As for those claims that we have a crack team of ex-Ma Bell billing experts working on proposals to better 'monetize' the internet and ensure hilariously usurious returns on 'investment' by incumbent telcos? Well, now, I never disavowed that...
While I can understand why they went with a cheap, standard, connector(rather than yet-another-goddam-slightly-different-barrel-plug), I suspect that the rPI support guys are cursing the day that they chose a USB socket as a DC-in jack.
To put it politely, the quality of USB chargers and powered hub wall warts is excitingly variable. If you are trying to run an ARM SoC, a USB ethernet controller, and possibly a couple of other downstream devices, all with just a +5 rail of potentially erratic specs, that isn't good for reliability. By going with the USB socket, they opened the field to every last dollar-store iCharger knockoff and its creative interpretation of what +5vDC looks like...
The funny thing about florescent tubes is how recently they became 'controversial'. Essentially all the R&D was in place for conventional hot-cathode tubes by the late 30s, and they were owning the commercial, industrial, and other cost-sensitive bulk sectors. And these were the good shit: Mercury, beryllium, the kind of stuff that wasn't good for you even in the '50s, back when smoking and liquid lunches were doctor-approved...
Once they became symbols of tyrannical envirofascist totalitarianism, though, you'd have thought that they'd started filling the things with nerve gas.(Amusingly, the bulk commercial/institutional users still don't give a fuck. Just stay after hours at any giant cube farm or similar and you'll see the janitors shoving around garbage cans full of old tubes, half of them broken, without the slightest concern...)
I will have to give the Note a look. The Wacom RF tech is spooky accurate(and, incidentally, pretty cool looking. An entire multi-layer PCB antenna array, sorry about the shitty scan, crammed in behind the screen.) Trouble always was that the 'Tablet PC's were still basically just laptops with particularly unreliable hinges and the freestanding tablets(in addition to being alarmingly expensive) didn't allow you to write on whatever you were annotating...
In the defense of Britain, that was the subset of the British who were such theocratic wackjobs that they sailed across the Atlantic in a glorified tub and set up shop in a ghastly wilderness hellhole just so that they could enjoy the pleasure of being on the enjoyable side of religious persecution...
There are, or were, some restrictions on air-freight quantities of the things; because they were suspected in a couple of cargo plane crashes(potentially hundreds-thousands of cells on a pallet, all it takes is one to be defective and you get a cascading failure-into-zesty-metal fire...), but I assume that they realized that grabbing everybody's cellphone, mp3 player, laptop, and everything else just wasn't going to fly.
Having observed a few laptop battery packs decide to go out with a bang, I certainly wouldn't want one in my lap; but I'd also be fairly surprised if one could seriously imperil a passenger aircraft. Burn the poor bastard carrying it, definitely. Probably-toxic-smoke, quite likely; but it isn't a grenade or anything, and aircraft cabins are saturated with halogenated flame retardants, which should give the other passengers time to smother anything that appears to be trying to catch fire.
What are the odds they'll let something that can heat up that much on an airplane, once they read this article?:\ More seriously, I assume this is over a very, very small area, and the chip dissipates that heat within a few minutes, and that it would only be warm to the touch for a few moments... but I still gotta ask: Is there the possibility of catastrophic failure? Like if the chip was maliciously reprogrammed to trigger all the heating elements simultaniously?
The actual danger as a burn hazard/ignition source is still limited by the total battery capacity of the device(even assuming that the manufacturer entirely cheaped out on fuses or other protection). A hypothetical attacker could do as much damage, probably more, just by shorting the battery with a length of wire or a paper clip or something...
Given how frequently(and often painfully, toward the end) companies seem to founder in the face of structural changes that they can't do much about(short of essentially re-founding as something else, just carrying over the campus and the capital), I have to wonder if there has been any work done outside of the barbaric corporate raider sector on building companies with clean exit strategies...
After all, there isn't any reason why a company needs to struggle to perpetuate its existence forever(any more than a company would struggle to perpetuate the existence of a given product line forever). Sure, the process that companies who do fight and then die go through is pretty grim; but that is, at least in part, because they keep struggling even after the situation is hopeless, and just bleed and bleed and bleed.
Is there a process where you just quit before you are behind, wind down neatly, rather than the corporate equivalent of spending a few years stuck full of tubes and unresponsive in the ICU?
Polaroid was always a bit of a niche company. They happened to be in a fairly big niche, but they were very unique in what they did. Their monopoly kept them going until the market changed.
Kodak was killed by shortsighted managers who could not understand the implications when they invented digital photography.
[car analogy] Both companies were buggy whip producers. Kodak invented the internal combustion engine, but never thought it would catch on.[/car analogy]
The 'buggy whip' analogy isn't quite fair to Kodak. The techniques required to produce their particular buggy whips involved a fair amount of chemical expertise. That spun off as Eastman Chemical in 1994. They may or may not be setting the world on fire; but nobody is preparing their funeral. This doesn't change the fact that Kodak is still totally fucked, or that they managed to almost entirely fail to capture the future that they invented; but if we had to horribly overload the buggy-whip analogy, it'd be fair to say that Kodak is still trying to sell buggy whips to the consumer transport market, while the market has moved on to BDSM fetishists and the production of diversified specialty leather goods.
Of course I want to remain as anonymous as this post. Why would I be okay with Netflix selling my anonymous viewing details simply because it opens the door for a competing company that will not sell or store viewing habits. Look at DuckDuckGo. That's capitalism. Provide people a service that can or be almost be as comparable, let the people decide which is better.
Who said anything about selling 'anonymized'(to the degree that actually works) viewing histories?
Things have gotten better; but I'd say that we aren't there yet.
E-ink has gotten good enough for light reading of anything that reflows adequately(and cheap enough that there is little risk in giving it a shot); but the refresh rate and available panel sizes and resolutions still make serious PDF crunching rather ugly.
The newer iPads have the resolution and speed to do PDFs justice; but capacitive touchscreens aren't exactly god's gift to stylus-based annotation. Yeah, they sell capacitive styluses; but it isn't exactly a Wacom...
"Traditional" tablet PCs had the Wacom pen input for annotation; but some mixture of technical limitations and PC OEM tastelessness always made them slower, clunkier, and more tethered to their AC adapter than was ever entirely comfortable.
If I had the cash, and really wanted to get away from the 'just-a-decent-laser-printer' solution, I'd strongly consider a portrait-oriented Cintiq display mounted on an ergotron-style floating arm. A Cintiq 22 or 24 is far too heavy to treat like a tablet; but the arm should give it effectively zero weight, and you'll get reasonably high resolution and excellent pen input.
The fundamental misconception of the paper(which, as you note, Apple was first to demonstrate in a broad and serious way) is that DRM is about controlling exfiltration rather than controlling playback.
Yeah, obviously, even the people who design PAL hardware for thermonuclear warheads are going to have a difficult time designing DRM systems that will resist prolonged physical access by a sophisticated attacker. If they have to build such systems on a consumer electronics budget, forget about it.
However the 'break once, play everywhere' DRM defeat model implicitly assumes that computers will be 'default allow' devices. That, unless a given object is specifically encrypted/crippled/otherwise fucked with, they will happily do their best to work with what they are given.
This simply isn't true. Market forces have prevented going 'default deny' in certain highly competitive sectors(eg. nobody selling cheap DVD players can get away with selling DVD players that play only CSS-encrypted disks) and for certain legacy formats(it isn't really an 'mp3 player' if it doesn't play mp3s...); but it is increasingly the case that more sophisticated devices are 'default deny'.
None of today's consoles will boot an unsigned binary, even one otherwise compatible with their environment without modification to the system(sometimes a software crack, some are known only to possess hardware vulnerabilities requiring physical modification). The iDevices of the world will reject any.ipa executable package that isn't DRM-encumbered. You can strip off the "fairplay" all you like; but unless you have a jailbroken device or access to a trusted signing key, you aren't going to be running it... Microsoft's "Windows RT" will be the same thing for Windows style executables.
If anything, what the MS guys demonstrated is that (because of the 'darknet' consideration) 'Trusted Computing' as DRM is doomed to failure and its only real function is trusted computing as control.
and stealing sales from Wintel ultrabooks doesn't really help Microsoft or Intel.
The Surface Pro IS Wintel.
It doesn't directly hurt them(in the sense that WinRT makes Intel sad or iPad sales make them both sad); but it is somewhat troublesome for Microsoft's attempts to build a tablet-experience-that-actually-doesn't-suck.
If I'm a developer, and my prospective customers have the choice of buying ultrabooks for $6-$700ish, some with touchscreens; but all with conventional mouse/keyboard, or $999+ Surface Pro devices, only some of which will have a keyboard, fewer a mouse, I'm not going to be overly excited to go all touch crazy. It'd be cheapest and easiest just to re-hash whatever worked on Windows 7, maybe with some token status app widget for 'metro', and only slightly harder to just bump up the button sizes a touch to deal with touch inputs and call it a day.
The weaker "Surface Pro" is against just plain old laptops, the weaker the case for any serious MS-centric tablet development is(which then leaves WinRT out in the cold, with either a very thin software library or a bunch of really crappy ports).
Does anyone really think that less people will play farmville just because people can't share their progress on facebook? Zynga probably already has their own back-end for players to communicate with each other.
My impression(based on the rate at which they churn out new art variants and other slight tweaks, as well as the high attrition and fairly low real-money-user portion) is that they aren't so much worried about "fewer players", since most players pay nothing; but less new blood. Zynga relies on having a low barrier to entry and continuous 'social' spamming to provide an influx of new players, some modest percentage of which will be retained or monetized. Cut off the flow, and you then just have attrition.
Well, at least snow and ice definitely don't have some of the highest Albedo values among terrestrial surface coverings, so losing them won't increase absorption of solar radiation at all!
I was thinking the same thing! I have a 2005 BMW; there's a button on the mirror which would let me make a call if i had one of those phones or, iirc, a bluetooth module which cost $800... I think all the manufacturers should do is agree on a standard for attaching mounts to the dash, provide bluetooth to the sound system, and have usb power outlets strategically placed. Of course that's not what's going to happen.
We already have ISO 7736. Let's just say that it is treated as more of a series of polite suggestions than as anything actually worth implementing.
Why? most quality servers dont need a floppy for Bios upgrades. maybe some of the off brand crap does, but I havent had to use a floppy for Bios upgrades for well over 4 years now.
The one situation I've run into that required a little improvisation is with BIOS or firmware updates on ESX hosts. The server vendor provided update packages for all the usual Linux and Windows server flavors; but it was bootable media or nothing if ESX was all you had to work with. Thankfully, the management cards could emulate a boot floppy or boot CD if fed a disk image, so I didn't have to soil my hands by actually touching a floppy disk or CD-R.
Yes, a good hammer and a block of wood. Don't hit the device directly, lay the piece of wood across it first. Comes in handy for seating cards sometimes.
If vendor warranties are a concern, you might want to look into the non-marring mallets used in fine finish carpentry and certain other specialty applications. They lack the visceral pleasure of a good 5lb sledge; but they can still deliver some serious fine-adjustment with none of that awkward marring that gets your RMA denied...
What I find curious about a need for temp IT staff is this:
If you are doing a deployment of that size(unless the district is a 1 room schoolhouse or something, "grades 6-12, all students" is a fair number of laptops), you will need some sort of system imaging setup, to plunk your OS and applications on new machines/machines that lost an HDD, you will need a decent number of lowish-skilled screwdriver labor to keep up with all the physical damage and parts replacements, and you will likely need some basic network infrastructure so that OS updates get delivered and user documents aren't languishing on fragile laptop hard drives without some sort of backup to the fileserver.
Now, if you have all that stuff, and you run into a virus that whatever AV software you were running couldn't handle, what's the problem? Break the laptops down into logical groups(by grade, by homeroom, whatever) draft all your hardware fix-it guys, and re-image one group at a time. Annoying? Yes. Catastrophic? Not really.
" wouldn't fit any normal definition of old" - plzzz.... fashion industry anyone?
Oh, AC, that isn't news because it is normal and OK to discard women for getting old and ugly. This is news because it is cutting a brutal swath through old guys who have a Right to be accorded respect as they begin to grow dignified salt-and-pepper hair and a pinstriped suit.

I'm not sure you quite grasped what the GP said. Take the set of integers. A subset of the infinite sequence of integers is [1,2,3,4,5]. Now, is that subset repeated an infinite number of times in the infinite sequence of all integers?
Also, that's the combination for my luggage.
In the case of the set of integers, my understanding is that no subset of the set of integers is a member of the set of integers, much less repeated(since the set of integers contains no sets, only integers, and even singletons whose sole element is an integer are still sets, not integers.).
The 'immortality' of these cells is disputable: once the host is dead and, say, cremated it's "game over" for the immortal cells just as well as the host ; )
Most scanners of this size don't really have a 'sheetfeed' mechanism(though there likely isn't anything stopping a clever opponent from sneaking a few percent of the sheets out more or less intact.
Small shredders have a more-or-less-printer-like 'paper path' because they suck and can only handle a couple dozen sheets of paper and maybe a CD or credit card at a time.
Larger shredders are less picky about the feed rate.(No connection to SSI, I just have to enjoy a company that operates under the motto of "What needs shredding?")
