Had a productive weekend. Could release PrivateBin 1.7.2, which includes a new template, as well as convert2json 0.8.4. And I had a nice bike tour around the nearby Greifensee.
A classic bug for a leap day: At work, colleagues discovered and fixed a bug in a lesser used tool that only occurs on February 29th. It did trip up the tests, so no one got to merge until it got identified and resolved.
The source file in question hadn't been touched in over 4 years. Last leap year, the 29th was on a Saturday, so likely no one noticed.
What was annoying is that the logic had been clearly written with the intent of handling leap years. A leap year check condition was present, validated only on a February > 28th, but had to get inverted.
You may wonder why we wouldn't have used the languages' standard library date functions to validate the date - unfortunately the language in question doesn't have such a sophisticated standard library (language omitted to protect the innocent).
In order not to spam everyone, here just one post linking to the photos from my holiday in Peru. Feel free to comment or ask if you're interested in more details. Sharing this here as I could not do so via the tour groups whatsapp.

As you can imagine, I greatly enjoyed this trip. There is so much more history to learn about and archeological sites to see than I imagined. Food and people are great, and I only regret that my Spanish is so basic that I could not chat more with the locals. Yes, I did try Cuy (guinea pig) & Alpaka, and no, they don't taste like chicken at all.
I like CSS-animations, clocks and dials for making metrics easier to digest (we are quicker at detecting angular changes than reading and parsing digits). So I'm in awe with this creative use of a watch-dial to visualize a 32-bit hexadecimal number:
At work we use more and more YAML documents (with all it's benefits and issues) so I've long started using a handy python alias to convert them into JSON to query them using jq:
alias yaml2json='python3 -c '\''import sys, yaml, json; y=yaml.safe_load(sys.stdin.read()); print(json.dumps(y))'\'''
Because we also started using it in the test harness to validate YAML documents, we made it available to that environment as well. Test creates some YAML report, which is piped into yaml2json, which is piped into jq --exit-status '[...tests here...]'.
Fast forward a few months, more tests got added, and eventually I notice that one of these, on a 30k line document, spends about 15 seconds just converting it. Hm.
Now, it's not like there are not already tons of C, C++, Go, Rust, etc. versions of that tool around, I'm aware of many of those, unfortunately none are p

Now, it's not like there are not already tons of C, C++, Go, Rust, etc. versions of that tool around, I'm aware of many of those, unfortunately none are prepackaged for the distro used around here. Still, it nags me. I know that in Rust we have all these convenient Serde libraries. Would be trivial to write it using these. People have done so. Hm. And we could make a little wrapper around jq, like yq (python), which makes it easier to use. And we could also support other formats, like XML or CSV, like yq (Go) - the latter also replicates jq itself, that seems a step too far and risks running into incompatibilities, jq itself does the job alright.
So, eventually I did put these puzzle pieces together and we have yet-another-format-to-JSON-converter: github.com/simonrupf/convert2j…
Unique selling points? Well I've experimented a bit with github actions and it is indeed not to difficult to automate the release and publication of statically linked RPMs (for use on different RPM-based distros) and dynamically linked binaries for Ubuntu, MacOS (universal binaries for x86_64 & aarch64) and even Windows (untested - I have no access to that OS, nor do I want to). I'll try to keep it light weight and have some automation set up to keep it updated when dependencies change.
And yes, that 30k YAML file now parses in 0.2s instead of 13s. OCD satisfied.

Oh, wow: Nachdem ich von den beiden Druckwellen des Vulkanausbruches in der Nähe von Tonga hörte, habe ich in den Messungen von meiner kleinen Wetterstation nachgeguckt und die sind dort klar zu erkennen!
Hach, das war damals das erste Meme dem ich im Web über den Weg gelaufen bin. Schön, dass Archive.org daran arbeitet Flash-Animationen auch für künftige Generationen zu erhalten! #MakeTheWebWeirdAgain
Liebe Freunde des gepflegten Alteisens! Kommendes Wochenende ist Vintage Computing Festival Berlin 2020 vcfb.de/2020/), und ihr könnt das alle besuchen, ohne auch nur einen einzigen Fuß vor die Tür zu tun. Ich bin dieses Jahr leider nur passiv dabei. Schade finde ich insbesondere, dass dieses Jahr die Fotografiererei auf der Strecke bleiben wird: flickr.com/search/?user_id=529… #vintagecomputing #retrocomputing #vcfberlin #vcfb
Falls Du einen hast und das Display noch funktioniert - Quietscht Deiner auch so, beim Aufklappen? Bei meinem habe ich deswegen versucht das Scharnier etwas zu ölen, aber es ist immer noch recht laut. Auch habe ich den Bolzen wie im PoFo-Wiki beschrieben bearbeitet, um hoffentlich die Lebensdauer des Bildschirmkabels etwas zu verlängern.
Weil es mal echt an der Zeit ist: Danke an Euch alle, die Ihr das Netz mit Euren Instanzen verschiedenster freier Software auch und gerade in dieser Zeit so nützlich macht. Danke für alle Helfer und Maintainer des freien Internets. Danke #Fediverse #floss #bleibtwachsam #decentralisation
Seien wir froh, müssen wir uns nur mit den modernen Datums- & Zeit-Problemen herumschlagen. Hier hat jemand eine ähnliche Liste mit Ausnahmen in alt-römischen Kalender-Problemen zusammengetragen:
Meine Eindruck vom Congress: Das ist hier wie das Internet in den 90ern - bunt und animiert, wild, frei, mal laut, mal zum Nachdenken, man merkt gar nicht wie die Zeit verfliegt und es gibt immer noch mehr zu entdecken. Ein riesen Spass! #36c3
#UltimaThule is the first primordial contact-binary ever explored up-close by a spacecraft, meaning it was once two separate objects that are now bound together. It is a pristine specimen, preserved as it was formed. Other similarly shaped objects have been modified over time due to their closer proximity to the Sun.

Nach langer Reise erreichte mich ein Mondstein aus China. Der polierte Stein hat eine recht niedrige Qualität. Nur wenn man ihn gegen das Licht hält, kann man im Innern einige perlmuttartig schimmernde Einschlüsse erkennen, die einen Mondstein auszeichnen. Dafür ist der Brocken recht gross.
Aus Hong Kong erreicht mich ein Elefanten-Anhänger mit abgebrochenem Rüssel. Die Briefmarke ziert ein Schachwürger ("long-tailed shrike", Lanius schach schach).
