After I built in a new mainboard into my PC by the end of 2014 I couldn’t use the combo drive for 3.5″ disks and memory cards any longer. Therefore I built in a pure card reader as a temporary solution. However this card reader only used USB 2 and was quite slow – there was no other model available at that time.
Now it’s official: Pebble shuts down and the remaining stuff will be sold to Fitbit as you can read in the blog post. Pebble Time 2 or any of the other announced products will not be available at all.
Very sad – since I just bought my first Pebble in the beginning of 2016 and was always very pleased so far. The battery still lasts more than a week and besides notifications about new SMS or e-mails I also really like apps like “Nav Me” – as long as it will be possible.
Recently I’ve noticed that greylisting didn’t work any longer on my server. The reason for this was, that the service “postgrey” did not start any longer.
A manual start using the command line was still possible but not starting it as daemon.
A quick fix for this is to modify the file
/etc/sbin/postgrey as following: change the shebang in the first line.
#!/usr/bin/perl -T -w
However this also makes the script less safe as well. The better solution is a modification of the script as described on https://github.com/yasuhirokimura/postgrey/commit/9673b54064691a5b9c295ffea340d8a1f9ee1cb8.
… or: “let’s go to the sauna today”.
A few days ago I got a low back pain. One advice from the physician was the regular application of heat. Even a visit to a thermal bath would be quite appropriate.
An institution of this kind, which is easily accessible by public transport, is the Thermen an der Heerstraße.
The safe confinement in Chernobyl is about to be finished and should last for the next 100 years:
I’ve been living in Berlin for half a year now – and nearly three months in the new flat. By now I can say that I arrived, even though there are still many unknown places in the city and many things to explore. I find my ways to the office and to friends without a map and I still enjoy it to be able to use my bicycle most of the time.
From now on I use TLS certificates by Let’s Encrypt for all my services (web, e-mail, XMPP etc.).
This is not a classic certification authority (CA) but an initiative which was originally founded by Mozilla, the EFF and the University of Michigan and is now provided by the Internet Security Research Group (ISRG). The goal of Let’s Encrypt is it to provide encryption everywhere by offering the required certificates for free. Since April 2016 Let’s Encrypt is not beta any longer but officially in operation.
To use Let’s Encrypt a client is required which renews the certificates via the “ACME” protocol on a regular basis as the certificates are only valid for three months. For this I use the shell script getssl with which you can automate the process very easy. This script will be executed with a cron job once a day to check the age of certificates and renew them. It will also tell the affected services to reload their configuration or restart the affected services if required.
In October 2016 I participated the Vintage Computing Festival Berlin (https://vcfb.de) for the first time – with my old Atari 1040STe which still works fine even after 20 years. This is especially impressive for the harddisc.
There I showed how I developed my alternative desktop “Thing” and I explained the programs which I used for that (PureC, Interface, Everest and others).
Recently WordPress 4.6 was released. Unfortunately there is a little error in the text editor: when you move down in content in the “text” view and then edit something it may happen that the view jumps back to the top.
