Intuitive Guide to Angles, Degrees and Radians

[If a 2-meter radius wheel turns 6 radians per second, scale by radius to get 6 × 2 = 12. If it turns 2000 degrees per second, the calculation becomes 2000/360 or 5 + 5/9 rotations per second, which plugs into the circumference equation 2 × π × r as 2 × π × (5 + 5/9)…]

[Degrees are arbitrarily based on the sun (365 days ~ 360 degrees) and use the observer’s perspective. Radians use the mover's perspective.]

A taxonomy of ATmosphere applications

['Symbionts' use domain expertise to fill Bluesky feature gaps. Their survival relies on Bluesky growing without competing.]

['Offshoots' leverage Bluesky's userbase to construct their own separate communities.] Their permanence will come from their unique services — Blacksky Cash, Eurosky’s jurisdictional arbitrage, Cartridge’s single-minded focus on gaming. They get to play a positive variant of the old Microsoft playbook: Embrace, Extend, Escape.

['Cuckoos' create paid services on top of ATproto's shared architecture. They survive by leveraging the ecosystem without appearing a threat, and also by non-competition from Bluesky.]

Fresh bread time. No kneed, 14 hour ferment.

Before bed: add 2x 500ml jugs of bread flour, 1 jug of warm water, quarter teaspoon of dried yeast, 2 teaspoon of salt, 1 tablespoon of rapeseed oil or olive oil to a bowl. Mix together with the handle of a wooden spoon. Cover and let rise overnight [at room temperature].

The dough is quite sticky, wet your hands to handle it. pull the edges of the dough to the center a few times to stretch the gluten. Split the dough, put in loaf tins or shape. Leave to rise again [until the high point is near the top your tin, maybe around 2 hours depending on temperature]. Bake it in a hot [maybe 220º] oven for 40 mins.

OpenSourceAlternative.to

Replace proprietary software products with open source alternatives.

Dropping to log-level

God is very cruel. He only gives us data about the past.

[Use the simplest model with sparse data and complicated models with abundant data.]

[When things move quickly, a log helps us understand what happened and enables us to extract pattens without needing to determine the best structure in advance.]

Sounds like Stevie Wonder singing Brazilian Portuguese.

The case against conversational interfaces

We are significantly faster at receiving data (reading, listening) than sending it (writing, speaking). This is why we can listen to podcasts at 2x speed, but not record them at 2x speed.

[Roughly estimated: mobile typing ~30wpm; writing/typing ~60wpm; speaking ~150wpm; reading ~250wpm; listening ~270wpm; thinking ~1000–3000wpm.]

[Gestures and facial expressions compress data so we can trade specificity for speed.]

Rewilding Software Engineering

[Software gets built in economical and social environments that constatly change. What we call 'legacy' reflects an inability to adapt change or a lack of refactoring to match software to its new environment.]

[LLM error rate of ten percent (for example) is problematic when you don’t know which ten percent is wrong.]

Comprehension is not a nice to have. It is the scaffolding that makes safety, accountability, and learning possible

People like simple scalars, like KPIs regardless of whether they are useful or downright harmful. They have the one property that manager’s like … they are simple, because we are busy people.

I was a 10x engineer. Now I'm useless.

[There's no middle ground where you only decide to do crack on Mondays and Wednesdays.]

Let's talk about Trump, 200 billion dollars, and a promise....

[Running countries like a business means the shareholders (financial donors) are best served when the company (government) extracts as much as possible from consumers (you) while providing little in return.]

[All states are violent by their creation and maintenance because it's intrinsic to their nature.]

Criticizing your own tribe is how you win

It’s obvious to me that criticizing your own tribe is a winning strategy. I want my friends to do this, because it will help us win. I’m giving this away as “free advice” to my enemies too, because even if they win, it still creates a world that’s better for me.

Every redundant availability zone, every warm standby in a second region runs on physical servers drawing real power and real water from those same irreversible natural systems.

X Is a Power Problem, Not a Platform Problem

the functioning of the neo-royalty is such that other governments taking actions against X will be taken as an offensive action by the US regime, that will likely trigger extensive retaliation. No country seems to be willing to be the first one to move to take action and thus take the brunt of the counter-offense of the regime.
