100 years is too long time. Modern science don't know, how to make something, which will exist so long. This is because, even when we could make machine which will work so long, nobody could guarantee existence of jurisdiction where ma

It was time of Moore law, and computers grow extremely quickly. I remember, I run 3D Max 2 on 486 with 4mb of RAM in 1996. Models where severe limited, at most few thousands triangles per scene, but it was enough for talents to make crazy t

Nearly all plastic bottles under 10 metric liter are PET (many 10 liters produced from Poly(methyl methacrylate)). PETG is modified PET, so it depend on point of view - (glass semi-full or semi-empty). Any way, in Ukraine people recycle pla

3D FDM printers need much higher bandwidth, because their controller need to make PWM for motors control, and for other things. Yes, one could make 3D printer without PWM, but it will be extremely slow, or even cannot do some things. With m

Just for info, Centronics interface is very slow for 3D printer. It could work (as 2D plotters work), but people make figures faster, and 3D made things even worse.

Working 3D printers existed long time, but only SLS and very expensive. Only in 2000s appear things important for cheap 3D printer: 1. Cheap power semiconductors. 2. Cheap 32-bit microcontrollers. 3. Powerful computers, to run slicer, and f

Nobody said about sanctions after arming Taiwan. It is just your guess. But about sanctions against Huawei, exists juridical cases and official statements. Could you remember any case where US use sanctions without juridical case?

Huawei got sanctions after catch on spy activity. Who else you know?

Looks like model is not trained well. From my exp, after make few projects (2 looks enough), oldest XCode managed to give good suggestions in much more than 50% cases.

It all depends on used technology. DRAM/SRAM really have problems with cosmic rays, but on LEO enough to use ECC, as DRAM refresh it's contents every few milliseconds. In Deep space missions (on Mars and beyond), even hardened ele
