>No they don't. Savings is only a number in a computer and lending is not limited to the available savings because private banks create money when lending. So, the quantity of savings have not effect in how much financial capital can be invested in the economy.

If that were 100% true (there is a caveat) then the ideal savings rate would be 0% and that would be truly awful for every entity in the economy regardless of whether they are companies or private individuals. All savings would become excess savings and interest rates would need to be in the double digit negatives.

In practice this would actually run into a contradiction, if the savings rate were 0% that would mean all income is immediately consumed or invested, meaning the economy runs at full capacity at all times, any increase of the monetary supply would immediately translate into inflation because all goods that are being produced are already being consumed, the additional money would result in additional consumption that causes a shortage of goods which then translates into increased prices aka inflation. At some point you would run into the physical limits of the economy.

As your savings rate is 0%, the amount of money that can be created without inducing inflation is also $0. The potential for lending is "effectively" limited by available savings.

The problem with the last mile is that there’s a lot of them. Even more if you’re in suburbia, where the number of people living in the last mile is comparable to people living in the last block or so in the city.

As much as I enjoy always pointing out things that we do better in the EU, unfortunately the situation here is opposite. Sending a letter from say Germany to France is a complete black box. Even with all the "priority" /airmail whatever stamps it takes 2-3 weeks on average. I understand this is different countries and all, but courier companies have it figured out. I could send a parcel with UPS from Poland to Spain using their cheapest Standard service and it will arrive in 2-3 days. Send the same parcel with national mail and it's any amount of time, with very little reliable tracking.
I think if someone downstairs asked me how far away the airport was and I answered in Kilometers or Vests they would be a bit annoyed.

It would be cool if everyone used SI units but they grow up with local tradition.

Even if you could convince everyone to move there are lots of locale features that don't really have an international standard most people know about. ISO doesn't even have a suggestion for which radix you should use and says both the American and British radix is fine (which is bad since they're mutually incompatible the way they're commonly used.)

For anyone old enough to have watched the original 1987 Verhoeven RoboCop, surely the word glitch is permanently associated for the hyper-violent scene where the enforcement droid ED-209 is demonstrated as a massive fail, only to be summed up by the project owner as a “glitch”. A scene that was outrageously violent in the theatrical release and even moreso in the director’s cut.

I know Verhoeven’s perspective was to use violent satire to speak about fascism, and the increasing militarization and technology-adoption of police forces — themes that are even more topical today.

I think your description of how glitch is used today, as a folksy (and ultimately dishonest) non-threatening way to describe a failure while stressed-out engineers scramble to prop-up a half-finished system, directly captures the ED-209 scene — where people seek to mislead about the true situation through the use of the word “glitch”.

The most frustrating issue with web development is fads. Every month there's a new must have technology that spreads with the most powerful marketing technique: FUD - fear, uncertainty, doubt.

"Did you hear about AMP? Yeah we switched to it last week. I heard Google would start weighting pages that didn't use it down. Wait, you haven't made the switch yet? Well... I don't know, we'll see what happens..."

If I smell FUD as a marketing technique, I'm out. The odds that you're trying to sell me something I don't need are astronomical -- and in four years, management will be driving me to the next big fad under FOMO.
That would imply that "foo(x: int)" is a string rather than a function.

Haskell doesn't use that notation either, it uses -> both for the parameter list and for the return type, and separates argument names (arguably, these are poor choices, since currying is not an efficient CPU-native operation and not intuitive so distinguishing between multiple arguments and returning closures is useful, and argument names are useful for documentation).
> read: other chains are centralized databases that have no business being blockchains in the first place and can be replaced by single mysql instance.

This, too, has been a thought of mine, but I'm not exactly sure how I would block diagram the 'locking' mechanism for the MySQL instance.

I've come to believe the locking mechanism is the nonce produced to sufficient solution parameters that appears to use the difficulty of finding said solution as its defensibility.

So how do you get the 'strength' of the miners throwing ExaHashes at a solution with a single instance? We could easily snapshot the DB and sign them, however, the point of failure is no longer in a 50% attack, but in losing said key... which intuitively feels far less secure?

> without the most remote hint of warmth

I’m struggling to work out what you mean by “warm” here. By a musician’s definition, low impedance pickups and solid state electronics (usually those with input transformers) have produced some of the warmest guitar tones on record. Even a mid-tier archtop plugged directly into a solid state amp produces _incredibly_ warm.

Distortion (in the musical sense), sure.
I'm not sure, I haven't been actively involved in development for a couple years.

There were a couple distinct activities. One is the rolling utxo hashes, which has no major engineering hurdles, and can allow a compromised security "bootstrap from a utxo set".

The other are schemes that allow nodes to not have the utxo set but still validate-- these have historically had unfavorable IO costs, and the bandwidth storage tradeoff hasn't seemed that appealing-- e.g. would you find reducing storage from 10 GB to 1MB but at a cost for increasing bandwidth 10x to be appealing? In some applications it would be, not others.

I believe work related to both has been ongoing, however.

Society is not maintenance free, and the institutions and services society depends on are not maintenance free either. The Postal Service, like many services that we depend on in society, are just assumed to always work because for years and years they did work. Yet we allowed improvements to be delayed, allowed leaders in who acted in bad faith, and the result is an service that is substandard by it's own measure.

What's the answer? Commit to do the work necessary to turn it around. The mail hasn't changed over the last two years in some fundamental way that makes it disruptive. Investment in the system was simply deprioritized. We know what the system needs, so let's just do the work. We need the Postal Service to operate as it should, as it's a key piece of infrastructure that society depends on, whether we recognize it or not.

Experienced guitarists can and they have videos all over YouTube. Most common giveaway? Aggressive pick attack. Valve amps and modeling amps respond in subtly different ways. They also respond differently to volume - that's important for guitarists who set their amp near the breaking point and use the volume pot to control their tone.

Having said that, for the average bedroom/small gig player these subtle differences are too minor to bother with. Especially when a modeling amp can accurately emulate so many different valve amps. Sounds good and you can save a lot of money!

BUT - I would be remiss to say that you shouldn't own at least one valve amp. Take the one you emulate the most and buy it. You'll be happy!

You're not thinking widely enough. The following is not the real story, just an hypothetical example:

You're Codake, a company that sells chemical photography materials.

Some person invents digital photography, you find out and buy the patent from them for 500K.

Digital photography would hurt your profits so you just sit on it for the 15 years, maybe start designing some products around it in the last 3 years of the patent to be ready for when it expires.

You made more money and society lost out for 15 years, all because the inventor probably wasn't used to seeing large checks and didn't shop around when the largest photography company offered them more money than they ever saw in their life.

Even the inventor got screwed, by selling the patent they got a nice house even though it was probably worth hundreds of millions.
Hello new paradigm.
Its not cheaper. You are not seeing the hidden costs which are subsidized via taxes. In the US gov workers retire MUCH earlier than normal working people, this creates a huge financial liability keeping up with decades of pensions.

I was an ebay powerseller and dealing with ups was always far better than usps, many times by a big margin.
Is it still cheaper if you factor in the tax dollars used to subsidize it?
You'd have no hope of ever exploring that universe though. Decelerating from 0.5c isn't really practical with any technology that we're pretty sure actually works. Sure, you'd see the rest of the universe on fast-forward, but you'd never be able to leave your own solar system.

Working in Toronto I found the same. Worse still (and in typical Canadian fashion), people would act as if they wanted to be more than work friends, but outside-work events would never work out for some reason.
Moving to the Netherlands fixed the problem for me, so I think there are strong cultural forced at play. I've found building friendships (and knowing who is actually not interested in friendship) much easier, in and out of work. Also, in one year my professional network is far better than what I had in Canada after six years.
The biggest reason for shallow work relationships is high turnover.
- Well, imagine what would have happened if AWS closed overnight. It would not only affect the economy, but also governments that run their infrastructure on AWS.

- What I meant by that is also the money can ensure that new laws are not introduced, or investigations not carried out. Have you seen reports of Amazon Basics, where they ask sellers to hand over their leads and then months later Amazon introduces pretty much the same product undercutting the seller? I would imagine if that was done by a small company, they would have been closed down. Yet when you are big, anything goes.

I thought this was the norm, not the exception. I'm not in touch with of my past colleagues anymore. Reasons: a) we never hanged out outside the office (besides, beers on Fridays from time to time), b) changing jobs usually means changing cities, and using Twitter/WhatsApp/Facebook/Email is something that I find useless if you want to keep in touch with people; for me it is in-person hang outs or no touch at all.

You can, and you’d be 100% correct.

It actually annoys me that we still teach kids that the Earth revolves around the Sun and the ancients with their silly earth-centric system were wrong. Just the math is (kinda [1]) simpler, thats all.

First, its a lie. And second it breeds contempt for the ancients that said and discovered many great things. I dont mind telling them that heliocentism is a great (amazing) approximation. But I really dont appreciate how from K-University previous work that has been outdone is dismissed [2]

[1] the higher order terms are sill there in the heliocentric system, they're just smaller in magnitude.

[2] Another example is atomism and how the physicists who rejected it are mocked in undergrad classes. Those guys were bloody titans and their models and methods are the cornerstone of modern engineering (try designing a bridge w/out continuum mechanics but using MD)

Mind blown; "It must be thrilling to live on a planet orbiting one of these ejected stars and to witness its trip through space."
Modern cryptography is about a lot more than sending private messages over public channels. The entire field of secure multiparty computation is about mutually distrustful parties participating in a distributed computation of some kind. Bootstrapping trust from "nothing" is part of that, and the theoretical work in that field establishes the limits and feasibility of accomplishing that goal. There are settings where "trust from nothing" (more precisely, when only one party is honest) is possible to achieve with cryptographic security -- for example, if aborting the protocol (stopping the computation) is an acceptable outcome (this is unavoidable if there are only two parties).

"Honest parties have the advantage that it's easier for them to agree (and they are rewarded for agreeing)."

I should clarify that when I used the term "advantage" I was referring to something analogous to mechanical advantage. A basic tenet of cryptographic security definitions is that the honest parties should have an advantage over the attackers in the sense that a small increase the work done by the honest parties results in a large increase in the work that must be done to attack the system. Note also that cryptographic security definitions assume the opposite of what you said: that the honest parties are not coordinated and are operated independently, but that the attackers do coordinate with each other (in fact we just refer to "the adversary" which has full control over all the attacking parties, with full access to their internal state, inputs, outputs, randomness, and whatever else).

You mention incentive structures, but incentive structures are not very reliable. You need to make a lot of assumptions about motivation before an incentive structure makes sense, and those assumptions can easily fail because of something external to the system. What if a group of miners who collectively control 51% of the mining capacity of Bitcoin realized that they could open short positions in Bitcoin futures and make a fortune if they triggered a panic by e.g. executing very obvious double-spending attacks? Historically incentive structures have failed to prevent wars, crime, and other unwanted behaviors.

"Bitcoin might become more popular and therefore might have bigger security demands"

One does not follow from the other. Security requirements have nothing to do with popularity and everything to do with the ability of some attacker to succeed in attacking a system. Even if nothing about Bitcoin changes, a change elsewhere in the world may create an opportunity to profit from attacking Bitcoin (and there is no reason to think anyone other than the attacker would be aware of that opportunity). The attacker may not be rational at all; maybe the attacker just wants to create chaos, even at great expense. Like I said, incentive structures are unreliable and make for a poor approach to security on the Internet.
