Anyone who has tried car/van camping in public should be familiar with this feeling. While sleeping in my van I've had plenty of nightmares where the nearest neighborhood forms an angry mob to have my vehicle towed away.
You can thank Grover Norquist[1] for that. The Taxpayer Protection Pledge [2] that he promulgates to US republican lawmakers is the primary mechanism though which those legislators justify blocking simplification and streamlining of tax filing. If it's easier for people to pay taxes the government will probably ask for more cash if we implement those systems, right? Therefore it must be blocked according to the pledge! The logic is airtight!
Ironically in reality this is actually pretty much the opposite of taxpayer protection and amounts to additional tax paid to private corporations on TOP of our existing taxes.
"It might be possible to embed a C compiler into a PDF by compiling it to JS with Emscripten, for example, but then your C compiler has to take input through a plain-text form field and spit its output back through a form field."
"Passengers were not allowed to leave the airplane because the Goose Bay Airport did not have a customs officer on duty during the overnight hours. Saturday bled into Sunday, and still the flight remained grounded."
Look at their product lines--Spot and Handle are the furthest things from humanoid. They've also done some static robot arms.
Atlas is their only active humanoid platform, which they've stated is mainly a research platform just for the sake of advancing robotics and pushing the limits.
Throughout the 1800s there were tens of thousands of homeless kids just running around New York City making ends meet. The data is unreliable but it’s interesting to wonder how their lives turned out.
Consider that the tunnels will encourage economic activity, which will encourage population growth at the nodes. I've always felt that the North American method of building transit between 'natural' urban centers is wrong, and that the Japanese have it right--demolish everything, build a rail line, and economic life will flourish around the nodes.
Yes, mostly in house except for specialty materials, high labor components, etc, similar to the workflow at many small hardware firms with machine shops. We just had more combustion involved than your average hardware company.
The compact dimension of the demonstrator engines make that kind of agile development possible--similar to the idea behind Boom's scale demonstrator.
It was just like any startup really, a great team of really smart and dedicated folks trying to disrupt an entrenched industry using new ideas. Lots of simulation, lots of practical prototyping, lots of test rig time. We spent so, so many hours in test chambers observing how a particular engine type behaved with incremental changes to its design, changes which were backed up by simulation. The resulting data was used to strengthen the simulation and we repeated this loop many times. The challenge with this is that there are seemingly infinite different parameters to observe and control in each loop in both the physical and simulated engines, which must be done with high fidelity to learn things.
My understanding of thermodynamics was routinely humbled by my coworkers. I remember one time rolling into the office in the morning to find my coworker twirling with excitement and saying something like "I had a realization at 3AM and came to the office and figured out my enthalpy problem!"
Working with your buddies to create a working engine from scratch that is unlike any engine that has ever been created before it is a real rush. I recommend it for anyone.
Here's a slo-mo video of combustion inside an LP engine. We bolted a thick piece of quartz onto the engine instead of one of the side pieces. https://vimeo.com/111796558
Ditto, I am also interested on any input from others who have dabbled in the field that OP mentions. Being from the Northeastern United States, I have always just picked up base layers of various thickness from L.L. Bean, like this: https://global.llbean.com/shop/Long-Underwear-Base-Layers/51...
I don't think of this as a technology or expensive, though. They are somewhat pricey, but can be worn for many winters and thus have good value.
I frequently just use any hotel, not necessarily one I have a reservation with. Between tipping, having frequent traveler status, and dressing nicely I’ve never had a problem.
MSP airport is one of the few places I’ve seen coin lockers in America.
