The LED in this picture is 1080-EAST2012RA1CT-ND on digikey, which quotes 45-112mcd (depending on bin?) at 20mA, so probably in the same ballpark as the JLC basic red led.

So yeah, maybe you could get that green one to start glowing at an even lower threshold :D

Note to self: JLCPCB basic parts green LED (KT-0805G) is INSANELY bright. Especially compared to the basic parts red LED (NCD0805R1)

If you look in the datasheet, red has a typical luminous intensity of 115mcd at 20mA while green is 300mcd at just 5mA. That's 3x the brightness at 1/4 the current 🤯

I'm unreasonably excited about the upcoming cargo-semver-checks release: this month we put some points into "make it a joy to use and build."

- 3x faster at scanning very large crates
- its `cargo test` now takes 1min not 6-7min
- we gracefully handled a massive change in the rustdoc JSON format

I know I poke fun at the evangelism, but I’m finally taking the plunge to learn #Rust. It’s broken the TIOBE top 20 list (www.tiobe.com/tiobe-index/), and I’m starting to see some adoption in the #microcontroller world. I really like Brown’s interactive version of “The Book” - rust-book.cs.brown.edu

Always happy to chat :)

Berlin in the summer time is definitely something special :)

Ayyyy, congrats :D

I'm pretty sure I saw this on Reddit and that someone checked out the diamond code for "1203" and it was just unleaded gasoline.

You probably should not drink gasoline.

TIL warp factors are logarithmic

fmt.rs GitHub Gist: instantly share code, notes, and snippets.

Yeah, that might be more clear!

I'm planning on doing something like this, until I figure out how to do a more clever thing in the future: gist.github.com/jamesmunns/1...

(the clever thing I want to do is basically defmt, but with Serialize instead of defmt::Format for fields)

Yeah, it'll probably end up being something like:

```
log!(NET_STACK, "boop {}", 42).await;
```

instead.

Simple postfix macros by joshtriplett · Pull Request #2442 · rust-lang/rfcs This RFC introduces simple postfix macros, of the form expr.ident!(), to make macro invocations more readable and maintainable in left-to-right method chains. In particular, this proposal will make...

There's been some discussion about it, I think just "drawing the rest of the owl" of doing the syntax design.

There's github.com/rust-lang/rf..., but it's a "long open" one. There was some interest after `?` and `.await` landed, but afaik it never got going seriously.

It's a static that gets declared at the global level in a user's application/binary crate:

github.com/jamesmunns/e...

I do wish we had postfix macros in Rust. It would be awesome to be able to do something like:

NETSTACK
.log!("hello: {}", 42)
.await;

If you have specific ideas in mind, lemme know, happy to collab on something :)

I decided to do that like 7 years ago, I'm still shaving that yak. I finally have a network stack I'm mostly happy with.

For embedded: this is serial port libraries and debugger libraries.

I'm sure every industry has their own version of this. It's just a funny pattern to see, and I have no idea how to improve "the commons" on these topics.

Every now and again, a new hero arises, and it's good for a while.

There's also almost never any money in this: it's thankless plumbing. SOME special cases will exist, where there are boutique pro-tools. For open source stuff? It's just sort of thankless arcane plumbing.

All with everyone playing "not it", because they don't want to own it.

They end up being like... the worst software out there, because:

* If you touch it, you own it - they need help maintaining
* If you do help, you will be overwhelmed by people asking why it doesn't work for their thing, or asking you for help to make it work (whether there are docs or not)

There's a certain class of utilities that end up being a focal point of "awfulness":

* They require nontrivial knowledge to maintain/architect
* They are popular, may people, especially newcomers, interact with them
* They have an extremely long tail of special cases, that are not easily abstracted

Many people are saying this:

Did you all ever try out deno? Not sure how the comparison pile is between bun/deno/node

Dhall name drops en.wikipedia.org/wiki/Total_f...

Which certainly seems like something all these examples aim for, at least.

I wonder if templating languages like jinja count in this category, or ETL scripting langs, or whatever nix or dhall do

You make very cool stuff! I'm gunna have to figure out how to namecheck your load balancing post some day :D
