In your muttrc you should have something like the following:

set query_command = "goobook query '%s'"
bind editor <tab> complete
bind editor ^T    complete-query

and if auto-completion of aliases isn't working make sure you don't have:

bind editor <tab> complete-query
bind editor ^T    complete

Note that the complete-query vs complete. Ctrl-T runs your query_command whereas tab auto-completes as appropriate (likely from your alias list).

That took too long to figure out…

This pattern which I thought up (but is likely not unique) can very nicely manage your service configurations, automatically reload/restart your service, and even give non-root users (if desired) the ability to modify system config files.

All through the magic of git hooks. This example tracks config files for Apache (httpd).

Python tempdir.mkdtemp() has an annoying feature, it doesn't clean up after itself.

This idea comes from my friend and colleague Mike.

Do you have a function called Enable() and another called Disable(). Make those two private and make a third:

void Enable(bool enable) {
  if ( enable )
    Enable();
  else
    Disable();
}

// now change all your calling code from
if( x == y )
  Enable();
else
  Disable();

// to
Enable( x == y ); // 4 lines are now 1

As per my example above, four lines got compressed into one line but nothing actually changed. The algorithm is identical but you now have fewer lines to think about and worry about. And all of this multiplies. If you make that change 4 times you've removed 12 lines of potential bugs and oversights.

I've finally gotten around to uploading a little project I did years ago. any_config is a template class that implements a somewhat fancy prototype pattern.

Read about at github.com.

This was originally the majority of this post: Start a django project the right way but I've decided to put in it's own post instead.

I'm assuming you're on OSX. If you're on Linux most of these steps will be the same. If you're on Windows… Install VMWare and then install Linux.

I've added a tl;dr at the end.

Although I have tweaked this over the years, the original code came from (I think, I've long since lost the bookmark) klymyshyn.com

Don't check a pointer before deleting it, just delete it.

// don't do this
if ( p ) delete p;

// just do this
delete p;

// ie: this doesn't crash or do anything bad
int* p = NULL;
delete p;

// but you probably need something like this
#define NUL_DEL( p ) { delete p; p = NULL; }
NUL_DEL(p)

But seriously, this isn't the dark ages, you really want to be doing this.

std::shared_ptr<int> p;
...
p.reset(); // no need to set to NULL (or rather null_ptr)

I know next to nothing about Javascript so I'll need somebody who knows about this stuff to weigh in, but this is how I got jquery to load asynchronously and then fire callbacks.

Depending on the hardware involved, you can dramatically speed up an ssh pipe by changing the encryption type, or turning off compression.
