Today I have 2 tips for Total Commander users:

• how to display hidden local directories and files and
• how to display hidden FTP directories and files

Really, Total Commander should just control this setting in one place but, unfortunately, it is not the case.

I usually prefer when my file manager shows me everything I have, so that I can be more in control and see the hidden directories, such as .svn or $Recycle.Bin, and files, such as .bashrc or pagefile.sys.

How To Display Hidden Local Directories And Files

• go to Configuration -> Options… -> Display
• put a check next to the "Show hidden/system files (for experts only)"

Introduction

StackOverflow is an amazing site for coding questions. It was created by Joel Spolsky of joelonsoftware.com, Jeff Atwood of codinghorror.com, and some other incredibly smart guys who truly care about user experience. I have been a total fan of SO since it went mainstream and it's now a borderline addiction (you can see my StackOverflow badge on the right sidebar).

The Story

Update 6/21/09: This server is currently under very heavy load (10-200), even with caching plugins enabled. Please bear with me as I try to resolve the situation.

• easiest session of all (phew, that's a relief)
• clever SQL recipes
• tweaking SQL queries
• shows an example where SELECT is ORDERED by a column that is actually an enum.

• an enum is both a string and a number
• sorted by number
• displayed as string
• can be sorted by string if it's cast as string

• compacts storage
• faster to search
• if (var)char is turned into enum, some space can be saved, shows example

• order by rand(1) – obviously
• the integer parameter is actually a seed
• really slow, also obviously, especially for larger tables because it has to order first, then apply rand() to the list
