Se llama “How to Speak” y durante más de 40 años fue una de las charlas más legendarias del MIT.

Patrick Henry Winston, profesor del MIT, tenía una idea muy simple, tu forma de comunicar puede cambiar tu vida.

Pedirle a la IA que resuelva un problema de código lleva menos de 2 minutos.Tienes tests en verde y código funcionando.Ahora pregúntate: ¿Qué has aprendido realmente?Para la mayoría de desarrolladores, la respuesta es: Nada. Abro hilo sobre la crisis silenciosa del código generado 👇

🧩 Claude Code tiene 7 formas de decirle cómo trabajar.

CLAUDE.md, rules, skills, subagents, hooks, output styles y el append del system prompt.

Pero no todas cuestan lo mismo en tokens. Ni de lejos.

Anthropic ha publicado la guía más completa que han hecho hasta ahora: tabla de costes, comportamiento en compactación, y criterio para saber dónde meter cada instrucción 🧵

Building a game is a great way to improve your programming skills.

It makes you consider things like performance, user input, and structure while getting creative with your problem-solving.

In this guide, @manishmshiva walks you through some of the key skills game dev helps you sharpen.

Well, here it is! We just shipped the very first version of Lucky Engine - a game engine purpose-built for robotics. Download now on Windows, Linux, and macOS - free for research & personal use: https://t.co/NT2j8lZWlI

Go train some robots... or make some games. This is just the beginning, and we're planning to update frequently as we keep working hard. ❤️

Containerization is at the heart of modern software development.

In this in-depth course, Eissa teaches you Docker from the ground up.

You'll learn about containers, Dockerfiles, images, Docker Hub, networking, volumes, Docker Compose, and more - plus real-world deployment workflows.

Are they teaching Computer Science Wrong - and Why?

https://t.co/7OOord1gIx

Here are this week's topics!

00:21 - How do we help younger generations develop the systems-thinking skills?
01:31 - How can someone learning best apply these lessons today?
05:47 - But how do you start? Which languages are manageable to start with on your own?
07:28 - Why do you think that universities and CS programs don’t start from the limited hardware basics?
09:55 - Couldn’t you get a (comprehensive) book and learn a lot that way?
10:43 - What has been your experience with graphics programming ?
12:28 - I’m 30 and just learned my Dad has autism. Any advice?
13:40 - TRS80? Commodore? Try a KIM-1 entering machine code on a hex keypad.
16:12 - In Regina - did you ever run up a phone bill?
17:33 - One of my memories is trying to design a database for my photos. I eventually gave up and years later got an Access database
19:44 - 10 Remember when you.. 20 Were running out of lines numbers… 30…?
20:33 - What to use variable arguments for?
21:03 - Doesn’t the new operator use malloc wthin the runtime?
21:30 - I always thought kernel allocated pages and malloc dealt with fine details of partitioning it ?
22:06 - Why do you need all the layers, instead of just one system call to allocate memory?
22:40 - Isn’t C main variable args?
22:57 - Can you talk about how that’s different from a C++ pure virtual base class that also doesn’t change?
24:24 - Wasn’t the plan for WindowsRT to be the new start Windows, without backward compatibility?
25:29 - What Windows API methods Dave you have originally implemented?
26:04 - Do you also have odd tools that you stuck with from the past? Maybe some small tools you wrote yourself?
27:35 - Have you ever programmed using a teletype?
28:25 - Thank you for finding a way to get me check, I know know the, why in the way I am. Has anyone thanked you for that before?
29:08 - Nicely done! I 1000% agree with what you lay out in this episode - THANKS - My ONLY critique is …
31:07 - I think this “low tolerance for ambiguity” is most programmers?
32:00 - Why would anyone want to hire a boring neurotypical without any superpowers?
33:15 - I think what you’re discussing is the nature of someone not willing to accept what’s known as Nelsonian Ignorance
34:06 - Is it worth getting diagnosed late?
35:35 - Do we require scarcity for people to act as though resources are scarce?
36:19 - Can Dave tell us the story about the bozoliveshere registry key?
36:35 - Another UofR CS grad here…. did you get to play Star Trek on the Sigma 9 via TTYs, toggle in the bootstrap for the PDP-11/20?
37:09 - As a fellow Canadian, I get a Stuart McLean vibe from this. Gonna call it Prairie Home Computer Companion.
37:35 - Hey Glenn, what happened to your audio for this episode?
38:03 - On Air Mesmerizer is great? Will that be available for those of us with Mesmerizers?
39:04 - Your from Saskatchewan? Epic
39:21 - Did’ja ever run into Joni Mitchell?
41:41 - Outakes and an old man joke…

Aprender inglés requiere tu esfuerzo. FreeLingo pone todo lo demás:

Plan de estudios A1-C2
Gramática y vocabulario estructurado
Listening y reading a tu nivel
Chat y voz con tu tutor IA

Tu tutor IA evalúa tu nivel y crea tu plan. Tú solo tienes que registrarte y comprometerte.

🛠️ Maybe you've heard about WebMCP, but if you'd like to see it in action and learn how to work with it? I made a small site to demo how it works, how agents use it, what the spec looks like, and some important links.

It's interactive! Use the extension to actuate the page:

The @code team released a new Introduction to Agent-First Development series.

It breaks down these 5 pillars behind great agent results 🧵

• Programming language design: types, memory safety, bootstrapping
• When abstraction improves performance
• Anecdotes from building C++
• Thoughts on AI writing C++
• Mistakes he'd change while building C++

Unpopular opinion: "AI makes everyone a developer" is true the same way "cameras makes everyone a photographer"

[Puneet Patwari @system_monarch]

I have 12 years of experience and working as a Principal Engineer @Atlassian and I have seen concurrency scaring the hell out of a lot of junior engineers.

It’s one of the most feared topics in system design & backend interviews — race conditions, deadlocks, thread pools… you name it.

But once you internalize these 20 must-know concepts, everything clicks.

Save this thread. Read till the end.
Your future interviews and production systems will thank you.

Te gustaría poder evaluar una Epic en apenas unos segundos y saber:

- La calidad de la definición y cómo mejorarla
- Si está bien descompuesta en tareas
- Cómo va la ejecución y qué riesgos hay
- Recomendaciones

Es la nueva skill de Claude EM v1.2.0. Link abajo 👇

In 20 years, vibe coders will look at the Linux kernel repo the way we look at the pyramids. In awe, unable to imagine how they managed to drag all those giant stones and pile them up in the middle of the desert.

En vez de tirarte horas viendo una película random, mírate esta masterclass para aprender Claude Code desde 0 y aprender a programar con IA.

Vale la pena cada segundo! ⬇️
