Rewriting Git history on feature branches


  • feature branch is feature/add_csv_file
  • mainline is deploy

If you want to rewrite Git history on your feature branch here is how to do it.

  1. Make sure you are on the branch you want to rewrite the history of:
name = "mbbx6spp-test";
epoch = 2021;
description = "A test of /proc fs inputs for a Hydra jobset";
inputs = {
uptime = builtins.readFile /proc/uptime;
nixpkgs.url = "github:NixOS/nixpkgs/release-21.05";
outputs = { self, nixpkgs, uptime }: {
checks."x86_64-linux".test = nixpkgs.hello.override { name = "hello-${uptime}"; };
version = {
name = "nixpkgs-21.05-darwin-20210827";
url = "";
rev = "9d6766c0f0b3b03bd63ffc08b2e23e476145719d";
ref = "nixpkgs-21.05-darwin";
jvmOverlay = self: super:
scala = super.scala.override { jre = self.jre_headless; };

A solution to the problem where you want to distinguish identical data payload at both typechecking time and provide a way to inspect that type at runtime via values in TypeScript. Leverages branded parameter types with intersection types.
type Brand<Shared, EventType> = Shared & { readonly __eventType: EventType; };
type SharedCommentEventFields = {
otherField: string;
type CommentFlagged = Brand<SharedCommentEventFields, 'CommentFlagged'>;
type CommentRec = Brand<SharedCommentEventFields, 'CommentRec'>;
const makeCommentFlagEvent = (eventFields: SharedCommentEventFields): CommentFlagged => (

Only shows in UTC because timezones are bullshit and I needed to pick one. Sorry. It is what my servers use.
#!/usr/bin/env bash
main() {
local -ri mar_end=1583042400
local -ri today="$(date +"%s")"
local -r dow="$(date -u +"%a")"
local -r time="$(date -u +"%T")"
local -ri secs=86400
local -ri days_since="$(( ((${today} - ${mar_end}) / ${secs}) + 1 ))"

Fast and loose reasoning as to why Functor and Cofunctor are the same. I have to answer this when coworkers as why Comonads are also Functors and not Cofunctors.
-- Informally showing that Cofunctor is essentially the same structure as Functor thus why Comonads are a Functor which is
-- effectively a Cofunctor.
-- In PureScript Functor is defined here:
-- class Functor (f :: Type -> Type) where
-- map :: forall a b. (a -> b) -> f a -> f b
-- Informally: Making a dual of something is basically flipping the arrows. But to make is easier to see, let's flip the
-- arguments of map in Functor definition since that shouldn't change anything, like so:
const fruits = [ 'apples', 'bananas', 'cantelopes', 'durians', false];
const chunked = _.chunk(fruits, 2); // chunks elements of an arrary
const compacted = _.compact(fruits); // removes falsey values
const filled = _.fill(fruits, 'bananas'); // fill with my favorite fuit
const flattened = _.flatten(chunked); // flatten nested arrays

Accompanying PureScript demonstration of native ADTs for the 'Algebraic Data Types in PureScript':
module Main (main) where
import Data.Unit (Unit)
import Data.Maybe (Maybe (..))
import Effect (Effect)
import Effect.Console (log)
main :: Effect Unit
main = log "hello world"
