"provide us the vendor independence"
You know those bank accounts that offer you a good interest rate then drop it after a year? At least you can move your money without too much trouble and have it in multiple banks for added peace of mind because electronic money all basically a 'commodity'.
How do you deal with a cloud provider, once established, changing the rules?
In a nutshell that is one of the biggest issues. Sure there are others like data sovereignty / jurisdiction and so on, but unless you can easily migrate your data and process from vendor to vendor you are simply putting your balls in a big vice and inviting them to turn the screws later...
Re: "extra load put on them"
If you have a RAID system you really, REALLY, should be doing a periodic "scrub" to verify all used sectors on all disks so when (not if!) you get a HDD failure there is a decent chance of the other HDD being clean enough to do a rebuild.
ZFS has a scrub command, and Linux software RAID with recent-ish kernels supports a check command to do a scrub(see http://en.gentoo-wiki.com/wiki/RAID/Software#Data_Scrubbing), while some hardware cards (like my Areca 1210) also support such a periodic background check.
Double parity is also a good idea, though matters more if you have several disks (say 5+), but is still not a substitute for a backup held elsewhere.
"I'm sure the guy made some serious cash"
Take a look, I think you will find "he" is a lot better looking then you might imagine. Enough, perhaps, for some divorce-proving thoughts?
Going to try an SSD...
In my case I am thinking of using it as the journalling device for my ext4-formatted HDD RAID array, that might help a bit in dealing with write speed on big-ish files while keeping the redundancy of the RAID.
Might also try it in due course as a ZFS intent-log device, if I ever get round to re-purposing some of the HDD I have accumulated in to a high integrity data store/backup thing.
"specifically so that actors lips move at the same time that the sound reaches the viewers ears"
I expect that delay is the opposite way - you delay the video to account for the audio's slower path.
The real problem is for the actors & musicians who need to play in time with each other, and if you remember the joys of significant delay on a phone, it can be very disconcerting (pun?) to hear yourself with a modest delay.
What Ofcom has finally been forced to recognise it seems is you can't magically replace a high power FM link and get the same near-zero delay and hi-fi sound in a GSM channel, and so live events need to have much more bandwidth (and protection for it) than a similar number of phone users.
The issue behind the shift is simply money - they wanted to combine and flog the analogue TV spectrum for money. Ah yes, analogue TV, I remember when it was near real-time for the New Year bells and where you did not get blocky compression artefacts on anything fast moving. Just needed a decent SNR...
Re: The weakest link
You seem to have missed the point, it is not latency for "live" broadcast on TV - that is bollocks, it is latency for things like concerts and theatre where you can't tolerate 0.1s delay between actors & instruments, etc, and those involved are experiencing it all in human real time.
All of the bandwidth/power gains you see with digital radio come at the expense of delay - you need to have a significant block of data (10s of milliseconds or more) before you can strip out 'insignificant' information for audio compression, and similar case to allow the addition of worthwhile forward error correction (ARQ is largely a lost cause when real-time matters, and most radio mics, etc, won't have a back channel).
Did that once...
Have a Linux box I was going to wipe & re-install so thought I would try basically the above approach. Was quite surprised how far it got, eventually all of the text vanished from the Gnome desktop being replaced by small blank boxes (guess that was the fonts gone!) and finally it froze. Rebooted with a live CD to inspect the file system and only a handful of directories still existed (those with open 'files' before it finally stopped), but not any files as far as I remember.
Was impressed by its thoroughness!

Re: So they know where I am and what I'm doing
Often I run Facebook in Chromium without an ad-blocker just to see how, and to whom, am I being whored. It is interesting to see how they move towards dating adverts as the evening progresses. I guess that tells me all I need to know about my sex life.
The fact I am looking at Facebook late in the evening, that is!
Re: Time Legacy.
Think of how much effort would be saved if software developers just implemented time sensibly? It is not like this whole world timezone & DST issue is something that happened after computers were developed, is it?
Sadly you are probably wrong and this is simply a software screw-up.
So much of MS (and presumably Adobe?) software did things in 'local' time and often without making clear what zone that was. That was just brain dead. What is worse, they assumed that the clock was in Microsoft's home time zone, not UTC, if nothing was specified.
The reason for being able to say its crap is this was already a solved problem before MS-DOS and Windows was created, as UNIX always uses UTC as its underlying time and just applies the local offset for presentation. That way when DST changes, or you access a LAN from another timezone, you still get the correct (OK self-consistent) times.
Re: Headline is flawed
All 'operating systems' have flaws, some more than others and some patch easier than others, but we get used to the idea that every so often (and that is usually <= month) we get some minor update to fix problems and close vulnerable orifices.
It is just a shame that phones, which now run as full and operating system as one could imagine, seem so utterly crap at being updated. Not just the the manufacturers don't seem to care much (thinking of you, HTC) but even when they do offer a patch it is often of the "save your settings and factory wipe" the phone. The sort of brain-dead approach when Windows95, etc, got upset all those years ago.
Why have they not learned from desktop OS that patching is, sadly, inevitable so make it something that is easy and (normally) automatic?
Yes, I know of diverse hardware but that is something that should be well within the capabilities of the manufacturer to have automated build/test setups. And yes, I know of the crapware some telcos add to a phone, but again that should be unimportant for OS patches as that is stuff that (should) runs on top of the core OS.
Was going to add your point - if you want to enforce OpenDNS you also need to configure the router's firewall restrict port 53 to only the OpenDNS IP addresses (18.104.22.168 & 22.214.171.124) which some, but probably not all, home routers can manage.
But it is true the setting up a home router to implement this properly & securely is not trivial even for a reader of El Reg, let along Joe Public.
I also made in my submission the same point raised by Ken Hagan about what exactly should be blocked? Who decides and monitors this?
The consultation asked about 'blocking' but gave no indication of what would/should be blocked, and how much it would cost us, and who would pay when (not "if") it screws up and the innocent are blocked. Thankfully sense has prevailed for now, and they (the government, not necessarily certain MPs) appear to have canned the idea.
Point your home router to OpenDNS and set that up, easiest way to control all home devices on DHCP. Otherwise you get in to per-device configuration, either OpenDNS again, or filtering software and with a typical range of devices (Window PC, iPad, Android phone, etc) you won't get any software uniformity for filtering and a whole life of pain in tending to them.
Better still, talk to them and educate them about the risks on-line. Not easy to do I accept, but much better for their long term development.
Re: Rebuilding a Speccy...
I think (but don't have clear memory or facts) that the ZX series were cheaply made and used a double-sided PCB and not multi-layer boards with power & ground planes. That, if true, is probably the #1 reason for the poor EMC performance.
Also note they tested it without cables/peripherals, so real-world use would be significantly worse that observed in El Reg's article.
EMC who cares?
Really, the BT power line modems are also an abject EMC failure but due to the money behind them ofcom, etc, don't care. The solution? They re-draft regulations to allow more noise...
The key point is once you have licensed a VM (which for XP is fine though Win7 I think muddied those waters) is you don't have to worry about hardware changes, drivers, etc. Further more, if it is running in more-or-less isolation for specific tasks you have far, far less to worry about in terms of security. To the point where I don't care about my XP VM going out of support in a year or so time.
The manage-my-whole-network by Microsoft is very attractive for corporate users, and so far Apple & Linux are not nearly as organised, etc, but most people don't want Windows, they want stuff that works and gives them less trouble.
And MS don't really get that - they foist Metro [insert latest name here] and the office ribbon, etc, on us without the obvious and easy to implement option of just keeping the old way and that means re-training and so on. Change is annoying, and it is gradually getting to the point where going from MS to MS latest is as much trouble for users as going to an alternative.
OK, Ubuntu et al are not doing themselves much favours either...
Re: Game changer
The first point is that this always-on encryption means that they can't just seize the servers and go trawling (or trolling?) for evidence. They have to take you to a court and show good reason for a judge to compel you to hand over any password in your possession. At least you know they are investigating you and have recourse to legal advice early on, and the sheer effort of going after someone through the courts means they simply can't afford to do it for anything other than serious and significant cases. A few bootleg episodes of the Simpsons, etc, is hardly going to be worth it and copyright trolls (like the now defunct ACS:Law) will find that as well.
Second point is if you have forgotten your password, I think the ECHR would come down on them for any attempt to force you to reveal what you no longer have. Of course, if you were dumb to say you know but are not telling, or if a court might not be convinced of your genuine problems in remembering it, then its not going to work.
Third point is how long will it be before someone has a third-party service in another country that manages the passwords and can be set to destroy them if not used for a couple of weeks, so unless they can go through the courts very quickly (again, meaning you have to be on a really serious charge) then there is no longer a password to be revealed, as your memorable one will no longer recover the encryption one.
I would be amazed if even 33% was actually unique and valuable enough to protect.
Well she ate his little head, and that is where a lot of men appear to keep the controlling brain.
Competing app stores?
What is really needed is someone (e.g. the EU) to force Apple, Google & MS to allow alternative public app stores to be added under YOUR control, so you get real competition, and are not simply reamed by your OS supplier having bought a device.

"Just think of all the jobs that are lost"
By these big-name companies moving manufacturing to the far East for cheaper labour and using IP laws to defend high prices and blocking 'grey imports' of genuine goods at lower prices?
Think Tesco vs Levis anyone?
CD Wow! versus BPI perhaps?
A key problem here is a lot, in fact almost all, of existing control systems were NOT designed to be secure enough to have world+dog probing their nether regions over t'Internet. Even when bugs are found most operators are loathed to change a fully commissioned working system due to the risks of other unexpected side effects, the possible lack of current personnel fully understanding an older system, and the difficulties of testing everything on a safe simulator/system before you go live with it.
With expected life times of 10-20 years do you really think they will replace them sooner to fix the deep seated design problems, or just ignore the risks because its the "done thing" in this new business model?
Re: "Redmond has produced a turkey this Xmas"
I would be less disturbed is you had said turkeys can be tasty, instead of "very useful".
"If it does the job, and with a lot less cycles than ZFS, what is the problem?"
The problem is no integrity checking, same issue for Linux software RAID, etc. My data is valuable, so I want to know if it is uncorrupted, and this is something I have seen before.
"Why does Oracle Linux use OCFS2?"
Because ZFS' license is not compatible with the Linux kernel's GPL one, resulting in it generally being relegated to user-space where performance sucks (same for all other fuse systems). This is a legal issue, not a technical one.
"ZFS is just a ripoff of WAFL"
Hmm, I think the NetApp versus Sun/Oracle case was closed on that one after several of the patents were struck down. Odd you see that as a problem, as NetApp's customers like things like snapshots and copy-on-write. OK, they don't like the usurious license fees NetApp like to charge to actually *use* such features, but that is a separate issue.
"It also has problems with hardware RAID"
Not really, but if you use hardware RAID, or a separate software RAID layer to present the storage to ZFS, you then lose the key advantage of error detection and recovery of 'silent' HDD/bus/memory errors that most dumb RAID systems miss. It will at leat tell you the file(s) are corrupt, but too late to do anything by then.
I have wondered why you have such a problem with anything Sun-related, as your other posts on DB stuff are clear and rational. So why are you not so caring about data integrity in a storage system? What do you uses/recommend to verify data is exactly the same as when written?
The problem with simply monitoring the SMART status is it won't know about bad sectors until you try to read them. Often by then it is too late.
Smart has support for a surface scan, and while that allows marginal ones to be re-written, it just report any uncorrectable/re-mappable sectors as bad and you won't generally know about that until a HDD fails and you need to re-build the array.
Hence the advantage of the RAID scrub process:
1) It accesses all of the HDD sectors (or all in-use ones in the case of ZFS), forcing the HDD to read and maybe correct/re-map any that are marginal, just as the SMART surface scan will do.
2) For any that are bad, it, by virtue of being in a RAID system, can then re-write any bad sectors with the data from the other HDD(s) and that will normally 'fix' the bad sector (as the HDD will internally re-map a bad one on write, and you still see it as good due to the joys of logical addressing).
Recent Linux distros like Ubuntu will do a RAID scrub first Sunday of the month if you use the software RAID, which is good. But I don't know of any cheap NAS that pay similar attention to data integrity.
Not counting RAID-0, OK?
One critical issue in my view is data integrity. That is what a NAS it supposed to do, store data reliably. But the article fails to address that. Do they support internal file systems that have data checksums (like ZFS)?
If not (and important even with ZFS) do they support automatic RAID scrubbing where periodically all of the HDDs are read and checked for errors in the background.
Most folk at home will only have 1 HDD of protection (RAID-1 or RAID-5) and what happens later in life is a HDD fails, you replace it and find bad sectors on the other disk(s), thus corrupting the valuable data. With two HDD of protection (e.g RAID-6 or ZFS' RAID-Z2) you can cope with one error per stripe of data while rebuilding, but that is not always enough.
That is why you want to check once per fortnight/month that the HDD are all clean, and so so allow the HDD to internally correct/re-map sectors that had high error rates when read, and if necessary to re-write and uncorrectable ones from the RAID array if that fails.
Of course, sudden HDD failure happens, maybe even multiple HDDs, or PSUs, as does "gross administrative error", which is why you should all repeat "RAID is not a backup" twice after breakfast...
Re: not enough bays
Seriously, you think that a home/small business internet connection can support access to 20TB of data in the cloud?
" I can get built-in RAID on most PC mobos" - that is almost certaily 'fake RAID' where the BIOS can boot from it but it is the OS that has to actually do the RAID computation. OK for simple RAID-1 or similar its easier than ZFS, but it still lacks the advantages of data checksums.
ZFS is not the only file system that does that, GPFS has them as well, but most others I think only do metadata checksumming (e.g. Linux ext4, and MS' new and unproven RsFS unless you explicitly ask for the extra checks/load).
I can't believe you have not ever had that horrible feeling when you get a/multiple disk errors and no simply way to find out *what* has been corrupted by the failure of "sector 102345569" etc. Also I am not the only one I know to have had data corruption in a file system due to bus/memory errors that were 'silent' so it was only on decompressing a ZIP archive (which has integrity checks in it) that it was discovered. Most other files have no checksums so the true extent of the damage was not known and the tedium of complete backup restoration had to be undertaken.
We all know you have an irrational dislike of all things Sun, but from an integrity point of view ZFS is one of the best choices for file systems, unless you are playing big-league with IBM's distributed system.

Indeed, the question remains for everyone outside the USA (and hopefully some inside) is do you trust Intel/McAfee?

I'm no expert, but I think Mars once had a decent atmosphere but something happened a long time ago to kill the planetary dynamo the provided the magnetic shield to stop the solar wind stripping that away. Now we see little of what was once there.
Remember Venus is the same (approx) gravity as the Earth, but has a *much* higher atmospheric pressure.

Re: Charles 9
The DRM aspect is why it is so important to keep TPB afloat - so they learn that DRM is bad for *paying* customers and the pirated sort is a better experience, you know, the sort you would actually prefer to pay for.
It took years for the music industry to accept DRM-free once the realised that the battle was lost and that the majority of customers, when treated nicely, are happy to pay for content.
So far we may have got past the "you are probably a thief" non-skipable crap with DVDs, etc, but we don't have freedom legally to use media on any platform we want and to skip crap like trailers as we wish. The move to HD and streaming is a new battle ground for DRM and it must be the public at large that wins this one, unless we all want to be digital sefs to the few biggest of corporations who hold the DRM-forged manacles.
Re: How much ....
Because you are paying someone else to do it.
In theory you get reliable operation and nice management tools, but in practice you often get a plate of donkey gonads to suck upon.
Re: AC 15:24
Microsoft's FAT32 patent is a very bad example, the reason no one else did it earlier was IT WOULD NOT WORK WITH WINDOWS until Microsoft did it their way.
No one in their right mind would choose to do thing in the FAT32 way unless they have to work with MS software, and their oligopoly status means you have to.
This is an example of why patents need reigned in - where you can't interoperate without infringing. The basic idea behind the patent system is good, the problems I have are those already stated, that the may be:
not very inventive
needed for interoperability
too long lasting in areas (e.g. software) where 20-25 years represents many, many generations of a product.
OK, that explains something and makes more sense. I had assumed this was an extension of the device driver signing process where they did look at your code.
One way mirror?
So am I right in assuming that to get approval MS get to see all of your 'trade secrets' of your source code, quite possibly to copy (sorry, "influence") for new MS products, but you don't get to see theirs?
If you have to bare all, at least go open-source and maybe get community help in bug-fixes, etc.
Re: Not as cheap as it sounds
Just read the blurb:
"Secure – Amazon Glacier supports secure transfer of your data over Secure Sockets Layer (SSL) and automatically stores data encrypted at rest using Advanced Encryption Standard (AES) 256, a secure symmetric-key encryption standard using 256-bit encryption keys. You can also control access to your data using AWS Identity and Access Management (IAM). IAM enables organizations with multiple employees to create and manage multiple users under a single AWS account and to set resource-based access policies."
So basically they encrypt the "tapes" (we presume they use tape ultimately) but the still have access to your data, i.e. it is not encrypted at your side, using a key that only your company has.
Bend over Blackadder, its PATRIOT time!
Re: Not as cheap as it sounds
For a small user at least you save the cost and maintenance of the tape drive, and the off-site storage of tapes in case of major local damage, etc, which makes it attractive.
But the lack of any obvious way to control the encryption yourself (unless I missed something) is not good.
Re: Hmm, where do I put all my sensitive data?
The only sensible option is to encrypt the data with *your* key before it gets to them. Of course that usually buggers up de-dupe and always buggers storage-side compression, so they won't like that being the norm.
Considering the other problem, that of up/down link bandwidth, you would really want to compress/de-dupe your data before considering backing it up, which would help them as well. Not quite so simple to use properly then.
Re: Whatever is bad for Microsoft is good for everyone else.
I up-voted you because some of what you said is true (i.e. we need more and real competition for the mass buyers of computers), even though I suspect you need to keep taking the dried frog pills...
Re: Is this really an issue?
"A surprising number of companies were still using 16-bit installers that should have been done away with a decade earlier."
Assuming they do/did a proper job that the business needs, why should they not be supported on 64-bit as for 32-bit OS?
The idea that *working* software has to be replaced simply because the OS supplier can't be bothered to support it is a worry, and is the best argument of all for going open-source where you have the ability (or paid contractors can) support legacy stuff if it is cheaper then throwing away years of experience and bug-fixes in the pursuit of 'shiny'.
Re: Your rival may get many more viewers by NOT banning it
There are no rivals - except the pirates, and of course then you don't need all of this technology to 'allow' you the watch the stuff you just paid for, you can watch it anywhere.
Really, in a number of ways I support the TPB simply because the low bar to accessing 'pirated' material has, or hopefully will, make the content industry realise its not so precious after all and that if they want my money they have to make the experience of legal purchase easy and effective for me, on any of my devices.
Does any one out there really want stronger DRM to be baked in to the hardware and further restrictions on what you can and cannot do with YOUR hardware becoming the norm? Screw you Apple!
What metadata should be protected?
The idea that removing any metadata should be stopped is a dangerous one, as it could lead to images being attributable to people who really don't want that in public (e.g. photo of a crime, personal adverts on dating sites, etc).
What is needed is some sensible machine & human readable metadata for copyright that is protected by law, and maybe some hash of the rest (date.time, camera settings, GPS coords, etc) if it is missing. That way images' ownership can be traced as needed, but are not identifiable so easily unless the photographer applied their public 'signature'.
Do you really want all of your data locked to the CPU, so if your machine dies and you swap the disk to another it is all unreadable?
At least with an iPad there is no real expectation of recovering data/physically upgrading if it has failed (or stolen, as likely), and their whole software model is based on cloud backup.
And yes, you probably should have a backup of your PC but we all know how easy and regularly done that is...and how successfully and well tested the restore process is...
It is not pointless because:
1) It makes Joe Public realise that this is OK and sort of MS-approved, and is safer than a random download.
2) It gives other browsers a chance, and not just Chrome that Google push relentlessly on their home page.

Re: What a ridiculous situation
the market condition that exists when there are few sellers, as a result of which they can greatly influence price and other market factors. Compare duopoly, monopoly
The point you are missing is this is not about corporate users for whom a sysadmin sets up the approves configuration, nor for readers of El Reg who fully understand how to install other browsers and/or configure search engine choices.
This is about Joe Public who can't tell the difference between an address bar and a search engine, and for whom the blue 'e' was "The Internet". Once most of them are using an OS-specific browser you get the stupidity and lock-in seen, for example, in a lot of South Korean banks where you need an ActiveX plug-in for on-line banking.
And so you can keep your hands tightly around consumers genitals and squeeze them for all the money you can with little chance of them moving way from your cash-cow.
That is what the EU has acted for, and given the size of MS and their inability to keep a promise, I don't think 10% fine is out of the question. Please educate yourself on the whole anti-trust proceedings that started with MS moving against Netscape before arguing about it.
