petersjt014 / sd-aarch64-nilfs.nix
Last active January 18, 2019 22:49
meant to build an aarch64 image with the much flash-friendlier nilfs2 filesystem for root
{ nixpkgs ? <nixpkgs>, system ? "aarch64-linux" } :
let
myisoconfig = { pkgs, config, ...}: {
imports = [
"${nixpkgs}/nixos/modules/installer/cd-dvd/sd-image-aarch64.nix"
];
boot = {
kernelParams = [ "cma=32M" ];

petersjt014 / closure-total-size-MiB.sh
Created December 23, 2018 21:20
finds the total size of a nix closure, taking into account both shared paths and my fear of variables
echo $@ | xargs -I _ bash -c "which _" | xargs -I _ nix-store -qR _ | sort | uniq | xargs -I _ du -sk _ | cut -f1 | paste -sd+ | xargs -I _ bash -c 'bc -l <<< "(_)/1024"'

petersjt014 / IPFS avail script
Last active March 30, 2018 05:24
for finding availibility of ipfs dags
#!/bin/sh
# After taking in an IPFS multihash, this script calculates an 'availability' metric by:
# Traversing the hash's dag to find leaves,
# summing the number of providers per leaf (each rounded down to 10 for performance reasons), and
# returning providers/leaves*10.
# since `ipfs pin add` can be run non-recursively, a peer that advertises a given value
# may not actually posess the entire dag, which can be inconvenient.

see instead the working one here: https://gist.github.com/petersjt014/57debf01da5064f6120616ac983139d0
#!/bin/sh
# this script is mostly just a pile of debug echos and such right now, as recursion within bash still mystifies me
# For testing, the following dag is very lightweight and shouldn't crash anything:
# QmRCJXG7HSmprrYwDrK1GctXHgbV7EYpVcJPQPwevoQuqF
# a diagram of the dag can be found here (or on your local gateway, of course):
