It was tricky to get the DOIO Megalodon Triple Knob Macro Pad (the one that supports Bluetooth, in my case) working on macOS 26 Tahoe (MacBook Air M2).
It only charges and connects via 5V, i.e. a USB-A-to-C cable. A typical USB-C-to-C cable won't work.
The "B" on the back is for "Bluetooth". Pressing it makes the screen blink and probably puts the device in pairing mode?
The "R" is for "Reset". Pressing it supposedly reboots but does not reset. (Source)
I was going on a train journey, wanted something to read and wondered if there was anything with the premise "someone secretly invented Claude Code before LLMs were a thing and used it as a secret superpower".
Then I thought I'd try asking Claude to write it, as an experiment. The prompt was a sentence or two asking for a KEPUB (Kobo EPUB) with the given premise.
This Gist has that file, only converted (by Claude) to a more normal EPUB for compatibility, otherwise exactly as written with no human editing or further prompting. Click "View raw" to download it. Read it in e.g. Apple Books, on a Kindle or a Kobo.
Shared here because I think it's an interesting conversation piece.
Conceptually inspired by https://github.com/AlexZeitler/claude-ssh-image-skill.

Ruby/Rails i18n does not (per 2025-07-07) respect the HTML-safety of interpolated values, so you need to do this:
I18n.t("foo.bar", link: link_to("Help", help_path)).html_safe
Even though link_to returns a html_safe? string, it will be escaped unless we flag the entire string as safe.
Flagging the whole string is at best inelegant, but also opens up for XSS injection attacks.
Less likely, a translator will inject evil HTML into the translation strings themselves. (But they should not be able to, however unlikely.)

UPDATE: Now a gem: https://github.com/henrik/activemodel-with_conditions
Rails with_options will overwrite if and unless conditions. So this:
with_options(if: :outer_1?, unless: :outer_2?) do
validates :method, if: :inner_1?, unless: :inner_2?
