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.

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.

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.

Nvidia is hewing to the following:

Robustness principle

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.

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.

Another megabytes the dust.
