  • I think something like the Commodore PET might qualify. Back in the day, I saw it used for everything from cash registers to accountants’ workstations, but rarely for anything else.

    I think that the original IBM PC was conceived and marketed as a business machine and only grew beyond that because of Microsoft’s deep commitment to it as a platform and IBM’s uncharacteristicly open specifications and design.

    If not for that combination, the PC might never have left the office and most of us would have stuck with the companies who were actually breaking new ground, Apple and Commodore.


  • Florida House Bill 1 would prohibit children under the age of 16 from using most social media platforms, regardless of parental approval.

    The social media platforms the bill would target include any site that tracks user activity, allows children to upload content or uses addictive features designed to cause compulsive use.

    How would this even work? Let’s take a closer look at the first 2 clauses of the second paragraph:

    A student portal for accessing lessons and submitting assignments would require tracking activity and uploading content. If that system is accessible to students or anyone else from anywhere other than direct connection to the school LAN, then it would be in contravention of this law.

    Or let’s say someone puts up a self-hosted, restricted-access system for extended family to stay in touch without using a commercial or public system (something I’m in the process of doing). Allowing teenagers to use that site would put them on the wrong side of the law.

    Brain damaged authoritarian nut jobs…






  • Are you sure that rounding was broken? Many systems use “Gaussian” or “banker’s” rounding to reduce accumulation of rounding errors. Instead of always rounding to the next larger absolute value at .5, they round to the nearest even number. Although it introduces a bias toward even numbers in the result set, it reduces accumulation of error when .5 is as likely as as any other fraction and odd/even are equally likely in the source.

    I was taught “banker’s” rounding in school (graduated 1974) and have had to implement it a few times to reduce error accumulation.

    If you are looking for a rabbit hole, Wikipedia has a pretty comprehensive article, including an example of how the wrong choice of rounding algorithm led to massive problems at the Vancouver Stock Exchange (Canada).
