I'm not a lawyer, but I know enough to tell you that the probability is zero. You can't be convicted of murder by omission, and you can't even be convicted of criminal negligence unless you have a clear duty to act, which is not the case here.

So say we're in the US, and I am walking down the street and discover you in a hole in the ground that is full of water, and you are obviously about to drown. There is a ladder next to the hole, and you ask me to put the ladder in the hole; let's assume that I can do so at absolutely no risk or even significant effort - all I have to do is press a button. If I don't you will surely die.

Well in the US, I don't have to do anything. I can stand there and callously ignore your pleas and watch you die and I won't get in legal trouble for it (although I will probably become a social outcast). Unless you are a member of my family or I am some sort of emergency worker or similar person with a responsibility to render assistance (eg if I invited you into my yard and you then fell into a hole), I have absolutely no legal obligation to help you - I can't be charged criminally, and your anguished relatives won't prevail in a civil lawsuit. There is no law against me being selfish or even sadistic (by passively enjoying your suffering).

Of course the moral thing for me to do is to help you get out of the hole, and most people would say that I should be even willing to risk some danger to myself in order to save your life. But the law is not a moral system, and the current theory at this point in history is that the limitation on my liberty by being obliged to incur risk on your behalf is worse than the fact that you may lose your life. This isn't entirely arbitrary; you read up on tort law you'll encounter a depressing number of cases where incompetent people made a good-faith effort to help and ended up making things substantially worse.

I would also like to point out that I personally prefer the risk of helping out to doing nothing, but have long since given up assuming the same thing about other people :-/

The Startup Checklist: everything you need to do to launch a startup
The worst part of it is that companies with bad unit economics are not just shooting themselves in the foot for the sake of "growth" or simply faking hotness, but that in acquiring users for more than they are worth they effectively drive acquisition costs up for everyone else in the industry.

Because the cost of electricity required to mine competitively is variable. When the price of bitcoins goes up, mining becomes more profitable. More hashpower is added by new and existing miners until it no longer makes financial sense to do so. The value of a bitcoin is almost always near the cost of mining one, but it's the value that determines how much mining there is.

Apparently the problem is 'The FDA grants market exclusivity to companies that are willing to take “grandfathered” compounds into compliance with their current regulatory framework'. Which is why they are able to force US buyers to pay $700 a tablet for stuff which is available for a few cents in India at the same time. I think the FDA might not really be doing US consumers a favour by preventing them shopping around.

Unless you're paying with bitcoins, you can't just teleport money. You need to transfer it via third parties. Credit cards do this and take a ~3% cut. If 21 can get its chips into every household, they can take a much smaller cut, especially since the chance that a customer won't pay their bill is lower. You'd have to unplug your mining chips to avoid a bill, which would instantly notify 21.

They can charge money to people's electricity bills and pay no fee. That is a competitive position.
For users who primarily care about extensions, but that's been true for a while. I rarely use extensions (currently I'm using, uh, Google Cast, plus the mosh Chrome app because life's too short to install software) and I care about security, and Chrome's multiprocess and sandboxed architecture has significant wins there.

When Firefox gets that, then I'd agree that at least for me, Chrome won't have many things above Firefox any more. And the new extension system is part of their plan for getting there.
I actually don't think a marketer touched this project at all.

Please note that the attack already shown in http://www.ijiss.org/ijiss/index.php/ijiss/article/view/58/p... in “Section 4 Security & Efficiency of CryptDB” in March 2014. It basically says that “First of all, CryptDB is open to frequency attack where the adversary knows the frequency of the plaintext. Namely, if the RND layer is decrypted to the DET layer in EQ onion, then the frequency attack is possible to apply because of deterministic encryption in the DET layer. In this attack, the adversary that observes the queries can determine the ciphertext simply by looking at the results’ row count. This attack can only be fixed by the RND layer, which has no usable functionality in practice. For example, assume that we have left part of Table 11, and its encrypted form is the right part in Table 11. By using the knowledge of the frequency, one can learn the corresponding plaintexts from the
right encrypted part in Table 11. This issue can be solved easily by using random IV based symmetric encryption, however, this will prevent executing all queries.“ You only apply the real medical data to show its practicality.

I'll pile on the bandwagon.

I just downloaded the dataset, and color is such a powerful feature that training a random forest on images downsampled to a single pixel results in 95% and 98% accuracies! (for the 4-category and 6-category versions, respectively)

And you can easily exceed 99.5% by adding more features to the forest, which is far above their DBN accuracy.

I have no idea how they were able to get an accuracy as low as 69% when they evaluated random forests.
"Literary fiction" is frequently simply a means of elevating the prestige of certain writing, by indicating that it is by/for literary elites.

In this case, the authors contrasted "literary fiction" with nonfiction, "popular fiction" and nothing. The literary fiction samples were drawn from a PEN/O Henry prize 2012 winners' anthology and the US National book awards finalists. The examples of popular fiction consisted of a Danielle Steele novel, "Gone Girl" by Gillian Flynn, and know knows what, although one of the authors mentioned "...genre fiction like adventure, romance and thrillers."

Who asked me? This is a web forum, the whole point is to say stuff, respond to stuff, and so on.

As for whether the original poster is or isn't making the world a better place for others, you're right, I don't know. After how they described their work in the sibling post to yours (something about making decision-making better), I'm still not sure how what they're doing is any good.

As for why I'm skeptical that they're getting it right (i.e. solving a problem people have) without going out and talking to people about it, my experience tells me that that's pretty tough to get right.

Customer feedback is gold, and putting on your "I only talk about work" blinders is a good way to get something done, but whether it's the right thing, well, how do you know?

Look, I get it, it's fun to geek out and try and "solve problems" and treat life as an engineering exercise, but if you want to do it right, don't just sit at home and think "this is the problem," meet people where they are, and see how your vision and ideas fit with that, and on and on and on.
> I agree that there's no particular reason to think that Heinlein is saying we'd all be better off if tomorrow we took away the franchise from everyone who hasn't served in the military.

Even if the novel was strictly prescriptive, it wouldn't be saying that: federal service wasn't exclusively, or even mostly, military; federal service included the military, but it also included pretty much everything that would be considered "civil service" positions in today's system, and those positions significantly outnumbered the military ones.
SharePoint and Sitecore: Together?
Money quote: "we believe that CAP has now reached the end of its usefulness"

From Conclusion:

In this paper we discussed several problems with the
CAP theorem: the definitions of consistency, availability and partition tolerance in the literature are somewhat
contradictory and counter-intuitive, and the distinction
that CAP draws between “strong” and “eventual” consistency
models is less clear than widely believed.

CAP has nevertheless been very influential in the
design of distributed data systems. It deserves credit
for catalyzing the exploration of the design space of
systems with weak consistency guarantees, e.g. in the
NoSQL movement. However, we believe that CAP has
now reached the end of its usefulness; we recommend
that it should be relegated to the history of distributed
systems, and no longer be used for justifying design decisions.

Even their official FAQ states that you won't be able to mine at a profit with their product:

"Can you make a profit with the 21 Bitcoin Computer after accounting for energy costs?

Yes, you can indeed make a profit with the 21 Bitcoin Computer. However, you would do so not by directly selling bitcoin, but by selling digital goods for bitcoin. That is, you are not going to get rich by immediately selling the bitcoin mined by the device for offline currency, but you can potentially do very well by selling digital goods and services to others for their bitcoin."

Devs: blow the whistle
This title is kind of click-bait - they aren't prohibiting operating systems, they _might_ be prohibiting installation of operating systems that are not approved on certain types of devices that allow software defined radio - that is, transceivers that can be tweaked easily by software.

That is not at all the same thing as banning an operating system.

This is already present insofar as hardware requirements in radios - radios cannot be permitted to listen on frequencies reserved for cell phones, and must not be restricted in such way as they can be easily modified to enable it (e.g., a header/jumper). This really just extends this requirement that it is non-trivial to enable illegal broadcasting or reception on software defined radios.

Now - insofar as if this should impact open source operating systems, we have a good question. I don't think it does that - my interpretation, potentially wrong of course, just as the article's could be wrong, is that you would have to restrict the actual firmware in question to a blob that communicates with the hardware in a secure way. This would prevent open/free components insofar as the actual driver, but would not permit the operating system itself from being installed. They mention this, but only at the end of the article.

I also doubt the impact of this for non software-defined/modular radio systems. I don't see a way this would really impact everyday wifi or non-modular systems in a way most people would care about. That isn't to say it isn't _bad_ but once again, it just seems super misleading and alarmist.

Whether or not the FCC should or shouldn't do this is a different question, but the link's title seems intentionally misleading.
Whats the standard world wide cost of electricity? It varies by well over 10:1. Also it varies over time. Its an arbitrage market for electricity, kind of. This is assuming a perfect efficient market, LOL.

Note that if you mine your own coins its very hard to track where they came from, what with there being no paper trail of you purchasing them from anyone. If you buy coins from someone then that someone can be strong armed by a .gov or .com into telling them who they sold coins to, assuming they don't have a direct data feed right to the DEA or whatever. So in the stereotypical bleating tabloid form of "buy weed online with BTC" if "they" have a list of BTC buyers as 0.001% of the population and give it to customs as a filter on packages coming in from Amsterdam... On the other hand if you're not on a list of BTC buyers because you mined your own... Of course WRT paranoia, being on a list of known custom ASIC owners is about as bad as being on a list of weed grow light purchasers, so I'm not sure this product fixes anything.
I'm totally with you. The CF-18 is pretty good for Arctic sovereignty and for maintaining our NORAD commitments, but absolutely terrible for peacekeeping & observation missions.

The average NYC taxi driver does not own a medallion. A couple years ago they traded hands for $1,000,000.00. Most of them are owned by companies which have many hundreds if not thousands of them.

These companies rent the medallion for 12 hour blocks to drivers and would charge them between $175-250 per block. Before Uber there were many more drivers than medallions and drivers would bid the price of renting the medallion for 12 hours up!

Drivers who worked full time and took a few weeks off would spend around $40,000.00/year on renting the medallion. A cab that was rented for 24 hours/day all year would easily generate $90,000.00/year for the owner of the medallion.

With Uber the companies that own the medallions (and more so those that took massive loans to acquire them) are the ones hurting. The drivers are just fine, if not better. And even taxi drivers I've spoken with like Uber because medallion owners are desperate for drivers now and are charging $100-$150/12 hours. They just want to get the cars out of the garage.

Uber drivers expenses that are different from cab drivers include a car mainly. Something that costs far less than the money they gave medallion owners and something they can write off big parts of on their taxes. And they can use it on their free time.
There are a few initiatives to end food waste. A lot of it is caused by supermarkets having exacting standards for produce. Food that doesn't meet those standards is sold off for other uses, or just wasted. There are a bunch of "ugly fruit" distribution outfits. Here are two, and a radio programme about other initiatives.

I think there are a few aspects to making delivery service economics work, marginal costs go down the more you can group deliveries and route better in areas. In other words, network effects.

1. Do I need it right this minute ( example pizza)

2. Is it purchased in advance or planned? Like weekly groceries

3. Are you just doing delivery, and that is your only revenue?

4. Will your earn a commission, transaction fee or add a markup? (i.e Instacart)

4. Are you going to follow an uber type model or integrated by hiring staff?

5. Can you group customers orders together and do delivery runs using optimization algorithms (tsp, vrp). Lowering your cost?

Here is an example (Using ZAR values / 10 for approx USD values):

Say you start a diaper delivery business. On average a parents will need it once a month. To make it simple we will assume 1 customer initially, and then scale up to 10. We will compare 2 scenerios.

Here is the example in Google Docs:

https://docs.google.com/spreadsheets/d/1fpdh9BPWJMqWXV-wWRl2...

Cost of diaper pack: $30

Avg cost of delivery per KM: $ 0.40

Distance to Deliver: 20 KM

Time to deliver & return to Hub: 1 Hour

Cost Per Hour for Driver (South Africa): $5

Delivery Fee: $3

Retail of Diaper with Margin: $35

Scenario 1, No Margin on Diapers, with 1 order

Total Cost: 30 + (20 * 0.4) + ( 1 * 5) = 43

Total Revenue: 30 + 3 = 33

Loss: $10

Scenario 1, No Margin on Diapers, with 10 orders

For simplicity: Driver will drive to furthest point, and each point is 1KM away in direction of the hub.

No change in distance driven. 1 Additional hour as more stops.

Total Cost: (30 * 10) + (0.4 * 20) + (5 * 2) = 318

Total Revenue: (30 * 10) + (0.4 * 20) + (10 *3) = 330

GP: $ 12

GP %: 3.64

Scenario 2, Margin on Diapers ($5), with 1 order

Total Cost: 30 + (20 * 0.4) + ( 1 * 5) = 43

Total Revenue: 35 + 3 = 38

Loss: $5

Scenario 2, Margin on Diapers, with 10 orders

For simplicity: Driver will drive to furthest point, and each point is 1KM away in direction of the hub.

No change in distance driven. 1 Additional hour as more stops.

Total Cost: (30 * 10) + (0.4 * 20) + (5 * 2) = 318

Total Revenue: (35 * 10) + (0.4 * 20) + (10 *3) = 380

GP: $ 62

GP %: 16.32 %

Ask HN: Books on understanding power consumption in electronic devices

So, "yes, you can make a profit, but only if it has nothing to do with the 21 Bitcoin Computer".
You have to admit, though, that there is nothing quite like the feeling of paying $7 for an Uber pool to go all the way across San Francisco, especially when it's surging 3.9x.
My take would be that Musk simply wouldn't sell. We know that they have spoken, and that Apple is an investor in the Gigafactory, so regardless, they'll be paying Tesla for iDevice batteries in the long run.

Competing against them on a car is a really interesting play though. Not sure what to make of it just yet.
The counter argument is that most new drugs are developed in the US (due to the large profit margins here) and that the UK, Canada & the EU are essentially free riding off the US in this area.

Not sure I completely buy this argument, but there it is.

You can make it difficult and very hard in practice through antenna and component design in the case of small internal radios - in radios with external antennas it becomes a great deal harder though, and in radios that are open for modifications it becomes even more difficult.

That being said though - this is meant to apply to software defined/modular radios - that is systems wherein the entire point is that it does what the software tells it instead of having hardwired components meant only to receive certain frequencies.

This doesn't match my experience at all. To me it seemed that throughout the 00s both consumers and small businesses were unwilling to pay anything for the cloud software, but tide has definitely turned. Now, all smart small companies I know don't blink an eye to spend hundreds of dollars per month for various cloud subscriptions and consumers are starting to pay for software both on mobile devices and cloud SaaS.
