LEGO molds are some of the best in general manufacturing. If a 3d printer could make a LEGO brick as good as the original it would imply that you could print virtually any plastic part to sufficient tolerance.

This - 100%. I just need to edit config files and write some simple code. I do a lot with single board ARM computers and something nice and light weight is perfect.
Some of the new NAS boxes are using Baytrail laptop chips that are much faster than the old single core Atoms. I don't know about real-time HD transcoding but they rip through par2 and unrar calculations. I think the GPU is still enabled, even on a NAS, in case GPU transcoding is an option.
Baytrail MBs are a great option if you want to "roll your own" server. ~10 watts of power before hard drives.
My first D54250WYKH couldn't even get through the OS install. It had IO errors that were unrecoverable every time. The second NUC would consistently take a Kubuntu install but has intermittent kernel panics and reboots for seemingly no reason. And it near bricks using any kind of suspend mode in Linux - everyone is having that problem. You have to disassemble the whole NUC and pull the CMOS battery to get it to boot after any sort of suspend. Suspend is pretty important because these small cases use small, loud fans. Just a modern desktop, an idling modern desktop, is enough load on the GPU to throttle up the fan to full RPM.
I posted about my troubles on the NUC forums, along with many others. Intel says they don't officially support Linux so it's on you to fix. That's interesting because they sell the NUC with no OS. If it's intended to be windows only they should sell it with windows. Also in the firmware notes they talk about fixing a bug that was effecting Openelec, so obviously Linux is part of their testing.
Asheron's Call (the first one) was great. I really wish they hadn't wasted so much the time and so many resources on a sequel. AC had a good loot system, crafting, genuinely novel lore, real PKing, a full open world, in game guilds, in world housing, a functioning economy (ok sometimes money was worthless). I moved onto to WoW and it was much more polished but didn't have that wide-open, it's your world feel of AC. WoW felt like running around Disneyland. You could get lost in AC.
You haven't lived until you've done a Chakron's quest (including the run through the Direlands) or the Aerfalle quest to get your recall scroll. Morningthaw server here. Crowning achievement? Trading for one of the rare sets of PPGSA. That and getting a villa... good times
More specifically the symbiotic bacteria that they host. Nature has solved this problem already (and more than once) - no high pressures or temperatures needed.
This. The Statue of Liberty is made out of copper (at least the skin) and is over 100 years old. Notice how it crumbles into powder? Oh wait. It doesn't...
Celeron J1800 and J1900 boards are passively cooled, low power and cheap. Consider them as an alternative to a NUC
I bought this board:
It's more expensive than the ASUS, Gigabyte, etc J1800 boards but mine does 12V dc-dc conversion on board and has many more SATA connections. That sames me a traditional PSU and SATA card/expander.
I built a baytrail server and its amazing for the cost and power budget. The Intel HD graphics aren't for gaming but it can serve and render media on a sip of power. The HDDs are by far the biggest power hog. I struggled with these ARM chips and their custom distros enough. The ability to be on x86 with well supported peripherals is well worth it - gpu especially. Need to run some wintel stuff now and again? Virtualbox works fine. On the other hand ARM chips always have their issues with proprietary gpus and their binary blob drivers rife with kernel compatibility problems. And you find yourself stuck in a back alley of "mostly" compatible software and patches.
You might hate sucking up to Intel but at least the drivers work. I might be burning 7 watts instead of 5 but that's nothing in the overall power budget. And baytrail is much much faster than IMX6.
I wasn't sure how many nines but as you point out, you need a lot! Calculating those 9s ahead of time at various temperatures certainly dips into analog.
Totally true. A for effort!
But I'll say FPGAs are a niche technology. Many products have no FPGAs and effectively none have only an FPGA and no supporting circuits. Commonly FPGAs are used for ultra high bandwidth applications where a traditional microprocessor can't hang. All those high bandwidth buses and external I/O interfaces press right up against analog. Maybe you are using a stock dev board and programming the FPGA over USB. So congratulations - your analog issues have been abstracted away but someone made the dev board, and when your design doesn't work you'll be pulling out a o-scope that costs more than a car to debug. And I some point I promise you'll be analog scoping waveforms.
For brevity I didn't mention your follow on but it is especially true. If you aren't worried about analog you aren't pushing your digital design hard enough. And a lot of design happens at the bleeding edge of engineering where you have to push hard.
Part of "Digital", the lowest level of digital, is a contract concerning how signalling between transistors occurs. This includes timing, rise and hold times, voltage thresholds and current. I'll include avoidance of race conditions, clock distribution, refresh cycles on DRAM and temperature effects as a side car. These are all design constraints that make sure the 1s and 0s working properly. It's only when you have a 99.99999999% solid digital contract that you can begin the digital side of the design.
All of this digital design is solidly analog and will NEVER go away.
I could make another whole post about the absurdity of traditional "analog" going away. All these mobile devices have some amazing RF design going on from the antenna down to the mixed signal SoC. Analog is everywhere and at the core of every electronic gadget.
Tesla is traded on Wall Street and they raised the money for the gigafactory from Wall Street through a convertible bond sale. Wall Street has been key to providing capital to Tesla.
Comments about mechanical simplicity are missing the key advantage. There is no risk of pre-ignition bending a piston rod if if fuel is introduced too early in the cycle. Direct injection also solves this - there is not fuel in the cylinder until it's safe. This is the solution for diesel engines and allows for higher compression. But a crankshaft makes it hard to change an engine's compression ratio, which can be useful, especially in a multi-fuel setup. A crankshaft dictates how far the piston can rise towards the cylinder head and determines a fixed volume at top-dead-center, the highest point in the piston's travel. In a free piston engine the piston is free to top out closer or farther from the cylinder head.
