  1. Re:Pagers vs SMS on The UK's Health Service Told To Ditch 'Outdated' Pagers (bbc.com) · · Score: 1

    In this case the pager system is unlikely to get overloaded when there's a crisis or some other event where everyone is on their mobile phones.

    The question isn't one of paging vs SMS. There are many alternatives. If anything they would probably switch to SDS messages over TETRA which is what the rest of the UK Emergency services already use via the Airwave service. But even if they did use the public infrastructure it doesn't mean doom and gloom. 3GPP Release 13 includes message and device level prioritization including device preemption. It's something we tested when we were looking to LTE to replace 2-way radio infrastructure and a completely overloaded tower sending out nothing but busy signals will happily boot off those pesky members of the public in order to deliver your high priority message and give you service.

    If they are complaining about the cost of running pagers then they will not at all be happy with the cost of using ASTRO P25, though in the UK they'd be using the Airwave TETRA system.

  3. Re:Here is why pagers are so important on The UK's Health Service Told To Ditch 'Outdated' Pagers (bbc.com) · · Score: 1

    They should keep the pagers, absolutely. The reason is this:

    Pagers use slow transmission protocols that do not need a huge S/N to be properly decoded.

    That is not a reason to keep using pagers. In fact every emergency service messaging protocol achieves what you described, including messaging based systems that run on the Airwave network or the proposed public safety LTE extensions.

    It would be a blunder of gargantuan proportions to stop using pagers for critical messaging.

    That blunder along with your doom scenario hasn't played out in other parts of the world where pagers have been abolished. What would be a real blunder is when the pager network dies as the hardware is well and truly beyond end of life. Keeping old radio equipment operational is an exercise in endless and increasingly expensive frustration.

  4. the motor (magnet circuit and voice coil) is the transducer

    definitely.

    and the cone is the amplifier

    arguably.

    Cut the cone out of an old loudspeaker. Notice it still makes sound but at a greatly reduced volume and efficiency?

    in this case is what changes electrical energy into pressure

    Like the the magnetic coil that applies the force to make something move?

    and that includes the radiating surface

    That is your own definition. In fact I can't find the radiating surface mentioned in Wikipedia or in my textbook.

    since the pressure generated is proportional to the radiating surface

    So you're saying a bigger radiating surface would "amplify" the pressure?

    and the radiating surface is required for the transformation to take place

    Again hold up one of those surface transducers in the air and hear that wonderful transformation having already taken place. Likewise cut the cone out of a speaker (but you need to point the speaker vertically) and listen to that transformation still making sound.

    The word transducer doesn't include mention of volume or quality in its definition which makes it independent of its radiating surface. The word amplifier on the other hand ... well you get the point.

    I'm actually quite surprised they went to the expense of powered breaks.

    You can do the same thing with solenoid activated latch on a traditional mechanical hand break.

    You're surprised they went to the expense of an electric brake (which can use up to no additional parts depending on the motor controller) but instead you propose a far more expensive mechanism?

    Follow the money, they went with powered brakes precisely because alternatives are an additional expense.

  6. I believe you meant screen as audio transducer... At least it keeps the headphone jack!

    I think amplifier could be perfectly acceptable use of the word here. The transducer is what would be acting on the back of the screen, and the shape of the screen amplifies the air pressure waves which would otherwise be tiny without the available surface area, but would none the less still be air pressure waves.

    I wouldn't be surprised if they even built prototypes and evaluated them internally. That fact that Apple has not even hinted at such a critter probably means that they decided that the product wouldn't be a big hit.

    You have to remember Apple is a very new entrant into the market of the technology that enables foldable screens. The company forever shunned OLED while all their competitors adopted it.

    There's no doubt Apple are watching this space closely, but it's been very clear over the past 5 years that Apple has become very much a careful follower than a technology leader so their silence may not be an indication that they don't think it's a hit, it may be more that they aren't convinced that the technology is actually ready for market yet.

    Wait what? No sorry a bunch of people wanting to work part time for reduced pay is not the civilised end-result of automation. This is even temporary so workers aren't able to elect to do this beyond 2 years. This was nothing more than a work-life balance related negotiation tactic to not offer the original promised pay increases. It's great virtue signalling because we all know that people desperate for a 6.8% pay increase will jump at the idea of a 27% reduction in pay.

    They also took careful aim at their foot there. The logical end game of their shorter weeks which the company can't deny is for a company to automate their work. Expect these people to ultimately lose their jobs when it becomes clear that they weren't providing 37 hours of value in the first place.

    Your industrial knowledge points you towards safety but the standard you are pointing to is about active safety interlocking for mitigating an event. If you're looking at a system whereby failure of control automatically leads to an incident you're working in the continuous operation realm, the standards for SIL in this case are typically applied where failure will result in multiple millions of dollars of damage along with killing multiple people. Additionally to apply SIL need to have a determined safe state ... in this case the safe state is applying the brakes and applying the SIL standards would not prevent people from kissing the pavement.

    You don't need to point to this kind of standard to achieve a safe system. Instead another industrial principle should be applied. Rather than applying safety standards for the mitigation of events, the principles of "Inherently Safer Design" should apply. e.g. Other hire companies: The system which locks the wheel electronically on for example O-bikes is 100% decoupled from the braking system while under normal operation and requires a person to actively push a pin through the wheel against the force of a spring, the result of which reports back to the mobile phone that the hiring period has finished.

    Huh, what are you blathering about? For gaming, 1080 means 1080p,

    Thanks for telling us you're not a gamer. Any gamer would know the distinction between resolution, and resolution at a locked frame rate. The OP said no serious gamer games at 1080p@60Hz. You countered saying 1080p was popular. Yet it is. You included a metric fuckton of non-serious gamers in your worthless statistics.

    TL;DR "clearly the RX 580 is the better card in more of the games that we've tested

Man the "Xbox play on my 30fps TV" generation really has destroyed what it means to play games if these numbnuts think this is even remotely an appropriate card for a "gamer".

    Not only does the 580 outperform its closest competitor the 1060

    And by their own results the 580 is frequently out performed in raw framerate and almost universally outperformed in frame time variance.

    it sells for less and has way more VRAM

    Yeah but NVIDIA has a green logo, which is just as relevant of a metric since you're ignoring performance.

    Frankly, it's hard to believe that Nvidia has the gall to sell a midrange card with 3GB, but they do.

    ... Man you're just going down a whirlwind of stupidity right now. The only 3GB NVIDIA card currently manufactured is the entry level 1050. Their midrange 3GB card was discontinued early last year when they exclusively started shipping 6GB cards and upgraded their RAM to GDDR5X in the process.

    Could be just the card for you.

    I have one. It's a great card for a non gaming PC. But since you don't know what the definition of gaming is, ... well come back when you're running 1080TIs in SLI watercooled. Then you too can play with the big boys.
