Pinouts from ESP8266 Boards I Bought Recently
I bought some cheap ESP8266 dev boards from ebay sos I can easily code on them without having to breadboard a programmer. I build a programmer, lost it, and these are cheap. Instead of having to build a new one I ordered these while I was out of town and they were waiting for me… which is nice.
Breadboard style:
Arduino style:
I'm sure these might be from some other design from a non-ebay seller, but I haven't really found them yet. Until I find those docs, I'll just use these.
GNOME 3, Surface Studio Display Issues
TL;DR: This is unsolved. I need GNOME to either ignore different “monitors” and treat all connected displays as a single display, or I need it to honor xrandr –setmonitor settings. It is possible that by hand hackery of monitors.xml would accomplish this, but I don't know the schema well enough to say if it would work.
GPIO on Arch Linux ARM for Raspberry Pi 3 (aarch64)
While everyone appears to prefer that you don't, performance is a bit better on 64bit ALARM vs. 32bit for what I'm doing. Also, I get that warm, tingly feeling of running upstream kernel without odd Broadcom or RPi Foundation patches.
That said, a lot of the basic stuff for managing GPIO isn't available. I had to poke for a few days to figure out what's going on, so I thought I'd document it, partially to save other people time, and partially so it's all in one place when I get back to it.
Anyway.
Simpler internal bridge for Xen on Arch using netctl
Just change 'Interface' and 'Dummy' appropriately, and you'll have a nice internal bridge for VMs without having to vswitch things.
Description='internal bridge for xen'
Interface=in0
Dummy=dummy0
Connection=bridge
IP=no
IPCustom=("link add $Dummy type dummy"
"link set $Dummy up"
"link set $Dummy master $Interface")
