Fri programvara i skolan
Submitted by jonas on 16 July, 2007 - 14:00
Johan Schiff skriver på alt.tech om allsidigheten i utbildningen och vad det innebär att eleverna bekantar sig med proprietära programvaror:
Jag tycker att skrivningen om allsidighet i utbildningen borde vara mer förpliktigande. Skolorna lär inte eleverna datorkunskap eller ordbehandling; de gör dem beroende av Microsoft Windows och Microsoft Office - ett beroende som eleverna har med sig ut i arbetslivet.Jag känner igen det här från min tid på högskolan (i gymnasiet använde vi ganska sällan datorer): den traditionella utbildningen är på väg ut, och in tågar en ny utbildningsvåg där företagens intresse av utbildad personal på specifika programvaror står högt i kurs. När jag började på högskolan så fick jag alltid förklarat för mig att på högskolor och universitet lärde man sig de bakomliggande teorierna och allmängiltiga kunskaperna. En läkare skulle inte lära sig använda maskin X från tillverka Y, utan hur människan fungerade, så att de självständigt kan tillämpa dessa kunskaper och välja rätt verktyg efter jobbet i hand. En programmerare lärde sig utveckling, algoritmer, metoder, inte Borland Pascal eller Microsoft Visual C. Det här är kunskaper som följer med en person genom livet. Med åren har det här kommit att suddats ut, och företagen blir nu allt mer inblandade i utbildningen, under förespeglingen att högskolor och universitet vill utbilda elever som är eftertraktade på arbetsmarknaden. Något som jag tyvärr tror leder till en urvattning av de djupare kunskaper som universitet och högskolor brukade bjuda på. Man får en utbildning som inte är något värd fem-tio år senare i livet, när produkten man blivit utbildad på inte längre finns att få tag i. Ett enkelt exempel på detta är Ciscos utbildningar som drivs i mångt och mycket av bhögskolesverige. Högskolor och universitet betalar oftast dyra pengar för utbildning för sina lärare, utrustning till sina labb och för rätten att kalla sig en Cisco-akademi. Och när allt väl kommer omkring, så innebär det att nätverkstekniker som examineras direkt från start är stämplade med Cisco-tekniker i pannan. Som alt.tech påpekar så leder det här till ett beroende, inte bara på IT-området, och inte bara på högskola och universitetsnivå utan generellt över hela utbildningsområdet. Ett beroende som eleverna tar med sig ut i arbetslivet. Samhället borde starkt motverka den här dragningen och ta fram tydliga riktlinjer som syftar till att ge elever den allsidiga utbildningen som de har nytta av för resten av livet.

Working with sawdust
Submitted by jonas on 6 July, 2007 - 14:20
Quite early on, I bought a somewhat larger vacuum-cleaner, which I've now abused repeatedly to suck sawdust from walls and, primarily, floors. The sawdust has been used previously as insulation (and not such a bad one at that) in just about every place where there has been insulation. I started out in the hallway, where I had seen from under it that the sawdust insulation in the floor had fallen out and had built a way for water to rise from the ground up to the floor. Closest towards the door between the kitchen and hallway, the floor in the hallway had started to sag considerably.
The floor in the hallway was the newer boards on top, then a layer of smaller pieces of wood to level out the floor, a new lever of older floor boards under that, the sawdust insulation, and then floor boards under that, to prevent the sawdust from falling to the ground.
In the next picture, you can see the sawdust insulation after I've stripped away the top layers of the floor. You can see the log that the floor rests on to the right, and how it has been damaged by the years. What's not visible on this, but became apparent when I took away the sawdust, was as I said before, that the floor boards under the sawdust had been damaged and parts of the floor was actually resting on the ground under it.
Next a picture of the floor under the sawdust, and then a picture of the foundation once I'd stripped all floorboards away.
You can see the wall to the kitchen resting on the stone walls of the cellar, and also the extensive damage to the logs, where the right side of the top one has been completely crushed. I will either repair these logs with fresh wood, or remove parts of them all together and frame the new floor in a modern style. Since the floor must support clinker tiles, it needs to be strong enough to not shift anything. In either way, therefor, the foundation needs to be strengthened.
The stairway rests entirely on these two logs. Fortunately, the parts of the logs that are supporting the starway seems to be in good quality and can remain as they are. However, insulating from the bottom will be almost impossible, so the small cupboard under the stairs will be equipped with a raised floor under which I will place new insulation.
I will also place a new log running between the two existing logs to further support the stairway for the future.

Kom igång med Thunderbird
Submitted by jonas on 5 July, 2007 - 16:20
Jag har arbetat lite med vad som är tänkt att bli en kom-igång guide till Thunderbird, i samma stil som den kom-igång guide som OOo Authors har för OpenOffice.org. Den första publika versionen av denna finns nu här:
Det finns en hel del som borde putsas till. Bland annat ska det nog verifieras att allt stämmer mot senaste versionen av Thunderbird. Det bör också korrekturläsas samt en del bilder bytas ut för att vara konsistent (bilderna är från min Debian, så på några ställen har det smugit in namnet IceDove istället, vilket nog kan vara förvirrande när dokumentet i övrigt pratar om Thunderbird överallt).

Fira ett fritt Europa
Submitted by jonas on 30 June, 2007 - 17:09
På fredag, den 6e juli, kommer det att vara två år sedan den historiska dagen då mjukvarupatent slutligen förkastades av parlamentet, efter år av arbete från alla sidor. Det här känns som ett ypperligt tillfälle att fira två års frihet från mjukvarupatent i Europa! Bege dig till siten Free July 6, 2005 och se planerna som börjar ta form. Det vore jättekul om några kunde ta sig an att anordna firande här i Sverige. Det behöver inte vara mer än att träffas för en öl efter jobbet, men visst borde vi kunna ordna något?

The floors
Submitted by jonas on 29 June, 2007 - 12:52
What was done pretty early was to strip away the plastic floors to see what was hidden underneath (with the suspicion that they hid wood floors under them). And lo and behold, there it was, at least in the kitchen and chamber. Of admittedly varying quality, but it will probably look quite good once it's been cleaned up and screened.
This is the kitchen floor:
You can note that the boards on the right side are newer and narrower than the ones on the left. Parts of them will disappear anyway under the new sink and cupboards that will be on that side and which will extend further into the room than the old ones. What remains of the boards might be replaced with broader boards from elsewhere in the house, or manufactured new in the same style as the old ones.
The chamber looks about the same way, as you can see, but has a nasty line in the middle due to the fact that they used much shorter boards here (which is inherently a lot cheaper, since longer boards require trees that have grown in a very straight line for a long time). The floor here will be screened, oiled, and a thin piece of wood can be used to hide the line.
In the other corner of the chamber, on the way to the living room, another surprise awaits, however:
It's a corner stone from the foundation, probably part of the chimney shaft that is to the left of it. It might have been this way from the beginning, but it's also possible that as the house has set in the ground, the floor has sunk beneath the chimney shaft (which is pretty stable) leading to this stone finding itself in the chamber room.
This will likely be left as it is for the moment, maybe with some furniture placed above it to hide it from plain view. However, I think it does add to the patina of the house!
The hallway has much newer flooring, and was laid in the 1960s, at the same time as the plastic mat was laid above it. As such, it has modern narrow boards in it, which I've stripped away completely (more on this later). It doesn't seem suitable to place hardwood floors in a hallway where you come in from the rain with your shoes dripping wet, etc. On the other hand, plastic or laminate floors doesn't seem consistent with the age of the house.
One idea I have for the hallway is to lay a clinker floor with larger tiles and floor heating under it (as there is not much room in the hallway for a radiator anyway). I imagine something similar, but with smaller, more modern tiles, for the bathroom and toilet as well, which would basically mean that the floors in the house would be either wood or clinker, in a mixture of old and modern.

The renovation starts now!
Submitted by jonas on 22 June, 2007 - 18:43
In the words of Ty Pennington: The renovation starts now!
Welcome to this series of blog entries (in the category "Renovation") where I'll try to detail the steps taken to renovate the main house on the family farm in Ismundsundet, Sweden (about 50km outside of ?-stersund, which is geographically in the center of Sweden, but in the parts which most people would consider to be the north of Sweden).
I hit my head against the wall for a long time, trying to decide whether to write this in Swedish or English. In the end I decided to do this in English, since I know this will be quite interesting also to friends outside of Sweden.
This is the house in question:
Apart from the main house, the farm consists of two joined summer houses owned by my grandfathers sister, and my mom and aunt. There's also some barns and a wood shed on the lot, which otherwise consists of farm land and forest. In total, the lot is 40 hectares (98 acres), whereof more than 3/4 is forest.
The main house itself was, as far as I've been able to gather, built in the 1800s. And as with most buildings on the farm, it's a genuine timbered building. When it entered the family in the early 1900s, it was extended towards the front which created a new room on the top floor, a small porch and a two square meter room which was turned into a bathroom in the 1940s.The top floor is essentially not insulated at all, although the timber in the walls (about 6 inch thick) provides some insulation to the building generally.
The bottom floor was insulated and new three glaze windows were installed in the 1970s. However, since then, no major renovation has taken place, and is now dearly needed to get the house into a state where it has a modern living standard.
To place this into context, here's a map of the lot itself (1:40), a picture of the fields, the lake it borders and some pictures from the farm in winter time.
Just to clarify one point though: while we still call it a farm, it hasn't been active as a farm in many years. However, there's room for some chicken and smaller animals, two horses and three cows. Though it's unlikely that the facilities would be up to todays standard.
Back then to the main house, of which I've made the following two sketches which gives a rough blueprint (it's not exactly to scale, but rather close) of the layout of the inside of the house. A translation is in order: Kök = Kitchen, Kammare = Chamber, Vardagsrum = Living room, Arbetsrum = Office room, Sovrum = Bedroom, Vindsrum = Attic room.
Ending this post, I'll some unsorted images of the inside as it looked before I started the renovation. I will explain each room in more detail as I get on with the renovation and make the plans for each room.
We start of with the hallway on the first floor:
And proceed into the kitchen:
And then the chamber behind the kitchen (which has been used in recent years as a small bedroom):
Parts of the living room, please note the stove and the wonderful ceiling. You also see a small part of the hardwood floor.
The upstairs "office room":
And the newly (1910s) added front attic room:
Upstairs hallway (if you look hard enough to the right, you see the door to the attic room above):
Upstairs bedroom:
Food cellar under the kitchen (with entrance from the outside):
And with that, I'll leave you for the day. In the next post, I'll show you more details of the floors and what was found when we tore the plastic carpets away from them.

Renovering som sommarsysselsättning: där borta!
Submitted by jonas on 22 June, 2007 - 16:44
En del av anledningen till att jag inte bloggat på sista tiden är att jag börjat renovera familjegården i Jämtland, vilket gör att jag ett tag framöver primärt kommer att blogga om annan sorts hårdvara än den vi normalt är vana vid! Det hela sker dels på engelska, och dels har det ingenting direkt med datorer att göra, så det hela kommer att postas i renoverings-kategorin i min blogg, som inte visas på Gnuheter. Välkommen!

Chaos Computer Club
Submitted by jonas on 6 June, 2007 - 18:01
I veckan har jag varit i Düsseldorf, där FSFE har ett av sina kontor. Veckan inleddes med ett Fellowship-möte på Philipps där vi avverkade en 10l-tunna Alt-Bier (vi skulle ha tagit en 15l, för vi fick komplettera från baren en hel del efteråt) och bland annat visade upp FSFEs nya t-shirts (ljusblå med Fellowship-tryck och texten "Use, Study, Share, Improve" som referens till de fyra friheterna. Finns att beställa online).
Igår blev det sedan en hackerkväll med nyckelsignering hos Chaos Computer Club Düsseldorf där jag blev bjuden på Club Mate och, högst besynnerligt, en annan koffein-dryck jag inte hört talas om tidigare: Hermann Kola, lokalt producerad i Hamm ett stenkast från Düsseldorf, med den högsta tillåtna koffeinhalten i Tyskland (enligt uppgift "by special demand" från CCC Düsseldorf).
Något jag skulle ha tagit bilder på är också deras skylt perfekt anpassad för vilken demonstration som helst. Texten på skylten lyder "Jag är emot!"

?"ntligen hemma
Submitted by jonas on 19 May, 2007 - 09:32
"I would like, if I may, to take you on a strange journey."Med den inledningen från Borås-bandet Beseechs platta Souls Highway från 2002 tänkte jag försöka summera den senaste veckan, som inleddes av ett förvånande lugn under måndagen när vi trodde att allt var förberett, något som ruckades dagen efter när vi fick veta från Folkets hus i Göteborg att vi inte alls kunde komma tidigare och sätta upp vår utrustning i Draken utan på sin höjd kunde vara där en timme tidigare: när vi i normala fallet hade tänkt öppna dörrarna för besökarna. Det hela förlöpte dock utan större problem och gruppen utanför Draken var ganska massiv när vi väl släppte in folk som nästan genast fyllde halva salongen. Totalt under kvällen räknade vi till ca 800 besökare som lyssnade på Richard Stallman ge ett tal om fri programvara och om hur filosofin bakom fri programvara kan applicera till andra verk. Ett speciellt tack till våra långväga gäster, några av vilka jag vet kommit ända från Luleå till Göteborg för att lyssna på Richard! Vi sålde helt slut på alla exemplar av Richards bok, Free Software/Free Society, som vi hade tryckt upp, och kön ringlade lång när han signerade böcker. Vi sålde även slut på de flesta t-shirts vi hade med oss, liksom pins och annat (nu återstår webborder för de som vill köpa något!). På torsdagen gav Richard en intervju med tre journalister, och vi får väl se vad som kommer av den intervjun. Efter det begav vi oss till Linköping där Richard höll ett tal om Copyright vs Community. På plats i Linköping och organiserade det hela var föreningen Digifri som jag första gången stötte på efter Henriks och min presentation av FSFE i Linköping för två år sedan. Sen kväll i Linköping, en biltur till Norrköping, och sedan upp igen på fredagsmorgonen för Miljöpartiets kongress i De Geer-hallen. FSFE deltog och hade ett utställningsbord i foajén samt deltog med Richard i ett möte med deras Informationspolitiska Nätverk. Med tre-fyra minuter till godo kunde Richard sedan gå på tåget mot Stockholm för vidare transport till Arlanda och sen flyg ner till Paris för en föreläsning där i eftermiddag. Kort sagt, ett par hektiska dagar för oss, men än mer så för Richard som nu har fem-sex föreläsningar kvar i Europa innan han åker tillbaka till USA om bara lite mer än en vecka.
