Element_··on India has launched a 648MW solar power plant
This article gives some images that show the scale: http://www.aljazeera.com/news/2016/11/india-unveils-world-la...

Element_··on All Tesla Cars Being Produced Now Have Full Self-Driving Hardware
My understanding is because Tesla has to send their data over the cell network it is first heavily processed/reduced by the cars onboard computer before being sent back (in order to conserve bandwidth). So I am not sure if it's fair to compare the 2 company's datasets based on miles driven alone.
Element_··on All Tesla Cars Being Produced Now Have Full Self-Driving Hardware
Will this new neural net and hardware be capable of advanced object detection?

For instance if a plastic bag or piece of cardboard rolls across the highway a human driver knows it's safe to run over without stopping. Would a system like this just see an obstacle via radar and emergency brake?

Google has been working on this problem for longer and they have access to the largest image/video datasets in the world to train their models. I wonder how google and tesla systems would compare.

Element_··on Goodbye, Ivory Tower. Hello, Candy Store
I remember once reading that investing in Monster Energy Drink stock 10 years ago produced a greater return than any of the FANG stocks.
Element_··on Netflix crackdown on border hoppers could kill some unblocking companies
Yes, they are using some kind of heuristics in addition to ip ban lists. I was using an openvpn instance on a private US server which was working fine until a couple weeks ago when I didn't notice the VPN connection dropped and accidentally reconnected from 2 different countries quickly. It banned me immediately.

Element_··on Ask HN: How was your experience using parse.com?
I have been prototyping an app on parse over the last month, I've been pretty disappointed. Mainly with regards to their database system. As others have pointed out there's insane limits on things like count queries. There is 1000 record limit on queries in general. The performance of cloudcode between the db is awful, you have to batch everything into tiny operations or risk timeouts. Skip has a 10k record limit. Their web based data browser tool seems unfinished, for instance you can't even insert into relational columns and deleting 100 records at a time locks up my browser.

This guy has compiled a good list of limitations: http://profi.co/all-the-limits-of-parse/

It may be okay for very simple applications but for anything non trivial or with a large db I would not recommend it. Any time saved by having a PAAS out of the box is lost trying to work around all the weird data access limitations.

Element_··on The Satoshi Nakamoto Email Hacker Says He's Negotiating with the Bitcoin Founder
To "use Satoshi's identity" would require his pgp key (at a minimum).

Title is a little misleading. Yes the car was forced into reduced power mode to cool down the battery however overall the professional driver at the wheel said he was impressed by the car.

“Now, I have had the pleasure of driving a huge number of cars, both on the Nürburgring and off, but this would be my first time in a Model S or any fully electric car. And I have to admit I was pretty impressed,” Holland writes."

It would be cool if Tesla sponsored a racing team that could work on some of the issues that came up during the test drive.

Element_··on U.S. military grounds F-35 Joint Strike Fighter after fire
They are flying from: Patuxent River Maryland to: Fairford England which has a direct flight path of ~5800kms. The range of the F35 is ~2200km plus they need to maintain emergency fuel reserves and might fly a less direct path to stay near land. They are taking 2 kc130 air tankers for the trip.

Element_··on U.S. military grounds F-35 Joint Strike Fighter after fire
The US military was planning to fly 5 f35's across the Atlantic for the Farnborough airshow next week in an effort to shore up support for the UK purchase. They were originally supposed to be there by June 29th so this is another delay. Looks like they haven't made a final decision on the trip yet (not sure if I would want to be one of the pilots flying these things across the ocean, a trip that requires ~10 aerial refuelings)

These would be great on planes/trains/buses where wifi isn't readily available. These days the passengers probably carry enough content on their mobile devices to keep everyone entertained during a long haul flight they just need a way to share it.
Element_··on Middle class leaving San Francisco, census says
There was a segment on PBS news hour yesterday that mentioned police officers in California are making 100-250k+ a year and are able to retire with 6 figure pensions & full union benefits. I think most people would class policing as a middle class job.
Element_··on Here be Fusion – A Visit to General Fusion
You are over thinking it...the outlet port to circulate/drain the molten metal would be the same hole the lower plasma injector uses. By using a curved surface it can take advantage of the centrifugal force and surface tension of the liquid metal to prevent the metal from falling down lower into the injector. So basically there is a doughnut shaped orifice around the top of the lower plasma injector that's connected to a pipe which feeds into the liquid metal circulation system. Here is a cutaway drawing where you can see it: http://1.bp.blogspot.com/_VyTCyizqrHs/ScF7J2w-TOI/AAAAAAAADL...
Element_··on Here be Fusion – A Visit to General Fusion
Ever since reading the original Popular Science article on this company it has amazed me how little attention it has received in the media. It seems like they are really on to something and their budget compared to other fusion projects is tiny. I hope they receive continued funding.

To prevent capturing them you could charge a deposit equal to the cost of the drone, when the drone returns safely you get your deposit back.
Element_··on Here’s who probably did that $150 million Bitcoin transaction
Traditional currency isn't really anonymous. Sure it is theoretically possible to do an anonymous 150 million dollar cash transaction in USD but in practical terms it's basically impossible without a great deal of money laundering. I believe by law in North America banks have to report any cash transactions >= 10k per 24 hour period to the government. Additionally every bill has a traceable serial number on it.
Element_··on Ask HN: For Bitcoin to be ubiquitous, what must happen?
A way needs to be found to scale the network to a size that can't be interfered with by a nation state(s) before a nation state(s) interferes with it. (e.g. if btc network gains serious traction yet is small enough a nation state can interfere/control the network, a nation state will eventually interfere/control the network)
Element_··on Bitcoin $500
The US gov waited until eGold was doing ~2 billion in transactions annually before it moved to shut it down. Given the growth rate of btc it just recently became big enough to get the attention of the federal gov. I think it is certain the US government will attempt to shut it down more a question of when and how elaborate their attempt is (e.g. Will they try to: arrest a few btc users, dump large sums of money into the btc markets to destabilize it, or build a cluster larger than the entire btc network).
Element_··on Ask HN: What would kill Bitcoin?
The US government took down egold when it reached ~2 billion in annual transactions. I suspect they will take action against bitcoin before it reaches a trillion dollar monetary base, but only time will tell ;)
Element_··on Ask HN: What would kill Bitcoin?
Bittorrent/TPB ticked off a small number of industries (media,software, etc...) their persecution was largely a function of how well those industries could lobby the government.

If bitcoin ever got large enough to be perceived as a threat to USD (which is a long ways off) the bitcoin community would not have the resources to take on the US gov. Being geographically spread out is irrelevant. For a small fraction of one of its many defense institutions annual budgets the US gov could easily build an ASIC cluster larger than the entire bitcoin mining network. They could even just start maliciously buying/selling large quantities of btc to keep the btc market volatile. To put it into perspective: btc current total market cap is ~4billion, and the NSAs annual budget is ~12billion.

Element_··on My Friends and I Bought an Island
Canada may be a big winner from climate change but it won't be because of permafrost. Melted permafrost is essentially swamp land, development is generally much easier when it is in the frozen state. Oil companies go so far as to install passive cooling radiators on oil pipelines to keep the ground they are built on frozen.
Element_··on New NSA Leak Shows MITM Attacks Against Major Internet Services
If the NSA is doing this "legally" via secret courts etc... Then you have to assume every company subject to US law can't be trusted.
Element_··on Amazon Ramps Up $13.9 Billion Warehouse Building Spree
I was also curious about this, I assumed the competition between UPS and Fedex was fierce enough to keep them both fairly innovative, but it sounds like Amazon is finding room for improvement...
