This was first used to crack the Travelling Salesman Problem in the early 90s and the routing of mobile traffic in 1995. Optimum solutions were found at 30 - 33 cycles of the reproduction process that employed infanticide, matricide, and insest....in the code of course. Amazed that it has emerged as a breakthrough yet again!
At what point in our society did it become acceptable to declare your own ignorance and be proud not to know something so fundamental.
It seems to be a British management disease, and perhaps the ultimate arrogance, to suppose you can manage things you do not understand. Her stance on encryption is a classic example - has she got hold of the worng end of the stick or what!
BYOD works really well in organisations that get rid of all their old security and operational practices such as 'in-house provision' and clock watching management. Almost every hi-tech company I work for is way ahead of the thinking and opinions expressed in this article. BYOD = freedom and greater productivity!
Why is this a big surprise - the UK has the worst mobile networks of any EU country! No signal. No 3G signal. No 4G almost everywhere. Far less than 90% coverage by each carrier. Weak signals and continuous drop outs. Mobile wallets do not work all the time - but plastic does!
FTTP cost in against copper under all circumstances in 1986 let alone in 5 years time - less of course you see glass as another variant of copper and continue with the same old practices. I do wish these folks would step out of their offices, go see what other countries and companies are doing. 24Mbit/s is a joke - just try it for Cloud Working - and especially when the upload speed is only 6Mbit/s. But don't worry, the good old UK will lead the world from the back by concentrating on yesterdays needs....
You sir at the bottom of the user/demand stack - as a country we cannot compete internationally on the basis of you limited narrow needs! People are trying to run businesses, get trained and educated, delever healthcare and much more and the need Gbit/s speeds. It aint rocket science!
Because wireless cannot provide the density of access require or the bandwidth needed - and it has a far more important role in the IoT and mobility. If it were that easy or remotely feasible we would have done it! It is not even remotely/theoretically possible! BTW - the world leaders are moving up to 10Gbit/s on FTTH and the current standard is 1Gbit/s. Tou might like to visit my home page and look at some of the presentations, videos and published papers.

I worked on the development of the first optical fibre cables from 1980s onwards and this problem first showed up on an ATT trial off Gran Canary (around 1983) when they had left off the Glover Barrier - i.e. the cable was no longer screened. The AC ripple on the 20kV DC power feed attracted one species of shark that hunts fish by detecting the electric fields generated as they swim or struggle if they are in distress.
So very easy to fix - replace the Glover Barrier and the ripple is screen - and then the sharks ignore the cable. AND BTW cables are only ever armoured is shallow water when they cannot be buried - and when they are subject to anchors, fishing trawls, and worse - tidal abrasion on rocks. In deep water the cables either lay on the sea bed or form catenaries spanning undersea mountains, ridges.
and canyons.
Sadly, we live in a world of growing data and rapidly rising ignorance!

I was helping to organise a visit of 70 American technologists to Bletchley Park, but if Colossus is not included what would be the point. They need to see more than old wooden huts and posters! Colossus is the key technology that everyone wants to see and photographs just don't cut it.
The children who are managing this site really do need to grow up! But then again they are probably so old that they are unable to change.
What a shame....
