Carla and I went to the 2009 San Francisco Zine Fest on Sunday. I was surprised to discover that the world of print zines is as vibrant and fun as it was back when bOING bOING was being published in the 80s and 90s.
I took photos of quite a few zine publishers who were in attendance, which I'll share with you over the next several days.
First up is Sean Logic, shown above. When I asked to take his photo, Sean covered his face with a copy of his one-shot zine, The Great MySpace Swindle, which is a griefer-lite account of how he set up a MySpace account pretending to be "Amber, a busty beautiful brunette who loved nothing more than to party and throw gang signs at the camera." The zine compiled all the responses to "Amber." Kind of a mean trick, but at least he didn't reveal the true names and accounts of the men who sent messages!
If you're interested in ordering a copy of The Great MySpace Swindle, send an email to myspace_swindle@yahoo.com. I think it cost $2, but I can't remember for sure.

Most home metal-casters use traditional green-sand molding techniques to cast parts. Typically, a two-part molding flask is packed with specially-treated sand around a pattern, then the flask is carefully opened, the pattern removed, and the flask reassembled, being careful not to disturb the sand impressions, leaving a negative space in the exact shape of the original. In lost-foam casting, however, the pattern does not have to be removed before pouring in the molten metal; rather, the hot melt simply vaporizes the foam as it flows in, and replaces it. This process has a number of advantages to recommend it over the traditional technique. It does not require a two-part flask, and can be performed in a simple metal bucket. Nor does it require special sand, or special techniques for handling it. Dave Kush has a great overview on his site. Among other things, Dave uses the lost-foam process to cast homemade linear bearings for his CNC equipment.

The court would like to make CM/ECF filers aware of certain security concerns relating to a software application or "plug-in" called RECAP, which was designed to enable the sharing of court documents on the Internet.I especially like the "scare quotes" around "open-source." Of course, I'm not quite sure why the fact that the extension is open source makes it any more vulnerable to being "modified for benign or malicious purposes." Either way, looks like the Federal Courts don't like competition eating away at their PACER profits.
Once a user loads RECAP, documents that he or she subsequently accesses via PACER are automatically sent to a public Internet repository. Other RECAP/PACER users are then able to see whether documents are available from the Internet repository. At this time, RECAP does not appear to provide users with access to restricted or sealed documents.
Please be aware that RECAP is "open-source" software, which means it can be freely obtained by anyone with Internet access and could possibly be modified for benign or malicious purposes. This raises the possibility that the software could be used for facilitating unauthorized access to restricted or sealed documents. Accordingly, CM/ECF filers are reminded to be diligent about their computer security and document redaction practices to ensure that documents and sensitive information are not inadvertently shared or compromised.
The court and the Administrative Office of the U.S. Courts will continue to analyze the implications of RECAP or related-software and advise you of any ongoing or further concerns.

Bean remembers running next to this crater and feeling like he could run forever without his legs getting tired. The reason he felt "super strong" was because he weighed so little. The Moon has one-sixth the gravity of Earth, making his total body and equipment weight of about 136 kilograms (300 pounds) on Earth only 23 kilograms (50 pounds) on the Moon."Alan Bean: Painting Apollo, First Artist on Another World"
Although carrying weight required little effort, the spacesuits were stiff and hard to move at the knee and hip joints. Astronauts learned to move mostly by ankle motion, which Bean says "feels and looks as if you are dancing on tiptoe."

When Virtumundo's collections lawyer showed up at Gordon's house with a moving van and a sheriff, Virtumundo again offered to stop its pursuit of Gordon's assets if he would drop his appeal, and he refused again, according to Newman.As much as I thank anti-spam activists for trying to stomp out spam, that doesn't mean they get to ignore what the law allows, and set up what was effectively a professional anti-spam litigation service.
Virtumundo's collections agency then cleared out Gordon's house, according to Newman.
He added that after seizing the contents of Gordon's home, Virtumundo offered to return Gordon's belongings if he would drop his appeal and again, Gordon refused.
Relampago del Catatumbo(The phenomenon) was first written about in the 1597 poem "The Dragontea" by Lope de Vega. De Vega tells of Sir Francis Drake's 1595 attempt to take the city of Maracaibo by night, only to have his plans foiled when the lightning storm's flashes gave away his position to the city's defenders.
It's still unknown exactly why this area--and this area alone--should produce such regular lighting. One theory holds that ionized methane gas rising from the Catatumbo bogs is meeting with storm clouds coming down from the Andes, helping to create the perfect conditions for a lighting storm.

Latest "Gadget FreaK' is up - Build your own universal remote control
Couch potatoes should be particularly interested in Bill Bowden's remote control IR receiver, which allows users to control the power of virtually any electrical appliance (including those not equipped for remote) using their standard remote control. It's based on an IR receiver circuit, which is basically a simple toggle switch that features a 48KHz IR receiver module to convert IR signals to 5V digital data representing the particular command sent. So switch a fan or lights on and off, blend up a pitcher of margaritas, pop popcorn and more, all without leaving your couch — possibly ever.Read more | Permalink | Comments | Read more articles in DIY Projects | Digg this!

Circular walking occurs when people have to rely solely on bodily cues, such as rotational shifts and joint movements, to estimate the location of “straight ahead,” (researcher Jan) Souman hypothesizes. As random errors in bodily feedback accumulate, a person eventually drifts to one side or the other. A walker dependent on bodily cues may first make a circle to the right, drift back to a straight-ahead direction, start to zigzag and then make a circle to the left."How to walk in circles without really trying"
“You may think that you’re walking in a straight line, but in fact the direction you’re walking in is drifting more and more away from straight ahead, making you walk in circles,” Souman says...
Psychologist John Rieser of Vanderbilt University in Nashville calls the new findings exciting. He and his colleagues have found that blindfolded people veer off course but don’t circle when walking up to 100 meters across a grassy field. But cues from the ground, such as variations in grass length in an otherwise predictable environment, may have reduced veering from a straight line, Rieser says. “I suspect that one’s subjective sense of straight ahead, and up-down too, are easily changed by environmental conditions,” he remarks.

Images of gigantic jets have only been recorded on five occasions since 2001. The Duke University team caught a one-second view and magnetic field measurements that are now giving scientists a much clearer understanding of these rare events."Lightning's Mirror Image ... Only Much Bigger"
"This confirmation of visible electric discharges extending from the top of a storm to the edge of the ionosphere provides an important new window on processes in Earth's global electrical circuit," said Brad Smull, program director in NSF's Division of Atmospheric Sciences, which funded the research.
"Our measurements show that gigantic jets are capable of transferring a substantial electrical charge to the lower ionosphere," (Duke professor Steven) Cummer said.
"They are essentially upward lightning from thunderclouds that deliver charge just like conventional cloud-to-ground lightning. What struck us was the size of this event."

More in my series of posts on How to Build a Catapult. In this post, I discuss Catapults, Ballistas, Trebuchets and the Triggers, Releases, and Latches that operate them.
I receive quite a few inquiries about making catapults and trebuchets. And among the most frequent questions is: how do I build the trigger? It's an important question.
Catapults are fun and educational to build and operate. When building a catapult, trebuchet, ballista, mangonel, or any of the hundred names by which such hurling machines are known, you'll find out that the mechanism that releases the throwing arm is often the most complicated part of the machine.
You may build your own release, which is tricky because you need to design the latch so that it will release reliably under full load. Actually, you can get pretty creative about triggers.
But considering how cheap and easy it is to buy one, it might make more sense to use one of the commercial solutions below, and spend your time working on the other aspects of the machine.I've spent time researching the best triggers and releases for small catapults. There are three good, off-the-shelf solutions: The archer's arrow release, the sailor's pelican hook, and the horse trainer's panic snap.
Archer's Arrow Release:
This is the premier solution. Works dependably, quickly and very smoothly. It costs a bit more, but of all the catapult releases I've tried, I like this one the best. Find it at a sporting goods store with an archery department, or find it online.
Sailor's Pelican Hook:
This is another excellent hurling machine trigger. Its normal use is in sailing, where it is used to securely hold and release lines and ropes. Basically a pelican hook is a hinged hook that can be quickly secured or released by a sliding ring. It is quite a bit less expensive than an arrow release, but it holds securely under load. The downside is that they can be awkward to release sometimes. Find it at a boating store or online.
Horse Trainer's Panic Snap:
A panic snap is a mechanism often used between a lead and a horse's harness. They are decent catapult triggers because they can be disconnected under load. A panic snap is specially built so that the latching mechanism is separate from the load bearing structure. Just pull back on the latch and the load releases. Very inexpensive, but not as smooth or dependable as the arrow release. Find it at a tack shop or online.

Now this isn't illegal. Nor should it be. But it is rather unprofessional. And I think it's a good illustration of what's wrong with the standard story about large media organizations producing the news and blogs cutting and pasting. Not only does the sharing goes in both directions, but I think people have a skewed perception of which direction is more common precisely because blogs do a better job of crediting their sources. When Gawker builds on a Washington Post story, they don't try to pretend it was original reporting; they give credit, provide a link, and they'll often just quote the original story rather than re-interviewing all the same sources. So it's obvious who's copying whom. In contrast, when a mainstream media outlet like CNN decides to build on the reporting of an online source, they do a lot of extra (and possibly unnecessary) work to avoid giving credit. One consequence is that only in really blatant cases (like this one) does anyone catch them.Indeed. But whereas the story from the Washington Post reporter kicked up a huge discussion on ethics of reporting, who wants to bet that this one dies a quiet death without the mainstream media mentioning it at all?
There's a clear double standard here. If it's wrong for a blogger to build a story on a mainstream media story with attribution and a link, it's even more wrong for a mainstream media outlet to build on a blogger's story without a word of credit. CNN owes Radley a prominent link to his past work. And an apology.
Although it isn't finished yet, this homebrew cutoff saw project by Lionel Oliver, Jr. of backyard metalcasting puts my jaw on the floor. Maybe if we send a little link-love his way he'll get inspired to finish it up.

1. If the coin is tossed and caught, it has about a 51% chance of landing on the same face it was launched. (If it starts out as heads, there's a 51% chance it will end as heads).The Coin Flip: A Fundamentally Unfair Proposition? (via Schneier)2. If the coin is spun, rather than tossed, it can have a much-larger-than-50% chance of ending with the heavier side down. Spun coins can exhibit "huge bias" (some spun coins will fall tails-up 80% of the time).
3. If the coin is tossed and allowed to clatter to the floor, this probably adds randomness.
4. If the coin is tossed and allowed to clatter to the floor where it spins, as will sometimes happen, the above spinning bias probably comes into play...

DIY ECG Machine On The Cheap (via Make)Digitization: Once amplified, the ECG signal along with a bunch of noise is in analog form. You could display the output with an oscilloscope, but to load it into your PC you need an analog-to-digital converter. Don't worry! If you've got a sound card with a microphone input, you've already got one! It's just that easy. We'll simply wire the output of our ECG circuit to the input of our sound card, record the output of the op-amp using standard sound recording software, remove the noise from the ECG digitally, and output gorgeous ECG traces ready for visualization and analysis!
I imagine attention festivals: week-long multimedia, cross-industry carnivals of readings, installations, and performances, where you go from a tent with 30-second films, guitar solos, 10-minute video games, and haiku to the tent with only Andy Warhol movies, to a myriad of venues with other media forms and activities requiring other attention lengths. In the Nano Tent, you can hear ringtones and read tweets. A festival organized not by the forms of the commodities themselves but of the experience of interacting with them. Not organized by time elapsed, but by cognitive investment: a pop song, which goes by quickly, can resonate for days; a poem, which can go by more quickly, sticks through a season. A festival in which you can see images of your brain on knitting and on Twitter.A Short Manifesto on the Future of Attention (via Futurismic)I imagine a retail sector for cultural products that's organized around the attention span: not around "books" or "music" but around short stories and pop songs in one aisle, poems and arias in the other. In the long store: 5,000 piece jigsaw puzzles, big novels, beer brewing equipment, DVDs of The Wire. Clerks could suggest and build attentional menus. We would develop attentional connoisseurship: the right pairings of the short and long. We would understand, and promote, attentional health.

In Memoriam: My Manual Typewriter (via Beyond the Beyond)Examining my Olympia again, I'm struck by how powerfully its form and image embody and express the idea of writing, as does almost any typewriter. Like the telephone at an earlier phase in its development when it still had a distinct earpiece and mouthpiece at either end of a handle, the fully evolved typewriter is a 20th-century industrial archetype. It feels inevitable, almost elemental, like one of those object types, such as a chair or a fork, that simply had to exist in this universe of forms. Even now (but for how much longer?) a typewriter is the icon to show if you want to convey the idea of a dedicated literary life. The title page of The Rough Guide to Cult Fiction -- just out -- shows a portable typewriter on a desk with other writing paraphernalia. Turn the page and the caption reads "The essential equipment of a cult author, as collected by William Burroughs." Burroughs receives the longest entry in the book. The ultimate cult author -- the ultimate writing machine.

Mad Science 101: Inducing giantism in living organisms
For the control sample (marked Kontrol) we soaked one tablespoon of washed and sorted beans in water for twelve to eighteen hours. We then rinsed the beans and poured off the excess water twice a day. For the experimental sample (marked Kaos) we did the initial soak in our 100 ppm Gibberellic acid solution. Twice a day we rinsed, first in water which was drained off, then in the Gibberellic acid solution, pouring off the excess. Both jars were capped with cheesecloth and stored in a dark cabinet when not being rinsed or photographed...On day five, the experimental sprouts are definitely trying to escape. Sprouts are normally eaten on the fourth or fifth day, but we don't recommend eating the sprouts treated with Gibberellic acid (see MSDS).

Maker Scott Harden built a ultra-low-cost ECG machine using the sound card on his PC, some free digital audio processing software, a simple circuit, and a few pennies.
Although several DIY ECG guides exist on the internet, this one focuses on minimizing the part count and cost by performing noise reduction (normally handled by complicated analog circuitry) digitally with your computer. The device hooks up to your chest (using pennies as electrodes) and outputs to the microphone jack of your computer sound card so it can be recorded with free audio software. In addition to a description of how to build and use the DIY ECG, this guide also provides the code needed to perform complicated long-term heart rate and heart rate variability analysis to assess neurological control over cardiac function!Read more | Permalink | Comments | Read more articles in Electronics | Digg this!

Silicon Alley Insider has an interesting piece about Yahoo's obsession with all-things-Twitter. And at the end they have an even more interesting strategy. "Yahoo should work to be a better place to use Twitter than Twitter.com."

My friend Cara just introduced me to the work of Japanese photographer and aquarist Takashi Amano. From his Wikipedia entry:
Takashi Amano is one of the most influential people in the freshwater aquascaping community. He can largely be credited with introducing Japanese gardening concepts such as Wabi-sabi and Zen rock arrangement to the aquascaping hobby. His tank compositions involve intricate, and typically asymmetrical (though balanced) arrangements of aquatic plants often augmented by river rocks and driftwood. His aquascapes are notable in that they often mimic nature in their appearance, and can be regarded as a form of art.
Besides his personal site, linked above, Mr. Amano also runs Aqua Design Amano, which specializes in high-end aquascaping equipment and supplies.

The Raëlians, a religious cult that basically gets you in the door with promises of free sex, then brainwashes you with a bunch of garbage about UFOs and cloning and giving all your money to the church, hosted a "topless rights" parade in Venice Beach today. Here's a short video snapshot I shot on my trusty iContraption. The parade was kind of a letdown, I was expecting more space aliens, or at least something with better art direction, like their Star Wars knockoffs. The premise of the march had something to do with the 14th amendment, and acceptance of the female body as a sacred vehicle for extraterrestrial meat-worship.
Moobs were displayed. Signs were carried. Some women paraded around with nipple-shaped pasties on. That's about it. Just another day in Venice.
