# The Week in Review – 2026-32
![The Week in Review – 2026-32](https://www.marcusjaschen.de/blog/2026/2026-32/images/title_hu_34f80643008dd47d.webp)

*If you can't be bothered to water, just say it is “dry grassland”. Be Berlin.*


🚗 Two weeks ago, I wrote that I had lost the [vehicle registration certificate
for the old VW Touran](/en/blog/2026/2026-30/#fahrzeugschein) six weeks earlier and had a new one issued at the
vehicle registration office.

Guess what was in the letterbox last week.

Exactly.

Now I temporarily have two vehicle registration certificates for the same
vehicle.

I will take the old one to the office today – that was the promise I had to make
when the new vehicle registration certificate was handed over: If the old
document turns up, it must be surrendered.

***

🗺️ I took a day off on Friday and could have spent it on the bike. Somehow,
though, I got stuck on [**Bikerouter**](https://bikerouter.de) and worked on a few things
that had been on the list for a while.
{#tiles}

Mainly, I implemented a handful of bug fixes; there is also a new overlay: It is
now possible to display the grid for the Level 17 tiles of Tileflood,
GeoActivityPlayground, or Squadrats.

The Level 14 grid already existed, but I have now implemented that properly from
a technical perspective as well. In “[TIL: Billig-Tileserver für
VeloViewer-Kacheln](/blog/2021/tileserver-veloviewer-today-i-learned/)” 🇩🇪 (“TIL: Affordable tile server for
VeloViewer tiles”), I described how I had cobbled together the overlay at
the time using rewrite rules in nginx.

Now, the grid is simply drawn directly in Bikerouter:

    Bikerouter*


As there was still some time left on my day off, I immediately started working
on a few tickets for the next release. There will also be real new features
again!

***

🖥️ I also spent quite a bit of time on infrastructure-related things for
Bikerouter again over the weekend. This was mainly about reducing the likelihood
of outages.

Not that there are any major problems here, as the services run quite stably.
But taking precautions is always better than unnecessary stress should the worst
come to the worst.

🚵‍♂️ Yesterday, I finally got out on the bike and once again headed towards
Berlin. The goal was to close the Squadratinho cluster (Yardinho) between Mahlow
in the south and Berlin-Mariendorf in the north:

*The situation beforehand …*


![… and after the ride.](https://www.marcusjaschen.de/blog/2026/2026-32/images/tiles-after_hu_4e3178a45c907bc0.webp)

*… and after the ride.*


What was really great: As it was supposed to get very warm, I displayed the
drinking fountains of Berliner Wasserbetriebe in Bikerouter beforehand and put a
“Point of Interest” (POI) for them on the map in three places.

These were exported along with the downloaded route, so I could display them
directly on the Garmin Edge while I was out and about.

That meant I could not miss the fountains and was able to conveniently refill
the bottles three times. There was no need to stop at petrol stations or
cemeteries.

I think one of the next larger Bikerouter features will revolve around POIs:
Handling them urgently needs to be improved. I am currently collecting and
sorting a lot of ideas for that.

💉 I received the second of the three necessary TBE vaccinations on Thursday
(see also [The Week in Review 2026-27](/en/blog/2026/2026-27/)).

Interesting: There is a trainee working at the doctor's practice, and on that
day, the doctor showed him how she administers intramuscular injections.

Since I was the model used for the demonstration, I now know what a
[deltoid muscle](https://en.wikipedia.org/wiki/Deltoid_muscle) is and where the injection should ideally be
given in it. Usually, nobody explains things like that to you.

Of course, I then grabbed the big anatomy book and looked into the matter more
closely.

***

🔧 Yesterday, I adjusted the height of one of the three patio doors. It had
shifted down a little over time.

It was not much more than a scant millimetre, but the tolerances of modern doors
and windows are quite tight, and the door rubbed ever so slightly when closing.

With the special 4 mm hex key that the window and door installer had put into my
hand at the time of handover, I could easily reach the screw head. This would
not have been possible with a normal™ Allen key, as there is not enough space to
insert it.
