The Electronic Frontier Foundation's staff technologist Peter Eckersley writes in "Why We Need An Open Wireless Movement" about the positive aspects of sharing your WiFi with your neighbors and passers-by and about the tragedy of the commons that is puts those of us who generously share our networks with the world at risk. He proposes future direction for protocol and hardware design that allow us to share while keeping our traffic private and while maintaining a minimum amount of bandwidth for our own use.
The problem that's really killing open WiFi is the idea that an unlocked network is a security and privacy risk.

This idea is only partially true. Computer security experts will argue at great length about whether WEP, WPA and WPA2 actually provide security, or just a false sense of security. Both sides are partially correct: none of these protocols will make anyone safe from hacking or malware (WEP is of course trivial to break, and WPA2 is often easy to break in practice), but it's also true that even a broken cryptosystem increases the effort that someone nearby has to go to in order to eavesdrop, and may therefore sometimes prevent eavesdropping.
It doesn't really matter that WiFi encryption is a poor defense against eavesdropping: most computer users only understand the simple message that having encryption is good, so they encrypt their network. The real problem isn't that people are encrypting their WiFi: it's that the encryption prevents them from sharing their WiFi with their friends, neighbours, and strangers wandering past their houses who happen to be lost and in need of a digital map.

A group of computer scientists from Tsinghua University, Tencent and Tsinghua National Laboratory for Information Science and Technology have posted a first-of-its-kind paper to Arxiv, analyzing the problems that make connecting to wifi networks so achingly slow.
Randal Munroe nails it again in an XKCD installment that expresses the likelihood that your houseguests will be able to connect to your wifi (I confess to having been the “firmware” guide — but also, having been reminded to do something about my own firmware when other difficult houseguests came to stay).
Germany’s ruling coalition is modifying the country’s legal “Störerhaftung” theory, which currently makes people liable for copyright infringement if they operate an open wifi network that someone else uses for copyright infringement, even if the operator didn’t and couldn’t know about it.
Bamboo has lots of uses beyond just being panda food. Things like bikes, roads, scaffolding, and musical instruments are made from the fast-growing grass. But unless you are participating in a tropical-themed LARP, you probably wouldn’t want a shirt made from bamboo stalks. So why do bamboo bed sheets make any sense? Because yarn extracted from […]
If you want to work in tech, but don’t have any desire to code web apps to help businesses sell things to other business, you might want to consider a career in cybersecurity. Judging from the apparent complete infiltration of Russian hackers in American cyberspace, it seems fair to speculate that there’s a major shortage of […]
All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
