Arthur T Knackerbracket has processed the following story:

Purdue University innovators have created technology aimed at replacing Morse code with colored “digital characters” to modernize optical storage. They are confident the advancement will help with the explosion of remote data storage during and after the COVID-19 pandemic.

[...] Rather than using the traditional dots and dashes as commonly used in these technologies, the Purdue innovators encode information in the angular position of tiny antennas, allowing them to store more data per unit area.

"The storage capacity greatly increases because it is only defined by the resolution of the sensor by which you can determine the angular positions of antennas," said Alexander Kildishev, an associate professor of electrical and computer engineering in Purdue's College of Engineering. "We map the antenna angles into colors, and the colors are decoded."

[...]This new development not only allows for more information to be stored but also increases the readout rate.

"You can put four sensors nearby, and each sensor would read its own polarization of light," Kildishev said. "This helps increase the speed of readout of information compared to the use of a single sensor with dots and dashes."

Future applications for this technology include security tagging and cryptography. To continue developing these capabilities, the team is looking to partner with interested parties in the industry.

    The original, decimal version is: "There are three kinds of people in this world, those who can count, and those who cannot."

    I would have expected the average Soylentil AC to get that the equivalent in binary is 11, not 10. But as Mark Twain said, explaining a joke is like dissecting a frog; neither the joke nor the frog survives.

    except that nobody except you knows the original decimal version.
    which seems to be a completely different joke in any case, since the funny comes from the inability to count.
    whereas for the programmer version the funny comes from the assumption that '10' is written in decimal.

    and, just in case: i can be even more unfunny if needed.

      Eratosthenes seems to know it, and if he knows it, that means everyone knows it, except for rando ACs on SoylentNews.
