  • Lead shot for waterfowl hunting has been banned in the US for a few decades. It’s still used for upland bird hunting. I think it’s still frequently used illegally for waterfowl.

    Not an expert, but have a decent layman’s understanding. Could totally be wrong about the next part:

    It’s my understanding that lead contamination of wild animals through hunting primarily occurs due to various sizes of bird shot. The greater surface area allows a much higher level of contamination. It also forms lead dust in the shell from friction and when fired. It’s also easier for animals to eat it. Rifle rounds and slugs are fairly inert as the larger size prevents most consumption and less absorption when it is consumed.



  • I often code directly on the machine control, including single blocking a running program and adding a line while the program is paused.

    Editor on older CNC machines usually doesn’t even do lowercase and often has limited alphabet keys. Think '80s green or amber screen.

    A machinist’s coding workflow can be real fucky. I go from CAM which is like a highly complex visual programming IDE to notepad. If I’m being fancy I use notepad++ for syntax highlights and diff’ing.



  • G Code is basically a geometric scripting languge and isn’t Turing complete in basic implementations. Every manufacturer pretty much also has their own dialect that is Turing complete.

    Gcode with control commands and variables is called, no shit, Macro G Code. It’s Turing complete. That form of variable names is normal and is inherited from hardware registers/banks and TTL.

    It’s not unusual for a save dialog to be labelled Punch as it has a direct lineage from punch tape.

    Kind of like assembly and a graphing calculator had an abortion together.


  • Trichocereus bridgesii, monstrose form. Called penis cactus or toothpick cactus depending on spines. T. bridgesii contains higher levels of alkaloids, including mescaline, than the more commonly used T. Pachnoi “San Pedro”. The monstrose form is said to be particularly potent, although it is slower growing.

    I very much agree. It is held up as this wonderful parable of how you should live. It’s the sort of thing that the powerful use to take advantage and abuse the weak.

    This kind of puerile shit is bad for children and is just like a lot of the Jesus crap that gets pounded into kids.










  • Correct! Insects have spiracles that basically passively exchange air. Max size is basically determined by this.

    IIRC, some caterpillars only stop growing and pupate when they run out of a growth hormone.

    I always wondered what would happen if you grew them in a high oxygen tank and supplemented their diet with the hormone.

    Maybe get a Mothman that way.
