[Edward Jiang @EdwardStarcraft]

@omooretweets @triumpharcade Appreciate the shoutout! If you’re a builder who cares about crafting beautiful experiences DMs are open!

[Edward Jiang @EdwardStarcraft]

@fedor @Dimillian I have a lot more thoughts since our last convo. I’ll email you

[Edward Jiang @EdwardStarcraft]

We’ve been dealing with this as well. Have some ideas for tooling that can improve iOS dev if anyone wants to jam!

[Thomas Ricouard @Dimillian]

The bottleneck for iOS dev is truly the CPU now.
It's hard to work on features in parallel and testing if the app is compiled locally.

[Edward Jiang @EdwardStarcraft]

@expo Yes! https://t.co/ky0bwKVXxn

[Edward Jiang @EdwardStarcraft]

@DaehyeonMun @expo @ReactNativeSkia We have some of the top apps in the App Store. Looking for ppl who care about design and craft. Let’s chat!

[Edward Jiang @EdwardStarcraft]

Most frustrating CAPTCHA I've ever seen

[Edward Jiang @EdwardStarcraft]

#1 all games on the App Store!

[Neall @neallseth]

I’m learning so much today

[Edward Jiang @EdwardStarcraft]

@chanian @zeeg It took 2 months for their sales team to answer a question about SSO. They’re prob just swamped. I’ve heard you can leverage moving this spend to AWS bedrock/GCP vertex for some discounts. The annoyance is that cost reporting is on a per project not per user basis with GCP

[Ian Chan @chanian]

Poker / solver friends:

I decided open source my base implementation of CFRM engine (and port it to Go).

My original implementation took me about a year. gpt-5.3-codex ripped through it in 3.5 minutes. wild world we're living in. codebase below

[batteries, and ui not included]

@WestonMizumoto @TheRyanFeldman I texted them a link!

[Edward Jiang @EdwardStarcraft]

@dillon_mulroy @dolevkle Considering an alternative to Graphite; you're heavily JJ over Sapling? Ryu seems cool but not sure how bleeding edge I want my team to be. Then again I haven't really tried ReviewStack but I really liked Phabricator

[Edward Jiang @EdwardStarcraft]

@chanian @HipMrBully Let me double check, sometimes it runs a limited Monte Carlo and sometimes it runs exhaustive if there are few enough combos. But I don’t remember the exact threshold

[Edward Jiang @EdwardStarcraft]

When you work as an effective team it doesn't feel like your individual contributions matter even though they do.

In tug-of-war the rope seems to move of its own accord but tell everyone it's bullshit work and your team will never win

[Chris Morlock @CDMorlock]

Here is my theory why this is video is viral: it represents the role we play in the western world as a de-proletarianized society; we are simply here to keep financial markets solvent. 80% of western economy is basically this. The appearance of "work". We make nothing.

[Edward Jiang @EdwardStarcraft]

Is it performative if a new hire wants to onboard on Christmas? Welcome the team, Weifeng!

[sudarshan @ItzSuds]

I’ve seen inside the fastest growing startups & somehow @triumpharcade is growing faster

No one has executed better in a harder space than @Jakebrooks

I truly thought consumer was uninvestable. Turns out it’s only an impossible nut to crack until the right team shows up 🚀🦄

[Edward Jiang @EdwardStarcraft]

Fantastic guide; I appreciate what Swift 6 is trying to do but honestly it’s gone off the rails with its approach to being concurrency safe

[Pedro Piñera @pepicrft]

Week off, so I dove into approachable Swift concurrency after years of postponing.

Thanks to @mattiem's impressive work + coding agents for real-world analogies, I built mental models and made: https://t.co/8AJRcHz0yS

Probably got things wrong, feedback welcome!

[Edward Jiang @EdwardStarcraft]

@psa2rpa Lower ETA, lower margin, faster travel time, higher trust among late adopters, more route availability

[Edward Jiang @EdwardStarcraft]

Waymo has hit a marketplace equilibrium in core markets so is focusing on horizontally scaling to more cities. To truly capture the market it needs something else.

[Stefan Schubert @StefanFSchubert]

Waymo has quickly captured more than 10% of the SF ride-sharing market
