AI software that can reproduce like a living thing? Yup, boffins have only gone and done it

Peter Cochrane

A Redescovery From Over 25 Years Ago

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!

4G found on Moon

Peter Cochrane

A pity we have a lot of trouble getting 3G in Suffolk. Thinking of moving to the moon!

Russia could chop vital undersea web cables, warns Brit military chief

Peter Cochrane

This recent realisation is way out of context and nothing we haven't known since before WWII. Cables are cut every day by trawlers and the biggest ships dragging anchors to afford extra stabilsation in stormy weather. Much ado about nothing! Peter

Home Sec Amber Rudd: Yeah, I don't understand encryption. So what?

Peter Cochrane

Fashionanle Ignorance

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 might be a hipster honeypot but it's rarely worth the extra hassle

Peter Cochrane

Old Thinking Never Fits a New World

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!

UK not as keen on mobile wallets as mainland Europe and US

Peter Cochrane

Unreliable Mobile Nets in the UK

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!

Networks in 2016: A full fibre diet for UK.gov

Peter Cochrane

Such a Pity The RoW Has Got IT All Wrong

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....

Ofcom should push for fibre – Ex BT CTO

Peter Cochrane

Re: Cui Bono?

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!

Peter Cochrane

Re: Copper

WRONG ON ALL POINTS!

Watch the videos, read the papers, look at the presenations

Dr Syntax - CLOUD!!

Image you were dumb enough to operate with a HA 20% of what you intended to store! Why an earth would you buy insufficient cloud storage capacity?? AND remember, cloud computing also means running apps on line. BUT there is much much more at stake!

Peter Cochrane

Re: Why not wireless?

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.

Google's so smart it's discovered SHARKS HAVE TEETH

Peter Cochrane

SHARK BITES ON SUBMARINE CABLES

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!

GCHQ to share threat intel – and declassify SECRET inventions

Peter Cochrane

When the need to share trumps the need to know, new things happen!

Elderly Bletchley Park volunteer sacked for showing Colossus exhibit to visitors

Peter Cochrane

The Bletchley Children

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....
