If you send the 'bad' coins into the 'known good' wallet, everyone can see it. So while the coins themselves are potentially indistinguishable for reasons similar to melting together all the gold you receive and chipping off a bit to spend, the entire account is now known to accept coins from a bad source. You can send any part of any coins in an account to somewhere else, so it's not really 'melting', but it's a useful mental picture for laundering bitcoins.

In real-world cases like this, you generally launder the money through untraceable sources, where they can re-enter the system from anywhere and be 'clean'. You can do something similar in bitcoin, where I think they're called "mixers". I don't know if any automated ones exist, but basically: mix (i.e., melt) a bunch of people's money from addresses A-M in one account, and send the same amount out to (brand-new, anonymous) addresses N-Z.

N-Z are owned by unknown entities, so as long as e.g. X doesn't receive exactly as much money as only D put in, you can't infer ownership. All coins are 'tainted' because the sources can be tracked perfectly (i.e., a marker chemical in gold), but who owns what coin is now lost. Obviously there's more to it, and distributing without losing perfect anonymity is difficult, but it shows the basic problem. Again similar to melting, you can even send # coins to addresses 1-9 over a large period of time, while melting more and more coins into the shared pool, so there's less of a chance of guessing who owns what based on timing.

I agree... to a point. Certainly, FOSS developers have it easier, as they can show the specific code they wrote.

But just as an actor can audition, developers (and most high tech folks) can demonstrate their skill in person. A lot of those "How would you solve this programming|logic problem?" tests are lame, but at least they do show someone how the person approaches her work.

Well, yes, I don't think it's feasible for Nokia either, because of the costs involved and because of politics.

However, all of us here that are familiar with the landscape and with Microsoft's history thought this was a bad idea from the beginning. A lot of people freaking told them so. This is especially infuriating since their N9 was a success, limited only by Nokia's decision to discontinue it from the start, with many reviewers calling it "one of the most fascinating phones of the last few years".

And Nokia is not a startup, but a big company that should have the resources to branch out a little and test the water with an Android phone. That's how smart companies are doing it - they are A/B testing competing solutions. Take a look at Google - that's still working on Chrome OS, in spite of Android being a success.

And I get that Nokia wanted to focus on fewer products, to preserve resources, however they've gone to the extremes, throwing away years of hard work and even consumer goodwill, adopting an operating system that they don't and will never control - at least with Android, if anything had gone wrong with the Google partnership, they could have forked it, just like Amazon did.

It seems Stripe is ideal for a partnering approach - have national established payment processors hook up to Stripes backend (after a vetting/selection process, of course). That way they can expand quickly without having to internalize the many different quirks of payment systems across the world.

Very nicely done! Selling books and training is a great way to get into products. My first ebook was released 2 weeks ago ($20k+ in sales so far).

To anyone wondering if they could do it to, the answer is yes. I can point to a dozen stories of successful ebooks that have made over $10k in 6 months. Not to mention to increase in credibility and readership that the author gains.

Here are my quick tips on writing a technical guide:

1. Find a topic that is in high demand. I chose designing iOS apps, anything related to popular programming languages or new technologies.

2. Talk about the value to the customer (time saved, better understanding, etc) rather than the features of your product (100 pages, PDF, ePub, etc). You need to mention the details of what the purchaser gets, but that isn't what will sell them on your product.

3. Don't just sell an ebook. Ebooks are cheap and simple or at least that is how they appear. Sell the book, but with it package code samples, video tutorials, expert interviews, and anything else that will give the reader a head start. This has the advantage of increasing the value of your product which helps with pricing.

4. Have more than one package. With my book I had three packages, with different amounts of extras in each. The base one included the book and a couple templates, the middle included 5 detailed video tutorials and more templates as, and the largest one had even more templates and code samples. Each package built on itself and the price increased accordingly.

Many people, and especially companies, won't hesitate to buy a more expensive package if it looks like it will save them more time.

5. Price high. My packages are at $39, $79, and $169. Setting those high prices is the best decision I made. The highest priced package has made almost as much money as the previous two combined. Jim does a great job with a price of $42.

I hope that helps anyone considering selling an information product like what many people on HN have done recently.

For reference you can checkout the sales page to see how my packages are organized: http://nathanbarry.com/app-design-handbook/

I've only been into bitcoin mining and trading for about a month now, so take this with a grain of salt, but:

If were the criminal behind this heist and I wanted to whitewash these bit coins, I would first establish several new wallets, would divide the coins between them, then would programmatically transfer the coins back and forth between the accounts in random amounts at short but random intervals over the course of several months to increase the noise level. I would then (again programmatically) buy a different electronic currency (namecoins, etc.) with them to obscure the trail even more. Finally I could transfer them back into bitcoins, using several new wallets.

At that point they could be cashed out or spent more or less freely.

Again, I'm new to bit coins so I may not know all the dynamics involved, but what I have outlined seems logical based on what I know at this point.

Interesting point to think about, however the % mix of funding source has little to do with whether employees of an organization are classified as civil servants. An example of this would be departments of transportation or other toll collecting public agencies - generally tolls and fees provide the bulk of the funding with taxpayer dollars making up a smaller percentage, yet the employees are very clearly civil servants.

Since UVA employees's salaries are publicly available through FOIA (see http://datacenter.timesdispatch.com/databases/salaries-virgi...) I think that's one pretty good indicator of civil service status. In Virginia, the University is required to report salary information, etc, to the Virginia Department of Human Resources Management. They are able to adjust how they report salary information for employees who are paid a portion through endowments and other outside sources.

Now, I have no idea or information about the specific case with Mann - who knows, maybe he was being paid exclusively by some special endowment and so his records would not be subject to a FOI request - but I would have thought they would have used that in part of their justification for not complying with the request.

Also - I don't consider myself a libertarian so I won't speak for them - I'm just a big proponent of government transparency.

Humans are far superior at many of the tasks that require more than just following an algorithm.

And autonomous air to air drones still need to be able to accept instructions/commands while in route, during combat, etc. The idea that we'll simply unleash 100 drones and create a killzone isn't something that's going to fly...

The reason all the companies are building and designing drones is because that what the governments/militaries are paying for. Private industry simply can't afford to do much R&D that isn't already contracted for by the DOD etc.

Finally, drones are easy pickings for manned aircraft. For permissive environments like the 'Stans and Iraq, sure. Up against someone with a real AD network, forget about it.

Exactly. The B2B markets are typically harder to penetrate for startups, unless the startup has plenty of cash to drag businesses to their product.
It's worth noting that people often typo things like billing address or cvc code, and that the majority of these failures are not in fact fraud. At that point, it's also a usability question about what the best behavior really is. The banks do take CVC into account when deciding whether or not to approve the charge, and obviously also run their own (often aggressive) fraud prevention algorithms to deny suspicious charges.

All that being said, we're working on some tools to make this a bit easier.

This actually makes a lot of sense. I mean, Microsoft is a gatekeeper on the Xbox 360 and enforces quite a bit of forced QA on every game officially released for the platform. If an Xbox 360 game crashes, I view it as a Microsoft failing, even if the game isn't developed by them. OTOH, if a non-Microsoft Windows app crashes, I don't blame Microsoft at all but rather the app developer.
Initialy no and it was never planned as such. I have not use iPlayer for many years now and was somewhat put of with the amount of network overhead it would impose for days after closing with requests for cached content from other users clients who still had your IP cached as active. Was akin to running a popular torrent and seeding for a while then suddenly stopping, only more so. I have no idea what it is like now and even if the option to pay for content or to login via account is there. But would not be hard to add given they have the content managment side fully tested now.

If it was not on there agenda initialy then your certainly right nowadays or at least it would be silly not to look at that opertunity to tap into overseas content base directly. Though they would need to have people login as currently I would hate to think how many VPN to get a UK'ish IP to use the service currently.

Interesting times ahead.
It still does not let you charge in US Dollars (Yes I know the customer can pay in what ever currency they want). But from a Canadian business point of view where your large section of customers are from US. Stripe is still not a very attractive option.

Funny thing about aircraft is that a well-designed aircraft can excel in many roles despite those roles not being part of the design spec. The F-16 was designed (at least in the YF-16) to be purely air to air. Turned out to be an excellent ground attack plane. F-15's motto was "Not a pound for air to ground." yet the F-15E Strike Eagles is excellent at strike and interdiction roles.
Actually, you can choose to charge in either USD or CAD, but you can only choose one with your account. If you need to charge in both currencies, for the moment we recommend creating two separate Stripe accounts.
What it's time for is site operators to stop consuming SEO "services". It's disingenuous, parasitic crap - and always has been.

It is a classic case of Jaron Laniers prediction that we will dumb ourselves down until the computers "pass" the turing test. You are giving up your choices and distinctions as a human being when you decide NOT to write what you want to write, but rather, write what the computer wants you to write.
The point of the article is that the first problem is not so much a problem and more of an afterthought compared to the more fundamental issues of spacing, proportion, weight, characters per line, and placement on the page, which all equal readability.

I strongly disagree. These decisions are never independent in practice, but if anything, I’d say the specific font(s) used in a design would influence choices of spacing and layout more than the other way around. For example, I don’t think you can choose leading or justification settings well without taking into account factors like the x-height and typical character widths in your text.

FindBugs [1] is a great code analysis tool for Java. It's free, open source, and supports plugins for writing your own checks. The FindBugs site reports an interesting story from a Google test day:

"Google held a global "fixit" day using UMD's FindBugs static analysis tool for finding coding mistakes in Java software. More than 700 engineers ran FindBugs from dozens of offices.

Engineers have already submitted changes that made more than 1,100 of the 3,800 issues go away. Engineers filed more than 1,700 bug reports, of which 600 have already been marked as fixed. Work continues on addressing the issues raised by the fixit, and on supporting the integration of FindBugs into the software development process at Google."

"Generally speaking, there are two ways (and only two ways) to scale a business to hit that $100 million threshold."

Actually, there's another way to hit >= $100M.

Be a strategic acquisition target. (Route two: The viral effect can overlap with this.)

I forget who blogged this (Dixon?), but the idea is that that to hit a >= $100M valuation, you should not be thinking of the standalone value of your business, but instead the value it provides to potential acquirers.

Sitting on crucial patents is one approach, but extraordinarily tricky.

More importantly, if your existence presents a strategic challenge to a larger player (e.g. Instagram), then your business is worth a lot of money.
Even slightly-delayed searching would be a huge deal, engineeringwise.
