Re: I'm so excited
Hmm... you seem to have forgotten "and I think I like it"
Though judging by your last line, perhaps not.
Re: Should be doable
Just break the encrypted files down into small enough chunks and you'll find dupes
If it were that easy, you could just break it down into 1-bit chunks. But that obviously requires a bigger index than the original file collection. (Q.E.D. by Reductio ad Absurdum). Random data (such as the output of a good encryption algorithm) by definition are not compressible.
Re: Deduplication, how?
It doesn't seem likely, does it? There's one type of encryption (homomorphic encryption) that in theory could work, but in practice it won't. I won't bore you with details of that.
The solution I would use would be to set up the front-end of the storage system to use an all-or-nothing transform (AONT) on the files, break them up into blocks and then distribute those blocks in a random order, with a single encrypted "key" being the locations and order of those blocks. So long as nobody can break into the fronted computer (or instruct it to divulge how to reconstruct a given file) then the storage is secure. Since the AONT should produce the same blocks for the same input file, you can do block-level dedup on the actual storage servers. I'd then encrypt the access key, add some validation info and send it back to the user before deleting it.
Of course, in this scheme, you (as a user) can't trust the server not to keep the access key or to make a copy before it's encrypted, and so on.
Gah! Enough with the downvotes. I get it. I know, it's something I'll have to take up with my the- rapist.
They really called those things rapey-scans? (that's how I'd pronounce it, anyhow).

I got an Odroid-x and the hidden Fedex charges put it to > £120.
Similar story for my X2, but I did what the hardkernel website suggested and called my local customs office before placing the order. They told me about the extra "customs clearance" charge that Fedex adds in. I guess that hardkernel could have done a better job on pointing out the surcharge that Fedex puts on it, but I can't fault them on their advice on contacting customs. I still went ahead with the order once I knew about the extra costs. Well worth it, I reckon.
As for Atom vs ARM systems, I actually did a bit of window shopping before ordering the X2. To be honest I couldn't actually find any Atom systems that were as good or as cheap. The one thing that the bare-bones Atom systems did have going for them was standard (mini) ATX and SATA ports for upgradability. They're still quite expensive compared to the ARM boards. Also, buying a cheap 2nd hand system was out for me because I was looking for something with low power usage and you don't get that with older Intel/AMD/Atom stuff.
I guess that in the next year we'll start seeing more ARM SoC with SATA, USB 3 and gigabit ethernet since there's definitely a market for it. Until then I can definitely live with flash/USB2 and 100Mbit ethernet.
An mk808 is less than half the price, runs a newer version of android and is WAY more powerful.
I'd never heard of it, but the link you gave puts the mk808 at $58.99, which isn't "less than half the price" of either the Rock ($79) or Paper ($99).
Now the ODROID-U2, on the other hand, costs $89 (*), has quad core clockable to 2GHz (base 1.7GHz) and 2Gb of RAM. Also runs Jelly Bean and Linaro Ubuntu (no accelerated X yet, though it's expected in a few weeks). Its sibling product, the ODROID-X2 is very similar, except that it costs $135 and has a whole lot more ports.
(*) as with a lot of these boards, power supply, cabling, flash drive and shipping aren't included. A full U2 ends up costing about $150 (including a hefty $40 shipping fee from Korea), plus local customs clearance and VAT which brings it to something closer to $190. Definitely pricey compared to a Pi (which comes to around €72 all told), but the U2/X2 are are at least 12 times more powerful in my tests (thanks to 4x cores, 2x speed, step up from ARMv6 to ARMv7). So while the Pi definitely wins out on price/system, the ODROIDs definitely win out on performance/price IMO.
Re: It's not all good though
I think the word you were looking for is 'depilation'.
The way I misread that ("delepidoteration"), I thought he was talking about getting rid of butterflies.
busy OLTP database server
Although I don't have any direct experience with this, it seems that a lot of databases aren't well suited to using flash storage due to them not being optimised for that medium. The problem lies in the way that inserts and updates often have to make several updates on the on-disk indexes (B-trees or whatever) and each random write requires a read-blank-rewrite cycle on an entire disk block. Reads from the database, on the other hand, is something that does suit flash well since seeks are effectively free.
I don't have a link to any recent papers to hand, but if you search for "log structured database flash" you should turn up a few. The main advantage of log-structured databases is that inserts and updates only have to write once to the disk (with periodic rewrites for garbage collection to coalesce partially empty blocks). Thus you get very good write speed and since you're not going through as many of the read-blank-rewrite cycles that are typical of B-tree style indexes you should be able to extend the life of the disk by three times or more. Have a search for Fast Array of Wimpy Nodes (FAWN), too. It's slightly old, but it gives a good demonstration of the kind of speedups that log-structured databases + flash storage can achieve.

Re: A bit of a spanner?
re: Ah. Passers by asking people stupid questions of people who are taking pictures in the street.
I disagree... I actually got quite a warm feeling on reading that part of the article. Nice to see that a passer-by would take the time to see if he was OK. And lets face it, taking photos by spinning around probably does look a bit crazy if you don't know what's going on.

Re: 6/8 time...why not 3/4 time?
Apparently it's down to the fundamental note length not being 1/4 note, but half as much again, ie, 3/8ths (a dotted quarter-note in sheet notation). Three/Four time is typical of waltzes and has a ONE two three and ONE two ... beat structure, but I'm not sure how to describe how 6/8 time sounds, or even whether it necessarily has a fixed place to place the emphases.
Anyway, while reading this article, quite a few thoughts came to me. Several posters have brought some of them up already, but not all..
re: the xkcd strip... is the word order even right in that?
re: "kiss this guy" I believe (I read it somewhere on the Internet :) that Hendrix became aware of this mishearing and on some occasions actually sang the modified lyrics. Certainly one time I saw him on a BBC program it sounded more like "kiss this guy" than "kiss the sky" to me. Also, this:
I loved The Smiths, but lots of their lyrics were indecipherable to me... "horn-shoed bicycle on a hillside desolate???" And forget about My Bloody Valentine....
Getting back to time signatures, I hope you mentioned Time Out by the (sadly) recently-deceased Dave Brubeck. While he didn't write the famous Take Five with its 5/4 time signature, all the tracks on the disc have unusual time signatures. It still sounds great today...

Re: I still don't get…
Apple and Linux representing diametrically opposed design philosophies
Exactly that. Linux carries on the free and open aspect of Unix history, while Apple carries on the parts with all the litigation over copyrights, trademarks and such. OK, so the latter isn't actually anything to do with Unix as such, but it's a problem that has dogged Unix-like systems ever since people realised that it is actually valuable. At least Linux (and I guess the free BSDs to a lesser degree) managed to make most of the legal wranglings moot, apart from the SCO issue.

Re: excited states apparently exist in a contiuum between quantum states
that kind goes opposite to the meaning of quanta, doesn't it?
Yeah... "fractionalised quantum states" had me my scratching my head too. At least the article does a good job explaining why it's weird (and controversial).
Or to mangle a Billy Bragg quote... "something that every football fan knows, it only takes five fingers [if you include an opposable thumb as the fifth, it seems] to form a fiiiist"
Re: Counting spiders
Seems unlikely they could count to 8
Maybe they can count to 256?
Re: So, presumably
I don't think it needs self-knowledge
I'm not disagreeing with this, but I'm not sure you can completely rule out the idea that the spider is "deliberately" making something in its own self image. I'm not suggesting it has self-cognition (some insects and arachnids have brain cells running into the dozens, from what I read), but I don't think it's crazy to suggest that spiders can have a sense of proprioception (ie, knowing roughly where its limbs are) and that that might form the basis for setting up a feedback loop (from cybernetics) to explain the how of what it does, if not the why.
It would be pretty amazing to find that if could use visual information, but I'm guessing that proprioception could be a sufficient mechanism to explain it. It might even be possible to test the theory by filming the thing making the shape. If it makes leg waggles that correlate with the order that it builds the legs on the model then maybe the theory itself (to pardon the pun) has legs.
Just throwing this out there. IANAEB (I Am Not An Evolutionary Biologist).
Like when atheists point at parasitic wasps as 'proof' there is no God? Equally weak arguments.
For some strange reason after reading this exchange I had the image of a little spider cackling maniacally and then booming out "Where is your God now?!"

Upvote for saying what I suspected, that you have to have the YEAR in front. Not only that, but the got the poster delimiter wrong too (slash instead of dash).
For some reason it really bugs me to see web pages using the MM/DD format for things like, eg, release dates. You have to figure out if it's just another typical USA-ism. It's not just the date format, which I guess their entitled to, but the fact (calling it this based on prima fascie evidence) that they never bother to think that they might have readers outside the US or that they might do something different there.
Whenever there's any doubt I always try to spell dates out as YYYY-MM-DD (props to Japan for having this as their standard) or spell out the date ("21st Dec" or "Dec 21"). And of course for anything computer related (eg, file naming) big-endian YYYYMMDD is almost always the correct order (adding dashes to taste).
Anyway, what has all this got to do with 4?

Re: Ummm... this is a MODELED finding?
Oops. I just reread the article and I see the point you were making about greatly reduced costs. It was late and I guess I glossed over that entire sentence/paragraph just reading is as "all without government subsidies". Sorry about that.
Still, I'm heartened by what another commenter said above that the assumptions might be reasonably realistic for the US states the model was looking at, even if it's probably not applicable here in the west of Europe. It's nice to get some positive news on this whole issue, even if it is only applicable there.
Re: Ummm... this is a MODELED finding?
I'm not sure if this is how they did it, but when I read "28 billion combos" my first thought is that it's probably easy to arrive at this solution by using a genetic algorithm. Probably more likely that they had some big, un-environmentally friendly compute cluster brute-force searching the entire solution space, though :(
I'm not sure how to react to your criticism of their models, to be honest. Yes, models can be unrealistic, but on the whole I'd rather have them than not. Then you can start picking apart the basic assumptions (the one you mentioned "renewables will drop greatly in price" wasn't even in the article text, so I don't know if you're just making that up or not) or otherwise criticise/falsify it. But to what end? Just to be negative, or to make a better model? In either case you can't criticise a model just for being a model...

Re: Your title is too long!
re: needing extra incentives to make Linux versions, I think that actually it shouldn't be that much of a burden to most developers to add Linux versions to an existing roster of Windows/Mac versions. The key, really, is that once you've got an OpenGL version working for the Mac platform, you won't need to do much to port this to Linux. After all, they've both got a fairly standard Unix heritage (not that most games use the OS for much anyway) and both have industry-standard OpenGL. The biggest problem is the variety of graphics hardware that Linux users might have driving their displays and what level of OpenGL the Linux drivers support, but that's really more of a problem for the users to sort out: if they want to be able to play games, they know that they have to shell out for decent graphics cards and do their homework in terms of checking whether the card is properly supported and being prepared to delve into the forums when things don't quite go to plan. If anything, it's the state of graphics drivers, though, and not Linux itself that is the main stumbling block for users. The graphics card manufacturers really need to do a much better job with its Linux drivers...
The real question is whether the market exists for Linux games. I think that there have been signs from a long way back that Linux users would love to have native games for their platform, and even that they'd be willing to pay a premium for them over the Windows versions. Like "Linux on the desktop", though, it always seems that proper gaming support is always 2--3 years off. It's very interesting to see this new Steam development and, to a lesser degree, the way that OpenGL (ES) has become the de-facto graphics tech on the various mobile platforms. I think that if things continue along the same arc, we will begin to see a lot more of a market for Linux gaming, though I think that the actual OS will not be as relevant as the division between games designed for DirectX, OpenGL and OpenGL ES.
Re: more than apps
The reality is, almost all the main Android apps have tablet layouts included in the APK.
Yup. I see this line or variations of it, such that Android layout looks shit because its too hard for developers to code for the myriad screen sizes (and orientation). In fact, if you've ever looked at the UI design parts of the Android SDK, you'll find that they have great support for tailoring the look of your app to differing screen sizes, and probably (like me) find it easy to understand and implement UI design using the SDK. In particular, they define various constants relating to screen size, dpi and relative icon size and so on so that you can either dynamically reorganise your UI at runtime, or pre-bake a set of default UIs and then select the one that's closest to the properties of the physical screen (or do a bit of both, if you wish). If you want to delve a bit into OpenGL, you can also create a mipmap for each icon and then interpolate to the correct scale, or you can just provided a set of fixed-resolution images and let Android select the best one.
More recent versions of Android (3.0) and up also have the idea of "Fragments" to make dynamically-scaled/rotated UIs even easier to build. More importantly, though, they make it easy to radically alter the UI layout depending of screen size and orientation, say by presenting a two-panel display on a large, landscape tablet, while omitting less important options (relegated to the action menu) from smaller or portrait displays.
As for the specific claim that media delivery is scaled up, you're surely having a laugh, right? Surely "media delivery" just means playing a video, and I can't imagine any media player that can't handle matching the video stream dimensions to the physical screen dimensions? Ludicrous.
Re: what a stupid article title
So a cheap attempt to shoehorn a humorous cultural reference trumps scientific and historical accuracy? Monty Python's Galaxy Song shows that it's possible to be (truly) funny and (mostly) accurate at the same time. This? This wasn't even funny enough to gloss over the inaccuracy, especially considering that there are nutjobs out there who literally believe that we did live alongside dinosaurs at one point. That definitely moves it into "unfunny" territory for me. It's supposed to be a bloody science article, for god's sake, and that headline just turns it into a puff piece.
what a stupid article title
What on earth has Fred Flinstone got to do with anything? That headline suggests that (somehow) evidence for dinosaurs and humans not only living together, but of humans domesticating them! Jeez. I'd expect that sort of tripe from some nutjob religious sect--not the Register.
Re: Said it before and I'll say it again
Maybe pay for the full version of the software you mentioned?
I've never used either of the apps you mention, and I don't know how much the full version(s?) costs, but surely if it's that useful to you it's worth paying for? If you can afford the transformer prime, I'm sure you can afford another $20-$40 (or whatever it costs) for software that you know you want... (but seems to be too cheap to pay for).
OK I don't mean that last comment to sound nasty, but seriously, if you're an Android fan and you want it to succeed, you could at least support the developers of the platform by buying the app. I know it's easy to have the mindset of wanting all your software to be free, especially if you've got a background in Linux or one other other free "Unices", but from what I've seen most of the Android software is pretty reasonably priced.
If you're still dead set against paying for something, you can always write it yourself. I think you'll find it'll cost a lot more than just paying for an app that someone's already developed, though.
