Postgres 18 turns data checksums on by default at initdb.

pg_upgrade needs both clusters on the same setting, so a pre-18 one won't upgrade into a default 18. Either pg_checksums with downtime, or initdb the new one --no-data-checksums.

The easy path opts you back out of it.

The IETF is rewriting DKIM. Draft 6 of the DKIM2 spec went up 28 August.

One signature becomes a chain of custody. Every hop signs, and anything that changes the message publishes what it changed and a new hash.

Which makes ARC dead weight. Forwarding stops being an edge case.

The Play Store target API deadline was 31 August. Extensions run out 1 November.

API 36, new apps and updates both. Miss it and nothing gets rejected, your app just stops being visible on any OS newer than what you target.

Going invisible is worse. Nobody emails you about it.

Flutter 3.47 made header: true a no-op on iOS and Android.

Still compiles, nobody catches it in review, the accessibility is just gone. headingLevel above 0 now maps to setHeading and UIAccessibilityTraitHeader.

A breaking change that doesn't break the build is the worst kind.

Postgres 18 quietly changed what GENERATED ALWAYS AS means.

Write it with no keyword and you get a VIRTUAL column now. Computed on read, no storage. Before 18 the only kind that existed was STORED.

Same migration file, different table depending on which major ran it.

@elyxdesign Nice one. Been wanting to get away from Figma for gatekeeping MCP when it is just used as a diff/collab tool.

Went to sleep an woke up with an entirely new model type

When AGI happens, it’s going to be so fast

[Diogo Almeida @CompleteSkeptic]

After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI?

I’ve spent the last 2 years in stealth building a new way to train models (RLCD), and a new type of frontier AI model that we are releasing today: Jev

• 20-200x faster
• 40-400x cheaper (w/ output tokens free)
• Frontier composable intelligence optimized for decisions

AFAICT the shortest path to AI-based economic revolution

@theo Learn a second language or a secret language ha ha

@artem_zin Right tool for the job is the answer. Shopify/Notion does not determine the market vibes.

If so, people would have long moved long time when AirBnb switched.

@oliverbytes This is why you need a redeem code my friend. I read somewhere that this can flag as fraud but I guess it was in the Stripe world so not sure if it applies to IAP

@imadetheseworks At the end of the day, adopting the native design system make sense to an extent because that's the default but does not mean that it will continue to make sense that way.

With all these agentic capabilities, there is more to unlock on both performance and UX.

[ajmal 📱 @AjmalSalim]

@imadetheseworks I have been trying KMP + SwiftUI and it is close to best of both worlds. All logic is not duplicated but the UI experience is native.

Flutter still makes sense if they can keep with dart native.

The reason why Flutter seems outdated is because iOS just did a major revamp (1/2)

[ajmal 📱 @AjmalSalim]

@LeSovietOK @karrisaarinen @linear Wrong, Mac can actually background task compared to iOS.

Electron became standard so that they can ship cross platform without worrying about duplicating logic or release cadence.

[ajmal 📱 @AjmalSalim]

you can save a lot of tokens, if you can actually pick the right model for the right task.

@claudeai CC makes this extremely hard as it shares the same setting to other sessions.

I am pretty sure I don't need Fable for a rebase or commit message

[ajmal 📱 @AjmalSalim]

@coffman_r @GroundControl Yes, as of now. Apple/Google can change it.

If we can do SDUI now, we can render the whole app just like a website
