Add that script to the payload malware usually carries, and spread it around, a few thousands bricks later, the negative publicity is sure to kill this whole UEFI thing, or at least force the hardware makers to include linux in their testing.

I don't understand. How is my botnet supposed to make me money if all the machines don't boot?

From the article: "Seems to violate law of conservation of momentum". - Yup it does. Imagine putting an invisible mass-less box around the entire system. Almost nothing comes out the back (only microwave energy - more on that later). The center of mass of the box accelerates. This is a violation of conservation of momentum - one of the most well understood and best tested laws in physics. If there were some exotic high energy physics effect proposed for this at least it might be worth listening, but this is just electromagnetism - very well understood. The "group velocity / phase velocity" is just jargon that has nothing to do with this since it is the Poynting vector that carries momentum.

You CAN make a reaction drive using photons (microwaves in this case), this idea has been around for many decades. The problem is that photons carry a lot of energy relative to their momentum so it takes an enormous power source to produce any thrust. So far no one has found a practical application where there was a large enough energy (and high enough power ) source to make this practical.

There have been a lot of experiments with microwaves - I've personally worked on a 600MW pulse microwave system. There have even been attempts at microwave driven spacecraft sails. Some early experiments seemed to indicate more thrust than would be expected from momentum conservation. Eventually this was tracked down to gas absorbed on the surface being heated and released by the microwaves - essentially a conventional rocket. With very high microwave powers you can generate forces in all sorts of ways in a closed laboratory environment that would not work in space.

This will not work.

If the microwaves blasted pieces of the resonation cavity out the back at super high speed it would appear to work in space. For a while.

My uncle got pulled over at an airport and detained for a good half hour because he 'looked nervous'. Well, yeah, it was the first time he'd ever flown.

Didn't feel much safer thinking that if there were any terrorists trying to get on his plane they were now quite free to walk through while the security agents dealt with him.

A good security guard would easily be able to tell the difference between someone anxious because of flying, or of large crowds, etc. Unfortunately from what i've heard they don't employ many of those.

It publishes 3 strips a week, plus a what-if from time to time. It's not a book, or anything else which would compete with whatever's on your kindle for your attention, unless you're a very, very slow reader.

The bigger problem is that Friday's comic was number 1168, so if you've only just started reading now you have a lot of catching up to do. Then half way through you'll realise that if you hover the mouse over the picture some additional text pops up so you'll have to go all the way back and start again[1]. Then you need to read the blag to figure out what all the references to cancer are about.

Most of the comics can be fully enjoyed in 30 seconds or less, but some require a bit more effort...

The What-If's come out once a week and also require a bit more attention but there's only a handful of them so far.

Neither one is as good as the original: Sir Mix-a-Lot.

I think you'll find that if glee had tried to cover the original, instead of a cover, it would have sucked more.

Might be a good way to make money - cover a popular song in such a way that it would fit within the capabilities of a bunch of semi-talented highschool kids and then wait for the royalties to roll in. Unless glee steal it instead of buying the rights to it... which they almost certainly will.

NSW in Australia has just survived a heat wave where there was recorded 50 degree Celsius in some of the bush towns. Where I lived, it hit 46 degree which is the highest temperature ever recorded

Whilst listening to the countdown yesterday I was pondering the idea that the warmest 100 is flawed because it only takes into account the votes from people who think the rest of the world cares about their every thought. Turns out I was wrong... I guess I'm a bit older than the Triple J target demographic these days - I wasn't 20 years ago though dammit!

Next year i'm posting my votes on facebook, just to throw it out a little bit :)

Never heard of it.

TripleJ Hottest 100 is actually a poll to vote in the top 100 songs of the year. I think the Eurovision is a different thing. If TFS was written by someone with the slightest bit of competence we wouldn't be having this conversation.

When you say "supplying", do you mean "selling"?

Nope. Or at least in Victoria. You give an 8yo alcohol and see what you get charged with when the parents find out. Whether the 8yo paid you money (selling) or you gave it to them for free won't make a significant amount of difference.

There are exceptions allowing a parent to supply alcohol to a minor, or others to supply alcohol to a minor with the parents permission, but that is an exception.

Wow, that's a crappy implementation.

VoIP should always be paired with PoE and a decent UPS. As long as you net connection was still live it would all have been fine

Actually most VoIP installations like that are using VoIP for the handsets and some combination of ISDN and fibre, and maybe VoIP to reach the outside world, so you don't even need an internet connection. When you're a large enough customer the savings for VoIP to reach the outside world often aren't worth the hassle (depending on what the telco competition is like in your country)
