Video Tour the Turn of the Century Electrotherapy Museum (Video) 29

Since he was a teenager, Jeff Behary's been interested in the work of Nikola Tesla, and has been collecting antique electric devices of a particular kind: ones that send electricity through the human body to effect medical benefits, many of which do so with the aid of Tesla coils. Tesla's not the only inventor involved, of course, but his influence overlapped and widely influenced the golden age of electrotherapy. Behary's day job as a machinist means he has the skills to rehabilitate and restore these aging beasts, too, along with a growing family of related devices. He's assembled them now, in West Palm Beach, Florida, into the Turn of the Century Electrotherapy Museum. This is a museum of my favorite kind: home-based and intimate, but with serious depth. Though it's open only by appointment, arranging a visit there is worth it, whether you're otherwise part of the Tesla community or not. Behary knows his collection inside and out, with the kind of deep knowledge it takes to fabricate replacement parts and revamp the internal wiring. The devices themselves are accessible, with original and restored pieces up close and personal — you need to be mindful about which ones are humming and crackling at any given moment. (There's also an archive with books, papers, and other effects relating to Tesla and other electric pioneers, not to mention glowing tubes that predate the modern vacuum tube, and the oldest known surviving Tesla coils, recovered from beneath their maker's Boston mansion. Electrotherapy is the organizing principle, but not the extent of this assembly.) And while Behary isn't fooled by all the therapeutic claims made by some machines' makers about running current through your limbs or around your body, he also doesn't discount them all, either, and points out that some of them really do affect the body as claimed. Yes, he's tried most of the machines himself, though he admits he's never dared taking the juice of his personal Tesla-powered electric chair. View the first video for a tour of part of this astounding collection; the second video is an interview with Jeff Behary.

Book Reviews: Lockpicking Books From Deviant Ollam 123

benrothke writes "It is well known that the password, while the most widespread information security mechanism, is also one of the most insecure. It comes down to the fact that the average person can't create and maintain secure passwords. When it comes to physical locks, the average lock on your home and in your office is equally insecure. How insecure it in? In two fascinating books on the topic, Deviant Ollam writes in Practical Lock Picking, Second Edition: A Physical Penetration Testers Training Guide and Keys to the Kingdom: Impressioning, Privilege Escalation, Bumping, and Other Key-Based Attacks Against Physical Locks that it is really not that difficult. When it comes to information security penetration tests done on the client site, the testers will most often have permission to be inside the facility. On rare occasions, the testers need to find alternative means to gain entrance. Sometimes that means picking the locks." Keep reading to learn if you'll be picking locks soon.

The Foldable Readius Ereader Is Dead 42

Nate the greatest writes "One of the stranger ereader/smartphone hybrid devices ever to grace the pages of a tech blog is now officially never dead. Polymer Vision, creator of the Readius ereader, has been shut down by its parent company. This company launched in 2004 with the goal of bring an ereader with a foldable 5" E-ink screen to market. They shipped an initial production run of about 100 thousand units before going bankrupt in 2009. Wistron bought the company out of receivership and has been paying to develop the screen tech. PV has made a number of prototypes over the past few years, but they never made it out of the lab. The closest we came to ever seeing one was a render of a smartphone design which could expand to the size of a tablet."

Julian Assange: "Online Totalitarianism Is Near, Entire Nations Are Intercepted" 325

dryriver writes "Russia Today's correspondents have visited Julian Assange in the Ecuadorian Embassy in London, where Assange has been holed up for nearly 6 months now. In the 12 minute long interview with RT, Assange has many interesting things to say about privacy, and government data interception in particular. A small excerpt: 'The people who control the interception of the Internet and, to some degree also, physically control the big data warehouses and the international fiber-optic lines. We all think of the Internet as some kind of Platonic Realm where we can throw out ideas and communications and web pages and books and they exist somewhere out there. Actually, they exist on web servers in New York or Nairobi or Beijing, and information comes to us through satellite connections or through fiber-optic cables. So whoever physically controls this controls the realm of our ideas and communications. And whoever is able to sit on those communications channels, can intercept entire nations, and that's the new game in town, as far as state spying is concerned — intercepting entire nations, not individuals. ... So what's happened over the last 10 years is the ever-decreasing cost of intercepting each individual now to the degree where it is cheaper to intercept every individual rather that it is to pick particular people to spy upon.'"

How Does a Single Line of BASIC Make an Intricate Maze? 438

JameskPratt writes "This Slate article talks about a single line of code — 10 PRINT CHR$ (205.5 + RND (1)); : GOTO 10 — and how it manages to create a complicated maze without the use of a loop, variables and without very complicated syntax." Now that amazing snippet of code is the basis of a book, and the book is freely downloadable.

Ask Slashdot: DIY 4G Antenna Design For the Holidays? 135

eldavojohn writes "This holiday season I will return to the land of my childhood. It is flat and desolate with the nearest major city being a three hour car drive away. Although being able to hear the blood pulse through your ears and enjoying the full milky way is nice, I have finally convinced my parents to get "the internet." It's basically a Verizon Jetpack that receives 4G connected to a router. My mom says it works great but she has complained of it cutting in and out. I know where the tower is, this land is so flat and so devoid of light pollution that the tower and all windmills are supernovas on the horizon at night. Usually I use my rooted Galaxy Nexus to read Slashdot, reply to work e-mails, etc. I would like to build an antenna for her 4G device so they can finally enjoy information the way I have. I have access to tons of scrap copper, wood, steel, etc and could probably hit a scrap yard if something else were needed. As a kid, I would build various quad antennas in an attempt to get better radio and TV reception (is the new digital television antenna design any different?) but I have no experience with building 4G antennas. I assume the sizes and lengths would be much different? After shopping around any 4G antenna costs way too much money. So, Slashdot, do you have any resources, suggestions, books, ideas or otherwise about building something to connect to a Jetpack antenna port? I've got a Masters of Science but it's in Computer Science so if you do explain complicated circuits it helps to explain it like I'm five. I've used baluns before in antenna design but after pulling up unidirectional and reflector antenna designs, I realize I might be in a little over my head. Is there an industry standard book on building antennas for any spectrum?"

Ask Slashdot: Will You Shop Local Like President Obama, Or Online? 430

theodp writes "President Obama and his daughters headed to an indie bookstore last Saturday to promote shopping local. The White House did not disclose which books were bought, but author Lauren Oliver tweeted her delight after a White House photo showed her books Delirium and Pandemonium were among the 15 children's books purchased by the Obama family for Christmas gift-giving. While it made for a nice Small Business Saturday photo op, do you suppose the President paid much more for the books at the small indie bookshop than he might have at an online retailer like Amazon, where the hardcopy edition of Pandemonium is $10.15 (44% off the $17.99 list price) and the hardcopy edition of Delirium can be had for $10.47 (42% off the $17.99 list price)? Kindle Editions of the books are also available for $7.99. And with both titles eligible for free Amazon Prime shipping, the President could've saved on gasoline and Secret Service costs, too! So, will you be following the President's lead and shop local this holiday season, or is the siren song of online shopping convenience and savings too hard to resist?"

What "Earth-Shaking" Discovery Has Curiosity Made on Mars? 544

Randym writes "NASA scientists have some exciting new results from one of the rover's instruments. On the one hand, they'd like to tell everybody what they found, but on the other, they have to wait because they want to make sure their results are not just some fluke or error in their instrument. The exciting results are coming from an instrument in the rover called SAM. 'We're getting data from SAM as we sit here and speak, and the data looks really interesting,' says John Grotzinger. He's the principal investigator for the rover mission. SAM (Sample Analysis at Mars) is a suite of instruments onboard NASA's Mars Science Laboratory rover, Curiosity. Grotzinger says they recently put a soil sample in SAM, and the analysis shows something Earth-shaking. 'This data is gonna be one for the history books. It's looking really good,' he says."

Hostess To Close; No More Twinkies 674

RenderSeven writes "In a press release issued today, baker Hostess Brands asked a bankruptcy court for permission to close all of its plants and sell off their assets, immediately laying off 18,500 workers. Citing high labor and rising health care costs, increasing competition and growing consumer awareness of healthy foods, Hostess says it can no longer operate without union concessions. A crippling strike has already shut down operations at all facilities, and while the Teamsters Union has ratified a new contract to keep Hostess in business, the Bakers Union has refused saying they would rather see the company closed than accept pension cuts. The Teamsters union is urging the bakers union to hold a secret ballot on whether to continue striking; citing its financial experts who had access to the company's books, the Teamsters say that Hostess' warning of liquidation is 'not an empty threat or a negotiating tactic' but a certain outcome if workers keep striking. If your late-night programming is fueled by Twinkies, Ding Dongs and Zingers, better stock up now." [Editor's note: A whole bunch of users submitted this news.

Ask Slashdot: High-Tech Ways To Manage a Home Library? 230

DeptofDepartments writes "With Kindles and ebooks on everyone's lips (sc. hands) nowadays, this might come as a surprise to some, but besides being a techie, I have also amassed quite a collection of actual books (mostly hardcover and first editions) in my personal library. I have always been reluctant to lend them out and the collection has grown so large now that it has become difficult to keep track of all of them. This is why I am looking for a modern solution to implement some professional-yet-still-home-sized library management. Ideally, this should include some cool features like RFID tags or NFC for keeping track of the books, finding and checking them out quickly, if I decide to lend one."

Google Engineers Open Source Book Scanner Design 69

c0lo writes "Engineers from Google's Books team have released the design plans for a comparatively reasonably priced (about $1500) book scanner on Google Code. Built using a scanner, a vacuum cleaner and various other components, the Linear Book Scanner was developed by engineers during the '20 percent time' that Google allocates for personal projects. The license is highly permissive, thus it's possible the design and building costs can be improved. Any takers?" Adds reader leighklotz: "The Google Tech Talk Video starts with Jeff Breidenbach of the Google Books team, and moves on to Dany Qumsiyeh showing how simple his design is to build. Could it be that the Google Books team has had enough of destroying the library in order to save it? Or maybe the just want to up-stage the Internet Archive's Scanning Robot. Disclaimer: I worked with Jeff when we were at Xerox (where he did this awesome hack), but this is more awesome because it saves books."

Apple Orders Memory Game Developers To Stop Using 'Memory' In Names 409

An anonymous reader writes with this bit of trademark absurdity from geek.com: "Ravensburger is a German gaming company that specializes in jigsaw puzzles, but has also expanded into other areas such as children's books and games. The company owns the trademark to a board game called 'Memory' and has demanded Apple stop offering apps that have the word 'memory' in their title or as a keyword associated with an app. It may seem ludicrous such a common word can be trademarked, but apparently this is a valid claim as Apple is now serving notices to app developers. The choice an infringing app developer has is to either rename their app or remove it from the App Store."

Book Review: Reverse Deception 43

benrothke writes "Advanced persistent threat (APT) is one of the most common information security terms used today and it is an undeniably real and dangerous menace. Wikipedia notes that APT's usually refer to a group, such as a foreign government, with both the capability and the intent to persistently and effectively target a specific entity. The term is commonly used to refer to cyber threats, in particular that of Internet-enabled espionage using a variety of intelligence gathering techniques to access sensitive information, but applies equally to other threats such as that of traditional espionage or attack. Every organization of size and scope is a target, and many of the world's largest firms and governments have been victims. In Reverse Deception: Organized Cyber Threat Counter-Exploitation, Dr. Max Kilger and his co-authors provide an effective counterintelligence approach in which to deal with APT. The good news is that the authors provide an effective framework. The bad news is that creating an effective defense is not an easy undertaking." Keep reading below for the rest of Ben's review.
