Adafruit has created a handy how-to to help you build a wireless access point that anonymizes your internet browsing using Tor and a Raspberry Pi.
- The bottom-left point about geolocating routers is fascinating, considering costs and speed but how ‘fixed’ are routers given their shoddy shelf-life?
- For those who don’t password-protect their wifi signals, I’m curious if there’s a change in content captured and if *google* would be curious about it (also, wouldn’t it be polluted by neighboring freeloaders?)
The real failure of infrastructure here has actually very little to do with technology. It’s easy to mock Homeless Hotspots; it’s easy to disdain it; but, really, what would we prefer, the typical combination of ignoring and ignorance that we reserve for most of our dealings with the hundreds of thousands of people who are homeless in the U.S.? BBH is taking a bad situation — the fact that Austin has people who lack homes and jobs and who, given the choice, would prefer to have both — and trying to do something constructive with it. Yes, it’s gimmicky; yes, it’s weird; yes, it’s initially kind of offensive. It’s right that our gut reaction to Homeless Hotspots is disbelief and disgust; it’s right that we’re alarmed at the idea of turning people into platforms. It’s also right, though, that we take the next step to ask ourselves: What’s the alternative? That we go on ignoring homelessness? It’s nice to be reminded that Austin, even in March, is about more than serendipity apps and rooftop pool parties. […]
Yes, there are ironies to it. Yes, there are hypocrisies to it. But they’re ironies and hypocrisies that we should be talking about, rather than outrage-ing and indignation-ing and then moving on. If we’re appalled at the idea of Homeless Hotspots, great. But perhaps we should be directing our indignation at “homeless” rather than “hotspot.”
New research could lead to 1,000x faster wireless data transfers.
Researchers at Pittsburgh University have found a way to modulate light in the terahertz bandwidth (THz, or 1 trillion cycles per second), with recorded frequencies of up to 15.6 THz.
With current generation wireless routers and networks working around speeds of 5 GHz (1 GHz = 1 billion cycles per second), the demonstration could one day lead to Wi-Fi networks well over a thousand times faster than current speeds.
To achieve the modulation, the team created a ‘frequency comb’ able to divide a single colour of light into a series of evenly spaced spectral lines spanning a more than 100 terahertz bandwidth by exciting a coherent collective of atomic motions in a semiconductor silicon crystal.
The team is already investigating the coherent oscillation of electrons, which could further extend the ability of harnessing light-matter interactions from the terahertz- to the petahertz-frequency range. Petahertz is another 1,000 times faster than terahertz.
