Just looking at ways to store my solar for use over night, a bit more extensively than the fridge. Plus I'd be very wary of turning a freezer or fridge off overnight here, defrosts very quickly.
They aren't practical for long-term storage, either due to energy density or due to their tendency to lose power over time pretty quickly.
I'd be curious to know what you consider long term, as it might not be as long as you think for a home storage situation.
I have a 1.5kwh array on my home, which generates a little excess during the day and of course, is useless at night:)
I've considered bumping it up to 3 or 5kwh as I get no effective use out of the excess generation (8c/KwH). However if I could buffer it for 24-48 hours then I could effectively power my house overnight. I live in Brisbane, Australia, so it would be effectively off grid for 80% of the year.
AMD supports openGL just fine, but they aren't gracefully failing sloppy programming. The Nvidia driver tends to try and make "something you probably sort of meant anyway" out of your illegal openGL instruction and AMD fails you hard with an error message. That's no reason to blame the manufacturer.
In computing, the robustness principle is a general design guideline for software:
Be conservative in what you do, be liberal in what you accept from others (often reworded as "Be conservative in what you send, be liberal in what you accept").
The principle is also known as Postel's law, after Internet pioneer Jon Postel, who wrote in an early specification of the Transmission Control Protocol
Its generally a good idea in when implementing a standard, if you want people to use it. Slavish perfectionism is the bane of developers that has killed many a project.
I give it another play around sometime soon, but it would have to other a lot more to persuade me to migrate now:) And our scaling needs are not large - might go up to 4(!) nodes next year.
Well windows has Remote Desktop (RDP), but I think that supports your point. I use xrdp for remote gui connects to my linux boxes as it performs a hell of a lot better than X, which is unusable on anything except a local LAN.
debian based system - trivial to install, uses KVM and Containers, nice web based admin system. Supports clusters and High Availability out of the box.
On the other hand, ask anyone who's actually had to administer an OpenStack system how they feel about it, and the response might be a string of curse words that would make your mother blush. This is a technology (or more accurately, a loosely connected family of technologies) still very much in its infancy, and sometimes it shows.

SMB here - We virtualised all our 6 servers and multiple test pc's onto a couple of grunty boxes. We looked at the cloud, but our net is to slow and unreliable (thanks Malcom Turnball for screwing the NBN).
Looked at OpenStack - a freaking nightmare to put together. Huge chain of dependencies and general flakyness. vSphere was too expensive if you wanted clustering, vmotion, replication etc. We eventually settled on proxmox - debian based using KVM, trivially easy to install and get running. Nice admin interface and basic backup facilities.
8 months on no real regrets, so sometimes regret not going with HyperV 2012.
Disagree, I've been using kmail2 with gmail & a rackspace imap server for some time now, its been flawless. Also using the google resource to integrate my contacts and calender, reliably synced between gmail and my android phone - something kmail1 was never able to do.
And with baloo replacing nepomuk, email search finally works - far faster than kmail1 ever was, I have over a 100,000 msgs which it can full text search in seconds.
All those cows, pigs, sheep, chickens etc are no longer going to be wanted by mankind. What this means is many thousands of years worth of natural and artificial selection will be wasted, most animals domesticated for meat will die out
I suspect there will always be a market for real meat, in the situation you describe I image real meat will move to being a delicacy and a luxury, hopefully supplied by animals farmed in a more "humane" manner.
I did S60 apps - worst dev system I have every seen - incredibly arcane and convulated dev chain, the C++ library had over *1200* classes. For a fucking mobile phone. And the class hierarchy was just perverse.
Agreed, shitty Marketing. I moved from my Sona Xperia Sola to a Lumia 525 - roughly the same price (contract free), heaps better phone - snappier, nicer to use.
This may be changing, seeing a lot more public awareness & pushing of the Lumia's in Australia.
Side Note:Development for Android and Windows Phone is pretty straightforward. I did some Symbian S60 dev in the past and that was just vile.
I've had the misfortune to be digging through a gnome program recently. The documentation is crap. Full of bad links, ambiguous statements and empty pages. Versioning is appalling, there is no list of documentation by gnome version.
When googling on the Qt4 api, I'll get a host of links to accurate offical documents, examples and informative blog entries. To a lessor extent it is the same for KDE (could do better).
With GTK/Gnome, 90% of the time I'll get a gnome.org page with broken links that is out of date.

No need, my hot water is solar.

YES. Finish Crusade.
I'm sorry, as much as I loved Babylon 5, it simply doesn't stand the test of time when you watch it in your 30s rather than as a teenager.
I watched it for the first time in my 30s and still found it absolutely brilliant. Just sayin'.
First saw it in my 40's here and I must agree - great show - plot, characters and yes the effects. I still think they stand up ok.
Still enjoy re-watching a season.
Nice summary, thanks.
This isn't the new desktop shell (Plasma2? PlasmaNext?), its basically the libs behind it, so there are no screen shots per se.
I must admit I find the new branding/naming conventions very confusing.
Wow. Just wow,

Nvidia is hewing to the following:

Interesting until you slagged off Qt. Its a superior framework and for me, vastly better than the mess that is Gtk.
I give it another play around sometime soon, but it would have to other a lot more to persuade me to migrate now :) And our scaling needs are not large - might go up to 4(!) nodes next year.
I did, easier than openstack to put together, but still very fiddly and at the time I tried it, required a min of three nodes.
Well windows has Remote Desktop (RDP), but I think that supports your point. I use xrdp for remote gui connects to my linux boxes as it performs a hell of a lot better than X, which is unusable on anything except a local LAN.
Oddly enough X gets along fine with crap remote display support.
Try proxmox (http://proxmox.com/)

Baloo is amazing, it actually delivers what nepomuk promised. I actually use ti regularly day to day - file, email & contact searching.
Skuemorphism is where we need to go back to. It worked fine the way it way and
I was with you till you mentioned Skuemorphism, that needs to die in a fire ASAP. Poxy volume control knobs in a mouse driven UI.
Obama is far left in what world?
USA World. Its another planet altogether.

They are disgusting, it's the same as eating insects - locusts, cockroaches, etc.
So they're yummy? deep fried locusts, crickets etc are delicious and much more ecologically sustainable than a vegan diet.
WTF? you do realise this is an article about Australian research?
