Counting the milliseconds

I’ve been building a Netty-based web server in Clojure. While I haven’t had the strength to do much with it these past few months because I prioritized the climbing season, now that Hacktoberfest is incoming I’m planning to go pedal to the metal with it (and with my git GUI work-in-progress).

I’m building iny (named after a fox from Fekete Istvan’s Vuk) with the clear goal to replace Aleph. While I’m a huge fan of Aleph and the libraries around it (like Manifold) it’s no longer maintained, which is simply not acceptable when we’re now looking at http/3 coming out sooner than later (support is already in browsers after all).




Going green

There is kind of a status to having your GitHub contributions chart covered in green. For those unfamiliar, it’s a calendar-like chart that shows how active you are on GitHub any given day. It’s assumed that the greener the better. I’m not so sure anymore.

From the start of May to the end of July, I tried filling it up. Do something every day. My conclusion is that this is a typical case of Goodhart’s law. Basically as soon as a certain metric (in this case turning that chart green) becomes a goal in itself, it ceases to be a meaningful metric anymore.



GitOps and Kubernetes persistence

A while back I wrote about bootstrapping a Kubernetes cluster. I’ve been refining the setup so that it requires as little manual kubectl‘ing as possible. I still use ArgoCD to get everything rolling, and there is one bit that kept going red: persistent volumes.


I got really fed up with sitting at home because of covid. So instead I rented a car and went for a snowy hike where I wouldn’t be likely to run into people: Mt Asama, an active volcano. In fact I only ran into 1-2 people on the way.

Tavaszi hó

Milyen jó is az, amikor télen próbálnék síelni menni, és minden sípálya félig-meddig üzemel csak, mert “meleg a tél” és “alig van hó”. Először egy félprofi panaszkodott erről a Hotaka síliftjén, aztán amikor Nozawára mentem, hogy akkor megtanulok sífutni, minden sífutás órát lemondtak a szezonra, mondván nincs elég hó. Utána a Nishi-Hotaka oldalában is kérdéses volt, hogy tudunk-e hótalpas túrázni (bár az végül sikerült).

Return to Kumotori

While other countries have pretty harsh lockdown rules (from what I hear on the news), Japan is pretty lax about that. While commuting to work by train is discouraged, I figured going up in the mountains (where there are hardly any people) it can’t hurt, right?

Training for Aconcagua

After Elbrus and Kilimanjaro, I knew I can’t take Aconcagua lightly. At almost 7000m it’s the highest mountain outside of Asia and thus the second highest of the Seven Summits. Working full time, the time I had available for training was very limited. This was before covid hit either, so I actually had to commute to the office too, which is about an hour one way. So what can the man do if he only has so many hours in the day and he needs some sleep too, but training has to be done for Aconcagua?
