    Here's a PoC that confirms my hunch. *Neither* of these windows use JavaScript but the position of the cursor in the left window is sent to the right window. This works on Tor Browser with JS disabled.

    I hope one day I'll get a chance to vote Ayanna Pressley for President. She's one of the most powerful, captivating, and relatable personalities in modern politics. When she talks people shut up and listen.

    I just asked RUDY if BOLTON made up the mtg: “I think he’s making some of it up. He’s sure making up — I wouldn’t call it making it up, but he’s acting like a real scumbag by never telling me that he objected once, & then saying I was a time bomb, or a firecracker or something."

    Roberts, presiding over this impeachment trial, should be alarmed by the fact that part of the defense team was directly involved in the crime. Equally so that Nunes was also implicated early despite his involvement in the House investigations. All of this is very shady.

    With all of the news about viruses, impeachment, and primaries I almost forgot that the UK was ceremoniously shooting itself in the foot today.

    It's exciting to see my library featured in a YouTube video.

    I'm going to consider this a success. The satellite signal was caught from indoors using the same antenna/demodulation setup as before but this time NOAA 15 flew almost directly above Austin. Unfortunately it's really cloudy today, but still... It works!

    There are only a couple of things that make sense to me... Rent-a-scooter devices that need cellular. Or do they, since users are carrying a phone? Embedded data collection in IoT devices that can phone home with user data, in an unstoppable way, regardless of local network.

    I still don't understand the appeal of cellular-embedded IoT and that angle of marketing behind 5g. It seems like a waste of SIM/GSM tech, power, etc, compared to using lower-power, and free m2m, like LoRa and BLE (plus a nearby hub of some kind if outside access is needed).

    Hey all I am still working on Widget the companion robot dragon, this ks V3 and so far I like the design much better. It needs a bit more and a field test before I publish it.

    The signal from this one is too weak for an image (it's east of FL and I'm in TX) but this is what their waterfall plot looks like for anyone curious.

    I'm gradually getting better at capturing these. So far the best demodulation settings seem to be using a bandwidth of 45 kHz, a narrow FM with maximum deviation of 17 kHz. Still using a horizontal 120° dipole 52cm rods.

    Not only did Rand Paul just break the law in front of the Chief Justice of the Supreme Court by trying to name the whistleblower, he also illegally left the chamber to give a press conference. Where’s the sergeant at arms?
