jbeaupre asks: "A corollary to 'Any sufficiently advanced technology is indistinguishable from magic' is that sometimes users have to resort to what I call 'computer voodoo.' You don't know why it works, you barely care how it works, but you find yourself doing the strangest things because it just seems to work. I'm talking about things like: smacking a PC every 5 seconds for an hour to keep it from stalling on a hard drive reformat (with nary a problem after the reformat); or figuring out the only way to get a PC partially fried by lightning to recognize an ethernet card, after booting into Windows, is to start the computer by yanking the card out and shoving it back in (thereby starting the boot processes). What wacky stuff have you done that makes no obvious sense, but just works?"

Editorgirl35 writes "Here's an interesting story on DesignNews.com With last week's announcement that the British government thwarted an alleged terrorist attack planned for flights from the U.K. to the U.S., news that travelers are required to check their laptops as baggage on some flights has raised a new level of panic as they try to figure out the best way to protect their laptops."

pacopico writes "The Register has a mammoth story on a weird art/technology project. An artist has created five life-size wooden figures of Silicon Valley pioneers such as Hewlett and Packard and Intel founder Bob Noyce. These figures are supposed to hitchhike around the country and make their way from the East Coast to Silicon Valley. They're outfitted with GPS tracking systems, and you can watch them move via the web. It's all part of the ZeroOne art and science festival taking place next week in San Jose."

torrensmith writes "Paul Thurrott answers the question that some IT folks are asking: 'Is Windows Vista Ready?' His answer is not only no, but 'No. God, no. Today's Windows Vista builds are a study in frustration, and trust me, I use the darn thing day in and day out, and I've seen what happens when you subject yourself to it wholeheartedly. I think I've mentioned the phrase "I could hear the screams" on the SuperSite before.' He also addresses the more important question, 'When Will Microsoft figure out what's important?' and to Paul, like most IT pros, its not about when the next OS will be released, it is about having the OS work."

Tyler Too writes "With six different versions of Vista due once it ships, figuring out an upgrade path can be confusing. Microsoft has tried to clear things up with a 4x6 matrix laying out your options. 'In short, users of XP Home can do an upgrade install to any of the four Vista versions. However, XP Pro users can only perform upgrade installs to Business or Ultimate.' And if you're not running a 32-bit version Windows XP, there's no upgrade path for you at all."

Carl Bialik from WSJ writes "Steve Perlman is touting technology that he says can create animated digital reproductions of the human body that are as accurate as photographs, the Wall Street Journal reports. From the article: 'Game makers could use the system, called Contour, to create very realistic animated characters in videogames with fully controllable movements and facial expressions. Film makers could use the technology as a kind of digital makeup, changing an actor's looks or words or switch camera angles without costly retakes. The technology can even substitute one actor's face for another's and create exact replicas of long-dead historical figures.'"

Rocky Mann writes "Jesper Johansson, a security guru for Microsoft, is leaving the company to join Amazon.com. Johansson served for some five years as a 'senior security strategist', and is considered one of the world's leading experts on how to protect installations of Windows." From the article: "Johansson is also an advocate for the use of safe-passwords techniques in the enterprise. At the height of the WMF zero-day attacks earlier in 2006, Johansson offered measured advice on the use of unofficial patches and he was constantly on the move, traveling around the world to help customers figure out how to use Microsoft's products securely."

Ground Glass writes "'Can games make you cry?' is a ridiculously simple question to ask about a hideously complex issue. Worse, it's possible that the very question itself muddies the answer. Next Generation's approach is a little more thoughtful; by figuring out what questions each medium tries to answer free of the art issue, it cuts to the heart of what games can do. With the tools made clear, it then theorizes what said tools can do emotionally." From the article: "In film, you can show a character staring at a point before him and then change perspective to show what he was staring at; it is the proximity and timing of the imagery that lends significance to the second shot. In painting, you can play with the two-dimensional space and qualities of the material at hand to create similarly suggestive juxtapositions of imagery, color, symbolism, perspective, lending greater insight into the workings of the medium, the subject at hand, the painter herself, and - ultimately - the viewer and his own perspective on the world around him."

An anonymous reader writes "As part of his 1680-page book Mac OS X Internals: A Systems Approach, Amit Singh of kernelthread.com wrote a very detailed technical history of Apple's operating systems. Since he had to cut down on the history chapter because of the book's already too-large size, most of this chapter didn't make it to the printed book. Singh has made available the history chapter as a free PDF. The file is 140 pages long, and is generously filled with figures and screenshots. It starts with the internals of the original Apple I and goes through a tour of all operating systems Apple dabbled with, including internals of A/UX, Lisa OS, and such. It even covers details of outside influences like the Xerox Alto, STAR System, Smalltalk, and Sketchpad, and closer to home things like Mach, NeXTStep, and OpenStep."

khorner writes "I joined a local XP User Group in May of this year. As the IT Manager of Application Development for a 90+ year old agricultural cooperative, I'm introducing the concepts of agile development and need the support. Right off the bat, we've acquired some review copies of books and I volunteered for the O'Reilly book: Learning SQL on SQL Server 2005. I have been working with various versions of Microsoft SQL Server since 1999, so I figured I could give it a go." Read the rest of Kevin's review. Learning SQL on SQL Server 2005 author Sikha Saha Bagui & Richard Walsh Earp pages 325 publisher O'Reilly rating 4 reviewer Kevin Horner ISBN 0596102151 summary The organization and inconsistencies take away from the value of the book as a whole

Historically, I've found the O'Reilly books to be great references for professional programmers. I began with David Flanagan's Javascript: The Definitive Guide -- I think it was the 3rd edition. I enjoyed them for their reference value as well as business-oriented examples. Learning SQL on SQL Server 2005 does not, in my opinion, follow the mold I have become accustomed to from O'Reilly.

Learning SQL on SQL Server 2005 covers many of the topics necessary to introduce relational databases to the beginner. It is based on the authors' university course curriculum and it is evident with the review questions including with each chapter.

The authors cover important topics at an adequate depth for its target audience; however the organization needs some work. The first six chapters flip-flop across what I consider to be logical boundaries in a discussion on database development: schema versus data. Tools are a platform dependent subject necessary to discuss implementation.

The database provided could use some refactoring to get to a more cohesive and production level design. Not to be nitpicking, but as an example, equivalent domain level attributes for example, student number, are represented across tables as different column names. This is the attention to detail that drives me nuts on the professional level.

Chapter 1 sets the tone by touching multiple concepts and incorporates a smothering of screenshots. Over the first 25 pages (half being images and query result tables) we load the demo database, modify it, select from it, and cover to the Management Studio's syntax color coding and customization. Quite a lot to start off with for a novice, all with the assumption MS SQL 2005 is installed and ready to go.

Chapter 2 jumps into simple data selection of a single table and briefly hits the new MS SQL 2005 concept of synonyms.

Chapter 3 tries to focus on the schema oriented topic of table creation but falls short when jumping over to data topics like INSERT, UPDATE and DELETE. There is good coverage of data types, but we don't cover any design concepts of why we create tables and considerations for doing so. To the authors' defense, they state this is not a book on theory, but I think some level of theory is an important aspect to learn SQL.

Chapter 4 introduces the data selection concept of table joins and to do so, introduces the schema concept of keys.

Chapter 5 provides good coverage on internal functions for strings and dates and sets the foundation for more advanced queries.

Chapter 6 takes the reader through a logical process of developing a complex query. This is a good example process of taking a simple query and developing it further to satisfy a business need. Unfortunately, we experience some more inconsistency when we develop a join query using the WHERE clause - an inefficient and undesirable method the authors' discussed in chapter 4. Again, we jump from data concepts to schemas when we hit views and temp tables.

Chapter 7 through 10 present set operations, sub queries, and aggregate functions in a progressively logical manner. It would have been nice to have this progression prior to Chapter 6 and incorporate the concepts in the query development.

Chapter 11 throws in a thin coat of an introduction to table indexes and constraints: the final jump across topics.

Overall, the book provides an introduction to SQL topics. In my opinion, the organization and inconsistencies take away from the value of the book as a whole. If SQL is your profession (or you want it to be), with a list price of $44.99, Celko's SQL for Smarties is the better investment.

robotrachel writes "According to Technology Review, the $100 laptop intended for children in the developing world will be powered in much the same way that you might start an outboard motor on a boat. The new power system will 'make the laptop much easier to power than it would be with a hand crank, in part, because the users will be able to operate the generator in a variety of ways, including holding the device (the size of two hockey pucks) in one hand and pulling the string with the other, or clamping the generator to a desk, attaching the string to one foot, and using leg power.'" There are plenty of sewing machine treadles in the world, too -- I hope someone can figure out a way to combine them with the new design.

John Dvorak writes on CSS after working on redesigning his weblog, the article ended up being extremely funny. From the write-up:

As we move into the age of Vista, multimedia's domination on the desktop, and Web sites controlled by cascading style sheets running under improved browsers, when will someone wake up and figure out that none of this stuff works at all?!

tappytibbins writes to tell us Baseline is reporting that in a recent look at the 100 largest tech companies they found that there was a striking correlation between the highest paid CEOs and the lowest returns. From the article: "The one-third highest performing companies paid their chief executives an average of $7.12 million--while the bottom third paid their CEOs $9.29 million. The study compared direct compensation, which includes base salary, bonus and value of stock grants. Why the disconnect? Jack Dolmat-Connell, founder and president of the firm, cites the phenomenon of 'chasing the median': Companies benchmark their executive compensation figures on peers instead of looking at factors related to performance."

An anonymous reader writes "Just recently, an update to Windows added the option to password-encrypt a personal folder. The intent was to allow users who share PCs to have a measure of privacy, but C|Net reports the company is now removing that functionality with a patch. IT managers hit the roof when the option was added, complaining of the possibility of lost passwords and inaccessible data." From the article: "'Oh great, have they even thought about the impact this could have on enterprises. I'm already trying to frantically find information on this product so that A) I can block to all our desktops and B) figure out how we then support it when users inevitably lose files. I can see the benefit in this product for home users, but it's a bit of a sloppy release by Microsoft,' Stuart Graham said in a posting on Windows Server-related site MSBlog."

Gamasutra is reporting that sales for the gaming industry were up 25% over last year in June. The results were significantly different than those expected by analysts, primarily driven by high demand for Nintendo's DS Lite handheld console and the videogames based on the Disney/Pixar film 'Cars'. From the article: "Figures from Nintendo claim that combined sales of both Nintendo DS hardware iterations amounted to just under 600,000 in June - a figure with which NPD's estimates of 593,000 agree. PSP sales for the month were put at 221,000, with no information yet available for the Game Boy Advance - which had previously beaten both new portable formats in the U.S."

CurtMonash writes "CNNMoney.com features a skeptical article about the US State Department's plans to soon issue RFID passports (currently being tested on State Department employees). One fear is that they can be hacked for information about you. And even if they can't, carrying around a little transmitter saying 'I'm an American! I'm an American!' isn't a fun and safe thing to do in all parts of the world." From the article: "Basically, you've given everybody a little radio-frequency doodad that silently declares 'Hey, I'm a foreigner,' says author and futurist Bruce Sterling, who lectures on the future of RFID technology. 'If nobody bothers to listen, great. If people figure out they can listen to passport IDs, there will be a lot of strange and inventive ways to exploit that for criminal purposes.'"

Andy Updegrove writes "It's been a week now since Microsoft announced its ODF/Office open source converter project - time enough for 183 on-line stories to be written, as well as hundreds of blog entries (one expects) and untold numbers of appended comments. Lest all that virtual ink fade silently into obscurity, it seems like a good time to look back and try to figure out what it all means. In this entry, I report on a long chat with Microsoft's Director of Standards Affairs Jason Matusow, and match up his responses with the official messaging in the converter press release. The result is a picture of a continuing, if slow and jerky, evolution within Microsoft as those that recognize market demands for more openness debate those that want to follow the old way. This internal divide means that the proponents of change need to point to real market threats in order to justify incremental changes. This adaptation by reaction process leaves Microsoft still lagging the market, but has allowed those that favor a more open approach to gradually turn the battle ship a few degrees at a time."

An anonymous reader writes "Hitwise is reporting that MySpace has reached the top, surpassing Yahoo! Mail as the most visited site on the internet for US users. Seeing a 4300% increase in visits in just two short years, this internet sensation has come quite a long ways. From the article: 'To put MySpace's growth in perspective, if we look back to July 2004 myspace.com represented only .1% of all Internet visits. This time last year myspace.com represented 1.9% of all Internet visits. With the week ending July 8, 2006 market share figure of 4.5% of all the US Internet visits.'"

Casper the Angry Ghost writes "Malware hunters have figured out a way to use the freely available Google SOAP Search API, as well as WDSL, to find dangerous .exe files sitting on thousands of Web servers around the world. Queries can be written to examine the internals of web-accessible binaries, thus allowing the hunters to identify malicious code from across the internet." From the article: "We're finding literally thousands of sites with malicious code executables. From hacker forums, newsgroups to mailing list archives, they're all full of executables that Google is indexing. About 15 percent of the results came back from legitimate Web sites hijacked by malicious hackers and seeded with executables."

Gamasutra reports that, at least in the EU, the Nintendo DS has the portable war pretty much locked up for the time being. 200,000 units of the DS Lite were sold in the ten days after its launch. From the article: "According to Nintendo of Europe, the Nintendo DS has now secured the lead in the handheld market in Europe, with sales of the format exceeding 5 million. No sales figures from Sony are available to compare directly, with only a "shipped" figure of almost 6 million for all territories bar North America and Japan." Interestingly, 136,500 units were sold in the United States in just the first two days after the handheld console's launch.
