I don't have a lot of personal experience dealing with addiction in either myself or others, but TFA lays out to me a pretty compelling claim that addiction is a developmental disorder. The current mainstream belief of addiction as dis

That's a great paper. I've tangled with the line fill buffer issue before, along with other hidden limits such as infinity fabric limits on AMD systems. It's one of the first big disppointments when you start doing high perfo

Impressive memory bandwidth! I feel like x86 offerings often fall down so flat in this area. Even when theoretical memory bandwidth is provided, there are often other significant limitations that prevent its use. I've run into this per

At least for x86, there's an incredible wealth of architectural details out there, both from the vendors themselves and from people who have worked tirelessly to characterize them. Along the lines of another comment on this post, part

This is probably the right place to grumble about the fact that it took Intel until ~2020 to stop selling chips that still don't have AVX/AVX2 in them, a solid decade and change after the tech was introduced. According to the stea

You are able to buy now, but not pay until 30 days later, paying no interest unless paid in full. Which means YOU earn interest on your money during that period...

The evidence produced is definitely addressing a different argument than the one he actually starts with. Comparing ancient empires to modern living standards is nonsensical for the purposes of determining if plunder was the basis for empir

It might be helpful if you explain why you think it's stupid instead of writing a one sentence dismissal. Otherwise why make a comment?

Yes, but this concern is orthogonal to calling convention. If the parent function does anything to the object, it will be in cache already. If it does not, but loads the fields to register, the parent will take the cache miss instead of the

Surprisingly, this is one of the value propositions of Costco! Of course, the first thing they're known for is letting you buy comically huge volumes of everyday items. But one of the reasons that they actually have a cult following is

It's not really a fractal in the sense that a fractal is a mathematical object, and a coastline lives in the real world. As your ruler gets smaller, it also becomes impossible to define what even is the coastline anymore - is it the we

Calculus deals with things that are sufficiently smooth on a small scale, and thus converges. For example, approximating a circle with smoother and smoother polygons. The length of those polygons will converge to the circumference of the ci

I think in our modern age, a lot of people can be surprised at just how fast the CPU is relative to GPU. Slower, yes, but compiled SIMD-enabled CPU code is bloody fast. I've seen people on HN claiming "just put it on the GPU and b

Agreed. This is a very odd rant against smart pointers that is essentially a rant against the strawman. The most relevant line is this: "to most other languages you are simply passing the address of a buffer". That's true! An

Exactly. Outside of the actual merits of the feature being flamed, someone confidently presenting such an opinion without caveat is unlikely to be worth having a reasonable discussion with.

On the contrary: while to you the other things you spend your time with might be more interesting, for the rest of us the means through which you have acquired all of this free time... is by far more interesting and useful. Care to share?

Agreed. I really appreciate their deep dives into uArch - their article on the Zen4's front and back end answered so many questions for me..

Almost all of these exploits are due to the out-of-order/speculative execution.. which is incredibly complicated. There is no reason to believe that an out of order architecture that has not been hardened is any better at defense here

The article is spot on about SIMD. Often, if you can write your code in exactly the specific form that you would if you were using intrinsics, the compiler will go ahead and SIMDify for you. But you have essentially a 0% chance of writing i

Someone claims that a human can run a 5 minute mile. To prove it true, you just need to show a human who can run that fast. To provide it fast, you have to accumulate incontrovertible evidence that it's simply beyond us...

Out of curiosity, do you have any examples of workloads that you have shifted wholesale to the GPU instead of AVX?

I think the words being look for here are analogy rather than essential. The essence of a bicycle is not a motorcycle with a human motor. However, that is a very good analogy for what a bicycle is.

Exactly this - The language is big and getting bigger, and so is the standard library. But this is true of almost any popular language! By the metric people are applying to C++ here, there is no one on earth who "knows Java", whic

Whenever linear RGB / gamma discussions come up, you know there's going to be a lot of folks going on about how frustrating it is that the default for most apps is to do their blending/filters/etc in gamma space (as TFA
