As I am setting up my new machine, I came across this error when emacs tried to use rust-analyzer
error: Unknown binary 'rust-analyzer' in official toolchain 'stable-x86_64-apple-darwin'. As mentioned in this SO question, which rust-analyzer did not show any error.1
Luckily, the same SO question also had the solution
I needed to explicitly install it via rustup component add rust-analyzer
Luckily, the comment in the accepted answer also explained why which works.

When refactoring code to make API call to Gemini, I learnt how to format raw strings in rust.
fn main() { let var1 = "test1"; let formatted = format!(r#"var1 is: {}"#, var1); println!("{}", formatted); } This gives output as : var1 is: test1
If you want { in the output, then it needs to be escaped with additional { like:
fn main() { let var1 = "test1"; let formatted = format!

It is very important that secrets are stored in environment variables during the runtime.
During the development, it makes sense to use .env file. In my last project, there were probably 40+ variables in the .env. Although that project was in RoR the idea of .env itself is not new.
But for me, using .env with rust is new.
For my current (self) assignment, I needed to store an API Key.

Finally, my Macbook Pro is back!
As part of fixing, they put OS X Yosemite on it. 😭
Practically nothing worked. For some reason, Apple ID login also did not work.
I checked on another machine, username/password was indeed correct.
There was no option to upgrade to macOS Monterey (last supported version on this hardware) from the App Store either.
App store listed macOS Sonoma, which I knew wasn’t supported, but tried it anyway. As expected, it said “Not supported” (Duh!)
Finally, resorted to Internet Discovery.
It offered to install macOS Monterey, as expected.
All is well.
(It took some time, downloading etc. But otherwise pretty uneventful)
Today was my last day at Sage (I joined Lockstep, which was acquired by Sage) I spent a little over two years working with the wonderful engineering team there. I learnt a lot from everyone on the team, and made some new friends (I knew one person before I joined) during my stay.
Most of the team was junior to me (in terms of number of years of experience.) But as I worked with them, I noticed that every single one of them were exceptional engineers.

I had tried switching to tmux for local shell sessions in past, but never truly understood why I might need it.
I extensively used tmux for remote sessions. But why might I need it locally ?
Then slowly I stopped using tmux and switched to wezterm which provided multiple tabs.
Fast forward several years later.
Recently I came across Zellij. I decided to give it a go.
When I had tried tmux it took some time to get used to the keybinding.

At work, I need to load test new framework I had deployed.
Usually, I work with QA team. They use JMeter (with Azure Load test) for such task.
But today, the QA person was busy with other tasks, and I didn’t want to get blocked.
Since I am learning rust, (nu-shell is built in rust) I remembered that it may be possible to run parallel requests in nu-shell.
and it is!

My Macbook Pro won’t boot anymore :(
I was watching some Youtube videos in the evening, and then at night, it
just became unresponsive.
Over the next few days, I tried various options.
Booted from external USB. Worked!
Tried Internet Recovery.
Turns out the SSD is recognised, but can’t be fixed/formatted/erased.
Looks like a hardware issue.
Clippy is a linter for Rust programming language.
If you are annoyed by the compiler (shouting at telling you how your code is wrong), wait till you install and use clippy 😄
Jokes apart, why I want to use clippy is it tells us about idiomatic rust and can autofix issues (if we tell it to do so)
Couple of fun facts I discovered :
First search result for clippy is not what I was looking for 😄 till I searched for rust clippy clippy can not be installed via cargo install (As I tried initially) (As with rest of the rust ecosystem) there was a helpful error message with solution 😇 error: Clippy is no longer available via crates.

Earlier I wrote about various utilities written in rust. Nu shell is one of the most important of them (It is an entire shell after all, not just single utility)
Installing Turns out I had installed nu-shell earlier, but via macports
and I had forgotten about macports (and nu shell)
Mysterious upgrade failure (Or so I thought) When I installed nu-shell via brew I got the latest version, but nu kept invoking older version.
