Greg's Stop Loss Kata

Testing is very hard when time is involved ...

A trailing stop loss is a term used in financial trading. For a very in depth explanation you can read here http://www.investopedia.com/articles/trading/03/080603.asp and http://en.wikipedia.org/wiki/Order_(exchange)#Stop_orders

However we do not need a huge amount of background in order to do the kata as we are going to limit the problem a bit.

The general idea is that when you buy into a stock at a price say $10. You want it to automatically get sold if the stock goes below $9 (-$1). If we use the term "trailing" that means that id the price goes up to $11 then the sell point becomes $10.

In August 2007 a hacker found a way to expose the PHP source code on facebook.com. He retrieved two files and then emailed them to me, and I wrote about the issue:

http://techcrunch.com/2007/08/11/facebook-source-code-leaked/

It became a big deal:

http://www.techmeme.com/070812/p1#a070812p1

The two files are index.php (the homepage) and search.php (the search page)

Making behat use phantomjs for the tests

If you want to run it on phantomjs (a headless browser) you can add this profile to your behat.yml and you need phantomjs >= 1.8.0

phantomjs:
    extensions:
        Behat\MinkExtension\Extension:
            base_url: http://dev.local
            goutte: ~
            selenium2:
 wd_host: "http://localhost:8643/wd/hub"

Never Expose DB Results Directly

1. If you rename a field, then your users are fucked. Convert with a hardcoded array structure.
2. Most DB drivers [for PHP] will show integers as numeric strings and false as "0", so you want to typecast them.
3. Unless you're using an ORM with "hidden" functionality, people will see passwords, salts and all sorts of fancy codes. If you add one and forget to put it in your $hidden array then OOPS!

Use the URI sparingly, and correctly

1. Use the query string for paired params instead of /users/id/5/active/true. Your API does not need to be SEO optimised.
2. ?format=xml is stupid, use an Accept: application/xml header. I added this to the CodeIgniter Rest Server once for lazy people, and now people think it's a thing. It's not.

/**
 * The ContainerAdapter allows the Symfony DIC to be used with phpmig. Phpmig is the tool that's used for executing
 * migrations on the application and expects a service container that implements \ArrayAccess. This is achieved by
 * wrapping Symfony's DIC with an adapter that implements \ArrayAccess and proxies to the DIC.

Notes

This is the latest version of an email which I send periodically, offering customers the opportunity to pre-pay for SaaS in return for a discount. The benefits to the SaaS company are better cash flow and reduced churn rate. The benefits to the customer are, well, in the email. This genre of email has produced hundreds of thousands of dollars in pre-pays for some companies I work with, and it rarely requires any more work than this example.

I've put $79 is as a placeholder for the cost of the user's plan. We calculate that for each account, naturally, along with the billing contact's name.
