Spaceships

On March 5, 2016 zdr discovered the first c/10 orthogonal spaceship, copperhead.

On March 20, 2016 Simon Ekström found the fireship with a large spark with the copperhead's front end.[1] Tanner Jacobi noticed that two of them can support a tagalong identical to the back end, allowing to stack them.[2]

A Caterloopillar can theoretically be configured to move at c/10, but there are technical difficulties with speeds of the form 4n+2, and as of the end of 2017 this has not been done in practice.

Puffers

The spaceship found by Simon Ekström enabled Nico Brown to construct a c/10 puffer and a rake on the same day.[3]

Guns

A copperhead gun was completed one day after the discovery of the ship.[4]

gollark: Declarative macro-y languages could be parallelized quite well through analyzing their dependency trees.
gollark: Lisps and stuff are actually different.
gollark: Those are fairly C-like with the main difference being better memory management and some level of object orientation.
gollark: What languages are you meaning specifically? There are many not-particularly-C-like ones.
gollark: I think making a less efficient Python program (with intensive mathy things done via numpy etc. which use bindings to C) makes a lot more sense than having a possibly-faster C program which takes several times longer to write, in most cases.
