Treasure hunters are aiming to prove there were tons of loot in the ground in Pennsylvania -- and that the government took it. WSJ: Dennis Parada points to a weedy spot where he believes the Federal Bureau of Investigation dug up nine tons of Civil War-era gold, worth more than $500 million, and made off with it in the middle of the night. The patch of ground halfway up a mountain in western Pennsylvania lies at the heart of the treasure hunter's quest to recover the trove and prove it was snatched from under his nose. The matter is now playing out in federal court.

At 70, he has been chasing the Dents Run gold for more than 40 years. "It's definitely a major coverup," says Parada, who has the mustache of a 19th-century gambler and smokes his cigarettes down to a stub. Tales of lost Civil War-era gold have stirred imaginations for generations though few fortunes have been made. One exception was a pile of more than 700 gold coins minted in the mid-1800s that a farmer unearthed in a Kentucky cornfield earlier this year.

In April 1865, Confederate President Jefferson Davis fled Richmond, Va., with gold that would be worth millions today. Union troops later seized a large portion in Georgia, but that was then stolen at gunpoint. Other stories of lost Confederate gold abound in the South. People across the U.S. have hunted for lost rebel treasure in Virginia, Georgia, Arkansas, Missouri -- and the bottom of Lake Michigan. The searches have inspired novels and films, including "The Good, The Bad and the Ugly," starring Clint Eastwood. Far less attention has been paid to tales of Union gold.

Christine Peterson is a long-time futurist who co-founded the nanotech advocacy group the Foresight Institute in 1986. One of her favorite tasks has been contacting the winners of the institute's annual Feynman Prize in Nanotechnology, but she also coined the term "Open Source software" for that famous promotion strategy meeting in 1998.

Christine took some time to answer questions from Slashdot readers.

During California's Gold Rush, it was often the sellers of pickaxes and shovels who made the most money. In the frenzy to get rich quick from cryptocurrencies, some investors are calling computer chipmakers the modern-day equivalent. From a report: Shares of Nvidia and Advanced Micro Devices have gained at least 14 percent since the beginning of June, spurred in part by about a 10-fold boom from April to June in a market, known as ethereum, for a currency that can be used to buy computing power over the internet. What's the link between ethereum and these Silicon Valley chipmakers? It lies in the really powerful graphics processors, designed to make computer games more realistic, that are also needed to gain access to encrypted digital currencies. Nvidia and AMD have rallied in the last month and a half even as investors have ignored chip stocks leaving the benchmark Philadelphia Stock Exchange Semiconductor Index up about 1 percent. Nvidia has gained 14 percent and AMD rallied 27 percent. While some of that has come from optimism around new products for other markets, analysts are projecting that sales related to cryptocurrencies will result in a spike in revenue for both companies. Even so, investors shouldn't bank on a lasting impact from the cryptocurrency boom, said Stacy Rasgon, an analyst at Sanford C. Bernstein & Co. "This has happened before," Rasgon said. "It lasted about a quarter." [...] Like bitcoin, ethereum is an attempt by an online community to create an economy that doesn't rely on government-backed currencies. Unlike bitcoin, it's focused solely on offering decentralized computing and storage services. Those seeking to use these services -- and speculators looking for a quick profit by creating and then selling ether -- have seized on graphics cards, which excel at performing multiple simple calculations in parallel, as a faster way to claim the blocks of code that act as the currency of the ethereum market. Demand from ethereum miners has created temporary shortages of some of the graphics cards, according to analysts, who cite sold-out products at online retailers. Estimates of additional sales from this demand run as high as $875 million, according to RBC Capital Markets analyst Mitch Steves. That would roughly equal AMD's total sales from graphics chips last year, or half of Nvidia's quarterly sales of those components. But Steves and other analysts are also quick to warn that the market opportunity could fizzle out.

Frequent contributor Bennett Haselton writes: "Hotmail and Yahoo Mail are apparently sharing a secret blacklist of domain names such that any mention of these domains will cause a message to be bounced back to the sender as spam. I found out about this because — surprise! — some of my new proxy site domains ended up on the blacklist. Hotmail and Yahoo are stonewalling, but here's what I've dug up so far — and why you should care."

"Google Knol should allow its writers to publish under a Creative Commons Share Alike license. The preceding sentence may not mean much to you, but if you've ever wanted to cite a Wikipedia article as a source, or simply read a Wikipedia article with some assurance that someone wasn't pulling your leg with some creative editing, or if you've wanted to contribute to Wikipedia but couldn't afford the time unless you received some modest compensation for it, then the addition of this one simple feature to Knol might make all the difference."

Regular contributor Bennett Haselton has written in to say that "The Global Online Freedom Act, introduced last year during a firestorm of controversy over American companies cooperating with totalitarian governments in China and elsewhere, was introduced this month as the Global Online Freedom Act of 2007. When Chris Smith (R-NJ) first introduced the law in 2006, Yahoo was under fire for recently turning over information to Chinese authorities that led to the arrest of a political dissident, Microsoft was attacked for removing pages from MSN Spaces China at the behest of the government, Google was being criticized for removing political sites from search results displayed to China, and Cisco was accused of helping to enable Chinese filtering of the Web. All four corporations testified at a February 2006 House hearing during which Representative Tom Lantos summed up the mood of many of his colleagues by telling the companies, "I do not understand how your corporate leadership sleeps at night." The companies protested that they had no choice but to comply with local Chinese laws, but that they were troubled by their own actions, and -- in a rarity for individual tech companies, much less for a chorus -- they all invited the U.S. government to play a bigger role, while being vague about what the role should be."

GamePolitics brings up a topic well worth discussion, the ad for Hitman currently making the rounds in gaming magazines. Their question is: Sexy or Sexist? From the article: "Her well-kept body lies on a bed of gold satin sheets; her pose is deliberately enticing -- until you realize there is a bullet hole in the middle of her forehead. Then you notice the pool of blood spreading around her pillow. At at first glance, however, the blood seems to be just more accessorizing; it matches her lingerie and high heels. Regardless of your reaction to the photo, one thing is abundantly clear. The ad itself has nothing to do with the game its pimping. Nada. Zippo. Just visit the site for Hitman: Blood Money, and you'll see what I mean." What do you think?

Katamari. Since the launch of the original title, it's been a hat, a cake, and now it's another game. Even then, saying it is another game is a stretch. For the most part the aptly titled We Love Katamari is a mission pack for the original game with an expanded multiplayer component. I don't really care, and anyone who has had the chance to play the original isn't likely to care either. The game is pure PS2 gold, just as much fun as the first foray into star-making. We Love Katamari is pure fan service from the man who doesn't even like games that much anyway. Read on for my impressions of the sequel to the original star-creation-through-rolling simulator.

nazarijo writes "The field of investigative forensics has seen a huge surge in interest lately, with many looking to study it because of shows like CSI or the increasing coverage of computer-related crimes. Some people see a career opportunity there, and are moving toward computer forensics, marrying both law enforcement and investigations with their interest in things digital. Central to this field is the study of data storage and recovery, which requires a deep knowledge of how filesystems work. Brian Carrier's new book File System Forensic Analysis covers this topic with clarity and an uncommon skill." Read on for the rest of Nazario's review.

Okay, here are Alicebot inventor Dr. Richard Wallace's answers to your questions. You're about to enter a world that contains interesting thoughts on A.I., a bit of marijuana advocacy, a courtroom drama, tales of academic politics and infighting, personal ranting, discussion of the nature of mental illness, and comments about the state of American society and the world in general. Yes, all this in one interview so long and strong we had to break it up into three parts to make it fit on our pages. This is an amazing work, well worth reading all the way to the end.

Last week you asked Bradley Kuhn, VP of the Free Software Foundation (FSF) questions about working with RMS, his views on software freedom, and much more. He's answered at length below, on everything from becoming a saint to the "web app loophole," perl, and the next iteration of the GPL.

Last week, you asked Shawn Gordon questions about his venture TheKompany, an outfit which has been (fairly) quietly working on a small flotilla of software for GNU/Linux systems, and some cross-platform applications as well. His responses are below; you might be surprised at a few of them. (And some lucky Debian hacker might even pick up a job.)

Bruce Schneier, well-known security and encryption expert, and author of Applied Cryptography has recently had his newest book published, entitled Secrets & Lies: Digital Security in a Networked World, which explores the world of security as a system. Read the entire review below.

Do you remember the Piranha debacle back in April? Welcome to Part II. Last Tuesday, it was revealed that Microsoft SQL Server 7.0 is shipped with a default password - just like Red Hat's piranha module. Unlike Piranha, SQL Server is very common software for large e-business websites. Unlike Piranha, the vulnerable software has been shipping for months. Unlike Red Hat, Microsoft refuses to take responsibility for their mistake, which, unlike Red Hat's, has resulted in actual documented break-ins, some at high-profile websites. So why haven't you read about it?
