the printtool process on my Mac OS X Lion MacBook goes wild – related to my "Samsung SCX-4623F" MFP

"Killing" the printtool process itself doesn't help, because it gets restarted and shows the same problem again: eating up CPU resources.

The device is an MFP, i.e. it's also a scanner, and what seems to help me here, is to "kill" the "Smart Panel" (AKA SPanel) process.

I couldn't find a recent driver update on Samsung's support pages.

ZEmacs : a bundle of lisp extensions (on Sourceforge)


a rather obtrusive Chrome / Chromium extension: YAGBE - Yet Another Google Bookmarks Extension

YAGBE - Yet Another Google Bookmarks Extension

It attempts to add ads on deliberate pages, that you view. Those pages are not at all related to YAGBE. If consider that rather appalling and not at all tolerable.

o'Reilly Media book: The Data Journalism Handbook

The Data Journalism Handbook:
This collaborative book coordinated by the European Journalism Centre and the Open Knowledge Foundation aims to answer questions like: Where can I find data? How can I request data?

AVM has a daylight saving time problem with their FRITZ!Box and FRITZ!Fon products

My FRITZ!Box 7390 synchronises properly with the NTP servers, but it does not take the DST ("daylight saving time", in German: "Sommerzeit") into account, that started last night over here in Germany (e.g.).

When I log in to my box, it shows the date (day and time) like this:
$ telnet
# date
Sun Mar 25 10:05:09 CET 2012
It should show this instead:
Sun Mar 25 11:05:09 CEST 2012
The time itself is alright, just the DST is not.

On the IP-Phone-Forum there are currently 2 threads dealing with the issue:
Another look inside the box:

# ls -l /etc/TZ
lrwxrwxrwx    1 root     root             7 Mar  2 16:01 /etc/TZ -> /var/TZ
# ls -l /var/TZ
lrwxrwxrwx    1 root     root            19 Mar 25 11:01 /var/TZ -> /etc/default.049/TZ
# ls -l /etc/default.049/TZ
-rwxrwxrwx    1 root     root            45 Mar  2 16:01 /etc/default.049/TZ
# cat /etc/default.049/TZ
The TZ file looks like it's writable, but it's on a read-only filesystem.

The constituents of "M3.5.0" mean this:
  • The "3" means the 3rd month of the year.
  • The "0" means the 0th day of the week, i.e. the Sunday.
  • The "5" means neither the 1st through 4th, but the last Sunday.
Looks like AVM's software has a problem with determining the right date for the last Sunday of March in 2012.
On my blog in German I am referring to an article in a German magazine, that shows how and where to change the timezone "manually". (Somebody on the IP-Phone-Forum quoted that article, and that's how I found it.) My fix for 2012: replace that "5" by "4"!

Update 2012-03-26: AVM look like they don't want to announce a fix for this problem within the next couple of days [Link].

Update 2012-03-28: AVM provide a "Labor" firmware update.

my FRITZ!Box 7390 stopped functioning last night, but now it works again.

  • I tried restarting it in the morning, but it did not wake up.
  • I re-animated my 7270, and phone-wise it worked fine, but not DSL-wise – all that took quite a while.
  • The guy at the Deutsche Telekom support hotline told me, the 7270 would not talk VDSL, and my access was configured to be VDSL. He is right.
  • I was almost on my way to borrow a splitter and a VDSL modem router at the next Deutsche Telekom shop.
  • I replaced the device's power supply with a switchable one, that I have on stock. Why didn't I try that in the first place? Well … – are you always instantly aware of all your available options?
  • 7390 started up fine again. That made me happy again, at least on the level of happiness before last night's disaster.
  • Contacted AVM regarding the broken power supply.
  • I purchased the 7390 in May 2010.
  • Will they tell me, the 7390's power supply is too old to be replaced by them for free? Not unlikely.
  • But they could be nice and take my engagement into account, that I showed, when the dradio underscore URLs broke the Internet radio modules in their phone and WIFI repeater products.
  • Update 2012-03-14: AVM sent me a free replacement for the broken power supply.
