Bedrijf failliet: stalling deelscooters kost gemeente zeker zes ton

Posted by jpluimers on 2025/12/30

Bij disruption (Hallo Uber, Amazon, Zorgcowboys!) komen de kosten uiteindelijk vrijwel altijd op de maatschappij terecht.

Ook nu weer: [Wayback/Archive] Bedrijf failliet: stalling deelscooters kost gemeente zeker zes ton

De gemeente Hollands Kroon dreigt voor ruim 600.000 euro het schip in te gaan door het ruimen van zo’n 4000 scooters van het failliete deelscooterbedrijf Go Sharing. De Noord-Hollandse gemeente probeert de schade te verhalen op het bedrijf. Maar omdat Go Sharing enkele malen van eigenaar wisselde en in november failliet ging, is de kans op succes gering.

python – Some gists on github have very many forks. How can I find the most recently active and/or heavily modified? – Stack Overflow

Interesting read: there is even an API for it (which you need to be logged on for in order not to get a rate limit): [Wayback/Archive] python – Some gists on github have very many forks. How can I find the most recently active and/or heavily modified? – Stack Overflow

Thanks [Wayback/Archive] Michael Goldshteyn, [Wayback/Archive] rob006, [Wayback/Archive] Chankey Pathak and [Wayback/Archive] ikwyl6 for solving this both for gists and regular github repositories:

Structure and Interpretation of Test Cases • Kevlin Henney • GOTO 2022 – YouTube (hello Leap Years!)

Posted by jpluimers on 2025/12/30

Any session by Kevlin is great, so this is definitely recommended watching: [Wayback/Archive] Structure and Interpretation of Test Cases • Kevlin Henney • GOTO 2022 – YouTube

Via [Wayback/Archive] Ifeora Okechukwu on Twitter: “On the structure and interpretation of test cases: by @KevlinHenney Awesome talk!!! “.

A few takeaways:

  • Kevlin uses the same Leap Year case as I have taught since the mid 1990’s: I like the way we both approach software development, though I can still learn a lot from Kevlin.
  • Non-programmers understand more than you might expect, just like you can get much more from a foreign news paper than you would think at first thought
  • You should know how to draw a Venn diagram with 4 sets allowing *all* combinations of those (search for “Venn’s four-set diagram using ellipses” in the link on the left)
  • Kevlin shows these 4 sets:
    • Common cases
    • Simple cases
    • Boundary cases
    • Edge cases

    The first two and last two sound similar. They aren’t.

  • Wrinkles and various levels of code coverage: don’t fool yourself as that is easy to do
  • The way of thinking is “thorough” (note from self: AI is not thorough, it is statistics)
  • Calendars are difficult (and depending a lot on the period and region their usage are valid for) – I already knew that, but it was good to be reminded off; see presentations by Jon Skeet for more information on it, see the blog tag Jon Skeet, or for instance these links:
