They've studied how much force it takes to tighten a very simple overhand knot with various numbers of turns and developed mathematical theory that is good at predictions. Whilst it's interesting, most knot use is probably more interested in the opposite case of how much force is necessary to untie a knot, or how much force a knotted rope can withstand, or which knot configurations are comparable in strength. That'll take a much bigger leap in research but this is a good start.

The machines I use most are running Linux Mint or Android, but I've updated two Windows 7 desktops to Windows 10 and I like it. The Start menu is especially nice.

Criminals need light to see too. Try painting graffiti on a wall while it's completely dark. And I'll far more easily spot a torch flashing in my garden than someone hiding behind bush. I'll be lobbying my local council to do this.

Can I run AdBlock on it?

They say they'll operate like Google and Facebook, but they'll do the same as they've done with taxi regulations; ignore the rules. Don't be suprised if we hear about data protection regulations being flouted because Uber are "just a car sharing company, and not a marketting giant".

Yes, they didn't bail out the banks, but in doing so they allowed someone in Iceland to steal £30,000 of my money.

Which one was the Sabre Wulf theme based on?

And done the /8 now and another common ones are

commonName=UBNT/organizationName=Ubiquiti Networks Inc.

commonName=TS Series NAS/organizationName=QNAP Systems Inc.

commonName=Vigor Router/organizationName=DrayTek Corp.

commonName=homenet.telecomitalia.it/organizationName=TELECOM ITALIA SPA

commonName=localdomain/organizationName=Axentraserver Default Certificate 863B4AB

In fact, there are duplicate hashes appearing all over the place so it's an endemic problem.

Just scanned the /16 next to my home broadband and found a number of repeated certificate hashes and all belonging to systems identifying themselves as

*.myfoscam.org/organizationName=ShenZhen Foscam Intelligent Technology Co,Ltd

Seems to be a network enabled camera.

I get it now. They're going to kill the candidates before they launch them. No need for food, water, air or a safe landing.
