Paolo DF writes "Geocities is closing today. Its advent in 1995 was a sign of the rising 'Internet for everyone' era, when connection speeds were 1,000x or 2,000x slower than is common today. You may love it or hate it, but millions of people had their first contact with a Web presence right here. I know that Geocities is something that most Slashdotters will see as a n00b thing — the Internet was fine before Geocities — but nevertheless I think that some credit is due. Heck, there's even a modified xkcd homepage to mark the occasion." Reader commodore64_love notes a few more tributes around the Web. Last spring we discussed Yahoo's announcment that Geocities would be going away.

There are a handful of features I love about it: [1] Hot-swappable drive bay, with several components that can go in: CD/DVD R/W, extra battery, floppy drive, extra hard drive, memory card reader, etc. The extra battery option is especially appreciated — I can go 4-5 hours on battery power. [2] Docking station / port replicator: I like having my home setup with keyboard, network, and dual screens (a necessity). [3] It runs Linux. OK, I'm a wus, I actually have GRUB command three different OS's: Windows 98 (I have really old embedded software compilers that only run on 98, and yes I have tried every trick in the book to make them run on Linux), Windows XP Pro, and Ubuntu. I'm trying to find a replacement setup that offers the same flexibility and a little better performance. I am open to change as well. So, I ask Slashdot: What is your pick for best developer's laptop under $1,200, considering the features above?"

Brian Eno, or as he is known to many in my office, "God," has released his second iPhone App. A followup to Bloom, this one is called Trope and supposedly creates darker music. You create music by drawing shapes on the iPhone's screen.

After watching the stock market struggle for the past year, financial experts from Wall Street and academia are putting more effort into bringing behavioral modeling into their complex financial calculations. "The risk models proved myopic, they say, because they were too simple-minded. They focused mainly on figures like the expected returns and the default risk of financial instruments. What they didn't sufficiently take into account was human behavior, specifically the potential for widespread panic." Analysts are looking at research from other fields to supplement the hard mathematics of risk assessment. "Financial markets, like online communities, are social networks. Researchers are looking at whether the mechanisms and models being developed to explore collective behavior on the Web can be applied to financial markets." Another avenue they're exploring is how we react to the spread of disease. Jon M. Kleinberg, a computer scientist at Cornell, said, "The hope is to take this understanding of contagion and use it as a perspective on how rapid changes of behavior can spread through complex networks at work in financial markets."

inject_hotmail.com writes "The results are in: it's faster to send your data via an airborne carrier than it is through the pipes. As discussed Tuesday, a company in South Africa called Unlimited IT, frustrated by terribly slow Internet speeds, decided to prove their point by sending an actual homing pigeon with a "data card" strapped to its leg from one of their offices to another while at the same time uploading the same amount of data to the same destination via their ISPs data lines. The media outlet reporting this triumph said that it took the pigeon just over 1 hour to make the 80km/50mile flight, whereas it took over 2 hours to transfer just 4% of that data."

Al writes "MIT neuroscientist Ed Boyden has a column discussing the potential dangers of building super-intelligent machines without building in some sort of motivation or drive. Boyden warns that a very clever AI without a sense of purpose might very well 'realize the impermanence of everything, calculate that the sun will burn out in a few billion years, and decide to play video games for the remainder of its existence.' He also notes that the complexity and uncertainty of the universe could easily overwhelm the decision-making process of this intelligence — a problem that many humans also struggle with. Boyden will give a talk on the subject at the forthcoming Singularity Summit."

A leaked PowerPoint posted at Gizmodo provides a glimpse of what Microsoft's retail shops may look like, noting that you'll even be able to pay to celebrate your birthday there. Some of the stores that were profiled for ideas were Nike, Nokia, Sony, Apple, and AT&T. Microsoft's take on the Genius Bar is the Answers Bar (aka Guru Bar, Windows Bar)."

Hugh Pickens writes "Wired reports that as neural devices become more complicated — and go wireless — some scientists say the risks of 'brain hacking' should be taken seriously. '"Neural devices are innovating at an extremely rapid rate and hold tremendous promise for the future," said computer security expert Tadayoshi Kohno of the University of Washington. "But if we don't start paying attention to security, we're worried that we might find ourselves in five or 10 years saying we've made a big mistake."' For example, the next generation of implantable devices to control prosthetic limbs will likely include wireless controls that allow physicians to remotely adjust settings on the machine. If neural engineers don't build in security features such as encryption and access control, an attacker could hijack the device and take over the robotic limb." Relatedly, several users have written to tell us that science may be closer to the science fiction "mind wipe" than previously thought. Put this all together and I welcome the next step in social networking; letting the cloud drive my limbs around town via a live webcam and then wiping the memory from my brain. Who has MyLimb.com parked and is willing to deal?

Greg George writes "The FDA has determined that Tylenol enhancing pain killers are dangerous enough to potentially be pulled from the market. Drugs including Vicodin, Hydrocodone, Lortab, Maxidone, Norco, Zydone, Tylenol with codeine, Percocet, Endocet, and Darvocet may be permanently banned from the US market, even if the patient has a prescription from a doctor. The problem is the key ingredient — acetaminophen — can easily damage or destroy a patient's liver if more than 2000 mg are used per day. In many cases that means if you take a pain killer and then take two extra strength Tylenol, you may have gone over the maximum dosage per day."

An anonymous reader writes "This experiment graphs the memory usage of Chrome and Firefox 3.5 (along with Safari and Opera) over a series of 150 Web page loads using an automated script. Firefox 3.5 shows the lowest memory usage in all categories, including average memory usage, maximum memory usage, and final memory usage. Chrome uses over 1 GB of memory due to its process architecture. Safari 4 and Opera show memory usage degradation over time, while Chrome and Firefox 3.5 are more reliable in freeing memory to the OS." IE 8 was not included "because the author could not find a way to prevent it from opening a new window on each invocation of the command."

coondoggie writes "News today that the Air Force is investigating signal problems with its latest Global Positioning System satellite is likely to rekindle the flames of a congressional report last month that said the current GPS coverage may not be so ubiquitous in the future. The Air Force stated that routine early orbit checkout procedures determined that the signals from the Lockheed-built GPS IIR-2 (M), which was launched in March, were inconsistent with the performance of other GPS IIR-M satellites. The Air Force said it has identified several parameters in the GPS IIR-20 (M)'s navigation message that can be corrected to bring the satellite into compliance with current GPS Performance Standards."

Wired is running a story inspired by the level of gore in the recent Wolverine game that wonders: how much is too much? It mentions a study we discussed in February which indicated that violence tended to interest gamers less than other characteristics. "... the longer you play a 'twitch' action game, the less you notice the cultural content — the gushing blood, the shrieks of agony. You're too busy focusing on the gameplay. I noticed this with Wolverine. For the first hour, I found the deranged bloodshed both shocking and exciting; it made me feel like I 'was' Logan, the grunting, killing-machine character from Marvel Comics' X-Men universe. But as I became more expert, the cultural shell of the game boiled away. In a sort of staring-into-the-cascading-numbers-of-the-Matrix way, I found myself looking past the visible aspects of the game and savoring the underlying, invisible mechanics of play. ... The game became pure physics and algorithms: Vectors, speed and collision detection. The gore had become mostly irrelevant."

If your child won't sit still at the dentist, the doctor, or the kitchen table, you need the PediSedate Helmet. The device consisting of a colorful headset that connects to a game component or a portable CD player. After a snorkel attachment goes into the child's mouth, the helmet will monitor respiratory function and distribute nitrous oxide or anesthetic gas. The company website states, "The child comfortably becomes sedated while playing with a Nintendo Game Boy system or listening to music. This dramatically improves the hospital or dental experience for the child, parents and healthcare providers."

crazipper writes "Know a Windows power user who is (honestly) good with technology, but hasn't yet warmed to Linux? Tom's Hardware just posted a guide to installing and using Ubuntu 9.04, written specifically for the MS crowd (in other words, it talks about file systems, mount points, app installation, etc). Hopefully, by the end, your 'friend' will realize just how easy Ubuntu can be to use and start down a long path of exploration with a new operating system."

With today's Free Summit broaching the subject of the "dangers" of free, TechDirt has an interesting perusal of why free often can't work without a good business model and why it often gets such a bad reputation. "I tend to wonder if this is really a case of free gone wrong or free done wrong. First, I'm always a bit skeptical of 'free' business models that rely on a 'free' scarcity (such as physical newspapers). While it can work in some cases, it's much more difficult. You're not leveraging an infinite good -- you're putting yourself in a big hole that you have to be able to climb out of. Second, in some ways the model that was set up was a static one where everyone focused on the 'free' part, and no one looked at leapfrogging the others by providing additional value where money could be made. The trick with free is you need to leverage the free part to increase the value of something that is scarce and that you control, which is not easily copied. [...] Still, it's an important point that bears repeating. Free, by itself, is meaningless. Free, with a bad business model, isn't helpful either. The real trick is figuring out how to properly combine free with a good business model, and then you can succeed."
