    WordPress and Google Analytics external nofollow problem in comment links

    13th February 2009

    Since some WP release, the comment author’s link in comments is broken – it has ‘ external nofollow’ attached straight to the href attribute (which breaks the link).

    I assume that the problem is caused by Google Analytics, namely the “track outgoing clicks” feature (as recalled, might be inaccurate feature name). “Track outgoing links” adds some JavaScript code to all outgoing links, and that script has tick characters like this one ‘ which, incidentally, are also used for delimiting the values of comment anchor tags.

    Git: how to remove file and commit from history

    13th February 2009

    Once I accidentally added circa 300 MiB of archive files to one of my git repositories (which was as small as 5 MiB). I removed those files as soon as I noticed them, but the .git directory still preserved commits with those files, and still occupied over 300 MiB.

    I have found the solution at stackoverflow (see also this question).

    This method worked for me, but I couldn’t push my rebased repository to the gitosis. I would need to re-init the gitosis repository from my rebased, but I’m not yet prepared to do that.

    There is also a slightly different method (which relies on a temporary tag instead of a temporary branch), documented in Git online manual pages; I prefer the temporary branch method.

    Below is a full copy-paste of the winning answer by Charles Bailey:

    # create and check out a temporary branch at the location of the bad merge
    git checkout -b tmpfix

    # remove the incorrectly added file
    git rm somefile.orig

    # commit the amended merge
    git commit –amend

    # go back to the master branch
    git checkout master

    # replant the master branch onto the corrected merge
    git rebase tmpfix

    # delete the temporary branch
    git branch -d tmpfix

    Also, in my case this thread at stackoverflow was highly useful. I start enjoying the concise and compact style of Charles Bailey :) :
