Selecting an Epoch to count from

Sam — Fri, 30 Apr 2010 21:11:15 +0000

When starting a project a good way to select an epoch would be to select the closest year in the past that is divisible by 400.

This will simplify time conversions to / from days since epoch to years as
Years that are evenly divisible by 100 are not leap years, unless they are also evenly divisible by 400, in which case they are leap years.

Blue Ink

Sam — Sun, 20 Sep 2009 04:15:28 +0000

Weird thing about some government forms is you cant use blue ink. There should be a list of reasons for this. Here are some of my suggestions.

And the color shall be black. Not Grey, nor green or yellow. Red is right out.

If any other color than black is used the writer shall perform tracing jobs over all blue.

The reader of this document may be color blind to any color than black.

Visual Command Alpha 0.0.0.0.0.1

Visual Command

I have been playing around with this idea since I graduated in May. I learned a lot about QT from this project.

It can dynamically create an interface for a command prompt application.

It currently uses check boxes, numerical integer , and strings as inputs.

Files, doubles, and sliders will be next, along with a way to upload/download GUI interfaces to a server.

It was built using QT over the previous month. Never used Qt before so it was more of a learning experience.
