Fake broadband ISP support scammers accidentally cough up IP address to Deadpool in card phish gone wrong

Re: Well?

Would it be possible in those sorts of cases where the police / CPS aren't willing to push for prosecution to take a civil case? Lower level of proof required but I can understand there are costs at your end involved.

It's Pi day: Care to stuff a brand new Raspberry one in your wallet?

Pihole all the way

If you've got your old Pi (or the new one) chuck Pihole on it. Amazing DNS based ad-blocking before it even hits the computer, it even works on my original model B. :)

The WHO don't exactly agree with you.

Though all your other points are valid.

P.S. Looks like they're avoiding using gas as its very expensive atm. Has the link been restored yet that was damaged around christmas from the rigs?

MY GOD, IT'S FULL OF CARS: SpaceX parks a Tesla in orbit (just don't mention the barge)

Don't know if posted already?

The main booster didn't run out of fuel. The rocket(s) failed to ignite on re-entry. The Beeb and the reg appear to have it wrong (source: Ars Technica).

Because our youth offenders institutions are infamous for turning kids lives around right?...

Li-ion king Goodenough creates battery he says really is... good enough

Depends what you're trying to show. If it's pressure then yes it's Physics but I like the the collapsing can for that one as the students can do it. I use the exploding for combustion :P, a bit more explosive ^^.

A lot of people seem to be rather confused over Lithium based batteries.

1. None of the batteries that you recharge use pure group 1 metals (lithium, sodium etc).

2. The reserves of lithium are pretty massive even without extra finds around the world 'a 2011 study by researchers from the University of Michigan and Ford Motor Company found sufficient resources to support global demand until 2100, including the lithium required for the potential widespread transportation use.'

3. The reasons why batteries once damaged catch fire is because of the sheer energy density they operate at, almost any material that undergoes a runaway thermal reaction like that will catch fire.

That would be chemistry, we still do that experiment now. Though it is damn hard getting hold of the Nescafe tins that are great for this.

It's called electrolysis ;)

They don't use pure alkali metals in batteries at all. It's in compound form or as an electrolyte.

It's all ions and has been for a long time. You're misunderstanding how a battery works.

I regularly do the thermite reaction inside, no issue at all apart from occasionally burning the ceiling.

Physics / Chemistry teacher

I regularly drop in the first 3 period group 1 alkali metals into water as the students have to know about the reactivity series, patterns in group 1 etc.

Lithium reacts pretty slowly with water compared to the other alkali metals even if you drop large quantities in. It releases hydrogen as all the alkali metals do on contact with water, fizzes on top of the water as the hydrogen creates a bubble layer underneath it. Sodium reacts in a pretty similar way except it's a little more vigorous, the amount you add does have an impact but it's fairly negligible (unless you drop hundreds of grams in!). Now, Potassium on the other hand even a 1-2cm3 size block will get you lovely lilac fireworks everywhere, large amounts will destroy the container.

This is of course all assuming you're using cold water, using hot water or an acid will create far more violent reactions.

Ironically this discussion is null and void as they don't use pure lithium in batteries, the lithium is the electrolyte (i.e. ions) and in a compound form on one of the electrodes. Though it would be interesting if they did start using pure but I don't see the benefit of it.

Latest Androids have 'god mode' hack hole, thanks to Qualcomm

My Note Edge has 3 vulns but hopefully it'll get patched fairly quickly as Samsung have been doing well patching everything with monthly updates, also as I'm using an unlocked phone no need to wait for the mobile networks to okay the patches!

Windows 10: Happy with Anniversary Update?

Cortana and tracking still all disabled

New install of Win10: Disabled all the telemetry and turned off Cortana. Rather than having to use reghacks and firewall rules I just used O&O ShutUp10 which is free and doesn't even need to be installed.

Upgraded install from previous version of Win10: Cortana still disabled, all tracking still disabled.

Why I use Win10? Firstly I game and the massive performance boosts I've had from DX12 (talking 40% here) are more than worth it, secondly as I work in the education sector I have to use software like Office as I need stuff to just work especially if I'm making resources for other staff members. I love Linux and used to use a variety of distros but libre/openoffice just don't cut it for compatibility and for stuff to actually work reliably.

P.S Please be gentle, I know the Register is very anti-windows (often for good reasons) but I'd rather I wasn't downvoted into oblivion for posting what I've found :).
