This is a long review about the new deepin 15.3 GNU/linux operating system . deepin 15.3 released 13 September 2016 bringing a very beautiful desktop plus so many new features we excited to see. I consider now that deepin 15.3 desktop is one of the most beautiful GNU/Linux desktop systems ever made , besides the elementary OS Loki, and at the same time is also extremely useful in desktop features (except its inclusion of proprietary software). I divide this review in 9 parts, with 3 additional parts, and 1 bonus in the end. I hope this review will be useful a lot for everyone.

i. About Deepin
GNU/Linux Review: deepin 15.3
deepin is a free GNU/Linux software distribution from Wuhan Technology , a Chinese commercial company focused on R&D. A deepin GNU/Linux distribution product consists of the operating system itself, the software, and the repositories. Deepin OS is designed for desktop usage with its own user interface called Deepin Desktop Environment ( DDE ) and daily-usage desktop software such as Deepin File Manager , Deepin Screenshot , Deepin Store , and many more. Deepin itself is a derivative of Debian GNU/Linux, which makes use of the same dpkg/apt management system.

For deepin 15.3, these are the basic information:

Architecture: 32 & 64 bit ISO size : 2 GB & 2 GB MD5 hash sums : 90404d0929499e652f373bfae9f07b41 and c52c6d309f311346e996aa82a34af286 Type : desktop only Derived from : Debian sid Download : https://www.deepin.org/download.html Source code : https://github.com/linuxdeepin Price : gratis License : free software & open source (with some proprietary software component) Minimum requirements : Intel Pentium 4 (or anything else comparable) processor, 1 GB of RAM ii. Memory Consumption

deepin 15.3 consumes around 400-500 MB of RAM when idle in my laptop (natively installed in an external HDD). It is already huge for desktop computers, but it is still lower thanelementary OS Loki that consuming around 600-700 MB when idle.

a) RAM Usage

It eats around 519 MB of memory when idle in my laptop. So I can not recommend 512 RAM computer users to install deepin, because at least you will need 1 GB of RAM (but it will be a pain), rather, I recommend you to have at least 2 GB of RAM to install deepin.

b) Huge Processes

As you can see at running process list below (taken while it's idle), the most consuming process is deepin-wm with 34 MB usage of RAM and the "runner-up" is dde-launcher with 30 MB usage of RAM. Again as you can see, deepin as desktop OS, spends especially many memory on the desktop user interface. I recommend anyone to install deepin 15.3 in computer with RAM at least 2 GB.

iii. Shortcut Keys

deepin desktop has its own shortcut keys scheme. It has some different points from any other desktop environment in GNU/Linux. If you don't know, Super key is windows key in most keyboards, a key placed usually between Ctrl and Alt keys.

Super : show desktop menu (launcher). Super+S : activate multitasking mode. Super+D : show desktop or maximize all windows. Super+W : spread window. Super+E : open Deepin File Manager. Alt+Tab : switch between windows. Ctrl+Alt+T : open Deepin Terminal. Super+Up/Down : maximize/minimize window. Ctrl+Alt+A : take screenshot (whole desktop or region). Alt+PrintScreen : take screenshot of current window. Ctrl+PrintScreen : take screenshot with delay time. Terminal: Ctrl+Shift+J : vertical split. Terminal: Ctrl+Shift+H : horizontal split. Terminal: Alt+H/J/K/L : select a split window. Terminal: Ctrl+Alt+Q : close a split window. Part 1: Desktop

deepin user interface is an integrated software stack called Deepin Desktop Environment (or simply DDE ). It has a very different design compared to any desktop environment available for GNU/Linux . The most noticeable appearance of DDE consists of 3 aspects: the bottom dock , the right sidebar , and the desktop menu .

1.1 Desktop Menu

deepin DDE menu can be accessed by pressing Super key (Windows key, keyboard). It is the same behavior as Microsoft Windows desktop menu, and also Unity's, and GNOME's menu. While opened, the menu covers the display up, showing application icons plus a search bar.

1.2 Desktop Menu (Alternative)

While we point the cursor into the top-left corner, and click the button, we can change the icons arrangement with the categorized style (alternative). It groups the icons into categories, to help new users differentiate between them. Click it once again, the icons arrangement goes back to default. It's a new thing for desktop menu to place the categories list in the left and using horizontal lines to separate the icon groups.

1.3 Dock

The first thing to notice from deepin DDE is the bottom dock. It reminds us to Apple MacOS style, but without the top panel on the desktop.

1.4 Dock (Alternative)

Also, it reminds us to elementary OS style. The most different thing between DDE's one and them is that DDE dock is changeable into a fully-horizontal bottom panel (taskbar). If you look at this picture below, you will notice that this style is very similar to Windows 7's or 10's taskbar. It has the task switcher, a system tray, and also place for docked icons. If you like the time always shown, then this alternative style is the best.

1.5 Wallpapers Because it has no window for System Settings (explained in next part below), deepin has its own style to change desktop wallpaper. It has an on-the-fly wallpaper changer, a bottom panel with wallpaper pictures, when the user a
