Is It Better To Buy Or Generate Bitcoins?

Total Cost of building PC: $1995.94

How many bitcoins can I buy with $2000? As of this writing it is about $0.066 per bitcoin. So I could buy 30,303 bitcoins if I had $2000 laying around.

Now, how long would it take for my newly designed 25,000 hashes-per-second machine to generate 30,303 bitcoins? Using the bitcoin generation calculator available athttp://www.alloscomp.com/bitcoin/calculator.php, on average it will take 1 day, 19 hours, and 44 minutes to generate 50 bitcoins. After doing a little arithmetic that means it will take a little over two years to generate 30,303 bitcoins!!! Let's not forget to mention that the difficulty levels seems to be rising over time so it could take much longer than that. In addition, the electricity costs to run a server could add up.

That was in August. Now?


For $2000, at current rate, you will get 8000 bitcoins.


To generate 8000 bitcoins, at current rate (50 coins/24 days) it will take 3840 days! Almost 11 years. However, current rate will change, resulting in significantly more time.

Gold taxes

something else to consider: the US Government considers the sale of gold as a "collectible," and the profit realized aka capital gain is levied at 28% instead of current long term cap gains for stock at 15%! Also realize this same higher rate applies to the GLD ETF! so don't think you can circumvent the high tax the government takes via the ETF, instead of selling gold coins. I don't know if the collectibles cap gains tax goes up next year with reversing the Bush tax cuts. However, if buying gold coins, there is sales tax collected from a dealer within your own state, on top of their margin over spot price. There is a lot of headwinds to the liquidity of gold, I think this has lead to greater popularity of the gold ETF, however most people don't realize their realized cap gains are taxed at the higher rate of 28% even for an ETF.

Are you going to go crazy now?

Finally, are you one of those Nobel prizewinners who is going to go crazy now that you've won?

As I've said before, some people stop doing science and just do crazy and awkward things; other people try to prove that they were worth it, and overload with research so much that they go crazy in a different manner; and of course, some Nobel prizewinners are actually senile by the time they get the prize. I'll try to keep my sanity as long as possible.

child abuse

During the 1980s and 1990s, tens of thousands of Americans -- most of them middle-class, 30-something women in big cities, like me -- became convinced that they'd repressed memories of childhood sexual abuse, and then, decades later, recovered those memories in therapy.

In the years leading up to that mass panic, I was working as a feminist journalist, writing exposés of child sexual abuse, trying to convince the world that incest was more than a one-in-a-million occurrence. In the process, I convinced myself that my father had molested me. After five years of incest nightmares and incest workshops and incest therapy, I accused my father, estranging myself and my sons from him for the next eight years.

In the early 1990s the culture flipped, and so did I. Across the country, falsely accused fathers were suing their daughters' incest therapists. Falsely accused molesters were being freed from jail -- and I realized that my accusation was false. I was one of the lucky ones. My father was still alive, and he forgave me.

It's a little embarrassing for a person who's always been thought of as a critical thinker. There's a lot about writing this book and putting it out there that's embarrassing. It's not exactly the most flattering portrait. I think if it were a novel my editor would have rejected it, because the protagonist wasn't sympathetic enough. It really shocked me, I must say, to see how much influence the external had on the internal. That the most intimate emotions and relationships can be so affected by the dominant paradigm.

internet privacy

I can't follow you outside slashdot unless YOU make that possible. I don't know who you are. I can search your posts by your username because YOU choose to create an account and post under that account. I can't see what posts you made as an AC. Or what moderations you have done.

All your actions outside posts made under your account are unknown to me, unless YOU somehow share them AND link them to this account. You could be Obama for all I know, or be Lady Gaga. Now, I could google your nickname, but that only works if you used the same nick somewhere else.

It is possible to analyse all your posts and from them deduce a profile based on your style of writing. To be fair for the average slashdot poster that would put their location as "nearest kindergarden" but it might be possible to trace you to a specific location.

BUT that is because YOU choose to link all your posts together.

On the other hand, in the real world, I can't go invisible when I leave my house. So my neighbours know when I come and when I go. The supermarket can tell what I am doing by what I am buying. The bookshop knows my reading habbits (you sicko, is their personalized greeting) etc etc.

So, why do people worry about their online visibitlity where you can be a million different people, when everyone and their dog knows your offline person and what it is doing?

If you ever lived in a small community, you are used to it and you know, if the community is good, then it is a benefit. Neighbours actually stopped an attempted burglary because they knew I was away and saw movement so knew it couldn't be okay when I was younger and lived in a "village" that was about a dozen houses. In Amsterdam I had a neighbour discovered after the smell from the rotting corpse finally drifted into the hallway. All I knew was that the previous resident had moved and nobody ever noticed the new person moving in.

Don't complain about invasion of privacy is you broadcast every fart you make to the entire world. It is like saying "how dare people look at me when I streak down the high street".

Tim's watch is broken

What steps will reproduce the problem? 1. Find Tim (he's usually in the Seattle office) 2. Engage him in conversation 3. Surreptitiously try to check the time on his watch  What is the expected output? What do you see instead?  Expected watch to tell correct time.  It tells the wrong time.  Please use labels and text to provide additional information.

Can you please provide us with some more details:  Has anybody else observed the same issue? Is the watch still broken, if somebody else wears it? Does the watch show the correct time in another time-zone? How about in a different country? Does the watch show the wrong time for all supported language markets? Have you ruled out the possibility of it being a simple rendering issue? Does the issue repro with other watches Tim wears? Is there any other equipment that might be interfering with the proper functioning of the watch? Have you ran recently virus scan? Can you please paste the output of 'uname -r' for both the watch and Tim? When was the last time the watch was synced?

Stay away from the border ..

Even if you are legally in the US: While planning travel, avoid border towns and the routes close to the border. Stay away from Arizona, upstate NY, areas of Texas ..

The Lake Shore Limited runs between Chicago and New York City without crossing the Canadian border. But when it stops at Amtrak stations in western New York State, armed Border Patrol agents routinely board the train, question passengers about their citizenship and take away noncitizens who cannot produce satisfactory immigration papers.

You Paid What for That Flight?

Great Divides

When troops must be motivated to fight, “go team” speeches often invoke an ancient conflict, along a great divide:

Our fight, of [A] against [B] over [C], is but one battle in the ancient war over [F], along the great divide between [D] and [E]. Many do not realize how many of our apparently mundane conflicts are, in reality, battles in this ancient war. Today is a crucial day in this war, so we must not give up, and we must not lose hope, or someday [D] may lose [F] forever. Fight, fight!

Some classic great divides: tyrants vs. freedom-lovers, rich vs. poor, faithful vs. heathen, urban vs. rural folk, men vs. women, intellectuals vs. ignoramuses, artists vs. undiscerning, greens vs. greedy, civilized vs. uncivilized, east vs. west, farmers vs. herders, hill vs. valley folk, Aristotle vs. Plato followers, jocks vs. nerds, extroverts vs. introverts, neats vs. scruffies, makers vs. takers, communitarians vs. individualists, young vs. old, [can add more here].

Some questions, which I rarely see adequately answered:

1. How is this division a key division, underlying many others?
2. How do people acquire their sides in this conflict?
3. How has this conflict lasted so long, without one side winning?
4. How could one side finally win such an old conflict?
5. Why is one side better than the other in an absolute sense?
6. Why can’t those folks be persuaded that their side is bad?
7. Why can’t peaceful compromise replace conflict?

make new wheel with rocks?

"So, what kind of rock should I get? Granite? Sandstone? And which quarry should I get it from? I was thinking that granite would last longer but sandstone would ride nicer and would be easier to lob at a dinosaur in case of attack."

Wheels made from rocks are quite a demanding application. Most rocks are very strong under compression (e.g., in a building or wall), but many are relatively weak under tension [wikipedia.org] with low elastic [wikipedia.org] strength, and therefore they will break relatively easily when a wheel is sheared laterally, such as when rounding a turn (due to forces acting perpendicular to the direction of travel). A way to mitigate this is to make the wheel rather thick, but the disadvantages (weight) are obvious.

Granite [wikipedia.org] is probably a better choice than sandstone [wikipedia.org] because most sandstones have individual grains that are in contact only over a small part of their area, with the spaces in between cemented together by other minerals that are often quite soft (e.g., calcite). Worse, many sandstones don't have those spaces fully infilled (i.e. the sandstones are porous [wikipedia.org]), which does increase their elastic modulus [wikipedia.org], but makes the material more prone to surface wear (it's easier to rub the mineral grains off the surface -- and it's even worse if water freezes in your neighborhood). Cracks tend to propagate [wikipedia.org]easily in sandstones. By contrast granite and other intrusive igneous rocks [wikipedia.org] are comprised of mineral grains that grew together as the molten rock crystallized and therefore the grains interlock quite tightly with virtually no open spaces between them (i.e. they are holocrystalline [wikipedia.org] and often equigranular [about.com]). A downside, however, is that some of the more common minerals in many granites (e.g., feldspars [wikipedia.org] and micas [wikipedia.org]) have good mineral cleavage[wikipedia.org] (it's not what you think, it's planes of weakness in the crystal structure), and the more coarse-grained granites therefore tend to break more easily (because the cracks propagate along the relatively large, weaker cleavage planes in the large grains). One way around this is to look for a granite with less of the minerals that have cleavage (i.e. less feldspar and mica) and more of the minerals that don't (e.g., quartz [wikipedia.org]), and to choose a granite that is as fine-grained as possible (then the random orientation of the cleavage planes from grain to grain will mean the cracks can't propagate as far along them before bumping into a grain boundary). As a bonus, quartz has a greater hardness [wikipedia.org] than feldspar or mica, so frictional wear will be reduced too. Therefore, a nice, fine-grained quartz-rich granite (ideally a quartzolite, but they are quite rare) is probably your best granite option. A fine-grained, non-vesicular [wikipedia.org] mafic [wikipedia.org] igneous rock, such as a basalt [wikipedia.org] or diabase/dolerite [wikipedia.org], might work well too, although they have higher density and don't have significant quartz (but the very small grainsize partly offsets this).

But why limit yourself to granite or sandstone? You can get all the benefits of a quartz-rich rock by going for a lithology [wiktionary.org] that is even more quartz-rich than granites. For example, a metamorphosed [wikipedia.org] quartz-rich sandstone will have the sand grains much more tightly cemented together than a typical sedimentary rock. These rocks are known as quartzites [wikipedia.org] and are much, much stronger. So strong, in fact, that your biggest challenge will become carving the rock into a wheel shape with the tools you've got (even bronze tools would be a struggle). You might be best off doing it the old fashioned way, and using quartzite tools to carve your quartzite wheel.

To find a nice deposit of quartzite your best bet is probably to find a location where quartz-rich sandstones have been heated up adjacent to a major igneous intrusion, thus producing contact aureole [wikipedia.org] in the sandstones where the rocks are metamorphosed into hornfels [wikipedia.org]. Basically, if you already know what granite looks like and already know what sandstone looks like (and it sounds like you do), then look in the area near the contact between the two. That will probably be the best stuff for the application you have in mind.

You've suggested using rock for your wheel, but in the end, you're almost certainly better off making your wheel out of a modern, light, composite material such as wood. A lighter wheel such as this would also allow you to flee faster should your attempts to throw rocks at the attacking dinosaurs fail.

I hope that helps. Good luck with your project.

iPhone keyboard

Recently I bought something called an iPhone. It drops calls so often that I no longer use it for audio conversations. It's too frustrating. And unlike my old BlackBerry days, I don't send e-mail on the iPhone because the on-screen keyboard is, as far as I can tell, an elaborate practical joke. I am, however, willing to respond to incoming text messages a long as they are in the form of yes-no questions and my answer are in the affirmative. In those cases I can simply type "k," the shorthand for OK, and I have trained my friends and family to accept L, J, O, or comma as meaning the same thing.

iPad vs Pebble

To judge the usefulness of the iPad you can't compare to Android tablets, but to things that are already available now. This is a comprehensive list of the features between the Apple iPad and your typical Pebble.

Pebble (40,000 BC) features:
Multitasking - no
Camera - no
Flash - no
Windows Apps - no
Removable Battery - no
Optical Drive - no
Ugly bezel - NO
Color selection - VERITY OF DIFFERENT COLORS
Battery life - INFINITY HOURS
Weight - 0.01 LBS
Cost - $0

iPad (2010) Features:
Multitasking - no
Camera - no
Flash - no
Windows Apps - no
Removable Battery - no
Optical Drive - no
Ugly bezel - YES
Color selection - NONE
Battery life - 9-10 Hours
Weight - 1.6 LBS
Cost - $499.00 to $829.00

Note I'm only comparing features, for example I do not include things like touch screens as its not a feature, but a way to make available features more accessible. The pebble actually has a very intuitive and simple design interface. Much more user friendly.

In summary if your choosing between the Pebble and the iPad, they both are similar in feature sets, but the Pebble beats the iPad in Weight, Battery-life, portability, and variety. However the iPad has an ugly bezel around the screen, but than again the iPad is $499.98 to $829.98 more expensive.

In Praise of Idleness

One of the commonest things to do with savings is to lend them to some Government. In view of the fact that the bulk of the public expenditure of most civilized Governments consists in payment for past wars or preparation for future wars, the man who lends his money to a Government is in the same position as the bad men in Shakespeare who hire murderers. The net result of the man's economical habits is to increase the armed forces of the State to which he lends his savings. Obviously it would be better if he spent the money, even if he spent it in drink or gambling.

The idea that the poor should have leisure has always been shocking to the rich. In England, in the early nineteenth century, fifteen hours was the ordinary day's work for a man; children sometimes did as much, and very commonly did twelve hours a day. When meddlesome busybodies suggested that perhaps these hours were rather long, they were told that work kept adults from drink and children from mischief. When I was a child, shortly after urban working men had acquired the vote, certain public holidays were established by law, to the great indignation of the upper classes. I remember hearing an old Duchess say: 'What do the poor want with holidays? They ought to work.' People nowadays are less frank, but the sentiment persists, and is the source of much of our economic confusion.

the real trick is ..

“Below 60,000 dollars a year, people are unhappy, and they get progressively unhappier the poorer they get. Above that, we get an absolutely flat line. I mean I’ve rarely seen lines so flat.”

“Clearly… money does not buy you experiential happiness, but lack of money certainly buys you misery,” he said. But the real trick, Kahneman said, is to spend time with people you like.

The Tyranny Of Compulsory Schooling

Let me speak to you about dumbness because that is what schools teach best. Old-fashioned dumbness used to be simple ignorance: you didn't know something, but there were ways to find out if you wanted to. Government-controlled schooling didn't eliminate dumbness - in fact, we now know that people read more fluently before we had forced schooling - but dumbness was transformed.

Now dumb people aren't just ignorant; they're the victims of the non-thought of secondhand ideas. Dumb people are now well-informed about the opinions of Time magazine and CBS, The New York Times and the President; their job is to choose which pre-thought thoughts, which received opinions, they like best. The élite in this new empire of ignorance are those who know the most pre-thought thoughts.

Mass dumbness is vital to modern society. The dumb person is wonderfully flexible clay for psychological shaping by market research, government policymakers; public-opinion leaders, and any other interest group. The more pre-thought thoughts a person has memorized, the easier it is to predict what choices he or she will make. What dumb people cannot do is think for themselves or ever be alone for very long without feeling crazy. That is the whole point of national forced schooling; we aren't supposed to be able to think for ourselves because independent thinking gets in the way of "professional" think-ing, which is believed to follow rules of scientific precision.

Modern scientific stupidity masquerades as intellectual knowledge - which it is not. Real knowledge has to be earned by hard and painful thinking; it can't be generated in group discussions or group therapies but only in lonely sessions with yourself. Real knowledge is earned only by ceaseless questioning of yourself and others, and by the labor of independent verification; you can't buy it from a government agent, a social worker, a psychologist, a licensed specialist, or a schoolteacher. There isn't a public school in this country set up to allow the discovery of real knowledge - not even the best ones - although here and there individual teachers, like guerrilla fighters, sabotage the system and work toward this ideal. But since schools are set up to classify people rather than to see them as unique, even the best schoolteachers are strictly limited in the amount of questioning they can tolerate.

The new dumbness - the non thought of received ideas - is much more dangerous than simple ignorance, because it's really about thought control. In school, a washing away of the innate power of individual mind takes place, a "cleansing" so comprehensive that original thinking becomes difficult.

bailouts work!

The past year saw an increase in the number of billionaires, from 793 to 1,011, Forbes said. The number is still lower than the record 1,125 billionaires recorded in 2008.

Not only are there more billionaires than last year, but the ones at the top are even richer than last year. The top 10 billionaires have a combined net worth of $342 billion, up from $254 billion in 2009, Forbes said.

There are more billionaires with a lot more money. Bailouts work! What more proof do you need?
