So chicken feather charcoal might solve the storage problem for the new hydrogen economy. One problem down, half a zillion to go."

The problem: when I am home I don't want to carry my phone on my person, AND I don't want to have to run (possibly up or down stairs) to answer a call. Landlines solved this with extensions. I could go buy an xlink or other Bluetooth-to-POTS solution, but that takes money for equipment. My desktop has Bluetooth, as do my laptop and cell. All I want is a program that can use my cell's Bluetooth to make and receive calls from my Linux PC. I can do this with asterisk or related programs, but that is like buying UPS when I just need a taxi ride. Yet all I can find are programs that either use 'presence' to shift other-sourced calls to my cell, or ways to use a Bluetooth headset when receiving a call on a PC. Has anyone found a way to use their desktop to make and receive calls through their cell via Bluetooth?"

Riffing off David's recent post about stoned wallabies making crop circles, here is yet another set of "crop circles," made this time not by marsupials but by the gravesites of prehistoric man. From National Geographic

A thousand years older than nearby Stonehenge, the site includes the remains of wooden temples and two massive, 6,000-year-old tombs that are among "Britain's first architecture," according to archaeologist Helen Wickstead, leader of the Damerham Archaeology Project.

Discovered during a routine aerial survey by English Heritage, the U.K. government's historic-preservation agency, the "crop circles" are the results of buried archaeological structures interfering with plant growth.

theodp writes "While the White House has invited the nation to Join the National Online Discussion on Health Care Reform, it is currently only accepting 20-30 second YouTube video responses — text comments have been disabled. Which raises a question: Should a video camera be the price of admission for participating in an open government discussion, especially when issues may hit those with lower incomes the hardest? BTW, the response-to-date has been underwhelming — 101 video responses and counting — and is certainly a mixed-bag, including a one-finger salute, a talking butt, a woman "Showing my Apples", and other off-topic rants and unrelated videos."

My Dad got a shiny new red tractor the week before Father's Day, which created a great opportunity for an easy, inexpensive, handmade gift: I bought a classic little red toolbox, to match the tractor, and fitted it with eight 3/4" ring supermagnets on the bottom to make it stick to the fender. There's a rubber washer between each magnet and the bottom of the toolbox, to cushion the magnets, each of which is secured using a 3/4" automotive panel fastener--basically a barbed plastic push fastener.

Inserted through the hole in the magnet, through the rubber washer, and through a 1/4" hole drilled in the bottom of the toolbox, the panel secures everything in place. The head of the fastener also makes a nice black plastic "foot" on the bottom of each magnet, which protects the finish on the tractor from marring against the magnet, without being so thick as to block magnetic attraction.

NewYorkCountryLawyer writes "One thing you don't see too much of in RIAA litigation is a defendant moving for summary judgment, but that is what just occurred in federal court in Westchester, in Lava Records v. Amurao II. The RIAA had brought suit against Rolando Amurao, a middle aged man who knew nothing about file sharing. After haranguing him for 2 years, they dropped the case and sued his daughter, Audrey, who had used LimeWire years ago. When the RIAA moved for summary judgment against Audrey, however, she surprised them with a summary judgment motion of her own, calling for dismissal of the complaint on the grounds that the statute of limitations had run out on the RIAA's claims. The brief filed by her attorney (PDF) also points out some of the other infirmities in the RIAA's case, such as the inadmissibility of its evidence, the legal nonexistence of a claim for 'making available', and the unconstitutionality of its damages theory. According to sources, the RIAA is unhappy about Audrey's motion, and is preparing a letter to send the Judge asking the Judge not to allow her to make it. Meanwhile, Audrey's father's case, Lava Records v. Rolando Amurao, is on appeal in the US Court of Appeals for the 2d Circuit over the issue of whether the RIAA should have to reimburse Mr. Amurao for his attorneys fees. Although the appeal was fully briefed and scheduled for argument May 19th, the RIAA has been asking for postponements of the argument."

jra writes "For over 5 years, various people both inside and retired from NASA have been engaged in a quest. They were looking for the long-lost original slow-scan video tapes from the Apollo 11 moon landing, which went missing in a record-keeping snafu, covered in unreasonable detail in a Wired article a couple years ago. Well now, according to the UK's Sunday Express newspaper, some tapes may or may not have been found which may or may not be the Apollo video. Apparently — I love the British press — the NASA boffins are a bit put out that it leaked; they were hoping to blow everyone's minds with the scoop themselves."

An article at TechCrunch discusses a blog post from Richard Posner, a US Court of Appeals judge, about the struggling newspaper industry. Posner explains why he thinks the newspapers will continue to struggle, and then comes to a rather unusual conclusion: "Expanding copyright law to bar online access to copyrighted materials without the copyright holder's consent, or to bar linking to or paraphrasing copyrighted materials without the copyright holder's consent, might be necessary to keep free riding on content financed by online newspapers from so impairing the incentive to create costly news-gathering operations that news services like Reuters and the Associated Press would become the only professional, nongovernmental sources of news and opinion."

Oracle Goddess writes "As part of a project to issue ID cards for all 1.1 billion of its citizens, India has announced plans to place information on every single citizen in what will be the world's second largest citizens' database. The government believes the scheme will aid the delivery of vital social services to the poorest people who often lack sufficient identification papers. It also sees the scheme as a way to tackle increasing amounts of identity fraud and theft, and, at a time of increased concern over the threat of militant violence, to boost national security and help police and law officials. 'This could be used as a security measure by the government which leaves migrant workers, refugees and other stateless people in India in limbo, without access to public services, employment and basic welfare,' said Charu Lata Hogg, an associate fellow of the Asia program at Chatham House."

Matt Asay writes "Walk the halls of any open-source conference and you'll see a large percentage of attendees with ironically non-open-source Apple laptops and iPhones. One reason for this seeming contradiction can be found in reading Matthew Thomas' classic 'Why free software usability tends to suck.' Open-source advocates like good design as much as anyone, but the open-source development process is often not the best way to achieve it. Open-source projects have tended to be great commoditizers, but not necessarily the best innovators. Hence, Red Hat CEO Jim Whitehurst recently stated that Red Hat is "focused on commoditizing important layers in the stack." This is fine, but for those that want open source to push the envelope on innovation, it may be unavoidable to introduce a bit more cathedral into the bazaar. Without an IBM, Red Hat, or Mozilla bringing cash and discipline to an open-source project, including paying people to do the 'dirt work' that no one would otherwise do, can open source hope to thrive?"

Amyloo pointed out that arriving in a new city would have been a blog post three years ago. She's right. I think it deserves a blog post this year as well.

Yesterday I completed my third visit to Copenhagen with a visit to an ancient castle in Helsignor, where Shakespeare set Hamlet.

From there we went to an incredible art museum on the shore of the sound that Copenhagen is on. I took a bunch of pictures.

Finally we went to dinner at a nice restaurant in Christiania, an outlaw community within Copenhagen

Today, after breakfast with Thomas Madsen-Mygdal, I left for Berlin, which I can already tell is a spectacularly beautiful city, even though I've only been here an hour. I'm staying at the Grand, a beautifully restored historic hotel where one of my favorite movies of the 1930s was set. Getting off the elevator, I laughed because I immediately recognized it as a set where Joan Crawford, Greta Garbo and John and Lionel Barrymore performed their magic. It's a gorgeous hotel. I can't imagine it looked any nicer in 1932.

I have a very pragmatic reason for wanting to post something on the blog. I am here in a strange city on my own. Reaching out to any readers of this blog, let's have a dinner. I'm here for three nights. I love beer. I hear there's some good beer here!

Michael Jackson's death caused radio's roboprogrammers to take a back seat for a while. Increasingly, over the past few decades, broadcast radio has ceased to be a local affair. As the FCC regulations on local ownership of media outlets has faded towards corporate behemoths, radio programming more and more these days is done by databases and distant decision makers. For those of us who remember real radio dj's who made personal decisions about what song would come next, this has driven us more towards our own music collection, rather than being stuck listening to the corporate drivel. Pandora and Last.fm are okay, but they lack the personal touch.

With Michael Jackson's death announcement, the clacker driven music machine was taken off line, if only for a few hours and only on a few stations. Human beings again ruled the airwaves of some radio stations.

"It's a good reminder of what live radio can do, of the role that radio can play in bringing a community together,'' said Scott Fybush, editor of Northeast Radio Watch in Rochester, N.Y.

Many stations no longer have live announcers, using canned voices for part or all of the day, and so can't react to a major news event, he said.

DJ Deirdre Dagata, 39, has been working at Mix 98.5 part time since May, after being replaced at Kiss 108 by recorded programming the month before. And yesterday, she was back in action for the biggest radio day in memory.

Dagata was in constant motion during her 9 a.m. to 2 p.m. shift. Sitting in an elevated office chair in front of four computer screens, she punched blinking phone lines, tapped on keys, and slid knobs - simultaneously editing recorded calls and fielding a steady stream of new ones from listeners who wanted to share stories about Jackson.

Back in the day, I recall listening to the radio knowing something unique was happening. The radio announcers had their own tastes in music, and they helped to create a following around their musical tastes. Sometimes there was dead air as the dj missed the cue for a variety of human reasons, some more innocent than others. This caused me to volunteer at and work at several radio stations in the 1980's and 1990's. I actually chose my university because I liked the on air feel of the campus radio station, which turned out to be a very influential organization for me. At the station, I did on-air work, production of public service announcements, newscasts, dj training, and eventually became Program Director. The audience's active listenership of the music and programming was exciting to be involved with.

Back then, radio was a public service to be provided to the community, not just a marketing opportunity. Almost radio programming was done with people at the microphones, nearly always they were playing actual records, tapes or cds. Even the commercials were created in-house, except those for national campaigns.

Do you miss real radio? There are a bunch of college radio stations around, and most of them depend on the student body and sometimes local community members to create their programming. With web streaming, it is possible to listen way beyond the broadcast range of your favorite station. WERS in Boston plays a good mix curated by communications students. KEXP in Seattle has a wonderful mix of live performances and genuine djs choosing the music they play. Transom and Youth Radio are helping to cultivate the new voices of radio that we need. Public Radio Exchange has a channel on XM radio, and features a mix of voices that you may not have heard before.

With podcasting and the great suite of computer software and hardware available for free, just about everybody has the radio recording studio in their laptop, desktop, cellphone and digital camera that I had in my bedroom as a high school kid. If you want to broadcast, you may want to build your own transmitter. Sending out your homebrew radio programming out to your house or close neighbors could be a neat experience. You could record some short pieces like songs, jokes, or seque buffers, drop them into your music library and set your music player loose, sending your personalized radio program out to the transmitter.

Radio used to be a LOT of fun as a listener and programmer. Now the tools are much easier to get and use for us regular folks. Hopefully, the corporations will lighten up on their centralized programming and return to the human touch of radio, but even if they don't we can realize that we can choose what radio we listen to or create. If you have any stories of making your own or listening to real radio, pirate or otherwise, tell us in the comments.

paimin writes "A struggle is breaking out in San Francisco over whether the developer of a publicly-funded installation of real-time tracking for the San Francisco Municipal Transit Agency has a right to control the use of data from the system. The situation is not totally clear, but this sure seems like an attempt to use patent threats to hijack public data. The city paid for the system, and the developer claims he lost money on the deal, so now he's shutting down applications like Routesy and Munitime that use data from the system unless they license the 'copyrighted' data from him."

Barometer World is a store in Okephampton, England that specializes in the sale and repair of instruments that determine atmospheric pressure. After two years of research, its proprietor built a reproduction of one of the most whimsical weather-forecasting devices of all time, the "Tempest Prognosticator," a.k.a. the "Leech Barometer," a.k.a. the "Atmospheric Electromagnetic Telegraph." The instrument, which uses fresh water leeches to predict incoming storms, was first exhibited at the Great Exhibition in London in 1851:

A contemporary account of the invention described it as an "elaborate and highly ornate apparatus... evolved by a certain Dr. Merryweather (no epigram intended) who had observed that during the period before the onset of a severe storm, fresh water leaches tended to become particularly agitated. The learned Doctor decided to harness the physical energy of these surprisingly hysterical aquatic bloodsuckers to operate an early warning system. On the circular base of his apparatus he installed glass jars, in each of which a leech was imprisoned and attached to a fine chain that led up to a miniature belfry--from whence the tinkling tocsin would be sounded on the approach of a tempest."

The more bells that rang, the greater the likelihood of an impending storm.

UPDATE: The above photograph is of the other Tempest Prognosticator reproduction, built in 1951 for the Whitby Museum in North Yorkshire.

DesScorp writes "Investigators working with the wreckage of Air France flight 447 believe the aircraft suffered cascading system failures with the on-board computers, eliminating the automation the aircraft needed to stay aloft. 'Relying on backup instruments, the Air France pilots apparently struggled to restart flight-management computers even as their plane may have begun breaking up from excessive speed,' reports the Wall Street Journal. Computer malfunctions may not be an isolated incident on the Airbus A330, as the NTSB is now investigating two other flights 'in which airspeed and altitude indications in the cockpits of Airbus A330 aircraft may have malfunctioned.'"

christian.einfeldt writes "The Munich decision to move its 14,000 desktops to Free Open Source Software created a big splash back in 2003 as news circulated of the third-largest German city's defection from Microsoft. When it was announced in 2003, the story garnered coverage even in the US, such as an extensive article in USA Today on-line. Currently, about 60% of desktops are using OpenOffice, with the remaining 40% to be completed by the end of 2009. Firefox and Thunderbird are being used in all of the city's desktop machines. Ten percent of desktops are running the LiMux Debian-based distro, and 80% will be running LiMux by 2012 at the latest. Autonomy was generally considered more important than cost savings, although the LiMux initiative is increasing competition in the IT industry in Munich already. The program has succeeded because the city administration has been careful to reach out to all stakeholders, from managers down to simple end users."

Comics writer Mark Sable was detained and intensively questioned by the TSA for carrying a script for an upcoming comic book about a writer who is detained and intensively questioned by the TSA for writing a comic about terrorism.

"Flying from Los Angeles to New York for a signing at Jim Hanley's Universe Wednesday (May 13th), I was flagged at the gate for 'extra screening'. I was subjected to not one, but two invasive searches of my person and belongings. TSA agents then 'discovered' the script for Unthinkable #3. They sat and read the script while I stood there, without any personal items, identification or ticket, which had all been confiscated.

"The minute I saw the faces of the agents, I knew I was in trouble. The first page of the Unthinkable script mentioned 9/11, terror plots, and the fact that the (fictional) world had become a police state. The TSA agents then proceeded to interrogate me, having a hard time understanding that a comic book could be about anything other than superheroes, let alone that anyone actually wrote scripts for comics.

"I cooperated politely and tried to explain to them the irony of the situation. While Unthinkable blurs the line between fiction and reality, the story is based on a real-life government think tank where a writer was tasked to design worst-case terror scenarios. The fictional story of Unthinkable unfolds when the writer's scenarios come true, and he becomes a suspect in the terrorist attacks.

"In the end, I feel my privacy is a small price to pay for educating the government about the medium."

Well, classes are finally over, and people like Charles can finally settle down to the important work of...extreme grocery carting:

While I seem to be in "build season" mode year-round, it is during long breaks with little in the way of academic or life obligations that I get the most done. Last summer, I began work on LOLrioKart and built Überclocker, Pop Quiz 2, and Nuclear Kitten for Dragon*Con.

So, for many of us, summer has arrived. Whether you are a teacher, student or neither, you likely have some essential experiment, project, mission or other task for the curious long days ahead. Fill us in through the comments, and point out some links so that we can see your winter and spring dreams come to summer's reality.
