1. Compression would mean less bits transmitted, therefore lower cost.2. It's pretty hard to compress "lol" and "l8r".

Submission + - SPAM: Joomla! A User's Guide
stoolpigeon writes: "It doesn't seem like it has been 3 years since the Mambo dev team split and a new content management system, Joomla! was born. Over the last few years Joomla has grown to be very popular and has very strong developer and user communities. Joomla is extremely flexible and a wide array of extensions exist that allow the system to provide many different capabilities. In "Joomla! A User's Guide", Barrie North provides everything needed to get anyone up and running with a Joomla based site, even if they have little or no experience with creating web sites or applications.
The book is written with language and content squarely aimed at someone new to the tech side of building and running a web site. The language is very simple and even relatively basic terms are explained. As someone with some amount of experience working with software and the web, I didn't find it to be tedious. North does not go on at length, but just gives the information necessary so that someone without the background will be able to keep up. He can also be rather sympathetic to the reader, encouraging them with things that he says can be difficult. That did get a little tiring at times, though I would imagine for his target audience these affirmations could be really assuring. If you are someone who just wants to get a jump on how Joomla works, I wouldn't worry too much about this emphasis on the basic. The book is not overly verbose and so the more basic content does not seem to stretch on forever. North covers a lot of ground in what is a thin book in comparison to much of what seems to dominate the tech book market these days.
While North doesn't wallow in the most basic material and explanations, he never moves on to the really advanced stuff either. If you are interested in coding extensions, or working with the core code, you wont find much here. If you would like a definitive guide with an explanation for every feature and option that exists in Joomla you wont get that either. What North provides is a guide to the most used and most useful information about how to install, set up and run a Joomla based web site. Probably the most advanced material in the book deals with building templates for customizing the look of Joomla. Along with instructions on working with Joomla itself, North also takes some time to also deal with how to generate traffic to a site. For some that chapter may be a bit uncomfortable, though North does a good job of laying out a basic explanation of how things work, as well as practices to avoid. There is a matching appendix on SEO, which is a dirty word in some places. I think that North approaches it with a nice balance between reaching for visibility while avoiding actions that are less than desirable.
The book ends with 3 example sites that the reader can build as they work through the book. These cover a nice range of cases with one being for a school, another for a business and the third is a blog. This gives the reader nice opportunities to play with the software while having guidelines that keep moving things forward and give it all some useful context. A nice companion to this is an appendix with six case studies on existing sites that use Joomla. North interviewed someone from each site and gives an introduction to the site, a screen shot of their front page and then the questions and answers about the site. Together this forms very nice coverage on just what kind of possibilities exist from a real world perspective as opposed to keeping everything purely theoretical.
The book tends to lean towards explaining platform specific items, like installation, from the Windows perspective. I think the assumption is that Linux users will probably already know how to install what they need and are quite likely to already have all the supporting pieces in place. North explains the installation of WampServer for windows users, to get them started with a local install for working through the book. Everything is very hands on and while the screen shots are not in color they are clear and easy to understand. There are also highlighted notes that give the reader reinforcement on what is most necessary to take away from a section.
The support for the book outside of the copy itself is very good. The book comes with 45 days access through Safari. North's site for the book has downloads for the associated files from the book as well as sql dumps from the MySQL databases that correspond to the example sites from the book. Everything necessary to build out the examples in the book, or compare one's work to the authors should problems creep up.
I consider myself to be somewhat technically proficient and at times I did find myself skimming over material that I didn't need. But I did want to use Joomla well and gain that skill quickly and this book was very helpful in that regard. I would think for anyone else who didn't want to waste any time hunting around, this could be a useful guide. Another good use I could see for the book is that it would make an excellent gift to anyone who is not a 'geek' but is using a joomla based site. This could be a client that has a new site you just built for them, or a relative or friend who would like to have a site of their own but seem to call you for support a little too often. I know if I hand off a Joomla site to anyone in the future, unless they are already experience with it, they will be getting a copy of this book.
I've given the book a final rating of 8 on a scale of 10. I do so for two reasons. The first is that Joomla is constantly under development and it is more than likely that in a couple more years or less these instructions will need a major over haul. The second is that while the information on generating traffic was somewhat interesting, I'd have gladly traded it for more information on Joomla itself. Those are relatively minor complaints and from what I've seen, this may be the top Joomla book available right now."

Submission + - SPAM: Warning buoy network saves Right Whales
coondoggie writes: "A new network of smart buoys is adding some much needed protection for endangered Right Whales in Massachusetts Bay's shipping lanes which see some 1,500 ships pass through every year.
The Cornell Lab of Ornithology and Woods Hole Oceanographic Institution deployed the 10-buoy Right Whale Listening Network that can recognize whales' distinctive calls and route the information to a public Web site and a marine warning system, giving ships the chance to avoid deadly collisions. An extraordinary large number of North Atlantic right whales were in the bay earlier this month.
A Boston Globe report said aerial surveys done by the Provincetown Center for Coastal Studies determined that about 79 of the world's remaining 350 right whales — 22% — were feeding in the Stellwagen Bank National Marine Sanctuary and Cape Cod Bay on April 10. As of this writing 61 Right Whale calls had been detected in the past 24 hours according to the research Web Site.

Submission + - Apple Prepares for the Coming iPod Slump
Hugh Pickens writes: "Companies like AOL have stagnated along with the products that made them successful as a mature market and downward pressure on prices led to a nasty death spiral but Saul Hansell writes in the NY Times that Apple has used its amazing six-year run with the iPod to nurture other business lines. Even though the number of iPods sold this quarter grew only 1 percent from the same quarter a year ago, Apple should be able to sustain itself with three business lines that it will help it withstand a collapse in the MP3-player market: a continuing revenue stream from the iPods that have already been sold because of the iTunes Store, product upgrades to the iPhone and iPod Touch that are so different that they may well appeal to a significant number of iPod users, and perhaps most significantly sales of the Macintosh which showed an increase of 51 percent by units and 54 percent by dollars. Apple's computer sales have been growing 2 to 3 times as fast as the overall market and this quarter the company says it grew 3.5 times faster than the PC market overall."
Submission + - Space Shuttle Secrets Stolen for China
Ponca City, We Love You writes: "The Department of Justice has announced the indictment of former Boeing engineer Dongfan Chung on charges of economic espionage in the theft of company trade secrets relating to the Space Shuttle, the C-17 military transport aircraft and the Delta IV rocket. Chung is a native of China and a naturalized U.S. citizen who stole secrets on behalf of China, the indictment says. According to the indictment, Chinese aviation industry representatives began sending Chung 'tasking' letters as early as 1979. Over the years, the letters directed Chung to collect specific technological information, including data related to the Space Shuttle and various military and civilian aircraft. Chung allegedly responded in one letter indicating a desire to contribute to the 'motherland,' the DOJ said. It was not immediately clear how much, if any, damage the alleged espionage did to U.S. national security but DOJ officials said the cases reflect the determination of China's government to penetrate U.S. intelligence and obtain vital national defense secrets. "Today's prosecution demonstrates that foreign spying remains a serious threat in the post-Cold War world,'' said Kenneth L. Wainstein, Assistant Attorney General for National Security"
Submission + - SPAM: Use your cellphone as a 3-D mouse 1
Roland Piquepaille writes: "In recent years, we've started to use our cellphones not only for placing calls or exchanging messages. Now, we take pictures, read our e-mails, listen to music or watch TV. But, according to New Scientist, UK researchers are going further with a prototype software that turns your cellphone into a 3-D mouse. The phone is connected to your computer via Bluetooth. And you control the image on the screen by rotating or moving your phone. As says one of the researchers, "it feels like a much more natural way to interact and exchange data." The technology might first be used in shopping malls to buy movie tickets or to interact with advertising displays. But read more for additional details and a picture showing how a researcher is using his cellphone to control what appears on his screen."

Submission + - Foams with good memory for space applications
Roland Piquepaille writes: "The U.S. National Science Foundation (NSF) has recently reported that two research teams have developed a new porous foam of an alloy that changes shape when exposed to a magnetic field. The NSF states that this new material is able to remember its original shape after it's been deformed by a physical or magnetic force. This polycrystalline nickel-manganese-gallium alloy is potentially cheaper and lighter than other materials currently used in devices ranging from sonar to precision valves. It also could be used to design biomedical pumps without moving parts and even for space applications and automobiles. But read more for additional references and a photograph showing an example of such a magnetic shape-memory foam."
Submission + - Office 2003SP3: Old file formats, now unavailable! 3
time961 writes: "In Service Pack 3 for Office 2003, Microsoft has disabled support for many older file formats, so if you have old Word, Excel, 1-2-3, Quattro, or Corel Draw documents, watch out! They did this because the old formats are "less secure", which actually makes some sense, but only if you got the files from some untrustworthy source.
Naturally, they did this by default, and then documented a mind-bogglingly complex workaround (KB 938810) rather than providing a user interface for adjusting it, or even a set of awkward "Do you really want to do this?" dialog boxes to click through. And, of course, because these are, after all, old file formats, many users will encounter the problem only months or years after the software change, while groping around in dusty and now-inaccessible archives.
One of the better aspects of Office is its extensive compatibility mechanisms for old file formats. At least the support isn't completely gone—it's just really hard to use. Security is important, but there are better ways to fulfill this goal.
This was also covered by the Windows Secrets newsletter, although I can't find a story URL for it."

Submission + - Microsoft deprecating some OOXML functionality (fanaticattack.com)
christian.einfeldt writes: "According to open standards advocate Russell Ossendryver, Microsoft will be deprecating certain functionality in its Microsoft Office Open XML specification. Ossendryver says the move is an attempt to quiet critics of the specification in the run up to the crucial February vote as to whether Microsoft OOXML will be included as a second standard for e-documents, along with the existing ODF ISO standard. ECMA, the Microsoft-led industry standards group formally offering OOXML to ISO, confirms in a 21 December 2007 announcement that issues related to the "leap year bug", VML, compatibility settings such as "AutoSpaceLikeWord95" and others will be "extracted from the main specification and relocated to an independent annex in DIS 29500 for deprecated functionality." Ossendryver is not convinced that deprecation will work, calling the deprecation proposal a 'smoke screen' and a 'bomb disguised as a standard' because 'every application will need to support the deprecated features in order to read files with the deprecated features.' Ossendryver also points out that legacy formatted Microsoft Office documents will still remain non-standard under the new proposal for deprecation."
Submission + - Domains May Disappear After Search 1
Ponca City, We Love You writes: "A perfect domain name pops into your mind, a quick check at your registrar reveals that the domain is available, you put off the registration a few minutes and when you come back to register the domain, it's taken by someone else. How much time has elapsed between the search and the attempted registration — in one case, less than 90 seconds. Daily Domainer has an interesting story alleging that there may be a leak that allows domain tasters to intercept, analyze and register your domain ideas in minutes. "Every time you do a whois search with any service, you run a risk of losing your domain," says one industry insider. ICANN's Security and Stability Advisory Committee (SSAC ) has not been able to find hard evidence of Domain Name Front Running but they have issued an advisory (pdf) for people to come forward with hard evidence it is happening. Here is how domain name research theft crimes can occur and some tips to avoiding being a victim."

Submission + - Egypt to Copyright Pyramids and Sphynx (google.com)
empaler writes: We all know the usual pro-copyright arguments. Most of them hinge on the fact that the individual or company that has a copyright needs an incentive to make something that is copyrightable, and therefore ensure a revenue stream in a period after the copyright has been granted. In a never-surpassed move, Egypt is working on legislation to extend copyright well above 3000 years — they are going to start claiming royalties for using likenesses of the Sphynx and the Pyramids. It is still unclear whether the original intent of the Pyramids included "making sure them bastards pay for a plastic copy in 3000 years" alongside "securing a pathway to the heavens for the God King". Speaking as a Greenlandic national, I want dibs on ice cubes.

He goes on, like many before him, to bemoan the immorality of young people today, saying: "I do know, though, that the TV, movie and record companies' problems have only just begun. Right now, the customers who can't even *see* why file sharing might be wrong are still young. But 10, 20, 30 years from now, that crowd will be *everybody*. What will happen then?""
