Many people are familiar with the math game 24, but not many know about the sequential triad version. You must make each of the following sequences true by only inserting operators and without changing the order of the numbers: 0 1 2 = 24 1 2 3 = 24 2 Read more…
Hace un mes atrás yo anoté una diferencia en el número de visitas a mi blog pero no supe a que se debió hasta hoy. Google acaba de dejar el público saber que realizaron cambios en su motor de búsqueda alrededor de ese tiempo. Se puede preguntar, ¿por qué? Ellos Read more…

Last week I wrote a function which takes a file path and returns the base64 PNG code for that image. Since it isn’t straight-forward for everyone as to how to convert that JScript code to VBScript I decided to do just that: Feel free to use this code in your Read more…
Yesterday I was updating an HTA (HTML Application) and needed to figure out how to convert an image into a base64 code that could be used in a stylesheet. I needed this to be able to embed an image in the source code instead of referencing an actual image. For Read more…

Something that I need to use every once in a while is addEventListener, but unfortunately I can’t depend on its existence in all browsers. For this reason I decided to write the following cross-browser solution for providing a function that adds an event handler: One thing to note is that Read more…
After writing the Vernam Cipher post, I started thinking about alternatives to using bit-wise XOR in order to translate numbers. I started thinking about XOR for base 3. Therefore I concentrated on what makes XOR so great. What makes XOR stand out from other operators is the fact that assuming Read more…
