lexandstuff··on The Real Luxuries In Life
I worked in a mattress factory for a while, doing the same repetitive task day in and out.

I remember feeling like the days passed painfully slowly, but the years flew by.

lexandstuff··on The safest job from AI may be writing
To the contrary: Twitter has the lowest content engagement rates out of any of the networks.
lexandstuff··on LinkedIn CringeBot 3000
Yep.

LinkedIn is pretty much the only social network out there where the average person has a shot at a little reach for their posts.

Even if it’s just past and present colleagues and various acquaintances, I actually have an audience of people who are sometimes interested in what I have to say. I can't say that for any other social network.

lexandstuff··on Stateless MCP has recaptured my interest
Yes, MCP is an API.

Previously, it was an API with a weird stateful standard; now it is essentially a bog-standard stateless JSON-RPC API with conventions for tool discovery, long-running tasks and multi-round-trip requests

If you wrote your own JSON-RPC API for an LLM, you would probably eventually end up with something that looks very much like the standard they're describing.

lexandstuff··on Kimi K3 Is Competitive with Fable; Kimi K3 and Fable Is SoTA
It should be SotA.
lexandstuff··on No-One Escapes the Permanent Underclass
Ilya Sutskever said in 2017, whilst building OpenAI:

> Within the next three years, robotics should be completely solved, AI should solve a long-standing unproven theorem, programming competitions should be won consistently by AIs, and there should be convincing chatbots.

There was a viral YouTube video from 2014 called Humans Need Not Apply [1], which made a very strong argument that mass unemployment was right around the corner.

I actually think people from the past would be surprised at how slow AI has progressed in the end. Although the domains where it's turned out to be most effective - code, images, videos, music, etc. - would probably surprise them.

lexandstuff··on Completing a computer science degree on Coursera
Thank you!
lexandstuff··on Shipping a laptop to a refugee camp in Uganda
I take your point - no doubt I approached this in a very naive way.

That said, we did collaborate on it - at the very least I needed to learn his address before sending.

Neither of us have ever sent or received a package in Uganda. It was a learning experience for both of us.

lexandstuff··on Shipping a laptop to a refugee camp in Uganda
~$200 doesn't go as far as you'd expect for good used laptop, even in Uganda. We did look into our options.

However, there's definitely a sunk cost aspect to the operation. After the first failure to send it through Australia Post, I became determined that Django was going to have that MacBook.

lexandstuff··on "People who don't use AI will be left behind"
I have a feeling that a big risk of using AI all the time is that our own neurological capacity starts to dwindle.

Just as many people leading sedentary lifestyles have to make a deliberate effort to exercise, because inactivity is really bad for our bodies, I think we're going to realise that a similar process is necessary for our minds.

You really want to be spending a bit of time every day operating at your cognitive limits - trying to fully engage your System 2 - if you want to avoid brain atrophy. Coding used to kind of give you this exercise for free, but you can go really far with just your System 1 nowadays - literally get things done while scrolling Reddit.

I'm trying to allocate 30-60 minutes a day to doing something difficult, like writing code by hand for an unfamiliar problem or reading and summarising difficult papers without AI.

lexandstuff··on At long last, InfoWars is ours
Of course Hacker News would be full of Greggheads.
lexandstuff··on Ask HN: Who is using OpenClaw?
Yeah, not locked in with Obsidian.

I just use it as a Markdown viewer/editor, and it handles updating links across notes when a file is renamed. There are some handy conventions that Obsidian encourages, like Daily Notes, templates and linking across notes, enough to call it an Obsidian project, but yeah - it's just markdown. I don't even use the [[Wiki-links]] style that it uses by default.

lexandstuff··on Ask HN: Who is using OpenClaw?
I already had the hierarchy from years of maintaining the notes, but for new things I do collaborate with the model on how best to structure stuff and get it to refactor when needed.
lexandstuff··on Ask HN: Who is using OpenClaw?
I recently switched to Codex using my ChatGPT Plus subscription, so only $20 a month or so. Before that, using Opus 4.5/6 it was like $100-150.

Opus was by far the best at the job, but Codex with GPT 5.4 is decent.

lexandstuff··on Ask HN: Who is using OpenClaw?
Wow. This is a really cool idea. I am using Obsidian for family history, but I never thought to let people chat with it and update it via OpenClaw.
lexandstuff··on Ask HN: Who is using OpenClaw?
I still use it and find it helpful.

My OpenClaw instance uses an Obsidian project as its memory. Mainly, it's just my main day-to-day LLM that I access via WhatsApp, but instead of the memory being locked away with a specific vendor, it's stored in version control that I can read and edit. That reason alone makes it compelling to me. When a better LLM comes along, I can just switch, and my memory and system prompts come with it.

However, I also use it for calorie/weight/workout tracking, to-do lists (bill, birthday, event reminders), and to support my various life admin tasks. I don't give it access to much at all, except a few skills that give it read-only access to some data.

Hasn't given me a 10x productivity boost or anything. It's just handy.

I wrote an article on it, if anyone is interested: https://notesbylex.com/openclaw-the-missing-piece-for-obsidi...

lexandstuff··on AI-assisted cognition endangers human development?
> I can't traverse as much land on foot as my ancestors did, but I can travel further by car/plane/etc

Which is partially how we found ourselves in the midst of an obesity epidemic.

lexandstuff··on Molotov cocktail is hurled at home of Sam Altman
I've found that most non-tech people are indifferent or, at worst, utterly bored by any mention of AI.

The tech people are the ones that have the strongest opinions one way or the other.

lexandstuff··on Who is Satoshi Nakamoto? My quest to unmask Bitcoin's creator
I had always assumed that all of them shared the pseudonym of Satoshi, along with Nick Szabo.

Back wrote the white paper with input from Hal and Nick Szabo. Sassaman did the coding work on the client. Sassaman had the keys to the Satoshi wallet, hence it never moving since his passing.

Since Satoshi is a collective, it means that each of them individually can claim, without lying, that they're not Satoshi.

That's my uninformed guess.

lexandstuff··on Grok 4.20 Beta
The thread is just a link to Grok. There's no information about the model or anything to discuss. If they release some information about it, maybe a benchmark or two, I'm sure there'll be more of a conversation.
lexandstuff··on Claude Composer
It has hit the mainstream imo. Most people are content with the amount of music already available.
lexandstuff··on Ask HN: Any real OpenClaw (Clawd Bot/Molt Bot) users? What's your experience?
I'm a real user. I've found all sorts of uses for it, from calorie/fitness tracking to birthdays and gifts. I love how well it integrates with an existing Obsidian vault. I wrote a blog post about it, if anyone is interested: https://notesbylex.com/openclaw-the-missing-piece-for-obsidi...
lexandstuff··on Ask HN: Any real OpenClaw (Clawd Bot/Molt Bot) users? What's your experience?
It's this but with a lot of handy features.
lexandstuff··on Project Genie: Experimenting with infinite, interactive worlds
The mass-poverty and climate changed ravaged world parts, I could definitely see.

lexandstuff··on Professional software developers don't vibe, they control
It's not complicated at all. You don't "manage agents". You just type your prompt into an terminal application that can update files, read your docs and run your tests.

As with every new tech there's a hell of a lot of noise (plugins, skills, hooks, MCP, LSP - to quote Kaparthy) but most of it can just be disregarded. No one is "behind" - it's all very easy to use.

lexandstuff··on Udio Bans Downloads after Settlement with Universal Music Group
Interesting to see so few comments about this.

This is the start of the end of generative AI music.

Without the entire music catalog, they are just not going to be able get the diversity and quality of outputs they once had, and the labels are always going to have their hands out wanting more.

Udio and Suno have demonstrated that okay-quality new music can be created by training on vast collections of pirated music, and, as expected, the music labels shut them down.

lexandstuff··on LLMs can get "brain rot"
It's a line from a banger Skrilla song, nothing more than that.
lexandstuff··on AWS multiple services outage in us-east-1
Yep. I don't think they ever fully recovered, but status page is still reporting a lot of issues.

Thankfully Slack is still holding up.
