  1. It will be the law by Dec 31 2020 that:

    Direct current (DC) high power recharging points for electric vehicles shall be equipped, for interoperability purposes, at least with connectors of the combined charging system ‘Combo 2’ as described in standard EN 62196-3.

    So Tesla charging stations will have to support type 2 CCS. At the end of the day it's all money to them so I'm not sure it is a disadvantage to exclude other vehicles. Elon Musk has made statements that they want to support other vehicles and Tesla is part of the EU charging initiative CharIn so I'm expecting they're playing ball.

  2. By law they'll have to support CCS type 2. Mennekes is the AC charger socket minus the DC part. Tesla figured a way of making DC fast charging work through Mennekes.

    It'll be interesting to see what they do with the model 3. There is little reason they couldn't build their car such that it works with CCS type 2 or their own extension to Mennekes. It would suck for owners to have to use an adapter to use CCS type 2 chargers.

  3. Actually we're both wrong. It's 100Kw. Tesla's supercharging is also over pairs of chargers so it's a theoretical maximum. CCS can match the rates, but as I said lower capacity batteries probably haven't made the need so pressing.

    A company called Better Place has already tried that. You drove your car onto a ramp and a robot arm unscrewed the old pack and stuck in a new one. It didn't take off as a concept and the company went bust.

    Another concept is aluminium-air batteries that are non rechargable but 8x as energy dense as lithium battery and lighter too. The idea is the car has a normal battery (e.g. with 100 mile range) and it could switch to the aluminium-air battery which could offer another 1000. Ordinarily the driver wouldn't tap the second battery but its there if they need it, and it could be switched out when it's exhausted.

  5. CCS has standards for rates up to 120Kw already and 350Kw in the works. A Hyundai Ioniq (for example) can already charge at 120Kw so yes you could charge another vehicle at the same rate as a Tesla. Oddly the Bolt has a 50Kw limit but that's nothing to do with the underlying standards.

    Most other vehicles have lower capacity batteries so perhaps the pattern of charging and usage has been different up until now. Tesla owners might drive longer distances or prefer to charge at a station once a week whereas someone in a Leaf might be driving shorter distances and charging from home.

    I expect that pattern will change in time. EVs like the Ioniq, Bolt and 2nd gen Leaf all have increased ranges and therefore the need for rapid charging will increase. Maybe the Bolt will get a software update or hardware revision for a faster charging rate. I expect that charging stations will receive iterative upgrades over time.

  6. In Europe they will be compelled to because the bloc has take the sensible decision to mandate a charging standard (CCS type 2) and require that all stations charge all vehicles on a non-discriminatory basis through common payment methods. i.e. it works like a petrol station. It doesn't stop stations offering other charge formats but with a common standard those other formats will die out over time, e.g. chademo is basically just the Nissan Leaf at this point and will probably die with it.

    The US should do similar to put an end to all of these competing charging formats and vertical markets. It's not like Tesla will lose out because they stand to profit regardless of which vehicle is charging at their stations.

    It is extremely easy to find comments by former and current X maintainers emphasizing that point relating security, bandwidth use, obsolete code, pixel limits etc. Pretending you can't operate Google and find these comments says more about you than anyone else. Pretending that we should suffer an obsolete windowing system and citing esoteric issues with FVWM is just laughable. If you want X, run XWayland or stick with what you have. Big deal.

    They're a relatively concise way of creating a reusable anonymous function and binding values to them and having the code inline and next to the functionality it's relevant to. This isn't a new concept since C has always allowed function pointers to be passed around (e.g. for qsort) and boost has had function bindings well before C++11. But now they're part of the language and therefore more useful.

    But like all things they should be used with due consideration. C++ doesn't help itself by having horrible syntax for iterating collections.

    Anonymous functions / closures / lambdas are fine for small snippets of code, e.g. iterating loops, firing timers, success / fail handlers etc. When you start nesting them or chaining them together with promises or similar constructs, then things can get really hairy.

    Try writing sets of asynchronous Jasmine tests that use promises, lodash iterators, success callbacks and other things of that nature arrays and madness swiftly follows.

    Perhaps they're daring people to switch to another office product. I don't see how the operating system underneath is of much relevance. Even from that measure, it seems like this move is targeted at companies using an installed product with a business cloud storage. So if someone were to flip office suites, what alternatives are there for that?

    I think the LibreOffice team should be looking at where MS Office is going with cloud storage and make sure their product offers something equivalent. If it does, they can pick up some of the business that needs analogous features before it can jump from the MS train.

    Electric brakes are not exclusive to Teslas. Many modern cars have electric parking brakes that are push button operated and can disengage when you hit the accelerator and can be set to auto engage when you come to a stop, e.g. so you don't roll back or forward on a hill.

  12. Subway's Chicken on Subway Sues Canada Network Over Claim Its Chicken Is 50 Percent Soy (yahoo.com) · · Score: 1
    Here is the ingredients for chicken strips from their own site:

    CHICKEN STRIPS Boneless skinless chicken breast with rib meat, water, contains 2% or less soy protein concentrate, modified potato starch, sodium phosphate, potassium chloride, salt, maltodextrin, yeast extract, flavors, natural flavors, dextrose, caramelized sugar, paprika, vinegar solids, paprika extract, chicken broth. Contains soy.

    So 50% does sound excessive but perhaps soy concentrate & potato starch expands when the water is added to it meaning its volume is significantly more than the 2% listed above as dry ingredients.

  13. How do you know it didn't have a connection? Handheld devices can talk remotely to a base station at the counter in the restaurant. It would either dial up on demand over a telephone line or it would be connected over a data network. Even a restaurant on a mountain can get a network - probably easier than some other places since it's probably line of sight with a mast.

  14. As opposed to Europe, where the European chipped card could work in a place with no phone reception and no network access, the balance would be kept on the card, and the balance would later be reconciled in a central ledger at the end of the day, or at the end of the week (I'm not sure which). But this of course made the card super fast to use.

    I haven't seen any chip and pin device in Europe that DOESN'T require an authentication / authorization step. If it's allowed at all it would only be on small transactions - train tickets, snacks etc. The same is true for contactless transactions which don't require authentication on small payments but will still authorise payment usually by asking a server.

    It also doesn't make the process any slower in my experience than paying by swipe. If chip and pin is slow in the US it's probably more to do with people being unfamiliar with the process, inconsistencies between different stores / banks, or people forgetting their pin etc.

    You can run X on Windows too. Can I get FVWM to manage the windows that aren't in X?

    That's a pretty stupid question. The answer is yes assuming you have a remote client for whatever it is you're trying to work with.

    So tell me, how do I get FVWM to manage a Wayland window (I actually know the answer. Do you?).

    That's also a pretty stupid question. Why do you need to run Wayland at all if you're happy with X and some antiquated desktop environment?

    No it isn't. Many, many, MANY people have said the same things about X. Unless you can provide some serious arguments to back it up, you're full of crap.

    The multitude of ways it is broken have been written about in detail by people who've had to write extensions to work around the brokenness.

    You don't lose the "rich variety". You can fire up X if you like, even run X over Wayland. There's no need for the local desktop to suffer to run X though and X absolutely is horribly broken in a multitude of ways that no amount of extensions would have fixed.

    Yes complex system. Hydrogen has to be stored at enormous pressure which means bulky carbon reinforced tanks with safety release valves and valves in order to charge them at immense pressure. And the fuel is hideously expensive. And the fuel cell is enormous. And you need some batteries and regenerative braking systems to smooth out power flow. And massive air intakes to suck oxygen in at speed but which conversely affect vehicle efficiency. And enormous, massive pressurized hydrogen tanks along each route to store the fuel, and cryogenically pressurized trucks supplying the hydrogen.

    I guess it's impressive that they got a truck to move on hydrogen. It isn't a feasible system though. If they want to power trucks from a fuel cell then ethanol makes far more sense as a fuel source.

    Europe has mandated that all charge stations must support CCS type 2 and accept common forms of payment and charge customers on a non-discriminatory basis. Even Tesla in Europe will be required to comply with so I don't see that DRM is implicit to charging networks.

    It just requires the US and other regions to grow a pair and mandate standards that vehicles must comply with. CCS type 1 would be the natural choice and it would mean the likes of the proprietary Tesla charger (which Tesla doesn't even use in Europe) and the craptastic chademo will fall away over time.

    Pledging to eliminate all ICE cars by 2050 is such a far off claim as to be meaningless. And if they're replacing them with vehicles which derive their fuel from the same fossil fuels then its doubly so.

    Hydrogen is just a dumb means to power vehicles. It's very hard to transport, very hard to contain, incredibly flammable, very hard to produce and all round just a terrible idea. Personally I think fuel cells have potential but only when they use ethanol as their input. Ethanol fuel cells still use hydrogen but it's way easier to transport and store and it can be produced from biomass making it almost carbon neutral. Ethanol is also a common fuel in places like Brazil and trials of fuel cells using it are already ongoing there.

    Toyota really isn't going to get anywhere with hydrogen. It's a white elephant.

    Uber is more like Groupon. It's a service company with a dubious business model, a deteriorating reputation, an overhyped market valuation and a strong likelihood that it could come crashing down at any moment.
