chendo / test_helper.rb
Created November 27, 2013 02:29
I wrote a helper that helps one debug `rand`-based test failures by running `srand` with the same number before every test. That way, if a test fails in a full run due to a `rand` issue, by using the same `--seed`, it should fail whether you run just the file or the individual test.
class ConsistentRandomness
def self.setup_rng
if !@seed
@seed = srand(1)
puts "Using seed #{@seed} for every test"
end
srand(@seed)
end

A ComputerCraft script that lets you wirelessly request items into an Ender Chest attached to the ME bridge. Requires a MiscPeripheral Chat Box (by default on the left), a ME Bridge (on the bottom), and then you define where players chests are in relation to the ME Bridge. To use, say `give <item id/meta> <amount>`. The script has it capped to 6…
local cb = peripheral.wrap('left')
local me = peripheral.wrap('bottom')
local chestMapping = {}
function getUuid(id,meta)
return id + meta * 32768
end
chestMapping['_chendo_'] = 0 -- down

This lldb script lets you selectively ignore Obj-C exceptions. See http://chen.do/blog/2013/09/30/selectively-ignoring-objective-c-exceptions-in-xcode/
import lldb

import shlex
# This script allows Xcode to selectively ignore Obj-C exceptions
# based on any selector on the NSException instance

Bundler CDN benchmarking with Fastly and Cloudflare (without HTTPS). The version on Cloudflare won't match the rubygems.org exactly as I can only take a snapshot, but the file size will be similar.

My first assembly! Wrote a bootloader that just prints gibberish in colours. I tried to slow it down but couldn't figure out the interrupt handler stuff.
