A group of friends are preparing for a party. Tasheera and Omar are in charge of preparing the balloons. Tasheera takes eight seconds to inflate each balloon, three seconds to tie each, and a five second break in between each one. Omar takes ten seconds to inflate each balloon, five Read more…
Today, I was asked how to select each element in an array as a separate row. In other words, I needed to convert an array into rows (one for each array element). Below is the right way to do it by using the built-in unnest() function (requires PostgreSQL 8.4+): If Read more…
I was surfing the internet a bit today and starting thinking about universally unique IDs. I came across this site which generates the UUIDs on the server side and then decided to make my own pseudo globally unique ID generator: You can use this function to generate as many UUIDs Read more…
Recently, since the DBA wasn’t available, I had to assume his duties and grant SELECT privileges to a user (let’s say john_doe) for all of the tables in the public schema. After quite a bit of research (Google of course), I learned about the pg_tables view. After realizing that this Read more…
As many of you may know, in JavaScript, you can define a date object by specifying a string that looks like a date. Recently I created a page using AJAX to get counter information, including the date/time that the page was hit. I thought that a pretty straight-forward format that Read more…
Over the past year I have been learning about so many different OpenSource packages it isn’t even funny. One thing that is available for free, but also has a paid version (which we at using at UniTek Global Services), is JasperServer. Right now we are on version 4.2.1. When we Read more…
The following is an implementation of a binary search for arrays which gives you the ability to do fuzzy matches (default), exact matches, or specify your own comparison function: I used the following to test the normal execution of this binary function:
One thing that I came to grips with today is the fact that if an error occurs in one of the functions that was bound to the document’s ready pseudo-event (I say this because the event doesn’t necessarily exist in every browser) by using jQuery, none of the subsequent callback Read more…
Sometimes I want to be able to write code like the following so that I can substitute a placeholder for a given substring: In order to get the above code to work, I wrote the following function: This function will take an arbitrary amount of arguments and return the string Read more…
Over the years, I have seen many different techniques for emulating the InputBox and MsgBox functions in JScript, but none of them were quite as elegant as the one I saw here. Once I dug into the code and realized that ScriptControl was making it so that JScript could run Read more…
