gonna have a panic attack at the twinkle twinkle "star" not being a half-note.

I wrote this in a review I believe, but this is one of the most comprehensive introductions to a good 80% of what could be considered a high performance computing education. It's extremely well written, in the weeds, but not lost in them. If you've done heavy atomics and or locks in C or C++ or with Fortran libraries, this will help show you how rust prevents so many footguns at compile time.

Triggered by the use of 1-bit to describe a trit.

My thought has always been that the ratio of lifetime to any given sublifetime unit of time is always increasing, leading to a change in relative experience. But if you focus on the fact that a second is constant, you always have the same amount of time right now.

First project I've ever seen that made me instantly sponsor it. Then to only find out you wrote fd and hexyl and some other classics. Great work.

I love this and I'm super glad it's being developed, but I think I'd have to break my arm or hand (or have severe RSI) to really dive in. The startup cost seems high, mentally speaking.

How does this handle the machine running out of memory?

This is great, the amount of boilerplate it takes to write an iterator is a bit cumbersome right now. Looking forward to see how this fares as it moves towards stable.

Let's say you wanted to run some python code that was written and test it against some C/C++/Rust for accuracy of some sort (numerical, lexicographical, etc). In the old way you would have to fire up multiple processes to do that (like OS level processes) but now you can have your multithreaded compiled code running in threads and your multi-GIL'd interpreted code running all in one process and comparing their results in the `main` of your C/C++/Rust. That's a contrived example, but the issue was that a single GIL isn't threadsafe in and of itself. So if you're using these compiled languages as sort of python runners you couldn't multithread python interpreter execution and guarantee the code working. Also as the above comment stated, you could do hacks, but you'd double your memory allocation by needing a python and C/C++/Rust representation for everything that went back and forth.

Same w/ Rust and Python, this is really neat because now each thread could have a GIL without doing exactly what you said. The pyO3 commit to allow subinterpreters was merged 21 days ago, so this might "just work" today: https://github.com/PyO3/pyo3/pull/3446

I drove into a ditch in Costa Rica following google maps. It was the end of any fantasy of ine that they still wanted to organize the world's information. Luckily it only cost $500 or so for the privilege of finding that out for sure.

This was the big turning point for me, and I'm in my forties. Thinking that I couldn't enjoy exercise was mainly because my 'form' was so bad it literally hurt. Luckily you can get better at things, and once you do, or you reach that point where it feels good, then the discipline isn't really needed any more than folks need discipline to play their grueling video games.

The mental health limitations around flight are how you get malaysian air flight 370. Don't say anything, treat anything, work through anything involving mental health because you'll lose your license immediately. Therefore the folks with milder mental illnesses will never solo pilot a plane, and folks with serious psychopathic mental illness, especially if it appears after they begin working, will kill everyone on board.

Oddly my parents owned a bookstore, so yea I was growing up in the opposite of the GOP vision for Florida.

jarmitage is a legend (in my eyes), so I'm sure he has his own opinions, but TidalCycles (as it is now known) depends on supercollider for both Midi and Sample playback. It communicates to supercollider through the OSC protocol, so it's conceivable supercollider could/can be swapped out for another engine. As is I think the install a bunch of Haskell stuff + install an editor plugin + install supercollider is the largest blocker to getting folks started with tidal. In the pre-tidalcycles era, Tidal played samples (only afaicr) through its own Dirt sample player which was still a separate process, but included with tidal itself. Now it uses SuperDirt which depends on supercollider.

Compared to PD and max/msp, Tidal is far more focused on the pattern language and the magic that can come out of that. Any 'programming as programming' has to be done with Haskell and loaded in as its own functions. Puredata and max/msp both are full (graphical) programming environments with their own quirks and special tricks, but in a way a bit more like Supercollider in that they can speak midi and do playback inside their own engines (afaik).

As a kid I had access to that book and I got to be a pretty wicked card thrower. Haven't tried it in a while.

Incredible. I still remember 13 ghosts being the most intense game I'd seen on TRS-80. https://www.youtube.com/watch?v=ZQDqYZ2pgOs

This is akin to saying get all your trash back from the landfill before it closes.

Oddly the first issue I came across today was folks being confused about this. I haven't gotten to the bottom of where the code is now, but this go library was messing up len == 0 vs nility and someone forked it to fix it: https://github.com/algorithmiaio/mapstructure/pull/1 It may not be a common bug but that doesn't make it less of a pitfall.

the ability to cast nil as a zero length array means there's no difference between a function that returns a zero length array and a function that returns nil (assuming some casting process takes place). It could be a subtle and annoying bug to track down the difference.

This is the most satisfying answer, but it doesn't make the implications less complex.

My fave golang slice trick is the len of an empty slice is 0, but the slice itself is == to nil, but the len of nil won't compile. Can't understand that one.

"The dream of humanoids is that they should be able to do all the things that we do, right?" "we" is a stretch here, since the speaker has never worked at any of the activities their robot can play-act at doing.

The desktop linuxes I've used would be my daily OS if it weren't for the edges. Not necessarily as sharp now as when you could break a CRT with the wrong modeline, but still bad relative to the alternative (for me macOS). I mean things like fonts, copy/paste, screen resolution, kerning, cursor acceleration, bounding boxes, full screen support, sound (and I primarily know what I'm doing with Linux Sound since the OSS days.). It's the churn that keeps the GUI tantalizing close but distant. There are happy kde and gnome users out there, heck I'm on KDE right now typing this, but all those other victories had a unity of involved 'stakeholders' (AWS, millions of ISPs, Android, etc) and the focus in desktop OSes is famously nebulous (or at a minimum splintered along multiple axes). Still things like PopOS give me hope for the future. Also I'm a 2 spaces after a period ghost from the late 1900s whose opinion isn't worth much.

You’ll be ok. I’ve been institutionalized many times and I’ve never even tried to start a business. Take care of yourself and shield yourself from the liars who profit from your belief in their fabrications. Be well, health is a process and has nothing to do with monetary or business success, but is far more valuable.

As someone who graduated into our country investing in air bases, cafeterias, supply chains, bullets, diesel and barracks in 2 occupied countries instead of this, I'd say thanking the president is in order.

The concern over startup energy is like saying we can't have internal combustion engines until the engine can start itself with gasoline. Turns out we've gotten along fine starting cars with electricity for about 100 years, including a long while where we had to hand crank them ourselves. Surplus is just a matter of runtime once you're getting more than you put in to maintain it.

wouldn't folks just join the military if this was their dream?
