If you want to create your own desktop or mobile applications (such as HTML5 apps, WebApps, Progressive WebApps, WebExtensions and Hybrid apps), whereas you do not even have any or at least enough programming skills, then you must ask help for some foolproof visual designers to do this. DecSoft App Builder (formerly called App Builder) is such kind of a complete and straightforward visual development environment for Windows.

Ultra Fractal is a full-featured and very fast fractal animation making software developed by Frederik Slijkerman in 1999. It contains thousands of fractal types and coloring algorithms, supports zoom in/out function, uses gradients to add color, and is able to apply multiple layers to combine different fractals in one image - this layering method previously was only found in image editing software.

Computer users who have a little extra money or are willing to cost input on hardware probably have installed and are running their operating systems on a solid-state drive (SSD), in order to gain a better PC performance and user experience. However, SSD has a fatal drawback - it can not write frequently, otherwise the disk life can be significantly shortened. As a result, virtualizing the physical memory as RAM disk became popular. Without exaggeration, RAM disk can be twice as fast as the top-of-the-line SSD and 10 times of the fastest HDD at least!

Kerkythea is a completely free, high-quality and fast 3D models render for Windows, Mac OS X and Linux platforms, developed by Ioannis Pantazopoulos from Greece. I found this free render engine in the process of studying SketchUp (by reading Architectural Design with SketchUp). In the end, it passed the software quality audit of AppNee, thus can be shared with more users around the world. Although it is a free software and not as popular as other renders, the functions of Kerkythea are not inferior in any respect. To some extent, it can be a preferred rendering tool for many small companies.

Now no matter installing Microsoft's Windows operating system or Office software for computer, that can be done directly through Windows Update function. But it's a weakness: always needs Internet connection, and has to redownload all files every time you want to install an update. Therefore, if we can download the offline update files and store them on local drive, then we will be able to use these Windows Update files anytime and anywhere. This is pretty good for system maintainers and IT administrators of companies at least.
