   I know the author has other goals (a desire to learn/practice kubernetes, and keep host their blog the same way as the other services they manage), but I'd like to point out here that if your end goal is a blog which auto-deploys

   Hey HN, author here. Inspired by this great strange loop talk by Alan Shreve [0], which discusses a non-standard use for code coverage reports, I wrote a blog post about using kcov [1] and pycobertura [2] as a tool to help start understandi

   This was really neat, but I wish the author went into similar detail for the auto white balance step.

   I may have overlooked some things, but I made a quick PR[0] just to see what this would look like using a Vec<u8>. Feel free to close if you prefer the original. [0]: https://github.com/tomarrell/rasp-ws2812b&#x2F

   Thanks for sharing. One question about the code, why does the LedPanel struct use a String as a buffer rather than using a Vec<u8>? edit - I think I see the reason now. Using a string made it easy to print the u8 as a string of bits,

   These [0] two [1] sections of the GNU Bash man pages were very useful. I also found that this tutorial [2] provided a useful perspective. I spent a small amount of time looking through the bash-completion [3] project as well as the git bash

   I did come across this work by clap while doing research for this post. The major difference in strategy is that clap is generating completion scripts in Bash, while shell_completion is a library which helps writing completion scripts in Ru

    Your characterizations are spot on. One major potential improvement for the shell_completion crate is to provide a higher level API for use by completion script writers. This will of course make writing completion scripts easier, but it wil

    It is not possible for a shell to know how to perform completions for every binary on a users machine. Shell completion scripts define the auto-completion for each specific binary, so for autocomplete to work (well) it needs to be supported

    Author here. This blog post is the result of my puzzling over how auto-complete works in the shell, and subsequently whether shell completion scripts could be written in Rust. It also introduces a new Rust crate, shell_completion[0], which

    You can listen to the DHCP traffic caused by the button press (the button is sleeping until pressed, so every press causes DHCP traffic) and use that to trigger any action you'd like. I wrote a simple utility[0] to do just that. The lo

    As I was thinking about an improved user interface for the shell, it seemed like at some point you'd hit the limit of what is reasonable given the current split implementation between terminal emulator and shell. Do you think you'

    Thanks for sharing, your posts are very well written. I really like the idea of syntax highlighting before the user presses enter. Any reason you are writing your own posix parser and readline implementation, rather than using existing Rust

    I'm not confident enough to say this for sure, but I think you are off base. I created a demo in the Rust playground [0] which shows that there is no implicit environment variable expansion. Also, the source for `std::process:Command`

    I'd second the recommendation for rustyline. I played around with it a bit while reviewing the rush[0] project, another shell implemented in Rust for learning purposes. [0]: https://github.com/psinghal20/rush
