A Column definition class which renders color. I have used Ext.ux.colorpick.Field. Nothing special, just extended the ‘Ext.grid.column.Template‘. It is also possible to implement using widget column nut I prefer the simplest way always.

Edge date picker bug in modern toolkit > v7.0
Edge date picker of ‘Ext.field.Date‘ is generally used on small form-factor devices. However, bug happens when you use multiple date fields. It was described by RC on stack-overflow and it took a bit more time for me to fix it.
Mandelbrot Set
Mandelbrot Set/Fractal with Vanilla JS. Here I used web workers to move the fractal calculations to a separate thread. Currently, web workers is not being used in most projects, but I am sure the multithreading web applications and appropriate frameworks of web workers has potential to be used in the future.
I am against the idea of using vanilla js in the middle of a huge project because sooner or later, developers will have to create their own framework which will not only drastically increase the time of developing a project but it will also make the application more unstable. Anyway, since frameworks and libraries can make us lazy we sometimes need to develop something small in raw javascript so we do not to lose skills and are challenged to go out of our comfort zone.
Editable grid with multiSelect combobox in column editor
This post is about an editable grid with editable multi-select combobox. This solution is for extjs 4.2. In the newer versions (>= v5.1) the ‘multiSelect’ property is deprecated. If you do not want to have problems during your framework upgrade in the future, I would suggest not to use the deprecated functionality and use the tag field.
