Existing devices, like the Lumia 830 on which this review is being typed, can connect wirelessly to full-size displays, but only with display mirroring, limiting the screen resolution. True Continuum displays different content on each screen. Therefore the forthcoming HD-500 Display Dock requires a Lumia 950 or 950XL.Despite this limitation, there are features in this build that seem to be aimed at Continuum users. After connecting to an external display, there is an Advanced setting appears that only offers “Mirror what’s on my device”, but which would presumably have further options on new hardware.
You can also reduce the size of the text and other on-screen items, making it almost unreadable on the phone itself, but more usable on the connected display. This makes it feasible to type a document in Word Mobile, though I cannot pretend it is a great experience. Connecting a Bluetooth mouse is no-go for me; the mouse works, but types random repeating characters as a side-effect. Without a mouse, it is fiddly to perform operations like taking a screenshot, inserting it into the document, and cropping it. I found myself looking forward to finishing the document on a real PC.
Another issue is power management. In full Windows 10, you can vary how quickly the screen goes off after inactivity, according to whether the device is on battery or external power. This is not possible in the current build, and screen time-outs are particularly annoying since the wireless display disconnects.
Real Continuum will be a better experience, though no doubt there will still be annoyances. The open question here is how useful it will be. It only makes sense if you are travelling without a laptop or tablet, and to use it you will need keyboard, mouse and a display with either the Microsoft dock or wireless connectivity. It is unlikely to replace a PC since x86 applications will not run. It all sounds rather niche.How is Windows 10 Mobile shaping up as a smartphone OS? It is usable though there is still occasional jerkiness on the Lumia 830 used for this review. There are several things to like. App navigation is excellent, with the Start menu available by swiping in from the right, and pinned tiles which support groups as well as multiple sizes. Cortana, Microsoft’s digital assistant, makes more sense on a phone than on a PC, and works rather well, with decent voice recognition as well as handy features like reading incoming texts and accepting dictated replies, now fixed to be always on (as an option) rather than restricted to Bluetoooth audio. Give Cortana a sum to do, and a calculator appears embedded in the reply, another neat feature.
Police have seized the laptop of a BBC journalist who had interviewed men identifying themselves with jihadist organisation Islamic State in order to access these communications.The laptop of Secunder Kermani was taken by police under powers available through the Terrorism Act 2000, according to the Independent.The Register understands Kermani has not been detained or questioned.Kermani, a journalist with BBC’s flagship current affairs programme Newsnight, had produced interviews and features on British-born terrorists and others from Western backgrounds sympathetic to jihadist organisation Islamic State.While the seizure was ostensibly to acquire the journalist’s communications with one such source, it is notable because it forced Kermani to hand over his personal property, rather than a standard request to an internet service provider to collect retained communications data.According to a BBC spokesperson: "Police obtained an order under the Terrorism Act requiring the BBC to hand over communication between a Newsnight journalist and a man in Syria who had publicly identified himself as an IS member. The man had featured in Newsnight reports and was not a confidential source."

While controversy persists regarding police powers under RIPA (Regulation of Investigatory Powers Act) to target the communications of journalists, previous complaints triggered reforms that now require the police to obtain a court-issued warrant before targeting journalists‘ communications. However, the Interception of Communication Commissioner’s Office (IOCCO) reported this year that many police forces were failing to do so.That Kermani’s physical machine was seized by the police suggests that communications between himself and his sources were unavailable to the police through RIPA. Such unavailability has been a gripe of the British government in recent months, with suggestions of banning end-to-end encrypted communications – but not encryption wholesale – left open by Baroness Shields, ironically the minister for internet safety and security, in the coming Investigatory Powers Bill.Michelle Stanistreet, secretary of the National Union of Journalists, said: "There are serious questions to be answered about why the order obtained by the police warranted the seizing of a journalist’s laptop – which may well have contained confidential information on other sources and other stories too. Terrorism laws should not be used as convenient cloaks to sidestep measures that protect press freedom and the ability of journalists to inform the public and to hold power to account."
If Kermani’s communications were encrypted on his device, he may now face a compulsory disclosure order under Section 49 of RIPA which would compel him to disclose the cryptographic key protecting his communications or face a maximum of two years in prison.Ian Katz, editor of Newsnight, said: "While we would not seek to obstruct any police investigation we are concerned that the use of the Terrorism Act to obtain communication between journalists and sources will make it very difficult for reporters to cover this issue of critical public interest." The cloud is a fabulous concept. If you want to try something out, or prototype your latest idea, or give yourself a relatively inexpensive disaster recovery setup, get in there and run up a cloud-based installation.There’s something that the cloud lacks, though: it’s just not fun or cool. Lists of virtual machines in the Azure management GUI aren’t sexy. Neither is the pop-up on AWS that tells you the settings you need to paste into your router to get your VPN up and running. And incidentally, Microsoft and Amazon, I’m not having a pop specifically at you – they’re just random examples that apply to the cloud in general rather to than any one supplier in particular.
One of the things that has to stay in your data centre, assuming you have one, is the infrastructure that runs it. There’s nothing quite as impressive as a spankingly tidy cabinet, every cable run perfectly along the cable management tray, perhaps colour-coded for important connections.I’ve had managers and auditors become wide-eyed and gasp when I’ve opened the cabinet door on a particularly sexy collection of flashing lights and cables (not, I hasten to add, my own cabling handiwork – happily I used to have a colleague called Chris who was amazing at that stuff).And if your hardware vendor does cool kit, that’s a bonus. My favourite was 3PAR’s (now HP’s) funky racks with yellow flashes across the doors. A colleague once referred to the yellow rack and the humming of the disks therein as “a box of angry bees”. What I do know is that everyone commented on it.Sadly, of course, the best any vendor can hope to achieve is second best, because the best-looking piece of kit ever devised has been out of production for years.
Someone told me only this week of her experience rather a lot of years ago when she was a trainee accountant at the UK Atomic Energy Authority … and she went to see the Cray in its data centre. If you think anything can beat a proper Cray (the Cray-1, not one of those poncey 19-inch-rack-with-funky-doors ones they do these days), you’re welcome to submit challenges in the Comments section of this page.
I come from a world of running resilient global infrastructures. This tends to mean a global network connected to a bunch of kit at each location that largely follows a standard architecture, since if everything’s the same it’s a breeze to manage. So you have the same firewalls, same family of switches, the same remote management servers, the same fileservers, the same storage devices, and so on at each site; the only thing that will usually change was the number of switches in the stack, reflecting the fact that some offices are bigger and have more users than others. And of course the only real way to test the resilience of your kit is to have a real setup to play with.

Doing it for real has two key advantages. First, you’re proving conclusively that it does what you expect. Yes, you can emulate a link failure by downing the port on (say) the WAN router, but it’s still electrically connected in some cases. I’ve seen instances where downing the port didn’t cause the link to go down entirely, but pulling the cable did – handy to know when you’re testing your failover design.
Second, though, is when you’re trying to sell the idea of the CFO, or the company’s investment committee, so they’ll give you the money to actually do it.Take a bunch of senior managers to the data centre, open up the rack on your test network, run up a funky streamed music video on your laptop, and invite them to do their worst. “Pick a switch and pull the power on it,” you can tell them, and the video keeps on humming.Stuff the power back in and watch the monitoring alerts all turn green when the switch is back on line. Invite them to pull the cable from the primary (simulated) WAN connection in the knowledge that it’s supposed to be resilient; see the video pause for a few seconds while BGP re-converges and then pick up where it left off without you doing anything.
If you’re a techie, you think this is cool and you feel smug; if you’re a manager you think the techie is some kind of wizard who does weird magic because until this point they thought this whole resilient technology was unfounded bollocks that you made up.Of course you could have demonstrated this from a distance by electronically downing ports, but being there in person and seeing it for real is worth a thousand semi-artificial demos.
In these days of cloud computing, auditors can be a royal pain in the arse. Particularly the younger ones who are sent to do the initial on-site interviews and whose sole contribution to the process is the ability to write down what they’re told.I love taking auditors to data centres. They’re so used to people saying: “Oh, that’s in the cloud” or “It’s in our service provider’s premises … here’s a photocopy of their ISO27001 certificate” that they spend their lives with a suspicious look on their face.
So it’s great when they ask: “Can you tell me where XXX is stored?” You email the data centre receptionist surreptitiously to tell him to be particularly pedantic about ID, then shepherd the auditors outside, hop in the car, drive down to the data centre, go through the (now overly onerous) entry procedure, open the door of cabinet C23, point to the third disk shelf down, and say: “It’s on there.” Even better, you nod to cabinet D14 and mention: “Oh, it’s in there as well, and I won’t bother showing you the other data centre as it’s a long way away, but it’s there too.”Beancounters like boxes you can point at, particularly when they have big black-and-white labels saying “CORP-MailServer-01”. Auditor-baiting is a great game, and you can only do it if you have core stuff in your DC.
You may, of course, end up deciding to move your entire production application world into the cloud. It’s inexpensive, security isn’t regarded as an excessive problem, and support costs generally go down markedly when someone else has to look after the hardware and the software upgrades.Even if you do, though, the data centre remains the ideal place to do your architecture tests and prototyping – trying things out and seeing how they behave. The example I gave earlier about inviting people to pull the connection out of the simulated WAN link is exactly what I’m talking about: a platform that physically exists but isn’t part of the production infrastructure. It’s got routers, servers, switches, storage, bits of cable, its own internet connection, and preferably additional tools such as a WAN emulator, dedicated PC for network monitoring, and so on.
