I had SSLv3 disabled for HTTP for quite some time. In the light of recent event, it is now also disabled for IMAP and SMTP. If you run into any trouble, let us know or update your clients.
We recently started using the slide function of iPython notebooks. Basically it allows you to partition your notebook onto different slides, slide fragments and subslides. Those can be exported to reveal.js
There is already a great viewer for notebooks on http://nbviewer.ipython.org. To save some steps in exporting, converting and adding reveal.js, I took the idea and added a slide viewer. Anyone can use it to link to their slides on Github, Gist or any other place. We even support Basic Auth. Check it out at:
Ansible is a great automation solution. I mainly use it to provision servers and launch Docker instances on them. Sometimes I need container attributes, like PID or Port to configure Nginx or monitoring tools.
While the Ansible documentation gives you some hints, I didn’t find it 100% obvious on how to solve this. Basically all your newly-created containers will end up in a list called docker_containers. It has the same structure as docker inspect.
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
