I'm wondering if this is why I find 120hz so jarring. It's almost as if I can't perceive the 'hopping' consciously, but I can subconsciously. It feels like my brain is asking "Wait, how did you get over there?" where "over there" is a fraction of a millimeter. I think maybe there is an uncanny valley for motion.
It's a Roku problem, not an HBO problem.
I’m not asking why, because anyone can find instances of mania in history such as this. Beanie babies. Tulips.

The law of large numbers, in this case—the speculative experiment of seeking returns from assets that do not produce value, will iron this out. History does not repeat, but it rhymes often enough for those who know the tune to sing along.
> I've never met any proponent of technical analysis who maintains that they can divine patterns purely from the shape of the candles, without knowing what they're trading or what day it is?

I have. The theory is that the fundamentals of the security are reflected in it's price movements, so reading its price action is roughly analogous to reading news relevant to the instrument. Also it's not really about looking at the "shapes of candles." That's a frankly primitive approach to technical analysis, and one of the biggest reasons that people keep drawing comparisons to astrology, numerology, divination, etc..
They call them sorts not kinds :-)

"Sort" comes from many-sorted logic where the sort distinction is at the syntactic level, so easily inferred. They are not called "types" because they don't come from type theory; there is no logical richness to the relationships between different sorts, unlike the relationships between types. They are not called "kinds" because that is the name of a higher-order concept in type theory.

This is certainly a good approach if you need that extra performance or plan on heavy use and that outweighs the extra ops. In my own experiments with Chrome and Puppeteer on Lambda, it has been rather slow as you also noticed.

With that said, if someone does want to use Lambda, it's easier than outlined in the article. Use one of the layers listed at https://github.com/shelfio/chrome-aws-lambda-layer and then `require('chrome-aws-lambda')` works fine, making it easy to throw something together even in the AWS console's own editor.

Withdrawal from alcohol can cause fits and even death. It's severe. That's why, during covid lockdowns, stores selling alcohol were often allowed to remain open.

Acquisitive crime has nothing to do with how dangerous withdrawal is. It's mostly about how expensive the drug is and how much is needed. Alcohol is dirt cheap.
> But tech companies want to talk to the humans they're hiring, so race and gender are (almost) always available as information inputs during the hiring process.

This is actually kind of funny to me, because in the open source world plenty of people have extremely productive working relationships without ever seeing or hearing each other, and in many cases without even knowing what country the other person lives in, how old they are, or what their legal name is.

So while there are definitely arguments that face to face communication is "higher bandwidth" or has other advantages, it doesn't seem out of the question to me that the hiring process could be "blinded" to a similar extent to orchestra auditions, without any significant reduction in hiring accuracy.

(Ok, maybe not quite the same extent; language fluency and style of speech are still significant signals even if everything is done over text)

Film rental has actually gone down a lot since the studios forced all the chains to go digital from 35mm film.

It wasn't uncommon for 80-90 per cent of ticket sales to go to the studios in the first week of a blockbuster's release, which would drop down to about 50 per cent in the fourth week or so. It was around 35 per cent for second run.

The average rental since the switch to digital has been about 50 per cent, although it's been a few years now since I was last running projectors in a real cinema.

> it's not like other ARM chip manufacturers are going to have to go through all of the same R&D expense to figure out how to make chips that are comparably fast--they just need to copy what Apple did without infringing on any particular patents

Very handwaivy but the devil is in the details of that "all they have to do". Copying success is not that straight forward or else AMD would have had a response to Conroe in 2007, Intel for Zen in 2018, and Qualcomm for A-chips around 2014.
It's well known that returns are both not normally distributed (obviously) and not even log-normally distributed (slightly less obvious, but still readily apparent). Moreover, it's pretty obvious that while markets don't conform to any form of EMH, they often trend towards efficiency over time.

This is easy to see in the massive consolidation in the market making space in traditional finance over the last decade and also you can watch it in real-time right now in the crypto space. Even two years ago, it was pretty trivial to be successful as a market maker using quite naive models and a system glued together in Python in a couple days. Today, things have gotten significantly more competitive: many single man operations have become uncompetitive and even larger (3-10 man) and more sophisticated firms are feeling the heat from behemoths like Susquehanna, Jane St, and Jump Trading.

It's amazing how you can feel the crypto market getting more efficient in front or your eyes. It's like running on a treadmill, and you're always terrified it will start going faster than you and your team can run.
These are web APIs, not Android/iOS specific, and IIRC Google and possibly other browser vendors have expressed interest in these APIs.

Web standards require voluntary cooperation and isn't something that can be resolved by allowing "better" standards variants to win in a marketplace over others (otherwise they wouldn't really be standards).

Apple has pre-emptively blocked the standardization of these APIs because they effectively have veto power, and they have veto power because web standards aren't really a free market. Browser vendors choose not to ship standards that major browsers don't all agree on, which means that Apple's singular objection scuttles the process by design.

Of course this is one of the risks you have with standards, one bad actor can screw everything up. It's why standards often suck and it's a happy miracle that the web is as good as it is. When Apple themselves can screw up a standard that they directly compete with (web vs native iOS) from the inside, well, that's just too convenient for them.

The idea that companies only need to do maximize shareholder value isn't that old and was only popularized in the 80s. If you restrict creating value to that, then maybe she didn't create any at Google. But maybe Google wants to create a software that works equally well for everyone and raising the issue of IA biases would have helped achieve that goal.

No, for technical analysis to work, EMH needs to be false.

If EMH is strongly true, then the price of a security will always be priced to the intrinsic value of the underlying. For TA to work, the price needs to be divorced from the intrinsic value because the change in intrinsic value of an asset doesn't follow any pattern.

If EMH is strongly true, even fundamental analysis should yield no alpha since all public information would be integrated into the price. That's why there's a distinction between strong and weak EMH.

Even if you know which accesses have a high probability of missing in core or chip cache, it is tricky to write portable software that takes advantage of (switches/branches to other work) the time it takes between prefetch and data available in L1.

From what I heard from people who saw it in theaters, the sound mixing was terrible so you could only understand half the dialogue, and it was overall very confusing. It was basically made for multiple viewings.
Movie theaters aren't going away. Once people feel comfortable densely sharing an indoor space again they'll spool back up offering that experience. You only need to taste it again.

The market will likely be much smaller given people have invested more into their home viewing experience, consequently theaters will need to stand out more.

Based on what I'm reading, and what I've experienced, I would say a lot of Bay Area companies "[create] a hiring system in which it [denies] qualified U.S. workers a fair opportunity to learn about and apply for jobs that [the company] instead sought to channel to temporary visa holders [the company] wanted to sponsor for green cards".

In some cases, these companies don't want to sponsor the employee for a green-card, but simply are satisfied with the work being done by the visa-holder, and want to continue to pay for that work. The companies don't want to have to look for qualified local talent every-time the visa renewal comes up.

It's only being mentioned alongside threadripper because the article went overboard and claimed the M1 "embarrass all other PCs — ... including ... every single machine running Windows or Linux"

This is a joke. The M1s performance is no where near the threadripper. Even on per-thread performance, new AMD cpus perform better than the M1... and they have many more cores. The M1 can only win these comparisons when we start adding all kinds of conditions, like power draw, heat, price point, etc. They need to add those conditions to redirect the conversation, because on raw performance threadripper destroys the M1.

The article made the mistake of leaving out those conditions to make it seem even more impressive than it is... but hyperbole and fantasy will always sound better than reality. Reality requires those conditions. That doesn't detract from the m1's impressiveness.. but it's foolish to forget that and go off and start making ridiculous claims like the article has done.
The gist is that C++ coroutines’ context switches are cheaper than cache misses. Hence, if you can write coroutines that fill the caches more intelligently than that the hardware prefetcher can do (because you know more about what your application is trying to achieve), you can outperform the hardware prefetcher. You write a whole lot of coroutines that fill caches, suspend them while they do it, and once they are resumed, you can assume that the caches are now filled with your data and have just achieved better efficiency.

Hope this was a clear enough explanation, and someone correct me if I’m wrong.

> The complaint also alleges that Facebook sought to channel jobs to temporary visa holders at the expense of U.S. workers by failing to advertise those vacancies on its careers website, requiring applicants to apply by physical mail only, and refusing to consider any U.S. workers who applied for those positions. In contrast, Facebook’s usual hiring process relies on recruitment methods designed to encourage applications by advertising positions on its careers website, accepting electronic applications, and not pre-selecting candidates to be hired based on a candidate’s immigration status, according to the lawsuit.

Important to note: the allegations, if true, probably only indirectly impacted you or me. In other words, we all failed our Facebook interviews the good ol fashion way - through incompetence - not unfairness.
Pervasive end-to-end hiding of memory cache misses using coroutines is a standard architectural feature of some database engines. It follows naturally from I/O latency hiding; systems designed like the paper suggests are well over a decade old in industry. However, the devil is in the details of the scheduler design when it comes to making the performance benefits robust in real systems.

The scheduler design is non-trivial because it is an inference engine that feeds back into the thing it is making inferences about, and there are temporal locality optimizations well-worth doing aside from hiding cache misses. A naive scheduler, like round-robin, can inadvertently cause the thing it prefetched to be evicted under real workloads. There are many examples of how a cache miss hiding design can suddenly turn into a cache miss creating design when the workload patterns shift modestly. At the same time, the scheduling logic, which is theoretically hard, needs to be simple enough that the cost is worth it. And you also need to manage tail latencies in real designs; robust and highly optimal schedulers in terms of aggregate throughput have a tendency to have high worst-case scheduling latencies. The tradeoff space is very complex and interacts with real design constraints in subtle ways.

Even if you address all of that in the scheduler design, the efficacy of these optimizations are sensitive to the physical architecture of the CPU cache, which varies widely. The scheduling algorithms are implicitly making assumptions about the design and specification of the target silicon.

tl;dr: This is a mature database technique with real benefits but robust real-world implementations are expensive to design. The code is simple, the cost is in being forced to think through the implications and edge cases so that your execution schedule doesn't get stuck in a pathological equilibrium.

I prefer miniseries. Netflix had the extended version of "The Hateful Eight" broken into a four episode miniseries.

The miniseries was much easier to watch, and didn't require compromises for running length.
