NextDoor and silos

Searching around this morning, I found this insightful comment on NextDoor which echoes my concerns. It was posted on a message board way back in October 2011:

How tragic that I could sign up to *heyneighbor.com* and *not* be connected to all my neighbours who happened to signed up to *nextdoor.com* And every new venture in this space could serve to silo people as much as it connects them. These business models contain paradox – they can only succeed in a neighbourhood if they have a monopoly.

There’s a lot of truth here.

Are all telephone calls recorded and accessible to the US government?

In addition to collecting call detail records, there is some speculation that phone conversations themselves are being harvested. Recall this exchange from last month, as reported by Glenn Greenwald of The Guardian:

On Wednesday night, Burnett interviewed Tim Clemente, a former FBI counterterrorism agent, about whether the FBI would be able to discover the contents of past telephone conversations between the two. He quite clearly insisted that they could:

BURNETT: Tim, is there any way, obviously, there is a voice mail they can try to get the phone companies to give that up at this point. It’s not a voice mail. It’s just a conversation. There’s no way they actually can find out what happened, right, unless she tells them?

CLEMENTE: “No, there is a way. We certainly have ways in national security investigations to find out exactly what was said in that conversation. It’s not necessarily something that the FBI is going to want to present in court, but it may help lead the investigation and/or lead to questioning of her. We certainly can find that out.

BURNETT: “So they can actually get that? People are saying, look, that is incredible.

CLEMENTE: “No, welcome to America. All of that stuff is being captured as we speak whether we know it or like it or not.”

NSA collecting phone records of millions of Verizon customers

Yesterday it was revealed that the National Security Agency is collecting millions of phone records from Verizon:

The National Security Agency is currently collecting the telephone records of millions of US customers of Verizon, one of America’s largest telecoms providers, under a top secret court order issued in April.

The order, a copy of which has been obtained by the Guardian, requires Verizon on an "ongoing, daily basis" to give the NSA information on all telephone calls in its systems, both within the US and between the US and other countries.

The document shows for the first time that under the Obama administration the communication records of millions of US citizens are being collected indiscriminately and in bulk – regardless of whether they are suspected of any wrongdoing.

Today, the Wall Street Journal claims this extends to AT&T and Sprint customers, too. Yesterday, The Guardian revealed PRISM, a Top Secret NSA program to directly query social media servers owned Facebook, Google, Apple, and others.

I suppose the idea of “innocent until proven guilty” got left behind somewhere in the 20th century.

Renewable energy is clean, cheap and here – what’s stopping us?

Great article on the solar revolution.

Solar will be the cheapest form of power in many countries within just a few years. In places such as California and Italy it has already reached so-called “grid parity.” Onshore wind, on a piece of land not constrained by years of planning delays, is already the cheapest form of energy on earth. These are not wild claims – those are figures from General Electric, Citibank and others.

Newly built solar plants are already considerably cheaper than new nuclear plants per kilowatt hour of electricity produced and we are almost at the stage where we don’t need a guaranteed price known as a feed-in tariff because solar energy will compete head on with conventional energy.
