Globalized capitalism has caused the largest reduction in poverty ever. If you had to be randomly born anywhere in the world, only getting to pick the date, you'd be smart to pick today if you wanted a decent shot at life.

Now, with regard to inequality in the US, that's mostly self inflicted. Moving production to cheaper areas lowers prices. It just so happens that the US chooses policies that increase inequality, rather than decrease it, like how education is funded.

The metric used to calculate market overvaluation is interesting but it has little value for predicting a stock market crash.
Let's take he last 3 major US crashes:

1987: this crash was caused by automated trading systems which could run wild in the absence of any prevention regulations such as circuit breakers

2000: the collapse of the dotcom bubble

2008: start of the financial crisis caused mainly by opaque credit default swaps and packaged subprime loans

Of those 3, only the dotcom bubble seems to be a bit related to the market overvaluation metric. And even right before the dotcom bubble crash there were plenty of economic guru's who argued that classic overvaluation metrics were not valid anymore because we were now in a 'new economy'.

The other two crashes were caused by black swans; occurrences that nobody was aware of and that were only understood afterwards. Most likely the next crash will be a black swan as well.
I'm aware, but it's not something nobody could give a crap about.
The thing is that no one is really motivated to make a complete tutorial on finding strategies because it's economically irrational. You're either giving away specific sources of alpha or you're empowering potential competitors. This is why it's virtually guaranteed that anyone selling courses that teach trading or related skills is a fraud - they have essentially no incentive to just ramp up their own trading capital instead.

The industry is also extremely secretive (necessarily so). You'll hardly ever find a good treatise on finding novel signals, but there are tutorials on algo trading in general with examples of production strategies that used to work which have been, as you say, traded away. For that purpose I'd recommend you start here: http://www.decal.org/file/2945
Looking at ROI(or any indicator alone) is possibly the worst way to spend your time, because it doesn't mean anything.

It's such a poor idea that you aren't even factoring the risks in. And can barely factor it, as it's bitcoin. What is the chance of this entirely thing breaking down tomorrow as people just give up believing on it? Big chance.

It's completely unusable. I can write a bash script which does more transactions than bitcoin on a calculator. The blockchain model it uses has no scale.

As soon as mining becomes more difficult and we hit close to 90% of the coins and use doesn't increase up(because usage didn't take off, like the prices), this is all worth 0.

Who has hit the jackpot is the one who sells before this ponzi scheme falls down and entered early enough.

Your volatility section seems to be a very poor indicator of a future crash in the manner you are using it. Volatility is not a predictor, but instead a descriptor. An analogy I think is the weather stick - Is this stick wet? Then it is raining. It is a very poor item to use in your context.

Further, sustained periods of low volatility often are sometimes indicators of complacency among investors and indicators of higher chances of bubbles. Sustained periods of low volatility are at times indicative of higher future risk of a market crash, not a low predictor. I think you need to re-evaluate how you use volatility.
I wouldn't be surprised if the trick is the resolution it is decoding to. Could test this by picking windows that are a related size to full screen.

How many users want their laptop to be less portable? Every quarter pound does make a difference in real world convenience.

You're already giving up performance if you choose a laptop over a desktop computer as your "tool", and probably using some form of cluster if you're doing any heavy computation.

Sometimes reading pros talking about how they need to do pro computing on their pro computer, you wonder whether they would get even more satisfaction from a bag of external batteries and lots of serious-looking accessories.

If they're running complex models somewhere off the grid, a large solar array and some car batteries would look even cooler!
You're misunderstanding what I mean by spec. A spec is made up of a list of requirements. This list of requirements can be considered constraints on processes, performance, features, limitations, whatever. Whatever makes sense in the world of the specifier.

For example, I can have a requirement that says: "The program shall generate a set of weekly time schedules that are maximally preferable, based upon each students' preferences, for all students at a given location while taking into account resource constraints re: room availability and teacher availability." Of course, this isn't specified to the level of detail I'd put in a real spec, but it serves as an example.

There's many ways to solve this requirement, i.e., there are many different programs that satisfy this spec.

There are two solutions that may stand out: (1) a brute-force approach, and (2) a convex optimization approach.

Since I've not explicitly defined a speed of execution requirement in this spec, then a brute-force approach may make sense... even if it runs for 5 days. In the real-world, you'd confirm this undefined assumption.

If instead my spec said this needs to complete within a day, then maybe the convex approach would make more sense. However, you'd first seek more definition in the spec, i.e., how many students are we generating schedules for? If it's only 10, maybe brute-force, if it's 20k, then convex.

So on and so forth.

Now, the interesting part comes when you create the end-to-end (E2E) and acceptance tests. These tests should be the first thing you write because they follow directly from the spec. They will stand up the program as if it's running in production and drive it as such to test whether it adheres to the spec.

Once all your E2E and acceptance tests are passing, and we've eatablished that your tests cover the spec completely, then we can mark the program as correct with respect to the spec.

There are many different software designs that satisfy a spec.

The software is not the spec.

The problem is that even things like "how many people touch this class" and "how many external teams do we work with" aren't simple at all. Some external teams are much easier to work with than others. Sometimes you want your whole team to intimately understand an area of your code. Making software is an intensely human process, which is why managing software teams is almost entirely about considering the people on your team, and what makes each of them different.
Full screen video could skip most of the other composition that needs to happen, though. So while the video decoding itself may not be any different, it certainly won't have to go through drawing everything else that would otherwise be on the screen.

You're misinterpreting what people mean by "inefficient" in this context.

The bitcoin mining ASICs are extremely efficient at mining bitcoins. You can't mine them with an old GPU and expect to make back more money than you spent on electricity.

But the choice to mine bitcoins at all is (arguably) an inefficient use of resources that could have been used for pretty much anything else. There's no shortage of useful problems to be worked on by supercomputers and the world would be better off if we did that instead of mining cryptocurrencies. But the economic incentives aren't there.

EDIT: Reading your comment again, I think I was a bit quick on the "you're wrong" here. ISo to clarify, I do agree that inefficiency is at the core of the bitcoin mining ecosystem, but it's all about the "we have to spend a bunch of energy that could've done a lot of other things" inefficiency, not an individual "we can use old hardware for this" sort.

> market valuation expressed as market cap as % of GDP

This metric makes little sense for this use case. Consider two countries. They are identical in every way except in Country A 90% of the companies are publicly-traded while in Country B 10% are. Country A will have a market cap to GDP 9x Country B's. Does that mean Country A is 9 times overvalued relative to Country B?

The objection works in-country, too. Saudi Aramco is going public in New York or London [1]. This will lift one of those market's aggregate capitalisation by up to $1 trillion. Does this mean that market will necessarily become overpriced?

The answer to both question is of course not. Market cap to GDP tells you the degree to which a country has developed public markets. Not anything interesting about the levels in those markets.

I get what he's saying. I believe the debt I acquired in college really messed up my life.

But there's also the fact that college is now free in Germany, and that offer is open to Americans. I actively tried to persuade a family member to at least consider Germany as an option. After all, what could be better? Free degree, travel Europe on holidays, no drinking age issues.

She didn't consider it. She's going to a college nobody has ever heard of in the US and spending $45K annually for the privilege. At least I tried :-/

Hey! I really like my cheap produce.
If everything goes well, then this change will not have been particularly noteworthy... it is going into Unstable now, and if it causes problems then that is exactly how it works.

Packages are not promoted into (out of?) testing unless they don't have open issues reported against them. If this concerns you, then the right thing to do is to file an issue. Keep it open long enough and this won't make it into the next stable release.
Each step up gets more cache size, turbo boost, hyperthreading, internal graphics, cpu features, and power options, depending. Also, i3/i5/i7 isn't the only thing to consider - look at the product suffix (U/Y/T/Q/H/K) that adds or removes features to that model.

Compare the i3-6100U to the i7-6500U - both skylake ultra-low-power CPUs [1]. The i7 has about 30% faster effective clock speed (plus the turbo boost, which gives a small jump in clock speed when necessary, which can reduce battery usage) and 25% more cache. But another i7 model, the i7-6550U, has better graphics, even faster turbo boost, and a bunch of "Pro" Intel features that neither of the others have. Move up to the i7-6700HQ and now you have two additional cores, incredibly faster performance, even more cache, and higher limits up the wazoo.

Of course, newer microarchitectures may have have more optimal code paths, slightly higher clocks, smaller dies, better graphics, and use less power. So an i5-7200U may have better performance, similar features, and use less power than an i7-6500U [2].

I'm not saying the government subsidies are wrong, but a counter case might be what if the government subsidized scientifc GPU's at the turn of the century over gaming GPU's? Would gaming have grown as big as it is without modern GPU's targeted at gaming? Would we have gotten such cheap GPU compute power without the massive investment in gaming? Would the government subsidy have ended up hurting long term advancement in GPU's?

The volatility index, or VIX, has become a popular measurement to reference in the context of predicting the market over the past couple years.

The problem is that it does not seem to have any real predictive power and I have yet to see any shred of evidence that the VIX has been shown to have predictive power over the future value of the stock market.

It is calculated from past price variance and is used in calculating the theoretical price of options, but that is it.

Does anyone have any evidence the VIX has value?
He did it internally. He didn't leak very much publicly other than broad strokes about what was happening. He 'leaked' internally to the DoD IG. The response from the FBI/NSA was essentially to punish them and what amounts to a public witch hunt at the hands of the FBI. This response was what started the trend of much more public whistle blowing because it became clear if you went through the official routes you would be persecuted and your life made miserable, even if they could not land you in jail.

All of this under the banner of state secrets justifying these actions. Whereas in any corporation or visible branch of government the waste would have been a scandal. In the NSA the use of state secrets means power concentrates and individual employees have little recourse (Snowden, etc.).

Hi there,

Would you recommend AWS over MS Azure to setup a virtual machine for academic purposes? Or any other tool you may know specially if it is cheap. In order to spend some death-time learning something.

Also, do you know any web based ssh tool (reliable in terms of privacy) to access the above mentioned virtual machine Or any other tool for this matter?

Thanks.

The author is clearly mistaken. There are several things that are possible in the physical world yet illegal, e.g. forging signatures, breaking doors open, breaking into parked car, sending spam emails etc. Specifying reindentification as illegal is a great step since it let's legal machinery to do its job.

The reality of data privacy is that it's impossible to guarantee anonymity while keeping data useful.

Reindentification ban enshrine coherent guidelines into the law. It's a good step forward.

I am saying this as a researcher who has signed several agreements with US government agencies which had reindentification ban clause and penalty of felony offense if found violated.

"occurrences that nobody was aware of and that were only understood afterwards"

Umm, I'm no genius but I was managing my mother's money at the time of the 2008 crash. It was very obvious to me that there was going to be a crash, I pulled out of the market in late 2006 and didn't lose a dime in the crash.

I think the better statement is "The 2008 crash was obvious but many people were in denial".

Again, I'm not a financial wizard, I could just see the writing on the wall on that one, everyone was getting approved for houses they couldn't afford, you just knew that was not going to end well.

No, I haven't done any multi-GPU or multi-node work with PyTorch... at least not yet. So far, I've used PyTorch only for quick-turnaround tinkering and experimentation, and for building prototypes, typically with small datasets or smaller subsets of larger datasets.

For real-world workloads, I, along with my work colleagues, currently use TensorFlow, which has good performance, large community infrastructure, and fantastic tooling around it.
If an idea shows promise in PyTorch, our next step is usually to implement it in TensorFlow with more data. But we do a lot of experimental tinkering in TensorFlow too. It depends on the learning task at hand.

Note that this version of PyTorch is the first one to support distributed workloads such as multi-node training.

It definitely looks gimmicky, but damned if it's not convenient when you do need it.
You are basically limiting "produce" to mean produce basic subsistence items like food, clothing, and shelter. Yes, of course the fraction of people that need to work to produce those things will decrease with automation--that's been happening for most of human history, and has been happening a lot faster since the Industrial Revolution. In the US in the late 19th century, IIRC, something like 19 out of 20 people worked on farms. Now it's about 1 in 20.

But there are two things that can happen with the surplus capacity available. One is for people to, as you say, "branch out into other things"--produce things other than food, clothing, and shelter. There is a basically limitless demand for goods and services, and once one of them gets automated, people just find other things to demand that aren't automated yet. In other words, just as you say, you have people doing things that improve the lives of everyone.

The other thing that can happen with the surplus capacity available is that it gets wasted. People who find they don't need to work to make a living, do nothing that improves the lives of anyone, including their own. The best case of this is that they sit all day watching soap operas, or something like that. The worst case is that they start doing things that worsen the lives of everyone, like committing crimes.

The question is, which of the two possibilities above is the default outcome of mass automation, if mass automation actually does remove the need for the underclass to work at basic subsistence production? You seem to think it will be #1; but my money is on #2. If we want #1 to happen (and I certainly agree that #1 is vastly preferable to #2), we are going to have to give people an incentive to produce things that improve people's lives. I don't think most people will do it without such an incentive, and historically the only incentive we know works is the need to earn a living.
Our RN project is quite early in development, so it's hard to say, but so far we like it quite a bit. We're a small shop, so the thought of hiring out a dedicated Java and ObjC developer was really, really hard. RN made this whole project much more approachable, and is proving invaluable.

Again though, these are just early impressions.
