Minneapolis radio host said Code Pink protesters "ought to have all their tubes tied"
On the September 5 broadcast of his Minneapolis radio show, host Chris Baker asserted that the Code Pink protesters who interrupted Sen. John McCain's acceptance speech at the Republican National Convention on September 4 "ought to have all their tubes tied." Baker stated of McCain's speech, "I'll tell you, though, in the speech -- the best part of the speech was when those Code Pink nuts -- another bunch that ought to have all their tubes tied. All right? I can't stand these Code Pink broads." Code Pink describes itself as "a women-initiated grassroots peace and social justice movement working to end the war in Iraq, stop new wars, and redirect our resources into healthcare, education and other life-affirming activities." The Chris Baker Show airs on Minneapolis' 100.3 KTLK-FM, owned by Clear Channel Communications. From the September 5 broadcast of 100.3 KTLK-FM's The Chris Baker Show: BAKER: I'll tell you, though, in the speech -- the best part of the speech was when those Code Pink nuts -- another bunch that ought to have all their tubes tied. All right? I can't stand these Code Pink broads. CO-HOST: Uh, that's "chicks." BAKER: Oh, I'm sorry. These -- OK, "these stupid Code Pink chicks."

Miraculous radio-controlled milking-machine of 1931
With only a five-foot length of copper, it was possible for the farmer of 1931 to milk his cows by radio control! THERE seems to be no end to the versatility of radio in these days of electrical and mechanical miracles?not even cows and street cars are immune to the influences of its radiations. As a curtain raiser at the annual radio show held recently in St. Louis, a street car was operated from a distance by a mere man with a radio transmitter in his hand, and a Holstein cow was made to dispense her milk by the medium of radio waves, whether she liked it or not. The mechanism of the trolley car and the mechanism of the milking machine were hooked up to a specially constructed radio receiver using only a five-foot length of copper pipe as an antenna. At a distance stood the operator, holding a portable radio transmitter using a similar antenna, as shown in the accompanying photos. When the key was pressed at the transmitter, the distant receiver in both cases set the machines to operating. Radio Milks Cows, Runs Street Cars (Feb, 1931)...

Radio that's all user-interface
Here's a radically simplified user interface for a radio -- as Kottke says: The Hidden Radio has no obvious controls...unless you count that the radio *is* the controls...it "has either no user interface...or...is all user interface". The volume is controlled by lifting the lid of the radio (which also reveals the speaker). Tuning is done by twisting the lid. Absurdly clever. Hidden Radio (via Kottke)...

Radio news host among protesters arrested at RNC for "conspiracy to riot", National Guard headed in?
Amy Goodman, host of the independent news program "Democracy Now!," was among hundreds who were arrested in St. Paul Minnesota today. Also detained were Goodman's producers, Sharif Abdel Kouddous and Nicole Salazar. The three were covering the protests at the Republican National Convention, but the Minneapolis Police Department charged them with conspiracy to riot. Goodman has since been released, but her colleagues are still being held at the time of this blog post. Video embedded above from Rick Rowley and Brandon Jourdan. Democracy Now's news release about the incident is here. (via @kenyatta) More on the story: Editor and Publisher, San Francisco Chronicle, and Washington Post, snip below: "I was down on the convention floor interviewing delegates when I heard that two of our producers had been arrested," said Goodman. "I ran down to Jackson and 7th Street, where the police had moved in." Goodman said that when she ran up to find out what was going on, she was also arrested. "They seriously manhandled me and handcuffed my hands behind my back. The top ID [at the convention] is to get on the floor and the Secret Service ripped that off me. I had my Democracy Now! ID too. I was clearly a reporter." Goodman, who was released after being charged with a misdemeanor, said that Salazar had been hurt in the face, while Kouddous had been thrown up against a wall and hurt his elbow. "Nicole told me that as they moved in on three sides, she asked them 'How do I get away from this?' and they jumped on her." Update: A group called Cold Snap Legal in the Twin Cities area is offering legal assistance to the hundreds of protesters who were arrested today at the RNC. Here's their Twitter stream, with lots of updates (thanks, Kyle). Via that Twitter stream, a re-tweet from @tcdailyplanet, 830pm PT: "Credible report of a convoy of National Guard heading toward the Twin Cities on Highway 55 between 8 and 9 p.m., with at least 7 humvees." Previously on BB: Report: Massive, warrantless raids on peace protesters in Minneapolis, ahead of RNC....
