Gammu documentation improvements

During the weekend, I've found some time to improve documentation for Gammu. One of user accessible things which did lack documentation are native file formats used by Gammu.

There is not that much of them as Gammu supports standard formats for most data (like vCard, vCalendar, iCalendar), but there are things where standard simply does not exists and we need to store that data as well. This is the case for backups (both data and SMS), where SMS backup format is used as well for files backend in Gammu SMSD.

So I went through the SMS backup internals and wrote the documentation. While reading the code I of course discovered quite obvious bug, which was for some reason undiscovered for very long time.

Call for Wammu translations

I'm about to release new Wammu version in one or two weeks, so it's best time to look at the translations and improve them. There is not much new messages since last release, but only few translations were complete back then, so virtually any language (Czech and German are the only ones complete right now) needs improvements.

To translate you can simply use web interface:

Looking for VServer alternative

It seems like VServer is not something for long run because it does not seem to want to be upstream and there is also no good future for having it as patch in Debian for long run. So I should look for alternatives and probably migrate to some other solution while upgrading my server to Squeeze (once it is released or really close to the release).

There are various options, starting with OpenVZ, through Linux Containers (LXC) up to full virtualization (probably KVM based). With OpenVZ the situation won't be much better, so it is not a real option. For various reasons I don't want to go to full virtualization, I simply thing containers are good enough and avoid too much overhead in some situations.

So the only remaining solution seems to be LXC. There even seem to be some people who managed to migrate from VServer, which is good and will be definitely helpful. Now it's time to play with lxc a bit before I will try to implement it for real.

Gammu gets m-obex support

I've found some time to implement m-obex protocol based on documentation provided by samsyncro project. However I don't have any phone to test it, so any testers are welcome :-).

The testing should be quite easy - just get current Git version of Gammu (either using git or use snapshots) and try to use commands which manipulate with contacts and calendar:

gammu getallmemory ME
gammu getallcalendar
gammu getmemory ME 1
gammu getcalendar 1
gammu addnew test.vcf
gammu addnew test.vcs

In case you have not yet used Gammu with your phone, the configuration for USB cable should look like:

[gammu]
device = /dev/ttyACM0
connection = at

And for Bluetooth:

[gammu]
device = address of the phone
connection = blueobex
model = mobex

Of course there is no guarantee that any of the commands will work, because all I could verify is that code compiles and looks correct. It might as well do something bad to your phone, so backup is recommended.

Changed website

After last fixes during yesterday evening, I've decided to put new website online today. It matches layout of my blog, uses same technology underneath (Django).

The biggest change is probably simplification of the structure and also cleanup of old unused stuff. I tried not to miss anything, but I'm sure something will be discovered in next days.

With this change, I've also shutdown my SVN server as all things has been migrated either elsewhere (usually Debian's collab-maint SVN repository) or are now using Git either on Gitorious or repo.or.cz.

What things to flattr?

With increasing popularity of Flattr (114,057 € has gone through the Flattr system in two months), several people start to recommend what things to flattr. I'm not going into this business, however they seem so find interesting things for me so you might like it as well.

The Flattr Free and Open Source Software by Raphaël Hertzog is actually thing which has attracted me to the Flattr. It collects recommendations how to tag your free software on Flattr and each month it publishes five recommendations which projects to flattr.

The other thing I've noticed is list made each month by Evgeni Golov, which I've mostly noticed because increasing popularity of phpMyAdmin on Flattr, because he was really fast in advertising it :-).

Migrating documentation to Sphinx

While working on my new website, I've decided also to put documentation for Python modules into more pleasant format and use Sphinx for that.

As it can include docstrings automatically and writing text in rst is really easy, after few minutes, the photo-uploader documentation got migrated to photo-uploader manual, which indeed looks nicer that old man page + epydoc generated stuff.

Cleaning up the web

After recent switch of this blog to Django, I've also planned to switch rest of my website to use same engine. Most of the code is already written, however I've found some forgotten parts, which nobody used for really a long time.

As most of the things there is free software, I don't like idea removing it completely, however it is quite unlikely that somebody will want to use these ancient things. Especially when it quite lacks documentation and I really forgot about that (most of them being Turbo Pascal things for DOS, Delphi components for Windows and so on). Anyway it will probably live only on dl.cihar.com in case anybody is interested.

Flattr for phpMyAdmin

The phpMyAdmin thing on Flattr has been around already for some time. I just created it together with other my stuff and somehow did not find time to discuss it with other project members and push it to our website. Despite this fact it got some attention and even recommendations.

Today, being pushed by Linus Olsson from Flattr (who just forwarded questions about authenticity of phpMyAdmin on Flattr), I finally find time to get an agreement from other project members and placed the button on phpMyAdmin's website.

Let's see how popular it will become now :-).

Drizzle on phpMyAdmin demo server

I've just set up another database to phpMyAdmin demo server - Drizzle. At first attempt phpMyAdmin did not work at all, but after few fixes (basically disabling all charsets/collation handling we do on connect), we're at least able to connect and show the interface with some databases and tables.

However there is much more things to fix (for example phpMyAdmin does not see all tables for some reason) and definitely more to test. However the question is if we want to officially support Drizzle and put some effort into it.

You can try phpMyAdmin with Drizzle here: http://demo.phpmyadmin.net/master-config/?server=3
