There is a relevant Wikipedia page about minifloats [0]

> The smallest possible float size that follows all IEEE principles, including normalized numbers, subnormal numbers, signed zero, signed infinity, and multiple NaN values, is a 4-bit float with 1-bit sign, 2-bit exponent, and 1-bit mantissa.

Have you tried `firefox --no-remote --profile `?

In my case, I am able to launch several Firefox instances with distinct profiles.

New comment by conaclos in "Notes on switching to Helix from Vim"

conaclos — Fri, 10 Oct 2025 22:18:22 +0000

I tried Helix two years ago, unfortunately the default keymap was a bit frustrating to me. I don't mind changing my habits, however I had difficulty I made sense of the keymap design.

For example, typing `w` select the word. However, typing `2w` select the second word and not two words. To select two words you have to enter in visual mode (`v2w`). To remove two words you thus need to type `v2wd` or `wdwd`. In Vim you can type `d2w`. I miss this composability. In Kakoune (one of the main inspiration of Helix), you can type `2Wd` (`2wd` has the same behavior as Helix).

I was also hoping that the use of Ctrl/Alt modifiers be completely removed. Why not fully embrace modal editing?

If I remember correctly, TCO is now part of the ECMAScript standard. Safari has implemented it. The issue is that others engines have not because they are concerned about stack unwinding and stacktraces.

New comment by conaclos in "Show HN: Bolt – A super-fast, statically-typed scripting language written in C"

conaclos — Mon, 11 Aug 2025 00:21:14 +0000

I was quite excited by the description and then I noted that Bolt heavily relies on double floating point numbers. I am quite disappointed because this doesn't allow me to use Bolt in my context: embedded systems where floating point numbers are rarely supported... So I realized that I misinterpreted `embedded`.

I like the idea of repeating the delimiter on every line. However `//` looks like a comment to me. I could simply choose double quote:

    const still_raw =
        "const raw =
        "    "Roses are red
        "    "  Violets are blue,
        "    "Sugar is sweet
        "    "  And so are you.
        "    "
        ";
        "
    ;

This cannot be confused with a string literal because a string literal cannot contain newline feeds.

Yes, and I think it's unlikely that it will support other platforms in future because it's based on Safari.

Perhaps the most valuable paragraph of this sad story.

It is a RP2040. We plan to eventually upgrade to RP2350B.

I am currently working on an embedded system with 264Kb of RAM and 4Mb of flash. Do you think Lua could be used in such limited settings? I am also considering the berry scripting language [0].

Is Sol2 a Lua VM or just a wrapper to the standard Lua VM?

I am a bit surprised that the author didn't try to implement a stream parser. This could avoid loading the entire file in memory or relying on OS features like memory-mapped files.

Sure, but it's an additional dependency. I would prefer it if some of this machinery were added to `core`.

Thanks for sharing!

The only thing I disagree with is error wrapping. While I agree that the main error should not expose dependencies, I find it useful to keep a `cause` field that corresponds to the inner error. It's important to trace the origin of an error and have more context about it. By the way, Rust's [Error] trait has a dedicated `cause` method for that!

I accept, however this requires to create many types with corresponding implementations (`impl From`, `impl Display`, ...). This is a lot of boilerplate.

Hi! Biome core contributor here.

It could be nice to have a more descriptive title like:

    "Biome 2: first type-aware linter that doesn't require TSC"

Some details about this reelase:

- Type-aware lint rules

- Plugins

- Monorepo support

- Revamped, configurable import sorting

- Linter domains

- Bulk suppressions

- Analyzer assist
