   It is a nice mini-blog, it's for free and such but

   As a mini-blog, it is a nice alternative for Medium to publish and share information about programming.

   However, the community and the organization are biased toward social justice (and they are open to it). You can read its Code of Conduct, it is so vague and politically leads (I prefer a term of service because it defines fair rules for everybody). So it alienates developers that we don't care about politics in pro of people that want to talk about any other topic such as sexuality, how women are unprivileged, and such. It even mandates to use inclusive language. Good grief.

   My main complaint is the quality of the community. It is not StackOverflow (so we don't want to ask for an answer here), and most of the top topics are clickbait, such as "how to become a rockstar developer in ... days", "100 tips to become a better programmer" (and it doesn't even talk about programming).

   Technically this "mini blog" site allows us to use markdown, and it is okay. However, the whole experience is really basic. Even the template is ugly.

• What Is AI Agent Tool Calling? MCP, Function Calling, and A2A Explained (2026)

  That is the gap Arcade.dev is purpose-built to close. Unlike a routing gateway that simply proxies requests, Arcade is a full action runtime. It's a secure execution environment for production agents with per-user authorization, vaulted credentials, structured audit logs, and hosted tool execution.

  Outside PostHog, the acquisition picture did not match. Real arrivals were mostly organic Google Search.

• 🐘 Like... TypeScript for PHP? Yes. And it's not what you think

  In the previous parts of this series, we explored how PureScript acts as a quiet rewrite of the Web, offering a sanctuary of mathematical precision above JavaScript, and how its universal polymorphism allows it to target wildly different runtimes like Node.js, Erlang's BEAM, Chez Scheme, etc. - Source: dev.to / 5 days ago
