What happens when you INSERT a row in Postgres? Postgres needs to ensure that data is durable while maintaining good write performance + crash recovery ability. The key is in the Write-Ahead Log (WAL). (1) Postgres receives the query and determines what data page to place it…
How do we design effective and safe APIs? APIs have increasingly become the backbone of modern software. To understand some of the key principles and best practices of API design, Let's analyze a social media platform example: 🔹 𝗥𝗲𝘀𝗼𝘂𝗿𝗰𝗲 𝗻𝗮𝗺𝗶𝗻𝗴 ↳ Clarity is…
Si quieres que tus aplicaciones sean rápidas, estables y escalables.. Tienes que entender un concepto clave: colas y jobs. Es uno de esos temas que separa al PROGRAMADOR JUNIOR del que ya piensa en arquitectura. Aquí te explico qué son, cuándo usarlas y cómo funcionan 🧵👇
Many DevOps Engineers don’t fully understand how DevOps and GitOps CI/CD pipelines differ. In a DevOps CI/CD pipeline, everything runs in one flow from code commit, tests, build, image creation, to direct deployment into the Kubernetes cluster. It is fast and centralized but…
There is a reason why System Design is hard for most software engineers. They don't understand how distributed systems work. If you want to learn the basics of distributed systems, read these 13 curated articles: ↓
If you want to become good at system design (in 3 weeks), learn these case studies... 🧵
Si no entiendes el versionado de APIs, tarde o temprano romperás algo en producción. Y lo peor: puede que ni te des cuenta hasta que un cliente o tu jefe te llame gritando😅 Aprende qué es el versionado de APIs, por qué importa y cómo hacerlo bien 🧵👇
This guy literally breaks down how AI is reshaping the entire software development workflow
Es excelente esta alternativa a Postman. La usé en el último año y es buena, fácil de usar e intuitiva. No se va a caer porque AWS no esté. Tremendo plus.
Llevo usando Bruno unos días para probar APIs y es buenísimo. Rápido, sencillo, offline e intuitivo. Mucho mejor que Postman, el cual voy a abandonar tras años usándolo. Si quieres cambiar, puedes importar todas tus colecciones de Postman directamente en Bruno!
El Sábado nos escuchamos para charlar sobre por qué Java sigue siendo relevante

Your cache isn’t broken because of LRU. It’s broken because you forgot TTL. Why LRU Alone Fails 1. Stale data: Hot keys never expire. Yesterday’s price lives forever. 2. Idle memory: If the cache never fills, nothing gets evicted. Dead keys stay. 3. Broken correctness: Wrong…
🐳 @Docker hizo que DevOps fuera más rápido, más liviano y más portátil. Pero, ¿cómo funciona realmente bajo el capó? 1. Cliente Docker: ejecuta comandos como docker build, docker pull y docker run. 2. Docker Host (Daemon): El demonio de Docker escucha estos comandos,…
I regret not mastering this as a junior developer: - SQL, data modeling, indexing I don't think it's realistic to expect you to truly master it as a junior. However, simply learning about these topics puts you far ahead of everyone else. SQL databases have been around for 40+…
Never call an API in a transaction. In relational databases, it's best practice to keep transactions as short-lived as possible. Longer transactions lead to more resource contention. If each transaction acquires row locks, being longer-lived means higher likelihood of lock…
Indexes are one of the most critical concepts for databases. But to use them effectively, you need to know how they work under the hood. Here are the fundamental concepts that every backend engineer should know: ↓
