Twitter and The Great Unwashed: how “normal” people ruined The Internet for the rest of us.

This article originally appeared in the Lawkit #4. Read more at http://lawk.it/

Once upon a time, everything was simpler.

A friendship was a construct based on shared memories and experience. The web was one of many, and it hung between idle walls. A tablet was something that came in a packet of 16 and the internet was the demesne of nuclear scientists and the military.

Discovering Sky Arts

It’s been out for a few months now, but I only discovered Sky Arts last night.  A proper Radio 2 like channel for those who left the MTV generation before they knew they were supposed to be in it.  They show some pretty cool music live shows and documentaries — this morning Eric Clapton’s Crossroads Music Festival and Mark Knopfler live in Basel were on the card.

Check it out. Better than rioting.

Leopard Mac Refuses to Stay Asleep…

The last week or so my Leopard iMac has been waking up in the middle of the night… it’s quite annoying.

Finally found the answer here:
macrumors – leopard imac waking from sleep issue.

It turns out the problem is caused by having Screen Sharing enabled, and the 5900 port (VNC) being exposed to the outside world through my router. While this allows me to remote connect from another Mac ….

The problem lies in the fact that the screen comes to life whenever ANYTHING connects to this port, be it another Mac, or a port scanner… before even authentication takes place. Tested this by trying to SSH to that port – bang, my monitors come to life.

Fixed it by removing the external port forward, and just using SSH into the Mac. Apple needs to stop waking up the screens until authentication has taken place.

Basically this means that the really awesome TouchPad app that got Fireballed a few weeks ago is only really useful if you turn off your computer (completely) at night or are willing to manually turn off port 5900 (the VNC port).

The weird thing is that this worked fine on Tiger.

So perhaps with Snow Leopard this won’t be a problem… ?

Rails Table Doesn’t exist!? Yes it does!

It’s happened to me twice in the last couple of weeks, and this time I knew exactly what I’d done, so here’s the solution if you make the same bad and non-“Rails Way” mistake I did.

dave@infinity:~/$ rake RAILS_ENV=production db:schema:load
(in /apps/special)
rake aborted!

Mysql::Error: Table 'special_production.pages' doesn't exist: SHOW FIELDS FROM `pages`

(See full trace by running task with --trace)

In my routes.rb file I had specified a route as such:
# map.connect 'special-day', :controller => 'pages', :action=>'show',
:id=>Page.find_by_title("Special Day").id

DON’T DO THIS. Not sure in what way it struck me as an overly good idea, but just don’t.
Strip that route out of your code and if necessary replace it as such:

# map.connect 'special-day', :controller => 'pages', :action=>'special-day'

What threw me about this problem is that I thought there was an issue in my schema.rb or migrations, this isn’t the case: ‘rake’ is trying to load the environment and falls over because ‘Pages’ hasn’t got going yet.

Don’t forget when you’re finished you may need to re-setup and migrate (cap deploy:setup / cap deploy:migrations) before your site will go.

P.S. This (silliness) never went into production!

Student Loans Interest Rates

Smashing on Rails

I’ve been working with Rails now for about 2-3 years on and off, for the last two months almost full time working on a project that I’m not talking about yet.
Via the great bunch of fellas at Contrast.ie I came across this article from Smashing Magazine on Rails which provides a great overview on a couple of things which I have picked up along the way and thought WOW that’s useful. They’re all here in one place.

Check out: Smashing Magazine: Ruby on Rails Tips

There’s a nice plug for Contrast’s current-big-thing web app: GetExceptional.
