rubslopes··on Previewing GPT‑5.6 Sol: a next-generation model
Wow. Sci-fi stuff!
rubslopes··on The brain was not designed for this much bad news
Same here, but I live in a developing country. I usually switch to international news (or tech news, or no news at all) because local news is mostly about murders and other terrible things. I have family in Portugal, and when I visited, I remember the local news being mostly about pastries and folklore events. I watched TV every day while I was there.
rubslopes··on Google Chrome update will close the door on ad blockers
I've been using Zen since almost the beginning of the project. I'm pretty happy with it! Great QOL features, and being Firefox, I have perfect ad block and syncs nicely with Firefox for Android.
rubslopes··on Ask HN: Which cheap Chinese LLM are you using?
I was going back and forth between kimi k2.6 and deepseek v4 pro, but it's been 2 weeks that I've been using deepseek alone. It's very good and very cheap, I pay the opencode go $10 subscription and don't have to worry about quotas.
rubslopes··on Rio 3.5 Open 397B – from Rio de Janeiro's city government
I've met some of the IT team of the city government of Rio de Janeiro years ago, before LLMs were a thing. They were already doing state-of-the-art data science projects. Glad to see how far they've gone.
rubslopes··on Show HN: Verso – A $14.99 Mac word processor with no subscription
If it's really fully compatible with docx files, I'm very interested in this. No matter the advances Apple makes with the M chips, Office apps are always slow to open. Not to mention the obligatory background services.
rubslopes··on A greyscale iPhone setup that works in everyday life
Samsung routines can do this.
rubslopes··on MCP is dead?
MCP allows you to easily separate API requests from their access tokens, so that the LLM only has access to the requests part. Giving an LLM CLI access removes all boundaries, anything goes.

EDIT: to add an example: I have a personal claw agent that I only use CLI, I don't care. But I'm also building an agent inside a company product, and there we use MCP all the way.

rubslopes··on Task Paralysis and AI
I feel lucky to have been promoted to a management position recently, just as I was starting to feel less excited about dev work because of AI. I still enjoy building systems, but I have to admit that the loss of challenge made the work much less enjoyable for me.

Now I have a team of interns to mentor. They're sharp and use AI constantly, so my guidance is less about code and more about UI/UX, understanding what the client actually wants, good work practices, well-documented tickets, thorough reviews, and so on. Thankfully, I like this work, it has been very rewarding.

rubslopes··on Using Claude Code: The unreasonable effectiveness of HTML
Yes, I do think it is.

HTML made by Claude will, by default, be "sleek, modern", with colorful tables, cards, maybe Tailwind for styling. And, of course it will, if you wanted a barebones HTML, you would just have asked for markdown!

So the LLM decided to present some content using 4 cards, and you now want to add new itens. You can't just add new lines of text: you need to copy the whole HTML of the cards. But the LLM used different colors for each card, so now you have the first cards with varying colors and the new cards all the same color as the last card. Now you have to think about colors... etc etc

rubslopes··on I'm scared about biological computing
> Although it will make up for a "wow, we really did it" moment, it will be met with hollowness

I hadn't heard this view before, but it does make sense...

rubslopes··on From Supabase to Clerk to Better Auth
People are afraid to touch dangerous things, like passwords and payment systems. Depending on their skill level, they should indeed be afraid.
rubslopes··on I'm scared about biological computing
Correct.

Still, the day we manage to run a full LLM on biological neurons, even if using conventional code under the hood, will be a very interesting day for consciousness discussions.

rubslopes··on Why TUIs Are Back
I thought that that was the case for me, but then I tried using Claude Code through the desktop app last week and it was so bad. Slow, glitchy... I went back to the TUI in no time.
rubslopes··on Kimi K2.6 just beat Claude, GPT-5.5, and Gemini in a coding challenge
I don't think the real-world evidence supports your argument... OpenAI and Anthropic have all of those advantages today, and Chinese models are reaching the same level. Clearly, the Chinese labs are doing something very right that is not directly related to infinite money.
rubslopes··on Becoming a father shrinks your cerebrum (2022)
Happy birthday to the youngest and oldest!
rubslopes··on Claude Code refuses requests or charges extra if your commits mention "OpenClaw"
I think OP means standardized benchmarks.
rubslopes··on Claude Code refuses requests or charges extra if your commits mention "OpenClaw"
A fellow user replied below, but it refers to the software that uses the LLM (Claude Code, Opencode, pi.dev, etc.).

---

Funny you mention that, because I started noticing the word 'harness' being used everywhere about a month ago, even though I hadn’t seen it before (in this context). As I don’t trust my memory, I assumed I had just been overlooking it and added it to my vocabulary. However, a Google Trends search does show increased usage since the end of March: https://trends.google.com.br/trends/explore?date=today%203-m...

rubslopes··on Claude Code refuses requests or charges extra if your commits mention "OpenClaw"
Harness: opencode

Subscription: opencode go

I also use a claw agent[1] via Telegram, which uses pi.dev under the hood with my opencode go subscription.

[1] I forked one of those Claw projects (bareclaw) and made many changes to it.

rubslopes··on Claude Code refuses requests or charges extra if your commits mention "OpenClaw"
April has been a crazy month for open weights models. I've been using Claude Code for work and Kimi 2.6 for personal projects and Kimi has been very good. Glm-5.1 is also great. Qwen, Mimo and Deepseek I need to test some more, but they all have been producing good results. I have the impression that they are all are at the same level, or close to, Sonnet 4.6.
rubslopes··on Localsend: An open-source cross-platform alternative to AirDrop
Thanks for the tip. Just tried it and it worked great between MacOS and Android.
rubslopes··on Is my blue your blue?
90% here, and it makes sense. I'm very picky about saying something is blue!
rubslopes··on Plain text has been around for decades and it’s here to stay
I was confused about why your comment was being downvoted; it sounded like an honest opinion... Until I got to the last sentence. You wrote a self-fulfilling prophecy.
rubslopes··on South Korea police arrest man for posting AI photo of runaway wolf
If this was true, they should have contacted the user nevertheless.
rubslopes··on Habitual coffee intake shapes the microbiome, modifies physiology and cognition
Was this thread invaded by AI? Casually reading the first comments, 3 different users mentioned they had a recent "mental health incident" related to caffeine??

rubslopes··on Drunk post: Things I've learned as a senior engineer (2021)
I had more luck finding "similar minds" in academia.
rubslopes··on Kimi K2.6: Advancing open-source coding
Before GLM-5.1, I was going back and forth between Opus 4.5 and Kimi 4.5 and having very good results with Kimi.
rubslopes··on Dad brains: How fatherhood rewires the male mind
My first child is still 16 months old, and I already feel like this.
rubslopes··on Vercel April 2026 security incident
I just wanted to chime in and say I think he is knowledgeable; he's not a con. I know you didn't say that, but people might have the impression he doesn't know what he's talking about. He does know, and I've learned quite a lot from him in the past.

However, since the LLM Cambria explosion, he has become very clickbaity, and his content has become shallow. I don't watch his videos anymore.

rubslopes··on Arguing with Agents
There's a Wikipedia article with a nice list of LLM writing patterns:
