Sailing with Tyvek

Buying a manufactured sail can be very expensive. If you are making your own vehicle and want to experiment with wind-driven propulsion, you might want to check out the idea of using building wrap as a way of forming your sails:

Now plan the sail. For this first sail, let's not have battens; they would complicate things a lot. Draw a picture of it, and figure out if you can make the sail without a seam. Remember, as you draw it, there will be curve to the luff to shape the sail. And also, at each edge the sail will be two inches wider, for the taped hem. If you do need a seam, plan to use the edge of the material at the leach, and run the seam parallel to the leach, as in the sketch. Located in this way the force across the seam, tending to pull it apart, is kept at a minimum.

Let's make the leach and foot absolutely straight, unless the foot is to be attached to a spar. But any edge attached to a spar needs to be curved in order to get shape into the sail. The deepest part of the curve, for a reasonably stiff mast, ought to be one third of the way up the luff from the tack, and its depth should be one inch for each five feet of luff (or foot). By the way, for now let's call that point "D" for now. More about it later.

Now you need a gym or a dance floor, or something like that. You can guarantee the owner that you will not harm it. And you and your helper, if you have one, will for sure need a set of knee pads, like volleyball players and flooring people use, or you will come away with sore knees.

I like the suggestions on how to source the materials as inexpensively as possible, and the flexibility of the design. If you have tried this out, show us some photos or other documentation!

You can use the techniques for making a sail like this for your nascent parking lot surfer, kite, or other wind-powered transport. You will probably want to build and test a few before letting the shoreline leave your line of sight. Once you get the hang of the designing technique, then you may want to take the best of your plans to a professional sailmaker to have a formal, durable sail made up.

Covering a small city

I was walking on Solano Ave approaching Alameda when I saw a few people looking at an accident scene down the block.

Several fire trucks, a police car blocking traffic. I could see a bicycle and an ambulance. The other people didn't know what had happened beyond that there had been an accident.

I took a picture of course.

So now it's an hour later, I'm at the computer, and poking around the City of Berkeley website, the fire department, police, Alta Bates Hospital, and come up with nothing. There's no record of what happened, or is there?

if there is a log -- where is it?

If not, who do I talk with about getting one going?

It seems this is the most basic beginning to having an effective local website.

Does the Linux Desktop Innovate Too Much?

jammag writes "The Linux desktop has seen major innovation of late, with KDE 4 launching new features, GNOME announcing a new desktop, and Ubuntu embarking on a redesign campaign. But Linux pundit Bruce Byfield asks, do average users really want any of these things? He points to instances of user backlash, and concludes 'Free software is still driven by developers working on what interests or concerns them. The problem is, the days when users of free software were also its developers are long gone, but the habits of those days remain. The result is that developers function far too much in isolation from their user base.' Byfield suggests that the answer could be more user testing."

Google Suggest Disabled In China Due To Porn

I Don't Believe in Imaginary Property writes "The Chinese government has asked Google to disable Google Suggest because it has been suggesting that people search for pornography based on its analysis of the most popular search terms in China. This comes on the heels of a fake CCTV interview being used to support the government requirement that all new computers ship with the 'Green Damn' Internet censoring program, which is still in force, despite reports to the contrary." The story on the chinaSMACK site demonstrates that Chinese search engine Baidu features a comparable search-suggestion function, which similarly recommends adult-themed sites, but that the government has not attacked Baidu over the issue of porn.

Kindle, Zune DRM Restrictions Coming Into Focus

It's not news that the media you buy for both Kindle and Zune are protected by DRM. Readers are sending in stories of some of the ramifications of that fact. First, Absentminded-Artist notes an account at Gear Diary recounting what an Amazon rep told one user about download limits on Kindle books. "One facet of the Kindle's DRM has reared an ugly head: download limitations. Upgraded your iPhone recently? Bought a new Kindle? You may not be able to reload your entire library. There's an unadvertised flag: 'You mean when you go to buy the book it doesn't say "this book can be downloaded this number of times" even though that limitation is there?' To which [the rep] replied, 'No, I'm very sorry it doesn't.'" Next, reader Rjak writes "DRM is a bad idea, poorly implemented. One of the many many valid reasons to drop Zune and it's marketplace is the DRM validation error you see below. The vast majority of the music I had purchased last year is completely gone. There's no refund, the music doesn't exist on the service anymore, the files are just garbage now. Here's the error (screen capture): 'This item is no longer available at Zune Marketplace. Because of this, you can no longer play it or sync it with your Zune. There might be another iteration of it available in Zune Marketplace.'"

Vintage Tech archives in Bay Area seeks moving volunteers Sun 6/21, Mon 6/22.

moz-screenshot-122.jpg

Phil Lapsley, vintage computing history buff, writes:

VintageTech, the organizers of the Vintage Computer Festival, are moving their warehouse of historical computers, equipment, software, and documentation from Livremore, CA to Stockton, CA. Volunteers are needed today (Sunday) and tomorrow (Monday) in Livermore to help pack and palletize all their wonderful machines and related ephemera. It is an amazing chance to help a good cause and get up close and personal with a bunch of interesting historical stuff. I have posted a set of photos of some of their wonders at this Flickr link.

Bubble wrapping death masks

Joshua Foer is a guest blogger on Boing Boing. Joshua is a freelance science journalist and the co-founder of the Atlas Obscura: A Compendium of the World's Wonders, Curiosities, and Esoterica, with Dylan Thuras.

My wife and I are in the process of relocating from Brooklyn to New Haven. So far, the most tedious part of the move has been packing up the collection of death masks we acquired once upon a time in a fortuitous eBay bonanza:

deathmaskswall2.jpg

The majority of these heads are gazillionth-order plaster cast reproductions (knock-offs of knock-offs of knock-offs) of originals held in the Laurence Hutton Collection at Princeton. Several are actually life masks, originally cast by sculptors.

In roughly bottom-to-top, left-to-right order, the faces in this photo belong to:

On the ledge: Abraham Lincoln, Laurence Barrett, Sir Richard Owen, Robert E. Lee, John C. Calhoun, William Tecumseh Sherman

The bottom six hanging on the wall: Ludwig van Beethoven, Antonio Canova, John Keats, Hyrum Smith, Joseph Smith, Jean-Paul Marat

The next highest six: Franz Liszt, Napoleon Bonaparte (well, maybe), Frederick the Great, George Washington, William Blake, Oliver Cromwell

The next highest five: Jeremy Bentham, Aaron Burr, Friedrich Nietzsche, Edward Kean, Ulysses S. Grant

And the top row: Jonathan Swift, Maria Malibran, David Garrick, Thomas Paine, and Thomas Moore.

On another wall not pictured we've got: Robespierre, another Abe Lincoln, Frederic Chopin, Pope Pius IX, Benjamin Disraeli, Benjamin Franklin, and John Dilinger. Plus there are a few more whose names I've forgotten in storage.

If there's one death mask I wish we had, it would be the Inconnue de la Seine.



Jantar Mantar

Joshua Foer is a guest blogger on Boing Boing. Joshua is a freelance science journalist and the co-founder of the Atlas Obscura: A Compendium of the World's Wonders, Curiosities, and Esoterica, with Dylan Thuras.

JantarMantar.jpg

Following up on Dylan's post about the Electrum, the world's largest Tesla Coil, I'd like to mention my own favorite super-sized scientific instrument: the Jantar Mantar astronomical complex in Jaipur, India. Constructed almost three centuries ago, its 73-foot-tall sundial is the largest in the world:

In 1728, Sawai Jai Singh II, rajah of Jaipur, dispatched his emissaries across the globe to gather the most accurate astronomical data possible. When they returned, Jai Singh ordered the construction of the Jantar Mantar complex, a monumental astronomical observatory constructed entirely out of stone and based on the astronomical tables of the French mathematician Phillipe de la Hire. Among the stone instruments Jai Singh constructed was the Samrat Yantra, a 73-foot tall sundial which remains the largest ever built. Though indistinguishable in design from other dials of the day, it was far and away the most accurate. Its two-second interval markings are more precise than even la Hire's table.

UPDATE: Uh oh. The picture above is of the Jantar Mantar complex in Delhi. Here's a photo of the one in Jaipur:

jantarmantar2.jpg

UPDATE TO THE UPDATE: Oy. That second picture, which I nabbed off Wikipedia, may still not be the right Jantar Mantar. This one, I am confident, is definitely the Jantar Mantar in Jaipur. Sorry for the confusion.

The Whistling Island of La Gomera

silbador2.jpg

To follow up on Dylan's post about Ball's Pyramid, we've got a whole category of "Anomalous Islands" in the Atlas Obscura that is waiting to be filled out. One of my favorites is La Gomera, a small island in the Canaries, where people communicate with each other from miles apart using one of the most unusual languages in the world:

Known as Silbo, the whistling language of Gomera Island has a vocabulary of over 4,000 words, and is used by "Silbadors" to send messages across the island's high peaks and deep valleys.

Though Silbo was on the verge of extinction in the 1990s, the Gomerans have made a concerted effort to revive their language by adding it to the public school curriculum. Today 3,000 schoolchildren are in the process of learning it.

Here's a sampling of the language:



The Chappe Optical Telegraph

Joshua Foer is a guest blogger on Boing Boing. Joshua is a freelance science journalist and the co-founder of the Atlas Obscura: A Compendium of the World's Wonders, Curiosities, and Esoterica, with Dylan Thuras.

Chappe_semaphore.jpg

Before the telegraph, there was the optical telegraph, a chain of towers topped by large pivoting cross members, and spaced as far apart as the eye could see. Developed by the Frenchman Claude Chappe at the end of the 18th century, optical telegraph lines once stretched from Paris out to Dunkirk and Strasbourg, and were in service for more than half a century:

Chappe created a language of 9,999 words, each represented by a different position of the swinging arms. When operated by well-trained optical telegraphers, the system was extraordinarily quick. Messages could be transmitted up to 150 miles in two minutes.

Several optical telegraph relay stations are still around, including one in Saverne, France that was renovated in 1998.



The incredible “ear stones” of fish

Joshua Foer is a guest blogger on Boing Boing. Joshua is a freelance science journalist and the co-founder of the Atlas Obscura: A Compendium of the World's Wonders, Curiosities, and Esoterica, with Dylan Thuras.

otolith.jpg

Graham Burnett wrote a fascinating essay in Cabinet recently about otolithic organs, the pair of sensors in the inner ear that help us stay balanced and maintain inertia. "Grossly speaking," writes Burnett, the otolithic organs consist of "a bunch of tiny pebbles (of the white rock known as calcium carbonate) embedded in a gooey wad that sits atop a carpet of delicate hairs." In humans, those "pebbles" are practically microscopic, but in fish, they can be as large as marbles:

There are several thousand researchers around the world who spend their whole working day looking at fish otoliths. This has nothing to do with their physiological functions, however, and everything to do with their structure and the staggering amount of information they contain. In the first place, each species of fish has a unique otolith shape. Couple this with the fact that they are stone (and therefore comparatively resistant to decomposition), and their utility as a biological marker becomes clear. Interested in the food habits of bottlenose whales? Pump their stomachs and you will end up with relatively few bones but lots of otoliths. Find an otolith expert and he or she will be able to give you a menu...

But the true wonder of these peculiar pearls lies within. Should you have occasion to tonsure a snapper or sea-bass, slicing off the top of its skull just above the eyes, you might take a moment to remove the two largest otoliths (there are, as a rule, six in all, three on each side) from their velvet seats to the right and left of the brain stem. With the heel of a knife you should be able to snap one of them in two, and then, holding it to the light, you will discern a set of concentric bands. These are growth rings--annuli--which, properly counted, will give the age of your fish in years.



Iran Election Crisis: 10 Significant Web Videos


Over at Mashable, Ben Parr has compiled a post with 10 of the most-viewed, and most significant, "citizen videos" to have emerged from the ongoing turmoil in Iran. A snip from his postscript, appended to the post today:

As I built this post, I saw a progression of events through the video. Unfortunately, it wasn't a good one. It puts on display escalating violence, mayhem, and turmoil. Iran is a nation in chaos, and as we monitor the situation, we must realize that social tools provide us with unfettered access to the situation. Sometimes, that access can be disturbing. The flip side though is that we can truly know what's going on in Iran.

Roger Cohen in Tehran: “I don’t know where this uprising is leading.”

Snip from a New York Times op-ed by Roger Cohen, who is in Tehran.
The Iranian police commander, in green uniform, walked up Komak Hospital Alley with arms raised and his small unit at his side. "I swear to God," he shouted at the protesters facing him, "I have children, I have a wife, I don't want to beat people. Please go home."

A man at my side threw a rock at him. The commander, unflinching, continued to plead. There were chants of "Join us! Join us!" The unit retreated toward Revolution Street, where vast crowds eddied back and forth confronted by baton-wielding Basij militia and black-clad riot police officers on motorbikes.

Dark smoke billowed over this vast city in the late afternoon. Motorbikes were set on fire, sending bursts of bright flame skyward. Ayatollah Ali Khamenei, the supreme leader, had used his Friday sermon to declare high noon in Tehran, warning of "bloodshed and chaos" if protests over a disputed election persisted.

He got both on Saturday -- and saw the hitherto sacrosanct authority of his office challenged as never before since the 1979 revolution birthed the Islamic Republic and conceived for it a leadership post standing at the very flank of the Prophet.

Sothink Violated the FlashGot GPL and Stole Code

ShineTheLight sends in news of two Firefox plug-ins: FlashGot, the original, and Sothink, the GPL-violating come-lately. "People at Sothink decided to violate the GPL by stealing a piece of core code from FlashGot and using it without even the decency of covering their tracks. It is an exact copy of a previous version of FlashGot. This deception came to light when users reported to the FlashGot support forum that their software was not working right. Some digging led to the discovery that the older module that Sothink stole and used verbatim was overriding the more recent engine on the machines of those who had both installed and it was causing the issue. It has been reported to AMO and the FlashGot developer is aware of it. The Sothink people have completely ignored and been silent on the subject. This is why most good programmers will stop contributing to the global community because there are those who will steal their work, pass it off as their own, never acknowledge or give credit, and then shamefully stick their head in the sand and ignore the consequences." The three most recent reviews of Sothink point out this plug-in's dishonest nature. A number of earlier, one-line, 5-star reviews — expressed in a similar style — sound suspiciously like astroturfing.

Social Media in Iran: Lessons Learned (Ethan Zuckerman)

Here's a snip from a blog post by Ethan Zuckerman about lessons learned from many hours on the phone with reporters doing "social media in Iran" stories:
ethanz.jpg It's been an interesting few days for people who study social media. As the protests over election results have continued in Iran, and Iranian authorities have prevented most mainstream journalists from reporting on events, there's been a great deal of focus on social media tools, which have become very important for sharing events on the ground in Iran with audiences around the world. I, like many of my friends at the Berkman Center and Global Voices, have spent much of the past two days on the phone with reporters, fielding questions about:

- Whether social media is enabling, causing or otherwise driving the protests in Iran
- How Iranian users are managing to access the internet despite widespread filtering
- The ethics (and practice) of distributed denial of service attacks as a form of information warfare
- Whether such online activities are unprecedented

Rather than tell you what I and colleagues have been saying to reporters, I'll point you to one of the better stories, by Anne-Marie Corley in MIT's Technology Review - she interviews several of my Berkman and Open Net Initiative colleagues and outlines the argument many of us are making:

- Social media is probably more important as a tool to share the protests with the rest of the world than it is as an organizing tool on the ground.
- Iranians have been accessing social networking sites and blogging platforms despite years of filtering - there's a cadre of folks who understand how to get around these blocks and are probably teaching others.
- Because so many Iranians use social media tools - often to talk about topics other than politics - they're a "latent community" that can come to life and have political influence when events on the ground dictate.

Super-filtered #IranElection info for the easily overwhelmed

Jasmina Tesanovic: Less Than Human


(Ed. Note: The following guest essay was written by Jasmina Tešanovi?. Full text of essay continues after the jump, along with links to previous works by her shared on Boing Boing.)

Less than Human

(Video Link) Last week the Bosnian TV screened a set of private videos of the most wanted war criminal in the world, the Bosnian Serb Ratko Mladic. The video scandalized the world, and even us, those few in Serbia who don't live in denial.

We are those who believe their eyes more than their officials, who believe in facts more than in ideology, who believe that peace can come only through justice. And when I say us few, I refer to the activists, human rights lawyers, the families of Mladic's victims, and those people who, unwillingly, in one way or another, crossed the hidden path of the hidden General.

I remember, some years ago, a young human rights activist whose daily job was to hunt for war criminals. He met Mladic regularly while Mladic shopped in a bakery. My young friend gave up his job. The impotence of the law and the nonsense of politics made his life senseless.

The war criminal was frequently quoted as a hero of the Serbian people. Political rallies featured T-shirts with Mladic' s face. He was a a mythical figure, the Serbian hero sworn to kill himself rather than surrender to the Hague tribunal.

Was he hiding in the mountains, was he hiding in his Bosnian woods and caves, was he hiding in the dungeons of the Serbian army in Belgrade? Was he hiding at all? A couple of years ago two soldiers on duty close to these secret military dungeons were found dead. The official explanation was dubious: they either killed each other in a fight or committed suicide. What came out soon after was that they were allegedly witnesses of Mladic's hideout. This case is still a very suspicious mystery, since the parents and human rights activists are pursuing it relentlessly. Some time ago, the indicted private persons who supposedly helped Mladic in his hiding in Belgrade were let off the hook in a Serbian court, officially because of lack of evidence. I saw them leave the courtroom, boisterous and loud, while the witnesses were intimated and threatened. And now these home videos appear: Mladic is elderly, yet obviously not in hiding. He is our contemporary, living a normal life in recognizable neighborhood of Belgrade. He doesn't not seem hunted but protected.

Less than a year ago another war criminal Radovan Karadzic was arrested in Belgrade: disguised as a mystic alternative medicine guru Dragan Dabic. After his arrest many photos and clues circled in Belgrade: that Mladic might be disguised as a street seller, as a simple retired person in the park, even as a woman. But these videos disperse these rumors: the very last video shows Mladic with a cane, playing joyfully with snowballs. This shot confirms the rumors that he had a recent stroke, and that the footage is as recent as winter 2008.

Looking at this home movies, as boring and innocent as all family private movies are, something felt deeply wrong about them. We are looking at the world's most wanted war criminal, who executed in cold blood, in three days, 8000 people just because they were ethnic Muslims in the wrong place: cattle, less than human, as his soldiers called them.

In the gaze of the camera, he behaves as if nothing has happened. He is a simple family man. Mladic cuddles his newborn grandson with words of endearment. He hugs his always present loving wife and his devoted son. He weeps over the coffin of his daughter, who shot herself dead with his favorite gun. The horror of the vast crime he committed becomes even more gigantic. This man with emotions and ideas had no doubts about liquidating populations, without explanation, without hesitation. Mladic was considered a hero for that. From the home videos, you see this faith about his heroic deeds. He is surrounded by family friends, and even some politicians of his regime.

These people speak my language, they have the body language of my relatives from Herzegovina, but they don't speak my mind. Sincerely, they seem crazy to me. But in the real everyday politics, their presence is a shadow over Serbia. It makes everyday Serbian life seem insane.

These days, the European Community is strongly promising Serbia a new visa regime. One of the main conditions for Serbia's integration into te European Community was the arrest of Ratko Mladic. The public screening of these videos coincides with these new policy talks. It's hard to believe that timing is an accident.

Maybe we are closing in, maybe there is no other way to tell the Serbian people that Mladic is not a a superhuman hero of Serbian people, but a tottering old man, a character whose banality is classically evil.

Manga-bot makes coffee (sorta)

Francesco Fondi, of GAMERSWEB, sent us this video of Hina, a manga custom version of the Kondo KHR-2HV robot. It's a scaled-down version of KHR-2HV, using 20 digital servos (KRS-788HV) plus one GWS-PICO-STD, all controlled by a small board located in the head. While it "makes coffee" only through the miracle of video editing, the dexterity and range of motion and the feeling of it being alive is pretty impressive. And I love watching a robot working an old hand-grinder.

How RIAA Case Should Have Played Out

NewYorkCountryLawyer writes "If a regular 'country lawyer' like myself had taken a case like the RIAA's in Capitol Records v. Thomas-Rasset to court, he or she would have been laughed out of the courthouse. But when it's the RIAA suing, the plaintiffs are awarded a $1.92 million verdict for the infringement of $23.76 worth of song files. That's because RIAA litigation proceeds in a parallel universe, which on its face looks like litigation, but isn't. On my blog I fantasize as to how the trial would have ended had it taken place not in the 'parallel universe,' but in the real world of litigation. In that world, the case would have been dismissed. And if the Judge had submitted it to the jury instead of dismissing, and the jury had ruled in favor of the RIAA, the 'statutory damages' awarded would have been less than $18,000."

Questioning Mozilla’s Plans For HTML5 Video

AberBeta writes with this excerpt from OSNews: "We're on the verge of a serious evolution on the web. Right now, the common way to include video on the web is by use of Flash, a closed-source technology. The answer to this is the HTML5 video tag, which allows you to embed video into HTML pages without the use of Flash or any other non-HTML technology; combined with open video codecs, this could provide the perfect opportunity to further open up and standardize the web. Sadly, not even Mozilla itself really seems to understand what it is supposed to do with the video tag, and actually advocates the use of JavaScript to implement it. Kroc Camen, OSNews editor, is very involved in making/keeping the web open, and has written an open letter to Mozilla in which he urges them to not use JavaScript for HTML video."

Mayo Clinic Reports Dramatic Outcomes In Prostate Cancer Treatment

Zorglub writes "Two prostate cancer patients who had been told their condition was inoperable are now cancer-free as the result of an experimental therapy, the Mayo Clinic in Rochester announced Friday. 'Cancer has a propensity for turning off T cells. Dr. Allison hypothesized that if you block the off-switch, T cells will stay turned on and create a prolonged immune response. Dr. Kwon, then at NIH, demonstrated that CTLA-4 blockage could be used to treat aggressive forms of prostate cancer in mice. There was one limitation to that concept — the worry that by simply leaving all the T cells on there may not be enough response aimed at the tumor. Dr. Kwon called Dr. Allison and designed the trial together. The idea: use androgen ablation or hormone therapy to ignite an immune approach — a pilot light — and then, after a short interval of hormone therapy, introduce an anti-CTLA-4 antibody that acts like gasoline to this pilot light and overwhelms the cancer cells.' After the treatment, the patients' tumors shrunk to such a degree that they could be successfully removed."

The Newspaper Isn’t Dead Yet

theodp writes "Slate's Farhad Manjoo had high hopes for using the Kindle DX — Amazon's new large-screen e-reader — to read newspapers. A good first effort, says Manjoo, who concludes that for now newsprint still beats the $489 Kindle. While he has issues with latency, what he really misses relates to graphic design. The Kindle presents news as a list, leaving a reader to guess which pieces are most important to read. Newspapers, by contrast, opine on the importance of the day's news using easy-to-understand design conventions — important stories appear on front pages, with the most important ones going higher on the page and getting more space and bigger headlines. Also, because of its overnight delivery model, Manjoo gripes that the Kindle suffers from a lack of timeliness, making it not even as good as a smartphone."

Open source EV controller

OS_EV_controller.jpg

Photo from Paul and Sabrinas EV Stuff

Nikki likes this open source Electric Vehicle controller project. With an EV, your primary components are the motor, batteries, charger and the controller. If people can develop a design that will allow a more inexpensive and high quality motor controller, they can move the technology in a good way towards better components and systems. Nikki says:

They're looking for people to help with the project and donations to help finish the testing and documentation. It's certainly worth a go at building yourself, or working on with some students. They have some videos at YouTube of the conversion and the prototypes.

The OS EV motor controller project ReVolt wiki with a bit of info, including a set of photos showing the build process, and the MPGuino, to help keep track of your energy cost per mile.

If you are interested in the process of building an EV or even building your own electric motor controller, you will find this web site a great place to start. Our electric motor controller project involves not just us, but several gracious contributors from other sites including Ecomodder and the EV tech group.

You may want to listen in to the EVCast featuring the project.

Researchers Find Gaps In Iranian Filtering

I Don't Believe in Imaginary Property writes "With all the turmoil and internet censorship in Iran making it difficult to get an accurate picture of what's going, security researchers have found a way to locate gaps in Iran's filtering by analyzing traffic exiting Iran. The short version is that SSH, torrents and Flash are high priorities for blocking, while game protocols like WoW and Xbox traffic are being ignored, even though they also allow communication. Hopefully, this data will help people think of new ways to bypass filtering and speak freely, even though average Iranians have worse things to worry about than internet censorship, now that the reformists have been declared anti-Islamic by the Supreme Leader. Given the circumstances, that declaration has been called 'basically a death sentence' for those who continue protesting." Reader CaroKann sends in a related story at the Washington Post about an analysis of the vote totals in the Iranian election (similar to, but different from the one we discussed earlier) in which the authors say the election results have a one in two-hundred chance of being legitimate.

White House Panel Considers New Paths To Space

Neil H. writes "The White House's Human Space Flight Plans blue-ribbon panel (the 'Augustine panel') has posted the material from their first public meeting on the future of NASA's spaceflight program, which was held on Wednesday. NASA officials presented their Ares I rocket plans and their belief that they can work around its design flaws, with projected development costs ballooning to $35 billion. The panel also heard several alternative proposals, such as adapting already-existing EELV and SpaceX rockets to carry crew to orbit; these proposals would have better safety margins than the Ares I, be ready sooner, and cost NASA less than $2 billion to complete, but are politically unattractive."

EFF and PK Reluctantly Drop Lawsuit For ACTA Info

mikesd81 notes a press release on the EFF website that begins "The Obama Administration's decision to support Bush-era concealment policies has forced the Electronic Frontier Foundation (EFF) and Public Knowledge (PK) to drop their lawsuit about the proposed Anti-Counterfeiting Trade Agreement (ACTA). Federal judges have very little discretion to overrule Executive Branch decisions to classify information on 'national security' grounds, and the Obama Administration has recently informed the court that it intends to defend the classification claims originally made by the Bush Administration. ... Very little is known about ACTA, currently under negotiation between the US and more than a dozen other countries, other than that it is not limited to anti-counterfeiting measures. Leaked documents indicate that it could establish far-reaching customs regulations governing searches over personal computers and iPods. Multi-national IP corporations have publicly requested mandatory filtering of Internet communications for potentially copyright-infringing material, as well as the adoption of 'Three Strikes' policies requiring the termination of Internet access after repeat allegations of copyright infringement, like the legislation recently invalidated in France. Last year, more than 100 public interest organizations around the world called on ACTA country negotiators to make the draft text available for public comment."

Memory Usage of Chrome, Firefox 3.5, et al.

An anonymous reader writes "This experiment graphs the memory usage of Chrome and Firefox 3.5 (along with Safari and Opera) over a series of 150 Web page loads using an automated script. Firefox 3.5 shows the lowest memory usage in all categories, including average memory usage, maximum memory usage, and final memory usage. Chrome uses over 1 GB of memory due to its process architecture. Safari 4 and Opera show memory usage degradation over time, while Chrome and Firefox 3.5 are more reliable in freeing memory to the OS." IE 8 was not included "because the author could not find a way to prevent it from opening a new window on each invocation of the command."

Best Handset For Freedom?

Father Thomas Dowd writes "The images we are seeing of Iran are being captured on cell phones and the text is being twittered over SMS. Still, the government has some control over the networks, and we are all familiar with fears of wiretap technologies to spy on users. If the cell phone is the new tool of freedom, what would the best 'freedom handset' contain? I'm thinking of a device with an open OS, where each phone could be a router for encrypted messages passed through Bluetooth/WiFi/whatever, thereby totally bypassing physical infrastructures when necessary. Of course, some sort of plausible deniability encryption a la Truecrypt would also be good, in case the secret police catch you with your phone. What else might we need?"

German Member of Parliament Joins Pirate Party

Political Observer writes "Jörg Tauss, a member of the German Parliament (Bundestag), left the Social Democratic Party SPD, which is part of the coalition government, and announced that he is joining the German Pirate Party (Google translation; original German article). Tauss resigned from the SPD after all but four of the party's members voted for a new censorship law, which passed the parliament on Thursday. The law, which aims at reducing child pornography, introduces an infrastructure for DNS-based content blocking and is the subject of major criticism from Internet users. In March 2009 Tauss became the subject of investigations by the German police for possession of child pornographic material. He said he had this material only for research as part of his role as a member of parliament. Investigations are still continuing."
