Guys, if you are seriously thinking of using this platform, and even forget security from a technical aspect for a moment, there are a lot of very basic trading and social-engineering questions that need to be answer by zhoutong and bitcoinica before you deposit money into this account:

1) Who are zhoutong and bitoinica? Where is this based out of? I went through the web site and it doesn't seem to mention this. Is he really who he says he is? A 17-year old who built a sophisticated web site in 1 week by himself? Why did he say that he built the web site himself, but in the blog of bitcoinica, it's written as "we"?

2) Why do they deposit everyone's money into a single account? Who owns this account? How do they keep track of everyone's money? REAL brokerages have people's money in segregated accounts, meaning that the brokerage firm CAN'T TOUCH THE MONEY even if they collapse. How do we know they won't one day turn around, transfer the money to China or Singapore and disappear? How do we know this isn't another Madoff case?

3) How the heck does he afford to give everyone 5:1 margin? The simple story of using the money that no one else is using doesn't fly, it's not that easy. You need to have excess capital in order to do this. What is bitcoinica's excess capital?

4) They do NOTHING to ensure counter-party risk!! What if Bitcoinica implodes and goes under? Again, what is their excess capital to ensure that customers don't share in any losses? If they suffer a catastrophic loss from bad trades, is that loss divided amongst all the customers?

I'm not saying they are crooks. I'm very interested in their platform, because I do a lot of algorithmic trading, so I'm familiar with this. I just want answers to these very basic questions before I deposit any money into this thing.

I believe FizzBuzz was first brought to attention by Jeff Atwood in his Coding Horror blog http://www.codinghorror.com/blog/2007/02/fizzbuzz-the-progra....

When interviewing, we'll generally ask questions about data structures and class design (design a card game), very basic looping and guards (do FizzBuzz), iterative vs. recursive programming (implement Fibonacci using both), and sometimes we will throw some discrete math problems in there too. These questions, coupled with making a strong effort to really get to know the candidate (is this someone you want to spend a lot of time with?) can really help for effective hiring.
In my team's case, the only problem we had was having to modify a bunch of decorators that implemented the java.sql.Connection interface. They added a bunch of methods to the interface in the upgrade.
Thanks a lot. Now it's blurred out..
In retrospect this was a transitional phase for Apple since the Macbook is no longer offered. Even at three different models it is still far less complicated than the rest of the industry.

> Whether you're a bad person or not is not for me to say, you can make that judgment for yourself.

If you're not saying that these people are "bad people" then what's your basis of demanding that their actions be illegal?
While I agree with you, I don't think 99.5% of the population owns a mac.

There will always be a benefit to being able to choose. I'd rather have to acquire knowledge, and be able to make an informed choice - than have someone else make that decision for me. I know I'm not the only one.

EDIT: Okay - so why the down-vote? Commenting on any Apple-centric post, with any comment that can be considered even slightly disparaging towards Apple is hazardous.

When it comes to Apple, some people seem to end up exchanging their brains for shiny-hardware. Depressing.
I got that impression from the article. I also get that impression from all the companies that still do the opposite, today, as is discussed in the article.

Perhaps I should have qualified that statement with "in terms of large american companies", which is what Drucker was talking about.... Companies whose product catalog became bloated over the years in an effort to serve every need of every customer and ended up doing nothing terribly well.

First off, I take issue with starting an article by citing an emperor from over 2000 years ago to bolster a claim about a modern government.

That said my brother is in China now, and I setup a squid proxy for him using AWS (in singapore). Unencrypted it does no good, facebook and youtube actually cause the proxy to stop working for him briefly (without a proxy its a coinflip wether they will load or not).

So he just sent me a public key so I can setup an SSH tunnel. That should do it, too bad it's impractical to set up 1billion+ SSH tunnels for the citizens over there!
That's hilarious. Is this seriously the case now?

Popular music has a similar dynamic. The studio model is to grab a bunch of likely artists, get them in front of the public and see which ones get traction.

Restaurants are similar. Only about 50% will get traction and survive. That is a well studied business with a replicable model and still it's a crap shoot.

You might even extend it to HN style startups. Lots of expertise in choosing, funding, and guiding, but you still can't say with confidence which will succeed.

String Matches in Regular Expressions
I understand your concerns. Many people coming from Forex trading have such concerns. But the Bitcoin market is very different. Many people choose to be anonymous.

There're currently no explicit laws regulating Bitcoin transactions and Bitcoin trading.

All these points apply to Mt. Gox or TradeHill as well. There are no law restrictions on this kind of trading.

I use "we" because I represent my company xWaylab Inc. (registered in US). I'm the sole developer and project manager but I'm not the only shareholder.

For margin part, since we offer short selling, generally the combined portfolio is quite balanced. Currently our finances are quite healthy. We will never bet against our clients.

I don't really hope anyone will set a double standard in the Bitcoin market. I think everyone is a fair player. You can choose not to trust Bitcoinica if you're skeptical. But a few dozens of people have chosen to give us a try and they have deposited thousands and thousands of dollars.

Believe it or not, Bitcoinica is currently the third largest Bitcoin Trading Platform, following Mt. Gox and TradeHill. (8000+ BTC traded within merely 48 hours of establishment.)

I still believe in time. If Bitcoinica is still around after a few months, maybe there will be more people joining in.
I used the think the exact same thing. However, after spending some time with tools that do consider white space significant (coffeescript, haml, sass) I have come to prefer it. It's part noise reduction and part consistency between devs and environments that I prefer.

How technology could be destroying jobs
I studied economics in college and I recently had a thought on how technological change could explain some of the current unemployment crisis and I want to hear your thoughts. Could some of the current unemployment be caused by the differences between the rate of technological change and the rate of people's ability to adapt to new technology? If the rate technology replaces jobs, is faster than the rate people can adapt to the new economic/technological landscape, could this explain a portion of unemployment?
What you're describing is anecdata. I could drive down the street and say that 100% of churches in Georgia are Baptist and it would make as much sense. And your anecdata doesn't match my own.

> We can’t recommend this enough: reuse the same template for all language versions

This can get quite tricky, because languages don't easily map onto 1-to-1 items that can be just translated independently and stuck into a template. See the classic "localization horror story": http://interglacial.com/tpj/13/ (and HN discussion: http://news.ycombinator.com/item?id=2095334)
I'm not sure that Gruber explicitly stated this, but it also seems clear to me that a key design element -- making the device small -- is also enabled by the lack of configurability. If there's no concern for assembling interchangeable parts, the parts can be integrated into a tighter enclosure.

Did you check your link? It looks like the average salary for teachers is about average for America.

That puts them well below the mark where they'd need to be to be to place in the top X% (10-30, depending on what study you use) that own 80% of American wealth. If you believe that shuffling around the remaining 20% will work, more power to you. But I'd have to disagree.

I will, however, agree that politically connected insiders mooching off the system is DEFINITELY an issue in the US. I would just point to Corporations and the Rich in place of Teachers on your list.

It's an interesting question, and not an easy one to answer policy-wise I assume.

My 2 cents are that opening up a country is more effective than isolating it. I've been to China several times, and there are a lot of people living good lives out there, even by America's standards. As oppressive as internet tech communities like to make it sound, it is still more than possible to do business, make friends and have interesting political debates (even on subjects like democracy) over there.

I am a vehement supporter and believer in free speech, and I do not like the practices they have implemented over there. I just do not believe that cutting China off completely would solve anything (China has cut them selves off a couple times, you can read about how it worked out for them).
I think you're underestimating-- making a movie is really, really hard. It barely matters how much the camera costs. Producing video of the quality audiences now expect takes dozens of people who all know exactly what they're doing. That's the major expense.

Anyone with a PC and a HD camcorder can easily produce good video for, say, the early 90s. But people now don't want to watch video from the early 90s, so it still costs a hundred million bucks to make a film.

Technology doesn't "replace" jobs. It increases our productivity, meaning we can do more with less and sell better for cheaper. The net effect is positive.

That said, there is always a lag in how quickly society can adapt to new tech, which may result in unemployment temporarily above the natural rate. And during these times, people tend to hate on new technology:

Until 1975, labor was the most scarce resource. Post-1975, technology was the most scarce resource.

A bridge needs a thousand people to build but the idea of a personal computer only takes one genius to bring into fruition.
That is the core of the problem, yes. But, lots of luck to you if you get anyone in mainstream media or high academic standing to admit it -- let alone to talk about it or anything closely related.
Most people drive their car without knowing how an internal combustion engine works. Most people watch television without knowing that the picture is comprised of pixels (or scan lines). Is that also sad? Must everyone understand everything they use in sufficient detail?

Why should a computer be different?

Why should my mum need to understand what an operating system is, let alone care about it?
Taking only 1 year as an example, 2001 Amazon had $444 million of accounts payable, $305 million of current liabilities (some other things...) and 2.1 billion of long term debt.

So, in 2001 the total current liabilities and ltd was over 3 billion dollars.

So they borrowed - they issued bonds as well as used other types financing. The interest payments for that year are actually pretty low in relation to the debt, interest expense for 2001 was only about 139 million.

You're here linking benchmark charts, because as a power user you believe power users represent a large subset of computer owners. We don't. We're in the minority.

My girlfriend, and everyone else in the humongous non-power-user subset, does not care about how a Vertex 3 can bury an Air's SSD. She doesn't know the Vertex exists! If she did, she'd probably ask why she should spend $300 on it if her Air already works amazingly well.

We're talking about different groups here. You're talking about the type of people who read computer hardware blogs like Anandtech. I'm talking about everyone else in the world.
I think you're looking at it the wrong way. I'm sure that if you were in Apple's position you wouldn't take too kindly to everyone imitating your designs and technological innovations. Companies do have to make money.

You could argue that Apple is too controlling and sometimes they do go too far but that controlling nature also allows for superior products as well. I don't think the perfect solution exists out there for you.

>...forbid developers to talk about the OS...

I'm not exactly sure why you have a problem with this. Yes, devs are asked to sign an NDA but it's their choice to do so and I've yet to see Apple publicly go out after devs for violating their agreement.

> wished some PC maker should make a line of designed PC and deliver them with a raw Windows, without any crapware installed...I talked about it with a friend who is an Apple fan. His opinion was that it couldn't work because PC buyier didn't care...

They don't care. Have you ever tried teaching the average user how to use a computer? The typical response is "I don't really care. I just want to do x". Try selling them on spending a $1000+ on a computer that will only last 3-4 years. They don't see the value proposition and, for those that do, will buy an Apple product because of the brand image. The PC has lost the high end for almost a decade now and I don't think they can get it back. This, along with Apple dominating the supply chain, makes it difficult to compete.
I understand why they wouldn't want to serve ads on Wikipedia, but isn't it a bit hypocritical to say the choice is so they can maintain editorial independence? Because for someone who wanted to influence the foundation, donations are probably just as good a way to do so - it just forces them to be more straightforward about it.

c) people issuing the debt make money on the deal so they have incentive to push and not as much if a failure.
You mean like how the competition has caught up with the iPad? Oh, wait...

edit: Also, they've been selling the iPhone 4 for a long time now, it has sold better than all of the previous models, and it's still selling incredibly well in spite of the expectations that a new model will be released soon. Doesn't really seem like the "one size fits all" approach has backfired on them at all, especially when that one size fits so well...

another edit: "there is currently no competitor to the Apple products he's discussing"...isn't that part of the point he was trying to make? That other companies are unable to compete currently because they don't control their supply chain as well or as tightly as Apple is able to, as Apple only offers a few options as opposed to the overwhelming amount of near-useless (to the average laptop buyer) options that the other guys offer?
> Cyberpunk is largely an expression of fears about an Asian (Japanese more often than not) "takeover" of Western society. It's actually very xenophobic but it does reflect the dystopian fears of the time. Cyberpunk has waned in recent years as the xenophobia has and the realization that this isn't the future.

This is way off base, and really does a disservice to those authors. Cyberpunk in the 80s may have inherited some economic xenophobia but there were a lot of other ideas in there that I think were more important and continue to be, around the internet and technology.

It also hasn't waned the way you describe. The Deus Ex games are examples of cyberpunk that doesn't have as much to do with Asian takeovers of Western society as Neuromancer or Snow Crash perhaps does. Aside from the technological themes, the demons are thoroughly all-American: media propaganda, military contractors, corporate regulation, big scary government, war on terror, police actions... I would argue a lot of that came from the dystopias envisioned by sci-fi in the 80s, some of it from the cyberpunk authors.

I agree about Neuromancer being fairly average in quality, and that CJ Cherryh should be on the list.

I love your candidness in your post. I think many hackers will immediately relate to the things you're feeling, myself included.

A note on co-founders, partners and others: I think a lot of times a second pair of eyes can really help, someone you can bounce ideas off of, etc. Sometimes all it takes is a fresh perspective on your problem to really get past the hump, and that's where a co-founder can really shine. Keep that in mind as you charge on, best of luck.
