>On Windows - unlike Unix - your identity is separated from your privileges.
Modern UNIX systems have RBAC implementations that allow granular access to files and resourced and role shifting without changing identity,
Unfortunately they are rarely used for anything outside of the UNIX vendor provided tools (and not much even there) , as there is far too much historical cruft that doesn't know about this stuff.
You *might* have to replace your HDD after 4 years, but you *will* have to replace your SSD when the write endurance is up, and SSD warranties are being given in "data written", vs "years" for a traditional HDD.
What's your source for 15k enterprise drive failure rates?
Fundamentally, the article is artificially reducing the price of the Violin SSD storage by factoring in dedupe and compression, then comparing it to (unnamed, undetailed) 15k disk. Given that nothing much is detailed by the article in terms of comparative setups (EMC array with 15k disk vs Violin array with SSD for instance?) it isn't exactly heavy on facts and just seems to be a puff piece on Violin.
How does the fact that scarcity tends to drive up prices, that "nobody" would buy 15k disks anymore, and that flash can only supply 12% of storage demand fit into your world view?
>Flash isn't more expensive than 15K hard drives.
I'm quoting the article:
"We should note that Violin's raw $/GB cost is higher than 15K disk, but after deduplication and compression are applied, the effective $/GB cost is similar to 15K disk, even below it, depending upon the data reduction ratio. Intuitively, these customers are storing any immediate-access data, like mail, on flash too."
Also, a comparison of the cost of a random 15k drive vs a random "non-enterprise" flash drive means nothing, you have to look at a bunch of factors , MTBF, write endurance, power usage, warranty etc.
For instance, the Samsung 850 Pro 1TB drive, which is about £350 "has enhanced endurance, built to handle a 40GB workload daily". Which is fine if you only intend to write 40GB daily to it, what if you want to write 400GB? Then you'll need an actual enterprise SSD, which are many times more expensive..
Regular hard drives don't have a write endurance, just MTBF , so that isn't a factor for them.
to compare the price/gb of compressed and deduped flash, vs the price of raw 15k disk and say its the same.
esp. at the figures marketing tend to pull out of their asses with regards to the compressibility and deduplicability (might be a word) of data. You can compress and dedupe on any medium, so lets just say that flash is still significantly more expensive, eh?
There is no Euripides version...

How about cheap, shit, badly configured zigbee devices installed by the previous home owner that have never had a firmware update in their lifetime, and never will, regardless of the severity of any discovered security flaw?
Because that is the kind of crap people will have to deal with if this stuff takes off..
If you could in fact make a chip operate at "toasting element" temperatures, then you could toast with the waste computational heat.. for the 5mins every day you run your toaster.
On the other hand, hot and fast running chips replacing the heating elements in your water heater might just be a thing! Seems sensible to use that entropy to do something useful* instead of going straight to the waste heat, right?
*usefulness will vary depending on the vapidity of the work the processor is put to.
"1) Why does the boot not lock? Are you telling me someone designed a car where the only way to lock it is via radio? Stop buying these cars."
Normally you can lock the boot from the drivers lock in these cases. However, it requires some obscure left/right key turning to enable it, which no-one will be able to remember without looking at the manual for the car. Probably they disabled key locking of the boot at some point with one of those combos accidentally.

"may contain..." is a voluntary label with no required wording or separation of ingredient types.
However, it's use on a packet of peanuts is almost certainly to indicate that the packet may well contain traces of other "nuts", as the label is *not* required.
A label saying "Contains: Peanuts" and "Ingredients: Peanuts, salt" is required however....
Peanuts are a legume, not a nut, but are likely processed in the same factories that process actual nuts, so therefore putting a label on them saying "May contains nuts" is just the same as putting a label on cornflakes made in the same factory as crunchy nut cornflakes, for instance.
They may contain nuts from other processing lines that might have blown over or whatever, but they aren't nuts themselves.
"2. Most houses are draughty. Air leak is sometimes the biggest enemy of residential energy efficiency and cost reduction, exceeding even insulation in importance. Infiltration of undesired outside hot or cold air means exfiltration of desired heated/cooled inside air, which you then have to replace, at your expense. Many sources of air leak are obvious, like the aforementioned windows and doors, also unplugged chimneys, gaps between sills and foundations, and the like. Others are downright arcane, weird, who'd-a-thunk-it sorts of things. First you address the obvious ones, then you formally test, most often by employing a professional, but you could do it yourself."
Go ahead, make your house airtight and then get back to me if you survive the monoxide poisoning!
why is it so hard to opt out of data collection?
cf. Supercookies, ignoring "Do not track" settings, opposition to Ad and script blockers.
Multiple tick boxes needed to opt out of (or maybe opt into? who can tell) data collection with triple negatives and auto-re/un-ticking on page refresh.
Companies used to rely on freely given information from "representative" samples, via surveys etc.
Now they just want all the data , even from those that wouldn't have completed the survey because they don't see why they should give their life story to the company they just bought a fridge from.
And they go to great lengths to get that information, in many cases against the laws of the countries they operate in (e.g opt in vs opt out).
When a camera equipped police office goes off shift, it will be their job to declare to the desk sergeant if there is anything of evidentiary interest on the camera. If they don't, the camera storage will be overwritten tout suite.
Any complaints against a specific officer will somehow get delayed just long enough that the camera will have already been reused, unless the person making the complaint has a lawyer with a court order on hot dial.
There will be some "guidelines" that will indicate that after certain categories of police work, all the camera evidence is kept (like protest suppression policing) , but it turns out that in this case the procedures weren't followed correctly. Sorry, could happen again.
Problem solved.
Modern day CPU's are so fast that the 1/2 light speed (+) that electrical signals travel is pretty slow over any significant distance, which is why
a) on-die and incorporated caches are getting larger and larger and contribute such significant performance increases
b) Why three dimensional chip design and die stacking is a major focus of interest
1 Gigahertz means 1 cpu cycle happens while light travels 30 cm.
Chips run at up over 5 Ghz, so 6cm.
If it turns out the data you needed was on a RAM chip 2 meters away, 66 cpu cycles (at least) will pass while you are waiting for it to turn up, regardless of what bus, technology or whatever you are using for an interconnect.
"The Chocolate Factory state that "While neither we nor CNNIC believe any further unauthorized digital certificates have been issued, nor do we believe the misissued certificates were used outside the limited scope of MCS Holdings’ test network. CNNIC will be working to prevent any future incidents.""
So, How did Google "become aware" of these certificates?
Presumably Chrome reported back to the big Googleplex from inside MCS and ratted them out?
Nice bit of spyware you got there Google.
Don't forget, You'll be able to pay for special tariffs. Such as the "No Brownouts for me" tariff, better have lots of cash though.
Yeah, when I heard that the alternative to investing in power generation infrastructure was "Smart Meters" I figured that was the idea as well, rolling brownouts. The increased spying and police anti-protest measures are being put in place to crack down on the power riots...
My local MP's energy policy is apparently loft insulation, solar panels and hope, which pretty much sums it up for all the parties tbh.
I mean, I thought you saved money by centralizing everything for ease of maintenance and control. Now it turns out you save money by distributing and avoiding infrastructure while benefiting from "commoditization".
It almost seems like whatever you are doing currently is wrong, and you should switch to the opposite while spending cash on some vendors new kit.
Marketing eh.
And turned the service to shit, so I moved elsewhere.
Their secret throttling "beta" that went on for several months, affected all live users and wasn't announced or even mentioned until people complained was one of the motivators.
Oh, and the fact they actually promised not to do that when they took over.
I wasn't even on an "unlimited" contract , it had caps, precisely to avoid throttling.
What a bunch of lying cocks.
