Prinzhorn / pre-push
Created November 11, 2013 10:33
pre-push hook to prevent pushing when untracked files are present. i.e. breaking your production server because you forgot to add a new file in your commit and the tests run locally inside the repo.
git status --porcelain | grep '^??'
rc=$?
#grep exits with 0 when a match is found.
if [ $rc = 0 ] ; then
echo "Untracked files present. Aborting push.";
exit 1;
fi

QR code bookmarklet

Just add the snipped as a bookmarklet and instantly turn the current website's URL in a QR code. Very useful when you quickly want to open the page on mobile.

File upload library

I'm currently using https://github.com/blueimp/jQuery-File-Upload, but it's a mess. It does it's job, but the API is...suboptimal.

I took a look at several other solutions, but most of the examples looked like this (which made me cry a little):

$(document).ready(function() {
    $('#some-input').myPlugin({
        option1: 1,
        /*
            A list of thousands of options

Android default browser renders some JPEG images blank.

Well, diffing the output of identify -verbose solved the mystery: The not-working image was saved as CMYK...

MongoDB unique+sparse bug?

From http://docs.mongodb.org/manual/core/indexes/#sparse-indexes

Any document that is missing the field is not indexed.

--

You can combine the sparse index option with the unique indexes option so that mongod will reject documents that have duplicate values for a field, but that ignore documents that do not have the key.
