maczealot writes "Google is launching a new 'Copyright School' for use as a re-education tool for offenders on YouTube. The apparent purpose being to head off additional legislation, lawsuits, regulation and other negative impacts to the site. They even have campy cartoon videos for this school."

An anonymous reader writes "YouTube has already live-streamed a number of popular concerts, sporting events, and interviews, but most were one-time deals. Now Google wants to crank it up a notch, and has announced YouTube Live. YouTube Live integrates live streaming capabilities and discovery tools directly into the YouTube platform. From the announcement: 'Today, we'll also start gradually rolling out our live streaming beta platform, which will allow certain YouTube partners with accounts in good standing to stream live content on YouTube. The goal is to provide thousands of partners with the capability to live stream from their channels in the months ahead. In order to ensure a great live stream viewing experience, we'll roll this offering out incrementally over time.'"

An anonymous reader writes "In this tongue-in-cheek video, researchers at the USC Institute for Creative Technologies take playful jabs at Google as they demonstrate their software controlling Gmail with a Microsoft Kinect sensor. The gesture controls are strikingly similar to those jokingly suggested by Google in their fictional Gmail Motion application, posted as an April Fools' day prank. The researchers have made their software available for free on their website."

mikejuk writes "Microsoft Research has just published a scientific paper (PDF) and a video showing how the Kinect body tracking algorithm works — it's almost as impressive as some of the uses the Kinect has been put to. This article summarizes how Kinect does it. Quoting: '... What the team did next was to train a type of classifier called a decision forest, i.e. a collection of decision trees. Each tree was trained on a set of features on depth images that were pre-labeled with the target body parts. That is, the decision trees were modified until they gave the correct classification for a particular body part across the test set of images. Training just three trees using 1 million test images took about a day using a 1000-core cluster.'"

Escape area if safe to do so or shield/secure your location.' (Univ. of Illinois, 2011). An alert message sent out Thursday to 87,000 emails and cell phones warning recipients to escape from an 'active shooter' at the University of Illinois was an error, the Office of the Chief of Police confirmed. 'The alert sent today was caused by a person making a mistake,' explained an email. 'Rather than pushing the SAVE button to update the pre-scripted message, the person pushed the SUBMIT button. We are working with the provider of the Illini-Alert service to implement additional security features in the program to prevent this type of error.'"

theodp writes "The WSJ's Elizabeth Bernstein reports that Reply All is still the button everyone loves to hate. 'This shouldn't still be happening,' Bernstein says of those heart-stopping moments (YouTube) when one realizes that he or she's hit 'reply all' and fired off a rant for all to see. 'After almost two decades of constant, grinding email use, we should all be too tech-savvy to keep making the same mortifying mistake, too careful to keep putting our relationships and careers on the line because of sloppiness.' Vendors have made some attempts to stop people from shooting themselves in the foot and perhaps even starting a Reply All email storm. Outlook allows users to elect to get a warning if they try to email to more than 50 people. Gmail offers an Undo Send button, which can be enabled by setting a delay in your out-bound emails, from 5-30 seconds, after which you're SOL. And AOL is considering showing faces, rather than just names, in the To field in a new email product. 'I wonder if the Reply All problem would occur if you saw 100 faces in the email,' AOL's Bill Wetherell says."

An anonymous reader writes "In the wake of Nokia's announcement that it will be cheerfully throwing its existing developer community under a bus by not offering Qt for Windows Phone, a project to implement Qt on Android has announced its initial alpha release. Necessitas project lead Bogdan Vatra writes, 'I had a dream that one day, I'll be able to deploy existing Qt software on any Android platform. I had a dream that one day, all Qt applications will use system wide shared Qt libraries. I had a dream that one day, all Qt applications once compiled and deployed to one android platform, will run on any other newer android platform and will last for years without any recompilation. I had a dream that one day, I'll be able to create, manage, compile debug and deploy Qt apps using a first class citizen IDE. Now, those dreams become reality.' The Necessitas wiki offers some documentation on Qt for Android. A demo video of Qt for Android in action is also available."

GameboyRMH writes "If you were impressed at the remote-controlled ornithopters released in recent years, then this will really knock your socks off: In the 1970s, the CIA developed and tested a remote-controlled ornithopter that was disguised as a dragonfly — and at roughly the size of a dragonfly. It was intended to be used as a platform for listening devices. This 'insectothopter' was laser-guided and powered by a tiny gasoline engine built by a watchmaker. While its performance was impressive, difficulty controlling the tiny craft in crosswinds made it impractical, and the idea was scrapped. The article also mentions a robo-squid, and has information on a remote-controlled fish (video) that is also very impressive."

ericatcw writes "Despite the strong inroads that mobile devices are making (see this online list of mass iPad rollouts), many skeptics remain unconvinced of their usefulness. That's true even when confronted with news of Microsoft's fear, reasoned arguments, or even old-timey anti-laptop rants that, hilariously, echo all of the same criticism today against tablets. Will this Xtranormal cartoon video depicting two furry woodland creatures on opposite sides of the 'Tablet or PC?' debate sway your mind?"

vbraga writes "The Antikythera Mechanism is the oldest known scientific computer, built in Greece at around 100 BCE. Lost for 2000 years, it was recovered from a shipwreck in 1901. But not until a century later was its purpose understood: an astronomical clock that determines the positions of celestial bodies with extraordinary precision. In 2010, a fully-functional replica out of Lego (YouTube video) was built."

An anonymous reader writes "30 years before words like performance capture, augmented reality, or avatars were around — let alone commonplace — experimental film and video artist Tom DeWitt created a system that features aspects of all of them. Pantomation let users interact in real-time with a digital environment and props. It was built using Apple IIe's, analog video gear, and lots of custom hacking and patching. He's currently working on a holographic 3D system that's similarly ahead of its time."

TechieAlizay points out a post at Geekword.net about a man who hacked Microsoft's Kinect to play Max Payne. "This hack was possible due to FAAST (a toolkit for Kinect), OpenNi/Nite and GlovePIE. Here's how the hacker describes the different control gestures: 'As you can see, the leaning left and right stuff is all there – and moving your body forward and back moves you back and forward. The reload and interact gestures are becoming pretty standard for me now, and pain killers are popped with an upward motion of the left hand. What makes this special though is the leg movements that activate bullet time. The result is bullet time diving for real! When this game hit just after the Matrix film came out, it caused a big stir – with Kinect augmentation it gets even better. The one thing that needs fixing is weapon select; this will be handled by the +/- buttons on the mote in future, I think.'" Another video shows Kinect controlling Left 4 Dead 2. In addition to future PC support, Microsoft is reportedly working on an official SDK. Yet another recent hack of note allows a human to control a humanoid robot with an impressive level of accuracy. Just be careful if you play the Kinect boxing game; somebody might call the police.

The controller is built without a microprocessor or even digital logic. It does use a gyroscope like the real Segway. The functionality looks fairly basic, but the fact that the controller works at all is amazing. The guy has a ton of other projects on his site too. Definitely worth a read for people who enjoy building things."

minterbartolo points out this video, produced by Matt Melis at the Glenn Research Center, excerpting from its description: "Photographic documentation of a Space Shuttle launch plays a critical role in the engineering analysis and evaluation process that takes place during each and every mission. Motion and Still images enable Shuttle engineers to visually identify off-nominal events and conditions requiring corrective action to ensure mission safety and success. This imagery also provides highly inspirational and educational insight to those outside the NASA family. This compilation of film and video presents the best of the best ground-based Shuttle motion imagery from STS-114, STS-117, and STS-124 missions. Rendered in the highest definition possible, this production is a tribute to the dozens of men and women of the Shuttle imaging team and the 30yrs of achievement of the Space Shuttle Program."

eldavojohn writes "A Japanese/Algerian effort called The Sahara Solar Breeder Project employs a simple concept revolving around the pure silica in the sand of the Sahara Desert. The silica can be used to build vast solar arrays which will then provide the power and means to build more solar arrays in a classic breeder model. They would then use DC powerlines utilizing high temperature superconductors. The lead of the project points out that silica is the second most abundant resource in the Earth's crust. The project's lofty goals to harness the Sahara's energy has a few requirements — including 100 million yen annually — but also the worldwide cooperation of many nations and the training of the scientists and engineers to create and man these desert plants. The once deadly wasteland of the Sahara now looks like a land rich in an important resource: sunlight."

An anonymous reader writes "The TSA isn't the most respected of governmental agencies right now, but at least it comes by the poor reputation honestly. The lack of standards, inconsistent application of searches and policies, and occasional rude agent all combine to make flying an unpleasant experience. It's often derided as 'security theater,' which describes the experience of Mythbuster Adam Savage before a recent flight. Savage was put through the full-body scanner, and while he joked that it made his penis feel small, no one seemed to notice the items he was carrying on his person. The video tells the rest of the story."

On Nov. 15th, Facebook CEO Mark Zuckerberg introduced Facebook Messages, which uses whatever method of communication is appropriate at the time — e.g., email, IM, SMS. A day later, ex-Apple software engineer Jens Alfke was granted a patent for his 2003 invention of a Method and apparatus for processing electronic messages, which — you guessed it — employs the most appropriate messaging method — e.g., email, IM, SMS — for the job. Citing Apple's lack of passion for social software, Alfke left Apple in 2008. After a layover at Google, Alfke landed at startup Rockmelt, whose still-in-beta 'social web browser' also sports a pretty nifty communications platform."

Gibbs-Duhem writes "This awesome video was produced by some MIT engineers recently. They've started a fully open-source, open-hardware high power LED lighting project that they designed to be modular enough to control with the Arduino (or any other control system). Using their open-source firmware, you can set up the Arduino to connect to Wi-Fi and receive Open Sound Control packets. Then, they went further and released open-source software for PureData and Python to do music analysis and make the lights flash brilliantly in time with the music! A full Instructable was also posted in addition to the existing documentation for design and assembly on their website."

A few more details are available on a forum post the man made. Adafruit said the bounty could be his if he posts the source code, and they also upped the reward to $3,000 in response to another silly statement from Microsoft.

CWmike writes "A computer security researcher says he plans to release code Thursday that could be used to attack some versions of Google's Android phones over the Internet. The attack targets the browser in older, Android 2.1-and-earlier versions of the phones. It is being disclosed Thursday at the HouSecCon conference by M.J. Keith, a security researcher with Alert Logic. Keith says he has written code that allows him to run a simple command line shell in Android (video) when the victim visits a website that contains his attack code. The bug used in Keith's attack lies in the WebKit browser engine used by Android. Google said it knows about the vulnerability. 'We're aware of an issue in WebKit that could potentially impact only old versions of the Android browser,' Google spokesman Jay Nancarrow confirmed in an e-mail. 'The issue does not affect Android 2.2 or later versions.' Version 2.2 runs on 36.2 percent of Android phones, Google says"

A video shows how the Soviets went about restoring damaged images with the help of rotary scanners, magnetic tape, and trackballs. No word on whether this technology was used to fake moon landings or put missiles in Cuba." Photo manipulation in the USSR (and elsewhere) had a pretty good jump on computers, though.

chrb writes "BBC News and the Telegraph are reporting that the British government has pressured the US government to take down privately hosted extremist web sites and videos, particularly on YouTube. The request follows the conviction of a 21-year-old woman who attempted to murder MP Stephen Timms after watching YouTube videos of radical American Muslim cleric Anwar al-Awlaki. YouTube hosts more than 5,000 videos featuring al-Awlaki, but has begun to remove them following the British government's complaints. The issue obviously raises First Amendment issues in the US, but Security minister Baroness Neville-Jones has said 'Those websites would categorically not be allowed in the UK. They incite cold-blooded murder and as such are surely contrary to the public good. If they were hosted in the UK then we would take them down but this is a global problem. Many of these websites are hosted in America and we look forward to working even more closely with you to take down this hateful material.'"

vsedach writes "Remember the 1980s and BASIC, when programming was simple, brains flew through space, and everyone ate lasers? Computer magazines came with code listings, and classics like David Ahl's BASIC Computer Games offered a fun and easy way to get started in computer programming. Conrad Barski remembers, and with Land of Lisp, he's set out to demystify programming in the 21st century." Keep reading for the rest of Vladimir's review. Land of Lisp: Learn to Program in Lisp, One Game at a Time! author Conrad Barski, M.D. pages 504 publisher No Starch Press rating 10 reviewer Vladimir Sedach ISBN 978-1-59327-281-4 summary Learn to Program in Lisp, One Game at a Time! This is no small feat. Modern computers don't come with anything that looks like BASIC. Getting started with a "real" programming language like Java requires installing and learning hundreds of megabytes worth of compiler and integrated development environment. Barski's thesis is that Lisp is a refreshing alternative - it offers BASIC's ease of getting started (get a prompt, type in code, and it works), while providing a combination of modern features unmatched in other programming languages.

The first thing that immediately jumps out about Land of Lisp is that it has a lot of comics. The book is an outgrowth of Conrad's Casting SPELs in Lisp illustrated online tutorial, which originally appeared in 2004 (incidentally, around the same time as why's (poignant) guide to ruby, probably the most famous and epic programming language comic book). The comics are humorous and irreverent - if you're a C programmer, you might be surprised to know that you're a Cro-Magnon fighting the COBOL dinosaur.

Despite the silly humor and Barski's approach of introducing programming completely from scratch, Land of Lisp builds up to cover topics like graph theory, search algorithms, functional and network programming, and domain-specific languages. All throughout, the book emphasizes various techniques for doing I/O. The topics covered will leave the reader with a solid understanding of what modern programming entails and a good basis from which to explore either application or lower-level systems programming.

The most unintentionally impressive aspect of Land of Lisp is that it manages to completely explain web programming. No more hiding behind complicated software stacks and impenetrable web server packages - chapter 13, titled "Let's Create a Web Server!," does exactly what it promises, in only 15 pages. Later chapters introduce HTML and SVG to build a graphical game as a web application. If nothing else, this book will leave the reader with all the necessary basic skills and total confidence in their understanding to build real-world web applications.

Other introductory programming books use Lisp, but none fall into the same category as Land of Lisp. Abelson, Sussman and Sussman's Structure and Interpretation of Computer Programs, arguably the greatest introductory programming book ever written, requires a solid math background to understand the examples. Felleisen et alia's How to Design Programs offers a much deeper introduction to programming than Land of Lisp, but is an academic textbook, and hence lacks funny cartoons and may be boring. Friedman et alia's The Little Schemer is a favorite of many, but doesn't have LoL's real-world applications.

Land of Lisp is an excellent book for someone who wants to learn how to program, for web programmers who want to move up out of their niche and start learning about CS theory and systems programming, and for anyone who is puzzled about what really goes on behind the web and wants to learn what web programming is really about. Experienced programmers who want to jump into using Lisp are probably better off with Peter Seibel's Practical Common Lisp, though.

Watch Conrad's hilarious promotional music video for the book.

Andrew Smith writes "John Carmack has an article up on the Bethesda blog discussing the iPhone/iPad version of RAGE, which is said to run at an impressive 60fps. 'Managing over a gig of media made dealing with flash memory IO and process memory management very important, and I did a lot of performance investigations to figure things out. Critically, almost all of the data is static, and can be freely discarded. iOS does not have a swapfile, so if you use too much dynamic memory, the OS gives you a warning or two, then kills your process. The bane of iOS developers is that "too much" is not defined, and in fact varies based on what other apps (Safari, Mail, iPod, etc) that are in memory have done. If you read all your game data into memory, the OS can’t do anything with it, and you are in danger. However, if all of your data is in a read-only memory mapped file, the OS can throw it out at will.' And a tweet by Carmack yesterday suggests that an Android version of RAGE is on the way too."

As World of Warcraft prepares for the launch of its third expansion, Cataclysm, on December 7th, the design team is busily trying to finish all the new high level content, the destruction and rebuilding of Azeroth, and major changes to many of the game's systems and classes. At Blizzcon we spoke with Greg Street (a.k.a. Ghostcrawler), Lead Systems Designer for WoW, about Blizzard's goals for this expansion, the problems they're trying to solve, reasoning for the creation of a few new features, and why they aren't willing to simply throw more people at complicated projects. Read on for our discussion about World of Warcraft: Cataclysm.

Slashdot: With the previous expansions, it seems like one of the goals has been to make things more inclusive for raiders. Do think you've reached the end of the road in that regard? Are there still goals for the future?

Greg Street: We've got a lot of players into raiding now. I don't encounter too many players these days who say, "I want to raid but I'm not sure how," or "It's too hard." Particularly, the raids underneath Wintergrasp and soon Tol'Barad are super-easy for any group to just pick up and go do quickly. So I think we're doing a good job of being inclusive there. I think we need to, perhaps, pay a little more attention to the super-hardcore guys who felt a little neglected at times in Wrath of the Lich King.

Slashdot: These days the design team is working on solving social and psychological problems perhaps more than technical problems. What types of those are you working on now?

Greg Street: Something that has come up a lot is that cross-server battlegrounds and then the dungeon finder going cross server has eroded the sense of community within a server. It used to be, "I knew these guys," or "He was the best mage on the server," or things like that. It's much harder to identify that now. And another thing is the ability to hop from server to server so easily now. One of the things we're doing to work against that, a little bit — Tol'Barad will be like Wintergrasp, in that it's just your server, so hopefully you can get to know people a little better there. And then the big push we're making for guilds in Cataclysm. You're going to have achievements, and [you'll be able to] level your guild. It's something you can work together with your closest friends to try to accomplish.

Slashdot: Do you think that will supplement the permanence of guilds, making it easier for people to keep their guilds going?

Greg Street: I think the guild itself will mean something, and people will be reluctant to give up a guild they worked really hard on. I mean, it won't be impossible — we're not trying to fetter people too much.

Slashdot: For Cataclysm you're increasing health pools significantly, not to mention all the other numbers. Is mudflation becoming an issue for you?

Greg Street: We're pretty confident that the curve we have overall can keep going almost indefinitely. The numbers are solid in most cases. We used to have a problem where, say, critical strike rating can't go up any higher, because it's at 60 or 70 percent. The way combat ratings work now, I don't think we're in danger of the combat systems collapsing on themselves because of the numbers. I think we are at risk for them becoming hard to manage. Once players are saying, "I have 17,000,000 health," and everything just has so many zeroes on it, at that point we'll have to do something. I don't know if it's just lopping three zeroes off of everything, or what. I think the human brain loses the ability to parse numbers once they get beyond a certain size.

Slashdot: For heroic dungeons, are you trying to copy what you did in Wrath of the Lich King? How are those evolving?

Greg Street: I think the heroic dungeons will feel a little more like Burning Crusade. Hopefully it will be the best of Lich King and Burning Crusade. Part of what people remember about the Burning Crusade heroic dungeons was the "17 pulls of trash in between bosses," or something like that. Hopefully we can get through that a little quicker, but still have the bosses as a challenge, something players have to learn. We think that the encounters are a failure if players can go through a boss fight, and then when we ask them, "What was that boss doing? What was special that you had to do in that fight," and they say, "Well I didn't notice anything." Then we know that they're just overpowering it instead of having to learn the encounter.

Slashdot: You mentioned in the panel on Friday that a lot of that information — boss abilities, loot lists — are going to be integrated into the game. Where do you draw the line at what's OK to have in the game and what players can be expected to go on a website and look up?

Greg Street: I think the game needs to provide players the information they need to play the game. It's fine if they are trying to improve their damage-per-second (DPS) by one extra percent by visiting a fan site or a news site. It's very frustrating with boss abilities, to use that particular example... we've all been in dungeons where the leader says something like, "He's going to do some kind of fire thing, I think it's called.. Flame..something? I don't remember, but you'll recognize it when you see it." And everybody else asks, "What?"

I think in that example, the game is just hiding information from players that they need to function. Now, you can definitely take that too far. We could get to the point where there are mods that say, "Stand here! OK, now press this button. Now stand over here." And at some point, they're playing Dragon's Lair, or something, instead of having to do a real boss encounter.

Slashdot: Speaking of mods, Cataclysm is introducing some welcome changes to the UI. How do you decide what players need to look at and what you want to integrate with the base UI?

Greg Street: That's really tough, because we want World of Warcraft to be moddable, and we support the community — both the developers who make those mods and the players who use them. We try to look at when the players are saying something is essential. We made a system to manage gear because players were telling us, "I can't play without this mod, now. This mod is so important that you guys just need to offer this functionality." We did the same thing with the big raid frames. Too many players were telling us, "Your raid frames are just not at all functional. No reasonable person is going to do a World of Warcraft raid with the standard raid frames. We won't replace everything. The QuestHelper brand of mods are something else we looked at and said, "We just need to do more here. Clearly, players are asking for it."

Slashdot: Are there any UI elements that are on your radar right now, that you're thinking about revamping?

Greg Street: I think we could do a lot more with the Auction House UI. I think our mobile and cell phone Auction House is probably superior to our in-game version at this point. And there are some mods that have done a great job -- we don't want to automate that whole experience too much, but providing the information and storing it, I think we could do better at. We'd love, someday, to do a better version of Recount, or some of the damage meters. Now, when I say better — our version sucks, which is just the combat log you have to somehow have to keep track of. Players really like to know: "What was my DPS? What could I do better this time? What were my sources of damage?" We'd love to just build something like that into the game.

Slashdot: Yesterday's Live Raid was very cool. (Blizzard invited a well-known guild to participate in set of custom raid encounters. They spawned groups of bosses that were originally designed to be dealt with on their own and had the guild fight them in groups of four at a time. At the end, the main villain of the new expansion flew in, annihilated the raid, and then began nuking one of the game world's capital cities. Longer description, YouTube video.)

Greg Street: I'm glad it worked. That was scary.

Slashdot: Has there been any discussion on getting those events out to more players?

Greg Street: That would be very cool. They require a lot of overhead and testing. One of the things people in the audience couldn't appreciate was how our encounter designer up there was changing things on the fly. He was herding bosses, in some cases killing them, and respawning things, trying to keep it all working. Obviously we can't have a human running that stuff from behind the scenes. We'd have to make sure it's cool enough. But I love this idea that Orgrimmar is being attacked and you have to defend it.

Slashdot: Azeroth is getting a complete redesign. How long have you wanted to do that?

Greg Street: Oh, forever. A really big moment was when the programmers put in a way for the level designers to make cliffs that look like real cliffs. We did that in Howling Fjord, [a starting zone in Wrath of the Lich King]. And that was huge. Up until them, all the cliffs looked like — they would call it a scoop of mashed potatoes. It's kind of this rounded blob that doesn't exist in nature. So once they could make these very sheer cliffs, they said, "OK, we've got to go fix everything, now!" Because we couldn't do this before.

Enough things like that had piled up. Originally, for Cataclysm, we thought of hitting five or six zones that were either never very good — like, say, Hinterlands — or just hadn't stood the test of time well and needed some updating. But by the time we were done, it was hard to make Darkshore look awesome, but leave Felwood looking crappy. So we ended up just doing everything.

Slashdot: That seems like a lot of work.

Greg Street: It was a stupid amount of work.

Slashdot: Compared to the last two expansions, it seems like Cataclysm contains an expansion of similar size, plus all of that revamped content.

Greg Street: That's totally true. Probably, if we had more business sense, we'd have broken it into two expansions.

Slashdot: One of the Diablo 3 team's big reveals was the PvP Battle Arenas, which are clearly similar to World of Warcraft's PvP arenas. Are we going to see more integration for the WoW arenas with Battle.net?

Greg Street: We'll have to see. The big focus for Cataclysm, as far as PvP goes, is the rated battleground system. I think too much attention had turned to arenas, and it was defining PvP for a while. For a lot of people, Warcraft was about the war; it was about the Horde or the Alliance fighting over resources, not three gnomes chasing each other around an arena. We're still supporting arenas. We like them, and there's a lot of players that like them too. We'll just have to see how much rated battlegrounds take off. There are a lot of things we can do to improve the e-sports portion of World of Warcraft.

Slashdot: With Wrath of the Lich King, you tended to schedule major content patches several months apart. Do you have a similar plan for Cataclysm?

Greg Street: Yeah. We would like to get patches out as soon as we can, because players are just voracious for content. I think there's a sense that we finished Ulduar too soon. The 3.1 patch, we could have left on a little longer — 3.2 came out a little too quickly. Whereas the final patch, 3.3, has been going on almost a year. That's too long for players to have to deal with the same content over and over. Ideally, we could get patches out every four to six months. Or, eventually we may scale them down to make them smaller but come out more often. It's definitely something we're looking at. We'd love to be able to get faster at doing that.

Slashdot: Some of the quests and dialog in the beta contain content that's a bit edgier than what we normally see in WoW. Will those things make it to live servers. Are you trying to broaden the age groups the game is designed for?

Greg Street: That's one of the fun things — we do it a lot in quest design and then item naming, too — pop culture references here and there. That's something where the Warcraft world doesn't take itself too seriously. There are some really dark, epic moments too, but then there are places we can cut loose a bit. We know players appreciate it, because the remember it and they mention that kind of stuff. You can take it too far, I think. We've had people playing the game for six years, and it's hard to offer them things they haven't seen before. So, in that sense, we do try to be a little edgier.

Slashdot: Are there any systems in Cataclysm that you'd say have improved greatly over Wrath of the Lich King?

Greg Street: Many things. I really like the new end-game point system, both for PvE and PvP. I has the advantages of the Lich King system without being so confusing and having all these vendors, and down-converting badges, and all that. I think we're really happy with the way Glyphs have ended up in Cataclysm. The original promise of Glyphs is closer to what we're able to deliver now. Seeing that awesome new UI, with the list of glyphs that you can just apply whenever you want, we're really happy with that.

Slashdot: One of your goals seems to be separating the fun choices from the math choices in building your character. Are you where you want to be with that, right now?

Greg Street: I would give us a B+ on that. I think we can still do a lot better. We're at the early stages, still, of that revamp. There are some talent decisions in trees that I think are awesome, and there are some other places where it still doesn't feel great. It feels like the obvious choice is to get this one, and this one's the trap. "Don't take this dumb talent over here." There are fewer of those, for sure, but there are still some, and we eventually need to polish all of those, too.

Slashdot: What's the solution to that? Is it adding more talents? Swapping out the bad ones you have?

Greg Street: It's more of the latter, but sometimes a new talent is the answer, too. We just have to really ask: "We thought this was going to be a compelling choice; did it end up as a compelling choice?" "If it didn't, was it because the numbers were wrong, or was it because the encounters we put players into [made it wrong]?" To use a very contrived example: if there's a talent that makes you take less magic damage, and there's not a lot of magic damage being thrown around, that talent's not going to be exciting.

A lot of our survivability talents are based around the premise that healer mana is going to matter a little bit more, so you're going to care a little bit more about trying to keep yourself alive. If everything works out well at the end of a fight, people might post the damage-taken meter, and say, "Dude, this rogue, he took a lot of damage. He was a mana hog for us." If that doesn't happen, then all those utility talents look dumb, because you don't need them, and you could have gotten something else.

Slashdot: Can you talk a bit about why the Path of the Titans system was scrapped?

Greg Street: There are two parts to that. One is that Cataclysm was an unbelievably ambitious project, and we kept adding more and more to it. I mentioned the original glyph version, and at a panel earlier I mentioned the barbershop as feature that were cool, but we could have done a lot more with them. We want to try to limit that in the future. We didn't want to release Paths and then in 5.0 be like, "OK, now we're going to fix the Path system!" We'd rather just do it right the first time.

At the same time, it was tied into a lot of other features, like Archaeology and Glyphs. Those grew a lot on their own. We realized that we were using the promise of Paths to fix up the Glyph system, when what we wanted to do was just make that system actually cool. But we love the idea of some type of end-game progression that isn't item-focused, and I think we'll return to that in the future, sometime when we can get it right.

Slashdot: We're seeing some interesting new mechanics in Cataclysm — for example, the blind dragon, which relies on hearing and makes you moderate the noise your character makes. How much of that is thinking of a fun concept and going from there, versus trying to think of a brand new, innovative concept and trying to make it fun?

Greg Street: We honestly spend a lot of time on innovation. Players are kind of merciless — "Yeah, that was a fun fight, but we've done it before," or, "This is just like that other guy." So we really try to push the envelope there on things players haven't seen before, new systems. We'll have encounter designers say, "I was playing Final Fantasy last night, and it had a boss that did this, and I think we could make that work for a boss in World of Warcraft with these tweaks."

Slashdot: A lot of players, when they hear you talk about how you didn't have time to make a feature good, their question is, "Well, why can't you just go out and hire more people?"

Greg Street: Yeah. The mythical man-month.

Slashdot: Can you explain why you don't find that to be a viable solution?

Greg Street: The other example that gets used a lot is: if it takes a woman nine months to have a baby, then if you have two women, it'd only take four and a half! Our development process is hugely based on iteration and communication. It's more important — for, say, class design and item design — it's more important for me to have a small team that's totally in sync than to have a large team and have no idea what anyone else is working on. We would end up with Hunter talents working one way, the Priest would work a different way, and it wouldn't feel polished. It wouldn't feel good to players. Often, when we say, "We didn't have time," players say, "You shipped it before it was ready." That's not the way we look at it.

The way we look at it is: we are extremely critical of our own designs. We have very long lists of things we want to fix in the game. Some of these things have been around forever, and some of the things are new that we just added recently. If we waited until we addressed every single one of those things, we would never ship anything. It would be years and years before games came out, and that's just not realistic. That's not what players want; they're not going to wait six years for a new expansion. So, instead, we do what we can and we keep other things on the back burner. We've got Paths — this great idea. A dance studio — we're going to do it some day. Just not yet. We're saving it for the right time.

Luminary Crush writes "A gas giant of approximately 1.5 Mj (Jupiter Mass) was discovered on October 22nd around the binary star system HD 176051B. It's not known with certainty which component of the binary system the planet is in orbit around at this point as both stars in HD 176051B are relatively Sol-sized (1.07 and .71 solar masses). Named 176051B b, this new exoplanet orbits within the star system's habitable zone, and if mapped onto our solar system with relative distance from our Sun it would place the large planet between Earth and Mars. While it's unlikely that such a gas giant could host life as we know it (though it's hypothesized), the location of the big planet opens up the intriguing idea of the realization of some of science fiction's famously habitable moons, Pandora and Endor. Look no further than our own solar system to see moons with the potential ingredients for life — just add heat."
