I can see the efficiency of block level sync, and ZFS support replication using the same principles, but my own paranoia is that a software/firmware bug on one that trashes file systems is then block-replicated to another much as RAID would do between disks.
While that is a low probability, it still makes me happier with the option of making snapshots and syncing the file system across. Of course, no gain if you are using a block-style access (iSCSI or raw database sort of thing).
Re: Synology Issues
It is odd to see how a NAS could break the disk short of a major overheat.
However, I have had a number of 1TB Samsung HDD die on me, typically they would go off-line (SATA time-out, even SMART not showing status) and need a power cycle reset then come back with all data OK, but the up-time was getting shorter and shorter so I swapped them for other HDD and let the RAID rebuilds deal with it.
Re: Too late
"In the end they got Vista more-or-less working properly"
Yes, and then they sold it as Windows 7 rather than upgrading the poor suckers who had been visted.
You seem to be mistaking stealing, where you deprive the owner of their property (a criminal act), with copyright infringement, where an unauthorised copy is made but the original is still there (a civil act).
You also seem not to have comprehended that this was about saving a copy of a video stream that, I am guessing, you already paid for. So it is not even depriving the copyright holder of revenue, but simply doing what is perfectly legal in other cases (see the judgement(s) in respect to the original VCR use) and what most people see as "fair use".
That "three line post" is but a continuation of the same tedious vague claims made by (most probably) the same AC over and over again.
Just as tedious as those who claim Linux in invincible to every Windows hole found.
Re: admin admin
Most folk are not El Reg readers, they just buy some modem thingy from the local store and plug it and it just works! Great!
Of course, no Wi-Fi password and default admin log-in, but why make it hard for your users then would have to support them?
Re: @ AC 14:14
Ah yes, a report from 2010 is conclusive evidence of Linux vs Windows today?
And did you actually read it?
"But should be the out-of-date Linux server the only reason of this huge amount of defacements?
Yes and no.
We were talking about local kernel exploits, but the first problem is in the website code. For example, we received too many single defacements due a remote upload flaw in OsCommerce CMS, that allows the defacers to upload anything to the CMS folder without a proper credential check. When this flaw became public, the developers had a too much time to fix it, but the fix appeared few months later. Pity.
Year after year, the developers are still coding by an unsafely, keeping tons of the remote and local file inclusion and the SQL injections, that the attackers use as the first step to gain the access into the server OS."
That read to me as if the web developers and tools are the biggest part in such attacks. But hey, you don't care when having a good rant?
True, 1080 is not that much, but:
(A) This is a £340-ish thing, not a near £1k ultrabook with piss-poor 900 lines.
(B) There is very little above 1080, some monitors have 1200/1440/1600 but cost £300/500/1000 sort of price for the monitor alone.
Overall I am impressed by this and can see it suiting a range of folk for basic computing needs, particularly for the likes of my elderly parents for whom even a 15" wide screen laptop display is simply too small, and for whom paying >£1k for a 17" laptop is just not on.
Re: "refocus on its traditional markets."
I was in PC World recently (UK box shifter of computer & TVs etc) and noticed that there was about 3 times as many customers looking at the range of Apple & Android devices as were looking at Windows laptops, even though the latter has over twice the space allocated to it.
Of course, that may not match actual sales.

Re: Legal liability
I hope this is picked up in the USA as they have class-action lawsuits to make it worth while for the lawyers to go after them for compensation.
Sadly the worst likely to happen here is a ICO slap on the wrists. I hoped the BBC and so on would cover it on national TV, that would be fitting punishment for the company - to have its amoral behaviour aired the way its customers where being aired.
Re: "THat it doesn't work with ARM"
I think this is the point of the cynicism. MS so much want people to support WindowsRT and then can't be arsed to do it themselves, that says a lot.
Don't buy Cisco, Extreme, 3Com, HP, or Intel gear.
Really, they gouge you on everything they can, to the extent of locking out rival SFP units "because they can":
If they had a supported list that included any rival's products then you might have believed the quality assurance bullsh*t...
The point is?
Really, when the US gov can ask in secret for the data and pretty much compel any US-related business to comply, what is the point in them huffing and puffing and putting in SSL links that, most likely, use a certificate that is from a potentially compromised issuer?
The issue behind all of this is judicial oversight, or more precisely the lack of. We, the public, should expect privacy unless there is "probable cause" for investigation, and that should be properly signed off by a judge after considering the supporting evidence and not rubber-stamped en mass and in secret.
Fix that, USA, and maybe some trust will return. Until then everyone should treat all USA-based companies as fundamentally compromised.
Do they also allow you to export all your data on to HDDs to move to another provider if needed?
To add I that used: https://www.ssllabs.com/ssltest/index.html
I tried online-business.bankofscotland.co.uk and while it got an "A" overall as it used 256-bit AES on modern browsers, it also got this:
"This site supports only older protocol versions, but not the most recent and more secure TLS 1.2"
Looking further, it lacked both 1.1 and 1.2 so no BEAST attack mitigation.
Re: AC 09:45
"You're posting AC, why not just name it?"
They did - read the title of their post.
Oh yes, as a USA company Oracle promise not to share your data secretly and this "may meet regulatory or end-user requirements".
Except of course they have to or executives will face jail time, even if it is hosted in Canada.
Using a VM is a good solution as long as you only need "standard" I/O such as serial ports (on normal Baud rates) or parallel.
If you have any special I/O cards, or rely on something odd in the settings of normal I/O (as I found trying a non-standard Baud rate that the UART chip should support) you are likely out of luck with a VM.
Good luck to them.
Here is hoping they provide what the customer wants.
And that customer is the one buying the machine, not the advertisers and other business hang-ons that have made the new Xbox-one and PS4 such shitty options.
Re: Good Idea!
"I run Windows 7 Pro' 64-bit. It has a 32-bit Windows XP VM to run all that stuff, no further development required"
And what happens to your XP VM come April 2014? Oh yes it goes out of support so no more bug-fixes for the same flawed code that later Windows share. How well protected is your 64-bit system from malware in the 32-bit VM?
Can we have a new 32-bit Windows that is supported?
One that supports 16-bit applications?
One that supports older 32-bit drivers for legacy hardware?
Oh, you just told us that is a waste of space...
Re: Listen to the money men...
That depends on whether you want to make money, and on the time-scale you are interested in.
Re: Good Idea!
"let's drop the waste of space 32-bit versions"
What, you mean the only version that can run legacy 16-bit software that a few businesses actually need?
Oh well, they might as well let those companies invest in dosemu on Linux to get continued support.
It is not a "tiny issue in the grand scheme" if you have to support users who find printing broken after each update, and it is symptomatic of an organisation that, because it is not on their patch, don't care.
But what is most irritating is not them getting the paper size wrong on fresh install, but that each update REVERTS MY BLOODY CHOICE! That is an MS-level of arrogance, to reset my settings without asking me, and for that they deserve a serious bollocking.
Re: What has Mozilla done though?
Not fixing the default-to-US-letter paper bug for over a decade perhaps:
Because the 90% of the world that is not the USA is not important to them?
My sister got an "upgrade" to a separate white ADSL router and black hub/wi-fi point and it is utter rubbish. Often it fails to boot properly (left instructions about how to power cycle the damn thing in sequence to get it working, as they are not technical) and frequently drops both wi-fi and wired Ethernet for no obvious reason.
And while we are ranting about BT Internet's incompetence, twice they have changed the log-in settings for email and given fu*k-all notification of the change, and in the recent case (couple of weeks ago) their web site still had the old=wrong settings on it, only found out from a Thunderbird forum post what was up.
In summary, a bunch of useless idiots with more money & influence than they deserve.
That really is the issue - the x86 Surface Pro makes some sense for business users and others with portable windows needs, you can run most software on it.
But Windows RT has some really annoying limitations beyond what MS give you, and that is what they don't give you. In particular, that mere mortals can't produce desktop-style apps, but MS have that right for IE11 & Office.
Furthermore, you have to *pay* MS to sell your software via the app store, no direct sale/downloads like you can for x86 Windows.
So really, if you want a slick fondleslab look to the IPad (or cheaper & often nastier Android ones) or pony up for the x86 Surface and get proper Windows support.
Re: Still don't see any reasons to buy it
I think you will find "The Register" is not a monolithic Borg, but an outlet for a number of journalists with a varying range of personal opinions.
Yes, I gues.
I am not a software scientist by training but have ended up programming in C (mostly) to solve difficult problems, not necessarily NP-hard, but not easy for the affordable hardware of the time.
Most success came from starting with a good book, in particular Numerical Recipes, and timing where things were held up, for example using the profiling tools that come with, for example Visual Studio.
However, in a number of cases I resorted to approximating the problem or allowing sub-optimum solutions because it was good enough for the system requirements and sometimes vastly faster.
E.g. I once reduced the processing time of some software that re-projected (warped) an image by implementing my own task-aware cache rather than using the DOS/Windows95 FAT system's own one. Today you don't see file systems that inefficient in common use, and memory is plenty big enough just to load the whole source image in to memory for random access, but original case was ~100MB file in the days when you might have 16MB RAM in a PC.
Re: @Alan Brown
Parity & RAID is a bet, based on the probability of multiple failures occurring at once. The quoted figures you get for availability are based on the assumption of statistically independent failures.
We all know that is bollocks, of course. As HDD are often from the same batch so may suffer manufacturing defects, and failure can be provoked by events such as fan failure, PSU surges, etc, that are common to the array.
So RAID != Backup and never forget that!
The trade off with going to triple parity depends on your work load and the CPU/controller, etc, but often it demands larger stripes to be efficient but that in turn hammers the IOPS capability. You can get a lot of that back with SSD for journals/ZFS Intent Log use though.
In most cases you get one failure and then others croak when the load of a rebuild kicks in, in that case double parity is a great help.
But you also get an array being powered off after years of use and a number of HDD just giving up the ghost and not spinning up, at that point you really are looking at a new array and restoring from backup :(
Re: More efficient than the BBC then
No, you don't need a TV licence to watch Internet streamed video. Or to buy/rent DVDs, funnily enough...
Re: Object size & protection?
That was my figure of 1.2 times (or thereabouts), say 6 disk for 5 disk's capacity = 6/5 = 1.2 or with double parity and more disks per stripe 12/10.
Always go double parity if you can, and scrub periodically, as a HDD-failure RAID rebuild is when the trouble starts!
Object size & protection?
I am guessing they don't consider data object bigger than a single HDD then?
Presumably the protection against HDD failure is now based on object duplication, so a 2 times storage penalty, rather then something like RAID-5/6 or RAID-Z2 where you get a 1.2 sort of penalty?
Re: "Ad lobby group, IAB Europe, bemoaned the committee's amendments"
It is sad to see someone believe that "the promotion of innovation and growth" comes from whoring your customers from port to port, rather than developing things people actually need or want to pay for.
"a proper version of Office too"
Er no. Not if you have VB-heavy business stuff based on years of painful Office-based development, which is a big point for corporate users.
Still, aside from the debate about the fundamental usefulness of WinRT, at least Nokia is offering something that looks a viable competitor in battery life, price, etc.
Re: Windows just has a bunch of overhead
Quite probably system bloat, but maybe likely it is due to DRM? Consider this analysis:
Shame none of that protects you, the owner of the PC, from malware...
Has anyone compared XP with Windows 7 on the same hardware to see if this is a factor?
Re: Not in the future...
The sad thing is this attitude, which is by no means uncommon, is really NOT how the majority of USA citizens think it should be.
I have never had a "problem" as such with USA immigration and border control, but as an anonymous person from Europe have seen how slow and troublesome it can be. As a point of comparison when on a flight to Chile, when fellow passengers were actually being fined for failing to declare fruit & veg (in that case a bag of tea), the staff were still polite and pleasant, and no guns were pointed at the visitors during the procedure.
I really wish that the USA gov, and its representatives, could be like the majority of pleasant and helpful folk I have met in my travels in the USA.
Re: You don't need to weaken GSM to give government access.
The protection from "the government" is supposed to be due process and the court of law, which gets its power from the people's choice of elected representative.
Please stop laughing in the back seats!
Re: not allowing rooted or jail-broken phones?
"B) What risks does it prevent?"
Given a lot of "stock" phones will have an OS that is old, unpatched and vulnerable, the only reason I can see is to prevent users from having loaded un-vetted apps from dodgy sites.
However, there appear to be enough dodgy apps from the official site to limit that aspect as well...
Re: Audit the source? Nobody *runs* the source, they run binaries
"with a new version, the auditing needs to be all over again"
That is why you have an automated process, one where the agreed compilers and build environment are used and you can check that the binary coming out of the audit system matches the download version for a given code release.
Then your review of the source code changes is a meaningful activity.
But until the code has been independently audited by cryptographic experts (ideally not from the USA, etc, where there is a justifiable suspicion of court-ordered tampering) it is hard to trust the system, even as compiled from source, not to have either a foolish or deliberate flaw that makes the security much less than the password.
"a TrueCrypt virus. One that only attacks that particular program and inserts a backdoor into installed copies"
Really, you don't think that a simple key logger to grab the password would be easier and more deniable? If your machine has been compromised, even by a user-space program for your account, then ANYTHING you do from then onwards is, by definition, insecure.
"most Android users are quite happy with the Google-backed ROM which comes pre-installed"
No, I think most simply live with the donkey gonad-sucking software that device manufacturers supply and then practically never patch or fix.
Most OS have several patches per *month* for security, when did your phone last get patched? And the only time I got a "patch" for my HTC it was a complete image, thus involved a system reset and having to configure everything again. Look you imbeciles at HTC, Google, etc, patching a Linux-based OS is a know technology, use it!
An image more like a camel's toe under the tent?
"when Microsoft software is offered free, then it's even worser than offering them drugs."
You obviously missed the bit about the school having to be fully paid up to MS, using public money, to get this. You see, that is the point, MS never offers anything for "free", it always comes with restrictions and is simply there to get them while young.
Now MS are a business, and making money is fine if it is done by honest competition and offering the best products. Some of MS' products are very good, but others are not so good and they also have a long and inglorious history of abusing their oligopoly on the PC desktop and OEM relationship to kill competition rather then to make something better.
Re: You can put lipstick on a pig....
Funny how most pro-MS folks are ACs?
To add: I have no love of MS and can't see any special reason to buy one, but younger non-technical friends find the cheaper Nokias are "not bad" as smartphones.
