See, I remember the huge growth in merchant adoption in 2013 for Bitcoin and how for a moment in time Bitcoin was useful as a currency. I actually used Bitcoin back then from my 2011 minings.

Now I agree that there is a niche for Monero in black markets.

Then there should be a huge opportunity for some crypto currency to take over Bitcoin in the role as a medium of exchange for general public.

Thus it really irks me that I am not seeing these supposedly revolutionary crypto currencies attempt to do anything useful.

Why doesn't any cryptocurrency focus on usability for a regular audience first?
Programming Rust has 21 chapters and is 583 pages long. I’ve read it, and I’ve also read the online Rust Book (both several times). Most chapters are in the order of 20 to 30 pages long. Programming Rust is one of the best programming books I’ve ever read, and I’ve been coding professionally since 1997. If you want to get an A+ in Rust read Programming Rust a few times. You can see the entire Contents section of the book on Amazon. Below is a list of chapter titles from Programming Rust that get little to zero coverage in this Learning Rust website.

Ownership. References. Expressions. Error Handling. Enums & Patterns. Operator Overloading. Closures. Iterators. Collections. Strings & Text. Input & Output. Concurrency. Macros. Unsafe Code/FFI - the coolest part, they show you how to create a safe wrapper around libgit2.
One of the articles that came out apparently around the time of the publishing of "The Myth of the Paperless Office". I recall reading one or more of the articles, back then, and finding sense in them. I never read the book; if I learned of it, back then, I'd forgotten about it.

I don't know whether this is the best of the articles. I seem to recall a longer one. And, this one comes with a "Gladwell" (the author of the article) caution.

Not sure blockchain is what you are looking for, but TOR might be.
Another problem with governments is that they're made up of dozens or hundreds of different organisations, and they all make these mistakes on their own. Even if one organisation gets it right, other parts of the government don't benefit from that expertise.

I think governments should have a special organisation that just maintains the expertise for handling these sort of big projects all across the government.
I doubt you can compare that to the NSA, but sure.
One of The Onion's best skits is a about a very "Kafkaesque" business.

I had immediately thought of the Apache Kafka project, but this makes much more sense.
Thanks for the new reading material too :)
Well, since you're here...

In mid-November, I bought a Christmas gift for my son (a drone) on-line through Wal-mart.

The text on the Wal-mart web-page urged me to purchase now (to guarantee on-time delivery).

The shipment of the drone was fulfilled by a 3rd party.

I got the drone in early December, wrapped it and my son opened it on Xmas day.

Drone didn't work. Out. of. the. box.

I asked for a refund, and Wal-mart customer service told me to pound sand b/c the product came from a 3rd party that had a 30-day return policy (no exceptions).

I know I'm a drop in the bucket, and I may not always be able to avoid Wal-mart, but I told them I would do my level best to shop elsewhere.
I'm guessing you want more specific guarantees than databases attempt to provide. Like losing only last couple of commits in case HDD or an OS lies about writes, but not corrupting the rest of the database. If this is right, than sure it is possible to do better with something purely log structured with checkpoints. But this is not what SQLite and such databases aim for, they assume you achieve those things with backups.
All I'm saying is that for a certain set of potential customers, this tips the balance from spending money to not spending money. A handful of people inside Intel and computer OEMs are probably spitting feathers about this circumstance. At the present time, I feel no pressure to accept anything.
Walmart is one of the largest ecommerce businesses in the world...
This is the answer for so much in technology.
lol, with lightning you have to rely on a small number of centralized payment hubs who will likely be strongarmed by the government into keeping tabs on transactions through KYC/AML laws.

It completely breaks the fundamental and original usecase of bitcoin: peer to peer electronic cash.

Now it's "first world speculator to first world speculator through intermediary financial institution electronic store-of-value". Doesn't roll of the tongue quite so well, does it?

IMO, XMR and BCH are the current best options for transactions. BTC is being destroyed by people who hadn't even heard of it 5 years ago.

Yeah, even simple things like "See Figure 4" can become a big hassle in ebooks. (Is that on the next page? The page after?) And what you really want to do is re-read the text and then quickly look back at the figure -- which is just always going to be much easier when you're flipping back and forth between two pages that you're holding with your fingers.

Maps is the other big thing. Reading a book about the Lewis and Clark expedition (or the Astoria fur-trading party), there's always one big map showing the entire route of the expedition, and you'll want to refer back to it several chapters later. Yes, you can still try to bookmark it in an ebook -- but accessing it is something like "Menu / My Bookmarks and Notes / Page forward, page forward, page forward, page forward...."
... and values your time next to nil.
This doesn't surprise me at all. The last time I was actually in a Wal Mart I had an employee yell right at me when I asked to get by their carts in the way. I complained to their corporate, expecting at least a call back. I got nothing. No phone call, no emails, nothing. They really do not care apparently. So I refuse to spend any $ there ever again.

Sam Walton once said "There is only one boss. The customer. And he can fire everybody in the company from the chairman on down, simply by spending his money somewhere else"

But does anyone really think that they still follow this advice? Wal Mart has a well deserved terrible reputation.
That is true. I guess my definition is as long as new players / players with different motives and agendas can join the fray, it is ok.

So like I don't mind if we end up that you need at least $1million to become a miner, hell we are half way there anyway on both chains, I just mind if nobody can join, or if it goes to $1billion to be able to mine.

LN seems like the ultimate in centralisation so as an alternative (while it might work,) it's a far inferior solution on that score.
If anyone is really interested in this sort of thing, I suggest you take a look at SaferCPlusPlus[1]. It is "A Usable C++ Dialect That Is Safe Against Memory Corruption" (including data races). And it already exists.

And I think it's better than this proposed dialect in that most of the (safety) restrictions are enforced without requiring extra tooling, and it's much less restrictive. Most existing C++ code can be converted directly. And the run-time overhead is kept to a minimum. Btw these advantages apply versus the Core Guidelines[2] as well.

Clearly, the real problem here is Russia typosquatting all our location codes.
I think the idea is that due to the existence of LN, you would almost never need to settle on-chain. But because you theoretically could, you maintain all the benefits of genuine financial sovereignty without ever having to actually exercise it.

I don't believe so: if that computer is reading a bunch of serial lines forgets to check the bounds of it's own buffer - then Houston's got a problem. That's all it takes.

At least we've got a set of verified, battle-tested, multi-platform TCP/IP stacks. More importantly, they have been built with generalisation in mind, meaning that a single implementation would encapsulate all of the use-cases.

But instead we've got those half-baked implementations of "oh my god, it takes me only a few hours to establish a radio link" protocols just increasing the attack surface.

You're speaking of a semi-technical solution to a problem that is directly caused by the race to the bottom in the manufacturing industry (they probably have installed that equipment a few decades ago, just before they fired the last of the employees).
Right, because they're a VPN.

This isn't just how to do stuff for 0$, many of those companies seem to deliver great products to grow in! :)
Exactly. Costs for computing/disk storage go down exponentially.

Cryptocurrency tx/sec goes up exponentially.

As long as the two rates roughly cancel out, we're okay. If they're massively different rates, then you're still dealing with an exponential which is difficult. Either way though, lightning is a linear benefit, not an exponential one. And it comes at the cost of breaking everything that made bitcoin great in the first place.

I don't ever want to have to deal with an intermediary financial institution again. Somehow, the pro-BTC side of the chain thinks that view is ridiculous.

Governments used to build things in house as well ... I remember the first time I applied for federal student aid — in 1999 — it was a long complicated form but it was far more complex and functional than any web application I’d interacted with up to that date.

Built on in-house knowledge rather than subcontracted out to incompetents with zero stake in product quality or understanding of what they were trying to build ... (aka the outsource everything mentality of the gop that spread everywhere during bush era from which American government managed infrastructure on all levels has never recovered — and probably will never recover)
You could ask the same people who host PIA servers to host your RPi, given that PIA don’t run their own network.

PIA state they don’t keep logs on their servers, they can’t provide those guarantees on the network as they don’t run the networks they operate on.

Plus colo and transit costs more than paying for a slice of resource someone else is already hosting, so there goes that price model.

And even developers are paid badly when compared to our peers in the states and with other professions in the UK.

You do know that the train driver on my commute to London is paid £60k for a 4 day week and most of them after overtime are on >£75k with a DB pension!

The UK has been known for decades as a place to get good engineers cheap.
False analogy. In terms of throughput the analogy is good, but you neglected that lightning breaks how bitcoin works. You need to get permission from a centralized lightning hub to transact.

Also, high fees (which blockstream vocally is in favor of) increase UTXO bloat by preventing consolidation

Can anyone explain what's so complex about a "payroll system"?

Presumably you just have a table with people with salary, and every month you wire the money and record information about the wire or otherwise have a way to record when the person has taken cash.

You might want to have more complex rules for determining schedule and amount of salaries, and support for contractors, unpaid leave, taxes, etc. but that doesn't seem particulary complex either.

How can this possibly take more than 100 person-years (i.e. < $30 million) to make even a truly extravagant version of?

Not to mention that presumably such software already exists and could be used instead of writing a new one.

Is it common for pedestrian bridges to be so overbuilt? Given the weight and span it sounds like it has a cross sectional area of about 75 square feet of concrete (a little less for the steel components, but still a lot) for a mere 15 foot traffic deck. It's not crossing an especially large span nor need to carry any substantial weight other than its own, so why does it need to be so heavy?

Are they expecting trucks to run into it maybe?
Ultimately Amazon will eat them if they don't compete on customer service. Amazon is still being run by their Sam Walton, with Bezos obviously being obsessive about trying to make customers happy (although I wonder more recently if he isn't likely to lose focus, spreading himself & Amazon way too thin). That's of course why even huge companies tend to die and or fade given time, it's nearly impossible to maintain the founder fanaticism that got the business to the top of the mountain in the first place.
Sure, the reasoning is clear, we're in a "fraud first" world. Still yet, if there was some sandboxed setup I could use, I'd happily do that. And if it works, I'd happily hand in (my employer's...) billing info thereafter.
To be fair, lots of founders say this to press, and tell a completely different story to investors. I don't know anything about Howie Liu but in general there's roughly zero correlation between what a founder tells reporters about acquisition plans and reality.
The current de facto status is that the concept of species does not exist anymore, or more precisely, it mostly only still exists for historical reasons and coherence with it. When talking about genetic identity nowadays there is only the (type) specimen and genetic distance to other individuals. For example, Svante Pääbo and his team set precedence on purpose in not declaring the Denisovans anything but only describing a group of humans that genetically differ to an unexpected degree from modern humans.
Exactly. That was a bridge too far!

They show whatever they want to show. For example see https://www.google.com/search?q=matemathica If you search for "matemathica" they will show the results of "mathematica" instead, and offer to search for the original word. Sometimes they mix the results of the original word and the autocorrected version. Sometimes they show the results of the original and offer to show the results of the autocorrection.

We have all seen a project go wonky with requirements. However, I haven't heard of a successful product that IBM built/managed in the last decade.

On the other hand, talking with friends in the government and government contracting, they argue that IBM and the major contractors have perfected the art of exploiting government into maximizing billable hours at the expense of results.

Yeah that’s a good question. Reading between the lines of that article, I’d guess they’re worried about the damage caused by people taking regular folks money, which would surely exclude blockchain consultancies. That’s based on a giant assumption that their filtering can spot the difference effectively.
An answer to you and to most of the other comments in this thread:

This isn't what I was getting at. Take for example university students. Their earning power is significantly smaller than more experienced people. They also tend to need a lot less money, because they're usually single, don't often have a mortgage, live in a small apartment or in their parent's house, etc.

Many students work part-time in a restaurant or similar. For them, this will probably be a "livable wage", whether because their needs are smaller as discussed, or because they're relying to some extent on their parents.

Take another person of the same age, but who has a family and no parents for support, and assume they earn the same. For them, this same wage is not livable.

How would you statistically separate these cases? I'm not saying there isn't a way, I'm just wondering what it is!

Their online growth rate went down so much in the most recent quarter, because they rolled year over year past the acqisition of Jet.com. It's an issue of YoY comparables.

Remembering and tracking all the agreements made with workers and unions going back decades and handling the cases where workers change jobs and union designations (or even move from one union to another).

There are thousands of byzantine rules in the contracts and agreements, some mutually contradictory.

The old code likely contained a lot of business logic that represented an institutional memory of how to handle all these corner cases.

Anyone wishing to reimplement a system like that will have to rediscover these corner cases one at a time in production, while thousands of people complain that their paycheque is short.
