Charcoal Grill vs. Gas Grill Throwdown: Let's Settle This Once and for All
Other than stars etc., I don’t think know any genuinely omnidirectional light sources. Even other substellar objects emit non-isotropically because they aren’t spherically symmetric. And at most frequencies, light doesn’t diffuse much.

To put it another way: lasers, lenses, parabolic dishes.

Does anyone have back-of-the-napkin estimates of total passenger throughput for central public transportation vs ride share transportation for any metropolitan area?

If public transit i.e. Muni serves 10x or 100x riders each day vs ride sharing than I see your point... I think.

Wait. Maybe you could spell it out?
You say that like political will is merely a matter of wanting it bad enough. I don't think that's true.

As a college student, I wrote an alternate commuter rail plan for Solano County around 15 years ago. It was based on GIS and research and lacked the politicking that strongly influenced the existing rail plan.

I was told gas would need to be $4/gallon before the stations would be built. I was sick and going through a divorce and had been a homemaker for 2 decades. I have no political connections and no political know how.

Some months ago, I tried briefly to figure out how to promote that plan. It basically went nowhere.

The first rail station had its grand opening in April. I believe this increases the odds that Travis AFB will finally leave California like the federal government has threatened for years.

The worst of the three stations has yet to be built. I updated the website yesterday and stuck a link in my HN profile.

That's probably as far as it will go. I'm no longer in California. I'm still struggling to solve my own problems.

The rail plan research I did is dead in the water.

I wish I had the know how. I wish I had the right connections. I wish people took me more seriously than they do. I wish I had to be time and energy to pour into figuring this out.

I don't. I have to get on with my life and none of that fits into my schedule. I've tried. It went nowhere.

No one thinks that you just hook up ML to a camera and you're done. Literally everyone working on this only uses ML for identification. When that Model X crashed into a highway divider, it was because the lines on the road were very faint and there was a fork in the line that actually wasn't the _real_ lane line. The car followed that by mistake, but only because of the misidentification of the lane line.

How are more sensors going to tell the difference between a plastic bag and a cat? How does lidar tell you which car is parked on the side of the road and which one is in your path? Relying on a dozen sensors seems like the crutch to me. Nothing about our current world has been designed for lidar and radar. It was designed for binocular vision. Sure, if your only goal is to not hit things at low speed in perfect weather, lidar is great. But you can't get much further than that.

I was trying to imply that its probably the best avenue for research, and also we may never figure it out, might be a dead end.

However I would say the reason it is used so much in sci-fi is it currently the one way we can cause action at a distance faster than light, which is so tantalizingly close to communication.

Gravitational waves could be a prime candidate. Assuming that you have enough power to create one it could travel to the other side of the universe without any kind of interference. Whether you can embed a message in them is a whole different story though, we couldn't possibly know with our current understanding.

I'm writing a programming language from scratch called Basecode. It's very early days yet. The bootstrap compiler (written in C++) is about three months away from being complete. Then I'll rewrite the compiler in Basecode itself to make it self-hosted. After the language is self-hosted, there's a second level of features I'll be adding that I think are quite exciting.

He means with a car. I would be very averse to buying a house somewhere that required me to drive everywhere.
I suppose the reason is related to the cliche "companies just do whatever they can to maximize shareholder value"; it is instead that they don't actually act to maximize shareholder value, they act to maximize future expected shareholder value. I'd imagine that the guys leading the Google push into China are well aware of how things will go, and they've likely even reported it to the top brass. But shareholders probably aren't as well-informed, so they'll happily bid up the price on GOOG on the back of stories about an imminent takeover of the Chinese search market... which has roughly the same financial impact of actually achieving something, at least temporarily.

Mind you that the french aristocracy was dealing with a revolution which upheaveled the entire meaning of being a royal/noble, it's principles and the "entity" that they derived their "rights" from.

Prior to the french revolution, many royalty's (including the french) got their righteousness to rule from 'god'.

The french revolution was the first which actually abolished this ancient idea and tried to hold the nobles accountable to the state. (early revolutionaries even wanted to keep the bourbonnes, until the jacobins and Robespierre came around and ended that rather... certainly).

Intel CPUs (since Westmere, 2010 [1][2]) encrypt with AES GCM (the recommended cipher suite for TLS) at gigabytes per second per core [3]. You can saturate 10Gbps pipe on a single core.

My laptop can do 1,400 RSA 2048 sign operations per second per core [4], 16,000 P-256 ops and 25,000 X25519 ops per second per core [5], so I wouldn't care about handshake performance either.

With large files, you don't care about the performance of the handshake, but if you do care about handshakes you can reuse http connections and use TLS session resumption for new connections, which avoids the relatively expensive asymmetric crypto (with modern servers, ECDHE and RSA digital signature). libcurl will do it, among others, so build your client using a good https library.

I might br mistranslating concepts.

The idea is that you have a university, like NYU, which is comprised of colleges, like comp sci, economics etc. You go to your specific college, like major in something, and they count you as their student. You also apply to colleges specifically but are then also a student of the university.

There are also independent colleges. Some of them are good enough that they eventually get accepted into a university. Some aren’t. Sometimes the university itself founds a new college like a new major and builds it up. Like when I studied CompSci it had been some 10 years since it became its own college, but was still physically hosted by the college of electronics and the college of mathematics. It first became a course within those some time in the 80s. Nowadays it has its own buildings and stuff.

At the same time there was a multimedia college founded around the time I went to uni. Features video and stuff but also a lot of web development. They were not allowed to join the university and take tuition (I think government only funds universities). Uou can get a college degree in webdev, but not a university degree in webdev. So it’s more like a post high school vocational education.

I believe in broad strokes we have the german education system if that helps.

No problem at all! I was being a bit tongue in cheek with my response, too. I wasn't really offended or anything.
A mature civilization could probably perform a kinetic bombardment with masses accelerated to a significant value of c. There would be waiting, but there would be no need to travel here personally.

That said, I'm not particularly worried about it either. I suspect we will either have scientific value (independently evolve intelligence, which appears rare) or never pose a real threat to them, assuming learning curves remain exponential for civilizations.

Not as good as Germany or DC.

Did you just claim DC public transit is good? Wow. Coherent bus lines are few and far between. Light rail is non-existent. And the Metro is falling apart at the seems... Prone to excessive delays. Entire lines are brought down for extended periods to perform decades of deferred maintenance. There's no ring routes - to get from Dulles to Rockville, you have to go all the way downtown and back out again. The system was built without consideration for express lines. And neither of the DC airports are on the same line as Union Station.
Is there a specific case you're referring to here?

Yea maybe 6 years ago, but today this is no longer true. Speaking as someone who rents a free-standing house in LA, and has looked at what renting in New York would cost. LA is no longer cheaper, as a good portion of New Yorkers have migrated in pursuit of this exact ideal.
I would second the 4-Hour Workweek, yet I am still searching for a profitable idea. How long did it take you from reading the book to reaching the ability to quit your job?
municipal rail is a money sink. currently across the nation there is over a hundred billion dollars of deferred maintenance on municipal rail; light and heavy. worse bus service tends to suffer because they try to force people to use rail by making bus service less attractive which in effect is just damages the concept of public transport.

no the real solution is get over this mythological idea that America is too car heavy. everywhere that people get freedom of travel they go their own transport. what automation will bring is freedom to those who cannot drive so we best better figure out how to get cars talk to each other and which areas will be reserved for automated driving only.

funny you mention Seattle, a city that blew over their recent rail budget by half a billion dollars [1]. plus is it also a city deferring maintenance to hide the costs of their folly.

> Do you have any examples? I watch almost all of their public hearings and it's rarely ever grandstanding.

That's true of most committees; the difference that makes SSCI seem better is that non-grandstanding hearings (or moments of hearings) from, say, the Senate Committee on Agriculture, Nutrition, and Forestry have roughly a 0% chance of ever getting coverage from the major media, whereas, due to subject matter, SSCI hearings can be newsworthy without grandstanding (though the grandstanding still gets far disproportionate coverage.)

> Part of it is also to function as a communication channel to the people. It shows their constituents that they're asking the questions people want them to ask and it would give Google's leaders a chance to explain their company-wide position on issues in this case.

If Google needed the opportunity of an SSCI hearing to get any message it (or a client) wanted to virtually any audience of concern, the uncontroversial portion of the premise for inviting them to the hearing would collapse. Page showing up improves the ability of the Senators that have prejudged Google to get media coverage of their grandstanding, but it does nothing for Google's ability to have it's message reach any audience it cares to have it reach.
There's no value to Google in voluntarily cooperating in a hearing concerning matters on which so many members of the committee had publicly, explicitly, and in quite immoderate terms prejudged Google and where the terms sent clearly were incompatible with an intent of productive information gathering rather than political scapegoating.

It's, of course, the prerogative of Congress members to use hearings for grandstanding with high value PR target witnesses as props as a means of gesturing to their constituents about their concern on an issue. It's also a very good idea for those high value PR targets to decline to voluntarily cooperate when it is clear that are being invited as punching bags. (It's both good for the punching bags and good for the integrity of the process of government.)
Just as a point of reference here - I'm not taking sides in this debate, I vividly remember reading about the 1999 Toronto 87 car pile up.

Fog on a straight road caused an 87 car pile up after a trailer jackknifed. The point in the article I remember at the time was a mother recounting watching her 14-year old daughter burn to death. Mom got out, but the daughter had been pinned by her leg.

The quote from the time was ""Mama Sheila, please don't let me die. I'm only 14," Marceya McLamore begged."

I suppose my point is that neither human or machine are good enough yet. and not to treat this as an abstract academic topic, it's real people.

Arguably, but it's hard to demonstrate the negative. At best, we can compare Tesla accident rates to those of other vehicles in the same class (luxury sedans). I'm sure you're right, but proving you're right against the naysayers is a different problem.
The Great Leap Forward is known by almost every Chinese, many of whom having family members actually experienced that. That said, having millions of people starved to death has been quite common throughout the history of China. They could be caused by war, by natural disaster, by human, or a combination of multiple factors. Even in 20th century, starving has been commonplace until the economy started to improve after the economic reform in 1978 (a huge accomplishment that is often ignored by western people) It's hard for younger generations of Chinese to even imagine the darker ages.
It's amazing the serious face some people keep "re-discovering" 100+ years old, derived from basic principles technology. The ultimate of this is the autonomous truck convoy: wouldn't it be amazing if we could just have trucks follow each other closely and save a ton on air drag?

Well, yeah, it exists, it's called a train, it's magnitudes longer than any "autonomous truck convoy" ever will be, and instead of the billion dollar AI machine learning big data system we have to keep them close together, we use a fricking mechanical linkage.

I'll cross my fingers your speculation is correct.

There will now be an "apparent absence of good alternatives" in the iPhone camp too. The SE will be nearly EOL hardware soon, and the smallest iPhone is now a 5.8 inch screen. The minimum price point is also now $750 for current hardware. The SE was partially a low cost option for emerging markets as I understood it, so either they're planning on previous year hardware as the affordable option, or they'll need to release something that doesn't cost so much soon.
I think the idea is not whether we could speculate in a useful way about an FTL or otherwise seemingly impossible phenomenon that we are not yet aware of. It's more about the probability that phenomena and technologies that are far beyond our current understanding can exist or not. In all likelihood we would have the intelligence and technology of ants relative to a million year old civilization. We shouldn't limit what is possible in this universe to what ants are able to comprehend and achieve. Even without such an argument, we only need to look at what we thought was possible 500 or 1000 years ago, and extrapolate forward that in all likelihood our currently understood limitations of physics will all but be irrelevant in 1000 years.

Agreed that it's a flight of fancy to speculate on these yet unknown capabilities, but that doesn't mean they aren't highly likely to exist.
