Show HN: PLAttice, for assembling structures much larger than the 3D printer bed
4 by zakqwy | 2 comments on Hacker News.
Struts, nodes, and pins are reversibly assembled into fully 3D printed lattices, trusses, and tree-like structures spanning up to a few meters. I used the system to build a stand for an overhead table lamp which supports a ~1 m cantilevered arm using a tensioned floor-to-ceiling column. If you want to give it a try, find the *.stl files at the bottom of the page; figure ~1 kg of PLA and ~1 day of print time per meter of box truss; pay attention to print orientation; plz respect the license; and definitely print the pin trimming jig.

Show HN: LoopMix128 – Fast C PRNG (.46ns), 2^128 Period, BigCrush/PractRand Pass
8 by the_othernet | 0 comments on Hacker News.
LoopMix128 is a fast C PRNG I wrote for non-cryptographic tasks. GitHub (MIT): https://ift.tt/dreB203 Highlights: * ~0.46 ns/value (GCC 11.4, -O3 -march=native), 75% faster than xoroshiro128++. * Passes TestU01 BigCrush & PractRand (32TB). * Guaranteed 2^128 period. * Proven injective (192-bit state) via Z3 SMT solver; allows parallel streams. * Core requires only stdint.h. Seeking feedback on design, use cases, or further testing.
