Building

[Peter Kyle @peterkyle]

The UK has a responsibility to create the conditions that businesses need to succeed. That's why we backed companies like Octopus’s Kraken, now valued at $8.6 billion.

Since 2025, The US has committed $10 billion in exchange for equity stakes in strategic companies. The EU has announced a €5 billion scale up fund which has the European Commission as a founding investor. If we don’t support companies of the future then we will continue to lose them.

Contrast the quote my experience: An Employer once had a supply issue with equipment supplier.

Opened a new bank account that allowed Apple Pay digital cards over email.

Created me a card. Sent it over. Transferred cash onto it, apologised profusely and asked if could go to Apple Store (during work hours so fine with me)

Nice to know when you’re working with serious people.

A new hire showed up Monday. No laptop. IT was "working on it."

Day 2: Still nothing.
Day 4: She resigned.

Adding to the chorus of Codex and GPT 5 evangelists.

Been stuck on gradually worsening Claude Code harness with painfully slow 4.7

Spent the evening with Codex native and 5.5 in Pi and everything’s productive and fast and predictable again.

Trying to enforce workflows in easily pollutable agent-context-windows drives me nuts as a concept.

There’s so many tools out there people don’t even bother setting up:

Types everywhere, oxlint with custom rules, oxfmt, Percy visual diffs with pixel maps, build a manual component design system, build a tested data-loading module with auth handled (tRPC), knip for dead code, Stryker for test testing, sonarcube for quality, axe-core, snyk, new relic, autocannon, lighthouse, Zod, typed db schemas with Prisma etc etc etc

Rabidly configure hooks that tell agents to fail if any of those deterministic checks fail.

Think of it as local continuous integration that blocks Agent code edits if they deviate slightly.

Go hard on deterministic CI, then bring in a powerful agent and give it preconfigured tools to execute - don’t let it invent the universe in every conversation.

[patagucci perf papi @kenwheeler]

agent driven workflows with a sprinkling of deterministic tools are a fools errand.

especially with subsidization fading, expect to see deterministic workflows with a sprinkling of agent nodes, doing what they’re actually good at.

It takes 5 minutes of right clicking on elements you don’t want in Obsidian to make it insanely minimal.

You still get all power features behind a command palette.

@obsdmd undefeated imo, especially with sync and headless CLI

[Tiago Forte @fortelabs]

Can anyone recommend a dead simple, easy to use notetaking app based on markdown files?

Obsidian is far too complicated for me. I'm looking for Apple Notes, but with markdown storage

[Jon Sherrard @jshez]

@nicbarkeragain Is the only route out open source codebases and big bounties?

[Jon Sherrard @jshez]

Your chat bot is dumb and a sycophant.

Mine is very smart and doesn’t pander in the slightest.

Is there a way to configure hooks to never send to auto mode? I have custom hooks that have pretty strong negative signals in permissionDecisionReadon but auto mode is always approving them instead of asking. I want a flag that says “even if auto-mode says yes - ask the user” or a flag to skip auto mode even if it’s on

@antirez Do consumers get stuck with Opus 4.x class and GPT 5.x class for years while Mythos patches all software behind the scenes?

[Jon Sherrard @jshez]

@waitbutwhy Analogous to British and American politicians and the 4th estate. Media shames and criticise relentlessly -> Parties and electorate select for shamelessness, and insulation to criticism irrespective of their talent.

[Jon Sherrard @jshez]

So Mythos has to fix every bug on the internet, every package, every operating system, and every browser before it can be released.

Does that mean the general public is stuck on Opus 4.6 and GPT 5.4 capability LLMs for a few years?

[Jon Sherrard @jshez]

@aleks_todo @steipete @DannyIO @danshipper oh shit, medium thinking 🚀📈 it's working!

[Jon Sherrard @jshez]

@steipete @aleks_todo @DannyIO @danshipper Update to dev channel worked for me, but gpt-5.4 still regularly says "I've started that task", instead of starting->waiting for result-> replying

[Jon Sherrard @jshez]

Yesterday I used @perplexity_ai Comet to plan some simple meals and snacks for the week, and then order it all at Carrefour via Rappi.

Amazing how the future is here and we're so blasé about it.

And as the old adage goes, it's the worst it'll ever be.

[Jon Sherrard @jshez]

@bcherny @MattLeonard1616 Also reporting a not working but also the value does not match the value of my plan

[NASA Earth @NASAEarth]

That's us! 🌍

The Artemis II crew captured beautiful, high-resolution images of our home planet during their journey to the Moon. As @Astro_Christina put it: "You guys look great."

[Jon Sherrard @jshez]

Well the Gemma e4b is pretty amazing on a 24GB Macbook Air M2
