26 now a great source of free maps available from
27 <a href=
"http://www.frikart.no/garmin/index.html">Frikart
</a>. To
28 download a map, just click on the country you are interested in, and
29 download the map type you want. There are
8 different maps available,
30 using different colours and data selection. Pick one of Roadmap, Topo
31 Summer, Topo Winter, Roadmap II, Topo Summer II, Topo Winter II,
32 "Trails - overlay map" and "Cross country - overlay map" (see the web
33 page for descriptions).
</p>
35 <p>The maps are updated weekly, so if you find something wrong in the
36 map you can just edit the
37 <a href=

</a> map source
38 (anyone can contribute) and fetch a fixed map a week later. :)

53 <div class=
"body"><p>Here in Norway, electronic invoices are spreading, and the
54 <a href=
"http://www.anskaffelser.no/e-handel/faktura">solution promoted
55 by the Norwegian government
</a> require that invoices are sent through
56 one of the approved facilitators, and it is not possible to send
57 electronic invoices without an agreement with one of these
58 facilitators. This seem like a needless limitation to be able to
59 transfer invoice information between buyers and sellers. My preferred
60 solution would be to just transfer the invoice information directly
61 between seller and buyer, for example using SMTP, or some HTTP based
62 protocol like REST or SOAP. But this might also be overkill, as the
63 "electronic" information can be transferred using paper invoices too,
64 using a simple bar code. My bar code encoding of choice would be QR
65 codes, as this encoding can be read by any smart phone out there. The
66 content of the code could be anything, but I would go with
67 <a href=
"http://en.wikipedia.org/wiki/VCard">the vCard format
</a>, as
68 it too is supported by a lot of computer equipment these days.
</p>
70 <p>The vCard format support extentions, and the invoice specific
71 information can be included using such extentions. For example an
72 invoice from SLX Debian Labs (picked because we
73 <a href=
"http://www.linuxiskolen.no/slxdebianlabs/donations.html">ask
74 for donations to the Debian Edu project
</a> and thus have bank account
75 information publicly available) for NOK
1000.00 could have these extra
80 X-INVOICE-AMOUNT:NOK1000.00
81 X-INVOICE-KID:
123412341234
82 X-INVOICE-MSG:Donation to Debian Edu
83 X-BANK-ACCOUNT-NUMBER:
16040884339
84 X-BANK-IBAN-NUMBER:NO8516040884339
85 X-BANK-SWIFT-NUMBER:DNBANOKKXXX
88 <p>The X-BANK-ACCOUNT-NUMBER field was proposed in a stackoverflow
90 <a href=
"http://stackoverflow.com/questions/10045664/storing-bank-account-in-vcard-file">how
91 to put bank account information into a vCard
</a>. For payments in
92 Norway, either X-INVOICE-KID (payment ID) or X-INVOICE-MSG could be
93 used to pass on information to the seller when paying the invoice.

95 <p>The complete vCard could look like this:

114 <p>The resulting QR code created using
115 <a href=
"http://fukuchi.org/works/qrencode/">qrencode
</a> would look
116 like this, and should be readable (and thus checkable) by any smart
117 phone, or for example the
<a href=

121 <p><img src=

123 <p>The extension fields will most likely not show up in any normal
124 vCard reader, so those parts would have to go directly into a system
125 handling invoices. I am a bit unsure how vCards without name parts
126 are handled, but a simple test indicate that this work just fine.

246 <p>With kids in the house, one challenge is getting them to sleep
247 during the night and wake up when it is morning. I mean, when I
248 believe it is morning, and not two hours earlier. In our household we
249 have decided that
07:
00 is the turning point, but getting the kids to
250 sleep until
07:
00 is a small challenge every day. They have adapted
251 quite well, and rarely wake up at
05:
00 any more, but some times wake
252 up at times like
05:
50,
06:
15,
06:
30 or
06:
45, and it is hard to put
253 the awake one to bed again without disturbing and waking the rest.
254 And I understand perfectly well that they fail to sleep until
07:
00
255 some times, as there is no way for them to know if it is before or
256 after the magic moment without coming and asking us parents.
</p>
258 <p>But yesterday I came up with a method to solve this problem. It
259 involve home automation. A few years ago I bought a
260 <a href=
"http://www.telldus.se/products/tellstick">Tellstick
</a> and RF
261 switches at the local
<a href=
"http://www.clasohlson.com/">Clas
262 Ohlson
</a> shop, allowing me to control lights and other electrical
263 gadgets using my Linux server. When I moved from the old flat to a
264 small house, I put away all this equipment as most of the lighting in
265 the house was not using wall sockets and thus not easy to connect to
266 the gadgets I had. But recently I bought a
267 <a href=
"http://www.telldus.se/products/tellstick_net">Tellstick
268 Net
</a> to be able to read sensor input as well as control power
269 sockets. I want to control ovens in the basement to avoid the pipes
270 to freeze, and monitor the humidity to detect flooding. The default
271 setup for Tellstick Net is to be controlled by the vendor web service,
272 which to me is a security problem, but it is also possible to build
274 <a href=
"http://developer.telldus.com/blog/2012/03/02/help-us-develop-local-access-using-tellstick-net-build-your-own-firmware">firmware
275 with local access
</A> instead of being controlled by a Swedish
276 company, thanks to the release of the GPL licensed firmware source
277 code. I plan to get that running before I let it control anything
278 important. But while working on this, one idea to make it easier for
279 the kids came to me yesterday. We can set up a night light controlled
280 by the computer, and turn it automatically on at
07:
00. The kids can
281 then check the light in the morning to know if they are supposed to
282 get up or not. They joined me in setting everything up, and I
283 repeated the concept several times before bed times to make sure they
284 remembered to check the light before getting up in the morning.
</p>
286 <p>We tested it this morning, and all the kids stayed in bed until
287 after
07:
00, and every one of them commented on the fact that the
288 "morning light" was turned on and signalled that the morning had
289 arrived. So this look like a success, and I am excited to see how
290 this develops the next few days. :) I really hope this can allow us
291 all to sleep a bit longer in the morning.
</p>
293 <p>A nice advantage of this setup is that we can remote control when
294 to tell the kids to get up. We do not have to wait until
07:
00, and
295 can also delay it if we want to.

437 <div class=
"body"><p>Yesterday, I
438 <a href=
"http://people.skolelinux.org/pere/blog/First_prototype_ready_making_hardware_easier_to_use_in_Debian.html">asked
439 for testers
</a> for my prototype for making Debian better at handling
440 pluggable hardware devices, which I
441 <a href=
"http://people.skolelinux.org/pere/blog/Lets_make_hardware_dongles_easier_to_use_in_Debian.html">set
442 out to create
</a> earlier this month. Several valuable testers showed
443 up, and caused me to really want to to open up the development to more
444 people. But before I did this, I want to come up with a sensible name
445 for this project. Today I finally decided on a new name, and I have
446 renamed the project from hw-support-handler to this new name. In the
447 process, I moved the source to git and made it available as a
448 <a href=
"http://anonscm.debian.org/gitweb/?p=collab-maint/isenkram.git">collab-maint
</a>
449 repository in Debian. The new name? It is
<strong>Isenkram
</strong>.
450 To fetch and build the latest version of the source, use
</p>
453 git clone http://anonscm.debian.org/git/collab-maint/isenkram.git
454 cd isenkram && git-buildpackage -us -uc
457 <p>I have not yet adjusted all files to use the new name yet. If you
458 want to hack on the source or improve the package, please go ahead.
459 But please talk to me first on IRC or via email before you do major
460 changes, to make sure we do not step on each others toes. :)
</p>
462 <p>If you wonder what 'isenkram' is, it is a Norwegian word for iron
463 stuff, typically meaning tools, nails, screws, etc. Typical hardware
464 stuff, in other words. I've been told it is the Norwegian variant of
465 the German word eisenkram, for those that are familiar with that
468 <p><strong>Update
2013-
01-
26</strong>: Added -us -us to build
469 instructions, to avoid confusing people with an error from the signing
472 <p><strong>Update
2013-
01-
27</strong>: Switch to HTTP URL for the git
473 clone argument to avoid the need for authentication.

488 <div class=
"body"><p>Early this month I set out to try to
489 <a href=
"http://people.skolelinux.org/pere/blog/Lets_make_hardware_dongles_easier_to_use_in_Debian.html">improve
490 the Debian support for pluggable hardware devices
</a>. Now my
491 prototype is working, and it is ready for a larger audience. To test
493 <a href=
"http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/">source
494 from the Debian Edu subversion repository
</a>, build and install the
495 package. You might have to log out and in again activate the
496 autostart script.
</p>
498 <p>The design is simple:
</p>
502 <li>Add desktop entry in /usr/share/autostart/ causing a program
503 hw-support-handlerd to start when the user log in.
</li>
505 <li>This program listen for kernel events about new hardware (directly
506 from the kernel like udev does), not using HAL dbus events as I
509 <li>When new hardware is inserted, look up the hardware modalias in
510 the APT database, a database
511 <a href=
"http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/modaliases?view=markup">available
512 via HTTP
</a> and a database available as part of the package.
</li>
514 <li>If a package is mapped to the hardware in question, the package
515 isn't installed yet and this is the first time the hardware was
516 plugged in, show a desktop notification suggesting to install the
517 package or packages.
</li>
519 <li>If the user click on the 'install package now' button, ask
520 aptdaemon via the PackageKit API to install the requrired package.
</li>
522 <li>aptdaemon ask for root password or sudo password, and install the
523 package while showing progress information in a window.
</li>
527 <p>I still need to come up with a better name for the system. Here
528 are some screen shots showing the prototype in action. First the
529 notification, then the password request, and finally the request to
530 approve all the dependencies. Sorry for the Norwegian Bokmål GUI.

538 <p>The prototype still need to be improved with longer timeouts, but
539 is already useful. The database of hardware to package mappings also
540 need more work. It is currently compatible with the Ubuntu way of
541 storing such information in the package control file, but could be
542 changed to use other formats instead or in addition to the current
543 method. I've dropped the use of discover for this mapping, as the
544 modalias approach is more flexible and easier to use on Linux as long
545 as the Linux kernel expose its modalias strings directly.
</p>
547 <p><strong>Update
2013-
01-
21 16:
50</strong>: Due to popular demand,
548 here is the command required to check out and build the source: Use
550 svn://svn.debian.org/debian-edu/trunk/src/hw-support-handler/; cd
551 hw-support-handler; debuild
</tt>'. If you lack debuild, install the
552 devscripts package.
</p>
554 <p><strong>Update
2013-
01-
23 12:
00</strong>: The project is now
555 renamed to Isenkram and the source moved from the Debian Edu
556 subversion repository to a Debian collab-maint git repository. See

573 <div class=
"body"><p>This Christmas my trusty old laptop died. It died quietly and
574 suddenly in bed. With a quiet whimper, it went completely quiet and
575 black. The power button was no longer able to turn it on. It was a
576 IBM Thinkpad X41, and the best laptop I ever had. Better than both
577 Thinkpads X30, X31, X40, X60, X61 and X61S. Far better than the
578 Compaq I had before that. Now I need to find a replacement. To keep
579 going during Christmas, I moved the one year old SSD disk to my old
580 X40 where it fitted (only one I had left that could use it), but it is
581 not a durable solution.
583 <p>My laptop needs are fairly modest. This is my wishlist from when I
584 got a new one more than
10 years ago. It still holds true.:)
</p>
588 <li>Lightweight (around
1 kg) and small volume (preferably smaller
590 <li>Robust, it will be in my backpack every day.
</li>
591 <li>Three button mouse and a mouse pin instead of touch pad.
</li>
592 <li>Long battery life time. Preferable a week.
</li>
593 <li>Internal WIFI network card.
</li>
594 <li>Internal Twisted Pair network card.
</li>
595 <li>Some USB slots (
2-
3 is plenty)
</li>
596 <li>Good keyboard - similar to the Thinkpad.
</li>
597 <li>Video resolution at least
1024x768, with size around
12" (A4 paper

606 <p>You will notice that there are no RAM and CPU requirements in the
607 list. The reason is simply that the specifications on laptops the
608 last
10-
15 years have been sufficient for my needs, and I have to look
609 at other features to choose my laptop. But are there still made as
610 robust laptops as my X41? The Thinkpad X60/X61 proved to be less
611 robust, and Thinkpads seem to be heading in the wrong direction since
612 Lenovo took over. But I've been told that X220 and X1 Carbon might
615 <p>Perhaps I should rethink my needs, and look for a pad with an
616 external keyboard? I'll have to check the
617 <a href=
"http://www.linux-laptop.net/">Linux Laptops site
</a> for
618 well-supported laptops, or perhaps just buy one preinstalled from one
619 of the vendors listed on the
