M4v3R··on Prevent cognitive debt by manually retyping LLM-generated code
> Don’t good generals know how everyone else in their army does their jobs?

They most certainly do, but on a mid-higher level. They don't probably know every single motion and definitely lack hands-on experience. But they know enough to be able to manage them efficiently.

M4v3R··on Codex Security
Same thing happened to me. The partial output did contain some useful signal but I was disappointed to see it didn’t finish.
M4v3R··on Show HN: Infinite Jigsaw Game
I love it so much, it felt really good when I placed my first piece :). There are some technical issues, the UI and controls could be better, but it definitely was fun, and that's what really matters!
M4v3R··on Quake in 13 Kilobytes (2021)
Not sure if this is what you were thinking about, but .kkrieger was 96 kB and looked very impressive when it was released: https://www.pouet.net/prod.php?which=12036
M4v3R··on Google hallucinated that I am sponsored by Ground News
Never trust Google AI summaries, it hallucinates like crazy. I've recently googled my business name a few times on different machines and each one had at least one factual error, and what's worse - the errors were different for each run. Another time I wanted to know how to do something in Notion, and Google hallucinated a feature that does not exist, listing exact steps on how to enable it.

Try it - google your name, name of your company or "how to do X in software Y" and you'll see for yourself.

M4v3R··on OpenCV 5 Is Here: The Biggest Leap in Years for Computer Vision
The diagrams were generated with Nano Banana Pro (most probably, or alternatively with ChatGPT Image 2), if you look closely in high contrast areas you'll see artifacts in the background that give it away.

I personally don't mind AI generated content when it's properly reviewed, but unfortunately more often than not the author just glances at the result and decides it's good enough.

Example: https://opencv.org/wp-content/uploads/2026/06/image-1.jpeg

I'm not knowledgable enough to determine whether this diagram is 100% accurate, but some things look off - the arrows in the bottom left seem superficial, some arrows are connected in weird ways, the mini diagram in AttentionLayer block doesn't look right (it has two Softmax icons and one MatMul icon, while the "before" diagram is the opposite).

M4v3R··on Show HN: Hallucinate – Massively Multiplayer Online Rave
Fun idea! I was surprised that it loaded on mobile and UI was kinda reasonable but I could tap any buttons to move or do anything. I’ll look into sending a PR for fixing that.
M4v3R··on Deepfakes Tore a High School Apart
This kind of behavior should be met with swift and strong reaction from both the school authorities and the law enforcement. Kids responsible should be put on trial and face serious consequences including jail time for most egregious cases. Let the news cover it nationwide. "This is what will happen if you even think about creating and circulating nude pics of anyone" should be the message sent. This is the only way to prevent this behavior - not more censorship, not technical solutions
M4v3R··on Reverse engineering Gemini's SynthID detection
SynthID is visible in some generations (areas with a lot of edges, or text), I wonder if this would make them look better.
M4v3R··on Autoresearch on an old research idea
> What’s the point of adding features that are inscrutable?

You are assuming that the additional speed comes at a cost of codebase comprehension. For me it's not the case - I never push generated code I don't fully understand. It does take time, sure, but it still takes me much less time to write a spec, execute with AI and then review than write the thing myself.

M4v3R··on Show HN: I took back Video.js after 16 years and we rewrote it to be 88% smaller
Sibling comment didn't elaborate, but I think they might be onto something.

It happened to me personally - LLMs and agentic coding tools enabled me to pick up old side projects and actually finish them. Some of these projects were in the drawer for years, and when Sonnet 4 released I gave them another try and got up to speed really quickly. I suspect this happened to many developers.

M4v3R··on Autoresearch on an old research idea
> I find LLMs useful in regurgitating one-liners

This was the case for me a year ago. Now Claude or Codex are routinely delivering finished & tested complete features in my projects. I move much, much faster than before and I don’t have an elaborate setup - just a single CLAUDE.md file with some basic information about the project and that’s it.

M4v3R··on Autoresearch on an old research idea
Even if your tests take a long time, you can always (if hardware permits) run multiple tests in parallel. This would enable you to explore many approaches at the same time.
M4v3R··on Cursor's latest “browser experiment” implied success without evidence
Upon deeper inspection? Someone checked the Cargo file and proclaimed it was just Servo and QuickJS glued together without actually bothering to look if these dependencies are even being used.

In reality while project does indeed have Servo in its dependencies it only uses it for HTML tokenization, CSS selector matching and some low level structures. Javascript parsing and execution, DOM implementation & Layout engine was written from scratch with only one exception - Flexbox and Grid layouts are implemented using Taffy - a Rust layout library.

So while “from scratch” is debatable it is still immensely impressive to be that AI was able to produce something that even just “kinda works” at this scale.

M4v3R··on Cursor's latest “browser experiment” implied success without evidence
It’s not just a wrapper for Servo, the linked poster just checked the dependencies in the Cargo file and proclaimed that without checking anything further.

In reality this project does indeed implement a functioning custom JS Engine, Layout engine, painting etc. It does borrow the CSS selectors package from Servo but that’s about it.

M4v3R··on Shai-Hulud compromised a dev machine and raided GitHub org access: a post-mortem
Well pnpm does it by default for quite some time. It’s annoying, yes, but I take a little annoyance if it means I’m more secure.
M4v3R··on I failed to recreate the 1996 Space Jam website with Claude
Please reach out to your nearest government official to tell them what do you think about the Imgur not working in your country.
M4v3R··on Anthropic acquires Bun
Nothing I found says anything about Zig folks being inherently against AI. It just looks like they don’t want to deal with “AI Slop” in contributions to their project, which is very understandable.
M4v3R··on Apple Releases Open Weights Video Model
These are ~2 years behind state of the art from the looks of it. Still cool that they're releasing anything that's open for researchers to play with, but it's nothing groundbreaking.
M4v3R··on SmartTube Compromised
Is $14 dollars for ad-free, unlimited access to literally billions of videos really a steep price? Personally if I were to get rid of all but one of my media subscriptions I would stick with this one, since it's got everything - entertainment, education, inspiration, you name it.
M4v3R··on Nano Banana Pro
It's only a matter of time this will be fixed, also there probably already are custom LoRAs that can remove jpeg artifacts. So it's not a matter of if, only when.
M4v3R··on Checkout.com hacked, refuses ransom payment, donates to security labs
Words are cheap, but "We are sorry." is a surprisingly rare thing for a company to say (they will usually sugarcoat it, shift blame, add qualifiers, use weasel words, etc.), so it's refreshing to hear that.
M4v3R··on Vibe Code Warning – A personal casestudy
Have you tried Composer 1 from Cursor? It enables a totally different way of AI coding - instead of giving the LLM a long prompt and waiting minutes for it to finish, you give it a shorter prompt to just write one small thing and it finishes in seconds. There’s no interruption, you stay in the flow, and in control of what you’re building.
M4v3R··on Samsung Family Hub for 2025 Update Elevates the Smart Home Ecosystem
It is better, but I hated how some time ago they started showing trailers at the start of a show, with no option to turn this off. It’s a small thing but it’s super annoying, if I want to check out what’s new I will do it myself, thank you very much.

To be honest this whole article feels like it was AI generated. And em-dashes being used everywhere doesn’t help to shake off this feeling.

  when ({ status: s if s >= 500 }) -> throw new Error(’Server Error’)
Is it only me or this doesn’t look like JavaScript anymore?
M4v3R··on Claude outage
I'm sure some people did, by I personally use them every day - for coding tasks, for language translation, for research, current events (Grok is really good at this thanks to being connected to the X real-time data), for day-to-day questions (like my daughter asking me what's that Pokemon called) and so on.

I think you meant "until 1989"

M4v3R··on Improved Gemini 2.5 Flash and Flash-Lite
It was both efficiency and knowledge/reasoning update. GPT-5 excels at coding, it solves tasks the previous versions just could not do.
M4v3R··on Improved Gemini 2.5 Flash and Flash-Lite
It’s actually not. Most of the time if you ask it about a contentious political issue it will either give you a balanced view or a left-leaning one. Try it and see for yourself.
