I've had the 1980's awk book seemingly "forever", but use awk so infrequently I always need to look things up.

It's nice to see what could have been... Mine suffers from a lack of connectivity, can't even use it on Wi-Fi without constant disconnects.
My previous keyboard phone was Nokia N900 which was incredible, if a bit small. I find the Pro1x to be too large for my hands, a phone about 4.5 or 5" would be ideal.
Cognex Barcode Scanner is not open source but it is the best. It's basically just a demo frontend for a commercial barcode programming library so they are not trying to monetize the app itself. It supports everything! Not just QR code but every kind of barcode. I used to work in logistics and I used it to scan all the different barcodes on shipping labels.
When you scan a barcode you can choose to open, copy, share. Open launches your default web browser. If the barcode isn't a URL, it all give a search option and you can configure your preferred search engine. It can scan images from your gallery or use your camera. But the important part is it won't do anything with the scanned data until you tell it to.
Nice! I'm jealous.
Even using Wi-Fi in my house, it constantly drops connections. I was hoping to use it to basically VNC to my desktop but it is so slow and disconnects constantly. There's some speculation that some of the antennas were not soldered properly or something like that.
Mine also has large black dead spots in the bottom corners of the screen, seems like it was over tightened during manufacturing. Maybe that's also what broke the antenna!
Theoretically they are supposed to have an adversarial relationship with the Congress and the president, but...
