For a long time, I’ve been wanting to set up my own server at home to host some services (backup, media server, etc ..). I had bought a Raspberry Pi but did not take the time to set it up and it just took dust in a cupboard for many months.

Recently, I discovered the Yunohost distribution, which is supposed to make self-hosting easy. Well, it does!. In a few hours, I had the server set up with the first services running. Things are really easy to administrate, applications are already packaged and can be installed in a click! The full catalogue is available at

At the moment I have the following services running:

  Post-rock rediscovery

Once an avid listener of post-rock music - particularly while working - I grew tired of it a while ago and switched to listening mostly radios (such as Radio Paradise, SomaFM digitalis, or French public service radio FIP).

I rediscovered my post-rock music folder while cleaning out my hard-drive and listened my way through it while working - most tracks being without vocals, it’s pretty good for focussing. Here are some pretty good albums suggestions for you:


  Happy Solstice

My shadow at 13:00. Norra djurgården national park, Stockholm.

The night is long, the Sun is low, but tomorrow, things start changing.

Happy solstice!


  Back to work

The quite comfortable train for the commute between Stockholm and Uppsala, with my bike on the left.
The first day of work getting out of hand.

It’s back-to-work time. After two months of parental leave, I went back to work 2 weeks ago, the day Covid restrictions were entirely lifted here in Sweden. Since them, I got to get into a routine, two days taking the train and working in the office, the rest working from home.

It’s good to see the office now more lively with more colleagues, and we also got our first regular observing run with CRIRES at the VLT. I was the remote observer for the first night - the dome did not open because of clouds :-(. However, the subsequent two nights were rather good and data flowed in!

  The hop harvest

Picking up the hops.
Some cones were dried on a window screen (shown here), some in the oven
Dried and packed hops ready for the freezer

In the spring, I planted 4 old varieties of Swedish hops in my residence [1,2]. Last week I finally harvested the previous cones, dried them, and froze them to be used in brewing beer in the coming weeks and months. For a first year, the harvest in not bad: I got around 450 g of dried hops, which would be enough for 100-200 litres of beer.

One of the first analog film I ever shot, with my dad’s old Praktica Pentor 2, just resurfaced. It is from 9 years ago, in 2012. A cheap, and great time-machine. I was in Uppsala at the time, doing my first reseach internship, with the people I have now ended up working with!
