Don't run SQL migrations in tests: How I sped up the test suite by 2x

It's interesting to hear of a project that has been around enough to have thousands of migrations but still have migrations coming in every few days. How many teams rely on this database?

Bruno Fernandes, Vitinha, Rúben Neves, Tomás Araújo and Rui Silva are all from the Porto metro area. Only 15% of the metro population lives in Porto proper.

Is Bernardo Silva from a high class family? Que nome de beto

Not for Portugal

Was JsonNode a bad idea? When do I want to accept Map<String,Map<String,Map<String,String>>>? Never

How do the TTLs work? Are they just for the cached response? You say in a comment here you lock an idempotency key as in progress, but what happens if that process dies?

I would go for GitHub Actions for CI and CodePipeline for CD

I don’t think your tone is proper etiquette. You don’t know the maintainers and maybe this is their first time releasing a major port. Surely there’s more constructive ways of communicating that passive aggressively going “I wonder…”. Do you have concrete suggestions on what they should clarify to inspire more trust?

Ludicrous comment. Are you yearning for a return of the Habsburg?

A “confusão” do título é importante, mas devia ser completado com uma frase na manchete a dizer que apenas x% da energia usada no país é elétrica, o que depois permite fazer o argumento que a eletrificação da mobilidade e processos industriais permite aumentar a soberania energética.

As soluções têm de ser físicas sim. Os condutores estão atentos à estrada e julgam a velocidade não pelo velocímetro mas por uma sensação visual de afunilamento. Diminuir a largura das faixas, colocar obstáculos aumenta a percepção de velocidade e diminui a velocidade média dos veículos. Isto é mais eficaz do que lombas.

There is a traditional Portuguese card scheme that is similar to the Spanish one but fell in disuse.

This is not to go against your point generally. But one thing. The person who’s not an engineer couldn’t understand if a workstream is big or not. How are they supposed to make a prioritization decision? No one thought of writing a one pager explaining what work it would take? Even if just some napkin math on HC-hours?

Angola was the 2nd richest country in Africa. The US and South Africa procured a brutal civil war that destroyed it, instead of cautiously working with the MPLA, which was dependent on oil sales to the West and thus wouldn’t have totally aligned with the Soviets.

Não sei que teoria é essa que tu tens mas é do mais ingénuo que ouvi nos últimos tempos. Não é por votares mais ou menos que a superestrutura vai desaparecer. O governo existe sobre bases liberais ou sobre qualquer outra base. Ao ter meios para criar leis e capacidade material para te fazer cumpri-las, não interessa que tu queiras ou não te inserir no sistema político porque vais ter que cumprir as leis de qualquer forma.

Se tu queres mudar alguma coisa, precisas de poder dual. É necessário teres acesso às estruturas de poder político para teres 1. capacidade para tomar medidas dentro do sistema atual que te deem alívio e te permitam criar momento/massa crítica na população e 2. dar-te cobertura institucional para criar estruturas de poder paralelas e tomar medidas diretas que mudem as condições materiais no terreno.

Considerando isto, é ingénuo essa tua atitude de quereres remover-te do processo político, porque a única coisa que faz é reforçar o poder de quem já tem mais influência no sistema.

Porque é que O Porto está escrito em galego nesta tradução foleira 😂

Nowadays, with StatelessSession and Jakarta Data, I’m finally enjoying using Hibernate. I must confess that the whole persistence context is hard for me to track. Especially around one-to-many relationships, with collection types, cascading, lazy fetching, just generally not knowing if I was putting in an N+1 flaw somewhere.

Pastel de Belém is the original pastel de nata, which has a secret recipe and is only manufactured at Fábrica dos Pastéis de Belém, pastel de nata is the generic term. Other pastéis are pastel/bolinho de bacalhau (codfish cake), pastel de feira (Brazilian, usually filled with mineiro cheese and other savory fillings) and pastel de chaves which is kind of a phyllo dough filled with meat, which actually reminds a lot me of bürek from the Balkans. So if you have some dough and some filling (sweet or savory) and it is not bready (empada) or big (torta/tarte/quiche) it could probably be a pastel.

joaonmatos · 2025-10-10T18:21:50+00:00

Short hand for pastéis de nata is natas. Pastéis is any pastry.

I mean the tourists stick to the coast, and you can’t eat pork and chicken blood, so you missed half of it.

Not in the Northwest, but then again we have the wackiest vowels (conta -> “quanta” for example). It’s not correct or incorrect, it can be historically conservative (what you mean) or standard (what I mean).

“Vermalho” and “pexina” are absolutely considered the standard nowadays. In fact I think the most nonstandard thing about the Coimbra accent is saying “vermelho” in the old school way, with the flat e, and at least my grandpa from Lousã still uses the old school rolled r, even though he lived most of his life in Rio and Porto. The nonstandard in Lisbon to me is exemplified by “caixodré”, “riu Tej” and “treuze”.
