and one month until Gunde's expected to give birth to our first daughter.

So exciting times ahead.

Cloud Expo Europe

Debian will be exhibiting at next month's Cloud Expo Europe on the 2nd & 3rd of Feb.
(well I will be — if you fancy keeping me company please add yourself to this page)

If you fancy visiting the show, you can register for free before midnight on the 1st of February (after that it costs £15.00 GBP)

oh, and later the same week,

I'm going to FOSDEM, the Free and Open Source Software Developers' European Meeting

Talking to my MP about the Digital Economy Act

I had a constructive meeting with my Member of Parliament yesterday, in which he agreed to push this critique of the Digital Economy Act (the dire nonsense that Lord Mandelson forced through in the dying seconds of the previous UK parliamentary session, apparently at the behest of the copyright exploitation industry, who will presumably now owe him a few lucrative consultancies)

If you're wanting to do something similar, feel free to use the content, or use it for inspiration, or just use the one-page PDF version if that's helpful to you in explaining the worthlessness of this law.

Note, I know there are many other points that could be made, but I was restricting myself to one side of A4 (just) -- MPs cannot be expected to read more it seems.

Debian Tartan: Batch 2 ready for cutting

The cloth is woven, so the tailors are busy collecting measurements. If you've ordered a kilt or whatever, and have not yet sent in your dimensions & money you need to do that within about 24 hours if you're hoping to get something in time for DebConf.

We seem to have got about 20 yards more than we ordered (weaving's more of an art than a science) so if you've only just realised that you want a kilt, skirt, whatever, in glorious Debian Tartan, I suggest you get in touch promptly, as even if you don't want it in time for DebConf, I imagine the rest will get snapped up as soon as people see what they've been missing in New York.

I'm getting some Ties made -- they'll cost about £25.00 GBP each. If you fancy one, tell me, and add yourself to this table on the wiki. There's more background on that page.

The rise of the Clan MacDebian

I've asked the weavers to start doing their job today, so with luck the tailors will still have time to make kilts ready to wear for DebConf10.

If you've been wondering if you'd like some Debian Tartan, now's your chance. We've ordered a little over 20 yards more than we need, which will be enough to make about 3 extra kilts and a few ties (depending on exact details), so order early to avoid disappointment.

Of course, kilts are not the only thing one can make out of tartan. The tailors make other things, but there's nothing stopping you from buying some cloth by the yard and being inventive (it costs about £25.00 GBP per yard). We'll also be making ties, so if you're interested in one of those, please add yourself to the relevant table on the wiki, and I'll get in touch with prices etc.

Full details of this silliness are available on the wiki page -- send any questions to phil at hands dot com

Debian Tartan, in time for DebConf10

It looks like we have just enough interest for a second run of Debian Tartan. If we get it ordered in the next couple of weeks there will be time for kilts to be made in time be worn at DebConf10.

The only issue at present is that it would be rather cheaper if more people were involved. For short runs the cloth costs £ 26.00 GBP per yard, and one also needs to find £ 400.00 GBP for the loom setup. Once you get to an order of 80 yards, the weavers will swallow the setup cost, and only charge £ 24.00 GBP per yard.

In other words, if we're making only 46 yards (which seems like the current level) it's going to cost £ 10 GBP extra per yard, which is frustrating, as that then means that buying the remaining 36 yards to make it up to 80 yards will only cost another £ 365.00 GBP or a tenner a yard.

If I wanted to make a profit out of this, I suppose I could speculate on the spare cloth, and then knock it out for 150% profit, but I have no desire to make money from my fellow developers, so while I'm chivying, and talking to the weavers, I'm not going to be underwriting the order like I did last time.

So if you're even slightly tempted to join this cheerful clan then mail me now! Every extra kilt, skirt, tie, or other item ordered not only results in you owning a beautifully crafted item, but it also does your fellows good by making their orders cheaper too.

At an order of 60 yards, the prices cross over, at which point there is no point in not making the full 80 yards, which can then be sold to late-comers to recoup costs for the early-birds.

Go on -- you know you want one.

arduino for the java challenged

Having excitedly bought an Arduino from the nice folks at tuxbrain.com while they were at DebConf9, I was then a little deflated to discover (while attending the UKUUG's Arduino Workshop in August), that the IDE is written in Java. While I can see that the authors might perceive this as the easiest way to provide cross-platform pointy-clicky-ness, JREs have a half-life of about an hour on my systems.

Anyway, I fought with Java to show willing, until I'd determined that the IDE didn't seem to be happy running under xmonad (rendering menus so that they were unclickable) and gave up -- spending the rest of the tutorial proving to myself that I could compile and upload C code for the little beastie, but failing to compile Arduino sketches on the command line.

Ever since, I've been meaning to work out the required CLI incantations, and finally made time over the weekend. The incantations turn out to be rather simple, if not very obvious, so I thought the world could benefit from a package that encapsulates the required knowledge.

I've pared the source tree down to the c++ code and some examples and tweaked the Makefile so that it'll do it's work out of tree, referring to the files that the package installs for you, which allows you to apt-get install aurduino-core and then cut&paste a few lines from the contained README.Debian in order to get an LED blinking for the first time.

The resulting git repo is now on Alioth. The binary-indep package it produces I've called arduino-core -- hopefully I've left enough room for any fan of the Java IDE to shove that back into the upstream branch and add packages for the full IDE, and maybe throwing in another package for the GTK IDE that's out there.

I'm very mildly concerned by the fact that Arduino is a trademark of the Arduino Team, but that trademark is for the circuits, not the software, so this is probably irrelevant. If you think I should care enough to rename the package to freeduino, say, please get in touch.

Anyway, if you have an Arduino (or similar) please grab a copy and test it.

new toy ordered

I managed to resist for a while, but after thinking about it for a couple of weeks, I've cracked and ordered a Pandora, which is a tiny palm-top cum gaming console, with an OMAP3530 (ARM Cortex A8) running at 600MHz, a smidgen larger than a Nintendo DS.

I'm not really interested in the gaming side, but am thinking that now that DisplayLink seems to be somewhat supportable on Linux I'll be able to plug it into a decent monitor when I'm home, and that the 10 hour battery life and pocket size will be great when I'm not.

Hopefully it'll be built and shipped in time for Xmas.

hello from sunny cáceres

Just a quick note for those planning on walking from the railway station to Debconf/camp.

Ignore the bit here about turning into Calle de Muñoz Torrero -- the walk-in entrance is in Avenida de Pablo Naranjo Porras.

The instructions should probably read something like:

... turn left into the Avenida de Bondad, follow that straight for 200 metres (enjoying the view to the lakes on the left) until you reach Avenida de Pablo Naranjo Porras, which you should turn right into and follow for about 600m. The venue is on the left hand side of the road, through some iron gates. There is a sign with Residencia Muñoz Torrero standing inside the open gates -- go past the sign for about 50m and the reception will be on your left near a similar sign.

I'll check the fine detail of that and update the web-site to match (once we get less restricted Internet sorted out)

Having said that, Calle de Muñoz Torrero is apparently the best thing to say to a local taxi to get here. So if you ask for that you'll find yourself standing outside a large green gate, with a park on the other side of the road -- stay on the same pavement as the gate, and walk anti-clockwise around the block until you find the gates mentioned above,

Securing passphrase-less ssh, using ssh-agent, command=, sudo and rrsync

I just came across yet another example of someone assuming that it's OK to create a passphrase-less ssh key and grant it root access on a remote machine.

Prompted by that, I've written how to do passphraseless-ssh properly.

One trick that I mention is having a script like this:

  #!/usr/bin/ssh-agent /bin/sh
ssh -A remote-server ~/bin/kick-off-job

allowing the remote machine to access us, but only when we're talking to them.
