Transitfeed Patch

For the GTFS Explorer project i've been working on, i needed to convert GTFS feeds to KML. Google's transitfeed package is designed to do this, but the latest version (1.2.12) has a bug in it which prevents the KML writer from being imported.

Searching the web on the issue, i found Dylan Vassallo's Github repo pybcp47, which helped me create this patch to squash the bug: transitfeed-1.2.13_unofficial.tar.gz.

To test the KML output online, i used this site.

If the red slayer think he slays,
Or if the slain think he is slain,
They know not well the subtle ways
I keep, and pass, and turn again.

Far or forgot to me is near;
Shadow and sunlight are the same;
The vanished gods to me appear;
And one to me are shame and fame.

They reckon ill who leave me out;
When me they fly, I am the wings;
I am the doubter and the doubt,
I am the hymn the Brahmin sings.

The strong gods pine for my abode,
And pine in vain the sacred Seven;
But thou, meek lover of the good!
Find me, and turn thy back on heaven.

~ Ralph Waldo Emerson, 1857

Apparently Emerson should have titled this poem 'Brahman' instead of 'Brahma'. For why and more insighful commentary, see Emerson's Brahma: An Indian Interpretation, K. R. Chandrasekharan, The New England Quarterly, Vol. 33, No. 4 (Dec., 1960), pp. 506-512.

Why no comments? I used to do public comments but found that moderating and maintaining them took too much time in front of the computer, time better spent playing outdoors. So these days I only do private comments, that is, you can email me comments regarding a post by clicking the 'Comment' link at the bottom of the post.
