Do SSD failures follow the bathtub curve? Ask Backblaze

Spazturtle Silver badge

Re: What I Wanna Know ...

Most SSD failures are due to the controller dying which you can't predict. As the actual NAND chips wear out you will see the reallocated sector count rise and eventually the drive will switch to read only mode.

That's actually an unsubstantiated hypothesis, and the more recent evidence indicates that magnetic fields actual cause the atmosphere to be lost faster.

Largest local government body in Europe goes under amid Oracle disaster

Re: Great job!

The government bailed out the banks by forcing them to issue new shares which it bought, so the shareholders did lose out as their shares were diluted by a large amount (since the share price had dropped so low the banks had to issue a large amount of new shares). This is why the government ended up owning a large amount of shares in several banks.

Re: Great job!

"The government could have taken over the banks and reformed them, but it didn't - it bailed them out"

Bailing out the banks IS taking over them, that is why the government is a major shareholder in several of them.

The world seems so loopy. But at least someone's written a memory-safe sudo in Rust

Re: Perhaps /etc/sudoers more of a problem than perhaps C memory safety

"It is possible to write safe C code as well. "

The issue is that it is not possible to guarantee that C code is safe, given how many times memory issues have been found in critical c code written by experience coders.

UK air traffic woes caused by 'invalid flight plan data'

Spazturtle Silver badge

Re: Resiliency – we've heard of it

They said that they would be able to fix it very quickly and if won't cause disruption if it happens again. So I suspect it might simply have been that nobody working there even knew they had to manually clear invalid flight plans and it took 4 hours to get in touch with the guy who retired 30 years ago.

"invest the £300 million into sorting their sewage overspill problems instead"

They are not allowed to do that, Ofwat only allows new sewage plants to be built when the existing ones are routinely going over their red line, but Ofwat tends to set the red line above the plants maximum capacity so the red line can never be reached.

In the UK being found guilty requires that both your body is guilty (so you did the thing you are accused of) and that your mind is guilty.

Apple's defense against apps vandalizing other apps still broken, developer claims

Spazturtle Silver badge

"Do apps on MacOS get installed in user space or something"

Apps are just uncompressed zips that to install you just drag and drop into your Apps folder.

From what I can tell Apple's security stops apps from directly changing other apps without user input, but it doesn't stop the file picker from selecting other apps files, so you can open TextEdit and open the settings file for another app, make changes and then save them.

Judge snuffs man's quest to have AI-created art protected by copyright

Spazturtle Silver badge

Re: Hollywood beware

"Add a little bit of "AI" to the mix and you have the risk that copyright in a movie or tv production could be challenged on the same basis: that humans didn't do the whole thing, only a part."

No as the studio would be claiming that the operator of the computer was the creator.

This case was about a guy trying to claim that the AI itself should be credited as the creator and should hold the copyright, the court told him that that wasn't how the law worked and that he was the creator and should register the copyright in his name.

Tesla knew Autopilot weakness killed a driver – and didn't fix it, engineers claim

Former DEC employees to rally against stagnant pensions post-HP

Spazturtle Silver badge

Re: Drivel

"The problem is that the pemsion fund's rules didn't include cost-of-living increases"

If it was a fund then the pension would increase in line with the performance of the fund's investments.

I can't find anything that shows that it is an invested fund, from what I can see it looks more like a defined benefit pension like the NHS pension where you give up part of your salary in return for the promise that they will find money from somewhere to pay you when you retire.

"cost-of-living increase"

Where is the money for this meant to come from?

Spazturtle Silver badge

From what I can see it doesn't look like the DEC pension was an invested fund that people paid into, so why would anyone expect the value to go up. If it isn't invested then how is it expected to grow in value?

Bank of Ireland outage sees customers queue for 'free' cash – or maybe any cash

Re: the edge of space by US standards

There is no internationally recognised line between the atmosphere and space.

The Kármán line is ~84km which Kármán calculated as the altitude at which in order to generate enough lift for level flight you would need to be traveling at orbital speeds, most space organisations round to it 80km, the FAI who are an aviation sports body are the ones who round to 100km.

Even if they got the designs to a US ship it would be useless to China, they don't have the metallurgy to build any ships to those designs. Look at their new carrier, the flight deck is already buckling.

First US nuclear power plant built this century goes online

Spazturtle Silver badge

Re: ROI?

The cost for both reactors is $28b.

They will make around $876m a year per reactor so $1.75b a year (gross profit) and electricity prices are only going to go up over the reactors life.

The plant has a total running cost of $0.023 per kwh, so each reactor will cost $225m a year, so $450m for both.

So that means the plant will have a net profit of $1.3b a year (at current prices)

So assuming electricity prices don't rise it will take 22 years to break even and then have another 40 years of profit, in reality they will break even much sooner.

Brit broadband subscribers caught between crappy connections and price hikes

Re: Genuine question

The UK has has a Net Fixed Capital Growth of 0% for 30 years, so whilst we are producing more wealth the cost of our imports has also gone up and they cancel each other out.

Having money help you make more money, and when the pie stays the same size this means that wealth begins to accumulate amongst the already wealthy.

For comparison Germany has been at 1% for the last 30 years.

Re: Jeff's BO putting the cart before the horse

"The generally accepted definition of space is 100km. "

The generally accepted definition is 80km, the only people who use 100km are the FAI who are an aviation sports organisation, an they are considering switching to 80km.

Karman calculated ~84km (52 miles) as the altitude at which in order to generate enough lift to sustain level flight you would have to be traveling at orbital speeds. Most countries round this to 80km and the US rounds to 50 miles.

That's only due to the specific impulse of kerosene, if you instead use hydrogen which has a much higher specific impulse then engines can remain efficient into hypersonic speeds.
