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…
If you have ever taken an encryption class, I am sure that you have heard of the Vernam Cipher. For fun today I decided to write a quick one in JavaScript which takes your message and the random key: To you use this function you must supply both a message Read more…
Nearly a year ago I wrote a quick post about the awesome heredoc notation for strings in many languages such as PHP: Unfortunately, this doesn’t exist in JavaScript. If for some reason you do need to fake it though, you can use a comment in order to achieve your goal: Read more…
Recently I was working on an HTA which contained an element that I wanted to be resized when the window resized. The issue was that I only wanted the resizing to occur after 0.5 seconds elapsed in which the user was not resizing the window. For this reason the debounce Read more…
At times when dealing with functions that will be bound to an element you may need to prevent that function from being run multiple times. In order to do that you could use a JavaScript library such as jQuery and bind the function with the jQuery#one function. If that is Read more…
Today I worked on a project which involved weighted randomization. In other words, I had to randomly choose an item from an array of weighted items. The items that were assigned a higher weight were to be more likely to be picked. The following is a JavaScript function that accomplishes Read more…
One common thing that I end up doing, for work and person projects, when writing JavaScript is iterating over all of the properties of an object that I create. Since this task is quite common, I often wrote a each or forEach function for each project. In my most recent Read more…
One thing that I think would be cool is if JavaScript provided a way to pass arguments to a function by name. About two years ago I wrote the code for a Function.prototype.invoke but never released it as part of jPaq like I had hoped. Recently, I decided to re-use Read more…
A few days ago someone asked me how I would go about determining the unicode escape sequence for an arbitrary character. Of course, I went to Google Chrome’s web console and showed them how it can be done by using the charCodeAt, toString, and slice functions. The following is a Read more…
Recently I had to develop a solution which involved changing the HREF attributes of links in the navigation bar of a site. This had to be done on the JavaScript side because at my company we are the 3rd-party JavaScript solution for modifying other companies’ sites. That being said, I Read more…
