I am incredulous of the fact that Sky network can go down to a single geographic point of failure.
I mean, if it were a single exchange site or content provider site then I'd expect some disruption. But a single point of fibre/cable failing? At the metro/access layer surely they still have east/west resilience?
Re: Context is everything....
I took my information on the 'bad' things Mendela did from Wikipedia, so far. It says that he tried to avoid civilian casualties during his terrorist Bomb/sabotage activities.
I'm interested to read more to decide for myself what he was like so recommendations for websites/information would be appreciated. I can use a library with old fashioned paper too if it comes to it. I expect there'sat least one biography that covers these aspects of his life without bias.
Re: Dyes and Markers, Bats and Nails
Wow. Change to decaf.
Yes, telephone exchanges have been able to hot-upgrade (and hot-patch) since the early 90's without even dropping calls in progress. Further, they can roll back software releases without dropping calls in progress too.
It was largely driven by threat of damages (mainly in the US) if a 999/112/911 call was dropped as a result of an intentional maintenance action.
Networ rail signalling systems are equally important to be reliable. They usually have three parallel systems to control the critical systems, so allowing for double fault in separate system problems.
To be fair, the NATS SLA's likely say it's fine to run at reduced capacity occasionally rather thanspend an extra 5 billion to make the downtimes even rarer, adding 50 quid to everyone ticket prices.
Re: 99.9998% Availability.....
With mission critical systems the backpu solution isn't supposed to be a copy of the primary system. It's supposed to be developed separately, updated separately,managed separately. This way a bug in the primary system isn't replicated to the backup.
There is a difference between the primary system availability and a Disaster Recovery system. DR is used when the primary systemand it's resiliance completely fails. The problem here is the DR system and processes didn't work. That system would not be provided by Frequensys. Probably it's more owned by NATS themselves.(the original card shuffle systems..)
Re: One million lines of code
What we don't know is how many times the resilience HAS worked i.e. the primary system could have failed hundreds of times over the years ,with the resilience kicking in perfectly every time until now.
We just don't get to hear about those occasions as there's no impact.
Re: The first hurdle....
" I even went as far as getting a masters. Which I regret because I do honestly feel real world experience in the industry I am in would of paid of significantly."
Sort of agree: I don't recommend anyone do an engineering Masters if it's about getting a pay off (monetary or otherwie) at the end of it. You have to really love and be interested in your field to do a post graduate degree.
But as a CompSci guy, my view on this is blinkered. I understand that medical, architectural, business and finance post graduate degrees are somewhat more required to enable workign onthe more interestign aspects of those professions.
The operators just need to ensure that every RFP, RFQ and RFI they put out clearly ask the responder to state how their proposal aligns with the overall principals of NFV.
They then need to start awarding contracts to those they feel who are making the most progress. The operators need to be ready to take risks on this and go with emerging stuff. If they don't buy anything from the vendors until ALLtheire requirements are met then it's too big a risk for the vendors to develop for years.
Re: Nice try
The deluxe version powers a light bulb all night. It comes with a really long rope and you hoist it up to a pole sticking out of the top of your roof.
The non eye-sore version comes with a really long rope with a bucket onthe end. You dangle it down a well. If you need less power, butto last longer, you use the bucket only half full.
Re: Europe is slightly better
Inexplicable truth, competition seems to be working in Europe to keep prices relatively low.
Unless I'm missing something (which is likely). Are communications subsidised in Europe?
Could Stanene be used as a regular electrical-power transmission wire? I realise that the charge can only go along the surface of it, by design. Does this mean that it cannot scale to be useful for passing high voltage current over long distances?
If they can find a way to make lots of Stanene layers or strands all bundles together could that lead to greater surface area and allow for this?
Re: Chinese government really has only itself to blame?
If MS did decide to extend security support for desktop XP, then would they be open to people asking for their money back for the Windows 7/8 upgrade they had paid for?
If I ran an organisation that just spent millions on an OS upgrade, primarily for security support, then I'd be very upset if my competitors found they could then stay on XP and spend nothing.
Re: Unusual Case.
It's ironic that China originates a large portion of the security attacks onthe West, targetting XP vulnerabilities.
By extending XP support, they help keep the Western businesses and households running XP for longer too, maintaining their lucrative hack targets.
PE1: > no conspiracy mode <return>
MS should simply take Windows 7 and rename it 'Windows XP Service Pack 4'. Instantly everyone is happy. China gets security updates for years to come, users get to apply the 'update' and stay on WIndows XP. Business gets to sigh relief that they aren't makign a massive change that puts their revenes at risk.
It's all about perception.
I never thought that drones would be delivering from delivery centres. In my head I pictured the delivery van driving into the neighborhood, and the driver then deploying the drone for the last mile.
But, I'll accept that I got it wrong.
In terms of shooting the drones, I figured that they would be shot after dropping off the parcel, which they have to do from some low height so as not to break it. Or are they going to use parachutes from 100ft up?:)
I suggest that the shooting down of drones is already well understood by the military, who have to have a plan against use of drones in the battlefield. Thinking of ways to bring them down from range, in a built-up area, will be fun to some. Home made directed EMP?
Don't be afraid of trying embedded hypervisors. It can make your brain hurt a bit, but is very effective at saving you time.
For example, on my lowly laptop (HP Elitebook 8640p) running Windows XP with 4G RAM I started by putting on the free VMware workstation. Then I loaded ESXI into a workstation instance, and created VMware instances in that.
This runs slow, but my purpose (and yours) is to experiment with VM, not to run applications efficiently within sessions. Getting virtual switches set up and understanding how to make something at the top/XP layer (Vsphere) talk to ESXI two layers 'in' over IP all within this virtual world was fascinating for me.
It's possible to set up whole networks within a single machine, with switches, routers, hosts etc all talkgin without knowing they are in a playpen. It's cool.
Yes stop wasting my licence fee money on 3DTV please Mr Beeb.
Start wasting it on 4KTV instead immediately. Oh, you are already planning it? OK.
The US government spook agencies will be all over this to ensure that the agreed standards allow ongoing call monitoring. In fact, they'll be rubbing their hands together as it is much easier for them to accomplish in a world of all-IP.

Re: Nomin..ally paying attention to what people asked
Oh, I agree. Ease of user input/memory/typing is a poor argument. But it's the only one I've seen discussed and posted so far in the online debates.
Then there's another (poor) argument that the internet shouldn't be held by by domain name restrictions but rather should be more 'anarchic'. That restricting domains names is another way business is trying to commercialise the internet for itself rather than leaving it open to the masses. I don't subscribe to that view either.
Re: Nomin..ally paying attention to what people asked
"It just means now I'll need to maintain 2 domains in .uk at least for the foreseeable for each one I held before."
I don't understand: who is forcing you to do this? If you don't have .com, .co.uk and .org etc. at the moment then why do you need multiple names in future? Your existing organisation name could already have many shortened forms without the new extension too?
To help with your benefit question: the benefit is to your internet community who need to type it in. Fewer characters make it easier to remember, faster to type, and easier to type without mistakes (on a fiddly smart phone). Organisations want to make it as simple as possible to be reached by their user base, I have to presume?
This man writes the truth. They are listed as one of the top UK 'not for profit' organisations in the UK, and their 2012 report goes on and on about the charitable donations they made, typically to help with internet based concerns.
Also, look at the figures on their balance sheet. Tiny numbers. This is no Microsoft.

Re: Again with the PS4 ad?
You have one now. I donated mine to you, so it's yours.
I'm just keeping it safe for you.
The rootof the problem is that this is all about Operations.
The guys that specify what they want to the vendor, the guys that control the purse strings, are rarely interested in making life for Operations staff better. This is because buiness cases pass when they are about revenue growth. Cost reduction is far harder to prove and make look attractive.
Cost reduction business cases need to be done by the Operations team. But most operations teams are not populated with folks who are thinking of ways to make their group more efficient, and hence reduce the need for staff.
The software exists to do all that you ask. Including analysing the collective alarms and instructing what to do about it based upon rulesets. You can even configure the monitoring software to integrate with your provisioning/maintenance interfaces and take corrective action automatically if you dare. But it all takes Professional Services to tailor it. Then more Services to migrate you onto it from what you have now. Then more services to upkeep it maintained and keep tailoring it as your network evolves.
Unless you invest in people to train and do it in-house, but then that's even more OPEX to justify in your business case, which is the hard bit for Operations guys to do in a way attractive enough to the business to sign off.
Re: Watch out there's a lawyer about
Maybe as electricity is provided as alternating current, they only provide it to us for half the time. The other half of the time they are pulling it back again. (lol)
So we aren't getting to keep any of the electrons they provide, just the electrons' energy? Or something?
I am sorely in need of 10 minutes on WiKi to refresh my O level physics knowledge :)
Isn't what you described 3D carving rather than 3D printing?
Re: Monopoly can be a hard game ..
"The only winners with BTC are those with the sense to sell up and get out when the price is high."
I disagree. I have needed to buy things (legal things) on the internet recently. I was able to buy bitcoins, and then use them to buy the items I wanted. Which have since been delivered no problem.
So, for me, I used a bitcoin service and I am happy with the result. I'm not a speculator, but I've 'Won' in the fact that I've got a service that was easy and nice to use and I got what I wanted.
Bitcoins isn't all about making money, ya know.
Oculus Rift support?
Ah Velv, You put it so well. And then you fell down at the last hurdle. If you'd just managed to hold yourself back from that final sentence it would have been great,
'Hi, I work for a Law Enforcement Agency. We have heard about your Smart meters deployment, and there's a few requirements we'd like to see added to your must-have list. As follows:
- A process whereby we can request usage data from you, with appropriate warrant, in order to prove likely human activity in any premise at any time.
- An ability to cut-off power to a house upon demand (via warrant), aiding us in premises raids.'
The above is obvious. I'm sure they wont ask for a microphone to be installed though :)
I don't know if Bitcoin (or any other) is a scam or not.
However, I have (under instruction from my far more knowledgable brother) set up a bitcoin wallet, been 'gifted' 2 (or so) bitcoins from that brother, and then sent them to someone else. In return I've received a used computer graphics card through the post.
I'm not making any money from these things, but as far as used for transactions it's ticked my boxes and I don't seem to have lost out any where. So it can't be ALL scam.
I wish I was clever enough to understand it as well as my brother. Sigh.
Re: We need a change of marketing
Why multicast support? TV broadcast is, these days, about users wanting to watch things in their own time, any time. I think operators are more interested in content cacheing servers to reduce core bandwidth than in multicast now
I've only seen one commercial use of multicast in all my years so far. For multiple-locationsimultaneous announcements. Is BT or anyone really considering it's use for IP broadcasting now? Interested if so.
For those living in a low-bandwidth area in the UK: How much would you be willing tp spend per month to get premium internet speeds (say, 50Mb download 10Mb upload) ?
If the majority are ok with around £70/month for 24 months minimum, it may become viable for operators to offer,
If not, then your access wont improve anytime soon. Yuor postal services are going to go the same way, as soon as the PO privatisation goes through. Sorry.
In my career choice the BOGOF offers are few and far between. However, we specialise in bundled deals instead which are very popular. We are well trained in convincing our customers to upgrade at the point of sale.
Our top of the range deal is to large on a McCheeseburger meal.
My priority is to avoid having to carry two phones (one work, one mine). Therefore dual-SIM offerings are of high interest to me. I suspect UK retailers don't like to push dual-SIM models (e.g. Samsung Galaxy Grand) because it goes against an ethos of network tie-in.
I've not seen much on dual-SIMs in UK media. Plenty in Indian media though :)
Re: Not a problem
Bosch would argue that it's not their fault that the FRAND agreements didn't account for this happening.
LIke taxation laws: dont' blame the organisation taking advantage of the environment. That's human nature (unfortunately).
"1,438 affected customers" or "1,438 affected customers, that we know of. Our list of the others got eaten by the dog. Honest."
Silly comments are welcomed by me, as long as they are funny too.:)
I'm wary about spending on early UHDTV's whenthey hit the stores, since the overrated (IMHO) 3DTV revolution.
i.e. sounds good, but is it? really? This article opened my eyes (heh) to thinking about more than mere resolution.
Re: Leave your phone in the direct sun?
About 1 Billion+ people living around the world without decent reliable power supply like the idea. Does that count?
Re: I did not cost the council one penny
Let's hope the voters in Glasgow hold their councillors to account.
It is the councillors who hold their civil servants to account, unlimately being able to get rid of the CEO through a vote of no confidence if he/she hasn't satisfied them that suitable action has been taken.
If nothing happens, and the councillors are still seated this time next year, then blame the voter :)
Probably the IT is outsourced. The ITcompany gave a quote for encryption, which was sniffed at by the council as costing too much so declined. The council will argue that Central Givernment cuts meant they didn't have the resources to pay for betetr security. Blame will be passed around and diluted between the workers. Only the voters hold the true power to get something done about it.
Whilst Freesat is all well andgood, it doen't work in heavy rain, Snow or Hail conditions. So it's fine except between British September and May.
The problem exhibited here is of communication. The IT guy, who was dealing with the vendor, didn't understand the requirements of the Owner/Manager well enough to be able to specify them to the vendor.
The Vendor and IT guy therefore both wasted time in scoping a high-available system. The owner wasted his time in reviewing a proposal which didn't suit him.
If there's doubt that the IT guy will reflect the ownerr/manager position, and the owner/manager can't be accessed directly, then perhaps it will bebetter to create two proposals so he has some choice :)
