About two years back, I bought a Seagate Backup Plus Slim 2 TB external 2.5 inch harddrive. I love it! So much so, that I tried buying a second one a couple of months ago. From the get go, that second copy behaved weirdly, The disk was slow and seemed to operate in intermittent sprints only. I finally got out a benchmarking tool and the the tests bore out that something was wrong, when compared with my original (older) copy. The original one is displayed to the left, the new one to the right.
When talking with companies about the use of open source, sooner or later we end up discussing the problem of license compliance. This is perhaps the most prominent aspect of open source governance for companies getting started with using open source. It can be surprisingly difficult to coherently explain the cause and effect chains that create the potentially high costs of not properly governing your open source engagement!
So here then is my take at teasing it apart.
I’ve been participating in various workshops and working groups on open data now. It is hard scrabble, but things are moving. Today I participated in a workshop of the open data task force of Bitkom which I am a member of. The highlight of the day was the participation of Saskia Esken who explained some and handled questions and answers on the new open data for government law that is coming up in Germany.
In related news, the task force finished its open data manifest, a collection of quality attributes of what good open data are and what to ask of providers and the government. A small handbook is in work as well.
In PROD, my course on software product management, students can choose to develop a business plan for a software product. Not all of my students seem to take this as serious as I wished. Here is the opening sentence of the exec summary from one of the teams:
With a total loss of 388,987.50 Euros in the period of 2017 to 2019, we will increase profit by 2,123,121 Euros and the customer base by 1392% […] Break even will be reached by mid 2018.
Reminds me off the bubble days: “We will make 80 cents for one dollar spent and will be profitable in no time!”
A few days ago, I participated in a panel on entrepreneurship in the beautiful but small city of Göttingen, Germany. While a university town, it isn’t exactly the Silicon Valley either, much like my current home town of Erlangen.
Thus, on the panel, I ran into the usual German morals on what makes a good entrepreneur, respectively, how to treat one:
As a first step, I had installed remote controlled (Z-Wave) thermostats for my radiators. In addition, I installed Devolo’s Control Center and registered on its website for access to the control center. I had thought, from a prior email exchange with Devolo’s support, that it would not be necessary to use their web service. However, I was not able to identify (or find documentation) about a web server or some other management UI on the control center, so I decided to go through their website. I resent this, as I didn’t necessarily want them to have data on my home configuration, but it was the fastest way to a working set-up.
The first step was still a hardware installation step. I needed to plug-in the control center box and connect it to the Internet. My current solution below utilizes a Fritz! product, Ethernet over power-line. The Devolo Control Center comes with its own built-in Ethernet over power-line support and is supposed to be plug compatible with the Fritz solution, alas, this did not work out of the box. It is the one remaining problem to solve for me, later.
As my first (rather small) home automation project I decided to install remote controlled radiator thermostats. (This is also known as a central thermostat and comes with most modern apartments, but then my new Berlin apartment is rather old and charming. It has no central thermostat, making me run around the apartment every morning to manually adjust the seven radiators.)
I chose Devolo’s “Home Control” thermostats and control center. This is an affordable entry-level product into the space of home automation, though the total of seven thermostats and one (proprietary) control center set me back about EUR 600.
