Malaysia Airlines Flight 370: Experts Unable To Replicate Inmarsat Analysis

wish bot Re:The explanation is simple (245 comments)

Just replying so that anyone else reading this isn't suckered in by your mistakes or ignorance:

1. Steel gets 'soft' enough between 500 and 700 DeC to lose most of its structural properties.
2. A typical fire - like something that could start in an office - can easily get to 700+ DegC. This includes the gas coming off the fire.
3. A bit of jet fuel could easily set most things inside an office building alight.

UN Climate Report Fails To Capture Arctic Ice: MIT

wish bot Re:Doesn't matter what they report (465 comments)

No actually that is all you have. There's plenty of historical evidence to indicate that temperature rise leads the atmospheric CO2 increase. The mechanism by which CO2 is theorised to retain heat is poorly understood and far from proven. Water vapour has a far higher heat capacity to act as a greenhouse gas and yet isn't accounted for in most of the models.

I see these statements all the time - unfortunatley they have become urban legend rather than having a basis in fact. Here's some reading:

Finally, I'm sitting here looking out the window watching it snow for the first time in ~70 years and have to seriously question your assumptions that the planet is even warming at all.

Here's something for this observation too - http://www.physorg.com/news/2011-03-global-snowstorms-scientists.html

As a counterpoint for anecdotal evidence, you may want to read the news stories about record heatwaves through the US over the past month...

Ask Slashdot: Self-Hosted Gmail Alternatives?

wish bot Re:SquirrelMail? (554 comments)

Isn't Squirrel just an interface? He's going to need something a little more than that - Postfix is the thing you need.

Now, having done exactly this for a long time (and having also moved everything over to Gmail for domains) I have a few observations:

- running your own email server gives you a warm inner glow and feeling of independence, but that's about it.
- check your logs daily, intrusion attempts happen constantly.
- dedicate the box to email only, that is - close down every port you don't need.
- don't run anything you don't need on that box.
- for the love of god don't run php (which might cut out squirrel mail).
- you'll need a set of good spam handlers. There's some good suggestions in posts below.

Personally, if you were really going to do this, I'd get a Mac mini. It comes with everything you need in terms of unix tools by default. It runs low power, it runs quiet. And there's slightly less chance of you getting owned. Always kep your patches up to date.

I eventually moved away from this because I got tired of being a paranoid sys-admin at home. Dealing with uptime issues also made me rethink what I was doing when email started to become critical to my finances - you'd be surprised how unreliable home dsl and power systems are when you really, really need them.

Alabama Nuclear Reactor Gets 'F' Grade

wish bot Re:That's a trivial thing! (436 comments)

Solar doesn't require batteries. It can feed directly into the grid via an inverter. Solar panels are near 100% recyclable and most manufactures have free recycling schemes. The carbon payback from manufacturing is as low as 1 year.

You also need to stop thinking of solar as a domestic production source - that's just perverse. Solar on industrial scales is already approaching parity with coal power stations and was cheaper than nuclear last year.

And yes, yes, it doesn't produce power at night. Maybe you've heard of power storage, which is already used in many places to help balance grid loads.

There are plenty of challenges, but so many geeks have blinkers on when it comes to solar.

80% Improvement In Solar Cell Efficiency

wish bot Re:Not the problem (204 comments)

Actually, most solar systems have a 'carbon' (read energy + transport) payback period of about 1 year. It's really good tech, it's just a shame so many geeks are obsessed with nuclear and so buy into the whole bashing solar routine, so you hear this kind of rubbish everywhere.

Robert X Cringely Predicts More Mininuke Plants

wish bot Re:I'd be open to it, but good luck with everyone (430 comments)

What do you mean 'scale'? It's not a database or load server. Maybe you need some educating too?

Wind and solar are perfectly viable if there's a will to commit to them. Similar to the arguments surrounding new generation reactors, wind and solar today is not the same as wind and solar of 40 years ago. Geeks are obsessed with nuclear to the point of blindness - it's embarrassing.

DHS Seized Domains Based On Bad Evidence

wish bot Re:Healthcare (235 comments)

Mate, why don't you just visit a country that has a functioning public health system. It shouldn't be hard, as pretty much every other 1st and 2nd world country has one.

Corporate America has been ripping off your health system for so long that you don't want it any other way. It's like a damn abusive relationship scenario or something.

wish bot Re:Astroturfing on Slashdot (353 comments)

Having noticed exactly the same thing, I had simply suspected that as Slashdot's popularity has grown it has become inhabited by very young impressionable guys, who's only experience (with computers, but thinking about it - extend that to almost anything) has been with Windows. Being young, male, and impressionable, they need to belong to a 'group' and it's easy to hate - and Apple is a very convenient target. Bashing Apple shows that you're 'one of the crowd' even though you've probably never used any system except Windows in your life. They get hints of what's 'accepted' by the crowd with the story summaries that are often written to inflame discussion to generate page hits.

It's self-reinforcing little world, and as a happy by product, may even encourage some people to use Linux. But what is most frustrating in this theory is the enormous amount of pure blind ignorance being channeled into the Apple hate.

Most of the Apple hate is venomous rants on issues that are at their heart the result of either absolute ignorance or intentional deception. Where you see intentional manipulation, I see a young immature burning desire to be accepted by something, anything. The true trait of a young isolated nerd.

The net result is the same however, and means that Slashdot is now largely devoid of moderating voices provided by experience people who have used more than 2 different operating systems in their lives, and for whom the choice of operating system is the selection of a tool to do a job, not a religion, and who probably have other healthy interests over being a full time nerd.

For other people stumbling across this comment - I'm not trying to flame, really. It's the honest observation of an old timer. One who seriously hope that this cuts too close to the bone of some of the crowd, as opposed to Bonch being correct.

Global Warming 'Undeniable,' Report Says

wish bot Re:More Info & Dashboard (1657 comments)

You should have listened to your grandmother. When potatoes are exposed to light, they turn green (yes on the outside first) which is the result of chlorophyll production, but also this also goes hand in hand with toxin production. You can also cause this in tubers by dropping and damaging them. This is why there is a belief that you should avoid the outside of a potato. I don't think you can fault your grandmother for not having a background in toxicity and agriculture, but she had some good info. You can look it up, but here's a quick summary from the CSIRO:

Are green potatoes safe to eat?

Green potatoes may cause food poisoning and since some of the symptoms are similar to gastroenteritis it is possible that some undiagnosed cases of gastroenteritis have been caused by eating green potatoes.

Human and livestock deaths have been recorded as a result of the consumption of greened or damaged potatoes with very high glycoalkaloid levels. It should be noted that glycoalkaloids are not destroyed by cooking processes, even by frying in hot oil. Consequently potatoes with pronounced greening or with signs of damage should not be eaten.

It is advisable that green or damaged potatoes are avoided by pregnant women or women who are likely to become pregnant, as there is some evidence of possible foetal damage or loss of the foetus from glycoalkaloid poisoning in animals.

So just maybe the scientist warning about global warming are right. Or maybe they're also in on a great potato conspiracy.

Does Anyone Really Prefer Glossy Screens?

wish bot Re:didn't ask the right people (was: Re:Yes) (646 comments)

You're a complete dick.

Glossy screens appear much brighter, and so have many practical advantages (including appearing more vivid). The 'want my matte' crowd are actually largely the fashion-victims, sprouting crap about colour distortions and reflections without any idea about what they are saying.

And Apple was one of the last to move towards gloss screens. Sony, HP, and Dell led the charge there you ignorant shit.
