Open Source--It's in the Genes


What happens when you release 500,000 human genomes as open source? This.
DNA is digital. The three billion chemical bases that make up the human genome encode data not in binary, but in a quaternary system, using four compounds—adenine, cytosine, guanine, thymine—to represent four genetic "digits": A, C, G and T. Although this came as something of a surprise in 1953, when Watson and Crick proposed an A–T and C–G pairing as a "copying mechanism for genetic material" in their famous double helix paper, it's hard to see how hereditary information could have been transmitted efficiently from generation to generation in any other way. As anyone who has made photocopies of photocopies is aware, analog systems are bad at loss-free transmission, unlike digital encodings. Evolution of progressively more complex structures over millions of years would have been much harder, perhaps impossible, had our genetic material been stored in a purely analog form.

Samsung, Red Hat to Work on Linux Drivers for Future Tech
The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world.
Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility.
