flattened icons Although Windows 8 adds a very different start screen, the system's desktop mode does not change except that the Start menu is removed, basically maintaining the style of Windows Vista, the so-called aero glass design. Although this transparent aesthetic style looked great at the time, it is now a bit outdated. Windows 10 has made significant changes to the desktop of the system, including desktop icons, network sett

Thomas Boutell and numerous developers have created a graphic software library known as the GD Graphics library for dynamic graphical computing. GD provides support for many programming languages such as C, Perl, Python, PHP, OCaml, and so on. In addition to generating HTML output, you can use PHP to create and compute graphics files in a number of graphic file formats such as PNG, JPEG, GIF, WBMP, and xpm. Also, the use of PHP allows you to output image streams directly to a browser. To do this

I took the book Java confusing again from the library. Now I want to repeat it again. Unlike reading this book in my junior year, I decided to take some notes. Take some time every day to read some puzzle to make the dull brain clearer. When reading every puzzle in this book, it feels like Fan Wei's Role in the sketch, it is often said that "this is the case ". However, the difference is that reading puzzle makes people smarter, rather than being fooled. So I decided to write a series and read i
