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.

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.
I'm not sure how else to name this entry, it's rather complicated. So what I was finally able to achieve is to pass a boost::bind to a boost::bind with placeholders, with templated callbacks. I'm not gonna lie, this took me awhile to figure out.
The rationale for all of this was that I had a parent class called group, and this group had the list of boost::asio::deadline_timer's and the boost::asio::io_service running in a thread. I wanted the ability for child objects to put work in that thread.
Django works much better if you do things the right way. Here are the steps for future me.

Part of my Why is simple hard? series.
Like most people with taste, I despise Hungarian notation. But, at the end of the day it really is only a style issue and easy enough to fix with a search & replace.
