Well, except that it isn't a mere month. Unpowered data retention is around 10 years for relatively unworn flash and around 1 year for worn flash. Powered data retention is almost indefinite (doesn't matter if the data is static or not). The modern SSD controller will rewrite blocks as the bits leave the sweet zone.

The main benefit, though, is that SSD wear is essentially based on how much data you've written, which is a very controllable parameter and means, among other things, that even a SSD which has been sitting on a shelf for a long time and lost its data can still be used for fresh data (TRIM wipe + newfs). I have tons of SSDs sitting on a shelf ready to be reused when I need them next. I can't really do that with HDDs and still expect them to be reliable.

Hard drives have a relatively fixed life whether powered or not. If you have a modestly used hard drive and take it out and put it on a shelf for a year, chances are it either won't be able to spin up after that year or it will die relatively quickly (within a few weeks, possibly even faster) once you have spun it up. So get your data off it fast if you can.

So SSDs already win in the data retention and reliability-on-reuse department.

Simple. There probably weren't many who knew both
1) The floor needed reinforcing and
2) It hadn't been done.

Occam's Razor says communications error.

Everyone actually in charge of building the thing would have believed the floor would be adequate. Whoever was in charge overall dropped the ball (maybe misread a statement to the effect "floor shall be reinforced to such-and-such-a-spec" as "floor has been reinforced to such-and-such-a-spec".

I heard GW Bush claim Saddam had WMDs too, and that didn't happen did it?

Actually, that one did. It resulted in both "Gulf War Syndrome", and a pretty big scandal where Monsanto brokered the deal to sell the machines to manufacture chemical weapons to them from a German company, said deal routed through France. But nice try.

PS: Plus we sold them the Sarin the used against their Kurdish separatists directly, so we knew they had it at one time, and were just hoping they hadn't used it all up so we could say "Aha! Stockpiles!".

Maybe robots could build desalination plants?
It's pretty damn sure that humans never will ...

We're well on our way to getting one built in Carlsbad, near San Diego. I hope there are more to follow.

"It will produce 50 million gallons of water per day and will provide 7% of the potable water needs for the San Diego region."

Cool. Now you only need to build another 14 of them to satisfy the water needs of the area...

Comment This has all been done before (Score 1) 599

and it will all be done again. To no avail. At least since I was in 7th grade (that's about 30 years ago) there have been special sections, schools, what have you for getting girls into mathematics and technical subjects. Usually they flop big-time. Sometimes they appear to have some success for a year or two and then flop. The sensible person would look at these failures and think that whatever the cause for the difference, it cannot be solved with this sort of segregated schooling. The politically motivated educator just keeps doing the same thing over and over again.

Comment Re:How convenient for Apple... (Score 5, Insightful) 138

Ohh FFS -- that was at the initial launch and not done as a fuck you but simply because they were more interested in just getting the new product and OS out the door.

It was definitely a "fuck you, this is a phone; this is not another fucking Newton".

Full disclosure: I was an Apple Core OS kernel team member at the time. I wrote 7% of the kernel that runs on the things.

Comment Re:They were actually unhappy with Pearson. (Score 1) 325

No, it is made very clear that Pearson was a subcontractor to Apple. The total contract was Apples, so the fault/responsibility is Apples.
If they had simply sold the ipads and said 'go look for some software' it would be very different.. but they did not.

When someone preloads software that you request be preloaded on a device, that does *NOT* make the software vendor of that software a "subcontractor".

Unless, you know, (1) there was a contract between Apple and Pearson relating to contract line items, and (2) There was *no* contract between LA Unified and Pearson, and (3) LA Unified did not specify the curriculum software to use, and (4) Apple was acting as a slaes agent, rather than as an intermediary.

The breakdown they (LA Unified) gave was:

Special Case ($80);
3-year Apple Care warranty ($150);
Pre-loaded apps ($13-$21);
Pearson curriculum ($150-$300);
PD ($20); and
Buffer Pool ($20).

So it's pretty clear that they meet none of the criteria for subcontractor under the contract.
