The XZ attack and timeline
29. October 2021 At this point Jia Tan pops up, and the first thing we see from him is an innocuous patch to the xz repository, and while a lot of people believe he started out trying his luck with another library also known as libarchive, this is not the case, I would bet it’s more of a backup looking at the dates, being that there are a few days in between as shown in this commit.

Making Amiga IFF Thumbnails Work in Linux
Full agreement, and with the addition of xpk¹/xfd² as natural extensions to that extensibility too. I see things like xfd supporting xz¹, and I'm simultaneously amazed that it exists and happy that I don't need to do xz {,de}compression on 68k ;)
I guess we have something similar-ish with libarchive⁴, but nobody(including me) has pushed the extra mile to get file dialogs to support random compression and decompression formats.
Beyond OT: I didn't realise how much stuff was still going on at aminet, but I love love LOVE that people are still dropping new car sets for Geoff Crammond's F1GP.

WinRAR zero-day exploited since April to hack trading accounts
I don't have a preview channel install handy to check, but apparently they're using libarchive so here's the full list assuming they expose everything it supports:

Cap'n Proto 1.0
I don't work at Cloudflare but follow their work and occasionally work on performance sensitive projects.
If I had to guess, they looked at the landscape a bit like I do and regarded Cap'n Proto, flatbuffers, SBE, etc. as being in one category apart from other data formats like Avro, protobuf, and the like.
So once you're committed to record'ish shaped (rather than columnar like Parquet) data that has an upfront parse time of zero (nominally, there could be marshalling if you transmogrify the field values on read), the list gets pretty short.
https://capnproto.org/news/2014-06-17-capnproto-flatbuffers-... goes into some of the trade-offs here.
Cap'n Proto was originally made for https://sandstorm.io/. That work (which Kenton has presumably done at Cloudflare since he's been employed there) eventually turned into Cloudflare workers.
Another consideration: https://github.com/google/flatbuffers/issues/2#issuecomment-...

How do AAA studios make update-compatible save systems?
If json files are a concern because of space, you can always look into something like protobuffers or flatbuffers. But whatever you use, you should try to find a solution where you don't have to think about the actual serialization/deserialization of your objects, and can just concentrate on the data.

Is using Flatbuffers to parse sensor data a bad application of Flatbuffers?
As the title suggests, I am considering using Flatbuffers as a way to parse sensor data that has been stored in local datafiles. The project language is python.
