What if your #ReactNative app could start fetching data already before the JS bundle starts running? 🤔
We migrated @expensify's app to 𝚛𝚎𝚊𝚌𝚝-𝚗𝚊𝚝𝚒𝚟𝚎-𝚗𝚒𝚝𝚛𝚘-𝚏𝚎𝚝𝚌𝚑 and moved its critical startup request ahead of JS - the result: Up to 950ms faster TTI! ⚡️
Across all daily active users, this saves more than 21 hours a day of loading time! 😎

@dmytro__petruk Even u can create your own state management library.

All modern state management libraries use the `useSyncExternalStore` hook under the hood.

A $6 SERVER REPLACED THE GUY WITH A CLIPBOARD COUNTING EVERYONE WHO WALKS IN - THE STORE PAYS $1,800 A MONTH FOR IT

00:02 no clipboard. no turnstile. no security desk. just a webcam and a line drawn across the frame.

the model boxes every person, gives them one id, and the second they cross the line it ticks: in or out. live, on screen.

the stack: yolo11 detects → bytetrack holds the id → a counter logs in/out to csv → a dashboard shows the number 24/7
the store doesn't pay for the code. it pays for one number: how many walked in today. that number used to need a human on a stool.

$47 a month to run - a $6 server, free models, a $12 - a - year domain. one client at $1,800 covers it 38 times over.

$47 in tools → 6 doorways → $11,000 a month in invoices, same month. no staff, no hardware box, no six-month build.

the uncomfortable part isn't that a camera can count. it's that every shop on your street still pays a person to do it, and almost nobody has offered them the $6 version.

save this and wire up one local doorway before someone else does.

No piensan responder que hicieron mal uso de nuestros datos? @ATTMx @ATT

Por que es causa de recesión de contrato sin penalización para las 41 millones de cuentas que registraron sin autorización 🤷🏾‍♂️

[David Quintero @DavidChuck01]

Se supone que esto debíamos hacerlo nosotros, no @ATTMx ?
Supongo que el siguiente paso será cancelar mi línea 🤷🏾‍♂️.
En ningún momento autoricé la vinculación con mi CURP.

@micka_design @shadcn Why does React have so many beautiful libraries? 😭
I worked with React for 3 years, but when I tried Angular, I decided not to come back. Now these libraries are making me consider going back 😭

[Micka @micka_design]

Now you can compare @shadcn components side by side with Fluid Functionalism components.

@almarag @powerhdeleon Y adivina a quienes contratarán para montar esos servidores y a quienes tendrán que mantener contratados para que esos servidores no se caigan, ah y también a quienes deberán mantener para revisar el código generado. 🤣
