@mrousavy Cool. Avoiding any rust to seep in?

50% of the stuff we do at Margelo is C++ work nowadays

@NateMatherson Those sheets are spread indeed

If your WFH desk setup doesn't cost more than a used Honda Civic, you aren't serious about your pipeline. My ergonomic chair is built from the salvaged suspension of a 2019 Tesla Model S. My primary monitor is a converted IMAX screen I bought from a bankrupt theater in Oakland. When I drag a cell in Google Sheets, I physically have to rotate my entire torso. I burn 400 active calories a day just searching for the Slack icon. Stop complaining about back pain and optimize your environment.

@pablogdcr @diogomartf @wcandillon @chrfalch That would be awesome !

@diogomartf @wcandillon @chrfalch I could make it open source if interested

Just rebuilt Apple’s iMessage text effects in React Native 🔥 Invisible Ink, Slam, Shimmer, Bounce, Glitch, and more. 60fps, buttery smooth with React Native Skia. All running natively on iOS & Android. This was only possible thanks to @wcandillon & @chrfalch ❤️ #ReactNative #Skia #iOS #MobileDev

@Baconbrix This is the break point

literally de-bugging Florida

@13ritta @appjsconf @swmansion Truly inspiring and awesome. The cheat sheet alone is pure gold.

That's a wrap on @Appjsconf 2026! Second time on stage and I keep coming back because this conference is just so good. The energy, the talks, the people... Huge shoutout to Paulina, @swmansion and the team. 🙌 #ReactNative

@Una Una, do you know if there is any way to align text flow inside such shapes? Will this come when shape-inside comes along as well?

I've been experimenting with an upcoming CSS feature called border-shape lately. It's really cool what you can do with it: lots of practical applications and it opens a lot of doors for non-rectangular UIs! Try it in Canary with experimental web platform features turned on, and read more here: una.im/border-shape

@jamonholmgren You have literally everything under control

In my game I have a lot of controller classes: GameController: runtime control MeController: has my character info, inputs, etc MissionController: handles the current mission LobbyController: multiplayer lobby stuff (etc) but I decided to just drop the *Controller suffix. It's easy to tell what these do based on context, and since these are singletons that are accessed as their class name, I can easily use them like this: ``` Game.pause() Me.character.promote(&"CPT") Mission.objective.position_2d Lobby.players().size() ``` No need to spam "Controller" everywhere.

@birch_js @hampus_s Please come and meet us at React Conf next week - we’ll do a talk on Day 2 - everything is live-streamed too.

@ChVanBoven @hampus_s 🤩 waiting to hear more!

Ship React Native with the iOS SDK, you cowards

@hampus_s @birch_js We had the opportunity to build a more optimized React Native embedded in the OS.

@birch_js I mean if this is a new React Native target for Linux then that's very interesting. They're not mentioning Android.

@tobimori @birch_js It is only new architecture and we are working on something more recent as well.

@birch_js i haven't dug deep but i heard they're shipping RN 0.72 so isn't it like a years old version? is it still old arch?

@aarongrider @cortinico We have built this for Linux based devices (Echo and Fire TV) right now.

@cortinico More platforms should do this. Do you know if this is targeting Android or a more base Linux variant?

This is HUGE news! Amazon just shipped Vega OS, their Linux-based operating system with React Native built-in! Like they're shipping libreactnative.so INSIDE the device, so you get smaller app size for each app and 1st class support for React Native development

@tmikov Will gladly send a few Fire TV devices too 😀

Meta just got me and the rest of the team great Windows laptops, to ensure that Static Hermes has first class Windows support! Damn, this laptop is better than my personal gaming PC, so I am quite excited about doing some Windows work! Will further unblock n-api.

@jamonholmgren @grabbou @mrousavy You can’t drive a tractor in Vienna.

this is NOT react native

@mrousavy @swmansion 👀

@swmansion this one's gonna be exciting!

Something's coming. This week. 🐎

@sebastienlorber Cool. Maybe use NotebookLM and you have a podcast about all this 😉

Wish me good luck 😄 Have to format/comment 4 sections like this for tomorrow's email

@tmikov Definitely agreed, have a look at an initial contribution to remedy this issue - github.com/facebook/herme… - we should extend this to the rest of API surface.

The Problem of Intl in Hermes We have known for some time that the Hermes implementation of Intl has flaws that are basically unfixable with the current approach which relies on different platform-specific iOS/Android APIs. Unfortunately these platform APIs are simply inadequate for implementing Intl. You can read some more details here: github.com/facebook/herme…. To make matters worse, nobody on our team is an Intl expert. Intl is a wide and complicated area that has very little in common with compilers, interpreters and VMs, which is where our expertise lies. Finally, Meta does not use Intl internally, which makes it very difficult for the Hermes team in practice. It is hard to develop and support something that we don't use (or even understand well). As a result of all of this, our implementation of Intl has stagnated. We have fixed some bugs and gotten some improvements in PRs, but as a whole it hasn't been improving much. So, I am wondering: would it be feasible to ship a built-in JS polyfill based on Intl.js or FormatJS instead? Do either of these provide sufficient functionality? If performance is not great, it certainly could be improved by adding type annotations and compiling the polyfill to native. It seems to me that a polyfill written in JS would be much easier to maintain and improve in the future. Of course if we do ship it, it would no longer technically be a "polyfill"...

@jwt0625 @rsms Hieroglyph sockets?

This repo/app makes animated “QR code” to transfer data at ~100 kB/s without using any RF signal. It uses 16 symbols * 4 colors, and 12400 tiles per frame to get 7.5 kB (+some error correction bytes) per frame. It has a beta mode thats > 1 Mbps and pbb could still be much faster.

@mrousavy @terrysahaidak 👏🏻 Are you using NAPI into Hermes?

NitroModules are 36x as fast as TurboModules - 𝗶𝗻 𝘁𝗵𝗶𝘀 𝘀𝗽𝗲𝗰𝗶𝗳𝗶𝗰 𝗯𝗲𝗻𝗰𝗵𝗺𝗮𝗿𝗸 (‼️) I'm saying "this specific benchmark" explicitly because there's a few things to keep in mind: 1. This is an isolated benchmark. Actual performance may vary. 2. One of the fundamental differences is that this uses zero-overhead Swift function calls. The Objective-C call uses message dispatches, and creates NSNumber* instances - the way I see it, this is the only way on ObjC TurboModules right now. It's fast, but not as fast as calling Swift directly. 3. I am not saying TurboModules are slow. They are insanely fast (nice work meta!). But by applying a ton of optimization strategies and caching tactics in JSI we can build even faster modules. NitroModules will soon be available for everyone to use, we'll start using them already for our libraries - I think they're quite cool :)
