Gunfire at electrical grid kills power for 45,000 in North Carolina

45,000 killed ??

Re: Good.

Another former Atari 800XL owner here:

Loved the machine, had a pair of 5.25" floppy drives (one needed 5 minutes to warm up before working!) and a 256kB ram expansion pack, hooked a brother thermal printer up and had lots of fun.

Sold the lot for a good price just before the market in them crashed to get my first PC (IBM model 30).

most of that stuff is outsourced to service providers theses days, I think it is a lot harder to get into the interesting IT that it was in the early days.

Re: How many homes was that, again?

>> Looking at my usage over the past year, I average just over 12 kwh

13.1 kWh here (and falling) over the last year, so 550w an hour. That actually sounds a lot but factor in the peak loads from the electric oven, induction hob, washer etc is kind of looks respectable.

And yes it is falling as more efficient kit gets installed as the old fails - yes "fails" as you have to take into account the manufacturing cost of anything your replace.

Re: Cold reserve NPPs?

>> Hydro is pretty fast to react

I remember during the tour of the wales "Electric Mountain" that the standby turbines are motored via the generators keeping the spinning and synced to the grid but with air in the water turbine bit, if they needed to generate they let the water in and were running full pelt is something like sub 5 seconds

Re: Rough timing

Plus I thought we (at least initially) were mostly clearing down the older surplus stuff and only recently sending the more recent high tech stuff.

Same for Russia of course, I did read (quite some time ago, might even have been a fictional WW3 scenario book) that one issue of a European wide modern war is that the availability of weapons would be a major limiting factor to the duration of the conflict, they quite simply could not be manufactured quickly enough.

Re: Local generation

"The reasons for central generation still apply,"

Electricity used to be small local generation which resulted in different voltages etc in different areas, one thing that the central generation gace us was a standard voltage and frequency and the ability to share the load across the country.

The central solution also has to keep the system stable, and for that you need lots big base load turbines - wind/solar cannot do that alone.

Aquaplaning in wet conditions as I found out myself - thankfully all ended up safe in this case

David Hicklin Bronze badge

>> The low-hanging fruit would be keeping a proper safety distance

That! An anti-tailgating system that cannot be overridden

I see all the time where the "overtaking" lane is full of bumper to bumper cars that all have to desperately slam the brakes on when the line slows down, with the cars further back having less and less time to stop as the reaction time gets eroded each time.

Usually the left lane (UK here) is empty for quite a distance, so I usually pull over into it whilst they sort themselves out and the line of cars eventually sort themselves out.

FAA wants pilots to be less dependent on computer autopilots

David Hicklin Bronze badge

And the few cases that might exist are usually down to bad cockpit management (often for cultural reasons) and/or bad training.

Obviously the ones where they did follow the training and procedures where one pilot takes over the controls whilst the other fault finds/diagnoses rarely get to feature on Air Crash Investigation, but where they do the contrast is quite striking.

Waiting for speedy broadband? UK's Openreach prioritizing existing work over fiber expansion

Re: They had a nifty machine ..

In most towns and cities in the UK the ground under most roads is a rats nest of criss-crossing pipes, cables and conduits. You just need a quick peek the next time they are digging up the road to fix a water leak/power cable short to see the mess down there.

Run something like that here and you will either rip up gas/water/electric - of they next time they fix one of them they will rip up the fibre.

Re: There are so many of these incidents

I have been part of one such migration back in the 1990's which other than a few relatively minor teething issues (you will always get some) went quite smoothly on go live day.

The two take outs I remember most from this were weeks of testing/training sessions with the supplier involving *all* departments of the business, and that as far as possible we adapted the business processes to fit the new ERP system rather than the other way around.

Re: If

That seems to be the general answer to all these ERP/Finance systems by any of the major players once the salespeople have sold the snake oil.

Aviation regulators push for more automation so flights can be run by a single pilot

David Hicklin Bronze badge

>> You could argue well if they can do automatic landings then it's not a problem

You will then also hit the other extreme that already exists with the current automation: the pilots do not spend enough time actually flying the plane to stay proficient

David Hicklin Bronze badge

>> If you work in a shop or an office it is required by law

It may not be the law but in general it is undesirable and should be avoided if possible (assuming your employer cares about you of course).

I have been in situations like this, usually late at night trying to fix some broken IT kit but my manager did phone me every 30 minutes or so to check I was still OK (and was it fixed yet!)

David Hicklin Bronze badge

>. Air France Airbus that went down in the Atlantic.

I think they also made reference to the sudden event of going from a smooth flight (OK thunderstorms were nearby) to the next instant the alarms going off and throwing control back to the pilots and expecting them to "just take over" without being fully situational aware. They then became focussed on one thing with one pilot pulling up whilst the other pushed down until it was to late.

All they really had to do was to fly straight and level.

Self driving cars have the same problem where the driver is expected to take over in an instant if the computer craps out.

Re: Damn

That's the fault of the market not the cost of producing the stuff , in the UK the most expensive source sets the electric "market rates" - it used to be renewables but now it is gas. hence windfall taxation of the energy producers

>> fractional reserve banking, ie allowing loans to be made (and debt to be created) without having the corresponding deposits to back up that loan

Now I could be *very* wrong here but is that not what we had in the 1970's / early 1980's ? Loans and mortgages were bloody hard to come by in those days until they relaxed the financial market rules , and triggered the explosive economic boom (and busts) that followed.

Besides, they have to borrow the money to lend it out first, and if they relied on deposits to back it all up then there would be very little lending going on

Re: Hang on a minute

That took while to parse as well

I think they are trying to say (rather badly) that the price today is 155% higher then it was 5 years ago, but the peak was a year ago and since then it has declined 73% to reach today's price (5 years + 155%).

The ones who have lost are those that jumped on during the surge to the big peak a year ago, causing the price to surge even more (assuming they hung onto them hoping for an ever higher price), whilst those who have held BC for >5 years were cashing in to make a killing.

Tesla recalls 40k cars over patch that broke power steering

David Hicklin Bronze badge

Re: Power steering

> Steering that was never powered in the first place is

When I first started driving in the 1980's power steering was very much a luxury, cars were much lighter and had relatively massive steering wheels requiring a large number of turns.

Then they got heavier (more protection) and for looks the wheel got smaller. I remember when we got our first car with PS that the wife finally realised what had been giving her shoulder strain!

But today if it fails you know about it and if you are on a roundabout you could easily run off the road or hit another vehicle.

Compaq support engineers

In a past life at another company we had them in to replace the Pentium CPU's that had the floating point bug (remember them?).

Guy came in using a screwdriver to lift the old CPU out which went well until it slipped and ploughed into the motherboard, those ultra fine chip legs (even in them days) don't appreciate a visit by a screwdriver.

Management was not pleased to say the least and a new motherboard was provided post-haste.

And the poor service guy? No idea what happened to him but it was not looking very good when he was spending most of his time on his phone trying to avoid being evicted from wherever he was living, maybe a bit more attention to the job in hand might have helped.
