Compiler Tools Engineer - Jobs - Careers at Apple Apply for a Compiler Tools Engineer job at Apple. Read about the role and find out if it’s right for you.

My team at Apple is currently hiring for a role that focuses on compiler tools and infrastructure. If you’re interested in this opportunity, please take a look at the job posting here: jobs.apple.com/en-us/detail... #llvm #swiftlang

When people ask me about my job:

You know how sometimes you get irrationally furious with inanimate objects. Like when a cable gets tangled and you’re in a hurry. But the cable doesn’t have free will, it was you that tangled it. But still, you’re furious with the cable.

It’s like that.

I feel like this is better if you read the image alt text first.

Swift.org Swift is a general-purpose programming language built using a modern approach to safety, performance, and software design patterns.

Swift SDKs for WebAssembly are now available on swift.org for 6.2 and `main` development snapshots!

Huge announcement for me personally, this is something I could only dream of when almost 7 years ago I joined a few volunteers maintaining a patchset for Wasm support

The first rule of grey area club is it isn't clear if you're allowed to talk about grey area club.

I think this quote is mostly wrong and in general an unfortunate exemplar or the problem I’m talking about.

ah, but at least they're left neatly upright, unlike these shotgunned beers left behind by our local American youths

Original paper here, very readable and worth your time: pic.plover.com/knuth-GOTO.pdf

One thing not in there is often that 3% causing a problem is not where the hot path is supposed to be (you have a performance bug). But advice is the same. Find where your program is taking time, then fix it.

The sooner you know where that code is the better, because that can guide to to making sure that’s fast.

This also help you catch problems before you've written so much code that fixing it is going to take ages.

A screenshot of an old computer science paper. It has been OCRd but is clearly a high quality scan of a printout. There is no doubt that the grail of effi- ciency leads to abuse. Programmers waste enormous amounts of time thinking about, or worrying about, the speed of noncritical parts of their programs, and these attempts at efficieney actually have a strong negative impact when debugging and maintenance are considered. We should forget about small efficiencies, say about 97% of the time: pre- mature optimization is the root of all evil. Yet we should not pass up our opportuni- ties in that critical 3%. A good programmer will not be lulled into complacency by such reasoning, he will be wise to look carefully at the critical code; but only after that code has been identified. It is often a mistake to make a priori judgments about what parts of a program are really critical, since the universal experience of programmers who have been using measurement tools has been that their intuitive guesses fail. After work- ing with such tools for seven years, I've be- come convinced that all compilers written from now on should be designed to provide all programmers with feedback indicating what parts of their programs are costing the most; indeed, this feedback should be supplied automatically unless it has been specifically turned off.

Here's the quote in context. It's good advice! But it's clear about how you absolutely need to spend time on that 3%.

Key is to get your project into a state where you can continuously identify the 3% whenever you add new code.

misunderstanding the "premature optimization is the root of all evil" quote to mean "wait until you're done before thinking about performance” is a huge problem for the programming profession

you missed the footnote that all statues need to have been officers in the confederacy

#Playground macro and "swift play" idea for code exploration in Swift Hi everyone, I’d like to share an idea to help provide a new way of exploring, exercising and playing with code in Swift. Inspired by the Playgrounds features in Xcode and the Swift Playground app – ...

What if playgrounds, but on the command line… an idea for a "swift play" command from @chrismiles@mastodon.social
