Lfg my Swift YATA CRDT implementation is finally finished.
Slightly modified from things like YJS or Automerge. I’m optimizing for fast local use and small memory footprint, and sacrificing slower merge speed.
I can now get back to my data sync macro project with all my CRDTs finished.

Drove a little further south to the Louisville Swamp Trail and got there just a bit after peak but it was still gorgeous

Fun to see the cluster of northern-ish North America self hosters who are proxying through cloudflare with whom my PDS shares an IP

This butthead is so cuddly in the afternoon after biting my bicep so hard it left teeth marks and knocking over all the plants in the house this morning.
Gaslighting me into thinking he’s so kind 🤨

Realized the `Data` time had a typo and it was actually doing 1 million iterations so here's a more comparable time lmao

Obviously I also need to consider that if I entirely neglect to sort the dictionaries, there's still a very large disparity between my complex encoder and Apple's JSON encoder. So clearly there's other work to do beyond making sorting faster.

If I grab the upcoming swift-collections `SortedSet` off main (unoptimized, unsafe, don't use) I get marginal improvement and I think there's an optimization available here for reused maps in structs in particular. Maybe I can cache the order on a per-type-keyed-encoder-basis and reuse it

My Swift CBOR encoder is now 20-40% faster than Apple's JSON encoder (the new fast one) but I'm struggling to get dictionaries up to speed cause I wanted to sort them by default (required for a lot of applications, like dCBOR or DAG-CBOR).
Complex here is a series of nested structs

First attempt at an old family recipe for Honey Whole Wheat bread, turned out phenomenal. I left it rise about 4x as long as it needed the last rise, which I think caused it to collapse a little while baking, but turned out pretty good anyways!

Love making little automations in Factorio. This one uses just a clock and SR latch to alternate colors on my rockets!

Finished my first solo backpacking trip! The north shore is gorgeous, still my favorite region in the entire world.
Did about 12 miles total on the Superior Hiking Trail, with an extra half mile in there where I got lost on another trail. Rained a little overnight but still a great trip

I'm enjoying making Grafana dashboards for my home server WAY too much

I have too much time rn so I now have prometheus metrics for my PDS and whatever else I put on here in the future
