The patient is healthy but dead

Three weeks ago I was scanning in all our old analog pictures from the APS cartridge. I've found a nice guy who rents out an APS capable scanner in .nl.

While I was scanning this in on Adele (my iMac) I thought: let's reconfigure Frost (the Debian build machine, backup server, iTunes server and fileserver), so I did a final backup to a FW external HD and inserted a Debian net-install CD. Which failed to install.

A bit confused I tried an older Debian release, which got slightly farther, but it still failed with a write error. So in the end I booted a recent Ubuntu installer, apt-getted the smart utilities and got a report on the disk. The disk claimed it was healthy. However it used 100% of its replacement sectors and gave read errors all over the place. Oh and a write error on sector several sectors.

Lessons learned:
  1. Ask for smart support in the Debian installer
  2. Install the smart daemon on the next server
So now I'm looking round for a nice Q6600 based server, using an intel motherboard with buildin graphics (maximum Linux compatibility) 4GB ram and 1TB of disk. This turns out to be a problem. None of the big vendors want to sell me a powerful, silent, computer with only Intel buildin graphics, they all insist on throwing in some nVidia or ATI incompatible POS :-(. And the smaller companies all want to sell me 'Gamer' PCs, with the same POS cards. So I have to find somebody who will build to spec but will still give me some warranty...

Not having Frost means that I am not able to do any Debian uploads :-(. Not that I'm not buzzy: I've got 3000 pictures to name, tag and date... (and in some case reimport because iPhoto things that they are raw pictures instead of the 48 bit tiff images that they are)

enter the permuted index

Wouter did you ever see the two indexes of the Common Lisp Hyperspec? There is a normal index and a "permuted" one, which almost always does exactly what you want.

to iceweasel or not?

At $employer I have to use meetingplace a lot, so it was rather irritating that it did not work.

After a bit of digging I hear that it works with firefox 2.0 and java 1.6. But only the original firefox, if you use iceweasel (or any renamed version I think) the 'browser test' works, but then it will tell you that you have no java installed. Clearly the application searches for firefox, does not find it and decides to give a bogus error message.

Now. Is this a iceweasel bug? I think not, but having browser detecting and adapting pages will always exist I fear so changing them all seems difficult. So let's call it a safety feature :-)

Finally online again

My new employer pays for an ADSL line for me. A second line, adding a ADSL connection on another copper pair I was told. Perfect I though, let's order it. Little did I know what problems I would get into.

Two days ago our ADSL went dead. No messages, no calls, no nothing. I call the provider (mobistar) who tell me we cancelled the contract and then hang up on me! The day after I contacted the company that does the ADSL stuff for $employer, asking them if this was their doing. Their reply: "search, search... no we have no documents on you, it must be something internal to $employer, we know nothing". Two hours later I get an email from them asking for dates for the installation of the ADSL modem. On the 21st at the earliest.

Coincidence, right? I send an "un-fuck this right now!" email shortly after. 24h later I still have no reply.

No looking forward to 2 weeks without internet we started searching. So after some hacking and a good idea from my wife it turns out skynet "just" re-enabled my account of 2 years ago, same userid, same password. As if I never left.

Not good...

gone is sarge

from my CL repositories I have at my p.d.o pages. I will now track etch (and will try to get the packages into backports.org too), sid and ubuntu's dapper and edgy. I expect to track feisty after it is released.

Hmm. No release party in Belgium planned yet...

modern times

A colleague at work got his 'final end of year bill' from his electricity supplier. In Belgium you pay every month an amount based on the guess of the supplier of your usage. Because , he claims, his new house is drying out, so requires less energy to heat up, he consumed about 20% less energy then last year so their estimate was too high. Good: he gets 400 € back. Bad: the amount he has to pay a month goes up.

So he phones them up and asked why. The reason: the program to adjust the guess based on the usage of last year cannot handle a negative amount (you payed too much) so the program thinks the last estimate was 400 € a month too low instead of too high, so it adjusts it upwards. Next year it will adjust it even more up :-).

Now I know that the ABS function in FORTRAN exists already since the late 1950's so I think the problem is not their programs, but that this is an easy way to get an interest-free loan out of people that don't watch their bill with a eye for details.

'The Trap'

Yesterday I went to bed too late because I was captivated by the last episode of The Trap: What Happened to Our Dream of Freedom, a series by Adam Curtis. Even since I saw Pandora's Box I've been an avid viewer of his work. The Trap talks about what freedom is, and this morning I realised that many things he talked about can be seen in the OSS world, and more specifically in Debian. I'm certain Biella can write something much better (and shorter) and I'm still thinking about it, but I wanted to write some stuff down.
One of the main ideas is the modern western culture has been formed to appeal for people thinking like a model in the 'prisoners dilemma': they only case to further themselves. This lead to the idea that life (not only the economy) should be like a free market, and that people should be 'free' to choose what they liked. Of course in practice the rich are 'free' to send their kids to better schools then the poor who are 'free' but constrained to send their kids to worse schools. The program called this negative freedom: there is constrained freedom. Think of it as Microsoft's vision of freedom, their 'freedom to innovate' (which they don't), your freedom to select which of the N licences of vista is good enough for you. This limited freedom is more stable then the positive freedom that is actual seeking true freedom, without constraints. This positive freedom was then developed by Satre, Fanon and Shariati into the idea that true freedom could only be gained by armed struggle, to gain freedom but also an identity that transcends the simple individual.
The whole idea of the two freedoms was described by Isaiah Berlin and he also had the idea that freedom can only be gained by limiting the power of the state over the individual, otherwise both concepts of freedom would become tyrannical because the powers that be would decide what freedom is, and then suppress anybody that does not agree with that idea. Examples are the communists in the USSR, but also how the Americans turned to torture, imprisonment without tribunal to 'liberate the Iraqi people'. Or older still the Reign of Terror during the French revolution.
All of this has some relevance to OSS and Debian in particular. Don't we search freedom from constraints (licences, absence of source)? Don't we want a revolution in the use of computers? Are we not using disruptive means to get it? The introduction of a samba file-server in a pure MS environment by a disgruntled admin who just wants stuff to work could be seen as being almost a terrorist method of working. Not that we want to terrorise the population, but make them aware that an alternative exists. And this to chance the system. Sometimes the whole mindset does seem to be a little too much confrontational, almost towards having a real conflict. Just think about the many references that some disaster should wipe out the Seattle area. Are we not at risk of becoming tyrannical in many ways? Ignoring any Debian discussions, there is the whole FreeBSD/OpenBSD split, people complaining that wikipedia is removing contents the consider valuable, projects refusing to create howto's and introductions to keep the newbies away etc. OOS does seem to have a tendency to become tyrannical in some aspects. Not that this is always bad, see the benevolent dictators handling the Linux kernel or python.
If I understand the idea's correctly it means that even if we want freedom, from the moment we start using the powers of the project to limit somebody we start the slide towards being oppressive and tyrannical. Somehow I fear that all this will lead to a lot of reading and thinking...
