Roland Piquepaille writes "If you live near the sea, chances are high that your home is built over sandy soil. And if an earthquake strikes, deep and sandy soils can turn to liquid with disastrous consequences for the buildings built above them. Now, US researchers have found a way to use bacteria to steady buildings against earthquakes by turning these sandy soils into rocks. 'Starting from a sand pile, you turn it back into sandstone,' the chief researcher explained. It is already possible to inject chemicals into the ground to reinforce it, but this technique can have toxic effects on soil and water. In contrast, the use of common bacteria to 'cement' sands has no harmful effects on the environment. So far this method is limited to labs and the researchers are working on scaling their technique. Here are more references and a picture showing how unstable ground can aggravate the consequences of an earthquake."

Career Hot Potato asks: "I've been out of school for little more than a year and I have only good things to say about the job market. So far, there doesn't seem to be any lack of demand for a good .NET developer. I've got to admit, though, I feel a little disloyal at this point. Several great job offers have come my way and I've taken them. My resume is starting to make me look a bit restless and it worries me. Until now I've just chalked it up to 'I'm just settling in,' but now another opportunity has been dropped into my lap. Would I be digging my own grave by taking this job? It'd be my fourth job in 16 months but each offered a promotion and a 30% to 40% raise. I know better than to put a price on job satisfaction but I'm pretty certain I'd be happy there. Is being branded as a 'hot potato' enough to keep you from switching? What's your price on this stigma?"

prostoalex writes "Dr. Dobb's Journal runs a lengthy introduction to Linden Scripting Language, the language behind avatars and their interaction in Second Life: "LSL is a scripting language that runs server-side, on a piece of software called the simulator. The simulator does just what it's name implies — it simulates the virtual world of Second Life. Each simulator runs everything for 16 acres of virtual land — buildings, physics, and of course, scripts. While you manipulate the script text in a form that is somewhat easy to read, the actual code that runs on the simulator is compiled. A compiler is a piece of software that takes the text version of the script and converts it into something that can actually run. In the case of LSL, the compiler exists within the Second Life viewer itself. In the future, it is likely that the compiler will move from the viewer into the Second Life simulators, but where the code is compiled isn't very important. What matters is that the text is converted into a form that can run on the simulators.""

The information includes mirror lists, ways to retrieve the file on P2P networks, checksums for verifying and correcting downloads, operating system, language, and other details. Using Metalinks details the Free Software programs you can use to download them with. There are also clients on Mac and Windows. With a list of multiple ways to download a file, programs can switch to another method if one goes down. Or a file can be downloaded from multiple mirrors at once, usually making the download go much faster. Downloads can be repaired during transfer to guarantee no errors. All this makes things automatic which are usually not possible or at least difficult, and increases efficiency, availability, and reliability over regular download links. OpenOffice.org, openSUSE, and other Linux/BSD distributions use them for large downloads."

DigDuality writes "A new campaign, Showusthecode.com, requests every leader in the Linux world, and companies invested in Linux, to stand up and demand that Steve Ballmer show the world where Linux violates Microsoft's intellectual property. He has been making these claims since the Novell-Microsoft deal. If Microsoft answers this challenge — by May 1st — then Linux developers will be able to modify the code so that it remains 'free' software. If such infringing code doesn't exist, we will have called Microsoft's bluff. And if the campaign garners enough attention and if Steve Ballmer maintains silence, then the community and companies behind Linux can take the silence for the admission that it is."

henrypijames writes "The intense effort by the fair-use community to circumvent AACS (the content protection protocol of HD DVD and Blu-Ray) has produced yet another stunning result: The AACS Device Key of the WinDVD 8 has been found, allowing any movie playable by it to be decrypted. This new discovery by ATARI Vampire of the Doom9 forum is based on the previous research of two other forum members, muslix64 (who found a way to locate the Title Keys of single movies) and arnezami (who extracted the Processing Key of an unspecified software player). AACS certainly seems to be falling apart bit for bit every day now."

Paul asks: "Long ago when digital synthesizers first became commonly available, I recall a reviewer lamenting how he was getting more and more products to test whose software was unfinished and buggy and would require updates and fixes (this, before the internet allowed easy downloads, would have meant a journey to a specialist repair center). The review also commented how this common problem with computer software was spreading (this was before Windows 95 was out), and asked if it was going to become the norm. These days it seems ubiquitous, with PDAs, digital cameras, PVRs and all manner of complex goods needing after-market firmware fixes often simply to make them have the features promised in the adverts, let alone add enhancements. Are we seeing this spread beyond computers and computer-based products; jokes apart, will we be booting our cars up and installing flash updates every week to prevent computer viruses getting into the control systems? Can anyone comment on any recent purchases where they've been badly let down by missing features, or are still waiting for promised updates even whilst a new model is now on the shelves? How can we make the manufacturers take better responsibility? Apart from reading every review possible before making a purchase, what strategy do you have, or propose, for not being caught out?"

IvyLeague Engineer asks: "I'm currently a senior at a top rated public school and I look forward to majoring in Electrical Engineering. I've already been accepted into Carnegie Mellon University, so I don't need to worry about any 'safety' schools. However, I still have my sights set on getting into a school such as MIT or Cal Tech. My grades are high (95.6 on a 100 scale), I have several leadership positions in clubs, however I'm pretty sure that's not enough. What else can I do to improve my chances of being accepted there? I've already been deferred from early action at both institutions and I'm afraid it's too late to do much at this point. I'm sure there are other people like me wondering just what it takes to get admitted to a prestigious college."

gwjenkins asks: "I'm a teacher in charge of IT in a small school. We would like to bust out of the computer lab model but don't want a trolley of laptops wheeled from class to class. I've drooled over wi-fi PDAs but just can't afford a set for class (and the batteries drain too fast). In a classroom, space is at a premium and teachers won't use a technology that takes too long to set up. Most of the time the kids are just researching (Google), or typing (Google Docs), the rest of the time they can go to a lab. I would love to have a desk-based solution. Can you run a wi-fi mini-pc (sitting under the desk) from a 12-volt rechargeable battery (also sitting under the desk) with a 7" LCD (sitting on the desk), that boots from flash card into FireFox? No wires! No setup time! Has anyone done this? How? Alternatively can anyone say why this is silly?"

tfiedler asks: "I manage about 3500 desktop computers and was recently asked by my CIO to begin looking into thin client computing, something like WYSE terminals. I'd like to know, what are some good functional, and more importantly, manageable options to convert existing desktop computers into what would essentially be a Citrix terminal? I was thinking some brand of Linux that starts up an X11 session, starts the Citrix client and connects to our server farm. The user would see a Windows logon, our apps would function as normal and I'd get the benefit of performing a LOT LESS client-side maintenance. Any suggestions?"

It would be hard to argue that World of Warcraft hasn't been a huge success. Not only has it been a financial success in the MMO market, but it has introduced many new people to Massive gaming that might not have otherwise given it a shot. With their first expansion, The Burning Crusade, Blizzard has made huge advances in many areas of the game. Long-standing complaints have been addressed, and the structure of the popular title has been reinforced. The casual players have gotten a large injection of content that is both accessible and enjoyable to someone who doesn't have huge amounts of time to play. At the same time, hardcore players who thirst for new challenges on a daily basis have quite a bit of work ahead of them. This is not to say that The Burning Crusade (BC) doesn't have its pitfalls, but overall I get the feeling that this is closer to what Blizzard's World of Warcraft dream was meant to be. Read on for my opinions of this new round of addiction.

Fennec writes "Amazon.com has launched a beta of a new service called Askville, yet another online answers service, flavored with "Experience Points, Levels, and Quest Coins." These coins will supposedly become useful some day on another Amazon service that's not actually open yet, Questville. If this virtual currency becomes useful, could Askville fill a place between strictly volunteer systems and pay-for-answer services like the now-defunct Google Answers? Or is it destined to fail in the already-saturated online Q&A market?"
