What about polluting the blockchain?

We will move this protocol to a Bitcoin sidechain designed specifically for public data as soon as the technology for building sidechains becomes available.

In the meantime we've been using this protocol while prototyping other protocols that rely on storing metadata in the Bitcoin blockchain.

> The thing is, we already know that the brain influences the gut, but this doesn't seem to be mentioned. All these hand-wavy press releases seem to be saying it's a mystery why IBS is linked to anxiety and depression, and yet there is very good evidence that the HPA axis significantly influences gut motility, absorption and bacteria.

Do you have a recommendation for further reading on this? (Specifically, the brain influincing the gut, not vice versa.)

Purely anecdotal: I have a lot of digestion problems, but it is starting to look like I do better when I am able to maintain a non-depressed, non-anxious state of mind over a period of weeks.

>I think it's kinda bullshit that there seems to be no limit on the information that the government, Facebook et. al. can gather on me, but somehow I can't be trusted with information about my own genetic code unless it's been vetted by the FDA.

All the FDA did was prevent them from making unsubstantiated medical claims from the results of their test, in the same way that they would for, say, a new pharmaceutical. 23&Me could always go and perform the necessary clinical trials and submit the evidence to prove their results to the FDA. FDA is doing what the FDA was designed to do. What's the problem?

>Yet supplements and diet pills can make all kinds of bogus claims with impunity.

That's because the supplement lobby launched a huge political campaign and got congress to change the law barring the FDA from investigating supplements, after the FDA tried to regulate them.
I had an concept once for a decentralized reddit-like that used NNTP to distribute content and an inflationary cryptocurrency to store karma. The idea was that karma is only valuable while the thing that is generating it is relevant. If you wait long enough, your "karma-coins" will be, essentially, worthless. The deflation of your coins is dependent on your average net-worth over some period of time and the state of the global economy. (Maybe?)

I got busy with work, so I never got into the implementation stage, but it is on my backlog. Hopefully I get to it some day.

But taxation can itself become addiction. When a government earns enough from gambling it becomes a necessity. Rather than dissuade, the government starts promoting the vice (ie state lottos). Some say this has happened with smoking, that countries like Canada and the UK now take in more through taxing cigs than they spend on treating smoke-related disease. That's the danger of vice.

The speed and instant gratification of using a search engine to find information online is becoming a problem for me. I'm only going to conduct information searches at a public library from now on.

Almost everything we used to physically undertake can now be achieved online, with perhaps the exception of physical stimulation by a third party, and that's probably not too far away. Society needs to realise that if there's gambling at bookmakers on the high street, there's going to be gambling online. As another poster has suggested, the US should consider legalising and then regulating the activity, not continuing with prohibition.

Of course there will be people who suffer addiction and financial issues due to online gambling problems. In the same way, there are people who can't stop surfing porn, who can't stop messaging/texting/updating Facebook while driving, who basically now never leave the house because they're on their arse surfing the Net at home. It's not going to stop.

There are many, many positive aspects to modern connectivity. It is how society deals with the negative aspects of online culture that is important.

Thanks for replying.

Most compressed air systems attempt to pull as much moisture out of the air as possible to prevent corrosion, but your solution to the heat problem means actively making the air and interior even more wet. This wouldn't be a problem in the short term, but your product is meant to be used over a very long period (~20 years); how are you approaching the issue with corrosion?
And it's weird how people bring up the idea of an elevator to the moon more often than they bring up putting cars to run on rails. They could be 100% self-driving that way, and accidents would probably be nil.

Yes. Centralisation is just much more efficient in this case. (and maybe in all cases?)

I think it's sad that so much of this is driven by SEO -- a desire to satisfy an algorithm -- rather than to make good quality human readable content in its own right. In a desire to get on the front page of Google so much useless content is being created, and the content itself is tainted by the inclusion of keywords. This is because, as the article mentions, Google's algorithm can't tell a quality article from one that isn't.
And it's not even that bad in principle. In a more perfect world you want to have is freedom of speech and an organization like S.H.I.E.L.D. which secretly scoops all communication to protect the public from greater threats. Unfortunately, what we got instead is a kind of Hydra that lacks ambition for world domination.

Sure, but the salary they draw from the charity will be taxed. It may be taxed at a slightly lower rate than capital gains if they don't earn much, but not extremely so.

Or he/she was a pro and left the casings and a chunk of the gun on purpose to cast doubt on the idea that he/she was a pro.

Once you go to the level of "this was state sponsored in some way" all normal investigation and inference goes out the window. State sponsored folks would know how normal police investigations are conducted and have plenty of ways to counter them.

Why a particular state would want these people dead is another matter entirely though.
Dentures and implants are more about functioning teeth than "perfect" teeth. Poor folks can live with unsightly teeth but they can't subsist entirely on jello. Patients with unlimited dental budgets will be aggressively sold on root canals and veneers by every dentist they see. Most dentists don't want to make dentures or place implants, so they price themselves out of that market.

However, some dentists make inexpensive dentures, and poor patients will drive hundreds of miles to see those dentists. Because such dentists make 20x as many dentures as their higher-priced colleagues, they're much better at it. In this case price is negatively correlated with quality. The implant market isn't quite like that yet, but it's going in that direction.
From the article: "In the case of the spinal cord injury data, Ayasdi’s TDA-driven approach mostly confirmed what researchers already knew: The drugs didn’t work."

How this "Ayasdi" company's analysis probably works (based on "Topology based data analysis identifies a subgroup of breast cancers with a unique mutational profile and excellent survival" and the original "Mapper" paper "Topological Methods for the Analysis of High Dimensional
Data Sets and 3D Object Recognition"): They take point cloud data and connect each point with its neighbors (the distance metric that is used is probably domain-specific) to build a proximity graph that approximates a simplicial complex. As input to their algorithm, they also have one or more scalar functions defined on the point cloud data that contain information which is relative to the problem at hand. For example, each point could be a gene, and maybe the scalar function value at that gene could be probability of association with some disease, and the distance between two genes might be the Levenshtein distance between their genetic codes.

With data in this form, they approximate the Reeb graph of one of the scalar functions, which is a sort of "data skeleton." They can do potentially interesting/useful things with it.

The approximation of the Reeb graph reveals zero-cycles (connected components of the simplicial complex) and some one-cycles (handles/tunnels in the graph, sort of like holes in a donut). This "skeleton" of the data allows them to do a variety of things, such as segment the data into components that are (approximately) topologically "simple" (they do not contain any 1-cycles), identify local maxima/minima, find saddle points where forks in the data merge together, and locate "essential saddles" which constitute the high points and low points of handles/tunnels. They can also remove "topological noise", which helps them to separate spurious topological thingies from features that might be important.

Their technique doesn't necessarily recover "true" topological information since a lot of what they do is approximate. There are actually more accurate techniques (e.g., simplicial homology, or fast Reeb graph algorithms) for getting an exact answer, albeit with potentially higher computational cost.

Topological data analysis is a big field, and this Ayasdi company appears to mainly use this one approach (but I could be wrong). I think they are trying to lay claim to the term "topological data analysis" and get people with money excited about it.
But the goal isn't efficiency - it's permanence.
Here's to hoping that you're just trolling. Your reply injects very specific racial and socio-economic biases as if they were already assumed and understood. Which, in this context, is basically racism.
This is the breakthrough:
In the case of the spinal cord injury data, Ayasdi’s TDA-driven approach mostly confirmed what researchers already knew: The drugs didn’t work. But the discovery of high blood pressure’s detrimental effects on long-term recovery has immediate implications for human patients, namely whether the use of hypertension drugs immediately after their injuries and before surgery could improve outcomes,
Ask HN: Will the SaaS model work for downloadable software?
Recently downloadable software companies like adobe and jetbrains have had a major customer backlash when they changed their pricing model to SaaS.

Do you think this is the future for all downloadable software or do you see this as a wrong move?

Are there any rules that help decide whether a Saas pricing model would work for a specific piece of software?
Foundations of course, can invest in for profit companies, whose goal it is to generate returns for the foundation.

A year ago i canceled cable TV subscription in Germany because i had most important channels anyhow via DVB-T. I had internet subscription for years with them and was satisfied so this had to be kept working.

Knowing a bit about how these cable networks work inside the building i was curious to see how they will implement this. I thought they might have a filter for all those just having internet subscription but this could only work with certain types of wiring inside the building and also depends on access to the equipment which is not always available to them.

Then i thought they might replace the wall socket either with some filter build in or just missing plug for the TV. But again this is only possible when they are allowed to access the equipment or maintain their own. Also this seemed to be rather expensive. The basic cable package doesn't cost that much and the provider outsources all kinds of installation related tasks. I would guess using this rather weak method would pay for some years of Basic TV package subscription.

Long story short, i waited several months and nothing happened. I still watch cable TV like i did before. But as is said, its possible that they are able to cut you off on some kind of installations. But its also questionable if the cost of this would be adequate.
Much for efficient, yes. But also much less decentralized, which is the point of this presentation.

That's not a good comparison - when Congress was set up the massive debate between the founders was over how to do representation. Which is why we have a bicameral legislature. When doing population comparisons, you should use the numbers from the House of Representatives (population based, which is why we have a 10 year census) instead of the Senate (2 per state, regardless of size).

I always considered the "crypto nerd's imagination" panel in the comic to be that the NSA have computational and/or cryptanalysis breakthroughs and super computers so far ahead of anyone else that they can crack almost anything.

I have friends who are very into this and it is something I simply cannot understand. No one I know has ever won money in the long run, they all lose. Usually when you ask "How much have you won?" they will tell you "Oh, about $x" but what they mean is not how much they are up net in the long haul. They will get on a streak and keep betting until they are up about 1000 or so, then start losing and keep betting until they have to put more money in the account. That doesn't count as a loss to them though, they add that 1000 to the total. These people are both in denial to themselves and others about how much they have lost, its like they don't understand the concept that when you lose the money you won, you aren't "winning" at all. There are some of them who understand that they are losing but they don't care, they say that they bet because it makes sports more interesting, and these people seem to have the habit in a reasonable amount of control. The other's don't seem to realize it's never going to be "the next bet" that lets them cash out.

But many states that ban gambling already have lotteries, so the two aren't as clearly linked as you think. Plus, stating the governments 'promote the vice' is a big stretch, governments don't promote the lotteries, the companies that run them do.

As for taxation on cigarettes, why should all the money go to treating smokers? It's fantastic that there is extra cash to go to other causes. You cite the UK government but you'd be hard-pressed to find evidence that they are promoting smoking, indeed the laws on smoking advertising keep getting tougher and tougher.

I suspect that you've just got an axe to grind against governments in general.

My first reaction was that funding artists, musicians, and business is probably not the greatest charitable good that can be done with his money... but then I reconsidered -- It might not be the greatest good, but it is more good than leaving the money in the bank.

2 minutes is way too long. My mouse stops working in the middle of an intense flow? When I'm rushing a piece of work for a deadline? When I'm in the middle of a game? Stopping for 10 seconds to scramble to get the cable in is fine. Sitting on my hands for 2 minutes waiting for the thing to charge, during which my machine is essentially unusable is totally unacceptable.

Why not put the port on the front (like Logitech does)? It can still be placed aesthetically - the front side of a mouse is something you never ever see.

This way we could say the entire universe is just a big chemical reaction. It wouldn't even be an incorrect view. It just wouldn't be useful for anything.

This is the real value of models and concepts we use - not their grand philosophical sense, but how useful they are. We set up boundaries between creatures, define concepts like life and death because they allow us to understand and predict the world better. It's usually more useful to treat two creatures as two creatures instead of one, but sometimes it's the reverse - for instance, it's often more useful to treat an entire colony of ants as a single being, individual ants becoming just cells / organelles.
