Other people having an opinion and creating their own software project to implement it is not “forcing” anyone to do anything. The inverse would be no one is allowed to create any projects that you don’t personally agree with.

It’s an abstraction because it literally hides knowledge in service of presenting a more a more cohesive API to the human. It requires less knowledge at the front end, which is when people are being bombarded with a ton of new things to lea

What's wrong with this approach specifically? Go does it this way. Rust does it this way. Elixir does it this way. It reduces the toil in setting up and using projects in those ecosystems substantially. It unifies community effort behi

Abstraction. Not having to know all the innards (or even names) of each until you want to. It's all there if you want to, but stuff like uv (or cargo, or go's toolset) greatly simplifies 3 scenarios in particular: starting a new p

People build stuff informally all the time, and that stuff very often works fine. Rich Hickey digs into this in some detail. It's not that types or formal methods or rigorous specs or automated tests (or whatever else - pick your forma

As someone outside those communities, could you elaborate?

I have worked Elixir/Erlang and Rust a lot, and I agree. Rust in particular gives ownership semantics to threaded/blocking/locking code, which I often times find _much_ easier to understand than a series of messages sent betw

SQLite has an explicitly stated policy on this: "The intent of the developers is to support SQLite through the year 2050." https://www.sqlite.org/lts.html People talk about SQLite's reliability but they shoul

This has nothing to do with math or number crunching on the BEAM. This has nothing to do with mutation. This has nothing to do with performance. This kind of process and function-local static single-assignment code is all over the place in

Rebinding is not mutation. This seems pedantic but is an important distinction. None of the semantics of the runtime are changed. The data remains immutable. You probably know this. However, for the benefit of readers who may be less famili

Full disclosure: I started with Erlang, I get paid to work with Elixir every day, I love Erlang still. Why someone might like Elixir: - slightly less crufty stdlib for a lot of the basic stuff (though we still use the Erlang stdlib all

This is all well and good that we developers have opinions on whether Go compiles faster than Rust or whatever, but the real question is: which is faster for your users?

I've never taken a lick of CS in a formal setting, and I feel like that's increasingly common as programming has broadened its employment base. Most of the people I work with haven't done formal CS, either. Consequently I&#x2

This is not exactly what you’re referencing but I bring it up to show just how complicated things can be: Minnesota recently ruled that you do not have the right to use deadly force if you have the opportunity to escape. And this is the cru

He literally gives extensive primary source citations to show that the originators of OOP presented this class-domain correspondence as the correct way to think about and do OOP. Bjarne Stroustrup is not just some random guy.

They may be referring to uvx: https://docs.astral.sh/uv/guides/tools/ Or it could be something else, not sure.

by asa400 1y ago
You can, however, use uv for this, e.g., `uvx yt-dlp` works like it would in pipx. https://docs.astral.sh/uv/guides/tools/

How was SQLite used in that scenario? What was the architecture?

by asa400 1y ago
This is correct, and one of the things I tell anybody who is considering using SQLite to watch out for. The busy timeout and deferred write transactions interact in a really non intuitive way, and you have to use BEGIN IMMEDIATE for any tra

I've written hobby-quality clients and I think the answer is yes. First, you're dealing with input from a server you don't control, and second, you're doing quite a bit of interaction with the filesystem. It's hard

Yeah, I guess it depends on what you want. Clojure is not to everyone's taste, I can respect that. It's a decent option if you have to target the JVM.
