At some point we need to decide which we value more: attractiveness to CEOs or the happiness and healthiness of hundreds of millions of regular, everyday people. I think it's reasonable to give up any pretensions at capturing the former if it ultimately benefits the latter.

Latency-sensitive applications over 4G/LTE, like SSH or games feel sort of sluggish.
Ray tracing hardware being included kind of worries me actually. Unless they're selling it at a loss I can't see it being below 500 dollars with the prices of ray tracing capable cards being as high as they are.

As far as PSVR, the herculean amount of effort required to get something in the vein of backwards compatibility going between PS3 and PS4 makes me think it was designed from the ground up to work with basically everything PS4.

Is there any evidence to attribute that process to the effects of oligopoly?
In general, no. In a lot of the established USA, all lines were run overhead on poles. New neighborhoods are typically now built with underground everything, but that's here nor there. The densely populated parts of Louisville where Google was attempting are all overhead phone/power/cable. Going underground would have been prohibitively expensive.

I’ll admit: I wasn’t a person who was wowed by the picture of a black hole. For all intents and purposes, it isn’t a very good picture.

Reading this write up gave me a much better appreciation for the difficulty of actually just capturing that image, which is, I'm sure, what people wanted me to focus on when seeing the photo, but that sort of context requires a write up like this, and can’t be relayed through a blurry small picture.
Fair enough. I was active in BBSs but didn’t remember walkthroughs. But then I knew a number of the authors and just asked them if I was really stuck :-)

It's beautiful. A marvel of engineering. Such a major, iconic part of Paris. It's survived so many wars. The Nazis could have destroyed it, as they destroyed the Winter Palace outside Leningrad. And as the Allies destroyed so many cathedrals in Germany.

But it survived. And to be burned out by some idiot with an agenda would be so sad and pointless. Indeed, whatever cause the idiot was supporting.

But of course, it'd also be sad if it was totally an "accident". An electrical fire. Someone who left a heater running. Or didn't fully extinguish a cigarette.

Anyway, I'd be very suspicious if someone claimed responsibility. If for no other reason, because if it had been a terrorist attack, we would know by now. A key point in terrorist attacks is having them be obvious. Not looking like accidents.
You probably don't want the drives combined for that, though. You want the active game to be fully loaded onto the SSD.

So at that point of needing a pretty big SSD, make the console less expensive by only having the SSD, then let the user plug in a cheap external hard drive. Five minutes to transfer a game is pretty reasonable.
Can someone help me understand this better? What is "very close" to 23.8-GHz frequencies? I don't know which bands 5G operates on, but it seems [1] that the closest they get, at least in the US, is ~27 GHz. If the FCC is auctioning 3000 licenses for the 24 GHz space, is that the space that can potentially interfere more? Can 5G operate on just any frequencies, then?

Not sure that Exclusive Titles is an artificial reason. Some of the best games I've experienced have been released/published by Sony and their first party studios.

The quality, story, characters, and graphically fidelity are often unrivaled by their contemporaries. God Of War(2018), Horizon Zero Dawn, the Uncharted series, and Shadow of the Colossus (remake) are some of my favorite releases of this generation. I'll gladly plunk down $400+ for their next gen console for more games like that, I don't focus on the tech specs, but rather the experience their platform provides.
People who want to see ads are the exception. I'd argue that it would be better if Apple used id=0 as the default.

Some Thoughts on Military Revolutions – Andrew Marshall (1993)
My large regional cable provider recently tripled the cost of modem rental to $15/month so I bought my own.

Opened the next bill but instead of seeing a $15 drop it was the same. Thought it was an error but no, they just unilaterally raised prices on a bunch of other services.

What can I do? There's no other option for me.

I get there are Byzantine local and state regulations that make last-mile internet unprofitable or a low-margin, commodity business, which is presumably why Ruth Porat and other bean counters at Google killed this effort. But improving America's internet is a social good that Google could invest its massive profits into; instead leadership would prefer to build repression-enabling tools to compete in China.
12 is divisible by 3 and 4 which added equal 7 - the number of visible planets. 11 and 13 aren't divisible. Lunation cycle != lunar return. A lunation is a synodic period. There are 12.3 lunations per year so the nearest whole number is 12. The tropical year has 4 turning points - 2 solstices and 2 equinoxes. That the number of lunations in a year is divisible by the number of solstices/equinoxes is very significant and non-random.
7.1 for positional audio. Your ears are sensitive to the direction of sound in more than just left and right. They can also determine front from back, and up/down (for sounds in front of a person).

Headphones simply can't mirror that effect, and you can tell this by simply turning your head while wearing them. If the soundscape doesn't change, it's not going to be accurate in terms of position.
I think you misunderstood what I wrote.

Core.async lets you freely mix both. You use the same channels, the only difference being that your coroutine blocks will be wrapped in `go` and use `<!` (parks coroutine if it needs to block), while your full threads with be wrapped in `thread` and use `<!!` (blocks). It makes the tradeoffs explicit (the tradeoff always exists) and isn't a problem at all.

Cell capacity is a shared resource. The reason (or part of it) that Verizon limits your speed is to let others use it too. 5G brings smaller cells and more capacity in each cell, which means less need to throttle.
A Dialog with Your Data Using the New Dataclips
NIMBYism alone also isn't the problem per say, it's zoning plus NIMBYism that makes things hard. A vocal minority can effectively block zoning changes, which prevents developers from building high density housing. This is exacerbated by CA's so-so to terrible public transit. High density housing is far more annoying for whoever lives nearby when everyone living there has a car or two and the builder didn't also build a parking structure for those cars.

This is mostly a problem for coastal California too because land is limited and expensive. In inland California a developer can just buy and build someplace else.
Inter-process communication in Linux: Using pipes and message queues
EDIT2: In spite of my personal experience I do think the author makes a strong case for this: "Adding up task estimates is a really misleading picture of how long something will take." Perhaps I've had better results because I try to give myself a little padding in every task, just considering that everything requires not just typing code but getting on some calls, having back-and-forth in emails and the project management tool, testing (automated or manual), fixing a thing or two, etc. So my individual estimates are probably a bit higher than median. When I work with other developers they consistently estimate lower than me. But my numbers are deliberately not "best case", because then you know you'll go over on the total.

Or "the plane is certified such that the remaining engine has enough power to take you to the crash site". Indeed.

As outlined above, you double the probability that a mechanical problem occurs. (For p small, 1-(1-p)^2 is around 2p).

Now, if the pilots are very much on top of things (well trained and current), then they can control things and safely land at the nearest suitable airport. However, if they make a mistake (and that's surprisingly easy [1]), it could easily be fatal.

A single-engine plane with an engine failure, in contrast, becomes a bad glider, with a decent chance of surviving the ensuing forced landing.

> My iPhone 7+ isn't limited by 4G LTE, it's limited by Verizon deciding to only allow it 10mbps down (with great signal)

This is in fact a limitation of 4G.

A single device is fine, but there is only so much bandwidth available. When you get lots of devices in the same area, something has to be limited.
“Modern techniques” are specifically calibrated and engineered not to last on the timescale of Notre Dame due to the costs involved.

Modern construction techniques are of very little use to repair a building which was itself built over the course of 150 years.

“Modern” gets you the $200mm staircase to nowhere at Hudson Yards in NY.

The question is for a building which actually struggled to raise the $7m used for the initial repair project, are people going to be patient enough to spend the $700m and 10/15/20 years to rebuild it with anything approaching the care, quality, and craftsmanship of the original?

The reconstruction should be the life’s work of a great master (or several great masters, when you consider the art and ornamentation that goes along with the architecture).

Do we still even do that sort of thing anymore?
> "this is the history of the Cathedral"

Exactly! Time and physics doesn't care about history. Wood will rot, metal will corrode, stone will weather. Hell, the earth itself is undergoing continuous reshaping every single day. This rebuilding is just another chapter in the cathedrals history.

Besides, think of how prestigious it sounds to say you played a role in the reconstruction an 850 year old national landmark. I know what jobsite I'd like to work on if I were a master carpenter.

So how do you explain all the famous male scientists and inventors of history? The most famous of them all are because they discovered cool things, not necessarily the "hardest" or "most significant" thing. Everyone knows e=mc2, but most people do not know about von neuman architecture, even though the latter has had a significantly greater impact on peoples lives. Taking the first picture of a black hole is as sexy as it gets in science. Katie would be famous no matter what she was.
I totally agree with your point that the Notre Dame fire is unfortunate, but that we have to accept it as the Cathedral's history.

However, I think that from an architectural and art historical perspective, we can do more than just reconstruct the Cathedral exactly the way it was. Art and architecture always change with their cultural and historical context, and I think it's one of human kinds biggest strengths to create something new out of old or destroyed artwork.

A great example is the Cologne Cathedral Window, which the German contemporary painter Gerhard Richter designed in 2007, long after the window had been destroyed in World War II: https://www.newyorker.com/magazine/2008/05/12/many-colored-g...

I disagree. Estimations tend to be just as wrong even when the tools are well known.

There's always that one edge case you haven't considered, that one algorithm that doesn't work as well as you expected, that small change to the requirements the requires a completely different approach.
Luckily, Google only touched a laughably small area of the city, one which isn't really going to cause a huge headache with road construction.
> this is the history of the Cathedral >

Exactly. There aren't many old structures that don't have a history littered with damage or complete destruction and rebuilding. Natural disasters, invaders, accidents. I like to think that those events are becoming less frequent with increasingly better tech and a more civilized world. This one was an anomaly I think. It will be interesting to learn the cause(s) and see what practices might be put in place to avoid them in the future.
The Basilica of St. Paul's in Rome (https://en.wikipedia.org/wiki/Basilica_of_Saint_Paul_Outside...) has a very similar story. It's even older than Notre Dame (4th century) and was burned nearly to the ground in 1823 by, wait for it, an accident involving a worker repairing the roof. The church was rebuilt using contemporary methods and today it's regarded as a treasure.

I foresee a similar thing happening here. A 1000-year old roof is an architectural treasure, but it's also a 1000-year old roof, with all its attendant challenges. The church will (someday) be rebuilt in a grand old classical style, but with a soupçon of modernity added as well. I think will be in some sense better off as a result.
Zuck is a massive liar and a corrupt businessman. The guy had to pay millions and millions of dollars because he stole Facebook's original idea. And he tried to screw the co-founder out of the hundreds of millions of dollars.

I hope to avoid a political debate, but the left has plenty of negative messages too. The rich are too rich and don't have to pay taxes, the poor are too poor, racism never completely went away, the corporate world is unfair to women, and so on. I doubt there has ever been a political movement without any negative messages. I should add in support of your point about social media having a propensity to negativity, these negative left-leaning messages tend to spread faster than the positive ones, just like on the right wing.

There's a lot of speculation in this article. I don't know what documentation exists of Notre Dame's roof structure, and from the way these (foreign) experts are talking, they don't know either.

A point cloud scan is a particular kind of record, one which doesn't include information about construction techniques or materials. It's good for capturing geometry, to the point of excessive accuracy.

This situation is a bit like analysing a plate of food using a mass spectrometer. The data is incredible but it doesn't overlap at all with what went on in the kitchen or on the farms where the food was grown. It doesn't tell you how to recreate the meal.

Point clouds are nice to have, but they are really a souped-up form of photogrammetry, and not equivalent to a survey performed by an expert human.
Potential reason: while these companies have a virtually unlimited amount of cash, resources such as top-talent and management mindshare are limited.

That's interesting - I'm working on using cell signal strength as an indicator for live weather features! There's a simple relationship between signal strength and clearness of weather - light rain has a distortion signal, heavier rain a heavier distortion, etc.

I'm betting that when all is said and done, the cell phones will help the weather forecast more than hurt it - but this may take some years if the cell companies are too greedy about it.

I'm working on detecting weather using all kinds of phone sensors like barometers and cameras in All Clear if you're interested: https://play.google.com/store/apps/details?id=com.allclearwe...

>I've done both, and (for me) it's the opposite.

Headphones provide a worse spatial experience than stereo speakers where the source material has been mixed for speakers; the equation becomes significantly different with flexible spatial formats like Dolby Atmos.

>You can feel decent sized speakers with your whole body

Using headphones with a subwoofer is a workable (albeit highly antisocial) option. You can't feel frequencies above about 150Hz, which is comfortably within the bandwidth of most headphones. You can also fit a low-frequency transducer to your chair, which will provide a similar feel to a powerful subwoofer without annoying the neighbours.

https://soundshaker.com/

Speakers are undoubtedly more convenient and more practical for shared listening, but headphones provide a simply unmatched price-to-performance ratio; to get the best out of a pair of speakers, you need to spend at least as much on acoustic treatment to control the resonance of your listening environment.
Given the choice, I'd always pick the 7.1 system. I've been forced into playing primarily headphones because of where I live, but it pales in comparison with my old 7.1 setup. There's just something about the whole room being filled with sounds and vibration that you feel with your whole body that can't be replicated by headphones. If I ever get to live in a house again, first thing I buy is a good 5.1 or 7.1 system.

Yes, Google collects user data and uses it for ad targeting. That's a more fair telling of the situation. If this concerns you, you may opt-out of the process.
The trouble with trumped-up charges, is that often outsiders don’t have the capacity to determine that they’re bogus. I mean, the point of extradition is a trial, and the point of a trial is to determine guilt.

Of course, as you seem to he referring to Assange, just remember the UK is (it claims) leaving the EU, and is currently run by people who don’t really know what they want but are fairly sure that whatever it is involves getting on well with the USA.
As far as I know if the action is not a crime in the home country there is no extradition process.
Allergies, asthma and autoimmune disease rates are skyrocketing and it's not at all clear as to why.
that's moving the goalposts as to what constitutes took X years to "complete". you can use any of those things after a few years of construction. But they are boundless for expansion.
