Think of taxes as your SaaS (society as a service) bill. Don't want to pay the costs? Then don't reap the benefits.

Oh dang, thanks for writing tpm-fido! It works really well for my use case -- avoiding mandatory and incredibly annoying Duo Mobile 2fa on my school's website -- although I tore the presence verification out of the code for my purposes

I "discovered" this stack through VScode autocomplete when making my website several moons ago. It's a huge improvement in readability over the default serif font, and not much overhead is added!

I'd say PlatformIO is a better analogy -- a framework that lets you use virtually whatever HAL you're familiar with (Arduino, Zephyr, freeRTOS, mbed, etc) with whatever hardware and its corresponding toolchains.

FPGA is literally as parallel as you can make a computation, the ultimate jaunt towards the space end of the time/space tradeoff. Don't like waiting two cycles for your ALU to finish working on previous data? Put another ALU right

You virtually cannot. Short of potting the phone in a slab of epoxy, or welding every seam, helium will find a way to sneak through any rubber gasket, O-ring, etc that seals a phone, even straight from the factory.

Magnetic field strength falls off with inverse square, so it shouldn't be an issue outside of the immediate MRI room. The helium risk to MEMS oscillators is real -- a former employer had an incident involving gaseous helium venting and

Hmm, off the top of my head I think that it takes as much energy to pump water down a 1-foot tube as it would for a 1000-foot tube. It's like rotating a long loop of chain on a pulley, but in three dimensions. One liter of water goes d

I used this approach last year to run a Twitter bot that would report when local pharmacies had 'rona vaccine appointments open up. I scraped the API's of CVS, Rite-Aid, Walgreens, and a few other chains this way. Although I didn&

Reading this article feels almost like satire. An encryption product with an in-your-face backdoor, sporting a dystopian name like “Law Enforcement Access Field"? It’s interesting and very fortunate to see how quickly the tide was turn

That's freaking awesome. For those unaware, the RP2040 microcontroller has several Programmable IO (PIO) cores, which are essentially standalone state machines that read/write directly from memory to the GPIO pins. Unlike bitbangi

Anecdotal, but I've seen figures like "number 263 in line for representative, estimated wait time 8 hours" in the weeks after I got my lemon Pixel 6 and had to get it RMA'd. Even after I got through to a human, it took t
