duckingtest··on Austria: The up-and-coming early-stage investment capital of europe
That's not an inherent risk of being young, that's a risk from doing these things. In fact these activities are safer while young, if only due to a better reaction time.
duckingtest··on Austria: The up-and-coming early-stage investment capital of europe
>Your argument is flawed in that it reduces the talent competition to just one factor: the tax rate.

In Europe, London and Berlin have much better access to capital and bigger startup scene; these things have to happen, you can't legislate them. Tax rate and business environment is the only thing that can be changed by at will and perhaps make the rest happen.

>It ignores factors such as cost of living (which is, at least, equally important), and quality of life.

Where Austria wins how? Don't cite average statistics: how is life in Austria better than the rest for someone earning ~€10k gross a month? Note that's always connected with the tax rate.

Want really cheap living? Go to Bucharest, great internet is a bonus, also many local developers, 16% linear tax. Want great quality of life? A waterfront property in Spain, Canarias, or even Bali, some guys work like that.

People may stay if it's ok, but to make them move to you, you need to be the BEST at some linear combination of all important factors.

>Nonsense. Young people need healthcare as well, be it for something trivial as flu medication or a visit to the dentist

Why do you need insurance for that? Just go and pay out of pocket. Btw there's no such thing as flu medication. The only medication you may need is something to decrease temperature, but that's OTC.

>or something far more serious.

Which is very unlikely if you are young. Even then, outside of US health care isn't that expensive.

>The employer, however, had to pay the salary of 120.000,- to the employee and about 22% of the salary to the state and social insurance.

That's just accounting fiction. You could as well make it so that the employer pays everything and proclaim there's zero tax. The employee has to make his entire cost (and more).

>Apart from that, 120.000,- EUR for a developer in Vienna seems a bit too much. I would expect something between 40.000 - 65.000 on average

Well yes, there's no financial reason for someone capable of earning more to be in Austria. Which means there are no companies that could use these people to their full potential. In other words brain drain.

Not like high tax is an exclusively Austrian problem. The only country in Europe with sane taxes is Switzerland.

50% income tax above €51k. Hardly progressive. So let's say you earn €120k gross as a developer. Using this calculator [0] - input 8571 monthly because of some weird bonuses - it turns out you get €73344,69. That's not all - the company also has to pay 21.7% as a social tax. So in total, you get 50% of what you earn. But wait, there's also 20% vat! Which makes the total tax rate 58.14%.

There's NO way a startup in Austria is going to compete for talent with the rest of the world. Maybe Austria works for official company residency but not actual work.

>the benefits far outweigh the costs

Yes there are benefits and costs. It costs those that are highly productive and benefits the rest.

>or excellent healthcare.

which young people don't need, and by the time they are going to need it, the demographic situation (in the whole Europe) is going to be horrible and benefits are going to get seriously downsized.

duckingtest··on Bulgaria Passes a Law Requiring Open Source
What happens is they pocket $295k and spend $5k on an actual project. In Poland a company got ~$150k to make a system to collect and count votes for local elections, it failed spectacularly. It turned out they employed one 23 year old CS student to make everything over about a half year. No public salary data, but I bet they paid her something like $800/month. The saddest thing is she got most of the blame for failure, if you google her name it's the only thing that comes out.

>However the above method would categorize this dev as "objectively less productive", which seems counter-intuitive...

It wouldn't, it purports to explain the differences in local salaries, or more precisely salaries paid by local entities to on-site developers.

It's true I didn't specify that explicitly in the first comment, along with definition of productivity, so your reading of it was a reasonable understanding. It's a good thing you helped me clarify the intended meaning.

One assumption is that foreign demand (for non-local use) for local on-site developers is small enough to not change the workforce demand significantly. So it won't work for India or other common offshore destination, but it seems to explain pay differences between USA and Spain, Norway and Switzerland reasonably.

>For example a dairy farmer in Switzerland earns more than one in Poland because people pay more for milk products in Switzerland compared to Poland.

A Swiss farmer is much more productive when measured in currency units, but probably not that much in milk volume.

However as we are talking about salary differences it's money that matters.

>So why would the GDP per capita of their country be a useful tool in deciding who to hire?

Why would it be? In this conceptual model the ability of a developer is how much he multiplies the output of whatever he's working on, but his productivity is the absolute value of added output. How could it be counted otherwise, in what? Lines of code?

If productivity didn't depend on location immigration wouldn't exist.

>Stop using the GDP per capita of an entire country as a proxy for software developer productivity. It's frankly stupid.

Outside of entertainment where software is a direct consumer product, the developer's productivity comes from increased efficiency of use of other productive resources. You can't eat code, but you can eat food that comes from higher production due to better software. So software has a multiplicative effect on existing production. That is, GDP.

Now even added value of entertainment software (games etc) depends on total GDP, because people have to pay with something for that entertainment.

So average developer's productivity IS a function of GDP, with different coefficient depending on the structure of a economy.

A primitive non-mechanized agricultural economy would have a coefficient of near zero because there's almost nothing to automate.

>Anyway GDP per capita using PPP (purchasing power parity) is seen as a fairer comparison.

A fundamentally wrong metric because pay is nominal.

duckingtest··on Spain Runs Out of Workers with Almost 5M Unemployed
Switzerland does have higher average pay CHF 91,374 = $93,703.5 [0] compared to USA $68,082 [1]. Their nominal GDP per capita is 36.62% higher and the pay is 37.6% higher.

Norway interestingly has almost the same pay as USA - $68,737 [2], probably because of high share of oil extraction in GDP (22% [3]) which skews the result. If you subtract oil share from the GDP, you get $56,195.88 nominal GDP per capita, which is almost the same as the American one ($57,220)!

Now Luxembourg is a tax haven/financial center with a population of half a million so I don't think it's a relevant comparison. Just due to population to get something close to true pay average you would have to ask a relatively (to other countries) very big percentage of their developers.

duckingtest··on Spain Runs Out of Workers with Almost 5M Unemployed
I don't think it's that developers are underpaid in Europe. They are just objectively less productive there. After all it's a very specialized job that requires modern, developed economy open to disruptions to be really productive. On the extreme opposite end of a spectrum - a pre-industrial economy - a developer's productivity would be zero.

American nominal GDP per capita is 2.13 times that of Spain's and 1.38x that of Germany's, and the distance keeps increasing. There are many possible causes, but I think lower salaries are a symptom.

duckingtest··on What is the difference between deep learning and usual machine learning?
While there are newer algorithms (almost all first order btw), one of the most commonly used for deep convnets, sgd with momentum, is from the 80s. It really is mostly about computing power - one gtx 1080 has more tflops than world's fastest supercomputer till 2001 [0]. The actual speed difference is probably an order of magnitude larger due to an absence of communication overhead and latency inherent in sharing work across thousands of separate cpus and lots of slow ram. That would make one gtx 1080 equivalent - for neural net training purposes - to a supercomputer from 2004.

duckingtest··on This is not a place of honor
I don't want to sound evil... but why? It's not like digging up low-intensity radioactive waste is going to end the world. Just look at how alive Chernobyl zone is... So let's say some people bring it up, they get sick and die, which makes people remember that radioactivity symbol = bad for the next several hundred years or so.

On a related note, wouldn't it make more sense to turn the radioactive waste into powder and dump it over a large area of sea or desert (Sahara is HUGE)? Given a large enough area it wouldn't even be detectable.

duckingtest··on Bank of Japan Is an Estimated Top 10 Holder in 90% of the Nikkei 225
That's not proven physics, just speculation. There are no answers at this point, especially regarding end of the universe.

Also, infinite universe is not necessarily the same thing as a growing one.

For all we know all we see could be some local quirk of spacetime or whatever that creates a weird projection. I would at least wait for a return data from a probe in nearby star system's before accepting that yes, that's probably how it actually is, at least in our larger neighborhood.

Except the universe seems to be infinite, so yes, the economy can grow exponentially forever. Even within current physics, it's possible to put billions of habitable Earths in our solar system, by importing mass and energy from other systems. There's A LOT of empty space.

Given interstellar distances, the annual rate of growth would be small, but still positive.

duckingtest··on Is Bitcoin breaking up?
>Performance test data shows 32MB is the absolute maximum block size you can handle on a modern desktop PC today [2].

No, it's maximum size you can handle using a single-threaded poorly-optimized cpu software.

>Additionally, a profile of the CPU usage of this node, using golang’s great profile capabilities, shows that the CPU usage is dominated by the ECDSA signature verifications

OpenCL on gpu can easily process 50 MILLION bitcoin addresses per second (ecdsa + sha). [0] Note that OpenCL is available even on smartphones. For a very rough estimate, Adreno 530 on Snapdragon 820 has 500GFlops, 10% of 780 ti which can do 50M/s, so it should do about 5M/s. So a $400 smartphone should be more than enough to process 32MB blocks - provided the gpu is used.

duckingtest··on It's the cities, stupid – Jane Jacobs' macroeconomics (2005)
The way I understood it: transaction costs matter much more than most people think they do.

City is efficient because transaction costs (transport and communication distance for workers and suppliers) are low. However, that's a function of technology. The cost of communication is getting more and more independent of distance; with full vr, it's going to be zero. Price of transport as function of distance would get to zero with teleportation technology.

Unless I missed something, it seems weird that several books were written on such a simple observation.

duckingtest··on How Can There Still Be a Sex Difference, Even When There Is No Sex Difference?
>strong correlation exists between a country's measures of gender inequity and the size of the math gender gap both at the mean and the right tail of the distribution

1. How does that correlation disprove it? It's entirely consistent with one common cause for all inequalities.

2. "Mean gender gap" is for people who did school-related tests, mainly PISA, not the general population. If the greater variability is true there will be much more severely mentally retarded males unable to even read. Depending on the size of the effect, the different mean could in fact confirm the hypothesis (that the mean is the same but std is greater).

3. No analysis whether the distribution of countries' result is consistent with greater variability for the whole human population. Especially jarring when they mention Iceland, a country so small that there are many individual schools elsewhere with more students than they have.

>These findings challenge the Greater Male Variability Hypothesis, which, if valid, should hold for all representative populations, regardless of ethnicity or nationality.

4. That's an entirely unwarranted assumption (in addition to 3). Are Asian-Americans in particular really representative of a general Asian population (with an American culture)? What about brain drain? The more recent the immigration, the harder it's to get in; simplifying for the sake of an example, if you only allow those with a X234 mutation in a B5 DNA location, don't be surprised when there's zero variability in a B5 location.

Even without a filter, why should the standard deviation in math skills be identical between genetically different populations? The identical variability should be true for the X-chromosome in general, not math-skills in particular.

duckingtest··on U.S. GDP Shrank in Q1 2015
Financial markets are a way to sell and buy information, the arrangement of a productive forces in the economy. Profit is the result of selling information - arranging productive forces - that increased output. Loss results from decrease.

The difference between a human and a ~80kg pile of basic elements is their arrangement. So unless the two are equivalent to you, you can't claim the arrangement has no value.

So no, nobody is losing. On the contrary, individual profit is only a fraction of the added value to the economy, because the counterparty is doing the exact same thing. Every voluntary trade is done in expectation of profit by both sides. When on average that expectation is more right than wrong, economy grows.

duckingtest··on What I’m Teaching my Son about Money
Land is special because it can't be made. Imagine that you land on some planet, with no way to go back. You can work remotely using the intergalactic internet. It turns out you're the second guy there, the first guy now legally owns all the land. He agrees to rent you some land for living, at the maximum price you are capable of paying. Isn't he capturing your labor?

It's still 'beneficial' to both parties, because if you don't pay you will get legally killed for trespassing by police robots.

That's the situation on Earth, except 'the guy' is 'older generations' and the homeless are generally allowed to sleep rough on public land in most countries. Also no intergalactic internet.

duckingtest··on What I’m Teaching my Son about Money
It ignores the fact that, for every transaction that was made, the other side also made a profit. Saying that the man is time-shifting the grain is equivalent to saying that the farmer is time-shifting money. On the average, profit is half of added value. Spending half of added value doesn't "almost perfectly cancel out all the good you did".
