Keeping an open mind, sharing what's on my mind. @ThinkingElixir, Thinking Elixir podcast. @brainlid.bsky.social

Excited to share the new CodeFlow course for individuals and teams learning Elixir! Coming from OOP, Elixir can be jarring, make the mental shift faster and love the process! @elixirlang #elixirlang @ThinkingElixir

[ThinkingElixir @ThinkingElixir]

Launching new CodeFlow course! Covers branching logic, looping, and error handling. See how pattern matching, immutability and functional programming impact the basic structures of how we write Elixir code. @elixirlang #elixirlang https://t.co/13GCyhRwbT

@kacemmmmmm @danielbergholz Here's a link to the LiveView component hot-swap config change: https://t.co/TewOk7TNm6

[Mark Ericksen @brainlid]

@kacemmmmmm @danielbergholz A three line config change in dev.exs and you get the same thing.

[Mark Ericksen @brainlid]

@josevalim The way I successfully use multiple agents at the same time: one is researching a problem in code base A, another is implementing a plan in code base B (like a library), another triaging a PR, a 4th might be developing a plan for one of the projects. I can’t do that all day.

[Mark Ericksen @brainlid]

@evanplaice At the same time, changing your SSH server to a non-standard port *significantly* reduces the brute forces attempts. Defense in depth… defense in depth.

[Mark Ericksen @brainlid]

Is it just me? Or does it feel like the safest way to protect yourself from JavaScript and Python supply chain attacks is to just not use them? #ElixirLang

[Mark Ericksen @brainlid]

@jpcarver Haha! I have great success with Phoenix LiveView and small, targeted JS hooks to libraries when needed and custom JS otherwise. Little to no exposure and a highly reactive, advanced UX that’s easy to use and maintain.

[Mark Ericksen @brainlid]

@potibas Part of the problem with JavaScript is there is no rich standard library. You have to bring in all of these dependencies to do basic stuff that is just part of the standard lib in the beam. So things like left pad have a reason to exist.

[Mark Ericksen @brainlid]

@potibas Yes, and no. Attackers are going for broadest reach, which is JavaScript and Python. Then there’s the tendency in both communities to use a lot of dependencies. That means exponential transient dependencies for your project. This become much harder ecosystems to protect.
