Discussion2 has been in beta for a few months now on Slashdot. Initially available only to subscribers, it now should be available to anyone willing to login and click the checkbox at the head of every discussion. It is far from complete: IE doesn't work (patches welcome, but since only a quarter of you use it, it's not a huge priority) and performance is lacking (you want a fast computer for larger discussions) but it's already an improvement for most users. Read on for some notes on what we have planned.

Today Apple announced a few expanded open source efforts. First, beginning with Mac OS X 10.4.7, the Darwin/Mac OS X kernel, known as "xnu", is again available as buildable source for the Intel platform, including EFI utilities. Second, iCal Server, Bonjour, and launchd are moving to Apache 2.0 licensing. And finally, Mac OS Forge has been launched, as the successor to OpenDarwin as a conduit for hosting projects such as WebKit that were formerly hosted by the OpenDarwin project's servers, such as WebKit. Mac OS Forge is sponsored by Apple. DarwinPorts has already moved to its own servers. Update: 08/08 01:43 GMT by J : The official Apple announcement is now out. Other fun news: Leopard will ship with Ruby on Rails.

Austin Sarner writes "Phill Ryu's Fake Leopard Screenshot contest which has been attracting a quite a bit of buzz has just ended and the winners have been announced! While there is a bunch of expected stuff in these screenshots, the entrants did not hold back when it came to trying out crazy stuff — and surprisingly, a good amount of them work great. Ranging from new window styles to a complete rethink of a window based work environment, these are sure to make any UI geek excited. The winners received over $1,000 each in prizes, and were obviously motivated to put out some great stuff. The judges included Wil Shipley, the creator of Delicious Library, David Watanabe, who makes NewsFire and Acquisition, as well as numerous other smaller devs."

An anonymous reader writes "As part of his 1680-page book Mac OS X Internals: A Systems Approach, Amit Singh of kernelthread.com wrote a very detailed technical history of Apple's operating systems. Since he had to cut down on the history chapter because of the book's already too-large size, most of this chapter didn't make it to the printed book. Singh has made available the history chapter as a free PDF. The file is 140 pages long, and is generously filled with figures and screenshots. It starts with the internals of the original Apple I and goes through a tour of all operating systems Apple dabbled with, including internals of A/UX, Lisa OS, and such. It even covers details of outside influences like the Xerox Alto, STAR System, Smalltalk, and Sketchpad, and closer to home things like Mach, NeXTStep, and OpenStep."

NoviceW writes to share that there are plenty of interesting articles written about Mac OS X applications for switchers, but not many guides focused on programmers switching from other operating systems. This guide lists a few of the more prominent tools for Mac developers, what other tools can't you do without?

An anonymous reader writes "The MacTech Journal of Macintosh Technology has released MacTech 25, a list of top 25 most influential people in the *Technical* Mac community. According to the magazine 'The MacTech 25 is designed to recognize the technical contributions of developers writers, bloggers, problem-solvers and personalities to the Macintosh technical community.' The people were chosen by popular voting during June. Bios and pictures of the people on the list will be published in the printed MacTech magazine in time for WWDC."

Phillip Ryu writes "As someone in the Macintosh shareware business, as part of my job, I make the daily crawl through MacUpdate to look for the latest and greatest in Mac software. One thing I've been noticing recently is a renaissance of extremely polished and beautiful Mac apps, so I thought I'd share some of these finds with you guys. Without further ado, presenting the top ten most beautiful OS X apps. Hopefully you'll find some new gems in there, even I found a few surprises while compiling this list. Enjoy!"

Philippe writes "F-Script is an integrated set of tools that makes it possible to interactively explore and manipulate Cocoa objects as well as script them using new high-level programming techniques. This new article, Exploring Cocoa with F-Script, shows you how to use some of its most impressive features and demonstrates how it can be a useful addition to your developer toolkit."

InfoWorldMike writes to tell us that InfoWorld's Tom Yager recently had the chance to sit down and chat with Apple about their closing the OS X Kernel. From the article: "The Mac platform is an overflowing basket of raw materials for innovators and creators of all stripes. It's what Steve Jobs would fantasize about if he still worked out of his garage, and you can bet that he'd be livid to find that the vendor locked some portion of his chosen platform behind a gate without a word of notice or explanation."

capt turnpike writes "The modern Apple as we know it -- the good one with open-source Darwin, with Unix-based OS X, and so on -- was mainly the creation of NeXT: Steve Jobs, Avie Tevanian and Jon Rubenstein. What's going to happen to Apple once this troika leaves? eWEEK.com looks at the orderly transition out of Jon and Avie and asks whether things could go as smoothly should Jobs need to retire." From the article: "At some companies, such a loss of leadership could leave the company with a power vacuum or a lack of direction. However, Apple seems to be conscious that no single person--except, perhaps, CEO Steve Jobs himself--is irreplaceable, and that new talent can always be groomed for the future."

MacHore writes "0xFE has an excellent tutorial on Mach-O, which is the file format used by OS X executable files and libraries. It goes into great detail about how Mach-O works, and explains what OS X actually does when it loads and runs an application. Subtopics include Universal Binaries, The Dynamic Linker, Using otool, and other goodies."

Moby Cock writes "The recent display of iLife '06 at Macworld showed that the suite has a very fine integration with .Mac, Apple's subscription-based web portal. In a recent post to his blog on ZDNet, Dan Farber argues that a .Mac subscription ought to be included with the purchase of an Apple computer. There is no doubt that web portals are huge revenue engines, could Apple be missing an opportunity here?"

Firmafest writes "The Register is running a story about Sun and Apple almost merging on three separate occasions. The information was revealed at a Computer History Museum event, where Sun's four co-founders spoke about the history of the Sun company. Bill Joy said that the two comp anies almost teamed on three different projects, including sharing a user interface and the SPARC architecture." From the article: "'As far as I know we also almost bought Apple once,' Joy said. 'We almost merged with Apple two other times.' Many Silicon Valley observers have long seen links between Sun and Apple. Both companies make slick, pricey hardware and are counter-punchers in their respective markets. They also have charismatic CEO figures and strong anti-Microsoft streaks"
