The extra bit of the lid houses the antennas, it's plastic to not interfere with the signals as much as the magnesium would have. I do wish they could have attached it better or made the whole lid plastic over a magnesium frame or something.

This isn't a group looking to make a potentially one-off product in an attempt to break into the industry. This is a different marketing and manufacturing model that is trying to mini-max the cost-to-quality ratio by only making products that have already sold. Similar production quality as other selvedge denim companies like APC or Iron Heart, and sewn in the US. The fabric they source is often of limited supply, either discontinued or small production runs, from high quality mills.

Yeah it helps if it is properly formatted and intended to be easy to read. Style takes effort. A lot of us let emacs handle the formatting - auto indent and something like paredit to move lists around. Once you get a feel for how the tools move things it is a bit easier to predict, but even then it takes someone putting in effort to make it maximally readable.

The game has an alpha version appropriately named save_breaker that gets regular if not daily updates. Some of the later puzzles are completely different, the second architecture has been replaced with a more advanced one that includes pipelining, and some new puzzles are still in the works. The new assembler is much more modular and many of the components have changed shape, with some having been removed or combined. The author plans to release it as v1 when stable but who knows when that will be. Breaking changes still occur occasionally.

The top of fig 3 doesn't accurately represent a string pulled down in the middle. A string pulled down in the middle would have no curve to it in the legs unless some force is acting on it, it would look like a V.

Qubes is a Linux OS. It's like if you took Fedora and installed xen on it and booted up some VMs and the windows for them opened within the base OS instead of in individual system windows. Plus some cool magic with the file system to reduce redundancy and how many times you have to update things.

Yeah in emacs with paredit/smartparens/parinfer or whatever, it is both text and structure. With parinfer you change the text and the structure gets modified to match. With the other two you can change the structure directly with a command that has a silly but descriptive name like slurp or barf.

Ah this might be an in-industry definitions thing[1], I was taught most anything thin, especially the pieces that are welded to the unibody, are panels. Not just the outer skin. So floor pan, pillars, trunk panels, roof, subframe, maybe control arms, etc are all panels. Basically anything stamped out of sheet metal. It is the way they're often constructed that leads to corrosion, thin pieces of metal in close parallel proximity are especially hard to clean. Think two flat pieces spot welded together one on top of one another as many seams are. I'm sure capillary action doesn't help those either. They'd have to be sealed in paint or epoxy entirely to avoid the seam corroding. Welding itself changes the structure of the steel and leads to corrosion near the weld. If not spot welded, a different steel might be used for the weld that has higher strength to compensate for welds weakening the steel - but to get that they trade-off higher carbon content, making it more prone to corrosion.

There are very few all-aluminum cars. Audi A8 was for a while and might still be. I am not aware of anything cheaper.

Most injection systems are rated for 20% bio aka b20 without voiding the warrantee. Bio beyond that doesn't have enough lubrication so you have to supplement it with a splash of something like 2-stroke oil. It can run for a long time like that without hurting the pump but manufacturers don't support it. Some gas stations sell b20. If you're talking straight veg you need a certain type of injection system for reliability, and even there you're decreasing the life of the pump. Old mechanical pumps work great, first gen cummins, vw 1.6, mercedes om617 machines can run on straight heated veg for a long time with no issues. Electronically controlled mechanical systems like the vw 1.9 tdi can run on it too but might be a bit more finicky about what you're injecting.

Assuming you want to make your own bio you'd have to set up a transesterification process where you convert the trans fats out of the oil, that process uses lye so it needs a decent container and is best automated. If you're trying to recover the solvent, which is probably methanol, you'd need a still as well, and decent ventilation. Fully automated with raspi or arduino components is a couple grand or more, prefab units run something like 10k.

If rather than bio you're talking straight grease, it is cheaper to clean but more expensive to set up the car. You'd need a second fuel tank, preferably heated depending on climate, some solenoid valves, and a heated fuel filter. And a pile of hoses and wires to connect it all. Maybe a grand or so to set it up depending on driving conditions, kits run 1-2, some are better designed than others.

Either way you'd also want some big drums for holding tanks at home where you can let the fluid layers separate and a pump to move them around. Most car washes give away polyethylene 50gal barrels.

Most expensive thing in my opinion, is your time and the cost of the oil. You can get something like 5-50gal per week per restaurant, tho most overuse the oil. Best places don't cook meats in there at all. Chain and large restaurants want a schedule. Cost of the oil varies, used to be paid to take it, somewhere around 2010 that inverted and now you pay for the oil.

Labor times are for new cars at flat rate dealerships, a lot of them are not realistic. Dealers make a pile of money off brake jobs, shocks, and other "gravy" repairs where it takes less time than the book says. They also lose time on the hard stuff that nobody in the place does on a routine basis like wire harness repairs. The timing also expects the mechanic to have the right tools all at hand, the right parts all ready to go, and the car is expected to be new, clean, and rust free. Your mileage may vary.
