It is time → effect.institute. 2026, the year of 𝚎𝚏𝚏𝚎𝚌𝚝. I'm extremely proud of how this turned out. There are many chapters to add, but I do hope you enjoy what's there so far. Let me know what you think. 🫡

everyone's talking about their teams like they were at the peak of efficiency and bottlenecked by ability to produce code here's what things actually look like - your org rarely has good ideas. ideas being expensive to implement was actually helping - majority of workers have

"Code Is Cheap Now. Software Isn’t." The barrier to entry for building software has collapsed. The barrier to building something that matters hasn’t moved an inch. by Chris Gregori chrisgregori.dev/opinion/code-i…

🇧🇷 Brazil’s Pix payment system now processes more transactions than Visa and Mastercard combined 🤯 According to Banco Central do Brasil, Pix handled 224+ million transactions in a single day, overtaking the combined domestic volumes of Visa and Mastercard. Let’s put that into

AI is making CEOs delusional

Does any of it violate copyright? According to Anthropic itself, their devs do not write any code by hand. As far as I know, AI-generated code is not copyrightable under US law. So correct me if I'm wrong, but you should not be able to use the DMCA to take down this code, right?

Database table size impacts performance in more ways than one: a) B-tree depth. Using 8k pages and a 16b uuid: 1 level = ~370 rows 2 levels = ~138k rows 3 levels = ~50m rows 4 levels = ~20b rows The lookup cost on a table with 100k rows is not the same as one with 1b rows. This

Most teams believe that speed comes from moving fast and iterating quickly. But speed in software is cumulative: decisions made early either accelerate or slow down everything that follows. A poorly designed system doesn’t become fast with time, it only becomes expensive.

I've tried for years to draw layers vs hexagon, this is the best I've been able to manage on my side:

staff/senior engineer thought:

Refactoring is frequently postponed because it doesn’t deliver immediate business value. However, every postponed refactoring becomes a hidden cost in the system. Complexity accumulates silently, until simple changes require disproportionate effort. What is delayed today becomes

Speed without structure doesn’t scale. I mean, what works for a team of five breaks at fifty without clear ownership and boundaries, and fast decisions turn into inconsistent ones. The challenge is building systems that remain coherent as you grow.
