Comment LCD grating (Score 1) 52

managed to find the answer my self.

apparently, some display have an *LCD* stereo grating barrier.
i.e. the barrier it self is a second black-and-white transparent LCD stacked above the main colour screen.
thus the barrier can be turned on or off

some autostereo displays even feature alternatives grating. by switching fast enough between odd and even columns, grating can change whitch eye sees which half of the display.
thus these fast-switching display can increase their visible resolution by horizontal interlacing.

Comment software controlled ? (Score 1) 52

You could always turn the 3D slider all the way down to "off" which puts the display into 2D mode.

yup, this part i understand : slider controls how much horizontal separation between the pictures generated and sent to each eye.

In fact, it turns off the lenticular grating too so it's not just faking 2D using a 3D screen.

huh? how come? you mean the separation into left and right side is software activated ? that you can actually shut it down and gain twice the horizontal resolution?
how does this software controlled grating/lenticular work?
i'm genuinely interested.

Comment Steered beam: yes. (Score 1) 136

EVEN with beam steering, where the whole half-watt of power from the router is aimed directly at your phone,

There's a frenquency range above the 400 THz mark, that can be efficiently steered, and could be collected on the back of your phone :
it's called SUN LIGHT (Yeah I know we /.ers are not very familiar with this strange energy beem, being basement dwellers ourselves).

I think that's what the above poster jokingly referred to when saying to go to higher freqency.

(And for the record, a solar cell the size of a modern huge smartphone could probably collect ~2-3W of power.
There are actual power banks produced with 12x12cm sollar cells that selfcharge them in the 3~5W range when exposed to the sun)

Comment Joke : Woooosh (Score 1) 136

These "lots" of energy you are talking about are not nearly enough for a modern smartphone.
Even if you would make use of the electromagnetic radiation coming from a nuclear fusion reactor, and position your phone optimally, a harvesting panel the size of a smartphone would barely be able to gain 1W.

I think you missed the joke because when around a couples of hundreds THz, said nuclear fusion reactor emitting the electromagnetic radiation is called the sun.

So we're more speaking about 3W range. (3.5W for 12x12cm)

Still not enough to fully power a modern smartphone monster with both CPU and GPU on full gear.
But solar charging is actually really a thing.

Comment Spreading/sharing (Score 1) 82

Also do not forget that if sharing is what you want (so granma and granpa can see video of their grandkids) :

- Tarsnap, Dropbox, Google Drive might be more expensive for equivalent storage size / bandwidth. But at least there's less risk for them to go belly up.
(Even if there's risk for those with non-free/closed-source clients to rape your privacy).
And you should keep a local copy on your NAS anyway.

- You can serve the files from your NAS (lots of them feature file server), and YOU can control the protection (e.g.: GPG-encrypted files. Or simply AES-password protected Zip archives if your relative are less tech savvy).

For sharing with more users simultaneously (video of your *wedding*. And suddenly all the 20 branches of the family scattered around the planet want them) :
- You can also serve the files over torrent, so you don't need a big bandwidth. Most NAS have also the option built-in.
And again YOU are in charge of the protection (But if you want strong security, just dont use 'Password123' to encrypt the archive, even if that clueless cousin asks for something easy to remember).

No matter what keep a separate local copy (keep a copy on your NAS if you go DropBox. Keep a (non encrypted) copy in a separate non-shared directory on your NAS or a separate NAS if you serve the file themselves).

Democrat run cities seem to be the worst, you can check the stats on that one.

You hypothesis : democrats causes homeless people to run amok (democrats run the cities like shit and let such homeless people happen in the open, instead of ... huh.. rounding them all and throwing them into prison ?)

My bat-shit crazy hypothesis :
Cities with the most homeless people, make their inhabitants more aware of the human misery, which in turn encourages the population to vote for democrat candidate, the closest you have in the US to a socialist party who'll try to spend money on health (specially mental health) and other such social program which might help the homeless people's problems ?
(in other words: exposure to homeless people cause population to vote less far-right)

Change your US warranty laws, so such bricked device must be replaced for free. (See europe for an example)

Comment Plugs standard. (Score 1) 177

The EU can mandate two-pronged mains power plugs as much as it likes, but the UK isn't changing from 3-pronged Type-G, and certainly won't change now.
Don't forget that adapter...

You might not have noticed, but in the UK isn't in the EU anymore...

Nope: In Europe you can encounter plug types C, E, F, G, J, K and L:

I you pay close attention :
- G is only with the weird guy who decided to Brexit any way.
- J is Swiss. See "UK" for more information (and is compatible with C anyway).
- C, E, F, K are all compatible with Europlug (C & E/F). In theory some combination are less safe due to absent grounding, but in practice modern manufacturer tend to build their plugs and socket intelligently (e.g.: notice how the same plug in E & F has contacts for both type of grounding. Same goes for socket which is able to accept a range of prong width). I strongly suspect that Danemark has the same kind of approach to multi-standard sockets as Italy (Haven't been there to check, but adapters seems to be built this way).
- L : that picture is the theory/past history (and the 10A version is still compatible with C anyway). In practice, in italy, you'll find hybrid connectors that can safely accept with grounding the Europlug (E/F) in addition to both Italian (10A and 16A) and the 2 prong C.

So basically, if you have an Europlug (E/F) you can travel all over the European Union and plug your device everywhere (still have to check if it can safely be grounded in Danemark, though).
You'll need adapters only for UK (not in EU anymore), CH (never was EU to begin with, and still compatible with 2 prongs anyway), and for the occasional old Italian house which wasn't converted to E/F/L hybrid yet (and is also compatible with 2 prongs C).

I have traveled a lot within Europe (except Danemark), I speak from practical personal experience.

Comment Renault. Citroen. Others (Score 2) 177

Tesla is coming out with their 4th model. Who else has at least 3?

(Note I'm not counting proto-types, concept cars).

e.g.: Renault.
the "zero emission" (Z. E.) currently familly covers :
- Twizzy : a tiny in-city micr-car/quad (since 2012)
- Zoé : a small compact (since 2012)
- Fluence : a sedan (since 2011)
- Kangoo Z.E. : a pannel-van (since 2011)
(All of them in production. I ignore the concept cars, because they vary a lot regarding final production models - specially the Zoe)
I mostly know them because I'm mainly driving Zoés through the local carsharing, and they have a lot of marketing/outreach.

Note that : due to intricate difference of the European market (densely populated city centers, most people commute less than 50km per day) Renault went the opposite way from Tesla.
- Cheap small cars (Twizy, Zoe) where released from the nearly beginning, whereas Tesla started with big expensive cars first (went through Roadster, Model S sedan, Model X suv, before finally starting Model 3 any time soon).
- Small battery first (22kWh for all first, then progressively intoducing big batteries - like 43kWh for the current Zoe). Tesla would never stood any chance in the US if they didn't have 50~70kWh from the beginning.
- a tiny flea like the Twizy makes entirely sense in the densely populate cities of Europe (continent known for things such as Smart, Mini, etc. and even BMW C3 scooter). Such class of cars barely exist in the US because you people are affraid of being crushed if you don't own the biggest SUV possible. Tesla would have been laughed of if they attempted something like this in the land of the hummer.
- an electric minivan like Kangoo actually makes sense in a dense European city, even with a 22kWh battery - most typical trips for which such an utility vehicle might be needed are well within the battery's range - Tesla isn't even considering minivans yet.

Nissan is partly owned by Renault, so they probably have similar offerings (quick search returns: New Mobility Concept, Leaf, Kubistar).

Citroën/Peugeot has also several electric models :
- C-Zero / iOn : compact (since 2009)
- Berlingo Electric : van (since somewhere 2008? replaces the 1991(!) C15 electric - these are *really* old tech and use NiCd battery) (Again in Europe this did make sens for their use pattern - Post office.)
- e-Mehari : convertible compact SUV (since 2016) ...and a couple of others that I'm too lazy to properly research.

VW has also a certain choice of electric vehicle :
- eUP! : small compact since 2013.
- e-Golf: compact since 2012
- Camper (yup, the iconic one comes back in electric version) : tough still concept in 2017, full production expected in 2020.

More funny example :
The entire fleet in the Swiss village of Zermatt is build by a local small scale workshop since 1977. It covers a very diverse range of vehicle (taxis, utility, etc.) but these are custom built on a per-unit basis (it's a very small production, only for the village) (also, as the vehicles only drive within the village, range is definitely NOT a problem, and the vehicles can very easily benefit from battery swapping).

There are probably other companies featuring more than a single model. I'm just too lazy to research further.
Again, this is due to Europe being a completely different market from the US.
Range isn't much critical (as mentioned above, most daily commutes are under 50km), electricity doesn't rely on fossils, etc.
And as such electric vehicles have been available for quite some time (as mentioned above : Citroen provided the French Post Office with NiCd powered vans since 1991, Zermat has exclusively electric-only cars since 1977 some still running)
The only change is that general public grew more interested during the past decade and manufacturer began introducing mass-produced consumer-oriented vehicle next to their utility vehicles (Citroen adding the C-Zero for consumers to their offerings with more modern 35kWh Lithium Batteries).

Also some cities started to experiment with electric car sharing schemes (Autolib' in Paris).

Most of the companies currently producing electric sedan cars in Europe, probably have also other vehicle in other category (ultra-mini or utility) that you'll never find in the US due to differing market (it seems to me that everybody needs to drive 200km per comute on your side of the atlantic)

Nope, quite the contrary : There IS need for third-parties too.

Why do people do bitcoin? 1) To operate anonymously outside the system.


The whole point of bitcoin is that it is *distributed*.
Means every single (full) node on the network has a complete copy of the transaction ledger and can independently verify that a balance is legit.
By definition, on bitcoin network *everyone* gets to see *every transaction*.

Bitcoin is at best pseudonymous :
Transactions aren't linked to your Real Identity (a la Facebook), but to a public key.
That public key require a bit of big data mining in order to map to an actual user, due to constant key change. But not beyond the processing capabilities of a state-level entity (it only stops your neighbour to spy on you).

But none the less transaction is anonymous.

The *real* reason why bitcoin is getting popular is because it is *distributed*. There is no single entity (in theory, short of a 51% attack) that controls the network, there is no "Bitcoin, Inc." on which you can put legal pressure to force blocking transactions.
(As opposed to, say, PayPal and Visa/Mastercard refusing to process donation to WikiLeaks).
So government can see you donating to wikileak, but can't do absolutely nothing to prevent it.

The only real anonymous payment method is actual cash.
(nobody has the power to track all the bill numbers)
