McIntyre or Griffiths' QM might be useful.

I had the same experience; that's mostly what I'm referencing. Trying to use things like The Hacker's Dictionary (largely in-jokes, bad jargon, and obnoxious circular definitions) to clear it up made the problem worse. I get that it's just a humor book, but still.

Yeah, it's not like any programmers have ever come up with bizzare and useless names for abstractions.

At least they've made a new competitor to the linguistic mockery that is Carls Jr.

Having "quantum computing" in the title makes this genuine clickbait when the body lacks any explanation of what a state is or what a ket is. Energy or momentum or spin states are rarely (never, in reality) just numbers.

You made no attempt to explain what the two different states in a single ket mean: hint, it's superposition. Never provided even a trivial justification for why normalization is important; where is the actual physics?

Using Rust here is also quite pointless when you're just doing linear algebra... where is the actual benefit over Python or even Haskell?

You've written a very cute and inefficient math library, but calling this QC is just false advertising.

It's basically a 90-year-old pun involving splitting the word "bracket" into "bra" and "ket".

There's a really easy solution here: just use a device with a super shitty battery and only charge it once a day. Then, hide the cable.

Now there's an incentive for them to learn electrical engineering.

Turkey is doing almost the exact same atrocities today under Erdogan that they did in the 1920s under Ataturk.

jacquesm's really disagreeing with the person above you, probably just replied to the wrong comment.

Still counts as error!

Sounds like Rust has come pretty far.

Just type "undefined behavior" here. I'm sure you have the time.

The second and third paragraphs of the above comment are bound to age poorly.

Out him. You won't.

Probably the exhaust/escape typo.

Where's the privacy amendment again? Asking for a friend.

Arrays are vectors.

Adjusted for $ per Mbps-month, Coloradans under the Comcast monopoly pay ~100x what you do.

The brilliant part is how quickly Comcast makes back the money spent on cables laid to apartment complexes and projects. They can wire up 20-1000 apartments with copper coax and distribution boxes for something like $50,000 and have the infra and labor paid off in under a year. After that first year, the business is essentially a money printer - no incentive to innovate or rewire neighborhoods when you have no competition.

Since the cable internet standards haven't required new copper (DOCSIS 1->2->3.0->3.1) in over a decade, Comcast can simply upgrade one or two $100 boxes per complex, raise their prices and provide "faster" service while spending nothing on actual R&D.

They can outsource customer support to Southeast Asia, standards to CableLabs, modems to nearly any company in China, and even piracy detection to random firms like IP-Echelon. Don't forget - Comcast owns an enormous number of film studios and production companies. If there's anything approaching the digital media panopticon, it's Comcast.

I don't know if there's a better-positioned software company in the ISP business.

demonising -> demonetizing

no, dispersion.

dang, please change the link to this: https://www.greencarcongress.com/2019/09/201090911-gatech.ht...

Much more information and a link to the actual paper: https://www.nature.com/articles/s41563-019-0472-7

Many Chinese suppliers are already operating at or below the $100/kWh mark.

This comment is meaningless without clarifying

- which chemistry is being discussed

- what these percentages represent: weight, volume, or cost

There is no lithium-ion battery (NMC/NCA) where Li corresponds to 79% of any of those.

Awesome! Sorry if my comment came across as dismissive.

There's no difference between this and any other fashion choice like car styling, clothing, shoes, house painting, hairstyling, or furniture.

Whatever "technological" or "UX" advantage marketed via blogposts like this is simply a veneer over the standard human competitive strategy: 'what I have is more fashionable than what you have, so pay me.'

One might even imagine they were engineered to be optimally efficient at freeway driving speeds! :D

This is a great comment, but it's in the wrong place. The OP is about using Rust/C to compose network and packet handling software; using Fortran there would be completely pointless. There is no easy gain to be found from vectorization in networking.

Higher voltage alone does not magically give you longer sustained maximum power.

Electricity moves itself. You apply power on one end and it flows down the line at about the speed of light. There is literally nothing (other than superconductors) with lower marginal cost per joule transmitted than wire.

Wires never blow a tire, head gasket, or transmission - and in fact they cannot even crash into and kill people on the highway. They're just long pieces of copper or steel tied to a tower. How convenient!

If you instead compare the fixed costs, as you seem wont to do, you'll find that HV (500 kV) transmission lines and towers capable of carrying several gigawatts [1] continuously have substantially lower initial and lifetime costs per Joule-kilometre than oil pipelines, rail, trucks, tankers, or anything else that has to move oil.
