Comment Square to hexagon conversion (Score 5, Interesting) 142

Civ 4 map plots are squares. Civ 5 are hexagons. I don't see an easy conversion process that won't produce real not-just-semantic map differences (e.g. how to convert diagonal waterways where in a 4x4, one diagonal is water and the other diagonal is land, and ships can travel through the water diagonal?)

Are Googlers Too Smart For Their Own Good? 307

theodp writes "If you're a mere mortal, don't be surprised if your first reaction to Google Storage for Developers is 'WTF?!' Offering the kind of 'user-friendly' API one might expect from a bunch of computer science Ph.D.s, Google Storage even manages to overcomplicate the simple act of copying files. Which raises the question: Are Googlers with 'world-class programming skills' capable of producing straightforward, simple-to-use programming interfaces for ordinary humans?"

Next-Gen Augmented Reality Rears Its Unreal Head 49

andylim writes "Separate teams at Oxford university and Zentium, a South Korean company, are working on next-gen augmented reality solutions, which make it possible to fuse real and 3D computer-generated visuals on the fly using mobile phones. The team at Oxford university has named its solution Parallel Tracking and Mapping (PTAM) and it has licensed its technology to QderoPateo LLC, which has ambitious plans to grow the mobile augmented reality market and create an augmented reality search and gaming engine running for its 'Ouidoo' smart phone. Zentium's solution is called D-Track and is being used to develop the first markerless mobile augmented reality pet, called iKat. D-Track's mapping technology is very similar to PTAM and allows your phone to recognise the space in front of the camera and create an appropriate space for an augmented reality object or pet."

I don't think AMD cares that much if Linux gets subpar drivers, given its low marketshare and audience. Macs might be a different story, and their reliance on OpenGL could get AMD to care more about it.

Comment Re:PC Gaming! (Score 1) 201

This is more a critique against PC gaming rather than a critique of this new beast. It is absolutely stupid to think that you need this GPU to "match" the 360 - PCs have already surpassed the 360 and PS3 a while ago in the budget range. You ARE aware that there are GPUs in $50 range that are more powerful than the one bundled with the XBOX 360, right? Heck, there a LAPTOP GPUs that are better than the 360.

PC gaming has its obvious advantages besides better graphics, namely the trusty keyboard & mouse and modability. MMOGs typically require keyboards, and any game that emphasizes modding is likely to be a better experience on the PC, e.g. I pity those that bought the console versions of Dragon Age.

Comment Windows 7 should be 64 Bit (Score 0, Offtopic) 397

(Sorry, this is somewhat offtopic, but it was the first thing I thought of when I saw the comparison between Windows XP and Windows 7.)

I once saw someone here on Slashdot mention that Microsoft should not have shipped a 32-bit version of Vista, opting instead to push only the 64-bit version. While it seemed like an odd statement at the time (despite the fact that my home XP machine was an AMD64 processor), I find myself agreeing with it on Windows 7.

As it stands today, 32-bit Windows is quickly becoming too small for many business and industrial uses, and it's very affordable to build a high-performance home machine with more than 4GB of RAM. (Case in Point.) In fact, with intensive web applications and sophisticated desktop tools (yeah, some of them are bloated) chewing more memory than ever before, it just doesn't make sense to get anything less than 4GB (nay, 3GB if you're running Windows 32-bit!) except for a few edge cases.

Unfortunately, Windows has been kind of lagging on the 64-bit front. By treating it as sort of a bastard child (like they treated all their non-i386 NT versions), Microsoft managed to ensure that hardware manufacturers wouldn't make an effort to support 64-bit windows in a non-server environment. Which is frustrating as I've started bumping up against that once-awesome 4GB barrier.

In an attempt to turn this into a slightly more useful conversation rather than a one-sided rant, I was wondering if I could get some opinions on using virtualization as a solution? With Windows' poor track record as a 64-bit OS, I have been thinking about running a 64-Bit Unix and virtualizing 32-bit windows for backward compatibility. I've already had some success with virtualizing Windows 7 on a MacBook, and have even been able to get desktop integration working. (Quite spiffy that. Though the two interfaces occasionally confuse my wife. She's the primary user of Windows, needing support for some specialized programs with no real alternatives available.)

Does anyone here have experience with setting up a system like this? Do you use Xen, VMWare, Sun VirtualBox/OpenxVM, or some other solution? What do you use as your primary OS? Linux has come a long way, but the upgrade treadmill is still frustrating. Especially with the seemingly regular ABI upgrades. Does anyone use [Open]Solaris x86_64 as a host? Do you have 3D Graphics completely disabled, or have you found a good way to allow all OSes solid and reliable access to the underlying graphics card? Do you bother with mounting virtual shared drives to move data between the OSes, or do you have a home NAS for storing data? (I'm leaning toward a NAS myself.)

Just a few thoughts, anyway. Thanks in advance for experiences & suggestions! :-)

Comment Re:Videogames in 1982? (Score 4, Informative) 320

Wasn't Wolfenstein, released in 1992 the first game with 3D graphics?

Not even close. Wolfenstein wasn't even the first raycaster game. It was preceded by Catacombs 3D (also by Id) which itself was preceded by Hovertank (also by Id).

Before those were even a twinkle in Carmack's eye, we had MIDI Maze (1987) and Star Wars Arcade (1983), just to name a few. There were tons of attempts at 3D games before Carmack. He merely popularized the First Person Shooter genre and made 3D Graphics the standard.

Comment Re:This is the nature of medical science (Score 3, Informative) 205

The problem here is in trying to patent a trade secret rather than an invention. Patents are intended to cover inventions. Real, working gizmos that operate is a specific fashion. Trade secrets cover processes and information that is of a competitive advantage.

In this case, the two are getting mixed up. The company may have a device to detect certain attributes (which IS patentable) but the fact that the attributes can be measured in order to draw conclusions is inherently unpatentable. If someone else develops a machine for measuring the attributes that works different from your machine... well... tough noodles.

All that can be done is to keep the information a secret. By keeping it secret, it is legally viewed as a "trade secret" which can be contractually protected when sharing with interested parties.

I happen to agree with the GP, and I've written tons of games in the past 40 years. Here's my Atari 2600 version of Lunar Lander:

Run it through an emulator like Stella to play.

I later ported the game to Flash, but it's not quite as fun as the 60Hz 2600 version. However, you can play it on a Wii! (Use S for thrust if you're on a PC.)

Comment Re:If Apollo program had continued (Score 1) 389

That was one variation of the term "computer". But as my old fashioned flight computer can attest to, slide rules were often referred to as computers as well.

It's interesting listening to some of the vets from WWII. They'll often talk about their "trajectory computers" or their "bombing computers" or their "landing computers". To the modern ear, it sounds like they're talking about early electronic machines. Yet these references are just specialized slide rules used to "compute" results for a set of measurable inputs.

The Saturn V could lift more than double the shuttle's cargo capacity

I addressed this above. The Shuttle Transport System has better power output, but it has to waste it on carrying a giant airplane into space. The Saturn V was less powerful, but far more flexible. Put whatever you want on top and it gets to space. That often meant the Apollo capsule/command module/lander/moon equipment combo with sufficient velocity to make lunar orbit, but also occasionally meant a huge hulk of steel and solar panels like SkyLab.

The Saturn V boosters were detuned as well.

I'm not talking about detuning. I'm talking about reducing engine output once maximum dynamic pressure is reached. If the SRBs maintained maximum thrust, they'd push the shuttle beyond its structural limits.

From Wikipedia:

The propellant is an 11-point star-shaped perforation in the forward motor segment and a double-truncated-cone perforation in each of the aft segments and aft closure. This configuration provides high thrust at ignition and then reduces the thrust by approximately a third 50 seconds after lift-off to avoid overstressing the vehicle during maximum dynamic pressure (Max Q).

What you're referring to is the resonance problems inherent in the engine vibration of the F-1 engines. i.e. The "pogo" effect. As I recall, this issue is currently the biggest challenge facing the Ares I stack. The Space Shuttle was vulnerable to some pogo effect, but adding dampeners to the LOx fuel lines was sufficient to prevent the effect.
