Old-ish terminology?

A little outdated surely? "true-ish" has been deprecated in favour of the 2.0 term, "truthiness"

Visa gives merchants crypto card security guidelines

Andy Dingley
Boffin

Encryption - just encourages the wrong approach

Encryption can itself be one of the worst enemies here.

Post-authorisation, very few sites need to encrypt the card number. It's not even necesary to store the thing! The attitude of "we can store it, it's OK, we've encrypted it" is a fallacy shared by a huge number of sites, operators and even major players who Ought To Know Better (and are indeed told so in PCI DSS). It's a shift from "we don't need to do this" to "we need to do this competently, forever, against attack" and we know how hard that is.

If you want an audit trail, _obfuscate_ the number (wipe all but the last digits), don't encrypt it. That's just not reversible, even if the whole database is compromised. Works fine for audit trails and answering customer post facto denials too.

If the card number does need to be held long-term (future repeat charges), then that's a whole different business, not the usual one-off web shopping visit. Do it if and when it's needed, but that's the rare exception on most sites, not the rule.

As for encryption with a symmetric key cipher (and just how nearby is that encryption key held?), that's a WTF of its own.

Demon splurges details of 3,600 customers in billing email

Andy Dingley
Paris Hilton

Demon is so last century

The question isn't even why anyone is still with Demon: for some years now it has been why you're still with Nildram, to where you'd moved after the first mass migration away from Demon when Thus first got involved. As seems sadly inevitable, that bolthole went downhill too and it was time to abandon it in turn.

(Andrews & Arnold are lovely though)

Paris, because it's who Cliff would have chosen

Wacky Jacqui Smith says whole country crusading against CCTV

Andy Dingley

Not the first careless phrasing from Jacqui Smith

This is also the Home Sec who supported Tasers for the police as being a better alternative than firearms.

Of course under UK law, a Taser _is_ a firearm, else we'd be allowed them too. Unless of course this pronouncement means that we're no longer classifying electricity as a "noxious fluid", and thus using it as a firearm.

Ares I manned rocket section explodes in testing

Andy Dingley

How to shut off a solid rocket motor

Solid motors (the Shuttle SRBs at least) do have some capability to be switched off in flight. The burn rate of these propellants is strongly dependent on internal pressure. Opening a large vent port (once only, with explosives) at the top of the booster drops the pressure and reduces burn rate to a crawl. This is already done on the Shuttle when the SRBs are jettisioned.

It makes little difference to Ares (I've no idea if such a system is even fitted), but it's a workable bit of rocket motor technology.

Isn't Lewis supposed to be ex-mil?

I thought he'd appreciate the difference between a self-forging fragment and a simple Monroe effect shaped charge.

But then again, "Black Arrow", 'nuff said

The HTML that says no - Joi Ito's pitch for a theft-free web

Andy Dingley

DRM that assumes the decency of the majority

"...astonishing that a grown adult could..."

Maybe Creative Commons needs to go back to its roots: a teenager and a Stanford law professor, and no-one able to tell who was the smarter of the two.

Of course this is DRM. If you like it, it's Marxist DRM - it assumes that people are basically good and honest, and if you advise them simply as to what's OK and what isn't, then most of them _will_ behave themselves.

This only fails when you meet the deliberate pirates or the naive (or el Reg a couple of days ago, with the CC-licensed but uncredited Mac photo) as technical DRM regularly fails here anyway; you're still falling back to enforcement and working back from who's selling the Mama Mia DVDs at the car boot sale. That doesn't invalidate Ito's call for client-side examination and notification of bundled licences.

What's with the CC-by-sa on the image?

The SE/30 image is tagged as "Creative Commons Attribution ShareAlike 2.5 License."

So where's the attribution? You've used someone's copyright image, how about complying with the licence under which they allowed you to do so and crediting them for it.

Vote now for your worst net neologism

Andy Dingley

Bad neologisms or bad topics?

Most of the votes so far seem to dislike "2.0" etc. and to give "ZOMFG" and the like an easier ride.

Agreed that the content of 2.0 might be the biggest pile of powerpoint-flavoured dysonist crapwank and badgers' paws ever, but as a _neologism_ to refer to the topic, it's not bad. Equally "edutainment" and "webinar".

Now WTF is WTF? Why is ROFL funny? These are just the crude linguistic shorthands of dullards.

Would Stephen Fry ever ask us to downcast the podload of his mashup? I believe so (should he ever wish to inflict such a thing on the blogosphere)

Would the esteemed Fry respond to Alan Davies' witticism with a ROFL? I think not.

UK bank chief stung in ID theft scam

John Munden

"interviewed by his bank manager"?

This is HBOS, as in "Halifax". How about him serving some real prison time for being a victim of fraud? After all, it was good enough for John Munden

Dead author's estate snatches child's domain

Andy Dingley

Who forces Narnia on their kids?

"so that their son could have a Narnia-related email address."

That's not just bad faith, that's Cruel and Unusual. No matter how much money and CGI Hollywood throws at these things, CS Lewis is always going to be the naffest "improving" literature ever foisted upon suffering, embarassed kids.

Did LotR have to be made out of order, cherry-picking the least feeble of the tales first? No.

Mind, if they make "The Silver Chair", Puddleglum might sell to the emo-kid market.

Prius hybrid to get rooftop solar panel

Andy Dingley
Thumb Up

Cooling alone is worth having

It's a great idea. A big market for the Prius is So Cal (partly due to local pre-EV regulations), where temperature rise when parked is a serious ergonomic problem. This solar panel might do little for driving the car, but if it means the car can keep itself circulating air (and thus cooler) when parked without flattening the traction battery, then that's worth it on its own. Such cooling is well-established on boats, and AFAIR Saab did it a while back too.

As to overall efficiency, then the Prius is a brilliant way to make an urban taxi. It's _not_ a super-efficient motorway cruiser (and not claimed to be one), but i's a damned clever hybrid.
