Eric_S writes "Anybody who managed to get a decent city going in Sim City 2000 remembers the microwave power plant; now it seems like a real-world equivalent might be coming up on the horizon. The Pacific Gas and Electricity Company, per this 'interview' with the CEO of Solaren on their affiliated site, announced PG&E's plans to buy 200MW of base-load power from a Solaren beamed space solar power plant by 2016." I wish the skeptic in me would be quiet.

Hugh Pickens writes "The Telegraph reports that scientists have found that if you want to get someone to do something, ask them in their right ear. Known as the 'right ear advantage,' scientists believe it is because information received through the right ear is processed by the left hand side of the brain which is more logical and better at deciphering verbal information than the right side of the brain. 'Talk into the right ear you send your words into a slightly more amenable part of the brain,' say researchers. The team, led by Dr. Luca Tommasi and Daniele Marzoli from the University of Chieti in central Italy, observed the behavior of hundreds of people in three nightclubs across the city where they intentionally addressed 176 people in either their right or their left ear when asking for a cigarette. They obtained significantly more cigarettes when they made their request in a person's right ear compared with their left. 'These results seem to be consistent with the hypothesized specialization of right and left hemispheres,' say researchers. 'We can also see this tendency when people use the phone, most will naturally hold it to their right ear.'"

eldavojohn writes "The Pentagon's been planning a cyber command for a while now but it's just been confirmed. The Pentagon will set up a Cyber Command outfit most likely around — surprise surprise — Fort George G. Meade in Maryland. From the article, 'The head of the Cyber Command would also be the director of the U.S. National Security Agency, which conducts electronic surveillance and communications interception and is also based at Fort Meade.' The Air Force has been no stranger to digital warfare."

Omomyid writes "The AFP is reporting the discovery of a 35,000 year-old flute, made from a vulture wing bone. The context described makes it sound like a musician's shop. There were also fragments of ivory-based flutes and flint tools. Being at least 35KYO this bone flute beats the previous oldest-known musical instrument by at least 5,000 years and puts it very close to the beginning of the Aurignacian culture."

DesScorp writes "Aviation Week reports on a television special from the National Geographic Channel on what may have been the world's first true stealth fighter, the Horten Ho 229, a wooden design that was to include a layer of carbon material sandwiched in the leading edge to defeat radar. Northrop Grumman, experts at stealth technology from their Tacit Blue and B-2 programs, have built a full-size replica of the airframe and tested it at their desert facilities where they determined that the design was indeed stealthy, and would have been practically invisible to Britain's Chain Home radar system of WWII."

dinoyum writes "Censorship in China is nothing new, but the level of action taken to force Chinese citizens to comply has garnered global recognition. China marked the date July 1st, 2009 as the day manufacturers will be forced to install filtering software on all new PCs. While many have resorted to digitally lashing out against Green Dam, Chinese artist and designer of the famous Bird's Nest at the Beijing Olympics, Ai Weiwei has decided upon a different approach. '[He wants] a general internet strike — no work, no games, no email or anything else online — for 24 hours on the date the government plans to require censorship software on all new computers, he says, will be a quiet act of rebellion. Not coincidentally, July 1 is the 88th anniversary of the Communist Party of China. Though he posted the idea, Ai wants to leave the meaning to those who participate. "I gave almost no explanation about why I'm doing it," Ai said. "I just give the structure and people will fill in their own meaning. I don't want to be political first. I wanted to set up an act that everyone can easily accept, and then realize the power later. I want people to see their own power," he said.'"

tramm writes "I've released an extension for the Canon 5D Mark II DSLR's video mode to enable functions that are useful for independent film makers. While the camera produces a great movie out of the box, the audio is a severely limited. My code adds features that should have been in the software, like on-screen stereo audio meters, live audio monitoring, reduced audio noise and crop marks for different formats. An introductory video shows the new features in use and an audio evaluation compares it to the stock firmware with very good results. It's similar to the incredibly flexible CHDK software for Canon's point-and-shoot cameras, but targeted at the film makers using the 5D. The Magic Lantern firmware is GPLed and new features will be written to make the camera even more useful on set. There is a wiki for documentation and development."

redlandmover writes "I already have an HP Media Server (upgraded processor, and memory) that has already been upgraded internally to 3.5TB. I'm sure everyone already has their favorite backup solution (RAID, WHS, a billion external hard drives, etc).

Hugh Pickens writes "Nature reports that the US military has abruptly ended an informal arrangement that allowed scientists access to data on incoming meteors from classified surveillance satellites, dealing a blow to the astronomers and planetary scientists who used the information to track space rocks. 'These systems are extremely useful,' says astronomer Peter Brown, at the University of Western Ontario. 'I think the scientific community benefited enormously.' Meteor data came from the Defense Support Program (DSP) satellite network consisting of infrared satellites in geosynchronous orbit to monitor the globe for missile launches or atmospheric nuclear blasts, forming the principal component of the United States' ballistic missile early-warning system. The satellites' effectiveness was demonstrated during Desert Storm, when DSP detected the launch of Iraqi Scud missiles and provided warning to civilian populations and coalition forces in Israel and Saudi Arabia. As a side benefit, the satellites could also precisely detect the time, position, altitude and brightness of meteors as they entered Earth's atmosphere, information the military didn't consider particularly useful, or classified. 'It was being dropped on the floor,' says former Air Force captain Brian Weeden. Although the reason for ending the arrangement remains unclear, Weeden notes that it coincides with the launch of a new generation of surveillance satellites and speculates that the Pentagon may not want details of the new satellites' capabilities to be made public, or it may simply lack the expensive software needed to handle classified and declassified data simultaneously. 'The decision may have been made that it was perhaps too difficult to disclose just these data.'"

UltraOne writes "Sprint requires your Social Security number in order to run a credit check before they will allow you to open an account, according to a store manager in Silver Spring, MD. Since Sprint is the exclusive carrier for the Palm Pre, if you are not willing to provide an SSN, you can't buy this product. I believe a full credit check for this level of consumer purchase is a clear example of overkill. I have supplied an SSN when buying a house and renting an apartment, but never for any other consumer purchase. I have purchased my cars with cash so far, so I don't have first-hand experience, but a car loan also seems to be an appropriate place to require an SSN for a credit check. At the very least, Sprint should have an alternative for people who don't want to give out their SSN. I also found the entire experience a powerful argument against exclusive license agreements." Read below for details of this reader's experience.
I was eager to purchase the Palm Pre to replace my aging Zire 72s, and also consolidate my PDA and mobile phone into a single device. Since reviews have generally been positive, I headed to my local Sprint store (8501 Fenton Street, Silver Spring, MD). My current mobile carrier is Verizon, so I also needed to set up service with Sprint.

The store had the Pre in stock, and the sale proceeded smoothly until the sales associate asked me for my Social Security number. He had already verified my identity with a driver's license. When I asked why the SSN was needed, he said it was to run a credit check. I offered a credit card instead, but he said that the SSN was required.

I asked to speak to the manager, who was a pleasant young woman, but not able to resolve the problem. She confirmed that Sprint required the SSN to run a credit check (through a credit bureau) before opening an account. I told her that I understood Sprint had an interest in making sure that I could pay for the service (I was planning to get the $70/month Everything Data 450 plan), but that I was concerned about identity theft and privacy. I offered several other options, including a check on my credit card limit, which is an order of magnitude greater than the combined price of the phone and two-year contract; placing the maximum deposit that Sprint requires from people with poor credit ($500); or pre-paying the entire two-year plan on the spot. None of these was acceptable options, so Sprint lost the sale.

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."

fiannaFailMan writes "An international plan to build a nuclear fusion reactor is being threatened by rising costs, delays and technical challenges. 'Emails leaked to the BBC indicate that construction costs for the experimental fusion project called Iter have more than doubled. Some scientists also believe that the technical hurdles to fusion have become more difficult to overcome and that the development of fusion as a commercial power source is still at least 100 years away. At a meeting in Japan on Wednesday, members of the governing Iter council will review the plans and may agree to scale back the project.' Iter will be a Tokamak device, a successor to the Joint European Torus (JET) in England. Meanwhile, an experiment in fusion by laser doesn't seem to be running into the same high profile funding problems just yet."

An anonymous reader writes "In a dangerous judgment for British bloggers and whistleblowers, a British court has ruled (absurdly) that because blogging itself is a public activity, bloggers have 'no reasonable expectation of privacy' regarding their identities, and newspapers are allowed to publish their identities if they can find them by fair or foul means. A British police detective who recently won the Orwell Prize for his excellent political writing used his blog to write highly critical accounts of police activities and unethical behavior, making very powerful enemies in the process. A well-funded newspaper with powerful connections quickly heard of his blog and decided it was absolutely vital to expose his identity using an investigative journalist. Like any good newspaper, the blogger anonymized the people and the locations in all the cases he discussed on his blog, but the newspaper alleges these were not sufficiently anonymized and complains that they could work out the identities, though British newspapers don't complain that they are allowed to publish the identities of men who are falsely accused of rape and cleared in court. The newspaper also helpfully contacted the blogger's employer, and his job is now threatened."

KentuckyFC writes "Scientists have found a way to join buckyballs together so that they form buckywires. The wires form when buckyballs are dissolved in an aromatic hydrocarbon called 1,2,4-trimethylbenzene. The solvent links the balls together to make wires shaped like a string of pearls, which then precipitate out. This relatively simple procedure opens the door to industrial-scale manufacture. Buckywires ought to be efficient light harvesters because of their great surface area and the way they can conduct photon-liberated electrons. But perhaps the area of greatest interest is drug delivery. The researchers suggest that buckywires ought to be safer than carbon nanotubes because the production method is entirely metal-free. This contrasts with the production of nanotubes, which are formed in a reaction catalyzed by metallic nanoparticles."

Seal writes "Erlang, originally created at Ericsson in 1986, is a functional programming language which was released as open source around 10 years ago and flourished ever since. In this Q&A, Erlang creator Joe Armstrong talks about its beginnings as a control program for a telephone exchange, its flexibility and its modern day usage in open source programs. 'In the Erlang world we have over twenty years of experience with designing and implementing parallel algorithms. What we lose in sequential processing speed we win back in parallel performance and fault-tolerance,' Armstrong said. He also mentions how multi-core processors pushed the development of Erlang and the advantages of hot swapping."

Al writes "Two researchers have found a way to run unauthorized code on an iPhone remotely. This is different than 'jailbreaking,' which requires physical access to the device. Normally applications have to be signed cryptographically by Apple in order to run. But Charles Miller of Independent Security Evaluators and Vincenzo Iozzo from the University of Milan found more than one instance in which Apple failed to prevent unauthorized data from executing. This means that a program can be loaded into memory as a non-executable block of data, after which the attacker can essentially flip a programmatic switch and make the data executable. The trick is significant, say Miller and Iozzo, because it provides a way to do something on a device after making use of a remote exploit. Details will be presented next month at the Black Hat Conference in Las Vegas." The attack was developed on version 2.0 of the iPhone software, and the researchers don't know if it will work when 3.0 is released.

KentuckyFC writes "Black holes are thought to form when a star greater than 4 times the mass of the Sun explodes in a supernova and then collapses. The force of this collapse is so great that no known force can stop it. In less massive stars, the collapse cannot overcome so-called neutron degeneracy, the force that stops neutrons from being squashed together. Now a Russian physicist says another effect may be involved. He points out that quantum chromodynamics predicts that when neutrons are squashed together, matter undergoes a phase transition into "subhadronic" matter. This is very different from ordinary matter. In subhadronic form, space is essentially empty. So the phase change creates a sudden reduction in pressure, forcing any ordinary matter in the star to implode into this new vacuum. The result is a massive increase in temperature of this matter that creates a "burning wall" within the supernova. And it is this burning wall that stops the formation of a black hole, not just the degeneracy pressure of neutrons. This should lead to much greater energies inside a supernova than had been thought possible until now. And that's important because it could explain the formation of high energy gamma ray bursts that have long puzzled astrophysicists."

Hugh Pickens writes "The CIA is adopting Web 2.0 tools like collaborative wikis but not without a struggle in an agency with an ingrained culture of secrecy. 'We're still kind of in this early adoptive stage,' says Sean Dennehy, a CIA analyst and self-described 'evangelist' for Intellipedia, the US intelligence community's version of the popular user-curated online encyclopedia Wikipedia adding that 'trying to implement these tools in the intelligence community is basically like telling people that their parents raised them wrong. It is a huge cultural change.' Dennehy says Intellipedia, which runs on secure government intranets and is used by 16 US intelligence agencies, was started as a pilot project in 2005 and now has approximately 100,000 user accounts and gets about 4,000 edits a day. 'Some people have (supported it) but there's still a lot of other folks kind of sitting on the fence.' Dennehy says wikis are 'a challenge to our culture because we grew up in this kind of "need to know" culture and now we need a balance between "need to know" and "need to share."' A desire to compartamentalize information is another problem. 'Inevitably, every person, the first question we were asked is "How do I lock down a page?" or "How do I lock down a page so that just my five colleagues can access that?"' The growth of Intellipedia has so far largely been fueled by early adopters and enthusiasts says Chris Rasmussen, a social-software knowledge manager and trainer at the National Geospatial Intelligence Agency. 'We are struggling to take it to the next level.'"

Hugh Pickens writes "The Register reports that a longtime Wikipedia admin has been caught offering to edit the online encyclopedia in exchange for cash. Someone noticed a post to an online job marketplace where he was advertising his services: 'Besides technical writing, I also am an accomplished senior Wikipedia administrator with several featured articles to my name,' read the post, which has since been changed. 'If you need a good profile on Wikipedia, I can help you out there too through my rich experience.' Wikipedia promptly opened a discussion page to try to reach consensus on the community view of 'paid editing.' So far opinion seems to be divided between those who say it's ok as long as full disclosure is made and 'edits are compliant with WP:NPOV, WP:RS, WP:BLP, WP:N,' and others who believe that paid editing automatically creates a conflict of interest. Back in 2006, Wikipedia co-founder Jimmy Wales shot down a company known as MyWikiBiz, which promised that you could 'author your legacy on the Internet.' The company subsequently had to reinvent itself with no reference to Wikipedia. 'It is not ok with me that anyone ever set up a service selling their services as a Wikipedia editor, administrator, bureaucrat, etc., I will personally block any cases that I am shown,' wrote Wales."

1 a bee writes "Ars Technica is running a story by Matthew Lasar about how Disney's ESPN360.com is charging ISPs for 'bulk' access to their content. According to the article, if you visit ESPN using a 'non-subscribing' ISP, you're greeted with a message explaining why access is restricted for you. This raises a number of issues: '... it's one thing to charge users an access fee, another to charge the ISP, potentially passing the cost on to all the ISPs subscribers whether they're interested in the content or not.' Ironically, the issue came to the fore in a complaint from the American Cable Association (ACA) to the FCC. A quoted ACA press release warns, 'Media giants are in the early stages of becoming Internet gatekeepers by requiring broadband providers to pay for their Web-based content and services and include them as part of basic Internet access for all subscribers. These content providers are also preventing subscribers who are interested in the content from independently accessing it on broadband networks of providers that have refused to pay.' So, is this a real threat to net neutrality (and the end-to-end principle) or just another bad business model that doesn't stand a chance?"

An anonymous reader was one of several to write with this news: "The French 'Conseil Constitutionnel' just ruled that the recently voted 'Hadopi' law, which enforces a 'three strikes and you're out' system, is actually unconstitutional [article in French; here's an English-language article at Ars]. They mainly make two points: 1) They argue that removing Internet access is equivalent to hindering a person's freedom of speech, and as such can only be decided by appointed judges. This removes all punitive power from the administrative body supposed to enforce the three-strikes rule; all it can do now is warn you that 'they're watching you.' 2) When illegal filesharing is detected, users have to prove their innocence. This is obviously contrary to the constitutional principle of presumption of innocence."

KentuckyFC writes "One of the many curious properties of Bose Einstein Condensates (BECs) is that the flow of sound through them is governed by the same equations that describe how light is bent by a gravitational field. Now, a group of Israeli physicists have exploited this idea to create an acoustic black hole in a BEC. The team created a supersonic flow of atoms within the BEC, a flow that prevents any phonon caught in it from making headway. The region where the flow changes from subsonic to supersonic is an event horizon, because any phonon unlucky enough to stray into the supersonic region can never escape. The real prize is not the acoustic black hole itself but what it makes possible: the first observation of Hawking radiation. Quantum mechanics predicts that pairs of phonons with opposite momentum ought to be constantly springing in and out of existence in a BEC. Were one of the pair to stray across the event horizon into the supersonic region, it could never escape. However, the other would be free to go on its way. This stream of phononic radiation away from an acoustic black hole would be the first observation of Hawking radiation. The team hasn't gotten that far yet, but it can't be long now before either they or their numerous competitors make this leap."

eldavojohn writes "The Hubble Constant is used for many things in astrophysics: from determining how fast things are moving away from us, to the total volume of the universe, to predicting how our universe will end. The current best value for the Hubble Constant is 74.2 ± 3.6 (km/s)/Mpc according to recent conventional methods and the recently restored Hubble Telescope. Most astronomers agree that that's within 10% of its actual value. Researchers now claim that they might be able to get to 3% using water molecules in galactic disks to act as masers that amplify radio waves, to analyze galaxies seven times as far away as the current measurements. The further away the 'standard candle' is, the more assured they can be that local effects are not skewing the measurements. From one of the researchers: 'We measured a direct, geometric distance to the galaxy, independent of the complications and assumptions inherent in other techniques. The measurement highlights a valuable method that can be used to determine the local expansion rate of the universe, which is essential in our quest to find the nature of dark energy.' Once the Square Kilometer Array is completed, they hope to get even closer to the actual value."

wandazulu writes "Forty years ago this summer, Ken Thompson sat down and wrote a small operating system that would eventually be called Unix. An article at ComputerWorld describes the history, present, and future of what could arguably be called the most important operating system of them all. 'Thompson and a colleague, Dennis Ritchie, had been feeling adrift since Bell Labs had withdrawn earlier in the year from a troubled project to develop a time-sharing system called Multics (Multiplexed Information and Computing Service). They had no desire to stick with any of the batch operating systems that predominated at the time, nor did they want to reinvent Multics, which they saw as grotesque and unwieldy. After batting around some ideas for a new system, Thompson wrote the first version of Unix, which the pair would continue to develop over the next several years with the help of colleagues Doug McIlroy, Joe Ossanna and Rudd Canaday.'"

Ant sends in a story at CNet about the evolution of downloadable console games, ranging from Intellivision's PlayCable in 1981 to the modern systems we see today. Quoting: "Intellivision was the first home console to let users download games via a coaxial cable line. Subscribers rented a special cartridge that hooked up to local cable and would be able to download single games that could be played until users decided to download new titles. The service's downfall was a result of innovations to Mattel's Intellivision game system, which began using cartridges with ever-increasing amounts of memory. The PlayCable service could no longer keep up, since the special cartridge could hold only a fourth of the total space that newer games required."

So far, 32% responding actually think that internet voting is worth it, risks and all. It is scary how easily people can be persuaded to trust a system that is so vulnerable."

Bryant writes "Scientists with the Carnegie Institution for Science have discovered what could bring yet another massive advance in memory and storage. The discovery, a magnetoresistence literally 'up to 1000 times more powerful' than the Giant Magnetoresistence Effect discovered roughly 20 years ago, which led to one of the major breakthroughs in memory, seems to be a result of high-pressure interactions between Manganites. Manganites aren't new to this game; MRAM uses Manganite layers to achieve the Magnetic Tunnel Effect needed to keep the state of memory stable. Applying significant amounts of pressure to known tech-useful materials isn't a new trick; you might recall the recent breakthrough with Europium superconductivity thanks to similar high-pressure antics."

There is also a $1 million bonus to anyone who can get a picture of a man-made object on the moon. But one archeologist believes that 'The sites of early lunar landings are of unparalleled significance in the history of humanity, and extraordinary caution should be taken to protect them.' He's concerned that we may end up with rover tracks destroying historic artifacts, such as Neil Armstrong's first bootprint, or that a mistake could send a rocket slamming into a landing site. He calls on the organizers to ban any contestant from landing within 100KM of a prior moon landing site. Now he seems to think this just means Apollo. What about the Luna and Surveyor landers? What about the Lunokhod rovers? Are they fair game?"

According to the article, 'copies of the 'Moniac,' as it became known in the United States, were built and sold to Harvard, Cambridge, Oxford, Ford Motor Company and the Central Bank of Guatemala, among others.' There is a cool video of the computer in operation at Cambridge University. I remember that the Instrumentation Lab at MIT still had an analog computer in its computer center in the mid-1970s. Even then, it seemed archaic, and now this form of computation is largely forgotten. With 14 machines built, it must have been one of the more successful analog computers — a supercomputer of its day. Of course, you have to wonder if it could have been used to predict our current economic difficulties."

BrianWCarver writes "The San Francisco Business Times covers a study by student researchers at UC Berkeley's School of Information pointing up the massive holes in privacy policies and protections of which US companies take advantage. The researchers have released a study and launched a Web site, knowprivacy.org, in which they found that Web bugs from Google and its subsidiaries were placed on 92 of the top 100 Web sites and 88 percent of the approximately 394,000 unique domains examined in the study. This larger data set was provided by the maintainer of the Firefox plugin Ghostery, which shows users which Web bugs are on the sites they visit. The study also found that while the privacy policies of many popular Web sites claim that the sites do not share information with third parties, they do allow third parties to place Web bugs on their sites (which collect this information directly, typically without users' knowledge) and share with corporate 'affiliates.' Bank of America, to take one extreme example, has more than 2,300 affiliates — and users cannot learn their identities. The full report and more findings are available from their Web site."

We mentioned on Thursday that Wikipedia has banned edits originating from certain IP addresses belonging to the Church of Scientology; reader newtley writes now that Scientology leader (CEO and Chairman of the Board of the linked, but legally separate, Religious Technology Center) David Miscavige calls the ban "a 'despicable hate crime,' and asks, 'What's next, will Scientologists have to wear yellow, six-pointed stars on our clothing?' During World War II, Hitler forced Jewish men, women and children to wear a a yellow cloth star bearing the word Jude to brand them in the streets of Europe, and in the Nazi death camps."

PCP is an enterprise-class open source system monitoring, measurement, and visualization infrastructure — overlooked in last fall's monitoring tool discussion. Since its proprietary beginning in 1993, PCP has been re-released as open source and ported to all major operating systems. Readers of Slashdot's recent Beginning Python Visualization book review will be pleased to hear there are Python interfaces to PCP data sources. Here is an example of using Python and Blender to visualize PCP data (registration may be required). The PCP dev community is well and active, and includes several of the original team members."

The new gateway is written entirely in Ruby (using the Merb framework) and the Git repository can be found here. We are looking for open source help with supporting other phone types and translations into new languages. Currently 8 languages are supported, but we'd like to support all languages Wikipedia supports. This is an active project and we are looking for new features, etc. from the community."

aceydacey writes "Sometimes a picture is worth a thousand words. Beginning Python Visualization: Creating Visual Transformation Scripts, published in February 2009 by Apress, shows how Python and its related tools can be used to easily and effectively turn raw data into visual representations that communicate effectively. The author is Shai Vaingast, a professional engineer and engineering manager who needed to train scientists and engineers to do this kind of programming work. He was looking for a tutorial and reference work, and unable to find a suitable text, wound up writing his first book. He writes in the easy and clear style of someone comfortable and engaged with the subject matter." Keep reading for the rest of aceydacey's review. Beginning Python Visualization: Crafting Visual Transformation Scripts author Shai Vaingast pages 363 publisher Apress rating 9/10 reviewer aceydacey ISBN 1430218436 summary learn how to process, organize, and visualize data from various sources using the Python language The book uses several very specific examples that illustrate general principles.

The first example is using GPS data. By using Python one can extract data from GPS receivers and enter it into the computer and manipulate it to do what one wants including creating graphs and charts. In this section he shows how to use CSV, comma separated values, as a most useful file format. He shows show to extract data from real world GPS devices and import it via serial ports and the PySerial module. It would be easy for the reader to duplicate and extend this project.

The heart of the book is coverage of useful examples utilizing MatPlotLib, NumPy and SciPy. These related tools are easy to use and fully integrated with Python. MatPlotLib is for plotting data and graphs, including interactive graphs and image files. NumPy is a powerful math library comparable to commercial tools like MatLab, and SciPy extends NumPy to for the sciences. Examples are numerous and include signal analysis using Fourier transforms.

There is also a section on Image Processing using PIL, the Python Imaging Library. This is used for relatively simple image cropping and sizing and also for bit by bit image processing. Interpolation and curve fitting are also well covered. For anyone wanting an introduction to graphical analysis of statistical data, this would be an excellent resource.

The author is obviously a professional in this field. He has a knack for good organizational style and a pragmatic approach to the work. In the book he says "Most of the time, research is organized chaos. The emphasis, however, should be on organized, not chaos." A real value I got from the book is a better understanding of data files, format, and organization as well as methods and guidelines for selecting file formats and storing and organizing data to enable fast and efficient data processing. It is obvious that this book was written by a practicing engineer.

The theme of the book is that Python can be an all purpose environment for data manipulation and visualization, using nothing but free and open source tools that are easily integrated and scriptable without using multiple programming languages. The book should be an invaluable tool for scientists and engineers but it is also easily accessible to anyone interested in math and data analysis. There is no need for an advanced math background. While, as a matter of full disclosure, I have undergraduate degrees in Math and Physics, I feel the book should be easily accessible to anyone with a solid high school math background who is seriously interested in the subject. The book contains a short introductory tutorial on the basics of Python so anyone familiar with programming in any language should be fine.

The book is an easy read from front to back, and I am sure it will also be a good reference resource for the future. The writing style is very clear and unforced and I found surprisingly few errors. While the Python world has a surplus of introductory and general books, books covering this kind of specific domain are especially welcome, and we could use more on other topics by competent authors.

At 363 pages the book is a surprisingly fast read. Its methodology is to use specific, short code examples to make all the key points. Most of the code samples are well selected, short and written in clear, concise Python. This is not the kind of book that overwhelms you with massive amounts of code. Either the book was well edited or else it was written by an exceptionally lucid thinker, or both.

So, if you want to learn how to process, organize, and visualize data from various sources using the Python language, I recommend this book to you. I have also posted a podcast of an interview with the author at Python411

KentuckyFC writes "We're all familiar with GPS. It consists of a network of satellites that each broadcast a time signal. A receiver on Earth can then work out its position in three-dimensional space by comparing the arrival times of the signals from at least three satellites. That's handy, but it only works on Earth. Now astronomers say that the millisecond signals from a network of pulsars could allow GPS-style navigation on a galactic scale. They propose using four pulsars that form a rough tetrahedron with the Solar System at its center, and a co-ordinate system with its origin at 00:00 on 1 January 2001 at the focal point of the Interplanetary Scintillation Array, the radio telescope near Cambridge in the UK that first observed pulsars. The additional complexity of working with signals over these distances is that relativity has to be taken into account (which is why the origin is defined as a point in space-time rather than just space). The pulsar GPS system should allow users to determine their position in space-time anywhere in the galaxy to within a few nanoseconds, which corresponds to an accuracy of about a meter." Pulsars slow down over time, and the arXiv paper doesn't seem to mention this. The paper is mainly about establishing a coordinate system and a reference selection of pulsars. Any proposed Galactic Positioning System would have to take the slowing into account, and since it is poorly understood and not completely predictable, this would limit accuracy.

simoniker writes "Over at Gamasutra, there's a massive new interview with Epic (Mega)Games founder Tim Sweeney, the guy who's still a key technical figure at the Unreal Engine/Gears Of War developer. He discusses his early programming days, the story behind classic shareware game/tool ZZT, the origins of Epic, the '90s shareware business, and even a bit about the future as well. Particularly neat is his revelation that you can still order ZZT via mail, with orders fulfilled by his dad: 'My father still lives at the address where Potomac Computer Systems started up, so he still gets an order every few weeks... he's retired now, so he doesn't have much to do. Every week, he'll just take a stack of a few orders, put disks in them, and mail them out.'"

Hugh Pickens writes "New Scientist reports that instead of identifying chemicals that could point to life, NASA's robot explorers may have been toasting them by mistake. Even if Mars never had life, comets and asteroids that have struck the planet should have scattered at least some organic molecules over its surface but landers have failed to detect even minute quantities of organic compounds. Now scientists say they may have stumbled on something in the Martian soil that may have, in effect, been hiding the organics: a class of chemicals called perchlorates. At low temperatures, perchlorates are relatively harmless but when heated to hundreds of degrees Celsius perchlorates release a lot of oxygen, which tends to cause any nearby combustible material to burn. The Phoenix and Viking landers looked for organic molecules by heating soil samples to similarly high temperatures to evaporate them and analyse them in gas form. When Douglas Ming of NASA's Johnson Space Center in Houston, Texas, and colleagues tried heating organics and perchlorates like this on Earth, the resulting combustion left no trace of organics behind. "We haven't looked the right way," says Chris McKay of NASA's Ames Research Center. Jeffrey Bada of the University of California, San Diego, agrees that a new approach is needed. He is leading work on a new instrument called Urey which will be able to detect organic material at concentrations as low as a few parts per trillion. The good news is that, although Urey heats its samples, it does so in water, so the organics cannot burn up."
