Recently feel the use of mobile hard disk backup Mac computer is very inconvenient, because to take out the mobile hard disk, but also plug in the computer backup, looked at airport, but the price is too expensive, and can only be used for Mac backup and can not be used for other samba services, etc., feel less cost-effective, So I'm going to do a timemacheine and samba service, the Timemacheine service is used primarily for Mac backups, and samba is used to store some files on computers in the

same as the previous cont. routines, Ssh+vnc. Now the small partners, whether it is the network cable straight, or WiFi hotspot we are connected to small pi, in order to later we can the small Pi overlord the bow, we have to prepare some tools--ssh and VNC. reason: ssh+vnc simple rough Connection Small pi Brief Intro

If you want to use Raspberry Pi as a small server, the performance may be poor, but the stability must be ensured. The following describes how to improve the stability of Raspberry Pi on the network. 1) modify it in/etc/sysctl. confVM. min_free_kbytes(8192 to 16384) # RPI tweaksvm. swappiness = 1 # VM. min_free_kbyt

Look at build 2015 in the middle of the night, basically heard 3, 4 times "Raspberry Pi", but always did not demonstrate win10 in the RPI above what kind of, so ... Try it yourself. First the pit is DISM: see an Ffu file, read the instructions, that is DISM directly deployed to the SD card. So is it possible to use LINUX+DD? Try it, no ... Then using win8.1 for DISM, found error 87, go back to look at the
