Following their instructions to initialise the database, you get a complaing about /dev/null.

This is because the default postgres user is installed with a shell of /dev/null.

To change it, forget all the Unix stuff you know about administering users and do this


sudo dscl . -change /Users/postgres UserShell /dev/null /bin/sh


Or if you want to check first, check that the user exists

sudo dscl . -list /Users UniqueID


And then check the postgres user

sudo dscl . read /users/postgres


Needed to do this:


sudo locale-gen en_GB.UTF-8
sudo dpkg-reconfigure locales


sudo apt-get install update-manager-core
sudo do-release-upgrade

There’s a bug in (at least some versions of) Ubuntu, which means the wrong library is being picked up.

Workaround: LD_PRELOAD=/usr/lib/libneon.so.27 svn

if for example, you want to apply a unique index, but you can’t because there’s duplicates in the table.

SELECT name FROM mytable GROUP BY name HAVING COUNT(*) > 1;

svn propset svn:executable on

rngd -f -r /dev/urandom

This sends the output from the fast-but-not-very-random PRNG as input into /dev/random. Useful when testing and speed is more important than security.

I needed to get at the request in a template which had been called ‘direct_to_template’. To make the request available, you need to modify the TEMPLATE_CONTEXT_PROCESSORS variable.

Add this to your settings file

TEMPLATE_CONTEXT_PROCESSORS = (
    'django.core.context_processors.request',
)

Then you can use {{ request }}

It seems that browser refuse to install cookies for a TLD. So for example, if your local network is .internal, then you won’t be able to set a domain in a cookie for .internal. Add another layer into the domain e.g. .level2.internal, and the cookie will work fine.
