Re: Yeah right
"Compare performance of two applications once they are actually running and it's good. Compare start-up time and it's often bad."
I have to agree with the OP - i've still not seen any reasonably computationally intensive code, outside of a few isolated routines or synthetic benchmarks, that run anything like as fast using Java over C/C++ or Fortran. Some GUI apps do a remarkably good job and i'm not knocking it as a useful language, especially due to its run-time nature and cross platform support, but once the heavy lifting starts it's a no-go. From personal experience or second hand feedback numerical simulations, search algorithms, things with deep stacks or lots of branching, anything which has significant string manipulation and creation, anything needing any type of time/response guarantee (think GC).. all perform poorly against (half decent) native code.
Java's fine, not without its quirks but what language isn't, but all this continual willy-waving about being as fast as X or native this-or-that is un-necessary and rather obscures it's true strengths (IMO).
'"English English” is an official EU language - but Californian English isn’t. Google doesn’t seem bothered by the distinction.'
-ize would follow Oxford (or Oxford English Dictionary) English - rather than the unfortunate rather Francophile bastardization we use these days (CUP may choose what it will). The irony of much of its current usage being due to the power and influence of a minority - whilst being used in the manner it has in an article about Google must surely not have escaped you Andrew ;)
"..the chance of Google being able to actually develop a better general-purpose chip than Intel is slim."
Although perhaps not as slim as the chance that Google actually want a general purpose chip.
"it's likely the technology will be sub-par compared to Intel or AMD, in terms of raw performance, but the power bill may be low enough to motivate a move."
Sub-par ? Maybe, maybe not - you seem to be missing the point, which your 'contact' touched on, which is that using bought in IP like ARM gives them a great flexibility to create customs parts that work well for processing a particular type of data, e.g. scaling out the IO (as mentioned), memory hierarchy tweaks (also mentioned), attaching to dedicated hardware (e.g. custom ASICs for pattern matching, high-speed FPGAs) or whatever they want. With that degree of customization available it's entirely possible to match or surpass general purpose CPUs within a particular processing niche (I seem to remember a while back, the fastest 'computer' for one type of highly parallel algorithm was a basically a bucket of dye). Through-put is not the key however - a combination of through-put, flexibility, specifitiy and power-usage probably is a better metric, and the ability to have all this in-house is certainly not to be sniffed at.
Re: What about CalTrain?
Yeah, fairly sure it goes (or went) to Mountain View. I used it quite a bit when I was in Cupertino for a couple of months back in 2000, and I must say I was impressed (although admittedly being a Brit, used to English trains, that doesn't take much). I'd get the bus into Sunnyvale and pop up to San Francisco on the weekend - it was something like $9 for a 24 hour ticket, which worked out fine. Time keeping was good and loads of room on the weekend... great back garden viewing opportunities, some crackers out there. The double-decker carriages were great - all swoops and rivets and made from proper American train metal (you'd know it if you saw it). All in all a very pleasant experience.
Only real issue was explaining this in the office as it necessitated using quite a few unfamiliar words such as walk, bus and train.
@jake Re: Further proof that these things are childish toys.
It's nothing of the sort - if it were, you'd have to brand pretty much every personal electronic device a "childish toy" (although now I think of it.... but, no). Pretty much every mobile OS you can think of has fart apps - iOS, Android, Windows Phone, even Blackberry OS - they have become a sort of Hello World app for them. Yes, of course they're childish, but you really can't use it as proof of anything except perhaps your own bigotry.
You might hate GoogleGlass (you seem to) which is fine, entirely your choice, and you may consider anyone who touches one an idiot - although that seems simple-minded to me but is very much 'on trend' - but one person developing a fart app to test out the SDK really backs up none of that. I mean, did you actually read the article ? ... or even his posting about what he was doing and why ?... and his opinion of the device ? You probably have more in common with him than you think.
IANAL but it would seem to me, aside from the bountiful prior art, that the use of the word 'typically' in the 'Background of the Invention' section 0003 and section 0004 invalidates the basic claim (or rather any innovative part of it). 'Typically' is not exclusive so permits the possibility that existing methods do not require whatever follows (which is true), it seems a bit like the word 'may' in this context - effectively meaning nothing at all.

Re: They should be forced to use
"Tux fanboys should really take the time to install a Windows Domain Controller and learn how much you can do from that, even without adding more sophisticated tool like System Manager or the like."
..or they could just fire-up a LDAP server and do much the same basic admin using a number of freely available front-ends or go to someone like Softerra and get something that admins openLDAP and MS ActiveDirectory (LDAP with bells) as well as Novell eDirectory (yuck), Oracle Internet Directory (double yuck) and Lotus Domino (good grief, still going ?). Not as nicely presented often, true - especially the free ones, and certainly not as powerful, easy to use or relevant in a Windows enterprise - but there's a lot you can do without really knowing anything about what's under the hood.
Not saying you'd necessarily want but it's there if you need it or fancy a look. It tends to get overlooked as smaller networks typically don't need it, and larger networks often just buy in management software for Unix or mixed networks.
Re: They should be forced to use
"When was it proven that Windows is the only enterprise ready OS? "
Around year 2000 when Win2K was released, undisputed till now."
Undisputed by whom ? Citations ?
"Wanna argue ? Don't, because you obviously never tried manage tens of thousands of either Windows or non-Windows desktops.
Must have come as a shock to all those enterprises who ran, or are running, on Solaris, HP-UX or AIX then..... probably news to CERN too (see e.g. Quattor). Many have moved to Windows, or other *nixes, but that can hardly be attributed soley to the extent OS being 'not ready' for the enterprise.
Note - i'm not slating Windows as far as enterprise deployment goes, I am disputing it's the only enterprise ready OS.
"Your comment about the Linux desktop is particularly childish."
Well, it really reflects state where Linux desktop is - in a kindergarten, for last 10 years at least, must be one retarded child. Seriously, why would anyone in the world use it for anything else than running Firefox ?
Quite frankly, one of the best examples of proving the OPs point i've seen ever... genius !
"Whatever it really thinks about Doctor Who, the BBC certainly isn’t keen on 3D."
That's because people aren't watching it - the Beeb often gets slated for wasting money, and rightfully so, but to make snide sounding comments when it actually employs common sense is a bit much.
"The transmission ... is the Corporation’s final 3D broadcast for the time being"
Yeah - I felt a great disturbance in the Force, as if eight or nine voices suddenly cried out in terror, and were suddenly silenced.
Are these the same Dodd Frank regulations from a while ago that were US (non-international) regulations, using certification paperwork based on existing schema that was presented a long time ago as a framework to the SEC, that were non-comprehensive and optional and could be adhered to a posteriori, or have they changed a lot ?
It's not that I disagree with the more centralised checking - far from it, I think it's an excellent idea - but at least one of the previous articles you linked to contained more than a little FUD and i've not looked at the regulatory documents since that time so haven't seen what's the current state of play.

Hum, it'll be interesting to see these elusive little neutrino fellas in a bottle for once.
Yeah - i'm also intrigued by the "28 intergalactic subatomic particles, which were embedded within a cubic kilometre of polar ice"... presumably they just sort of fell out on the floor when the block was opened, and they had to scoop them up into the bottle.. that must have been a tricky lil'job and no mistake (especially if you had gloves on or no nails).

Re: Off the top of my head.
"(Bearing in mind exchange of encrypted data is always vulnerable to the initial key exchange)"
Not normally an issue, although you do have to be a little careful e.g. using a bog-standard public key cryptographic scheme the only obvious vulnerability in the initial exchange is associating the user ID with the public key, and there are ways to easily check that without needing a big PKI set-up.

Yeah - first person for a while that's made Larry Ellison seem vaguely sane....
"The New Zealanders (at least) refer to a tow truck (operative) as a towie, little realising that this actually means The Only Way Is Essex..."

Who'd have guessed ?
"These events led me to the conclusion that, at least in my case, educational techniques and sport were mutually exclusive and that the essentialness of sport to a rounded education was a myth of the same magnitude as any of those in The History of Herodotus."
'Rounded education' is usually (in my experience) intended to imply exposure to many different experiences, all of which contribute to the education process - as in 'round' as a synonym for 'whole' or 'complete'. It has never (again IME) been used to imply that a fully rounded education is essential to attain some type of academic level, or similar achievement.
Given that, you could argue that sport is essential in a rounded education - but only in the sense that it would be incomplete without it. There is, however, much that can be learnt from various sporting endeavours outside of the gross physical and mental skills, some of which i'd consider to be highly educational. Moreover, given your almost complete lack of experience of sport, i'd say you were particularly ill-suited to comment of what insights it may have afforded you. To be honest, I also expected a tad less hubris in this regard from an 'expert witness' - or at the very least, a somewhat more visible appreciation of the limits of their knowledge.
That aside, I found much of the article very interesting indeed.
So to try and summarise... the only bit the airlines and boffins were really concerned with, they still are - but now instead of asking people to turn off the devices completely, they can remain on as long as all the radios (in the general sense) are disabled. Is that right ?
If so, it's somewhat more convenient at times, but would also need slightly more wherewithal from the user to accomplish than now. Some may find that mildly concerning - frankly i've sat next to plenty of people on planes who seem quite far away from the reading age required just to turn the things off.
Ooooo - this sounds like fun.. maybe point two of them at each other (or big bendy magnets to cross the stream from one) and put the detectors where the beams meet. Ta-da ! Alternatively put your target on the end of the really long stick, lash the detectors to it and pop it in the beam (Careful : wear protection on your forearms just in case).
Re: cause headaches in finding open-source builds of current Windows-based scientific applications
'"I didn't know Linux was incapable of running closed source applications."
If you're not joking -it does '
..I was detecting irony (or rather, sarcasm) in the OPs statement - of course that might have been wrong as well. The article was seeming to suggest that the switch from Windows to Linux would necessitate moving from closed source to (presumably different) open source applications - which is not true in the general case.

'"a cloud of virtual particles around them that continually sweep in and out of existence"
Well, it's just a fun way of describing things so that humans get at least get some impression of the mad world of quantum mechanics, isn't it. Particles fizzing in and out of existence isn't that bad a way of thinking about things.'
Absolutely, although they do have consequences which make them more than a mathematical trick - e.g. black hole evaporation. In that sense they are very much real, or at least as real as anything else down there... :)

"Clichés die if you don't overuse them."

@The_idiot Re: And this, for me...
"Whatever messages look like (binaries, non human or machine parse-able blocks of text) - then prior to 'decoding' it, I have to allow my machine to accept otherwise unknown and unintelligible blocks of 'stuff'. Because it must be OK - after all, it's 'just an email'.
Have I just opened up a rather convenient attack vector for the types of people I _don't_ want putting 'stuff' on my machine? Whether virus makers, script kiddies - or even the very people I'm trying to protect my privacy from?"
No - you haven't necessarily opened up an attack vector - your crypt text doesn't need to be executed and neither the encrypted nor decrypted streams need undergo evaluation beyond simple bit operations with no side effects (i.e. typically the input streams are just read into buffers, run through a bit-manipulation engine and re-write to a new output stream). If you don't feel brave, do all that in some well embunkered sandpit to catch execution exceptions etc). You don't need to 'check' it's safe, as you never execute it, the bit manipulations have no side-effects (e.g. the output of one operation is not used as some reference or pointer to further data) - you just run the bytes through the engine and look at the result - in hex if you wish. It will either make sense or it won't.
It might be worth looking up some simple examples of something like public key encryption to see how this actually works in a concrete case - there are plenty out there e.g. this Mozilla introduction gives enough information to start with.
"No matter what secure system someone comes up with, to send an email to one person from another, it will be in clear text."
Errr - no. The message body can be in cipher text or clear text, or even a binary attachment. How the receiver decrypts the message text depends on what what system you're using, who has whose keys etc. All that needs to be in clear text is the recipients email address, obviously.

'"No one ticked the box that says the NSA can read my mail."
Indeed not, but as Google successfully established with Gmail reading is not really "reading" is it? It's just hanging around innocently, whistling.'
Don't be so naive - you honestly think the security forces in the US and elsewhere were waiting for that (ill-considered) judgement before intercepting and/or scanning emails ?
"...we should only consider the interests of the producer insofar as that is important to the consumer.
An extension of this is that we really don't care who produces something but we do care that it is produced."
Surprisingly for me, I was broadly with you up until here. The extension only follows if the consumer is utterly indifferent to the producer - Smith comment does not mandate that. If the end result is functionally equivalent then there may be many reasons to actively choose a particular producer, e.g. an SME over a established multi-national. Indeed some may hope that consideration of the producer, given functional equivalence of the product, is something that might potentially have a beneficial effect to the system - unless one is deliberately trying to achieve some extreme form of free corporate capitalism.
"Or they could just look in the window and see when there's movement or activity, or just see when the car's on the drive and then test by knocking on the door?

Doing it over the network potentially allows you to automatically scan thousands of addresses, or more, then analyse it at your leisure.
"Plus somehow I think even in these modern times the intersection of people with both hacker and burglary skills (and the desire to use them) is probably rather small?"
True - but the same person doesn't have to do both, e.g. a really simple setup would be J.Random Hacker scans the domestic networks, analyses the result, parcels up the most promising candidates by area and flogs them to the local under-world representatives - exclusive rights for those who pay a premium.

"Just out of curiosity, what exactly did Bill Gates [...] say or do to force you to buy or use their products?"
You have an interesting lack of understanding how monopolies work. Microsoft weren't the first, they won't be the last and they certainly won't be the nastiest - doesn't make them angels however. That said, at least Gates, unlike most other of his peers, and the Foundation (although not without its issues) is actually doing something useful with our money.

Re: Im surprised
Indeed - the sample size is still rather small at the moment. That'll improve in time, but currently it's leading to a lot of "how peculiar" comments from the astronomical community... which is one of the reasons why science can be such fun !
"Perhaps more intriguingly, they say that if there had ever been a Kepler-78b in our solar system - and apparently this is quite possible - such a second Earth would have vanished long ago, leaving no trace for us to find today."
Not saying our understanding of the creation of solar systems and their dynamics over billions of years is lacking, obviously, but were it the case that those models and assumptions are a bit off then, conceivably, such a thing might not have vanished completely yet but be, oooooh I don't know... currently about a million miles out from the star. Just a thought... That would mean, however, that we really don't quite have the hang of this system evolution malarky (understandable) - I mean, when was the last time you heard an astrophysicist say "That's odd - didn't expect to see one of those there" eh ?
Ah.. hang on...

"Well, no other device allows huge mailboxes to be instantly searchable."
I presume you intended that to mean locally stored mailboxes using an installed application ? Even then, i'm not sure that that statement is correct.

Re: Usage share
"Not that hard to work out. If you collect web server logs together and analyse them then you find that over 80% of mobile devices that accessed them were Apple iOS machines."
The figures i've seen from the US show iOS mobile website usage between 65-70% - as the US typically shows the absolute peak of iOS usage for stats (60% iOS market share last I looked), i'd guess that would hint at it being a peak worldwide. Stats for Europe and Asia would be different, Africa even more so.
"These are numbers generated by third party analytics firms over a wide range of web sites."
Web sites in which country, in what proportion ?
"The implication here is that a large proportion of Android devices are never used to access the web, which is kind of odd given that's what they are primarily designed to do."
The implication could also be that you're extrapolating too far - difficult to tell without any real information - possibly due to your statistics not being reflective of world-wide numbers. The access number would also need to be for unique devices for the assumption that low usage = no usage (which you seem to be making - correct me if i'm wrong).
