please read the article first. this criticism is addressed.

All or most of the ssds used in this study are used as a cache in front of hdds, so take results with a grain of salt.

They're in the wrong time zone to compete...

Some of us are on mobile...

I bet $500 USD it doesn't become bigger than the bay area in the next 10 years.

Just use signed ints. Signed integer underflow is undefined behavior so it can't happen /s

You mean like this? https://www.instapainting.com/ai-painter

As someone who works in the application layer, the recommendation to have a fast failover to tcp from udp seems silly. Shouldn't the recommendation be to keep packet sizes below 1280?

He's one of the few people in the world with a more nuanced understanding of blockchains than either "it will male bankers obsolete" or "it's useless nerd money", and that writes about it publicly.

If he was satoshi he would just sign a message with the genesis block's private key saying so. He wouldn't announce that he's going to move an early coin on the bbc. It's simultaneously the most convincing proof and the easiest proof to do.

In my eyes, he's a fraud until he does it.

Now if only there were a way to mathematically prove it was a Stradivarius...

Haha I can't even imagine the hubris necessary to claim that one would rather be homeless to do another interview at a technology company.

This post helps me sympathize with the angry SF-ians angry at all the techies.

It's a 16-bit version of Salsa20, which is far less secure. Proof: this project. I have no clue what possessed the author to do this.

Stop hand-rolling crypto, people! Ransomware needs security too. :(

AVX2 usage reduces clock frequency for a millisecond. It's suspicious (?) that performance numbers were given in terms of clock cycles and not wall clock time. It might have even worse system performance impact for small messages, where one takes the AVX2 clock frequency hit for little gain.

Maybe universities should consider paying more to compete with the tech companies. It's a free market and whatnot. If the price goes up, you gotta pay more. Complaining about the price going up isn't exactly productive.

Since when was demanding a cut when people use your platform to run their business worthy of scorn?

To whom will they walk?

This is entirely correct. The article doesn't fix the original reason why the "CSS turing machine" wasn't actually a turing machine. It doesn't "crank its own tape", so to speak.

Layout in a web browser, which includes CSS styling, is implemented as just a top down + bottom up tree traversal. 2 tree traversals do not a turing machine make.

Maybe an analogy will help. I like the multiplier mentioned in the grandparent. Consider the multiplication circuit. I hope you agree that a multiplication circuit is not turing complete. However, if you apply a "pump" and feed its results into one of its inputs, you can calculate the factorial of any number!

This concept can be extended to take any sequence of steps and calculate recursive functions with them. This doesn't mean a linear sequence of instructions is turing complete! The feedback is a fundamental part of what makes the system turing complete.

The headline would better read "CSS + user input which can trigger a reflow is turing complete", but that wouldn't be nearly as interesting.

In fact, if CSS _was_ turing complete, I can solve the halting problem!

Step 1) Encode a turing machine as CSS + html.

Step 2) Run CSS and layout. This is O(size of css + size of html), since it's two tree traversals.

Step 3) It halts. CSS styling is finished.

CSS is just a tree traversal. It has a lot of rules, but the structure is simple. It is not turing complete.
