Kaj 23-Apr-2011 [5964] | I've even ported part of GNU Portable DotNet |
GrahamC 23-Apr-2011 [5965x2] | Is Java on Syllable yet? |
Is there a Syllable AMI ? | |
Kaj 23-Apr-2011 [5967x2] | We used to have the Kaffe VM, but nobody did anything with it, so beyond shouting that we must have it, there's no interest |
As I said, I haven't started with EC2 yet. I'd have to port Syllable Server to EC2. Syllable Desktop is impossible to run on EC2, unless you'd run it in a full emulator | |
GrahamC 23-Apr-2011 [5969x2] | Are people running desktops on Ec2 ? |
And I pre-paid for a 3 year Windows instance a month or so ago :( | |
Kaj 23-Apr-2011 [5971x2] | You could run remote desktops on a server, so I guess some people are also doing that on EC2 |
Admins like single points of failure ;-) | |
GrahamC 23-Apr-2011 [5973x3] | https://forums.aws.amazon.com/thread.jspa?threadID=65649&tstart=0 some guy was monitoring hundreds of ECGs on Ec2 :( |
All this happening a few days after that Chinese hacker group boasting that they could bring down any country's infrastructure :( | |
This fiasco has seriously dented the reputation of running cloud based systems. If the largest provider can't get it right, who can? | |
Kaj 23-Apr-2011 [5976x3] | Probably the smallest. They carry a way lighter load |
The uptime of our attic cloud compares quite favourably with many providers | |
Although now that I've said that, I'm sure the hot weather will soon blow out a hard disk... | |
GrahamC 23-Apr-2011 [5979] | You run your server in the attic? the hotest part of the house?? |
Kaj 23-Apr-2011 [5980x2] | Some days of the year, yes |
Then again, we don't have hundreds of heart patients hanging off it | |
GrahamC 23-Apr-2011 [5982x2] | I think I should setup a secondary fall back server in the Singapore availability zone. Hopefully what happens in the USA does not impact other regions. |
Amazon's talk of region isolation was clearly not true. | |
Kaj 23-Apr-2011 [5984] | Houses here don't have cellars anymore, because, as anyone knows, electricity is always there... |
GrahamC 23-Apr-2011 [5985] | Don't most Dutch houses have wind mills on them for power? |
Kaj 23-Apr-2011 [5986x2] | Just a few farms |
And besides, they run the machines that cut out the wooden shoes | |
GrahamC 23-Apr-2011 [5988] | and the wooden shoes are burnt to make steam? |
Kaj 23-Apr-2011 [5989x2] | When a hunger winter comes, yes |
That's when we eat the tulips | |
GrahamC 23-Apr-2011 [5991x3] | http://www.wind-works.org/articles/noiseswt.html search for Chiu to find out about the wind turbine I had on my house :) |
And here's a picture of my turbine http://www.compkarori.com/images/air403.gif | |
I have an inverter so that I could use the power from the 12V batteries to power my server | |
Kaj 23-Apr-2011 [5994] | It says you still have it but it will cost you tonnes to turn it on... |
GrahamC 23-Apr-2011 [5995x2] | I don't have it anymore .. the company took it away :( |
The threat of a $200,000 fine was a little too oppressive for me | |
Kaj 23-Apr-2011 [5997] | How big was it? |
GrahamC 23-Apr-2011 [5998x2] | not very big .. just over 1m span I think. Made lots of noise energy only! |
I think they use these on small boats where if the neighbours complain, you just sail somewhere else! | |
Kaj 23-Apr-2011 [6000x2] | :-) Yeah, I've seen those in recent years |
So they make too much noise because they're too small? | |
GrahamC 23-Apr-2011 [6002x2] | yes |
well, because they spin so fast | |
Kaj 23-Apr-2011 [6004x2] | That's the case with CPU fans, as well |
Size matters. The bigger the better | |
GrahamC 23-Apr-2011 [6006x4] | to shed energy ( so that they blades don't fall apart ), they undergo fibroelastic shudder |
which creates vortices and lots of noise | |
flutter | |
here's a picture from the roof .... http://www.compkarori.com/images/karori403.jpg | |
Kaj 23-Apr-2011 [6010] | I've been riding my bicycle under those really big ones in a big storm. Pretty impressive |
GrahamC 23-Apr-2011 [6011] | I thought I would be far away from the neighbours .. but clearly I was not |
Kaj 23-Apr-2011 [6012] | It looks quite close. The noise of small fans is very high pitched. It annoys the hell out of me, too |
GrahamC 23-Apr-2011 [6013] | I was going to short it during the night which basically puts a break on the whole thing. And leave it going during the day |
