"Pathfinders" Take Shape For Galileo, Europe's GPS 105

oliderid sends along a BBC report on progress toward Europe's home-grown GPS system. The Galileo concept will get an initial test via four "pathfinder" satellites that will be the first in the Galileo constellation. Galileo is intended to be complementary with the US GPS system — when all 30 Galileo birds are flying, a receiver with both GS and Galileo capability should enjoy 1-meter positional accuracy, vs. the several meters available through GPS alone, according to the article. There's a video tour of the facility where the pathfinders are being built. "After all the wrangling, the delays, and the furor over cost, Europe's version of GPS is finally starting to take shape. Due for launch in pairs in late 2010 and early 2011, the 'pathfinders' will form a mini-constellation in the sky. They will transmit the navigation signals that demonstrate the European system can become a reality."

Are You a Blue-Collar Or White-Collar Developer? 836

jammag writes "Some developers have gone to four-year universities, where they've also studied subjects like history and sociology, while other coders go to vocational schools and focus purely on writing great software. So why, asks a longtime developer, is there a stigma attached to not having a four-year degree, when 'blue collar' coders might be better trained? Why does the software industry keep emphasizing this difference — and generally giving better pay to four-year grads? Isn't being a developer about real skill level, not the piece of paper on the wall?"

The "Hail Mary Cloud" Is Growing 102

badger.foo writes "The Australian rickrolling of jailbroken iPhones only goes to prove that bad passwords are bad for you, Peter Hansteen points out, as he reports on the further exploits of the password-guessing Hail Mary Cloud (which we've discussed in the past). The article contains log data that could indicate that the cloud of distributed, password-guessing hosts is growing. 'With 1767 hosts in the current sample it is likely that we have a cloud of at least several thousand, and most likely no single guessing host in the cloud ever gets around to contacting every host in the target list. The busier your SSH deamon is with normal traffic, the harder it will be to detect the footprint of Hail Mary activity, and likely a lot of this goes undetected.'"

The Space Garbage Scow, ala Cringely 221

An anonymous reader writes "Robert X. Cringely once again educates and amuses with his take on how we could clean up the garbage that's in orbit around Earth. I cannot vouch for his math, but it makes sense to me. Quoting: 'We’d start in a high orbit, above the space junk, because we could trade that altitude for speed as needed, simply by flying lower, trading potential energy for kinetic. Dragging the net behind a little unmanned spacecraft, my idea would be to go past each piece of junk in such a way that it not only lodges permanently in the net, but that doing so adds kinetic energy (hitting at shallow angles to essentially tack like a sailboat off the debris). But wait, there’s more! You not only have to try to get energy from each encounter, it helps if — like in a game of billiards or pool — each encounter results in an effective ricochet sending the net in the proper trajectory for its next encounter. Rinse and repeat 18,000 times.'"

NIF Aims For the Ultimate Green Energy Source 234

theodp writes "Edward Moses and his team of 500 scientists and engineers at Lawrence Livermore's National Ignition Facility are betting $3.5B in taxpayer money on a tiny pellet they hope could produce an endless supply of safe, clean energy. By the fall of 2010, the team aims to start blasting capsules containing deuterium-tritium fuel with 1.4 megajoules of laser power, a first step towards the holy grail of controlled nuclear fusion. Not all are convinced that Moses will lead us to the promised land. 'They're snake-oil salesmen,' says Thomas Cochran, a scientist with the Natural Resources Defense Council. Moses, for his part, seems unfazed by the skepticism, saying he's confident that his team will succeed."

Submission + - SPAM: X Power Tools

stoolpigeon writes: "The X Window System has been around for over twenty years and is the display system for an incredibly wide range of operating systems. With the number of Linux users growing, there are more people working with X than ever before. Most modern desktop environments provide user friendly interfaces that make modifying X rather simple. There is not so much need to dig into config files and settings as in the past but for those environments without such tools or for the user who loves to dig deep into their environment this book can be a simple way to understanding how X works and how to tweak it in any number of ways. If you want things that 'just work' and have no interest in digging around below the surface this book is not for you. On the other hand, if you think the best thing to do with a shiny new tool is to take it apart, well "X Power Tools" by Chris Tyler may be just for you.

The author, Chris Tyler, is a professor at Seneca College in Toronto as well as a programmer and Linux user. His first book published by O'Reilly was "Fedora Linux: A Complete Guide to Red Hat's Community Distribution", published in 2006. He cites the growth in X users, combined with active development and the lack of existing books that address X as the motivation for writing "X Power Tools."

X is the windowing system on a wide range of Unix and Unix like systems. Chris is obviously most familiar with Linux and so the material is heavily Linux oriented. This is most apparent when the book deals with Session Managers, Desktop Environments and Window Managers. The material focuses on Gnome, KDE and Xfce and their associated components in regards to X. For the Linux user this could be a valuable resource.

When I've had issues in working with X locally and over the network, I've found that while what I need is available on the web, getting just what I need can be very labor intensive at times. Usually just what I want is spread across tutorials, on-line man pages and forum posts. Sorting out what applies to my situation can be especially difficult when I'm not even sure just how things work for my setup. Chris makes this kind of guessing unnecessary and provides the locations and function of key files. He also spells out how the most important files and tools can be best used.

For the sysadmin on another platform, these Linux specific sections are not going to be much help. Most of the book though, deals with X itself. I've already loaned my copy to one of our AIX admins more than once and I think he plans on picking up a copy of his own.

When Gnome and KDE provide an interface for modifying or customizing X functionality, the book gives at least the name of the program and sometimes screen shots and explanations of how the tool works. This is always after an illustration of how to get the job done with the tools that are a part of X itself. From fonts to keyboard layouts, multi-display to kiosks, everything required is laid out in straight forward terms.

For me, as a Fedora user myself, this means that having read this book I approach my work environment with a new level of confidence. Behaviors that used to puzzle me, now make complete sense. Quirks that bothered me, no longer need to be tolerated as I know have the tools to get things working just the way I want, rather than using defaults.

The book has just come out, so it was being written before the release of KDE 4. I've looked through the documentation and I don't think any of the changes to programs like KDM or KWin make the information in the book out of date. In fact, according to the KWin release notes, when discussing KWins new compositing support, "...manual configuration of X may be required for proper results..." So if you are a KDE user that likes to live on the edge, this book may come in handy.

O'Reilly says that their "Power Tool" books are comprised of a series of stand-alone articles that are cross-referenced to one another. To be honest, it didn't feel much different from reading any other tech book. Topics flowed naturally and the articles are analogous to sections that divide up chapters in other books. One nice navigation feature is that page numbers are on the bottom of the pages while chapter and article numbers are at the top corner in a decimal notations. For example at the top of page 58 there is a grey square containing the number 3.13 which means that it is the 13th article in chapter 3.

The book has a thorough index. It also comes with 45 days free access to an electronic version through O'Reilly Safari.

For me the only real weakness of the book is that I would like to have seen more information on working with X on Unix. When reference is made to specific implementation of X it is almost always in regards to Linux. I wouldn't want to lose that, but I think a mixed environment of Unix, Linux and Windows is more the rule than the exception today. It would be more work to include other operating systems, but it would have also made the book much more valuable.

All tech books face the danger of becoming quickly useless as progress marches forward. X is actively being developed, but at the same time, looking back on its history I think this book will be useful for sysadmin and user for some time to come."

Submission + - SPAM: A crystal as beautiful as a diamond

Roland Piquepaille writes: "Why are diamonds so shiny and beautiful? A Japanese mathematician says it's because of their unique crystal structure and two key properties, called 'maximal symmetry' and 'strong isotropic property.' According to the American Mathematical Society (AMS), he found that out of all the crystals that are possible to construct mathematically, just one shares these two properties with the diamond. So far, his K4 crystal exists only as a mathematical object. And nobody knows if it exists — or if it can be synthesized. So will we say one day "A K4 Crystal Is Forever"? Read more for additional references and a picture of the beautiful K4 crystal."

Copyright Cutback Proposed As RIAA Solution 709

An anonymous reader writes "InfoWeek blogger Alex Wolfe proposes a novel solution to the ongoing spate of RIAA lawsuits over alleged music copying. He suggests legislation which cuts back corporate copyrights from 120 years to 5 years. 'We should do what we do to children who misbehave,' he writes. 'Take away their privileges.' Wolfe says this is regardless of the misunderstanding surrounding the latest case, which apparently isn't about ripping CDs to one's own computer. As to those who say copyrights are a right: "That's simply a misunderstanding of their purpose. Copyrights, like patents, weren't implemented to protect their owners in perpetuity. They are part of a dance which attempts to balance off societal benefits against incentives for writers and inventors. You want to incentivize people to push the state of the creative and technical arts, but you don't want give those folks such overbearing protections that future advances by other innovators are stifled." What do you think; is it time to cut off the record industry?"

Lucas123 writes: "More than half of all Americans visited a library this past year and, of those, most were from Generation Y, the tech-loving young adults aged 18-30 years, according to a recent survey . The reason most cited for visiting their local public archive? Not books. Most were seeking gaming software programs, characters in the Second Life virtual world and online help with homework. "These findings turn our thinking about libraries upside down," said Leigh Estabrook, a professor emerita at the University of Illinois and co-author of a report on the survey results.""

Submission + - NYT Article About One of the Original Phreaks 1

tmalone writes: The New York Times is running an end of year piece about the most interesting people who have died this year. One of their picks is Joybubbles, also known as Josef Engressia, or "Whistler". He was born blind and discovered at the age of 7 that he could whistle 2600 hertz into a phone to make free long distance calls. He was one of the original phone phreaks, got arrested for phone fraud, and was even employed by the phone company. The article deals more with his personal life (he was abused at a home for the blind) than with his technical exploits, but is a very interesting story.

Submission + - The Rising Barcode Security Threat (heise-security.co.uk)

eldavojohn writes: "As more and more businesses become dependent on barcodes, people are pointing out common problems involving the security of one or two dimensional barcode software. You might scoff at this as a highly unlikely hacking platform but from the article, "FX tested the access system of an automatically operated DVD hire shop near his home. This actually demanded a biometric check as well, but he simply refused it. There remained a membership card with barcode, membership number and PIN. After studying the significance of the bar sequences and the linear digit combinations underneath, FX managed to obtain DVDs that other clients had already paid for, but had not yet taken away. Automated attacks on systems were also possible, he claimed. But you had to remember not to use your own membership number." The article also points out that boarding passes work on this basis — with something like GNU Barcode software and a template of printed out tickets, one might be able to take some nice vacations."

theodp writes: "Ready for one-automobile-per-child (OAPC)? India's giant Tata Group is on the verge of launching the world's cheapest car. The People's Car, slated to be unveiled January 10th at a New Delhi auto show, will carry a sticker price of 100,000 rupees ($2,500), which some analysts say could revolutionize automobile costs worldwide. The cheap car, a pet project of Cornell-trained architect Ratan Tata that he helped design, is aimed at improving driving safety by getting India's masses off their motorbikes and into cars."
