jfruhlinger writes "Upgrading your desktop PC's video card was once a rite of passage for many Slashdot readers — and could also be a gateway to building your own computer from the motherboard up. And more often than not, you bought the components from Newegg. But the tablets and ultrathin laptops that are today's hot sellers don't let you so much as swap in more RAM. What's a component retailer to do in world without user-serviceable components?"

theodp writes "Facebook CEO Mark Zuckerberg has begun personally slaying animals for food, part of a resolution to fully appreciate the meat he eats by limiting it to that which he personally kills. Zuckerberg has mostly been vegetarian since making the vow, but his hands-on kills thus far include a goat, pig, chicken and a lobster. 'He cut the throat of the goat with a knife,' Zuckerberg pal Jesse Cool told FORTUNE, 'which is the most kind way to do it.'"

Pickens writes "BBC reports that researchers have created software that gives images an expiration date by tagging them with an encrypted key so that once this date has passed the key stops the images being viewed and copied. Professor Michael Backes, who led development of the X-Pire system, says development work began about 18 months ago as potentially risky patterns of activity on social networks, such as Facebook, showed a pressing need for such a system. 'More and more people are publishing private data to the internet and it's clear that some things can go wrong if it stays there too long,' says Backes. The X-Pire software creates encrypted copies of images and asks those uploading them to give each one an expiration date. Viewing these images requires the free X-Pire browser add-on. When the viewer encounters an encrypted image it sends off a request for a key to unlock it. This key will only be sent, and the image become viewable, if the expiration date has not been passed."

devjj writes "For the past year or so I have been trying (and failing) to figure out a reasonable solution for bringing my large media library to my living room. All of my media lives on an Ubuntu server that sits on my network. It's been very reliable and it's fast enough for streaming purposes. My content is exposed via SMB. It's the living room side where I keep running into problems. I am currently using Windows 7 and XBMC, but the case is too big and noisy, I don't particularly care for Windows, and the whole thing just seems overkill. What I want is a device that can present a decent UI that the non-Slashdot crowd would be able to use, but that is still powerful enough to stream full-fidelity 1080p. I dream of a small box that can transcode video over a network, but that's probably a pipe dream. The new Apple TV would be great if it could connect to network shares. What say you, Slashdot? Is what I'm looking for possible, or should I just give in to the iTunes/Amazon/whatever juggernauts?"

boyko.at.netqos writes "In an essay entitled 'An Epiphany I Had While Playing Pac-Man,' the author talks about how smart people need to find a certain amount of intellectual challenge from day to day. If they don't find it in their workplace, they'll end up playing complex, 'smart' games, like Civilization IV or Chess — and if they do find it in their workplace, they're more likely to sit down with a nice game of Pac-Man, Katamari Damacy, or Peggle. Quoting: 'When I look back on my life, and I compare the times in my life when I was playing simple games compared to the times in my life when I was playing complex ones, a pattern emerges. The more complexity and mental stimulation I was getting from other activities — usually my day job at the time — the less I needed mental stimulation in my free time. Conversely, in times when I was working boring jobs, I'd be playing games that required a lot of thinking and mental gymnastics.' The author then goes on to speculate that some IT workers might subconsciously be giving themselves more challenges by choosing to deal with difficult problems, rather than performing simple (but boring) preventative maintenance and proactive network management."

spaceman375 writes "Like many slashdotters, I've given up on landlines and have only a cell account. The problem: when I am home I don't want to carry my phone on my person, AND I don't want to have to run (possibly up or down stairs) to answer a call. Landlines solved this with extensions. I could go buy an xlink or other Bluetooth-to-POTS solution, but that takes money for equipment. My desktop has Bluetooth, as do my laptop and cell. All I want is a program that can use my cell's Bluetooth to make and receive calls from my Linux PC. I can do this with asterisk or related programs, but that is like buying UPS when I just need a taxi ride. Yet all I can find are programs that either use 'presence' to shift other-sourced calls to my cell, or ways to use a Bluetooth headset when receiving a call on a PC. Has anyone found a way to use their desktop to make and receive calls through their cell via Bluetooth?"

We discussed the Galaxy Zoo project soon after it launched last summer. Science News is now following developments about an odd celestial object that is fueling a lot of excitement among astronomers around the world. In August, a Dutch schoolteacher named Hanny, in the process of characterizing galaxy images, noticed a peculiar object and posted a query about it on the Galaxy Zoo blog. She called it a "Voorwerp," which Science News says is Dutch for "thing" but which Google translates as "subject." Hanny's Voorwerp emits mostly green light (the earlier report said blue). The best guess astronomers have now is that the Voorwerp is emitting "ghost light," i.e. it is "lit by the ultraviolet light and X-rays from a quasar that has vanished in the last 100,000 years," to quote astronomer Bill Keel. "As far as we can tell, it's an unprecedented thing," Keel added. Researchers are scrambling to book time on the Hubble and other major telescopes to get a closer look.

SpaceAdmiral writes "The once-popular idea that the universe could be small and finite is making a comeback. Many researchers thought that a 'wraparound' universe would mean that distant objects would be seen multiple times in the sky, but new research suggests that a '3-torus' (or 'doughnut universe'), as well as other shapes, could fit our actual observations, particularly the WMAP data."

Ponca City, We Love You writes "Does time slow down when you are in a traffic accident or other life threatening crisis like Neo dodging bullets in slow-motion in The Matrix? To find out, researchers developed a perceptual chronometer where numbers flickered on the screen of a watch-like unit. The scientists adjusted the speed at which the numbers flickered until it was too fast for the subjects to see. Then subjects were put in a Suspended Catch Air Device, a controlled free-fall system in which 'divers' are dropped backwards off a platform 150 feet up and land safely in a net. Subjects were asked to read the numbers on the perceptual chronometer as they fell [video]. The bottom line: While subjects could read numbers presented at normal speeds during the free-fall, they could not read them at faster-than-normal speeds. 'We discovered that people are not like Neo in The Matrix,' Eagleman said. 'The answer to the paradox is that time estimation and memory are intertwined: the volunteers merely thought the fall took a longer time in retrospect'."

surfingmarmot writes "An HBO executive has figured out the problem with DRM acceptance — it's the name. HBO's chief technology officer Bob Zitter now wants to refer to the technology as Digital Consumer Enablement. Because, you see, DRM actually helps consumers by getting more content into their hands. The company already has HD movies on demand ready to go, but is delaying them because of ownership concerns. Says Zitter, 'Digital Consumer Enablement would more accurately describe technology that allows consumers "to use content in ways they haven't before," such as enjoying TV shows and movies on portable video players like iPods. "I don't want to use the term DRM any longer," said Zitter, who added that content-protection technology could enable various new applications for cable operators.'"

mattnyc99 writes "To motivate his new column, Popular Mechanics' Glenn Derene takes research data from a discussion here of his last column. He analyzes a new study released this week — revealing that fully 49 percent of Americans 'only occasionally use modern gadgetry' — to compare the rise of the PC with that of the TV and ask a big question: What keeps the most important and powerful communication tool since the telephone from being universally embraced?"

An anonymous reader writes "CNET wonders if 'Apple is about to frag the gaming community with a revelation that could shake Microsoft to its core: Apple will buy Nintendo. What could be more quintessentially left-field Apple behaviour than buying out the U.S.'s number three games console manufacturer?' The article goes on to compare the companies, saying 'both have followings whose brand dedication verges on the religiously devout' and design styles that are so similar that 'the Nintendo DS Lite practically looks like Jonathan Ive built it.' The writer says an Apple and Nintendo merger will 'penetrate the mainstream consumer market with Macintosh computers'. The possible outcome of a merger would be a console based around the Mac Mini. As for whether Apple have the cash to pull it off: 'Cisco was rumoured to be looking at a purchase of Nintendo earlier in the year, so the idea of Nintendo being bought is not outlandish in itself. Apple's market cap is $51.7bn (Nintendo's is $23.1bn)'"
