RadBuilder is an excellent RAD (rapid application development) tool with a fully visual integrated development environment (IDE). It is primarily used to quickly create interactive multimedia applications, database applications, and Web applications for Windows, without writing any code. It is so easy to learn and use that it can be picked up quickly by beginner developers without any programming experience.

When we are in the early stages of any kind of projects (e.g.: novel writing, software development, project discussion), we probably tend to put a bunch of ideas on a big piece of paper, then throw out the irrelevant ones, group together the relevant notes, and make connections between them, so as to figure out how everything fits together.

Luminar is a rising full-featured image post-processing software for Windows and Mac, developed by Skylum (formerly called Macphun) in 2016. It is similar to Adobe Lightroom in functionality, and is more convenient and easy to use than Adobe Photoshop. In just a few years, it has become the most popular photo editor for photographers.

The most popular graphics/image processing programs on Linux platform are: GIMP, Inkscape, and Dia, each of which has its own unique functions. Thereinto, GIMP claims to be the Adobe Photoshop for Linux; Inkscape claims to be CorelDraw for Linux; while Dia refers to Microsoft's Visio. Here, we recommend Inkscape to you all.

I have loved listening to the radio since I was a child, from FM (Frequency Modulation) to AM (Amplitude Modulation) and SW (shortwave). The content ranges from my favorite domestic programs to foreign ones that I totally don't understand at all (in that case, of course, they are mostly music related programs). This habit continued until we could listen to more Internet radio stations with better sound quality more easily on our computer. After that, listening to radio programs on a semiconductor/digital radio has become a beautiful memory of the past forever.
