>If you, like me, want an updated a map for your Garmin GPS, there is
15 now a great source of free maps available from
16 <a href=
"http://www.frikart.no/garmin/index.html
">Frikart
</a
>. To
17 download a map, just click on the country you are interested in, and
18 download the map type you want. There are
8 different maps available,
19 using different colours and data selection. Pick one of Roadmap, Topo
20 Summer, Topo Winter, Roadmap II, Topo Summer II, Topo Winter II,
21 "Trails - overlay map
" and
"Cross country - overlay map
" (see the web
22 page for descriptions).
</p
>
24 <p
>The maps are updated weekly, so if you find something wrong in the
25 map you can just edit the
26 <a href=
"http://www.openstreetmap.org/
">OpenStreetmap
</a
> map source
27 (anyone can contribute) and fetch a fixed map a week later. :)

>Here in Norway, electronic invoices are spreading, and the
37 <a href=
"http://www.anskaffelser.no/e-handel/faktura
">solution promoted
38 by the Norwegian government
</a
> require that invoices are sent through
39 one of the approved facilitators, and it is not possible to send
40 electronic invoices without an agreement with one of these
41 facilitators. This seem like a needless limitation to be able to
42 transfer invoice information between buyers and sellers. My preferred
43 solution would be to just transfer the invoice information directly
44 between seller and buyer, for example using SMTP, or some HTTP based
45 protocol like REST or SOAP. But this might also be overkill, as the
46 "electronic
" information can be transferred using paper invoices too,
47 using a simple bar code. My bar code encoding of choice would be QR
48 codes, as this encoding can be read by any smart phone out there. The
49 content of the code could be anything, but I would go with
50 <a href=
"http://en.wikipedia.org/wiki/VCard
">the vCard format
</a
>, as
51 it too is supported by a lot of computer equipment these days.
</p
>
53 <p
>The vCard format support extentions, and the invoice specific
54 information can be included using such extentions. For example an
55 invoice from SLX Debian Labs (picked because we
56 <a href=
"http://www.linuxiskolen.no/slxdebianlabs/donations.html
">ask
57 for donations to the Debian Edu project
</a
> and thus have bank account
58 information publicly available) for NOK
1000.00 could have these extra

64 X-INVOICE-KID:

16040884339
67 X-BANK-IBAN-NUMBER:NO8516040884339
68 X-BANK-SWIFT-NUMBER:DNBANOKKXXX

71 <p

74 to put bank account information into a vCard

75 Norway, either X-INVOICE-KID (payment ID) or X-INVOICE-MSG could be
76 used to pass on information to the seller when paying the invoice.

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

386 for testers
</a

388 <a href=
"http://people.skolelinux.org/pere/blog/Lets_make_hardware_dongles_easier_to_use_in_Debian.html
">set
389 out to create
</a
> earlier this month. Several valuable testers showed
390 up, and caused me to really want to to open up the development to more
391 people. But before I did this, I want to come up with a sensible name
392 for this project. Today I finally decided on a new name, and I have
393 renamed the project from hw-support-handler to this new name. In the
394 process, I moved the source to git and made it available as a
395 <a href=
"http://anonscm.debian.org/gitweb/?p=collab-maint/isenkram.git
">collab-maint
</a
>
396 repository in Debian. The new name? It is
<strong
>Isenkram
</strong
>.
397 To fetch and build the latest version of the source, use
</p

400 git clone http://anonscm.debian.org/git/collab-maint/isenkram.git
401 cd isenkram
&& git-buildpackage -us -uc
404 <p
>I have not yet adjusted all files to use the new name yet. If you
405 want to hack on the source or improve the package, please go ahead.
406 But please talk to me first on IRC or via email before you do major
407 changes, to make sure we do not step on each others toes. :)
</p
>
409 <p
>If you wonder what
'isenkram
' is, it is a Norwegian word for iron
410 stuff, typically meaning tools, nails, screws, etc. Typical hardware
411 stuff, in other words. I
've been told it is the Norwegian variant of
412 the German word eisenkram, for those that are familiar with that

439 <p

</p
>
443 <li
>Add desktop entry in /usr/share/autostart/ causing a program
444 hw-support-handlerd to start when the user log in.
</li
>
446 <li
>This program listen for kernel events about new hardware (directly
447 from the kernel like udev does), not using HAL dbus events as I
448 initially did.
</li
>
450 <li
>When new hardware is inserted, look up the hardware modalias in
451 the APT database, a database
452 <a href=
"http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/modaliases?view=markup
">available
453 via HTTP
</a
> and a database available as part of the package.
</li
>
455 <li
>If a package is mapped to the hardware in question, the package
456 isn
't installed yet and this is the first time the hardware was
457 plugged in, show a desktop notification suggesting to install the
458 package or packages.
</li
>
460 <li
>If the user click on the
'install package now
' button, ask
461 aptdaemon via the PackageKit API to install the requrired package.

463 <li
>aptdaemon ask for root password or sudo password, and install the
464 package while showing progress information in a window.
</li

468 <p
>I still need to come up with a better name for the system. Here
469 are some screen shots showing the prototype in action. First the
470 notification, then the password request, and finally the request to
471 approve all the dependencies. Sorry for the Norwegian Bokmål GUI.

479 <p
>The prototype still need to be improved with longer timeouts, but
480 is already useful. The database of hardware to package mappings also
481 need more work. It is currently compatible with the Ubuntu way of
482 storing such information in the package control file, but could be
483 changed to use other formats instead or in addition to the current
484 method. I
've dropped the use of discover for this mapping, as the
485 modalias approach is more flexible and easier to use on Linux as long
486 as the Linux kernel expose its modalias strings directly.

>This Christmas my trusty old laptop died. It died quietly and
509 suddenly in bed. With a quiet whimper, it went completely quiet and
510 black. The power button was no longer able to turn it on. It was a
511 IBM Thinkpad X41, and the best laptop I ever had. Better than both
512 Thinkpads X30, X31, X40, X60, X61 and X61S. Far better than the
513 Compaq I had before that. Now I need to find a replacement. To keep
514 going during Christmas, I moved the one year old SSD disk to my old
515 X40 where it fitted (only one I had left that could use it), but it is
516 not a durable solution.

543 last
10-
15 years have been sufficient for my needs, and I have to look
544 at other features to choose my laptop. But are there still made as
545 robust laptops as my X41? The Thinkpad X60/X61 proved to be less
546 robust, and Thinkpads seem to be heading in the wrong direction since
547 Lenovo took over. But I
