Raspberry Pi configuration software source

Raspberry Pi Foundation, a separate (non-Raspbian developers) to provide software source / maintenance, including raspi-config, minecraftpi, raspberry pie desktop environment, a small amount of kernel firmware, drivers and other software.
The software source relevant information is relatively small, the country currently only have Qinghua (201709 began offering) and has provided USTC

#### Stretch (Tsinghua selected source line)

HTTPS the deb: // mirrors.tuna.tsinghua.edu.cn/raspberrypi/ Stretch main UI 
deb- the src URL # same as above

# ' Deb-src ' default to download the software source code along with Raspberry Pi 
# ' deb-src ' without also   
#### Jessie 
deb HTTPS: // mirrors.tuna.tsinghua.edu.cn/raspberrypi/ Jessie main ui

raspbian this source by independent developers to maintain, there is no direct contact with the Raspberry Pi Foundation. More domestic sources, or to select a minimum velocity is preferably connected to the physical distance or the shortest delay themselves.
