@martindonadieu Courage Martin! Out of curiosity, was this your first test? I’ve read that since the spermatogenesis cycle takes about 72 to 74 days, a single test is never really considered conclusive. Doctors usually wait for a second one 3 months later.

@NETGEAR @NetgearFrance you should check out this app made by @valeriansaliou to monitor your mobile router's status and consumption right from the macOS menu bar. It works remarkably well and it's quite useful :) https://t.co/0PeKTtBmBk

learned about function overloads in typescript (ad-hoc polymorphism) https://t.co/D9xkkM6keH

Most important lesson I learned years ago from watching my friends succeed:

Staying focused mainly on one project for years is rare.

Finding motivation even when it gets boring is a skill.

It’s why I look at all this AI panic from a distance.

Endurance is the real moat.

[Julien Le Coupanec @LeCoupa]

@alexd thought about this too a few days ago

[Julien Le Coupanec @LeCoupa]

@alexd playing with https://t.co/nWW15SuSJH, one of the best pieces of engineering I have seen since a long time :)

Differences between Virality & Network Effect.

- Virality: Current users bring new users, lowering acquisition cost (Tupperware, ChatGPT, Dropbox…).

- Network Effect: New users bring more value to current users, increasing retention (WhatsApp, Visa & Mastercard, GitHub…).

Just deployed Beszel for server monitoring.

It’s a minimalist alternative to Netdata.

- Lightweight: Tiny resource footprint (~6MB RAM).

- UI/UX First: Modern, polished dashboard. Zero clutter.

- Centralized: One self-hosted hub for all VPS.

Migrated from MySQL to Postgres in every project.

What made me switch:

- Rich Types: Native UUIDs, Arrays & JSONB eliminate messy workarounds.

- Safety: Strict data integrity & transactional DDL (no broken migrations).

- Future-proof: Built-in AI (pgvector) & Geo (PostGIS).

Just played around with @getdokploy and their multi-server management via Docker Swarm. It is incredibly seamless and functional. 🐳

It adds a layer of abstraction to run multiple instances I should have used earlier. And their UX / interfaces are the bests.
