JamochaTrade

I have resumed development of the JamochaTrade project and there has been a lot of progress over the last week or so. The last article left off with a very rudimentary candlestick chart that got its data via cross-domain JSON. I am pleased to announce that a UI has been added, along with the ability [...]

The last article in this series was a bit of a digression into the module pattern and namespaces in Javascript. This article will focus on a very simple charting algorithm. Now that we have the data to draw and know how to move things on the canvas, we need to focus on making the chart [...]

The last article dealt with cross-domain data retrieval. This article will be a short discussion about namespaces and the module pattern in Javascript. Here’s a snippet from the Zen of Python that I think should be included in some theoretical incantation of the Zen of Javascript: Namespaces are one honking great idea — let’s do [...]

In the last installment we successfully created an array of rectangle objects and moved them across the screen. This post will deal with retrieving JSONP data from a different domain. Figuring out how to accomplish this took me longer than I care to admit. I began researching the same origin policy around 14:00 today and [...]

In the last post I used an array to model a rectangle. This worked for a quick test, however the rectangle is probably best modeled as an object. Especially considering that the rectangle is only part of a candlestick bar that also must include a wick, or line. In this part we’ll turn the rect [...]

In the first part of Jumping Into Javascript, we created a simple html page with a canvas element on it and drew a single square. In this part we will concentrate on moving objects that we have drawn. The concept of moving an object on the canvas is a bit of a misnomer. We actually [...]

A few weeks ago I decided to post my first question to stackoverflow… How does a self-taught programmer know when he’s ready to look for a job? The responses I got were very encouraging, but one in particular pointed out some shortcomings in my education. To paraphrase, it instructed me to look around at job [...]
