Trousers down for six of the best affordable Androids

The LTE version isn't a Mk II

It's a variant of the original Moto G - with the addition of SD card support - and, to my mind, better for having a slightly smaller form factor than the new one.

Amazon’s Christmas queuing bonanza!

Warm Braw

OK, but...

All the "collect from" options seem to be more expensive than having the items delivered to your front door.

But if you don't answer your front door (or the delivery agent can't actually be bothered to come that far), you actually get the option to collect the parcel (though perhaps not from such a convenient location) at no extra charge, although someone has had to make a futile two-way journey at some expense.

Meanwhile, the Royal Mail has squillions of empty square feet of space, mostly next to railway stations, which are no longer required for its (relatively) low-volume letter business which could potentially serve as locker/collection sites.

Has anyone actually considered the economics of the delivery business as a whole, or do they just keep trying to optimise separate elements of it that turn out in fact to be highly inter-dependent?

Businessman takes Google to High Court to block online abuse from search results

Warm Braw

Streisand effect is presumably what he wants

In the case of Babs, she was trying to suppress factual information and this drew attention to the information she wanted hidden. In this case, it's presumably to Mr Hegglin's advantage for it to be widely known that the information he complains about is not true - it can hardly make things worse for him, by the sound of it.

Secondly, it sounds that these untruths are becoming a meme as a result of self-reinforcement: if you search for his name, you are presented with information that tends to confirm any pre-existing conspiracy theory you might have.

By republishing the information, even as excerpts - and that, in essence is what search engines do - and then directing readers to the full text, they undoubtedly play a role, albeit unwittingly, in propagating these falsehoods.

Were I Mr. Hegglin, I'd want Google to do as much as they reasonably could to dampen the positive feedback loop, because I'd otherwise have to spend a lifetime playing whack-a-troll.

The argument that "it's the internet" and therefore not bound by laws, taxes, or anything that might make life difficult for freewheeling multinational corporations is wearing a bit thin.

Re: +1 for John Lewis Customer Service

Not having quite such a positive time here. I have a Freeview HD telly that's seemingly had trouble keeping up with the various "coding efficiencies" that have been added to the stat mux over time. It seems to the JL repair agent (and to me) that the manufacturer hasn't (and won't) update the firmware accordingly. Nonetheless, they're proposing to replace the main board (which appears to run at around £250 ex VAT for a new one [rather than a system pull] and which will require about an hour's labour to install) despite the fact they're pretty sure it won't make any difference. The ex VAT price of a better replacement TV is less than that... I think JL has to review the repair before it's committed - hopefully common sense will prevail.

Bloated, slow and self-perpetuating: Cisco slams standards groups

Warm Braw

What goes around...

I seem to remember a time when cisco was saying exactly the same thing about ITU/CCITT standards while being remarkably keen on the IETF where, simply by showing up in sufficient strength, it was able to steamroller the WGs withquickly establish consensus on such abominations wonderfully-elegantly crafted standards as SIP.

I think the problem is that cisco is now bloated and slow and finding that self-perpetuating is going to be a struggle as the various SDOs now contain a greater preponderance of representatives whose jobs no longer depend on cisco.

OMG, that CLOUD has a TV in it! Sony goes Over The Top in telly wars

Warm Braw

Why?

I realise Sony is a content provider and might want to use its consumer products to push its content, but if it only pushes Sony content no one will watch and if it pushes content from other suppliers it's competing with TV and Tablets, which seems like a hopeless battle to fight. If they're hoping for "ownership of the customer", cable and satellite providers have that pretty much sewn up by now.

And as for "TV is about to become extraordinary", that sounds as lame as the promise in my nearest mall that an "exciting" new shop is about to open - as soon as the prepack administrators can negotiate a lower rent for a new incarnation of the same business that traded there previously.

But, given the state of the company, I suppose anything Sony has to lose is already lost...

I suppose it was inevitable...

Now that paper travel tickets are in terminal decline on the tube network, I guess it was only a matter of time before the dank network of crumbling tunnels* that served as a second-user marketplace for them would succumb to redevelopment. But I'm just not sure I'm ready for the next generation of Hoxton Hipsters flaunting their peninsularity.

On the bright side, though, I suppose, over the years, the rebars will have been sufficiently corroded by urine that the new tube entrance will practically build itself.

Microsoft: It's TIME at LAST. Yes - .NET is going OPEN and X-PLATFORM

Warm Braw

Harder than it looks...

While this is extremely good news - .NET is a very well thought out development platform - releasing the "entire .NET stack" isn't quite the ultimate step to portability it might appear. Big chunks of .NET are wrappers around the Windows API, which is largely why Mono is "mostly" complete rather than a complete drop-in replacement.

Nevertheless, it's nice to see .NET getting some attention again after Microsoft appeared to be losing interest.

The police act as agents provocateurs to stack up the evidence against people with views that are considered unacceptable - ie any political views that are not supportive of the status quo - and the courts happily convict them.

Warm Braw

Re: And if I understand it correctly

The judicial system in Italy is overtly political and can be played endlessly by the rich and well connected. Hence, the Italians don't really believe in it.

The judicial system in Britain is covertly political. The occasional expendable member of the establishment fringe (Chris Huhne or Andy Coulson, for example) will be tossed into the fire to distract attention from the all the convictions for being Irish/Black/Muslim or from the harrassment of those having inconveniently accurate views on things like climate change. Unfortunately, the British seem to believe this is somehow better, despite the net result being essentially the same.

UK Cabinet Office's £200m IT bonanza: I got 999 contracts but a pitch ain't won (yet)

Warm Braw

Public sector contracts...

I once had an IT contract with a local authority that required that I should not bring earth-moving equipment onto the works site until permission had been granted (once of the many clauses they'd retained when they cut-and-pasted from a road-building contract). Of course, no-one had the authority to modify the contract so that it was more appropriate to the services being provided. I think, technically, I was obliged to wear a hard hat whenever I had a meeting with them.

I'm sure the nice people at the Cabinet Office have all that sort of nonsense cracked. Though I'd suggest a clause requiring bio-hazard suits if you ever have to meet them on their home turf...

Google Calendar jumps into Inbox/Gmail era

Warm Braw

Who are these apps designed for?

There must be a tiny number of people who are flying so frequently that these kind of features are of potential use and an even smaller number who could do something useful if they find out en route to the airport that their flight is delayed. I can't help feeling that the inhabitants of the Valley are building these things simply to gloat about their unenviable lifestyles.

I'm getting really tired of the tunnel vision of the data aggregators. I run several mail apps because I want my different mail accounts kept separate, not all stuffed into one inbox (may be more convenient for data slurping but it's not convenient for me). I like my calendar to behave predictably, like a diary.

I'm not some robot whose movements are entirely dictated by the instructions coming to me via email (and, bleagh, "social media"), but that's increasingly how we're apparently viewed by the purveyors of "free".

BBC clamps down on illicit iPlayer watchers

Warm Braw

Re: Smart TVs too

The Beeb ended support for the "Bigscreen" Iplayer that was used in a number of consumer media products (including a number of Sony Bluray players) in September, citing a low usage and the fact that the product was 5 years old. However, the Sony models affected are from 2010 and 2011, so buyers would have had access to the advertised-on-the-box feature for perhaps only 3 years or less.

The BBC keeps saying it doesn't have the engineering resources to support all these different devices (that doesn't stop it launching services on these devices and then abandoning them), but steadfastly refuses to produce a stable API that would allow connected device manufacturers (and everyone else) to build and maintain their own clients at their own expense.

But, the general advice to everyone buying "smart" anything is to get a throwaway separate box - anything built-in will be useless long before the device into which it's built stops working.

Warm Braw

Re: illicit viewers?

Indeed. I can't really see the BBC being able to argue in court that the licence to view the materials online extends only to BBC-approved clients.

And of course, it would be possible to replicate much of the functionality of get_iplayer by screenscraping the programme catalogue from the iPlayer website. At least get_iplayer played nice and cached the information for 24 hours - I suspect the author of the next hack to come along won't bother.

And, incidentally, it appears Nitro will have an API key (like Google Maps), so anticipate that as soon as anyone comes up with a useful app their key will immediately be revoked.

Back to vdr it is, then... They haven't yet worked out how to prevent us capturing the off-air signal, but I'm sure some "creative" is working on the idea at this moment...

Hungary's internet tax cannot be allowed to set a precedent, says EC

Warm Braw

The tax is merely a side issue

The real problem is the "limit media and internet freedom" bit. Hungary has been becoming substantially more authoritarian and came dangerously close to having its EU voting rights removed because of constitutional changes that appeared to be in conflict with human rights principles. They've backtracked a bit since then, but there's clearly a political appetite for more central control over all forms of expression.

Amazing how nobody believes it's "their" responsibilty. Always the guy above in the chain - the manager, the director, the shareholder. Particularly if it's a business sector in which they personally participate.

"Are you sure that you want to use this USB Storage device"

You can disable automatic device driver installation in Windows. If you have group policies available, you can disable the automatic configuration of devices in certain classes and with certain device ids.

However, if something mimics, say, a keyboard, mouse, or other common peripheral these options will be of limited use, particularly since you don't necessarily have any guarantee of the order in which the USB devices will be enumerated when the machine is turned on.

Re: Why don't OFCOM handle this?

>Next in the loop

I think the issue of multiple porting has been answered. However, you might not be aware (I certainly wasn't) that while OFCOM require voice calls to follow a ported number, the same does not appear to be true of texts. I got bitten by this some time ago by a number ported from O2 to T-Mobile - incoming texts from some networks were redirected successfully, but not from all. I had to get to a fairly high level in the technical support hierachy before anyone knew that a problem existed and helpfully told me it wouldn't be solved because it wasn't an OFCOM requirement and that the arrangements for exchanging text messages between the mobile operators were "a bit of a mess"...

Warm Braw

Why don't OFCOM handle this?

Well, not OFCOM, they're just the regulator, but some OFCOM-approved independent body providing a number translation (or routing) service.

The current porting process for both landlines and mobiles is a mess - when you move your number, your calls still go to the original network and are "tromboned" on to the new network. This isn't really scalable in the long run and in any case it doesn't make sense having your calls routed through a provider you no longer have any contractual agreement with (or which might ultimately cease to exist). Not to mention that when/if we see the end of termination fees people will want to port numbers from landlines to mobiles.

If I have valid numbers and contracts with one or more telecomms suppliers, I ought to be able to swap around the call routing at will.

Hey Brit taxpayers. You just spent £4m on Central London ‘innovation playground’

Warm Braw

In a neighbourhood near you...

... you will likely find a not-for-profit organisation that provides sustainably low-cost business space for start-ups on easy-in, easy-out terms.

Around every 10 years, an "initiative" will come along that builds expensive, high-spec office space in their catchment area and offers it at an unsustainably low initial rent to businesses in the fad-du-jour sector.

Businesses that want a swanky new office start to move, threatening the long-term viability of the otherwise sustainable incubator. And then the "initiative" comes to and end, the rents in the new office space are unaffordable and the project closes and the space gets turned over to solicitors or government agencies.

And the not-for-profit that has been clinging on in the meantime by reducing its maintenance budget and pruning its staff tries slowly to rebuild its small business support infrastructure.

A lack of "initiatives" would be widely welcomed by people who actually have some experience of helping start-ups get off the ground and grow.

Open source and the NHS: Two huge disorganised entities without central control

Warm Braw

Re: Close all the golf courses.

It does seem that being a senior hospital medic comes with a sense of entitlement - that the work they've put in to get the position means they have a free pass to ignore all the rules that apply to the paeons. The biggest objections to the swipe card access system at our local hospital came from the consultants because their actual arrival and departure times would become traceable. No other members of hospital staff expect a certain amount of flexibility in their working day to accommodate their private patients. Or to avoid working at weekends (except, perhaps, being technically "on call").

And a surprising amount of that continuous training and learning is paid for by medical equipment suppliers and takes place at plush hotels with all expenses paid for.

Doctors may not be lazy, but they like their perks and they've been a powerful impediment to change over the years. It's even taken them an inordinately long time to accept the premise of "evidence-based" treatment.

Whatever their talents, effectively managing health-care provision is not one of them and they'd actually be much better employed on the golf course than in clinical management where they're all too status-conscious and susceptible to generous hospitality (which, to return to our sheep, they're not likely to get from Open Source solutions).

UK.gov lobs another fistful of change at SME infosec nightmares

Warm Braw

It never usually goes to the SMEs...

I had a long stint as an SME. My experience is that when government offers money to "help" SMEs, there's normally a large "usual suspect" contractor who receives most of the benefit (either as the intermediary through which the funds are allocated or as the service provider with whom the SME is more or less obliged to spend the money).

So, it has to be welcomed as significant progress that this particular Westminster stunt has so little money allocated to it and is being channeled as it is.

Not that it will achieve anything, other than a press release and a photo of Vince shaking hands with someone, but at least it will be a value-for-money press release by historical standards.

No TKO for LTO: Tape format spawns another 2 generations, sports 120TB bigness

Warm Braw

Lowest-cost archive medium

While tape might still be cheapest, the margin by which it is cheapest keeps dwindling. There was a time when the cost of backup media was around 10% of primary storage of a similar size, it now seems to be more like 30%. If it creeps up much higher, the inconvenience factor becomes a significant consideration.

Not to mention that if you really want to "archive" something for a prolonged period of time and have it readable by future generations, you're still better off sticking to ink on paper.

I'd like to see cheap and durable archival storage on the list of candidate projects for the longitude prize - we're going to need it.

That's precisely my point. It was good enough at that point in time and the issue of what to do when it was no longer good enough was tossed into the long grass.

Warm Braw

Re: Anyone remember the OSI protocols?

Actually, most of the then heavyweights of networking (the PTTs) were behind OSI at the time. That was one of the problems - individual participants were able to insist, by virtue of their size, on the inclusion of features that suited their own interests, resulting in "standards" with so many options that interoperability was almost precluded by design.

The more streamlined connectionless variant of OSI was heavily promoted by DEC (whose DECnet was at the time the system on which the world's largest networks operated) both in its product line and within standards bodies including ISO and the IETF.

What essentially saved TCP/IP at the time was not the force of massive heavyweights, it was a chippy little upstart company, cisco, that could offer some immediate price-performance benefits assuming a 32-bit addressing scheme, and a severe case of "NIH" affecting the IETF.

Never underestimate the power of short-term thinking.

Re: Better if Google had not become involved

It's pretty much inevitable that Google and its ilk will shower money on any organisation that offers some support, or at least apathy, in return (see, e.g., http://www.theregister.co.uk/2012/07/23/google_lobby_why/) but it's not clear it's always better for a charitable organisation to have no income than to have income with strings - and that's the choice they often have in the current climate.

Of course, if Google paid what many people would consider to be its fair share of taxation, then this could be used for the public good without corporate strings being attached. Perhaps that would be better still?

Office space outfit Regus suffers 'UK-wide' network outage

Warm Braw

Backup is not necessarily desirable...

Our local (not for profit) shared workspace outfit has a 1 Gig connection for its tenants. When it goes down, it goes down. There are several very good reasons for that:

1/ You can't meaningfully fall back from a 1 Gig connection to anything except another 1 Gig connection - ADSL is certainly not going to cut it.

2/ Having two providers and someone capable of managing BGP is inordinately expensive for the kind of business that's going to be in that kind of workspace.

3/ People have 3G and 4G phones that can provide emergency connectivity anyway.

4/ It very rarely goes down.

Now, admittedly, having a nationwide chain of desk farms changes the economics, but only for the worse - you've suddenly got to worry about redundancy in the topology of your inter-site network as well as redundancy in Internet access.

The "tl;dr" of this is that redundancy that makes a discernible difference to uptime is very expensive and there are lots of places that don't warrant it. Cost-pared temporary office space being a prime example. Doesn't stop the tenants shrieking, but not so loudly as if you asked them to cough up the cost of the five-nines service they claim to expect.

VMs aren't going away - there will always be cases in which it's convenient to have virtualisation (migration, testing) - but they were only ever the default for resource sharing because there was no practical alternative.

New voting rules leave innocent Brits at risk of SPAM TSUNAMI

Warm Braw

Similar cock-up in Newcastle

A lot of people got letters saying they'd been put on the "open" register when they'd previously opted out. Their electoral services telephones were then busy for several weeks as everyone phoned up to complain, to find out when they did get through that it was all "a mistake". They've subsequently sent out almost impenetrably worded letters that appear to suggest that people who had previously opted out would actually be on the closed register. Though by this stage, it's not clear whether their actions and intentions are in synch.

Despite the administrative incompetence, you have to have some sympathy with the councils. They didn't want to make the electoral register available to marketeers (they reasonably thought it would bring voter registration into disrepute), but were forced to do so by central government who saw it as a scheme to make £££s fast.

I've made a conscious effort to avoid having a "proper" job in IT for more than a decade. The pay's not wonderful, but the hours are great! When I do have some exceptional expense and have to venture back into the corporate world for a few weeks, my soul chills at the futility of the average enterprise and the morose grudging compliance of the staff.

And it seems to be getting worse - the expectation constantly growing that people will answer e-mails and support calls way into the night (after a day at their desk), and on holiday without any formal recognition of the work involved; the shorter development timescales and coercive (allegedly "agile") methodologies....

I'm less interested in whether the IT jobs market is growing than in why there's so little incentive to participate in it.

BBC man Linwood 'was unfairly sacked' over £100 MILLION DMI omnifail

Are the executive board who decided in a minuted meeting that 'Mr Linwood should be dismissed "one way or another"' going to contribute to the eventual cost of the settlement?

Of course not. Lessons will be learned and the people who learned them will be promoted so that they may cascade their experience from the highest level in the corporation. And cascading upon their minions is what those upper echelons seem to do best...

Facebook wants Linux networking as good as FreeBSD

Warm Braw

Re: Performance

>research given objective

Quite.

A network stack that is intended primarily for routing (or packet filtering) has different design goals to one that's intended only to run as an end system. And you can optimised end systems differently depending on whether you're looking to increase the performance of a small number of streams for a small number of processes or to get the maximum throughput for hundreds or thousands of streams and a large number of processes/threads. General purpose operating systems have to provide performance across a wide range of use cases and they're bound to be suboptimal for many of them.

If Facebook are serious about networking performance, they should really be looking at running as much of the networking stack as possible on hardware designed for that purpose. A typical server-style Ethernet adapter with ring buffers to reduce the interrupt load to manageable levels isn't really where you would want to start if your goal is to maximise performance, At extreme load, it's what you throw away that matters as much as what you process and finding out when you're run out of receive buffers that half of the packets would have been better discarded is not helpful!

Re: You can do SFN with DVB-T and DBV-T2

>a more economic model than DVB-T

That's precisely the problem. DVB transmitters ought to be cheaper than mobile base stations because they don't receive and the encoding/transmission is of a similar complexity.

If you have to get a DTV mux to every mobile base station, that's a colossal cost in backhaul. If you only do it from selected mobile base stations, then you might as well put a DVB transmitter on the same mast.

If you can do terrestrial cheaper with LTE, then there is something very broken in the distribution market!

Warm Braw

You can do SFN with DVB-T and DBV-T2

And use kit that's already deployed.

So this looks like a technical solution to a regulatory/financial issue rather than a solution to a technical problem itself.
