What does 32 vs 64 bit have to do with security? I'm genuinely curious...
What is has to do is that the architecture that brought 64bits (AMD64), also brought several security features (like NX bit) among others.
32bits software might be targeting architecture that predate the NX bit (e.g.: if you still have an old 32bits.EXE that dates back from the Pentium 4 era, it might be writing to and executing from the same memory area), and perhaps Windows could theoretically not enable NX for 32bits legacy software on these grounds? (to avoid to break old 32bits software ?) By accelerating the deprecation of 32bits software, they might try to deprecate the non-NX software ? (That is pure speculation on my part. I have not enough experience with Windows)
(register vs. stack pressure is also different between the 2 architecture. AMD64, in addition to 64bits, also brought twice the number of registers. meaning that more things can be kept on CPU and less needs to be written to the stack. Which could mean less potential candidate in case of stack smashing exploit. But I'm really going on a limb here. Return address is way more interesting to abuse in this case than register value. It's definitely less probable reason than NX).
I doubt that software would be affected easily by any other difference between the two (e.g.: warp around at different values, 0x7fffffff vs. 0x7fffffffffffffff That is highly unlikely : win64 is a LLP64 platform - all integers are still 32bits (both int and long), unless explicitely required (long long, hence the LL) and thus all value still wrap similarily between same source code software compiled for 32bits and 64bits. only pointers are promoted to 64bits (hence the P) and thus only point math would wrap differently)
Not just that, but this sounds like an approach you could adapt to any virus.
Well, given how/why CRISPR/cas9 evolved in prokaryote in the first place.
Prokaryotes ended up with this systems because it helps them remove foreign DNA (phages, plasmids). Curing HIV is about removing its foreign DNA from the infected white blood cells.
So CRISPR could be applied to curing viruses such as VIH. Hey, what a surprise !
Yes, it could be used to eliminate tons of currently hard to cure viruses.
(Note: I'm not belittling the accomplishment of the researcher who developed this cure candidate. There's surely a lot of work done to addapt to this use.
I'm just saying is that these kind of application is what bacteria evolved CRIPR for in the nature, so it's not surprising that we could apply it for a similar task in eukaryote regarding viruses.
It's the "weirdly simple gene editor" use that is unexpected)
Though not necessarily. Fat tissue can disbalance hormonal regulation. Among others, you end up with less sensitivity to insulin. (so you end up with a type 2 Diabetes, because of your fat - which might be caused by other causes than you processed sugar intake, not because of direct influence of those intake)
Obesity is caused by eating too many calories.
...combined with not doing to much exercise. Which will encourage the body to use these excess calories to build "reserves, just in case". (As opposed to other uses for calories : - burning them, to move muscles - burning them for thermal purpose - use them to rebuild muscles).
Whereas, doing lots of exercise, in addition to the direct consumption of calories (you need energy to move), will also raises a bunch of hormones stimulating muscle growth/repair/up-keep, so calories will be also burned and used in the "construction work" in keeping those muscles.
Only the latest generation of AMD card is somewhat useful - and it benchmarks well below any nVidia card.
...for a smaller power budget and cheaper price. AMD simply doesn't produce cards in the ultra-high-range category.
For years, the nVidia driver has had the odd quibble
Like Optimus not working at all on dual GPUs. Like modesetting completely getting fucked-up on some laptops (including a few of mines). Like display not surviving suspend/resume cycles on some laptops (including a few of mines).
(Note: all the above boil down to : Nvidia decided to not play nice with the kernel facilities that everybody else accepted to use, like DMA-BUF and KMS respectively).
AMD's drivers over that same timeframe have been horrible.
AMD's *closed source* driver (the old one : fglrx/catalyst) used to be horrible.
AMD also had provided documentation to opensource developpers (I think it started not long after acquiring ATI) (And later on even had opensource developers on their payroll) This enabled things like r600 and radeonsi drivers. Which did work nicely (in my experience: even on the Radeon HD 3800 and 4600 I used to have back then). To the point that r600 got quickly declared their official driver and fglrx phased out for that generation of hardware (VLIW, pre-GCN)
Don't whitewash the history of how things rolled out due to the latest 6 months of development work by AMD....
Don't demonize AMD based on their sole (old) closed source driver, while they have been putting (successfully) lots of exemplar efforts behind opensource for nearly a decade.
Welcome another round of API/ABI breakage: even the latest beta NVIDIA drivers 381.09 are not compatible with this kernel.
Meanwhile, opensource drivers, that are part of the kernel all work.
Intel's opensource driver : - development paid by Intel themselves - works with Intel's own opensource openGL driver) IT WORKS
AMD's opensource driver : - development paid, among other, by AMD themselves (but also by Valve) - works with both the opensource driver (whose developement was among other paid by AMD, and is considered the future official driver) - and the closed source AMDGPU-PRO (that AMD is putting, until the opensource catches up (openCL and Vulkan not up to par yet *) and for the few professional CAD workstation users that needs some weird feature that AMD is never bothering to port to Mesa) IT WORKS.
Only NVIDIA persist in doing things their way (because it enables them to simply cross-compile** their Windows drivers to Linux, even if that breaks most facilities used by everybody else - see Optimus, etc.). And only collaborates once in a bluemoon with the Nouveau developpers when it helps their agenda with Tegra mobile GPUs (where Linux support is a must). (And because of that, even the opensource Nouveau that had to be developped from scratch by unrelated 3rd parties - is problematic) INSERT LINUS' "FUCK YOU NVIDIA" PIC
So stop blaming Linux dev's for Nvidia's wrong doings. Everyone else plays nicely with Linux and it works. Only Nvidia decide to fuck up everything and go against everyone else and you see the end result.

* : OpenCL is in the process of getting ported by AMD on their ROCm opensource computing platform. Once that is done, AMD will officially have a good quality opensource OpenCL.

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.
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.
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)
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.
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).
SF, LA, Chicago, Detroit, NYC, all full to the brim with ridiculous amounts of homeless people sleeping on the sidewalks 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)
TODO: Change your US warranty laws, so such bricked device must be replaced for free. (See europe for an example)
(It's a device. It was used as it is supposed to be by the end user. The end user didn't subject it to any abuse. The device suddenly stopped working unexpectedly. It has to be replaced under warranty).
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...
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.
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
In the era of Microsoft's own AV, there is no need for a third-party AV installed on Windows.
Nope, quite the contrary : There IS need for third-parties too.
The more diverse the antivirus landscape is, the more AV virus-writer needs to test their creations against. Avoid monoculture ! It's harder when a Virus needs to go unnoticed by all of Microsoft AV, Kaspersky AV, Avira, F-Prot, Clam, etc. rather than only the first one on the list.
Why do people do bitcoin? 1) To operate anonymously outside the system.
For the last time BITCOIN IS NOT ANONYMOUS. BY DESIGN.
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)
A leading "fact-check site" regularly uses this bit of dissemblance to describe right-of-center incidents, while left-of-center equivalents seem to get "True" or at least "Mostly true."
It's fun that in a thread where you criticize fact checking and citing sources, you didn't actually mention which site you're talking about (politifacts, I presume ?) nor precise numbers.
(not that I've pointed to litterary / dictonnary sources either).
With new points being added daily, the landscape of UK charging point infrastructure is continually changing.
You might have missed the recent news but UK stopped being part of the European union. (And EU regulation were big point on Brexiters' agument list).
Now for the detail : - EU standard is Mennekes and Combo (the later is a backward compatible super-set of the former. You can charge a DC enabled car, with AC Mennekes charger - you'll only be limited to the maximum current of the AC). Together, even in the UK, Mennekes and combo account for more than half the cars. - Mennekes and Combo are a recent standard (2013). Chademo is still getting phased out (and this will take time until it disappears, as there are still cars using it on the roads - mostly japanese brands where the standard was developed). But you can see on the yearly graph that there is a stagnation of Chademo between 2015 and 2016, and that there's an explosion of Mennekes and Combo over 2014/2015/2016.
If you look at current european car statistics : - the top selling cars of 2017 (Zoé and Leaf) are Mennekes based. That gives you a nice idea of where the current trend is heading.
CSS (a.k.a. "Combo") for DC and Type 2 (a.k.a. Mennekes - the same but without the 2 extra pins for DC) for AC are the two official standard in Europe for electric cars. Any no-name/3rd-party high-power station I've seen here around feature Mennekes connectors (random example : on the parking lot of local IKEA) or Mennekes+Combo+Chademo (random exemple: the nearest highway gaz station).
It might be different on your side of the Atlantic pond. But in the old continent, Mennekes and CCS are the dominant connectors by official standardisation.
It's really the same situation as Apple with Lightning Port(NIH syndrome) vs. everyone else micro-USB 2/3 (also an Euro mandated standard).
Though to Tesla's deffense : - Even if the connector exists since 2009, EU declared it the official standard only in 2013, one year later than Model S' 2012 official launch. - I've read somewhere that european Tesla's and Super charger network use a modified connector that is more-or-less with a Mennekes-compatible shape (though still doesn't send DC on CCS pins) so at least they're halfway there.
No. There is a market for other car makers to make and sell the adapters.
Yeah, but who pays for the super-chargers? - If Renault pockets all the money for Zoé-to-Tesla converters, and Opel pockets the Ampera-to-Tesla, etc. how's Tesla supposed to pay to build the towers ?
Tesla has to contibute in some ways to the converter in order to get cash. - I suppose there is probably some form of handshaking to validate access for the car/converter (in the past, it used to be that super-charging was a paid separate option)
(And besides, they're the one producing NON-standard connectors. The rest of Europe has moved to Mennekes for AC and Combo for DC (mostly similar DC goes on 2 extra pin). Though I've read that Euro market Teslas and chargers seem to have moved to a proprietary that is more or less shaped closer to a Mennekes, so they are at least half-way through.)
They do not want EV sales. And Tesla spots are already full.
The success of EV in Europe begs to differ. (e.g.: Zoé is extremely popular in some markets)

it's called SUN LIGHT (Yeah I know we
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)
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.
I care HOW they are USED.
They tell you in the summary, so your friends can tell you if your outfit is cute.
I think what the above poster wanted to say would have been more appropriately expressed as
HOW they are ABUSED
Sorry, can't hear you.
Over the noise of a billion of 4chan creepy online freaks fapping at hacked pictures of said teenage girls.
and
What. Could. Possibly. Go. Wrong.
I think this deserve a new concept of "Nope-finity" to be invented, just to have a proper answer.
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).
SF, LA, Chicago, Detroit, NYC, all full to the brim with ridiculous amounts of homeless people sleeping on the sidewalks
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)
TODO:
Change your US warranty laws, so such bricked device must be replaced for free. (See europe for an example)
(It's a device. It was used as it is supposed to be by the end user. The end user didn't subject it to any abuse.
The device suddenly stopped working unexpectedly. It has to be replaced under warranty).
That will teach the manufacturer of shitty goods.
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: http://www.worldstandards.eu/e...
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.
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 : ...and a couple of others that I'm too lazy to properly research.
- 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)
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
In the era of Microsoft's own AV, there is no need for a third-party AV installed on Windows.
Nope, quite the contrary : There IS need for third-parties too.
The more diverse the antivirus landscape is, the more AV virus-writer needs to test their creations against.
Avoid monoculture !
It's harder when a Virus needs to go unnoticed by all of Microsoft AV, Kaspersky AV, Avira, F-Prot, Clam, etc. rather than only the first one on the list.
Why do people do bitcoin? 1) To operate anonymously outside the system.
For the last time BITCOIN IS NOT ANONYMOUS. BY DESIGN.
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)
Yeah it is, that's the exact definition of majority.
Unless you're speaking about Hashing College majority. That one trumps over Popular Hashing.
Except that in the case of crypto-currencies, you can add a few trailing zeroes after the significant number.
A leading "fact-check site" regularly uses this bit of dissemblance to describe right-of-center incidents, while left-of-center equivalents seem to get "True" or at least "Mostly true."
It's fun that in a thread where you criticize fact checking and citing sources, you didn't actually mention which site you're talking about (politifacts, I presume ?) nor precise numbers.
(not that I've pointed to litterary / dictonnary sources either).
Really?
From that page:
From the top of the same page (emphasis mine):
You might have missed the recent news but UK stopped being part of the European union.
(And EU regulation were big point on Brexiters' agument list).
Now for the detail :
- EU standard is Mennekes and Combo (the later is a backward compatible super-set of the former. You can charge a DC enabled car, with AC Mennekes charger - you'll only be limited to the maximum current of the AC). Together, even in the UK, Mennekes and combo account for more than half the cars.
- Mennekes and Combo are a recent standard (2013). Chademo is still getting phased out (and this will take time until it disappears, as there are still cars using it on the roads - mostly japanese brands where the standard was developed). But you can see on the yearly graph that there is a stagnation of Chademo between 2015 and 2016, and that there's an explosion of Mennekes and Combo over 2014/2015/2016.
If you look at current european car statistics :
- the top selling cars of 2017 (Zoé and Leaf) are Mennekes based.
That gives you a nice idea of where the current trend is heading.
CCS doesn't dominant as you suggest.
CSS (a.k.a. "Combo") for DC and Type 2 (a.k.a. Mennekes - the same but without the 2 extra pins for DC) for AC are the two official standard in Europe for electric cars.
Any no-name/3rd-party high-power station I've seen here around feature Mennekes connectors (random example : on the parking lot of local IKEA) or Mennekes+Combo+Chademo (random exemple: the nearest highway gaz station).
It might be different on your side of the Atlantic pond.
But in the old continent, Mennekes and CCS are the dominant connectors by official standardisation.
It's really the same situation as Apple with Lightning Port(NIH syndrome) vs. everyone else micro-USB 2/3 (also an Euro mandated standard).
Though to Tesla's deffense :
- Even if the connector exists since 2009, EU declared it the official standard only in 2013, one year later than Model S' 2012 official launch.
- I've read somewhere that european Tesla's and Super charger network use a modified connector that is more-or-less with a Mennekes-compatible shape (though still doesn't send DC on CCS pins) so at least they're halfway there.
No. There is a market for other car makers to make and sell the adapters.
Yeah, but who pays for the super-chargers?
- If Renault pockets all the money for Zoé-to-Tesla converters, and Opel pockets the Ampera-to-Tesla, etc. how's Tesla supposed to pay to build the towers ?
Tesla has to contibute in some ways to the converter in order to get cash.
- I suppose there is probably some form of handshaking to validate access for the car/converter (in the past, it used to be that super-charging was a paid separate option)
(And besides, they're the one producing NON-standard connectors.
The rest of Europe has moved to Mennekes for AC and Combo for DC (mostly similar DC goes on 2 extra pin).
Though I've read that Euro market Teslas and chargers seem to have moved to a proprietary that is more or less shaped closer to a Mennekes, so they are at least half-way through.)
They do not want EV sales. And Tesla spots are already full.
The success of EV in Europe begs to differ. (e.g.: Zoé is extremely popular in some markets)
