pip install MySQLdb

27 Jan 2014 In case you haven't already noticed, the command in the title won't work.

You need to use: pip install MySQL-python

This article explains the correct approach: http://mysql-python.blogspot.com/2012/11/is-mysqldb-hard-to-install.html

Best VNC Installation Guide

18 Jan 2014 https://wiki.amahi.org/index.php/Install_VNC_server_on_Ubuntu_Server_12.04

That guide gave me the least amount of hassle when I installed VNC on a server. I started by trying to get it working with 13.10, but had issues with a grey screen when tightvnc connected.

"Could not connect to database: Database connection "Mysql" is missing, or could not be created." - CakePHP

15 Jan 2014 I got rid of this error just by creating the database manually. Shouldn't Cake do this?

"Not Found The requested URL /app/install was not found on this server." - CakePHP

15 Jan 2014 Rather than dealing with my .htaccess problems to fix the error, I thought this would be a better approach: http://wwdj.wijndaele.com/getting-started-with-cakephp-without-mod_rewrite/

Unfortunately, it messed up quite a few links on my site.

I ended up solving the problem by changing "AllowOverride" None to "AllowOverride All" in my /etc/apache2/sites-available/default file.

Why the heck is CakePHP using .htaccess files by default anyway? Yii has this more streamlined.

CakePHP Boilerplate

There's also this one, but it has much fewer commits: https://github.com/zynesis/cakephp-boilerplate

Exception in thread "main" java.lang.NoClassDefFoundError - Java

How To Use Endpoint Parameter - Flask-Admin

03 Jan 2014 You can access the endpoint parameter by using self.endpoint.

class displayResults(BaseView):
@expose('/',methods=('GET','POST'))
def index(self):
print self.endpoint

admin.add_view(displayResults(name='test', endpoint='test2'))

That will print "test2".

UndefinedError: 'admin_base_template' is undefined - Flask Admin

02 Jan 2014 This happens when you try to render a template like this:
return render_template('admin/upload.html')

You need to use self.render instead:

return self.render('admin/upload.html')
