  • There’s some weirdness on that because she did some important but not-very-public work at IBM in the 60s with their ACS/“Project Y” effort that did what we later call superscalar/multi-issue processors like …20 years before those terms existed. As part of that she wrote a paper about “Dynamic Instruction Scheduling” in 1966 under her pre-transition identity that is a like retroactive first cause for a bunch of computer architecture ideas.

    There was almost nothing about that work in public until Mark Smotherman was doing some history of computing work in the late 90s, put out a call for information about it, and she produced a huge trove of insider information after deciding it was worth exposing the provenance. There’s a neat long-form LATimes piece about the situation which is probably the primary source for the history in OP’s link.


  • Another Tears of the Kingdom here.

    I’m like … 5/3 subscribed between professional and personal obligations for the next several months, so don’t have time for that in my life.

    When I got around to Breath of the Wild in late 2020, I arranged it so I could basically take a vacation from reality to Hyrule for over a week with it, and the experience was delightful, so I want to hold off until I can properly enjoy it.

    I did similar things at the ends of periods of over-obligation with Fallout: New Vegas and Skyrim (earlier, but both years after their release), I’m a sucker for disappearing into an open-world RPG as a vacation.


  • I’m somewhat surprised to learn that each Snowmobile unit is only about 100PB in a 45x8x9.6ft highwall shipping container

    Gonna ballpark in stupid units to see how wrong my intuition that that’s not very dense is:

    Assuming dense but not hot new thing spinning rust, 16TB per 34.5 cubic inch standard 3.5" disc.

    (100PB/16TB)*2 (assume at least two spindle redundant) is about 12,000 discs, so about 414,000 cubic inches of just discs without any of the supporting equipment.

    A highwall shipping container is like 5,900,000 cubic inches, so only like 7% of that thing would be discs.

    Or, accommodating a little bit of the support, let’s say it’s just full of those commodity 90-bay 4U storage servers. Those are 19" x 7" x 26.4" (3511.2 cubic inches) for 1440 raw TB each, again 2 spindle redundancy so you’d need about 140 of the things for 100PB, round up to 500,000 cubic inches of those… still less than 9%.

    Yeah, unless I did my math radically wrong, that’s surprisingly not very dense.
