I was just reflecting on yesterday&#x27;s hack of my 81 hacks, considering the possibility of adding an asm.js code generator to it: <a href="http:&#x2F;&#x2F;canonical.org&#x2F;~kragen&#x2F;sw&#x2F;81hacks&#x2F;oscarray&#x2F;notes" rel="nofollow">http:&#x2F;&#x2F;canonical.org&#x2F;~kragen&#x2F;sw&#x2F;81hacks&#x2F;oscarray&#x2F;notes</a>.  Being able to run that code in Chromium as well as Iceweasel would be a big benefit!  Especially if Chromium adds SIMD.js as well (currently only in Firefox nightly; see <a href="https:&#x2F;&#x2F;blog.mozilla.org&#x2F;javascript&#x2F;2015&#x2F;03&#x2F;10&#x2F;state-of-simd-js-performance-in-firefox&#x2F;" rel="nofollow">https:&#x2F;&#x2F;blog.mozilla.org&#x2F;javascript&#x2F;2015&#x2F;03&#x2F;10&#x2F;state-of-simd...</a> for more details) since that would enable JS code to generate code at runtime that would get performance several times better than optimized C, at least for the kinds of graphics, DSP, and machine learning problems that are easy to implement in SIMD.<p>SIMD.js still looks pretty half-baked (you can&#x27;t supply vector arguments to provide the indexes for shuffling? Really?) but already promising.
