Overlap Detection
How does one detect when two strings overlap? In the case below, the four-letter suffix of string 1 matches the four-letter prefix of string 2. 1: "Fire at Will" 2: "William Riker is number one" Sometimes there are several matches; finding the longest is not always straight forward. 1: "Have some CoCo and CoCo" 2: "CoCo and CoCo is here." 2: "CoCo and CoCo is here." 2: "CoCo and CoCo is here."

Many times color palettes have lighter and darker variations of the same color. This may be used to convey relative importance, or for something as simple as a gradient. Usually the designer will specify both colors. However, if you have a site that needs to allow user configurable styling, you may not want to ask the user for two variations of the same color. Here is some Python code to take a single color in RGB, and output an artitrarily lighter or darker variation of the same color...

Can we believe our eyes?
Several days ago, one of our customers submitted a sample (SHA1: fbe71968d4c5399c2906b56d9feadf19a35beb97, detected as TrojanDropper:Win32/Vundo.L).

Lisp: It's Not About Macros, It's About Read
Note: the examples here only work with outlet lisp. Refer to your version of lisp/scheme’s documentation for how read works (and possibly other forms) I know it’s an old post by now, but something about the article Why I love Common Lisp and hate Java, part II rubbed me the wrong way. The examples just aren’t that good. The usage of macros is plain baffling, when a function would have been fine. The author admits this, but still does it. There’s a follow-up post wh...
