Visually ageing folders (change folder icon in Explorer based on last modified time)
- by Grynn
This sounds like a really good idea: Ageing Icons with Freshness App Unfortunately the "demo" is Mac only. How would you go about replicating this on Windows? One approach I can think off is to modify the desktop.ini file within each folder. This would require a service that periodically scans some folders and updates the desktop.ini file.

Implementing a 30 day time trial

Putting the counter in a hidden file somewhere sounds a bit dodgy - as a user I hate when apps sprinkle my hard drive with random files. Any ideas?Read the article

PHP Round Minute to nearest Quarter Hour

I need to round times down to the nearest quarter hour in PHP. The times are being pulled from a MySQL database from a datetime column and formatted like 2010-03-18 10:50:00. Example: 10:50 needs to be 10:45 1:12 needs to be 1:00 3:28 needs to be 3:15 etc. I'm assuming floor() is involved but not sure how to go about it. ThanksRead the article

Making one value "special"
- by SplashHit
What is the "computer science" term for the practice of assigning a special meaning to one of a type's values. For example a numeric variable called "amount_to_transfer" where the special value "0" means "entire account balance" or a date value "spouse_date_of_birth" where "1/1/1800" means "unmarried". I happen to feel that this is quite a bad "smell", but I'd like to have a name for it, and if possible, some blog post or article about why it's bad and how to fix it.Read the article
