Smartwatch owners love their calorie-counting gadgets, but they are verrry expensive

Patrick Moody

I have a smart-watch but not for the fitness features at all.

My TicWatch Pro runs on Wear OS (formerly Android wear) which means it can support the Xdrip+ watch-face that displays my glucose readings from my Freestyle Libre sensor, which are collected via an NFC-to-bluetooth transmitter stuck over the top. In theory, it can do this without needing my phone to be nearby, though in practise it's actually pretty flaky for this. Nonetheless, being able to see my latest glucose readings at the flick of my wrist rather than having to use my phone is really helpful. Especially while I'm driving since any interaction with the phone while behind the wheel is dubious if not outright illegal in most circumstances.

If it weren't for this, I wouldn't be bothering with a smart-watch as I rarely ever use any of the other features. As someone who takes his watch off overnight anyway, popping it onto its charger alongside my phone is no big deal, so the just over a day battery life isn't much of a concern.

Re: "Availability of several products pushed out to 2026"

Perhaps they meant that the products were guaranteed to remain available (not to be discontinued) until at least 2026.

Blinking cursor devours CPU cycles in Visual Studio Code editor

Re: Rule #1 for the user-facing components development

I think the developer should have access to all the computing horsepower he/she desires (within the employer's budget) but that testing/debugging should be done in a deliberately crippled virtual machine. This way the actual development tools will perform well on the high spec workstation, but the application produced can be seen to work well enough on a low spec end-user's machine if it does so in the low-end virtual machine instance.

Weight, what? The perfect kilogram is nearly in Planck's grasp

Patrick Moody

Re: Heavy science

The kilogram(kg) is not a measure of weight. The Newton(N) is.

"...yet is presently defined by a weight."

The weight (object) you refer to has a mass of exactly one kilogram, since it is the reference for that. It will still have that same mass, wherever it happens to be.

On Earth's surface, the weight (force of gravity) of a weight (object) with a mass of 1kg will be approximately 9.81N give-or-take depending where and when you measure it.

11 MILLION VW cars used Dieselgate cheatware – what the clutch, Volkswagen?

Re: Goodbye DISEASEel!!

A/C's comment was specifically about diesel, not about advances in modern medical science. The fact still stands that the real diesel particulate and NOx emissions are significantly higher than they are supposed to be and those are well known to be significantly detrimental to health.

Instead of looking at how far medical science has improved life expectancy in spite of the surge in production of dirty diesels over the last 20 years, we should be wondering how much better things could have been if they stayed at their pre government-supported level (see http://www.enveurope.com/content/25/1/15) which would likely have been much more similar to the US (see http://www.bbc.co.uk/news/world-us-canada-34329596). We should also be thinking seriously about how we can move away from them again, in favour of the less damaging alternatives.

Before all the diesel enthusiasts down-vote me in their dozens, perhaps you could think about why it is that you are a diesel enthusiast. Is it because they are genuinely a better proposition for passenger transport than all of the alternatives, or just because they're cheaper to run (almost entirely because of the government sponsored market distortion)?

Patrick Moody

Re: I can understand why they did it.

Scrappage wasn't compulsory. It was just intended as an encouragement. Someone with an old car who wanted to replace it but was £2000 short for the new one they wanted to trade it in for, suddenly found themselves able to afford that trade. The market was distorted, and many perfectly-good old cars that could and should have been maintained were scrapped.

As we are now discovering just how perfectly-good the diesel cars aren't, it would be appropriate to do the same. Since you say you're not prepared to replace with new, even if you did have £2000 help you do so, you wouldn't directly be a target for this, but I don't really see how that would mean that you'd lose out in any way. Everything stays the same for you until the next time you change your car, by which time I'd hope that diesel cars make up a significantly smaller part of the market.

To really speed things up I'd suggest they get rid of the minimum ownership period for the old car (in the last scheme you had to have been the registered keeper of the old car for at least 1 year before the trade). This way it would encourage a trade in old diesels (perhaps including yours) so that someone could buy a 2nd hand diesel for <£2000 and immediately trade it in through scrappage to more than make back what they spent. Old diesels in that bracket become more valuable rather than less, but only for the ultimate purpose of getting rid of them. Everybody wins!

Patrick Moody

Re: I can understand why they did it.

MJI - "I think we are seeing the beginning of the end for Diesel cars."

and not a moment too soon.

Perhaps the UK govt. could reintroduce the ridiculous scrappage scheme that they used a few years ago to encourage people to waste money on brand new cars instead of maintaining their >=10 year old existing cars.

This time it could be applied only to diesel cars (of any age) and used to offset the cost of buying a modern petrol car to replace it. The public health benefit would be enormous.

Patrick Moody

Re: Well, let's summarise this.

A/C - "If this is commonplace, then what? Stop selling cars altogether? Recall the lot and walk to work?"

The answer is stop selling diesel cars altogether. Ask any cyclist who has ever followed a diesel car whether they believe that the emissions are really as clean, or even comparable to the emissions of a similar petrol-powered car. The falsified test figures suggest that they are, but this discovery just confirms what was obvious all along.

Re: I'm not a telco engineer but...

Surely the units boil down to bits per cycle. My interpretation being that as 1 Hertz means 1 cycle per second:

5.7 bits per second per Hertz


5.7 (bits/sec)/(cycles/sec)


5.7 bits/cycle

Essentially they're talking about the bit-rate, versus the light-wave frequency (or cycle-rate) so the 2 rates per second cancel each other out leaving only the bits and the cycles. If you used a higher frequency carrier signal, you'd get a higher bit-rate and the impressive thing is increasing the bit-rate without needing to increase the carrier signal.

Please feel free to correct me if I'm wrong.

Sleepy Ofcom glances at Internet of Things, rolls over, takes nap

"proved beyond doubt there was no user demand for ADSL to the home without a landline number." Except for all the Under 40s who couldn't possibly care less about having a landline number and would jump at the chance to reduce their line rental costs if that were a side-effect of ditching it.

I'm quite certain that as time goes by, the proportion of the population who actually want a landline number (almost exclusively the older generations) will continue it's relentless approach zero. For the rest of us it is an unloved side-effect of getting a wired connection to the internet.

Ford dumps Windows for QNX in new in-car entertainment unit

Touch-screen enthusiast down-vote magnet alert.

How much of the time during that video did the driver have their attention on what was happening outside the car? I saw precisely none. Would you expect to have to be parked to carry out all the operations he did? Doubtful.

If the EU were going to introduce any useful regulations for cars, it would be to ban the use of touch-screens in moving vehicles. Frankly, I think these kind of systems are a serious danger to other road-users due to the level of attention the driver must pay to the screen in order to interact with it.

As much as possible, the controls in a car should be used by touch alone so the driver's attention can stay focussed on what's going on outside the car, where it should be. This would mean no screens (for the driver - for passengers there's no problem), and only switches, rotary dials or sliders for controls, all of which you can tell the state of just by touch.

My 2003 Mondeo doesn't have a touch-screen, but it does have a ridiculous heater control which has 8 momentary-push buttons and an LCD. You can't tell what it's set to without turning it on because the LCD stays off otherwise. You have to look at the LCD for any feedback. It requires repeated presses of the buttons to adjust the fan speed or the temperature, along with further looking at the LCD to see if you've set it where you want to. It's far too distracting for something that was so elegantly and simply handled in most previous iterations. If it consisted of 3 dials like on a typical earlier-generation car I would be able to tell what its set to by feel, and I could adjust the fan speed or temperature instantaneously without even needing to glance at it to know I'd done what I intended. I'm quite happy with the rest of the car, but I think the designers at Ford should be ashamed of themselves for this aspect, and it appears that since then they've carried on even further in this lunatic direction.

Musicians sue UK.gov over 'zero pay' copyright fix

Re: Compensation has already been paid

Nonsense. The PRS licence in the workplace would only be fair if it wasn't also charged for just listening to a radio. The performers are already compensated by the radio station from the funds they receive from their advertisers and the listeners in the workplace, by being exposed to those ads, are effectively paying for it that way. The more people listen, the more exposure for the adverts, the more those adverts are worth and the more a radio station can charge for them by having higher listener numbers and this increase is presumably reflected in the fees paid to the record companies.

The only situation I can think of where it would be fair for an employer to have to pay PRS is if the employer has its own juke-box or other method of playing music that was purchased as a CD (or mp3 or whatever). Since the CD price was based on a single person's use, and the employer is playing it to many people and there's no radio-station collecting ad-revenue in line with the number of people listening to pass it on to the artist, this is the only situation where I think an argument can be made for the artist having lost out.

Ford's B-Max: Fiesta-based runaround that goes THUNK

Patrick Moody


From what I've seen, Ford abandoned intuitive gadget controls (the ones you can use without having to look down at them) sometime before 2003.


My late 2003 Mondeo has an awful digital display for it's air-con/fan controls which you have to look at to work out what you're doing with it. It's crap in several ways:

1 - You can't tell how strong the fan will be, how hot the air will be or which vents will be active when you turn it on until you do, because the LCD only turns on when you turn the fans on. Unlike conventional controls which you can check on by feeling the position of the rotary switches and sliders.

2 - Once it is switched on, you still have to look at it to do absolutely anything. This is a major bug-bear for me.

3 - To adjust the heat requires repeated presses of the temperature adjustment push-button, along with repeated glances at the display to see if it's got to the level you want it at.

4 - The same applies to the fan strength. You'd think that this one you could at least get feedback on by feeling the air-flow, but as there's a long delay between setting the fan strength and it actually having any effect even that isn't very practical.


If you don't want to risk getting prosecuted for driving without due care and attention you should park before adjusting the heater on your Ford car! Granted that's not much of a risk, though, since there aren't any real police on the roads to observe you doing that these days anyway.

Who wants to be a millionaire? Not so fast, Visa tells wannabe pay-by-bonk thieves

"Contactless is about convenience at the expense of some of the security controls." but it's only convenient when you only have one (including Oyster cards for London Transport). As soon as there's more than one in your wallet, it becomes equally inconvenient to chip and pin, as you still have to remove the card from the wallet to make sure you're using the right one.

At that point the only remaining advantage is not having to key in the PIN number - something that could easily have been done via the existing chip-and-PIN system, simply modifying it not to require a PIN for purchases less than £20. Modifying the chip-and-PIN system this way wouldn't have introduced the security vulnerabilities of contact-less, or the inconvenience of card-clash with Oyster.

Re: Schol Reform

He also said:

"change it from 9-3:15 (or whatever it is right now) to 8 - 5."

I'd estimate that you get 5 hours lessons from a 9-3:15 day and at least 7 hours from an 8-5 day, which would more than make up for the difference. I think the anonymous coward actually made some pretty good suggestions.

Galaxy S4 phondleslab selling like lukewarm cakes, analysts reckon

Patrick Moody

I said all the same things about my Galaxy S2 when I got it less than 2 years ago. A couple of Android upgrades later and I find myself starting to wonder if I should look for something faster when my contract expires.

On the other hand, the main problem for me is I like the size of my S2 but don't like the 1-day-only battery life, and all the new flagship phones are much bigger and with equally poor endurance. Nobody seems to have really addressed that yet either. I think I might just stick with it on a cheaper rolling monthly contract until someone does.

Bitcoin now accepted in London pub. In Hack-ney, of course

Patrick Moody

Re: Cyber tax

Perhaps the pub loans the customer the price of a pint in pounds, interest free for a few milliseconds. The customer immediately uses that money to buy the pint and so the pub pays it's VAT bill and whatever taxes based on this transaction as normal. The pub then pays the same money back to the customer for a currency exchange, which the customer uses to settle his debt. The customer then transfers the appropriate amount of BitCoin to the pub to complete the currency exchange transaction.

Re: Or...

I should have said, none of that is gospel. It's just my understanding of the situation.

Patrick Moody

Re: Or...

There will be heavy fines for motorcyclists, cyclists, pedestrians, horses, cats, dogs, mice, rats, flies or anything else spotted on the stolen tarmac (Olympic Lanes). You'll need to be extra careful you don't have a wheel stray over the line while you're filtering along past all the other motorists stuck in the inevitable gridlock. The rules on bus lanes are a different issue. Even there it's inconsistent. Motorbikes are allowed on red route bus lanes (managed by TFL) but it's up to the local borough councils whether or not you're allowed in on the bus lanes in their patches.

Assuming you manage to get where you're going without being fined into bankruptcy, do you think you'll still be able to find somewhere to park?

As a fellow biker, this stuff irritates me too.

Re: "Two words: Power consumption."

Device selection is probably lacking because practically no-one is buying them. As a result there's little motivation for companies to produce more devices. If you talk to an average non-IT person, the kind of person who you would need to be prepared to spend money on these things in order for them to become popular, chances are they'll think of home-automation as something difficult and nerdy and not something they'll want to try for themselves.

Home computer networking by comparison is relatively easy. If they don't know how to do it themselves, they definitely know someone who does.

When you start telling them about the 3 standards that they have to choose between for the new network they will have in their house they'll almost certainly switch off from your conversation and start looking for someone else to talk to.

My point still remains that until it both is and is seen to be trivially easy to set up and maintain these things it'll never become mainstream and as long as it's not mainstream, the market won't be big enough to encourage device makers to improve their selection.

Patrick Moody

Re: "Two words: Power consumption."

...and yet neither of these replies to my comment address my main point: People simply don't want to be bothered with setting up an entire new network if they don't already have it.

Very few people already have it (the exceptions to my previous sentence). The barrier to entry is still way too high for this sort of thing to become popular and I'd argue it will continue to be too high until it is practically zero. One simple way to make it practically zero would be to use the already existing wireless infrastructure in most people's homes, WiFi, instead of expecting them to install and maintain another one.

I'm no Apple fan but I bet if Apple did it it would be dead simple. Apple don't do it. It isn't.

I look forward to being proved wrong on this. I think it's a shame that home automation hasn't taken off yet.

Patrick Moody


I don't understand why you wouldn't want these things just to use your WiFi network directly. By designing it with WiFi instead of Zigbee, the customer need only buy the shiny new fish-tank filter and absolutely nothing else. That is, of course, making the assumption that anyone whoi would be interested in the device likely already has WiFi in their home. Well enough designed, it should be absolutely trivial to install it and get it talking via email.

Make it with ZigBee but no WiFi and it might use less power (who cares? it's plugged into mains, not battery powered) and your customer must now buy another ZigBee device to act as a controller, then configure that controller device to connect both to the fish-tank filter and your home internet connection and then set up the rules for it to email you at the appropriate time. That's way more faff than most people are prepared to tolerate and an additional expense. Someone who already has a ZigBee network at home (If I had no digits at all I could still use them to count the number of people I know who this applies to) might be pleased to have an opportunity to do this. Normal people won't.

I think this is why home automation won't take off. The barrier to entry needs to be made so low as to be imperceptible first. I don't think we're anywhere near that point now.

Letting Nokia off for Microsoft's imposed limitations

"...Still, Nokia’s not to blame here." They absolutely are to blame for any and all shortcomings of the phones they produce. It was Nokia's choice to employ an ex-Microsoftie. It was his (highly predictable) choice to decide to use Microsoft's phone OS for all future Nokia smart-phones. Being subject to Microsoft's demands are a consequence of these choices which they made themselves.

Ofcom boss warns of low interest in 'superfast' broadband

Patrick Moody


Re-read the post you were replying to and I think you'll realise that he's not moaning that his cheap service isn't as good. He's actually saying he's perfectly happy with it and doesn't see the point in paying any more for a difference in service that he would rarely ever notice. I suspect that is a very common viewpoint, and there's no such thing as a killer app for broadband (over and above the bandwidth needed for iPlayer) that I'm aware of.

If you can't rely on having very high bandwidth all the time (especially during peak-periods which coincide with the time when the majority of people are going to want it) you wont want to rely on any service(killer app?) that depends on it. This is a situation that won't change for a very long time I suspect.
