Who’d’a thunk it?

  • Price Scanner: Connection Refused

    I loves me some good error message:

    Price Scanner - Connection Refused
    Price Scanner – Connection Refused

    A closer look:

    Price Scanner - Connection Refused - Detail
    Price Scanner – Connection Refused – Detail

    If the popup appeared just one pixel lower, you could easily decode the message behind it; perhaps * Out of Service * fits?

    At least it doesn’t show an OK? button.

  • Oxygen Sensor Wrench Pricing

    The price for this specialized wrench used to extract oxygen sensors took a big jump some time after I added a link to it:

    Northern Tool Sensor Socket - Absurd Lowest Price
    Northern Tool Sensor Socket – Absurd Lowest Price

    Were it not for the very specific part number that’s certainly not available anywhere else, you could take advantage of their “Guaranteed Lowest Prices” to make a quick $494.

    As my buddy dBm puts it: “Such a deal!”

  • Powers of Two: The List

    A few sheets of fanfold “computer paper” emerged while tossing stuff out. The first page suggests somebody was trying out some simple programming:

    Powers of 2 Listing - top
    Powers of 2 Listing – top

    Seven pages later, you can tell an extended-precision library was hard at work:

    Powers of 2 Listing - bottom
    Powers of 2 Listing – bottom

    This being mainframe line printer paper, somebody must have donated it to my heap; I have no memory of ever doing (or needing to do) extended-precision math. That’s my story and I’m sticking with it.

    More than you care to know about Powers of Two.

  • Bent Tap: Huh?

    The Shapeways bronze-infused stainless steel process reportedly produces objects so hard that they require carbide tooling, so I wasn’t too surprised when this magazine block rounded the threads right off a tap:

    Browning Hi-Power magazine - steel block trial fit
    Browning Hi-Power magazine – steel block trial fit

    The tap turned up while I was clearing off the bench and, seeing as how the upper half of the threads weren’t ruined, I thought maybe I could at least get a bottoming tap out of it.

    Step 1: snap off the damaged part. This should be easy, as tap steel tends to punish you when you’re not doing it right. So I grabbed the ruined section in the bench vise and gave the shank a stiff whack:

    Bent tap
    Bent tap

    Now, that is not a nominal outcome

    The tap came from a set of dubious provenance that’s conspicuously labeled: JUNK METRIC. I have no idea where it came from, as it’s slightly younger than dirt. There’s a Craftsman metric set in the same drawer with much better steel (yes, I’ve snapped a few taps) that I normally use; I figured if I was going to wreck a tap on that magazine block, I should wreck a junk tap.

    Maybe that Shapeways stainless isn’t quite as nasty as it seems…

  • Unsealed Camera Box

    Used to be, back in the day, that when you got a box full of shiny new electronics, it bore stickers: “Do not accept if seal is broken” or “Factory sealed” or “Genuine product” or something like that. When you slit the seal, you had some confidence that the last person to look in the box sat at the end of their production line; I’ll grant you that counterfeit stickers have become cheap & readily available, but it’s the principle of the thing.

    Nowadays, a shiny new Canon camera arrives in a box with a tab tucked into a slit:

    Canon Camera box - unopened and unsealed
    Canon Camera box – unopened and unsealed

    The box looked unopened and everything inside seemed in order, but … even though I’d seen this before on other cameras, it’s still disconcerting.

    I’m unsure of the story about laminate flooring in the camera box.

  • MHV LUG Lightning Talk: Intro to NSA Hardware Implants

    Meme - Nixon - I see what you did there - 5x38k
    Meme – Nixon – I see what you did there – 5x38k

    I did five minutes of standup comedy at yesterday’s MHV Lug meeting, pointing out some of the more interesting ways to compromise a PC when you have an infinite budget for development and consumables.

    You don’t get my patter with the PDF (unless you had access to the room’s bugging hardware), but the links may come in handy in the unlikely event you haven’t been following the story closely.

    If you have a security clearance or are in line for one, you probably shouldn’t click on the link, because it contains copies of pages from the leaked NSA catalog:

  • Santa Ride: Crash Report

    While walking from the Metropolitan Museum of Art to Grand Central on a frigid post-Christmas December evening, we encountered this storefront display:

    Santa Ride - car
    Santa Ride – car

    A closer look at the monitor in the background:

    Santa Ride - crash report
    Santa Ride – crash report

    Hmmm. Bit of a surprise: not a Windows box.

    After walking two miles along Madison Avenue, I didn’t see one single item in the store windows that I’d buy, even in the after-Christmas discount season. Mary wasn’t enthralled by a pair of diamond-encrusted emerald earrings the size of my thumbs, either, which is likely a Good Thing.

    We stopped in the Ugg Boot Store, both to warm up and  so I’d know what all the spammers have been hawking…
