So you can use magnetic field information about a star to learn more about the planets (tidal forces) orbiting it?
Interesting. Thanks for the tip, I'll give that a shot. Hardware differences are negligible, in fact the machine where FF is noticeably slower is the faster machine. Especially start-up is super slow, takes a couple of minutes at times.

There is some psychology amongst the regulators that results in them not fining or sanctioning large players because they don't want to make them go bankrupt and further consolidate the market.

You can have a monopoly in America, as long as you don't do anticompetitive things to get there, and don't do anticompetitive things while you are there from within your company. (protip: the trick is to change the laws and regulations to favor advantages you have and make it impossible for new entrants)

Yes, but it was a a mostly US ICO. If it happens in the US it's subject to US regs.

Funny enough, none of it is legal in Canada apparently and Canadian citizens were not allowed to participate in the ICO.

Why not? It's bonus money for MC, why wouldn't they be happy to sell Google access to your transaction data? They don't have to do anything but copy the data and hold their hands out for millions and millions of dollars. Why in the world wouldn't they make that deal? Privacy concerns? I have my doubts.
Why should penalties necessarily bankrupt the company? Shouldn't the penalty be proportional to the damage they created by doing things improperly?

The fact that people don't actually want to do that? People are free to live their lives the way they want. There's no reason to pile most people into cities just "because cars"

Amazon may be unwilling or unable to be multi-cloud. Companies worried about being stuck in a silo may think twice if they have a more convenient option.

Besides, crdb does worldwide SQL databases now, and the only competitor at that level is not Aurora, it is Google Cloud Spanner, at a much higher price range and with very limited options.

It comes down to what you mean by "should".

Curiously, the meaning has changed radically over recent centuries, and such change will probably continue, along with change in the meaning of the title question, howsoever expressed.

> Is 3 atomics on the same cache line a legit problem?

This is a commonly known problem called false sharing. https://en.wikipedia.org/wiki/False_sharing

To be fair: I don't know how these particular atomics work, maybe they're all on their own cache lines, and 192 bytes are used up for those three atomics so that things are done properly (unlikely, but possible). But atomics in my experience usually assume the "external" programmer figures out the buffering issue to prevent false sharing.

2. These are atomics declared to be SeqCst memory ordering. That means the L1 (and probably L2) caches are flushed every time you read or write to them on ARM systems. (x86 has stricter guarantees and almost "natively" implements SeqCst, so you won't have as many flushes on x86). The cache must be flushed on EVERY operation declared SeqCst. Its absurdly slow, the absolute slowest memory model you can have.

3. Well-written spinlocks are absurdly fast. Benchmark them if you don't believe me. The assembly in x86 is

Lock:
while (AtomicExchange(spinlock, true) != false) hyperthread_yield(); // loop until you grab false.
acquire_barrier(); // Prevent reordering of memory

Unlock:
release_barrier(); // Prevent reordering of memory. NOP on x86 but important in ARM / POWER9
spinlock=false; // Don't even need an atomic here actually

Literally one assembly instruction to unlock, 3-assembly instructions to lock (the atomicexchange + loop) + hyperthread_yield if you wanna play nice with your siblings (reduces performance for you, but overall makes the whole system faster).

From a cache-perspective, the spinlock will play nice with L1 cache (if a thread unlocks, then locks again before a new thread comes in, it all stays local to L1 and no cross-thread communication occurs).

So pretty much every aspect of the hypothetical spinlock implementation is faster in my mind. I don't really need to benchmark to see which one is faster.

EDIT: At bare minimum: because the Spinlock will be properly written using Acquire / Release half-barriers, they will be ABSOLUTELY faster than SeqCst Atomics. You'll need to use Acquire/Release Atomics if you want to "keep up" with the Acquire/Release based Spinlocks.
So which parts of the government should we give more power? The CIA? The FBI? Any part of the justice system? Those government agencies have plenty of power and funding especially with the “War on Terror” and the “War on Crime/Drugs”. Private corporations don’t have the power to take away my life/liberty/property. The government does. Given a choice between corporate power and government power, I would rather see less government power.

Even the military is a wasteful mess because of government power. The military has told the civilian government that they don’t need some of the weapons or military bases that they are getting but the government - because of corporate meddling -keeps funding things that the military has said they don’t want.

Why would you trust these same government officials not to be persuaded by corporate officials. This is the same government that got rid of Net neutrality, bans cities from creating municipal broadband, extended copyrighted repeatedly and protects draconian DRM.
No university affiliation is required by arXiv or any other journal I know of. You should put some affiliation, but it can be your own thing like _Full Metal Jason Labs_.

However, it's hard to write well for an audience in a given field without having gone to grad school in that field. Readers will sense that your paper is from an outsider. So stick to topics that people will believe an outsider about. Proofs and working systems are good, criticisms of common methodologies are bad.

When you publish, especially on arXiv, you still have to get people to read it. Zero people wake up in the morning thinking "I'll just browse for new papers from people I've never heard of." You might email a few authors of recent papers you're citing saying, "Hey, I really liked your paper on ___. I've just published something related on arXiv that addresses a problem you mention in your future work section..."

Ya know, I know everyone hates the big guys, but I’m pretty impressed with the new releases, including the Apple Sign On. I personally have never liked the way Facebook Connect or Google have implemented their frameworks. To add random email and optionality (not sure if others allow optionality with sign on or if they are still all or nothing based on requested permissions) is a win in my eyes. Yes, the requirement is a little strict but that’s why their ecosystem yields consistent experiences across apps. And yes, they aren’t a non-profit, but most of us have signed up for capitalism and if this enhances our privacy long-term then I don’t think this is the worst outcome.
I wish them well but fear this won't work out for them. This sounds like a smart move until you realize that they are just one of many players in a crowded market and that this actually decreases their value proposition for end users and external contributors. Having less of both is bad news for an OSS project, no matter how you spin it.

The way I see it this type of company has a short term value that derives from them being first (more or less) to market with whatever it is they do well. In this case, their thing is having a sharded/clustered db that can replicate across datacenters and with serialized transactions.

Awesome, that's a great thing to have and it will take other databases a while to get there. But they will eventually and that matters. This stuff commoditizes quite rapidly. It's based on published research by Google half a decade ago and people can look at the source code and algorithms. It's just a matter of time before somebody else figures out how to replicate what they do in some other product. Somebody like e.g. the postgresql developers: https://tapoueh.org/blog/2018/07/postgresql-concurrency-isol... and https://pgdash.io/blog/postgres-11-sharding.html. It's probably not perfect yet but they are obviously heading the same direction and there's a notion of good enough and diminishing returns.

When it does catch up, it all reverts to which is the best product in the market. Part of that is features but another part of that is a robust developer community and having access to robust support and hosting options from multiple companies. A failing VC backed company that controls the code base and treats it like a walled garden means that community is only as good as that single company behind it, i.e. not very good. It simultaneously repels potential users and contributors thus slowing down adoption and development speed while increasing the R&D burden for the single backing company to not fall behind any further. They can't win that game.

In a nutshell, postgresql does not have that problem and it never will. Mysql doesn't have that problem either. Both developer ecosystems consist of collaborating frenemies that work together because it is better than not doing so. Both provide pretty good database solutions with plenty of hosted solutions (including Amazon and other cloud providers), commercial support via several companies, etc. Also both are pretty much guaranteed to continue to have active development for as long as there are people willing to sell their time doing that and there are so many companies using both that there is just no way that that would change within the next few decades or most likely this century. Essentially all of the current companies behind both could go bankrupt and all that would do is create an opportunity for new companies to step in and take over.
> 2. Lockfree can be faster -- This is the case most people hope for.

it's not about being faster, it's about never returning control to the OS if you want to achieve soft-real time in one of your threads (a common application being audio processing where you have to consistently fit as much as you can do every 1.33 milliseconds for the more demanding users).
If there's contention between multiple CPU cores (and worse, sockets), 3 atomic ops on same cache line puts the max throughput to 3-15M operations per second per system. Probably around 10M on most 2-4 core CPUs. Multi CPU-socket systems will be slower.

That is, the point when the whole computer is on its knees due to cache coherency traffic between cores.

Note: these are just ballpark figures based on real life experience on modernish x86-64 systems. Your mileage may vary. Always measure actual performance. Etc.

Here in Canada, the "hysteria" is due to the perceptible economic slowdown, bordering on recession, associated with the carbon tax.
If such a minor tweak is enough to make businesses pull investment, then surely more than tripling the price would be ill-advised.

Then you have the fact that transport, and hence fuel, affects the price of most goods, so fears of a recession (decrease in purchasing power) are not unfounded.

Also consider that, while justified as addressing a "tragedy of the commons scenario", rarely do such tax dollars go towards mitigating the externalities in question.
The tax would sting less if it was being spent building renewable energy rather, than initiatives that are charitably described as contentious and perhaps more accurately described as pandering.
If we could avoid the graft and self-dealing usually associated with federal spending, that would likely cut down on the complaints as well.
well said.

Heres where I think it is anti-competitive. Lets say you are building a streaming service. You choose to be android only, because you want the majority of the market, and calculate that you dont need the Apple users. Your competitor complies with more apple rules, and goes cross platform. They win because they chose to be cross platform.

It's hard to win (and by and large you usually need to be a winner, to exist in the long run) without offering your product to people, whichever device they choose to access it from.

Apple, despite being a non majority of the market share, is a king maker, they can choose the winners. And if they want to, they can cripple their competitors through a combination of app store rules, payment processing requirements and limited api access (streaming, payment, maps, etc)
i would be interested in seeing that, because I do consulting for suppliers selling to Amazon and rarely see flucuations like that on badges.

If I were an evil decision maker at Amazon, I would have the algorithm pick products that are well rated with low return rate, but have high inventory that doesn't clear fast enough.

I don't see where the USDA opinion supports the author's argument that the USDA now says "hemp" can contain any amount of THC. The opinion states that the THC in hemp is no longer a scheduled drug but the definition of hemp in the farm bill limits the amount of THC in the plant or derivative to no greater than 0.3% by dry weight. If the plant or derivative contains a higher percentage it is no longer hemp but marijuana and no longer subject to the "THC in hemp" non-scheduling.
I'm not necessarily exhausting the physical capacity of a single datacenter to expand to another datacenter, I may expand early or from day one to run queries closer to the user even if the workload is a few seconds behind. I don't think Follow-the-workload works well for that scenario.
Zimbabwean here but live in Canada now. There are numerous older people back in Zimbabwe who probably haven't seen a toothbrush aside from an ad in a newspaper (they are 70+ years of age). No Alzheimer's to speak of its possible this is an anecdote but I don't hear of its prevalence there or other non-north--american countries. But then again those countries don't have as big of a media footprint and research. I still think it's something westerners do (or do not do!) that causes its prevalence here.
Because Google removes consumer choice and forces vendors to play ball with its search platform on Android devices. Microsoft does not make you use Excel on Windows, iOS or Android. Google can cripple your entire company or industry by cutting APIs. You can't do that in Windows, even if Microsoft bans you from volume licensing, you can still install Windows on virtually any machine.
This was inevitable. As I said two years ago[1], just listen to Kik's own words:

"When we looked at raising another round [of VC funding], we asked ourselves how do we answer the question about how we will become a profitable business [...] We didn’t have an answer we really believed."

... so instead they decided to raise money from unsophisticated investors in an unregulated market, where nobody asks such inconvenient questions! No surprise that the SEC is upset.

Spinlocks don't return to the OS.

Mutexes are spinlocks for roughly 1000ish cycles on both Linux and Windows. If you're in-and-out before the 1000 cycles are up, the typical mutex (be it a pthread_mutex or Windows CriticalSection) will never hit kernel code.

If you take more than 1000ish cycles, then yeah OS takes over as a heuristic. But most spinlock code won't take more than 50 cycles.

>> Tell me how I'm supposed to safely take a left

> You pull up and stop in front of the cars to your right on the perpendicular road. You turn your bike 90 degrees. You wait until they get a green light, and you ride straight ahead.

So now, if you have a red light in the direction of the road you're going in and it changes to green, you now just have to cross the intersection and wait for the full duration of another red light before you can effectively make a left (all while watching left turning traffic from the road you were originally on proceed with a protected left turn phase.

> I've seen a light for the bike lanes and a light for the right turn lane. When the bike lane is green, the right turn lane is red.

I've also seen videos[1] where drivers don't comply with the red light prohibiting right turns. The problem is that drivers will see that through traffic has a green light and will assume that it's okay to make a right turn because that's how most intersections work. Introducing a brand new configuration leads to issues where motorists will make mistakes to the detriment of cyclists.

> Not the case, you just need to learn what the bike lane asks of you

This seems to be inconsistent from intersection to intersection. As a driver, it's just easier to follow the rules of the road for drivers of vehicles when I need to make a turn at an intersection.

these type of arguments are really immature and dishonest. So what if a billionaire or a world leader is flying around in Jet. How is that an argument for us to destroy our habitat for future generations. statistically speaking how much of global warming is cause by private jets vs the rest of it? if the 'influencers' are not gonna talk about it then who else is? and will it matter?

if you take a step back & see you'll notice these type of arguments are designed to evoke an emotional response in a casual observer so they dont feel the need/desire to further engage in the (admittedly) marginally interesting topic.
