Hemp Fibers Make Better Supercapacitors Than Graphene

blackpaw Re:suitable for home use? (178 comments)

No need, my hot water is solar.

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.

Hemp Fibers Make Better Supercapacitors Than Graphene

blackpaw Re:suitable for home use? (178 comments)

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.

Babylon 5 May Finally Get a Big-Screen Debut

blackpaw Re: And so it begins... (252 comments)

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.

KDE Releases Frameworks 5

blackpaw Re:Shame... (87 comments)

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.

AMD, NVIDIA, and Developers Weigh In On GameWorks Controversy

blackpaw Re:AMD supports openGL just fine (80 comments)

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.

OpenStack: the Open Source Cloud That Vendors Love and Users Are Ignoring

blackpaw Re:More virtualisation than cloud (99 comments)

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.

OpenStack: the Open Source Cloud That Vendors Love and Users Are Ignoring

blackpaw Re:Rolling it out as we speak (99 comments)

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.

Wayland 1.5 Released

blackpaw Re:Wayland is nothing until (179 comments)

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.

OpenStack: the Open Source Cloud That Vendors Love and Users Are Ignoring

blackpaw Re:Rolling it out as we speak (99 comments)

Try proxmox (http://proxmox.com/)

debian based system - trivial to install, uses KVM and Containers, nice web based admin system. Supports clusters and High Availability out of the box.

OpenStack: the Open Source Cloud That Vendors Love and Users Are Ignoring

blackpaw Re:More virtualisation than cloud (99 comments)

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.

+100

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.

KDE Ships First Beta of Next Generation Plasma Workspace

blackpaw Re:KDE 3 (94 comments)

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.

Bill Gates & Twitter Founders Put "Meatless" Meat To the Test

blackpaw Re:Watch Out for PETA (466 comments)

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.
