  • Brittleness didn’t get talked about enough. I couldn’t figure out why my fundament was breaking on retraction to my Creality Hi CFS over and over again. It was driving me nuts. The prints all came out looking great, so I thought I wasn’t having humidity issues and that there was a mechanical problem somewhere. Took the whole damn thing apart to clean and check that everything was tightened to correctly. Multiple times.

    I just needed a filament dryer.

    I had no idea that filament snapping on retraction could be caused by wet filament, and I read about 3D printing a lot more than most. Almost all threads about wet filament are about print quality, and people rarely mention brittleness. Conversely, in threads about filament jams/errors, most comments focus on the mechanical parts (tension, loose screws, debris in the gears, temps, etc.) and rarely mention wet, brittle filament as a possible cause.

    If you’re reading this and don’t have one (or another method for it), get a filament dryer. I recommend the Creality one when it goes on sale as it’s one of the cheapest options that can hit the high temps needed for some filaments and that can also be used as a dry box you can print from. My only gripe is needing to prop the lid open when it’s drying to release the humidity. It’s silly that it can’t dry filament properly without the door cracked open.





  • I’m almost exactly in the same boat, except even at my desk I want wireless. I often turn my camera off and get up to make coffee or go pee in big meetings. It’s great. Even when I’m presenting things, it’s usually only at a specific time, and I can still talk when I’m away from my desk (flip-to-mute microphones are great.)

    I have several sets of wired headphones I used to love. I’d buy several sets at once so I already had a replacement when they inevitably broke But I literally can’t remember the last time I used a pair of wired headphones. I only miss 3.5mm on my phone for plugging into my car’s aux port.






  • Re: your last paragraph:

    I think the future is likely going to be more task-specific, targeted models. I don’t have the research handy, but small, targeted LLMs can outperform massive LLMs at a tiny fraction of the compute costs to both train and run the model, and can be run on much more modest hardware to boot.

    Like, an LLM that is targeted only at:

    • teaching writing and reading skills
    • teaching English writing to English Language Learners
    • writing business emails and documents
    • writing/editing only resumes and cover letters
    • summarizing text
    • summarizing fiction texts
    • writing & analyzing poetry
    • analyzing poetry only (not even writing poetry)
    • a counselor
    • an ADHD counselor
    • a depression counselor

    The more specific the model, the smaller the LLM can be that can do the targeted task (s) “well”.



  • Can’t believe I had to scroll down this far to find this:

    Here’s the gut-punch for the typical living room, however. If you’re sitting the average 2.5 meters away from a 44-inch set, a simple Quad HD (QHD) display already packs more detail than your eye can possibly distinguish. The scientists made it crystal clear: once your setup hits that threshold, any further increase in pixel count, like moving from 4K to an 8K model of the same size and distance, hits the law of diminishing returns because your eye simply can’t detect the added detail.

    On a computer monitor, it’s easily apparent because you’re not sitting 2+ m away, and in a living room, 44" is tiny, by recent standards.
