Composer stuck on installing private GitHub repos

I was trying to install some GitHub repos as dependencies using composer. Composer kept getting stuck on installing the private ones.

composer.json:

    "repositories": [
        {
            "type": "vcs",
            "url": "git@github.com:inderpreet99/private.git"
        }
    ],
    "require-dev": {
        "inderpreet99/private": "1.0.1"
    }

Log:

$ composer install
Loading composer repositories with package information

[Composer\Downloader\TransportException]
The "https://api.github.com/repos/inderpreet99/private" file could not be downloaded (HTTP/1.1 404 Not Found)

install [--prefer-source] [--prefer-dist] [--dry-run] [--dev] [--no-dev] [--no-custom-installers] [--no-autoloader] [--no-scripts] [--no-progress] [--no-suggest] [-v|vv|vvv|--verbose] [-o|--optimize-autoloader] [-a|--classmap-authoritative] [--apcu-autoloader] [--ignore-platform-reqs] [--] []...

Solution:

  1. Go to your GitHub profile.
  2. Under Developer Settings > Personal access tokens, generate a new token.
  3. In cli:
    $ export GITHUB_ACCESS_TOKEN="gibberisheaab78ab18285b9something"
    $ composer config -g github-oauth.github.com $GITHUB_ACCESS_TOKEN
    

Composer should work much more smoothly now.

Webmin bug copying SSL certificates to Virtualmin panel

When you generate a SSL certificate for an nginx site through the Virtualmin interface for a virtual (sub-)server, the button “Copy to Webmin” incorrectly triggers the “Copy to Usermin” feature.

On the other hand, the Webmin interface to generate the SSL certificate also fails, because it does not allow for generation for nginx hosts (only Apache hosts).

Trick:

  1. Generate the SSL certificate using Let’s Encrypt in Virtualmin for the virtual (sub-)server.
  2. Run the following command as root to copy the certificate to Webmin:
    virtualmin install-service-cert --domain yourdomain.com --service webmin

Unrar split RARs on Windows using Cygwin

Sometimes out of dire circumstances one may download a huge set of rars. Unraring all the scene release files in split rar format in each separate directory with their separate subtitles (idx/sub files) is a cumbersome task.

  1. Install unrar from http://gnuwin32.sourceforge.net/packages/unrar.htm
  2. cd into the base season directory using cygwin.
  3. Unrar recursively:
    find /path/to/dir-of-rars -iname "*.rar" -exec sh -c 'dir=`dirname {}` && echo "$dir" && unrar -o- e "{}" $dir' \;
  4. You may need to run this multiple times to catch the rars that the rars may create.

Avoid email submission on SHOUTcast DNAS download

SHOUTcast makes you submit a valid email each time you want to download SHOUTcast DNAS or DSP. I’ve put links below that let you to download x86 (32-bit) and x64 (64-bit) straight without nag screens. These links will not get outdated because they always point to the latest.

Linux x64 link

Windows, BSD, Mac OSX, ARM and DSP links can also be found in the parent directory index.

Things learned from Wordcamp 2012

I attended most of the developer track presentations at Boston’s Wordcamp 2012. I learned about some interesting tools and techniques that I’d like to document for myself and others.

Talk Optimizing for Speed by Ben Metcalfe

  1. YouGetSignal’s Reverse IP Lookup – Shows you how many other hosts live on the same IP Address. This can be helpful for anyone using shared hosting or maybe VPS.
  2. Debug Bar – Get debugging information from each page WordPress page load.
  3. Google XML Sitemaps – Delete this plugin if you have it. (I had it.)
  4. YSlow – Get load times and optimization tips of a page request.

WordPress as a Web Framework by Sam Hotchkiss

  1. MVC frameworks for WordPress
    1. WP MVC – Provides a singleton object and eliminates the metadata bottleneck by providing tables indexed by post IDs.
    2. Tina MVC
  2. _s Theme – Use Automattic’s Blank Theme as a good starting point.

Automating frontend workflow by Aaron Jorbin (blog post, slides)

  1. Autojump – Jump to frequently used directories
  2. Commander.js (nodejs) – Script working with CLI
  3. watch (nodejs) – Watch files/dirs
  4. mockjax – Fake your ajax calls (good for protyping or testing un-related, yet dependent functionality)
  5. Travis CI – continuous integration service (wordpress plugin tests)
  6. Glue – generate css sprites

Microdata for SEO by Dave Ross

  1. Add itemprop, itemscope, etc to any identifiable schema
  2. Google Rich Snippets Tool – Test your microdata
  3. Examples: SiteNavigation element for navigation, Blog element for blog posts, etc
  4. Some quick tidbits: Bing rates sites with microdata higher than sites without, and Google uses the microdata in search results

Enterprise WordPress by Jake Goldman (1up)

  1. Sites to show clients: showcase, WordPress VIP
  2. Maintaining a beautiful WordPress admin

Shortcodes by Jon Bishop

  1. Use oembed rather than plugins to support embedding media from sites like youtube, facebook, etc

Codex by Erick Hitler

  1. Use santize_* functions to save to db: santize_text_field(), sanitize_title()
  2. Use esc_* functions to show data to user (esc_url_raw() is the exception, it is the opposite of esc_url())

Javascript hooks by Luke Gedeon (1up)

  1. Javascript custom events are coming, they will provide functionality similar to WordPress’ action and filter hooks (list of hooks)

Command line python script to get context lines on a search string

grep -B and -B flags don’t work when grep is used on the command line with readline support. So I created this little script that does work on the command line. use -h flag to learn. Here’s how I’ve used it:

ls -al | ./printcontext.py -b 1 -a 1 -d test.txt

This finds the test.txt file and prints the 2 files around it.

Include admin scripts/styles in WordPress plugin

There are two ways of including custom scripts/styles in an admin page for a WordPress 3 plugin.

Solution 1 (Deprecated):


$slug = add_submenu_page('myplugin.php', 'My Plugin', 'My Plugin', 'upload_files', __FILE__, 'myplugin_options');

add_action('admin_print_scripts-'. $slug, 'myplugin_enqueue_admin_scripts');
add_action('admin_print_styles-'. $slug, 'myplugin_enqueue_admin_styles');

function myplugin_enqueue_admin_scripts($suffix) {
	$plugin_path = plugin_dir_url(__FILE__) . 'resources/';
	wp_enqueue_script('jquery.js', $plugin_path . 'jquery.pack.js');
}

function myplugin_enqueue_admin_styles($suffix) {
	$plugin_path = plugin_dir_url(__FILE__) . 'resources/';
	wp_enqueue_style('jquery.css', $plugin_path . 'jquery.css');
}

Solution 2 (recommended):

$slug = add_submenu_page('myplugin.php', 'My Plugin', 'My Plugin', 'upload_files', __FILE__, 'myplugin_options');

add_action('admin_enqueue_scripts', 'myplugin_enqueue_admin_scripts');


function myplugin_enqueue_admin_scripts($hook_suffix) {
	if ($hook_suffix == 'myplugin/slug') {
		$plugin_path = plugin_dir_url(__FILE__) . 'resources/';
		wp_enqueue_script('jquery.js', $plugin_path . 'jquery.pack.js');
		wp_enqueue_style('jquery.css', $plugin_path . 'jquery.css');
	}
}
