ahknight / symkvs.py
Created January 3, 2014 21:27
Using symlinks as a key-value store. Great for multiprocessing. Sample subclass to keep links to unique files, though there are other uses (considering values only go up to PATH_MAX (usually 1024)).
#!/usr/bin/env python
import os
from errno import *
class SymlinkKVS(object):
def __init__(self, storepath):
self.storepath = storepath
def __delitem__(self, key):

ahknight / searchmail.sh
Created December 30, 2013 18:05
Presuming you keep an archive of your email in a local maildir and presuming you're wise enough to have found mu (it's in homebrew), this script searches for messages and opens up mutt with the results (also in homebrew).
#!/bin/bash
MAILDIR="~/Maildir"
RESULTS="~/Maildir/.SearchResults"
mu find -o links --linksdir="${RESULTS}" --clearlinks $@ && mutt -f "${RESULTS}"

For when you really do know what you're doing...

- (id)objectForKeyedSubscript:(id)key;
@end
@implementation NSString (IndexedAccessors)

Forward calls for a specific delegate protocol to another class for answering.
-(id)forwardingTargetForSelector:(SEL)aSelector
{
// Do we have a scroll view delegate?
if (_scrollViewDelegate && [_scrollViewDelegate conformsToProtocol:@protocol(UIScrollViewDelegate)]) {
// Is this a selector in that protocol?
struct objc_method_description methodDescription = protocol_getMethodDescription(@protocol(UIScrollViewDelegate), aSelector, NO, YES);
if (methodDescription.name != NULL) return _scrollViewDelegate;
}
return [super forwardingTargetForSelector:aSelector];

ahknight / make_ios_icons.sh
Last active December 23, 2015 10:58
Given an input image as the single argument, creates all the files needed for a Universal iOS app (in the same directory, overwriting). Uses pngcrush to compress the images, but that's easily removed/commented out.
#!/bin/bash
function make_icon {
sips -s format png -Z $3 "$1" --out "$2"
pngcrush -ow -q "$2"
}
echo "Using $1 as the base image."
echo "** App Store: iTunesArtwork **"

Public domain. Init with a dictionary, define some properties as dynamic, serve from -valueForUndefinedKey however you wish.
#import <Foundation/Foundation.h>

ahknight / notification-center.py
Created April 25, 2013 15:18
A simple Python script that lets you post to the notification center from the command line without dealing with a full desktop app. Because I can.
