mandelken··on Google confirms Play store will continue to function for existing Huawei phones
Huawei is not owned by a communist party. Even google will tell you that much..
mandelken··on The Anhei tokamak is first in the world to generate 100M degrees Celsius
You can not make a bomb with fusion materials alone. Hydronuclear bombs use fission materials (uranium, plutonium) to start the fusion reaction.

However, maybe a fusion reactor may be used for fission bomb research, but I'm not sure how.

mandelken··on Sci-Hub and Alexandra Basic Information
Kim Dotcom is facing extradition to US (where he has never been) over copyright charges, so definitely "extraditable" as you say.

Luckily for her there are no US drone strikes in Kazakhstan...

mandelken··on Thousands of scientists run up against Elsevier’s paywall
> Sci-Hub is not a legal alternative

Depends on where you live. In my country it is perfectly legal for scientific or teaching purposes. And any article with a Belgian author has to be freely available by law max 3-6 months after publication (depending on the field).

It can be argued that reading scientific articles is a basic human right, see art. 27 of the UN declaration: "Everyone has the right freely [..] to share in scientific advancement and its benefits."

mandelken··on How Water Heaters Have Evolved into Grid-Scale Energy-Storage Devices (2014)
Using electricity to heat water is a waste of a high quality (i.e. low entropy) energy source. Carefully tuning when to use electrical water heaters and calling this energy storage is not quite right.

There are much better ways to heat water for domestic use, depending on the climate and context, such as solar panels, heat pumps with ground drilling, industrial heat waste, etc. These are standard technologies being used in large parts of the world.

For more info I recommend the excellent book Sustainable Energy Without the Hot Air by MacKay (pdf freely available at withouthotair.com).

mandelken··on German exclaves in Belgium separated by a bicycle path from the rest of Germany
They are not suspending the Schengen treaty, obviously. The treaty explicitly allows for temporary border controls. Crossing the border to offload migrants on the other hand is obviously illegal.
mandelken··on Targeted advertising has become the norm on the internet, and it's hurting us
> Though the rule was far from universally respected, 20th century journalism's code of ethics prohibited financial considerations from influencing news coverage.

This is a fairytale. Chomsky and Herman wrote Manufacturing Consent 30 years ago where they popped that bubble.

mandelken··on Why Democracies Are Turning Against Chinese Influence
> the US gov't hasn't been kidnapping many booksellers in the past decade.

Are you serious or just trolling? The US has intervened more than any other country over the last decade. As we speak unmanned US drones are killing and dismembering innocent people.

> And despite a bunch of nasty undemocratic stuff happening in the US, there were a lot of underhanded things going on in recent political events in HK.

That's why I said on par with US and Europe. HK is not Switzerland, but not the undemocratic hell some are making it to be.

mandelken··on Why Democracies Are Turning Against Chinese Influence
You are mistaken, freedom of expression in Hong Kong is on par with what you have in US or Europe. From my own experience, the media is even more independent than in Europe/US and definitely less of a police state than some parts in the US.

Remember Snowden moved to Hong Kong to get his story out.

mandelken··on Georgia Tech Creates Cybersecurity Master’s Degree Online for Less Than $10k
Or move to Belgium/Germany where university education costs less than a thousand per year.. And you may enjoy a proper beer as a student.. Afterwards universal health insurance and unionized labour.. All debt free.. Cheers!
mandelken··on Taxi deregulation coming to Finland
Taxi's don't scale in an urban environment. Their use is exactly for night or irregular use. Go to Mumbai, Jakarta, or any low income country and you'll find yourself stuck for hours in a cheap taxi. We need regulation because the market will not build railroads and metro's.

"A developed country is not where the poor drive a car, but where the rich take public transportation". Visit and compare Switzerland with Egypt/India/... and you'll see.

This blog post is a good starting point on the current shortcomings and design solutions of dataframes in Julia: http://julialang.org/blog/2016/10/StructuredQueries

mandelken··on Why Land and Homes Actually Tend to Be Disappointing Investments
This article misses one crucial point: leverage. People can afford to buy a property many times their current savings with a mortgage based on their income, because the government in effect guaranties the credit risk in the US or subsidies it in other countries. For most citizens this is the only way to obtain wealth. If you are already wealthy then, yes, land might not be your best investment choice, but chances are you aren't (see Piketty).
mandelken··on We Need a Better PC
I bought the first Zenbook UX31 when it came out and last year bought a retina MBP. The zenbook was at the time half the price for the comparable mac air and I enjoyed it very much the first year, but since then I had it repaired 3 times costing me more than the purchase price (HDD, ram, power plug) and the power plug still doesnt work well so I can't use it anymore. It served me well, but not sure I would recommend it again. I'm very happy with the MPB so far, never thought I'd buy a mac but there was just no alternative for build quality, as the article suggested. Still haven't put Linux on it, which I thought I'd do immediately, so the OS is not that bad. If the MPB were a little lighter, it would be the perfect machine for me.

Is there a fundamental problem with mesh? Why couldn't that work in combination with something like maidsafe?

Just thinking out loud here.

At the last Belgian Julia meetup there were 2 local companies present (10+ employees) that do all their development in Julia: http://www.tangent.works/ http://www.dynactionize.com/ I understand Blackrock has been sponsering the debugger work.
