  1. Depends a lot on what applications access the data on Slashdot Asks: Do You Need To Properly Eject a USB Drive Before Yanking it Out? (daringfireball.net) · · Score: 1

    If your only use of the USB drive is to copy files to and from it, you're unlikely to remove it when it's still copying files, because there's usually some on-screen progress device.

    If you are using an application that done random writes to a file on the filesystem, such as the older Microsoft Office file formats, then you'll have the file at risk all the time the document is open, even if you've recently hit 'Save', because Microsoft Office writes a lot in the background, even when it's not 'saving'.

    The exact same problem happens when handling files on a network share when a VPN drops. If you forget to close the document before dropping the VPN, then the file's internal storage tables can become corrupt in a way that requires specialist recovery software to repair.

    This could have been one of the reasons why Microsoft Office changed their file formats.

  2. Re:Potential Debcale on UK Wants An Electric-Vehicle Charger In Every New Home (thedrive.com) · · Score: 3, Informative

    three-phase isn't actually 400V RMS between the phase and neutral, it's 400V RMS between phases.

    Most UK domestic properties aren't hooked up to all three phases of the grid. Typically, each house along a street will take a different phase from the grid, so my house would have about 240V from phase 1, my neighbour to my left is on phase 2, my neighbour to my right is phase 3.

    In the UK, the phase-to-neutral voltage is notionally 230V with a tolerance of -10% +6% but that only came in with international harmonisation, in reality, UK domestic properties tend to be about 240V, because that's what was designed into the grid before the international harmonisation. Having this harmonisation is good - it means that aside from a different connector, you can use an appliance bought in Ireland and use it in Russia.

  3. and completely automated.. on Companies Must Let Customers Cancel Subscriptions Online, California Law Says (cnet.com) · · Score: 2

    I remember back in the days of working for a dial-up ISP, I developed an on-line-cancellation process, to complement the online registration systems.
    Go to customer accounts web site.
    Pass the usual authentication credentials
    Click on cancel service.
    Choose which service you want to cancel
    Confirm.
    If the user is currently connected via that service, disconnect the session immediately, flag the service account closed on the authentication server, remove DNS entries, deny incoming email, remove associated web hosting, get the billing system to record the service closure and associated billing product pro-rated refund calculated, and if it was the last billable service on that account, the refund to go through automatically to their usual payment source.
    End-to-end, it would take minutes.
    If user is not currently connected via that service, it would require a human to vet authentication, and call them back to confirm.

    It was never deployed. DSL came along, and with it supplier contracts with a 12 month mininum contract term per customer line, which made the cancellation process tougher to automate.

    Which is why I never install a mobile phone app when there's no good reason for collecting any further information from me. Often, there's a perfectly functioning website, and you have far more control over what data you provide, and tracking functions from a browser - private browsing modes, adblock etc, than you do with a bespoke mobile phone application.
    I recently encountered some online shop, whose web site refused to give out any useful information about the products on offer, insisting that customers download their mobile phone app, which probably gathered far too much information than needed to perform any sales transaction. Net result to them was lost sales.

  7. Re:Engine bay on BMW Says Electric Car Mass Production Not Viable Until 2020 (reuters.com) · · Score: 2

    The Nissan Leaf fits CV joints to traditional wheels, half shafts, a differential, a fixed 10:1 reduction gearbox, the motor itself (single AC induction motor), the inverter (drive electronics / motor controller), the on-board AC to DC charger , as well as the normal electric power steering, 12V accessory battery, and climate control systems, into what normal cars call the engine bay. There's still plenty of space there, but I wouldn't call it empty space.
    It's a front-wheel drive car.

    A rear-wheel drive car like the BMW i3 has a similar arrangement, with the motor normally at the rear instead. The i3 also manages to shoehorn in space in the rear for a motorcycle-derived engine for the generator for the optional range extender, while having some cargo space in the front where traditional cars have an engine bay.

    Many electric vehicles with all-wheel drive (new Teslas, Mitsubishi Outlander PHEV) use two motors - one front and one rear, because that's simpler than having a transfer box and big heavy driveshafts, and gives more precise delivery of power without complicated drivetrain.

    Having the battery under the floorpan makes the weight distribution of electric vehicles really quite good in snow, even if they don't have all-wheel-drive.

    There are some four-wheel-drive, four-motor vehicles around, but none in mass production. The Audi Lunar Quattro is one.

  8. Geocoding quality on The Future of Free and Open-Source Maps (emacsen.net) · · Score: 1

    Geocoding requires two things:

    1. Accurate and complete data. It is well acknowledged that in many areas, full street addresses are not yet there in Openstreetmap, but you can geocode at street-level. I've had many cases where Google's geolocation for addresses is way out, and doesn't even give a warning that it's only managed a partial match on the geographic centre of the district.
    2. Context. Depending on your application, you may only be interested in the 'Station Road' nearest you. How's the geocoding server supposed to know if the client application doesn't give it a hint as to how the results should be ordered? Google's geocoder is likewise hopeless with giving relevant results if the client application doesn't give it a hint that you'd prefer a local result over a result from a different continent.

    Another reason to buy standard, uncrippled, unlocked phones separately from any airtime contract.
    Buy them on credit if you must. My airtime provider doesn't care much as to what handset I have, so long as my SIM will fit, and it will work on the frequency ranges and technical standards that their network uses.

    Insurance against a phone going missing in transit from the seller to the customer should not inconvenience the customer in any way, other than possibly acknowledging safe receipt of goods. If Verizon is worried about this, they should offer free unlocking immediately after their customer acknowledges safe receipt.

    Brake lights cause traffic jams. If you're on a motorway (freeway), never use your brake pedal except in an emergency. That's what engine braking (or regenerative braking on modern cars) is for. Keeping a steady speed, and only accelerating and decelerating slowly helps other drivers to match speed when merging, it also does wonders for fuel economy.

  12. Stick the panels on embankments instead on China Is Building a Solar Power Highway (electrek.co) · · Score: 1

    Ditto for railway lines. Panels under a road is a silly idea, but there's more than enough wasted space at the edge of most major roads, which are often on embankments or in cuttings. Let the panels at least approximately face the sun, don't cover them with traffic, tyre dust, and other assorted grit, then it might make physical sense, or even commercial sense.

  13. These speed calming measures work once.

    When a driver realises they are fake, they continue to drive at whatever speed they would have done previously.

    The problem that actual speed bumps cause is that people slow down for them. They then accelerate afterwards. With fossil-burning vehicles, this leads to pollution.
    What actually works to prevent speeding (and stop-stop bunching, and some pollution) is average speed cameras, and stretches of roads that are clearly signed as such.
    Either that, or actual police visibly doing traffic enforcement, but it seems they don't have the resources for that these days, so they let the computers do it with cameras.

    Another interesting method I've seen at controlling speed in an urban 20 mph zone is where the speed trap will immediately turn the next traffic lights to red if you speed. Stay under the speed limit, and you get smoother traffic flow. Drivers are more likely to stop for a red traffic lights to avoid a t-bone collision than drive below the speed limit.

    If Microsoft have a way of delivering correctly licensed Win32/Win64 packages to Windows users, with a single reliable, trusted update / patching mechanism, that they don't overcharge developers for then they may be onto a winner. Until then, Windows users are stuck with downloading from random sites on the internet, that may themselves be full of corrupt advertising links and malware. Until I see all the software I'd actually want to use on the Windows Store, the cut-down version of windows isn't going to cut it for me, and most Windows users.. Even in the education market.

  17. Phone on hire-purchase, airtime on monthly on Really, Why Are Smartphones Still Tied To Contracts? · · Score: 1

    Some providers are splitting out the cost of the handset from the airtime. You can buy the handset from them if you like - and they offer a hire-purchase agreement if it seems too much up-front (or just buy SIM-free, unlocked), and then the airtime contract can be pay-as-you-go or pay-monthly, which may or may not involve some minimum term. They can be bought at the same time, and the small print makes it clear that it's two contracts. The minimum term for airtime might get you some discount if you commit to staying with that service provider for a longer period. Personally, I bought my own smartphone nearly two years ago (it wasn't cheap), and just popped in a pay-as-you-go sim, with automatic top-up. I could get a better tariff that way.

    Yes, entirely possible. Routing will be a challenge when dealing with millions of fiddly small route entries. At the moment, the Internet routes at a very high level using BGP. The ISPs then internally know how to route their own customer allocations. Even when the route advertisements are for large allocations the routeing tables get very large indeed. If you start announcing routes for a single /32 (IPv4) to multiple peers or a /64 (IPv6), the amount of memory needed on the routers becomes rather enormous. Your typical cheap home router wouldn't have the capability. They typically have barely enough memory for a state table let alone worry about dynamic routeing. Of course, there's nothing to stop you (with permission) hooking into your neighbour's wifi as a client, and privately peering traffic with their public IP addresses. I have yet to see any router hardware or firmware that allows for that sort of thing out of the box with minimal configuration. Persuading your neighbours "upstream" links to offer routes to your network via their connection if yours went down is another matter entirely.
