Reliable system was so reliable, no one noticed its licence had expired... until it was too late

Re: Soon never seems soon enough

Indeed. One of my many jobs at work is in the charity shop arm of the business, selling stuff on eBay; we acquired an old machine that sorely needed to go to the recycler, but the c. 20 year old (!) Foxconn motherboard, complete with a 120MHz Pentium 1, was still ticking away fine. Was even Y2K compliant and accepted a date of 24 Jan 2019 without issues. We sold it for nearly £100 on eBay!

Re: It's a lose-lose situation

Windows 7 "outdated"?

Windows 7 seems to have evolved into the sweet spot for Windows OS. A bit like how all automobiles, bar a few special cases, have four wheels, a steering wheel, a shift stick or drive setting handle, and brakes.

Why change what works so well until something truly a huge step up, something that makes the pain of learning something new justifiable, becomes available?

Change for changes' sake makes no sense. The only thing obviously lacking in Windows 7 is a good touch UI for non-desktop use, but that could added on as an installable component for those who want it.

So by what objective metric is Windows 7 supposed to be outdated?

Re: How does knowing where imply knowing what?

Thanks - that took me a couple of re-reads but it helps a lot.

To save anyone else the re-reads, the key is the number 256, the number of values a byte can hold plus the memory accessed in the second step need not be protected memory.

1) Access kernel memory to put value in register.

2) Speculative execution subsystem tries to execute as if (1) was OK. It will then speculatively execute "memory access at address **in non privileged memory areas that we have legitimate access to** of which the register forms part of the resolved address (as an index/scale/whatever to a base address) that causes **one of 256** pages to be pulled into cache. It doesn't matter what data values are in these pages, nor which pages, as long as the pages are accessible to us and there are *exactly* 256 possible pages that could be accessed. It is the fact that the data values are now in cache that matters. They could be the number of fleas on your cat, number of bugs in the Pentium FPU, doesn't matter.

3) (1) faults due to privilege level. (2) Is "thrown away" as fault prevents the CPU getting to it "in the real world", **but the cache lines involved are not flushed**".

4) By using timing analysis to find out *which* page was cached, that's also the number in the register and that number was loaded from kernel memory and used in an index register of sorts **before (2) was thrown away**. Thus, you now know which number is in the address in kernel memory.

At least, that's how I read it in simple terms. Ouch!!

Martin Howe

How does knowing where imply knowing what?

Please can anyone give me a simple explanation of how knowing where data is in memory and/or whether it is currently cached or not, allows an attacker to actually access its contents if they don't have the privilege level for the memory addresses in question? Does the underlying caching mechanism *not* check bounds, privilege, etc? Does speculative execution not also do so? Bit rusty with architecture so would appreciate a simplified explanation of the one on the website - thanks.

You can help fix patent laws … now!

I hereby patent making sarcastic article titles

In today's interconnected and industrialised age, patents make as much sense as medical doctors treating sick people for evil spirits.

Problem 1 - Novelty, or rather, the lack of it. Too many ideas are easily imagined by reasonably clever people who are bombarded with information daily on the internet; the days when only a "competent practitioner of the art" could come up with something novel are for the most part gone for good. True novelty is rare.

Problem 2 - Discovery vs. Invention. Many things such as software, business processes and computer architecture are essentially mathematical abstractions and are as such discovery rather than invention. These should not be patentable in the first place.

Problem 3 - Abuse of patents. Company A buys IP for B, not to use B but to prevent it competing with product C, even if B might have been better.

Problem 4 - Prevention of composition. Patents prevent ideas being used as components. For example A=B+C. A is novel in itself, so is B but C is already patented. A never exists or gets compromised. Consider some of the early steam engines that had exactly this problem.

Problem 5 - Absolutist interpretation of IP ownership. A patent owner can charge as much as they want for a licence or even simply refuse to do so. There's no concept of knowledge being used to wider benefit to the world as a whole, at a reasonable cost.

Problem 6 - FUD. So many legal battles are about patents because it's not always clear whether a patent is valid, if it applies to a particular product, and so forth. Worse, we expect non-scientists (i.e., Judges and Juries) to decide such things!

Basically, patents are only sensible now for things that are novel AND require huge investment to make or market or distribute. E.g, drugs. Even there, there is a case that medical technology patents should be regulated, as people shouldn't die just so that others can make profit.

What I would like to see is this:

*Patents abolished for anything that does not need significant investment.

*Patents abolished for anything that is ultimately a mathematical abstraction.

*A legal right to use any idea as a component of another (cost to be arbitrated).

*No right to hold a patent unless the holder actually uses it.

*Specialist patent tribunals to arbitrate disputes over the above.

Probably not comprehensive or perfect, but it would be a starting point.

PS: Also, the concept of Prior Art to be explained to every lawyer in the world. With a 2x4 to the head. Especially those working for the USPTO :P

What should a sci-fi spaceship REALLY look like?

Spherical space ships

The Death Star. Just THE DEATH STAR. (OK it was an oblate spheroid, but close enough)

The Borg cube is very efficient in terms of volume usage, but if the DS were that shape, the audience would likely not accept it as a spaceship. (Though given how weird most stuff in SW is, who knows?)

Beeb to fund ad-mungous Local TV for local people

Martin Howe

If only it will be like local free ad papers

Free ad papers are usually local to a district or a small chunk of a county. Local TV tends to focus on a whole county or even several counties. Local TV that is as local as the free ad papers would be great; however, I can imaging it being almost impossible to fund, so it likely won't happen.

Britain takes delivery of first Nissan e-cars

Martin Howe

Why the sniping and canards?

Ever since I first read it in Elektor as a teenager, ye olde canarde about gas/coal/oil power stations rears its tired old head again. Oil, Gas and Coal will run out. A switch to renewable will be required in the future.

A generation of electric cars needs to be bedded in by that time. Having them run (ultimately) off fossil fuels in the meantime does not make pollution any worse but does facilitate it getting better in the long-term.

This is no different to refactoring a large software system under the hood so that when "The Great Event" occurs, the internal infrastructure is already in place.

Where is Judge Dredd when we need him?

Forgive my ignorance, but don't they have Law in the USA? OK, so it won't really be a helmeted jackbooted thug beating the shooter to the floor with a huge stick while shouting "TEN YEARS, CREEP!".

But surely the Police out there can at least arrest these people? Surely the Courts can sentence them to a gun ban? As I understand it, for those folks that must be worse than the Death Penalty. If they violate the ban, jail them, five years per violation. When a form of criminality becomes widespread and the Law becomes disrespected, draconian measures are the only way.

Brighton NIMBYs complain over BT broadband upgrades

Martin Howe
Welcome

I for one ...

... welcome our new green, capacious overlords. Well I would, but unfortunately they don't see our district as worth conquering :(

Many things that used to be luxuries have in the fullness of time become ubiquitous and have in practical terms evolved, more or less, into a right. Running water? Electricity? Sewerage? Telephone? 56K? Well it's arguably time for decent broadband speeds to be considered as such.

Realistically, it will require government intervention and take years for unprofitable areas to be served, but that's no excuse for telling people they should move from their loved homes to get it. Sure the cabinets shouldn't be sited insensitively, but that should apply to any street furniture.

Even with LLU we will get no more that 6Mbps, so if BT want to put a cabinet on our street, let them. Oh and it will give the cats somewhere else to sit :)

McKinnon family awaits final, final extradition decision

Martin Howe
FAIL

What has Asperger's Syndrome got to do with it anyway?

I just wish McKinnon hadn't tried to use his condition as a way of handling the case; it clouds the issue and many people are unaware of the range of effects of the condition. Perhaps it is better to first consider what would happen if he was normal.

A political activist, convinced of the existence of a Ridiculous Fantasy From The X Files Big Government Cover Up (tm), hacks into a computer system that is weakly protected, sniffs around for evidence for a smoking gun and gets caught. There is little damage caused by the act itself, but panic causes the victim to suddenly perform a lot of security work that should have been done in the first place.

In the UK (imagine he'd done it to GCHQ) we already have laws for that; it'd be worth a heavy fine and a suspended sentence or a few years in prison, depending on the severity of the offence.

Consider the arguments about (a) applying the concept of extradition before the law is updated to take account of new technology, (b) failing to fall back on appropriate UK law in light of that, (c) exaggerating an unextraditable and relatively less serious offence into an extraditable and serious crime for the sake of national pride, (d) exaggerating estimates of damage caused by the criminal act (see (c)), (e) differences in prison regimes and sentencing, (f) and this is the **only** relevance of Asperger's Syndrome, how well the legal system in the imprisoning country prevents disabled criminals from being abused by other convicts during incarceration.

While worth examining in themselves, they all miss the fundamental problem: the **retro-active** use of a **new** agreement, thus contravening the spirit of one of the holiest and most sacred principles of UK law.

For any government to break one of a country's most sacred legal principles for the sake of expediency is a truly terrifying act, since it seriously compromises the Rule of Law and means that potentially "none of us are safe". Accordingly, it is something that can be considered **only in the most extreme circumstances**, for example the 1946 war crimes trials and suchlike.

McKinnon's crime was nowhere near on a par with genocide or institutionalised child abuse; accordingly, his extradition should be prohibited by legal principle alone. Having said that, he shouldn't get away with it, so we should just use the Computer Misuse Act and have done with it.

Nowadays, the big three remind me of the closing lines of Animal Farm... pigs desperate to stay at the trough and who look much the same, coached in "persona" for fear of being seen as extreme and scaring off the voters.

Anyway Cheryl Cole is a convicted thug and for me average looking at best. If we're talking girl bands - Sarah Harding (yummy for a blonde) or Frankie Sandford. Page 3 girls - Peta Todd or Vikki Blows. Actors - Caroline Catz or Clare Holman. Even Megan Fox if I really must. But Cheryl need not apply.
