I never knew that about exhaust velocity. So as propellant mass efficiency goes up linearly, power use goes up exponentially? does that make fast interstellar travel impossible?

Japan gets more flak because it's physical and historical isolation plus high cultural homogeneity have resulted in unique societal quirks.

Going to western Europe feels like the US. Going to Japan from the west still feels like traveling the world once did. Its unique culture is appreciated worldwide, even from closest neighbors.

They had smartphones almost a decade before we did. They had high speed rail before anyone else . Manga and anime are now worldwide, but they were born in Japan. Kawaii has spread to south Korea and to some extent the west, but it was born in Japan. Hanko instead of signatures is unique. Bowing. Onsen. Sumo. Vending machines. Much of the food... There's countless examples.

We're should be celebrating human uniqueness, Japan is a special place

This seems to imply millennials are lazy. They're the most educated generation in US history, and at the same time, the poorest in at least 60 years.

COVID relief funds are only paying them more than their normal wage because they got paid so badly to begin with. All older generations have averages incomes significantly higher than what COVID unemployment pays. And that's despite Millennials being more educated than all of these prior generations.

It's finally given many of them the freedom and agency to choose their jobs rather than take the first thing they can find to avoid going broke. Many of these people looking for jobs were also the first laid off at the beginning of the pandemic. Why should we feel bad for companies that treated these people as disposable?

There's not a "worker shortage". Companies are complaining that they have to raise wages to attract talent because workers are shopping around and getting counter offers.

This is not unprecedented. The same phenomenon happened after the Spanish flu, and was arguably a big factor in the collapse of the fuedal system during the black death.

Wide scale destruction of jobs followed by increased demand gives workers leverage. You have a huge group of people not afraid of being jobless because they already have been.

We have to remember that 600k people are dead too. A decent chunk of available labor is gone forever.

COVID restrictions blocking employers from hiring foreign labor is also a factor. There's increased competition for American workers because it's harder to import cheap labor

Is that not true? Google and Oracle had a 10 year multi billion dollar legal fight over ~20 lines of code identical between Android and JVM.

A non rich individual has basically zero chance of challenging GitHub on these blatant violations, and they know it.

At any rate, it's not even clear to me if me publishing code written with copilot (or even with a random tool that will wget from github) puts the blame on the toolmaker or on me.

It really depends on the license, which GitHub apparently doesn't care about at all.

It's not outrage bait. The thing reproduces GPL licensed code verbatim.

This is the crux of copilot. When I saw it copying RSA keys I knew, it's overtrained.

Most of the comments are waxing about philosophical possibilities of copilot copying GPL.

Reality is clear in the case, it's copy pasting thousands of characters of GPL code with no modifications. Copyright violation clear as day

I don't really welcome our new corporate overlords, but why does anyone give a shit what Chinese govt thinks?

They're hilariously corrupt, natavist, and frankly crazy. To the point that you can't even admit Taiwan has been an independent country for half a century without them having a mental breakdown.

And have fun if you're a Muslim minority. They're busy hitlering everyone who isn't ethnically pure enough.

Chinese govt is a joke. I guess AMD didn't bring enough cash suitcases on their last visit

Copper is already expensive enough to have an impressive recycling rate. Over 90% last time I heard

Friendly reminder that the #1 reason for impacted ear wax is people sticking their fingers in there.

Ear canal skin grows outwards. If you never stick your finger in your ear, eventually everything will work it's way out.

The people spending time and money jamming stuff in their ears are like the women who used to wash out their hoo-ha's in the 50's

I think he meant to waffle about kimberlite pipes, diamond mines.

Otherwise no that sounds crazy

You're not even allowed to tell people about the fee on a page soliciting donations. Google and Apple are a monopoly. We need antitrust.

This should be at top. I miss pfsense, but they been the trailer trash of routers for a while now

I am. Cars are a big hobby for me, a big part of my life. Chevy is the only company not going out of their way to make things too complex and locked down to repair yourself.

Chevy is the only manufacturer with viable aftermarket parts for many varieties of auto and boat racing. Like yeah, you see supras and Hondas and stuff at the strip on weekends. But serious racing is running Chevy Small Block derivatives.

Tech bros lament the death of open platforms for their hobbies, like the continuing lockdown of phones. The same thing is happening with cars.

Thankfully Chevy has proved you can have a modern competitive car that meets emissions standards using 60's engine layouts that are easy to modify and repair.

And pushrod engines aren't that bad. Overhead cam adds a huge amount of weight and bulk to the engine. This is the only reason Chevy is still able to fit 6 liter engines into their small sports cars. Everyone else has transitioned to small turbo engines because DOHC takes up so much space.

And the modern Chevy V8's shut off half their cylinders when you're not using them so they don't waste tons of fuel either

For some reason they've really only been widely available in the US in the past few years.

I think it's cheap energy. In places like Japan they've been using heat pumps a long time

Heat pump water heaters mentioned in the article are better for efficiency. They typically use half the energy of a normal water heater.

And they cool the air around them, so if you live in a hot area they save more.

It's not different :)

Water can absorb enormous amount of energy. And releases huge amounts as it evaporates. And the lake is in contact with massive land surface that also absorbs ton of energy.

The deeper parts of Seneca lake are isothermal with regional ground temperature, so there's clearly no problem with heat dissipation

Hear me out, I don't buy this. NY would have never approved operating a power plant that did such damage to the lake.

Notice they mentioned "surface temperature". Many lakes are naturally stratified in summer. Especially lakes deep for their size. https://en.m.wikipedia.org/wiki/Lake_stratification

Indeed, Seneca lake is very deep, and naturally thermally stratified in summer:

Because of Seneca Lake's great depth its temperature remains a near-constant 39 °F (4 °C).[3] In summer the top 10 to 15 feet (3.0 to 4.6 m) warms to 70–80 °F (21–27 °C)

https://en.m.wikipedia.org/wiki/Seneca_Lake_(New_York)

I think crypto mining is a huge waste of energy. But this article has an ax to grind. A simpler explanation for warm surface temps is a warmer than usual summer.

Indeed, NY state has had two major heat waves already this year

Oh definitely. Rust was the first to be trendy enough to get traction though. I'm not bashing previous attempts to replace c.

Dependency management, packaging, and testing are what really made Rust take off. The best of any language I've used.

We voyaged the world in wooden boats for a long time too. It was absurdly laborious and dangerous.

Hahaha. I lived there and we called it that all the time. More common among friends living on south side tho

Chiraq isn't an insult, that's what people living there call it.

I'm convinced Chicago is unfixable. The south side has been so poor for so long it's basically a third world country.

The best solution is a planned dismantlement of the irredeemable parts of the city. And relocate those people somewhere they stand a chance of finding a job.

When rust belt manufacturing died Chicago had no jobs for a million people. And in 60 years the situation hasn't changed much

Kiwi Farms exists to make fun of people with mental illness. It's the same as a site that makes fun of people with cancer. Totally digusting place

C is a terrible language. It's portable assembly. I've done some small OSS projects in C and as soon as I realized Rust was stable enough I tossed them and rewrote in Rust.

Rust feels like a modern language, like Go or C#. C is barely better than FORTRAN.

I'm massively more productive in Rust and I don't have to worry about a million ways of causing UB or memory bugs.

Everything from dependency management to testing to cross compiling are dreamy in Rust compared to C.

We didn't know what electricity was 300 years ago. And the best way to get around was riding on the backs of other animals.

We're maybe 70 years away from being a multi planet species if technology keeps advancing at the same rate.

We just need better ways to get into space. If the Sabre program works out or we figure out fusion power we'll be ready to roll in 20.

Or we could figure out self replicating robots. Nature has been doing it a billion years so we already know it's possible.

Or, just create a robot species in our image to explore for us. And hope they keep their meaty parents around and happy

There's multiple paths for humans to get off the planet. Out of the solar system, maybe not. But it's damn hard to predict farther than 100 years into the future

Possibly not. Most asteroids are far out, and the giant planets tend to knock them our way. Mercury is also a smaller target.

Earths atmosphere protects us from all but the biggest rocks. Micrometer impacts on Mercury are a real danger, but that's also true in space/moon/mars

Hahahaha.

Maybe it's coming time for a restriction on HN article topics? Political gunk is getting worse than that time I signed up for a Trump newsletter

Please do it! We did fine for thousands of years without targeted advertising. Technology is being abused like a dystopian sci fi novel to improve bottom lines. It's wholly unnecessary.

Clickbait reply: Zstd is a huge advance in compression, but not for reasons you think.

Yes it's fast, yes it has a pretty good compression ratio. But it's greatest strength is streaming feature.

It supports sending chunks of data individually decodable but compressed with knowledge of previous state. Why is this so important?

Because small string compression is crap. For data < few kb, simple dictionary substitution does better than zlib.

But with Zstd streaming, compression ratio rises as more data is sent. Game changer for slow channels.

Imagine messenging over 200 bits/sec channel. You need each message to be individually decompressible. But these are short strings so ratio is terrible.

Enter Zstd. If message delivery is reliable, doable with retries + FEC, you make all messages part of a stream. By the time you've sent a couple hundred, youre getting great compression on tiny strings.

This is huge for constrained channels like NASA rover communications and more mundane IoT networks with low rates and power limitations.

You can get even bigger savings with the knowledge of what the other peer has seen in bidirectional channels. You simply compress the data from the other end mixed with yours. If you have equal data in both directions, combining the prior state this way gets you to good compression ratio terriroty twice as fast.

I have no FB connections with those who wrote Zstd, but i believe this feature was a priority design criteria. Maybe for their balloons or some IoT project, who knows. Either way its a huge advance in data compression.

Its roughly equivalent to how we stream video as diffs from last frame interspersed with keyframes. But for general purpose rather than video.

I don't know anyone currently taking advantage of such property. And you will need to strip out frame headers to make good savings. But a fun project for any of you nerds working on low data rate channels.
