You don't see, I don't see, but I believe they saw.

Well, my experience was modern mode is way more responsive, and I've convinced at least 5 friends on sight.

It's actually the opposite, modern mode uses gpu for compositing, classic modes uses cpu, and any gpu would beat cpu handily in that task including integrated ones.

Unless, you didn't install the correct driver and used standard vga driver, or like in a vm which doesn't provide gpu acceleration.

If this is true, I think the nobel prize committee would happily make an exception for them.

Thanks for the update, after reading that, and the fact the patent was dated 2021, my faith is lost.

I don't really have an explanation other than they're simply crazy.

let me simplify that for you: how does a superconductor not violate one of the laws of thermodynamics?

Are you living in the fairy land? in the real world, Academic fraud is a thing.

All valid points but just below that comment someone asked if he/she was reading the new paper (apparently there's an older paper), he/she didn't respond/haven't responded yet.

It's a bit hard to break it to you, but Santa isn't real.

Does the thought that there might be some guy in a garage 5 miles from you replicating this baffle you?

The sheer size of the sample stuns me.

There's no valid evidence of that.

Some random notes of Rust and Go

Koiwai — Wed, 11 May 2022 09:05:42 +0000

I'm recently involved in a project using both Rust and Go, wrote some notes about them, from a user's perspective, posted here:

It's kinda hard to remember the difference between rust for and go for, especially when you wrote them side by side.

1 main desktop

1 router, you'd probably argue this doesn't count, but my router is debian running on consumer computer hardware, with custom vpn and routing.

1 file server, this one is not strictly at home, since it's located in my company's server room for the bandwidth, but I mainly use it at home over Internet.

1 gaming laptop, connected to TV.

1 lightweight laptop in EDC bag.

3 mining rigs.

ipad and android tablet.

For the record I said manageable not great or perfect.

I don't normally care about the author's gender, but I'd argue assuming that is a man is a honest mistake, as long as women in the tech industry is still a minority. Do you really need to go that far? I think that shows how fragile you're.

While any modern operating system is the living counter point, so far it's manageable.

The fibonacci should use an array/slice for storage instead of a map(hashmap).

That Option type is using pointer, not foremetioned Zero, &nil and nil are different things.
