Hi! It looks like you're working on a marketing strategy for a product nowhere near release! Would you like help?

Sam Jelfs

For me it is in the gym / out running at lunch time that the solution comes to mind. The trick is still being able to remember it when you get back to your desk...

And many a pint i've been sunk in each of them, or rather more often in the Vaults bar. Though not for some time now i'm afraid.

The classic line is "obvious to one skilled in the art" - Basically, can someone who knows about this field have made this same invention with little effort, not just obvious to the man on the street.

Re: Reminds me of ...

Some years ago when I was applying for university places my 6th form had recently installed a new content filter, which would be fine if it didn't block the websites of universities such as Sussex, Essex, middlesex and the like.

Wearable hybrids prove the bloated smartwatch is one of Silly Valley's biggest mistakes

Re: Er, seemsd to have missed....

I think the Fenix 5+ is aimed at a very different market than things like the ticwatch though. I have an older fenix3, and when it finally dies on me the 5+ will be the first choice I think (depending on what they have brought out by then, or if suunto ever make something decent)

Re: I can think of lots of uses for a smart watch...

I use a GPS tracker for a number of reasons - in training I use it to monitor my effort level (say some days I want to train at a specific level, esp forcing myself to run slower than I normally would), and also to quantify improvements over time, when I run the same route. But more importantly the main reason I bought the device I did was for navigation when out trail running, much easier having a device tell you which direction to run than having to read a map.

Seen as I have a "smart" device (and I'm not sure a garmin sportswatch really compares in functionality to something like an iDevice, but thats another matter), I use it. I bought it for running a few specific events, but why not use it for the rest of the runs?

Tell the public how much our tram tickets cost? Are you mad?

Sam Jelfs

Of course, it's why our train service here in the Netherlands is fast, on time, and (comparatively) cheap :D

For those of interested in the Antikythera, or machining, or general geeky-ness, I suggest checking out Clicksping on you tube, who is making a replica in his home machine shop.

OK... Red wire or black... *Clickety* You've emailed the schematic? Yes, got it! It's opening. And... WHAT? NO!

Re: Wi-Fi

I have 2 APs in the house, or rather one in the house that is also the modem / TV box, and one in the garage. Yet I still have to run a fixed cable to my OHs office on the 2nd floor because the signal is so poor through the precast concrete building. I can't get mobile phone signal in the house, I have to go outside if I want a reliable voice call...

Devonians try to drive Dartmoor whisky plan onto rocks

Strictly speaking distilleries don't have pagodas, they have a "Doig's Ventilator", or a cupola.

IoT worm can hack Philips Hue lightbulbs, spread across cities

Sam Jelfs

Not just Philips...

Its worth noting the authors write in their conclusion that "The main problem is in

the insecure design of the ZLL [ZigBee Light Link] standard itself", yes the attack was possible due to a leaked key in the Philips implementation, but the underlying standard is poor to start with, and there are some 1000+ ZigBee certified devices on the market from various makers.

Sound-mufflers chuck acoustic sleep blanket at the noise-plagued

Sam Jelfs

This has nothing to do with noise cancellation as in Bose headphones - it merely adds more noise to mask out the background noise. In effect just giving a constant, but higher level sound environment. Constant noise is less disruptive for sleep.

A few points...

The car didn't catch fire, some batteries that had been ejected did.

The occupant was already deceased.

The issue was with how to remove the body from the car / the car from the road, whilst making sure there was no risk of electrocution to the fire brigade, can't say I blame the fire service for being cautious given the maount of damage and chance of other stuff shorting out...

Re: TROPPUS TI

Back around 2001/2002 I was a student in the 6th form trying to apply for universities... UCAS applications had to be done on the school computer system using some custom software, just a shame the network firewall as also set up to block any site with the word 'sex' in it... Want to study at middlesex university, sussex university, et al, tough, can't look at their websites. (not necessarily a bad thing mind ;) )

British car parks start reading number plates

Sam Jelfs

Another good reason for driving a classic...

One of my cars is old enough to run silver-on-black plates front and back... never had an ANPR system be able to read the plates yet. My other car has dutch plates on it, again, UK car parks get very confused by the dashes in it.

Boffin quests for, finds 'earphone Holy Grail'

but on the other hand they will make you deaf...

Ambrose and colleagues presented a paper on these headphones at the AES 130th convention in London this weekend[1]. At the same conference they also gave a paper on the dangers of reproducing sound in a closed ear canal, and how it can cause serious damage, as well as causing timpanic membrane excursions in the order of 1000 times greater than would normally be seen[2]...

So yes, they have created a nice piece of tech that can easily block out back ground noises (and what isn't mentioned is that the greater the background noise, the greater the inflation of the envelope, so the greater the isolation), but at the same time they have also said that blocking the ear drum is bad....

@paul_murphy - the whole point being that you wont need noise cancellation if you can get a good enough seal in the ear canal so as to block out back ground noise... noise cancellation is for headphones or poorly isolating earphones... as to the cable, they could theoretically be wireless / bluetooth, but then you have to add in some bulky battery / processor unit as well as some form of interconnect between in-ear drivers and said unit... personally, that would annoy me more than having a cable (but not as much as having too short a cable that wont comfortably reach the device in my pocket....)

@Edwin

I didn't realise sheetrock was a Victorian product... one would assume a victorian house to be built from fairly sturdy brick walls with no cavity and thick timber and joist floors... all the victorian places i've lived in around the UK have been built without a bit of dry wall / sheetrock anywhere.
