This is, unfortunately, a usual "mistake" these days. It's now common to see the Brazilian flag next to "Portuguese" in dropdowns and listings. E.g.: https://www.duolingo.com/course/pt/en/Learn-Portuguese

RANT! You've been warned.

> Voice Presets are available in 18 languages: Arabic (Emirati, Modern Standard), Brazilian (Portuguese), Catalan, Chinese (Mandarin), Dutch, English (American, British), French (France), German, Greek, Hindi, Italian, Korean, Norwegian, Russian, Spanish (Spain), and Vietnamese.

Brazilian (Portuguese)? Folks, c'mon... It's OK you don't care about Portugal - I mean it - but Brazilian is NOT a language. Why didn't you write "American (USA, British)" too?

jcmfernandes··on Janas: Run LLMs larger than RAM by streaming experts from SSD
What you said about the RTX 6000 was kind of my point. Local AI is feasible today, but only few people will be willing to drop 20k+ on a graphics card. I'm less optimistic than you on the timing of the trickle down, but I hope you're right! :)
jcmfernandes··on Janas: Run LLMs larger than RAM by streaming experts from SSD
Latency is the remaining hurdle for local AI. We'll get there, but my prediction is that it will take around 10 years.
jcmfernandes··on New MCP Roadmap
I would prefer a core transport agnostic protocol, and then see MCP-over-HTTP being a spec on top of that.
jcmfernandes··on OTel isn’t going well
Ran into the same issue and didn't find any willingness in the OTEL gods to close this gap.
jcmfernandes··on Azulejo
Indeed, it's sad. They are staple here in Portugal, covering entire buildings. Beautiful examples: https://maps.app.goo.gl/3BK1BoMVsgRY38eG8 and https://maps.app.goo.gl/fquP923g13xtbSxU8

I would love to help, but it's not my domain. I, unfortunately, witness the side-effects of people stealing them on my day to day. There are many shops in Lisbon that sell them, and there's even a beautiful museum here that it's definitely worth visiting (or signing up for a workshop!): https://museunacionaldoazulejo.gov.pt - it's currently closed for renovation; it should reopen later this year, but that's yet to be confirmed.

When buying - on the streets or in a shop - if it looks old, unless provenance is absolutely clear, please don't.

jcmfernandes··on Azulejo
Doing a little activism here: please don't buy old ones while visiting Portugal/Spain/etc., as they are commonly stolen goods. Thanks, from Lisbon.
jcmfernandes··on ZCode – Harness for GLM-5.2
Are you using openrouter or something else?
jcmfernandes··on WATaBoy: JIT-Ing Game Boy Instructions to WASM Beats a Native Interpreter
Very cool! I did something similar using Dolphin and LLVM, 16 years ago during my masters, for a course on virtual machines. I compiled the interpreter to LLVM bitcode and then used it that to build basic blocks. It was super slow, but it worked, and I had lots of fun working on it.
jcmfernandes··on Use your Nvidia GPU's VRAM as swap space on Linux
Q: Why? A: Why not?
jcmfernandes··on I think Anthropic and OpenAI have found product-market fit
These folks have no lasting moat and they know it. We are still close to the November 2025 inflection point, so they had a clear advantage during these past few months. That will soon fade as open-weights models become really good, which is arguably already the case with DeepSeek V4.
jcmfernandes··on Cloudflare to cut about 20% of its workforce
I find it surprising that the word "incident" doesn't yet show up on this page. Cloudflare had at least two nasty incidents a few months ago. It certainly shook my confidence in the company's ability to run its infrastructure.
jcmfernandes··on VibeVoice: Open-source frontier voice AI
I totally get you, but this is yet another thick layer away.
jcmfernandes··on VibeVoice: Open-source frontier voice AI
Indeed. We now live in a world where freeware is named open source. We are very sorry, Stallman.
jcmfernandes··on Chuck Norris has died
It was super popular in Portugal.
jcmfernandes··on John Carmack about open source and anti-AI activists
> and the GPL would prevent outright exploitation by our competitors, but those were to allay fears of my partners to allow me to make the gift.

I can understand his stance on AI given this perspective. I have a harder time empathizing his frustrations. Did he also have a hard time coming to terms with the need for AGPL?

jcmfernandes··on Why Go Can't Try
I just read the article and I didn't get away with that rationale. Now, this isn't to say that I agree with the author. I don't see why go would *have* to add typed error sets to have a try keyword.

Yes, mimicking Zig's error handling mechanics in go is very much impossible at this point, but I don't see why we can't have a flavor of said mechanics.

jcmfernandes··on Do not apologize for replying late to my email
I'll continue apologizing. I'm very sorry, though.
jcmfernandes··on Cloudflare acquires Astro
I'm not! Just preparing myself for the worst-case scenario and creating some bookmarks meanwhile.
jcmfernandes··on Cloudflare acquires Astro
Damn. What alternatives does HN recommend?
jcmfernandes··on ChatGPT Health
Totally. I was in the ER, hitting my head against the wall because of the pain. And when the doctor cut it open... it was so painful, but the almost instant relief was worth it.
jcmfernandes··on Bose has released API docs and opened the API for its EoL SoundTouch speakers
It makes me want to buy both! Old to tinker with, new to support the move.
jcmfernandes··on ChatGPT Health
I have a very similar story. It went from ibuprofen and water to antibiotics the following day, to different antibiotics the next day, and finally to having my tonsils purged (i.e., cut open) with local anesthesia in 4 days. By this time I no longer could speak. It was the most pain I felt in my life.

I still trust doctors, but this made me much more demanding towards them.

jcmfernandes··on Opus 4.5 is not the normal AI agent experience that I have had thus far
Depends on the software. IMO, development speed will increase, but humans will continue to be the limiting factor, so we are safe. Our jobs, however, are changing and will continue to.
jcmfernandes··on Opus 4.5 is not the normal AI agent experience that I have had thus far
To the author: you wrote those apps. Not like you used to, but you wrote them.

IMO, our jobs are safe. It's our ways of working that are changing. Rapidly.

It worked in the past.
jcmfernandes··on Nimony (Nim 3.0) Design Principles
>WCET ("worst case execution time") is an important consideration: Operations should take a fixed amount of time and the produced machine code should be predictable.

Good luck. Give the avionics guys a call if you solve this at the language level.
