vrotaru··on Bitcoin exchange rate reached $100 USD per BTC
Yes, that is it. Contrary to the popular belief, just holding money under fixed supply monetary regime doesn't make you rich.

A Rip van Winkle with a year savings (say clerks' job) falling asleep for a 100 years will not wake up a Rockefeller.

You totally wrong, and the reason you are wrong, is because you do not understand growth. Like... totally.

Yes, I'm arrogant and I'll deal with an idealized model where the same set of resources is transformed into final goods, but bear with me.

In order to get a real growth of 4% be it per year or per century in such a scenario, you need to find a better use of resources so that with the same resources you may produce an output which is 4% greater than before.

Which is the same as saying the the only way to grow is to find ways to produce final goods cheaper.

And because production is cheaper, more goods could be sold but.. entrepreneurs will still make a profit. Pretty much the same.

And the fact that final goods get cheaper means just that.. That goods get cheaper.

And you will not get rich by just holding bitcoins, or any other fixed supply money. Yes, you will be able to get more stuff for but only because the stuff get cheaper..

You'll still hold the same fraction of total purchasing power that as the day you decided to "hoard" your money for a while.

That's not what I call getting rich, and that's why loans and interest make sense and are safe with bitcoin.

P.S. Take you time. It's late in my TZ.

vrotaru··on Bitcoin rises
Gresham law works only when the exchange between the good/bad money is fixed. Usually by a government/sovereign decree.

Otherwise quite the opposite is observed in real world. There's even a word for it. Dollarization.

vrotaru··on The Target Value for Bitcoin is $100K to $1M
I remember some commenter saying on Scott Sumner blog, with reference to the discussion whether bitcoin is in bubble or not.

  *The price of bitcoin is volatile, because the future of bitcoin is volatile*
Yes in one of this futures where Bitcoin is The Money having a whole bitcoin will be a big deal, in which case it will make no sense to speak of the price of bitcoin in dollars.

I can think also of a transition period when bitcoin will widely acceptd and function in parallel with the dollar. For such a future the price range seems about right

I seem to remember that specific Swing L&F (look & feel) is at least partially generated code using an in-house tool.

It also implements a specific interface Painter<JComponent> which explains the Why and the javadoc is copied from its parent class.

So it is not as much an example of beauraucracy as of code-generation.

I will exclude France and Germany if the (Shift-123) is different from French/German layout, but otherwise a lot of programmers (power users) use the US layout. Esp. if we are speaking about people of certain age who maybe have started when DOS was cool.
vrotaru··on Another go at the Next Big Language
_For good error reports back to the user, you'd have to have a fairly large amount of logic in the catch block._

Serious question. How is that a reason to have that _amount of logic_ in the function body?

Having IDE/editors which can fold blocks of code and having the catch blocks collapsed by default will make code reading/understanding of code easier. IMO.

Actually, I may try something like makng the try-cacth the body of the function on a small to medium size project just to see the tradeoffs.

vrotaru··on Another go at the Next Big Language
I remember reading a paper proposing error handling to be done only at function not block boundaries. A minimal change from the normal exceptions will be something like this:

    function foo(bar, quux, zut) try {
        var a = frobincate(bar, quux);
        return bubinate(a, zut);
    } catch (e) {
        // Stuff        
    } finally {
        // Stuff
    }
Whether such a change will make code easier to write, read and maintain is hard to say. Writing a language that compiles to JavaScript and uses that syntax shouldn't be that hard. I'm partly tempted, but I almost never program in JS

If those are reasy HP and partners can sell them at a premium.

Vuze (former Azureus) has quite large base install. There alose should be quite a lot of Swing in-house apps.

It would be quite intresting to watch later the statistics of access

vrotaru··on Joe Armstrong: Why OO Sucks
Umm... Pseudo-code follows

     module Book = struct 
         type t = { sections: Section.t list; ... }
         ....
         get_paragraphs t = map (fun s -> Section.get_paragraphs s) t.sections  
         .....
     end
So it is not that hard to have both FP and DL

Sure. But the proposed measures still must make sense. For those willing to risk their money first and foremost. Otherwise those (with the money) will just shrug

vrotaru··on Europe's Wile E. Coyote Moment
I agree with a lot of what you said above. I just don't think it changes the general picture that much.

> Please explain under which conditions the US government would become unable to fulfill the promises implied by its debt.

At the point where the choice would be a) currency destruction (10-15% inflation), b) default.

> and is completely risk free because the US government is monetarily sovereign.

So what? Ctrl+P is cheap, but that's besides the point. The reason USA is not Ctrl+P-iing now, but is borrowing instead should at least serve as a hint.

My point: If it is OK to Ctrl+P at later date as the Is-Safe-To-Borrow propaganda wants us to believe why is not safe to Ctrl+P now? Why borrow when you can print?

So, no. No such thing as free cookies or risk-free debt. At least this side of the Jupiter orbit.

Yes, it would be a different endgame, as the one for Greece, but this is not the same as risk-free.

vrotaru··on Internet-induced fear culture (or: Why Girls Around Me isn’t the problem)
Well, no. The original article was more like a book about the danger of books.

This one is like a book about mostly-hamrlessness of books and more.

vrotaru··on Bitcoin may be susceptible to Goldfinger-style attacks
What I like about bitcoin, even if it only a side benefit, is that make people think about things that most of the time are taken as granted.

That the conclusion is flawed, as it is in this case, is not that relevant.

PROOF: Suppose you have garnered half of all the bitcoin in existence. An absurd supposition, but it is only to make a point.

Now you have half of the purchasing power of the bitcoin economy, the other half being hold by other people. Now if destroy half of your coins you (surprise, surprise) you only hold ⅓ of the all bitcoins. So you have succesfully reduced you purchasing power. Congratulations.

vrotaru··on Scala Macros: “Oh God Why?”
I seems to be a rather common tension in open source projects developed by research institutions.

The goal of users of those projects is immediate usability which clashes with goals of developers, research.

I have some doubts where one can get PHD (publish an article with high citation index) by improving a compiler error messages. As opposed to adding a new cool feature to the language/compiler, cryptic error messages be damned.

Quite. For whatever reason I was under the impression that the demanded information was on Google servers.

Who cares whether the password is hashed or not. All other data related to X is not.

   select * from smses where login = ?
So if such a warrant will be issued Google absolutely can deliver.
vrotaru··on Should readers of ebooks be taxed to subsidize stores that sell printed books?
Bastiat would certainly loved such a question.

Even I can invent a lot similar questions, like: _Should married couples be taxed to subsidize night clubs?_

vrotaru··on Compromised Linode, thousands of BitCoins stolen
Not exactly. In order to spend bitcoins (transfer them to other wallets) you need them not encrypted.

So if you are a bitcoin business making bitcoin payments, at moment you cannot avoid the risk of having the wallet stolen if someone gains unauthorized access to your operating computer.

I've got an idea. Spend everything on food stamps. Than rinse & repeat.
vrotaru··on 2^3^4 - a comparison of math packages
Why is exponentiation associative? This:

      4
     3
    2
You should also try to visualize the 4 smaller and 3, and 3 smaller than 2. Because this is the way it was written for a long time.
vrotaru··on Bitcoin's comeback: should Western Union be afraid?
Oh, no. The governments which will borrow more in bitcoin than will be able to pay back, will just default. When Argentina/Russia defaulted on their debts denominated in dollars, how bad was that for the dollar?

So... Bad for them (governments), bad for their foolish creditors but a matter of trifling importance for bitcoin as protocol and store of value.
