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.

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.

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

Looking for IT work in Australia? JobReel.com.au!

I'm currently looking for contract work, and all of the usual places offer vague job descriptions that makes it hard to differentiate one from the other. This makes it hard to decide which ones to apply for, and almost always mean that you end up applying for jobs that are totally inappropriate. Now there is JobReel.com.au - much along the lines of jobs.joelonsoftware.com , positions must display the employer. I'm still looking for a site that lets me specify location, price range, responsibilities and technologies - but JobReel is closer than any of the others, and from what I've seen so far, the job descriptions are more useful and realistic. It looks relatively new to the scene - good luck!
