Created September 18, 2020 07:43
So you have a crawler, but you don't want it to cache images, just the page.
from cachecontrol import CacheControl
from cachecontrol.caches import FileCache
from cachecontrol.heuristics import BaseHeuristic
class NoImagesHeuristic(BaseHeuristic):
def update_headers(self, response):
if response.headers['Content-Type'].startswith("image/"):
return {
'cache-control': 'no-cache',
}

howardjones / MapLoader.cs
Last active July 19, 2019 11:40
A Unity 5 script to load a ZX Spectrum snapshot file of Sandy White's Ant Attack 3D, extract the map, and create it in the current scene. The ANTATTAK resource is a SNA file imported into Unity. 'floor' is a GameObject for each 1x1x1 cube, textured with a stone texture. The loader creates clones of this.
using UnityEngine;
using System.Collections;
public class MapLoader : MonoBehaviour
{
public GameObject floor;
bool IsBitSet (byte b, int pos)

#!/usr/bin/perl
# Cheezy perl script to produce the typeset Unix manual, as ken intended.
#
# Gets a list of every manpage from man(1), and compile them into per-section PDF files in the final/ subdir
# Pulls the intro page to the front of each section, if there is one.
# Also leaves the individual PDF pages in the various man* subdirs
#
# Assumptions: you have groff and ghostscript installed. I think you will need to run makewhatis, too.
