One trick is to resize the game window into a square. Zoom is limited by your longest screen dimension.

You need a third entity whose only purpose is to appear in blueprints.

Try setting line_length = 6.

You need to change the type to something with item slots. I recommend "car", since the inventory can be filtered to blueprints only.

Set filename = "__core__/graphics/empty.png"

The wiki formula does match what you are saying, though the math symbols make it hard to understand.

The topless brackets mean "round down to the nearest integer".

Adding a random number between 0-1 to extra_fraction and then rounding down, is the same as rolling a random number against extra ...

I added the deactivated-Space-Age recipe to the info box.

I suspect it's because the C++ code is written in CamelCase (see the internal class names here), and they want an easy way to keep the lua functions distinct.

This worked for me.

local entity = table.deepcopy(data.raw['lane-splitter']['lane-splitter'])
entity.name = "my-splitter"
entity.hidden = false
data:extend{entity}

local item = table.deepcopy(data.raw['item']['lane-splitter'])
item.name = "my-splitter"
item.subgroup = "belt"
item.place_result ...

Try setting item.hidden = false.

Not easily.

An advanced trick would be to daisy chain 3 entities, big mining drill -> assembling machine -> inserter. Then add the supporting control.lua code to set that up every time a mining drill is built.

Expected resources is the output (in fluid per second) of a normal pumpjack with no bonuses at all.

You will have to multiply all your bonuses to that in an arithmetic combinator if you want it to match what you have.

In your case the calculation is:
459 (pumpjack signal) * (1 + 100/100 speed ...

An easy way is to modify the terrain to collide with biter spawners. Obviously this only works for areas that you can give special terrain.

300 km/s using only basic components.

You can buy the DLC and disable the "Space Age Mod" to get elevated rails, recycling, quality, and nothing else.

Foundry is locked behind the Space Age Mod.

:: is just a separator between the name and type of the variable. This is a factorio.com convention, it is not a standard usage in any programming language.

If an item does not allow productivity, you get one stack per rocket.

If an item does allow productivity, the rocket weight is the weight of all its ingredients.

You can override this by setting ItemPrototype.weight . In your case you would want to set:
data.raw['item-with-entity-data ...
