Apple to return to 4 inch screen?


Credit: Macworld

Much discussion has been generated over the base-line-trend towards larger screen sizes in smartphones. At 5.3 inches, the original Samsung Galaxy Note, & more recently, the new, bigger iPhones have generated a furore.

If you find the new iPhones too big, you may just be in luck. Predictions of a new, 4 inch iPhone are all over the ‘Net:

Hotels at it again – application to FCC to start jamming personal WiFi – update

You may remember a post in October of this year about the Marriot chain being fined $600,000 after its hotel in Nashville, Tennessee was found guilty of blocking guests' mobile WiFi. Apparently the purpose was to encourage use of the Marriot’s own WiFi at between $250 & $1,000.

Now a group of hoteliers, including Hilton & Marriott, are asking the US Federal Communications Commission to grant permission for them to recommence disruption of guests personal WiFi. Claims include that personal Wifi can, “cause degraded service, insidious cyber-attacks & identity theft."

Taller, narrower tyres for your next car?


BMW i3 takes advantage of taller, narrower tyres
Credit: BMW/The Telegraph

Recently, a few trends in cars have been:
• wider tyres
• larger diameter wheels
• improved fuel efficiency

All other things being equal, & within reasonable limits, for each centimetre increase in tyre diameter, rolling resistance reduces by 1%. This happens because the tyre suffers less deformity in the contact patch (the part of the tyre in contact with the road) & sidewalls, as it rolls.

Increased tyre diameter is consistent with the other current trend toward improved fuel efficiency.

Odd man out in this equation is wider tyres, which increase rolling resistance & aerodynamic drag. Taken together, these two factors reduce fuel efficiency of a vehicle.

Wet weather performance of a tyre is substantially determined by it’s ability to displace water. A tyre which displaces more water, effectively drives on a drier road. As the tread rolls into contact with the road, it begins to displace water sideways, to be expelled from the sides of the contact patch.

A narrow tyre has a relatively long, narrow, contact patch. On a wet road, water has a shorter distance to travel to be expelled at the sides of the tyre. A long contact patch has more patch-length in which to displace water. The rear edge of a long, narrow contact patch has more contact patch ahead of it to dry the road, & so has more grip.

Wide tyres have the reverse situation: a short, wide contact patch, which displaces less water.

Taller, narrower tyres offer a range of advantages, but raise a question about grip in dry conditions. At least in part, this will be compensated for by an increase in the length of the contact patch in the larger diameter tyre.

Vessyl – the cup that knows what you are drinking – update



Vessyl has sensors that can detect what you’ve poured into it, & how much. Through the day, it can track such things as water, caffeine, alcohol, sugar, & protein in what you’ve drunk, plus your hydration level.

http://www.theverge.com/2014/6/12/5801106/vessyl-smart-cup-that-knows-exactly-what-youre-drinking

TechHive has a highly critical article. Check the comments – turns it into an interesting discussion.
http://www.techhive.com/article/2457644/why-have-consumers-spent-1-million-on-vessyl-an-absurd-calorie-counting-cup.html

Are the TechHive criticisms justified? Obviously, there are limits to what the device can measure. Limitations include:
• anyone who expects Vessyl to count all of their consumed calories is going to be disappointed
• users it will have to be prepared to change their habits – e.g. always carry the device & use it for all liquids consumed
• hydration: obviously, the user's water intake can be measured. Water loss, the other half of the hydration equation, is quite complicated. Caffeine & alcohol intake have a bearing, & Vessyl measures those, but water loss due to perspiration depends on the temperature of the day & exercise. Some fairly vague claims are made about, "your unique hydration needs", in the faq at https://www.myvessyl.com/faq, under the heading "How does my Vessyl help me stay hydrated?"

Vessyl is the only practical means I know, of measuring caffeine consumption. Caffeine content of coffee is not a standard unit. Variables include:
• type of coffee bean
• instant generally contains less caffeine than fresh
• grinding
• how the coffee was made e.g. filter verses percolated
• where the cup of coffee was made. A few years ago, a university study measured the caffeine content of over 90 97 short blacks from restaurants in Melbourne on the Gold Coast, Queensland, Australia. The strongest sample contained nearly nine times as much caffeine as the weakest*.

Its a well-known principle that, "If you can't measure it, you can't manage it." Google found over 46,000 matches to the preceding statement. Anyone who has an activity tracker has seen the value of this principle**. Vessyl is another measuring tool to help manage health & fitness.

Vessyl is available at the pre-order price of $99 for a few more days.
