I live in Nairobi and PAYG until you own it ($35 deposit then $0.45 per day for a year) - this is mainly targeting rural off-grid (70% of East Africa) - where they spend $200 on Kerosine p.a

Their main challenge is repayment - some days people forget to repay or have competing financial priorities - I think they give grace periods before remotely turning off the power.
I was going to say "also, isn't the Swedish word for 'quick' snabb?" But then Wiktionary told me that there is, in fact, also a word kvick with a similar meaning.

Extra bonus: it turns out that quick/kvick is cognate with Italian/Spanish/Portuguese vivo 'alive' (which makes the older sense in "the quick and the dead" make more sense, too!).
It can have huge consequences for us down the line. For example when Theodore Roosevelt decided to preserve national parks, it wasn't as big of a benefit to the public, mainly recreation. But in Yellowstone's hot springs a bacteria was discovered which now helps major biological processes through a technique called PCR.

Investments in science can have huge payoffs.
True, but the theory behind MIMO and DIDO (i.e. pCell) is the same. The challenge is overcoming the synchronization and timing problems introduced by having antennas situated miles apart and connected over the Internet, rather than a few centimeters apart on the same circuit board. People had similar concerns about cloud gaming, but OnLive (which, note, also came from Rearden Labs) and Gaikai proved it could be done surprisingly well. Now that I think about it, Rearden may already have gathered some highly relevant expertise from their experience with OnLive.

Also, Rearden has been claiming for some time now that they have working demos. I doubt they're making that up. I fear, however, that Artemis may meet a similar fate as OnLive: a technological marvel that unfortunately fails in the market.
The butterfly effect is good for millions of years--maybe, but giving Hitler a cold in 1925 definitely would not have altered his trajectory in the least (blah blah blah goodwins law blah blah blah) there's just so many other things at work that most small things do very little to decide the success or failure of a company -- despite all the stories people love to tell about fedex's last $25,000, if the founder had gambled the money away instead of quadrupling it he woulda just found an investor or bank willing to back him and fedex would be in the same place it is today.
That's a tough one because not everyone reacts to a drug in the same way. Perhaps for some people psychedelic compounds and drugs are beneficial, but for others they are not. Regardless, it is just stupid to insinuate that LSD will make you wealthy beyond imagination.
If there are libraries that silently accept an unsigned JWT with alg:none, even when they are provided a secret key to verify, that's a serious CVE right there...

If a secret or public key is passed to the verify function, the function MUST fail if no signature is actually present in the token. E.g. on node-jwt; [1]

if (parts[2].trim() === '' && secretOrPublicKey){
return done(new JsonWebTokenError('jwt signature is required'));
}

As another example, in the C# library, as long as 'RequireSignedTokens' is true, it will ensure the signature can't be stripped. [2] I'd say that's poor design to allow specifying a key and then ignoring it silently if 'RequireSignedTokens' is false, even if it is true by default, because the combination of 'RequireSignedTokens' = false, and a non-null key, is invalid.

It's actually entirely possible to do some "checking of your answer" for p-values, as well. As you mentioned, for practical math, you can often validate your answer against the initial assumptions. This is true for statistical testing too, as it typically relies on many theoretical assumptions. So what you can do in practice is propose a different set of assumptions, perform the hypothesis test in a manner that follows those new assumptions, and see if you obtain a similar result. Typically, for any given hypothesis that you want to test, there are several possible methods for performing that test, so you can redo your test many times. This is one type of robustness checking, which includes many other things as well (e.g. running your test over subsamples or resamples of the data, checking for sensitivity to outliers, etc). Good statisticians generally like to do lots and lots of robustness checking.

No there's a 5% chance the null hypothesis is correct. the probability your theory is correct is unknowable.

I think what this journal doing is probably a good thing, but only as the lesser of several evils. The truth is something more like... it is easier for soft sciences to abuse frequentist statistics than bayesian. Both have merit, it cannot be argued, but it is simply easier to produce meaningless conclusions with frequentist statistics done wrong.

This situation is so bad that it merits banning frequentist for this journal and I think that's reasonable. This doesn't mean that every journal in every field should, but perhaps it will be a useful temporary measure to improve quality.

This is really fantastic! It's doing something really amazing and important in the realm of architecture and construction that's much needed.

It's weather-agnostic - (certain construction work you just can't do in winter). Bottlenecks are easily controlled: No questions about worrying about different trades (say, the structural steel work, etc) being slow and pushing all other aspects of the entire project behind. It's more predictable, since you have very clear quantifiable markers of progress (what % of units are completely finished?) It cuts down on the costly / cumbersome process of using a hoist during construction, which is expensive and timely since you have to hire specialized labor and get a permit to close off the street.

To use a programming analogy, it's effectively a kind of parallelization or non-blocking i/o, since you can track progress in a reliable, controlled setting, stagger your work, and have many different trades working at once, on different aspects. (Electrician behind schedule on half of the units? You can still have the plumbing crew work on the finished half while bringing more electricians on board.)

Present-day construction is highly linear, mostly single-threaded and filled with bottlenecks everywhere, since it's both a logistical and financial disincentive to hire a trade to come in to do work if there's not enough work for them to do. The contractor pads the schedule to make sure that previous work will be ready for future work. As a result, construction times are longer, less predictable, etc.

Granted, this isn't totally new, but it's really important that prefabrication is getting more visibility and is understood to be the architectural game-changer that it will be in the future.

> I am a big fan of Michael Pollan, and his main argument is that even nutritionists and doctors, people who dedicate thier lives to studying nutrition, can't answer lots of the more complex questions

One fantastic thing about a versioned product like Soylent is that it actually may make it possible to determine those answers empirically. Given the existence of a simple standardized diet that people are willing to eat exclusively outside of a laboratory setting, you could pay a bunch of volunteers to eat soylent you provide which either has or hasn't been modified to include different amounts of vitamins, different amounts of carbs or whatever.

> I'm not willing to prove that theory wrong using my own body.

Fortunately you can't stop other people from experimenting in just that way. The world is full of people who eat odd restricted diets and live reasonably long, healthy lives. There's no reason to let the best be the enemy of the good. Start with something that's just barely "good enough" and iterate on it until you really have something.
Tree structure query with PostgreSQL
You're absolutely correct that Bayesian approaches are not magical and do not suddenly supply you with vastly more information than frequentist approaches (particularly when you have a really poor prior, in which case the Bayesian approach will be similarly poor). Bayesian statistics is certainly very popular right now, but it should not be looked at as some sort of panacea for all statistical problems.

However, I would say that Bayesian approaches do have a big advantage in terms of helping with the interpretation problems that plague frequentist significance testing. Namely, as the OP article points out, Bayesian approaches reformulate the testing question in a way that is more intuitive, i.e. "what is the probability of the hypothesis given both the prior probability and the new data?". So yes, Bayesian methods surely do not fix everything, but since interpretation of statistics is such a major concern, they can be quite beneficial.
Not quite. The 5% represents the chance that if the null hypothesis is true, you would draw data at least as extreme as the data you just saw in a repeated experiment.

Computing the probability that the data came from the theory stated in the null hypothesis would require a (Baysian) prior.

Also, Tloewald's reply is completely and inexorably wrong. Tloewald seems to want a Bayesian answer, which frequentist statistics can't give you.
Theres no denying the importance of luck in the outlier outcomes. Thats why a fundamental heuristic of any startup idea you work on should be: "would i be proud i worked on this problem even if i don't get an outlier outcome?" If you can't say 'yes' to that, you probably won't have the fire to overcome the unpredictable obstacles that will fight you every inch of the way.

Ultimately, that means shifting from a 'risk calculating' mindset to an 'exposure mindset.' Instead of 'what are my chances of success', 'am I cool with potentially spending years of my life on this problem regardless of outcome'? The exposure perspective is the basis for 'antifragility' and honestly makes life quite a bit easier and more satisfying to live.

Hey everyone! This is a project I've been working on for the past year. The goal is to create a platform where users can discuss both local and global content. The main action is in filtering posts by Location and Channel. See what you think! I would really appreciate any feedback/suggestions.
(Googler here)

It's a platform feature, so it's open source, but there's always a delay between the announcement and the time the code hits the public repositories. It'll be there before too much longer.
The main issue I've noticed is that compared to many other calculations, you just have no idea if your result is correct. You can make wrong assumptions, wrong calculation, apply wrong methods, but in the end you get a number... and that's it.

The same is true in Bayesian statistics, and even simple formal reasoning with no statistics in sight. If you make wrong assumptions, you'll get the wrong result.

The only thing you can expect statistics to do is help you change your opinion about the relative merits of opposing theories. If both your opposing theories are wrong, you will still be equally wrong.

The true flaw with frequentist statistics is that it goes out of it's way to hide this fact from you. In contrast, Bayesian stats forces you to explicitly choose a prior, enumerate your assumptions, and accept that your conclusion is based on these things.
Sorry, but the only ignorance here is your own. You assumed that "storing into an array" means that the array index is the only thing relevant for locating a record. But the fact that you're talking about inserts/deletes means that the array index of a particular element is mutable and therefore insufficient for uniquely locating a record. Which means you must perform some type of search to retrieve a particular item. Your O(1) getitem is nonsense.

Yes, you can say "give me the 5th element of this array" but the discussion was about maps/dictionaries, where you're more often going to say "give me item foo that was inserted before".

When folks like you post while obviously not paying attention, yes, you elicit a dismissive response.
Good work. And yes, another failed experiment.

Two complaints:

1) When I go to the front page (https://www.google.com/flights/), everything from and including the 'return/one way/multi stop' row down is fixed-width at about 650px even when my window is far larger. This sort of fixes itself once I start selecting cities, but is randomly narrower than the auto-sizing search bar + other stuff above it. I'm on Win7 x64 / FF 36.0.

2) Please localise currencies. You auto-detect me in Brisbane, Australia. If I pick a flight to Sydney on AU carriers, I don't care about prices in USD. You either convert it to USD in the first place (or just assume 1AUD=1USD) but don't when you display it to me.

Any omnidirectional microwave/RF network technology will have a short enough range that the signal propagation time is negligible for the purposes of human-perceived latency. This is a consequence of the need for cells to be small enough that they are only serving a manageable number of users. (Directional links like microwave backbones and backhaul can have latency worth caring about.)

Any latency you perceive comes from your packets sitting in a buffer waiting for their turn to be transmitted or waiting to be re-transmitted after a collision. The problem of queue management for wired networks has only had a satisfactory solution for a few years. When you throw in things like collisions due to the shared medium and interference from other users of the spectrum (less of a problem for cellular than WiFi), transmission rate and power selection covering multiple orders of magnitude, interference that can be problematic for some users but undetectable for users elsewhere in the cell, and the almost complete unwillingness of the hardware vendors to sell anything hackable enough to do research with, it's clear that wireless will continue to suck for the foreseeable future. However, a lot of these problems get a lot easier when you're working at a frequency that can never reach from the inside of your house to the inside of the neighbor's house.

You're still taking the prior probability into account when trying to figure out the truth, you're just not putting a number on it.

This is a danger sign - you are doing the same things the Bayesians do, just informally, less explicitly, and probably incorrectly.

The fact is that to make a good decision, eventually you need to compute a single number. This is an elementary fact of topology:

https://www.chrisstucchio.com/blog/2014/topology_of_decision...

That number will be based on some unproveable assumptions. That's a fact of Godel's incompleteness theorem, if nothing else. So given this, why is it "dubious" to make those assumptions explicit and obvious?
Claiming Obama is only a little better than Bush is a little silly.

We have obamacare; for all it's flaws, we've both massively reduced the number of uninsured in the United States and slowed the growth of health costs. It's a huge win, and while I would have loved single payer -- hmos and all health insurers are nothing but parasites -- the fact is he didn't have the votes in the Senate and Obama did as well as possible. I'm pretty confident that in the 20 year timeframe we'll have something pretty close to single payer, whether it's true single payer or strong caps on how much resources insurers can suck. Obamacare is also a massive gift to anyone who would like to start a company, both for the original founders and for early employees.

We have many fewer troops in Iraq and Afghanistan.

While I wish Obama were much better, those are two big differences from Bush.
