sebastianconcpt··on OpenAI, the US government and Persona built an identity surveillance machine
Surprisingly close minded and selective read. That way you'll see black swans even in paradise (or the whatever utopialand of your choice).

Quite some time ago I said and now repeat:

Convenience is to humans, what bulb lights at night are to bugs.

sebastianconcpt··on SkillsBench: Benchmarking how well agent skills work across diverse tasks
Ok fair, thanks for explaining
sebastianconcpt··on SkillsBench: Benchmarking how well agent skills work across diverse tasks
I am the only one surprised about anyone's need for a study to conclude that?
sebastianconcpt··on Frontier AI agents violate ethical constraints 30–50% of time, pressured by KPIs
Mark these words: The chances of this being an unsolvable problem are as high as the chances to make all human ideologies agree on whatever detail in question demands an ethical decision.
sebastianconcpt··on Ask HN: What are you working on? (February 2026)
Nice. Sounds like will converge to QA as a Service

sebastianconcpt··on I miss thinking hard
> I am currently writing much more, and more complicated software than ever, yet I feel I am not growing as an engineer at all.

This sounds like approving bad/poor abstractions too prematurely and keep building on top of that.

What about the satisfaction that comes not with struggling but from the calmness of an elegant functional model that dynamically covers all the flows and all the edge cases you could (deep and slowly [1]) think about?

[1] maybe refining in different days, in the shower, after recovering breath in a hard set in a workout session, after a nap...

sebastianconcpt··on De-dollarization: Is the US dollar losing its dominance? (2025)
India pays one 1.4 GW nuclear power plant in yuan and they start talking about global de-dollarization as if people can't think in proportions anymore?
sebastianconcpt··on U.S. Emissions Jumped in 2025 as Coal Power Rebounded
The issue is never the issue. The issue is always The Revolution.
sebastianconcpt··on Apple picks Gemini to power Siri
Someone inside and up there neglected the "a bicycle for the mind" part of the vision.
sebastianconcpt··on Apple picks Gemini to power Siri
Pity they don't have their own thing at that level. They had a great start introducing Siri then totally missed the train.
sebastianconcpt··on U.S. Emissions Jumped in 2025 as Coal Power Rebounded
And how China compares its 2024 to 2025?
sebastianconcpt··on Zen-C: Write like a high-level language, run like C
But at that point why not Rust then?
sebastianconcpt··on Approachable Swift Concurrency
But how would you do what in Rust's Tokio is a `spawn_blocking` in Swift?
sebastianconcpt··on AI is forcing us to write good code
In Cursor you have Sandbox mode to deal with that issue?
sebastianconcpt··on AI is forcing us to write good code
I feel more like is forcing to write better engineering not just the code.

The disruption comes from the economics of cognitive labor, the synthetic assistants are making feasible things that before were unbearably cognitively costly so manually we invested all that energy into the code parts.

I've made this to leverage that:

sebastianconcpt··on AI agents are starting to eat SaaS
Isn't plenty of space of efficiency value in SaaS over AIs? And depending on the use-case and what the optimization is, also performance?
sebastianconcpt··on Apple has locked my Apple ID, and I have no recourse. A plea for help
Only depend on platforms as redundancy. Never as primary source.

Break that discipline and you are exposing yourself to this danger.

sebastianconcpt··on Microservices should form a polytree
The issue is that one of the services is the events hub for the rest to remain in loose coupling (observer pattern).

The criticality of Kafka or any event queue/streams is that all depend on it like fish on having the ocean there. But between fishes, they can stay acyclicly dependent.

sebastianconcpt··on Microservices should form a polytree
Okay yes, agree. This goes inline what I do and promote among teammates all the time "maintain one-way dependency discipline".

Tree or not, it will render you acyclic graphs.

sebastianconcpt··on If you're going to vibe code, why not do it in C?
> Why vibe code with a language that has human convenience and ergonomics in view?

Because you would not be able to audit the code if you don't (you'll be terribly slow to read and understand the inner flows correctly and that's if these aren't so bad that would do you some brain damage).

Dang, AI is pushing us all to become managers.

sebastianconcpt··on A series of vignettes from my childhood and early career
The reports about our death were greatly exaggerated.
sebastianconcpt··on Datacenters in space aren't going to work
Well we need like successful technological disruptions like in 7 dimensions before this can be scale and ROI positive.
sebastianconcpt··on Technical Deflation
Dang. I won't be able to sleep tonight
sebastianconcpt··on I converted a rotary phone into a meeting handset
The feeling of the hang up is so satisfying. An important piece of UX.
sebastianconcpt··on Over-regulation is doubling the cost
Just on bad rule could more than double the cost. Or even put your project completely out of any feasibility region
sebastianconcpt··on Boa: A standard-conforming embeddable JavaScript engine written in Rust
What's the use case?
sebastianconcpt··on Ruby and Its Neighbors: Smalltalk
Haahahah true! Well put.
sebastianconcpt··on WriterdeckOS
No autosaving. That's the wrong way to try to be minimalist.
