What's the point of more mobile bandwidth...
... if it costs you at least 10x more than non-mobile data. Most of the stuff I want to do out & about gets done by finding WiFi hotspots first where possible, as I'd rather not blow my month's allowance in a couple of hours.
Maybe Ofcom should have some pointed words with the networks before letting 'em anywhere near new spectrum.
Hi pot, kettle calling...
Of course, Microsoft have never done anything dodgy that folks might want to whinge about on a mug, t-shirt, water bottle etc. Bah, a pox on all their houses...
Could get fun if somebody goes for the retaliation, think I'll give my popcorn supplier a heads-up.
Re: Been there, done that
Yup, me too, no big deal. As you say, the biggest headache is the dynamic IP address, or more accurately how it's treated by other mail servers. Hanging on to my static IP address partly for that reason and also 'cos I run DNS for a couple of domains.
Re: Regardless of the merits of the Apple patent
I think it just means that if you have a good idea, make sure you've got the patent application well and truly lodged *before* you show it off to world + dog; presumably if you don't you're considered to have made it public domain. Just guessing, though.
No idea how you managed to get downvoted just for asking the question, btw.
Re: Wonder what they've broken this time
Right with you there. If I'm running "community" versions of a distro, I kind of expect to hit problems during upgrades and am pleasantly surprised when I don't get any. For critical servers, I'll run a commercial version and make damn sure I've checked the compatibility matrix before I start, although some vendors habit of changing chipsets without changing their model/type numbers can still catch you out. Mind you, given the budget I'll still put in IBM Power servers and AIX, damn near bulletproof upgrades across generations of servers and a piece of piss to admin...

Re: Error in LTO6 capacity
Yup. The article suggests Oracle are positioning this against the IBM TS1140; a 3592 JC cartridge is 4TB native, but the LTO6 cartridges are indeed 2.5TB
Trading arms race...
So, the race is to get your better / faster system trading before the other guys beat you to it. So how long (even if it's not already the case) before the test regimes get pared back so far that a cockup is almost inevitable? After all, when did 'if I test for this, it might avoid a catastrophe' ever trump 'if you put this out now instead of next week, I'll make a shitload of dosh'?
Re: Neat idea BUT
Agreed, the IP6 gateway (DODAG root) is a SPoF. But then it's a logical entity; presumably all the usual tricks apply to make the platform as robust as possible physically (redundant hardware, diverse path etc), but then we all know that guys with big yellow diggers and back hoes are ingenious when it comes to cutting off buildings.
A *very* quick scan (I have a short attention span) of the RFC suggests that the DODAGID is based on the IP6 address of the root, so maybe the root node can be changed by just moving the address to a different location? I'm no expert, so that could be complete bollocks of course. Hopefully somebody with curiosity and more expertise can comment.
Re: Inward pointing spikes..
"So it's liquid under the icy crust"
Umm, if I've read it properly, then exactly not. Rather the supposition is that it's bloody great big chunks of ice (the roots) being held down by a seriously thick & rigid ice crust - rather than rising as would usually be the case. That leads to the lower density, thence to the gravitic anomaly; although personally, I think there's just a sodding great ice cave with a monolith in it causing the blip.
"This web site works only with HTTP 2.0. Please upgrade your browser."
Whoa there, calm down. You do realise that HTTP is only the delivery mechanism? Most web site developers never go anywhere near HTTP, in fact I'd be surprised if many of them even realise it exists. So, how will this play out?
First up, the likes of Apache et al will start including HTTP 2 support in their web servers. Mozilla etc. will start building libraries for it in their browsers. And guess what, there will be a negotiation as part of the initial handshake between client and server as to who supports what, just like there is now for things like HTTP 1.0 / HTTP 1.1 support, compressed data and so on. So, faced with a client only supporting HTTP 1, the server will simply deliver over that, but would take advantage of HTTP 2 if it were present. This approach is far from unique to HTTP, of course
By the time it gets to the point where a connection fails due to lack of support, it'll likely be for one of two basic reasons; 1) you're using a truly ancient browser / library, or 2) some fuckwit admin has managed to configure his server to only use HTTP 2 before the majority of the world can support it. Either case is easily remedied with a length of 4 x 2 with six-inch nails knocked through it
Re: Increased energy density leads to increased risk
"...on par with a hand grenade as it is"
Exactly my thought when going through Heathrow security recently with a colleague who was carrying a USB powerpack (i.e. big battery with USB connectors) in his kit. I was sure he'd get stopped, and he was - although not 'cos of the pack, as it turns out.
Checking the present regs, you can actually carry on batteries up to 100Wh. My colleague's pack was about 40Wh, and comfortably hand sized. Strikes me you can take quite a lot of energy in a small space; I'd be more bothered about these letting loose in the overhead lockers. Don't know if there's any sort of knock-on possible, but I think I'll be keeping my devices as separate as possible in-flight.
Re: TN Screen? That's not at all premium..
Curiously, Sony's online documents don't seem to state anything beyond the fact it's a TFT, despite providing mind-numbing levels of trivia on just about everything else (http://www-support-downloads.sonymobile.com/sgp311/whitepaper_EN_sgp311_sgp312_1.pdf). To an old cynic like me, that suggests it probably is a TN 'cos otherwise the marketing droids would be yelling it from the rooftops, rather than appearing to be slightly embarrassed about it.
That said, I'd have a look at it first. TN doesn't automatically mean crap - who cares what the technology is if it's actually good enough for how you actually use it? If I expected to have lots of folks trying to see the screen at the same time, or was constantly looking at it off-axis then yes I'd probably want an IPS-type panel. But most of the time? Not a lot in it...
Yup, from the bank account here too. Better still, it actually works; we claimed to replace my son's phone (Galaxy Note), no problem, brand new replacement. Mind you, he had fallen thirty-odd feet into a shallow river with a rocky bed, spent about 90 minutes in the water before being airlifted to hospital and another two weeks stabilising two crushed vertebrae and a cracked pelvis, so the insurance company couldn't really argue that it wasn't accidental damage...
Or rather this is what happens when you (or rather the bean counters) think you can safely outsource your data centre to a bunch (and I don't just mean FH here) whose strategy seems to be to say 'Look at us, we're really big, isn't all this stuff impressive,much bigger than you'd ever have so it must be much better. Oh, and have you seen how cheap it is? Think how much money you'd save. No, really cheap. Ever so cheap. You'd be a mug not to want to save this much money. Of course it's safe, how could it not be? And it's really cheap.'
So you outsource, things go titsup, and guess what? Instead of being able to escalate (to a single director if it gets bad), re-prioritise your recovery and so forth, you're now just one voice amongst lots, all clamouring to get those critical systems back on line, and you're probably nowhere near the biggest customer so how much influence do you really think you've got?
Economies of scale (for the provider) exist mainly when everything's going smoothly. Scaling your recovery so that you can get away with fewer bods requires investment in tools, techniques, developing robust procedures, testing... all those things, in fact, that cost. When the market's in its usual race to the bottom pricing mode, guess where the corners get cut (clue; it's not the director's bonuses). So, for those screaming at FH for not being perfect, I'd have to ask: what planning did you put in to make sure that when a big outage in your (now outsourced) data centre happens, your business didn't take a disproportionate hit? Or did you actually believe the salesman when he/she trotted out the usual soothing words? And how were the unicorns?
I'm not against outsourcing per se, despite the impression you might have got from the above. I'm against the school of thought that seems to believe that because you've outsourced, you can abdicate all responsibility as well. It's your business, not theirs.
Re: "the world's first commercially available 5GHz CPU,"
Actually, bunging a full POWER chip in to a desktop wouldn't be difficult - remember IBM will cheerfully sell you POWER blades, so that's roughly ATX sized. The footprint's similar to Intel chippery - in other words most of the space has to be given over to heatsinks. They're still air-cooled, but it's fair to say the fan noise wouldn't be living-room friendly...
Petabytes in minutes?
> '...allow petabytes of data to be backed up in "minutes, not hours".'
Oh, dear, who fired up the marketing hyperbole machine? Petabytes, only if you've got a *shedload* of interfaces. And presumably are backing up to the bit bucket.
By coincidence I've just done the sums for backing up 125TB in 8 hours; a tad over 32Gb/s sustained. So, assuming I could sustain 16Gb/s and I'm backing up 2 petabytes (their plural, so it's got to be at least 2!), play fast 'n loose with decimal/binary PBs to keep the sums simple and that's what, 32 ports give or take a couple?

> "Why somebody would want such large bandwidth is beyond my understanding"...
Actually, despite more years in the industry than I really care to admit, I still find myself asking the same question, and it inevitably turns out that something appears to provide the answer "ah, that's why". LAN to the desktop? Why? 10Mb switched to the desktop? Why? 100Mb... you get the picture.
It seems to be a genuine case of if you build it, they will come. I still recall when putting video conferencing on the general (not dedicated) company LAN was considered A Big Thing, now it's pretty much taken for granted even on mobile.Yes, techniques have improved, but it's mainly the higher bandwidth at cheaper cost that drives these things. So big bandwidth - bring it on!
Re: Activist Shareholders
Agreed. Although sometimes you need shareholders to stand up and hold a board to account, if the board's not acting in the best interests of the company and its longevity. Except that's the kind of shareholders that are a) knowledgeable and b) interested in a *fair* return on their investment over a period, not a maximum return in as short a period as possible.
An awful lot of 'investors' seem to have forgotten that the idea is to help a company survive and grow, to mutual benefit, rather than to trouser as much as possible then move on just before the train wreck to the next opportunity.
Re: "...It's just you really have to work at it."
Right, here's my bit of tin-foil hattery:
So, Linux desktops have never really taken off 'cos it's so difficult to get it to be 'nice', like the Microsoft Windows environment (other excuses may be available). So, Microsoft, in a far-sighted attempt to avoid accusations of anti-competitive niceness, decide to level the playing field by producing a system that you have to put effort in to if you want to avoid those pesky WTF moments. But if I've got to do that, then...
What we have here, people, is simply MS's way of trying to persuade the great unwashed that there might just be another way. Which will, naturally, lead to increased competition in the marketplace, to the betterment of mankind and happiness all around. So in fact Microsoft's introduction of a bit of a dog's breakfast of an OS is simply an altruistic attempt to make us all happier.
Yup, reckon that's it!

Re: Deliberately misleading nonsense.
"... you get through to a Yorkshire call centre"
Yes, granted, but it doesn't mean your problem actually gets fixed. As it happens I have both VM and PlusNet (work reasons, also the static IP from PN). The one and only time I had a real problem with PN - total disconnection - it took them the thick end of six days to work out they'd cocked up a configuration. Oh, and they actually closed the original call I made after two days, something I only found out two days after that when I called to find out why I hadn't heard anything.
Bit of a shame really, 'cos otherwise I've been pleased with PN for years (since before they got borg'd by BT), it's just when it really mattered they screwed up. At least you *expect* VM to be a bunch of chocolate teapots, although I have to say the actual engineers that get sent out have been pretty damn good.
One can only hope that your doctorate was subject to better proof reading than your post! It may have been a literary nothing, but presumably you worked out where the exit was eventually?
Muphry is real...
Re: Wife acceptable
That answers a question I was going ask - the OBi110 with RasPBX. I have a, errmm, window of opportunity to muck around with this (couple of knackered DECT phones in the house). 35 quid for the OBi rather than 56 for the Cisco (on amazon at least) makes it easier to put the cost case to the CFO (wife...). Have an upvote, squire.
Re: Very good indeed
Yup, real-life case beats uninformed opinion every time. But am I the only one that interpreted this mainly as the engineers benefitting from getting decent kit, rather than getting W8 as such? If developers are taking the opportunity to put better and more relevant/functional frontends on their applications (mobile or otherwise), does the underlying OS actually matter these days? Just asking...
Re: Glass platter
For 'glass' don't think in terms of the stuff that's held up by your window frames. Can't give you the physics / chemistry behind it, but glass is a state rather than a specific substance per se. I would imagine it's pretty damn robust, whatever they're using.

IIRC, there was a recognised problem with the HDMI config in some combinations. Especially cheapo Chinese TVs... Can't say I've seen a problem with feeding my BenQ monitor. Once I remembered to plug the other end of the HDMI cable in, that is :-)
Re: The vi thing
@Pirate Dave "so was EDLIN on MSDOS boxes..."
Yup, and eventually it got supplemented with EDIT, a full-screen editor as opposed to the line-mode EDLIN. Equally, vi is a full-screen character mode interface for ex, the line editor that came before it, which helps to explain some of the more err, quirky, corners of vi. So your reference isn't quite on the mark - har har, have at ye, matey!
Bear in mind these editors appeared before the world of GUIs, and in some cases before terminals with cursor keys, and some things make more sense. Doesn't make them obsolete, necessarily; surely one of the lessons we learn as *nix admins is you use whatever tool does the job best for you. Nano, Pico, Kate etc. are excellent tools, but give me an AIX image that I've had to take to a minimal maintenance shell 'cos some daft bugger's fubar'd the OS without a backup, and I'm bloody glad I can navigate vi!
The vi thing
I know vi isn't the most instantly intuitive tool out there, not surprising given its heritage. I think the thing that throws most folks inititally is the separate insert and command modes.
I usually make the point that it's the one editor you're likely guaranteed to have available to you. So it pays to spend a few minutes working out a bare minimum of commands (insert, delete, save, exit without save). And if you stick with it, the vi command set is remarkably powerful, more so if you get the hang of regular expressions.
Re: My PI
@Annihilator - dead right. eBay for the adventurous, CPC / Farnell etc. for slightly more reputable, even Amazon Basics.
Do a bit of homework and you'll generally find that for short cables, there's little or no difference between cheap and expensive cables. Go long distance at v. high resolutions and you *might* get some issues, data rate definitely falls with distance. That said, I can happily play full HD over a 5m cable that I paid less than a tenner for.
for the EU. Normally you have to really dig in to the fine print to work out what the scam is. This time they're outright asking to create a money trough to get some snouts into.
I'm never quite sure where I stand on the EU, it's got good bits and bad bits like everything else. Stuff like this doesn't, in my opinion anyway, help to enhance its reputation.

Err, the idea of this is to get coverage, not performance per se. Miles would be good. And you wouldn't be using it for time-critical applications (like road trains), so if there's no white space, no problem.

Digital literacy - yes, please...
Where digital literacy is defined as rather more than being able to make a post of facebook from your phone. A basic understanding of how things hang together, why some queries work better against a database than others, that kind of thing. Enough, in fact, to understand the potential impact of your actions. Not in detail, but enough to think twice maybe.
And as for mid-level bods. I'd agree that outsourcing does tend to kill the progression from basic skills through deeper understanding to serious skills. The outfit I work for has been offshoring (even worse than in-country outsourcing) the support teams. It's pretty apparent as people have left that the skills gaps aren't getting filled - there's not the interchange between teams or the ad-hoc grouping of bods to fix issues, so no skills transfer. And yes, the offshoring is primarily about money, not extended hours support. You can tell, 'cause the offshore workforce gets expanded whenever an in-country head leaves...
If you've got yours on order with RS, cancel it and order from Farnell (element14). Or order it from Farnell then cancel RS when it arrives. Lots of folk have been reporting huge delays from RS, whereas some people have even reported next-day delivery from Farnell. Something going on there, not sure exactly what. Oh, and yes, my did come from Farnell and no, I don't have anything to do with them apart from being a customer...

Power to the rocket motor heater thermofoil

Re: No Nexus 10...
I struggle to understand why there's so much antipathy to a stylus these days.

Watching my 17-year old subconciously switching between stylus and finger operation on his Note convinces me it's not a clunky way to work...
