+ Magnetstripeinnhold i billetter fra Flytoget og Hurtigruten +
+
+ 2010-05-21 16:00 +
+ +
+ +

For en stund tilbake kjøpte jeg en magnetkortleser for å kunne +titte på hva som er skrevet inn på magnetstripene til ulike kort. Har +ikke hatt tid til å analysere mange kort så langt, men tenkte jeg +skulle dele innholdet på to kort med mine lesere.

+ +

For noen dager siden tok jeg flyet til Harstad og Hurtigruten til +Bergen. Flytoget fra Oslo S til flyplassen ga meg en billett med +magnetstripe. Påtrykket finner jeg følgende informasjon:

+ +
+Flytoget Airport Express Train
+
+Fra - Til        : Oslo Sentralstasjon
+Kategori         : Voksen
+Pris             : Nok 170,00
+Herav mva. 8,00% : NOK 12,59
+Betaling         : Kontant
+Til - Fra        : Oslo Lufthavn
+Utstedt:         : 08.05.10
+Gyldig Fra-Til   : 08.05.10-07.11.10
+Billetttype      : Enkeltbillett
+
+102-1015-100508-48382-01-08
+
+ +

På selve magnetstripen er innholdet +;E?+900120011=23250996541068112619257138248441708433322932704083389389062603279671261502492655?. +Aner ikke hva innholdet representerer, og det er lite overlapp mellom +det jeg ser trykket på billetten og det jeg ser av tegn i +magnetstripen. Håper det betyr at de bruker kryptografiske metoder +for å gjøre det vanskelig å forfalske billetter.

+ +

Den andre billetten er fra Hurtigruten, der jeg mistenker at +strekkoden på fronten er mer brukt enn magnetstripen (det var i hvert +fall den biten vi stakk inn i dørlåsen).

+ +

Påtrykket forsiden er følgende:

+ +
+Romnummer 727
+Hurtigruten
+Midnatsol
+Reinholdtsen
+Petter
+Bookingno: SAX69   0742193
+Harstad-Bergen
+Dep: 09.05.2010 Arr: 12.05.2010
+Lugar fra Risøyhamn
+Kost: FRO=4
+
+ +

På selve magnetstripen er innholdet +;1316010007421930=00000000000000000000?+E?. Heller ikke her +ser jeg mye korrespondanse mellom påtrykk og magnetstripe.

+ More flexible firmware handling in debian-installer +
+
+ 2010-05-22 21:30 +
+ +
+ +

After a long break from debian-installer development, I finally +found time today to return to the project. Having to spend less time +working dependency based boot in debian, as it is almost complete now, +definitely helped freeing some time.

+ +

A while back, I ran into a problem while working on Debian Edu. We +include some firmware packages on the Debian Edu CDs, those needed to +get disk and network controllers working. Without having these +firmware packages available during installation, it is impossible to +install Debian Edu on the given machine, and because our target group +are non-technical people, asking them to provide firmware packages on +an external medium is a support pain. Initially, I expected it to be +enough to include the firmware packages on the CD to get +debian-installer to find and use them. This proved to be wrong. +Next, I hoped it was enough to symlink the relevant firmware packages +to some useful location on the CD (tried /cdrom/ and +/cdrom/firmware/). This also proved to not work, and at this point I +found time to look at the debian-installer code to figure out what was +going to work.

+ +

The firmware loading code is in the hw-detect package, and a closer +look revealed that it would only look for firmware packages outside +the installation media, so the CD was never checked for firmware +packages. It would only check USB sticks, floppies and other +"external" media devices. Today I changed it to also look in the +/cdrom/firmware/ directory on the mounted CD or DVD, which should +solve the problem I ran into with Debian edu. I also changed it to +look in /firmware/, to make sure the installer also find firmware +provided in the initrd when booting the installer via PXE, to allow us +to provide the same feature in the PXE setup included in Debian +Edu.

+ +

To make sure firmware deb packages with a license questions are not +activated without asking if the license is accepted, I extended +hw-detect to look for preinst scripts in the firmware packages, and +run these before activating the firmware during installation. The +license question is asked using debconf in the preinst, so this should +solve the issue for the firmware packages I have looked at so far.

+ +

If you want to discuss the details of these features, please +contact us on debian-boot@lists.debian.org.

+ Parallellized boot seem to hold up well in Debian/testing +
+
+ 2010-05-27 23:55 +
+ +
+ +

A few days ago, parallel booting was enabled in Debian/testing. +The feature seem to hold up pretty well, but three fairly serious +issues are known and should be solved: + +

+ +

All in all not many surprising issues, and all of them seem +solvable before Squeeze is released. In addition to these there are +some packages with bugs in their dependencies and run level settings, +which I expect will be fixed in a reasonable time span.

+ +

If you report any problems with dependencies in init.d scripts to +the BTS, please usertag the report to get it to show up at +the +list of usertagged bugs related to this.

+ +

Update: Correct bug number to file-rc issue.
