Released version 0.0.5 of the command line kptncook scraping tool based on the work to reverse the kptncook api from Daniel. It's now possible to fetch recipe metadata just by providing the sharing url of a recipe from the kptncook app. It's also possible to download all stored favorites and backup them locally or import them to mealie.

After listeing to LOV021 Podlove-API mit Dirk Schumann I realised it might be possible to use the podlovers podcast frontend also for django-cast because it doesn't depend directly on wordpress anymore. This is very exciting, because having to use php/wordpress was the main reason keeping me from looking more closely into the whole podlove ecosystem. The only thing I have to do is to write an adapter for the api (and there are some parts missing as well like transcripts and contributors). But at first I have to be able to test and understand the existing api locally. Therefore my aversion for wordpress led me to having to use it finally. In the end it wasn't that difficult at all and I took some notes on how to reproduce that. File handling is not working yet, but I'm sure to figure it out next week.

Podcasts

• Episode 51: Moral Subjectivity (Hotel Bar Sessions) | This whole episode is about two pages from "On the Genealogy of Morality" by Nietzsche - kind of a new format and I like it a lot
• Folge 115 - Data Mesh - nur ein neuer Datenanalyse-Hype? (Software Architektur im Stream) | Found an exception to the "if there's a question mark in the headline, the answer is always no"-rule :). Maybe I was framed by the bad audio quality into seeing flaws everywhere, but well, at least I do know now what people are talking about when they speak about data mesh.
• Django’s Rough Edges - Keryn Knight (Django Chat) | Good as always
• LOV021 Podlove-API mit Dirk Schumann (https://podlovers.org) | Very exciting episode (at least for me), because it seems like podlove is going to expose all its functionality via an api. Which means that I could use the podlove frontend (if there is such a thing) together with django-cast if I just implement the same api on the backend side, which shouldn't be that difficult (famous last words)..

• Vom Pilgern und Fasten - Wie Religion heute noch funktionieren kann (Hörsaal) | I'm not religious at all, but there were some interesting facts in this episode. For example: In .de the number of members of the catholic church is in constant decline since at least 70 years. But globally the number of members is increasing. It's growing even if you correct for population growth. Fascinating. I also didn't know that there is no commonly accepted definition of religion in the social sciences.
• Glaube und Wissenschaft - Die Grenzen unseres Wissens (Hörsaal) | This talk is odd. The main conclusion "We don't know everything therefore we should consider a thing we like to believe as possible" (which has nothing to do with physics and everything with wishful thinking) is clearly wrong. What bothers me is the deceptive nature of this talk, trying to use physics jargon to bullshit the audience. This talk shouldn't have passed the editors of this podcast.
• Episode 49: Memory (Hotel Bar Sessions) | Great, iirc
• Revision 525: Beyond Tellerrand und andere Konferenzen in Zeiten von Corona (Working Draft) | Episode about the beyond tellerrand conference which will be next week in Düsseldorf (I will be there, too)

Met a lot of people last week. Spent the first half of the week going to this years PyCon DE despite I thought I wouldn't. This was really cool (day 1, day 2, day 3). After that I spent the last half of the week attending family appointments. Avoided to catch fire / covid, ffp2 ftw. Somebody was more successful than me reversing the kptncook app and opened an github issue to notify me about that. How awesome is that? As soon as I'll be able to spent more time on computer stuff I'm going to enhance my kptncook-scraper accordingly.

Things I Learned

• auto_error in fastAPI allows you to test for different authentication methods (cookie, bearer token, etc), but using an authentication middleware as in django is probably a cleaner solution
• It's not possible to return values from dependencies declared at router level in fastapi, but you could attach stuff to the request and use it as a container for additional state

Articles

• Weeklog from Johannes

Recorded and produced a new podcast episode about microservices. For my podcast hosting project I need some place to store podcast episodes and therefore I finally automated the setup of minio. Let see if it will be fast enough :). Did a bugfix release of kptncook. And started to collect information about deployed services which then could be used by other services doing logging, monitoring or backup.

Things I Learned

• If you don't want to run your minio installation publicly this ssh-portforwarding command works (you have to change username and ports): ssh -v -L  10000:127.0.0.1:10000 -L 10001:127.0.0.1:10001 minio@staging.wersdoerfer.de

• WR1347 Bruttointelligenzprodukt (WRINT - Wissenschaft)
• WR1349 Embargo: Modelle, Zölle, Anreize (WRINT - Wirtschaftskunde) | What I like most about this podcast is to get a glance at the economic viewpoint, which is usually really foreign to me. Highlights: Maybe just use tariffs and form a price cartel to rob gas/oil from russia (they have to go down with their own price to be able to sell at market price). Those who scream loudest about oil/gas from russia being not substitutable are those who are most afraid of being substituted.
• Intelligente Kraken - Aliens mit neun Gehirnen (Sein und Streit) | Octopus cannot see color with their eyes, but with their arms :€ and the information about color and ground structure does not need to be transferred to the central brain, because each arm has one (bigger than the central one). They build "houses" with an individual aesthetic and get angry if you mess it up.
• Machtvoll? - Kunstwerke (Das philosophische Radio) | It's weird, every time I listen to Markus Gabriel talking about abstract topics I'm not familiar with, I'm thinking: Hmm, interesting and eloquent. Everytime I hear him say concrete things about topics I know about (computer stuff), I'm like: Wow, this is complete bullshit. Not sure what to make of this. But there were a lot of intereting definitions of art: From having no intent/purpose (Kant) to showing how things really are (which needs to be intentional, Klee) to art is the definition of art (Kosuth). Kept me entertained at least while doing sports.

Interesting numbers from this episode: infection fatality rate did go down from 1.5% (begin) to 0.11% (now) which is comparable with the flue.. of course there are far more covid infections so it's not the same risk.. for every person dying from covid there's on which dies in hospital from a different cause, but was tested covid positiv
