    Subject: Re: Manufacturers have less than five days' supply of some computer
    chips, Commerce Department says (WashPost)

    This is a rather gratuitous attack on the telecoms. In no way was this a technical problem or a commercial problem.

    All other countries had no problems with the rollout, only the US botched
    it.

    I looked up the technical reports from Canada, Japan, US. All the reports
    were completed in plenty of time. Japan did bench experiments as did US. All other countries proceeded to issue guidelines - don't be too close to glide path, don't point antenna up. For some reason, US FAA/FTC did nothing after
    the technical committee report.

    Some say but the US frequency is closer:

    * Altimeters are 4200-4400 MHz (World wide, no other users)
    * Japan 5G is 3600 - 4200 MHz , 4400 - 4900 MHz; touch the Altimeter
    spectrum on both ends
    * US 5G is 3100 - 3550 MHz, 3700 - 4200 MHz ; touching on the lower end

    If Japan can roll it out, it's hard to see how US has a harder problem.

    ... From the cited article:

    A covid outbreak, a storm, a natural disaster, political instability,
    problem with equipment -- really anything that disrupts a [chip-making] facility anywhere in the world, ``we will feel the ramifications here in the United States of America,'' Commerce Secretary Gina Raimondo said. ``A covid outbreak in Malaysia has the potential to shut down a manufacturing facility
    in America.''

    American semiconductor plants are not magically immune from covid outbreaks, storms, natural disasters, and problems with equipment. There might be a
    good reasons for the U.S. government to give highly profitable companies $52 billion in taxpayer subsidies, but it such a reason exists, the Commerce Secretary is keeping it to herself.

    Subject: Re: Alexandria VA red light cameras don't follow the law

    Alexandria VA (suburb of Washington DC) is refunding nearly 5000 tickets / $200K in fines because of an error in the software: the problem was that the software didn't account for a half-econd grace period (after the light turns red) written in the law. The company that operates the cameras found it -- although I wonder how many other cameras have this problem (or similar problems) but there's no accountability.

    My recollection is that these automated tickets aren't reported to insurance companies and don't incur points, so it (shouldn't) have increased anyone's rates or caused anyone to lose insurance.

    [Incidentally, the Virginia law is explicit on this, so it's not a matter
    of whether the software designer came up with the rule: "All traffic light
    signal violation monitoring systems shall provide a minimum 0.5-second
    grace period between the time the signal turns red and the time the first
    violation is recorded." https://law.lis.virginia.gov/vacode/title15.2/chapter9/section15.2-968.1/
