The lagging edge

I was taking my daily glance through MacSurfer when I was struck by a press release from WaveMetrics announcing a new version of Igor, the data graphing program. That brought back memories, Igor was my absolute favorite graphing program back when I was in Chemistry grad school in the early 1990s and it could always be depended upon to make the slickest output of the myriad Mac or Windows programs used at what was then called the Center for X-Ray Lithography. I have not seen it since graduating in 1995, and it is good to see it is still alive.

But what really caught my eye, that it is now in 2009 that Igor has moved to Quartz rendering from QuickDraw. According to Wikipedia Quartz was first demonstrated at the 1999 WWDC and has been the recommended mode of rendering on OS X since its introduction. Such is the inertia in the software business that an application as graphically intensive as Igor, a program which would benefit hugely from the modern features one gets for little effort with Quartz, takes 10 years to make the transition.

I wonder if the proximal cause of this laggard transition is the impending doom of Snow Leopard, where QuickDraw using 32-bit apps are distinct second class citizens. A "Pro" graphing app, might well benefit from 64-bit status, and to do that every single QuickDraw call must be expunged. Apple had spent enough time on carrots in making Quartz a beautifully clean API generally superior to QuickDraw in every way, and is now bringing down the stick of enforced obsolescence to bring the last stragglers into the fold.

I will be doing this transition over the course of the summer, myself. I'm down to 800 or so deprecated symbol warnings, so I've a ways to go before the day job application sees 64-bit nirvana.

Star Trek Lessons for Safari

A little noted part of Monday's WWDC keynote was the final feature set for Safari 4. Safari now has searching of browsing history. This reminds me of this exchange in the first season of Star Trek: The Next Generation:

Cmdr Riker: "Data, I need help in locating some library-computer information. All I have is a vague memory of reading somewhere about someone taking a shower in his or her clothing."
Lt. Cmdr Data: "Ah. The body Geordi discovered."
Cmdr Riker: "And I believe it may have happened before."
Lt. Cmdr Data: "To 'someone,' 'somewhere.'"
Cmdr Riker: "Should be easy for someone written up in biomechanical texts."
Lt. Cmdr Data: "About that... did the doctor believe I was boasting?"
Cmdr Riker: "Probably. This may take some time?"
Lt. Cmdr Data: "At least several hours. But what I said was a statement of fact."

It would take Data several hours to search all of Star Fleets records for instances of people showering in their clothes. Such records are quite voluminous. Searching for "shower clothes" gets 23,200,000 hits on Google now, it must be many times more in Data's day.


However, the proper data set to search is every bit of text that Riker had ever read, a much smaller set. As every viewer knows, Star Fleet personnel rarely read paper books, those tend to be kept in glass display cases; they read Kindles. And it wouldn't take much programming to keep track of every page that was ever displayed on a Kindle, or displayed in the browser on your computer.


If I remember seeing a bit of information I now need, like the name of the product manager for Keynote (yes I happen to want to know this), it would be quicker looking in web pages I've seen than it would be googling against all of man's knowledge. I doubt I read as many as 100 pages a day. My browser history says I visited 120 URLs on Monday, and that was a heavy day. Humankind as a whole must be writing 10s of millions of English text pages a day, and has been doing so for quite some time.


But to be truly useful, this data set has to be maintained over one's entire life, and include computers, smart phones, Kindles, and every other gadget that tells us something. So, history search is in Safari, but that's only a start.
