    Get fucked, insurance company. Here’s your reminder that, if you’re a California resident, and your health insurance refuses to cover something, it takes all of 5 minutes to file an independent medical review with the state, and statistically, 73% of the time the state will make your insurer pay.

    That’s an insane amount! That is a lot of people getting screwed over, and that’s only the people who reported it who got compensation! And there are people who work for the state who take extreme joy in taking administrative action and fining insurance companies – so far this year, California insurance companies have already been fined $19.7 million, and those are not ‘medical loss’ numbers that count towards the amount of profit they’re allowed to make.

    So do those people at the state a solid. You don’t have to be a green Nintendo plumber to make insurers pay; you can make a difference from your desk. If your insurance company causes you trouble, spend the five minutes to file with the DMHC helpline.

    This year, my insurance plan just decided not to cover a normal preventative lipid and A1C panel for my annual physical, leaving me with a $200 bill from Palo Alto Medical Foundation. The state decided my insurance should pay it after all, and it’ll go into the file to see if they have a pattern of doing this. Blue Shield, get fucked.

    The year is 2009. It's time to set up the speakers. I grudgingly install a PHP-based MPD client from 2005 on a server in the corner named `nyus` since all of the other clients still don't work (even the local Gtk+ ones in the fancy new programming language, Python). It's not a great option, but it's the best that exists to play music, since cloud music is still in its infancy and can't reliably play to a remote machine. I wrestle with PulseAudio until music starts coming out of the speakers. I hit play. Infected Mushroom's new album, Legend of the Black Shawarma, starts coming out of the speakers. I turn it up.

    The year is 2026. It's time to set up the speakers. I grudgingly install a PHP-based MPD client from 2005 on a server in the corner named `nyus` since all of the other clients still don't work (even the local Gtk+ ones in the fancy new programming language, Rust).  It's not a great option, but it's the best that exists to play music, since the cloud has come and gone seventeen times and now only my local collection remains.  I wrestle with PulseAudio until music starts coming out of the speakers.  I hit play.  Infected Mushroom's old album, Legend of the Black Shawarma, starts coming out of the speakers.  I turn it up.

    @jcreed Jason I have wanted to give a !!Con-style talk on how insanely small GNSS signals are because I just cannot even begin to fathom it.

    -107dBm is pretty good for a radio protocol carrying data -- I think Bluetooth LE tends to bottom out around -105 dBm, with most receivers being sensitive more to like -90 or -95 dBm. but once you only have to correlate *known* data, holy shit, you can get to the truly bonkers stuff.

    if you have no idea where you are or what time it is, Sony's receivers can get a lock down to -149 dBm [1]. if you already have an almanac and vaguely know what time it is, you can get a lock down to -163 dBm. and once you already have a lock on some satellites and you're just tracking them, you can keep tracking them down to -167 dBm.

    -167 dBm! what the FUCK! and they can do this while consuming just 6 mW of power!

    IMO this is one of the most magical things we have ever built.

    It was super fun to present my talk, 'the unreasonable effectiveness of the Fourier transform', yesterday at #Teardown2025! It was gratifying to have a full room that mostly seemed to be following along with my ADHD firehose; my goal with this talk is to demonstrate that this sort of radio technology doesn't have to be only the realm of experts, but instead that it can be accessible to almost everyone.

    When I have a video available, I'll post it. In the mean time, here are the resources from it: https://joshuawise.com/resources/ofdm/
