I’ve been invited to the first LibreOffice conference in Paris to give a short talk about this year’s GSoC work of mine: the RTF import rewrite in Writer. (Here are the slides.)

It also allowed me to allocate some time on hacking, including:

Thank you for the invitation, it was great fun!

I did not care about boot speed for a long time, since servers usually restarted only for kernel upgrades, laptops suspend to ram all the time, and I have no desktop machine at home for years now. Though one use case started to motivate me recently: I use virtual machines a lot, and waiting for them to boot up is boring.

So I looked at the systemd-analyze blame output, and it turned out that for a base-only install the only service that takes a lot of time is netconfig. It’s because it was a oneshot service, so the whole boot process waited for dhcpcd to get an IP. A much better solution is to just start netconfig in the background and move on — and that’s exactly frugalwareutils in git does now.

When we got back from Munich, Andras had an idea what is the current bottleneck with the build when there are a lot of languages enabled, and it was the po2oo script, which is part of translate-toolkit.

First I tried to optimize that script, but then I tried to do the same gettext-to-SDF conversion from scratch, without using that framework at all, and it seems that caused a drastic speedup.

There were a few iterations, but now the two patches are in master, along with a fix in fast_merge.pl, which was there since at least commit 654810b (2009-06-17). ;)

Hatarozottan emlekszem, hogy nem ez volt az elso alkalom, hogy Dobogokore mentunk bringaval, de ugy tunik idaig nem irtam rola.

8-kor talalkoztunk a Margit-hidnal Botonddal, majd Pomaz fele vettunk az iranyt, kozben utbaejtve egy Auchant reggeli celjabol. Az egesz turanak az egyik celja az volt, hogy osszehasonlitsuk eronletunket, ami szamomra pozitiv csalodas volt: gyakorlatilag a Ketbukkfa-nyeregig kenyelmesen jottunk teljesen egyutt, de a csucson is alig kellett varnom. A kis fahazban meg mindig u.az a neni arulja a sutiket, be is zsebeltem egy almas pitet, bar eleg bosszanto volt elfogyasztani a sok darazs miatt. Innen Pilisszanto es Pilisvorosvar fele vettuk az utat, majd a 10-es uton haza.

Pontos utvonal erre.

A kmora ezt merte: ido 4h22m, tav 89.81km, max 57.6 km/h.

We were in Munich during this weekend, and I think all of us had great fun, kudos go to the organizers! If you are curious, there is a growing list of features implemented during the event.

Update: Oh, and I forgot to mention that we (Andras and me) especially thank the FSF.hu foundation for funding our travel!

Tonight I worked on fdo#39337, and while the writerfilter-based RTF import filter almost handled the document in question correctly, the fonts were not correct.

It turned out that this was caused by the fact that RTF’s font table (a table where each row has an ID and it contains the font name, charset and other properties) does not require continuous ID’s (for example positions 0, 2, 3 are allowed, even if 1 is not set), but dmapper (the glue layer between the RTF tokenizer and the Writer UNO API) does.

I already sent the position of the entry to dmapper, but the position turned out to be ignored, so now I fixed the RTF tokenizer to send continuous ID’s.

A related improvement is that I just discovered the writerfilter::TagLogger::unoPropertySet() method, which can dump the properties of an UNO object, and now I’ve enabled dumping of shape properties, which can help a lot when something goes wrong there.

This is going to be like my mysql password set post, I got tired of looking up the docs all the time, so here it is.

If you have a host running kvm instances and you want to forward the TCP port $hostport of the host machine $host to a port $guestport of the guest machine $guest, then you need:

So I’m testing a ThinkPad T520 for about 3 weeks now.

My motivations were:

The official homepage is here, the exact model I got has the following spec:

What I did not test:

Driver support: every portion works with Linux 2.6.39 without installing any external drivers, except the out-of-core vga.

Notes:

Back in April I had the idea to merge my bitlbee-skype plugin to the main BitlBee project. The reason is simple: BitlBee does not really have plugins (basically my Skype plugin was the only one) and because of this, ABI compatibility was not guaranteed, so I usually had to rebuild or even fix it after each BitlBee release (though Wilmer was helpful in case I was in doubt). Today this is all past, the plugin is part of the main BitlBee repo I won’t make separate bitlbee-skype releases anymore. (Latest version of the code is here, bzr info here.)

I’m quite happy this little piece of software did not get lost, but now is in the hands of an active maintainer again. :) If you need help with BitlBee, ask on #bitlbee, at irc.oftc.net.
