European datacenter energy consumption set to triple by end of decade

Data Centres don't actually consume any energy...

they just transform it from a high-grade form (electricity) to low grade heat. The trick is to site the DC somewhere where the heat output can be used to replace other forms of heat generation.

$ky have recently extended their contract with Astra until the end of 2029, which is realistically EOL for the constellation at 28E.

Freesat is basically just an EPG; the channel data is exactly the same as Sky receivers use.

Telcos scolded for unwanted erection of utility poles in race to wire up Britain

Re: Like any other superhighway

Party Line - the two phone wires ('A leg' and 'B leg' I think was the terminology) were connected to two houses. In one the bell and dial were wired between A leg and ground, in the other they were between B leg and ground. Hence dialling and ringing could be handled separately but the speech circuit was common.

UK's 'electricity superhighway' gets green light just in time for AI to gobble it all up

Re: Hmm

Also it's less easy for a Russian trawler to 'accidentally' cut a cable if it's 20 miles inland and 100 feet up in the air.

A long buried or submerged cable has a significant capacitance to ground, which in an AC system has to be charged and discharged 100 times a second. That current creates extra I^2R losses.

Rite Aid admits 2.2 million people’s data stolen by criminals

Has Windows 11 really lost marketshare to Windows 10?

Re: Faulty statistics?

Win-11 is no longer identifiable by the User Agent string on http(s) GETs, it always returns "Windows 10.0" (maybe M$ were afraid that takeup might be a bit slow and didn't want to provide ammunition for their detractors). There is an alternative "Client Hints" API available but Firefox refuse to have anything to do with that. I assume that StatCounter have found another way to collect the OS version information.

Ten years ago Microsoft bought Nokia's phone unit – then killed it as a tax write-off

Re: Myth of charging Nokias once a week

You could also use the alarm function without the phone needing to be switched on. I still use a Nokia mobile as a travel alarm clock; it needs charging maybe once a year.

Watchdog calls for more plugs, less monopoly in EV charging network

Re: It is still not as simple as pulling up in a forecourt and filling up a tank

The idea is to allow those who cannot charge at home to pay the same price for electricity as those who can. As noted they would also have to pay for the parking space separately.

Re: It is still not as simple as pulling up in a forecourt and filling up a tank

Why can't chargers work like ATMs?

I don't need an account with every bank to get cash from their ATM. The money is taken from my home account.

The electricity companies could issue an electricity debit card; energy I extract from a roadside charger is added to my home electricity bill at the same cost as if I had plugger the car in at home.

Obviously the charger supplier will have to be paid, this could be done on a time basis in the same way as car parking.

Kernel kerfuffle kiboshes Debian 12.3 release

Not just Debian

I run Arch Linux on Raspberry Pi, currently kernel 6.1.64. Last weekend I discovered the root filesystem (on a USB SSD) was read-only due to a corrupt journal. Thinking that the SSD was faulty I copied the contents to other media and got it working again. It now seems that this kernel bug is likely to blame.

The latest kernel for the Pi on Archlinux ARM is 6.1.66. So do I install that or wait for 6.1.67? I think I'll wait.

How to deorbit the Chromebook... and repurpose it for innovators

It wasn't hard once

I've just retired my Acer C720 Chromebook, which has been my backpack companion for just short of 10 years. Back then it was possible to flash a custom BIOS (SeaBIOS?) and then install a standard Linux distro. I gather it's not so simple now.

The only thing wrong with it is a lack of memory - 2GB (soldered-in) is very limiting nowadays.

Re: Windows 11 use has jumped from almost 9 percent in March (2022) to 23 percent in April.

Something that doesn't seem to have been widely publicised is that it is not possible for a website to distinguish between Windows 10 and 11 using the User Agent string. Naturally there is an alternative which is vastly more complex and only available for the Chrome family of browsers, but it means that measurements of Win11 uptake need even more than the usual pinch of salt.

Re: South don't work in the North

In the early 70s I had a summer job at a major manufacturer of colour TVs. At the time all TVs used the RCA shadow mask tube which had three electron guns in an equilateral triangle (the Trinitron was invented later to get round the RCA patents). Sets for the UK were built Blue Gun Up, those for the antipodes were Blue Gun Down (ie the CRT was installed the other way up).

Re: Solution in search of a problem

How about the system used in New Zealand for taxing diesel vehicles.

NZ has a lot of non-road use for diesel fuel (eg farm vehicles and off-grid generation) so there isn't a fuel tax on it. Instead, diesel vehicle owners have to buy mileage vouchers which are tied to the vehicle's odometer reading, and it is illegal to use a vehicle on the road if its mileage exceeds the voucher figure. The odometer is checked for calibration and tampering as part of their MoT equivalent.

Re: The big problem

Having UPS power for your DECT base station, router and fibre termination is all very well, but what about the green cabinet at the end of the road, whatever THAT connects to and so on? What power provision has been made, how long is it supposed to last and when was it last tested?

UK government in talks with datacenter operators over blackouts

Problem?

A 1MW data centre powered by a diesel generator will use about 300 litres/hour (assuming efficiency as a perhaps optimistic 33%), so 900 litres for a 3-hour outage. A fuel tanker holds around 25000 litres, so one round per day will keep 30 such DCs online.

Re: I am very dubious about this!

Isn't the round-trip-time to the satellite also an issue? Certainly with 2G the transmissions from the mobiles are time-division-multiplexed and so have to be carefully timed so that they arrive at the base station in their correct time slots, IIRC this limits the range to about 50 miles.

Vital UK customs system outage contributes to travel chaos at its borders

"According to The Guardian, GVMS has suffered a systems outage since it was temporarily taken offline during an update to another HMRC customs system, handling import and export freight, known as Chief."

So sometime. maybe months ago, someone made a change to a configuration file or startup script which caused the system to fail the next time it was rebooted? And I don't suppose such a teeny-weeny tweak ever got documented?
