Reminds me of this story from Windows land by Bruce Dawson (and similar on his blog):

63 Cores Blocked by Seven Instructions: https://randomascii.wordpress.com/2019/10/20/63-cores-blocke...

Looks like Linux isn't immune to these types of problems.

I have problems reconciling this story with the Amazon one from few days ago. If we take both for truth doesn't that basically imply Amazon researchers got scared by the ‘Fix this code’ prompt first and then spooked the feds? Shouldn't we make fun of those researchers first? I don't know. I feel there lies a lie somewhere in the open.

Agentic engineering? Vibe coding? That is so yesterday. Chain-of-thought flow is where it is at now. You heard it here first folks. Early examples of such phenomena include Rube Goldberg machines

Not really convinced by the first graph (and following too). According to it on a 10 year old project developers only manage to spend 10% of their available time adding features because rest is consumed by maintenance? By 10 year landmark I would expect most of software to be mature, with less new features needed and most known bugs fixed.

Got it. Vibe coding is all about the end result, damned be the way we got there. So I assume agentic engineering must be the opposite here? Don't care what we will cook. If I get a calculator while asking for integrator that is the true agentic engineering.

Caring about what? I could slap an application and say I vibe coded it or I could equally claim I agentically engineered it. No one could tell the difference(if there is any) without seeing the code. The only thing you could say I used an LLM. And that is what is happening. Most of the code that is "engineered" we don't get to see. So who know what is really going on there and what is the actual result?

> my disturbing realization that vibe coding and agentic engineering have started to converge in my own work.

>I firmly staked out my belief that “vibe coding” is a very different beast from responsible use of AI to write code, which I’ve since started to call agentic engineering

Disturbing? Really? I admit I don't do agentic and am going only by vibes, but for me agentic engineering is basically vibe coding in a automated loop with some ornamentals. They both stem from the same LLM root and positioning them as significantly different is weird and unconvincing to me. There may be a merit to this article (I gave up after few sentences), but I reject this specific premise.

I don't have a problem with AI assistance either, but this undermines the point the article is making. For me it is like a priest preaching gay sex is wrong and then being caught in bed with a male prostitute (snorting cocaine optional). Leaves bad taste in the mouth.

He writes 2,253 candidates and 2,069 were disqualified. 184 were qualified, so 1 in 12 was considered competent.

Asking ChatGPT about safety of someone traveling instead of asking that person is the nerdy thing to do. Somehow a hairstylist doesn't invoke image of a nerd in me. That is why I find this story implausible.

Agreed. Lead main source in nature is galena, which is relatively nontoxic. It rarely occurs in metallic form.

The fire started on 26th September and news about it reached HN only now. I think this is telling how disruptive for South Korea daily life this accident really was.

New comment by rotis in "Just let me select text"

rotis — Wed, 24 Sep 2025 20:44:54 +0000

Reminds me of one of the stupidest hacks I discovered (In my mind). In one of my previous companies we had many similar Lotus Notes databases and one of them didn't allow to copy text from it. You could paste, I'm sure. You could select the text. But not copy. Turns out you could DRAG the selected text to other window. This copied the text over. So being able to highlight a text may mean you can indeed copy it ;)

I'm sceptical a layperson will understand or care what it means that their data will be used in training. If you are concerned about such things this heavily implies you don't want to share your data. Just don't agree to the terms and move on.

Exactly. This is a basic optimization technique and all the dinosaur era databases should have that. But if you build a new database product you have to implement these techniques from scratch. There is no way you shortcut that. Reminds me about CockroachDB and them building a query optimizer[1]. They started with rule based one and then switched to cost based. Feature that older databases already had.

Everything else aside moving to R and Python to escape the USA hegemony means you are still dependend on Python Software Foundation and R Fundation. First is American. Second is based in Vienna, Austria yet still has big American presence among its members. So you end up still dependending on USA. Same with most free and open source. Even if its authors may appear to be European, they may turn out to be Americans (Linus Torvalds) or work for US company anyway (Guido van Rossum)
