Wohoo! my previous connection was 1Mbs/512kps at most in a lucky day. An stable 3/1 link is too good for me :)

that's over 3G? nice speed in that case! also the latency is very decent considering you're using a server in BsAs!

My new toy doesn't lost packets anymore, doubled the speed of my old connection, and all the goods only because I'm testing the setup in my couch! Can't wait until morning to move it to the roof :)

I wish we had the console recorded too, the video is a bit useless without it. But I guess that's how Hangouts on air records work...

I am testing the router+3G modem at home w/o external antenna.
~50% packet loss and 6 seconds avg ping time. Not great huh?

--- google.com ping statistics ---
86 packets transmitted, 46 packets received, 46% packet loss
round-trip min/avg/max = 138.635/6062.452/21705.104 ms

I'm glad I spent past Saturday improving the thermal isolation of my roof, the sun is at its maximum radiation and it's currently 35 °C outside.

A lot cheaper than I initially thought, it was USD18 per m² including materials and manpower.

Very clever use of GIF movies created by uploading similar photos to G+. Bookmarked for my TODO.
 
I thought this might be relevant to the interests of the archlinux|arm G+ community since it uses both arch arm and G+.  I recently set up a few security cameras around the house and picked up a Raspberry Pi and installed arch on it to manage them.  

Whenever there's movement detected, the cameras upload photos to the Pi through FTP.  I use a script to add the black borders so that it meets the size requirement for G+, add exif data for date/location, and sort by which camera it comes from.  Then grive (https://aur.archlinux.org/packages/grive/) syncs the pictures with my google drive since there's still no official Linux client.

Google+ then does a decent job of sorting pictures for significance since there's a lot of plain shots of my doors.  Auto awesome also makes nice gifs of any motion.

All in all I'm very impressed by archlinux|arm - packages build with relative ease and everything works just like I expected.

Yes, it is. It is a YAGI antenna designed for Movistar 850Mhz.
