Nice: Cucumber 9.0 (the version of it, contains a bug fix I provided 😊: It no longer fails with an exception if you have $CUCUMBER_COLORS defined.

What a lovely idea by

I signed up as a mentor. Will you? Or are you looking for a mentor? This might be a great place to start.

Would you like to improve your programming skills online? I recommend trying It's free and you can get feedback from real humans (if you're in the track, may be even from me 😀 ).

I registered for Home Edition (11.-12. January).

Looking forward to learning (even) more

Potential spoiler for #AdventofCode Day 21 of 2022 

This is a case where the ability to define methods at runtime in was super helpful.
Also moving from the original problem to (iteratively) solving an equation enabled finding a solution even with WILDY wrong initial guesses. It's a GOOD THING applying nested intervals converges really quick (well, IF there is a solution…)

I just completed "Monkey in the Middle" - Day 11 - Advent of Code 2022

Phew. Intuition (and math) helped in keeping the numbers in part two from becoming astoundingly HUGE. It also limited the computing time to ≲ 11 sec overall, instead of 16 sec for the first ≈200 rounds. At that point the minimum worry was about 4000 digits long, the maximum more than 75 million. At that point arithmetic operation get a tad bit slow in . 😃

Side note: As frustrating as it is to stumble into self-developed bugs, it is nice to have the time to fiddle with the Advent of Code puzzles. It's creative, and I learn something new about nearly each day. Today: When a Struct is useful – and when it's not.

Oh nice, I'm an 'Exercism Super Mentor' 😊

Got this for my mentoring in the track of


Ruby is my go-to language for building APIs. The syntax is clean and readable, and the libraries and frameworks make it easy to work with.


What I don't understand:
Installing gems in a action works with 3.1.2, but fails with 3.1.3 – unless I use `bundler-cache: false` in the Ruby setup step.

Here's the error message – that doesn't help me a lot:

Error: The process '/opt/hostedtoolcache/Ruby/3.1.3/x64/bin/bundle' failed with exit code 34
at ExecState._setResult (/home/runner/work/_actions/ruby/setup-ruby/v1/dist/index.js:5340:25)

Good morning !

If you're planning to attend my workshop 'Fast Feedback Using ', please bring a notebook, ideally with Ruby already installed. 👍

I wonder, if there's a way to get ruby-build to provide the most current (3.2.0-preview3 at the moment, see faster, than waiting for an update of the definitions in and then a release.

I wonder, if there is a way to get rbenv (or rather ruby-build) to provide the most current (3.2.0-preview3 at the moment, see faster than waiting for an update of the definitions in and then a release.

Since I just moved in at just now, let me give an :

Software development is a social activity

A social place intended as a chill hangout place for software testers, developers, or just about anyone involved in delivering software and who is interested in both the technical as well as the social side of things. is supported by the Association for Software Testing.
