    Apple's Pr=

    provided developer cl=

    Apple silicon could offer better AI inference

    Germany's Wendelstein 7-X, =

    last May by magnetically 'bottli=

    Oxford, England, achieved even longer containme=
    nt times of up to 60
    seconds in final experiments before its retirement i=
    n December 2023.
    These results, among other recent advances in the field,=

    CACHING IS AN ABSTRACTION, NO=
    T AN OPTIMIZATION (5 MINUTE READ) [11]=20

    Caching is best understood as=
    a tool for making software simpler
    rather than as a tool to improve perf=
    ormance. It resembles an
    abstraction rather than an optimization. Underst=
    anding this makes it
    possible to come up with designs that work and satis=
    fy the functional
    requirements of systems from the perspective of 'having=
    adequate, fast
    access to the data it needs'. The problem should be figur=
    ing out how
    to get data into fast storage as often as possible instead of=
    gaming a
    system that is holding data access storage.=20

    Germany's Wendelstein 7-X, an advanced = fusion reactor, set a record last May by magnetically 'bottling up' superhe= ated plasma for 43 seconds. The large Joint European Torus (JET) fusion rea= ctor near Oxford, England, achieved even longer containment times of up to =
    60 seconds in final experiments before its retirement in December 2023. The=

    <span style=3D"font-family: &quot;Helvetica Neue&quot;, Helvetica, Arial, V= erdana, sans-serif;">
    Caching is best understood as a tool fo=
    r making software simpler rather than as a tool to improve performance. It = resembles an abstraction rather than an optimization. Understanding this ma= kes it possible to come up with designs that work and satisfy the functiona=
    l requirements of systems from the perspective of 'having adequate, fast ac= cess to the data it needs'. The problem should be figuring out how to get d= ata into fast storage as often as possible instead of gaming a system that =
    is holding data access storage.
