If you're one of the poor souls who bought a 800x480 Waveshare 7" HDMI touchscreen (revision B), there's a special edition of Privacy Enhanced Linux with a custom touch driver. The new rev C version which is a higher 1024x600 resolution apparently works with the standard HID driver so this isn't needed. The 1.9 gigabyte microSD card image is here:

It's also a preview of the next version of PELinux. English to Spanish translation engine and text to multilingual speech are working quit well. I screwed up the firewall setting for Internet radio by accident though... must have switched to/from on the command line. To correct, click the firewall icon, enter "pi" as the keyring password, click the unlock button, then scroll down to where "Anywhere" is in the "To" (left-most) field. There should be two entries -- one at the end of the IPv4 list and one at the end of the IPv6 list -- delete them both by highlighting and clicking the minus button. Lastly open a terminal window and execute:

sudo ufw allow proto udp from any to any port 6799:6999,8000:8499

That'll open up the 200 most common ports and an additional 500 used by some others. If you want to hear death metal radio on port 666 use above example, just change numbers at the end.
