Dodecahedrant Edition

Tech News

  • There were at least two chips available in 1983 that could have handled my wavetable synthesis requirements for the Imagine: The TMS32010 which as we've noted cost around $500 a pop, and the 80286, which reduced the 70 cycle 8x8 multiply on the 8086 to 13 cycles.  The 68000 could do a 16x16 multiply in a maximum of 70 cycles, so its worst case was twice as fast as an 8086's best case, but not quite fast enough.

    Still, calculating the number of bits multiplied per second, I'd only need about 3% of a TMS32010 to handle 10-voice 10-bit wave synthesis.  That's something that could have existed even if it didn't.

  • Nice work if you can get it.  (Quanta)

    Mathematicians have been wondering for two thousand years if you can travel a straight path on a dodecahedron, starting at one vertex and returning to that starting point, without ever encountering another vertex.

    On the other Platonic solids, it's long been known that you can't.

    On the dodecahedron, turns out you can.

    It's also the best die in D&D.

  • Hacker News wasn't actually down.  It's just that nobody could get there because BGP.  (Cloudflare)

    BGP considered harmful.

  • Pinterest has decided it doesn't need a $90 million artist's rendering.  (SFGate)

    The company paid $90 million in penalties to terminate its lease agreement on a yet-to-be-completed office building.

    Expect more of this.  It will probably be ultimately good for everyone, except the SF city council.

  • Apple is working on 5nm in-house GPU chips.  (Tom's Hardware)

    This is the undropped shoe of moving Mac to Arm.  I have less than no interest in buying another Mac, now or after the transition, though I might need to at some point just to compile code for it.

    After being delighted with my original Nexus 7 I bought an iPad as well.  The retina screen was great, but the operating system and user interface were terrible and - more importantly - could not be fixed.  Apple are doing the same to the Mac.

  • Even Jonathan Swift would have trouble with this one.

  • The reason not to burn down cities is that it might help Trump.

  • Ugh.

  • Overhead, without any fuss, the stars were going out.

Disclaimer: Well, except for Sirius B, which decided to be an asshole about the whole thing.
