  • You could say the same for a finite element model. A junior engineer with just 4 years of training can solve, explicitly, the deflection at the center of a slender, simple-simple beam of prismatic section and produce an exact (if slightly incorrect) answer. Building a FEM of the same can solve the problem and take longer (to make the model) with similar accuracy, both of which are good enough for design work.

    Only a fool wouldn’t have a FEM around though, as it can solve problem that would take centuries for a human to solve. They may as well make a cartoon with the child digging a 3” hole in beach sand and then showing a backhoe making a jagged edged hole of the same size.










  • The only solution is to fight it and kill it.

    That’s like saying the only way to get out of being hit by flying debris is to eliminate all wind on the planet. As much as we like to think of Threads as some corporate being, it’s not. It’s a hundred million people that are made of meat and have day jobs like you and me - the wind - and a few million bots and controlled accounts which attempt to influence [whatever their master wishes] - the debris. The debris is already here, and it’s people too - just people with nefarious or profiteering intent. It (debris) happens whenever there are enough people (enough wind) to stir things up.

    Cutting yourself off from people is the only way to prevent it because it’s an inherent function of humanity.



  • Nah, the “little” one is a cheapo 43" TCL. FWIW, the big one does full 4K @ 120Hz w/ HDMI VRR (scaled by the set to the 8K panel) with <6ms input lag. I haven’t broken into the ultrawide gaming setting, but I think it just shrinks the 4K space to an U/W (21:9 or 32:9) pixel count given to the OS/GPU so you can game at the game’s “full screen” option into a “smaller” panel. They still refresh at 120Hz.


  • It’s a 2x2 grid of 37" 4K monitors, or a 4x4 grid of 18.5" 1080p displays. It would be more productive if the desk were 3-4" further away and the monitor were 4" below the desk instead of 1.5" above it, as the top 10" or so is impractical to use while sitting except as a status area. OTOH, I welded up the custom mount to my lifting desk, so I can stand and raise the desk so that the keyboard is on the actual desk instead of the tray. In that configuration it maximizes my usability of the screen.





  • My viewing distance is 36" to the center of the screen and the pixel pitch is only 0.66 arc minutes, or about 1.5x the resolution of 20/20 vision. My vision is (corrected) slightly better than 20/20 and I can’t see pixels from where I sit. I can see jaggies in single pixel lines which aren’t dithered (i.e. AutoCAD), but I have to look for them. 8K may be useless for couches, but on a monitor it’s pretty fucking glorious.


  • On the contrary, this is my setup for more than a decade. I’ve tried several mechanicals and haven’t really been pleased with them. I thought the Logitech Master MX would be nice compromise but it wasn’t durable enough, and the lack of tactile feedback made it feel mushy. Oddly, the moderate pitch and short throw (but with the slight actuation resistance) of the Microsoft Designer keyboard is my Goldilocks keyboard. It may not be obvious, but the keyboard “tray” is 3 feet wide - quite a bit bigger than standard. I made it from 1/4" aluminum plate and put it on full extension slides because I couldn’t find a commercial one I liked. It sits right at a neutral wrist position for me (I’m a palm rester) and the mat is a nice 3.5mm neoprene. There’s even a tray heater so my mousing hand doesn’t get cold on long CAD sessions.
