I just don’t understand - Apple decided to implement a more capable SIMD instruction set and just … didn’t document it? SIMD is hugely important in anything remotely HPC related. My first gen apple silicon laptop still favorably competes ag

This is my thought, exactly. Reading has always been a contract between the person who wrote the text and the person who’s reading it: “these are my thoughts, recorded to share with you.” When reading LLM-generated text that purports to be

Your last sentence describes my thoughts exactly. I try to incorporate Claude into my workflow, just to see what it can do, and the best I’ve ended up with is - if I had written it completely by myself from the start, I would have finished

I wish I knew more about cattle to add to the analogy but I do very much appreciate it as is.

I’ve been a longtime competitive athlete and my best deadlift was 545 lb. I’ve been in many gyms in my life and I’ve only met maybe a dozen men lifting more than say 350 or so. Expecting the “average” man to get to a 400 or even 300 lb dead

tkinter is the best kept secret in the Python std lib. Pair it with numpy and matplotlib (two external dependencies that personally I consider part of Python itself), and you’ve got 80% of an interactive scientific simulation environment.

Same here! That’s a great blog with a lot of good advice.

Hearing someone proudly describe themselves as a libertarian always reminds me of the ol’ twitter quote that goes something like “libertarians are like house cats - fiercely self-assured of their own independence, yet completely reliant on

I’d argue that in many of these instances, less is far more. I want my car to just be really good at being a car, reliably get me from A to B. A Bluetooth connection to the stereo system is nice, but I don’t need a freaking 20” phablet righ

I feel for the author. I do both mechanical and software engineering and I’m in this career(s) because I love making things and learning how to do that really well. Been having the most difficult time accepting the idea that there isn’t a g

Radiation does not work “incredibly well”, especially at the temperature range of interest. Forced convection (what every large terrestrial electronics system uses, from gaming laptops to terrestrial data centers) is orders of magnitude m

Agreed that some level of gatekeeping and some level of friction to protect quality are useful things.

I only personally know one Rust programmer (works in scientific HPC) and he’s fantastic, but in general I do get the sense that most Rust devs migrated from JS and are just now figuring out “omg strong typing and compiled code native to the

Honestly hadn’t even thought of that - easy to say “more is better, right?” or miscalculate what the dose should be.

Yea, I think this is a bit half-baked. Either the journalist doesn’t know how diabetes is treated with insulin therapy, or it’s meant for people with T2D who are only on a basal dose (unsure how common that is). There are ‘classic’ insulins

Interesting… though seems to be limited to basal insulin doses. The basal/bolus paradigm using pens or pump (both injections) can’t really go away without a ‘smart’ insulin that stays in the bloodstream, inactive, and only reacts to ch

This, 100%. I forget the specific numbers but regardless, the kinetic energy of a thing with that much mass, even moving at a very slow speed, is off the charts. Designing a bridge or protections for a bridge to survive that would at a mini

The processing capability of today’s CPU’s and GPU’s is insane . From handheld devices to data centers, the capability to manipulate absurd amounts of data in fractions of a second is everywhere. It’s not the hardware, it’s the algorithms.

As someone who takes insulin every single day and lives in mild fear of an overdose, the idea that it was once used to intentionally induce hypoglycemic comas as an “psychiatric treatment” is a terrifying concept to me.

This works really well in mechanical engineering, too. We don’t necessarily use tickets specifically, but planning out work or a design upfront with a small audience saves a lot of time and wasted effort. On some level this is just basic pr

Is this sort of thing widely known ahead of time before purchase, ie signing some T&C’s? My car is >10 years old, which feels like a lifetime right now, given the rapid pace of change in car tech (notice I didn’t say “progress”). It

Interesting, how so? I’ve had really good success with the autovectorization in gcc and the intel c compiler. Often it’s faster than my own instrinsics, though not always. One notable example though is that it seems to struggle with reducti

Interesting, in what domain? My work is in scientific computing as well (finite elements) and I usually find myself in the opposite situation: SIMD is very helpful but the added complexity of using a GPU is not worthwhile.

Which came first, the nvidia drivers, or the super-necessary local models that wrote those drivers?

Given the “blazingly fast” branding, I too would have thought this would be in stable Rust by now. However, like other commenters I assume it’s because it’s hard, not all that many users of Rust really need it, and the compiler team is smal

This article is specifically about the implementation of SIMD in Rust, not other languages.

All you're doing is passing an argument of the incorrect type to your function. The exact same thing fails to compile in C: ``` #include <stdio.h> typedef struct { int value; } Feet; typedef struct { int value; } Meters;

I couldn’t agree more. It feels “squishy” to me. The only statically typed, compiler languages I have a lot of familiarity with are Rust, C, and C++, and they all have different sort of warts. C with some sort of module system and the tooli

Forgive me - much of the article went over my head so I’m trying to understand: this article is excellently written, but I’m struggling to understand why a `Vec<u8>` wouldn’t have sufficed? And disregarding the first question, is ther
