Bruno got back to me and proposed a revised gettext-po.h, which looks much more interesting. I had a quick tidy-up of gtranslator HEAD to remove some old unsupported/unmaintained code, so I'm all ready to start using the new API as soon as Bruno has implemented it. Superb.

My first week's work for my newest customer went fairly well. However, due to a major 'half-asleep on a Monday morning' mistake, I accidentally wiped out glibc on my laptop, rendering it fairly useless. It's taken me until now (Tuesday evening) to get things sorted, but the upshot is that I got it running Fedora Core 2 instead of Debian unstable. I seem to have overcome the major hurdles, most of which involved trying to build a kernel that would work with the prism2_cs module.

Had a day out in London with my mum, dad and Mee on Sunday. Took in 'the Big Bus company' red line tour of Westminster, finishing off with a ride in the London Eye, it was an interesting day out and a welcome break from the laptop. I think Mee is starting to get upset with the amount of time I am spending in front of the screen. I'll need to start sticking to some kind of 'work hours' and put off all non-essential stuff somehow for a while, otherwise it's not fair on her. Only another four weeks in the UK, then we'll be back in Thailand, so she won't be so lonely then.

Oh, and one more thing of note. I see that the GPE project (GNOME on iPAQ) are looking to form closer links with the GNOME community. I really need to get my ARM-compiler environment cranked up a level, so I can fix some bugs and produce updated ipkgs for my iPAQ. I'd really like to look at 'bigger' iPAQ projects, such as porting gtranslator (and other 'normal' GNOME apps, such as gedit and gnumeric) to iPAQ. My GPE iPAQ is great, but still has a long way to go wrt integration with the GNOME desktop (and PIM software etc). I hope the GPE guys can integrate better into the GNOME project, and attract more developers to the cause.

OK, so I landed some work and haven't done much else for a week or so. However, Bruno Haible got back to me on the gettext stuff I'd been doing, and has offered to expose the parser and write by extending the interface in 'gettext-po.h' according to gtranslator's requirements. Fantastic!

gettext/gtranslator progress:

Apply this patch to gettext from CVS. Build and install. Check out the 'gettext-hack' branch of gtranslator from GNOME CVS. It's basic, but it works. Another day, I'll build a dialog to display the errors, and polish it up a bit more. Enough for today.

I also moved the archive over to the gnome.org servers, as sf.net mailman is lame.

Today, I did some more work on my gettext patch. I added a 'char **errptr' argument to the read_po_file function, and hacked it to return the error message to the calling application, rather than terminate the process (ala exit), and let the calling application report the message and choose how to proceed. Hopefully, the gettext developers will catch my drift and we can make the gettext library useful for any kind of application that needs a library to parse and/or write po files. I CCed a copy to the gtranslator-devel list, but it hasn't hit their archive yet. I'm going to try to move the gtranslator-devel list from sf.net to gnome.org.

I also followed up all the applications for volunteer GNOME sysadmins. Hopefully, with a few more hands on deck we can fix up all the broken services (e.g. bonsai/lxr, private list archives, request tracker etc), put some cool new ones in too (e.g. NAGIOS), and kick the GNOME sysadmin todo list into oblivion.

Toby is taking Kylie, Mee and I to London sightseeing tomorrow, which should be nice. Mee has never been to London before, and I haven't been for a long time.

Spent the last few days tinkering with character set problems and the new PHP5 DOM API. I've also found that cross-compiling programs on my laptop to run on my iPAQ isn't as hard as I thought, so for my next trick, I'll try compiling the 2.6 kernel tree for it. Nice to have the sound working on the iPAQ again. I now carry around about an hours worth of MP3s/Oggs, loads of pictures, reading material and all my documents, all on a 256Mb MMC chip in my iPAQ :)

I also finished up a few bits on my 'Harmony' project, which is a kind of PHP framework intended to make developing and maintaining new web applications easier. I put up the PHP docs and a tarball, if anyone is interested/curious. Feedback welcome!

I finally got round to setting up amavisd on the GNOME mail server. Now, it RBLs open relays, rejects connections if the sender/recipient addresses are dodgy, lets amavisd spamassassin and clamscan it, and only then lets it through.

I did this because I was getting fed up of the rising current of crap getting past postfix and hitting mailman's moderator queue. The spamassassin measures within mailman just weren't cutting the mustard. Hopefully, things should improve from here.

I also submitted a small patch for 'xkbd' to fix broken line number counting and error reporting. I then hacked out a Thai xkbd file, for use on my iPAQ, and submitted that too.

I also set up a load of DNS-SD records in my own domain, but haven't found anything that uses it yet. I'll wait for the new DNS-SD patches in gnome-vfs to filter through to debian unstable, and then I might start noticing new things appearing in Nautilus's Network view. That'll be cool when it happens.

What else? Not much today. I went shopping this morning with my mum and Mee. I also spent a little time cleaning up my laptop home directory and syncing it all up with my home server home directory (so stuff gets backed up to tape).

I just spent a while digging through some old GnuCash records preparing my expenses report for 2003 (need to get my tax returns in order). I noticed GnuCash isn't working on my laptop (Debian unstable missing libart_lgpl.so it seems), so ran GnuCash from my home server (running FC2). GnuCash is great, but I hate that it's python, and I hate that it still hinges on GTK1.2. It's useful, but ugly.

Tomorrow, I will have to get my teeth into some (paying) PHP stuff. It's not too bad, but I'd so much prefer to be hacking C code (e.g. tidying up gettext for better gtranslator integration, or preparing a gnome-ssh-agent panel applet), but sadly, I'll have to go back up a few language levels and write boring web applications for boring websites. If I don't, my chances of going back to Thailand with any money will be very slim!

Had a great day today. Outdoors. Away from computers.

I rigged my hang-glider, and pre-flighted it. I haven't unpacked it for nearly a year, but everything was just fine. It was a peachy day, and we regularly saw red kites circling, and at one point we saw a gaggle of about 20 sailplanes heading away from the top of a few seperate thermals well above Oxford.

John flew the tug, and aerotowed the Class 5 boys up to about 2500ft a time. Richard managed an out and return to Headington, near Oxford, from our take-off right next to Wheatley (about 45 mins airtime). Brendon got taken up right into a convenient thermal and it wasn't long before he was out of sight, heading towards Didcot. Nick did a circuit, but I don't think he had so much luck with the thermals and only lasted about 30mins.

Dave went up next, but about 300ft he seperated from the tug. Both craft made it back to the field, and it turned out that a tiny piece of grass found it's way into the carb and got stuck in the jet. Basically, it wouldn't rev up above about 4000rpm, but it needs to develop at least 6000rpm to power itself and the wing behind without sinking out. John realised he had began to sink out, and that it wasn't revving out properly, so he had to 'flush' Dave. Dave found himself cut free at about 300ft, with the tow rope dangling down from his chest. Worried that the tow rope wound catch on a fence below and drag him in, he released it and started concentrating on using his remaining height to get back to take-off. He just about squeezed in over the hedge.

So, we've fixed the engine and are scouring the nearby fields for our 'mislaid' tow rope. Eventually, we find the rope and so I'm thinking about getting clipped in and having a go, when we get a call from Brendan. He's had a bad landing in a field near Chalgrove, and he's broken his arm. The gang mobilise, with Dave and Richard diving into a car, and Nick shooting off in the tug (easier to find a downed glider by air). Apparently, Nick managed to land right next to Brendan, but for some reason, said it wouldn't be possible to take off out of the field, and that they'd need to dismantle it, put it on a trailer and drive it back to the hangar. Flying over for today!

So, after all this drama, all I managed to do was rig my glider, pre-flight check it and confirm that it's still airworthy (actually in pretty good nick), before having to pack it all away again. However, I had a very enjoyable day (away from the computer for a change!), and I'm looking forward to trying again in a week or two.

Patching gettext to expose it's file parsing and writing functions. (http://www.golder.org/~rossg/tmp/gettext-0.14.1.exposed.patch) - Strangely, I seem to have achieved basic functionality by simply patching it to install a handful of it's header files into $includedir/gettext-0.0. It's a dirty hack, but it should prove the concept. - Potential problem: if while eusing gettext's parsing routines, it chances upon the 'error' function, exit() is called. Looks like gettext will need patching further to make the error handling in certain functions a bit more 'caller-friendly'. I expect it'll be a case of having everything report errors back to caller somehow, then hooking a error handler in further up the stack so that the caller does the 'exit'. Hopefully, this can be done without breaking API/ABI compat. It seems a bit odd that the gettext guys don't seem to have anticipated this use-case scenario.

Patching gtranslator to use gettext's innards for the reading/writing PO files. (http://www.golder.org/~rossg/tmp/gtranslator-gettext.patch - against gtranslator CVS) - Compiles OK using '#include <gettext-0.0/config.h>' (and a couple of other gettext innards) to hook into the newly exposed gettext API, and '-lgettextpo' lets it link successfully. I've now dropped various fields from GtrMsg, replacing it with a pointer to the 'message_ty' structure for each message. I've also re-wired everything to use this structure instead of the old GtrMsg fields, and it compiles. Still got some work to do on the parser (it currently segfaults), but it looks like I might finally get round to killing this 'plural forms' thing and a few other parser-related issues at the same time.

I take back what I said when I agreed with Ali that Nautilus is getting worse. I actually started using Nautilus a bit over the last few days, after finding the 'close parent windows' feature. I became curious to see just what I could do these days if I wasn't so handy with a terminal, and I was pleasantly surprised. Once I'd gotten used to things and set up a couple of bookmarks, I realised how easy some jobs are now. I managed to mount my camera flash card, copy it to my laptop, open the folder up in gthumb, put a copy on the family Samba server so my mum and dad could have a look on their machine. I also managed to browse to my brother's computer, see a load of his music and open it in Rhythmbox. There's probably a couple of people now thinking 'duh? so what', but last time I tried doing stuff like this with Nautilus, I had problems (I can't remember exactly what, except that I recall it wasn't trivially fixed). Still room for improvement, but it's impressive already.

Spent most of the day out on the bike, showing Mee some of the nicer parts of the countryside and finding shops that sell spare parts for remote control gliders, so I can get mine fixed up and go flying one day soon. The wind's looking good, and I need to take Mee out every day, or she'll be fed up of watching me work every waking hour of the day. At least her vegetable patch is coming along now.

It's been a rough few days. I went to see my accountant, and realised I'd slightly underestimated my tax bill for last year. That put my budget out by 2000 quid. However, I then found out that the UK to Thai exchange rate has improved, so the land I'm looking to buy will turn out to be about 1000 quid cheaper than I had planned. The main problem is that the abundance of work that I was told would be available on my return to UK has slowly degraded into stories of 'they haven't paid up for the last job yet' and 'we're waiting for our client to commit before we can start', which has meant that most of this month has been a non-earner (well, I only managed to invoice a couple of hundred quid). Still, I should start seeing some action next month.

So, I've mostly been playing. Playing with subversion, trying to get myself more familiar with setting up a private CA and signing SSL certificates for web and mail services etc, working on my Harmony library and using it to develop a more reliable and useful homepage, and a few other bits that may prove useful for some upcoming jobs.

I also did some tedious jobs that I've been putting off for a while, like going through my 'birthdays calender' in Evolution (1.5), and making sure I have a contact record for each person, with an up-to-date birthday field. As Evolution has a 'Contacts' view, the birthday calendar will become redundant (or can be generated from the contacts database). I also moved all the old (2000-2003) information out of my main calendar into 'archive' calendars to reduce the size of my main calendar (for when I can get gpe-multisync to sync stuff with my iPAQ). I know the GPE project needs some help in this area, but I really should get on top of my other responsibilities first (e.g. gtranslator and some of the GNOME sysadmin jobs I've started but not finished).

I also saw one of the new ZX6Rs out on the road the other day. Seeing that, plus discovering my real tax liability has made realise that, as much as I love my bike, I'll have to sell it before I go back to Thailand. Instead of wasting money trying to get it shipped over to Thailand, I might as well stick with the CBR400 I've already got there, and save up for a new ZX6R. Actually, just looking at their site, based on where I'll be living a quad might be a bit more practical :)
