How much did he spend on the 105 GPUs?

From this calculator: http://dustcoin.com/, you need about 60,000 KH/S to make $114 a day (excluding power cost). One of the most efficient $/hashrate GPUs for litecoin mining is the ATI 7950 at about $210 a piece and ~600 KH/s. 105 * 600 KH/s = ~60000 KH/s = ~$114, so it works out. That's $20,000. So if you spend $20,000 you can buy yourself a job that pays $114 a day. It will take 6 months just to break even. Better hope the difficulty hasn't increased enough in that time to make your GPUs irrelevant (hint: it probably will).

Keep in mind that I was very generously excluding the very significant cost of power, the very significant cost of all the motherboards/cpu/ram/power supplies to run those GPUs, and the power and space required to cool them. Realistically we're looking at more like $50k.

>“Currently I’m making about 60 litecoin per day,” he said. “I’ve kept 95% of the mining profit since April and once the major exchanges start accepting LTC, others will follow, and price is expected to soar. So that 60 LTC could turn into $1,500.”

This is absurd. If he thinks 60 LTC will be worth $1,500, he should spend the $20,000 he spent on GPUs on LTC instead. He'd turn $20,000 into $250,000 with no work required (another hint: assuming you can turn $20k into $250k in 6 months with no work as a sure thing is also absurd).
Looks like beautiful Florence! Is it?
Ah, but what does $114 a day buy you in Jakarta? If it pays for your housing and expenses, that's not a bad way to spend an extended beach vacation...

Edit: Also, depending on how you want to look at it, the hour value is a bit off. $114/day * 7 days/week / 40 hours/week = $19.95.
Agreed - and this is a hugely important effort. This is more me musing about replication vs. reproducibility (on the computational/statistical end) vs. repeatability.
False equivalency.

It was only the House Reps who were claiming the moral authority to hold a gun to the head of our economy, in order to squeeze concessions that they cannot possibly win by any normal legislative procedure.

Senator Reid could choose to do so. He does not, because it would be stupidly disruptive to create a crisis for a debt ceiling.
Plus, the target market doesn't likely have storage space for both their existing bike and a pedal assist model. If I'm a city-dwelling hacker, I'd prefer buying a wheel over a scooter. I just pulled up listings on Amazon for inexpensive e-bike pedal assists, and they're mostly largish scooter-types that take a significant footprint to store compared to a bike which I can hang on my wall.

Plus, having a wheel allows me to continue using my tires, frame, accessories and everything I love about my current commuter bike.
The article certainly seems wrong. Other than Hawaii which is an obvious outlier (36.61) the most expensive mainland electricity in the US is in California at 16.71.

http://www.eia.gov/electricity/monthly/epm_table_grapher.cfm...

In the Europe the story is quite similar. The country with the most expensive electricity is Denmark at 29.5 but most vary between 10 and 20 cents.

Insider attacks are definitely not a solved problem for banks, insider attacks or cooperation with insiders are a major part of realized fraud losses.

For banks (unlike data companies) the most effective anti-fraud tools are actually not about prevention, but detection and mitigation. Well, also insurance and prosecution.

Diceware uses a set of 7776 words. You select words from the list using 5 dice. 5 words, picked using 5 rolls of the set of 5 dice, gives you about 64 bits of entropy.

> A five-word Diceware passphrase has an entropy of at least 64.6 bits; six words have 77.5 bits, seven words 90.4 bits, eight words 103 bits

Because our attacker knows that we've used Diceware, and knows what diceware wordlist we used, and knows that we've used a 5 word passphrase, there are 7776^5 phrases to try. That's 28,430,288,029,929,701,376.

I'd be interested if you think Diceware is broken.
Kevin Roose clearly misunderstands what "functioning" means in Congressional terms. Perhaps he was absent on the day that his 4th grade class learned:

- The Executive branch enforces laws.
- The Judicial branch interprets laws.
- The Legislative branch makes laws.

Think about that: The Legislative branch's ONLY JOB is to make laws. Now, I'm a big-government-loving bleeding heart liberal, but even I have to admit that it's completely ridiculous to put 535 people representing 3.8 million square miles of land into one building for 11 months out of every year for the sole purpose of making new laws. How could you not end up with tons of unnecessary cruft and bloat?

What this means is that the only time we aren't adding more restrictions to our lives is when Congress is gridlocked. Gridlock is the system functioning as designed. What's not to love about it? We don't want a government that moves fast and breaks things. For startups and lean companies, it can be a real pain in the ass! It's hard enough to keep up with compliance issues when you're just starting out; having to change your policies every 6 months due to the whims on Congress would be practically anti-business.
Thanks for your interest.

It will do in the second iteration. This is the core product so has security, post, like, favourite, see other peoples code, profiles, search, leaderboard and some others.

Revolving door strikes again. They probably will join Booz Hamilton or one of these large contracting companies and rake in the money. Same old.
I live in New York and we have tons of bike shops. Actually the area I live in attract a fair number of tinkerers and it's not unusual to see some weird contraption affixed to a vehicle that was formerly a bike. And used bikes in pretty good condition are bought and sold here ( sometimes even bartered ) for $180 - $300.

I can totally see this taking off here.
I encountered it in university, though the example was given in a freshman level course by some kid who thought he was cleverly circumventing information's speed limit. The professor seemed quite pleased with it.

Well, the government can ask them not to do end to end encryption in the first place; and it's likely that MS values their desire above yours.
> Now that everyone uses Facebook, Gmail, Amazon, Twitter on a daily basis, the average person thinks of those as simple 'websites', that are easy to build.

I'm really surprised that people actually look at the websites of multi-million dollar internet-only companies and think it must be easy to build something worth that much.
Here's a good reason: in April 2014, Microsoft stops issuing security patches for XP. At that point, any exploits people find(and they will find them) will never be fixed. Your computer will be the easiest target out there.

Not just will this be bad for you(assuming you value your files or do banking on your laptop), but if your compromised computer starts hosting a botnet or attaches viruses to your emails to friends, it's a problem for everyone.

It's a similar problem(though not nearly on the same level) as people who refuse to vaccinate their children.
I think I understand your point, but the statement has been falsified many times throughout history. Many corporations have prospered on human misery and death.
This is precisely why web-hosting providers exist. You can find someone to host most of the common CMSs, you can certainly find a company that will run a web server on your behalf (so you can deploy a static site). If you really want a tuned WordPress installation there's WPEngine.

If you don't want to deal with the installation and configuration of the underlying software, don't lease a VPS or any other type of server ... lease a "service".

EDIT: I completely forgot about sites like Weebly. You don't even have any research to do with this type of solution as you just use what you're given.
This is less efficient than putting all the batteries and other gear on the frame, right? Spinning all that mass around will take energy. I don't see an advantage unless you expect to swap wheels out often.
Well, I know for a fact that the Leaf also uses an AC motor with an inverter. It's documented all over the place. But, they have permanent magnets in theirs, while Tesla apparently does not.
A GPS module is of course also located on the Smart Wheel itself so it sends a signal on its own once the motion sensors (that turn on only after you lock it) notice it's moving without your knowledge.

The top speed means exactly that - because the Smart Wheel is a pedal assist this means it helps you accelerate until you reach 20 mph and no further. You're correct in stating that the top speed is also set in accordance to the US Law (or European Law, which allows for speeds up to 25 km/h).

We're sorry about the confusion about "the first line of electric bicycles" - this was of course meant to inform the reader about the first line of e-bikes that we're introduced by FlyKly, not the first e-bikes EVER.

I am no physicist, but could they decay into a virtual Z boson, which imparts momentum onto a nearby real particle?
Battery life of 1000 cycles? Isn't that a bit low considering it'll only take you about 30mi/50km per charge cycle?

If they had some way of restoring the batteries without replacing/repurchasing the wheel, I'd be less concerned.
> I personally would prefer a model which only gained energy from the rider when coasting down hills or braking

But then you gain nothing, on average.
Not sure if I did a good job of explaining things in the post, but the point is that, this is the requirement for hospitals/doctors who are already on electronic records. So, you're on electronic records, but your requirement for sending data electronically is a pdf? Feels like a huge lost opportunity.

And the problem of "closed" systems is exactly what we're trying to solve with Trace Health (not to be too self promoting.) The proprietary systems aren't going away, but new government regs mean that patients are now going to be able to log in and see their data online (in crappy patient portals). We credential in on the patients behalf, pull the data out, normalize it with records from their other siloed, proprietary systems and then make it easy to understand, download, etc...

It's clearly not the way we'd architect our health care system if we were starting over, but hopefully a helpful hack for those of us who have no choice but to deal with the healthcare system as it is.

In theory, a neutrino colliding with an antineutrino is similar to an electron colliding with a positron. If the neutrino/antineutrino pair has enough energy, you could produce new particles. Otherwise, they'll just scatter off of each other.

Now, because electrons/positrons interact electromagnetically in addition to through the weak force, while neutrinos interact only weakly, how they scatter and the chances to produce new particles will be different. But the processes are conceptually similar.
That's true. One of our neighbors used to take out the front wheel just for storage when he got out of the elevator. There's just no room and folding bikes are still a little expensive (unless you're lucky enough to score a used one cheap that needed a bit of TLC).
The Smart Wheel actually consists of two halves one of which is fixed (it doesn't turn). The battery is therefore stationary and doesn't require any kinetic energy to be spinned around the axis.

The figures provided in WP are for a 1961 Encyclopaedia Britannica (EB). Modern studies of contemporary primitive people groups shows markedly different life expectancy figures and reasoning. For example the neolithic life expectancy drop is now not considered to have been as severe attributed to communicable diseases introduced by domesticating livestock not grain introduction -- I'd add that our sample size of Neolithic dead people is also pitifully small.

Another easy to research example, we know from historic records that life expectancy in 19th century Ireland was near the top of the table you provided in WP, but was considered quite low for the time period in Western Europe. Other data shows that by 1900 U.S. life expectancy was already ~50 which is almost double the figure provided by EB.

Another way to think about it is, unless humans rapidly developed an ability to handle grains in the last couple hundred years, life expectancy should still be at or around historic numbers, not at around double. People should still be dropping dead from diets of grains, but they don't. So an external causal agent other than grains (livestock domestication, introduction of alcohol, large scale warfare, highly virulent diseases) must be the logical conclusion.

The figures are off for Classical Rome as well. Depending on your social class life expectancy was around 40 for the lower classes and around 60 for the upper classes. Other studies show that if a child made it through their first 5 years, they could be expected to live to around 50 regardless of social class. It wasn't considered unusual to see people in their 60s and even early 70s even if the percentage of population in those ages was much smaller than today. But of course documentation isn't very good either leading to those conflicting figures.

Another case, Australia spent about 30 years trying to get the life expectancy of Aboriginals up to any kind of reasonable number. I believe the gap when they started studying it was about 20 years. Grains were not causing non-Aboriginals to drop dead before their Aboriginal hunter gatherer neighbors.

I'm generally suspicious of any expectancy tables for any population that don't start at around 35-40 for any time period. Numbers lower than that are almost always the cause of a catastrophic external factor like the Black Death. There are pitifully few well documented populations where life expectancy isn't at least in the 40s. This goes for hunter gatherer tribes to the most war-torn inhospitable genocide suffering places on the planet with access to virtually no healthcare and unbelievable infant mortality rates but plenty of grains.

The introduction of a staple bearing diet had little effect on life expectancy numbers directly, but enabled other advances which did.
My wheelchair-using family and friends have been rocking Alber e-motion wheels[1] for some time, and would highly recommend them. Those don't recharge from motion (or as fast), or support bluetooth, but work in a similar way.

1000 cycles of 30 miles is in average way more than an average commuter spends riding over a course of a year. We believe this distance is acceptable for a product with a one year warranty.

Of course the battery pack will also be easily replacable.

I personally believe the following things should happen:

1) increase the # of representatives. Why was the # capped? Now I believe there are an average of 700k per representative. I am going by memory here. But I know the original recommendation was 35,000 per rep as per the Constitution. This needs to be allowed. So what if we end up with about 6,000 representatives! At least we would have a more direct access to our rep.

2) House of Representatives shouldn't run for 11 months a year. Make it 6 or 7 months. Let them come back to their districts for one month every 3 or 4 months. They need to spend more time with their constituents.

You should ask yourself a few key questions:

1. If you're starting out do you have the time to do product dev AND a blog? Blogging can be very time intensive.

2. Is the blog part of your marketing or just a place to park notes about product releases?

3. If it's part of your marketing plan is a blog the best investment of your time and money? Does it give something to your audience?

4. Are you writing this blog, or is that the job of someone who is doing your content marketing?

I'd first figure the basics out then worry about hosting...

I have a nice, but very irrelevant story about potion.

After EuRuKo 2009, we were standing at the gate on the airport of Krakow, close to boarding time. why had just disappeared and so he was the topic for our group and one of us started to lament that he wanted to have a look at potion but it had just disappeared before he could download it.

Suddenly, Matz appeared, waiting for his plane going from the next gate. Matz loves programming languages and he had a copy on his notebook. So there we were, in Krakow, scrambling to find a USB stick in our bags to get a copy of potion while our planes were being boarded.

Some people collect wine, others collect programming languages.

This is a good overview, but a few things to note:

- Cuban was the largest shareholder

- Cuban was told that the company planned to offer a deal that allowed for more purchases at a 10% discount, diluting his stock. He was told this before the public announcement, and sold his stock the day before the public announcement.

None of this was really disputed. What was disputed was whether or not Cuban had a conversation that acknowledged he was an insider and that he couldn't sell, and whether or not there was an implied confidentiality agreement. This would suggest admission of guilt as well as satisfy the "misappropriation" definition of insider in the article you linked, since they couldn't satisfy the fiduciary definition.

So, he traded based on non-public, adverse information, and saved himself from a substantial loss. Despite this, the SEC failed to convince the jury that he fit any formal definition of "insider".

I think we can all agree that whoever bought all of his stock prior to the public announcement of the dilution did not have his advantage, and his advantage came solely from a position of privilege within the company.
So if you're within a few feet of your bike when someone takes it, it will notify you? And it will track the bike for a few seconds as it goes out of range?

Your KickStarter calls this "located and tracked" without caveats. That's pretty misleading.

My complaints about worshipping at the lean startup alter...

The lean model only leads you to local maxima. It can't discover any feature where the sum is greater than it's parts, or critical mass is required. I'm looking at the iphone as an example.

Critical mass is another apt analogy. Just like a fusion reaction requires a certain size to become self sustaining, some businesses require more more effort to start. Pivoting is the antithetical to getting the very largest and most valuable flywheels spinning.

Not that it doesn't have it's merits, but I think lean startups are oversold.
Electrically-assisted bikes are quite popular in Japan, although the Japanese bike market is so huge they're probably still only a small proportion of the total.

Your concept of what an "e-bike" is seems a bit of out sync with this product. This isn't a scooter, or a scooter-replacement, or something you use for drag-racing with your friends. This is a modest assist for a normal bicycle that helps take the edges off normal bicycling. When you're hauling two kids and a load of groceries up a hill, a little bit of help can be very appealing... but it doesn't have to be a replacement for human effort.

If anything, this product seems to fit in a space beneath existing e-bike designs, which might be more powerful, etc, but exist in far smaller numbers than regular bikes, and so offer far fewer choices as to design, style, quality, etc. By making it possible to just choose a regular bike and "add electricity," they've given the consumer who wants the convenience of an electric assist a huge increase in choice.

Only "10k" years ago? You are definitely reading that wiki page wrong.

Mitochondrial Eve lived 140 to 200 kya (kya = 1,000 years ago). Y-chromosomal Adam lived perhaps 388 kya.

Edit: I guess you are looking at common ancestor, not a bottleneck. Reading the page more I find that everyone has a common ancestor around 3000 BC or so. But that common ancestor probably wouldn't be the guy frozen in the ice. But I'm betting the Sentinelese people would mess up those estimates.
How would this work if the user didn't already have the app it's deeplinking to? Like if an ad in Pandora took me to a page in Hotel Tonight but I didn't have Hotel Tonight installed, then what?

Also, seems like a feature that could be added to one of the more popular in-app ad services without too much effort.

Most people don't discuss things in terms of their strict legal definition, but in terms of what actually happened. Your comment suggests that I could steal a car, but I am not any more of a car thief than your grandmother until I get caught and convicted.
