If you use MyISAM, you won't be doing **any** transactions per hour, unless you consider each DML statement to be a transaction (which in any case, won't be durable or atomic in the event of a crash).
Therefore I think you have to use InnoDB.
300 transactions per second sounds like quite a lot. If you absolutely ... |

Too bad it's not Oracle, or else you could use trunc() or to_char().

I don't think there is a built in way to get it from Python itself.
My question is, how are you getting the IP information from your network?
To get it from your local machine you could parse ifconfig (unix) or ipconfig (windows) with little difficulty. |
There's no way to specify a format with the helpers themselves. The approach you've taken will work. Another approach is to add the value pre-formatted into the ModelState. |

Datediff becomes more difficult to use as you have more dateparts in your difference (i.e. in your case, looks like minutes and seconds; occasionally hours).

You really should not access any derived classes from the base class as it pretty much breaks the idea of OOP. Readibility certainly goes a long way, but I wouldn't trade it for reusability. Consider the case when you'll need to add another subclass - you'll also need to update the base class accordingly.

Generally, the times when you will be required to transform XML data into a different form of XML data, but not do any other processing to it are going to be very limited.

It was basically a way of saying that in subsequent regexes (s/// or m//), the ^ or $ assertions should be able to match before or after newlines embedded in the string.
The recommended equivalent is the m modifier at the end of your regex (e.g., s/\n((\w*\-*\.*\w*\/*)+\:)/$1/gm;). |
You could write a function which would perform the conversion from price to string. This way you have a lot of control over the output.
The problem with locale is that it's web server dependent and not web browser dependent. |
It turns on multi-line mode. Since perl 5.0 (from 1994), the correct way to do that is adding a *m* and/or the *s*modifier to your regexps, like this

You need [ARP](http://en.wikipedia.org/wiki/Address_Resolution_Protocol).
