As long as Mage_Core_Controller_Varien_Action is a parent in your controller’s hierchy, you are good to go (it probably is).  This class has a const FLAG_NO_START_SESSION which looks promising. Digging into the code a little we see that it controls whether cookies are processed or the session is started:

<?php
...
        if (!$this->getFlag('', self::FLAG_NO_START_SESSION)) {
            $checkCookie = in_array($this->getRequest()->getActionName(), $this->_cookieCheckActions);
            $checkCookie = $checkCookie && !$this->getRequest()->getParam('nocookie', false);
            $cookies = Mage::getSingleton('core/cookie')->get();
            if ($checkCookie && empty($cookies)) {
                $this->setFlag('', self::FLAG_NO_COOKIES_REDIRECT, true);
            }
            Mage::getSingleton('core/session', array('name' => $this->_sessionNamespace))->start();
        }

By adding to the preDispatch() method of our Action or Controller we can toggle this:

<?php
class Ai_AjaxCatalog_Controller_Action extends Mage_Core_Controller_Front_Action
{
	public function preDispatch()
	{
		$this->setFlag('', self::FLAG_NO_START_SESSION, 1); // Do not start standard session
		parent::preDispatch();
		return $this;
	}
}

Now, any action in this controller will be stateless and not effect any sessions.

For firefox and chrome we now have the JiraTabs bookmark button.

Drag this link up to your bookmarks bar: JiraTabs. Then, whenever you are on a filter or search view of Jira’s, click the button and all the jira’s on your screen will open up in new tabs

If you don’t have anything in the right hand column, enable Right-Side Chat from Gmail Labs. We are going to add in some custom css to gmail so install either Stylist for Chrome or Stylish for Firefox.

Add the following style:

div.TZ:nth-child(8) {
    position:absolute !important;
    right:0px;
    top:165px;
    width:164px;
}

In chrome you can also restrict the domain to mail.google.com. For me, the Remember the Milk gadget was the 8th child. Play with this until it looks right for you. You may also have to play with the “top” element depending on how much room your chat gadget takes up

• Want to get some RSS feeds onto the Kindle? (12 feeds for free) KindleFeeder is the way to go. It also has a bookmarklet for capturing and sending whole pages from your browser.

  I use this to send articles in Google Reader that I want to read later to my Kindle. I use my starred items to do this. Starred items have their own RSS feed which you can put into kindlefeeder. For information on how to get the link to the RSS of your starred items, click here.

• “Send to Kindle” for chrome is a button that will send the content of the page your are currently viewing.
• The third method is the built in free Kindle email address that isn’t broadly advertised: your.name@free.kindle.com will beam most docs that you mail it to your Kindle over wifi (does not work with 3G)
• Calibre is great for managing what is on your Kindle and converting just about any file format to .mobi (a format the Kindle can read)

Create a helper like so:

class Timbroder_Stack_Helper_Callstack extends Mage_Core_Helper_Abstract
{
	private function get_callstack($delim="\n") {
	  $dt = debug_backtrace();
	  $cs = '';
	  foreach ($dt as $t) {
	    $cs .= $t['file'] . ' line ' . $t['line'] . ' calls ' . $t['function'] . "()" . $delim;
	  }

	  return $cs;
	}

	public function toLog() {
		Mage::log($this->get_callstack());
	}

	public function toFirePhp() {
		$stack = $this->get_callstack();
		foreach (explode("\n", $stack) as $line) {
			Mage::helper('firephp')->send($line);
		}
	}
}

That can be called from anywhere:

Mage::helper('stack/callstack')->toFirePhp();
Mage::helper('stack/callstack')->toLog();

I’ve also wrapped this into a module that you can drop right into your project. Details here

Thanks to nextide for some of the code

Create the following directory structure: app/code/local/Mage/Widget/Model/Myswql4/Widget/Instance

Copy app/code/core/Mage/Widget/Model/Myswql4/Widget/Instance/Collection.php into your new directory

The Mage_Widget_Model_Mysql4_Widget_Instance_Collection comes with a store filter but thats about it. To be more usefull we are going to add a type filter, a title filter, and a sorter.

class Mage_Widget_Model_Mysql4_Widget_Instance_Collection extends Mage_Core_Model_Mysql4_Collection_Abstract
{
    /**
     * Constructor
     */
    protected function _construct()
    {
        parent::_construct();
        $this->_init('widget/widget_instance');
    }

    /**
     * Filter by store ids
     *
     * @param array|integer $storeIds
     * @param boolean $withDefaultStore if TRUE also filter by store id '0'
     * @return Mage_Widget_Model_Mysql4_Widget_Instance_Collection
     */
    public function addStoreFilter($storeIds = array(), $withDefaultStore = true)
    {
        if (!is_array($storeIds)) {
            $storeIds = array($storeIds);
        }
        if ($withDefaultStore && !in_array(0, $storeIds)) {
            array_unshift($storeIds, 0);
        }
        $select = $this->getSelect();
        foreach ($storeIds as $storeId) {
            $select->orWhere('FIND_IN_SET(?, `store_ids`)', $storeId);
        }
        return $this;
    }

    public function addTypeFilter($type) {
    	$this->getSelect()->where('type=?', $type);
    	return $this;
    }

    public function addTitleFilter($type) {
    	$this->getSelect()->where('title=?', $type);
    	return $this;
    }

    public function addAttributeToSort($attribute, $dir='asc') {
    	$this->getSelect()->order("{$attribute} {$dir}");
    	return $this;
    }
}

Now we should be able to query any widgets from any template in our system:

< ?php
$wids = Mage::getModel('widget/widget_instance')
	->getCollection()
	->addTypeFilter('masswidget/list')
	->addAttributeToSort('title', 'asc')
	->load();

foreach ($wids as $wid):
	$params = $wid->getWidgetParameters();
	echo $params['custom_param'];
	echo $wid->gettitle();
endforeach;
?>

Database
Install innoDB.  Magento can use the in-memory buffer pool to cache table indexes and data.

Configure my.ini:
innodb_buffer_pool_size  = 64M
innodb_thread_concurrency = 4 (or 8 if you have dual core)
query_cache_size = 64M
query_cache_limit  = 2M

apache
enable mod_expires in httpd.conf

php
in php.ini enable:
realpath_cache_size = 16k
realpath_cache_ttl = 120

Install the eAccelerator binaries for php.  APC is a better solution but is less compatible with windows.  If you need to compile these, click here for instructions. Then configure it:
extension=eaccelerator.dll
eaccelerator.shm_size=64
eaccelerator.cache_dir=C:\PHP\tmp
eaccelerator.enable=1
eaccelerator.optimizer=1
eaccelerator.check_mtime=1
eaccelerator.shm_max=0

Install memcached.
add the following lines inside the config of epp/etc/local.xml
<cache>
    <backend>memcached</backend>
    <memcached>
        <servers>
            <server>
                <host><![CDATA[localhost]]></host>
                <port><![CDATA[11211]]></port>
                <persistent><![CDATA[1]]></persistent>
            </server>
        </servers>
        <compression><![CDATA[0]]></compression>
        <cache_dir><![CDATA[]]></cache_dir>
        <hashed_directory_level><![CDATA[]]></hashed_directory_level>
        <hashed_directory_umask><![CDATA[]]></hashed_directory_umask>
        <file_name_prefix><![CDATA[]]></file_name_prefix>
    </memcached>
</cache>
