Sam talking about #GPT7 in 2021 That's cute but that knowledge he mentions belongs to everyone, not to private corps' internal agenda. We are not ready for what's coming in 2027. I didn't want to believe what many analysts said last 2 years... but it's becoming real.

Worktrees dont work well for me on big projects. I prefer having many agents working on the same milestone together in the same branch, in coordination and aware of each other's work

The Microsoft sentence that broke all our tooling: “While TypeScript 7.0 is here, it does not ship with an API.” Svelte, Astro, Vue Volar, Angular compiler, MDX, and basically any AST-based generators/codegen Let's hope 7.1 brings all they need #TypeScript #TypeScript7

for your routine use Auto mode + Claude Opus 5.5 reasoning will be automatic I think, but the important part is that you create a good plan with high/extra/max reasoning, without had-holding it too much: let it take decisions on best practices and design choices. iterate later after reviewing the 📸

My current workflow: - Plan your idea with Claude Opus 5.5 extra or max - Review the backlog md tasks and docs it creates - Configure a routine that will be your coding agent taking tasks every 1h if there are no pending changes. Ask it to take screenshots of important UI changes. - Enjoy life ☕️

This is a must watch for any #Claude Opus 5.5 dev www.youtube.com/watch?v=51Eb... I confirm what this guy says: it's constantly doing good work & if you pair it with tools like Backlog MD + Claude Routines to plan + code your ideas... it becomes even better, keeping record of every product decision

Higgsfield plugin for Blender is definitely better at modeling than GPT alone but it is incredibly expensive. This Gequa was created from a refernce 2D image (official artwork). First one: Higgsfield prompt, second: created procedurally with primitives with GTP6 #PokemonWindsWaves #Blender #Pokemon

M5 Ultra with 256GB of RAM at around 12k... €12k of #Apple hardware doesn't buy you €12k worth of AI capability relative to the cloud. If a subscription is 200/month, 12k is 5 years of subscriptions before you've merely matched the hardware purchase, and by that time your machine is outdated...

The paradox is that as an AI-boosted developer I have never worked so much in my life like I am doing in the last months. Since we can do more things at the same time, and people expect results faster.. I see myself doing 4 or 5 things in parallel all the time. That or I might be developing ADHD 😆

After working heavily with custom agent skills, I realized those docs become outdated really quickly, while MCP server updates can roll out instantly. Use skills for repetitive reusable prompts, workflows, guidance, and MCPs for executable tooling and external systems.

A new programming language? in 2026? with this economy? github.com/vercel-labs/... I believe that the next programming language is just structured Markdown and plain english. We won't be looking at the generated code the same way we aren't looking at compiled code. And that's good and bad.

What slows down your scroll on large lists might not be the DOM, or JS, or your framework... it might be CSS! backdrop-filter is one of the few CSS properties that has to run per-frame during scroll because the captured pixels behind the element change every frame. It can saturate the compositor.

I am thinking about creating a CLI companion for setup-planning-workflow, that would connect to a small sqlite db. Maybe a small MCP server using just Bun and bun sqlite. Agents would have a centralized way to coordinate, better than using .md files.

This is a months project but I got a working Coolify alternative in just a weekend. It involved a strong planning phase with ADRs, PRDs, and implementation checkpoints, all documented in the repo. Coolify is cool, but I wanted something more opinionated that has a builtin docker registry + graphana

I agree. we should be more careful and start using tools like direnv + .envrc to load env vars from files external to the workspace, since they will live in the shell session instead. Agents can still print them, that's still a caveat.

Javi Aguilar @itsjavi.com · 10/05/2026
Coding agents will read your .env files and there's nothing you can do about it, unless you put them outside your workspace. Never store sensitive keys in your workspace .env files (e.g. production API keys or database connections).
