Estás tirando tokens a la basura con tus agentes y ni te estás enterando. Hacer 20 llamadas seguidas a APIs para filtrar 3 datos satura el contexto, dispara la latencia y te infla la factura. La alternativa es Code Mode: que el modelo escriba el script, lo ejecute en un sandbox y te devuelva solo lo que necesitas. En datos es de locos: - De 22 steps a 2. - De 200 KB en contexto a 1 KB. Dentro vídeo explicándolo en profundidad👇

Ep, vengo a dar un poco de autobombo a una idea que llevo un tiempo usando yo solo. Trabajando en empresas donde el español no es la lengua principal, a veces pasa que, ya sea por falta de contexto o por diferencias culturales a la hora de expresarse, cuesta un poco entender a qué se está refiriendo un compañero cuando te explica algo o te da feedback. Muchas veces hago follow-up y pregunto para asegurarme de no malinterpretar nada, pero otros días simplemente mi coco no da para más y acabo usando ChatGPT para que me diga por dónde van los tiros. Así que hace un mes o así creé Entiendo. Haces highlight de cualquier texto y puedes preguntarle rápidamente a GPT qué cree que quiere decir, si puede haber un segundo sentido o, si la conversación está escalando, cómo desescalarla. Es 100% gratis, usa el sign-in de ChatGPT (dios les bendiga) y no guardo absolutamente nada de info de la conversación. Está en castellano, inglés y catalán. Pero entiende cualquier idioma por el que pidais feedback. Si la queréis probar: madebysignal.dev/es/entiendo…

Let's admit it: AI models write better code than many engineers. Where does this fact leave the engineers? What should they do? The answer is guided by this reality: models still aren't capable of thinking at high-level and have a deep understanding of systems. That's why, more than never the System Thinking and Design are more important than ever. Engineers need to shift their mindset to an Orchestrator role, architecting the high level of the systems meanwhile the AI models do the low level tasks and coding. #SimoSharesAI

Clave para cualquier EM / Tech Lead :)
As a Tech Lead, “we need more speed” always comes up. Without KPIs, SLIs, and SLOs, that turns into opinions: “I think it’s fine.” // “I think it’s risky.” This is why Operational Excellence matters. 👇

Use /init before start working on the project to create your claude.md file. "Your claude.md is your AI's instruction manual. Write it like you're onboarding a new developer. Because you are."

Spend time on planning. More likely Claude will succeed. Use shift-tab to cycle to plan mode.

Move faster by avoiding permissions to basic commands: 𝗰𝗹𝗮𝘂𝗱𝗲 --𝗱𝗮𝗻𝗴𝗲𝗿𝗼𝘂𝘀𝗹𝘆-𝘀𝗸𝗶𝗽-𝗽𝗲𝗿𝗺𝗶𝘀𝘀𝗶𝗼𝗻𝘀

Support new lines / multi line prompts in the terminal: /𝘁𝗲𝗿𝗺𝗶𝗻𝗮𝗹-𝘀𝗲𝘁𝘂𝗽

Prepare your dialogue before communicating. Think before talking, not during communication. What do you want to communicate? Draw a mental map and then communicate. The communication will flow, you'll sound more fluent, avoid empty gaps and be more concise. #SimoTips

📊 El 𝐅𝐚𝐢𝐥𝐮𝐫𝐞 𝐫𝐚𝐭𝐞 en @AdevintaEng es de 2.34% 🤔 ¿Esto es bueno, o es malo? Pues depende 🤷🏻‍♂️ Hay un tradeoff ⚖️ entre velocity y failure rate. Tener un failure rate tan bajo significa que podemos correr más, podemos arriesgar un poquito más 🤪.

PowerLevel10K, probably one of the most complete OhMyZsh theme. Easy to install and configure github.com/romkatv/powerleve…
👋 These days, I'm starting (attendee) a course about effective communication, I'll share relevant tips under the #EffectiveCommTips hashtag. Stay tuned! 🫵
CSV manipulation and cleanup: Miller (miller.readthedocs.io/en/lat…) JSON filtering and manipulation: JQ (stedolan.github.io/jq/manual…) These two made my day
GIT tip: you can have a global .gitignore file, to exclude stuff you only use or maybe ignore .idea folder (docs.github.com/en/get-start…)

Trying this new Slack configuration: - Dark mode - Compact mode Let's see...
My very trustable source of Slack emojis (slackmojis.com/). Use it with care!

Today's tip: Dualless Chrome extension (chrome.google.com/webstore/d…) to easily split your tabs into windows

This will super improve your team's productivity using Slack (slackmojis.com/). No.
