since it’s school vacation in Berlin I took time off as well and we moved to our house in the #uckermark.
There was a lot of woodworking waiting for me. Last spring there was a big storm taking down many trees in the surrounding forests. So we’ve got a few cubic meters of wood for a very good price. But it has to be cut down and split to dry properly.
Spend all Monday cutting down the big pile of logs with my trusty chainsaw.
On Tuesday we got a hydraulic splitter from a friend. But somehow we managed to break it and blew one of the hydraulic hoses.
Turns out it’s not entirely trivial to replace such a hose. Apparently the fittings are not really standardised and you can’t just by them in a normal DIY shop. You have to find a specialised shop to custom make the hose with the proper fittings.
The first problem but was to get the hose off the splitter. Of course I first had to buy a proper wrench that size. From a agriculture hardware shop in the nearest town I’ve got the address of the closest hydraulic service company.
Living in the countryside this means a lot of driving and time. Had to go to the nearest city for the proper wrench and then to a smaller village about 50km from our place to have the new hose made. All in all about 4hrs and 150km later the machine was working again.
Wednesday to Saturday we spent parts of the day with splitting and stacking that wood.
This will last for a few years …
On Sunday we attended one of two sessions of “Worte, die die Welt bewegen“ – a choir concert in the “Maria Magdalenen Kirche” in Templin. This was a joint venture of the local choir, the “Filmorchester Babelsberg”, “Preußisches Kammerorchester” and several solo artists.
Quite an impressive concert
Of course we started the new week (counting Sunday as the start of the new week in this context) with swimming in the lake.
Decided to move the storage backend of my Object Storage at home from the local HDD to the NAS. That way I avoid the regular backup over the network. The linux machine is connected via wired network to the NAS system and I hope the NFSv4 connection is stable enough. At least the NAS with its RAID and Backup gives me a little more peace of mind that that single aging HDD.
Set up another Mastodon Instance for a friend on my machine.
in time for easter I printed another batch of egg cups:
And just for fun another instance of the Great Wave Off Kanagawa in the form of the Great Wave of Coffee
Back to almost full schedule this week. Two times running and at least one time indoor rowing in the gym.
Almost attempted to swim across the lake on Sunday as air temperature suggested spring. But water was still bit too low at 5ºC for a full roundtrip. But swam about 7 minutes.
looking forward to a week of vacation next week and working from the countryside the week after \o/
Still not finished with my current book „Die Illusion der Vernunft“. Was too tired and lazy to read the last two weeks. Need to pick this up again. The books isn‘t that bad that I want to rather quit it. I‘m actually interested in the topic. But apparently its not enticing enough to take the time.
For a reason I will reveal later I‘ve started reading a biography of Mustafa Kemal Atatürk. Very interesting so far.
No, not music. In general. Listening to understand. I noticed that the majority of people donn‘t listen to understand. If at all, they listen to catch the pause in the speakers flow of words to place their own words. Rarely anyone tries to listen to understand. That may include asking questions to clarify things that one doesn‘t understand.
I know this is rather late for the weekly review. The judges are paying attention:
should probably try to get this done on Saturday or even Friday, as Sundays are usually packed with getting back from the countryside to Berlin and getting everything ready for the new work/school week.
Took a look at Logseq as a note taking tool as @moellus was advocating for it. He provided some articles where people described their use of the tool. Main selling point seem to be thats it open source, uses Markdown as text format, synchronises across devices via iCloud or Dropbox and others.
again a lazy week as I only got the weekly lake swimming done, but no running, rowing etc. 🙁
Was contemplating about Pixelfed. While I like the UI as it resembles mostly the old working Instagram UI I less and less get the point of running my own Pixelfed instance. The level of interaction on the instance is really low compared to the feedback/interaction I’m getting for stuff posted on my Mastodon instance. Since Pixelfed ist just another Fediverse Service that can be consumed with most Fediverse clients, most people might just consume a main Stream on Mastodon and don’t want to follow a separate stream on Pixelfed. One can perfectly follow people on Pixelfed from a Mastodon account. Thats the whole point of the Fediverse. I can also follow my Mastodon Followings on Pixelfed. But I’m honestly too lazy to re-follow all the people in Pixelfed again.
To me, the Pixelfed mobile app as a special interest Fediverse client would probably be enough. An Instagram-like user interface that would only display ActivityPub posts which contain Images and Videos (maybe even more specific). So one can have the Insta UI but using a Mastodon Account. I don’t need to run or have an account on a Pixelfed instance for this. Of course currently the Pixelfed mobile app isn’t compatible with a Mastodon feed.
Obviously didn’t manage to get the weekly review done before Sunday. Weekend was rather busy as the weather finally felt spring-like and we got a lot stuff done on the property and in the garden.
We put in a tree to hopefully give us some shade in the summer (not this year, but maybe next year already)
replanted the tomatoes seedlings and also cleaned up the property. Since we had borrowed a large trailer over the weekend I was able to bring a lot of old stuff and trash to the local recycling yard. It’s amazing that you can just got there and get easily rid of most of your stuff that doesn’t belong or fit into the normal trash bins. Its free as its included in our yearly waste treatment fee. I’m always tempted to rummage trough the large scrap containers and get out useful stuff (like old electronics).
This week I’ve installed my own instance of Overleaf – a web based LaTeX editor for collaboration. Not that I’m in need of LaTeX document system at the moment… but it’s always nice to play around with such stuff.
Mastodon updated to v4.1.1
Installed a Jenkins-Cron-Job to repopulate replies to my mastodon instance as suggested by Matt.
Got quite a bit of 3D printing done. Leveled my printbed properly and I’m still amazed how smooth prints come out with the right filament and settings on this rather cheap printer. Uploading the timelapse videos to my PeerTube Instance in their own channel.
I switched to a newer version of OctoPi and it was just really smooth. Simply download a backup bundle on the old instance and feed that to the setup wizard on the new instance. Thats it. Everything was just there again. No need to change our touch a single thing. I could just go on-printing.
Gina Häußge (aka @firstname.lastname@example.org ) is really doing a fantastic job with this piece of software.
Oh boy was I lazy this week. Almost no sport at all. Running partner still sick, office gym showers closed and me too lazy.
On Friday my daughter an me joined the #FridaysForFuture gang for a nationwide climate justice demonstration in the Berlin.
In Berlin there were reportedly about 18.000 people on the streets. First there were a couple of speeches at the Invalidenpark and some musician were playing. The ones that stood out for me were Santiago Rodriguez and “Provinz”
One important topic was the upcoming public vote (Volksentscheid) on Berlin Climate Neutral by 2023. I hope you all got your vote notification and do you cross at the right spot. We need to push the government to do the right stuff.
Finally fired up the 3D printer last week to print another one of the moon globe lamp. That print took almost 2 days to finish. Now need to print the remaining parts for the stand and assemble it.
Started running again after 2 weeks ob absence. Felt good, but also rusty… I’m gettting old I guess.
Also started to do the indoor rowing again in the office gym. Feels good to get back into it and feel the old muscles getting stretched again.
And we were lucky on Sunday that there was no ice on the lake. It was still frozen on Thursday. So the water was pretty chilly but I managed to swim for about 4:30 min. Temperature outside and inside the water was ~ 2ºC.
Even my wife joined us this time and went into the water 3 times and took a few strokes of swimming. Wearing a neoprene suite, but nevertheless. Knowing that she’s suffering from severe ME/CFS for the last 4 years, this is a big deal for her.
A friend of mine asked whether I’d join them to find a sophisticated geocache inside one of the old soviet bunkers in the area. Since we really didn’t had anything else important to do on sunday morning, my daughter and me joined. The entrance was a venting pipe that wasn’t designed for chubby unicorns like me. But with a bit of wiggling it fitted through 😉
I’m currently reading “” and found some memorable quotes
Diese und andere ähnliche Heuristiken legen ein übergeordnetes Prinzip in der Entscheidungsfindung nahe, das der Wirtschaftswissenschaftler und Nobelpreisträger Daniel Kahneman als Verfügbarkeitsheuristik oder auch WYSIATI bezeichnet hat. WYSIATI steht für What you see is all there is (auf Deutsch: Was du siehst, ist alles, was es gibt) und meint unsere Tendenz, uns bei Entscheidungen auf die Informationen zu verlassen, die gerade verfügbar sind, statt noch umständlich nach weiteren Informationen zu suchen.
no Sport this week due to reasons. Now swimming on last Sunday due to too thick ice on the lake.
finally got some 3D printing done again. Tried out the new release of the PrusaSlicer which now sports organic support structures. Means, it will generate support structures that look like organically grown trees to support the overhanging parts of the models. This will save time during printing and also a great deal of material.
There are quite a bunch of Fediverse services meanwhile. And it’s nice that one can have a Twitter-like experience on Mastodon, an Instagram-like experience on Pixelfed, a GoodReads-like experience on BookWyrm etc.
But what slightly annoys me is the fact that it’s all separate accounts. People would have to follow several accounts of me to consume the various content types. Wouldn’t it be nicer if it would be just one account to follow and maybe just select the type of content that you wanna see? WordPress has different types of posts. What if WordPress would be fully Fediverse capable and could be used as the single account home instance. I would use the Pixelfed client to post pictures there and consume a stream of pictures from other people I follow. I would use one of the many Mastodon clients to consume a Twitter-like feed. Or I’d go to the web page itself (the Blog) to consume all content types at once.
This week got a bit messed up as I didn’t made it into the office. So I missed my rowing sessions in the gym. Also missed the running with a friend on Monday as it was rather icy and slippery outside. But towards the end of the week I got my cadaver out two days in a row for running in the park at least. First day I really felt the rust. Second day, although there wasn’t any rest day in between was much better.
On Sunday we were swimming in the lake and had to toss off some ice. The lake was almost covered with a thin layer, but fortunately near the beach it was open.
Our oven broke the second time now in about 8 years. Every 4 years the lower heater seem to burn out. Last time I had it repaired for about 180 EUR. This time, with some hints from the Fediverse I managed to swap out the heat pipe myself. So the whole repair was only 20 EUR. Hope it lasts the next 4 years at least.
Disclaimer: This is seriously dangerous stuff if you don’t know what you’re doing. The kitchen ovens usually have their own dedicate power circuit and fuses because they draw so much power. This is current that can and will kill you if you make mistakes. So please don’t try this at home unless you’re qualified.
Since the Pinafore Web-Based Mastodon client is discontinued, everyone seems to gravitate towards Elk as a replace. The elk team is building a rather beautiful web client for the fediverse. It can be tried out on their own instance at https://elk.zone/ or one can host it herself.
I tried the latter and built the Docker container to run the service. There are some caveats to that. The documentation is still rather sparse and doesn’t mention that the service must be accessed via HTTPS and also need a proper domain name. But thanks to Boerge I moved past that hurdle and got it somehow working. Of course not after some more struggle with file permissions in the Docker container. I submitted a Pull Request to the Elk team to fix the documentation and docker-compose.yml. Let’s see when this makes it into the main branch.
when adding new entries to .env for a docker-compose.yml .. make sure you put them also into the environment: section of your service to actually make use of them. Was searching for quite some time why my Minio didn’t properly made use of Prometheus …
Mattermost has finally release their Mobile app in Version 2.x. Most notable feature is the support for multiple Mattermost servers. This is very important as the self-hosted Slack-alternative grew rather popular the last years and the likelihood that you have to use multiple is increasing.
tried out the new 7.51 firmware from the FritzLab for my ancient Fritz!Box 7490. Seems to have wifi issues with my setup. So I switched back after about 1 day
on track with running 2x per week
trying to get more rowing done if time permits
swimming in the lake at 1.5ºC water temp on Sunday
visited the Museum Barberini in Postdam. Nice collection of famous impressionist pictures
stunning that most of the pictures didn’t even had protective glas. You could really see all the great details of the pictures. There were watch guards in every room though.
we used the VIP treatment and were able to get right into museum with the car.
on thursday I had to pick up my daughter somewhere in Neukölln. The usual route was blocked due to some blockage on the Ringbahn so I had to travel the U1 and U8 route in Neukölln. Quite a different world from Friedrichshain. There are so many small shops of different purposes. I wonder how they thrive at this size in this economy.
one very important question for product managers to decide the priority of a certain feature is: “Whats the business value of this feature?”
It can be further specified with questions like “How exactly does this make our product better?”, “Which problem does it solve?”
If you don’t have a very clear answer to these questions, then you’ll have a problem with the delivery of that feature.
finished reading “The Dark forest” and started the third volume of the trilogy “Death’s end”
On monday my Mastodon server acted up. I noticed that images were not properly loading but only displaying a blurry preview. But not all of them, just some. I suspected issues with the Object Storage Provider IONOS that I had recently configured.
After some digging I found out that my host couldn’t resolve DNS names anymore. Somehow the resolver died. So I rebooted the whole machine … not remembering that I had unfinished business in /etc/fstab which shadow mounted my home directory causing new weird issues …
In the wake of blaming the external object storage provider I had started looking into open-source alternatives. Like open-source software to set up a self-hosted S3-compatible object store. Stumbled over minio.io and quickly did a test installation on one of my machines at home.
After fixing all the issue on my server and finishing the setup of minio, I was ready to test it on some real live services: my personal Pixelfed instance. Since I’m the only user on that one, I considered it a safe playground. After a few rounds of trail and error (Pixelfed documentation still gives me the shivers) I’ve got the configuration right and test postings worked as expected.
Ready for prime time
I had configured my Mastodon instance at https://hub.uckermark.social/ to use external object storage provider for media content. The reason is, that Mastodon caches all the media in posts it federates. This can grow to several gigabytes very quickly. The more users on remote instances you local users follow, the more content the Mastodon instance will cache.
I followed the article of Thomas Leister, admin of the Mastodon instance https://metalhead.club/ to configure the S3 compatible storage from IONOS. While that technically worked out, I wasn’t really happy with the IONOS administration interface. They currently do not show any metrics for the object storage nor the data transfer. That means, flying blind for using their service until the invoice arrives. They claimed to have a billing API where the data is supposedly available. I had a brief look at it and decided that I’m too lazy to go that route.
So when IONOS issued the warning, that my trial period will run out in a few days I have decided to switch also my Mastodon instance to my self-hosted object storage backed by Minio. I copied over the existing data from IONOS object storage using the Minio Command Client. That is really comfortable.
I’ve also hooked up my minio server to Prometheus and Grafana for insights into the usage
To fight some of the kilos and the rust in general I’ll try to move more. Started that pledge with a run on Sunday. Wanted to start light with maybe 5 km to get back into it. Of course I overdid it with 10.99 km. Payed the price with sore muscles for 2 days.
While our weekly swim in the lake doesn’t count as much moving maybe, we still did it and I spent 3:12 min in the water. I’m heavily cursing at myself and the world when getting into the water. That part doesn’t get easier. But after 3 strokes of swimming thats forgotten and all that remains is the good feeling of beating oneself.
On Wednesday I finally sorted out my access to our office Gym and hit the rowing machine for 30 min and 7 km.
The historical facts of the Middle Ages and the Great Ravine prove that a totalitarian system is the greatest barrier to human progress. Starship Earth requires vibrant new ideas and innovation, and this can only be accomplished through the establishment of a society that fully respects freedom and individuality.

In den vergangenen Wochen hatte ich mal Warp als Terminal getestet. Dafür gabs Einladungen und man musste sich da irgendwie für die Beta Anmelden. Anfangs sah das auch alles ganz schick aus, aber mir kam es schon gleich etwas komisch vor, dass da so ein Hype mit Einladung und künstlicher Verknappung gemacht wurde. Dann vielen mir einige Settings auf, die ich auch nicht mag. Z.B. das Warp als SSH-client eine eigene Implementierung nutzt, damit es im Output seine Blocks verwenden kann. Heißt für mich, das mein ganzer SSH-Traffic durch einen SSH-Client geht von einer Firma bei der noch nicht wirklich klar ist, welche Absichten sie hat.
Jedenfalls bin ich erst einmal wieder zurück zu iTerm2. Da weiß ich was ich hab 😉 Warp werde ich dennoch weiter aus dem Augenwinkel beobachten.
Jan Lehnardt apparently had too much spare time over the holidays. So he did what Janl does and created a search engine for ones own Mastodon timeline: Searchtodon
