One may have noticed that right now my rejourn tree is empty. That’s not an accident, after Ram accepted my 15th patch, finally the site runs an unpatched version of rejourn - of course with a custom config and design.
Of course I still have a few ideas on what to improve, so this is not the end of the story, but still - I’m happy he was so open for changes and new features that we reached this post. :)

I usually just download the gpx track from my GPS and delete the track from device each time I arrive home and I was at some interesting place before. Last week this was not the case, I was at Gyúró two weeks ago, then I borrowed by device, without clearing the log from it.
So the task was easy: I had a timestamp and I had the full log from the device, and I want to split it: before and after a given timestamp. It turned out that I had some log from Oct 28th as well, so I wanted:
The log till Oct 28th
The log between Nov 5th and 8th
The log after 10th.
Luckily the gpsbabel documentation is quite clear in this area (see Example 4.8), I just needed the following commands:
$ gpsbabel -t -i gpx -f in.gpx -x track,stop=20101028 -o gpx -F out1.gpx
$ gpsbabel -t -i gpx -f in.gpx -x track,start=20101105,stop=20101108 -o gpx -F out2.gpx
$ gpsbabel -t -i gpx -f in.gpx -x track,start=20101110 -o gpx -F out3.gpxUpdate: two more notes:
the stop is exclusive, start is inclusive
when using the result in digikam, the camera time zone has to be set to "manual: gmt+0", even if both the gpx result and the camera time is in local time

Once I was ready with this year’s GSoC work I started to submit it back
to OpenOffice.org. Before that was completed, LibreOffice was launched,
though I thought if I started working on submitting it to OpenOffice.org
as well, I’ll finish it. About 6 weeks later they now
integrated
(merged) the vmiklos01 CWS (the branch containing my GSoC work) to
DEV300, what will became OpenOffice.org 3.4 later.

The whole story starts here. The whole conflict is about I had a google account with my vmiklos.hu domain already, but now the google apps account took it over and they asked me to rename the old account to something else.
I joined the early adopter program and I was happy about it, finally I could access Picasa with my google apps account, though I could not make it to picasa.vmiklos.hu or something. But at least I could use it.
Why I’m writing is that now they changed something regarding google groups as well, since I just noticed I can no longer post to the invite-only lists hosted on google groups where I use my personal address… It turns out the trick is to get the old (renamed) address unsubscribed and get the new one subscribed.
I’m not really claiming, since the new state is much more clear, but this unsubscribe + subscribe dance is rather uncomfortable…
Oh, and a related doc link in case you want to use gtalk on your domain as well (for now I decided not to use it).

So we had this script with Jonas, and the current news about it is that it’s mentioned by in this LWN article. I just innocently read the article and noticed:
After ten years, the code still has over 100,000 lines of German-language comments; those are now being targeted with the help of a script which repurposes the built-in language-guessing code which is part of the spelling checker.
Nice! :)

Even if I gave it a quick testing about two weeks ago, now I tried the new Twitter / identi.ca support and I like it a lot. Now messages are not coming from a single user by default, but a separate channel is created, nicks are appearing there, and I can just highlight people to reply to their last tweet or simply type to submit a new one.
And of course my Skype module still works, as Wilmer fixed it up. :)

Today I packaged tgt an iSCSI target (server). The upstream package provides a large number of examples, though I thought it’s a good idea to note what I used for testing:
# egrep -v '#|^$' /etc/tgt/targets.conf
default-driver iscsi
<target iqn.2010-11.local.test:storage>
backing-store /dev/sdb
</target>Something offtopic: a rejourn patch accepted and a LibreOffice bug fixed today.

Today I had some Hungarian mathematical logic notes to type in Latex, and again I had to dig up the various references to get the proper symbols I needed.
I used the following pages:
amsmath is unique
in that for example it explains how to use \begin{cases}
this one is
a collection of lot of symbols, I found \mathcal here
An article from Wikipedia about logic symbols
The Math chapter of the well-known LaTeX wikibook
A set of macros making easy to declare lemmas, definitions, proofs.

The problem was the following: I had this
example code and the size() method just gave me insane result all the
time, while just changing the driver to QMYSQL made the code work
properly. After asking on #qt, I have been
pointed out that the SQLite backend of
QtSql does not support the size() method. :/
So - for now - I’ll just use MySql for my unit tests, even if that means I have to manually truncate the contents of each table. Worths checking a bit later again, though - since I already used in-memory SQLite for my unit tests when I had a project in PHP with Doctrine, and it was working just fine.
