As someone who worked on V8 for some years, I can assure that Web bloat is not due to frame pointers.

Virgil doesn't use frame pointers. If you don't have dynamic stack allocation, the frame of a given function has a fixed size can be found with a simple (binary-search) table lookup. Virgil's technique uses an additional page

I would have believed this before the M1, but now I think fixed-width instructions are great for parallel decode, so there's a real threat now which is attributable to RISC.

I agree that the line is pretty thin, but would draw it as: fixed-width versus variable-width. I think the M? line of Apple CPUs, with extremely-wide parallel decode, has been a game changer. The performance per watt is really off the chart

This is an extremely dark take that is certainly not true in most CS and EE programs. Students change advisors all the time and there are plenty of internal mechanisms to report misconduct and blow the whistle. The fact that the student fel

I work on programming languages and systems (virtual machines). A key thing with a systems programming language is that you need to be able to do things at the machine level. Here's a talk I gave a year ago about it: https:/&#x2F

Joel of course hits the nail on the head about the two major things that cause abstractions to fall apart: performance and bugs (or debugging). In programming languages we talk about abstractions all the time--PL of course is all about abst

Don't mistake noise for action. One thing corrupt people love to do is make loud sounds that they are fighting corruption when they are not doing that, instead having their palms greased by people doing that exact kind of corruption.

In college I had a PC with a 100Mhz bus. One day I was defragging the hard disk-- as one did in those days --and by chance had the PC case cover off and also the FM radio on. As I swept past 100Mhz I picked up the unmistakable KKSSHH CHKS

Watts are a rate (energy/time), you don't need to divide them by time again.

I don't know why you're being downvoted; I completely agree with this. It's hard to put your head into the mindset of a beginner after it's been in the deep end of the pool for so long. Stuff needs to make sense now an

Interesting! Given the small amount of power relative to the total amount in the tides (I've seen an estimate of 3.7TW), this doesn't make a big difference to the Earth/Moon gravitational system, but I'm curious how this

I have found that HN sentiment (not just in the case of my comment above) does not suffer criticism of markets well.

The only optimists these days are humanists. Environmentalists generally think the planet is kind of screwed.

The answer is that birth rate needs to decline and the human population needs to level off and then also decline to sustainable levels. We're in overshoot right now and no amount of economic development (read: growth) is going to fix t

Are you referring to the weak references or to interior pointers? What I've been surprised by over the years it that a simplified, perhaps slightly broken version of a language comes to Wasm first, then as features expand, more of the

+1 to implementing a Rust interpreter. You can skip the entire middle and backend of the compiler, and if the program doesn't do much, this will be faster than any other solution. The Virgil compiler includes an interpreter for the ent

It kind of doesn't matter when the median attention span is microseconds. What shames people is lies they told in the past coming back to bite them in the ass. But the public forgets the past, so when lies come back to bite people, the

The problem is right there in the article--incentives. There are no consequences for lying, for telling obvious untruths. No one is embarrassed or ashamed of being a liar. You just have to keep doubling down forever, and even in the face of
