AI of the needle: Here's how neural networks could detect nighttime low blood-sugar levels using your heart beat

Re: A bit out of date

The DVLA now accept the glucose measurements from the Libre as suitable for confirming your safe to drive, unless you are a PSV or HGV driver.

This sounds like an AI solution looking for it's problem... rather than a problem that needs to be solved.

As a long term diabetic I now only use the traditional finger prick technique a couple of times a week at most. The rest of the time I wear a patch that last 2 weeks, that takes a measurement and stores it in it's memory every few minutes, scan the patch with an NFC smartphone or it's dedicated reader 4-5 times throughout a day and I get graphs of my blood glucose levels over the whole 24 hour period.

I find keeping track of my blood glucose neither annoying or painful, it's just a fact of life. I suspect the faff of effectivley rigging myself up to an ECG that can take accurate enough readings would be considerably more effort.

I luckily dont worry too much about hypo's but, for those that do there are similar solutions that can continually monitor your blood glucose 24 hours a day, and alert you if your in danger, they're currently expensive but they work, are available now, in the UK funded by the NHS for those that really do need them.

Re: Improbable

And that's why the first thing my A Level Physics tutor told me to forget everything I had learnt at GCSE because it was either a lie or an over simplification.

I was then told exactly the same thing at degree level, seems a perverse way to teach to simplify things to the point they are factually incorrect and then have to "correct" that knowledge at a later date.

I don't think that I was that unusual as a 15-16 year old that I could understand that there would be shades of grey in the answer to a question. The fact that "Few kids are interested in why it's changed" is wrong on many levels;

a) The voltage has never changed, just the way it's described and for political reasons.

b) Your implying that we shouldn't teach kids anything they're not interested in

Using the new description of 230v +10% -6% or the old one of 240v +/-6%. Gives a range of valid answers and in both cases either 230v or 240v is a perfectly correct answer.

A system that marks a student down when they have given a perfectly correct answer just because they haven't given the answer the examiner was expecting is broken and not fit for purpose.

Reminds me of the quote from my boss in my first true engineering job, "Those that can do, those that can't teach...."

TalkTalk incident management: A timeline

Passwords not revealed

TalkTalk have in one of their latest statements claimed that passwords haven't been revealed due to this hack, but they've just sent a message to their business customers saying that they have changed our account login password and that I should follow the "forgot password" link on their logon page, answer our security questions and then change the password to something known.

This begs a couple of questions;

a) Is the "passwords not compromised" position a lie? Otherwise why the reset process?

b) Where the security questions in the same public facing database and therefore likely to also be compromised?

TalkTalk Business also affected

Just had my email from TalkTalk business which has confirmed that they-re also affected. Unfortunately they've just copy pasted the email they sent to their residential customers, offering the same hopeless advice.

Free credit checking services like Noddle don't allow you to monitor your businesses credit file so don't help. Its TalkTalks incompetence that has allowed this to happen therefore I want to know how they plan to implement my ability for me to monitor my businesses credit file without incurring additional cost.

Like others I also want to know if I can cancel my contract without penalty as I no longer trust their competence. I also want to know how I can go about getting my details deleted from their systems permanently.

BT: Let us scrap ordinary phone lines. You've all got great internet, right?

So long as BT can promise that they'll have engineers who understand IP networks well enough to fix it when it goes wrong, the other issues around power outages etc aren't insurmountable.

We've had an ongoing fault for 3 months, on a FTTC connection where there's constant packet loss that varies between 10% and 80%, which makes the connection all but unusable. We've had 5 Engineers every one of them has come, done a pair quality test and can see sync to the cabinet at 78/19 and close s the job as no fault found.

The last engineer to come observed the packet loss and agreed that there was something wrong, but then explained that Openreach only provide the copper path and that as far as they where concerned the fault lies with either the ISP or BT Wholesale and that he had no alternative but to close the job as no fault found.

Manufacturers slam UK.gov: 'High speed broadband' rollout is too slow

Superfast Cymru

I run a busines in one of the largest towns in what is to be honest a very rural area of Mid Wales where superfast broadband is being deliverd by Superfast Cymru, a joint BT / Welsh Government project. There was much fanfare when we where told that fibre would be available in July of this year, then September. The rollout started an they've done all the cabinets that feed the residential estates, but have completley missed out the two cabinets that serve the town centre and have now moved onto small outlying villages (most of them less than 100 homes).

On making enquiries I keep being told that our cabinets are on the rollout plan, but that they cant tell me when the cabinets are to be upgraded, this month, next month, next year, 2017. I dont really care when, but would really like some estimate so that we can make plans for the businesses future development. I dont want to waste money having EFM/LL fitted only to discover a cheaper FTTC product that would suit us just as well is available the next month.

Is it really a hard concept for BT Openreach and their "delivery partners" to understand that people, especially businesses need to plan for the future. Its my belief that Openreach are deliberatley missing cabinets with high numbers of business users to prop up the sales of EFM / Leased Line products from BT Wholesale.

Freeview's rumoured '£100m YouView killer' is real – and it's yet another digital TV thing

Strategy

Rather than being a vanity project as some have suggested, perhaps it's part of a longer term strategic switch from traditional broadcast to a fully IPTV based service in the future.

The mobile operators, Ofcom and DCMS are already proposing that Freeview move from the 700MHz band by 2018, and there is already talk of taking away the 600MHz band by 2023. On a technical level freeview is already struggling in parts of the uk having lost the 800MHz band to 4G last year because transmitters in neighbouring areas are now causing interference.

From the broadcasters perspective switching off the terrestrial transmitters tomorrow would be a huge cost saving, the costs of broadcasting by satellite are significantly cheaper. IPTV where the end user foots the bill for the transmission costs (by paying their ISP for bandwith) is cheaper still.

What better way to test the system, than to use, free, self selecting, beta testers, who'll buy their own equipment.
