...on our seismometer. It caused a strong event, but with an very undefined epicentre. I guess that many Galaxy 7 owner could no more read the notification message on the screen.
Unfortunately this aggressive behaviour is typical among companies selling ham-radio related hardware or software. I got into ham radio in 1980, and after a few years the so called "ham-spirit" evaporated and was replaced by money greedines. I am no more into this, and I do not regret the decision I took. Communities that grew around projects like Arduino or Raspberry PI are more open and technologically-challenging than ham radio today. I wonder why a young student should take his ham radio ticket, and get involved with this stuff, when there are so much interesting things in the SBC wolrd, that furthermore require no license at all!
...to try to deliver internet connectivity everywhere someday, could we please have back BBC World Service on shortwaves also in countries that are supposed to be connected, but actually aren't ? I travel extensively all along Europe, and having a *working* mobile internet connection fast enough for web radio listening is still a nightmare, and usually it costs you an arm and a leg, especially if you surpass your monthly data cap. I had shortwave radio on my car, and I could receive BBC without problems during my travels, but they turned it off, since "there is internet, who cares of shortwaves"....sigh!
There are some problems to solve before. Frankly speaking, while people are busy connecting developing countries to internet, I meet more and more people who are dissatisfied of internet, and have plans to spend less and less for internet access. Maybe it is better to focus on the quality of what it is delivered, rather than how to deliver it.
...with a Samsung Galaxy Notes 7! This smartphone has been carefully designed with privacy in mind: it incorporates a very low level phone formatting mode to erase completely not only data, but also chemical substances that could compromise user's privacy.
...the smartphone CPU executes a Halt and Catch Fire instruction. Apps available in the google market should be better screened for this serious threat.
When quoting Arnold I have been a little incorrect, since five figures of precision in the measurement of physical variables actually give you a two months forecast. But I studied this about thirty years ago...
If you want to estimate the error, if n is the number of months of the forecast and eps is the measurement precision, the error is given by:
10^(2.5n) times epsilon. As you can see the error rapidly increases, although the formula I transcribed from Arnold's textbook is quite rough (toroidal Earth, steady flux and negligible viscosity). Not a bad approximation for estimating trade winds flux, however.
People at MET probably took care of the propagation of numerical errors in the calculation, by increasing the grid density and maybe setting up a system capable of working with quadruple precision. However the problem again is the needed precision of input data, that increases exponentially with the time forecasted.
Arnold in one of his textbooxs demonstrated that, to make a weather prediction one month in advance, you need to measure pressure, temperature, wind speed and humidity with at least five significative decimals. He used sound mathematical methods based upon a theorem by Poincaré. With all the respect for technical skills and competence of people at Met Office, I trust more what Arnold demonstrated using nothing but paper and pencil. Good math is never overcome by brute force computation.

But I expected you to come up with something more original...

Samsung Galaxy 7 line of products will soon rebalance the percentage.
Their real goal is to shadow out sunlight with the satellites, in order to mitigate global warming...
The list of their requests has been strongly encrypted with their own software, but they forgot to send the key to Trump....
...for viewing the towering inferno: it is a Samsung product, after all.

When smartphone temperature exceeds 60 degrees, the app activates the GPS and sends the coordinates to the fire brigade.
In case you haven't noticed, you got both things delivered to you. Be happy!
...your preferred Samsung Galaxy Note 7 joke.
This issue of the Washington Post will be great for firing up the grill this Sunday!
...the smartphone CPU executes a Halt and Catch Fire instruction. Apps available in the google market should be better screened for this serious threat.
...the burn test ?
...is busy transforming your high performance battery (and smartphone) into junkyard scrap!

Elop never worked for Facebook.
On the positive side, thanks to gravity the exit cost from space is nil.
Wasn't it because they used smartphones of galactic origin ?
you, insensitive clod!
