rust was originally conceived of as a language to replace C++ in Firefox

17 / 111

  • statically typed

  • compiled

  • no runtime

  • small memory footprint

  • memory safety guarantees

18 / 111

rust is a programming language that wants to empower all developers to be systems developers.

10 tips

(that may or may not work for you but will almost definitely make you a better developer advocate)

23 / 111

tip 1

don't rewrite your software in rust

24 / 111

tip 1

don't completely rewrite your software in rust

25 / 111

complete rewrites are very often unsuccessful

26 / 111

A complex system that works is invariably found to have evovled from a simple system that worked. A complex system designed from scratch never works and cannot be patched up to make it work. You have to start over with a simple system.

bashing other languages makes everyone look bad

tip 7 be prepared for things to change

problem:

our node service logs are full of runtime errors

parsing them is slow

i just fully expected to rust my way into 50% perf over js. sometimes i forget that v8 is pretty darn fast.

You are never dedicated to something you have complete confidence in. No one is fanatically shouting that the sun is going to rise tomorrow. They know it's going to rise tomorrow. When people are fanatically dedicated to political or religious faiths or any other kinds of dogmas or goals, it's always because these dogmas or goals are in doubt.

i thought i'd be selling rust because of its speed

there's a learning curve to making rust go fast

making rust correct is the default!

the safest program is one that doesn't compile

tip 8 be prepared for things to stay the same

80 / 111

boring code is my favorite code

81 / 111

just because you started using rust doesn't mean everything will change

in fact, it's better if it doesn't!

tip 10 learning curves are a blessing in disguise

99 / 111

this is the really fun part about learning new things. i still have the patience to do any number of silly things

100 / 111

learning something new can be energizing

learning something new can be energizing

even if (or maybe because!) it is hard

If you’re going to repair a motorcycle, an adequate supply of gumption is the first and most important tool. If you haven’t got that you might as well gather up all the other tools and put them away, because they won’t do you any good.
