I've studied cello from age 5 to conservatory degree; the pitches of the open strings are burned in my memory. I can also often tell which key an orchestra plays by timbral cues. However, I do not have "real" perfect pitch, although the topic study might find that I do. True perfect pitch is like the anecdotes in the thread: discomfort with "wrong" transpositions or tunings, learning melodies by real rather than relative pitch, internal references that can go out of tune with age. All these are completely alien to me.
all i know is i have to pay an ENORMOUS amount of money to pay for freight from US to Australia

So is this going to make it worse? Because this is an enormous incentive NOT to buy any US goods

Just curious: Why is the comment racist?
There are four components that effect range. Transmit power, attenuation, receive sensitivity, and interference.

Transmit power is easy, more power more range.

Attenuation depends on frequency in a cluttered environment. Everything being equal lower frequencies work a lot better than high ones. Contrary to what you'll hear or read radio signals in a cluttered environment doesn't follow an inverse square law in practice. It's a lot worse than that.

attenuation = const * distance ^ -k

Where k depends on frequency. For FM/AM radio (important where the tower is on a hill) k = 2.5

900MHZ k is ~3 and for 2.4GHz is ~3.5

So 900MHZ is a lot better than 2.4GHZ. 433 is likely better than either.

Receive sensitivity depends on the antenna and front end design. And modulation type and strongly on the signal bandwidth. And very importantly the presence of interfering signals. Low data rate spread spectrum will give you the highest receive sensitivity.
I guess this is a good opportunity...

It irks me a bit that scoreboarding is not considered "out of order execution" in modern classification. If I have a long latency memory read followed by an independent short latency instruction, the short second instruction will execute before the first has finished executing in a processor with dynamic scheduling via scoreboarding, but this doesn't "count" as OoO. I mostly get it, it just bothers me.
No, because those costs are paid regardless of how many packages you receive from China.

So sure, people living in the US are paying those costs "as a whole", but you don't pay any additional cost when you order a package.

It's like how driving on public roads is free, in the common sense of the word, even though of course the costs are still "paid" somehow, by somebody.
Great analysis. I wonder how a semi-log graph would look.
This has been going on for quite a long time. WTO constantly ask China to explain and China keep coming up with explanation / excuses, depending on how you view it.

So something needs to be done, either China truly opens up its market, or continue this trade war disputes for decades to come. ( Which might turn into a real war )
Amazon is a very big fan of this change. They've been arguing in favor of this for years. The postage welfare program enabled Alibaba et al. to inexpensively lob attacks into Amazon's primary shopping market, from China, where Amazon can't go to compete. It's a big win for Amazon and most domestic US manufacturers and retailers.
Initially, I only intended to find images roughly showing Europe (I don't travel that regularly), but hey, that'd be even cooler! Might even create a little script so everyone can get a dynamic background of their personal earth position!
Polling every ~85 minutes would be fine though, since the 16 images are cycled across the day every 1.5 hours.
Having a ZX Spectrum would in no way actually help you learn hardware. The only thing it would do is to reinforce its realness, so to speak, which would help to motivate you to learn it. But it would not actually help you learn it – the design and learning curve of assembly language is what it is, and having access to running hardware (compared to having an emulator) does not change that.
Both Apple and Google make money hand over fist, quite profitable.

I used to use a US parcel forwarding service to shop online and have things forwarded to me in Canada. One of the services they offered was first shipping the US origin package to their warehouse in China (presumably via some kind of discounted or chartered freight service) then forwarding it on from there to the destination country via China Post. This could actually be cheaper than mailing something directly from the US to, say, Switzerland due to the low UPU rates out of China.

Love how people are claiming they are going to close down Windows for gaming back in the GFWL days and it never happened.

Now we have the Microsoft Store, whille substantially better, Windows hasn't even attempted to close down the system and yet again everyone is claiming they will. They aren't, and they won't, the Microsoft Store still hasn't urserped Azure or regular Windows keys in sales or profit. So why would any company close off their system potentially losing more sales on Windows keys, it just makes no sense.

Can we please stop touting this bullshit?
I would have imagined the uniformity in finger lengths between identical twins would be the limiting factor.
A smart guy once told me that the easiest sales pitch is "I've got money for you!".

Think how you convince the buyer that your product will help him earn more money/ save more money. If you can e.g. get a percentage of the money that (s)he makes/saves, that's very often an easy sell.
If you want to help poor people, subsidizing imports from China is a stupid way of going about it.
But the issue here is not the differential in efficiencies.

It's China receiving subsidies from the US because it was considered a developing country in 1969. It's not anymore, it's a global superpower now, it can pay its own postage.

Because it will make some goods much more expensive for everyone in the US. This can have unintended consequences.

Its great for voice conversation and chat. Much better than Skype.

The store is overkill. It will further bloat the client, and had none of the features that customers want (which is basically all the features of Steam) or devs want (which is basically DRM, global reach and localisation, patch management, and a lower cut than 30%).

The way the store is setup now is basically only suitable for games at the end of their lifecycle. There is no way to patch the games, as far as I can see.

The -one- good thing I will acknowledge is its curation. It was remarkable logging into the store and seeing a good-looking list of great games. Its become a bit of a tire logging into Steam and seeing loads of Hentai, porn, and Chinese games (Steam doesn't support title localisation) not to mention all the junk uploaded as part of Steam Direct $100 fee.
if China loses its status as a developing country, all that's likely to happen is the items will end up being shipped from a neighbouring country that still has the status.

When you buy items from AliExpress often they have the option of being sent by Singapore Post. I'm not exactly sure how that works (Singapore isn't that close to China), but although the item comes from China, to the postal service it doesn't.
First off, the "single engineer" was Levandowski, the person who basically started Google's self-driving team and was the lead for the project, not any random person. Second, this was back in 2011, and that was in the early days, "Waymo" wasn't a thing until 2016. This is just a bunch of engineers experimenting, not a real product. Lastly, the person who did this is long gone.
> Also remember that sometimes it's not a good fit, and that's okay

One can go beyond and suggest alternatives to their own product that might be a better fit. Remember to keep customer's best interest at heart.

I'm in dev tooling market and have suggested open source tools as alternative to my own products numerous times. The kind of trust I gained through it is immense.
Yes it is correct. They have no business asking this. If a question is incorrect, you can answer whatever you like to it.

Lying is only giving wrong answers on correct questions. If a person sticks their nose where it does not belong, too bad.

This is interesting to me, not because of the musical implications but because of the neurobiological ones – and especially with regards of learning accents / pronunciation of second languages.

There has been a lot of studies that have tried to teach recognizing the audible difference of R and L to Japanese English learners. I don't know of a single study has been able to produce robust results. (There's a primary and secondary acoustic cues to the difference; some Japanese have had success recognizing the difference using secondary acoustic cues, but recognizing the primary cue which is the most robust one and which the natives use preferentially escapes treatment.)

However, the testing protocols and time are limited, and we have increasingly knowledge about adult neuroplasticity. Results like this keep me hopeful that it's just that we don't know the good way to do that yet and we might see some results in the future.
Most actions disproportionately affect the poor and middle class--that doesn't mean we shouldn't take them. Although it doesn't always work out in practice, ideally, other wealth redistribution policies should blunt the impact of said actions. That said, $300m is not very much, so it seems largely like a symbolic gesture.
Potential energy from gravity goes to kinetic energy of stable vortex ring rather than kinetic energy of falling down.
That's a very dismissive attitude. There are limitations with the study, but the methodology is sound.

At this point the only competition I could forsee is Epic launching their own storefront. They have a giant audience thanks to Fortnite, and could heavily integrate the store into the engine.
I understand your point, but who knows if these things aren't really the same? My opinion is that having the notes "burned" in your memory is a lesser degree of the same phenomenon. People that are considered to have "real" perfect pitch just developed these abilities beyond what normal musicians like you did. And doing this at a very young age really helps a lot, in the same way that leaning new languages in infancy is a painless activity and quite difficult at adult age.
And in some cases, suspicious behavior has included:

* reading math textbooks while Indian

* wearing a turban

* praying

* talking to spouses in a non-English language

and worse.

So I guess we just disagree on the definition of "suspicious behavior".
The author here, I apologize for any confusion from my writing. We do use WebRTC in a server-like fashion. The browser attempts to establish a P2P connection with the host computer, and the peer negotiation is similar to if you wanted Chrome to talk to Firefox for a video call. The network of either end could both cause connectivity to fail which is when we fall back to direct WebSockets rather than a costly TURN server.

IMO, sleep trumps everything. One month ago I sacrificed exercise in order to sleep more. Lack of good sleep had destroyed me. I felt drained 24/7, whenever I sat down I had trouble getting up.

I feel better now.
Digit ratio is actually a very well studied effect. Hundreds of studies have been done on it.

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

The wiki page references at least 10-15 studies discussing its correlation with sexual orientation.
IBM was doing essentially all that stuff before 1990 or so except possibly for multiple threads per processor core. So, there was pipelining, branch prediction, speculative execution, vector instructions, etc.

Then I was in an AI group at the Watson Lab, and two guys down the hall had some special hardware attached to the processors and were collecting and analyzing performance data based on those design features.
> Pianos evolved from older instruments where each string had fixed pitch

Interesting. But my point is actually unrelated to history.
It's related to the tradeoff between "easy to play" and "expressive power":

There are some steps you can take, as an instrumentist, in the "easy" direction, while still keeping enough expressive power.

> Removing challenges devalues the personal satisfaction of mastery.

Surely. It's unclear, though, how instrumentist mastery correlates with musicality:

Some virtuoso guitar solos can be considered "non-musical". To the other extreme, some great composers don't use any musical instrument (from classical music composers, to Amiga sequenced-music composers) - some of them can't even play their own compositions properly!

> Making any art simple makes it trivial and unexpressive.

This reminds me of an old a running joke on french TV, starring a fake David Guetta having a custom piano built, with only one key ( a reference to the intro of "I Gotta Feeling" ). I think it's safe to say that you can't express a lot with a such a piano :-)

However, a smart 10-key "piano" opens new horizons: because now it's reasonnably possible to "play" multiple pianos at the same time.
I can certainly see new forms of mastery and non-trivial expressiveness here (e.g a setup of 4 "smart keyboards", each of them using a different sound).

It may still cost less. At least shipping a big thick book form Germany to the US was cheaper than shipping the same book within the US.
Amazon fought state sales tax until the writing was on the wall, then Amazon caved and we got overnight shipping instead.

I wouldn't be surprised if something similar happens. In Europe hobbyking, banggood et al opened European warehouses once VAT enforcement became a problem.

The big chinese retailers will start competing with Amazon, which is somewhat ironic since Amazon already acts as the US warehouse for many Chinese products. Good riddance to dropshippers though.
SideWalk Holes – An Image Segmentation Dataset
If you have very well developed perfect pitch, you can sense the difference just in the same way that you can feel that two strings are out of tune by a few Hz. That's why some people with perfect pitch like Mozart get annoyed by out of tune instruments.
Well, I can't get any enjoyment when I'm sleepy. Try to watch a movie, I fall asleep; try to read a book, I fall asleep. So if you lack sleep you can't get enjoyment anyway.
Having implemented security protocols and used state machines to track state, this is a surprisingly easy (if embarrassing) mistake to make. It’s very easy to spend a lot of energy validating the documented state transitions and essentially forget to ban all other transitions.

For me this is much less “OMG how could they be so careless” and much more “There but for the grace of a diligent set of testers go I”

True, but that’s frankly still a net positive side effect if you add climate change to your model.
So basically US is moving in the right direction regardless of the Paris agreement?
I'd say a good thing to add will be that the lion share of progress in last 5 years was done around cache architectures.

All what is described in the article like superscalarity and ooe has been squeezed to the practical maximum at around early core 2 duo era, with all later advances mostly coming without qualitative architectural improvements.

In that regard, Apple's recent chips got quite far. They got to near desktop level performance without super complex predictors, on chip ops reordering, or gigantic pipelines.

Yes, their latest chip has quite a sizeable pipeline, and total on chip cache comparable to low end server CPUs, but their distinction is that they managed to improve cache usage efficiency immensely. A big cache would't do much to performance if you have to flush it frequently. In fact, the average cache flush frequency is what determines where diminishing returns start in regards to cache size.
This is no doubt obvious to hardware folks, but one enlightening moment is when I came to understand register renaming.

Previously I had the (wrong) idea that rdi, rsi, etc corresponded to physical bits. Register renaming involved some exotic notion where these registers might be saved and restored.

Now I understand that rdi, rsi, etc. are nothing but compressed node identifiers in an interference graph. Ideally we'd have infinite registers: each instruction would read from previous registers and output to a new register. And so we would never reuse any register, and there'd be no data hazards.

Alas we have finite bits in our ISA, so we must re-use registers. Register renaming is the technique of reconstructing an approximate infinite-register interference graph from its compressed form, and then re-mapping that onto a finite (but larger) set of physical registers.

Mostly "register renaming" is a bad name. "Dynamic physical register allocation" is better.

This may be really cynical, but... I bet we'll get news like "our tests were based on our employees and we're surprised the system fails for black people / asians / ..." fairly soon after first implementation. So many large companies fail on this, I don't have high expectations for TSA.
It's difficult to respect black and white statements like this. I get that it's always better to accomplish social goals peacefully, but plenty of social progress has been made by dictators that eliminate opponents.

Take Turkey, for instance. Mustafa Kemal ruled forcibly in many ways, and almost certainly had dissidents killed. He fought in the Turkish war of Independence so he has blood on his hands one way or another. But I'd seriously question the judgement of any who would claim that his rule was bad for Turkey. He drastically improved the country's institutions and brought is social policies more in line with Western ideals. In the coming years the military would repeatedly overthrow legally legitimate governments to keep the country secular. There's an honest discussion to be had over whether or not Turkey would be in a better person if Erdogan had been overthrown.

Of course in a liberal Western democracy, which I assume you live in, doesn't stand to benefit from regimes like that. But the blanket statement along the lines of "dictators bad, democracies good" is not productive, and sometimes feel like willful ignorance of history. This killing is a poor forecast, but time will tell whether history remembers MBS as Saudi Arabia as an Ataturk or a ineffective, bloody ruler (or, much more likely, as just another average Saudi monarch).

How old are you? You sound young (under 35). Once you reach 35 and probably earlier, you will change your mind.

When you're young your body can take almost everything. I know that when I was 20-22 I would sleep maximum 6 hours per day because I felt the way you describe.

Now if I don't take at least 7.5 hours per night (with as few interruptions as possible), my life goes to hell, I feel drained, tired and lost, with depression looming.
