And also a Pricing Advisor where you check the features you want, and it tells you the plan you need to get them...

So we naturally added a pricing comparison table to help understand the differences between the plans...

Each plan had its own characteristics in terms of capacity and available features. Micro and Basic had only W3C HTML checks, and for Accessibility checks you had to choose a Pro or higher plan. If you wanted HTTP Basic Auth on your reports, you needed an Agency plan. That was getting complicated!

So happy with our new simplified pricing structure for Rocket Validator! rocketvalidator.com/pricing #accessibility #saas #pricing
Screenshot of the Pricing page: "One plan. Four sizes". A selector lets you choose one of four sizes: 1K, 5K, 10K, or 50K. Another one lets you switch between Weekly, Monthly, Yearly.

Cellular automata are fascinating. Seeing how emergent behaviours arise from a discrete universe governed by simple rules never ceases to amaze me. Here’s one for you to try out: Griffeath’s demons: jaimeiniesta.com/en/demon
Screenshot of the cellular automata app. The main section shows a torus where the brown-toned texture changes as the cells are arranged. On the right-hand side, the population for each cell colour is displayed, along with statistics on these. Below that are the buttons for controlling the animation and creating new boards.

Los autómatas celulares son fascinantes. Ver cómo surgen comportamientos emergentes a partir de un universo discreto con reglas sencillas nunca deja de sorprenderme. Aquí os dejo uno para que probéis, los demonios de Griffeath: jaimeiniesta.com/es/demon #vidaartificial #threejs
Captura de pantalla de la app de autómatas celulares. La parte principal muestra un toroide donde la textura en tonos marrones va cambiando según se ordenan las celdas. En la parte de la derecha se muestra la población por cada color de celda, y estadísticas sobre estas. Debajo, los botones para controlar la animación y crear nuevos tableros.

Opus 4.8 is back! Thanks @hugobarauna.com for your help on Tidewave's Discord
Screenshot of the edit on the file ~/.claude/settings.json to set opus 4.8 as a custom model:

  }Me checking within Tidewave:

"hey ho what model are you?"

"Hey ho! I'm Claude Opus 4.8 (model ID claude-opus-4-8) — you just set it to that a moment ago with /model."

My MacBook Air M1 2020 has been getting too hot lately, likely due to the workload it's handling while using Claude/Codex. I just saw a spike at 94 degrees Celsius. Should I worry about a CPU meltdown? Time to upgrade my laptop?

Here goes an awesome update for Rocket Validator - clicking "Highlight" on an accessibility issue now opens up the affected web page, at the same device viewport resolution, with the highlighted element.

Every Rocket Validator customer gets this message from me. Not a bot, not a "customer success team" — just me, offering a call to see how they work and what would help. Automate everything else if you want, but talking to your customers is the part worth keeping human. #SaaS #human
Screenshot of the in-app notification for every user in Rocket Validator: "Let's jump on a call. Hi, I'm Jaime, the creator of Rocket Validator. I'd like to help you get more out of it: tell me how you work and I'll show you how to fit it into your workflow, from scheduled scans to the API or muting rules. Book a short video call, I'll be happy to answer your questions. Pick a time"

I laughed so hard at this LLM-generated image (Gemini) with a prompt for "an old-fashioned clock showing a few minutes before midnight" 😂
AI-generated image for an old wall clock showing a few minutes to 12. As the prompt specifies "a few minutes before midnight", the AI included the letter "PM" inside the clock, like 11:56 PM

I love using Logseq as my notes-taking app, for both work and learning guitar. It's great for embedding YouTube videos and taking notes as code blocks for the guitar tabs.
