In Fedora I prefer to apply updates just before shutting down so that next time I boot up the updates will be in place. For me this seems like the best way to do it. To make that easier I also then create a keybinding so that I can hit [Start]+[q] to trigger the upgrade/shutdown process in a terminal Being a lazy developer I prefer to have things automated and

What is atop? Taken from the man page: The program atop is an interactive monitor to view the load on a Linux system. It shows the occupation of the most critical hardware resources (from a performance point of view) on system level, i.e. cpu, memory, disk and network. Raw Data Format The raw data format is a binary log file that atop can be configured to record. This log file can be generated for any length of time and allows you to go back in time to debug system performance issues.

The tabs on the product page are handled by the Magento_Catalog’s product/view/details.phtml template file. In there the line $block->getGroupChildNames('detailed_info', 'getChildHtml') collects all blocks in the detailed_info group for the tabs. This means the following layout XML will add a new tab: <referenceBlock name="product.info.details"> <block class="Magento\Framework\View\Element\Template" template="Magento_Theme::path/to/template.phtml" name="INSERT NAME" group="detailed_info"> <arguments> <argument name="title" translate="true" xsi:type="string">TAB TITLE HERE</argument> </arguments> </block> </block> </referenceBlock> The group="detailed_info" part adds it to the tabbed area. The <argument name="title" part of that sets a string value on the block which will be used for the tab’s title.

TL;DR Run the script at the bottom. The Issue If you’ve previously applied the SUPEE-1533 patch to your Magento site, then when you try to apply the SUPEE-8788 patch you’ll see the following error: checking file app/code/core/Mage/Adminhtml/controllers/DashboardController.php Hunk #1 FAILED at 91. 1 out of 1 hunk FAILED This is caused by the fact that the SUPEE-8788 patch seems to have been taken against an un-patched version of Magento. This can be seen from the following: The SUPEE-8788 patch contains: @@ -91,7 +91,7 @@ class Mage_Adminhtml_DashboardController extends Mage_Adminhtml_Controller_Actio if ($gaData && $gaHash) { $newHash = Mage::helper('adminhtml/dashboard_data')->getChartDataHash($gaData); - if ($newHash == $gaHash) { + if (hash_equals($newHash, $gaHash)) { if ($params = unserialize(base64_decode(urldecode($gaData)))) { $response = $httpClient->setUri(Mage_Adminhtml_Block_Dashboard_Graph::API_URL) ->setParameterGet($params) The important line here is: if ($params = unserialize(base64_decode(urldecode($gaData)))) { Which is supposed to match up with: if ($gaData && $gaHash) { $newHash = Mage::helper('adminhtml/dashboard_data')->getChartDataHash($gaData); if ($newHash == $gaHash) { $params = json_decode(base64_decode(urldecode($gaData)), true); if ($params) { $response = $httpClient->setUri(Mage_Adminhtml_Block_Dashboard_Graph::API_URL) ->setParameterGet($params) The important lines here are: $params = json_decode(base64_decode(urldecode($gaData)), true); if ($params) { Now they don’t match because of the change made in SUPEE-1533: if ($gaData && $gaHash) { $newHash = Mage::helper('adminhtml/dashboard_data')->getChartDataHash($gaData); if ($newHash == $gaHash) { - if ($params = unserialize(base64_decode(urldecode($gaData)))) { + $params = json_decode(base64_decode(urldecode($gaData)), true); + if ($params) { $response = $httpClient->setUri(Mage_Adminhtml_Block_Dashboard_Graph::API_URL) ->setParameterGet($params) The Fix In order to apply SUPEE-8788 we need to temporarily revert the changes made to DashboardController.php by SUPEE-1533.

While developing a site, you often put a pile of placeholder links in with a plain <a href="">Link</a>. These can sometimes sneak through because they’re so easily forgotten about. A simple CSS block will automatically highlight these for you, so you don’t forget: a[href='']:after { content:'!'; background:red; color:#FFFFFF; padding-left:3px; padding-right:3px; opacity:0.3; white-space: nowrap; } a[href='']:hover:after { content:'empty link'; opacity:1.0; } You can adjust the selector if you use href="#" instead of blank ones.
