That 'cost gap' is completely artificial and supported solely by price-fixing. Remember when LCD panels only dropped in price a few cents a year despite being in tons and tons of products? That was price fixing. The same thing had occurred with RAM in the years before LCD. And it was the same manufacturers involved. This time around, the story is the same. A commodity product that costs almost nothing to produce yet somehow magically never drops in price by anything but the most marginal of amounts. When those manufacturers got busted for price-fixing it only took a couple years before the price of an LCD panel dropped to a quarter of what it was previously, and SSDs will drop even faster.

WD might expect the price-fixing will continue for several more years, though. The corrupt South Korean administration dropped their investigation into price-fixing in the NAND market several months back. I don't know what impact that will have on the general international effort to prove the collusion that seems so obvious.

I just want a 20TB SSD for $500. It's 2017 and no, that's not too much to ask. They're friggin parallel grids of NAND gates with a bunch of multiplexor/demultiplexors bolted on. All photolithography. I don't need them to be those tiny little M.2 sticks, go ahead and give me one in a friggin 5.25" case. At this point they've gone about a mile past where I got fed up with this crap.
Well, I think even in a zero-inflation or even deflationary world we could imagine ways a government could still take money from citizens and give it to businesses.

Ask HN: /.well-known/techstack
Does anyone know of anything like the above .well-known URI, where a company can provide details as to what they're using to run systems in their technology departments / companies?

I feel a lot of push back would likely be security related.

But my follow-up question would be: For someone who is really determined to hack you, aren't there plenty of other channels by which said hacker could obtain this information? The first thing that comes to mind is Job Postings. If your company has never hired anyone except Haskell engineers, how likely is it that you're running NodeJS on the server-side? Also, I'm not extremely familiar with all the caveats, but I've certainly read about how hackers can obtain details about what OS a web server is running on simply by analyzing the TCP traffic.

So maybe a related question would be, how much of your public-facing stack can you realistically expect to hide from outsiders? Knowing this could help me understand why we don't have a "/.well-known/techstack" defined, and likely never will.
How dare you be clever... don't you know that if you make the very very smart people and or the mods feel less smart you will get smacked down on HN?

Or maybe it was your foolish statements of a personal nature cause that's not scientifically, rigorously provable, cause you know, personal experiences are invalid! Why... well the very very smart people know more than you!

This kind of skepticism would have been perfectly acceptable had the Wright Brothers wrote three pages of guesswork and napkin math instead of actually building a plane.
Just as a thought experiment, could the promotion of these "hyperloop" projects be a clever political ploy to misdirect/divert attention and prevent a viable high speed rail network from being built?

Elon's main business is electric cars and (one of) Branson's is airlines. So a reasonable competitor to both is fast and cheap(er) public transport along a major travel corridor in the USA.

This means that by promoting this alternative to high speed rail as faster, cheaper, better, they are undermining public support for a real project, which could mean its end.
If we're looking at Bitcoin as a proportion of black-market transactions, I have no doubt that is correct. But the more interesting question to me is what percentage of Bitcoin transactions are black market, especially if we exclude speculation?
And if you heard Chomsky he describes how growing up there were beer parties in US when Paris fell to the Nazis.

Those things was quickly swept under the rug later, and not talked about much. Also the involvement of American companies in supporting the Nazi effort including Ford and IBM and probably others.

I grew up hearing about Nazis. For the Soviet Union it was _the_ big war, a war of survival basically. Both of my grandfathers fought in the war. One drove them all the way to Berlin. Got wounded by them. I also heard stories from teachers about the horrible atrocities they've experienced. One jarring one was how their Jewish childhood friend was raped, dismembered and buried in the backyard by German soldiers. They watched through the fence in the back of the garden hiding in the bushes.

That is why it is grating to hear everyone use "Nazis" like a joke. "You are such a Nazi", "Everyone who doesn't agree with my political views is a Nazi". "The store clerk is a fascist cause they made me wait too long", etc.

Has there been a recent uptick in Yemeni immigrants to the U.S.? Almost every day for the last few months I’ve seen Yemeni women in NYC wearing full niqabs, which I’d never seen here before this year.

Three years after this rally, Pearl Harbor happens, which results in the US entering into the already-running World War II.

Virtually all people of Japanese ancestry are forcibly relocated from the West Coast and incarcerated in internment camps - around 115,000 people, 62% of which were US citizens. https://en.wikipedia.org/wiki/Internment_of_Japanese_America...

At the same time, "the government examined the cases of German nationals individually, and detained relatively few [11,000 out of the 1.2 Million born in Germany and 5 Million with two German parents]. To a much lesser extent, some ethnic German US citizens were classified as suspect after due process and also detained." https://en.wikipedia.org/wiki/Internment_of_German_Americans

Of the 695,000 ethnic Italians in the US at the time, only 1,881 nationals were detained. https://en.wikipedia.org/wiki/Internment_of_Italian_American...

The justification of rounding up all ethnic Japanese into camps was "we're at war, we will do anything to protect our country". But that same logic was never applied to the Germans or Italians, even though their countries were bigger threats than Japan.

A government commission found the treatment of ethnic Japanese to have been racially motivated, and actually paid reparations to those that were interned. But even so, this practice was never made illegal.

I find this especially interesting since a certain US President seems to have some strong feelings toward certain ethnicities and religions. In the event we went to war with a country with such an ethnicity, we would probably see these camps again, because no law has made it illegal, and there is legal and military precedence for it. It's also a near-certainty that no Supreme Court will go against a President during wartime.

Here are a few more points

I think that the reason high school debate keeps going wrong is people have never figured out what its proper function in a democracy is. Instead it's been designed to function as a means of testing how intelligent and hard-working the debaters are.

Also, let's remember that we have debates only because our form of government is a democracy and so requires a well-informed public. In countries with non-democratic governments, public debate on social and political issues is generally outlawed.
I admit to not knowing anything about how either drive type is made, but if what you are saying is true, then I wonder why other big players aren't just stepping up and making their own SSDs?

If Google can make their own processing unit just for running ML, why aren't they also making their own SSDs to drastically decrease storage costs and improve storage performance?
uBlock does block Coinhive by default which is another one of these, not sure about Coinerra though.
That's fair enough, I suppose. I guess I simply distrust his motivations beyond self-aggrandizement and inflating the idea that he's somehow an ideas man, when I can't for the life of me think of anything novel he's done for literally decades.

I'm coming across like a 'crab in a bucket' here - I've nothing against the guy or his success, but I'm not for one second convinced he's 'challenging the impossible'.
While what he has done should be commended, I don't think it's fair to say that he "started from nothing". His own mother was an entrepreneur, obviously not as successful as him but come on, he went to a "prep school" for goodness sake[1].

The original Hyperloop paper quotes its design pressure as “about 1/6 the pressure of the atmosphere on Mars” [1]. Martian atmospheric pressure is “about 0.6% of Earth's mean sea level pressure” [2]. So 0.1% of Earth’s surface pressure, or a 1,000:1 pressure change.

To put that in perspective, the Boeing 787’s GEnx-2B67, the most powerful GEnx engine variant, generates a 43:1 pressure ratio [3]. To get a sense of the engineering differences between 6:1 and 1,000:1, look at NASA’s Space Power Facility [4].

The Hyperloop’s thermal issues are a hard enough problem that they alone put this in the domain of materials science. That’s the same category of problems separating us from a space elevator.

The Hyperloop always seemed like a transportation system not for this planet. The thermal issues, too, become trivial to solve on Mars: bury the tube. Mars does not appear to be too seismically active [5] and has no existing property rights to take into account [citation needed]. (The lack of water also makes steel more viable.)

I think the problem happens when you don't know the plant. I also have some trouble until I know how the plant looks when it's happy and how it changes when it's not. It's a very small difference in some cases, but if you look at it every day you just.. know after some time.

Apart from the supposedly easy one I have that is always unhappy no matter what I do. And yet it refuses to die, it only.. almost dies. For years now.
Besides the objection that government Bitcoin seizure is not impossible, consider your threat model. You arguably have less exposure to government seizure (again, questionable, to me), but you have far more exposure and less protection from more prosaic kinds of theft and fraud, which I think most of us are far more likely to encounter.
Wouldn't that make you obsolete?
To be fair, he also stands a lot to gain if Hyperloop becomes a reality.

This was one of my favorite games as a kid. Loved the whole style of it.
I've got exactly that experience.

Many languages make it problematic to keep code actually bug-free and maintainable, and Python and especially Ruby are problematic for that, while Java and Kotlin, but even C++ (with a strict style guide) are a lot nicer to work with at scale.

If you want to keep consistent APIs between modules, strict types and checked exceptions are very helpful, while with python one typo can lead to accesses being lost — which is why so many use slots nowadays, and TypedPython, and annotations. But if I do that, I might as well use Java or Kotlin, and get a better IDE.

Compared to unit tests, strict and static types are faster, compared to no testing, static types are safer.
The Math Behind Gerrymandering and Wasted Votes
Thank god the US is helping in Yemen by dropping bombs. Bombs cure diseases right?
No, in my opinion. But not because I don't think it's a promising technology announcement or a good company, but because a casual reader of articles on HN is not positioned to compete with the professional analysts.

They mentioned that they'd be hosting an event with innovation announcements months ago. Some traders would have been buying WD stock in anticipation of that event, and wagering whether or not that included MAMR, HAMR, etc, and what each of those possibilities would mean to the company outlook.

The event and the article describing the MAMR breakthrough were posted yesterday at 9:30 AM PT. Your 'window of opportunity' to respond to the article was the few moments it took to figure out which of your guesses about what they'd announce were confirmed or refuted at the event. Even then, you may have been reading it literally by eye, while your competition was parsing it with NLP, using a gigabit connection and server located near the wdc.com servers, or perhaps using ones near the stock exchange.

https://wdc.app.box.com/s/2o32m71nthf84ozbz8wlwyo59uqxb6og/f...

As a result of this preparation, concurrent with the announcement and market open, the stock 'jumped' from 84.27 to 86.22, and a somewhat remarkable volume of 917k shares were traded instead of their daily average of 144k shares, but have since moved around a bit and are gradually settling in:

https://finance.google.com/finance?q=NASDAQ:WDC

In short: you're literally 24 hours behind the real market. Don't try to play it minute by minute based on Anandtech or HN publications.

But don't let that discourage you from buying companies based on what you believe their long-term outlook to be. Or maybe do that, and just buy into mutual or index funds instead.

That's a spot-on quote that captures one of the fundamental tensions of US History. Johnson is a enigmatic figure, as he grew up experiencing this, and did great things to bring justice to people, yet had his own personal and policy failings that stand in jarring contrast.

Much of the institutional racial and policy oddities in this country stem from this form of control, which was used to make and keep slavery an institution and keep the lower classes in check. One of the rallying cries of the draft riots (that is uncomfortably close to the modern Trump-ist white nationalist rallying cry) is that slaves were valued more ($1,000 for a slave) than the Irish ($300 to avoid war service) and were on the rise, and that rise would drag down wages when freed slaves flooded New York labor markets.
Facing Down the Network That Protected Harvey Weinstein
One way is to discuss different avenues of software engineering (i.e. web, mobile applications, code that makes things display on screens vs code running in the background that makes things more efficient vs code that helps you predict stock prices, etc.) and see if any of the topics you mention lights him up one way or another?

An alternative way could be to ask him what he likes? When I taught my boss' son, I started off by understanding what interests him - turns out he loved hockey and plays it. So then I went into talking about hockey video games vs hockey statistics.

I wonder why they chose to do it the wrong way around...
Thanks a lot for the suggestion. It is very easy to say companies just need problem-solving and should not look for technologies. It might be right for freshers.

But current in situation and interviews are totally different.

1) After some experience companies expectation changes and they want you to be proficient in the requirement they have else they hire some other guy who might have experience in that area.

2) After some experience, it gets hard to find jobs. I am getting good salary in my current job but do not know how switch the job as my company is very unstable and might get bankrupt in few months.

I might be wrong but its my opinion. I do not know how to get out of this trap and switch technologies. Any help would be appreciated.
It's amazing to me that more of this hasn't taken place. With valuations being driven by total # of users, where is the due diligence to verify these claims?

Expansion joint is likely the way to do it, but I'm not aware of vacuum expansion joints of that size. Even if it's possible, it sounds very expensive to make and to maintain. Just like everything in this project.

I love their first FAQ. You don't often see a service that comes out and says "This probably isn't for you."

> Q: Will This Work On My Site?
> A: Technically yes, economically probably not.

That same answer goes on to discuss how much revenue you could actually expect from using this crypto miner: "With just 10–20 active miners on your site, you can expect a monthly revenue of about 0.3 XMR (~$29)."

It seems like in some situations, where users are incentivized to stick around and mine for a bit, this could be an effective model. It seems like there is room for improvement in tuning power consumption and fees charged. Plus, if ad blockers block miners, it's likely a non-starter... but the merits of that are a different debate.
It doesn't matter how much you spend, it matters how much you save.
Maybe the Saudis could take all the money they're spending on weapons systems and donate it to professional NGOs that will solve this crisis. And then spend the next thousand years in penitence for their crimes against the people of Yemen.

> Now suppose you are tasked with drawing 5 districts for this region.

Or, we could go with proportional representation, make it a single district, and now we can reasonably expect to get 2-3 blue reps and 2-3 red ones, handling both the districting problem and efficiency/fairness problem in one go.
The rates I'm comparing are per 10k people, so they take this into account.

It's strange that there's so much focus on district shapes, when any voting system with proportional representation would make gerrymandering pretty much ineffective.

Every voting system has its flaws, but the US system seems to have particularly few advantages.
Interesting idea. In Denver, they're partnering with our regional transportation district to evaluate a hyperloop system here. Unfortunately RTD has been completely incompetent with existing rail programs to date so there isn't much confidence in their ability to pull this off. Could potentially be designed to fail.
It's a status field, not an error code. 0 = False, 1 = True seems like the right way to do things.

It's a good thought experiment, and not without precedent.. however the main problem holding high-speed rail back in the United States is that freight trains have priority over passenger trains.

Without changing this, high-speed rail in the US will never be a reality without building an entirely separate rail network.

I had the same reaction to the comment though I don't think I disagree with you. I think it was referring to engineering as simple rather than just calling the science and even a proof of concept as being relatively simple.

Reducing the amount of steel used in a bridge or a building is part of engineering. The Concorde wasn’t just a failure to understand what level of demand the world economy could support, it was that they didn’t solve the problems necessary to make it viable at scale. In that way it was not a complete product, it was a proof of concept.

Or, another example, it is not market dynamics alone that have changed the economics of what’s feasible with transistors. It is engineering that has made them viable at a massive scale.
