"Every tradeable ICO is really an unregulated security."

I disagree with this claim. It depends on whether the token constitutes an investment contract. If the token has utility, was sold as a utility bearing token (rather than an investment opportunity), and if the project possesses an open codebase which token holders can theoretically modify, then I don't believe said token is an unregulated security.

Yet, the vast majority of tokens do in fact function as unregulated securities, which is why these waters are muddled.
They kind of are a thing, there's the LG 43UD79-B[1] which is a 43" UHD monitor. Not the biggest screen, but decently sized and it advertises a 5ms GTG response time which should be adquate for monitor like use.

iMessage is more popular. You want people to use Signal, but if they don't want or cannot use that, iMessage is his preferred alternative. For a similar reason, I use Signal and WhatsApp. (All 3 are E2EE.)

The two roles are not comparable in my opinion. In most cases an instructor of humans has no capability to control the car. I've heard of some cases where they have brakes installed on the passenger side, but I'm not sure how common that is. I've never heard of a teaching car with full duplicate controls, though it's certainly possible they exist. I think even a bad new human driver is still better than an Uber automated system at the moment.

It also might be helpful to do the opposite. Write out what your life will be like if you continue down the wrong path or just let yourself go entirely. I think we all have some idea of what our lives would be like if we regress, I know mine would be especially terrifying. This way if you aren't motivated to chase your goals you will at least have something to run away from.

I'd argue Boeing (and most other companies) have the benefit of amortizating "fear" over the total installed base of similar technologies.

A Chevy engine turns out to have a design flaw, investors say "Yes, but Ford produces and sells tons of engines, so here's how much we think fixing it will cost."

It seems like the recent Uber / Tesla self-driving impact is more of the form of "Gee, maybe this isn't even possible."

If the V-22 Osprey tiltrotor were the only aircraft Boeing made... then I'd say it would be a more similar analogy.
Nope, any bitcoin client can verify any transaction very easily. (Bootstrapping by verifying every transaction in the blockchain does take a while though.) Proof of work is only to prevent a 51% attack where someone spins up enough bots to hijack "consensus" and rewrite transaction history. That's why the difficulty can be dialed up or down - most of the work in mining is not related to verifying the transactions.
It seems like with self driving cars, delivery just becomes even more commoditized than it already is. Not having to recruit drivers is just one less place for companies to have a competitive advantage.
Tritium. In addition to the points made by other replies, current fusion is (mostly) D-T, and we’re nowhere near breeding T in the reactor, so it has to be made in fission plants. Tritium is very expensive, and a significant risk for nuclear weapons proliferation.
Sounds like a good way to filter out a certain kind of users.
I'm not terribly sure its Uber. It actually looks like something to do with keeping the Governor happy. https://www.theguardian.com/technology/2018/mar/28/uber-ariz...
I think that's because it's currently not tracked. I.e., the station could have reentered a couple of minuted ago, and they wouldn't know.
Airplane autopilots operate in a completely different environment, in which planes' flight paths are set and monitored by Air Traffic Control. A plane on autopilot would never have to dodge a pedestrian, and would be separated from other planes by thousands of feet.
The reactor is ruined. No damage to larger area. Possible smaller radiation in the structure, since the reactor inside is possibly radioactive.

Call me cynical, but it sounds like designing the wheel sensors to tend toward not sensing hands on, increases the chance the company can use the narrative being used "driver received hands-on warning and (apparently) ignored them" etc.

False negative seems likely. False positive seems unlikely, maybe nearly impossible.
This specific presentation seems to work perfectly even if you replace all occurrences of "cryptocurrency" with "blockchain" and vice versa.
It's staggering to think that these bitcoin enthusiasts have never heard of M-Pesa or other similar systems. Note that these systems work with dumbphones, which is useful because (I believe) almost all of the mobile phone penetration in places like Africa are dumbphones, not smartphones.
Meta rant: I would like people to remind themselves that HN's rules explicitly disallow shallow dismissals. Unfortunately this comment section seems to be nothing but.

The material science behind high temperature semiconductors has undergone radical changes in recent years. The techniques being used are largely well understood science and the downsides of previous approaches like ITER are explicitly avoided. There has been a visible explosion of commercial activity in recent years.

People bander around the "always 20 years away" moniker as if we should put today's estimates on the same grounds as the guesses from those early 1970s projects that were never even properly funded. People were not screaming "20 years more" at the turn of the century.

You don't get to discount something as potentially groundbreaking as this just because it's taken a little while to get here. Either put up or shut up. I would love to hear genuine substantive conversations here, if people were willing to have them.
Which is the case for most people.
I think that, without the magnet, there is no such thing as a containment vessel for a 100 million degree plasma.
The whole cryptocurrency market is surreal to me for these reasons and many more.

But I did think the same thing about Twitter, especially early on when it was constantly broken. And yet, while it was broken people were still talking about it and it was gaining mommentum.

That's the parallel I see here. Enough of the right people are talking about it that it's going to be a thing for at least the near-term future. The whole eco-system can be flawed, but it has momentum.

And even among those that have been scammed, it's in their best interest to keep pushing the virtues of cryptocurrency as long as they have any left to sell.
If it's Maps then I presume it is aware of Google's knowledge / collecting of hotspots and is then able to guess where you are. Probably some other voodoo as well. Point being, even with location off you're still trackable.

ISP will be aware of all traffic to your IP, but consider that most people have their DNS set to use their ISPs, meaning the ISP easily sees this information in logs. Some people use Google DNS or another provider to bypass the ISP's DNS, which is a step better.

Now Cloudflare is providing a very fast and privacy-driven DNS, so to me this is a step up from others (Quad9, OpenDNS being formidable alternatives)

Say you're on a public WIFI and don't want DNS queries from your machine, there's also DNS-over-HTTPS (which Cloudflare and a couple others support) which doesn't use the DNS protocol and would make a POST request to say, https://1.1.1.1/.well-known/dns-query instead.

Also with HTTPS, ISPs won't see the full URL, just that a secure connection was made to that domain.

Except the thing that kept twitter around through the problems was celebrities. People following celebrities like Ashton Kutcher and Kim Kardashian and comedians kept it relevant until it became used in the Arab Spring and then it became “legitimate.”

I don’t see a parallel there for cryotocurencies. It’s just a bubble and I don’t see any Arab Spring type of event to legitimize it.
The problem is if you do business in tax free zones for example...
>After a while, reactor has to be rebuilt from totally new materials.

The closest parallel we have is nuclear reactors. Navy Nuclear submarines are probably the most prevalent safe small reactors (US submarine reactors not K19) and they have significant lifespans extending across multiple decades. (source: passed my navy nuclear engineer exam in a past career) The resulting embrittled can/containment does need to be handled safely, but this is a capital depreciation that can be modeled and planned for.
You can easily buy a high quality dumb TV in 2018. I just did it last year. It took me ten minutes of research. I saved hundreds of dollars over and enjoy many more streaming features than the equivalent smart TV by hooking up an old laptop via HDMI.

Until they have a working prototype, this is the equivalent of vaporware.

Moreover, it's not clear if they will have a working reactor in less or more than 15 years, it's not clear if they are building a research reactor or a production reactor, it's not clear if they are going to collect the heat and use it to produce electricity, ...

Also, the article say that:

> A newly available superconducting material – a steel tape coated with a compound called yttrium-barium-copper oxide, or YBCO – has allowed scientists to produce smaller, more powerful magnets.

but if I understand correctly the new material is just a new type of superconductor wire that is more efficient than the current wires, it is not a superconductor magnet. If they have better wires, they can make better electromagnets, but it is confusing. Also is not clear if they have tested the new kind of magnets or it is just a theoretical application.

Also, 15 years is a lot of time, usually it means they don't have a clear idea of how to solve all the technical details. https://xkcd.com/678/
iMessage is end-to-end encrypted, and a good bet that the app publisher is safe. Apple has a strong record of strict security and anti-government-snooping policy.
They are not the same. Yes, they all collect a lot of information, but only Facebook allowed much of that information to come into possession of third parties.

Are you targeting Anvil as a competitor to Django/Ruby on Rails? I'd love to find something better than Django, but closed-source + small community + the pricing model all suggest that I'm not quite the demographic.

I feel like most people who need a website to "take orders for your new widget, or keep track of your customers, or schedule your local football league" are best off just contracting it out. I'm not sure how this moves the value needle to make an average person want to learn web development.
iMessage is end-to-end encrypted as well.
Never lived in London, but I hated Manchester. So it's not necessarily "a way better" choice, but there's a choice, which is the point I guess. (I remember Newcastle fondly.)

So, essentially the transreal numbers treat NaN as a "value"?

"The main difference between transreal arithmetic and IEEE floating-point arithmetic is thus that nullity compares equal to nullity, whereas NaN does not compare equal to NaN."

Keeping Pygmy Sloths Afloat
I think it is possible that the Tempe police chief and mayor anticipated the incident could be a problem for them, especially given the secret agreement that later came out, and chose to try to spin the story on their own account. It is not hard to imagine that, in that frame of mind, they might be receptive to someone from Uber saying "clearly this was unavoidable", but I have no way of knowing whether any such conversation took place.

Then there is the question of whether the Uber-supplied video accurately represents the lighting conditions at the time... This may seem unduly conspiratorial, but I gave both Uber and the Tempe administration the benefit of the doubt until it became clear that the initial reports were innaccurate and less complete than they could have been.
The two people interviewed were fired for cause from this same program, of course they will have a negative opinion. One even fired for the same thing this safety driver failed to do.

>Both Kelley and the former driver in Tempe were dismissed from their jobs with Uber earlier this year for safety infractions: Kelley said he was let go after rolling through a stop sign while he was operating the car, which he disputes; the individual in Tempe said he was dismissed for using his phone while the vehicle was in motion.

Long to short, a couple years ago, I was out for drinks and bumped into a friend. She was having drinks with a friend who is a prominent researcher at Princeton Plasma Labs.

We got to talking. He assured me they were getting closer and it was only a matter of time (read: money). I'm not a politician or an investor, etc. so he had no motivation to blow smoke up my arse.

Less than a week later there was this:

Agreed, life is a lot more enjoyable when you don't worry too much about how you're living it wrong and wasting it.

I especially find the "you only get X weekends with Y" formulation depressing. It makes it sound worse than it is, and enforces a valuation that may not at all be true for you.
Assuming that path is actually viable, which is debatable, that path might have other risks. It's not clear a priori where the total risk is lower. IIRC, wind power has, for example, a rather high accident rate for workers. Impact on birds was also something discussed. Massive solar power plants in Africa, for example, have an associated political risk.

This will probably end up pushing us to Lithium fusion pretty fast, the fuel is a lot more common and the temperature requirement is only a little hotter.

That said nuclear proliferation from tritium is a lot less of a risk than from uranium. Anyone can put together a nuclear event with sufficient enriched uranium, pinching tritium to fuse using a fission event, well it's a significant technical hurdle.
It's actually an incredibly small amount of material that is heated to millions of degrees. It is a drop in the bucket compared to the amount of matter in the immediate surrounding environment, so the energy can be soaked up relativity easily.

I think I remember hearing something like that anyone more than 50 feet away would be completely unaffected (but don't quote me on that).
There are plenty of companies offering that for a price - search for PCI DSS compliance checking.

For DIY, then start with Kali Linux - you get the whole suite of tools but be prepared to do some learning and it is non trivial, especially if you are unfamiliar with Unix. You do get a mostly working OpenVAS with the Greenbone webby frontend nearly out of the box, but it needs a bit of config https://www.kali.org/penetration-testing/openvas-vulnerabili... is a bit out of date. Even once you get it working, you have to be prepared to evaluate the output.

Also bear in mind that security means different things to different people and different systems. There is, and never can be, a magic security bullet.

This is not a safe option, particularly on certain roadways. Accidents increase when you have a higher levels of relative speed difference between lanes of traffic. Having "turtle mode AI cars" isn't going to help us.

Speaking of the elderly.. they often end up in fatal accidents even at low speeds. Their frail bodies combined with strong safety restraints are not a good combination; particularly in the rear seats where their level of risk increases to nearly 2x the front seats.
Cloud flare showed their colors when they pulled down the political sites because their CEO interpreted it as hate. Cloudflare, you are zealots and are not to be trusted.
It is hard because of the TLS's pre-PFS legacy and to some extent also because of (very meaningful) intention to reduce roundtrips. The way to do SNI-like stuff is obvious: negotiate unauthenticated encrypted channel (by means of some EDH variant, you need one roundtrip for that) and perform any endpoint authentication steps inside that channel. This is what SSH2 does and AFAIK Microsoft's implementation of encrypted ISO-on-TCP (eg. rdesktop) does something similar.

Edit: in SSH2 the server authentication happens in the first cryptographic message from server (for the obvious efficiency reasons), and thus for doing SNI-style certificate selection there would have to be some plaintext server-ID in first clients message, but the security of the protocol does not require that as long as the in-tunnel authentication is mutual (it is for things like kerberos).
I've seldom seen any tweet carry information for longer than a few days. The combination of the messages being small, threads being hard to read, and tweets being hard to search makes them an atrociously bad medium to store information.

It's kinda like IRC discussions but almost worse. It's a shame because there's a lot of information stored in there... it's just not accessible.

As I understand it, even if an autopilot drops out completely and without, you have a reasonable amount of time to take back over -- worst case scenario you just glide, and you have a reasonable separation from anything else in the skies. With a car, if you go even 5 seconds without control, there is a good chance you'll have hit something. It's a very different environment and constraints.
I find it rather depressing how you got downvoted. That PG is speaking from a privileged background is kind of obvious, even if there isn't necessarily anything wrong with that. But most people don't get to manage their time much.
Predicting Google closures (2013)
The article feels like a corner case in social sciences. It's addressing the race as a social construct issue in the USA not a global question. It doesn't manage to address the issues (in my opinion) around when policy base on genetics might be good (rarely, again in my opinion) or not (overwhelmingly mostly, in my opinion)

It felt like the context was to discuss IQ. I find this chilling. I rarely see a role for discussion of IQ as a determinant.

When a geneticist says detectable DNA level differences exist I fail to see how or why that should inform anything of merit in selection criteria for governments or governing bodies. Other tests feel like a better basis. (Btw I refuse to do IQ tests and have no assigned score and have no interest in being ranked or understanding my rank, I am reasonably confident I am median score. I don't care if above or below the rough middle. I'd be as distressed as anyone to be found significantly below average and its false to argue there is a dichotomy here. Nobody wants to lag behind even if they espouse the norm as a statistical thing)

It might inform health issues in as much as testing drugs on white men is bad to decide how to treat asian women but then testing drugs on men is bad to decide how to treat women and children. And vice versa. Is genetics the main problem here for all drug testing? Or are basic drug test regimes possibly at fault? This to me epitomizes the problem. What do you want to do with this knowledge DNA can show we are sub species? Where is this going?

The article read like it was about the 'they are in denial' story and was left bashing. I think an underlying problem remains which is that racism is a cancer on society and feeding it with implied middle ground views ignores the toxicity of the problem. Society is about so many poles of difference, our racial identity feels like the least relevant. Do the police do DNA tests before shooting young black men?

Does DNA show race exists? Maybe. Does it matter? Only if you describe a problem in narrow ways to demand its relevance. If you take a different view of 'what matters' the DNA component of the story is far smaller. For me, the overwhelmingly important stories don't demand recognition of underlying detectable DNA distinctions.

(Obviously written from a left perspective)
