    NPM and Yeoman update/install notes for MacOS 

    Had to deal with some issues introduced by bad homebrew installations and possible old NPM installs. My guess is that I probably cheated/screwed up using a sudo install when I should have done something different.

    This all started playing with the WebDevStudions WordPress plugin generator for yeoman.

    Get a Plugin Kickstart with Yeoman & generator-plugin-wp!

    This gist was very helpful – Fixing npm On Mac OS X for Homebrew Users


    Another strange issue was caused by installing the generator-plugin-wp yoeman generator on a broken yeoman/npm system. This posted github issue helped. https://github.com/npm/npm/issues/10995 This needed a straightforward uninstall, cache clear, and reinstall. I may have reintialized my terminal sessions to drop out of sudo mode. It looked something like:

    $ sudo npm remove -g yo generator-plugin-wp
    $ npm cache clean
    -- can't remember if I relaunched terminal to drop out of sudo mode.
    $ npm install -g generator-plugin-wp

    I’ll be testing this yeoman generator on the side for a while: https://github.com/WebDevStudios/generator-plugin-wp

    Spying on a directory with auditd 

    Files start coming up missing for me on a server and I get freaked out looking for security holes, but sometimes users and other utilities are spiking the bunch bowl. You can get serious with watching files with other utilities, but I went back to good ole auditd.

    A simple test to track stuff getting trashed from an upload folder:

    auditctl -w /site-dir/wp-content/uploads/ -p wa -k upload_issue

    A capital W will remove the rule:

    auditctl -W /site-dir/wp-content/uploads/ -p wa -k upload_issue

    Do a quick search for issues with ausearch.

    ausearch -f wp-content/uploads

    Now permanently add the rule on a redhat system by putting this line in /etc/audit/audit.rules. Just leave off the auditctl command.

     -w /site-dir/wp-content/uploads/ -p wa -k upload_issue

    Of course you need to make sure your auditd process is running and using chkconfig, etc. Good ole check status like:

    /etc/init.d/auditd status

    Here are a few of the resources I used:

    Please forgive the RedHat auth-walls…

    My Favorite Httrack commands 

    HTTrack is a website mirroring utility that can swamp your disks with mirror copies of the internet. I’ve had to use it several times to make off-line copies of websites for all sorts of weird reasons. You’ll find HTTrack at: http://www.httrack.com. You can get a full list of command line options at: https://www.httrack.com/html/fcguide.html. There is a spiffy web and Windows wizard interface for HTTrack, but I gave that up.

    This is the recipe for the command line options I’ve been using to produce a browse-able offline version of accreditation documents. This command says “Make an offline mirror of these URLs, go up to 8 links deep on these sites and 2 links deep on other domains. Stay on the TLD (.edu) and do it as quickly as possible. Be warned as it currently stands this will fill up about 1.5GB of disk space ;P.

    httrack http://www.nicholls.edu/sacscoc-2016/ http://www.nicholls.edu/catalog/2014-2015/html/ http://www.nicholls.edu/about/ -O /Users/nichweb/web-test -r8 -%e1 -%c16 -*c16 -B -l -%P -A200000

    The great part is that the archive grows as URLs are added.

    Apache log one-liners using tail, awk, sort, etc. 

    Good bunch of samples with other examples found at: https://blog.nexcess.net/2011/01/21/one-liners-for-apache-log-files/

    Using HyperDB to separate and share user and user_meta between WordPress installations 

    I need to remember to keep this example for some testing. This should be a good start for sharing a user and user_meta between websites. I do know that user_meta tends to have very site-centric settings at times. Original article was located at: http://wordpress.aspcode.net/view/63538464303732726666099/how-to-use-hyperdb-to-separate-and-share-a-user-dataset-between-wordpress-installs

    $wpdb->add_database(array( //Connect to Users Database
        'host'     => DB_HOST, // I am using the same host for my two DBs
        'user'     => DB_USER, // I am using the same username for my two DBs
        'password' => DB_PASSWORD, // I am using the same p/w for my two DBs
        'name'     => 'my_user_db_name', 
        'write'    => 0, // Change to 1 if you want your slave site's the power to update user data.
        'read'     => 1,
        'dataset'  => 'user',
        'timeout'  => 0.2,
    $wpdb->add_database(array( // Main Database
        'host'     => DB_HOST,
        'user'     => DB_USER,
        'password' => DB_PASSWORD,
        'name'     => DB_NAME,
    function user_callback($query, $wpdb) {
        if ( $wpdb->base_prefix . 'users' == $wpdb->table || $wpdb->base_prefix . 'user_meta' == $wpdb->table) {
            return 'user';

    Create a new Git repo from and old repo 

    How to extend an old repository as a full copy in a new repository. This preserves the history of the old repository. Future changes will not affect the old repository, but will be committed to the new repository.

    This originally came from the info found at: http://stackoverflow.com/questions/10963878/how-do-you-fork-your-own-project-on-github

    // This makes the new repo as a checkout of the old repo to a new directory.
    # git clone https://github.com/nicholls-state-university/nicholls-2012-core.git nicholls-2015-core
    // Change directory to new repo area
    # cd nicholls-2015-core
    // Change the origin to the new repo. Remember to make the new repo area.
    # git remote set-url origin https://github.com/nicholls-state-university/nicholls-2015-core.git
    // Push commits to new area.
    # git push origin master
    // Push all changes to repo, just making sure.
    # git push --all

    Git local repositories 

    These are some quick examples and notes related to using git with local repositories. Using local repositories can be helpful maintaining file changes without committing to larger repository systems like Github. Instead of syncing with a remote repository, synchronization and changes are committed to the local repository and recorded.

    First we create a new local folder and initialize it as blank Git repository.

    # mkdir my-local-git
    # cd my-local-git
    # git init —bare

    Then we just clone that to the location we want and work on it like any other git repository.

    # git clone /where/is/my-local-git

    OSX turn off or delay hibernate 

    Apple’s Mac OSX hibernate can be delayed indefinitely or turned off by issuing this terminal command.

    sudo pmset -a hibernatemode 0

    To get back to default normal hibernate mode type this terminal command.

    sudo pmset -a hibernatemode 3

    So the word is this won’t disable hibernate on battery failures. Haven’t tested, hope I won’t have to.

    Git subproject notes 

    I want  to use a project as a tool-set for a big ole work project. The sub-project isn’t mine, I don’t have access to the code, I will probably need to update it as a component of my big project.

    Some good reading here: https://hpc.uni.lu/blog/2014/understanding-git-subtree/

    Some of my first tip-toe basic understanding.

    # Straight subtree pulls the dependency into local directory
    git subtree add --prefix CMB2 https://github.com/WebDevStudios/Custom-Metaboxes-and-Fields-for-WordPress.git master --squash

    Apparently this can get better if you use the

    git remote[\code] command.
    # Setup dependency as a remote
    git remote add -f Custom-Metaboxes-and-Fields-for-WordPress https://github.com/WebDevStudios/CMB2.git
    # Fetch information about remote
    git fetch Custom-Metaboxes-and-Fields-for-WordPress master
    # Add remote to subdirectory and pull master branch
    git subtree add --prefix=CMB2 --squash CMB2/master
    # Update remote down into local directory
    git subtree pull --prefix CMB2 CMB2 master --squash

    With the remote added we should be able to update the dependency project by doing a subtree pull. Remember the sub-project is not mine but it will need updating.

    git subtree pull --prefix Custom-Metaboxes-and-Fields-for-WordPress Custom-Metaboxes-and-Fields-for-WordPress master --squash

    Tags: CSS, HTML, Image Sprites, Images, , SVG   

    Let's do SVG sprites and fun 

    So this currently only works in Firefox for me.


    Alright! So a big part of the issue is that you might want to think about SVG differently. SVG is a markup document format with different features than your standard pixel based image format.
