Are you already hosting your own mail- or webserver and do you enjoy the flexibility, control and freedom self-hosting gives you? Besides the many advantages like better privacy and the power to customize it gives you personally, you can also offer your services to other people. Even tough there are a large number of budget hosting companies, many customers are willing to pay for better support or the comfort to have you around for questions. More
Despite some notions that SSDs or HFS drives don’t need defragmenting, I have often read and experienced myself that defragmenting your Mac every few years will clearly make it faster.
I had some trouble running iDefrag and would like to share a little trick I learnt. Basically it will refuse to run a full defrag, while your system drive is mounted. Restarting didn’t help. Here is what I did in the end:
I noticed an increasing number of phising emails from ‘Telekom’ and ‘DHL’ making it into user mailboxes. ClamAV anti-virus together with Sane Security Phising checks does a good job in stopping zero-day phising emails.
On a different account, DKIM Email signing seems to be preferred by Google these days. So time to add that too.
Let me know if you notice any problems with that.
After years of preparation, we are proud to present a usable product of a stochastic optimization library. The core Java libraries were programmed by Nils Löhndorf. I contributed the iPython interface and other ‘glue’. We are excited to find out which uses people will find for this technology.

I use SSH for pretty much anything from VPN, server administration, database connections or iPython work on remote machines. When working from weird places and with weird internet connections SSH become painfully slow. I already use Mosh, but that also relies on ordinary SSH to initiate the connection.
Last week we discussed Linux Debian’s apt-get update mechanism and how to fully automate essential updates. This week I’d like to demonstrate how to do the same thing for Python. I admit that keeping Python packages up-to-date is probably not half as essential as keeping internet-facing server infrastructure updated. Nonetheless I like to work with the latest versions of packages, as they might fix problems or add features. More
This week’s massive SSL-security vulnerability showed how important regular security updates for all of our software is. Because – let’s face it – today’s world is largely powered by software. Software that is written by humans, who make mistakes when writing it. The rule should be: retire it or update it. More
I’m back in Shanghai and faced with the pollution problem once again. Here a quick update on the last months. You can clearly see a reduction in pollution around Chinese New Year, when factories are shutting down. With warmer weather the readings also seem to be lower. I don’t know the reason, but anecdotal evidence gives the same effect for Beijing. An expert from Vienna University of Economics is currently analyzing the data and correlating it with weather observations. I’ll give an update, when some results emerge.
This morning I came across this post by Kelly Norton. He calculated the number of ‘pleasant’ days for each US zip-code area. California seems to win the race with more than 180 ‘pleasant’ days each year. A pleasant day is defined by the min- and max temperature not exceeding certain limits.
I’d like to officially name my current dev stack:
A.. for AngularJS. Drives the user frontend.
S.. for Supervisord. Takes care of processes.
P.. for Python. Quick way to implement almost any business logic.
E.. for Nginx. Fast web server for static files and to add SSL.
L.. for Linux.
