Part I: Building Broadband Absorber Panels
Background:
After reading Ethan Winer’s articles and information from Auralex Acoustics, RPG , Jon Risch’s great DIY site and the enlightening Ethan Winer: Acoustics Forum at Music Player Network, I decided to build a modified version of the 703 2’x4’x4” panel bass traps and then two “Super Chunk” Corner Bass Traps. Initially for the panel traps I planned to build a wooden frame as others have done.
But after reading Ethan’s “Real Traps – Measuring Absorption and the Numbers Game” article I decided to attempt a design more resembling the Real Traps frame. My goals were to build a light yet strong frame and to simultaineously maximize the amount of absorption on the 4” sides of the trap by not using a solid wood frame. Of course at a DIY project I also wanted to to build the traps as cheaply as possible.

90-Percent of SF Cocaine Cut with Animal Deworming Medication – SFist
According to San Francisco General Hospital, 90-percent of all patients who’ve tested positive for cocaine use have also tested positive for the animal deworming drug levamisole.
U.S. health officials first warned of the drug in September and the CDC just reported that 69-percent of all cocaine seized in the U.S. is tainted with it. While cocaine is often cut with other drugs to both increase its weight and potency, officials don’t know why levamisole is being used.
The drug can cause agranulocytosis, which significantly reduces the number of white blood cells in the body causing fever, swollen glands, and painful sores around the mouth and anus. And women seem to be more affected by levamisole than men are.
“If 90 percent of cocaine users in San Francisco are positive for levamisole and are being exposed to this compound, then why aren’t 90 percent of them in the emergency room with these side effects?” asks Kara Lynch, associate chief of the chemistry and toxicology lab at S.F. General.
Oddly enough, San Francisco patients are experiencing a condition that others are not: their skin is turning black! Dr. Jonathan Graf, an assistant professor at S.F. General says their skin appears to be “sloughing” off. He feels that there are other cases of this happening but that people just aren’t going to see doctors about it.
It’s worth noting that the drug levamisole was found in DJ AM’s body along with cocaine, OxyContin, Hydrocodone, Vicodin, Xanax, Ativan, Klonopin, and Benadryl. The entertainer died of an overdose three months ago.

Pot legalization almost certainly headed for California ballot | Raw Story
Voters in California will likely decide this November whether or not to legalize marijuana, after legalization activists handed in far more than the necessary number of petition signatures to get the measure onto the ballot.
Organizers of the Regulate, Control and Tax Cannabis Act of 2010 filed some 700,000 petition signatures with county clerks around the state. The amount of signatures needed to get the measure on the ballot is about 433,000, reports the San Francisco Chronicle, so the measure is all but certain to be on the ballot in November.
If California voters approve, it will be the most comprehensive reform of marijuana laws ever undertaken in the United States. While some states, such as Oregon, have relatively lax penalties for possession, no state has attempted to regulate and tax the herb before.
The measure’s chances are good: A poll taken last April found that 56 percent of Californians want to see the herb legalized and taxed.
According to the L.A. Times, the measure would make it legal for anyone over 21 to own an ounce or less of pot, and to grow pot for personal use in a space no larger than 25 square feet. It would also give cities the right to license marijuana growers and sellers, and to collect taxes on the crop.

The Strangest Guinness World Records (PHOTOS)
It often seems like every week there is news of someone setting, or breaking, the Guinness World Record for some dubious achievement on which you never even believed people would have thought it fit to bestow commendation. (This week’s example being the man who broke the yo-yo world record, though in his defense that at least required some technical skill.)
And so, in honor of the Guinness World Records’ tireless support of novelty achievements, we’ve rounded up 13 of the strangest, and occasionally pointless, records (so many to choose from!) for your amusement. Think we’ve unfairly neglected something truly superfluous? Let us know.

Halliburton/KBR Attacks Employee Gang-Raped On Their Watch | Women’s Rights | Change.org
How is being gang-raped by colleagues a legitimate “distinct risk” of working for a defense contractor?
I’m sure you’ve heard the story of Jamie Leigh Jones, the Halliburton/KBR employee who was drugged, gang-raped, and abused by her coworkers while in Iraq, and then locked in a shipping container and threatened by the company in an attempt to zip her mouth shut. KBR’s rape-permissive environment left the men so confident that they wouldn’t be punished, one didn’t even bother leaving and was still in Jones’ room when she awoke, mutilated and violated.

List of United States politicians who admit to cannabis use – Wikipedia, the free encyclopedia
Cannabis is a genus of flowering plants with species that have long been used for fiber (hemp), for medicinal purposes, and as a recreational drug. Industrial hemp products are made from cannabis plants selected to produce an abundance of fiber and minimal levels of tetrahydrocannabinol, a psychoactive molecule that produces the “high” associated with marijuana. For more than half of the history of the United States cannabis was used primarily for industrial purposes, and at times was even required by law to be grown out of “strategic necessity”. Domestic production continued until after the Civil War, while marijuana remained a common ingredient in medicines up to the 20th century. Following immigration caused by the Mexican Revolution, recreational use of marijuana became widespread, resulting in political pressure to enact a federal ban of cannabis. While the attitude of the general public towards marijuana has changed throughout the history of the nation, today cannabis remains classified as a Schedule I drug under the Controlled Substances Act, and possession is punishable by up to one year in jail and a minimum fine of $1,000 for a first conviction.
Prior to prohibition, U.S. politicians known for growing cannabis include some of the nation’s Founding Fathers and Presidents. Politicians that have admitted to recreational use following prohibition include mayors, Governors, members of the House of Representatives, Senators, and Presidents.

iPhone SDK updated: VoIP over 3G now permitted
It’s been a long time coming, but the last hurdle is gone — Apple has lifted the restrictions against 3G VoiP calls from the iPhone Software Development Kit.
The implications of this are pretty huge. Not only does this mean that VoIP apps like Skype [iTunes Link] can now be easily updated to allow VoIP access over 3G on the iPhone, it also means that the 3G-enabled versions of the new iPad should be able to take full advantage of VoIP over 3G as well. The iPad does come with a microphone and a speaker, so while you won’t be able to hold the device up to your ear like a phone (although it would be pretty funny to watch you try), calls over Skype or another VoIP program should theoretically be just as clear on the iPad as they are on the iPhone’s tiny speaker. This has the potential to really shake up the wireless industry, especially in the U.S. — with pay-as-you-go 3G on the iPad costing no more than $30 a month, the iPad suddenly seems like a very attractive alternative to the iPhone with its far more expensive (and contractually obligated) carrier plans.
iCall [iTunes Link] has already been updated with VoIP over 3G enabled, and with all restrictions now lifted, it seems like it’s only a matter of time before Skype and other VoIP apps follow.
The Dumbing of America › History Lesson: Dave Wakeling and The English Beat
Some eighties bands music stands the test of time, while others cause us to look over our shoulder to see if anyone’s noticed the Heaven 17 album in our collection. The English Beat wrote songs with a reggae groove, but with enough pop sensibility to capture the hearts of millions. At a time when it was virtually impossible for alternative bands to get radio airplay in America, The Beat had a string of hits and sold-out tours. Dave Wakeling was the singer, guitarist and mastermind behind the whole thing and when he announced a 2010 U.S. tour for The Beat, we sought him out for an interview. On the phone, Wakeling engaged us for hours with discussions of politics, the music industry, VH1 and the process of making videos. Here are the best bits from our discussion.

Verizon Terminating Copyright Infringers’ Internet Access
Verizon is terminating internet service to an unknown number of repeat copyright scofflaws, a year after suggesting it was not adopting a so-called graduated-response policy.
While it was not immediately clear whether other internet service providers were following suit, the move comes as the Recording Industry Association of America and the Motion Picture Association of America are lobbying ISPs and Congress to support terminating internet access for repeat, online copyright offenders.
All the while, the United States has been privately lobbying the European Union to “encourage” so-called three strikes policies, according to leaked documents surrounding a proposed international intellectual property accord.
Verizon was not immediately prepared to comment in detail on the developments, first reported by CNET, or to detail how many of its more than 8 million broadband subscribers it has terminated — although CNET said the number was “small.” The RIAA declined comment.
“We reserve the right to do that,” Verizon spokeswoman Bobbi Henson said in a telephone interview regarding the terminations.
The RIAA announced a year ago it was ending its litigation campaign against individual file sharers, about 30,000 lawsuits in all. Instead, the music industry’s lobbying and litigation arm said it would rely on a series of accords it had reached with “leading” internet service providers, in which ISPs have agreed “on principle” to shut off internet access to customers the RIAA catches file sharing repeatedly.
At that time, in a Jan. 5, 2009 interview, Verizon spokeswoman Ellen Yu said that, in reference to the RIAA announcement: “We are not working with them on this.”
Cara Duckworth, an RIAA spokeswoman, said the same day that “We have an agreement on principle with several leading ISPs but not all, and the agreement on principle is confidential.”
Other than Verizon, none of the leading ISPs have acknowledged practicing what the content industry is calling “graduated response.” Under Verizon’s plan, the ISP notifies customers that unlawful file sharing allegedly is taking place on their accounts — file sharing discovered by the RIAA or other intellectual property holders who actively police networks and IP addresses. Internet service could be terminated perhaps after several warnings.

Savage police brutality revealed
A VIDEO released last week shows how a routine traffic stop by local police for a dragging muffler last November turned into a nightmare for Melvin Jones III.
Jones, an African American and resident of Springfield, Mass., was pulled over on November 27–and ended up in the hospital with severe injuries to his face, after he was beaten by Jeffrey Asher, a white police officer with a history of brutality against African Americans.
The video, which was posted online, was only just released after being quietly held “in the hands of law enforcement and city officials for several weeks,” according to Masslive.com/The Republican newspaper.

The Nexus One “has just had its price slashed,” Bunker reports.
“Up until today, anyone in the US who’d wanted to upgrade to the Nexus One on T-Mobile had to pay out $379,” Bunker reports. “With the price cut in effect, this figure stands at $279… Not only that, but anyone who’s already upgraded receive a $100 refund.”
