Windows Live Mail?

"in 2017 found Windows Live Mail had one per cent market share"

What has this to do with the Mail app in W10?

WLM has been abandonware for years now and difficult to get hold of. I haven't spent much time on trying it out on W10 (upgrade from W8.1) but it didn't seem happy.

Still running it under W7 and W8.1 because it reminds me of Outlook Express and I like the user interface.

'A sledgehammer to crack a nut': Charities slam UK voter ID trials

David Roberts

Who might be at risk of fraud or be disenfranchised?

Firstly, houses of multiple occupancy such as occupied by students and poorly paid workers. Only one name on the utility bills. Secondly a house with a large family; three generations, perhaps, but only one name on the bill. Very hard to provide ID.

I assume that the homeless are considered unsuitable to vote.

Ethnic minorities and especially those with a poor grasp of English and local law. They may find that someone helpful has registered them as voters by helping them fill out the forms (or doing it for them) and then helpfully collected the voting card for them and used it to vote for them.

Traditional home owners should have little problem with voting; the most you might get is someone using your polling card when you are away (or in hospital, perhaps). It is the poor who don't own or rent their own home who are most likely to be disenfranchised. People living in temporary accomodation, hostels and the like.

A robust system of ID cards would help to solve many issues to do with disenfranchisement of voters. The Police State issues associated with ID cards may be too high a price to pay. Would you fully trust the current government not to abuse this system in any way?

However, if you go on holiday to France or Spain, for example, you have to produce ID whenever you book into any accomodation. They still seem to manage to be reasonably democratic. So who knows?

So just like a mirror to see round corners

Except not smooth with a reflective background but rough with a potentially non-reflective background.

I can see this working in USA cities with grid pattern roads and glazed shop fronts because meat sacks can do a very similar trick. Using a rough barked tree as a mirror would require serious illumination coupled with a very high ability to discriminate between reflections from the target and from noise.

I assume that you can tag the light (or other wavelengths) you emit so you can detect which incoming light is a reflection.

I would have thought the first stage would be to detect the reflections round the corner from other light emmiters. Such as the meatsack trick of seeing car headlights reflected in the store front on the corner. Can cars do even that yet?

World's biggest DDoS attack record broken after just five days

Re: ISPs could mitigate this - car MOT

Just one small flaw in your plan. The MOT helps to secure road safety in the UK from dangerous cars on the UK roads and is policed in the UK where the cars physically are.

How do you propose to enforce an MOT on servers all over the world and completely outside your jurisdiction?

If you can't knock on (kick down) the door then you can't tackle the problem at source. You have to police the borders (just like illegal goods) which is the point where you can take physical control.

So having ISP routers acting as border guards is probably one of the more effective ways to address the problem.

Interesting story

However my initial take on it (and nothing so far seems to contradict it) is that old trusty was replaced with new shiny but IT was far too special and busy (or perhaps not even involved) to perform a proper customer handover.

Otherwise somebody would have done the "This is how you dock and undock, and you can use it stand alone like this." talk.

I assume some budget cutting strategy where you throw the kit at the punters and hope they will help each other to sort it out. Followed by "but surely everyone knows that" when the support calls come in.

WTF?

Much of what was reported seems strange.

Running a test bed for viruses and anti-virus packages (presumably just firewalling the reporting channels) doesn't seem to fall into a major crime area. Nor does encryption technology (at the moment).

If it was clearly marketted as a service to develop viruses and conceal them then it makes it look dodgy, but apart from that you are close to making running your own development server with crypto capability illegal. Is it illegal to test if code triggers an anti-virus package? Or is this all based on intent?

It reads as though the headline is there to boost law and order's news profile and pretend they busted a mega criminal instead of someone playing a minor role.

An employee for tax purposes

Last time I looked there was a wierd legal fiction that a tax finding did not confer any employment rights so the deemed employer got off scot free.

The poor sod of a deemed employee had to pay the same PAYE and NI as a real employee but got none of the benefits of sick leave, holiday or pension. The taxed income then went into the personal service company where it was all taxed again. Absolute bare faced robbery.

I doubt that it would have gone quite so easily if the BBC was fighting to avoid 7 years of holiday pay and pension contributions. No idea who copped for the employers NI on the deemed employment. Wouldn't be surprised if it was the deemed employee because HMRC must get the money regardless.

Home fibre in the UK sucks so much it doesn't even rank in Euro study

David Roberts
Windows

Picking up a few points

"If the clowns at Ofcom don;t address this soon, then people getting new Talktalk, Vodafone or Cityfibre connections will be permanently locked into single ISPs providing high speed broadband at whatever price they like. Customers of Virgin Media will be familiar with the "benefits" of this lock in, such as appalling customer service, ineffective technical support, a monopoly mindset, and rampant price increases. And once an area has one high speed broadband network, who would invest to duplicate that? Nobody in their right mind."

and

"One of the main reasons given by Openreach for not immediately running FTTP into every building in the country is the cost - they have a point, digging up roads, sending blokes up poles with reels of stuff all cost money. Billions."

So riddle me this. I have a VM fibre/coax service and have had for years. I've always found their customer service (at least for line faults) to be outstanding. Same for previous house half way across the country for 4 years. None of this crap about charging for an engineer's visit either. I think the service you get very much depends on your local office. My package is good for 200 Mb/sec but I'd have to agree to a Superhub 3 so I am staying on my original Superhub with a solid 160 Mb/sec and sometimes more. Currently looking at a free upgrade to our old Tivo which is getting a bit long in the tooth.

I was prompted to look for alternatives because the local telephone poles have recently sprouted (via cherry picker) reels of black something and a black block with loads of sockets on the top. The contractors said it was fibre but they didn't know when the tails would be pulled back to the exchange.

Online checking also shows that my location is supplied with FTTC, which implies that there is already ducting running fibre, although not that it has any spare capacity.

Trying to track down a ready date established that nobody apart from Openreach knows anything about this. One person said that if you had FTTC available it was very unlikely they would roll out FTTP as well. I have a query in with OR and they say that they will get back to me within 28 days.

Anyway, in my specific instance it looks as though fairly shortly I may have the choice of VM, FTTC and FTTP.

Which suggests that the quotes above may not apply to everywhere.

To my cynical mind it also suggests that OR may be rushing out some installs in quick and easy locations (very close to the exchange, fibre already run to the local cabinets) for a quick win in the numbers game so they look to be ahead of the competition.

Hate to ruin your day, but... Boffins cook up fresh Meltdown, Spectre CPU design flaw exploits

David Roberts
Pint

Re: Don't panic, "No exploit code has been released."

Definite lack of shit donation over here as well.

First there should be a realistic (!) proposal of how to fix it.

First stage of that is to produce a new/upgraded/different architecture which has security against these flaws built in. Followed by implementation, testing, running up the fabs, producing the suport chips and motherboards and starting commercial roll out. Not gonna happen this year.

Next stage is to recognise the enormous real estate of vulnerable hardware out there and that there is no economy in the world which can afford to ditch all that and start again even if some mad manufacturer was prepared to ramp up production to meet all new demand plus full replacement.

In the mean time all demand for new/replacement computing capacity will have to be met from existing architectures, constantly increasing the real estate of vulnerable hardware.

Not fair, cry the commentards, that means you are forced to buy dodgy hardware from the people who designed it to be dodgy.

So come up with an alternative which keeps feeding society's insatiable demand for cheap computing and which demand resulted a long time ago in the dominance of Intel as a single supplier. You get what you pay for. Or don't. If there were say four different competing architectures all at similar volume you could afford to drop one and ramp up the other three.

Nobody has yet made a reasonable commercial case for curing Meltdown by ditching Intel in all new machines and letting ARM and AMD take up the slack. Because there just isn't the capacity. That is using existing factories with fully functional production lines.

So enjoy you ranting and beating of your manly (or womanly) breast in outrage. [Um....nearly wandered into mind bleach territory there.] However come up with a viable alternative or accept that we now have an ongoing cycle of software mitigation in the same way we have with all other software products. Coupled with a performace degradation in heavy use scenarios.

Life sucks. Deal with it.

Since I can't see any way that I can solve the problem or even influence the outcome, there isn't much point in wasting time worrying. It will either be fixed or it won't. Meanwhile I think my time would be more productively spent sampling a few brews.

Payload?

Roughly highest payload cheapest per mile.

Air

You note, of course, that the slowest is the cheapest.

So the payload of a drone to go between distribution centres must match large lorries which do the job now. Or a number of drones combined must be both faster and cheaper than road transport. Meaning an order of magnitude cheaper than small to medium planes.

Nobody so far has really explained the cost benefits of flying drones over driving lorries. Lorry drivers aren't expensive.

Replacing local delivery drivers with drones would be a "brave decision".

Meltdown's Linux patches alone add big load to CPUs, and that's just one of four fixes

David Roberts
Headmaster

Re: Patches applied yet?

Think about a turnstile.

If the rotation is slowed by 10% then each individual passing through will go through slightly slower.

If the turnstile is only used 40% of the time and there is never a queue then the change in throughput is going to be negligible.

If the turnstile always has a queue then the processing through the turnstile is going to be noticeably slower.

In computing terms your process has to be very cpu bound for the patch to have a major effect. If this was the case you would see the cpu running flat out most of the time. Most home systems don't see this so the patch generally will not make a noticeable difference.

If you are usually running at 5% cpu a 10% overhead will take it up to 5.5% worst case. A slowing of 0.5% in the performance is not usually noticeable.

TalkTalk to splash £1.5bn laying full fibre on 3 million doorsteps

David Roberts

All or (virtually) nothing?

We have VM cable with 12 up 160 down.

The OpenReach line checker shows FTTC with a maximum of around 50 down.

Telephone poles are sprouting fibre terminations with reels of fibre waiting to be pulled through the ducts.

I have no idea if Talk Talk are planning a roll out of fibre to add to the mix. Noting that unless they get access to the poles there is likely to be a lot more cost compared to the OR deployment. This in turn makes me wonder if OR will quickly roll out FTTP in any area where TT apply for planning permission (or whatever) to dig up the roads and pavements.

David Roberts

Helpful installation

This is one area that VM shine (at least in my local area).

They ask you which room you want the TV in and which room you want the router in and then run the cables as required.

They don't charge for engineering visits in general, either. When our builders hit the cable whilst doing a bit of block paving they just came out and fixed it.

The possibly lower up front cost of copper/fibre services may be attractive but it seems that the VM subscription includes free engineering support.

Re: Another lease extension for the life of copper access

Nice to know that I'm living in the distant futoure with my solid 160 Mb/sec VM cable service.

I am eligible for 200 Mb/sec but that would involve having the crappy SH3 so I am sticking with my original Superhub in modem mode.

Unless things have changed recently wireless is "round robin" so you don't have all the devices transferring data at the same time like you do with wired. So you would need high speed devices to get a slower speed average throughput on a shared router. No wireless device is likely to hit anywhere near the rated speed when contending for access to the router.

Noted that even with 160 Mb/sec download speed iPlayer and Netflix have buffering issues at times so the whole network neds to be able to support these speeds.

Helps to have a Gigabit switch under the stairs and all rooms wired, of course.

Re: you're peddling cheap, low quality, high street tat

"Once upon a time programmers were engineers. With a degree. From a proper university."

In your fixed view of the Universe, perhaps.

Back in the day, most large organisations (and a lot of smaller ones) trained their programmers from scratch.

When I came out of University in the '70s with a degree but no direct employment prospects in that discipline I searched around for any job available.

One was for a computer salesman. I obviously wasn't a natural (or even unnatural) salesman but part of the interview including a programming ability test. I scored highly and was passed on to a software house who decided not to employ me because the boss was worried that I would take the training then head back to academia (which does show a distinct lack of commercial awareness).

Anyway, that set me off looking for programming jobs and I was recruited by a major public body building a programming team for a new project.

The recruitment favoured graduates or at least people who had spent at least a year at University. All sorts of disciplines including astronomy IIRC. Everyone was trained from scratch in COBOL and were generally productive within 6 months or less.

So no "real engineers from real universities" involved at all.

You may find that many of the commercial programmers out there today have no formal engineering qualifications, possibly not graduates from a "real" (or even Unseen) university. So what? That is what "introduction to programming" courses are for.

Personally I found programming deadly boring after the first six months to a year and moved on to the more technical aspects of computing. It takes a special kind of mind to work long term at programming, especially maintenance programming. Not me.
