Re: Email address?

It depends how far back you go!

I was responsible for the ibm.co.uk mail domain for some time, and when I first used it, it was about the only way of getting SMTP mail into IBM UK. IBM was very Internet and open network protocols averse in the early '90s, as they were actively pushing SNA.

IIRC, we were only offered SMTP type addresses through ibmmail and NOSS in about 1992. It may have been there before, but we were told that the system that did the mapping could only cope with a limited number of users.

Re: Email address?

NOSS/PROFS was an email system, it just wasn't anything like the other things that were around at the time, and until the middle of the '90s, it had limited connectivity to the non-IBM world. But then, neither did anybody else much unless you used UUCP mail.

In fact, I'll go one stage further. It was an office productivity tool which would do email, calendar and meeting management, document indexing, organization chart and telephone directory, and also allowed you to escape to a document preparation system using Script.

If you could put up with the 3270 interface (which was a challenge if you had used anything else beforehand), it was actually extremely functional.

When I joined IBM in 1990 as an already experienced UNIX support specialist (this was when the RS/6000 and AIX 3.1 was launched), I hated NOSS, RETAIN and EHONE with a vengeance, but once I bothered to learn how to use them they all became perfectly usable. Although it is archaic, RETAIN is still one of the best problem tracking systems around. Knocks REMEDY into a cocked hat, once you get past the layers of GUI and HTML crap screen scrapers that modern IBMers prefer to use (note- I'm working for IBM as a contractor at the moment).

I left IBM before Notes was deployed company wide, but now have to use it for all IBM related mail. I can't say that I like it, because I'm sure that there is a lot that it can do which I don't know how to use (here, take this Thinkpad and start using it - uh what was that? Training? Don't be stupid. Now get back to work!)

I'm sure that it is usable, but I find that I end up banging my head against the desk all the time.

Oh. OS/2? Yes, I did quite like that, especially the PMX X server that could turn it into a flawed but useful workstation in a UNIX environment. And that was a free download!

I still wear my OS/2 Warp launch tee shirt once in a blue moon for nostalgia sake.

BOFH: The Great Patch Mismatch

Where I work they use an argon/nitrogen mixture

branded with the proprietary name argonite.

Supposedly, if the oxygen concentration drops below 15%, almost all fires are extinguished.

The system is calibrated to drop the oxygen content to about 12.5% by displacement, which will keep you alive if you are caught, but is probably quite uncomfortable.

I don't intend to try it, not after going through an oxygen depletion experiment at school many years ago (probably not even allowed now), where I breathed the same air over and over through a CO2 filter. You don't start breathing heavily (it's the CO2 that makes your body believe that it's suffocating) and you just can't think or do anything. I was told that I looked very silly by the rest of the class not able to answer even the simplest question. Fortunately, the teacher liked me enough to take the mask off before I passed out.

Re: Christ (oops!) bloody religion again??? @Richard 81

I'm not sure that you understand how much is lost in translation. I tried reading a translation of the Quran myself (I'm pretty much agnostic and was doing it to try to understand the background to the religious conflicts, in the same way that I've read the Bible and the Book of Mormon), and the mess that was the translation I was reading must be poor, because it was difficult to read, and contradicted itself within a few pages. I got about a third of the way through before losing interest.

I've been told by someone who can read Arabic that it is a very difficult language to translate without losing some of the meaning, because the structure of the language differs in several fundamental ways from European languages. I cannot confirm this from first hand knowledge, but I am prepared to believe it.

Thus, I believe that to get the maximum benefit of the Quran, it is necessary to learn and understand (grok?) Arabic, such that you don't need to translate to comprehend.

Re: The one advantage that physical retail has..immediate availability

Being a person to whom if it works then it's good enough (form follows function), I've ended up getting most of the white goods I've needed to buy recently (mainly washers and driers) from our local Co-Op.

OK, you often only have a choice of 1 or 2, but they take are prepared to sell the display model if they don't have any 'out back', and give a discount and full warranty if you end up with the display model.

Walk in (even quite late at night), see what they have, check whether it should do the job, go to the till, get the duty manager paged, purchase, and take out to the car, often being helped by the manager themselves! It's that simple (helped by the fact that we've got an MPV).

You have to put up with a small choice, and the brands that they stock, but so far, we've always got something that will do the job! I know that will not suit everybodies shopping needs, but it works for us.

In reality, not having devices available in stock is a direct concequence of too much choice. As pointed out bu a previous poster, it is simply not possible to keep several instances of every item if you have a large range being displayed, especially when it comes to white-goods.

In some respects, I would prefer to have guaranteed availability in store of a smaller range flagged on the display, with other items on display carrying expected delivery information. This makes sure that immediate availabillity can be part of the customer decision up front, rather than making it something you have to initiate a dialogue with the sales person in order to find out that they have.

The other thing I find amusing when looking through the spare parts listings for white goods is how many of the different brands are built in the same factories using the same parts, and only differ in cosmetic detail. It would be so much nicer to not have the same device with a different brand confusing the potential customer and cluttering up the display in these sales-warehouses.

Ten Linux apps you must install

Peter Gathercole

WTF?

Re: Linux with windows? Weird

What on earth were you running this on!

For it to need to install x11-common, x11-utils, x11-server etc must mean that you are using a Linux distribution that DOES NOT PACKAGE A GUI! AFAIK, unless you are running a GUI which drives a framebuffer device directly, X11 MUST be installed on your system.

What is this, some crazy hair-shirt hand built system? Or maybe your package repository is corrupt. Is the Linux kernel listed in the redacted portion of the list? Maybe again, do you normally use apt-get to manage the packages on the system, because I suppose that if you were using Yum or something rpm-ish, the repository may not be populated with a correct list of installed packages.

Anyway, in this day and age, 99.7MB is actually a fairly trivial amount of space. Your average Microsoft Patch Tuesday will be larger than this. I would hazard a guess that this is a system with Gnome as the GUI, and much of what is being installed are the KDE packages that do not normally get installed on a Gnome system. But X11 should still be there!

Windows Phone 8 reboot woe causes outpouring of forum misery

Peter Gathercole
Silver badge

Re: How much worse can it get?

What universe do you live in? Windows does not have support for all devices built in. That's why you need all of those shiny installation CDs whenever you add a new piece of hardware.

I suggest you try taking a disk from one vendors's system, and sticking it in another from a different vendor (although make sure that you do not switch from a 64 to a 32 bit 32 bit system if a 64 bit kernel is installed). I would be almost completely certain with a Linux system that it would boot(*), and as long as it has a VESA compatible graphics mode, that it would come up with something like a full res screen, with all disk and 99% of network adapters working without problems. I've switched my laptop disk between systems more times than I can count.

With a Windows system, I would give odds of only 50-50 that it will even boot except in safe mode, and if it did, the screen would probably default to 640x480 16 colour mode, with sound and network adapters not working until you stick the correct drivers on. I've had these problems every time I've changed a mobo in a Windows system, although I will admit that I've not done it since Windows XP.

The difference is that Linux treats almost all hardware as not being needed in the stock kernel, but has the hooks to allow it to install software modules for devices detected during the boot process. This means that unneeded device drivers do not get loaded into the kernel. This makes the kernel relatively generic. All you need is for the modules to be present in the boot volume, and known to the device configuration method. Of course, some devices need additional software to function correctly, but I would bet on any Linux distro from the last seven or eight years having better support for more devices out-of-the-box than Windows.

(*) The exception is 32 bit Ubuntu Precise Pangolin (12.04) or later on a system that does not support PAE, unless you've installed the non PAE kernel. Bad Canonical. Very bad.

Re: Reboot culture

Yah, That "Keyboard nor found" error floors me every time, but unfortunately, it's a BIOS error, not a Windows one. It goes back to IBM PS/2 systems, I think, but may have been in the original IBM PC as well (I don't have anything that old to test on, I threw my wife's 5150 away when she got a Tosh T1000 laptop for £25 about 10 years ago).

My youngest son has a different problem. He has a Microsoft Sidewinder mouse plugged into a Windows 7 system, and after about an hour, it stops working. Unplug and replug, and it works again. Plug it into ANY other OS (not tried Windows 8, admittedly), and it works perfectly for ever. And this appears to be a well reported problem. Still, it's a bit off topic.

Cashless Comet to close 41 stores, axe 500 jobs

Peter Gathercole
Silver badge

I remember when...

as a student, I bought my first real HiFi (OK, it was an Amstrad seperates system with a Strathearn [who?] turntable, but was still listed as HiFi in the magazines) from Comet.

The reason I used Comet was the fact that at that time they were box-shifters, selling end-of-line kit at well below the original prices. As things had a longer lifetime then, it did not seem too much of a problem to me, and it meant that I got something that approximated HiFi at a price that I could afford.

That's how they made their name. I was very disappointed when they became a mainstream supplier, but I guess that is where the money was.

Come to think of it, that Amstrad IC2000mkII amp may still be in my loft, heavily modded after being used as an emergency PA for a small venue.

Power to the people - if you can find a spare socket

Peter Gathercole
Silver badge

Never come across this problem

Everywhere I've worked in the last 25 years has always had some (although to be fair, sometimes not enough) standard power sockets on their desks.

Where I am working at the moment does have some unusual power sockets, but that is because the workstations are on a central UPS, and the powers that be don't want other devices plugged into that supply. There are, however, at least two ordinary sockets per desk.

I do remember the bad-old days, however, when desks were free-standing pieces of furniture without a provision for power, and all that was available were wall sockets. But then, back in those days you were lucky if you had a phone on your desk. There was no desktop electrical equipment unless you had a printing calculator or a mains powered dictaphone, or a lamp! (BTW, these were the days of batch environments, with jobs being written using punch-card decks, and output on fan-fold paper).

At one place I worked, an office refit that was done for a building that was originally built in the '70s, and modern desk furniture was installed, but they didn't upgrade the floor electrical wiring. Once they started putting PCs with large CRT monitors on every desk, they found that the floor wiring presented a fire risk because of excessive power draw. Electrical engineers came around one day with spot temperature meters looking for hotspots, and then isolated about a third of the floor from the power until they could re-wire the whole floor. Caused havoc, as this was the floor occupied by IT support!

Re: Orange are the same

When I switched from Virgin ADSL to Orange (now EE, if you believe the stupid mailshot I got earlier in the week), the improvement was dramatic. Everybody in the house commented how much better they were finding it.

After about 3 months, the throughput started dropping, and even though I upgraded the line to ADSL2+ (which was strange, because when I switched, I'm sure I was sold 'the fastest service available from your exchange', but still had to upgrade to 2+ later), it is pretty poor. Pretty much any streaming service I have tried stutters, and not always at the times of day you would expect it to.

I must go back in my firewall throughput logs to see where it really dropped.

Re: Engineering and Scientific Software

Agree, but how many people run such software away from work?

I have one friend who does such a thing, but he is a computational scientist with few family commitments, and takes much of his work home with him!

Manufacturers just have to face facts that computing devices are going to (have?) become commodity items like entertainment equipment, and adjust their businesses accordingly, rather than trying to keep stuffing unnecessarily powerful systems into the consumer channel. And if this means that 'bleeding edge' systems for people like you become more expensive, that's just tough.

Must of us here do tech in our day jobs. Unlike the stereotype, many of us have families that keep us busy when we are not working, and provide higher priorities for use of money than the Shiny.

Find me a home system that is cheap and I can keep running with minimal effort for a few years, and I, along with I think many of the other people here would bite your hand off to get such a system.

I have been running old kit for a long time. I have been using my current main laptop for about 5 years, and it was second hand when I bought it. I think that the end of the road for that system is neigh, as it will struggle running Unity on Precise (but may run Mint!), but if I stuck to Lucid, it would probably remain usable for most things until that runs out of support, or the memory slots finally fail.

Whilst compatibillity is one of the strengths of Intel centric computing

I really miss the diversity of different manufacturers making radically different machines.

I remember in the mid '90s when all of the articles in the PC magazines were essentially describing the same machine (IBM PC compatible) with the only differences being the clock speed, memory or disk capacity, processor generation or case-colour. It was the point that I stopped reading the magazines on a regular basis as computing was no longer exciting.

I am not looking forward to the point where Intel have driven everyone else out of the server-processor market, and just hope that ARM can continue to make inroads into the desktop and mobile market. If Intel can achieve total dominance in all segments, then expect innovation to slow-down as the accountants try to extract more revenue out of each processor generation to maximise the R&D costs.

A bitter spill to swallow, or 'how to smeg up your keyboard'

Peter Gathercole

Irn-Bru

is far worse than Coke. So much sugar, and I really don't know what gives it the orange colour, but I would not be surprised if it glows in the dark!

One of my kids ruined one of my beloved IBM model M keyboards with it. Despite soaking the keyboard, I did not get it working. Next step was stripping it down, which needed a log reach box spanner and side cutters as well as a screwdriver. I think that the reason why these keyboards last so long is that they are never meant to be dismantled.

Inside the plastic case is a huge lump of metal to give the weight, and 100+ buckling springs with plastic rockers that provide the unique feel. Once these are stripped, you are left with a sealed plastic unit with a membrane inside just like everyone else's keyboard (bit disappointing, really). Cutting the plastic heat melted rivets on this unit, and opening it revealed the membrane, which was so thoroughly stuck with orange gunk that the conductive tracks were pulled from the membrane even though I was taking extreme care and using water to dissolve the gunk. Tried conductive paint to repair the tracks with no luck

I wish I had tried the washing machine trick. I've now only got one model M left, and the kids are not getting anywhere close to that!

3D hidden line graphics on a 2MHz 8 bit micro was eye-poping back in the early '80s. I remember someone bringing in the first copy seen at the BBC micro users club I used to frequent, and it drew a huge crowd.

I had been playing around with wire-frame graphics myself at the time and I quickly realised that they were using a very quick-and-dirty algorithm to draw the lines, but I never did figure out how they managed to work out whether a line was visible or not at the speed that it ran at.

Re: @dz-015 - Multiplayer game based on Elite?

@Mark 65

Even though when I started playing Elite I would BUY (no cheating here, except to make a copy of the disk - not a trivial task until sector-by-sector disk copiers for the BEEB came along) a docking computer, once I found the Bitstick worked as a controller (or indeed any other high precision joystick, I could do the same with one of the BBC analogue joysticks with an extension on the shaft made of a ball-point pen body), I completely ignored the DC.

At computer club events, I would quite often wow everyone who was watching by accurately lining up with the dock at a significant distance, matching rotation, and accelerating all the way in. There did not seem to be a maximum speed for docking. I could dock much, much faster than the DC, which often looked worse than a learner driver doing a reverse turn around a corner for the first time in a car with a faulty clutch. The only thing I found the it useful for was as a break to go and make a cup of tea.

I suspect that anybody who had any pretensions of becoming Elite would probably do the same.

"the then vogue for Reduced Instruction Set Computing (Risc)"

It was not just a vogue. It was necessary to push computing performance forward. If there had not been RISC architectures at the time, then I believe that computing history would have been different, and would probably not be nearly so advanced as it is now. Not that this is all to do with the ARM. MIPS, SPARC, Precision Architecture and POWER all had their parts to play in frightening the CISC manufactures into pushing performance up.

The transistor budget for the ARM 1 was, I believe, 25,000 transistors. At the same time, the 80386 had a transistor budget of 275,000. In these days of billions of transistors per die, it is easy to forget the fabrication limitations of the day.

If the ARM had been a CISC architecture, it would either not have competed with other processors in the market, or would have been too complex for a small organisation like Acorn to have been able to develop and produce. It's very existence was conditioned on it being a RISC processor.

The fact that it was a 32 bit architecture, used ridiculously low amounts of power, and still beat the pants off a 80386 processor in performance were the reason why it's descendants are still around now.

XOS was a mainframe OS

but on Xerox Sigma systems in the late '60s and early '70s. I really don't think that the article writer is likely to have used XOS.

But it is clear that there are still mainframe class systems that are not IBM compatible. Unisys have their ClearPath range using intel Xeon processors and running MCP, which is popular in US Government circles. NEC in Japan also have Itanium based mainframe classs computers running an OS called ATOS, which has evolved from GCOS (nee GECOS - which should be a familiar term to any UNIX sysadmin).

Although they are classed as mainframes, they actually have Intel processors of various types in them, and could be considered as enterprise class rack based Intel servers rather than mainframes. For anybody working on these other mainframe systems, please note I'm not quibbling, I'm just pointing out that they are different from IBM z/OS based mainframes.

Re: I had a similar idea...with a minor twist (but big data impact) -TLDR warning.

@ac 14:30 re XOR X,Y -> Z

.....except that XOR Y,Z will reconstruct X. Admittedly, whoever was wanting to retrieve X will need to know this is what you have done, and obtain both Y and Z.

XOR is just not safe unless you increase the number of keys and operation as you do in the later examples, but the more keys you have, the more chance you have that one of the storage companies go out of business, get shut down or just lose the data.

It would be better to use something like use a distributed set of symbols of Reed Solomon hashed data blocks. Doing this would enable you to reconstruct the data if one set of symbols is lost, but would make it necessary for someone to get most of the symbols in order to decode the data. The exact number of symbol sets needed, and the minimum number of sets required to decode the data would depend on the parameters in the RS encoding chosen. Each subset would not contain any usable data.

Cisco "presence" could very easily be ported to Linux or any UNIX. After all, it's available on MacOS X. All it would need is for Cisco to do the port.

The reason it is not available for Linux or UNIX is that they have decided not to do it (although I'll lay a bet on there being a skunk-works version for Linux somewhere within Cisco), rather than any technical reason.

This makes your comment rather spurious.

Re: The reason *nix based OSes don't have a problem...

I actually disagree. There is more scope for this type of event handler to affect UNIX and Linux systems, at least as long as they run a GUI that uses X11.

Part of X11 allows a suitably written program with the correct permissions (and this is NOT superuser in this case, but the user's own credential set) to re-parent a window, or indeed to insert itself anywhere in the window hierarchy. As a result, all graphic and input events destined for a window go through said program before actually being sent to the application running the window.

This allows such things as all key-press events to be captured by said program, and mouse events to be used to trigger specific actions. This is by design, and is how an X11 Window Manager works, by inserting itself between the root window and all applications. This is also how programs like xscope work.

The credentials required are such things as Magic Cookies, which for systems where the client and server programs run on the same system are often stored in protected files in the user's home directory (there are other more sophisticated methods of protection [using such things as Kerberos and SSH tunnels with SSH agent], but cryptographically signed cookies are still the most common).

This means that if a user can be persuaded to run such a program on the machine with these credentials available, they are at risk of leaking significant amounts of information. There is no requirement to become a privileged user. This is why it is important on UNIX and Linux to keep a firm control of the programs that users are allowed to run. But this often comes down to being a social engineering attack, like so many other ways of bypassing security. If you can make a user run an arbitrary program, then all bets are off regarding the security of that user, regardless of which OS they are using.

Please note that unless the cookies are leaked, this mechanism will not allow one user on a multi-user system to access another user's session on the same machine. Not that this happens very much in these days of single user Linux systems.

I don't think that many people using UNIX or Linux nowadays actually understand the way that X11 authentication works any more, and that is why the icon.

It's called "Satisfaction Guaranteed", and is in the collection "The Rest of the Robots".

Heinlein as well

He had sentient computers. I think his first was Mike (Holmes IV) in "The Moon is a Harsh Mistress", although it appears in some of his later rather bizarre crossover books as well.

Asimov did infer sexually capable robots

I can't remember for certain, but I think that it was in one of the short stories contained in the collection "The Bicentennial Man" (in the UK, it may well be in other collections as well and in the original magazine it was written for). It is inferred that a humainform robot acting as a companion to a woman was capable of sexual acts. When I get home, I'll look it up.

Windows 8: An awful lot of change for a single release

Re: @GrahamsTenPenneth

When you installed your Vista system, did it come with a driver CD? If it did, then you are comparing apples with oranges. Try using your camera or MP3 player without installing the driver. They would work about the same as on Linux, or maybe slightly worse.

I would be surprised if any modern camera or MP3 player (iPods excepted) did not configure as a storage device that would allow you to browse the media. And with an iPod (admittedly I've not tried with anything later than a 5.5G iPod Video) as long as it was first used with a Windows PC or you have the HFS+ filesystem added to your Linux system, you should still be able to browse the filesystem. Won't do you much good, however, as iPods have their own database that obfuscates the track names, making it difficult to identify the files.

If you have something like Rhythmbox or Amarok installed, there is a good chance that they will handle even the iPod database.

The fault you are blaming Linux for is actually a problem with the vendor of the media device, not Linux or the Linux community.

Re: Of Ghosts and Bathwater @ FrankAlphaXII

In this context, there is no such thing as truth, merely observed behaviours, and these are conditioned by your perspective. I don't regard you as a heretic, more like a hardened Windows user who dabbles with Linux and believes that they know how all Linux advocates think.

Even though you state that you use Fedora and KDE, yours is a very coloured view of Linux, and IMHO is out of date. If you install Fedora yourself, you will know that it is easy, and, by contrast, Windows (from scratch) is difficult. Windows drivers are hell, especially if you don't have all those shiny round driver disks that you end up needing. Much of modern Linux distributions running on modern systems works out-of-the-box.

Please examine 'ordinary' users for a while. I think that you will find that they will be running a browser, and possibly an email client. They will launch applications that would run just as well on top of any modern OS if they are available. That's about it. There is very little that most of them do (outside of the vendor application lock in) which could not be done on any modern OS (and the adoption of iOS on iPads demonstrates this).

For a majority of users, the Gnome or KDE interface (or even Unity) is all they need to launch their browser, play their media etc. It's point, select and click, and that is all they need. I admit that to get the maximum out of Linux, it may sometimes (but very rarely) be necessary to resort to a shell, but then you need to jump into the registry in Windows once in a while as well. The only thing that Windows users benefit from in Windows is familiarity, and Win8 may break this.

I mentioned the vendor application lock in. This is the real crux of the matter. If you exchange information with someone else, then the fact that MS Office is so prevalent will mean that there will be problems. And when purchasing media, it's Apple who are not interested in making an iTunes client for Linux. Same for Sky, Netflix, LoveFilm etc. It's not a Linux fault, nor should it be the communities responsibility to make up for the fact that vendors (who often have irons in the OS fire) or strict DRM requirements that will always be difficult to handle in OpenSource software, are not prepared to work in the Linux space.

But this is not a Linux problem, it's that Microsoft and other vendors have been allowed to dominate areas of the application landscape.

In the reality that I see, there is no technical reason why users cannot be trained to use any UI. There are commercial reasons, but that is not what you claim.

Android, heal thyself

Re: will be improved by users upgrading to newer versions

The whole application deployment model of Android and iOS is different from UNIX, and seriously alters the security model.

With UNIX, you have the concept of a superuser, which is responsible for the installation of applications which are then used by non-privileged users.

Android does away with the requirement to use superuser to install applications. Instead, Google have invented an application deployment framework that sits above the OS and runs as a single non-privileged user, which handles all application installation and execution, as well as making it the guardian of user data. As a result, the traditional UNIX security model is not involved.

In many cases, it is not the Android OS per-se that is compromised by the security vulnerabilities. It is the application and/or the users data. This is a fault in the execution environment (Dalvik?), not in the underlying OS.

Please don't confuse the two.

Re: Not So Smart Phones Anymore?

The only thing is that the service you are getting at the moment might get a lot more expensive if there was no advertising.

Whilst I agree that most of this is to try to maximise profits, at least some of the advertising will be helping to pay for the technology. Just think that if Google did not have healthy advertising revenues, we probably would not have Android at all. Maybe we would have had Meego or WebOS as alternatives still, but I would not want to guarantee it.

Ad funded services are annoying, but without them we would either have poorer choice or more expensive services. In some ways, this is a lose-lose scenario for consumers.

Re: I get regular calls

I get similar. My Sky HD box, which I purchased new from a well known auction site, was never under a Sky warranty, and was purchased at least five years ago. About two months ago, I got a stream of calls from more than one maintenance company wanting to sell an extended warranty because my warranty had just 'run out'. I normally verbally abuse them down the 'phone. This is not normally in my nature, but I think that someone cold-calling me with incorrect information attempting to sell me something has no right to expect not to be abused, especially as I am on the TPS. They claimed that they had obtained my information from Sky, and thus it was not a cold call. Now I understand why it was happening. I'm still unrepentant about the verbal abuse, though.

In truth, I probably could have used an extended warranty. I believe that the reason why I could by a Sky HD box at half of the then Sky HD upgrade price was because it is a first generation Thomson box that is now known to have power supply and tuner problems. I think Thomson dumped them on the open market when Sky switched manufacturer. So far, I've rebuilt the power supply twice (blown capacitors each time), and had to replace the hard disk, as well as cleaning the dust and crap out because it causes it to overheat.

According to Sky, I am now one of the last few customers using a Thomson Sky HD box, and it is causing me problems as it won't run the Anytime+ on-demand service. I think I've managed to negotiate a reasonably priced replacement direct from Sky (the free replacement period has now expired, but all they want to charge is a standard installation - even though I have a quad LNB and a Sky HD box already so installation is just plugging it in and switching the registered box on the account), but if I take it up, I'm tied to them for another year. For all it's reported problems, I wish Virgin would cable our area so we had a choice, but I suspect that will never happen now.

Re: Genius

As we appear to be in nit-picky mood at the moment, it is significantly less than half who could use the products once you take into account the pre-pubescent and post-menopausal females.

Given that a woman only menstruates for 40 years or so (Wikipedia) out of a an average life expectancy of 80 for women (stat. from the 2011 CIA yearbook again via Wikipedia), I would guess that it is no more than about 30% of the population, once you factor in the higher life expectancy of women.

He's a statistics teacher, obviously!
