I always found Dunning-Kruger effect to be a very interesting thing: the overconfidence of non-qualified people to perform highly-qualified activities, mostly because it is so real. This post talks about the scaled DK effect that's going on in the tech world. christianheilmann.com/2025/10/30/a...

THIS is what I'd call green policy! Come onnn! Kudos to Australia 👏 electrek.co/2025/11/04/a...

Found a great new use for ChatGPT, specially the voice chat: practice my #Chinese speaking. 🇨🇳😁👌

I’m learning Chinese, because yes 😂 I’ve failed to learn French, Italian, and German — so failing at a new language ain’t this hard anymore. But MAAAN Chinese is hard. I feel like I’m not smart to learn a new language anymore. 😩 But I felt like this while learning English and so here I am.

Interesting SWE read. Contains good advices on how to build great software fast, resilient to changes, and how to focus on value-oriented engineering. charemza.name/blog/posts/a...

You know what came to mind these days? #CoffeeScript. A language that brought some elegance of #Ruby to #JavaScript, and made the DX of writing front end code WAY better. I miss it. I honestly think CS, as a language, did great, and deserved to be preserved and reside amongst us till these days.

Really nice 101 on what MCP is about. youtu.be/FLpS7OfD5-s

Hey folks! We have a CVE up for #AshFramework bypass policies. It's a *highly unlikely edge case*. But, as always, we take security extremely seriously and will always follow proper procedure here. Props to @maennchen.dev for reporting and resolving 🙇

This is such a GREAT comparison over performance of different Python versions over Linux, macOS – and even against Node.js 24 and Rust! Interesting times for Python developers. blog.miguelgrinberg.com/post/python-...

Nix is a great piece of tech — but these constant political fires being lighted up makes me wonder a bit how stable are the collective of people behind it. It feels like there’s a need for some people to learn how to work collaboratively.

I'm having a good chat w/ ma friend ChatGPT over a distributed system issue and he recommended me using bloom filter over HyperLogLog (my first assumption over a possible/best solution for the problem), and 🤯 OMG – Bloom filters are this absolutely mind-blowing super-clever thing! I am literally 🤯!

Interesting piece of advise for SWEs over AI and code/engineering. Write the Damn Code, by Anton Zhiyanov. 👉 antonz.org/write-code/ "(...) Get involved with the code, don't leave it all to AI." 👌

And Torvalds strikes again, now against the "stupid helper" 😂 👉 lkml.org/lkml/2025/8/... I'm a big fan of Torvalds – he's a GREAT engineer and personality, and I do fear what the world will be after he's gone. But he can't be taken as a role model when it comes to communication. 🤦‍♂️😅

Among other #Postgres feats beings released in v18, one stood out for me: UUIDv7 is not built-in. What a great news! 👌 www.postgresql.org/about/news/p...

Every single time I open #LinkedIn to check if there are smt worth reading, I get myself upset by reading BS that's so absurd, so cuckoo crazy, so non-logical that I doubt these absurdities are made out of lack of knowledge. They're not. These are posts made out of a pure desire to mislead people.

TIL how to take full-page screenshots on both Chrome n Firefox (and their variants): In Chrome, open DevTools → Cmd+Shift+P → type "screenshot" → choose "Capture full size screenshot" In Firefox, right-click the page → "Take Screenshot" → "Save full page" These feats were there, all the time... 🤯

Hoje tropecei nessa talk excepcional do Renan – nosso querido Milhouse, sobre a runtime Elixir/Erlang, no @elug-ce.github.io. #elixirlang #myelixirstatus Excepcional é pouco pra descrever! O Renan explica *no detalhe* o porquê de Elixir/Erlang ser tão bom em paralelismo. 😍 👇 youtu.be/ZOQzS3wEBCo

I recently had issues with insanely high disk usage in macOS, and I tried a multitude of approaches to solve it somehow. After *months* in struggle, the two actions that got free space back was: 1. remove WhatsApp Desktop (30~40GB for cached conversations; ???) 2. rebuild Spotlight index (~30GB!)

I'm not one of these blind fans of AI/LLMs who think they'll take all the jobs, run the world, bla bla bla – they're tools, quite useful and very powerful, but still, tools! But, given this statement, omg I'm so GLAD these things exist! What a GREAT TIME to be a software engineer! 😄

This Projects feature in ChatGPT (and other AI chats) is a game changer! Given that you can upload files to be used as context, set up a system prompt that’s used by all Projects chats, and have in-ctx chats grouped together makes my AI discussions over software Eng & architecture WAY better!

I’m a fan of the Game of Thrones show. I watched it many times, and I love to see flashes of the show on YouTube. One of the characters I admire the most is Brienne of Tarth. She’s a knight in every possible way: honorable, loyal, fearless, skilled in swordplay and experienced with real battles. +

Simon Willison is once more teaching us smt, w/ "LLMs are like a lossy encyclopedia." I like the analogy. simonwillison.net/2025/Aug/29/...

TIL WTF are HyperLogLogs. TLDR: it's **pure magic!**

Yep, I just cleaned a 5K+ unread emails inbox. I'm feeling so much totally entirely definitely a responsible adult right now 😂

TIL about this insane amount of people who died on Everest. Seriously — WTF is wrong with these people? Escalating the highest and deadliest mount in the world just to… get back right after, while seriously risking your own death. Sorry, but I prefer hobbies simpler, safer. youtu.be/2XOD4b5uwfg

One fun thing of learning a new lang is when you get exposed to the most silly puns of the lang you’re learning. You get so happy for getting the pun! It’s a true sign that you’re progressing with language understanding and comprehension. And some puns are really fun!

I've possibly found a new digital hobby: mapping my local area on #OpenStreetMap 😂 I'm literally adding places I've been, and I'll put some effort to add as many small businesses as I get, in an effort to help them "show up" to the world. (I'm adding them to Google Maps as well, but I <3 OSM more.)

Oh god! With all that’s happening in Brazil and the world, these otters surely made me smile quite well ❤️

Carlos Sousa @caike.bsky.social tem um convite especial pra você. Bibliotecas Elixir para Redes Descentralizadas 🧙🏼‍♀️

When I see these people crazy-posting online their super-human productivity, doing so many stuff, apps, libraries, Open Source, indie apps, etc., etc., in so little time... All I can think of is: MARKETING BS. 🤨 There's no way one can do so much quality stuff like these dev influencers. Just NOPE.

@angad.me Hey bro, nice work hacking the cruise's WiFi 👍

Deep Blue is 30 years old and was capable of defeating chess grand champions. It could be housed in a single cabinet. ChatGPT spans untold data centers devouring massive amounts of electricity and it got its ass whipped by an 8 bit gaming console from the 1970s.

Anyone here having good experiences with #openSUSE and their distros? I'm looking at this #MicroOS and it sounds interesting for containerized workloads.

Been studying #Nix and #Guix for their immutable pkg management aspects, etc. – and I'd love if Nix was built on top of a LISP-like language like #Guile. The Nix language looks a bit weird, I'm always having WTF moments while I read it. In the end, I'm thinking on building smt for my #Homebrew...

First time flying w/ this company Transavia. My seat is the mid one and I got here first — now I’m concerned my fellow seatmates will have to fly seating in each of my knees. 🤦🏻‍♂️😂 Gosh! This might be the smallest plane I’ve taken in my whole life! 🤏

I’m having lunch in this fancy place in Amsterdam, and after asking for a grilled salmon with vegetables they gave me this super fancy plate with salmon and some vegs I have no idea what they are 😅 And Dutch aren’t the friendliest people on the world for silly questions so I’m not asking. 🤦🏻‍♂️😂

Ok, this Friendly SQL section over @duckdb.org really made me 😮 over #DuckDB itself. duckdb.org/docs/stable/...

I just found out about #OnlyOffice and... 🤯 And it's free n open source. Damn! There's so much good stuff available in the FLOSS world these days. Is there anyone using it already, somehow? Perhaps in pair with Nextcloud or smt else?

The current market wants lean, profitable, efficient companies and that requires tech that can be that. Bang for the buck. The current world climate demands things that are reliable and resilient, both technically and culturally. Elixir makes sense in this world. I hope folks see it.

As a Brazilian developer I always found it hard to understand the value of apps super-optimized for poor connections in 2020s. Well, I always took it seriously cuz “some client might be trying to buy smt remotely, and we NEVER lose sales!” — but still, it was hard to “picture” it in my mind. +

There's smt I really miss from GHA (GitHub Actions): the ability to run the CI for multiple commits in a given branch at once. Eg.: I push a branch with 5 commits, and the CI would run for each one of them. I think it's really good to have the green check in every-single-commit of my Git history.

I think one of the biggest strategic mistakes with LiveView was the whole "fuck JS" mood it pushed. You can't go into someone else's house, take a shit on their floor, and expect them to take you seriously. #ElixirLang

I often see or hear people complaining about how #LinkedIn is mostly non sense content being posted t wildly, and I a bit cetic on it. But then, I visit the place. People praising AI for things it doesn’t do, suggesting expensive tech stacks because “they’re shine”, crazy stupid React “techniques”,
