If Amazon had terminated their listings without any cause or even because of competition agreements it probably would have been legal. Since it was in direct compliance with an illegal demand and Amazon stated as such they probably doomed themselves. Judges tend to look very poorly on large companies ramrodding the small guys. The small business wasn't prepared to spend $50k+ just initiating the process and went on with their business model.
One problem with that approach is that those long distance trips tend to coincide with everybody else in America taking those long distance trips (Thanksgiving, Fourth of July, end of school year) with surge prices for rentals as a result.
To put in context the remark that Ellison made
about lying to customers that is referenced in the top rated comment, this happened during a sales cycle to Bank of America in 1981-1983 timeframe (can’t remember exact year).
It’s featured in the 2006 Bloomberg Ellison video bio (link below) and it’s where Ellison wanted to exaggerate the number of Oracle programmers/engineers from 3 to 15. I have no sympathy for Bank of America, but that’s because they’re a bank who screws over regular ppl somewhat directly. Oracle has the decently to put a few middlemen in the process.

NOTE: I’m a liberal arts major who was hired straight out of college during the GFC of 2008 for a non-technical role by Oracle and then later they trained me and put me in an engineering slot (!) so I’ll always be in their debt/totally bias. The above story I thought was somewhat relevant / interesting nonetheless + I hate Bank of America and now bank at USAA.

I assume the simple way to avoid it would be to not create an assignment in the system ready for grades to be entered until you actually have grades to enter. While a way to put an assignment in a state that it doesn't affect overall grades would be good and annoying if missing, it doesn't seem like something that's impossible to work around.
Personally, I rather just not read paywalled articles, or I would have paid if the publication is high quality enough.

Using a workaround to circumvent the paywall seems too shady, because if the contents are worth reading, they should be worth paying the asking price.
> As an aside, ignorant physics question, does the half-life of something decrease with heat?

Short answer: No. Definitely not in a Volcano.

Long Answer:

Decay rates are ultimately determined by the subatomic structure of the nucleus. This is why different chemicals, and different isotopes of said chemicals, will decay differently. A lone neutron will decay after about 15 minutes (which is a long time in subatomic scales), however, the two neutrons in (4/2)He will happily stick around forever.

So melting a material won't have any impact on the structure of the nucleus, you're just disassociating the intramolecular bonds; same goes for turning said material into a gas.

If you were to raise the temperature high enough, and we're talking sun-like (not the measly 5000k that you get on the surface, I mean like 27-million degrees you find in the core), then you'll actually start stripping and fusing nuclei, which will at that point change (but not necessarily decrease) the radioactive rates of whatever material you started with.

Of course it’s true that people and cars are finite, but that doesn’t mean that new roads are satisfying existing demands. In fact, the term in economics is “induced demand.” Building more roads around a city often won’t decrease traffic in the city, it will just make more people commute to the city from further away.

Traffic can’t go to infinity, it can only go to 100%, and yes, if you paved every square inch, then traffic would go to 100% in areas where lots of people want to be, like people driving into urban centers for work.

Oh, absolutely: it's part of my sylabus, everyone is aware. Perhaps a bit paradoxically, it makes giving final grades much easier. If a student gets a bad grade, it's because they ignored all opportunities for improvement and I fail them with some sadness, but no regret.

That’s not an uncommon view, I’m sure, but I suspect if the externalities of driving an automobile with a single person in it were internalized, so each driver paid the full cost of driving, you and a lot of people would change your minds and instead invest in some (comparably vastly cheaper) noise-canceling headphones for the train/bus.
It seems to me that a "niche" doesn't form unless there's a demand for it. I've seen enough indie games with "adult" themes like That Dragon Cancer and Papers Please to lead me to believe somebody is looking for games like that.
The pipe is an operator overload. That said, while I wouldn't exactly call it idiomatic, it's not entirely unheard of in third party libraries. RxCpp (https://github.com/ReactiveX/RxCpp), the C++ ReactiveX library, makes use of a similarly overloaded pipe operator, for example.

Personally, I think I'd be more apt to use the "functional" style.
It also goes on to say "European systems need more switches and other gear to maintain the same level of reliability" so European utilities probably just spend their way to better reliability (burying power lines is one way to do that)

> We need 30 years of nuclear fission before we can sustain fusion.

Not sure where that comes from. I don't think we'll have competitive fusion in the next 50 years. Sure, people who talk about ITER draw (quite optimistic) plans for when we'll be able to get more from the fusion reaction than what energy we pump in, but they forget to mention that's not the end of the story. Fusion may be clean, but it's terribly inefficient. In the Sun, fusion generates about the same amount of energy per liter as a liter of warm chicken soup releases to the ambient environment [1]. The Sun is huge, so overall the amount of generated energy is huge, but on Earth a power plant that has the same power density as the Sun would need to have a volume of 4 billion m3 to be similar to a typical fission power plant (1GW). That's 4 cubes of 1 square kilometers each. And don't bet on us getting to that efficiency in the next 20-30 years. So, sorry for the bad news, but no, we won't have viable fusion power plants in the foreseeable future.

> In short, the crypto hate is a reaction to the crypto hype.

Actually, as someone who was very interested in Bitcoin in the early days of 2011-2012, I disagree. If anything, the hate on HN was even greater back then, way before Bitcoin became hyped. So many people were convinced it was a pyramid scheme. It was clear to anyone familiar with the Bitcoin community back then that there were a lot of highly technical, talented people, and very few scammers. But most of HN reflexively despised Bitcoin.

In fact, Bitcoin on HN is actually a lot less hated now, which tells me it has little to do with the hype, and that something else was going on.

Bear in mind that I disassociated myself from Bitcoin once the scammers, con-men, and get-rich-quick types infiltrated the community around 2013 and 2014. But even back in 2011, there was a very high number of HNers who seemed personally affronted by the very idea that money was a social agreement. They seemed to believe that money was some kind of official, government activity, end of story. And that anyone who believed otherwise was an evil heretic, to be ridiculed.

> I have very little sympathy for people who profited from the hype, delivered approximately nothing of use to the rest of the world, and now have a sad that there are consequences.

This I agree with 100%.
Yep, that's the one... Only the Acland St / Barkly St intersection is gone. It's enough that most vehicles don't head down the street.

They could easily expand the pedestrian section further up the street - and I'd like to see it too, but smaller measured steps will probably be more sustainable until parking gets "solved".

> state channels (ETH’s version of Lightning), but it is unclear whether main-chain issued ERC20 type tokens will be portable to this environment.

The Raiden project is the closest thing to Lightning, was recently deployed to the main chain, and explicitly supports any ERC20 token.

The article says Plasma is dead because...Peter Todd, a Bitcoin dev, claims they had a similar idea and rejected it? Meanwhile, on Ethereum a bunch of teams are actively working on it and the Loom project has a version up and running.

The article asks why if proof of stake is so great, didn't Ethereum just start with that? Because proof of stake had widely-recognized security flaws (like "nothing-at-stake"), and it took years of research to fix them all.

The entire article is of similar quality.
For me, just about 18 hours with parity on a fairly new i7 and fairly fast (200mbps) net and NVMe disks. Haven't repeated enough to be sure, but I can't figure out how to replicate the "weeks" argument I keep hearing.

That's only really true for income taxes; we're in the top 10 for VAT, way above average for gas taxes, high energy taxes, etc. If you look at the net personal average tax rate, we're close to Norway, Luxembourg and France, except when you live with less than €10k/year, every marginal euro taken for taxes hurts quite a bit more.

Thanks a lot! It would be cool to have some of it get used! I've been trying to get all of it online. Right now there is not really anything coherent ready to put up yet - a smattering of Jupyter demos using/explaining aspects of the code. this keeps getting triaged for another day, and yet I keep seeing bezier and B-spline stuff get popular on here.

It's a huge swath of messy python with the first stuff dating back to 2012. I used Piegl and Tiller's book C++ converted to python for the underlying B-spline stuff. (needed to implement anyway in order to compute constraints and objectives for custom auto-diff solver...)
Then convert the spline control points into an overloaded automatic differentiation type for use in construction of the basic curve solver. That we at least have documented publicly in the journal of CAGD here: https://www.sciencedirect.com/science/article/abs/pii/S01678...

The stuff above made it easy to be really flexible about what constraints are used in any given curve. (Or surface, but I did not go there for direct optimization.)

Next comes... all the interval arithmetic and relational constraint logic to pare down the design space to only the feasible domain on the front end. It's going to take a while to clean up the code and tell the story better.

The trick for kayaks is that my professor had me focus on industrial applications. -Designing offshore supply vessels, that sort of thing.
I could work with you to try and re-tool a bit to see what we could get. I can't make promises though! I am swamped with a new baby and various other job related things at the moment.

Nevertheless it should be pretty easy to get started, since a kayak is a sort of generalized canoe, which is the first hull form anybody generates. The outstanding issue is that I've not yet worked on developable constraints!
(Actually I've been tooling up to bring some discrete differential geometry to bare on this) The issue here is that nonlinear B-spline surface optimization direct is expensive. See, e.g. https://www.cs.cmu.edu/~kmcrane/
Developable triangle meshes and other such papers. Cool stuff. Of course the shape representation is different.
There are the old directrix techniques as well.

The problem isn't giving final grades.

Some teachers are more equal than others. In all seriousness US labor unions have been infamous for going blatantly being gerontocracy on the ground they have been paying dues for the longest.

Given stuff like 'contractually they are bound to lay off multiple newer teachers before they lay off the one a year from retirement'.

While screwing over your loyal members isn't good treating the new ones like dirt is also a death spiral move - I know that everyone in High School who worked a job with a union hated it - the consensus was that they were paying a cut and openly screwed over in favor of everyone else.
Similar experience with geth on an m5.large EC2 instance and 500G SSD.

The SSD vs. hard disk distinction is key. I ran into the "it will literally never complete" issue trying to sync to an external HD on my home MBP - I ran it for about a week and it didn't work. Tried parity as well, same result. Once I decided I'd just rent a big SSD from Amazon I had no problem.

Given the 500 square miles of Los Angeles and the 4 million people population, that's about a 60' by 60' plot of land per person. Given that doesn't include roads, highways, industrial or commercial zoning, and that people will group in housing (families), I think that's fairly dense for the type of housing which is currently in place, which is homes homes with yards.

It's not dense relative to other types of metro areas, but I think it's probably fairly dense for single level housing in an industrialized nation.

My point wasn't to imply that Southern California was very densely housed, but that there may not be a huge amount of unutilized land left to build high density housing one, at least not enough to really change the dynamics. And once the conversation shifts from just what to build and where to also who to displace to build it, it's an much harder conversation.

I could be entirely wrong, I don't live in LA, but my impression every time I visit is that there's not a lot of unused land, even if the land that is used isn't used efficiently (population density wise). If that's true, it's not just a NIMBY situation (even if it might have traditionally been one), as it's also a "don't displace historical group X that's been living in this area for decades" situation (whether entirely accurate or not).

> Your skills are more important than the prestige of your school.

I'd disagree slightly. All of Mark Zuckerberg's college roommates are billionaires or half-billionaires - mostly because they were his roommates. Obviously they brought their own skills to the table but there existed other people in the world at that time with those skills too. These specific people got to be in the rocket ship when it was on the ground, because they were at Harvard. Otherwise, they'd (probably) only have very successful careers, instead of their current wealth and status.

I think having a "prestige" school on your resume opens some doors far more easily.

There are other ways to do subshells than using the same syntax, just that the Fish developers never did it, maybe because it's not requested enough. I think it's still the most annoying thing about Fish, and the most convincing reason to switch away again. I frequently drop into bash to do

(cd subdirectory && command --that might.fail) && run --command-in-original-dir --only-if-subshell-succeeded

... and expect to still be in the original dir when it's done. Any solution in Fish using "&& cd -" at the end of a block AFTER a maybe-failing command is just wrong, and there seriously isn't any way except saving and restoring $PWD every time you want subshell functionality, or using "; cd -" and manually saving the $status, which is equally as frustrating.

> if the contents are worth reading, they should be worth paying the asking price

How about if the facts the article communicates are worth knowing, but their treatment in the article isn't worth the (digital) paper it was printed on?

I can see your argument applying to editorials, but not-so-much to raw journalism.
Nothing in the _world_ has intrinsic value. Obviously, this an opinion, but I do believe it has strong epistemological backing. An easy overview of the opinion by wired: https://www.wired.com/story/bitcoin-has-no-intrinsic-value-n..., a 1970s era discussion by a historian economist: https://fee.org/articles/the-fallacy-of-intrinsic-value/, and a deep dive the theory itself: https://mises.org/library/introduction-value-theory

Now i'm not expecting nor wanting to get into a debate about the theory of value. I do not expect to be able to win, nor do I want to, but I do hope some doubt is cast into the proposition:

> Matches have a value, you light them and they produce a certain amount of energy

Matches have a _utility_, not necessarily a value. Additionally, compute is _also_ just "burning resources", only its electricity instead of potassium chlorate. Arguably a more fungible form.

> regardless of the fact that it has no debt instruments, lacks liquidity and is completely unregulated and prone to theft.

Only one of the four accusations stands up to any critical thought - which is that it is "completely unregulated". If that is the core of your argument against distributed, trustless currency, then that argument applies equally to all pre Federal Reserve transactions the world over, and I'm not sure what the implied problem is.

The best quote from the first and most approachable of the links above:

> All new mediums of exchange spawn skepticism, and should. For much of the 19th century, paper money was held in ill repute because it seemed so ephemeral and detached from value that could be easily recognized: land, gold, size of armies.
