Re: Price-performance
@thames:
Check out QEMU or Unicorn. This is nowadays mainly how GMP is performance optimised on all those platforms.

It is still 150 times as expensive as tape if you keep your tapes for 15 years (both StorageTek (10K) and IBM (Jaguar) state that their tapes are good for 30 years).
(Tape drives and library not included, you may add a tenth to a fourth of the cost or so, depending.)
Why do you think that StorageTek can do it as a service for one tenth the price?
Tape may be dead - in the heads of those that do not do the math.
Not that I like saying it, but when comments like that appear:
Yes, iOS is more secure, at least than for example Android.
This is obvious ot any tech-literate. Only a tech-illiterate, or a heavily biased mind, would say something else.
Android allows install of any app without any signing, has a tricky capability system that most users can't understand, and that in most installations users can't do much about the apps capabilities. Apps can get to more data and other systems on Android, which is sometimes useful but opens up to more ways of compromising data and software (which is exactly why iOS don't allow those extra ways).
Most Android phones don't get important security updates to the OS, so users run with old unpatched versions.
Just compare the number of malware programs, the percentage of infected devices, and the ways that the devices are compromised, and it will be obvious, for "any tech-literate".
The only one that are fooled in this case is the article writer, who hasn't understood what this is and how it works, and the whiners in this thread who believed the article whiteout checking what it is actually about.
This isn't giving more control to apple, this is giving more control to the customer and less to the service providers.
The only devices that are locked are those that are sold subsidizes from the service providers. They are often locked to that service provider so that you can't take the money and use it with another service provider.
Device manufacturers almost always want to have their devices usable with as many networks as possible so that they can sell as many as possible.
You can often unlock the device when the contract with the initial service provider has expired, for example after two years.
This has been how it has worked since almost the beginning of the GSM era, at least 1994 or so.
No, it isn't. But it certainly is about less service provider control.
If you had any idea of what you were talking about, you would know that the soft SIM is only one option. You can perfectly well swap in any SIM you like.
This gives more control to the customer, less control to the service provider.
The article has got it exactly wrong.
You can put any SIM you want in it.
But it, currently in the US and the UK, ships with an Apple SIM, which lets you choose between the real networks and roam between them.
So it doesn't put any more power at the device manufacturer, it only makes the customer have more choice.
So all of you whiners here - can you pleases stop now?
If you had used the OS, you'd know that you can restrict most such permissions on an app-by-app basis. The user is asked with a dialog the first time the app tries to use such permissions, and can change the choice at any time. (I said most - still not all permissions are settable, for some stupid reason.) If it uses permissions that it doesn't need, it gets down rated or in some cases even rejected.
"While increasing speed, it also increases traffic by multiplexing communications, which would further hamper networks."
So MPTCP could increase traffic, and that is bad?
With that reasoning, we should stop using the networks at all, since using them means network traffic, and that is bad.
"Stateful systems aren't equipped to handle distributed state, thus pretty much any system that isn't an endpoint of a MCTCP connection is useless at doing anything besides simply forwarding the packets."
Forwarding is exactly what the non-endpoints should do, and nothing else. They do not need to be, and should not be, stateful in any way.
"What I will agree with you on the whims of corportations is regarding the research on "side channel attacks." I don't really understand why being able to infer throughput, congestion, packet delay, etc of other ISPs is an issue. None of that information sounds horribly proprietary, but what do I know."
I too agree with this, fully. There are much simpler ways of measuring the performance of a competitor's network - just send traffic through it.
That is some kind of 12 disk Blue Ray cartridges. No one knows how long they will actually hold the data.
Go for LTO instead. Even LTO-6 is half the price for both the drive and the tapes, and then you get 2,5 TB tapes (+ compression). If you want to save a bit on the drive you can go for LTO-4 or 5, you can later upgrade to a LTO-6 drive, or perhaps 7 when that comes out. LTO drives can normally read and write tapes one generation back, and read two generations.
LTO tapes are supposed to keep data for at least 30 years. I have seen bugs with the small RFID memory though that has made the drive think a tape is empty though it isn't. At least that should be solvable by masking or removing the RFID tag, but I haven't had the possibility to try that yet (the tape got rewritten before we discovered that). But always keep at least two copies of your valuable data, preferable more, and preferable in different locations of course. The Sony thing seems to have RFID memory two, so that is not necessarily a con for LTO, it could possibly be just as bad with the Sony thing.
Hopefully those HP SSDs won't lie about data persistence as most consumer crap SSD drives do.
Most of these gaming drives have no way to remember any writes in the write cache and will forget them if they happen to loose power while still haven't decided to flush the write cache. To make things worse, most of them just *ignore* and sync-to-persistent-media commands from the host (because that would hurt performance, and they would look bad in tests like this one). If you loose power while there are unflushed writes in the write cache, you could easily get corrupt data or in worst case loose your entire file system.
Real drives have supercapacitors or other techniques to actually remember what the host has told it to remember. The drives above are just toys, and should only be used as such.
