Apple Crippled Its DTrace Port

Linnen writes in to note that one of developers of Sun's open source system tracing tool, DTrace, has discovered that Apple crippled its port of the tool so that software like iTunes could not be traced. From Adam Leventhal's blog: "I let it run for a while, made iTunes do some work, and the result when I stopped the script? Nothing. The expensive DTrace invocation clearly caused iTunes to do a lot more work, but DTrace was giving me no output. Which started me thinking... did they? Surely not. They wouldn't disable DTrace for certain applications. But that's exactly what Apple's done with their DTrace implementation. The notion of true systemic tracing was a bit too egalitarian for their classist sensibilities..."

    Like possibly the class system in 1840s England? Marx's work is bullshit, but look at the conditions around him when he wrote it.

    Please give that man some Mod Points. Had to get this far down the page till anyone made any attempt to clue in the clueless as to what the heck DTrace actually does.

    the students. Those academics can be compared to sewer rats, leaving in the damp corridors of Universities, their world has very little connection with reality. Here is my personal encounter with one of those, while I was working for BBN. The guy was from Harvard U and also hold a 'scientist' position at BBN. We had a group meeting, don't remember what was the conversation, but I remember making rather ironical remarks of Soviet Union.

    The guy said, rather thoughtfully: I don't understand why those Russian Emigres are so critical about the Soviet Union.

    (I emigrated from USSR in 1978, at the peak of Brezhnev-era idiocy and revival of Stalinist cult.)

    So I wanted to tell him: because they have some first-hand experience, you idiot. But then I realized I would be taking to the wall.
