@BelligerentLamb @vcoolish @grok Hey! Let me check what is happening on your side

[Evgenii Matsiuk @e_matsyuk]

I have no words to describe it. @elonmusk is building the future and doing unbelievable things. How is it possible? Amazing! Really proud to be part of this future.

Bye-bye Firebase Test Lab. We will remember you.
But what about users of FTL? Official replacement is so expensive. That’s why, welcome to Marathon Cloud folks 😊

[Anton Malinski @anton_malinskiy]

Firebase Test Lab shuts down Sept 30, 2027.

Its replacement, Google's Developer Device Platform, goes to $3.60/h per emulator and $12/h per iPhone in April 2027.

Marathon Cloud: $2/h Android, $3/h iOS, billed per second.

50 free device hours, no card

@ZachWarunek No tests - No Problems!

@fram3o @grok could you explain this scene, which film, why it is so popular now?

[Evgenii Matsiuk @e_matsyuk]

Let's split two issues.
The first issue from my understanding is that you are not able to send a post under 25.000 characters with Premium Account, right?
The second issue is a video uploading. I guess if you try to upload a single video without text then everything will be fine, right?

@Ultima_Lumina Let me check too

@iampgzp Finally! Love Notion but the mobile version was always full of pain. Very bad performance, no offline mode. It’s the best news today for me, thank you guys!

Hi X Android folks!

If you're on version 12.20+, you're now running the latest iteration of our new Android app. For context: for the last 8 months we were shipping two apps in a single binary, and that introduced some perf overhead. But shipping two apps in one was needed to make the switch to the new experience as smooth as possible for everyone.

With 12.20+ that overhead is gone. We ship a single app, built entirely on the new shiny kotlin + compose codebase.

This resulted in:

• 33% smaller app binary size
• 69% faster app startup
• Got rid of 3.15M lines of code from the OG app

What's next: we hear you on performance. It's our main focus right now - scroll smoothness, battery, networking and memory - and there's more coming.

Thanks for the patience and the feedback along the way - keep it coming!

[Evgenii Matsiuk @e_matsyuk]

@SebJohnsonUK @grok is that true?

Grok Bot is now available on Android.

We will miss you Mike!
It was wonderful to work with you. You are one of the best and strongest managers with whom I’ve worked or interacted. Pretty sure you’ve deserved good rest and relax! See you ❤️

[Mike @cambridgemike]

After 13 years, this is my last week at X. So proud to be a part of the team that builds this incredible platform. X is the only place in the world that gives everyone a voice in the global town square.

Behind the app is an insanely talented team of engineers and staff who work 24/7 to make it better. I couldn’t be more grateful to have gotten to work so closely with them. Especially the last few years building under pressure most companies will never know. From stabilizing core systems to rebuilding DMs and live-streaming, every day I learned something new from brilliant people. Thank you to everyone who helped me out along the way.

💙🖤
