The Register missed the point, which is that battery replacements will only be for failing batteries which would otherwise have necessitated an upgrade.

Re: None issue
" It was a selling point AMD pushed for cloud and off-prem platforms."
Meh. Cloud customers often don't know what iron they are running on, or even then if security protections are enabled. You have to assume cloud is insecure, because encryption (other then 1 time pads) only ever slows down an attacker.
Windows 10 Springwatch: See the majestic Microsoft in its natural habitat, fixing stuff the last patch broke
Re: Oh well
No, you will not get a 50V pots line with fibre, instead at the premises you get an Optical Network Termination unit with a Battery Backup Unit which contains rechargeable cells. These will locally generate the 50V required to operate legacy POTS termination equipment. Openreach will roll this out to every line, completely removing all the copper network.
The exchange will only need a router with all optical interfaces.
Re: Now lets get technical.
All very good, but not the nub.
The problem is that speculative executions can load from forbidden memory locations, and only cause a violation exception if their results are committed. Loading - processing - throwing the data leaks the contents through clever timing analysis.
Fixing it is hard. Lessons need to be learnt from the cipher/encryption community, that complete separation between userland and kernel is required for true security.
Out-Law goading for big compensation claims
Scots law differs from English law in that prior rulings are for guidance rather than precedence. A Scots court would take a dim view of attempts to claim excessive amounts of money for distress, and would see it as an attempt to use the court as a tool of war rather than a way to settle a dispute.
You're watching 4k TV on your main set in the living room. The kids don't want to watch what you are watching so go watch 4k TV in their bedrooms, separately from each other. Then your partner watches more 4k TV in the kitchen while making the dinner... Apparently there is simply no need or use for 1Gbps.
Intrinsic Safety (ATEX, IECEX)
MOVs and Zeners will protect against static discharge, but for real reliability (e.g. Intrinsic Safety) they then need to be protected against sustained overload with fuses, creepage and clearance distances, infallible connections, optocoupler "Distance Through Insulation"... It gets expensive.
Also, I've seen computer interface chips on motherboards explode when they are pushed into latch-up by inappropriately high currents (>15mA) through their inbuilt protection diodes.
Re: Most Behind the Times
"Since when did a microcontroller have cache, TLBs, an MMU, and all the other gubbins needed by an application CPU."
Microcontrollers have had these features, and more (e.g. graphics accelerators), for many years. It is a microcontroller if it has built-in peripherals to control things.
Re: Flexibility Doesn't Give Strength
Reminds me of the time I was interviewing a structural engineer for my self build, and trying to impress me with his knowledge, he said that my 1860 stone staircase was 'cantilevered' and the iron and wood balustrade takes most of the load. Suffice to say he didn't get hired.
"The flexing and bending of a wing in flight is intended by design, and a very rigid wing would break much more easily. Skyscrapers are also designed this way, to actually sway a little – it makes them far more robust."
They could make the wing more rigid, but it would weigh more, reducing payload, range, and efficiency. They don't actually care how much it bends as long as it doesn't break.
For civil engineers, it is cost vs bending, though the deflection limits are normally set by Building Standards/Codes.
Re: More than reported here?
A fall while wearing a Harness & Lanyard can cause suspension trauma, which can be fatal if not rescued quickly enough. Do not use a harness while working alone.
It has been Openreach policy for a while that their employees are not allowed to enter attics, maybe this incident was the cause? When they recently fixed my parents phone line, they left the cable dangling through an open window and left instructions for me to put it through the attic and connect it to the socket when I got back from work. It seems that these days if you want decent rural broadband you can upgrade the Openreach cable yourself ;)
I read 'magnetic isolation' as in a https://en.wikipedia.org/wiki/Circulator which was used in first generation mobile phones to help prevent the transmit signal jamming the receiver. 2G phones and WIFI use Time Domain Multiple Access so don't transmit and receive at the same time.
The article isn't very clear about the mechanism, but is it changing the antenna shape by heating?
