Frikanalen og NUUG jobber for å få TED talks kringkastet på -Frikanalen, for å gi et mer -variert innhold på kanalen som i dag sendes på RiksTV, Lyse og -Uninett. Før innslagene kan sendes må det lages norske undertekster, -og dette her trengs det frivillige. Det er hundrevis av innslag, men -mine favoritter er -James Randi og -Michael -Specter. Hvis du har litt tid til overs, bli med på å oversette -TED-foredragene til norsk og få på plass undertekster. TED har -allerede opplegg på plass for å håndtere oversettelser og -undertekster. Registrer deg på -sidene til TED i -dag!

- -

NUUG holder også på å få alle opptakene fra NUUG-presentasjonene -publisert -på Frikanalen. Foredrag på engelsk må også her tekstes og -oversettes. Ta kontakt med video@nuug.no hvis du vil bidra med -teksting og oversetting. Arbeidet koordineres på epostlisten og på -IRC (#nuug-video på irc.oftc.org), og en wikiside -brukes som notatblokk for arbeidet. Mest lovende verktøy for dette -ser i dag ut til å være -Universal Subtitles, som -lar en bidra med teksting via en nettleser.

Jeg flikket litt på OpenStreetmap.org i går, og oppdaget ved en +tilfeldighet at det er en rekke noder som representerer +overvåkningskamera som ikke blir med på kartet med overvåkningskamera +i Norge som +jeg +laget for snart to år siden. Fra før tok jeg med noder merket med +man_made=surveillance, mens det er en rekke noder som kun er merket +med highway=speed_camera. Endret på koden som henter ut kameralisten +fra OSM, og vips er antall kamera økt til 165.

+ +Kartet +er fortsatt ikke komplett, så hvis du ser noen kamera som mangler, +legg inn ved å følge instruksene fra +prosjektsiden. +Hvis du vet om noen flere måter å merke overvåkningskamera i OSM, ta +kontakt slik at jeg kan få med også disse.

Bilkollektivet vil ha retten til å se hvor jeg kjører...

How to test if a laptop is working with Linux

Jeg er med i -Bilkollektivet her i Oslo, -og har inntil i dag vært fornøyd med opplegget. I dag kom det brev -fra bilkollektivet, der de forteller om nytt webopplegg og nye -rutiner, og at de har tenkt å angripe min rett til å ferdes anonymt -som bruker av Bilkollektivet. Det gjorde meg virkelig trist å -lese.

- -

Brevet datert 2010-09-16 forteller at Bilkollektivet har tenkt å gå -over til biler med "bilcomputer" og innebygget sporings-GPS som lar -administrasjonen i bilkollektivet se hvor bilene er til en hver tid, -noe som betyr at de også kan se hvor jeg kjører når jeg bruker -Bilkollektivet. -Retten -til å ferdes anonymt er som tidligere nevnt viktig for meg, og jeg -finner det uakseptabelt å måtte godta å bli radiomerket for å kunne -bruke bil. Har ikke satt meg inn i hva som er historien for denne -endringen, så jeg vet ikke om det er godkjent av -f.eks. andelseiermøtet. Ser at -nye -bilbruksregler med følgende klausul ble vedtatt av styret -2010-08-26:

- -

Andelseier er med dette gjort kjent med at bilene er -utstyrt med sporingsutstyr, som kan benyttes av Bilkollektivet til å -spore biler som brukes utenfor gyldig reservasjon.

- -

For meg er det prinsipielt uakseptabelt av Bilkollektivet å skaffe -seg muligheten til å se hvor jeg befinner meg, og det er underordnet -når informasjonen blir brukt og hvem som får tilgang til den. Får se -om jeg har energi til å forsøke å endre planene til Bilkollektivet -eller bare ser meg om etter alternativer.

The last few days I have spent at work here at the University of oslo testing if the new +batch of computers will work with Linux. Every year for the last few +years the university have organized shared bid of a few thousand +computers, and this year HP won the bid. Two different desktops and +five different laptops are on the list this year. We in the UNIX +group want to know which one of these computers work well with RHEL +and Ubuntu, the two Linux distributions we currently handle at the +university.

+ +

My test method is simple, and I share it here to get feedback and +perhaps inspire others to test hardware as well. To test, I PXE +install the OS version of choice, and log in as my normal user and run +a few applications and plug in selected pieces of hardware. When +something fail, I make a note about this in the test matrix and move +on. If I have some spare time I try to report the bug to the OS +vendor, but as I only have the machines for a short time, I rarely +have the time to do this for all the problems I find.

+ +

Anyway, to get to the point of this post. Here is the simple tests +I perform on a new model.

+ + + +

By now I suspect you are really curious what the test results are +for the HP machines I am testing. I'm not done yet, so I will report +the test results later. For now I can report that HP 8100 Elite work +fine, and hibernation fail with HP EliteBook 8440p on Ubuntu Lucid, +and audio fail on RHEL6. Ubuntu Maverik worked with 8440p. As you +can see, I have most machines left to test. One interesting +observation is that Ubuntu Lucid has almost twice the framerate than +RHEL6 with glxgears. No idea why.

Oppdatert kart over overvåkningskamera i Norge

Some thoughts on BitCoins
+
2010-12-11 15:10
-

For ca. et og et halvt år siden -startet -jeg på et kart over overvåkningskamera i Norge, i regi av -personvernforeningen. Det har -blitt oppdatert regelmessing, og jeg oppdaterte det nettopp. Fra den -spede start med 22 kamera registrert er det nå registrert 54 kamera. -Det er bare en brøkdel av de kamera som finnes i Norge, men det går -sakte men sikkert i riktig retning.

- -

Informasjonen registreres fortsatt direkte inn i -OpenStreetmap, og hentes -automatisk over i -spesialkartet -når jeg kjører et script for å filtrere ut overvåkningskamera fra -OSM-dumpen for Norge.

+

As I continue to explore +BitCoin, I've starting to wonder +what properties the system have, and how it will be affected by laws +and regulations here in Norway. Here are some random notes.

+ +

One interesting thing to note is that since the transactions are +verified using a peer to peer network, all details about a transaction +is known to everyone. This means that if a BitCoin address has been +published like I did with mine in my initial post about BitCoin, it is +possible for everyone to see how many BitCoins have been transfered to +that address. There is even a web service to look at the details for +all transactions. There I can see that my address +15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b +have received 16.06 Bitcoin, the +1LfdGnGuWkpSJgbQySxxCWhv8MHqvwst3 +address of Simon Phipps have received 181.97 BitCoin and the address +1MCwBbhNGp5hRm5rC1Aims2YFRe2SXPYKt +of EFF have received 2447.38 BitCoins so far. Thank you to each and +every one of you that donated bitcoins to support my activity. The +fact that anyone can see how much money was transfered to a given +address make it more obvious why the BitCoin community recommend to +generate and hand out a new address for each transaction. I'm told +there is no way to track which addresses belong to a given person or +organisation without the person or organisation revealing it +themselves, as Simon, EFF and I have done.

+ +

In Norway, and in most other countries, there are laws and +regulations limiting how much money one can transfer across the border +without declaring it. There are money laundering, tax and accounting +laws and regulations I would expect to apply to the use of BitCoin. +If the Skolelinux foundation +(SLX +Debian Labs) were to accept donations in BitCoin in addition to +normal bank transfers like EFF is doing, how should this be accounted? +Given that it is impossible to know if money can across the border or +not, should everything or nothing be declared? What exchange rate +should be used when calculating taxes? Would receivers have to pay +income tax if the foundation were to pay Skolelinux contributors in +BitCoin? I have no idea, but it would be interesting to know.

+ +

For a currency to be useful and successful, it must be trusted and +accepted by a lot of users. It must be possible to get easy access to +the currency (as a wage or using currency exchanges), and it must be +easy to spend it. At the moment BitCoin seem fairly easy to get +access to, but there are very few places to spend it. I am not really +a regular user of any of the vendor types currently accepting BitCoin, +so I wonder when my kind of shop would start accepting BitCoins. I +would like to buy electronics, travels and subway tickets, not herbs +and books. :) The currency is young, and this will improve over time +if it become popular, but I suspect regular banks will start to lobby +to get BitCoin declared illegal if it become popular. I'm sure they +will claim it is helping fund terrorism and money laundering (which +probably would be true, as is any currency in existence), but I +believe the problems should be solved elsewhere and not by blaming +currencies.

+ +

The process of creating new BitCoins is called mining, and it is +CPU intensive process that depend on a bit of luck as well (as one is +competing against all the other miners currently spending CPU cycles +to see which one get the next lump of cash). The "winner" get 50 +BitCoin when this happen. Yesterday I came across the obvious way to +join forces to increase ones changes of getting at least some coins, +by coordinating the work on mining BitCoins across several machines +and people, and sharing the result if one is lucky and get the 50 +BitCoins. Check out +BitCoin Pool +if this sounds interesting. I have not had time to try to set up a +machine to participate there yet, but have seen that running on ones +own for a few days have not yield any BitCoins througth mining +yet.

+ +

Update 2010-12-15: Found an interesting +criticism of bitcoin. Not quite sure how valid it is, but thought +it was interesting to read. The arguments presented seem to be +equally valid for gold, which was used as a currency for many years.

Debatten rundt sporveiselskapet i Oslos (Ruter AS) ønske om -å -radiomerke med RFID alle sine kunder og -registerere -hvor hver og en av oss beveger oss pågår, og en ting som har -kommet lite frem i debatten er at det faktisk er en menneskerett å -kunne ferdes anonymt internt i ens eget land.

- -

Fant en grei kilde for dette i et -skriv -fra Datatilsynet til Samferdselsdepartementet om tema:

- -

Retten til å ferdes anonymt kan utledes av -menneskerettskonvensjonen artikkel 8 og av EUs personverndirektiv. -Her heter det at enkeltpersoners grunnleggende rettigheter og frihet -må respekteres, særlig retten til privatlivets fred. I både -personverndirektivet og i den norske personopplysningsloven er -selvråderetten til hver enkelt et av grunnprinsippene, hovedsaklig -uttrykt ved at en må gi et frivillig, informert og uttrykkelig -samtykke til behandling av personopplysninger.

- -

For meg er det viktig at jeg kan ferdes anonymt, og det er litt av -bakgrunnen til at jeg handler med kontanter, ikke har mobiltelefon og -forventer å kunne reise med bil og kollektivtrafikk uten at det blir -registrert hvor jeg har vært. Ruter angriper min rett til å ferdes -uten radiopeiler med sin innføring av RFID-kort, og dokumenterer sitt -ønske om å registrere hvor kundene befant seg ved å ønske å gebyrlegge -oss som ikke registrerer oss hver gang vi beveger oss med -kollektivtrafikken i Oslo. Jeg synes det er hårreisende.

+

Via en +blogpost fra Simon Phipps i går, fant jeg en referanse til +en +artikkel i Washington Times som igjen refererer til en artikkel i +det fagfellevurderte tidsskriftet Journal of Transportation Security +med tittelen +"An +evaluation of airport x-ray backscatter units based on image +characteristics" som enkelt konstaterer at +pornoscannerne +som kler av reisende på flyplasser ikke er i stand til å avsløre det +produsenten og amerikanske myndigheter sier de skal avsløre. Kort +sagt, de bedrer ikke sikkerheten. Reisende må altså la ansatte på +flyplasser se dem +nakne eller la seg beføle i skrittet uten grunn. Jeg vil +fortsette å nekte å bruke disse pornoskannerne, unngå flyplasser der +de er tatt i bruk, og reise med andre transportmidler enn fly hvis jeg +kan.

Terms of use for video produced by a Canon IXUS 130 digital camera
-
2010-09-09 23:55
+
Now accepting bitcoins - anonymous and distributed p2p crypto-money
+
2010-12-10 08:20
-

A few days ago I had the mixed pleasure of bying a new digital -camera, a Canon IXUS 130. It was instructive and very disturbing to -be able to verify that also this camera producer have the nerve to -specify how I can or can not use the videos produced with the camera. -Even thought I was aware of the issue, the options with new cameras -are limited and I ended up bying the camera anyway. What is the -problem, you might ask? It is software patents, MPEG-4, H.264 and the -MPEG-LA that is the problem, and our right to record our experiences -without asking for permissions that is at risk. - -

On page 27 of the Danish instruction manual, this section is -written:

- -
-

This product is licensed under AT&T patents for the MPEG-4 standard -and may be used for encoding MPEG-4 compliant video and/or decoding -MPEG-4 compliant video that was encoded only (1) for a personal and -non-commercial purpose or (2) by a video provider licensed under the -AT&T patents to provide MPEG-4 compliant video.

- -

No license is granted or implied for any other use for MPEG-4 -standard.

-
- -

In short, the camera producer have chosen to use technology -(MPEG-4/H.264) that is only provided if I used it for personal and -non-commercial purposes, or ask for permission from the organisations -holding the knowledge monopoly (patent) for technology used.

- -

This issue has been brewing for a while, and I recommend you to -read -"Why -Our Civilization's Video Art and Culture is Threatened by the -MPEG-LA" by Eugenia Loli-Queru and -"H.264 Is Not -The Sort Of Free That Matters" by Simon Phipps to learn more about -the issue. The solution is to support the -free and -open standards for video, like Ogg -Theora, and avoid MPEG-4 and H.264 if you can.

+

With this weeks lawless +governmental +attacks on Wikileak and +free +speech, it has become obvious that PayPal, visa and mastercard can +not be trusted to handle money transactions. +A blog post from +Simon +Phipps on bitcoin reminded me about a project that a friend of +mine mentioned earlier. I decided to follow Simon's example, and get +involved with BitCoin. I got +some help from my friend to get it all running, and he even handed me +some bitcoins to get started. I even donated a few bitcoins to Simon +for helping me remember BitCoin.

+ +

So, what is bitcoins, you probably wonder? It is a digital +crypto-currency, decentralised and handled using peer-to-peer +networks. It allows anonymous transactions and prohibits central +control over the transactions, making it impossible for governments +and companies alike to block donations and other transactions. The +source is free software, and while the key dependency wxWidgets 2.9 +for the graphical user interface is missing in Debian, the command +line client builds just fine. Hopefully Jonas +will get the package into +Debian soon.

+ +

Bitcoins can be converted to other currencies, like USD and EUR. +There are companies accepting +bitcoins when selling services and goods, and there are even +currency "stock" markets where the exchange rate is decided. There +are not many users so far, but the concept seems promising. If you +want to get started and lack a friend with any bitcoins to spare, +you can even get +some for free (0.05 +bitcoin at the time of writing). Use +BitcoinWatch to keep an eye +on the current exchange rates.

+ +

As an experiment, I have decided to set up bitcoind on one of my +machines. If you want to support my activity, please send Bitcoin +donations to the address +15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b. Thank you!

Martin Bekkelund: En stille bønn om Datalagringsdirektivet
+
2010-12-09 21:25
-

Jeg ble riktig fascinert av -en -artikkel i Aftenposten om hvor hardt Navteq jobber for å oppdatere -kartene som brukes i navigasjons-GPSer, der det blant annet heter at -"på grunn av teknikken tar det alt fra tre til tolv måneder før -kartene er oppdatert". Når en kjenner hva slags oppdateringshastighet -som er tilgjengelig på -OpenStreetmap som -oppdateres på dugnad, blir det litt trist å se hva noe av det beste en -kan kjøpe for penger får til.

- -

Fra en endrer kartdataene i databasen til OpenStreetmap tar det -ca. 15 minutter før endringen er synlig på kartet som alle kan se på -web. Dernest overføres det daglig til en kartdump som lastes ned av -personen som lager Garmin-kart for Norge ca. en gang i uken. Med -OpenStreetmap.org og Frikart.no -kan en altså ha korreksjonene på plass i sin Garmin-GPS i løpet av en -uke. Det er også av tekniske årsaker at det tar så langt tid. -Jobbene som tegner kartene, henter ut kartdumpene og konverterer til -Garmin-format tar minutter og timer å gjennomføre, slik at de ikke -gjøres kontinuerlig men kun regelmessing.

+

Martin Bekkelund ved +friprog-senteret har skrevet +følgende +korte +oppsummering rundt datalagringsdirektivet, som jeg videreformidler +her.

+ +

Det pågår i disse dager en intens diskusjon om +innføring av Datalagringsdirektivet (DLD) i norsk rett. Kanskje +har du gjort deg opp en mening, kanskje er du usikker. I begge +tilfeller ber jeg deg lese videre.

+ +

Samtlige fagmiljøer, både i Norge og EU, har konkludert med at +DLD ikke bør +innføres på nåværende tidspunkt. Den tekniske kvaliteten på direktivet +er dårlig, det griper uforholdsmessig inn i personvernet, det har +store mangler og viktige spørsmål som hvem som skal ha tilgang og +hvordan data skal lagres er fortsatt uavklart.

+ + + +

Jeg liker å tro at jeg er en hyggelig fyr. Jeg har et rent +rulleblad, og med unntak av to fartsbøter har jeg aldri vært en byrde +for samfunnet. Det akter jeg å fortsette med. Det er mange som meg, +lovlydige, pliktoppfyllende borgere som aldri vil utgjøre en trussel +mot noe som helst. Vi synes derfor det er trist og sårende at all vår +atferd skal overvåkes døgnkontinuerlig.

+ +

Understøttet av faglige vurderinger kan du trygt si nei til +DLD.

+ +

Ta kontakt med meg +hvis du har spørsmål om DLD, uansett hva det måtte +gjelde.

+ +

Denne teksten er å anse som Public +Domain. Spre den videre til alle som kan ha nytte av +den!

+

+ +

Siste melding +fra Nettavisen er at regjeringen planlegger å fremme sitt forslag +til implementering av datalagringsdirektivet i morgen, i ly av +fredprisutdelingen for å få minst mulig pressedekning om saken. Vi +får snart se om det stemmer.

Some notes on Flash in Debian and Debian Edu

In the Debian -popularity-contest numbers, the adobe-flashplugin package the -second most popular used package that is missing in Debian. The sixth -most popular is flashplayer-mozilla. This is a clear indication that -working flash is important for Debian users. Around 10 percent of the -users submitting data to popcon.debian.org have this package -installed.

- -

In the report written by Lars Risan in August 2008 -(«Skolelinux -i bruk – Rapport for Hurum kommune, Universitetet i Agder og -stiftelsen SLX Debian Labs»), one of the most important problems -schools experienced with Debian -Edu/Skolelinux was the lack of working Flash. A lot of educational -web sites require Flash to work, and lacking working Flash support in -the web browser and the problems with installing it was perceived as a -good reason to stay with Windows.

- -

I once saw a funny and sad comment in a web forum, where Linux was -said to be the retarded cousin that did not really understand -everything you told him but could work fairly well. This was a -comment regarding the problems Linux have with proprietary formats and -non-standard web pages, and is sad because it exposes a fairly common -understanding of whose fault it is if web pages that only work in for -example Internet Explorer 6 fail to work on Firefox, and funny because -it explain very well how annoying it is for users when Linux -distributions do not work with the documents they receive or the web -pages they want to visit.

- -

This is part of the reason why I believe it is important for Debian -and Debian Edu to have a well working Flash implementation in the -distribution, to get at least popular sites as Youtube and Google -Video to working out of the box. For Squeeze, Debian have the chance -to include the latest version of Gnash that will make this happen, as -the new release 0.8.8 was published a few weeks ago and is resting in -unstable. The new version work with more sites that version 0.8.7. -The Gnash maintainers have asked for a freeze exception, but the -release team have not had time to reply to it yet. I hope they agree -with me that Flash is important for the Debian desktop users, and thus -accept the new package into Squeeze.

+

A few days ago, I was introduces to some students in the robot +student assosiation Robotica +Osloensis at the University of Oslo where I work, who planned to +get their own 3D printer. They wanted to learn from me based on my +work in the area. After having a short lunch meeting with them, I +offered them to borrow my reprap kit, as I never had time to complete +the build and this seem unlike to change any time soon. I look +forward to see how this goes. This monday their volunteer driver +picked up my kit and drove it to their lab, and tomorrow I am told the +last exam is over so they can start work on getting the 3D printer +operational.

+ +

The robotic group have already build several robots on their own, +and seem capable of getting the reprap operational. I really look +forward to being able to print all the cool 3D designs published on +Thingiverse. I even got +some 3D scans I got made during Dagen@IFI when one of the groups at +the computer science department at the university demonstrated their +very cool 3D scanner.

My first perl GUI application - controlling a Spykee robot
-
2010-09-01 21:00
+
Debian Edu development gathering and General Assembly for FRiSK
+
2010-11-29 18:40
-

This evening I made my first Perl GUI application. The last few -days I have worked on a Perl module for controlling my recently -aquired Spykee robots, and the module is now getting complete enought -that it is possible to use it to control the robot driving at least. -It was now time to figure out how to use it to create some GUI to -allow me to drive the robot around. I picked PerlQt as I have had -positive experiences with the Qt API before, and spent a few minutes -browsing the web for examples. Using Qt Designer seemed like a short -cut, so I ended up writing the perl GUI using Qt Designer and -compiling it into a perl program using the puic program from -libqt-perl. Nothing fancy yet, but it got buttons to connect and -drive around.

- -

The perl module I have written provide a object oriented API for -controlling the robot. Here is an small example on how to use it:

- -

-use Spykee;
-Spykee::discover(sub {$robot{$_[0]} = $_[1]});
-my $host = (keys %robot)[0];
-my $spykee = Spykee->new();
-$spykee->contact($host, "admin", "admin");
-$spykee->left();
-sleep 2;
-$spykee->right();
-sleep 2;
-$spykee->forward();
-sleep 2;
-$spykee->back();
-sleep 2;
-$spykee->stop();
-

- -

Thanks to the release of the source of the robot firmware, I could -peek into the implementation at the other end to figure out how to -implement the protocol used by the robot. I've implemented several of -the commands the robot understand, but is still missing the camera -support to make it possible to control the robot from remote. First I -want to implement support for uploading new firmware and configuring -the wireless network, to make it possible to bootstrap a Spykee robot -without the producers Windows and MacOSX software (I only have Linux, -so I had to ask a friend to come over to get the robot testing -going. :).

- -

Will release the source to the public soon, but need to figure out -where to make it available first. I will add a link to -the NUUG wiki for -those that want to check back later to find it.

+

On friday, the first Debian Edu / Skolelinux +development +gathering in a long time take place here in Oslo, Norway. I +really look forward to seeing all the good people working on the +Squeeze release. The gathering is open for everyone interested in +learning more about Debian Edu / Skolelinux.

+ +

On Saturday, the Norwegian member organization taking care of +organizing these development gatherings, Fri Programvare i Skolen, +will hold its +General Assembly +for 2010. Membership is open for all, and currently there are 388 +people registered as members. Last year 32 members cast their vote in +the memberdb based election system. I hope more people find time to +vote this year.

Forslag i stortinget om å stoppe elektronisk stemmegiving i Norge

Why isn't Debian Edu using VLC?
+
2010-11-27 11:30
-

Ble tipset i dag om at et forslag om å stoppe forsøkene med -elektronisk stemmegiving utenfor valglokaler er -til -behandling i Stortinget. -Forslaget -er fremmet av Erna Solberg, Michael Tetzschner og Trond Helleland.

- -

Håper det får flertall.

+

In the latest issue of Linux Journal, the readers choices were +presented, and the winner among the multimedia player were VLC. +Personally, I like VLC, and it is my player of choice when I first try +to play a video file or stream. Only if VLC fail will I drag out +gmplayer to see if it can do better. The reason is mostly the failure +model and trust. When VLC fail, it normally pop up a error message +reporting the problem. When mplayer fail, it normally segfault or +just hangs. The latter failure mode drain my trust in the program.

+ +

But even if VLC is my player of choice, we have choosen to use +mplayer in Debian +Edu/Skolelinux. The reason is simple. We need a good browser +plugin to play web videos seamlessly, and the VLC browser plugin is +not very good. For example, it lack in-line control buttons, so there +is no way for the user to pause the video. Also, when I +last +tested the browser plugins available in Debian, the VLC plugin +failed on several video pages where mplayer based plugins worked. If +the browser plugin for VLC was as good as the gecko-mediaplayer +package (which uses mplayer), we would switch.

+ +

While VLC is a good player, its user interface is slightly +annoying. The most annoying feature is its inconsistent use of +keyboard shortcuts. When the player is in full screen mode, its +shortcuts are different from when it is playing the video in a window. +For example, space only work as pause when in full screen mode. I +wish it had consisten shortcuts and that space also would work when in +window mode. Another nice shortcut in gmplayer is [enter] to restart +the current video. It is very nice when playing short videos from the +web and want to restart it when new people arrive to have a look at +what is going on.

Just got an email from Tobias Gruetzmacher as a followup on my -previous -post about sshfs. He reported another problem with sshfs. It -fail to handle hard links properly. A simple way to spot this is to -look at the . and .. entries in the directory tree. These should have -a link count >1, but on sshfs the count is 1. I just tested to see -what happen when trying to hardlink, and this fail as well:

- -
-% ln foo bar
-ln: creating hard link `bar' => `foo': Function not implemented
-%
-
- -

I have not yet found time to implement a test for this in my file -system test code, but believe having working hard links is useful to -avoid surprised unix programs. Not as useful as working file locking -and symlinks, which are required to get a working desktop, but useful -nevertheless. :)

The latest version of the file system test code is available via -git from -http://github.com/gebi/fs-test

Jeg registrerer med vond smak i munnen at Den Norske Dataforening +hedrer +overvåkning av barn med Rosingsprisen for kreativitet i år. Jeg +er glad jeg nå er meldt ut av DND.

+ +

Å elektronisk overvåke sine barn er ikke å gjøre dem en tjeneste, +men et overgrep mot individer i utvikling som bør læres opp til å ta +egne valg.

+ +

For å sitere Datatilsynets nye leder, Bjørn Erik Thon, i +et intervju +med Computerworld Norge:

+ +

+- For alle som har barn, meg selv inkludert, er førstetanken at det +hadde vært fint å vite hvor barnet sitt er til enhver tid. Men ungene +har ikke godt av det. De er små individer som skal søke rundt og finne +sine små gjemmesteder og utvide horisonten, uten at foreldrene ser dem +i kortene. Det kan være fristende, men jeg ville ikke gått inn i +dette. +

+ +

Det er skremmende å se at DND mener en tjeneste som legger opp til +slike overgrep bør hedres. Å flytte oppveksten for barn inn i en +virtuell +Panopticon er et +grovt overgrep og vil gjøre skade på barnenes utvikling, og foreldre +burde tenke seg godt om før de gir etter for sine instinkter her.

+ +

Blipper-tjenesten får meg til å tenke på bøkene til +John Twelve +Hawks, som forbilledlig beskriver hvordan et totalitært +overvåkningssamfunn bygges sakte men sikkert rundt oss, satt sammen av +gode intensjoner og manglende bevissthet om hvilke prinsipper et +liberalt demokrati er fundamentert på. Jeg har hatt stor glede av å +lese alle de tre bøkene.
