Chernobyl's Sarcophagus, Redux

The "gas that mixes with the air" is not that much of a problem nowadays, the concrete will mostly cover that. What's leaking from below, on the other hand...

Star Cluster Ejected From Galaxy At 2,000,000 MPH

siddesu Re:Velocity (133 comments)

would we notice the effects of such an ejection?

Effects will depend on the differences of acceleration of different parts of the cluster. Because the speed has probably increased over many millenia, and because it is still a cluster, they were most likely very hard to observe.

Star Cluster Ejected From Galaxy At 2,000,000 MPH

siddesu Re:Velocity (133 comments)

2 mil miles per hour is something like 1000 km/s. Considering that the escape velocity on the surface of the Sun is something like 600km/s that's not pedestrian at all.

Physics Students Devise Concept For Star Wars-Style Deflector Shields

Most of the 'stormtroopers can't hit shit' hate comes from the insignificant number of Ewoks that they killed. And I understand that hate.

Decommissioning Nuclear Plants Costing Far More Than Expected

siddesu Re:First.... (288 comments)

Gen 4 reactors will happily run in a way that it effectively reprocesses its own waste. It's also got passive safety and the resulting waste (which at this point really isn't fuel) has a half-life well short of the hundred years.

They are also fictional. We'll be able to judge how well they operate and how they reprocess own waste when we see one operating safely for some time.

Decommissioning Nuclear Plants Costing Far More Than Expected

siddesu Re:First.... (288 comments)

No, it is not fuel. Part of it may become fuel if one is allowed to reprocess it. Reprocessing, however, is a very tightly regulated business, and in many places, for example in the US, or in Japan, or in Russia it is not an option, or not a very important option. Do you know why it isn't a wide-spread, happy industry? Yep, because it is expensive as hell, dangerous and dual-use.

Here's a fun experiment to do: stop pretending you carry a cesium source and a Geiger counter, and consider what should be done with the 1000+ tons of highly radioactive mud that is already collected on-site in Fukushima. Right next to the used fuel pool.

Please make it a rational solution that can guarantee no leaks for a few hundred years and doesn't cost a brazillion billion million yen.

Thanks.

Decommissioning Nuclear Plants Costing Far More Than Expected

One, you have serious reading comprehension issues. OP claims coal produces more nuclear waste than nuclear power.

Two, that SA article has been debunked so many times, it isn't even funny. The 'research' it is based on is from 1977 and it discusses coal plants that aren't built anymore. Here, for your reading pleasure: http://tech.slashdot.org/comme...

How Concrete Contributed To the Downfall of the Roman Empire

How Concrete Contributed To the Downfall of the Roman Empire

siddesu Re:Fall of the Republic, birth of the Empire. (384 comments)

Even this claim sounds quite far-fetched to me.

What certainly played significant role in bringing down the Republic was the inability of the Romans to adapt their political system, which was quite efficient in running a city-state (or a loose union of several city-states), to govern the huge country their successful military campaigns created. It simply didn't scale well enough.

Another big hurdle, IIRC, was the impossibility of legal reform because the Roman viewed the laws of their forefathers as sacred. The legal mess they got on their hands in the last years of the Republic allowed all kinds of manipulation of the political system -- something which Caesar and his successors used skillfully to gradually take over.

I don't think we have enough facts to ascertain the role of the concrete in this process, though.

How Concrete Contributed To the Downfall of the Roman Empire

Actually, the premise that the Roman Empire fell because Julius Caesar began thinking like a king seems a bit wrong. The Empire was established after he died, after all, and lasted for hundreds of years after his death.

Why the Sharing Economy Is About Desperation, Not Trust

Why the Sharing Economy Is About Desperation, Not Trust

siddesu Re:Maybe it is neither (331 comments)

I think this is a hard case to argue, and the reason is most often the failure of the political process to properly assess the economics of the measures. Usually, the better the assessment, the better the chances of success, but government involvement is hardly a 100% success story.

Why the Sharing Economy Is About Desperation, Not Trust

siddesu Re:Maybe it is neither (331 comments)

Your problem is that you have the basics backwards and you try to solve this by arguing over definitions, and then you devolve in 'open your eyes sheeple' crap. This doesn't make you right, however.

Capitalism, a mode of the economy in which factors of production are privately owned and their output is voluntarily traded, exists all over the world. The 'free market' you're talking about is one idealization of one aspect of this system. Unlike capitalism, it is this 'free market' (the correct term is 'competitive market', where nobody has any power to dictate factor or good prices, or output levels) that does not exist.

Your attempt at analysis is also faulty because you aren't making distinctions between how and why phenomena that have similar effects come about and develop. A market distortion that occurs in a 'free market' under a natural monopoly (and yes, in the absence of government regulation, a natural monopoly is a 'free market', although not a competitive one) is a very different beast from the distortions of an economy that develop under a corrupt government, although they may share some similar effects once in place.

The problem I'm discussing is that a democratic political system operating a capitalist economy tends to reliably get into the state you call 'crony capitalism' over time because of the way the two interact, free market or not. Hence the need for an improvement. Pushing for a 'free market' utopia is about as much a solution to this problem as pushing for a communism of the Marx variety would be.

Why the Sharing Economy Is About Desperation, Not Trust

siddesu Re:Maybe it is neither (331 comments)

In my experience, this model has the potential to work successfully only in areas of the economy that are 'market failures' (i.e. significant departures from competition and economic efficiency) for some reason. And it is damned hard to get the proper regulations and controls right even then.

Japanese "cyber crime" suspect arrested for petting a stray cat

siddesu siddesu writes  |  about a year and a half ago

siddesu (698447) writes "A man was arrested this morning in Tokyo because he was videotaped approaching a famous stray cat in the popular tourist destination of Enoshima near Tokyo.

The animal was used some months ago to deliver (via an SD card strapped to its leash) a message ridiculing the cyber crime unit of the Japanese police for their failure to apprehend a "hacker", who posted "threatening messages" to several popular boards.

The investigation of the pranks since October last year has so far resulted in four arrests of innocent people."

Room Temperature Superconductivity Found in Graphite Grains

siddesu (698447) writes "Here's an interesting recipe. Take a spoonful of graphite powder and stir it into a glass of water. Leave for 24 hours at room temperature and then filter the powder. Finally, bake overnight at 100 degrees C and allow to cool.

And voila! A material that superconducts at over 300 kelvin--room temperature. At least that's the claim today from Pablo Esquinazi and buddies at the University of Leipzig in Germany."

File organization - how do you do it?

siddesu siddesu writes  |  more than 3 years ago

siddesu (698447) writes "After 30 years of being around computers, I have, like everyone else, amassed a huge amount of files in huge amount of formats about a huge amount of topics. And it isn't only me — the family has now a ton of data that they want managed and easily accessible.

Keeping all that information in order has always been a pain, but it has gone harder as the storage has increased and people and files and sizes have multiplied.

What do you folks use to keep your odd terabyte of document, picture, video and code files organized — that is, relatively uniformly tagged, versioned, searchable and ultimately findable, without 50 duplicates over your 50 devices and without typing arcane commands in a terminal window?

I found this discussion from 2003 and this tangentially relevant post from 2006. How have things changed for you in 2011?

And how satisfied is your extended family with the solution you have unleashed upon them?"

Apple bans online sales in Japan

siddesu siddesu writes  |  more than 4 years ago

siddesu (698447) writes "Japanese big retail stores were ordered a week or so ago to stop selling Apple products online. The comments in the Japanese business newspapers suggest that Apple believes online shopping adds an aura of "cheapness" to their products, but killing the competition of the Apple store has surely been considered as well. As of today, most of the largest retailers have notices on their Apple catalog pages that ask you to kindly visit the shop if you want to acquire a piece of magic. It seems that for the moment the campaign is aimed at the big fish, as smaller shops still seem to carry and sell Apple items.

Quantum effects behind photosynthesis efficiency

siddesu (698447) writes "Wired has a fascinating story about a recent discovery that sheds light on the quantum physics mechanisms behind the efficiency of photosynthesis. Antenna proteins appear to "use" quantum effects to route energy almost without loss from photon-sensitive molecules to nearby reaction-center proteins, which convert it to cell-driving charges. As a bonus, the article provides a car analogy."

2025 NIC predicts multipolar and dangerous world

This is a much gloomier outlook on the world compared to the report from only two years ago. Dig that shelter and stock up on ammo where legal.

skype helps chinese authorities snoop on messages

The system tracks text messages sent by customers of Tom-Skype, a joint venture between a Chinese wireless operator and eBay, the Web auctioneer that owns Skype, an online phone and text messaging service."

brain evolution similar to hardware development

siddesu siddesu writes  |  more than 6 years ago

siddesu (698447) writes "A new research by the Sanger institute suggests that the widely accepted view that brain power is a function only of size and that nerve cells are similar accross species is incorrect, and that complex brains depend not only on the number of neurons and connection, but also on the complexity and capabilities of its neurons.

The study compares proteins found in synapses accross many species and finds that in simpler organisms not only the brain size is different, but the number of proteins in their neurons is also significantly lower than that of animals with complex brains or humans.

This suggests that complex brains need more complex "hardware", and that the evolution from simple sensory "components" (as found in the various yeasts) to the complex neurons that build the human brain is similar to the development of computer hardware."
