the linux geek writes "InfoWorld has an article informing us that an early beta of Mac OS X 10.5 has been leaked. This appears to be the same build Steve Jobs previewed at WWDC, and contains most of the new features, including Time Machine and Spaces." From the article: "Attendees at last week's Worldwide Developers Conference (WWDC) received copies of the beta ware and had to sign legally binding agreements not to let Leopard stray onto file-sharing networks. Perhaps someone didn't read the not-so-fine print? MacUser reports that this version of Leopard is indeed legit, unlike a fake one that was reportedly making its rounds last week. The version of Leopard available on BitTorrent is 4.3GB, containing 93 files."

RX8 writes "A Digital Trends article suggests that Apple's Leopard agenda is to get Windows users to use Apple hardware then convert them to the Apple camp and that Apple will also be directly targeting Dell by offering a better experience when it comes to media and related tasks. Lastly, they suggest that Steve Jobs held back on showing more Leopard features so people would not get too excited and stop buying in 2006. 'If you get too excited about what is supposed to be an incredibly amazing product you simply won't buy a new Apple this year.'"

Read on for some of the most interesting comments and exchanges on a handful of yesterday's Slashdot posts (on the age of the Universe, virtual desktops in OS X, trick photography on the Reuters wire, and AOL's latest privacy gaffe) in today's Backslash summary.

William Henderson writes "That's right, if you haven't read it for yourself yet, Objective-C '2.0' now supports garbage collection. I foresee a great, huge, gigantic debate about to ensue, and a lot of java-heads sparking 'I told you so'. Why not start it here on slashdot?"

haym37 writes "Of the many announcements yet to come at WWDC, the first is the announcement of the Mac Pro. The Mac Pro contains two Intel Xeons, up to 3 GHz, and is supposed to be 1.6x to 2.1x the speed of the PowerMac G5 quad. It can hold up to 2 TB of internal storage and up to 16 GB of memory. The graphics card can be up to a Radeon x1900 or an FX4500. The case will be the same as the PowerMac." MacRumors.com is providing running coverage from the floor (Note: "[U]pdates will be automatically inserted at the top of the updates section. Do not reload manually."), including another announcement that OS X will include virtual desktops. What a great idea!

pdscomp writes "VMware has just announced at today's Apple WWDC 2006 Conference that they are developing a port of VMware to Mac OS X. People interested in beta testing the product later this year can visit this link to sign up for the public test. It will be interesting to see how things play out between VMware and Parallels. Will Microsoft bother porting Virtual PC now that there will be two other Intel OS X virtualization solutions available? Now all we need is to get Mac OS X running under Xen."

Vexorian writes "Two NASA websites were hacked today by a group of Chilean activist hackers. The reason was to protest against the war on Lebanon. The mirror of the defaced site contains an image of an injured child and claims that the sites were running MacOSX."

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?

Wednesday's press-release-borne message from security firm Sophos that the best way for Windows users to compute untroubled (or less troubled) by malware is to switch to Mac OS X drew more than 500 comments; read on for the Backslash summary of the conversation.

Max Fomitchev writes "Looks like Apple is going to reveal its new cool and fast Mac OS code-named 'Leopard' in the upcoming World Developer's Conference in August. Good news for Apple! And terrible news for Microsoft. If 'Leopard' is really what it claims to be, i.e. fast and efficient, in sharp contrast to slow and resource hungry Windows Vista, we certainly would see Apple's remarkable market share gain next year."

Mindpicnic writes "The recent switch of two lifelong Mac nerds to Ubuntu hasn't escaped Tim O'Reilly's radar. He cites Jason Kottke: 'If I were Apple, I'd be worried about this. Two lifelong Mac fans are switching away from Macs to PCs running Ubuntu Linux: first it was Mark Pilgrim and now Cory Doctorow. Nerds are a small demographic, but they can also be the canary in the coal mine with stuff like this.'"

You submitted questions for Håkon Wium Lie on June 20. Today we have his answers, not only to the (+5 moderated) questions we sent him, but to a bunch of others he thought would also be interesting to answer.

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."

jglidell writes "The OS X kernel has been in the news alot this past year, whether it's why its slow, Mach/micro-kernel makes it bad, it's going closed source and what not. Amit Singh has put up a new presentation on the innards of OS X. It does a pretty good job of summing up the OS X kernel architecture, and has some pretty detailed diagrams... for instance they show that there are so many process/threads layers in OS X. So if you are in the mood for doing some OS studying then head over."

Cjattwood writes "Mac OS rumors has an article describing a possible implementation of a Bittorrent client into Mac OS X 10.5 "Leopard", including a unique sharing reward system where the user can share bandwidth and get rewards, such as credit in the iTunes store."

Udo Schmitz writes "Apples Filesystem Development Manager, Chris Emura, is looking into porting Sun Microsystems' file system ZFS to OS X. At least this is what Sun's Eric Kustarz states on the ZFS mailing list. Is this a glimpse of hope for all those of us who think HFS+ isn't up to par for a 21st century OS? Next thing you know and they'll rewrite the Finder ..."

Bill writes "MSNBC reports that the combination of Apple's growing market share and their recent switch to x86 processors has made Mac OS X a new target for viruses. Unfortunately, it seems that many Mac users are in denial. '[Computer security expert Tom] Ferris said he warned Apple of the vulnerabilities in January and February and that the company has yet to patch the holes, prompting him to compare the Cupertino-based computer maker to Microsoft three years ago, when the world's largest software company was criticized for being slow to respond to weaknesses in its products.'"

mcho writes "Unlike other speculators, who get no spam, Robert X. Cringely offers an intriguing reason behind Apple's recent strategy of Boot Camp. From the article: 'I believe that Apple will offer Windows Vista as an option for those big customers who demand it, but I also believe that Apple will offer in OS X 10.5 the ability to run native Windows XP applications with no copy of XP installed on the machine at all. This will be accomplished not by using compatibility middleware like Wine, but rather by Apple implementing the Windows API directly in OS X 10.5.'
