Protected names

Kal-El might be a bit of a problem, but I can't imagine that the same would be true about Wayne, Logan or Stark. After all, Logan and Stark have other meanings, and if DC can prevent Wayne being used, then Mr Roonie and probably Harry Enfield would also have to look out.

IPCC chief: ANPR is 'a victim of its own success'

200 bytes?

Ignoring an image, why 200 bytes? Surely, Camera location, <=4 bytes (4 billion locations should be sufficient across the UK), number plate <=7 for UK plates (let's be generous and allow 10), and a timestamp, again let's be generous and allow 8 bytes (UNIX per-second timestamps can still be represented by 4 bytes until 2036).

Total, 22 bytes per record, maybe with some overhead.

Multiply by your 350 million records a day (I'm not sure if this is actually accurate, as not every vehicle is driven every day, and I want to be shown the 10 ANPR cameras a day that I pass), and you still only come up with around 10GB a day. Deem that data useless after 6 months, and you're talking about 2TB, or one current generation high end Sata disk in total.

The recorded image is only necessary if you intend to use record for enforcement (for say, driving without road tax, MOT, or insurance), but probably not for locating people by spotting their cars. If you had automatic discard of images of vehicles that were legal and not on a hit-list, then you would not need to keep all of the images anyway.

Bearing in mind that many more times that volume of data is transmitted and stored daily in any number of data applications, it does not seem too far fetched after all.

BTW. I wish to state that I do not condone this information being kept and used for tracking purposes at all. I don't mind to get illegal cars/drivers off the road, but that's it as far as I am concerned.

I agree that would be clearer, but you cannot be convicted without being charged, and it is an OR between the two, so IMHO it should be clear enough. Mind you, grammar was never my strongest subject.

Adobe Flash: 20m phones flip Steve Jobs the bird

@cameron

If I read it correctly, the MPEG-LA consortium are wanting H.264 decoders in the silicon, so that to play it, you do some setup (window size and position etc.) and then just throw the encoded byte stream directly at the hardware. Almost zero CPU usage.

If this is the case, you may be able to use some of the other accelerated features for WebM, but not the direct decoding.

Again, I am happy to be corrected by someone with more knowledge.

It means exactly what it says

using the graphic hardware for operations that you would otherwise have to use the CPU for. This includes things like, but not limited to, scaling, texture fill, pixmap copying, shading, and may go up as far as complex rendering such as hidden object removal, surface mapping, and shadow and light-source calculation. Of course, much of this is unnecessary for Flashplayer, and having a hardware H.264 decoder built into the graphics hardware is probably what MPEG-LA and it's members (including Apple) are talking about.

What Adobe may be doing is adding direct support for certain mobile graphic chipsets directly in Flash. They can do this without the graphics hardware vendors direct support if the graphics API is well enough documented. Of course, documenting such things to sufficient detail is entirely foreign to some companies.

In the PC world, much of this is not really necessary because you have abstraction layers like DirectX or OpenGL with hardware vendor support, and can have hardware accelerated graphics while only writing to one or two well-known API's. As far as I am aware, there is no such abstraction for any of the mobile platforms, but I would be happy for someone to correct me if that is not the case.

Microsoft's IE9: Don't believe the hype

Peter Gathercole
Silver badge
Thumb Down

@Doug 11

Microsoft want to make IE a lever to sell Windows. As such, they need to differentiate it from Firefox, Chrome, Safari and Opera.

Unfortunately, with previous versions of IE, it appeared that their model was to make it significantly non-standards compliant but push it to become a de-facto standard so people who wanted a 'full' internet experience would be inconvenienced by the other browsers. Add a dependency between the browser and new versions of Windows (i.e. can't run IE9 on WinXP), and hey presto, you've made it so people with totally usable PC's need to upgrade to the new OS to use the 'features', adding to MS's coffers in the process.

They need to learn that this will no longer happen and indeed may backfire, so unless they embrace the standards, they will rapidly loose that lever, and will have to rely on other tactics in order to push Windows. I believe that they think that HTML5 including the H.264 codec protected by patents will be the enabler to bind people to Windows for another round of PC purchases.

Re: WINE ?

Yes, but they will not be running IE9 as AFAIK, there is no Vista or Win7 persona for Wine yet. What I've read appears to suggest that MS have made sufficient changes in the last two versions of Windows to require significant work from the Wine community to make it compatible.

Nokia Digital Radio Headset DAB

Peter Gathercole
Silver badge

You beat me to it

I was going to say exactly the same. Sadly, my iPod died, so my Rovi is currently sitting on a shelf unloved while I listen to music and FM radio on my Android phone.

I'll take issue with the review, however. Quote - "Indeed, the more robust signal you tend to get on the move also makes up for any step down in sound quality" - Where the hell did you test this?

Whenever I try to listen on the move, the dropout rate and the bubbling mud problem from varying signal strength makes DAB impossible to listen to, especially for spoken word programmes. Try listening to a comedy show when you keep missing the punch-lines. I know I live out in the sticks, but I also have this problem travelling down the M5 within 10 miles of a major city with a correctly installed DAB radio specifically made for a car.

With FM, you get a hiss or maybe some distorted output, but you can follow a conversation. Try doing that when you completely loose the channel for seconds at a time.

Don't get me wrong. I'm all for Digital Radio, and have five in total in the house and car, but until the transmitter power levels increase, I'll be listening to FM on the move.

BTW swisstoni. The delay is caused by the time it takes to digitise the audio at source and decode in your receiver. It's never going to go away regardless of what anybody tries to do. You could try buying a more expensive receiver, but there is no guaranteeing that it will have a faster processor in it, and would only address the decoding side. I'm afraid you will just have to learn to live with it.

Subdued RM says government cuts challenge its business

Peter Gathercole
Silver badge

Never convinced about RM

Many, many years ago I justified and built a computer resource for teaching what was called Computer Appreciation around BBC micros, ECOnet and Acorn file servers in a UK Polytechnic. I managed to get so much for the budget, including colour monitors, robot arms, digitizer tablets, touch screens, printers, plotters, speech recognition and synthesizers, teletext decoders, video cameras, mice, lightpens, and a basic CAD systems (remember, at the time, an Apple ][ with a Bitstick was considered good). We also had representative word processor, spreadsheet and database products and a good Basic (natch) as well as Acornsoft Pascal. This was to teach people from all learning disciplines, not just computing students, what computers could do in the early 1980's before DOS/Windows PC's had achieved dominance, and also before people had Home computers.

The main Computer Unit poured scorn on our efforts, because they wanted to put in RM 480Z's backed up by a 380Z as a file server. Equipping the lab with what they suggested would have blown the whole budget on the computer hardware without being able to afford any of the peripherals, demonstrating that their systems were overpriced. And I don't believe that it could have been used for half of what we actually used it for.

I was very sad to see Acorn loose out in the education sector, especially when RM moved to MS-DOS based systems. The 80186 based Nimbus 1's were neither cheap, standard, or IBM PC compatible.

I just looked at their web site, and saw a device for mobile data capture, priced "from £3.75". I thought "Wow, that looks interesting and cheap. Maybe RM have learned". I then looked further. £3.75 apparently buys you an extension cable (basically a 3m M-F 15 pin serial cable from what I can see).

The actual device itself costs £170, plus £19 for the software (you would have thought they could have included that, bearing in mind that it is essential to use with a computer), and all of the more interesting additional sensors cost £50-80. Suddenly I'm not interested.

I'm glad I'm not working in education any more. The thought of hearding rooms-full of PC's would fill me with dread.

SCO: 'Someone wants to buy our software biz!'

Peter Gathercole
Silver badge
Alert

Because....

SCO keep telling the bankruptcy court that if they are allowed to continue their claim against IBM, and win, that they will have enough money to settle the money they owe.

Unless someone convinces said court that the claims are fatuous, and will never be more than a way of paying lawyers, then the court *HAS* to listen, because they have a duty to recover as much value as possible for the creditors.

And although there have been rulings on the admissibility of the evidence and who owns the copyright, the original case is still outstanding. There may still be a small chance that there is a case against IBM because not all of the documents are in the public domain, but even if there is, it is unlikely that SCO would actually be able to collect any of the money.

I keep feeling that the case against IBM has to reach court and be finally ruled on, so that this whole mess can be consigned to the history books.

What worries me is that Novell are the ones who objected last time this UnXis tried to by the assets, but Novell is not the company it was. Microsoft had a finger in the pie when Attachmate bought Novell. If Microsoft had some way of suggesting to Attachmate that MS would pay more for the IP they bought in the deal if Attachmate/Novell would not object this time round, the whole circus could start anew (shudder).

Microsoft finally says adios to Autorun

Peter Gathercole
Silver badge
WTF?

It was used very often

to kick off a software installer. Even people like PCW used to use it for their cover-mounted CD and DVD's.

I've installed a recent HP printer, and it used autorun (the installation instructions did document how to run it without auto run, but it was phrased like "If the installer program doesn't automatically start, open the CD, and .....").

My significant other (worded to attempt to not to upset the Moderatorix) has some craft software that needs the CD inserted explicitly in the D: drive (and heaven forbid if your CD is not the D: drive), and the instructions for this expect autorun to work, and do not contain an alternative. I keep explaining this, and she keeps telling me that her computer is broken because the software does not start. Grrrrrrrr.

I think too many of the people commenting here are in the Windows support business, where they are in control of any software installation, and do not talk to home and SOHO businesses where simplicity and hand-holding is essential for people who just use computers as tools.

I can't be so old that this has passed out of memory, can I?

DEC founder Ken Olsen is dead

Peter Gathercole
Silver badge

What I liked

was that the Program Counter was basically register 8, and that many of the jump, load immediate and return instructions were just special cases of other load and store instructions that you would use on other registers.

At one time, I used to be able to dis-assemble PDP-11 machine code without the book. It really was just such a regular instruction set that it was easy.

It used to be interesting to see just how C mapped into PDP-11 machine code. Often, like the case Keris quotes, a simple instruction like i++; would map into a single instruction.

Another innovation in reasonably priced computers that I believe was championed (although not invented) by DEC was the segmented address space that was implemented in such a way as to make it non-intrusive to the program writer, but also would allow different processes to have their own virtual address space independent from the physical memory addressing. It was this feature more than anything else that allowed multi-user computers to be created that allowed a user to screw up their own program without affecting the OS or other user's programs.

Although it was known as a PDP-10

they were labelled as DEC System 10 (and the followup, DEC system 20) running TOPS-10 and TOPS-20 as the OS. Real DEC sysprogs called them things like KI and KL systems, after their processor types.

IIRC, they were a bit quirky, having a 36 bit word length, but introduced the concept of a cluster with a fast interconnect. They had a thing called the CI bus, which was like an extended MASBUS that allowed you to connect systems together, as well as to Hierarchical Storage Controllers (HSC's) which provided shared disk between the systems.

This was adapted to become the BI bus for VAXen, which paved the way for VAXCluster.

Pedantic mode on

Sky 1 was the flying part of Skydiver 1 (there was more than one Skydiver - there are references to Skydiver 3). The Sky part was the plane, and that only had one crew member, the pilot, who was always the Captain.

The women on the -diver part did also wear string vests, but had substantial under-garments underneath. Not nearly as interesting as the Moonbase uniforms.

BTW. The televised version (at least the more recent ITV 4 screenings) of UFO Episode 1 had several scenes cut out when compared to the DVD, which included the conversion of Grabrelle Drake's duty jumpsuit to the mini-skirt recreational garb (while she was wearing it, mind).

IMHO, UFO was originally targeted as a series for adults, not children, and some of the episodes were originally never broadcast in day/early evening slots, but later in the evening. It was only the association of Gerry Anderson with puppet shows that made the ITV companies play it in the same slots as Stingray/Thunderbirds/Captain Scarlet (normally just before World of Sport on a Saturday morning, or at least that is when LWT and Southern Television played them).

This adult target explains why it was a much darker series than previous Anderson shows, and contained several episodes that I regard as not suitable for children at all. Definitely set me on the edge of my seat at the age of 9.

That's uncanny, although form-follows-function makes it inevitable

I used to watch the Tomorrow People as one of my favourite shows.

They did not need 3G or any cellular technology, because they had an alien mentor from a more advanced planet (the Trig) who provided access to a limited amount of advanced technology to augment the still developing telepathic abilities of the group. They regularly used remote data gathering and communication devices, so this proto-ipad probably did not need 3G, and may have used a near-field technology, as it was only used in their lab.

In addition, they had an advanced AI called TIM who coordinated all of the technology, although it was not portrayed as techno-magic, and there were definite limits to what they could do.

On a related note, was Captain Kirk in ST-TOS not forever using a device, often given to him by Yeoman Rand (gotta love those uniforms) not an electronic device? I know it used a stylus, so was probably more like a Newton than an iPad, but still.

Super-thin materials could POWER our WORLD

Peter Gathercole
Silver badge

Yes, planar

Graphine is a case of a planar crystalline structure I admit (I did mention planar form), but it is a special case, being just carbon with no other elements present. Looking up molybdenum disulphide (MoS2), and bismuth telluride (Bi2Te3) appear to me to show structures that do not have all of the atoms in the molecule arranged in a plane, especially when in crystalline form.

Of course, it may be that the boffins have found another way to form the crystals so that all of the atoms line up in a plane.

α-BN form Boron nitride looks interesting, though.

Atoms?

Quote: "Oxford and Dublin boffins have unlocked a doorway leading to more than 150 super-thin exotic nanosheet materials just one atom thick" and "boron nitride (BN), molybdenum disulphide (MoS2), and bismuth telluride (Bi2Te3)"

As these are not pure elements that are being talked about, surely they should be one *molecule* thick, not one *atom* thick, even if they are arranged in a totally planar fashion.

You would think that the "boffins" would know better. Or maybe they are really just "scientists"!

Palm Treo's were able to surf the Internet years before either iPhone or Blackberrys were available. And although there was not an app store as such, it was possible to download free and paid applications directly to the phone.

3rd party add-ons also gave WiFi connectivity, although some of the non-phone Palm devices had it built in. And there were media and productivity apps available, and they were touch-screen devices.

Microsoft reinfects Chrome with closed video codec

Peter Gathercole

Stop

@Surprised, I'm not

The decoder license is only part of the picture. Look at the MPEG-LA license with regard to using the coder part for commercial content. There is a fee payment due on each item encoded for commercial use, and IIRC, it's not pennies.

I'm fairly certain that things like TV-on-demand, adverts, commercial presentations, pornography and even free videos on an ad-supported site (think Facebook and YouTube) can be considered as a commercial use, so there is much money to be extracted from content providers. In order for the providers to consider H.264 over a free codec, they have to see almost a clean sheet of browsers supporting it at no cost to the end users. Otherwise they will not see it as an expense worth paying.

It is interesting that WinXP is being avoided. Probably trying to provide more leverage to get end users to fork out for another Windows license.

I would love to see a system for recycling transferable XP Retail licenses from scrapped systems, rather than them disappearing into the smelter with the system case. Anybody any ideas about setting something like this up before they all disappear?

Sky loses pub footy case

Peter Gathercole

@lou

It all depends on the satellite. There are several different satellite systems in geo-synchronous orbit including Astra, Eurobird, Hotbird, Eutelsat amongst many others. Not all of their transmission footprints are the same, and some are better in southern Europe, and some in north/north west. For example, most of the working Astra 1 and 2 satellites cover most of northern Europe, but not southern Italy or Greece. Chances are the pub was using one of the other satellites which cover southern Europe, some of which are nor encrypted and can be picked up using equipment with the right dish, even though it is not intended for a particular region.

It really is an issue with the content provider and the broadcasting company, as has been pointed out in other comments. Sky cannot prevent someone buying equipment to point at an out-of-region marginal satellite, even if it does overlap with their paid-for service.

The cost of not deduping

Peter Gathercole
Silver badge

There is a trust issue in the examples in the article

"electronic copies of their HR contract and pension scheme guide"

If there were just a single copy of this type of information, then employees would have trouble making sure that what they agreed with when they started a job was the same as the current single copy. You would end up with needing an audit trail for changes to your single copy, with it's own complexity and storage issues. People keep their own copies as a point-in-time reference, to guard against change in the primary copy.

It's funny. Lotus Notes, which was originally sold as a document management system, was selling this "store a pointer, not the document" 15 or more years ago. This aspect of it's use has fallen by the wayside, but I'm sure that it is still in there somewhere. Mind you, using Notes as the glue for a mobile workforce (as IBM does) requires multiple copies to be stored in the hard disk of all of the laptops anyway, so the de-duplication benefits are negated.

Another thing is that you don't want to de-dupe your backup, at least not completely. You must have multiple copies on different media, because media fails. Enterprise backup tools such as TSM work using an incremental-forever model, meaning that by default, only one copy of each version of a file is backed up, but then has specific techniques to force more than one copy of a file to be kept on separate media.

I know I am a born sceptic, but I must admit to being unconvinced by the block-level de-duplication that is being pushed by vendors. Maybe I have just not seen the right studies, or maybe I'm already de-duplicating a lot of what I do using techniques like incremental-forever backups and single-system image deployment.

Maybe I'm just a neo-luddite. Who knows.

India's cheap-as-chips delayed by cash spat

Peter Gathercole
Silver badge

£20 does seem a bit optimistic

but if you can build a basic mobile phone, with rechargeable battery screen and keyboard, and sell it (presumably with some profit) in the UK for under £30 (as seen at http://www.reghardware.com/2010/12/03/ten_essential_cheap_voice_phones/), then why should you think that it was impossible. Also look at the 7" Android epad and apad devices that are selling on ebay presumably at a profit to the supply chain for less than £80 at the moment.

I know that the phone companies probably make a bit of a loss on the phones, hoping to recoup it from the phone charges, but I cannot believe they subsidise it by a significant amount.

I doubt that the Indian government is going to insist on a device capable of running Windows 7 with 3D high performance graphics, a multi-megapixel display and a terabyte hard disk, and they will probably drive the profit element down as far as possible. If they are assembled in India, they may also be able to fudge or hide the labour costs, in the same way that they subsidise the railways.

What do you actually need for basic web surfing, email and a bit of text processing? Probably a <500MHz ARM, 256MB memory, 2GB backing store, a basic keyboard and mouse (assuming you are not going to use a touch screen) and a display of 640x480 or so. If the web surfing is intended to be government information (voting, census, tax etc) then they can control the web content and thus the requirements of the display.

So impossible at £30, maybe not.

Bot attacks Linux and Mac but can't lock down its booty

Silver badge

...and more

There are many more places than just the .bashrc (assuming you're using bash, of course, I prefer the AT&T software toolbox ksh myself). Both KDE and Gnome (and most other X11 Window mangers as well) have user startup directories and rc files to allow attacks on systems accessed with a GUI, and you would, of course, have the normal PATH and LD_LIBRARY_PATH attack vectors that could be used to subvert commands that people use all the time, and there are many more.

Linux is not immune from attack, it's just that an attack needs to do more things to really pwn it . For instance, if a user has iptables configured to control inbound and outbound traffic on a Linux system (assuming that the user does not run everything as root), you would have to engage in tricking the user to sudo a command, or otherwise obtain escalated privileges to alter the configuration or turn it off, unlike most windows systems.

There is no such thing as a totally secure OS, it's just more difficult to mess with Linux.

The OSX statistics in the article are a surprise, however.

Flash on Linux

I know that this is not a help forum, but I recently found out something revealing wrt flash in Firefox on Linux.

I was puzzled by the fact that on the same hardware, flash appeared to run much faster on a new Ubuntu install than on a system that had been upgraded. The same was true on a new install using a previous home filesystem.

I found out that there appears to be a firefox quirk left over from a previous way of installing flash, which ended up installing a shared object called libflashplayer.so in the ~/.mozilla/plugins directory, which over-rides the version of flash installed system wide. This meant that even though I had flash 10.something installed, the properties shown in a flash window showed 9.something. I even found that renaming the file to libflashplayer.so.save in the plugins directory still caused it to be picked up.

This screwed up BBC iplayer and many other sites that checked the version of Flash installed. This had puzzled me for a long time.

Deleting the file completely suddenly made flash work sooooo much better. My daily use system is a Thinkpad T30 2GHz Mobile Pentium 4 running Hardy Heron at the moment (I'm still having problems with KMS, suspend and ATI 7500 mobility graphics adapter on Lucid, and I only want to use LTS releases), and even this is able to make a passable attempt at most YouTube videos now.

I have another dual core Pentium E2200 system, which I think is clocked at 2.2GHz running Lucid Lynx, and that manages flash fullscreen without problems after similar treatment.

I think that everybody who experiences slow flash in Firefox may want to check whether they have something similar.

It is quite clear in the Sky agreement. You do indeed own the box once you have passed the 1 year initial agreement. But without a Sky subscription, no matter which box you have, all you can do with it is watch free-to-air channels as they are broadcast in standard definition (with the possible exception of the HD BBC channels).

I recently had my Sky subscription dropped because my bank had cancelled the direct debit (long story), and I could not see Sky 1, Sky 2, Living, Sky movies or even Dave (which is available free-to-air), or any of the kids or documentary channels. Can't remember if the BBC HD channels worked. Just what you would get if you took the Sky card out (although the message on the encrypted channels was a bit more polite). What's even worse, I could not see anything stored on the hard-disk, even if it was from a Free-To-Air channel.

This makes the Sky HD box useless as a recorder without a subscription, even for FTA channels.

What is more interesting, as part of any 'upgrade' the Sky installer will probably want to take YOUR old box away. I'm not sure if this is in the upgrade agreement or not (I've not done one, I got my Sky HD box off ebay). This means that if you later want Sky Multiroom, you end up paying for another Sky box to replace the one you previously had!

I'm wondering whether we could challenge whether Sky have the right to restrict the recording function for FTA channels on Sky+ boxes without a Sky subscription? Anybody any thoughts?

I recently had a requirement to read some 'spinning rust' from systems I ran in the same time frame (one was a 1.1GB Quantum disk, another was a ~860MB Seagate disk), and the data was still there, still readable.

I have, however, found that older media, particularly floppies (5.25 and 3.5) from the same period or older are very much more a problem, with an almost 50% failure rate of those that I tried (including a whole set of precious and irreplaceable BBC micro disks).

I worry about how long an archived MLC or even SLC flash drive will remain be readable after being put on the shelf. I have already had various flash cards fail on me, which is not a problem for cards used for transient information (holding photos until they are loaded onto a computer, or copies of ripped music or video that is also held elsewhere). Throw them away, and buy another one, reload the data if applicable.

But this would be more of a problem if flash was being used as the primary repository of the information.

I'm not sure that disk is the correct solution either (especially as old style SCSI is pretty much dead, and EIDE interfaces disappear from new systems, replaced by SATA, and SAS and other serial technologies), but I predict that it will be more useful for archive storage than Flash memory. I'm purposefully ignoring tape, as this is now far too expensive for ordinary people, even though the remaining tape and drive manufacturers have a roadmap for data longevity.

Looks like we are fated to continue to re-write our important data forever as we move away from media with any significant lifetime. I think we will look back to days when books were on paper, photographs were on film, and music was on vinyl, all with a lifetime measured in decades, with some nostalgia.

Intel touts 'Sandy Bridge' video chops

@Matt

I know that you wouldn't necessarily put one of these in every system, I was wondering if the encryption keys are in the Sandy Bridge processor, and the keys were mandated by the content provider's encryption, how would you use another processor/graphics card combo.

It's probably not actually going to happen, I was seeing whether anybody would bite to start a discussion.

Intel Insider?

So the processor will run a service to allow streaming of video content without the OS being involved? Because this is what the article appears to say!

I think that this is more likely to be media encryption keys locked in the processor, so those nasty Open Source people can't hack them to allow the content to be 'stolen' while it passes through the OS layers. This would enable the media to be encrypted all the way from the server on the Internet to the graphics hardware, and thence on to the display device. Sounds like Intel and the content providers got tired of waiting for the TCG to deliver bare-metal-to-application system trust, so have bypassed the whole OS stack, and large parts of the system hardware.

This does pose the question what if you want to use better graphics hardware than Intel provide? Still, I'm just speculating here.

Who will rid me of these obsolete PCs?

Unexpected results

I'll try to dig out a reference, but in the last year, one of the UK magazines (or it might have been the UK PC World online magazine) did some testing and found that putting overspec'd power supplies in systems actually reduced the power consumption. So, if you had a system requiring 450W, putting in an 800W power supply resulted in less power used than a 500W power supply in the same system. They published the measured consumption figures, and these showed a considerable difference.

It was reasoned that a power supply is most efficient towards the middle of it's rated capacity, and efficiency falls off as you reach the limit. In addition, the power supply is more likely to continue to cope even as it ages.

I measure that my 24x7 firewall, which is currently a AMD K6-II (remember those?) clocked at 550MHz only consumes about 85W measured with an in-line consumption meter, so older kit really does consume less and could be less than a 100W filament light bulb (and my 2GHz P4 T30 Thinkpad only uses about 45W even when charging at the same time as it is running). My kids recent gaming rigs draw more like 500W, though.

Don't think I would like to use the K6 system as my workstation, however.

I can only comment on the UK

and this inverse exponential is how I was told to run the residual value of my asset register by two different accountants.

Only in an LLU area

If I were to switch to SKY broadband, even though I would qualify due to my package, it is not available where I live. I can buy the paid service from SKY, but this is delivered using BT Wholesale just like every other provider in the area.

Windows license

You also have very restrictive conditions on the Windows license. Unless you can pass on all the documentation and original media, the Windows EULA does not allow you to transfer the Windows license. And what good to lower-income households are computers without Windows (yes, I am a Linux advocate, but I am realistic enough to know that most people currently don't want Linux, unfortunately).

I'm sure that this is often conveniently overlooked, but any organization involved in re-deploying old systems will not risk crossing Microsoft and their lawyers, and will avoid most old kit unless they are putting Linux on it.

Small biz calls for end date on enhanced 17.5% VAT

@JimC, it's not quite on profit, but Value Add

You've pretty much repeated what I said, but at no point is it actually related to any profit (in the tax sense) you might make. VAT is related to sales and purchases which I do admit is INDIRECTLY related to profits. In any case, your VAT registered entity is not paying, their customers are, and you are acting as the tax collector.

If you have ever filled in a VAT form, the calculation goes (this is simplified, because I am not considering cross-border VAT) as follows:

Net VAT=VAT charged on sales minus VAT paid on purchases

They also want to know your gross sales for the period and the value of any purchases, but these do not take any part in the calculation, they're just there to allow some form of sanity and fraud checking.

It's that simple, and if you think it through, you as an entity registered for VAT are not paying any VAT at all on your purchases as you offset it against the VAT you charge (it's offset at the point of paying it to HMRC, not actually paid and claimed back). Your customers (who might also be VAT registered and passing it on) are paying it to you, and this re-curses down until you reach someone who is NOT VAT registered, and they end up actually paying without any way of offsetting it.

When I was involved in running a company, I regarded it as a financially neutral operation, although I did begrudge the paperwork. The only thing that was not neutral is that if you paid your VAT quarterly, you could stuff the money in an interest generating account until you needed it to pay it to HMRC.

The point I was trying to make is that you don't actually have to be a very big business to have to be registered for VAT, and if you are, it is neutral to you, although not to your customers. £50,000 might appear a lot, but if you have four staff being paid full time at national minimum wage, then you must be a good way to the threshold in order to be able to pay them. Any form of shop or pub almost certainly has more than £50,000 annual turnover, as this equates to less than £1,000 per week.

As a result, your competitors are probably also registered for VAT, and in the same boat. It's only if you are competing against someone VERY small (under £50,000 PA turnover) that you will be at a disadvantage.

Only affects very small businesses

probably with a turnover of £50,000 or less. Over that amount, businesses have to register for VAT, and charge it on their services, and are allowed to claim back the VAT they pay on any business purchases against what they collect (yes, businesses acting as tax collectors for the government).

The only thing it will do, however, is make their prices higher, as they will have to increase the amount of VAT they charge, but this will also be the same for their competitors. It will also force them to update the processes they use to work out the VAT. This should not be too hard, as they have had practice at changing the VAT rate for the last two years.

The FSB do a good job on the behalf of small businesses, but this time I believe that they are saying something just so that they are not silent on the matter.

Garmin tells iPhone users where to go

May be free

but if I could have got updates (which are not available any more, having been dropped as a supported device), I would prefer to use TomTom Navigator 6 that I had running on my Palm Treo 650 using an external bluetooth GPS device than use Google Navigator on my Samsung Galaxy (the Treo really was a smartphone in it's time)

The problem is that the Google app does not provide enough information with regard to speed, time to destination and distance to destination. All I appear to get is time to destination and distance to the next change in navigation (i.e. junction), and even this appears quite arbitrary when in the country.

For instance, on the A396, there is a tight left turn in Exebridge which is counted as a change in navigation, so I can tell how far it is to that even though it is the same road, rather than when I reach the end of the A396. Not clever. And I still find it annoying that it calls the road things like the "A three thousand three hundred and ninety one", rather than a-three-three-nine-one. Reading the street names is clever, though.

I also miss setting the journey up in advance, rather than getting in the car and waiting for it to work out where it is before entering the destination. One time I was in the outskirts of a city, and had to detour due to a closed road, and it did not re-plan the route until I had managed to nearly get to my destination.

Never mind, hopefully Google will update it sometime to make it more usable.

Ford cars get draconian parental controls

Ford Popular

The follow on vehicle was a 650cc Ford Angular - sorry, Anglia, immortalised by being one of the first Police PANDA cars.

This could not go much above 60 either, and radio's were really a luxury add-on, as was sound-proofing of the engine compartment.

My first car was a second or third hand top-of-the-range 1976 Vauxhall shove-it - sorry, Chevette GLS which had semi-alloy wheels (steel rims, alloy centres), wide(r) tyres, velour seats, sound-proofing, body styling trim and (shock) a heated rear window all as standard, but no radio. A decent stereo radio-cassette was one of the first things I fitted, though, even though I had to dismantle half of the dashboard to get it in and drill a hole for the aerial in the wing.

It would do 80 downhill with a following wind, though!
