Different environment here. A partial rollout can be deadly as well. Its worse than asking Boeing to do a "partial" rollout of aviation software.

But its much more than just software - its hardware and different kinds of hardware as well.

Its also multiple different railroading companies from all across the country, with 1000s of locomotives. For example, a UP locomotive may be attached to a cross-continental train in Oakland and end up on the NEC 8 days later.

That UP locomotive would need to have the PTC hardware and software installed.

Using foreign power happens all the time. When a train crosses from one railroad to another, at most a new crew comes on but the locomotive stays with the train.

That new crew needs to know how to run the locomotive, there can't be wildly varying versions of PTC equipment onboard.

Now throw in all the leasing companies that have equipment of varying ages and abilities to be retrofitted.

And if life isn't complex enough, the NEC has 3 different electrification systems and a few short line railroads.

Railroading has a heavy, hard-fought focus on safety. Before railroad companies got really serious about safety - railroading used to be quite dangerous. They are not going to just "rollout" releases.

And to your statement about "not all of the issues need to be solved". Actually, yes they do because having trains just down or be slower than needed because of PTC is not reasonable either.

Consider this, a well functioning railroad has an average car velocity of about 25 mph. A railroad that is snarled with locomotives badly positioned, crews going outlaw in the wrong place has a car velocity of 21 mph or so.

Now you are going to throw in some half solution. Not. going. to. happen.
S3 will normally provide ample bandwidth, but in some situations there's a local shared downlink that is the bottleneck. For example in asset heavy multiuser VR or game apps used by many people in same location. By only including the nearby peers I get all the benefit but minimize the risk of people accusing me of clogging / mooching off their uplink.

SPJ and J Launchbury seem to think ST is pure.

Looking over the PLDI paper, I get the impression that the key difference between ST and the usual State monad is (1) the ability to name state, and (2) the use of parametric polymorphism to prevent scope-extrusion of state.

Of course ML has scope-extrusion of state, and one of my questions/examples upthread was about the ability of Haskell's monadically controlled effects to implement such scope extrusion without 'tricks'.

All in all I feel that the notion of purity is controversial, insufficiently theorised, and that the community would benefit from a clearer understanding of the trade-offs involved in the different notions of purity

Some would, but there are plenty who prefer the obscurity. Most aristocrats are more interested in impressing their friends and immediate circle with off-beat style than in starting a popular museum or being seen as gaudy. Obscurity is hip--and sometimes it can even be affordable.

For me, cash payments mean privacy (at least until all shops have facebook-uplinked facial recognition cameras installed in every corner).

But then again, Danes never seemed to care much about privacy (you can look up a person's address and all kinds of personal data if you know their social security number, for example), so I doubt there's going to be much backlash.

Being able to see every time a dollar (or krone, I suppose) changed hands isn't enough for the taxman though. Last month Tarsnap Backup Inc. wrote me a cheque, and there's a very clear electronic trail showing the money moving from Tarsnap's account to mine. But that electronic trail says nothing about the reason why the money moved.

If Tarsnap was paying me a bonus, that would be taxable income. But if Tarsnap was merely reimbursing me for expenses I paid on my personal credit card, that's not taxable. The taxman can only tell the difference when they turn up at my door and ask to see my records showing why that money was paid.

(The answer, incidentally, is that Tarsnap was reimbursing me for the AWS bill I paid via my credit card. Tarsnap, being a Canadian small business, can't get a US dollar credit card with a limit high enough to pay its AWS bills, but my personal credit card has a generous limit.)

The main problem is that we're way too productive for the amount of people we have. The best solution in my mind is cut the average job back from 8 hours to 4-6 hours, and have some very strict rules about overtime. You basically have to make it so its worth it for the larger companies to hire more people rather than squeeze what they can out of their exisiting workforce.

Just like shops in Canadian border towns which accept US dollars (and vice versa), I imagine the shops frequented by visitors will either continue to accept cash -- or, if 20 years from now it's phased out entirely, accept Euros (at a discounted rate, of course).

> When and how will it end?

The situation is caused by the government attempting to control lending cost. This has happened before and it will happen again. Essentially governments are currently attempting to create a massive wealth transfer from, well mostly everybody, to their favored causes (firstly to government spending, and second to property values, through banks). To do this they are taking out what effectively are huge loans.

So central banks are painting themselves into a corner. They are making it extremely easy for the government to borrow. Why ? Because this will make it easy for those governments to pay off the debt burden that has become too much for them. Of course governments aren't paying off debts at all, rather they are increasing spending (look past the austerity rhetoric to the actual numbers : taking into account that their debt servicing cost is decreasing by a LOT, they're actually increasing spending by over 10%, all of them).

This makes those debt burdens a lot worse, because that cheap borrowing cost is temporary. Debt that is serviceable at 0.2% interest costs double as much in debt service at 0.4%, which is a tiny change.

So the situation becomes more and more unstable. This could last a few years though.

So what will happen next. Most/all of the governments in Europe (and the US) will likely end up in the position Greece was in 2 years ago, or worse, due to a tiny rise in interest rates. Then they will default on at least some debt. This will cause an enormous spike in interest rates, so it will become prohibitively expensive for governments to loan money at all, and they will lose the ability to rollover debt. So they either come up with 100% of GDP without loaning money (ie. massive inflation), or they default on more debt. This will crash banks (but don't worry : government guarantees have been gutted so it won't cost the government anything. Google "bail-in legislation").

At this point interest rates will shoot up to 10%, maybe 20%. All those investment properties in Londen will suddenly be extremely costly to their investors (their monthly payments will double or triple in a year), and go on the market (the problem is not too little housing, the problem is that for the moment it's too valuable to invest in real estate, given the rising prices).

And then we're back in 1992 or so.

> buckling themselves in with the student debt and the mortgage to spend their entire adult life under the heel of the capitalists.

Sadly, you can be assured of one thing : when this story has played out, you'll be worse off than today, for at least a few years. And God help those with student debt, or even worse : those with student debt backed by a state (US, UK, Australia, Netherlands all have large amounts of people with lots of student debt backed by the state).

(You probably want Arvid's libtorrent, at http://www.libtorrent.org, not the one linked above.)
There is nothing that says that cash-free also implies that all payments are transferred via credit card companies and banks that record everything. A cheaper system for small payments via some form of "electronic cash" needs to be added to the mix. If we are in luck, that system is invented by someone other than a credit card system, bank, or Apple.
I wouldn't call them statements because they aren't executed. Instead, I would classify them as "declarations". You state what something is, instead of telling the computer what to do.

Traditional assignment is an expression in Haskell.

| otherwise = do v <- readIORef r

I guess he's using a different meaning of 'dinky' to the one I'm used to. The dictionary says that there's a US meaning of dinky meaning 'inconsequential' which seems to make sense.

Many chiropractors in Scandinavia are basically physiotherapists specialized in back/neck problems, so the normal criticism about chiropractors doesn't necessarily apply to them.

It is a taxman dream, of course. But I would not be surprised if it was seen as largely positive by most citizens, especially the honest ones (and most citizens are honest by virtue of being salaried, with little to no room for fraud).

It depends on the country of course, but tax fraud (or even tax evasion) is rarely seen as a good thing.
"The difference to other jurisdictions is however that negative interest rates have become so pronounced, that it is by now worth it to simply withdraw one’s cash and put it into an insured vault."

Wow, this is an awesome read. I especially like how each algorithm starts with a simple explanation and then dives deeper into each lesser known vocabulary.
A few days ago there was an article [1] posted here [2] about negative interest rates:-

As long as paper money is available as an alternative for
customers who want to withdraw their deposits, there’s a
limit to how low central banks can push rates. At some
point it becomes cost-effective to rent a warehouse for
your billions in cash and hire armed guards to protect
it.
[...]
Bank notes, as an alternate storehouse of value, are a
constraint on central banks’ power. “We view this
constraint as undesirable,” Citigroup Global Chief
Economist Willem Buiter and a colleague, economist
Ebrahim Rahbari, wrote in an April 8 research piece. They
laid out three ways that central banks could foil cash
hoarders: One, abolish paper money. Two, tax paper money.
Three, sever the link between paper money and central
bank reserves.

Of course, inflation already serves as a tax on savings, so this isn't as radical as it sounds if governments really want to discourage saving.

How do you give money to a poor homeless person?
Contrasted with the extremist dream of the cash only society, where there is so much corruption and bureaucracy (as a defense method against corruption) that society can't properly function (see Iraq).

I personally think a mix of both is good. I'm a supporter of receiving electronic payments from work, with the ability to spend it as paper if I'd want to.
I used to have my own, self-hosted at home on the same computer I used for everything else. It was about learning mostly, I was like 19 years old and had plenty of time on my hands.

If I were to do it now it'll be just to keep my archived mail out of someone else's servers. However, I do trust my current email provider. At the moment I feel like I get much more benefit short and long term by using these people's mail service.
I can't see how it's such a big difference from today? There is no way I could get my salary in cash/cheque, the only way I have of accessing my own money is via the bank it is transferred to.

99% of the time, I access it via a debit card at a. Granted, when I get cash I can buy something that can't be traced, but the cash man doesn't really care much what I buy, the VAT is taken from the store. If I was suspected of terrorism or some other crime that meant my assets should be frozen, that is a single push of a button already. I don't have a safe with cash, most people don't. Even if I had, it would be exceedingly hard to live cash-only, as any major purchase done in cash would be affected by money-laundry rules, so the tax man would certainly be informed if I bought e.g. a car cash (If I did so from a dealer I wouldn't be able to do it anonymously).

The taxman would ask you to file that explanation; 4 years down the line, 5 times, to different auditors, at different times, using different forms. You are presumed guilty until you've proved your innocence. And if you've lost the paper trail - well, then, it's a taxable bonus.

7 Reasons Why Your Company Is Not Growing?
An OSGI first software artifact repository
I'm currently using this to build a decentralized distribution system to ship relatively big database files to iOS clients without having to go through S3 all the time. It works quite well but some providers throttle the bittorrent traffic (or worse, throw in RST packets) so I'm not sure how well this will work in practice. Also note that the S3 default seeders only upload at around 80kb/s, so you'll always need at least one external seed to get good performance.
The rise of electronic payment could also raise privacy concerns, but Hahn said these pale in comparison to what it would mean for state revenues.

Those two things appear related but they really aren't. The claim that you need a detailed record of all transactions in order to maximise tax revenue and stop crime is wrong; you only need a record of the financial aspect - the value of the transaction, when it happened, what was purchased, and what tax was due. You don't need any information about who bought the items to ensure the tax is collected properly. You could have a cashless society that respects privacy by making a legal requirement for the details of who made a transaction to be stored separately and anonymously to the tax reporting information. If Denmark's system doesn't do that then they have made a choice to deliberately limit people's privacy. Suggesting privacy has to be compromised in order to report tax receipts properly is nonsense.
