Hace poco me escribió alguien que escuchó este podcast que grabamos hace casi 2 años ya (cómo vuela el tiempo!) y creo que nunca compartí esto por aquí. bit.ly/corpcast

AI is making CEOs delusional

In December my blood pressure scared me, prediabetic levels, I weighted 197.3 pounds (89.5k) In Jan 1/2026 made some changes: 1) Zero alcohol 2) Workout 60 mins daily 3) Eat healthier 73 days later: I have lost 22 pounds, no fancy methods, just discipline and work.

@Ineslaram (2/2) alguien que no ha desarrollado apps complejas no sabe como describir eso. Luego, cuando ya Claude lo programó, es bastante impresionante en algunas cosas, bastante tontito en otras. Hay que probar todo, y corregir bastante (no en código, sino en más instrucciones)

@Ineslaram (1/2) igual me pasó, hace 1 semana empecé un proyecto de cero en un stack que conozco muy bien, para evaluar la calidad del resultado. Primero, el planning y el nivel de detalle de la arquitectura del sistema, esquema de base de datos, sistemas de colas, integración de APIs

Estoy construyendo mi primer proyecto con Claude desde 0. De momento veo un poco complicado que alguien que no sepa programar pueda hacerlo. Que pensáis ?

Claude can now build interactive charts and diagrams, directly in the chat. Available today in beta on all plans, including free. Try it out: claude.ai

90% of stand-up meetings look exactly like this.

The token cost to build a production feature is now lower than the meeting cost to discuss building that feature. Let me rephrase. It is literally cheaper to build the thing and see if it works than to have a 30 minute planning meeting about whether you should build it. It’s wild when you think about it. This completely inverts how you should run a software organization. The planning layer becomes the bottleneck because the building layer is essentially free. The cost of code has dropped to essentially 0. The rational response is to eliminate planning for anything that can be tested empirically. Don’t debate whether a feature will work. Just build it in 2 hours, measure it with a group of customers, and then decide to kill or keep it. I saw a startup operating this way and their build velocity is up 20x. Decision quality is up because every decision is informed by a real prototype, not a slide deck and an expensive meeting. We went from “move fast and break things” to “move fast and build everything.” The planning industrial complex is dead. Thank god.

What does it mean for software engineering when we no longer write the code? Here's the take from Boris Cherny (@bcherny), the creator of Claude Code.

Boris automated himself out of code review well before AI. Boris was one of the most prolific code reviewers at Meta company. And he worked hard to minimize time spent on code review. His system::every time he left the same kind of review comment, he logged it in a spreadsheet. Once a pattern hit 3-4 occurrences, he’d write a lint rule to automate it away! 2. PRDs are dead on the Claude Code team: prototypes replaced them. Instead of writing Product Requirement Documents (specs), they build hundreds of working prototypes before shipping a feature. Boris: “There’s just no way we could have shipped this if we started with static mocks and Figma or if we started with a PRD.” 3. This is the year of the generalist (and maybe the year of those with ADHD) Boris’s work has shifted from deep-focus single-threaded coding to managing multiple parallel agents and context-switching rapidly. As Boris put it: “It’s not so much about deep work, it’s about how good I am at context switching and jumping across multiple different contexts very quickly.”

What do you see, chicken or bird🤔

@porqueTTIA AI slop

@iyoushetwt @alexasa79 Maybe on an emulator you can run it

@alexasa79 has it long gone?? 😂

What was the first code editor you ever used? Mine was Sublime Text

@sitiwayyy 7+8+9-1=23

Can anyone solve this problem?

@adsafayet depends on the brand... if your brand is black/gray/white then right... If your brand uses colors like blue/purple, then left. If you don't have branding guidelines yet, start there.

Left or Right? 🤔

@MMacDonaldCCPS ok

Leo, my wonderful Star of the Week! His growing independence earned him this week's prize. ⭐️ @corp

@Abmankendrick It depends: A if there is more info "under the fold" like a timeline, gallery, blog posts, etc.; B if this is all you will get and it's more about swiping left/right to view other profiles.

Which is Better? A or B 🤔
