Quickly Render AsciiDoc Notes

AsciiDoc is a great markup format for writing notes. In fact, almost all computer-based notes I write are in AsciiDoc; it is simple yet expressive, portable, and most importantly, grepable.

While Vim is my primary tool for viewing AsciiDoc files, looking through the raw text can leave a bit to be desired. Longing for the beautifully rendered output that only an AsciiDoc file can provide, I threw together the following simple (and ugly) Python script …

Parsing With Parsimonious

Date Tags python

Recently I have been playing around with a parsing library for Python called Parsimonious. So far, I have been very impressed with it. Examples can be a bit hard to find; the following is a simple CSV parser:

from parsimonious.grammar import Grammar
from parsimonious.nodes import NodeVisitor

class EntryParser(NodeVisitor):
    def __init__(self, grammar, text):
        self.entry = {}
        ast = Grammar(grammar).parse(text)
        self.visit(ast)
    def visit_name(self, n, vc):
        self.entry['name'] = n …

Furnace Debugging

A few days ago, the blower motor on my Carrier Weathermaker 9200 furnace stopped working. Luckily, this model of furnace provides quite a bit of debugging information printed on the inside of the door. It was very straightforward to test the blower motor and confirm that it was not the source of the problem. After a bit of poking around with a multimeter, the only remaining possibility was the blower motor relay.
