Re: [SLUG] quiet computer
If it's mostly the 2am noise that bothers you, the first thing you might try is turn off whatever is scheduled at that time. Popular offenders are prelinking and manpage indexing but there are many other possibilities. Turn them off or move them to say 10am in the morning when no one is around. You can also try out powertop (from intel) which is intended to find things that use a lot of power. Those things also of course tend to make the cpu run hotter and start up the fans as well. If you do enough plus some power settings, you can even get to the point where the machine goes to sleep when not used. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
Re: [SLUG] quiet computer
larger fans are quieter than smaller fans, and much cheaper than liquid cooling you can also get extremely large cpu coolers that will reduce noise. Dean Ken Foskey wrote: My computer is too noisy.

You can get very quiet CPU and PSU fans these days. (I've always found GPU fans to be the most problematic, because they're cheap and usually difficult to replace.) My current solution: An HTPC style case for my desktop system, which has no PSU fan at all (it uses a laptop-style power supply)... and a quietish CPU fan... which is getting louder with age. ;-) The server in the lounge room just has quiet fans, and is only audible in the dead of night, when the TV isn't on. Or when the disks go crazy.

Re: [SLUG] django/rails
I'd like to venture something but I can't really because I only know one side of this - ruby/rails. I think you could probably flip a coin and just go with one or the other. It might come down to picking a language. If python grabs you, then django is probably the way to go and vice versa. (If you like oop or iterators, ruby is probably your thing :) ) Both languages run on jvm and probably .net; I think jruby is maturing well from I what I've read (not done); don't know about python. That being said, I think rails has more recognition than django although both are probably not considered even close to "mainstream" yet and are likely to attract blank stares from grizzled verterans hunched in their trenches. If I were looking at django based on rails I'd be looking at: - testing: not only models but controllers and integration (sessions,cookies, moving around); also integration with more behaviour driven testing via rspec if you prefer that to TDD - handling of test, development and production environments including the database - migrations - incrementally adding stuff like new columns etc - authentication and other plugins like pagination etc - models/orm - activerecord is nice (you've got get your head around: associations, validations and callbacks - and it takes some time if you like punching out sql) although it's easy to end up generating large wodges of sql without you realising it - templating/views; I like erb and how easy it is to print and/or execute statements within a template; there are alternatives like haml which look cool; I can't believe how clunky php is by comparison - partials - rendering blobs of html within a template or other blob; this is a nice way to organise your templating - caching: page caching, fragment caching etc; so you can do expensive things and not feel bad about how wasteful they are :) - controllers: filters, sessions; subclassing controllers - debugging: ability to debug a live controller/model; although I rarely need to do this etc etc 2009/10/6 david > I'm reading up on both, trying to make an intelligent decision which to > use. > > I'm agnostic about ruby/python, although I have a faint feeling that python > may be better.

Re: [SLUG] MythTV issues
I know its windowsish, but have you tried rebooting? If some of the backend library's get updated when you start myth up again it'll be using the new libs but half the stuff its talking to will be using the old ones and it'll all get horribly screwed up.

Re: [SLUG] django/rails
I'm agnostic about ruby/python, although I have a faint feeling that python may be better. In either case I have to learn the language. Hi David, I use both python and ruby, but I prefer ruby. I find it easier to develop code incrementally in ruby because I can extract code into classes or modules with few modifications. I like the convenient syntax for passing and calling closures, and ruby's metaprogramming features are also often useful.
