  1. Actually fiat currencies also have a problem with underlying value. They are no more than a promise by the state. If that goes wrong, as it has done quite a few times, then you end up with hyperinflation. I'm not opposed to crypto currencies in principle. They may turn out to be a good thing, or at least some of them might be. I don't think that Bitcoin will be one of the ones that survives, for the reasons I stated in my last post.
  2. Another major problem in using Bitcoin is that its use doesn't scale very well. The blockchain is only updated every 10 minutes which makes it pretty useless for a lot of day to day transactions. There's also the worry that you can spend the same bitcoin twice within that 10 minutes and only one recipient will get paid. Recently on the Tube (London Underground railways) I've seen advertisments for cryto currency trading. There are strong warnings in small print about it being high risk etc. If it's being advertised like that it feels like something nasty will happen. No doubt a few will win handsomely. Most will lose. The blockchain may well be a very good basis for a currency. It also has application to conventional banking. But I doubt that Bitcoin, with its energy hungry mining and lack of scalability, will become the main crypto currency of the future.
  3. When a quantum computer (or an advance in number theory) allows large products of primes to be factorised in a practical time then the whole of internet security comes crashing down. Every time you go to a https webpage there's an RSA key exchange using the properties of large prime numbers. Crack that and there's no such thing as a secure online transaction.
  4. Skirts!

    Very few women (or men) could wear this outfit well in an everyday environment. It's very much for the right sort of club or special occasion.
  5. Not strictly infinite, though solar (PV and/or thermal) resource is potentially so large as to make it seem so. The market will indeed determine the future of bitcoin and other cryto currencies. 20:20 hindsight is a wonderful tool for assessing the past. If you had invested in bitcoin a little while ago you would have won handsomely. However it is pretty useless for forecasting the future. If you buy bitcoin now it's not a guaranteed win, it's an outright bet with utterly unknown and unknowable odds. I'm not sure if bitcoin amounts to a zero sum game. In other words if I win £1000 then others elsewhere must lose £1000.
  6. Whether you pro or anti bitcoin, one thing cannot be denied: they are an ecological horror story. The energy cost of mining bitcoin is high. https://spectrum.ieee.org/energy/policy/the-ridiculous-amount-of-energy-it-takes-to-run-bitcoin There are possible fixes for this but the energy cost of mining needs to come down for bitcoin to play a major role as a currency. I think that Etherium has fixed this problem so it might be that in the medium term bitcoin will be an "also ran" in crypto currencies. Much as bebo and others lost to facebook and many early online retailers lost out to Amazon. Fiat currencies have energy costs too. In minting coins, printing notes, distributing credit cards etc but I think these are relatively small compared to face value. Though when the scrap value of pennies (US or UK) became higher than the face value the composition was changed from bronze to plated steel.
  7. Posting

    I use Irfanview for all simple picture editing. It's free, quick and easy to use. http://www.irfanview.com/ If I simply want to reduce the size of a picture file there are plenty of "right click" tools for Windows. Example: https://www.digitalred.com/support/windows/image-resizing/ When editing images don't confuse the number of pixels with file size. You can have a lot of pixels but small files if you use a lot of JPEG compression. This usually gives better quality than reducing the number of pixels and using less JPEG compression. I don't know about equivalent tools for Linux and Mac.
  8. That's the nature of innovation. Some win, the majority lose. Who wanted Edison and Swan's crude electric light bulbs when we had perfectly good gas lighting? c1900 it wasn't obvious that the internal combustion engine would dominate for over 100 years as both steam and electric vehicles were successful back then. Amazon shook up the retail world and succeeded. Plenty of others failed in the dotcom boom/bust. Sometimes even titans lose. Let's add Nokia to Kodak. Who knows if Apple will be a "has been" company in 2037. When we look back from 2037 I have no idea whether Bitcoin and its ilk will survive. The blockchain concept will probably endure but perhaps in ways we can barely envisage now. When Vint Cerf invented TCP/IP could he, in his wildest dreams, have predicted the WWW and its huge growth? The roots of hyperlinking are many and varied. Including Vannevar Bush's ideas in the 1940s. Took the genius of one man to invent the WWW, originally to solve a problem of sharing information at CERN. In 1993 I doubt if even Sir Tim Berners-Lee could have envisaged what his invention would do in less than 10 years. Innovation is a crazy business. Some ideas make it big time, most fail. Some get resurrected, electric cars for example. Most are forgotten except by specialist historians.
  9. Latex socks

    From what I've heard about wearing latex socks (never done it so this is secondhand) is that they fill up with sweat and can get very unpleasant. They also wear through very quickly. While latex clothing is now worn in public by loads of celebs it still has a strong aura of fetish about it.
  10. Latex socks

    I don't see the point of ultra short latex socks. If you really want them why not just get some longer ones and cut them down. HHP isn't meant to be a fetish forum so this might be better asked in the relevant part of Fetlife. I won't link from here as it wouldn't be appropiate but from looking at your posts I think it's likely you're a FL member already.
  11. Very high heel clogs

    I'm not claiming this is a lovely shoe but Sanita are a major maker of clogs both for the workplace and leisure. This has a strap: http://www.sanita.com/Sanita-Stride/ I wear Sanita clogs much of the time, usually these: http://www.sanita.com/mens-karl-pu-black/ Can even just about claim they have a heel as it's about 2" from the back of my foot to the ground.
  12. Megan, I think you've rather limited the functions of money here. Yes, it can be a token of wealth but another function is a means of exchange and keeping track of transactions. Every time we buy something we're using money (as cash, card, tally stick, bitcoin etc) as a means of exchange and effecting a transaction. It's more convenient than bartering my good for yours. You can see this in a simplified form in local currencies (LETS). When I referred to commodity money I was using the generally accepted definition of using something of instrinsic worth to represent money. Such as gold, silver etc. Anything that is widely accepted as being of instrinsic worth can be used as commodity money. Whether it be gold, conch shells or whatever. Treating money as a commodity is a whole different question. It has a physical existence of some kind, whether it be gold, dollar bills, a mark on a tally stick or some electrons in a particular place on a silicon chip. Or more generally it can also exist as information (the distinction between bits and atoms) which can be transmitted and received. Problems arise when money becomes the object of the exercise rather than it being a means to an end. The love of money may not be the root of ALL evil but it accounts for a fair amount. The problems get even bigger when people start trading in debts, derivatives and more complex financial instruments. Many of these things have legitimate uses (I no longer wish to lend money to Mr X to buy his house so I sell the debt to Mrs Y, possibly at a discount, and can then go out and buy an expensive holiday) but taken too far it ends up as the 2008 crash.
  13. Very high heel clogs

    Thanks. That's more extreme than what I saw and has open toes. What I saw had closed toes, they were impressively high but very much not fetish. Link to Pierre's shoes: http://extremehighheels.net/en/extreme-high-heels-boots-and-shoes/111-high-heel-chunky-heel-clogs-italia-p.html
  14. Hands up those who bought an Apple Newton? Definitely not me. I was probably in the early majority to get online (1995/6) and late majority for a smartphone (2013) and still use that same 4 year old phone as I've not yet found a good reason to replace it. As with a fair bit of social science research, Rogers makes a rather big deal of a subject that's intuitively obvious. Though perhaps it wasn't so obvious back in 1962 when he did his original work. Not sure he covers how scarcity and cost can slow down adoption. I can remember when just getting a landline phone installed in the UK could be expensive and often involve waiting for the GPO to pull its finger out. As for economics, I'm sure there's some value in it but I struggle to find it. Just remember that if you place 1000 economists end to end it's doubtful if they would reach a conclusion. It's not known as "the dismal science" for nothing.
  15. Very high heel clogs

    Definitely higher than the Miumiu clogs linked by Charlotte. I can't see any clogs on the extremehighheels website but perhaps I'm not looking hard enough. Pierre, can you please link to the model you have ordered? If clogs fit well they can be easy to walk in despite the heel height and lack of strap. Even without a strap your weight keeps you in them and stops them slipping off. Until you walk backwards when it's all too easy to walk out of them. The woman I saw looked entirely at ease in hers.
