Bash script to run a benchmark under decent conditons.
#!/bin/bash

# Usage: runperf ./my-benchmark-binary

# Script to run a benchmark / performance test in decent conditions. Based on:

# - "Performance Analysis and Tuning on Modern CPU" by Denis Bakhvalov, Appendix A.

# Note that this doesn't do any actual benchmarking, your binary must be able to do that all by itself.

How to setup a Factorio Headless Server

[LINUX] Factorio Headless Server Guide

So, with credit to the Factorio wiki and cbednarski's helpful gist, I managed to eventually setup a Factorio headless server. Although, I thought the process could be nailed down/simplified to be a bit more 'tutorialised' and also to document how I got it all working for my future records.

The specific distro/version I'm using for this guide being Ubuntu Server 16.04.1 LTS. Although, that shouldn't matter, as long as your distro supports systemd (just for this guide, not a Factorio headless requirement, although most distros use it as standard now). The version of Factorio I shall be using is 0.14.20, although should work for any version of Factorio 0.14.12 and higher.

Just a note to newcomers: If there are any issues with the installation steps, people in the comments are doing a good job

Elm Json.Decode tutorial and cheatsheet

When receiving JSON data from other resources(server API etc), we need Json.Decode to convert the JSON values into Elm values. This gist let you quickly learn how to do that.

I like to follow working example code so this is how the boilerplate will look like:

import Graphics.Element exposing (Element, show)
import Task exposing (Task, andThen)
import Json.Decode exposing (Decoder, int, string, object3, (:=))

import Http

Elm Destructuring (or Pattern Matching) cheatsheet

Should be work with 0.18

Destructuring(or pattern matching) is a way used to extract data from a data structure(tuple, list, record) that mirros the construction. Compare to other languages, Elm support much less destructuring but let's see what it got !

Tuple

myTuple = ("A", "B", "C")
myNestedTuple = ("A", "B", "C", ("X", "Y", "Z"))

Auto-deploying built products to gh-pages with Travis

Auto-deploying built products to gh-pages with GitHub Actions

This is a set up for projects which want to check in only their source files, but have their gh-pages branch automatically updated with some compiled output every time they push.

A file below this one contains the steps for doing this with Travis CI. However, these days I recommend GitHub Actions, for the following reasons:

  • It is much easier and requires less steps, because you are already authenticated with GitHub, so you don't need to share secret keys across services like you do when coordinate Travis CI and GitHub.
  • It is free, with no quotas.
  • Anecdotally, builds are much faster with GitHub Actions than with Travis CI, especially in terms of time spent waiting for a builder.

Better local require() paths for Node.js

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

Possible solutions
