  • Humana Unsubscribe FAIL

    Quite some years ago, I had a health insurance plan with Humana, although I gave it up because the premiums seemed entirely disproportional to the benefits. They have continued to bombard me with emails telling me how wonderful they are, with an obligatory sentence at the bottom:

    If you do not want us to contact you by email, you can unsubscribe from our online Humana community.

    I do not know anything about this “community” of which they speak, other than that they seem to think I want to be part of it.

    Clicking on the “unsubscribe” link takes me to a page at their randomly named email service, whereupon I check the “don’t send me anything” box and click the “Submit” button:

    Humana Unsubscribe failure

    Did you see the green text near the middle, where my email address should be? Apparently somebody misconfigured the email script to not include the actual address; the %25 gibberish seems to be encoded percent signs, so it may be one of those too-many / too-few / wrong-kind of character escapes.

    Just a typo that could happen to anyone. Right?

    Having once been a customer, I still have an account, but there is no way to control / shut off those messages. Not being a current customer, however, I cannot use their chat interface, which would likely not be productive. I am unwilling to wait on hold for an hour, because I know my call is not valuable to them, and their customer service rep wouldn’t be competent to solve the problem anyhow.

    Fortunately, I can set up a filter to route their emails directly to trash.

  • Walker Leg Shortening

    Walker Leg Shortening

    While looking for something else, Mary came across a walker in the attic and mentioned that, if she ever had to use it, the shortest position of the adjustable legs would put the hand grips too high for comfort. Maybe they

    Well, I can fix that:

    Walker shortening - hole indexing
    Walker shortening – hole indexing

    The holes are an inch apart, so I clamped the V blocks parallel to the X axis on the drill press, zeroed the X axis knob, slid the leg to get the drill bit into the last hole, clamp in place, crank the table an inch, then use a step drill to start the hole:

    Walker shortening - hole drilling
    Walker shortening – hole drilling

    The holes are just slightly larger than the 1/4 inch step on the drill, so the twist drill cuts them to size.

    A tubing cutter sliced an inch off all four legs and all four frame tubes:

    Walker shortening - latch relocation
    Walker shortening – latch relocation

    The white plastic fitting in the frame tube prevents the legs from rattling, but I had to drill another hole to move the latch button, too.

    With a bit of luck, we’ll never need the thing.

  • Simple Pliers Rack

    Simple Pliers Rack

    A Round Tuit™ finished this trivial project:

    Long-handle pliers rack
    Long-handle pliers rack

    Yeah, it’s just seven pairs of holes drilled with a 5/8 inch Forstner bit in a scrap 2×4, which was then introduced to Mr Belt Sander to peel off the dust of ages.

    There’s a spare set of holes in front because I’m absolutely certain that, without them, another pair of pliers would suddenly pop into existence on the bench.

  • Incandescent Bulb Lifetime: Also Better Than Average

    Incandescent Bulb Lifetime: Also Better Than Average

    This bulb spent the last seven-plus years of its life lighting the front bathroom:

    Dead incandescent bulb - 7 years
    Dead incandescent bulb – 7 years

    The green corrosion around the tip seems strange, given that we don’t use the tub or shower in that bathroom, and I’m pretty sure it wasn’t the cause of the failure.

    My stock of incandescent bulbs will eventually run out; I must figure out how to light the deaders in an attractive manner.

  • Lyme Disease, Now With Bonus Babesiosis

    Lyme Disease, Now With Bonus Babesiosis

    Two weeks of doxycycline should kill off all the Borrelia bacteria responsible for Lyme disease, but a blood test shows the antibodies:

    Lyme test - 2021-11-10
    Lyme test – 2021-11-10

    Those antibodies will gradually disappear during the next few months and, unfortunately, a past Lyme infection does not prevent future infections.

    The tick also injected Babesia parasites which do not respond to antibiotic treatment:

    Babesia test - 2021-11-10
    Babesia test – 2021-11-10

    The “titer” refers to the dilution required to produce a negative test result, with the 1:64 reference titer representing six successive 50% dilutions. My blood required ten 50% dilutions to produce a negative result for the IgG antibodies and (presumably) six 50% dilutions from a 20% base for the IgM antibodies.

    As I understand the situation, IgM antibodies appear promptly upon infection and IgG antibodies follow along later, so my reaction to the Babesia infestation was ramping up after two weeks.

    In the Bad Old Days™, quinine was the go-to treatment for parasitic infections, but it has a host of horrific side effects at the dosage required for traction against actual diseases; tonic water ain’t gonna get you where you need to go.

    The new hotness is atovaquone, arriving as 100 ml of a yellow liquid with the consistency of latex paint, (allegedly) the taste of “tutti fruitti“, and a price (modulo your drug plan) making inkjet printer ink look downright affordable. You might expect to get a 5 ml measuring spoon along the the bottle, but suffice it to say it’s an exceedingly good thing I’m well stocked for printer cartridge refilling.

    All of the diseases and drugs list “fatigue” / “drowsiness” / “malaise” as symptoms / side effects and I’m here to tell you knocking off a couple of hours in the recliner during the day does nothing at all to disturb another nine hours in the sack overnight.

    A few weeks of low productivity in the Basement Shop™ will definitely count as a successful outcome.

    Protip: We need permethrin spray. Lots permethrin spray.

  • Raymond Avenue Road Furniture Graveyard

    Raymond Avenue Road Furniture Graveyard

    Apparently the traffic calming features along Raymond Avenue sacrifice the road furniture:

    Smashed Raymond Avenue Road Furniture

    I hadn’t realized the “standards compliant” road design caused the death of so many street lights, but the dead bollard population is definitely under-represented. In round numbers, every traffic circle (“intersection”) always has at least one smashed bollard in addition to the vestigial stumps of those removed rather than being replaced.

    The upright bollard is a relic of the earliest installations, back before they realized a bollard with an eye-level light glaring into drivers’ eyes weren’t an effective design, particularly along a road lined with dead-black / non-reflective posts.

    Spotted in the Town of Poughkeepsie Highway Department compound.

  • CFL Lifetime: Better Than Average

    CFL Lifetime: Better Than Average

    Although compact fluorescent lamps have fallen out of favor, I’m burning through a box of the things donated by a friend who upgraded to LEDs and figured I could put them to good use. In general, complex electronic doodads (like CFL or even LED lamps) used in hostile situations (like an ordinary downlight fixture) seem to fail too quickly to justify the power savings; searching for “cfl fail” will produce some evidence from around here.

    One of the downlights in the Basement Office just killed this specimen:

    Dead CFL - detail
    Dead CFL – detail

    Much to my surprise, however, it survived for more than five years:

    Dead CFL - over 5 years
    Dead CFL – over 5 years

    The previous CFL bulb in that fixture lasted only two years, so their average lifetime is entirely too short.

    A taller bulb does a better job of lighting up that corner, although it started with enough power-on hours to suggest it won’t survive for another five years:

    Dead CFL - replacement
    Dead CFL – replacement

    The ghostly humps above the overexposed glare are the long CFL tubes reflected inside the Pixel’s camera optics.

    I didn’t see much point in nailing a ceiling to too-low floor joists.
