So weird: when you have developed so much #Rust recently that other imperative, OO-style languages feel like #ScriptingLanguage's (and no, this is not a compliment😉).

And don't you dare to assign aliases to other objects in those languages! It just looks and feels...wrong! Is it mutable? Is is not? Does it get cloned? Oh my what happens here?!😲 What...a thread!?😱

Nice, I've done some improvements regarding csv-diff's diff API:
https://gitlab.com/janriemer/csv-diff/-/merge_requests/9

So now, you don't have to wrap your bytes or String in a `Cursor` anymore. It is done automatically for you through a new trait.

Fun fact: this wouldn't even be a breaking change, if csv-diff wasn't still in alpha, because `Cursor`, `File` etc. still work as before, no change needed for user code.💪

Please keep in mind that this is _not_ released yet as a new version.

#TIL that you can disallow certain types in your #Rust code with #Clippy (since 1.55):

https://nnethercote.github.io/perf-book/linting.html#disallowing-types

This is useful, if you e.g. want to use a faster HashMap (e.g. from ahash) and not the std HashMap.

Wow, this looks amazing! 😍

Seeing all these new #Rust tools for #WebDev popping up recently (e.g. #SWC, #ParcelCSS, ...), I've come to the following thought:
There are many MANY web developers out there. What if those web developers suddenly get interested in Rust?

Rust be like 🚀

Why Electron is a Necessary Evil - by Federico Terzi:

No, #Electron is not always bad! Bad performing apps are caused by bad development practices, not _necessarily_ the technology used.

Want to see a well performing Electron app? Look at #VSCode!

Oops, turns out you can now diff 1 million rows of #CSV in only 400ms.🚀

All I had to do was to use ahash::AHashMap instead of std HashMap. ¯\_(ツ)_/¯

Yay, I fixed the bug!🎉
It wasn't a concurrency bug in the traditional sense (it's #Rust after all ¯\_(ツ)_/¯), but rather a code path that was sometimes executed and sometimes not, depending on whether the other thread had a chance to run or not.

New plan: release this within 2021 (as alpha)!😁 🤞
