Josef Strzibny: Auto-saving Rails forms with Turbo Streams
Here’s how to implement autosaving for inline input fields the Hotwire way.
[...]
I spent a considerable amount of time chasing an issue with wrong field focus. If that happens to you, go through all of your forms and make sure each input field has a unique ID. If you have two forms of the same model on the page they will have a different form ID but same input IDs.

Adam Young: GitPython do two files differ in different branches
Not quite as succinct as I would have liked, but this does work. This is a one liner in Bash, and I had hoped to do it with a single python call once I had the repo object established. In general, diffs are not simple to do on blob objects. I had trouble using the difflib and set approaches to diffing the two files, possibly due to the fact that I was originally not decoding the streams. Thus all the splitlines work probably can be simplified.

Andy Wingo: ephemerons vs generations in whippet
Happy new year, hackfolk! Today, a note about ephemerons. I thought I was done with them, but it seems they are not done with me. The question at hand is, how do we efficiently and correctly implement ephemerons in a generational collector? Whippet‘s answer turns out to be simple but subtle.
on oracles
The deal is, I want to be able to evaluate different collector constructions and configurations, and for that I need a performance oracle: a known point in performance space-time against which to compare the unknowns. For example, I want to know how a sticky mark-bit approach to generational collection does relative to the conventional state of the art. To do that, I need to build a conventional system to compare against! If I manage to do a good job building the conventional evacuating nursery, it will have similar performance characteristics as other nurseries in other unlike systems, and thus I can use it as a point of comparison, even to systems I haven’t personally run myself.

Mike Blumenkrantz: Rake In Bike
First Perf of the Year
I got a ticket last year about this game Everspace having bad perf on zink. I looked at it a little then, but it was the end of the year and I was busy doing other stuff. More important stuff. I definitely wasn’t just procrastinating.
In any case, I didn’t fix it last year, so I dusted it off the other day and got down to business. Unsurprisingly, it was still slow.
