Can't turbo as much is still a net loss of performance. Even on Platinum turbo frequency is almost 10% lower with AVX512 on single core, and 30% lower with all cores. So you really want the majority of your software to use AVX512 to gain net benefit. It takes the system 2ms to recover after an AVX512 instruction.
But you are correct that the Silvers are way worse. I suspect Intel intentionally killed AVX512 performance on the Silvers. I tested power consumption, and there is no reason to reduce the frequency, except for the sake of it.
The sad thing is there is no CPUID flag to distinguish good AVX512 from useless AVX512. Would really be better if they disabled it completely on Silver. The way it is now will just hurt adoption.
That's why I say "you have conflicts" and have them resolve the conflict before I do the review. GitHub, at least, correctly diffs against master after the conflicts are resolved so you don't see any of the merged code (if it's the same as on the master branch), only the actual changes.

Doesn't that solve the problem?
That's a redefinition of what a blockchain is IMO.

That's definitely the definition some companies are operating under.. but really?

WALs and journals have existed for ages and both fit the definition of a directed list of blocks.

Hell, ext2 and FAT fit that definition (inodes forming a directed list of block-references).

I guess we all store our data on something that's technically a blockchain by your definition.

Great point.

In my personal experience, I haven't found any correlation between giddiness about an idea and it being right or effective. (Especially with startup ideas). So I watch out for excitement about an idea, write out why it would fail, wait for a couple of days and revisit it. If I'm still excited, I pursue it.

Correct me if I’m wrong but it sounds like what they’re actually testing is data transmission via HF antennas attached to power lines. The lines themselves are not transmitting data. Wireless ISPs certainly already exist. That technology isn’t necessarily new. Although I’m not sure what the significance of using the ‘millimeter wave spectrum’ is. Maybe someone has more insight?
It is confusing for me how bankruptcies work.

What happens if a corporate declares bankruptcy? Do they only pay less while keeping everything they invested/bought using the loan money, for example - buildings, equipment, stores etc? How does this compare to student loans?

People need to take a crash course into the community before making accusations like this. Simply looking at the protocols of the largest blockchain shows that no one wants crazy, overbearing government regulation; we don't even know who created it. Also, it's very naive when they associate blockchain with data and monetary values when it could be used to track anything. If I had an iPad in the bathroom, when I use the toilet I can validate it by pressing a button and reward myself with a Number 2 Coin. If I wanted the blockchain to be more secure and trustworthy I could open the window and text the neighbors so they could validate that I am also in the bathroom.
Without exhaustiveness checks for all your case analyses, what exactly is the point?
Yep, I'm required to make my work freely available when I can. Some of it is sensitive so not all of it can be, but otherwise we have to. Also all of my code and data is open source, which is not required but we have permission. Where I worked previously was totally different, it took months to get any code release approved.
Funny idea :)
It's not a redefinition, it's a definition that has been around since the 1990's [0], the only requirement for a blockchain is A) directed linked list (block points to previous block) and B) cryptographic security (use hashes as block index)

Bitcoin is merely the first application to use Blockchain in a decentralized proof-of-work manner.
This can, sometimes, work in you favour though since it is possible to get a county court judgement against these organisations for trivial reasons because the original claim isn't responded to.
I think its definitly not irrelevant though. The fact is, my bias is weaker for boys, at least I have to assume, since I need to think harder to come up with it. If this is true at large, it could be that boys are held to lesser expectations of conformance to a strict set of behaviors and interests.

I also find it interesting how once I do come up with the stereotypes, they do seem to lead right into the current job ratios.

Now, I don't know the cause of the stereotypes, they could be observations of nature, or creations of nurture, but I do find they tell a bit of a story.

Not eye-opening I'll admit, but an interesting detail.

> Why does it matter if Google is a telecommunications service or not?

Because we're discussing regulations that only apply to telecommunication providers?

I have never said antitrust laws shouldn't be enforced. In fact, I believe net neutrality is important even if we had a bustling isp sector.

Net neutrality is also not an issue because of local monopolies, although they make the issue more visible.

So, until you convince me that Telecommunication regulations should apply to companies that aren't providing telecommunication, I don't understand your point. Specially that data cannot be modified or throttled based upon content or destination.

I'll continue to agree with you that antitrust laws. I'm not sure what your argument is.

Assuming the bankruptcy isn't called off:

The bankruptcy is handled by a liquidator or trustee in bankruptcy. That person / entity will attempt to liquidate the assets and will then pay a portion or all of the debts in order of preference. If there is a remainder (unlikely, but it could be) it will be returned to the shareholders. Depending on the country some creditors will receive automatic preference (such as the taxman). In some cases, for instance if it is believed the company is viable but has been managed badly it is possible that such a trustee will even attempt to keep the company running while they search for a buyer.

If debts are re-negotiated or forgiven it is possible for a company to emerge relatively unscathed from bankruptcy proceedings, this all depends on what deals can be made with the creditors.

It compares poorly to student loans because those are individual debts and unfortunately individual debts are far harder to discharge than corporate debts.

Are you sure that it is intentional?
You can make the student loans dischargeable in the event of a bankruptcy, but at that point their risk profile is no different than unsecured personal loans. Which for a person with low or non-existing credit history (i.e. any 18-year-old) would likely result in:

* requirement for high down payment - perhaps 50 to 75% of the tuition being covered by student or his parents (through home equity loans or retirement account loans)

* frequent and aggressive repayment schedule, starting perhaps 30 days after originating the loan

* high interest rate, perhaps front-loaded into repayment schedule due to higher than normal default rates

* aggressive monitoring of the events related to debt performance, where missed class, late homework, substandard grade or a behavioral citation could result in interest rate boost

* incentives and price control mechanisms enforced by the lender - your computer science class will have a low interest rate, but that music appreciation class or gender studies gotta be out-of-pocket

I think overall that would lower the enrollment rate and force the unbundling of academic offerings. Not necessarily a bad thing, but I can see some people being against it.

A big problem with liberal arts currently is it is burgeoning with new fields of study that are truly political movements masquerading as scholarship -- where liberal arts should only be motivated by the search for truth.

It is a law of bureaucracy that it always grows absent some constraining force. A few reasons come to mind:

1. Have a problem or a new political goal? Make a committee, open a new office, etc. This is how bureaucracies see the world.

2. Unproductive employees? You can't fire them because of HR policies and unionization, and more importantly, because there's no constraining force creating a culture of efficiency. So just hire more employees.

3. No one who rises to lead an organization then campaigns to diminish it in size. Everyone thinks they are important and that their work is important. Having more people working under you makes you more important. Having fewer makes you less important.

These are problems in for-profit organizations, but the market provides a constraining force. An inefficient company won't be able to compete with a more efficient one and will eventually go out of business. Also, shareholders will demand that expenses are cut so profits, and dividends or share price, goes up.

> Mental illness does not sound like a normal state.

No, it doesn't sound like a normal state, but that doesn't mean it isn't a normal state for some people.

> I don't think he was talking to you personally.

I'm not sure who they were talking to. Myself, others in positions like mine, HNers, society at large, or the ether. Regardless, believing that the mentally ill can't be, or aren't in some fashion currently, responsible for themselves is ridiculous. They absolutely are in the eyes of both our society and the state.

> I agree in terms of individuals, we should not be expected to hold the burden themselves of others.

I agree.

> The same doesn't apply to society and the governance of it however.

I'd love to hear politically viable solutions that can cross-cut through the myriad issues faced by this specific community of people (the subset of homeless who are diagnosed and known to be mentally ill). I don't think SORs are going even get in the ballpark for them. If I tried to tell a delusional, manic, paranoid person that they need to go live in a room that the state says they are to now live in they'd balk and disappear within minutes. But, I really don't have anything to offer, either, and I think about it more than I probably ought to.

It is a blockchain is you don't merge since you have a commit pointing at a previous commit, (block points to block), merges point to two parents but Ethereum has that almost with uncle blocks.

The commit log of a repo is almost certainly a blockchain, which is why I mentioned "to some extend"
You recommended “Debt” on here a while back and so I read it and just finished it this week. Amazing read! So interesting how the language of debt is tied up in our conceptualization of morality. I see this everywhere now, mostly recently in this aptly named startup trying to build debt instruments on the blockchain: https://dharma.io. After reading their whitepaper I think the irony of the name is lost on the authors.

Anyway, thanks for the recommendation!
I can't speak for the original poster but both Chinese and Russian tactics have in the past largely depended heavily on ground based guidance. This is partly the reason for or perhaps because of their planes having inferior radar or none at all in some cases. This was the case during the Cold War. Things might have change since then. Perhaps this is where we get the notion that Chinese pilots are trained to strictly follow orders from the ground.

You are simply wrong.

Think of a blockchain as only one strand (say, the leftmost strand, from a leaf all the way to the root) of a Merkle tree. Think of a git repository as the whole tree. So no, they are not equivalent.

If they were there would never be a way to have more than one branch depend on a previous one.

US is pretty dismal at graduation rates overall - Department of Education is not even tracking the percent of graduates completing a 4-year degree in 4 years anymore, instead preferring a generous 6-year completion metric for a 4-year degree, which stands at 59% https://nces.ed.gov/fastfacts/display.asp?id=40

41% of all US undergraduate students have nothing material to show 6 years down the road except for the mounts of student debt. The quoted figure of 22% of those debts being in some kind of default starts looking optimistic.

People who "understand blockchains" don't agree on what exactly distinguishes something as blockchain technology, and people (and companies) are claiming all kinds of things as using "blockchain technology".
The article glosses over why the 4 hours was possible.

Firstly, a major challenge in training an AI of this sort is getting enough labelled data. They played 300,000 games from memory. Under normal circumstances, that requires access to 300,000 games played by experts so the AI can learn to copy what the export does. That is how Alpha Go did it.

AlphaZero neatly side steps this by generating it's own training data by playing itself. If how to do this was "obvious", it would have been done a long time ago.

Secondly, they parallelised things. Alpha Go trained the AI from the results of each game as it is played. AlphaZero played 1,250 games simultaneously, and feed the results into the AI as they became available. The result is it took well over an order of magnitude less elapsed time to train AlphaZero than Alpha Go, even though the CPU cycles may have been roughly similar.

Finally, he overstates how hard it is to customise the engine (Markov algorithm + AI) to a game. There are two pointers to this. Firstly, it took them over 2 years to create Alpha Go. It became the world champion on 23 May. Now, 7 months later we have AlphaZero. But AlphaZero didn't to play just one game in those 7 months: is the best player on the planet for 3 games: Go, Chess, and Shogi.

I don't know whether they customised the AI for each game, but I suspect if the input and output layers were wide enough to accommodate the largest game they could use the same one for each. The Markov engine does have to know how to make all legal moves from any game position, but coding that isn't rocket science or particularly time consuming. The AI does _not_ start out knowing those rules - it learns them from the Markov engine. It's all very DRY.

This sort of engine only works are a particular style of game - one where their is only a smallish set of well known moves at each step, and the playing board is also smallish (19x19 in the case of Go, with three possible states for each position: empty, black, white). Most board and card games fit this description. AlphaZero can teach itself to play any of them to a standard higher than any human can play them, and do it within a few hours, not the decades it takes to create a human grand master. The net result is Homo sapiens reign of supremacy at playing this style of game is now over. For this entire niche our brains have been firmly relegated to a 2nd class intelligence.

I don't know whether you would call pulling this off a breakthrough, but I do know the techniques they applied will be copied by man+dog for years if not decades to come.

Ex-wife was an english prof at a state university. They had students who came in with a 16 on their ACT, which really means they should still be in high school. They'd take remedial classes for a couple years, then most eventually filed academic bankruptcy.

Finance officer was telling me how for in-state students, the student is only paying around 20% of the actual tab, and that the state picks up the rest. Then there was the story from a few days ago where some poor lady ended up owing over $100k for a < $10k debt due to fees and penalty rates.

Even my own degree, in the "allegedly" hard subject computer engineering, first day of class would fill an auditorium. After midterms, class size would drop to just a handful of people.

So taxpayers on the hook for subsidies, former students paying obscene finance charges on a kind of debt that is almost unshakable, and little of that culminating in valuable skills and credentials...

Excluding the more selective institutions, higher ed is a racket, and the financing of it is an even bigger one.

Here[0] is a great article about what a blockchain is and isn't good for for. The tldr is that blockchains make tradeoffs that are bad for most things.

In fact, on almost every dimension, decentralized services are worse than their centralized counterparts:

They are slower

They are more expensive

They are less scalable

They have worse user experiences

They have volatile and uncertain governance

And no, this isn’t just because they are new. This won’t fundamentally change with bigger blocks, lightning networks, sharding, forks, self-amending ledgers, or any other technical solutions.

That’s because there are structural trade-offs that result directly from the primary design goal of these services, beneath which all other goals must be subordinated in order for them to be relevant: decentralization.
