I'm not sure if you've been paying attention to equity prices. EM crisis, yield curve flattening, currency volatility, upcoming rate hikes, near-record P/E ratios, NONE OF IT MATTERS. Investors are bidding the ES and the QQQ to infinity no matter what the economic reality on the ground is.
Definitely not a stupid question, just the wrong question IMO. The real question would be do we have any reason to believe that they do still use radio?

We've had radio for just a little over 200 years and we've already realized its limitations. The fact that we can even speculate about quantum communication leads me to believe that radio is definitely NOT the end-all-be-all. If you scale human civilization into a 1 year time frame we invent radio at 3PM on December 31st. It's successor likely emerges January 2nd at the latest. Radio communication is likely a blip.

Radio is efficient over short terrestrial distance but horrible for long (galaxy scale) distance communication. If interstellar travel is feasible at all it will have to be at FTL speeds and an FTL communication system would be necessary.

If FTL is truly impossible then it doesn't seem like there is much point in listening since everything is so incredibly far it's irrelevant even on a species-level or planetary-level time scale. I believe that everyone at SETI must believe FTL is possible because otherwise it truly is a waste of resources.

Key word is "ethnically and culturally homogeneous enough". And since we're talking about political policy here, domestic image is what matters here.

The actual numbers are not known because they aren't collected as part of the census, but the government estimates that upwards of 98% of the population is "ethnically" Japanese. Furthermore, many of the ethnic Koreans that you mention, as well as ethnic Chinese (the next biggest group, as I'm sure you already know), are culturally fairly assimilated, even if many are second class (non)citizens in the eyes of laws and much of society.

The guy who started iRobot, Rodney Brooks, doesn't believe we'll see a true driverless car operating throughout a city on normal roads until 2035 at the earliest: http://rodneybrooks.com/my-dated-predictions/

As software developers, we all know how big the difference between "a demo the boss is excited about" and "reliably working in production for all users" can be. Given how complex the domain is and how many edge cases it has, I can easily believe Brooks is right here.
I don't think anyone is arguing that K12 education in the US is perfect.

End to End Testing Flakiness - at my last company we spent a large amount of engineering time automating end-to-end tests. In the end we found them flaky, maintenance heavy and couldn’t get to 100% browser coverage. E2E tests are of huge value but their costs are still too high.

Hey all, so this is the project I've been working on for my phd - it's basically a multimedia sequencer, but with the ability to express conditions (of the kind "if... then" as well as "when... then"), loops, and hierarchy, in order to write interactive scores. A special visual syntax has been devised to be able to express these elements graphically. The doc gives more details : https://ossia.github.io/score/

It's still in alpha but has already been used by multiple artists : https://ossia.io/gallery and has a great interoperability story with many creative coding environments (Max/MSP, OpenFrameworks, Processing, etc) due to native OSC (Open Sound Control) support.

The code itself is C++14/17 and Qt. feel free to ask me anything about it :)
I am the same way, I advocate a lot for replacing legacy LBs (F5? Citrix? blech) and software not really suited for LB functions, a la Apache, with HAProxy. It's working out well so far.

Combine that with a nice network and a tasty [EI]GP and be in pure web-serving bliss (of which I've only worked on two networks with that kind of design forethought, which is a shame).

In light of all the comments about the "missing" TLS, I want to point out that it would be a bit weird if the install processes used by the FOSS software ecosystem were dependent on a form of centralized authority such as TLS. PGP as currently used is distributed, which is arguably a good thing.

What science? Most of it is focused on whether the drug has effect compared to placebo/other pills, what unintended effects it has, and not on trying to understand how brain works.

Pill may have effect, yet the hypothesis may still be nonsense. Chemical imbalance hypothesis is really old, and doesn't account for a lot of new information since last 50-60 years.

It's in principle the same problem as when psychotherapists/clinicians try to develop a theory of mind. The result is that we have several major contradictory theories of mind/schools of psychotherapy, and all of them work/are helpful. Yet the usefulness can not be used to validate the underlying theories of mind the methods are based on, because that would mean that all of those theories are valid.
There's a ton of great responses in this thread. Allow me to go a bit meta: this is a big topic, and as you enter it, you'll eventually find out which parts of it appeal to you. Do you care about parsers? Type theory? Garbage collection? Code generation/optimization? Notation as a tool for thought?

Ever since I started programming, the idea of writing my own language was a sort of "white whale". I have one idea for a language that I think could be usable in a very particular domain. For that, I wrote a very primitive tree-walking interpreter (terrible performance, very technically uninteresting). The idea for the language was what I wanted to explore. I recently started writing a regex->jvm bytecode compiler. That's much lower level, and if I stick with it, performance will be what I optimize for. In neither case did I do anything interesting with parsers, though I used to love learning about new parsing techniques.

In that vein, see dfox's suggestion to "just use hand built recursive descent parser and some set of ad-hoc lexical analysis subroutines". That's the fastest way to get started, whether or not it'll be the best in the long term.

So, my advice is to explore and figure out which things you're interested in, and what you want to accomplish. That will tell you where you want to invest your time.
>HTTPS does not provide meaningful privacy for obtaining packages. As an eavesdropper can usually see which hosts you are contacting, if you connect to your distribution's mirror network it would be fairly obvious that you are downloading updates.

This assumes that package hosts segregate themselves by all possible privacy-related dimensions.

They don't. If you host illegal-in-country-X content on AWS and someone downloads it there, HTTPS would've prevented that from being seen. HTTP does not.

---

HTTPS belongs everywhere. It has flaws, of course, but there's no reasonable alternative at the moment. You can't predict what governments will decide in the future, and HTTP-now means they can record it and apply rules retroactively if they change their mind. This kind of thing gets people killed.
What an odd comment to make :) It's true you can ignore all economic reality and focus on growth (fake or real). But history time and time again has shown that NOBODY escapes economic reality. Nothing goes up forever.

"Debt, we've learned, is the match that lights the fire of every crisis. Every crisis has its own set of villains - pick your favorite: bankers, regulators, central bankers, politicians, overzealous consumers, credit rating agencies - but all require one similar ingredient to create a true crisis: too much leverage."
Copying, especially in the Information Age is immensely powerful. Sure, the market selects between a successful copy and a shitty one, but there's still a long way to go before lack of a healthy [internal] market impedes China's "progress".
Nobody will accept liability for actions outside of their control, and car manufacturers can not possibly afford to insure all cars they sell in perpetuity.

Insurance only works if the insuree bears the risk (and it has to be an actual risk with nonzero probability times cost, i'll leave why as an exercise to the reader) and in the case of car accidents, that risk is liability, which people have and computers don't. Can TSLA or Uber be charged and convicted of vehicular manslaughter?

Lower rate of accidents will just lower the market rate of insurance contracts.
That's an interesting viewpoint. Though, I view it more as; if you're starving and I have 10 apples, should I give you an apple? Why shouldn't someone else?

Should the surgeon really do the work for free when 100k to him means a lot; but 100k to Bezos is meaningfully less?

By the same token, if there's someone in front of me who needs help and I can help them with 5 cents? 5 cents is nothing to me, I'd do it in a heartbeat. $10,000 I could also afford, but it would be a considerable risk for my life and long term happiness.

The point I'm getting at, is expectation of helping someone or doing something noble seems to be relative to how much excess you have. Though, another important angle is how likely it is to help someone. I don't give $25 to charitable TV advertisements because I don't trust them. Despite being able to afford $25 to help someone.

So it's definitely complex, but correct me if I'm wrong, but your barter abstraction doesn't feel right to me.
The Real Google Censorship Scandal
Using Rails Session Cookies for API Authentication
disclosure: I never went to college. I was a C student in highschool.

I started studying 15 years ago to be an engine mechanic. I apprenticed with an occupational outlet in my state that paired me up with an 'old-timer' named Simon.

I was paid a regular wage to simply show up, and pay close attention and learn. for the first year or two i had no major responsibilities outside of oil changes or other pretty rote things. Finally one day I had the responsibility to do a major overhaul on a large diesel generator on a job site. I showed up, and Simon handed me a sheet of customer specifications and rework specs. I didnt realize until lunchtime that I had been crawling all over that engine for 4 hours, doing all the work myself. Every individual thing I did was part of what I'd learned, and I did it without so much as a second thought. I did it to Union spec, and I was troubleshooting real problems.

When the time came, I signed off on the work that day and certified as a master mechanic that week.

I guess what im getting at, is that at no time was there a question about my education, or my pay. Why is college different? How is it different? Why are there so many shady players?
But that in itself is a signal, right?

Say you have two sets of two entangled particles, all four particles in similar states. You have one particle from each set, your partner has the corresponding particles in the sets.

You check both particles you have, and:

- if both particles have similar state, then your partner hasn't checked any of their particle states, because neither have collapsed.

- if one particle has collapsed and is in a different state than the other particle, then you know your partner has at least checked the state of one of particle sets, possibly both.

If you partner is 50 light years away and checks it only seconds prior to your check, then they are signalling you at faster-than-light travel, right?
An advanced civilization, when looking to signal other potential civilizations, would hopefully -

- use the lowest common denominator long range communication medium (like EM waves), not the most advanced technology available to them, and

- would broadcast it widely in spatial, temporal and spectral dimensions and not worry about efficiency
Medium has become a pay site, eh? Oh well. I won't bother them with reading any of their free articles either.

That's the paradox, isn't it? You want something that doesn't interact with matter until to reaches the detector, where you want it to interact as much as possible.
1) I'm thinking by this you mean where the battery is non-removeable and where there is no keyboard. This was definitely something new.

3) WAP ... heck that was irrelevant since phones started having color screens. Browsers in the older Blackberries and Windows Mobile phones of the time were not WAP, but pre-WebKit applications that only implemented a subset of HTML.

4) Microsoft wanted to treat phones like it treated PCs - it would collect on software licenses. Hence it didn't see the device as something it controlled beyond selling an OS license for it. This made sense before Internet was cheap and fast on mobile devices.

iPhone was definitely a start of a major new era. I think the most significant thing is that iPhone was able to more or less end up as the boss of its own platform in the manufactuer-carrier relationship. Before iPhone, the OS was seen as something that would have to be approved by the carrier and device manufacturer.

This must be coupled with a land VALUE tax, not as calculated by the value of the current content of the land but for it's speculated value relative to neighboring land.

I agree. I don't even think that this is a good response by the EU. I was mostly commenting on how you shouldn't be surprised that they had _a_ response when other powers are locking down their internet and foreign companies we're running rough shod over EU laws and directives.

I think its all stemming from the same response as a portion of people who voted for Trump, or why the GPDR was enacted. The status quo was being abused by the major players and now they are going to do _something_ to shake up the system. Whether their approach is the right thing to do is up for debate
Re: "not much to invest in." - In the factory era, investing in new or better factories or stores was the usual use of excess cash. But most new industries are labor intensive, not asset-intensive. You can invest in start-ups, but many argue there are already too many questionable startups floating around, not unlike 1999.
Look at us as an example though. We've had radio for a little over 200 years and already realize its limitations.

Smoke signals will have been around for a lot longer than radio. Smoke signals will have been around for 99.9% of the timeline and then 0.1% radio before quantum. To an outside observer it would look like radio was just skipped.

If you scale human civilization into a 1 year time frame we invent radio at 3PM on December 31st.
Non-violent Communication by Marshall Rosenberg. After reading this book, the way I related and communicated with people completely changed.

Concretely, right after I read it, a break up that would have been very tense for me became straightforward and peaceful. Also, using NVC techniques, a fight with my friend got transformed into both of us getting tearful and pulling over the car to hug each other because we felt so connected.
These are tough issues, but they're probably not all relevant in the suburban Phoenix area where Waymo is getting started. Maybe it rolls out one city at a time for many years and that's okay?
>until 2035 at the earliest

Could be correct. I think likely it is correct. BUT, everyone thought we still wouldn't be winning games of Go by now. So could be wrong.
Correct me if I'm wrong but my understanding is that newer theories of physics do not exactly overthrow older ones. The conservation of energy for example still holds true for everything that Newton observed it at but for in other situations it falls apart. So E=mc^2 is an extension of the original law. Same thing with the theories of relativity, they explain Newtons observations as a subsection of a bigger system.

Afaik nothing in current physics prevents FTL from being logically possible. Nothing predicts it either but that doesn't mean it's impossible.

> 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.

In what cases does it matter that stars are not symmetrical enough to emanate light omnidirectionally? Stars are pretty close to isotropic.

A self-driving car is a mobile monitoring station; every such behavior will be closely tracked, recorded and possibly shared with the authorities. I think those drivers will learn to stay away from them.
Great point.

I wonder if MA's and PhD's should now be minted by those simply trying to reinforce ore reexamine certain areas. Or maybe trying them in different contexts. Like what happens to the principles if we do the experiments with African villagers etc. as an example.
Considering the size of these, and their incredibly light weight design, that's probably a bit unlikely. With current technology, they are not capable of carrying much of a payload.

It's great research, and very cool design (both mechanically, as well as the driving software), but frankly, these types of flying mechanisms just don't scale well and don't have much use. (But please don't take that of a criticism of their research, I think what they've done is awesome and I really look forward to see what they do next.)
It'd be nice to see a follow-up post on how to keep this setup up-to-date with the latest security fixes without service disruption.
We like the idea of technology improving our quality of life because as a civilization it's worked for us spectacularly so far. Driverless cars are appealing because they build on top of a transportation solution that already works, reducing the problems and externalities of it, without requiring us to completely overhaul the way we build cities and live which could take decades. When half of the world lives in remote or insecure areas, driving vs public transport is not a lazy lifestlye choice like eating poorly. Autonomous cars will also bring about a lot of new use cases which could improve public transport design, reach and usage, like driving you to a metro station which has no parking in the morning and picking you up in the afternoon.
Sure, and as I mentioned in my comment, I agree there isn't much value to speculating what these unknown phenomena or technology are. But, the value to recognizing that there is non-zero probability that they exist prevents us from making overly confident statements such as "the reason we haven't seen radio signals from other civilizations is because we are the only intelligent species in the universe"
500 years is a very short period of time on the cosmic scale.
Erm, seriously?

Or do you only mean classical, newton physics?

Because as far as I know, (quantum) physic is far from explained. Shure we do know a LOT more than we did 100 years ago, but I doubt we have fewer questions.
I even suspect it can never be fully understood. Some basic principles, yes. But if the universe is infinitely big and small and it seems it is, there is no full understanding nor resolving all questions. I thought that mindset died out allready. Because before quantum mechanics etc. physicist actually did thought they allmost solved all questions. And then: oh. There might be more ...

I dunno. I think "auto-optimization" best describes the process.

Even calling it "learning" is kinda overselling itself. There really are only two camps of "Learning": auto-optimization (against a trained dataset), and auto-categorization (aka self-training).

Its auto-optimization: the algorithm self-corrects itself to try and look more like the training-set's "ground truth". Or auto-categorization, as the algorithm looks for patterns and tries to draw its own categories.

"Learning" implies model finding. Which... strangely enough... I'd argue that 3-SAT solvers are more "learning" based, at least with colloquial use of the word. Those things really do craft new theories and test them through the process of elimination / resolution / etc. etc. "Neural Networks" explicitly DON'T do this however.
Fair point, but this would still be less secure. Packages are generally signed by individual maintainers and as maintainers come and go, the trusted keyring evolves. It also puts the power of signing packages directly into the hands of maintainers, rather than granting access to a single all-powerful private key.
We don't have much of an option but to look with the tools we have, so though it's an interesting thought exercise (and continually worth pushing for new sciences) I don't think it's actionable to assume otherwise. E.g. I don't know of any generally-accepted theory that says that sufficiently advanced civs will definitely not use what we use, so it's still worth looking while we try to discover new things :)

I’m totally ignorant in this so my question could be half baked but what exactly are you saying?
