Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

RFC 3339 vs. ISO 8601
A link was added from "Europe/Kiev" to "Europe/Kyiv" in the included-by-default backward file [0], so that any user that doesn't exclude that file will simply treat the old name as an alias for the new name.

Navigating the timezone nightmare in product development
"Eire" is in there, for instance, to deal with software that assumes that the "is_dst" half of the year is during the (northern) summer, but Ireland technically does it the other way around -- a distinction relevant only to computers.
https://github.com/eggert/tz/blob/c3e966c59b02b1f47f0b7b0e4a...
The only other timezone that currently has a non-1h offset for DST -- Ireland's is -1 hours -- is Australia/Lord_Howe, which has a 30-min positive leap.

Small parser for the tzdb text file format (based on Esrap)
I've looked at it, but wanted to work with the tz source repository directly (I think local-time gets their zone files from Ubuntu). Also getting zic running in a portable way seemed too much of a hassle. The text file format is not all that complicated and documented in the zic manual pretty well. This approach is also chosen by the JDK as far as I can tell.

Regional Daylight Saving Timezone changed but not reflected in Android
Unfortunately, you just wait. The person(s) at IANA who manages The Time Zone Database is certainly aware, and from there it "just" has to percolate down to Google and your phone.

What is your opinion of Daylight Saving Time?
And have you looked at the TZ database? My God it's a hot mess, and for good reason: human governments are terrible at creating code. Worse even than beginning CS students, because at least CS students know they don't know what they're doing, while politicians are both stupid and arrogant enough to think they're not stupid.

Embedded Swift on the Raspberry Pi Pico
probably, I didn't really check it, but I found [1]. Rust has a lot of support for embedded systems, even from the companies that provide the chips, like STM and Espressif.

I built a column staggered keyboard with firmware written in Rust!
About the same time, I was learning Rust and discovered how it could be used on embedded targets from Low Level Learning on YouTube, the video introduced me to the amazing rp-hal crate that provides abstractions to talk to the Raspberry Pi Pico microcontroller. Getting used to the no_std mode took some time, the most challenging was not being able to collect an iterator to a container.

The Rise of Rust, the ‘Viral’ Secure Programming Language That’s Taking Over Tech
What are you on about, can you clarify? Rust can compile in no-std/embedded style just as fine (or better) than C can for basically any ARM or RISCV based processor, and quick googling shows this hal for nearly all pi needs and even MEGA65 is "as supported" (read: not at all officially by anything, fan-only) as any current C compiler. Setting up rust for a new target, so long as the code-gen is supported somehow by LLVM, LLVM plugin, LLVM IR transpiler (and maybe libgcc-jit sort of soon) is just as painful or unpainful as setting up a whole team to work via C/C++ with comparable testing harnesses. This doesn't mean easy and is an area Rust is still improving rapidly by the various enterprise agencies (Ferrous systems, Oxide, more I can't remember...) who specifically want to bring rust to such low end hardware because frankly both C and C++ suck with vendor proprietary tool chains and quirks.

"pub use bare_metal::CriticalSection;" Error
He says he can't find crate for 'bare_metal'. He was setting up and testing the HAL for the pico (https://github.com/rp-rs/rp-hal). While compiling it pulls down critical-section-0.2.7/src/lib.rs and bars on line 7
