Otter writes "A study at MIT has found that aluminum foil headwear ("Among a fringe community of paranoids..the protective measure of choice against invasive radio signals") actually amplifies certain frequency bands allocated to the US government, as well as a mobile phone range, and is largely ineffective through the rest of the radio spectrum. But we can we trust the study, or are They controlling the researchers?"

$random_var asks: "I am an undergraduate student currently studying Bioengineering. However, I am growing more and more interested in programming and linguistics, which leads me to think that I should define my own major, Computational Linguistics [mit.edu], which google defines as 'a field concerned with the processing of natural language by computers.' When I present my proposal for this degree to the school's advising staff, I would like to have a complete list of all of the topics this major should cover. Having only little experience with computer science and engineering, I'm not sure what parts of that field I should include. Beyond the basic lower-division courses, what specific fields of computer science do you think should be emphasized in a practical undergraduate study of Computational Linguistics?"

roach2002 writes "Carnegie Mellon University is fighting back against a requirement that taps on campus internet access must be quickly obtainable. The technology that would allow the FBI to monitor internet access, after a court order, "at the flip of a switch" would cost at least $450 per student. MIT is also covering the story." From the article: "'The Department of Justice wants 24/7 access, whenever they need it, and they want remote access. We find that too extremely burdensome in terms of money, staff, and technology,' said Maureen McFalls, Director of Government Relations for Carnegie Mellon and the coordinator of Carnegie Mellon's response to this issue. According to an ACE press release, the cost to universities could be upwards of $7 billion, or at least $450 extra on each student's tuition bill."

cynical writes "Harvard's Ethan Zuckerman, founder of GeekCorps and Global Voices, got a chance last week to drop in on Nicholas Negroponte and get a preview of the $100 laptop Negroponte has designed for students in the developing world. Zuckerman talks about both its hardware and the One Laptop Per Child project, and asks the readers for suggestions for innovative ways the $100 laptop can be used." From the article: "The mockup I saw was about the size of a large paperback book. There's a stiff rubber gasket around the edge of the machine, which can double as a stand. The keyboard on the mockup was detachable, but will probably fold out on a hinge ... Two trackballs, surrounded by four way buttons, on each side of the screen act as controls, and function keys on the back act as additional buttons.)" We've previously reported on this device here on Slashdot.

Werner Heuser writes "Ancient Greek and Roman historians recorded that during the siege of Syracuse in 212 BC, Archimedes (a notably smart person) constructed a burning glass to set the Roman warships, anchored within bow and arrow range, afire. The story has been much debated and oft dismissed as myth ... Intrigued by the idea and an intuitive belief that it could work, MIT's 2.009ers decided to apply the early product development 'sketch or soft modeling' process to the problem."

An anonymous reader writes "The Nobel Prize in Chemistry for 2005 has been jointly awarded to Robert H. Grubbs (California Institute of Technology), Richard R. Schrock (Massachusetts Institute of Technology), and Yves Chauvin (Institut Français du Pétrole) for the development of the metathesis method in organic synthesis." Advanced [PDF] and supplementary [PDF] information is also available from the Nobel Prize site.

photonic writes "The World Solar Challenge has just finished the first racing day. It is a 3000 kilometer race from Darwin to Adelaide for cars that are powered by solar energy only. The results from this day have not yet been published, but intermediate results suggest that the Dutch Nuon Solar Team is again on the lead. This team from Delft University of Technology has a reputation to uphold since they also won the previous two races in 2001 and 2003, the last one in a record breaking 97 km/h average. The Tesseract team from MIT was less fortunate: during the qualification they got off track and rolled over. After some fixing up they still managed to qualify into 7th place on battery power, but with substantial damage to the solar panel their challenge will be finishing rather than winning."

markmcb writes "While some of us cling tight to our memories of Apple-filled classrooms playing The Oregon Trail and driving our Turtle around in Logo, children today have many other ways to learn about the inner-working of computers and the code that drives them. Wired.com is running an interesting article about a boardgame in which players must use simple logic similar to that used in programming to get their skier down the mountain. From the article: 'Using basic math, players have to figure out which paths are open to them and then decide the fastest way to the finish line. The trick, however, is learning which paths are open to you using only programmer jargon like 'if (X==1)' then you can take the green path or 'while (X4) you can take the orange path,' where X is the roll of the die.'"

karvind writes "BBC is running an interesting story about the I/O Brush developed by Kimiko Ryokai, researcher at the MIT Media Labs. The device allows a person to pick up colours and textures from their environment and paint with them on a large digital screen. At the tip of the brush is a tiny video camera enclosed by a ring-shaped brush. LEDs are used for illumination, and pressure sensors to trigger image capture. The camera captures one frame in the normal mode, and a few seconds of video in movie mode. The brush "paints" the captured image or movie onto a back-projected touch screen."

stlhawkeye writes "MIT researchers with the Mobile Landscape Projects have mapped a city based on cell phone usage. The article includes a map of Graz, Austria with a color-coded overlay indicating cell phone usage in various parts of the city. Using call origin and destination data, they are able to not only reverse-engineer a topographic map of the geography and landscape, but one of phone usage as well. The implications of the research have practical applications in law enforcement, emergency management, and traffic management. There are also, of course, privacy implications."

jose parinas writes "Researchers at MIT made the first radio detection of deuterium, an atom that the scientists claim is key to understanding the beginning of the universe." It turns out the actual detection wasn't the key, but filtering out all of the RF 'pollution' produced by nearby gadgets.

An anonymous reader writes "This weekend the 8th Annual Autonomous Underwater Vehicle (AUV) Competition was held in San Diego. This year teams were challenged to complete three tasks including finding a docking station, inspecting a pipeline, and surfacing in a recovery zone marked by an acoustic pinger. Teams from MIT, Cornell, Duke and sixteen others competed for the grand prize. After an intense final round, the University of Florida's Team SubjuGator dethroned MIT and walked away with the victory. Interestingly, the UF team ran Windows XP on their embedded computer."

SimilarityEngine writes "Physicists at MIT have developed a new kind of nanophotonic waveguide, overcoming 'several long-standing obstacles' to move us one step closer to optical computers. Photonics strives to improve on electronics in terms of space requirements, speed and energy consumption - but until recently, it was not possible to perform well in all three areas simultaneously. In their paper, John Joannopoulos et al. demonstrate how to reliably encode a signal as surface plasmons which side-steps such limitations."

Slashback (below) brings another round of updates and clarification to recent and continuing stories here on Slashdot. This evening, there's more video of the recent space shuttle launch, a reminder about the other 10th planet, an encouraging update about open source medical software, another approach to structure-as-PC-enclosure, and more. Read on for the details. Shuttle launches are easier to fake than moon landings. Rex Ridenoure writes "Shuttle External Tank RocketCam video highlights from the STS-114 'Return to Flight' launch on July 26 have been posted on Ecliptic's website. Ecliptic supplied this RocketCam system to ET builder Lockheed Martin Michoud [Louisiana] Operations. A slow-motion clip of the now-famous ET foam shedding event has been inserted at the time it occurred -- about 1:40 after liftoff.

Still on the 'things in space' front: Sedna isn't nearly as sexy a name. Martian Anthropologist writes, of the recently announced discovery of a tenth planet in our solar system, "Actually, there's good reason to say that this is really the 11th planet, not the 10th. Another large body, now named Sedna, was discovered last year. It is slightly smaller than Pluto."

(Here's some earlier coverage of Sedna on Slashdot.)

Software for the Commonwealth. Aaron writes "As a followup to a recent story about the U.S. Government giving away its Electronic Medical Record Software, a small practice of physicians describes their experience transitioning from paper to electronic charts. Not everything goes well, from training staff to use Windows XP and tablet computers to viruses that crash their system to physicians complaining about being relegated to data-entry clerk status. In the end, however, they would never go back to paper.

From the article:'"Doctor, do you find you are spending more time interacting with the computer than with your patients?" For a while, the answer was clearly yes.'"

Aw, shucks, he might have done it anyhow. David writes "Thanks to my Ask Slashdot porting query, Ryan Gordon (aka icculus), the man who ported Unreal Tournament and many other popular games to Linux, is going to be working on the Linux version of Lugaru. It should be ready soon!"

You have to watch the quiet types, and never let them near your obscure hardware. jschauma writes "About a month ago, NetBSD made a Plea for 'Cold, Hard Cash', a Call for Donations. The results were very positive: an impressive $27K were donated since then, allowing the NetBSD Foundation to purchase five new machines; three of those machines will be added to the nightly build infrastructure and two of those machines will become anonymous cvs servers. See Christos Zoulas's email for detailed specifications of the hardware, and feel free to continue the donations!"

Definitely not for snowboarding helmet cam use. The CVS one time use camcorder has now been hacked so that videos can be downloaded over USB -- no need to desolder the flash memory.

How to spot a future writer-of-Federal-grants. Jason Schroeder writes "The recent story on the guy who put a Mac Mini in the wall reminded me of something I'd seen a while back: The Parabolic Heat Transference Case Mod for his Red Hat server. Pretty good idea with lots of scientific tidbits to make it interesting."

Hey, these fakes are a bunch of phoney frauds! strib writes "Remember SCIgen, the program that randomly-generated an accepted paper at WMSCI 2005? Well, thanks in part to the generous donations of Slashdotters, we made it down to the conference and gave a session full of fake talks. And it's all on video. Thanks to everyone who helped!"

An anonymous reader writes "Wired News reports that cell phones were used in a recent project at MIT to both document and predict the lives of 100 MIT faculty and staff members. During the Reality Mining Project at MIT, Researcher Nathan Eagle logged 350,000 hours of data over nine months about the location, proximity, activity and communication of volunteers through cell phones carried by the participants. From the article, "Given enough data, Eagle's algorithms were able to predict what people -- especially professors and Media Lab employees -- would do next and be right up to 85 percent of the time."

BishopBerkeley writes "Nature has an interesting nugget about the second meeting of the Image and Meaning Initiative which was held at the Getty Museum in Los Angeles. It is about the use of graphics in presenting scientific data. I am also a big advocate of using nice graphics in scientific presentations, but I also agree with Felice Franel, the founder of I-M, that not all images are meaningful scientifically. In fact, one encounters (and I am ashamed to admit that I have published) images that look nice but have no scientific import at all. One very cool Harvard physics professor, Eric Heller, produces wickedly beautiful (and meaningful) images of quantum mechanical models. These images have made the covers of Science and Nature, and are featured in his online art gallery, which was reviewed in the New York Times in 2002." And of course, any mention of graphic information should not go by without a big shout out to Edward Tufte.

Ninwa writes "According to the MIT news office the folks in their labs have really outdone themselves this time, they've created a new form of matter. The post states, 'They have become the first to create a new type of matter, a gas of atoms that shows high-temperature superfluidity.' It has been said that this could solve the mysteries in superconductivity."

Will Stewart writes "You have doubtless read that Silicon Valley Watcher reported on Google plans to use trucks equipped with lasers and digital photographic equipment to create a realistic 3D, online version of San Francisco and eventually other major US cities, but you may not have seen the picture of where the trucks are kept and Berkeley's unrelated research project and published technical research (PDF file)."

Cory R writes "Neil Gershenfeld is an MIT professor and the director of MIT's Center for Bits and Atoms where he teaches a course called "How to Make (almost) Anything." In his book FAB: The Coming Revolution on Your Desktop--From Personal Computers to Personal Fabrication, Gershenfeld describes the current state of personal fabrication tools and the surprising impact that these tools have when made available to everybody from MIT students to villagers in India in the form of Fab Labs. Lots of fabrication techniques and some technologies are discussed including those that are still only in development today. The pace of development seems to be accelerating and as the capabilities of the tools advance, Gershenfeld predicts one day he will be able to drop the word "almost" from the title of his course." Read on for the rest of Cory R's review. FAB: The Coming Revolution on Your Desktop--From Personal Computers to Personal Fabrication author Neil Gershenfeld pages 278 publisher Basic Books rating 8/10 reviewer Cory R ISBN 0465027458 summary Personal fabrication may do for the real world what personal computers have done for the virtual world- let you have what you want when you want it.

I first heard of Gershenfeld and this book after listening to a podcast of a discussion he participated in at the O'Reilly Emerging Technology Conference. I'm a programmer by day but in my pre-parenthood days, I played with a bunch of microcontrollers and simple robotics-related hardware (mostly motors and sensors). The idea of being able to fabricate anything I could think of appealed to me instantly.

Gershenfeld asserts that personal fabrication tools are developing along a path very similar to the one taken by computers. Computers were once large, expensive, complicated machines accessible only to skilled operators. Now they are much more accessible and have evolved to the point that most people can make use of them to some degree. Machine tools, at best, are still at the mainframe-stage of evolution but that is changing rapidly. What happens when machine-building machines, which can manipulate atoms and molecules, are as accessible as computers are today?

Well, it turns out that machines already on the market can give you a pretty good sense of what's in store. While not quite at the level of Star Trek replicators or Nutri-Matic dispensers from the Hitchhiker's Guide to the Galaxy (both, oddly enough, seem to be mostly used to make tea or something almost, but not entirely, unlike tea), fabrication machines are getting smaller, and cheaper. Some of the tools discussed in the book include:

• desktop milling machines : affordable
• sign cutters : novel uses including cutting copper sheets into traces for circuit boards
• laser cutters : very expensive
• waterjet cutters : very expensive but extremely useful
• 3D printers : expensive and slow, but very cool
• functional material printers : print resistors and capacitors into circuits a layer at a time
• microcontrollers : powerful and cheap
• CAD software : difficult to use
• CNC machines : expensive, difficult to use

All of these tools are available to some degree but most are very expensive and all are quite complicated to use.

The longest section of the book is called "The Present". The section is about the current state-of-the-art and it alternates between a chapter of anecdotes and project descriptions and a chapter on some aspect of fabrication (e.g. cutting tools, CAD software, electronics, etc...). By keeping the practical or social discussion next to the technical discussion, Gershenfeld makes what could be dry technical details accessible and engaging. It makes the book and the central ideas accessible even to (or perhaps especially to) non-technical readers.

In fact, the author has been very careful to not include too much technical detail in the text of the book. There are notes at the end with slightly more info, and a pointer to a website with some of the actual schematics and Python source code, but it is still very frustrating for a technically inclined reader who immediately wants to dial in on some of the details. The book will age better because of this, but it will send many Slashdotters running to their favorite search engine looking for more information.

The book includes a lot of illustrations and diagrams. They are all in black and white but have an inconsistent presentation. Sometimes the photos are presented on a weird background that looks like a network of circles and squares while others have no background. There are several photographs of circuits that do not add anything other than to show you how simple the circuit is (often just a microcontroller and a couple of other components). You usually cannot even make out what the individual components are or how anything is wired up. There are many photos of the people at the center of the stories and those pictures do manage to convey a sense of the awesome impact the tools have.

So, what's missing from the book? Personally I would have liked to see the technical appendix greatly expanded. I understand that this information doesn't age well and I'm guessing the author (or wise editor) didn't want to elaborate on the technical details for that reason. Fab is written for a very general and broad audience. Enough technical details are presented to keep the geeks reading, but it mostly wouldn't discourage a non-technical reader with the possible exception of the chapter on electronics. For a lot of Slashdot readers, the book definitely leaves you wanting more.

The chapters are generally under 20 pages each and the writing is fluid and simple. The book has a table of contents and a comprehensive index and even though Gershenfeld doesn't cite other publications in the text, I would have loved to see a bibliography or other list of materials that expand on the topic of personal fabrication. A few pointers from the author to complementary material would have been appreciated. The book definitely piqued my interest and fortunately, a little research has shown this to be a very active subject.

The book ends with a rather defensive look forward. There are many who feel self-reproducing machines could basically take over the planet. Gershenfeld acknowledges this and answers with his belief that any negative technologies that emerge will be fought with countermeasures, like the virus-antivirus battle on modern PC's. It's pretty much inevitable that evildoers will acquire this technology, but Gershenfeld is optimistic that fab labs can help address the root causes for conflict, largely assuaging any threat.

In summary, if the idea of having your own replicator is appealing (hello tea lovers!) or if you are interested in a new approach to giving people around the globe the tools they need to help themselves, then you will enjoy and likely be inspired by this book. Just be prepared to look elsewhere for the minutiae. I rate this book an 8/10.

Slashback is back from vacation with updates on the Apple switch to Intel,a now-fixed glitch in the recent release of Debian 3.1, a hyper-efficient Honda, and the real numbers on online music networks. Read on for the details.

It still feels like a strange dream that they're really switching. An anonymous reader writes "With our latest Unix (MacOS-X) vendor's switch to x86, I figured now would be a fine time to revisit an old MIT Graduate Student Beer announcement from 2001."

This is a similar technique to the one that Microsoft used to make sure Linux could not be loaded on Xbox..." I'm still not sure how they'll do this with an open source Kernel." They're clearly part of the Linspire marketing effort, but Robertson's messages, including this one, are usually pithy and worth reading.

Frank Buss writes "Common Lisp is an ANSI standard, which defines a general purpose language and library, and is implemented by free and commercial compilers and IDEs; see *hyper-cliki* for more general information about Common Lisp. The book Practical Common Lisp explains the language with many practical examples and is available in full text online, too." Read on for the rest of Buss' review. Practical Common Lisp author Peter Seibel, Gary Cornell (Editor) pages 500 publisher Apress rating 8 reviewer Frank Buss ISBN 1590592395 summary A book for learning and using Common Lisp

Unlike other good books about Lisp, which are focused on a specific domain, like AI (such as Paradigms of Artificial Intelligence Programming ) or basic computer science (for example Structure and Interpretation of Computer Programs for the Lisp-like language Scheme), this book focuses on solving real-world problems in Common Lisp, like web programming, testing etc., after introducing the language by examples in the first chapters. I started with Lisp half an year ago, and it has helped me a lot in learning it. But even if you already know Lisp, this book may be useful for you, because it has a fresh view on the language and the examples in the later chapters are usable in your day-to-day work as a programmer.

The first chapter tells you something about the author (he was a good Java programmer before starting with Lisp) and the history of Lisp and Lisp dialects like Scheme. The next chapters are a tour through all Lisp features, written in easy-to-understand steps, beginning with the installation of a Lisp system and an introduction to the interactive REPL. You don't need any experience in other languages to understand it.

The general concept throughout is to explain a feature first, then show an example of how to use it, with detailed discussion of what the example does and possible pitfalls. A nice example is the APPEND function, which does not copy the last argument:

The reason most list functions are written functionally is it allows them to return results that share cons cells with their arguments. To take a concrete example, the function APPEND takes any number of list arguments and returns a new list containing the elements of all its arguments. For instance:(append (list 1 2) (list 3 4)) ==> (1 2 3 4)

From a functional point of view, APPEND's job is to return the list (1 2 3 4) without modifying any of the cons cells in the lists (1 2) and (3 4). One obvious way to achieve that goal is to create a completely new list consisting of four new cons cells. However, that's more work than is necessary. Instead, APPEND actually makes only two new cons cells to hold the values 1 and 2, linking them together and pointing the CDR of the second cons cell at the head of the last argument, the list (3 4). It then returns the cons cell containing the 1. None of the original cons cells has been modified, and the result is indeed the list (1 2 3 4). The only wrinkle is that the list returned by APPEND shares some cons cells with the list (3 4). The resulting structure looks like this:

In general, APPEND must copy all but its last argument, but it can always return a result that shares structure with the last argument.

In chapter 9, the first larger practical example is developed, a unit testing framework (like JUnit), which is easy to use and to enhance.

Certain Lisp implementation behaviors can be confusing, such as those for for building pathnames. The pathname concept in Lisp is very abstract, leading to different choices in different implementations. This is no problem if you use only one implementation, but chapter 15 develops a portable pathname library, which works on many implementations. By doing this, it shows you how to write portable Lisp code, using different code for different implementations with reader macros.

After an introduction to the Common Lisp Object System (CLOS) and a few practical FORMAT recipes (the printf for Lisp, but more powerful), chapter 19, "Beyond Exception Handling: Conditions and Restarts", is really useful. The exception handling in Lisp (called "condition system") is more general than other exeption systems: In Lisp you can define restarts where you generate an exception and the exeption handler can call these restarts to continue the program. After reading this chapter, you'll never again want to use the restricted version of Java or C++ exception handling.

Chapters 23 to 31 show real world examples: a spam filter, parsing binary files, an ID3 parser, Web programming with AllegroServe, an MP3 database, a Shoutcast server, an MP3 browser and an HTML generation library with interpreter and compiler. If you ever thought that Lisp is an old language, only used for AI research, these chapters prove you wrong: Especially the binary files parser shows you, how you can extend the language with macros for implementing binary file readers, which looks nearly as clear and compact as the plain text binary file description itself. I'm using some of the ideas for a Macromedia Flash SWF file reader/writer I'm currently writing. Take a look at my Web page for my currently published Lisp projects.

The Web programming chapters demonstrates how to use a dynamic approach for generating web pages. You just start a Web server in your Lisp environment; then you can publish static Web pages or define functions, which are called when the page is requested by a browser. The author demonstrates how to define dynamic pages with formulars in Lisp and Lisp HTML generators.

After reading Practical Common Lisp, you will know most of Common Lisp and how to write real-world programs with it. Some special features, like set-dispatch-macro-character, or using one of the non-standard GUI libraries, are not explained, but it is easy to learn the rest of Common Lisp and to use other Lisp libraries, with the knowledge gained from this book.

eaglebtc writes "A team of neuroscientists at MIT have made tremendous progress in understanding how birds learn to sing: a part of the brain called the basal ganglia is primarily responsible for controlling the learning of movement and the production of speech. This circuitry is also present in humans, and it is the same way that a baby's random babbling eventually becomes the proficient speech of adults. It is hoped that this research can provide further insights into Parkinson's Disease, an inherited genetic condition that causes rapid breakdown of motor control and speech production.

Von Hippel shows the trend already is more advanced than is generally known, and users often freely reveal their innovations for the common good. The social efficiency of a system in which individual innovations are developed by individual users is increased if users somehow diffuse what they have developed to others.....he also notes that the transition to user-centered innovation is hard for some companies to swallow.

An anonymous reader submits "With recent stories about hardware products for the developing world - namely the MIT Media lab's $100 laptop and the Simputer, its interesting to see a software solution to the problems of internet access. Aidworld, a Cambridge (UK) based organisation specialising in ICTs for the developing world have created a free internet service to speed up web browsing in low bandwidth environments: loband. Using server-side compression and by filtering images, scripts and plugins while retaining content and basic formatting, loband reduces bandwidth requirements by between 5 and 50 times. Its making waves in development circles but it also seems to make for a much leaner browsing experience in this world of heavyweight websites. Could this be a much needed stepping stone for users in developing countries? Do high bandwidth consumers find the sites they view could look much cleaner?"

According to the screenshot, it looks like Metafor tries to figure out the components of the software application, defines classes, deduce actions, and generates some function (method) signatures. A PDF document by researchers is available from MIT: "We explore the idea of using descriptions in a natural language as a representation for programs. While we cannot yet convert arbi-trary English to fully specified code, we can use a reasonably expressive subset of English as a visualization tool. Simple descriptions of program objects and their behavior generate scaffolding (underspecified) code fragments, that can be used as feedback for the designer. Roughly speaking, noun phrases can be interpreted as program objects; verbs can be functions, adjectives can be properties. A surprising amount of what we call programmatic semantics can be inferred from linguistic structure. We present a program editor, Metafor, that dynamically converts a user's stories into program code, and in a user study, participants found it useful as a brainstorming tool."

prostoalex writes "The premier issue of Make magazine arrived in a thick envelope in my mailbox a few days ago. The magazine has been previousl publicized on Slashdot. Edited (in chief) by Mark Frauenfelder from BoingBoing and published by John Battelle and O'Reilly, this is an attempt for a quarterly publication for hackers, tinkerers, do-it-yourself type of guys and people interested in technology (not necessarily computers)." Read on for Alex's review; this sounds like the best parts of 1970s-era Popular Mechanics. Make author Published by John Battelle and O'Reilly Media pages 192 publisher www.makezine.com rating 10 reviewer Alex Moskalyuk ISBN 0596009224 summary A quarterly magazine on DIY technology

But enough with the links. On the front page the magazine features 181 pages for DIY technology, promising stories on aerial photography, backyard monorails, XM radio hacks, iPod tricks, DIY magnetic card reader and blogging made simple. Make is roughly half the size of a normal full-page magazine (like PC Mag or InfoWorld) and generally feels like a paperback book more than a magazine. The paper is also not the glossy print you'd see in normal magazines, it says on page 8 that they used New Leaf Paper, made 100% from post-consumer waste. Make generally uses normal-type font, which should be readable by anyone, except for some pages where they switch to really large fonts.

The magazine is broken down into several logical categories. It starts with editors' welcome letters and short features of some DIY projects people have done on their own (this guy's backyard monorail stands out). The Maker pages in this premiere issue contain an interview with Neil Gershenfeld from MIT, an article on heirloom technology, possibility of building an open-source car and an expose of Bay Area Dorkbot group.

The Projects category (starting at p. 49) is where the real fun starts. The projects take up majority of the pages, and it makes sense - looks like the authors put their best into providing excruciating details, pieces of advice and general information, so that anyone can follow their work. The projects are well-illustrated, some contain necessary diagrams and cartoon-like explanations of what needs to be done to assemble the proper devices, the step-by-step pages contain both pictures and text. Each project is sub-divided into several parts - Set up (list of everything needed before you start), Make it (the actual step-by-step instructions and discussion of the projects), Use it (reasons for tinkering with the project in the first place). The setup list is also provided on Make Web site, like here's the list of components for magnetic stripe reader.

The projects for the issue include adding a disposable camera to the kite for aerial photography, a $14 video camera stabilizer, 5-in-1 network cable (the combination of RJ45 and DB9 inputs) and the magnetic stripe reader.

The major projects are followed by the projects consuming less time and efforts. This is mainly for people who would rather spend more money at the spot, buy some cool accessory to complement their electronic device, and do minimal engineering on their own, as far as I understand. The categories include Home Entertainment, Mobile, Cars, Online, Computers and some additional projects that did not fit anywhere above. The table of contents contains the complete list of projects.

It looks like the magazine that is needed in the market. At some point playing with technology became synonymous with running to the nearest mall and getting the latest electronic gadget, and even RadioShack nowadays mostly looks like a flashy storefront for selling cell service plans and new PDAs. Make is the magazine for people who like to look under the hood, who like to work on do-it-yourself projects and who feel great accomplishment when a project is over, even though its practical usability might be questioned. Of course, the amount of projects in the magazine is a bit overwhelming, but my guess is they figure you'll find some extremely interesting and some are just not interesting at all.

Since I grew up in the Soviet Union, Make magazine reminds me of Young Technician (when technician meant someone involved with technology), a Russian must-subscribe boy magazine that would pull the latest science and technology news together, and also dedicate large portion of its pages to readers' projects. Of course, nowadays, in the age of Hack A Day, Lifehacker and numerous HOW-TOs such magazine might not exactly have the exclusive coverage of the DIY projects. Google might turn out more results, but for some of the projects it also looks like the authors were either pioneers or authorities in their field since googling for DIY aerial photography provides just Make article and a bunch of links to it.

Make is a quarterly publication, so $35 subscription fee covers only 4 issues per year. A bit expensive, but if you plan to enrich yourself and spend free time more productively, I think Make has lots of content to entice the reader and keep him busy for 3 months. First impression might not mean a whole lot, but Make was one of few magazines that I enjoyed reading from page 1 to page 192.
