I won an essay contest in college that NASA set up regarding the future of supersonic and hypersonic aviation.

Even back then, supersonic, let alone hypersonic, aviation was such a pipe dream for civilian aviation. Not saying it can’t be done, but I can’t imagine the breakthroughs that need to be made would be made outside of any context short of a World War.

Let me list the problems:

1. Materials Science. Very hard to design materials
that survive those kind of stresses, and that you know will last 30+ years. Airplanes routinely have 60 year life cycles, so 30 years of material survival is the minimum. The stresses on these things are huge. The Concorde would actually expand 10 inches from head-to-tail during flight because of the heat.

2. Overpromising dating back 40 years. My favorite example is Ronald Reagan promising an “Orient Express” that would be 90 minutes New York to Tokyo. That was in his 1986 “State of the Union”.

3. Acceleration. Flying Mach 6 is one thing. Having a plane that can accelerate up to that speed fast enough that the flight doesn’t already end, AND THEN slow down an equal amount, is another thing.

4. Sound. This sounds like a nuisance thing, until you hear one of these aircrafts in action. THEY ARE SO DAMN LOUD. It’s a health and safety issue almost. I would compare it to being around artillery fire, maybe worse. It stays with you for days.

The Japanese and Australians from time to time do some good work on this kind of aviation. Boeing had a civilian supersonic project in the 70’s, but it’s all been given up except for the occasional private jet or military experiment.

I built a batch script to automate a lengthy process we had to do to a few dozen offline computers. I had field techs telling me it ran but didn't work. Found out that they were not reading the output of the command line. It would ask them to run it as Administrator. Quick fix, I made the box background go red and the text yellow when it hit this issue and never had a problem since.
This makes sense, one is far more focused on precise articulation of a prepared score, while the other is focused (in large part) on improvisation.
That is a good question, and I've thought about it a lot. There seems to be a growing group of people who think it's okay for minorities to discriminate against the majority in order to gain more power, but I'm just not convinced that it's the right way to correct social imbalances. I think that it would lead to everyone both in the majority and minority feeling persecuted. I think this would fuel and maintain hatred and disdain between groups instead of finding a way for everyone to thrive within a single group. If you disagree or see a flaw in my thinking, please let me know.
I had a lot of fun in the lojban community back around 2003 - 2010. I attended a few jbonunsla, and that community is where I made the professional connections that lead to me moving to the Bay Area.

During a recent conversation, I realized that a lot of the community dysfunction there is the typical contrarian trap: If you're doing something sufficiently unusual, the vast majority of the people who show up to work on it with you are going to be extremely opinionated contrarians more-interested in personal experimentation than in working to make something solid and accessible to a general audience, and not particularly interested in cooperating or otherwise working together. Most of the people who are interested in pragmatic applications are going to just use something already widely used. The lojban community, when I was active in it, had a huge variety of interesting ideas that nobody was ever following up on or implementing, and the big projects people agreed were important (completing a document standardizing a new version of the language) languished. There were pretty regularly complaints about the community infrastructure (website, wiki, mailing list) that were answered with "If you're passionate about this, please feel free to fix it, or take over running it yourself. I want to hand these off and stop being the only responsible person. I'll give you commit access, root access on the servers, etc." that were almost never actually accepted.

So, basically like almost every open-source project out there. ;)
The average person defines trust very differently than the average hacker, Hacker News reader, crypto-anarchist, or Ethereum developer.

For the latter group, trust means that mathematically nothing can go wrong. Everything is cryptographically proven, and short of being able to factor large primes, there is no logical way for the protocol to result in an incorrect answer, and no central authority that can abuse its authority.

For the average person, trust means nothing has gone wrong. When you first encounter a stranger, you open up a little bit, trust him with small secrets or small tasks, and see what happens. If she doesn't abuse that trust, you entrust her with progressively more vulnerability. Once someone or something has a long-time record of being in a place where they could have abused your trust but did not, they're considered "trustworthy".

For many people, Uber is still a trusted third party. Ditto Facebook and Google. For most of the media, they're not, because Facebook and Google together fucked over most of the media in a pretty large way. But half of America - and much of the rest of the globe - doesn't trust the media anyway, because the media's story is unrepresentative of their own lived experience. The average person determines who to trust on their own, irrespective of what the math says. For them, the fact that Ethereum has been hacked even though mathematically it can't be hacked is a big strike against it - unless they have another reason to trust it, like having made a whole lot of money speculating in it.
Have you read Grant's other books? So far I've read Sell or Be Sold, The 10x Rule, If You're Not First, You're Last and Be Obsessed or be Average. I've found all of them to be pretty good. Not necessarily life changing, but solid, with a good mix of motivational message and some actionable ideas. Enough so that I'll probably go back through and read a couple of those again and actually take notes this time through.
Did they choose "wrong"? No. Did they make a choice and move on? Yes.

> At this point there's waayy too many actors and people who want Bitcoin to succeed

This has no relation to whether something goes to zero (or practically zero). Political influence? Sure. But I don't think anyone expects D.C. to bail out Bitcoin.

> A company has a "single point of failure"

Companies trade after bankruptcy. There are stubs, practical and theoretical, for companies improperly wound up going back decades.

Even if a state says "XYZ failed to pay franchise taxes and is now inactive," a shareholder can sue the former directors, holders of proceeds from the company, et cetera. (Company "ownership" is de-centralised and ambiguous, a fact that becomes uncomfortably clear post mortem.)

Colloquially, we call "practically worthless," i.e. where the cost of valuing something is likely more than it's worth, zero.
it is illegal for him not to accept the national currency

According to the United States Department of the Treasury’s site[1], there is no federal law requiring that businesses accept currency or coins as payment for goods or services.

How much are cryptocurrencies are used for actual exchange of goods? I.e. for actual shopping and commerce? Because it seems to me that the most prominent group of users are investors and miners; i.e. those who only buy, stack and sell crypto coins, and those who produce them. And I've read here in some past threads that it's not that easy to liquidify your crypto coins.

People have wanted to do the same thing in Washington state, cut it off at the Cascades say. To avoid moving the electoral college, you have to split into 3 states for almost always one way states. But the other parts of the state are sucking down revenue from the populated area to build their infrastructure. I almost wish it could happen, because then we would get away from the 60% of the state in Seattle votes for something vs 40% of the rest. We could just build our own damn infrastructure and not have to negotiate with someone with very different world views, who has very different needs and ideas about guns, god etc.
> On March 11, a day after Waymo filed a motion for an injunction against Uber, Wong describes Levandowski texting her to say he was bringing his boss home with him. Half an hour later, she says, Kalanick and Levandowski arrived, bringing with them a white bucket containing circuit boards and lenses, as well as legal documents for Levandowski to sign. She writes that Kalanick spent about five hours at Levandowski’s home.

Amazing. C'mon, she's heard you screaming on the phone to your lawyer. They know your last name. They can google you.

If I was working for this guy, and I observed the stuff that was going on, I would start talking to a lawyer too.
Smart Cities May Be the Death of Privacy as We Know It
I'm a woman that's worked in tech since 2011... at times the discrimination and treatment I've faced has made me want to quit the industry all together. But every time I reached that point I thought - no, I'm not the one who should have to leave, it's the people -- usually men -- who have not shown empathy, kindness or compassion. The ones who have bullied me and harassed me and made inappropriate comments or advances. So many of these experiences I just buried inside until I was in the company of other people I trusted and felt safe to share. There hasn't really been an online forum where I felt safe to have these conversations until now. Now that Leap is here I have other people who get me who I can talk to about the stuff that is bugging me. With their help I can treat each day as new and keep moving forward with my career. If you don't understand why this community is important perhaps it's because you have had the privilege of never feeling like a second class citizen in the industry you work in.

Would be interesting to see something similar and also fulfills the goals of meaningful work.

Perhaps with smaller companies this would work better and not conjure up ideas of digging and refilling holes on some soulless corporate farm.

Imagine a single-person company that sells homemade organic jam at a farmers market. As a one person doing everything, surely this person is overworked and couldn't possibly think of hiring someone until years later. What if this person was part of a program that allowed them to hire from a pool of candidates where the company pays a portion of the wage and the gov program subsidizes.

This person hiring really needs the help. The person being hired wants the job doing fulfilling work. The money assigned for the person through UBI is reassigned to this program.

Probably just a pipe dream, but could be similar to the incentives companies get for hiring ex-convicts, etc.
> If it takes two people turning two keys to launch a missile, shouldn't it take the same to send a missile warning?

Hell no. A missile launch involves a large expenditure of resources, and (sometimes) lots of destruction. A missile warning should not.
It's absolutely true that if you do everything correctly, a JWT implementation can be secure. Generally, in crypto engineering, we're looking for constructions that minimize the number of things you need to get right.

Why do you want to be included? What would be the point of it if you were?
My dumb friends can go get defrauded all they want, but if they know it is a bubble, and know they are mostly likely in the gambling unINformed losers end of the deal they will probably only get defrauded and gamble with what they are willing to lose. Like going to a casino.
> If you identify as a woman and are interested in joining Leap

You, as not a woman, are not being included. This is very different from exclusion. It also does not make any comment about male-ness equating with bad-ness; ironically, you are the one bringing in the idea that membership/non-membership in a category involves a quality judgement.
Good news. Seems they have removed "high-memory droplets"
Ask yourself what exactly is behind that “~550B”. The answer is nothing but faith.

You are comparing the market cap of cryptocurrencies to NASDAQ, a portfolio of the highest profit driving, real asset laden companies on earth. How is this even remotely realistic?
Totally agree -- but verifying a session token doesn't even have to be a database call. Put the token in memcache or redis; now, if you are so successful that a single network call that doesn't touch disk is your bottleneck, well, you can hire some very smart people to fix that for you.
A null-terminated representation is as close to a fundamental datatype for a string as possible. It is same in spirit as other fundamental data types in C like array. People have built abstractions over these fundamental datatypes over the years.
>A group does not "want" anything.

I disagree. A group of women is saying they feel marginalized and want to develop a community of support. Men, particularly ones in this awful comment section are saying "NO FAIR!!!" Those seem like groups, and they clearly want things.
I wonder how much money they spent for this...
For many users (i.e. desktop) bandwidth is something you're throwing away if you're not using it. I'm not saying this is a good idea in all cases, but it might be in some.

I might have exaggerated / misspoken in saying that, but at the same time it hinges on you trusting that the manufacturer is A) telling the truth and B) that device has not been compromised. It is fair to say that it is always listening. Also possible, is that a device positioned in the kitchen helping being used to lookup a recipe could overhear a sensitive conversation in an adjacent room.
Worth keeping in mind that the security cost here is illusory: the track record of length-delimited data structures isn't much better than that of ASCIIZ, especially since integer handling in C is so treacherous.
I have discovered white nationalist groups who believe that other races are not inferior but merely different and thus they wish for a society where they are excluded. Does that foster hate?

Generally speaking, when you sue someone, it's often in your best interests to give them an opportunity to settle, instead of going to trial. You often do this by listing all the awful shit about the other person that you're going to air at trial. We don't call that a 'Legal way to blackmail,' and neither is this.
What ethical rule do you see that breaking?
What exactly are you sharing? It's not illegal to be an asshole. It's also not important to anyone that you knew him years ago and think he's an asshole, so where is the schadenfreude coming from?
It's easy to design a system like this where the actual link isn't available client-side, and the server doesn't need to wait on a DB read and write before responding to the client: make the URL parameter be the destination URL encrypted so that only the server can read it. That kills the need for a DB read. Then the server can respond to the request before the DB write finishes since the integrity/consistency of that write is likely less critical than the response time.
That's a great question!

There is great interest in supporting multiple kinds of databases and this is something we will actively work on in the coming months.

SQL is a great general purpose data store, but there are certainly cases where you need a more specialised database. In Prisma we introduced some API changes to simplify working with nested data structures. An obvious next step is to use MongoDB for documents while keeping SQL for relational data.
I would prefer that the government control the supply of money and take a part of a preset emission to fund itself.

A second part of the emission could be used for UBI protecting the poor and getting buy in from the populous.

It would rid ourselves of the debtor's prison and the government would no longer be providing a yearly negative reward signal to it's financially successful citizenry.

Oh well enough fantasizing, time to guess how to report income tax on low liquidity asset income that hasn't, and sometimes can't, be liquidated. If I'm wrong it's time for bank account freezing and fines. Maybe jail time if I upset the wrong employee.

Agree. Too big to fail is a terrible, copy-pasta argument that makes no sense.

The combined worth of all the crypto-currencies put together is a drop in the global-financial bucket. The only people who would be hurt by a collapse to zero are those trying to artificially pump the price to cash out rich.

I used to be anti-FUD, but whatever the term for the opposite is - it's way more infuriating.
An elegant demonstration of the Pythagorean theorem
So many people love to parrot the 'It'll go down to zero!' line, especially if they don't have skin in the game, but there's pretty much no way. Specific cryptocurrencies, sure they could potentially go to zero. I'm watching one right now that's looking pretty darn close. But this entire industry? I don't think so. It's too late for that.

Too many players, too much ease of access, too much of the potential has been demonstrated at this point. Could it go down 50% or more still? Yeah possibly. I sat through 2013-2015 when Bitcoin had fallen from $1200 and got stuck in the $180-$300 range for two straight years.

I don't think that's going to happen again, not least of which because there will be people like me that would be happy to buy and hold until whenever it goes back up again at that price, but sure, it's possible.

But zero, or close to zero? No. Even this guy's example of his company was only one company, not the entire stock market.
What would the ethical thing to do be? Most people, especially housekeepers, can't just quit a well paying job without first making preparation for their next steps. If your employer is committing crimes and possibly implicating you in them, you might want to stick around to make sure that you have enough evidence to take them to court. Especially if they're a lot richer than you and have much better lawyers.
