Nautilus (which is at enterprise.ucc.gu.uwa.edu.au and seems to think it's called Bow) is currently running Mac OS Z1-9.1. In the Startup Disk control panel, I can select from that or an HFS+ partition containing Mac OS X 10.1.5. There don't appear to be any other partitions attached. It's accessible over VNC but it's pretty slow :-) I think that's the machine I never managed to get the mirror driver running on.

Here's my pitch: design-wise, it drops the rapidly-aging header graphic from the old website and provides a range of quick-access links in the header - users shouldn't have to 'dig around' on the site to find something. On the back-end I'm using ikiwiki backed onto git: it's fast and stable (because it generates static html) and because it uses a conventional revision-control system, you can check out the sources and edit it in whichever editor you like. For quick updates, you can also edit in browser. Of course, it brings all the well-understood power of a wiki to the site too, and has a design created from scratch with free software. What I haven't addressed yet are the domain-specific issues: content and structure. I present to you my proposal for a new UCC site structure (which is really not that different from the old one) as a wiki page on the site in development itself: http://ucc.asn.au/ver2/sitemap/ Note that this is a design only and most of the links don't work and header doesn't reflect the currently selected page. The 'edit' link does work and presently uses OpenID and local ikiwiki accounts for authentication. Feedback from IRC has been mostly positive, the most common complaint being about the design: that the text is too small. I haven't used a desktop in two months, so I'm not in much of a position to comment, but minor cosmetic changes aside - do you think this new design, structure and backend will work for a replacement UCC website? I'm not sure how reliable (read: existent) my internet access is going to be in the next few days as I rough it on cheap transport through southern Thailand, so I might not be able to reply/defend my choices/throw a hissyfit and threaten to leave the club as quickly as you're used to in discussions like this. So: have at it, tell me what you like and what you don't like - check out the sources if you'd like to have a play around (they're on mussel:/usr/local/git/ucc-site) and let's see if we can get the ball rolling on an update to the website again!

The AC unit sucks up 0.75KW of power from the socket but using that energy to drive its pump/fan it exchanges 2.25KW of heat from inside to outside. 2.25/0.75 = 300% efficiency, the commonly claimed figure is 400% or 4:1. I'm guessing this is because they assume all the heat from the AC unit itself ends up outside? Most of the bulk is hanging outside the window after all.

I've done some more research, and this model is the only window-wall airconditioner of ~6kW available in australia. Split systems are more expensive and also have installation costs. So my recommedation is we start fundraising towards buying this model. The only question is whether to go for the $99 extended warranty, which takes it from 2 years to 7 years. -- # TRS-80 trs80(a)ucc.gu.uwa.edu.au #/ "Otherwise Bub here will do \ # UCC Wheel Member http://trs80.ucc.asn.au/ #| what squirrels do best | [ "There's nobody getting rich writing ]| -- Collect and hide your | [ software that I know of" -- Bill Gates, 1980 ]\ nuts." -- Acid Reflux #231 / From astro at jaram.net.au Mon Mar 23 20:27:50 2009 From: astro at jaram.net.au (Jeremy Cole) Date: Mon, 23 Mar 2009 20:27:50 +0900 Subject: [tech] New aircon (was: Anyone in the clubroom?)

[6100W cooling window-wall / window-box style] That's good value, bounteous BTU's/buck, even with the extended warranty. I am a little worried about having one big aircon, though, unless we have a pre-approved contingency plan to buy perhaps a slightly smaller replacement at the first sign of trouble. There's a lot of running around to get a warranty repair, especially if the first few failures are intermittent. The window-box, gibson, was bought on 20051217 with a five year warranty, it iced up a few times, then died around 200710. [DAA] got it fixed under warranty in 200802 and it's died again, tripping circuit breakers, at 200901. (Still under warranty, at least on the compressor) If it had been an unremovable split system requiring a professional callout for repairs or maintenance I expect it would've been even harder to organise that fix. So... we could leave atacama running and add a portable aircon. They're not great, but they might be easier in practice to swap or repair. http://www.delonghi.com.au/products/product_details.asp?Model=PACC100 http://www.retravision.com.au/ProductDetail.aspx?ProductId=7346 2930W cooling, $699, specs look good http://www.theelectricdiscounter.com.au/asps/productpage1.asp?model=KPK35CRB&extwarranty=3EWAPP1000 3500W cooling, $625 http://whirlpool.net.au/wiki/?tag=aircon_faq Nick. -- Nick Bannon | "I made this letter longer than usual because nick-sig at rcpt.to | I lack the time to make it shorter." - Pascal From maset at ucc.asn.au Mon Mar 23 23:12:36 2009 From: maset at ucc.asn.au (Anil Sharma ) Date: Mon, 23 Mar 2009 23:12:36 +0900 (WST) Subject: [tech] New aircon (was: Anyone in the clubroom?)

[LOL] is going to look into getting gibson repaired (again), and atacama is working fine -- so, if we purchase the air conditioner [TRS] recommended, then we'll have one (and hopefully two) small air conditioners to use as a backup should it fail. The consensus at the meeting was that we'll start fundraising for (and eventually buy) the 6 kW unit that [TRS] recommended as long as tech@ and wheel@ approve. So, does anybody object to purchasing the Kelvinator KWH62CRA for $943, incl. 7-year extended warranty, given that we have one smaller aircon as a backup, and we may have gibson running again soon? If I don't hear from anybody in the next few days, I'll send out an email to ucc-announce@ asking for contributions.
