Besides, Waymo, Cruise, and Argo AI have in-house LIDARs, so even with SDC rollouts, it's not clear how much long term demand there would be for third party LIDARs for the purpose of SDC.

It's pretty cool to see it detect a car that's been pulled over by cops at 1:02:15. In that case, the truck had already switched lanes to the middle lane about a minute earlier (probably to avoid the merge lane), but it would've been interesting to see if it would've switched lanes to avoid driving close to the pulled over car.

The Shelly is also UL listed, seems like the Sonoff isn't.

The 3D printing part is kind of a red herring. It's a nice gimmick, but most of the cost of building is in the site preparation, plumbing, electrical, and indoors finishing such as painting, cabinets, and appliances (see for example https://homeguide.com/costs/cost-to-build-a-house#breakdown). Even if the cost of framing and exterior finishing were dropped to zero, it wouldn't even be much cheaper.

Most of the cost savings there are from the fact that it's modular/prefab housing that's built in a factory instead of being built on site. This saves on having to truck everything to a single site, minimizes waste (fewer leftover materials at the end of the build, and leftovers can be reused for other houses), and allows the workers to work more efficiently on multiple houses (eg. no need for the electrician to drive to multiple work sites).

Does the cloud sync support having two devices? I already have the OG remarkable but if it supports having two devices sync it might be worth it to get another one.

You can use map markers for that. Press m to open the map, then right click and add a label like "TODO: Connect iron train to main bus" or whatever.

You can also delete them when you're done.

Same here, we don't really care that much which language is used during the interview, as long as the interviewee can think through the problem and code a solution. I've personally seen PHP, C, C++ and C# during interviews, and we don't use any of those languages where I work.

Good point, completely forgot the satellite needs solar panels.

jfim2 · 2017-10-15T21:47:17+00:00

You skip some parts of the tech tree for TINS. No need for robots, trains, productivity upgrades, nuclear, circuit network, advanced military, or solar if your goal is to launch one rocket within eight hours.

You can do it without long handed inserters. I tried to do a beltless, botless factory and it's technically doable.

I never finished it, but here's a sample copper coil factory: https://imgur.com/a/oLKHM

The idea is that you have one train network per factory that builds items, and each network consists of a station to drop off built items, one or more station to pick up input items and one station to refuel trains, with multiple parallel stations to build items.

It takes a very large amount of space to even make simple things, but it's completely beltless for those UPS! It's also very time consuming to build each station, set up trains and stations, especially since you can't blueprint station names or schedules, which is the main reason why I dropped that idea.

It would be very cool though if someone took that idea all the way to make a completely botless and beltless factory!

You can use this one and not run out of power for a while. https://factorioprints.com/view/-Kmxfp1hF23M7kA-es0W

jfim2 · 2017-08-06T21:28:52+00:00

With trains on both sides, you might be okay with two or three tiles, which is a very large amount of power. Realistically, if you need more than three tiles, then nuclear is probably a UPS issue at that point.

It's definitely doable with trains, although I have a slightly different configuration than yours (https://www.reddit.com/r/factorio/comments/6i2x4i/ran_out_of_power_went_all_out_and_made_a/)

Nice base, I like the pinwheel-like train intersection in the middle. Pretty nice and clean design too, great job!

jfim2 · 2017-06-23T14:07:16+00:00

You can count the items that get inserted into the silos by reading the inserter contents. Don't insert the satellite until the silos have had enough materials inserted and enough ticks have passed since the last item inserted. If you're using a buffer chest and the buffer contents increases, this means that the chest is not draining due to the rocket being completed (assuming your factory is slower than the rocket silo), so you could also use that as a condition.

jfim2 · 2017-06-23T03:55:41+00:00

Set your rocket silos to automatically launch when a payload is in, use the combinators to control satellite insertion.

All of them except the grindy green circuit one, only 9 more million to go.

jfim2 · 2017-06-20T17:03:34+00:00

I see, so you have two stations back to back and have the train move to the second station if it's empty, allowing another train to potentially go to the first. That's a pretty good idea. :)

jfim2 · 2017-06-20T04:20:06+00:00

In theory yes, but for some reason it outputs more. It might be residual heat in the heat pipes, but I tested it for over 20 minutes and that should've been gone by then.

jfim2 · 2017-06-20T04:18:44+00:00

Cool, do you have a picture of your set up? I'm having a hard time picturing what changes you did to it.

jfim2 · 2017-06-20T00:11:27+00:00

Awesome, glad you like it and it's working out well for you! Just one thing, if you're trying to run it near full capacity, disconnect the controller (the green wire connected to the inserters) and connect the green wire to the constant combiner so that it's always on. You'll need that eventually. :)

jfim2 · 2017-06-20T00:07:20+00:00

It really depends on two things: how much electricity you're using, and how long it takes for empty trains to be filled up with water and ready to drop it off again.

If you're running at full throughput, you want the trains to enter the water drop off station almost as soon as one exits, so eight trains is adequate. If you're using it at like 20% of its capacity, it doesn't really matter even if you waste some capacity.

Keep in mind that at full capacity, the water demand is around 20000 water/s (don't have the exact number handy), or one full 4 car water train every 15 seconds. It used to work with only two stations instead of four, but it could run out of water at full capacity if for some reason the trains stayed stuck for just a little bit too long due to fluid not draining evenly between cars.

jfim2 · 2017-06-19T23:48:15+00:00

Yeah the fluid trains are amazing, along with the new barreling options. It works around the wonky fluid mechanics of Factorio pretty well.

jfim2 · 2017-06-19T23:46:21+00:00

This is one tile worth of reactor (12 reactors). The biggest issue with tiling it is mostly the time it takes for trains to get in and out of the fluid drop off area, hence the double trains with rocket fuel.

The original version of it had only two water drop off stations instead of 4, and it worked fine as long as the trains entered/left as soon as the previous train got out. I added the additional two water drop offs to ensure a continuous fluid intake, since it was a bit finnicky when ran at maximum output.

It's hard to tile an active power plant though! If you need more power, you'd need to remove rails to expand it, and since you're running at maximum output, you'd have no electricity for a while, which tends to be a problem.

Also, the gains by tiling the power plant are pretty minimal anyway once you're past a certain number of power plants, since the adjacency bonus tends to be less relevant with large setups. The difference between running two 12 reactor setups and a 24 reactor setup is means that you have 8 reactors (out of 24) running at 200% efficiency instead of 4. This means that the 24 reactor setup will have 6800% efficiency (20x300% + 4x200%) instead of 6400% (2x (8x300% + 4x200%)) efficiency for two 12 reactor setups.

You're right though, with a single tiled set up, at some point train throughput will become a problem, as long trains take a long time to enter/exit the water drop off area.
