I too got sick of trying to make a clean samba experience (Windows to Raspbian). I finished up with this smb.conf, and I am now content.

Re: issues with samba shares on raspbmc

I have found that recent debian versions (Raspberry Pi included) have some problems doing rename and delete functions by a samba connection. The permissions that allow read and write access and file creation seem to not be what is used for delete and rename. It drove me crazy. On rPi and on mint LMD...

Re: RPi running VNC Client

I've run remmina on a Pi. It was straightforward enough.

(It was actually controlling a second Pi. The 2nd Pi was headless, with both x11vnc on :0 and tightvncserver on :1.)

Bootstrapping the Pi: USB-ImageWriter

For burning a new SD image, Windows users have their Win32DiskImager. Linux PC users, depending on their distribution, have the equivalent USB-ImageWriter. (So why do all the howto's only describe making SDs in linux with dd?) And USB-ImageWriter works fine on the raspbian version of Pi, provided yo...

Got a couple of Meduino Nano boards from eBay at under $12 each recently. They make a great IO board with 17 I/O pins, some analog. The Meduino has a 5V/3.3V switch, allowing its I2C to work with the rPi "cost free" (no rPi pins as I was already using i2c, no level converter). The Meduino is very sm...
