I was also a bit surprised by the simplicity of course 1, but then remembered that the course as a whole is designed for folks with no experience. Looking through the descriptions for the other courses (the actual material isn't out yet) I'm hopeful they will have the level of depth I think we're all expecting.
If I were legitimately going to spend a 100 million on bitcoin my first step wouldn’t be to buy 100 million unredeemable tokens from a sketchy exchange with no access to the banking system.
I think it's fine to view taxes that way, but we should also realize that to a business taxes are a cost to be minimized. No for-profit business willingly conducts their affairs to maximize taxes.

We live in a rules based system and the rules should be designed to incentivize the behaviors we want. Expecting any business to deviate from whats in their best interest is just... out of touch with reality.
These are great! I loved 8.02 (actually I took 8.022).

> US (and US only as far as I know) tax laws have a “repatriation tax” that is levied on money coming into the country. This has nothing to do with corporate taxes which are levied on earnings.

I've never heard it described this way before. The tax is only applied if the foreign taxes paid are less than what would have been paid in the US, and the amount of the tax is only the difference between the two.

If a corporation makes X amount of profit in the US, they owe Y amount of tax on it. If they make X amount of profit overseas, then they still owe Y total taxes on it (the sum of the foreign taxes paid, and the US taxes paid). This makes it so that companies can't avoid paying taxes by fancy accounting that pretends that all their profit is in locations that have little-to-no taxes.

The claim that this "repatriation tax" has nothing to do with corporate taxes is just stating the author's political opinion.

Additionally, for talking in such depth about the Apple's foreign cash, the real reason it keeps it's cash overseas is never directly mentioned: because Apple (rightly) thought it would get a tax break if it waited long enough. This completely ignores the circular logic of "we should give apple a tax break" -> "because Apple is keeping its cash overseas", "because it thinks it will receive a tax break".

In fact, there are two ways to make companies like Apple repatriate their cash: Giving them a tax break, or making it clear that they will never get a tax break. One of these strategies makes the rich a lot richer, the other benefits the American public. Guess which one was implemented?
People here are so quick to say confinement = torture. But the keyword here is "indefinite". A weekend isn't torture in my opinion.
Here are some thoughts on how it could work. Not completely thought out, but something:

Before we had electronic bank records, banks could print "bank notes" which were as good as money if you trusted the bank. Now that we have electronic records they basically "create" USD by adding a deposit to your account while only having ~10% of that actually stored away in dollars.

If your account was truly in BTC they obviously couldn't just increase your balance, since it's a cryptocurrency and they can't just make something up.

One option would be for banks to have their own tokens, similar to bank notes of old. All banks would accept the tokens of other banks 1:1 and convert them to BTC on demand, but it would allow expansion of the "money supply" like we have now with dollars.

The servers returned more often in the US than in UK to just check on the table, they returned to get drink orders more often. They brought the check more quickly in the US when we were ready to leave.

As someone who has waited tables as a kid, I know why they did all those things in the US more often. People often tip more on alcohol and you can also get your table turned over more quickly during your shift. In the UK there's no incentive to get more alcohol to tables nor to turn over the table.

I signed up for this course even though after a brief look it looks like more of an entry-level course than a full-blown IT specialist course (which is understanding considering the course delivery being web-based).

I've been writing code for over 15 years and have seen more than enough opportunity to expand my business into the IT side of things, a lot more than contract coding anyway.
I've let these opportunities go by as I don't have any real qualifications although I reckon I could cobble enough together with my experience to get by.

That being said, if I get a cert' from this it might be the confidence to push my business further if nothing else.

I agree completely, the sweet spot is in that 200-500 mile range. Anything longer and I’m not sure why someone would bother unless they really like to take things easy. I’ve always felt that the ideal scenario is just getting trains to average 100mph (forget the 200+mph stuff, you’re not going to sustain that very long). Then it would make it a no-brainer to take a train for those mid-range trips.
VISA does not represent all (or even a significant percentage) or USD energy usage. You have all the banking and security infrastructure, employees, transport, physical manufacture and transport management, computing electricity. There is a lot more going on in the current monetary system than VISA.

Unfortunately it has all the disadvantages of a hold based system. It also has the advantages, but imho those are essentially nonexistent in any practical sense (yes, inunderstand there is a political argument otherwise).

In the hope avoid down voting, in case you don’t know the problem of gold standards are three serious ones. First, it’s deflationary as the gold supply doesn’t change as economic growth occurs. Second, it’s decoupled from economic activity (e.g. you increase the money supply every time you use a credit card and decrease it when you pay off your bill — and that’s only one example). Third, it can suffer inflationary crises (yes, despite being deflationary!) when there’s a big gold strike (as happened with the California, Yukon, and Victorian strikes, among many others).

The argument FOR it is that governments can just print money if they get into trouble and inflate the currency. This usually screws the people doing the inflating as well (see: Venezuela) but can be pretty dreadful (e.g. Weimar). But the problems above are also terrible.
How did you go from 2,079,720,000 KWHrs to 24.07 MW of electricity, 24/7?

My calculator and Google (search for "2079720000 kWh per 24 hours to MW") says it's more than 86,000 MW (so ~86 GW).

localstorage for offline state , if your serviceworker reports the app is offline then any changes of state go into localstorage and are queued for updating when the network is back online.

Any changes to the server side state can be diffed against the localstorage changes and you deal with it according your priorities. i.e is the user always right or does the server take priority?
from the article you linked:

> Of course, VISA runs call centers, offices, and a whole lot else on electricity as well, which isn't counted in this comparison. But those hardly matter due to the extreme difference between the two figures.

---
I think this absolutely needs to be counted, because it is an operating cost of the entity. With bitcoin, there are no call centers because by design, the transactions are irreversable.

When pitted against the total cost of financial institutions, which all independently hold massive amounts of customer data, which should be considered a liability due to the recent issues with consumer data here in the West. This further increases the operating costs of each institution because they are running servers to house account data.

Imagine a global, catastrophic EMI event. Even a temporary one would cause introduce to these systems (like visa), a higher likelihood of race conditions where accounts will not reconcile, causing a higher cost to converge.

Bitcoin does not necessarily have this problem.

If we are truly worried about the future costs of running financial systems, maybe we should also add liabilities into the mix.

These issues are all related to surface land acquisition and management (except piping/cabling relocation). Hopefully tunnel boring won't come up with new unexpected problems; they're far enough from built-up areas that there shouldn't be too much underground infrastructure to work around.

The Democrats are tax and spend and the Republicans are borrow and spend. If you borrow and spend then you need inflation to eat away at the interest you are paying on the money. But you can only borrow so much and quantitatively ease (inflate) so much.
Any online site that sells bitcoins for fiat, like Coinbase, could just keep the fiat (or use it for anything other than obtaining bitcoins) and increment your bitcoin balance. Their total bitcoin holding may be less than the sum of their users’ balances, and no one would notice unlrsss there was a “run” of users attempting to withdraw bitcoins into their own real wallets. We’d probably all consider that blatant fraud.
Averaging 100mph is unrealistic for I-5 most of the time. You'll get stuck behind cars doing 80 in the left lane while semis sit in the right, and that can last for miles and miles. I think things were faster in 2010-11, when the economy was slower, but I only drove it twice then -- even then, 90mph was more realistic.
The joke will be on society after half of this stuff gets refined down to ultimate simplicity (like bicycles), and the other half is refined to a point of "good enough" (like terminals) where no one cares anymore.

I don't think it is. If the > workers DOING THE ACTUAL WORK are able to provide more value than the corporation, then why are they working for the corporation instead of providing more value than the corporation by themselves; and paying themselves more than the corporation pays them? I think OP's argument could be an example of reductio ad absurdum.
Fair point. All I was trying to show was that currencies like the Euro or USD has greater than zero energy usage to create/distribute.

I don't think BTC will stay the top crypto if it cannot resolve its current issues (though new ones will come after). Articles like takes stance, whether they know it or not, of this is here to stay for a long time and we need to deal with the ramifications. If that is true, more people are going to work on solving this issue either, or all of, through energy regulation, better hardware, better renewable energy, mass adoption of different coins, or moving to POS (or anything other proof system) instead of POW.
2:40 minute head time at your departure city? No way.

I typically show up roughly 60-45 minutes prior to flight time, so 15-30 minutes before boarding. By the time I get through security the plane is typically just starting to board and I walk right on.

I have gotten my door to door times between MSP and ORD to just over (sometimes under if I get lucky on train to city) 3 hours including a 20 minute Uber on one end and a 40 minute train ride into the city on the other. Pretty similar distances involved. That's basically 2 hours from dropoff and pickup at the airports for an hour flight.

> going through onerous security

I imagine that in the US, this will be much the same. Or will be the moment after the first attack on a train. I don't see any long-term security gains here, the US is simply not Europe.

Not that I think air travel is a decent replacement for high speed rail though, it's not. The security and time delays related to that I simply think are a long-term red herring within the US. Mostly because I remember air travel prior to 9/11.

I also think comparing a single high speed rail line built in isolation to Europe or Japan isn't all that great of a comparison. In Japan or Europe I arrive in a train terminal and transfer to the local rapid transit that pretty much covers every city and every neighborhood I'd ever want to go to in a reasonable manner. The US... doesn't.

Mind you the USERS don't even want a lot of Steam's competition. The GOG downloader is...okay? Origin is almost universally hated and every time one of these big companies announces $NewNotSteam the collective community rolls their eyes and groans, dreading the new application that has to be installed, and kept running so it can update, to accomplish the exact same thing that Steam, GOG, Origin, and uPlay already accomplish because $NewNotSteam's parent company has an executive somewhere that is tired of giving Valve money and had sufficient pull to change it.
I think the GP meant that it's harder for _the vendor_ to do it, because there are assuredly many privacy-attuned nerds who would run wireshark a bunch on it and notice when the $ListeningPost becomes an always-on bug.

Why not create one big bank that can issue its own tokens that any bank will accept? We can call it a "central bank" or something. And then maybe after many years we can decouple the value of these central tokens from the value of bitcoin, instead allowing the central bank to control the total supply of tokens based on some kind of "monetary policy" to keep prices stable.

Sounds good. The future of crytocurrency is bright indeed!
I was frustrated by the #@ back on Multics and am shocked when it bites me today (usually when globbing).

But to this point:

> There is some debate on whether BS or DEL is the correct character for terminals to send when the user presses the backspace key

These ASCII codes come from teletypes and BS really did just back up a space (I.e. you could over strike) just as LF really did advance the platen one line while not changing the column. DEL really did indicate that the previous character was to be ignored, more useful on paper tapes than printout.

Wow, I haven’t thought about paper tape in years...

You will just hail one for less than the cost of gas.

If the cost of the ride is less than the cost of gas, how is the operator making a profit? Especially since they have to cover more than just the cost of gas.

You're of course right that owners/customers/employees/vendors/etc pay the corporate tax. But when you say "tax the corporations" it sounds an awful lot like "tax the rich people", and people imagine the Monopoly man with a monocle shelling out money from his tuxedo pockets.
