Ask Slashdot: Good Technology Conferences To Attend?
I like NANOG (http://www.nanog.org) for network engineering topics. It's geared towards large service provider networks, not so much enterprise/small business, but still quite informative and great for networking of the social variety as well.
A Look At the Firepick Delta Circuit Board Assembler (Video)
This project appears to have computer vision for parts alignment, which is a HUGE deal for a pick-and-place. You need your machine to know if a component is oriented improperly in the reel, and to provide positive feedback on board position by referencing fiducials for accurate placement of fine-pitch components. Other pick-and-place projects I've seen in the past have been just standard 3-axis CNC gantries with a vacuum pickup, the addition of CV means it potentially can truly compete with the high-cost units.
Two South African Cancer Patients Receive 3D Printed Titanium Jaw Implants
My most recent energy-saving bulbs last ...
I've bought a number of Feit Electric CFLs from Costco, and get at least a few years of regular use out of them. However, whenever I've bought the same brand from various local hardware stores (both mom-n-pop and big brand stores) I've had them fail within a few months. I'm not sure what's up with that, but that's my experience. I have yet to try any LED bulbs due to the up-front cost and the long life I'm getting out of my CFLs, and I have no use cases where dimming is necessary.
Ode To Sound Blaster: Are Discrete Audio Cards Still Worth the Investment?
At work I have a HiFiMeDIY Sabre Tiny USB DAC ($30) as my work laptop's internal audio is full of noise (hissing that changes with system activity).
At home, my gaming machine uses its onboard audio interface, but sends digital audio out via SP/DIF to my home theater receiver for its DAC and amplifier.
I even have an external sound interface for ham radio use, a Tigertronics SignaLink USB that's just an external ADC/DAC with some filtering and isolation which interfaces with my radio for digital modes (such as PSK31 or RTTY).
Interviews: Ask Andrew "bunnie" Huang About Hardware and Hacking
His book, Hacking the Xbox, is now available for free: http://www.nostarch.com/xboxfr...
The chapter on the methods he used to actually bypass the system's boot security was fascinating.
Security DVR + iNet + X10 = Easy Home Automation (Video)
I saw this at Maker Faire, he's using an on-screen display generator to produce menus and output that you feed into a video input channel on the DVR, and it intercepts the DVR's RS-485 bus (used for pan-tilt-zoom control of cameras) to receive command input from the user. Pan down is parsed as next menu item down, pan right is "enter", etc. It's quite nifty. The menus are set up for individual X-10 or other commands, and you can even set up multi-event macros.

Judge Says You Can Warn Others About Speed Traps
Make sure to read the CVC definition of a speed trap before you assume what you consider a "speed trap" is illegal:
Ask Slashdot: Best Headphones, Earbuds, Earphones?
I have a pair of Koss headphones that are just like you describe, I'm a big fan of them. They are quite comfortable and sound pretty good too.

Remote-Controlled Planes Used For Wildlife Conservation
They're using the DIYDrones ArduPilot, the image in the article shows the ArduPilot Mission Planner software. For a few hundred dollars you can turn an RC aircraft into an autonomous craft, it's a very nifty project.
With regards to beer, I prefer it to be:
I too am a fan of root beer. A friend makes his own, but not from the pre-made syrups. He steeps sassafras root (carcinogens be damned!), mint leaves, vanilla, and other tasty ingredients, then filters and carbonates it and lets it rest for a while. My wife refers to it as lick-a-tree root beer due to the low sugar content, but I enjoy the taste.
FPS Games That Need a Remake
Homeworld was a space-based RTS, not a flight sim. It was fun though.
Freespace 2 has a lot of community work going into it to update the models and effects. There are also several total conversion projects including a Babylon 5 conversion and a Wing Commander conversion. (Oh, how I miss Wing Commander...
How To Get a Game-Obsessed Teenager Into Coding?
What about something like Robocode, that requires programming to compete in the game?
Hot Or Not — 3D TV
Unless you can develop a backlight that can switch polarizations easily and quickly (or a filter over the TV that can switch back and forth), how would the TV produce alternating polarized images? It's easy at a movie theater, you just have two projectors, each with their own polarizer. It could be done with a projection type TV (such as with a polarized color wheel for DLPs), but I'm not sure how it would be accomplished with a direct-view LCD or plasma TV.
Hot Or Not — 3D TV
When watching 3D movies, I tend to go cross-eyed and get a headache very quickly. I think it's because everything I'm seeing is on the same focal plane, but my eyes attempt to adjust for parallax based on different apparent distances of objects. I had to walk out of Avatar 3D after about 10 minutes, I just could not watch it like that. Does anyone else experience this?
Microsoft Releases Prototype of Research OS "Barrelfish"
In California, home of the rolling stop, we also have many double right turn lanes at the end of freeway offramps, where the the two rightmost lanes are for right turns. Californians have come to behave (erroneously) as if a right on red is legal from either lane. Rather than educate the drivers, cities have begun installing NO RIGHT ON RED signage at these intersections.
Where is such a turn prohibited in the vehicle code?
21453(b): Except when a sign is in place prohibiting a turn, a driver, after stopping as required by subdivision (a), facing a steady circular red signal, may turn right, or turn left from a one-way street onto a one-way street. A driver making that turn shall yield the right-of-way to pedestrians lawfully within an adjacent crosswalk and to any vehicle that has approached or is approaching so closely as to constitute an immediate hazard to the driver, and shall continue to yield the right-of-way to that vehicle until the driver can proceed with reasonable safety.
22100(a)(3): Upon a highway having an additional lane or lanes marked for a right turn by appropriate signs or markings, the driver of a vehicle may turn right from any lane designated and marked for that turning movement.
You come to the light at either of the right-turn lanes, you stop, and if it is safe to do so you may make a right turn.
5 Powerline Networking Devices Reviewed
I use something similar to run speaker wire to my rear speakers. I have it run up the side and across the top of a doorframe to the corner of the room, then it goes up to the ceiling, and along the ceiling/wall edge to the speakers. It blends in fairly well.
You can also pull up the edge of your carpeting and stuff cable under it (along the walls works well, but I wouldn't do that across a hallway or doorway), or remove your baseboards, cut a cable path into the drywall, run cable through it, and replace the baseboards.
