What a lovely idea by @andycroll ➙ https://firstrubyfriend.org

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

#RubyFriend

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

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

Looking forward to learning (even) more #Ruby

https://rubyconf.org/home-edition

It’s released: Ruby 3.2.0 ➙ https://www.ruby-lang.org/en/news/2022/12/25/ruby-3-2-0-released/

Merry #Ruby Christmas 🤶🎅🧑‍🎄

This is a case where the ability to define methods at runtime in #Ruby 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…)

Nice: You can apply to become part of the #RailsConf Program Committee (organisers: @railsconf) ➙ https://docs.google.com/forms/d/e/1FAIpQLScnEOkyXl8Ic-qyHNuwRbd8KeWouCyDglQm9bivmkZz6iKDDw/viewform

#Ruby and #Rails

I just completed "Monkey in the Middle" - Day 11 - Advent of Code 2022 #AdventOfCode https://adventofcode.com/2022/day/11

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 #Ruby. 😃

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 #Ruby 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 #Ruby track of https://exercism.org.

What I don't understand:
Installing gems in a #GitHub action works with #Ruby 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)
…
at Process.ChildProcess._handle.onexit (node:internal/child_process:301:5)

Oh there is a #Ruby 3.1.3 now. 👍

Good morning #agileTD!

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

A blog post about an alternative way to #parenthesise in #Ruby (that I don't recommend for production code) https://seasidetesting.com/2022/11/14/another-way-to-write-ruby-code/

I wonder, if there's a way to get ruby-build to provide the most current #RubyVersion (3.2.0-preview3 at the moment, see https://www.ruby-lang.org/en/news/2022/11/11/ruby-3-2-0-preview3-released/) faster, than waiting for an update of the #Ruby definitions in https://github.com/rbenv/ruby-build and then a release.

I wonder, if there is a way to get rbenv (or rather ruby-build) to provide the most current #RubyVersion (3.2.0-preview3 at the moment, see https://www.ruby-lang.org/en/news/2022/11/11/ruby-3-2-0-preview3-released/) faster than waiting for an update of the #Ruby definitions in https://github.com/rbenv/ruby-build and then a release.

Since I just moved in at https://sw-development-is.social just now, let me give an #introduction:

I'm a (mostly #Ruby) programming software tester, cancer survivor, (winter) swimmer - and more.

I studied physics, worked in oceanography and live near the North Sea.
