Dell XPS 13 9360 – Trackpad Issue

Several days ago the trackpad stopped working. It started when I connected a Apple Magic Mouse for more convenient playing. When I disconnected the mouse, I realized that the trackpad stopped working. Thinking the laptop just swallowed up I restarted the system. And sure enough, the trackpad worked again… for some hours. After that I just stopped working again. Sometimes it repeaired it self to the point that I could use it, but no multi touch gestures (pinch, scroll etc) would work. I had a look in the Hardware-Manager of Windows and saw a yellow exclamation mark next to a I2C HID-Device. The error message states “A request for the HID descriptor failed”, what ever that means.

Unfortunatelly there is no solution known to me. In the Dell forum two threads (one, two) describe my problem yet nothing seem to solve their issue. I’ll see the Dell support for this :-/

Is this thing dead yet?

I did it, I finished my masters in Informatics. After five and a half years I finally don’t have to worry any more about exams and tasks for the university. A relieving feeling.


Looking back at the time in the university (University of Applied Sciences Berlin) I’m happy that I took the challenge of starting to study. As I don’t have the normally mandatory “Abitur” I was only able to study because auf my apprenticeship and work experience. This actually helped me a lot to put some of the content of the lessons into context. Also I think that my higher age (compared to my fellow students) helped me, to take the study more serious.
The curriculum of the University is in my opinion OK. In the bachelor one of the specialization I tried for one semester (facility management) was not useful at all but the updated curriculum already ditched this topic. What I recommend to add to the curriculum would be a tutoring about Version Control, Build Server and CI early in the study. If I remember correctly those topics never arose but were introduced to students by other students who worked in companies.
The Master curriculum was a bit more disappointingly. The master has a focus on research, which is reflected in 32 credit points out of 90 being research related (plus the master thesis which is also research related). This was somewhat cumbersome. I learned a lot in those topics but as it stands now I don’t want to do research (see next section).
Additionally to learning about a lot of different topics, I met fantastic people over the course of the study and am glad to know them. I had a great time learning different topics and I realized I like to learn and switch topics often. Sometimes I wished I had more time at a specific topics but the next topic also were interesting. So much to learn so little time.
I also started to work besides the study at a company (BIG Social Media GmbH) where I learned a lot about C#, .Net, Node, Docker, CI and Version Control. I could use a lot of the ideas for my study (as well as the money obviously), so I recommend working besides the study. Also if you are in Berlin and looking for a job doing Bots, Node and JavaScript as well as C#: Have a look at there openings.

What will be next?

I have no idea what will be next. Currently I’m on holiday, travelling the world or at least some parts of it. I’m thinking hard about what I will do after that. I’ll need money so I have to work. And this work will be something with informatics. But what it will be explicitly: I have no idea. Maybe working as a consultant or freelancer as this would enable me to have different projects often. Or starting my own business as I have plenty of ideas (some of them even are not completely useless!). Or I find the perfect company which fit to my needs.
At least for my own desire to learn I have gifted my self some ebooks from Manning (I had a 50% off coupon):
  • Richard Feldman – Elm in Action (MEAP v3)
  • Enrico Buonanno – Functional Programming in C# (MEAP v6)
  • Dustin Metzgar – .NET Core in Action (MEAP v2)
  • Benjamin Tan Wei Hao – The little Elixir & OTP Guidebook
  • Jim Bennet – Xamarin in Action (MEAP v3)
As one can see functional programming (Elm in Action, Functional programming in C# and The little Elixir & OTP Guidebook) are one topic of interest as well as .Net (Functional Programming in C#, .Net Core in Action and Xamarin in Action). After I finished these I will post a short review (at least about the MEAP Versions)

Barcelona, day three: parc de la ciutadella and La Barceloneta

Our third day in Barcelona started with Bauernfrühstück. We had some cooked potatoes left and added some eggs, bacon and onions for a delicious meal. After the breakfast we headed for the parc de la ciutadella saw the font de la cascada, an imposant monument with (you would never guess) some cascading wells.

“Gaudi was here”

The park is nice, mostly populated by joggers, school classes and mammoths.
The three buildings which were marked in our map were all unsatisfying. The Castell dels tres dragons (a museum) was closed and had a site fence surrounding the building because of falling debris. Also the hivernacle as well as the umbracle building were closed and a little bit untended.
The university building of the Universitat Pompeu Fabra on the other hand was very nice. I have to admit that I don’t know so many other old university buildings (the campus of my university was build ~ 10 years ago) but the UPF has a nice mix between modern and traditional, old buildings.
Tip (blatantly stolen from our guide): Go into the university main entrance and go into the library. Follow the instructions to the dipòsit de les aigües. It looks really nice.

We had a quiet good (and for Barcelona cheap) meal at the university canteen (noodles with tomato sauce).

After the lunch we went to the beach. Unfortunatly the weather got worse (wind, no sun, wind and around 12° Celsius) and I could not swim in the mediterian sea. I have to catch up on that later. We walked the beach promenade and saw some of the tourist spots (like this copper fish)

The rest of our tour we underwent in the district of Barceloneta, where we tried to find stuff mentioned in our guide. But after ~5 hours of walking we were tired and headed home. We then had a real nice Rioja from 2005 with our salad.

Barcelona, day two: Montjuic and El barri gothic

The second day of our holiday started relaxed: We slept till 11 AM and had a long breakfast with cereals and toast. Interestingly enough the milk you can buy here in the supermarket gets sold uncooled. This seemed a littel bit odd to me, because in Germany almost all milk is getting sold cooled. The only milk in Germany you can buy uncooled is UHT-milk. So I assume the milk is kinda prepared as well. Also interesting: We bought everything for German breakfast (bread, butter, cheese and wurst) but the wurst happened to be cooked ham (called “Mini York”). That alone wouldn’t be bad at all but the ham tasted literally like nothing…

Anyway, we started our sunny day IMG_20150317_135609 with a metro ride (9,95€ for 10 rides, very cheap in comparison to Berlin) to the Placa de Espana where we walked our way up to the Museo nacional d’ Art de Catalunya IMG_20150317_155635. We went to see the German pavilion designed by Mies van der Rohe IMG_20150317_145650.

We planned to use the cable car to district El Raval, which was marked in our map, but this cable car just didn’t exist. So we took the bus to the station universitat where we strolled through the districts. We saw some nice small alleys (and found some guardian gooses IMG_20150317_183347) and ate some “original” catalan food. I bet they took more money from us than it was worth, but that’s the way of the tourist 🙂

I do know that the images are all messed up. I have to look into that when I’m back

Barcelona, Day one

Today my fiancée and I flew to Barcelona, for our vacation.  It’s a bit early in the year for a hot Spain holiday, but the city is big enough to cover some bad-weather days.

We flew with germanwings from Berlin at 11 AM and had a pleasantly easy flight. My fiancée and I played Ticket to Ride on her iPad (two times, we had a tie). By the way, Ticket to Ride is a nice game you should absolutly try it once (Amazon Affiliate Link)

In Barcelona we took the Aerobus Barcelona to the plaça del catalunya and walked the last part to our AirBnB accommodation. Next to our apartment is a small café, in which we had  café con leché and a bocadillo, while we waited for out host.

The apartment is small but nice. From our balcony we can see the Sagrada Familia

If you squint the eyes realy hard and lean from the balcony, you can the it
and we have a Mercato on the opposite of the street. After we ran some errands we prepared a nice tortilla with guacamole. Yummy!
Because of the holidays, I gifted my self with a set of different brands of beer:

Four different beers to taste

So far I tested three of them and they were all very nice.
