joabj writes "Expanding beyond math and the physical sciences, Khan Academy has added a set of computer science courses to its popular collection of learn-at-home instructional videos. For the project, Khan tapped jQuery creator John Resig, who chose JavaScript as the first language to teach students. The initial set of tutorials cover drawing, programming basics, animation and user interaction."

Cloud

+ - Microsoft brings Linux to its Azure cloud service->

Submitted by
joabj
joabj writes "Well, after years of fighting Linux, Microsoft will soon start selling access to Linux distributions, at least in the form of virtual machine images that can be run in its cloud. Starting Thursday, the company will officially offer Ubuntu, SUSE and CentOS virtual images on its Azure cloud platform, initially as a technology preview. The official blog announcement can't bring itself to mention the distributions by name, though a fact sheet (in Word) spells out the specific versions being deployed. Other new open source technologies on Azure include MongoDB, Solr, CouchDb, PHP, Python. Perhaps Amazon Web Services, which has long offered open source technologies, is proving to be too big of a competitive threat?"

+ - Researcher runs IP network over xylophones ->

Submitted by
joabj
joabj writes "Following up on experiments of running Internet Protocol(IP)-based networks with carrier pigeons or bongos, UofC grad student R. Stuart Geiger has demonstrated that it is possible to transmit simple ping requests across two computers using people playing xylophones. Throughput is roughly 1 baud, when the participants don't make any mistakes, or get bored and wander off. The OSI encapsulated model of networking makes this project doable, allowing humans to be inserted at Layer 1, the physical layer. Vint Cerf wasn't kidding when he used to say, "IP on Everything.""

+ - Internet group seeks wider input for BIND 10->

Submitted by
joabj
joabj writes "ISC is seeking some open source magic for the next version of the widely used BIND. Although the BIND is already open source, most of the work thus far done on the DNS server software has come from contractors, the government and Unix vendors. "The goal is to move away from having BIND a heavily sponsored corporate product," said BIND 10 manager Shane Kerr. Kerr is hoping that more eyes will equal fewer bugs, and that more users will go ahead and implement the features they've been requesting themselves. BIND 10, due by the end of the year, features a new modular architecture, one designed circumvent many of the security woes that have bedeviled BIND 9."

+ - 'Dead Media' Never Really Die->

Submitted by joabj
joabj (91819) writes "A streaming music service was available a 100 years ago by telephone, through the Teleharmonium. A primitive version of Photoshopping was possible with Black Mirrors in the 18th century. While technologies and media platforms go obsolete at an ever more rapid pace, the ideas they engender never really die. They get absorbed by newer technologies, or are at least preserved by hobbyists (carrier pigeons) or niche markets (Morse Code), argued NYU New York University postdoctoral researcher Finn Brunton at the USENIX conference. Myself, I'm waiting for an update to the visual cortex-stimulating Dream Machines of the 1960s."

So what will Oracle do with the domain name, which is the 12th oldest .com site on the Internet? Domain brokers speculate Oracle could sell it for $1 million or more, if it chose to do so."

When Smart People Make Bad Employees 491

Posted by samzenpus
from the boss's-favorite dept.
theodp writes "Writing for Forbes, CS-grad-turned-big-time-VC Ben Horowitz gives three examples of how the smartest people in a company can also be the worst employees: 1. The Heretic, who convincingly builds a case that the company is hopeless and run by a bunch of morons; 2. The Flake, who is brilliant but totally unreliable; 3. The Jerk, who is so belligerent in his communication style that people just stop talking when he is in the room. So, can an employee who fits one of these poisonous descriptions, but nonetheless can make a massive positive contribution to a company, ever be tolerated? Quoting John Madden's take on Terrell Owens, Horowitz gives a cautious yes: 'If you hold the bus for everyone on the team, then you'll be so late that you'll miss the game, so you can't do that. The bus must leave on time. However, sometimes you'll have a player that's so good that you hold the bus for him, but only him.' Ever work with a person who's so good that he/she gets his/her own set of rules? Ever been that person yourself?"

Pac-Man's Ghost Behavior Algorithms 194

Posted by Soulskill
from the i-hate-the-pink-one dept.
An anonymous reader writes "This article has a very interesting description of the algorithms behind the ghosts in Pac-Man. I had no idea about most of this information, but that's probably because it's difficult to study the ghosts when I die every 30 seconds. Quoting: 'The ghosts are always in one of three possible modes: Chase, Scatter, or Frightened. The "normal" mode with the ghosts pursuing Pac-Man is Chase, and this is the one that they spend most of their time in. While in Chase mode, all of the ghosts use Pac-Man's position as a factor in selecting their target tile, though it is more significant to some ghosts than others. In Scatter mode, each ghost has a fixed target tile, each of which is located just outside a different corner of the maze. This causes the four ghosts to disperse to the corners whenever they are in this mode. Frightened mode is unique because the ghosts do not have a specific target tile while in this mode. Instead, they pseudorandomly decide which turns to make at every intersection.'"
Microsoft

+ - Microsoft invests in open source software company->

Submitted by joabj
joabj (91819) writes "In what may be its first investment in an open source software company, Microsoft has quietly invested in TurboHercules, which maintains the Hercules open source IBM mainframe emulator. Perhaps the potential for purloining customers from the juicy mainframe market outstrips any misgivings Microsoft may have about open source. You might remember TurboHercules: In March, it filed an antitrust complaint with the EU over IBM's tying of its mainframe OSes with its hardware."

Student Googles Himself, Finds He's Accused of Murder 184

Posted by samzenpus
from the be-careful-what-you-search-for dept.
University of Florida student Zachary Garcia was more than a little surprised to find out he was wanted for murder after Googling his name. It turns out the police were looking for a different man but had mistakenly used Garcia's photo. From the article: "Investigators originally released a driver's license photo of Zachary Garcia — spelled with an 'A' — but it was Zachery Garcia — spelled with an 'E'— who was charged in connection with the crime."
