YouTube - Walt Disney's Original Plan for EPCOT - Part 2
Walt Disney’s original vision for his Experimental Prototype Community Of Tomorrow (EPCOT) is astounding.

Unfortunately, what was later opened as “EPCOT Center” is only a terribly faint echo of the original vision.

Tinkerer’s Sunset [dive into mark]
Mark Pilgrim laments that the closed nature of next generation of computing devices (“New World” devices as described by Steve Frank) will mean an end to curious folks (especially kids) learning to hack (in the traditional sense). Other folks argue that the hacker spirit has always found an outlet, despite the ever increasing prevalence of closed environments and complexity. It does seem likely that some potential hackers would be discouraged if all the devices at hand are more closed than open. Still others argue that the creativity channeled into hacking will move into other areas (instead of hacking hardware (already a much withered past time) or even software, they will start to hack content (HTML, JavaScript, etc.)).

AlphaGrip All-in-One Gaming Keyboard, Ergonomic Keyboard, and Ergonomic Trackball
A keyboard shaped like a game controller. Interesting, but it has never been my experience that game controllers offered a stress-free method of input. The treadmill demo was a neat example of an atypical use where it would be much better than a keyboard.

The SSD Relapse: Understanding and Choosing the Best SSD
This and the previous SSD articles ("X25-M Review" and "SSD Relapse") have lots of good info a SSDs in general and the various implementations out there.

It used to be that the only viable option was Intel (the lower-cost drives all suffered one performance defect that put them at worse-than-platters performance). Now there is at least one other lower-cost, competitive chipset out there and it is sold in several variations by multiple vendors.

Schneier on Security: Helping the Terrorists
Much infrastructure is helpful to terrorists. But just about all of it is of much greater use to the general public. Just because some aspect of general infrastructure (whether it is information technology or not) is useful to terrorists does not mean it should be banned.

Cellphone antenna booster sticker test and analysis
An attempt to scientifically test cell phone antenna booster stickers. The major flaw was that the testing procedure did not follow the sticker's manufacture's instructions (because by doing so, it would be impossible to repeatedly test the same phone with and without a sticker).

» Shirky and Overload Lispian: Random meanderings on whatever catches my fancy
Embedded video of Clay Shirky giving a talk about information overload. The main idea is that technological communication is fundamentally different from normal in-person communication. Filters that are automatically engaged in in-person context are usually non-existent in technological contexts.

Changing one's relationship status on (e.g.) Facebook causes outbound information overload.

Spam, (RSS) feeds, and even normal email are a examples of inbound information overload.

Virtual study groups are something of a hybrid. The students want to leverage the technology, but the universities might see it as cheating.

When faced with information overload, ask "what filter just broke?".

Want to Remember Everything You'll Ever Learn? Surrender to This Algorithm
Some background in memory research and some bits of interview with an "accidental" memory researcher that has developed an algorithm called spaced repetition. The idea is usually structured around the concept of flash cards. The difference is that the algorithm manages which cards are presented and how often each card is presented. It delays the repetition of cards for which the user indicates a strong recall and brings forgotten or weakly remembered cards back more often to strengthen recall.

The idea is that the best time to remember something is right when you are about to forget it. The repeated application of this process moves the information into long term memory.

Straight out of Compton
A Mac pundit's view of the new Google browser named Chrome. He is impressed by its minimalism and fresh approach to the interface.
Some of the technical details are interesting too. Each tab gets its own process (or multiple processes when plugins are used). The other tabs are still responsive when one tab is loading or hung up in JavaScript land. There is also a new JavaScript engine that uses a VM with JIT compilation to machine code and precise, incremental GC. It also puts the processes in "jails" so that they can not affect other parts of the computer.

Analog Meets Its Match in Red Digital Cinema's Ultrahigh-Res Camera
About a new digital movie camera system that captures images comparable in quality to film (4096x2304, same sensor size as normal film). Designed by the guy behind Oakley sunglasses. Uses many technologies that were invented specifically for this camera (a new loss less video codec for RAW footage, new technology single chip sensor). While still expensive ($17.5k, body only?), it is much cheaper than film cameras ($25k/month to RENT) and other, professional-grade, but lower-resolution digital video cameras ($150k).

Using Photographs to Enhance Videos of a Static Scene
A paper and demonstration video that combines still photography and dynamic video footage (panning, camera movement, small lighting changes, etc.) of the same mostly static scenes to enhance the video: fix exposure (including high dynamic range exposures), enhance resolution, remove blemishes and prominent foreground objects, edit/replace still images (e.g. framed pictures in a video sequence), provide much better vibration reduction.
The technique builds physical models of the scene by analyzing the video and photographs for depth and reconstructs the video using information derived from other parts of the video as well as the still photographs.

Zeitgeist - The Movie
Two 2+hr movies.
First: 3 parts: many religions are based on astrological myths & used as controls for the masses; 2001-09-11 was an "inside job" as a pretense to war; banking concerns pushed USA into WW1/2, Vietnam, Afghanistan/Iraq & are pushing to a one-world govt.
Second: More on the monetary system: money = debt. How 'economic hitmen' have been a key tool in pushing foreign governments into positions of exploitation. Some description of The Venus Project as a sustainable, technology-driven, resource-based way of (post scarcity) global life. Two universal truths are emergence and symbiosis and how current institutions (finance, government, religion, etc.) are all geared against them.
