I get a lot of mail from obviously unbalanced people. Enough in fact, that I've often wondered if there was a institution that allowed their patients to only read Slashdot. We've even had a few visits from some questionable individuals. A man who tried to bribe me with a car if I let him "reverse engineer" Rob Malda's Life comes to mind. He insisted on Rob being present for the process and couldn't explain to me what it entailed, so I suggested he leave. The personal visits are rare, however, compared to the amount of mail I get. Here are a few of my favorites; let's hope these people have started to take their medication. Read below and don't be worried if you don't understand all of it.

Engadget is reporting that a new pyramid-shaped city of the future, dubbed a "Ziggurat," is being touted by Dubai-based environmental design company, Timelinks. Claiming that their design allows for an almost self-sufficient energy footprint and, obviously, economy of space, the real trick would be getting 1.1 million people to live in such close proximity. "Martijn Kramer, managing director of The International Institute for the Urban Environment told WAN: 'As a general reaction the Ziggurat Project is viable from a technical point of view. However reflecting from a more sustainable holistic approach we do wonder if the food supply and waste system are taken care for, as the concept seems rather based upon carbon neutrality and energy saving.' Kramer's initial reaction to 'Ziggurat' also raises a very important issue: are people willing to live in a mega building of 2.3 sq km? Will the thought of living in a machine comfort people?"

bLanark writes "Some time ago, most electronics were soldered with old-fashioned lead solder, which has been tried and tested for decades. In 2006, the EU banned lead in solder, and so most manufacturers switched to a lead-free solder. Most made the switch in advance, I guess due to shelf-life of products and ironing out problems working with the new material. Lead is added to solder as it melts at low temperature, but also, it prevents the solder from growing 'whiskers' — crystalline limbs of metal. The effect of whiskers on soldered equipment would include random short-circuits and strange RF-effects. Whiskers can grow fairly quickly and become quite long. Robert Cringley wrote this up this some time ago, but it seems that the world has not been taking notice. I guess cars (probably around 30 processors in a modern car) and almost every appliance would be liable to fail sooner than expected due to tin whiskers. Note that accelerated life-expectancy tests can't simulate the passing of time for whiskers to grow. I've googled, and there is plenty of research into the effects of tin whiskers. I should point out that the Wikipedia page linked to above states that tin whisker problems 'are negligible in modern alloys,' but can we trust Wikipedia? So: was the tin whisker problem overhyped, was it an initial problem that has been solved in the few years since lead-free solder came into use, or is it affecting anyone already?"

Iddo Genuth writes "Precisely at 7:53PM EST, the "Phoenix Mars Lander" touched-down on the desert-like surface of Mars. Since its launch on August 4th, 2007, the spacecraft has covered more than 680,752,512 kilometers, traveling at average speeds of around 120,000 km/hr. Upon arriving at its destination, the Phoenix will begin its exploration of our intriguing neighbor planet, in a mission to help astronomers resolve at least some of the many questions regarding Mars. The key question remains: can the Red Planet support some form of life?" Hella grats to our nerd brethren — you looked great on the Science channel. Yes I'm watching this live. Can't wait to see what happens next.

Raver32 points out an article in the Victoria Times Colonist about an interesting advance in robotic surgery: "Calgary doctors have made surgical history, using a robot to remove a brain tumor from a 21-year-old woman. Doctors used remote controls and an imaging screen, similar to a video game, to guide the two-armed robot through Paige Nickason's brain during the nine-hour surgery Monday. Surgical instruments acting as the hands of the robot — called NeuroArm — provided surgeons with the tools needed to successfully remove the egg-shaped tumor."

Betsy Carroll writes "The Stanford research group on virtual teams discusses how the appearance of one's avatar in virtual worlds has an effect on real life behavior in an NPR interview. The researcher they speak with focuses on the concept of vicarious reinforcement for changing behavior. They also talk a bit about identity issues surrounding the avatar and the 'real' physical self."

Gallenod writes "The Denver Post is reporting that the U.S. 10th Circuit Court of Appeals has upheld the decision of a Federal judge who threw out and reversed a jury decision in favor of a patent infringement claim and ordered the plaintiff's lawyers to pay the defendants' court costs. U.S. District Senior Judge Richard P. Matsch sanctioned the plaintiff's attorneys for 'cavalier and abusive' misconduct and for having a 'what can I get away with?' attitude during a 13-day patent infringement trial in Denver. With the Appeals Court in agreement, could this case be the 'shot heard round the world' in the revolution against patent trolls?"

inghamb87 writes "The way water striders walk on water was discovered years ago. The insect uses its long legs to help evenly distribute its tiny body weight. The weight is distributed over a large area so that the fragile skin formed by surface tension supports the bug on the water. However, the ability of water striders to jump onto water without sinking has baffled scientists, until now." If nothing less, you need to see the picture: it's awesome.

Gailin writes "Google has announced and given some examples of their new Flash based ads. They seem to vary from average size to full screen-width Flash advertisements, with some interactive abilities. 'Gadget ads can incorporate real-time data feeds, images, video and much more in a single creative unit and can be developed using Flash, HTML or a combination of both. Designed to act more like content than a typical ad, they run on the Google(TM) content network, competing alongside text, image and video ads for placement. They support both cost-per-click and cost-per-impression pricing models, and offer a variety of contextual, site, geographic and demographic targeting options to ensure the ads reach relevant users with precision and scale.'"

Meshach writes "There is an interesting story at CBC which claims that Google loses one billion dollars per year to fraudulent ad clicks. The article contains an interesting description how how the company determines if a click is false. 'The company explained that it determines which clicks are invalid through a three-stage system. Most of the illegitimate clicks are automatically detected analyzed and filtered out in the first stage ... The second part uses automatic and manual analysis of the AdSense network to weed out false clicks before they are logged to an advertiser's account.'"

An anonymous reader writes "NBC's recent withdrawal from the iTunes store leaves the millions of Apple's customers who have Macs or iPods without a legitimate way to purchase and watch NBC's content. Online media stores such as iTunes, Amazon and Walmart have never been able to compete with the pirates on price, or freedom and flexibility — as the content they sell is typically wrapped in restrictive DRM. The one advantage that legal purchase offered was ease of use. CNET looks into the issue, and discovers that with mature open-source media players such as Miro supporting BitTorrent RSS feeds, it is actually trivially easy for users to subscribe to their favorite shows. Want to wake up to the latest episode of The Colbert Report, Top Gear or any of hundreds of TV shows automatically downloaded and waiting for you? CNET offers an easy three step guide."
