That's not the best evidence. The most appropriate literature for this exposure is that pertaining to nuclear industry workers.
This is how the guidelines of 20mSv per year were derived. See this study for instance: http://www.ncbi.nlm.nih.gov/pubmed/17388693
there's no need to reinvent the wheel here, there is ample evidence that nuclear workers have higher risks of cancer and a population exposed to fallout from a reactor could reasonably be expected to have similar or worse outcomes (due to increased ingestion of isotopes)
I recently had a similar issue and now use:
Local:
3x 3TB Hitachi high end drives
RAID 5 in external enclosure.
Remote:
Data that is really critical gets synced using rsnapshot (incrementally)
to 'my own cloud', a dedicated server running Debian that I pay about $60 per month for (Fasthosts). It also runs a web/email/WebDAV server which is handy to access the incremental backups by the web.
This way I get redundancy with fast access and decent security (all over ssh). Running your own cloud is pretty trivial these days, well worth the effort.
Maelstrom by Peter Watts
The evolution of a viral soup on the net is illustrated beautifully in this (freely available) book:
http://www.feedbooks.com/book/975/maelstrom
It's a great read.
Viruses fighting for supremacy and interbreeding on the net may be an inevitable part of an evolving net-biosphere but
probably not the best thing to encourage!
...an abuse of the definition of shutdown. Reality check:
- 3 melt-throughs
- melted cores outside pressure chambers
- compromised secondary containments
- nuclear fuel and fission products escaping into water and air
- corium so radioactive it cannot be approached even by robots
- precarious leaning of number 4 spent fuel pool
- widespread plutonium, caesium etc. beyond evacuation zone
- significant contamination in food
- yet to come: increased malignancies and birth defects
Does this sound contained to you?
Seriously...
Milk accumulates radioactive iodine very efficiently. Shouldn't be radioactive iodine around anymore if there is no nuclear reactions happening as it has short half life.
Perhaps you should lead the way and offer to live in the exclusion zone when it opens. Also grow your food there and drink the water, tour the plant with your kids on weekends.
That is fantasy, of course, living in this area in even 100 years will result in a pretty decent caesium load even if you manage to avoid the heavier hot particles. If we ever see figures, compare pre-Fukushima explosion cancer and teratogenic rates with after, there's a lot of deaths still to come from this disaster. And a lot of land and sea that has lost its utility.
"seems clear that it is safer" - are you serious.
Your argument is a straw man the whole way, yes coal is polluting bit that doesn't mean nuclear is the answer.
I'll support nuclear when all the high level radioactive waste now crowding cooling ponds is in geological storage, oh wait, I forgot that would also make nuclear economically unviable.
A Melt-through has been acknowledged by TEPCO (see The Guardian 8th June article).
While I don't think I was being hysterical, that would actually be a pretty reasonable response to the event.
1) primary containment - pressure vessel failed
2) secondary containment (toroidal pool) failed
3) building breached by explosions
This IS worse case scenario. Plutonium 40km from site, contaminated water, food and soil.
And there is radiation still being released with no viable plan to contain it.
I'm sorry but cold shutdown implies there is still a functioning reactor to shut down.... Just smoke and mirrors...
Unbelievable they would claim 'cold shutdown' when reactor containment has been breached at 3 units!
More like: "the molten corium has burrowed deep enough to be cooled by groundwater and we are only reading 90 degrees at the twisted, melted reactor because the radioactive steam coming from below ground is dissipating the heat"
How reassuring.
There are basically 2 ways:
Install an 'appliance' mailserver like zimbra/roundcube
Or roll your own. I've been running a personal, small business server for years. It's great being able to give free email addresses to friends and family
I would recommend (on debian server):
-Postfix smtp with mysql backend and postfixadmin
-Dovecot imap
-Amavis/spamassassin/clamav for virus/spam filtering
Then you can throw on any web based client
I like horde but squirrelmail is good too. Horde has good groupware features and the new interface supports some nice ui features.
Also consider serverside filtering, horde has a sieve plugin which integrates with Dovecot in a cleaner way than squirrelmail.
Setting up a server is non trivial and you'll need to get your head around NAT, firewalls (iptables) and making sure you're not an open relay.
However, once it's running it's actually pretty maintenance free (unless you want corporate level security).
Good luck! There are some excellent howtos out there.
If the above sounds daunting, try an appliance first but there's a lot to be said for rolling your own.
The most environmentally sustainable and efficient way to achieve this is to reduce impediments to retrofitting.
Special, restricted registrations are currently required in most states, slowing down the number of people doing conversions.
Never forget that 50% of the energy of a vehicle is used in its production.
Therefore, changing to electric in older (preferably light) vehicles is a very viable strategy.
The best the government could do is shift fuel/road subsidies to better support the
initial outlay/recycling of lithium and tax heavy vehicles more to pay for this.
Then let the industry develop, there's already been hobbyists (with support of Sanyo)
who've squeezed a range of 1000km from a converted car...
So if the initiative is about raising the number of electric vehicles with the minimum cost,
retrofitting is the clear winner. But if its about handing out money to manufacturers to
to sell more cars that have already wasted half the energy and keep producing "hybrid prototypes"
then I'm sure we'll be talking about new cars...
In the longer term, public transport and support for cycling is a bigger winner anyway.
Why move a ton of steel/aluminium/plastic for an 80kg person, basic physics requires you to expend more
energy than any other means of transport...
Google bought Etherpad and Jotspotlive, two very advanced implementations of real time collaborative editing (albeit without some of the extra features of wave).
Can we please have them back Google? I was about to buy a decently priced server version of etherpad just before the buyout, and I thought, OK maybe with Google's
open framework they can do it better and give us a nice server/client package.
I have lost trust in Google, I think the Wave was too innovative for them, it allowed data to stay on separate servers, perhaps Google wanted more control over our data than that model allowed.
If Google has any decency about this, they should at least opensource the full web client implementation so that we can continue development.
There are many enlightened sysadmins that saw the potential of Wave but could not use it because it was non functional without a locally installed client for intranets.
So Google has killed two good projects to bring us..... almost nothing
Oh well... back to Moonedit for now, prove me wrong Google...
There is also another case rarely discussed:
The action of altering our affect on global warming may encourage feedback in temperature decompensation.
Let me illustrate. In Ayurvedic Medicine a method of lowering the body temperature during fever is to place the one with fever in a bath of water just WARMER then their body (1-2 degrees), therefore the heat is drawn into the water as it cools, without the body rejecting the cold (vasospasm, central shunting etc.).
When complex systems approach phase transition, unpredictability is the rule. Ice cores show rapid fluctuations in temperature ranges on the approach to the previous ice age (http://www.esd.ornl.gov/projects/qen/nerc130k.htm l).
What if? What if in our efferts to correct the climate we actually destabilise it more. Like in acute illness - skillfull inaction is sometimes the best method.
Keep one's ear to the ground, conservation and renewal of earth systems accompanies our own social evolution.
Yeah I agree, in fact, I regard the constant complaints about Spam as a type of spam itself! Really people, get a decent email server that doesn't sell your address to the highest bidder, don't give your email address to anyone you can't track down to a telephone number and just stop using Outlook.
It think that hydrogen is more than an energy storage medium, it is a means of encouraging efficient power usage. True, generating hydrogen from electrolysis using power generated from fossil fuel power plants is a no-win situation both thermodynamically and environmentally. However, there are other advantages to decentralised use of fuel cells. Hydrogen can be produced from power that is currently underutilised. It works well as a buffer for solar/wind power. Also, the storage problem may be remedied somewhat by reticulating hydrogen supply through modified natural gas pipelines. Generating power at the street level has other advantages; solid-oxide fule cells can also generate hot water (infact they need to be cooled). And let's not forget that we may one day be able to more efficiently convert water to hydrogen and oxygen by using sunlight directly (ie: artificial photosynthesis) - and we can use biomass to generate methane now. The main advantage from all these points is flexibility in the use of renewable energies at the local level - a good example of bioregionalism.
With all due respect: this is about more than just loss dollars. Dissent is what protects us from the type of complete control that large corporations and certain governments would love to have. What's more, humour is worth something too! Perhaps you should consider that business is essesntially evolved to consume vast amounts of resources to exaggerate economic growth so that more resources can be consumed (why do you think it's called busy-ness?) So a little disruption is worth a whole lot of political freedom... and it's fun!
If only it were so simple - genes explaining everything Sorry, this argument has never really gelled with me. First of all, organisms are organised on multiple hierarchies... so the 'build up from the base' analogy fails when macro interacts with micro and micro interacts with macro directly. The genes for good looks won't get you more children unless they happen to coincide with the cultural notion of what good looks are, for example. So a 'good gene' is not always good!
What's more, genes don't live in isolation even at the micro level, they interact with proteins and RNA and other molecules, energy fluxes and unexplained effects to yield coherent patterns of behaviour... organisation on multiple levels.
So, the good news is that you are not a slave to your genes or anyone elses. It is the will to imagine the future that is the most potent evolutionary force....
I, at least, have the will to resolve conflicts without resorting to mechanistic 'my genes made me do it' excuses.
I think the whole point is that it doesn't have to be motivated by profit. A good example is the Melbourne network currently being set up http://www.wireless.org.au
Admitedly, we pay crazy prices for bandwidth in Australia (I pay $80AU/month for ADSL with static IP) but this is why it stands such a good chance here... but only if the cost of piping a net connection is shared between the users. Essentially WiFi, in my opinion, is about high speed community networks. As the number of users increase, the telcos are going to want to use our kickarse network rather than us using theirs! OK, maybe a little optimistic but not when you consider what you can do with a good map of APs plus mobile devices running IP v6 and some funky routing.
I, for one am building a setup based on my iPAQ to share my DSL to the local cafe for a start and then with some nice antennas, link in to the rest of the wireless net (maybe using my bicycle to recharge my batteries...)
