404 with Grails

Grails allows you to specify a custom 404 page simply using the UrlMappings.groovy class:
class UrlMappings {
static mappings = {
"500"(controller:"errors", action:"serverError")
"404"(controller:"errors", action:"notFound")
}
}

This allows you to direct to a controller where you can then forward to a view:
class ErrorsController {
def serverError = {
render(view:'/error')
}

def notFound = {
render(view:'/notFound')
}
}

I started off with a simple view using the 'main' layout:
<html>
<head>
<meta name="layout" content="main" />
</head>
<body>
Page not found!
</body>
</html>

But for some reason, the layout does not get applied. I haven't dug to the bottom of this yet, but I have found a work-around:
<g:applyLayout name="main">
<body>
Page not found!
</body>
</g:applyLayout>

Now the layout is applied and the page looks like I would expect.

The error page for '500' is fine, it only seems to affect the 404 page.

Intellij tip - Joining multiple lines into one

There are times when you have some code with each statement on its own line, and you want to move it all onto one line. CSS is where I've needed this the most. You start off with some code like this: And really want this: Intellij has a very simple way to do this by using Ctrl-Shift-J - for more information, see http://www.jetbrains.com/idea/webhelp/joining-lines-and-literals.html

Slow, Buffering, Stuttering Udemy Video

Udemy video has been completely unusable from my home broadband connection. Videos would take minutes to start playing and then continuously stutter and buffer. Searching for a solution I came across this Reddit post - and I found the solution was to change my DNS to use CloudFlare (1.1.1.1). After changing my AppleTV from automatic DNS to manual and using 1.1.1.1 video playback from the Udemy app has been as you would expect. I don't know why this helps, but it seems to have so far.

Memory upgrade for media center

I've noticed that my MythTV ( Mythbuntu 8.10) machine was using 100% of its 1G and swapping. (Incidently, I was running the Blootube widescreen theme, and just switching to the MythCenter theme resulted in a snappier experience). So, I went to buy more memory - and found that 1G cost AUD23 and a 2G stick was AUD45. Nice. I went for the 2G but when a friend commented that mixing a 1G + 2G I'd miss out on dual channel. Bummer, but I'll live with it. When I first installed the RAM, I put the new 2G chip in the same channel (A) as the existing 1G. Booting the PC reported 3G in single channel mode, but it wouldn't boot! It simply reported a CRC error and stopped! I took out the 1G stick, leaving just the 2G and booted okay. Hmmm, so now I put the 1G back, but in one of the channel B slots so the 2 sticks were in different channels. Now, when booting it reported 3G in Flex mode! I'd never heard of this so I looked it up. It all gets explained very well here , and what it...
