Update 2

As of August 28th, 2025, Expert LSP has been released: https://github.com/elixir-lang/expert

Although still a work in progress, the plan is for the other three LS implementations to be archived. I may try to come up with a new way to track Expert's featureset, but I would probably contribute that back to Expert as documentation.

Update

As of August 15, 2024, it's been announced that the three projects bein compared here will soon merge! See the official Elixir blog post for more details: https://elixir-lang.org/blog/2024/08/15/welcome-elixir-language-server-team/

Swift’s memberwise initializer and the extension dance

Swift's automatically provided memberwise initializer is a powerful feature. However, when an explicit initializer is present, Swift omits its memberwise initializer:

struct Person: Decodable {
  let name: String

  enum CodingKeys: CodingKey {
    case name

Anti-hype LLM reading list

Goals: Add links that are reasonable and good explanations of how stuff works. No hype and no vendor content if possible. Practical first-hand accounts of models in prod eagerly sought.

	# Download model
	export MODEL=llama-2-13b-chat.ggmlv3.q4_0.bin
