FOSDEM summary

Back from FOSDEM.  I didn’t blog whilst there ‘cos although I’m OK with carrying low-sensitivity passwords (such as my WordPress one) on a mobile device, I had neglected to copy it to the pocket-puter.   Also missing – this time deliberately – the key to decrypt the backup copy available from my webserver.  And finally, a reset seemed OTT for such a brief interruption to blogging.

So what did I get this year?  Socially, I put faces to the names of long-standing online colleagues jMCg and (much more briefly) sjorge, and renewed acquaintance with a few other folks.  Techie-wise, I went to several talks, some of which were discussions in which I participated actively.  Finally jMCg and I met and chatted to Alex and Martin, who I didn’t know previously, but who are developing a really exciting-looking Apache module.

A new theme for me this year was mobile platforms.  I think quite a lot of folks are making that jump around now, as the ‘puter and smaller devices converge.   As I already said, lots of folks this year have foregone the pleasures of a bigger screen and keyboard for the convenience of devices that can be handheld and that run the whole day without having to find a power source.  While there were many different devices in use, the N900 seemed to be possibly the #1 geek gadget ahead of Android: evidently I’m not the only one to see it as the pocket-puter!

An old theme was upstream-vs-downstream, as Gentoo man Petteri Räty gave a session on how to be a good upstream.  Actually he just spoke briefly to bootstrap a discussion (a format well-suited to the subject).   Much of what he said was familiar because where I’ve done the wrong thing in the past, packagers have contacted me to explain how I could improve things.  Speaking as an upstream source for him, I was able to put the complementary view, and add my conclusion that what really matters is good communication.  There was general agreement when I cited Debian vs OpenSSL as exemplifying the perils of failure to communicate.

Alas, I missed the keysigning.  Two reasons: one a clash (to see Andrew Tanenbaum speaking is history in action, and might be a once-in-a-lifetime), the other a muddle (I hadn’t realised I needed to print out the list of keys/attendees myself back home first).  Tanenbaum, who spoke compellingly of the virtues of microkernels, was indeed one of the highlights of the event.

FOSDEM: the tools for the job

FOSDEM is huge and busy.  There’s a bit of a walk from the hotel to the venue.  And it’s only a weekend.

Last year I got some use out of the laptop, but it was also sometimes a liability: for example, when standing up, or when power outlets were scarce.  This year I have the pocket-puter, with sufficient battery life to last the day, and usable while standing.

So I’ll make the latter my primary device.  Question is, can I bring myself to leave the laptop at home this morning, and force myself to use exclusively the new toy?

Oh, and if you’re going to FOSDEM, see you there :)

Pain

Heard an interesting program on back pain on the beeb[1], featuring some apparently-novel clinic whose mission is to help sufferers cope and alleviate their pain.  Most of what they were doing sounds very familiar from my own experience.  But what they didn’t say was how ignorance amongst non-sufferers can lead to decisions that make things cripplingly much worse than they need be.

I’m interested in this because I have a history of back pain going back to my teens, and the long daily journey on a ghastly school bus.  Maybe it’s because it came upon me so young that I’ve learned to manage it, so that nowadays I rarely suffer anything more than mild discomfort (though I am at risk when my posture is constrained, for example in a theatre seat, or anywhere my legroom is too badly blocked).

But dealing with back pain does have an impact on my lifestyle.  Most importantly, it’s a (maybe even the) major reason why I work from home, having suffered badly in office environments at various times in the past.  It also affects what I can wear (clothes and shoes cannot have tightness or pressure in certain places, and definitely no wristwatch), how and where I can sit or lie, etc.

On the plus side, some things I enjoy doing are positively helpful.  Cycling is great, probably because of the muscles that get exercised.  Carrying the right backpack helps, probably because it holds me to a good posture.  When I worked in an office and suffered serious pain, these were sometimes the only reliefs that kept me going, though at worst even cycling was difficult.

There is a critically important point that the program did not make.  We should have more public information, not just for sufferers themselves, but for people who hold power over them.  The worst possible thing in an office is a bad chair, but almost as bad are most office desks, and above all those marketed as computer desks/workstations.  That’s because they force the legs into unsuitable positions which cause rapid onset of serious pain.  Best is to sit not at a desk but at a table with ample legroom under.

An office manager who insists on furniture conforming to institutional norms can basically drive a back pain sufferer out of a job.  It’s happened to me, and I’m sure I’m not alone!

A lesser gripe is with those supermarkets whose trolleys have a coin-operated lock on the handle.  I can’t push a Morrisons trolley, because the lock forces the right hand into a totally unsuitable place and buggers up my posture.  Since Morrisons[2] is now my only local big shop, this is a real inconvenience.  I’ve tried complaining, but all to no avail: presumably there’s simply no appreciation that it might matter.

In other health news, my tennis elbow has mended to the point where it’s no longer a significant problem, just something I need to be aware of and avoid setting it off again.  But I’m still using a mouse left-handed!

[1] Tuesday, but I fell asleep before blogging it.

[2] When I moved here, it was a Safeways, and the trolleys were not encumbered with those infernal locks.

Cheating

Pub quiz this evening.  Would it be cheating if I were to take the pocket-’puter (aka ‘phone) and use it to google?

In my book yes, it would be cheating.  But there must surely be people who do it.  In any case, who cares, in the context of something so supremely unimportant as a pub quiz?

What about other, more meaningful events?  How many pocket-puters get taken into the exams our young folks are doing for real-life qualifications?  I have a distant recollection of the question of allowing pocket calculators being a hottish topic in my day; nowadays the calculator is one and the same device as the phone, camera, walkman, pocket-puter, etc.  How is an exam invigilator to tell what other functions a candidate’s calculator offers?

On the other hand, maybe that’s supremely unimportant too.  A candidate with the nouse to google is going to find school exams utterly trivial, too.  And once you’re at university level, the ability to use available resources – including google – is a core part of the skillset you’re supposed to be demonstrating.

If you can fake sincerity …

Our most accomplished Liar has been questioned by the Iraq inquiry today[1].  The meeja can still find a few people to defend him, but not many, and even some of his fellow war-criminals (such as Jack Straw) have now turned on him.  Having nothing to lose by it, he put on a show of defiance.

The chattering classes seem pretty sure that Iraq will be The Liar’s legacy.  I’m not at all so sure: Iraq will pass into history, and become just another Suez.  He’s done altogether more damaging things to us.  Let’s take four of them in ascending order of importance.

OK, the first is a bit of a cheat: it was probably historically inevitable.  So, first, and least important, he’s brought corruption to the heart of government.  We’ve had a slew of high-profile cases starting with Ecclestone, and … list left as an exercise for the reader.  This is ironic, given that “tory sleaze” was one of the things that lost the 1997 election for his predecessor.  But that sleaze was small-scale stuff typified by £1000 to a backbencher to ask a parliamentary question[2].  Not millions, not at the heart of government, no direct purchase of government policy (so far as we know).

Second, he’s dismantled historical freedoms including those parts of human rights that are actually worth something.  You don’t need me to tell you about detention without trial or shootings and kidnappings of the innocent (and subsequent behaviour that’s not consistent with an honest mistake).  That some (notably not all) in the police should ask for elements of a police state is fair enough; that the government should give them all they ask and far more is not.

I’ve put this second because … I’m not clear to what extent this is Blair himself, when his best friend was opening up a whole Gulag at Guantanamo.  Maybe one could make a case that it’s as serious as the next one, though a long way from his worst legacy.

Third, what he’s done with our constitution, having spent much of his early years in office playing with it like a small boy with his toys.  In particular, Scottish (and Welsh) parliaments that leave the Westlothian Question and the Barnett Formula as open wounds (and on the other side, North Sea revenues) plunge the countries that make up the UK into a relationship that can only go one way: increasing resentment and hostility.  Fixing it is going to be a real headache for a future government.

Fourth, head and shoulders above the sum total of Iraq and all the above, is his most terrible legacy: the awakening of religious tension as a mainstream phenomenon.  Before Blair, we would live and let live.  Most of us were rarely aware of anyone’s religion (except in Northern Ireland), and didn’t see religious symbols as a threat or a challenge.  For example, the headscarves worn by some malaysian and indonesian students were just a cultural thing: nothing to worry or get upset about for anyone.  If one were to observe anything more it’s that the wearers always seemed to be a lot more attractive than the stern, elderly Catholic nuns in similar headwear.  Now we have us-and-them: the basis for suspicion, fear and hatred.  We all know those scarves have religious significance, and they and other overt symbols have been turned into something divisive.

The worst legacy is what he’s done to our schools and public life: You can have any religion you like, so long as you renounce the Enlightenment.  By promoting religion (including fundamentalist nuts) in education, we’re fostering a generation of “us and them”, to regard each other with fear and suspicion.  Now that’s the kind of historic legacy that can be with us for centuries, as witness the fear and hatred of Catholics that had its roots in the Spanish Inquisition, and such events in this country as the Gunpowder Plot (the “9/11″ of its day) and still lives on in Northern Ireland.  Instead of bringing peace to Northern Ireland[3], his lasting legacy will be NI-style us-and-them nationwide.

[1] As with the previous inquiries, this is being conducted by government appointees.  This one is getting some better material for the press than before, because they know they won’t go away until they’ve been thrown a bone or two that people find credible.  We can only speculate on what isn’t being said.

[2] And the far better reason for Major to lose was the level of nastiness in his party, that first saw off Thatcher, then gave Major a hard time, and peaked under Hague before subsiding in defeat.

[3] He may have improved Northern Ireland itself, building on Major’s work, though the current outcome is to have crushed moderate politicians on both sides and given power to terrorists and other extremists.  I suspect that the relative peace there may be a consequence of “9/11″, and many of the IRA’s american backers suddenly losing their appetite for terrorism in the UK.  Along with lots of money paying them off.

Who is blocking what?

I have a problem with identifying myself.  Again.  And I’ve come to the conclusion that if we haven’t yet reached a point where it’s harder for me than for a competent fraudster to prove my identity, we can’t have far to go!

Specifically, I need to provide proof of identity by means of a bank statement.  Not an electronic one, which is all I get.  This is in order to open a new account elsewhere, that’ll pay relatively decent interest.

OK, ask at my local agency.  No, they can’t supply it, but suggest I call their call centre.

Try the call centre (and navigate through a voice-driven system that is long but at least works surprisingly well).  They can send an interim statement (on headed paper, so *hopefully* OK), but a full one will cost a tenner.  Probably worth it in the circumstances, but …

It’s the end of the month, so my regular statement should be due.  If I go online and amend my options to receive paper statements, it’s free.  Simple enough.

Except …

The system just hangs when I try to submit the request.  Dammit, now I recollect it doing the same thing repeatedly over about a week when I tried to view my full creditcard statement (which is mid-January).  Hmmm …

All this while I’m on the phone to the call centre.  They can’t change my options for me, and tell me to go back to my branch.  Grrr ….

Plan 3, get it up on the pocket-puter, and go down to the branch with that.  Try resubmitting a few times as I walk down the street.

And lo … suddenly it works, acknowledges my request!

What had changed?  I’d just walked out of range of my wifi, and submitted over the ‘phone network (and the different IP address didn’t log me out – so at least something was right)!  Presumably all that’s changed is that I was accessing them through a different route, and it suddenly works!

I have something slightly similar with some Yahoo sites, where access from my IP just hangs (this has not always been the case), but it works fine if I go through a proxy.  What gives?

Living with Maemo

OK, I’ve had the new pocket-puter a couple of weeks now, and apart from that keyboard I like it.  As predicted, I’ve come to terms with the touchscreen and find it easy to use (except for some web controls which can be hard to pick up: e.g. the volume control on the BBC iplayer).

Overall, I prefer the hardware on the old E71, with the obvious exceptions of the screen and camera where the N900 excels.  But the Maemo software is incomparably better.  Just to take one example, I want to connect to the ‘net using a wifi network where available but otherwise defaulting to the telephone network.  While Symbian requires a deal of faffing to do that, Maemo “just works”.

When I was contemplating the purchase, I asked on this blog what Maemo really is, and was assured that it’s a real Linux.  I can confirm that it is indeed that, and that I can install Linux packages through the Debian tools (apt-get et al).  I have yet to install gcc and a developer environment, but I don’t anticipate any difficulty with it.

Maemo is not stripped down to a toy: rather it takes a Debian base, and adds an alternative GUI, which is optimised for the small screen.  It’s intuitive and easy to use, and makes brilliant use of available screen space and the touchscreen.  Interactive applications toggle easily between fullscreen, fullscreen-with-toolbar, and thumbnail (minimised) with a consistent look-and-feel.  The web browser is a small-screen skin on gecko (firefox), and is not bad.  The mailer is positively nice, or will be when I figure out how to fix composition to get rid of pseudo-HTML: much better than some mainstream mailers I use, including thunderbird and to a lesser extent Mac mail.

One thing has me baffled: how do I bootstrap a password either for root or sudo?  After googling for a solution, I worked around it by installing a rootshell which gets me passwordless root powers (!), but that’s not the kind of hack to which I expect to have to resort.  /me shudders.

I’ve looked at Nokia’s OVI store, but I don’t see so much point to most of it when I have the whole repertoire of *X apps at my fingertips.  OK, having said that, I’m sure I’ll install some things: the radio player, for instance.  I installed a weather widget, but I don’t even recollect if that was from OVI or pre-loaded, and it’s only really a toy.  The only serious app I installed was the root shell, which seems to be a prerequisite for using apt!

One more slight niggle: on the E71, Nokia’s maps are nice, but Google’s are nicer.  On the N900 there’s no google maps: I can get them on the ‘net, but that loses the GPS functionality.  So it’s Nokia or nothing with the GPS.

But in a sense, all this is mere detail.  What I now have is connectivity from anywhere I can get the ‘phone network.  So I needn’t lose email, ssh, etc (and be fretting to get home) when I spend a day or two somewhere with no wifi available, whether it be in a technophobe house or up on the moors.  Yay!

Pocket-puter

This is a first post from the Nokia N900, using not my own wifi but O2’s mobile 3G (or whatever it’s called these days) network.

I have to say, I’m a bit disappointed.  I’m sure I’ll get used to the touchscreen, but altogether less inspired by this keyboard.  Having lived a year with the beautifully-engineered E71 and the world’s smallest (but nevertheless easy and pleasurable to use) QWERTY keyboard, I had some faith in Nokia’s designers.  It was evidently misplaced: this keyboard is poorly-designed and will always be a pain to use. Next up: try it with a full-size USB or bluetooth keyboard, but that doesn’t help when out in the hills, or on the bus.

I still expect to find uses for it.  It’s already better for Web than the E71 (bigger screen), and being Linux means I can presumably install things like decent mail and IRC apps.

[update] fix the typos that were inevitable on the N900 (but which magically don’t happen on the E71).

FOSDEM

Yes, I’m planning to be at FOSDEM next month.  Traveling by Eurostar Friday and Monday for a full weekend in Brussels.

I’ve booked the Renaissance Hotel, which is the same place I stayed last year.  I can recommend it to anyone who isn’t afraid of a bit of a walk: it’s a nice place, and quite a bit closer to the FOSDEM venue than a city-centre hotel.  And at winter weekend rates, the room price is vastly more reasonable than is usual in European conference cities!  But I don’t know if there’s a bus/tram route for non-walkers.

Anyone keen to meet up, drop me a line (if we’re not already talking about it).  Also, don’t forget to sign up for the PGP keysigning.

Still a mild winter!

Our news seems to be dominated by the “big freeze”.  Real snow, exceptionally low overnight temperatures (-21° somewhere in the Scottish highlands), and now little opportunity to thaw even by day.

Needless to say, we’re thoroughly mild by international standards.  Among places I’ve lived through a winter, not just boreal Sweden and continental Bavaria are routinely colder; even mediterranean central Italy gets it: I’ve slept under the stars in -20° there myself (and bought a winter-grade sleeping bag after a night of that)!

But here’s a telling point against our own history.  In the 1980s, the government introduced “cold weather payments” for pensioners when temperatures dropped below -2° continually for several days[1].  That was daytime maximum temperatures.

This year’s “big freeze” is still too mild to trigger those cold-weather payments!

A few days of freezing fog to keep the daytime sun out could bring us there.  But there’s no sign of that.  This is ideal weather for those with solar panels!

[1] I think the threshold was five days, but I can’t remember for sure.
