  • Comment Spam Attack

    Comment Spam Attack

    Of late, the blog has been getting 500 hits per day, with 60-ish on the main page and 30-ish on the post of the day. The “Hot Topics” posts (over in the right column, down a bit) account for a scant hundred more hits, with the remaining 300 hits distributed in onesies and twosies along the very, very long tail of 4200 posts.

    Then this happened:

    Spam Attack - Page Hits
    Spam Attack – Page Hits

    It seems a spammer noticed my posting activity and unleashed either a script or, more dismally, a stable of low-wage third-world workers to make a comment on every single post in the blog.

    The Akismet scanner flagged three dozen comments made on the most recent posts, with the remaining 4500 (!) page views producing zero comments, because, some years back, I had disabled comments on posts older than a few dozen days. I disliked doing so, because I value comments from folks who contribute to the discussion, but …

    The IP addresses seem to point back to compromised servers and pwned Windows boxes in the US, with very few foreign sources. The comments themselves consist of the usual gibberish, often run through a thesaurus (known as “spinning”) to improve the odds of evading the detectors. The payload seems to be the URLs attached to the random user names, all pointing to sites touting Vietnamese (!) scams, Russian pharmaceutical sources, online gambling dens, and the like.

    And then, after two days, it was over.

    Which is why I really really do not want to manage my own blog infrastructure, infuriating as WordPress-dot-com’s editor might be.

  • Bike Helmet Mirror: Brasswork Clamp

    Bike Helmet Mirror: Brasswork Clamp

    A bit of Quality Shop Time produced a slight improvement to the clamp holding the mirror to the stalk:

    Helmet Mirror Ball Mount - mirror joint brasswork
    Helmet Mirror Ball Mount – mirror joint brasswork

    The general idea is to hold the wave washer (it’s mashed under the flat washer, honest) above those bumps on the plate holding the mirror and stalk balls. It’s a few millimeters from the end of a ¼ inch brass rod, drilled for the M3 screw, and reduced to 4.5 mm with a parting tool to clear the bumps.

    While I was at it, I made two spare mirrors, just to have ’em around:

    Helmet Mirror Ball Mount - new vs old
    Helmet Mirror Ball Mount – new vs old

    The new ball mount looks downright svelte compared to the old Az-El mount, doesn’t it?

    I should replace the steel clamp plates with a stainless-steel doodad of some sort to eliminate the unsightly rust, but that’s definitely in the nature of fine tuning.

  • More AAA-to-AA Alkaline Adapters

    More AAA-to-AA Alkaline Adapters

    Having a handful of not-dead-yet AAA alkalines and a bunch of LED blinkies built for AA alkalines, a pair of adapters seemed in order:

    AAA-to-AA Alkaline Adapters - installed
    AAA-to-AA Alkaline Adapters – installed

    The blinkies need a somewhat wider base than they’d get from a pair of AAA alkalines, so it’s not quite as dumb as it may seem.

    In any event, the positive terminal comes from a brass rod:

    AAA-to-AA Alkaline Adapters - brass terminal
    AAA-to-AA Alkaline Adapters – brass terminal

    Nobody will ever see the fancy Hilbert Curve infill around the brass:

    AAA-to-AA Alkaline Adapters - end view
    AAA-to-AA Alkaline Adapters – end view

    In this application, they’ll go from not-dead-yet to oh-it’s-dead faster than AA cells, so I can watch how the blinkies work with lower voltages.

    After grating the nutmeg, continue with this:

    Mary omits the cloves.

    Applesauce is completely optional. Should you prefer a softer & sweeter loaf, give it a try.

    Conversely, reduce the sugar by about half if you’ve accustomed yourself to a keto-oid diet; the raisins carry enough sweetness for us. You can use brown sugar if you like.

    Obviously, cooking is not an exact science; a recipe is just where you start …

    Algorithmic pricing / money laundering is a thing:

    Ya can’t make this stuff up …

  • Keyboard Tray Raising

    Keyboard Tray Raising

    Long ago and far away, I moved the keyboards off our desk surfaces to a more convenient location on a tray under the middle drawer. Mary’s desk recently gained a somewhat thinner keyboard with a thumbwheel volume control, so she wanted the tray moved up:

    Keyboard Tray Relocation - in place
    Keyboard Tray Relocation – in place

    The supports on either side started out as 2×4 lumber with a slot cut (using the radial arm saw I no longer have) for the aluminum sheet:

    Keyboard Tray Relocation - support view
    Keyboard Tray Relocation – support view

    For the record, a pair of screws hold each support to the drawer:

    Keyboard Tray Relocation - support screw
    Keyboard Tray Relocation – support screw

    Not elegant. Works fine. Good enough!

    Tiny Bandsaw™ wasn’t designed for ripsawing lumber, but the same Proxxon 10/14 TPI blade I use for aluminum worked better than I expected to lop a 1-¼ inch strip from the wood slats:

    Keyboard Tray Relocation - bandsaw fixture
    Keyboard Tray Relocation – bandsaw fixture

    That’s a reenactment based on a true story. The wood scraps clamped on the bandsaw table leave enough clearance for the 2×4 slide to freely, yet not enough for the blade to wander off track.

    You can tell how long ago I built the original trays: nary a trace of 3D printing!

  • Nutmeg Season

    Nutmeg Season

    Well, it’s really zucchini bread season, with grated nutmeg among the spices (*):

    Zucchini bread - minus QC sample
    Zucchini bread – minus QC sample

    Having recently bought a very sharp grater, I hauled out a small vise to save my fingertips:

    Nutmeg grating - mini-vise
    Nutmeg grating – mini-vise

    The dark lunette comes from a previous clamping attempt; it takes a while to find the most secure pin arrangement.

    Grate a flat:

    Nutmeg grating - first flat
    Nutmeg grating – first flat

    I’ve always enjoyed the surprisingly intricate patterns inside what looks like a bland nut.

    Flip it over, flatten the other side, and grab it in an even smaller vise:

    Nutmeg grating - flat clamping
    Nutmeg grating – flat clamping

    In truth, that vise is intended for small cylinders, not flattened nuts, but I figured it’d suffice for light-duty use. Grate parallel to the vise screw, reclamp as needed, and it worked out reasonably well.

    Eventually, you have a pile of powder and one cubic nutmeg:

    Nutmeg grating - results
    Nutmeg grating – results

    I’m sure there’s a way to grate the remaining cube, but I’m unwilling to shred my fingertips.

    Tip the powder into a small jar and repeat as needed. Each nutmeg produces about 5 grams and I did three of the things this time.

    Yummy!

    (*) We omit the cloves and knock the sugar down by half. Your tastes will surely differ.

    Update: Mary’s recipe!

  • Long-gone Labeling

    Long-gone Labeling

    These appeared while I was extricating the 3-axis positioner from an old project:

    Migrated felt-tip pen labels
    Migrated felt-tip pen labels

    I’m reasonably sure those labels started with blue ink from my all-time favorite Ultra-Fine-Point Sharpie markers on address labels covered with ordinary matte tape. Fourteen years on, the X, Y, and Drive legends are pretty much indistinguishable.

    Nothing lasts …
