> transferred some BTC over from my Coinbase account, withdrew cash within 20 mins.

Fascinating. Somehow the ATM network was confident that it had your BTC and was willing to give you actual cash within 20 minutes. That suggests that either they don't care much about security or that what you actually did had very little to do with Bitcoin. Did you perhaps actually just convert Coinbase value to Hungarian Forints without really involving any Bitcoin transactions?

I'm not really trying to be snarky. There may be a genuinely useful economy based on companies like Coinbase that operate under different rules than your usual banks, but it's not clear to me that Bitcoin per se or, for that matter, blockchains, are an important part of this.
I think those are also mostly verse - blank verse is still verse. Although, as with all things Shakespeare, his use of prose and verse is its own subfield of study so I was able to google my way to some cold, hard numbers (in spreadsheet form, no less).

What? Let me give you an example. Gasoline has inelastic demand. If the supply of gasoline drops such that it’s below the amount demanded, then the price will rise to the maximum amount that people are able (not just willing) to pay, because there are few realistic alternatives for most people.

Same goes for housing. And in San Francisco in particular. Unless supply meets demand (which it won’t for a very long time), prices will be pegged upward. I can’t see prices falling unless demand decreases, although I’m as hopeful as you.
> I'd pay much more for something that could do signal integrity measurements on the cable as well.

And how do you propose performing such measurements for any less than the minimum 6-digit entry cost to acquire the necessary calibrated instruments for any meaningful test that might be considered proper?
It’s difficult for non-personal transactions in general. If you have a business that delivers some digital product, it is very difficult to serve an international client base without running afoul of anti money laundering compliance issues at banks and such. Cryptocurrencies can get around that. And I’m not saying there isn’t good reason for those rules for being there, but that they are stagnant and good candidates for “disruption” provided the attempts are made in good faith.
If bears were capable of warp drive, then I would agree with you.
For some it's better than others. I don't feel I gained a lot (besides some enjoyment, which isn't nothing) out of actually reading & seeing performances of Shakespeare, for example. A lot of that particular set of classics' importance is in the secondary effect of how it's impacted Anglophone culture, not so much in what you gain out of the original works (which to me fall in the category of, "they're fine, I guess"). Some other classics do admittedly have interesting or insightful stuff that you wouldn't have gathered second-hand from what's generally well-known about them, though, especially those where the secondary exposure is a bit less over-saturated.
> Somehow the ATM network was confident that it had your BTC

It is fairly simple to verify this. By this time (20 minutes), it would have had 1-2 confirmations, which is sufficient for small amounts.
I think it should be allowed but the tests it should pass must be far more strenuous than for traditional software. I'm happy with failure rates of around 1 catastrophic failure every million hours. Even humans sometimes fail catastrophically and black out at the wheel for no detectable reason.

That level of testing is well beyond what today's software and hardware is capable of. Waymo has to override their cars (disengagement) approximately every 6000 miles [1] which equates to about 200 hours of driving. To reach a confidence level of 1 in a million hours you would need a test fleet of a thousand vehicles operating for a whole year without any incident occurring that requires human intervention. The costs for such testing would run into the hundreds of millions of dollars which makes me feel like only the largest corporations in the world could develop this technology.

Here in Australia we already have cardless cash from own-bank ATMs.

If you still have your phone, or access to a computer to log in to internet banking, you can get a couple of codes to withdraw a preset amount from an ATM.

Banks, globally, are going to offer these services well before they let their lunch get eaten.
This seems like it would only work for similar languages (i.e. romance languages), in that it depends on the embeddings within languages to be similar.
How does this preclude it from being overly difficult or costly?
Yes, but probably only in general (meaning only from a theoretical point of view without considering external forces)?

E.g. as soon as the cable has headwind (in the opposite way of the planet's rotation) the cable would slack off, the thing in orbit would slow down & lower its altitude (how much? Would it anyway have to always skim the upper atmosphere?) => then as soon as the cable gets tailwind the opposite would happen, with relative slingshot-effect.
As far as I know, most RDBMS are connection based, which brings an overhead. When you got your connection they're quite fast.

From Wikipedia's "grammar" article:

"Outside linguistics, the term grammar is often used in a rather different sense. In some respects, it may be used more broadly, including rules of spelling and punctuation, which linguists would not typically consider to form part of grammar, but rather as a part of orthography, the set of conventions used for writing a language."

In common usage, punctuation is often considered part of grammar. This matches well with the computer science meaning of grammar (rules for parsing), because punctuation can change the meaning of a sentence.
Doing something like this has the advantage of reducing the distance between reader and the translator or the author, but at the same time removes context. If it’s a high Victorian translation of a Greek text, what you’re reading is from ancient Greece, but given a Victorian cast, with all the ideological implications that brings with it. I’d rather you didn’t remove that context, but I can see why you’d do it.

Fantastic project, anyway.
Yeah, but gold is real, it's a real metal here in the physical universe, not only does it look good, it doesn't tarnish or rust ( to any real degree under normal circumstances ) with many niche uses beyond ornamental, just think about how much gold foil goes into something that's going to space... it is also one of the heaviest, most uniquely workable metals that isn’t dangerously radioactive.

My point is that it has an INTRINSIC value, not just an arbitrary value we've assigned to it, but a natural value that comes only to things that are actually naturally valuable... that statement may seem to be self referential, i.e. wet because not dry, but I think it makes the point I'm trying to get across, which is: there's a difference between that which IS valuable, and that which has value because WE assign it value.

Like tulips in pre-crash 1637, "bitcon" only has the value we assign to it, in reality it's nothing but numbers and we've plenty of those.

That it can and probably will decrease in value drastically when a majority of people realize it has no INTRINSIC value... well that should be warning enough to those wise enough to think about critically.

It's not like "market cap" really even applies to it here, yes each "coin" is assigned some value and the multiplication applied methodically does seem to come up with a giant number, but there are no REAL assets... it's not like it's a share of stock in a company that makes anything, it's all ethereal, there's absolutely nothing of value except the fact that somebody else is willing to exchange something of REAL value for it... when that's gone, the whole thing will be another story on Wikipedia...

I took a picture, here is the ATM that I used - https://imgur.com/bpwmBLz

I was also worried about the conversion and the rate and fees but in the end when I calculated, it was barely any different from the spot price on Coinbase at that time.

Honestly the ATM could've been a bit more clear on the fees and the rate, etc. But I was quite happy with the service.

> Blockchain advocates have yet to prove that the underlying technology can live up to the grand claims made for it.

I agree with this sentiment. Since blockchain was introduced I have seen many people building solutions on top of it, but not many people actually using those solutions. Instead, it seems that the most prevalent use of blockchain technology or crypto currency is to boost the speculative wealth of their stakeholders.
A pointed comment in that discussion: https://news.ycombinator.com/item?id=9881946
They did show their theory. They didn't really show supporting facts. If you claim "it's caused by something different than we see everywhere else" you really need more than "it's true, because money".

I knew that something like this comment would crop. It's a damn shame: there's a great deal of complexity, elegance, and meaning in the world, and choosing to see literature through the hateful lens of power dynamics robs you of the change to see this beauty. One of my hopes is that we return to teaching the classics as timeless universals.
Yes, Gasoline has inelastic demand.

That means that if supply drops, then price goes way up.

Now think about the reverse direction. IE, if supply for gasoline goes up, what happens to the price? prices goes way down.

Inelasticity of demand means that price will change a lot, if supply changes. Supply goes up, prices goes way down. Supply goes down, price goes way up.

If housing has inelastic demand, that means that if we build a small amount of housing, then price would go down a lot immediately.

People talk a lot about the idea of "pent up demand". "Pent up demand" is the idea that if price changes, then a bunch of people will move to SF to immediately live in those new homes. That is an example of elastic supply.

Inelastic would be the idea that nobody at all would move to SF to live in those houses if we built them, and they would just sit empty.

If your system relies on people going against their incentives, it's going to produce substandard outcomes. While some tech workers did decide to take pay cuts to work at USDS & 18F, most didn't. I considered both, but then I realized that best case I'd make 1/2 as much as my current compensation. On top of that I'd be fixing or replacing legacy code, not developing skills that would be useful elsewhere. I have a sense of civic duty, but it doesn't go that far. I'm sure the same is true for many others.

The net result is the same as if the government paid mechanics or doctors substandard wages: Some good talent would join out of civic duty, but the overall effect would be to lower the quality of workers relative to the private sector.
but it's now clear to me that the state and local governments are too incompetent to fix this problem.

Don't forget NIMBY residents. Just down the street from me is a building that used to be a church. The church wanted to start providing services and shelter for homeless LGBTQ teens. The neighbors threw a shitfit, the shelter never happened, the church closed and moved, and now the building is a dentist's office.
I think it's mostly a problem of context and relevance coming from lack of independence in young people today.

When I read a book, it's because I have chosen to read it, I know something about it, I know where it belongs in history, and I believe it either has some relevance to me or I think it will just be entertaining to read.

When a teenager reads a book, it is often assigned, meaning that they do not know about the context of the book, it's often not at all relevant to their life, and is assigned by instructors they might already be inclined to distrust and disrespect. Sometimes the situation is made worse by certain forced critical readings of the book, or a ban on criticizing the book.

I'm not sure calling people who are constantly assigned arbitrary tasks they have little say in and whose bathroom breaks are controlled "emotionally immature" is useful or accurate, and is close to the root of the problem itself.
I started eating one meal a day a few weeks ago. At first I had huge dinners but they’ve tapered off a bit and are now substantial but not crazy, and usually a small snack an hour or so later depending on how I feel. Combined with morning body weight training / running (which feels awesome when fasted) I’m really enjoying it. The few days when I’ve eaten during the day have left me feeling heavy and bloated and the hunger during the day has gone. It’s very doable.

>Is the cost of calling the other function negligible (e.g. the functions are called rarely)? If yes, feel free to do it.

The question is more one of errors, I think.

You pump your results in a queue before you let another function do the next step, if one function fails it's not the whole process that is lost.

Step Functions, for example, lets you chain functions and does retries for you if one function failed.
That's certainly possible. It may be that we've lucked out so far, and are about to hit a wall, where things get more and more complex.

Another possibility is that developing the next level of theory, and finding a way to simplify it mathematically, are two different steps.
Not only does it run Android, it has built-in HDMI mode, where you can just connect it to any HDMI port as a second screen. It will act as any regular screen (except it's e-ink of course). This way you don't even need a Termux or bluetooth, or whatever, instead depending on your setup you might just connect it to your PC and run any software you want as on any regular screen. (The screen refresh will be somewhat laggy of course, but they really did a great job in this one, and many regular apps are truly usable.)
I've always thought that before forcing us to read a classic they should get us to attempt writing one (or, more realistically just a few pages). Get us to create a relatable character, come up with an engaging and original plot, describe a place, a situation or a character in a clear, concise, amusing, manner. Get us to realize first hand how difficult it is to do so. Then you have my attention. Now I want to know how the best do it.
Large scale landlords actually want to invest in more property. E.g. the apartment building I reside in was built only a few years ago by a publicly traded REIT.

It is nativist homeowners that oppose new building because it reduces home appreciation and brings traffic and ethnically different people to the neighborhood / city.

I don't know how familiar you are with Bitcoin's Lightning network, but it works. You can send satoshis in milliseconds.

The term "trustless" doesn't imply that you don't trust the system. It's the idea that a "trusted" network can emerge from a system with a mix of trustworthy and non-trustworthy nodes.
Of course. We do not change punctuation, with a few exceptions for some short-lived archaic constructs like comma-emdash.

We do change from single-quoted British style to double-quoted American style, but I think most everyone would agree that that is merely a presentational change that does not change the actual grammar of a sentence. (And that in and of itself was a very common thing for editors to do going back hundreds of years too!)
Is it?

My experience of innovation is that it tends to be a singular affair. Not a result of group hangouts and all day brainstorming meetings but the result of a single unreasonable person who is seized by an idea that's either not obvious or - more commonly - something other people were aware of but didn't rate much.

I don't see why you'd need physical proximity to innovate in that way. Unless by innovation you're referring to product development generally.

On another note, a vast majority of the targeted use cases would benefit from well engineered solutions; having redundant persistence, availability, immutability, ordering, tamper-resistance, non-repudiation. But all this is could be simply achieved with Kafka + PKI signing.

Anyway, hyperledger fabric uses Kafka internally for the ordering... which leads me to say:

If lighting candles in the dark and saying 'blockchain' 3 times is all it takes to make a VC appear and help you build good Kafka + PKI infrastructures to tackle real problems; then I'm all for maintaining this white lie based on all the wrong reasons (which would attention seeking? unspoken implicit promises of riches?).
