A word of warning: Google for the definition of the word “pummer” at your own risk. Rest assured that this beautiful solar-powered circuit sculpture fits the only definition of pummer that we care to deal with.
For the unfamiliar, a pummer is a device from the BEAM style of robotics, …read more

Cryptocurrencies: love them, hate them, or be baffled by them, but don’t think you can escape them. That’s the way it seems these days at least, with news media filled with breathless stories about Bitcoin and the other cryptocurrencies, and everyone from Amazon to content creators on YouTube now accepting …read more
In the radio business, getting the high ground is key to covering as much territory from as few installations as possible. Anything that has a high profile, from a big municipal water tank to a roadside billboard to a remote hilltop, will likely be bristling with antennas, and different services …read more

Orbiting hunks of metal make it possible for billions of earthlings to benefit from marvels of the digital age, from GPS signals and weather monitoring systems to the communication protocols for credit card authorizations and other complex transactions. Humans take these satellite connections for granted, but new research suggests we’ll need to take important steps to keep it way. As of January there were at least 1,957 satellites in orbit, according to the Union of Concerned Scientists, some of which are vulnerable to various levels of snooping and disruption, including jammed communications, data interception, data hijacking and outright takeovers. The issue is especially urgent now because of the coming wave of connected devices and the evolution of 5G cellular networks, said Bill Malik, vice president of infrastructure technologies at the security vendor Trend Micro, who presented research on satellite security Wednesday at the RSA cybersecurity conference. “We didn’t think about this much until the popularization of […]

Did you know Britain launched its first satellite after the program had already been given the ax? Me neither, until some stories of my dad’s involvement in aerospace efforts came out and I dug a little deeper into the story.
I grew up on a small farm with a workshop next to the house, that housed my dad’s blacksmith business. In front of the workshop was a yard with a greenhouse beyond it, along one edge of which there lay a long gas cylinder about a foot (30mm) in diameter. To us kids it looked like a torpedo, and I …read more

For David Cowan, the tipping point was a cyberattack from Anonymous. Cowan, a venture capitalist at Bessemer Venture Partners, had spent years asking startup founders what they planned to do if hackers targeted their business. Often, the founders on the other side of the boardroom would shrug and say, “We don’t hold any personal information, so they don’t need to come after us.” That changed, he said, after the email marketing company SendGrid was hit in 2013 with a denial-of-service attack that ultimately caused about 20 percent of the young company’s clients to walk away, not too long after Bessemer had led a $21 million funding round for the company The attack occurred after an employee, Adria Richards, publicly complained that a developer from the gaming company Playhaven made sexual remarks in the audience at the 2013 PyCon tech conference. Playhaven fired the employee, infuriating an online mob that sent Richards death threats. Anonymous got involved too, […]

How hard is it to build a ground station to communicate with people via a satellite? Probably not as hard as you think. [Modern Ham] has a new video that shows just how easy it can be. It turns out that a cheap Chinese radio is all you need on the radio side. You do, however, benefit from having a bit of an antenna.
It isn’t unusual for people interested in technology to also be interested in space. So it isn’t surprising that many ham radio operators have tied space into the hobby. Some do radio astronomy, others bounce signals …read more
There are a number of layers that need to be secured. There’s the network layer, for which we have Tor and other anonymizing applications and the physical layer. I don’t see how one can be concerned with network security, but… Continue reading What’s the most anonymous way of severing IP from actual physical location?

The entirety of Silicon Valley is predicated on the ability to ‘move fast and break laws’. Have an idea for a scooter startup? No problem, just throw a bunch of scooters on the curb, littering and e-waste laws be damned. Earlier this year, Swarm Technologies launched four rogue satellites on an Indian rocket. All commercial satellite launches by US companies are regulated by the FCC, and Swarm just decided not to tell the FCC. This was the first unauthorized satellite launch ever. Now, Swarm has been fined $900k. Now that we know the cost of launching unauthorized satellites, so if …read more
