Software guy. DevOps, productivity, and AI.

Intuition. That's the one big thing people building with AI are building that you can't get from watching from the sidelines. It's totally different to know how to use a tool intuitively, than knowing by having read a manual.

Build with AI, get a feel for it.

Introducing SubQ - a major breakthrough in LLM intelligence.

It is the first model built on a fully sub-quadratic sparse-attention architecture (SSA),

And the first frontier model with a 12 million token context window which is:

- 52x faster than FlashAttention at 1MM tokens
- Less than 5% the cost of Opus

Transformer-based LLMs waste compute by processing every possible relationship between words (standard attention).

Only a small fraction actually matter.

@subquadratic finds and focuses only on the ones that do.

That's nearly 1,000x less compute and a new way for LLMs to scale.

We are seeing that AI doesn’t necessarily provide a team-level productivity boost, even though individuals experience one. (See article for references) It should already be clear: writing code was never actually the bottleneck. https://t.co/iOJ0aP45k1

@simonbrown Did 4GL have the traction AI assisted coding has? Honest question (I don’t know). It may die, and we’ll be back where we were. Doesn’t look likely from what I’ve seen, though.

[Arien Kock @ArenCawk]

@simonbrown I read that a lot too. It’s slightly tangential, but it think there is some truth to comparing it to 3GL vs 2GL. Low(er) level coding doesn’t disappear, but the area it’s used in shrinks.

[Arien Kock @ArenCawk]

@simonbrown You’re right that if this was our main thing, it would get tedious. But I doubt it would dominate. There are parts of my job right now that I don’t like, I bet the future will be the same but different.

@A1_2026 All this because she rightfully denied a loan to an old lady. Just doing her job.

The smart enthusiastic team-player. Hiring was never or never should have been about knowing vs not-knowing.

In AI era, who gets selected? 👇

Candidate 1 :

- Knows every syntax
- Knows all theory
- Course & tutorial heavy
- 3+ certificates

Candidate 2 :

- Knows where to find the syntax
- Less theory but know where to read them
- Ships real projects (not just tutorials)
- Learns from YouTube, builds in public

Who would you hire?

It’s so hard to make some models write a failing test! They’re obsessed with making tests pass.

Your daily reminder that you are so early to AI.

- 84% have never meaningfully touched it
- 16% use a free chatbot occasionally
- 0.3% pay $20/month
- 0.04% use a coding scaffolding
- 0.01% are just like you

You're building orchestrated agents, running models at 2 am, buying hardware, and compounding your advantage every single day.

Meanwhile, 99.9% of people are laughing at Mac mini buyers, OpenClaw users, and home GPU nerds.

If you're part of the 0.01%, you are part of the collective building the infrastructure everyone else will depend on.

The gap is accelerating. Lock in.

@elonmusk Social safety nets are a good way to deal with a lot of things. Fair taxation is a foundation for a fair society.

[Arien Kock @ArenCawk]

Getting sponsored (or taking a loan) to learn a skill will never be a bad idea. But choosing which skill is becoming harder.

Software design (architecture) is as relevant as ever and has shown to be an essential skill whether it’s people writing code or AI.

[Suhas @zuess05]

Genuine question.

If Claude can now build production-ready apps in a few hours...

Why are 18-year-olds still taking out $100k in student loans for a Computer Science degree?

What exactly are they learning?

[Arien Kock @ArenCawk]

I feel like memory is overrated as a general requirement. I have updatable preferences for my calendar scripts, but overall I want my assistants to forget as much as possible.

[Arien Kock @ArenCawk]

PREDICTION: cheap shared PHP hosting is going to make a comeback. When the languages don't matter, LAMP stacks starts to look very good.

[Arien Kock @ArenCawk]

Was it really that easy? FYI I didn’t ask it to do it.

[Arien Kock @ArenCawk]

@MatthewBerman I feel the same. Spreading awareness isn’t much. But it’s something…

[Arien Kock @ArenCawk]

@simonw Double the token generation throughput. I might not know much about tweaking for performance, but out of the box 2x is great.

[Arien Kock @ArenCawk]

What are people’s experiences with Gemma 4 as a main brain?

[Arien Kock @ArenCawk]

@SNagarani1419 To different effect IMO. A candidate with a good idea & great execution would be impressive.

[Arien Kock @ArenCawk]

@lucas_montano Beats beng micromanaged by a human. Umm… I think
