No magic. No AI. Just me, a spreadsheet, and the growing realization that perhaps the robots weren’t replacing us that quickly. Then I ran the company’s shiny AI classifier and calculated precision and recall. The results? Recall: a painful 42%

@Decolar O atendimento diz que a compra na passagem é na verdade uma compra de direito pra participar de uma corrida de checkin online. Só ganha o direito de voar quem faz checkin primeiro, os demais perdem o dinheiro e a viagem

[Tiago @timotta]

Comprei passagem na @Decolar apesar das recomendações contrárias. Me ferrei. Deu ovebooking e vou perder minha viagem e eles não resolvem nada... Nunca mais...

Bitbucket pipelines is by far better than github actions

[Tiago @timotta]

For most production workloads on Kubernetes with HPA, a moderate target (around 60–75%) with realistic requests and no/loose CPU limits is usually the best default. A “90% target + high limits” strategy causes worse latency, slower reaction, and more noisy-neighbor risk.

@gabrielskyz This is the 4th year I'm using it, and the first year that I did not have to change the code due to changing in the csv exported by B3. Maybe its a good idea to opensource it now

[Tiago @timotta]

Once again, present-day Tiago is thankful to past Tiago for building a tax filing calculator for B3 stock buy/sell statements 😅📈

First time executing two agents in parallel to change complementary things to delivery same feature

With LLMs influencing the world in education, journalism, politics, and the legal field, the future of humanity may begin to be shaped by a war of generating and optimizing online content.

Trainning a model in one laptop, trainning another model in the other laptop. No memory or CPU left to play...

Amazon S3 files remembers me the time we share files and configuration by using mount filers

@alexwg It's not hard to believe in the "clone" neurons, but it's hard to believe in the emulation of response of the environment in those neurons. How did you ensure that the digital brain got the same "reward" when touch the food, as the original brain?

[Tiago @timotta]

Did I deliver this project faster than I would have using the traditional approach? Surprisingly, the answer is no. Vibe coding is so fast that it broke my usual habit of working iteratively and cutting scope.

@AnxiousWeepy There is a limit, i reached it. So I started using kilocode with minimax, and also reached to its free limit.

[Tiago @timotta]

I’ve been using OpenCode with Minimax lately and barely writing any code myself. Not sure if I’m actually moving faster or just feeling more comfortable. Maybe the real boost in velocity comes when juggling multiple projects at once

[Tiago @timotta]

First I was upset with kilocode because it kept asking to switch from plan mode to code mode, and when I said yes, it got stuck. Now I’m upset because it never asks to switch modes and just executes in plan mode.

[Tiago @timotta]

Now I don’t write code anymore, I’m a technical product manager. I just tell the kilocode what I want to build and talk it through any mistakes.

[Tiago @timotta]

Your job as an engineer isn’t to sound smart in meetings. Your job is to build the right thing. And you can’t build the right thing if you’re not willing to look stupid long enough to understand what “right” actually means.

Example of a naive mistake that a junior dev make, and also the AI: We want to not show the form if there is no available items. It uses "available_items == 0" selection to hide the form and show a message. But it ignores future bugs that can make available_items be <0.

[Tiago @timotta]

@AnxiousWeepy M2.5 its working fine for now. Its the first time I could manage working only as a supervisor of the IA (I never tried opus or sonet yet)
