An anonymous reader writes "Print-on-demand publisher Lulu recently announced that they're offering 'eBooks.' Since they've always offered downloadable books as PDFs, that takes some decoding to figure out what part is new: it turns out that it means now they're handling more formats, they've significantly increased the share they take out of the purchase price ... and for an additional fee, they now offer DRM. I have a few items published through Lulu myself; nothing forces me to buy the DRM, but I'm considering taking my business elsewhere on principle. This isn't what I expected from the people who, when I first signed up with them, were solidly endorsing Creative Commons."

Techdirt has pointed out yet another cable exec that just doesn't quite get it. Comcast's COO, Steve Burke, recently urged the TV industry to find ways to "get consumers to change" rather than figure out better methods to cater to demand. "'An entire generation is growing up, if we don't figure out how to change that behavior so it respects copyright and subscription revenue on the part of distributors, we're going to wake up and see cord cutting.' How many consumers, in any market, are focused on 'respecting' vendors' revenue streams? How, exactly, does he propose to effect this sea change? And why not just develop products that consumers will willingly pay for, rather than trying to change consumer behavior in such a fundamental way?"

Dr_Barnowl writes "In an occurrence first postulated in sci-fi and later lampooned by stick figures, it seems that a blogger has actually been responsible for the mass resignation of elected officials — a British town council — largely by calling them 'jack***es' and Nazis. What's next? The deposition of a president with 'your mom' smacktalk?"

Pickens writes "Science Daily News reports that human missions to Mars and all other long-term space flights might be compromised by disease, first because space travel appears to weaken astronauts' immune systems; and second, because it increases the virulence and growth of microbes. 'When people think of space travel, often the vast distances are what come to mind first,' says Jean-Pol Frippiat from Nancy-University in France, 'but even after we figure out a way to cover these distances in a reasonable amount of time, we still need to figure out how astronauts are going to overcome disease and sickness.' Frippiat says studies show that immune systems of both people and animals in space flight conditions are significantly weaker than their grounded counterparts and that common pathogens such as Salmonella, E. coli and Staphylococcus reproduce more rapidly in space flight conditions, leading to increased risk of contamination, colonization and serious infection."

AdmiralXyz writes "I'm a university student, and I like to take notes on my (non-tablet) computer whenever possible, so it's easier to sort, categorize, and search through them later. Trouble is, I'm going into higher and higher math classes, and typing "f_X(x) = integral(-infinity, infinity, f(x,y) dy)" just isn't cutting it anymore: I need a way to get real-looking equations into my notes. I'm not particular about the details, the only requirement is that I need to keep up with the lecture, so it has to be fast, fast, fast. Straight LaTeX is way too slow, and Microsoft's Equation Editor isn't even worth mentioning. The platform is not a concern (I'm on a MacBook Pro and can run either Windows or Ubuntu in a virtual box if need be), but the less of a hit to battery life, the better. I've looked at several dedicated equation editing programs, but none of them, or their reviews, make any mention of speed. I've even thought about investing in a low-end Wacom tablet (does anyone know if there are ultra-cheap graphics tablets designed for non-artists?), but I figured I'd see if anyone at Slashdot has a better solution."

shrik writes "Slate has a look at the efforts of Emily Owens, in 2005 a Ph.D student in economics at the University of Maryland, who 'came across thousands of inconsistencies and errors in the sentencing recommendations provided to judges' by the Maryland State Commission on Criminal Sentencing Policy. Quoting: 'The sentencing guidelines for judges were based on a work-sheet [PDF] that "graded the severity of a convict's crime and his risk to society", ostensibly to make the rulings meted out more objective in nature. But on carefully studying her data, Owens noticed something wasn't adding up — the system seemed to be producing 1 error in every ten trials. She also realized that this "recommendation system" actually mattered: crimes and criminals analyzed to be quite similar were resulting in systematically different punishments correlated with the work-sheet.' The source of these discrepancies was ultimately found to be a simple, but very significant, PEBKAC: 'More than 90 percent of errors resulted from the person completing the work sheet [usually the DA, but signed off by the defense attorney] entering the figure from a cell next to the correct one. ... The remaining errors came mostly from incorrect choice of criminal statute in calculating the offense score and from a handful of math errors (in operations that were literally as simple as adding two plus two).' Timo Elliott's BI Questions Blog lists the morals of the story."

An editorial at GameSetWatch examines whether game publishers really deserve all the flak they get from gamers and developers alike. While some questionable decisions can certainly be laid at their feet, they're also responsible for making a lot of good game projects happen. Quoting: "The trouble comes when the money and the creativity appear to be at odds. ... Developers and publishers often have a curious relationship. The best analogy I can think of is that of parent and child. The publisher or parent thinks it knows best, because it's been there before (shipped more games), and because 'it's my money, so you'll live by my rules.' The developer — or child — is rebellious, and thinks it has all the answers. In many ways, it does know more than the parent, and is closer to what's innovative, but maybe hasn't figured out how to hone that energy yet."

ericatcw writes "Taking a page out of McDonalds 'billions and billions served,' Microsoft says it reaps $1.3 billion a year from more than 100 million users of its SharePoint collab app. But some suggest that the figures are consciously inflated by Microsoft sales tactics in order to boost the appearance of momentum for the platform, reports Computerworld. A recent survey suggests that less than a fourth of users licensed for SharePoint actually use it. SharePoint particularly lags as a platform for Web sites, according to the same survey, a situation Microsoft hopes to fix with the upcoming SharePoint 2010."

An anonymous reader writes "Ian Clarke, creator of Freenet, has been working on a new open source project called Swarm. The concept is to allow a computer program to be distributed across multiple computers in a manner almost completely transparent to the programmer. The system observes the program executing and figures out how the workload should be distributed for maximum efficiency. Swarm is implemented in Scala. Its at an early-prototype stage, and Ian has created a good 36 minute video explaining the concept and the current implementation."

Reader oranghutan brings us another in Computerworld's series of interviews with icons of the programming world, this one with Brian Kernighan, who helped popularize C with his book (co-written with the creator Dennis Ritchie) The C Programming Language, and contributed to the development of AWK and AMPL. In the past we've chewed over a few other interviews in this series, including those with Martin Odersky on Scala and Larry Wall on perl. "In this interview, Brian Kernighan shares his tips for up-and-coming programmers and his thoughts on Ruby, Perl, and Java. He also discusses whether the classic book The Practice of Programming, co-written with Rob Pike, needs an update. He highlights Bill and Melinda Gates as two people doing great things for the world enabled through computer science. Some quotes: 'A typical programmer today spends a lot of time just trying to figure out what methods to call from some giant package and probably needs some kind of IDE like Eclipse or XCode to fill in the gaps. There are more languages in regular use and programs are often distributed combinations of multiple languages. All of these facts complicate life, though it's possible to build quite amazing systems quickly when everything goes right.' 'Every language teaches you something, so learning a language is never wasted, especially if it's different in more than just syntactic trivia.'"

We recently discussed the release of the PSP Go, which drew criticism for many design choices that were of dubious value to consumers. Now, Phaethon360 sends in a story about why Sony felt the need to improve upon the old PSP. "As a format, the UMD was holding the entire platform back. Few people (if anyone) bought into the UMD movie hype Sony attempted to thrust back in 2005. Very soon after that, people realized they could rip their DVDs to a memory stick with the same quality. It's ironic how, as the price of Sony Memory Stick Pro Duo dropped and size increased, PSP UMD sales decreased along with it. It doesn't take too many Howard Stringers to figure out what the problem was." Indeed, Sony was complaining of rampant PSP piracy for quite some time. They cited "legal and technical issues" for not supporting the transfer of UMD games onto the PSP Go; undoubtedly they couldn't find a way to keep pirated games from being copied.

Last night I finally scraped together the two hours to watch the premiere of Stargate Universe. Since the last two series really ran their course and deserved to end, I was skeptical. At first blush it appears that the show is just Atlantis + Voyager, shot in the documentary style that practically every sci-fi show since Firefly uses. But I enjoyed it, and figured we should have a place to discuss it. The TV landscape needs more real, good sci-fi: there's not a lot of it left, even on the moronically renamed Syfy channel. But maybe this one will have a solid season. I just hope that future episodes don't have so many commercials. I couldn't believe how many ads appeared during this thing.

nk497 writes "Steve Ballmer has admitted Microsoft's licensing is too complicated and contains too much fine print, but has no plans to change it at the risk of angering shareholders — and even customers who benefit from the confusion. "I'm sure we have fine print we don't need. We're not saints," he said, adding that customers have a way of figuring out how to pay the least amount of cash possible to use Microsoft's software. "Customers always find an approach which pays us less money.""

SkinnyGuy writes "Carbon nanofibers and nanotubes are the future of computers, cars, energy and more, but it won't happen until someone figures out how to make carbon nanotubes more efficiently and in formations that can deliver enough energy and functionality to offer practical solutions for real-world problems. Honda's latest breakthrough could be the first step. Of course, Intel is working on similar carbon nanotube fabrication technology. Whoever finally delivers a practical solution, it sounds like a win-win for us."

Techdirt points out a great postmortem for the Rocky Mountain News, a newspaper that ended up shutting down because they couldn't adapt to a world beyond print. While long, the talk (in both video and print) is incredibly candid coming from someone who lived through it and shares at least some portion of the blame. "It seems like pretty much everything was based on looking backwards, not forward. There was little effort to figure out how to better enable a community, or any recognition that the community of people who read the paper were the organizations true main asset. ... The same game is playing out not just in newspapers, but in a number of other businesses as well. Like the Rocky Mountain News, those businesses are looking backwards and defining themselves on the wrong terms, while newer startups don't have such legacy issues to deal with."

eldavojohn writes "OnLive is a new cloud gaming service that is in beta testing. While it might sound like nothing more than corporate buzzwords creeping over into the gaming world, a new video reveals how the CEO claims his service will work. Perlman explains OnLive's solution to the video game compression problem and talks about the '80 ms latency budget.' It's pretty interesting to listen to him figure out this budget and where the 'costs' come from. (Video only.) Now, this all hinges on the 'microconsole,' which — as he reveals at the beginning of the video — is so cheap they plan to give it away. We may also see it incorporated with TVs and other electronic devices. He goes on to talk about perceptual science and dealing with packet irregularities on the internet."

slak11 quotes from a Globe and Mail article on the jump in corporate and government security breaches year-over-year. (The reporting is from Canada but the picture is probably much the same in the US.) "This does not seem to be all that newsworthy these days, since stories like this are appearing on a regular basis. The one detail I did like — that seems to break from the traditional 'hackers cause all the bad stuff' reporting — is the mention that everyday employees are a major cause of breaches. The recent Rocky Mountain Bank/Google story is a perfect example. As stated in the article: 'But lower security budgets aren't the only reason breaches tend to soar during tough economic times — employees themselves can often be the cause of such problems.' I figure this will be an ongoing problem until company management and employees accept their role in keeping company information safe. And IT people need to understand that regular employees are not propeller-heads like Slashdot readers, and to begin to implement technology and processes that average people can understand and use."

selven wrote in with something a bit offtopic for Slashdot, but I figured it's worth a discussion today. He writes "Following Iran's revelation regarding its secret nuclear enrichment plant, western leaders are banding together against it, saying that it violates Articles 2 and 3 of the Non-Proliferation Treaty and suggesting serious sanctions against the country if it refuses to back down on its uranium enrichment program. Iran maintains that its nuclear program is for peaceful purposes only and that it's not fair for the US to be criticizing them in this way while having thousands of nuclear warheads."

In a recent article for Offworld, Jim Rossignol writes about how the experiences offered by games are broadening as they become more familiar and more popular among researchers and educators. He mentions Korsakovia, a Half-Life 2 mod which is an interpretation of Korsakoff's syndrome, a brain disorder characterized by confusion and severe memory problems, and makes the point that games (and game engines) can provide interesting and evocative experiences without the constraint of being "fun," much as books and movies can be appreciated without "fun" being an appropriate description. Quoting: "Is this collective imagining of games one of the reasons why they tend to focus on a narrow band of imagination? Do critics decry games because games need, more than any other media, to be something a group of people can all agree on? Isn't that why diversions from the standard templates are always met with such excitement or surprise? Getting a large number of creative people to head out into the same imaginative realm is a monumental task, and it's a reason why game directors like to riff off familiar films or activities you can see on TV to define their projects. A familiar movie gets everyone on the same page with great immediacy. 'Want to know what this game is going to be like? Go watch Aliens, you'll soon catch up.' We are pushed into familiar, well-explored areas of imagination. However, there are also teams who are both exploring strange annexes and also creating games that are very much about imaginative exploration. These idiosyncratic few do seem like Alan Moore's 'exporters,' giving us something genuinely new to investigate and explore. Once the team has figured out how to drag the thing back from their imaginations, so we get to examine its exotic experiences — like the kind we can't get at home."

An anonymous reader writes "We recently developed a multi-user application and deployed it to our users. This is a web-based application that used to be a Windows application which was written in Delphi using Paradox databases for the client database. In the Windows application, we used the ability in Paradox to lock records which would prevent users from editing the same data. However, in the web application we did not add in a locking facility for the data due to its disconnected nature (at least that's how I was shot down). Now our users are asking to have the locking back, as they are stepping on each others' edits from time to time. I have been assigned to look at best practices for web application locking of data, and figured I would post the question here to see what others have done or to get some pointers to locations for best practices on doing locking with in a web application. I have an idea of how to do this, but don't want to taint the responses so I'll leave it off for the time being."
