The only representation that I have seen in use (though, admittedly, my experience is limited to [DOJO](http://dojoframework.com/)) is [ISO 8601](http://en.wikipedia.org/wiki/ISO_8601), which works nicely, and represents just about anything you could possibly think of.

You can debug any ODBC driver by activating the logging for it via the Control Panel.
Just go to driver's properties, activate the logging and set the target log file - and then set up another program to read from it interactively, so you can see what's going on. |
There's also [Scruffy][1]. I took a look at the code recently and it seemed easy to modify/extend. It produces svg and (by conversion) png.

Ruby on Rails Migration - Create Schema |

I have a migration that runs an SQL script to create a new Postgres schema which seems to work fine.

> range creates a list, so if you do range(1, 10000000) it creates a list in memory with 10000000 elements.
xrange is a generator, so it evaluates lazily.
This brings you two advantages:
1. You can iterate longer lists without getting a stackoverflow error.
2. As it resolves each number lazily, if you skip th... |
The error "Row not found or changed" also will appear sometimes when the columns or types in the O/R-Designer do not match the columns in the SQL database, especially if one column is NULLable in SQL but not nullable in the O/R-Designer.

There are good reasons to use an instance logger. One very good use case is so you can declare the logger in a super-class and use it in all sub-classes (the only downside is that logs from the super-class are attributed to the sub-class but it is usually easy to see that).

In order to work around the performance cost of reporting via db4o, I'd suggest maintaining a highly denormalized (sqlite ?) database in parallel to your db4o container. Run reports against the db and normal app logic against db4o.

How can you measure the amount of time a function will take to execute?
This is a relatively short function and the execution time would probably be in the millisecond range.

I think you're missing a fundamental key of the SOAP protocol.

Use Snort, stripped down, if this is a long-term thing. It's built to watch for particular packets flying by, examining payload where needed, recording data and launching alerts.

I'm with Guy Starbuck here, but would add that Rebuild Solution is supposed to do a Clean Solution followed by Build Solution, which should, then, have solved your issue to begin with.

This sounds strange - Rebuild should build everything regardless of changes and Build should only build things that have changed.

It looks like your GET argument is itself an array. It would be helpful to have the input as well as the output. |
This way fits in better with the rest of the language. The convention in python is that you add `__foo__` special methods to objects to make them have certain capabilities (rather than e.g. deriving from a specific base class). For example, an object is

Remember to *program into* the language rather than program in it. Just because you're using a limited tool-set doesn't mean you have to program like it's 1999.
