Whenever you write a succinct example or a metaphor to try to explain in a few words a complicated concept, someone will nitpick small details of your construction, thus focusing on the form and missing the spirit! Forget if "i<n&qu

Take this example: for (i=0;i<n;i++) A[i]=0; for (i=0;i<n;i++) B[i]=0; It can be conveniently transformed into this: for (i=0;i<n;i++) A[i]=B[i]=0; They are exactly equivalent except if the first loop

Expecting a piece of code to be compiled to a precise sequence of machine instructions is exactly what you should not do with high-level languages like C++. Their task is exactly to abstract the machine away. They give you the guarantee tha

> this is just structs. Yes. And structs are just bytes. Levels of abstractions don't do anything the underlying levels don't already do, they just give you means to express your intent in a clearer form.

But there are "cubic bazillions" of possible URLs that are being requested. Even if they boil down to "only" some millions actual commits, their rendered HTMLs are all different.

Tangent question: what about NPU performance? I always read about CPU vs GPU, but nobody talks about NPUs; I don't even know if llama supports them. Why do phones and laptops get equipped with NPUs if there's no use for them?

This is for iPhones only. Do I assume correctly that the issue is solved for Android, instead?

You might have misunderstood TFA. No push for trig reform, just a consideration on what internal representation is optimal in code. Imagine it like someone suggesting (understandably) that you express memory sizes in hex: no push to make ev

Sure, it's your choice where to put your precious time. Exactly like Sheldon, you prefer not to dedicate any energy to question a judgment you have decided a priori . And like him, you might be missing out on some good stuff.

Even worse: cover letters, presentation letters, even CVs themselves are routinely read by AI, at least in the screening phase.

I can't help wondering why so many new languages provide two separate mechanisms to define mutable and immutable variables. I see a value in defaulting to immutable unless explicitly stated, like in Rust. But having to choose between t

Sometimes yes, sometimes an equilibrium is finally reached. The fact that we see more equilibrium than extinction is purely "survivor's bias".
