Yellow Box Redux?

So we’re just starting to pack for WWDC now, and as our last post for a while probably (since anything that’s actually got us excited next week will probably be under heavy NDA) we’ll just go out on a limb with a rather out there but we think logical prediction for Monday’s keynote. 

See, our Impeccable Sources™ in the Apple world have been dropping hints that there’s something Big And Unexpected up for announcement, which is not directly related to the iPhone in particular nor hardware of any kind in general. If they’re not just teasing to wind up our curiosity to fever pitch — which is hardly inconceivable, we grant you, in which case after the keynote feel free to laugh your head off at how well that worked for them — what could it be? This .mac to .me reworking thing? Naah, we don’t see that qualifying as either particularly Big or in the slightest Unexpected.

Well, after pondering it, we think we just might have an idea. You’ve all heard about this “Snow Leopard” thing, no doubt. Well, we believe there actually is a “Snow Leopard” project, which quite likely will be revealed on Monday, but it’s not going to be 10.6 like most everyone is assuming, because that would be a different cat — there’s no way Apple would not rebrand the OS name for a full point release. For the same marketing-related reasons, we’ll proceed to assume that this code name is not disinformation of any kind. So there’s something bubbling and simmering in Apple’s labs that’s recognizably “Leopard”, but distinctly different enough from the shipping Mac OS X 10.5 to merit a separate yet connected brand.

Right then, the next wide assumption is that the dropping of “Mac” from the “OS X Leopard” posters in Moscone implies that there’s going to be a non-Mac OS X Leopard for generic PCs, and that would be Snow Leopard. We’re pretty sure we can dismiss that one as well. Apple’s revenue numbers just don’t make that idea work, however you slice it. And when even all the PC magazines universally agree that Mac laptops are the best for running Vista, there appears to be no reason to defocus from shipping machines.

So what, then, is “Snow Leopard”? Well, to answer that, let us put on our thinking caps. What is the one feature that developers were most upset about losing in OS X — before it was actually named OS X, in fact? The feature that Apple has a clear and compelling reason to bring back now, in order to further increase the pool of developers familiar with Mac and iPhone programming concepts? The feature that did, indeed, actually ship from Apple on the Rhapsody DR1/Intel Developer CDs? The feature which if released on Monday would be a perfect fit for the “Snow Leopard” moniker? Well, here’s what we say it is:

Apple Rhapsody Yellow Box for Windows

Yep, that’s our call: “Snow Leopard” is the return of Yellow Box. Except that the point of it this time around is not only, or even mostly, to allow Mac Cocoa programmers to deliver Windows applications — although it’s pretty likely that will be supported — but to let Windows users who for whatever reason can’t get a Mac of their own to develop iPhone programs using the same Cocoa-written toolchain that supports iPhone development on real Macs.

You heard it here first, folks!

POST-KEYNOTE UPDATE:

Hmmmmm. It appears that the only non-NDA’d information y’all who aren’t here is gettin’ is that yes, there actually is a “Snow Leopard” project, His Jobness stated, and us here is gonna hear all about it after lunch, in an NDA’d session. So it’s not completely impossible yet that we’re on to something here — but the smart money is that probably, contrary to all previous practice, the rumours about “Snow Leopard” being simply a rather boring 10.6 version are indeed correct, and the Big Important Thing that had been hinted at was indeed Mobile Me, aka “Exchange that doesn’t suck”. Ah well.

We’re quite sure there’ll be no shortage of people willing to violate their NDAs so you won’t have to wait until tomorrow even to find out the exact specs of “Snow Leopard” somewhere else — but as far as this particular legally correct NDA-respecting space goes, we’ll just have to leave the discussion at “probably a bad guess but we’ll know for sure in an hour.” Ah well. Can’t always have everything you want, and we’re pretty happy with how the iPhone 3G turned out!

POST-WWDC UPDATE:

Well, although this speculation turned out to be completely wrong, we actually were not completely off-base in identifying Apple’s interests and goals we figure; we just weren’t thinking outside the box enough in figuring that resurrecting Yellow Box was how to go about it. See this post for what we’re thinking now!

Free T-shirts @ WWDC!

Yep, start the week off right with a free T-shirt from FastMac:

San Francisco, CA - FastMac today announced 5 T-shirt designs to commemorate WWDC 2008 & Apple’s imminent launch of a new iPhone. The T-shirts use iPhone inspired themes to celebrate the world’s most advanced mobile platform: OS X iPhone 2.0. The T-shirts will be given away for free outside the Moscone Convention Center in San Francisco between 12 AM and 6 AM on June 9th. 

Well, that’s one less day I need to pack a shirt for!

WWDC on your iPhone!

If you’re going to be at WWDC — and hey, even if you’re not, there’s other stuff there too — you should be aware of www.iviewr.com, which “provides a unique service to users of Apple’s mobile devices. Users can view handy snapshots of popular destinations and events around the globe.” In this case, it’s WWDC!

iPhone and iPod touch-wielding visitors to next week’s Apple Worldwide Developers Conference (WWDC) in San Francisco can enhance their visit to the show with a handy guide made available by iViewr.com.

A website for iPeople who are going places, www.iViewr.com has introduced its latest event guide aimed at the legion of developers making the pilgrimage to the conference.

Completely free to access, this handy ‘Pod SnapShot’ has the look and feel of a native iPhone application and provides details of all aspects of the show - from Conference Schedules, Lab and Session details, Travel directions, Disabled access, Moscone Center facilities, after hours events and more.

“Like the previous event guides we’ve made available, iViewr provides visitors to the Conference with all of the important information especially formatted for display on their iPhones or iPods” said Rod Cambridge, founder of iViewr. “If you have one of these devices, there’s simply no more need to be carrying around a jumble of papers, map and leaflets when a guide like ours is available.”

Well, hard to argue with that; my Springboarded bookmark of their site has certainly replaced the 2-per-day printouts that I made last year to try and keep track of sessions. An excellent service, and probably worth checking out whatever else is there as well.

SquirrelFish!

What is a “squirrelfish”? Why, this is a squirrelfish!

I’m sure there must be an interesting story as to where that came from, but “SquirrelFish” is the code name of the new WebKit JavaScript interpreter that was just announced. A 1.6 performance improvement over WebKit 3.1, they claim, and over four-fold from WebKit 3.0. And, no doubt, whatever performance improvements are in the WebKit nightlies now will make it to the iPhone sooner or later … and probably sooner.

There’s a good bit of background info in the announcement post which is probably worth reading if you’re the sort that has any more interest in interpreter implementation than the absolute minimum you could squeeze through your required degree courses without avoiding. And even if you are one of those sorts, there’s some pointers to contemporary introductory material that’s probably worth a gander just for general breadth of knowledge. So here’s the money quotes there:

SquirrelFish is a register-based, direct-threaded, high-level bytecode engine, with a sliding register window calling convention. It lazily generates bytecodes from a syntax tree, using a simple one-pass compiler with built-in copy propagation.

SquirrelFish owes a lot of its design to some of the latest research in the field of efficient virtual machines, including research done by Professor M. Anton Ertl, et al, Professor David Gregg, et al, and the developers of the Lua programming language.

Some great introductory reading on these topics includes:

Read and enjoy!

All about C99

Yep, we’re always on the cutting edge of the latest news and breaking developments here Under The Bridge, so today we’re going to talk about — wait for it — the C99 standard for the C programming language!

Um, you may understandably be thinking, how does ISO/IEC 9899:1999, published 1999-12-01, qualify as a breaking development now exactly?

Well, grasshopper, it’s a breaking development because it has recently come to public light on the xcode-users list that recent versions of Xcode have changed the default C language dialect to C99, apparently deciding that GCC 4.0’s C99 feature support can now be deemed complete. So that means that if you’re using Xcode to target Any New Device Currently Under NDA™, it would behoove you to clue into just what’s changed and different in this “new” version of C. And, conveniently, this fine fellow David Hoerl has put together a reading list for us:

It took a while but I finally did uncover a really good series of articles written by Randy Meyers for the C/C++ Users Journal several years ago. Posting these here in case you have been thinking of doing the same in the near future:

The New C: It All Began with FORTRAN

The New C: Integers, Part 1

The New C: Integers, Part 2

The New C: Integers, Part 3

And if you’re not satisfied by all that, there is also available The New C Standard: An Economic and Cultural Commentary, a 1615-page book which annotates the entire standard, sentence by sentence. And it’s completely free, as Addison-Wesley backed out of publishing it once they got a look at it. Probably not a wholly indefensible decision on their part, as it’s not exactly what most people would consider a gripping page-turner, but it is remarkably exhaustive in its coverage.
