my most pro-windows take is that everyone should have copied io completion ports instead of making usermode software developers reimplement them with extra steps

oh, in case anyone wants an esd sensitive electronics symbol for a pcb or something, feel free to use this: https://git.mildlyfunctional.gay/artemist/play/raw/branch/canon/cad/inkscape/cat_esd.svgoh, in case anyone wants an esd sensitive electronics symbol for a pcb or something, feel free to use this: https://git.mildlyfunctional.gay/artemist/play/raw/branch/canon/cad/inkscape/cat_esd.svg

new transit card!! wait expiry WHEN??@erincandescent @dubiousblur @wxcafe the fact that they're all ascii feels so weird

new transit card!! wait expiry WHEN??@dubiousblur @erincandescent @wxcafe EMV contact cards normally have a file on them named
1PAY.SYS.DDF01
, referred to as the "Payment System Environment", in a standard format that lists applications on the card and settings for it (e.g. priority, languages, human-readable name, application ID)I don't think the application IDs are in either specification, though IIRC they're in a format described by ISO 7816 and are activated using commands in ISO 7816

new transit card!! wait expiry WHEN??@dubiousblur @wxcafe EMV describes the cryptography and application protocols, ISO 7816 describes the packet format and physical layer for contact cards, and ISO 14443 describes the physical layer for contactless cards.
They're built upon one another, each standard has a few different sections describing more layers you could split it up into

new transit card!! wait expiry WHEN??@dubiousblur @wxcafe All US debit cards I've seen have a PAN and can be used over one of the major networks (MasterCard, Visa, Discover, or American Express). When paying with them in person you're sometimes given the option of "debit or credit", where debit goes over an interbank ATM network and credit goes over the credit card network.
I don't remember how this is implemented in the EMV level, other than that there are multiple entries in the PSE

I thought I remembered someone made a USB-C board that was a tiny little thing that would configure USB-PD for arbitrary voltages.@foone The smallest one I know of is https://fpx.oxplot.com/
It's configured by blinking lights on your screen to a light sensor on the board

at least in terms of build performance, loongson 3c5000 SoC seems comparable to the 16-core octeon3 SoC that was in the ubiquiti edgerouter infinity@gsuberland @ariadne it's always been Loongson, though apparently some of their older papers say "Godson"
