    SpaceX acquires xAI, plans 1 million satellite constellation to power it

    They may have a stupid plan, but I am pretty sure even their stupid plan calls for launching > 1 satellite per day.

    Mercedes teaches its driver assist how to handle surface streets

    Except that the radar completely stopped working when the front of the car was covered in a thin layer of snow or ice. And then there were overpasses...

    Mercedes teaches its driver assist how to handle surface streets

    Seems crazy that you would be ok with only every single car using it. What about bikes? dogs? children? cows? tree limbs? mattresses? ladders? trains? horse drawn carriages? deer? I think it should remain no-go for you until all of them are using it.

    Tesla safety driver falls asleep during passenger’s robotaxi ride

    The actual monitoring is still in place. From the original reddit post:

    Feds probe Tesla about its “Mad Max” mode

    Teslafi ( https://www.teslafi.com/firmware.php ) suggests that this option is available on 2% of the fleet (and most of them got it yesterday).

    Feds probe Tesla about its “Mad Max” mode

    Because they want their product to be used? Anyway 4 or 5 years ago, after some NHTSA investigation, Tesla was seemingly forced to make changes. The vehicles now always come to a complete stop at stop signs as opposed to optionally rolling at three miles per hour through the stop sign. The...

    Feds probe Tesla about its “Mad Max” mode

    When I first heard the name, my first thought was having to tell a jury that you put your car in Mad Max mode. I don't even know what the movies are about, but having a driving option with mad in the name seems mad. Seemingly this is just two numerical options (max speed multiplier and some...

    Encryption made for police and military radios may be easily cracked

    For example, on July 6, 2016 police officer Jeronimo Yanez shot Philando Castile. One of the few pieces of evidence introduced at the trial of Yanez was the radio traffic on ARMER talkgroup 10430 (St Anthony Car to Car) where they discuss why they were stopping the car. At that time, it was not...

    Encryption made for police and military radios may be easily cracked

    I think the Motorola ADP is 40 bit. At least in my part of the country almost all of this was transmitted without any encryption a few years ago. The strength of the encryption doesn't really matter. Any degree of encryption means that it won't be available to scanners and scanner apps and the...

    Encryption made for police and military radios may be easily cracked

    In the US, P25 radios are commonly used for public safety. While there is a weak motorola proprietary encryption occasionally used, generally DES (56 bit) or AES (256 bit) are used.

    Reusable rockets are here, so why is NASA paying more to launch stuff to space?

    LSP launches are the launches with the requirement that all previous launches by the same type of rocket be analyzed before flight, right? Meaning they create a weird bubble where you can't launch anything for a few days before an LSP launch. Or am I misremembering?

    More than 376,000 Tesla Model Y, Model 3s have faulty steering

    https://static.nhtsa.gov/odi/rcl/2025/RCLRPT-25V092-6812.PDF That seems quite different from 570 crashes.

    Trump declares sweeping power over independent agencies such as FCC and SEC

    I think you let the kind of grand "Federal Election Commission" name confuse you. They don't have anything to do with who won an election. They collect reports on who contributed to what campaign. As they say on their website: US campaign finance laws are weak enough and contain enough...

    As NASA flies into turbulence, the agency could use a steady hand

    I don't have any data, but I would guess that "morale at the agency is 'absurdly low'" would apply at many federal government agencies.

    Greenland’s glaciers are falling apart faster than expected

    I am sure I am missing something obvious, but I can't figure out what it is. 9 * 24 * 365 =78,840. So, 78,840 gigatons lost/year, but only 1,000 gigatons freshwater flow/year? How are the other 77,840 gigatons lost?

    Report: Elon Musk failed to report movement required by security clearance

    What does such a manager actually do then? It seems like a terrible way to manage anything. Is this part of why so many government projects seem so screwed up?

    Hospitals adopt error-prone AI transcription tools despite warnings

    Doctors are still required to read and correct these documents before signing them, right? ;)

    Are Tesla’s robot prototypes AI marvels or remote-controlled toys?

    Tesla also streamed the event on YouTube. View: https://youtu.be/6v6dbxPlsXs?t=3165 SpaceX does the annoying only on X thing, but Tesla does not, so far.
