearly packaging bugs, which I usually fix. However I think there should be somebody at Ubuntu side looking at them and forwarding them to right place...
