DullTrev asks: "The hierarchical database model existed before the far more familiar relational model. Hierarchical databases were blown away by relational versions because it was difficult to model a many-to-many relationship - the very basis of the hierarchical model is that each child element has only one parent element. However, we now live in a web world that demands quick access to a variety of data on a variety of platforms. XML is being used to facilitate this, and XML has, of course, a hierarchical structure." Do you think a hierarchical database would really be a better answer for storing XML data over the existing relational counterparts?

"There have been some pushes to create pure XML databases (info on XML in connection to databases is here and info on XML database products is here) with claims that as they support XML natively, they can offer many advantages over relation databases.

Some of these claims include speed, better handling of audio, graphic and other digital files, easier administration, and handling of unexpected elements. Software AG, a German firm, produce and sell a suite of XML products, including Tamino, a native XML database. They have lots of information on why they think there database is great, not surprisingly, but no benchmarks. So, do the Slashdot community think that with XML the time has come for hierarchical databases? Or is it better simply to use a relational database that can output in XML, or script your way to achieve the same goal?"

Cutriss writes: "The ICANN seems to be thinking about giving in to public demands. According to this article on Wired.com mentions that ICANN is considering allowing domain owners to elect their board of directors. It's a step in the right direction. I wonder if domain owners could collaborate and cast a collective vote of no confidence, absolving ICANN of its responsibilities..." I wouldn't call it a step in the right direction since each revision to ICANN's Board involves less individual representation and more corporate representatives. There's another story with some quotes from Karl Auerbach. The At-Large study that we talked about earlier has now been released in its final form. If you don't like the way ICANN is going, please consider attending their meetings. Next one is in Los Angeles next week.

Cdgod asks: "I am working on a thesis regarding DRM (Digital Rights Management). I would like to get it published and instead of having the regular recycled net material, I would like to hear opinions and thoughts on how it should and could work. Think 20 years in the future, how can you see your world with DRM in place? Will it cost you a few pennies every time you look for the time on your watch? Are you limited to only coping that CD 3 times before it is locked forever? Can you think of uses where DRM will actually give the user more rights? Try to think outside the current models in place, such as video on demand, purchasing music online, and DRM e-books. And yes, I will be arguing that the current laws are not taking the user's point of view, but of the large media companies." My personal thoughts on Digital Rights Management (copy protection, for laymen) is that as long as it interferes with the user's use of the material, it's not worthwhile. Most of the current solutions which have been proposed seem more like draconian measures that will be forced down our throats...whether we like it or not.

Yokaze writes: "The Wall Street Journal reports about a leaked European Comission document, that suggests that the EU may fine MS for anti-competitive behaviour. The fine can be up to 10% of the annual revenue, or $2.5 billion and may include the demand to remove certain programs from Windows. The report harshly criticized MS way of taking influence in the case, even speaking of trying to mislead the observers. Regarding the report of the WSJ, European Competition Commissioner Mario Monti said, that the case is still at a preliminary stage, since MS still has the right to defend itself at a hearing. Or in his own words: 'To speak of a fine when Microsoft has not yet disputed the Commission's preliminary findings both in fact and law -- as it it's right -- is premature.' Since the original is for subscribers only, take a look at Yahoo or the more detailed report from BBC News. Lastly with some different details a report from Heise in German."

Lurks asks: "My company, Codeplay, is set up to develop new and innovative compiler technology for the games industry. Our C compiler, VectorC, is a cutting edge vectorizing compiler aimed at games and multimedia applications that demand high performance generally through hand-optimized assembly. I'm writing to ask the burning question on our minds, is it worth porting VectorC to Linux? In fact, we're already targeting Linux as part of the PlayStation 2 version albeit not generating x86 code of course. A Linux port would see us converge this work with our Win32 compiler and such an undertaking would certainly be popular with our Linux loving techies! One caveat worth mentioning now is that the current version of VectorC is plain C only. 2.0 with full C++ compatibility is due early next year."

"Of course, commercial realities will rear their ugly head and we must consider that Linux isn't perhaps an obvious choice for a compiler aimed at games and multimedia applications. Given the certain degree of hostility towards commercial closed-source products of this nature, perhaps the idea should be consigned to the pet-project back burner for the future rather than rolled out as a commercial product?"

cdrudge writes: "According to this article on CNN, AMD will be closing 2 plants in Austin, TX and also their operations in Penang, Malaysia due to slack demand. 2300 jobs will be cut in the process. The same article mentions Gateway dropping it's 'Select' line of computers. Their 'Select' line of computers were Gateway's only AMD-based systems. A Gateway spokesperson said 'We're consolidating all of our offering behind Intel, which was the biggest part of our mix already.'"

An Anonymous Coward writes: "An unoffical announcement on the empeg BBS (home of their finatical user base) is that SONICblue's current aftermarket car linux product, the Rio Car (formerly the empeg Car Player) has been EOL'd. While it remains the most advanced car player available, there was not enough demand to keep that group profitable. It will continue to be sold through their e-stores (Non-USA and USA) until inventory is exhausted. This was/is the ultimate in car stereo for MP3 playback. Disappointing."

Anonymous Coward writes "LinuxDevices.com reports that the Free Software Foundation has reached an agreement with Victor Yodaiken which resolves what FSF considered to be a violation of GPL by the Open RTLinux Patent License. Details are not yet available, but it sounds like the clause in the license which required users of RTLinux to keep records and provide them to FSMLabs on demand was the principal source of the violation, and that the requirement is being dropped from an updated version of the RTLinux license that will be published in the next day or two. All in all, it seems like the FSF has successfuly enforced the GPL even though it was neither an owner nor co-owner of the software (i.e. the linux kernel) whose license terms were being violated. It's interesting to see this practical example of FSF in action, and bodes well for the future of GPL -- at least in a small way."

crimoid points to ZDNet coverage of the FSF's criticism of RTLinux's licensing terms, written before such a resolution was clear. Sourceforge on Thursday quoted RTLinux CEO Victor Yodaiken, CEO as saying that his company is happy to change "minor problems" with the RTLinux license, and that discussions are still going on with the FSF about those changes.

NaughtyusMaximus points us to this message at Anandtech about Via reacting to Intel's patent-infringement suit by turning around and suing Intel -- for patent infringement -- in Taiwan and the U.S.. Via is also countersuing Intel in England.

John Macdonald asks: "An ADSL connection uses the asymmetric (that's the A in ADSL) bandwidth to provide much larger download than upload capacity. That's great for many situations, where people browse and collect, importing data far more than they export to the world at large. But there are some sites that could use the asymmetry more effectively the other way - with a large upload capacity and small download. This would work well for ftp and web servers, for example. So, why don't telcos provide this inverse capability? Is the hardware more expensive to run the other way? Is there just too little demand? Has nobody thought of it before? I'd guess that there is small enough demand that they prefer to only offer a symmetric, higher-speed, but also higher-priced, connection for such sites."

An unnamed reader contributes this link: "PC Formathave story about Microsoft's follow up to the XBox. Rumor is it's a home entertainment centre called HomeStation. It'll offer video and TV on demand, and act as an internet gateway for internet appliances. Profiling is mentioned. The story makes an interesting point about how the XBox's true purpose is to pave the way for Microsoft as a home entertainment brand."

cconnell writes: "Most software design is lousy. Most software is so bad, in fact, that if it were a bridge, no one in his or her right mind would walk across it. If it were a house, we would be afraid to enter. The only reason we (software engineers) get away with this scam is the general public cannot see inside of software systems. If software design were as visible as a bridge or house, we would be hiding our heads in shame. This article is a challenge to engineers, managers, executives and software users (which is everyone) to raise our standards about software. We should expect the same level of quality and performance in software we demand in physical construction. Instead of trying to create software that works in a minimal sense, we should be creating software that has internal beauty." We had a good discussion on a related topic half a year ago.

bubblegoose writes "In Washington state Qwest customers are asking for a refund due to losses of service during the Code Red thing. Qwest is refusing to give the refunds. Excite has a story about it here." I tend to think this is just complaining bull crap. My net connection when down too, and I don't run around demanding $5 back. I'd be more upset if I was a business and my server rooted by this. The irony is that this will probably end up just pushing subscription software.

jsse writes "In a news conference IBM's senior vice president Steve Mills said 'the company will gladly drop its version of Unix from servers and replace it with Linux if the software matures so that it can handle the most demanding tasks.' Now the Giant, along with many other companies, jump to Linux bandwagon. The question is wether this bandwagon is capable of carrying a Giant that huge. Or the question is: can Linux beats AIX?"

Trapped In Windows Hell asks: "I was just at the local game store looking for a new game, and I noticed the absolute lack of ANYTHING other than DirectX games. Where has OpenGL gone, and what does this mean for games on GNU/Linux? If DirectX is so hard to program in, so clunky to use, and limits the game to being sold on only one OS, WHY do so many programmers use it? It seems logical (to me, at least) that programming as portably as possible, as simply as possible, and using standards where possible, leaves a lot more sales options open for the future... and DirectX seems to close all options *but one*." OpenGL use in Windows gaming has decreased dramatically in favor of the use of DirectX which is improving with each release. Will OpenGL continue to mature on the Windows platform (which arguably is the platform that drives most of the mainstream demand for graphics) or will it continue to stagnate as game and driver developers concentrate on the offerings from Microsoft?

aclute sent in a bit saying that Dell is dropping Linux from desktops and laptops. They cite low demand, and they plan to continue shipping Linux on the server. I've sworn off Dell PCs since their finance dept. tried to screw me over on the laptop I leased for a few years in college (No, we never got that laptop back. Nor can we explain why you have signed confirmation that it was delivered. You owe us a year's worth of late fees). Frankly there are much less expensive places to get a Linux laptop, but those suckers with the 1600x1200 screens and the GeForce 2 video card are still super pimp.

A dog'n'pony show is that delightful moment where some $1000 suits and the investors wearing them politely demand to be shown why they've paid you a salary for the last three months without hearing anything back except "we're all working hard here" and "stop bothering us and it'll get done faster." You pray the software works as well now as it did at 5AM when you finally killed the last display bug and headed home for a quick shower. Just two words of advice: don't cheat. Like VisuaLABS did with its "tiled LCD screens," or the Pentagon with its "missile defense test," you'll get caught. ...or will you? Tell us your best demo war stories.

Thanks to coli for passing along last Thursday's press release from VisuaLABS. This is a company that has been telling investors that they have what they call "GroutFree(tm)" technology, which joins multiple LCD screens invisibly into one, large, flat screen.

On July 3rd, investors were wowed by the demo of the company's "42 inch diagonal flat screen display" prototype. Sheldon Zelitt, VisuaLABS' Chairman and Chief Scientist, said, "It was our great pleasure to share an early look at that technology with our loyal shareholders at the Shareholders' Meeting."

And on July 26th, we got another press release -- this one titled "VisuaLABS Announces That Its Primary Technologies Are Not As Represented And Dismisses Sheldon Zelitt." It turns out that "the large screen GroutFree prototype demonstrated at the Annual Meeting was, in fact, a standard 42 inch plasma television purchased by Sheldon Zelitt ... at a local Calgary consumer electronics retailer ... The Committee believes that no working prototype of a device incorporating the GroutFree technology exists."

While all this was going on, the Pentagon was busy launching two missiles and making them smack into each other. This is the missile defense justification, the one scientists say can't be done, the umbrella that will protect the U.S. and its allies from all those Third World dictators who just have to deliver their nuclear warheads the hard way.

The big test came on July 14, when a target missile (avoiding mishaps) was launched and successfully blown to pieces by its interceptor. Bush was "pleased." CNN showed us the debris radar. And Michael Kelly of the Washington Post stuck it to the "liberal critics," pointing out that "The 'Smart People' Were Wrong." As he wrote:

"In the blink of a video screen going blinding white on July 14, it became impossible to offhandedly disdain a missile defense system as 'weapons that don't work.' It does work."

Yep! So phase one of our missile defense plan is complete. Now we go on to phase two, which is to convince all our enemies to install GPS transmitters in all their missiles.

Oh, you didn't know the test missile had a GPS transmitter on board? Well, you do now.

My favorite part is that the test missile actually launched a Mylar balloon as "chaff" to try to fool the "kill vehicle." Luckily, the balloon didn't have GPS.

So what's your favorite dog'n'pony story? Ever had a demo fail in some especially embarrassing way? Ever cheated? Ever get caught? C'mon, you can tell us...

Update: 08/01 08:00 PM by J : I'm seeing a lot of discussion of the relevance of the GPS. Here's Defense Week which claims the "prototype interceptor was able to find a target warhead partly because the target signaled its location to the interceptor for much of the flight, and the transmissions formed the basis of the targeting orders."

And thanks as always to Slashdot readers for posting more information. monopole points out this link, or take your pick, this one -- they're plans from last year, but still interesting:

SR. DEFENSE OFFICIAL: And we take the GPS data, and we fuzz it up quite honestly, because GPS is a lot more accurate than radars. Okay? [...]

Q: Well, actually, would you then use the degraded GPS, or would you just the regular GPS that you use as a fallback -- (inaudible word)?

SR. DEFENSE OFFICIAL: (Inaudible.)

STAFF: Use the regular GPS.

SR. DEFENSE OFFICIAL: Regular GPS.
