I’m lazy and tired tonight so i’m falling back on a link list.
No, not the data structure type, but just a list of links to interesting articles for the day. BTW, if you haven’t seen the Stanford Blinky Pointer animation that explains pointers, check it out, if nothing else you’ll enjoy the ‘magic wand of dereferencing’. Anyway, the wife kept me up most of the night and now I can hardly think straight, so before I hit the hay, here’s a few links to articles I found interesting today:
Vanderbilt University scientists say you’re brain isn’t wired to multi-task two decision making tasks simultaneously. You can thank the region of the brain for its ‘dual task interference’ phenomenon that postpones one cognitive task until another is completed. [Links to Chemistry.org]
Nature.com informs us that while barnacles can slow down ships, which costs you and the transporter money, a graduate student from Cornell has a solution. It’s a polymer that can be sprayed to a surface exposed to water and will prevent growth or sundry creatures from attaching themselves. Other products were produced before to do this but proved so toxic to the environment they were banned. This one looks promising and the Brine Shrimp are simply raving about it.
From physorg.com is an article on a new brake light system for cars. Some (or perhaps a lot) of rear end car collisions may be preventable using technology instead of keeping to the 2 second rule. During a braking scenario, drivers perceive the time separation between themselves and a vehicle they’re following based on the size of the image of the leading vehicle on the driver’s retina. They hypothesized that if it were possible to exaggerate how quickly the retinal image expanded, drivers might brake sooner in potential crash situations. A preliminary study using a driving simulator confirmed that they did. The next challenge was to find an application for this knowledge.
There solution is to make the brake lights *appear* to grow in size, fooling the brain since the retinal image increases in size. In tests, this got people to brake 100-300 msec sooner!
So does this mean the tailgaters can get closer now?
The folks at Evil Mad Scientists take you through the teardown process of a nixie tube. My gawd, it’s been about 15 years since I last played with electron tubes. They were so much easier to work with than software, it’s software that has added more gray to my head than even the wife.
