  • 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.


  • Yeah, it’s disgusting. What’s arguably worse is that all this has been known for like a decade. There’s all kinds of sound and fury about it now. I figure it’s media manipulation by the really rich fucks as warning shot across chump’s bow to tell him to quit fucking up the economy and stay in his lane. Soon this fury will decline, even here on Lemmy, and he’ll go back to fucking kids or putting them in concentration camps or whatever as long as he quits fucking around with tariffs and global trade.


  • The midpoint to the end of Evolution, humans basically devolve and ultimately go extinct.

    It’s been awhile since I’ve read anything by him as well.

    I remember another book where artifically created people inside a dwarf star were dying due to solar harvesting, IIRC. I remember it being depressing but fascinating. Don’t remember how it ends.



  • On October 25, 2016, allegations were made by two men stating that Trump had attended and partaken in sex parties filled with underage minor females as young as 15 years old who were induced with promises of career advancement.[174] Illegal drugs were also alleged to have been provided to the minors.[175]

    Wikipedia

    There’s another story about Epstein poaching an underage massage parlor worker from chump that pissed him off. Haven’t looked for a source.

    Looks like the party line will eventually be that girls that have gone through puberty are really women and that makes it okay. It’s pretty disgusting, I’m waiting for them to start making a distinction between pedophilla and hebephillia.

    Like a technical distinction where Fox News brings on a tame doctor that explains that it’s normal for older men to fuck/rape 14-15 year old girls.










  • This is a very sharp article. Think I first saw it on Hackaday. I should be using the checklist more often. If there is to be a 3D print bible like Machinery’s Handbook, this article is foundational.

    In particular, chamfers and fillets and their relationship to strength by reducing stress risers is often missed on amateur designs.

    I need to look at crush ribs and ribs for screws/bolts more.

    The idea of a sphere being the most efficent shape is counterintuitive when most mechanical design is inherited from subtractive manufacturing. Also, speed holes reducing strength and increasing material usage is wild. These are powerful ideas that are going to cause almost a philosophical change in manufacturing. It’s going to take decades. Absolutely mind-blowing stuff when you really think about it.

    DFM, in general, is a woefully underappreciated aspect of engineering. One of the great things about 3D printing is that the designer is generally forced to eat their own dog food.

    MEs should recieve more education about DFM. 3D printing would be an easy way to force them to understand the difficulty poor design causes. Of course, DFM for subtractive is a larger and more complex subject, but printing would at least teach the lesson with a little sting.
