There was a post on LinkedIn about how asking DeepSeek to list states of India is not answered. ¹

First of all, why would you ask such a trivial question to it , when you can just search.

We need to consider the difference between search engine and “thinking model” like DeepSeek

It is like asking Einstein help with 10th class Physics exam 😃 - while he may be able to help, his abilities are better suited for more difficult tasks.

Recently, I came re-listened to a podcast episode where they discussed about constraints.

Everyone thinks that constraints are bad.

But having some constraints may be good.

After my previous post I came across other ways to “quickly test rust code”

Obvious being rust-script

It is easy to install via cargo install rust-script (But I had it already installed. I think Espanso installed it, but not too sure)

This may be better than rustc because one can define the dependencies in the “script” itself, like :

#!/usr/bin/env rust-script
//! Dependencies can be specified in the script file itself as follows:
//!
//! ```cargo
//! [dependencies]
//! rand = "0.8.0"
//! ```

Start the file by specifying rust-script in the shebang line, so that shell knows what program to use for running this code

Recently, I needed to test try some functionality (of getting user’s home directory) ¹

Setting up a throw away project via cargo new is certainly possible but seemed overkill.

This morning, I got an email notification that polywork.com shutting down.

Polywork was a good idea.

I never updated it regularly because I was worried about such thing (it going away) But I liked the idea of putting regular “updates” and I started this microblog.

I was going thru struct Command in std::process ¹

Obviously, I tried the very first code snippet in the rust playground. There is a very convinient ▸ to run the sample code.

The code ran without any errors.

But no output 🤔

I have been using Helix as an editor, not as an IDE. One of the USP of Helix is LSP support out of the box

Recently, I’ve been programming in rust.

Helix is also written in rust.

So I think it is natural that they would support rust LSP rust-analyzer and it does.

But I wasn’t getting auto completions 😞

In rust, tests are written in the same file as the code. But I want to have the tests in a separate file.

Conventionally, only the integration tests are written in files under tests folder. ¹

I just wanted to have the unit tests in a separate file. So I created a file src/my_tests.rs and moved all the tests there.

But cargo test kept saying running 0 tests

Turns out, I’m not the only one. ²
