No, I was thinking non-uniform memory architecture, which is to say an SMP machine where the "speed" at which you can access RAM is dependent on the core or 'thread' from which you accessed it. Lack of memory uniformity was the compromise to achieve larger effective address spaces and "simple" programming.

Today on a 24/48 core dual socket server you'll see the same sorts of thing, having a core using memory on the 'other' physical chip's memory bus will impact the overall performance significantly.

In the 2000's, before multi-core chips were a thing, there were two major camps, the 'super computer' camp, and the 'cluster' camp.

The 'super computer' camp insisted on cache coherent memory between all of the cores or threads. You got these very expensive fabrics from people like cray that would snoop access to memory from the cores and send coherency messages around to insure that if someone wrote something in to memory somewhere, everyone else's L1 or L2 cache got the message to invalidate what they were holding (shoot downs). These machines are very expensive and take months to build.

The 'cluster' camp said, "We can use a network fabric and just parameterize shared memory usage." So they put together independent machines connected by a network fabric and no cache coherency protocol. If you wanted to use shared memory you could build something like memcached and wrap your access with network calls. With that architecture even if it took twice as many cores to do what you wanted to do, the price of the machine was one tenth what it was for the big SMP machine.

For something that was trivially parallellizable like internet search or serving up web sites, that was a much more cost effective way to go. When people started doing stuff that they previously used 'super computers' and big SMP machines for on these Linux clusters it became a sort of race to pull apart these problems into "shared nothing" clusters.

Elon can get things wrong. He already said after he had announced and hyped hyperloop he had to delay the white paper because it turned out his initial idea just didn't work and he had to come up with a new one.

In 2016 he said we would have full level 5 autonomy in self driving cars within two years. That means in all driving conditions a human could handle.

That seems exceedingly unlikely.

Thermal expansion is at least easy to manage if your system is kept near 0K in operation. It's only an issue when the system is turned off.
I agree the first one is the best option.
> It doesn't matter how crazy and impossible it looks, it will be done eventually (and we have plenty of examples).

Or it won't. Most companies fail, I expect most ideas do too.

> A little bit of optimism doesn't hurt. Just saying.

Yes and no. Optimism is worthwhile but realism is important too. It's cool that private companies are pursuing these ideas and I wish them all the best, but when I see people claiming that e.g. California's high speed rail is overpriced/pointless because of hyperloop then I want to scream. We shouldn't let our enthusiasm over these hyped ideas detract from implementing the more pedestrian approaches that are proven to work and address our very immediate needs.
"The engineering has never been a problem, vacuum-tube trains are an idea that's been around for centuries. [1] Removing friction and air resistance is a simple physics problem"

"simple"

Getting to Mars is a simple delta-v engineering problem. Nuclear fusion is a simple magnetic field engineering problem. Self driving cars are a simple programming problem.

Energy efficiency is not actually that important for this. Currently there are peaking power-plants that are only in use a couple of dozen hours per year which are still extremely important.

Granted, even if Methane was 100% efficiently produced your still down to 60% from burning it. However, the main advantage of Gas turbines is they are cheap when not in use. Paying even 1$/kWh 1% of the time to provide an extra 10% power in those rare cases is really not a big deal. (1$ * 0.01 * .1 adds 1/10th of a cent per kWh to average electricity prices.)

Sure, for basic day night cycle adjustments your going to want hydro or battery storage etc, but you start needing a lot of storage that's very rarely used if you want 99.99+% up-time.

PS: This of course assumes a significant oversupply on average.
The modern shift away from the classics as standard part of western education is sad, but understandable to me.

I believe it started as a reaction to the teaching rigidness and the over-reverence of classic texts by previous generations, people just got fed up. But more importantly there's now a variety of texts that explain, enhance or abridge the classics in a more approachable manner and an overabundance of new knowledge and art to explore.

However, there's still lot to earn by reading the original texts. I reread the Iliad and the Odyssey in my late twenties and I felt this fuzzy feeling of familiarity, that human nature hasn't changed that much (if at all) through the ages. Wrath, love, courage, friendship, betrayal, revenge, vanity, wisdom, ingenuity, stupidity - way too familiar.

One of my favorite parts of the Odyssey is when Odysseus' dog recognizes him. In a few words Homer describes the special bond between dogs and humans, a relationship that spans millennia and keeps strong even (more so) to this day.

"We can barely build a high-speed rail line effectively...'

There is no high-speed rail line in the United States. The nearest thing to high-speed rail is the Acela Express, which hits 240kph on 40km of track. But this is weaksauce by modern standards.
Pairing functions only work on countable sets. This is funny because Cantor is the same person who proved real numbers are uncountable, and that there is no pairing function between 1 real number and naturals, let alone 2.

>Really? Catholics, Anglicans, most "mainline" Protestant churches are doctrinally copacetic with the notion that jews, muslims and christians alike all worship the god of abraham. This was not always so, of course, but it turns out that ecumenicalism is a pretty smart idea.

Sure, but the criterion for sameness is what matters. I see this as cultural and historical sameness, not doctrinal; the doctrines of the Abrahamic religions certainly do not agree on the fundamentals.

I also don't view it as apophatic, as I acknowledge both positive and negative claims are possible. I just think it comes down to the criteria of "sameness" and so it's ultimately an ambiguous question, and one must specify what is effectively being asked. Depending on the actual question, both your answer and others can work.

Robert Whitaker says that the only people he's met who recover are the ones who stop taking their pills. Anatomy of An Epidemic is written around the premise that psychiatric medications take an episodic illness and make it chronic.

Avoiding polyunsaturated oil is a very important part of helping people with mental problems. These oils are "deodorized" during their production process, so that people don't realize they've already gone rancid.

> But having briefly used Bumble, where the women must message the guy first, I never received a message better than 'hey, hows it going?'.

To be fair, Bumble doesn't include a lot of space for you to talk about your interests. If I can't get an idea for who you are based on a picture (yes, most guys only have one), what more can I say other than introduce myself? My go-to icebreaker is "Hi! I'm Ali. I'm bad at this."

Edit: I should also note that Bumble isn't a great dating app if you also interested in same-sex relationships. Not relevant to the parent comment, but relevant to me.

> https://mises.org/blog/deflation-always-good-economy

That article is just bad. It spends a lot of time talking about reduction in prices, but the real problem with currency deflation is that it results in a reduction in wages.

If computers cost half as much as they did ten years ago meanwhile everyone is making the same amount of money, that's great. But if people are also making half as much money then it's useless, or worse than useless because then people are making less money but still have the same mortgage they took out ten years ago. Which is what happens with currency-generated deflation (as opposed to efficiency-generated consumer price deflation).

> The economic effect of money that was created out of thin air is exactly the same as that of counterfeit money — it impoverishes wealth generators.

Except that the created money can go to the government which it can spend in lieu of collecting more taxes, which would otherwise have come from "wealth generators" regardless.
But it is a hard fork, termed that way by the organization that is the custodian of the ethereum network. It is only misleading if people outside cryptocurrencies misrepresent what a hard fork means.

I wish "Black Like Me" were mandatory reading in public schools:

Black Like Me, first published in 1961, is a nonfiction book by white journalist John Howard Griffin recounting his journey in the Deep South of the United States, at a time when African-Americans lived under Racial Segregation. Griffin was a native of Dallas, Texas, who had his skin temporarily darkened to pass as a black man. He traveled for six weeks throughout the racially segregated states of Louisiana, Mississippi, Alabama, Arkansas, and Georgia to explore life from the other side of the color line.

It's short and fascinating.

You are so spot on target that it's almost creepy. Exactly what I saw when I returned from working in Japan to working in the United States. I realized the executives running the energy companies I worked for were completely snowed under by the technical jargon of the incompetent status-seeking "managers" as I constantly had to work around their lack of ability so that I could do my job. Unlike the Japanese managers, the Americans read some articles and talked the talk, but that was it.

This is not the case. Probably more relevant is that there are dedicated AI / Cloud Computing meetups and groups in the Bellevue and Seattle area that employees of all the companies attend. This means that the people that do this research and build these products frequently chat with each other.

I know my counterparts at AWS as a result and as we are friends, I push for collaboration whenever opportunities arise. At least on the MS side of the house these sorts of outreach and collaborative projects are a ground up push.

>Well, no. It's easy if they're unfit for team work (can't take criticism, can't take peer review) or not used to code reviews / pull requests.
In either case they are probably detrimental for the team.

I don't agree with this. Nobody has experience with code reviews until they actually do them. If we say that people without code review experience are detrimental to a team, how can developers gain code review experience?

Publishers are not entitled to breaking the law and distribute malware. Going criminal because their business model is having problems is a poor way for sympathy, and a straight way for open hostility between consumer and producer.

History has a tendency to repeat itself. Advertisement in email is today almost dead, where everyone has filters and blocks to prevent the flood of illicit actors. Telling people to "open your wallet/purse" is not the solution to spam, malware, scams, and fraudulent advertisement. Nothing short of a major rework of international law has any chance of putting that genie back in the bottle and turning back time. Its unlikely, so we all have to resort to blocks and filters to do the jobs for which normally governments and police do.
Thanks man. I'm going to try and incorporate some of this for my 12 year old daughter. If there's a simpler explanation of this for kids, that would help.

A couple of points of context.

The rally was organized by the "German American Bund," an organization that Nazi Germany had distanced itself from before the Madison Square Garden rally:

On March 1, 1938 the Nazi government decreed that no Reichsdeutsche [German nationals] could be a member of the Bund, and that no Nazi emblems were to be used by the organization. This was done both to appease the U.S. and to distance Germany from the Bund, which was increasingly a cause of embarrassment with its rhetoric and actions.

https://en.wikipedia.org/wiki/German_American_Bund

This was not a mass movement by any stretch, but seemed instead to be centered around a group of German-American immigrants.

The video depicts a Pledge of Allegiance ceremony that lacks the phrase "under God" because it was added in 1942:

Registering my kids for programs run by the City of Toronto (swim classes etc) used to be a nightmare. Registration was at 7am and the site didn't have a queuing mechanism so my wife and I would sit there with two laptops and two tablets hitting F5 repeatedly until we got in. It often took up to an hour to get in, only to find that the programs we wanted were already sold out.

I wrote a script using Selenium WebDriver that would open on multiple windows and keep re-trying until it got in. It would then process the configured list of programs we wanted to register for, find them, add the kid(s) and proceed to the checkout. Manual intervention was required to complete the purchase.

Except being morally objectionable and a PR disaster? No serious website would do that. I've completely stopped visiting The Pirate Bay after they put a miner there without users' consent.

The serious use case for these miners is that you have some kind of incentive for your users to mine, not just have it mine randomly in the background. I guess it works for pure donations but take a look at "Use Cases" on the front page for a couple of examples of what I mean.
How about you also copy the sentence that lies just between those two?

"As land slowly settles to a new position over time, the damper neutral position can be adjusted accordingly."

And if that doesn't work, the tube can have some kind of rails or just to roll over wheels on top of the pylons. (my own thoughts as non expert)

Rocket engineers with advanced simulation tools[0] have been working on this for 5 months before releasing the paper. Do you really think they somehow missed this obvious issue?

[0] https://www.youtube.com/watch?v=vYA0f6R5KAI

Edit: Further in the paper it says: "The tube will be supported by pillars which constrain the tube in the vertical direction but allow longitudinal slip for thermal expansion as well as dampened lateral slip to reduce the risk posed by earthquakes."

So pretty much what I've said. The other quoted sentence refers to placement of pylons themselves.

> why shouldn't it win every district?

Because we are supposed to have a representative government. If there's 55% Blue voters and 45% Red Voters, you're supposed to ideally have 55% Blue representatives and 45% Red representatives.

The example is a counterexample of this concept. Instead of 55% Blue / 45% Red split, the map as a whole becomes 100% blue. This is almost the very definition of "Tyranny of the Majority".

Ok, we did get rovers to Mars decades ago so I'm sure you know what I mean here, but you seem to be making my point that it's not worth it.

Simple isn't the same as easy, but an evacuated train tunnel with air or magnetic tracks does not require new science. The physics are well understood and simple. The hard part is evolving the tech to be reliable and cheap so that people will use it and pay for it - but that doesn't seem to be within economic reach, and that's before factoring in construction and upkeep.
“Hard fork” has a precise technical definition.
Why does it need a utility? When one spontaneously begins dancing, they aren't thinking of some practical purpose or end goal, they're just doing it because it's fun and they're enjoying themselves in the moment.

Anyone who has felt the flow of music come through them and freely improvised, either as a musician or a dancer, is in what I would deem a meditative state. In that moment, they aren't thinking about anything other than what they are doing right then and there, and they're having a wonderful time doing so.
