Moto X4

Back in July (2018), I upgraded to the Motorola Moto X4. After over four-and-a-half years of faithful service, my Moto X (2013) was no longer cutting it. The battery was not lasting a day. I was pretty much out of storage (16GB is not enough), even with a minimal set of apps and music on the device. Topping it off, things were getting generally sluggish.

While I had been looking at phones since December (2017), nothing hit the value mark I was looking for and worked on the Verizon network (they sure do not have “the devices” unless you want a phablet or an iPhone). I was considering the Google Pixel, but given its price point I was disappointed in the second generation device (the screen to body ratio was worse than the Moto X (2013)). I ended up settling for the Moto X4, and picked up the Amazon Prime version on Prime Day.

Breadcrumb NavXT and Bootstrap 4 Breadcrumb

Out of the box Breadcrumb NavXT generates markup that is ready for Schema.org BreadcrumbList compliance. While this is great for most cases, for users of frameworks, some markup changes may be desireable. This article looks at what is necessary to get Breadcrumb NavXT to generate markup compliant with Bootstrap 4’s Breadcrumb component.

The Code

To generate Bootstrap 4 breadcrumb compliant markup, two bits of code are needed. The first is the appropriate calling code (including the proper wrapping markup). Place the following calling code in the appropriate theme file(s) (usually header.php):

<?php if(function_exists('bcn_display_list')):?>
<nav class="breadcrumbs" typeof="BreadcrumbList" vocab="https://schema.org/" aria-label="breadcrumb">
    <ol class="breadcrumb">
        <?php bcn_display_list();?>
    </ol>
</nav>
<?php endif; ?>

The second bit of code goes into a site specific plugin:

add_filter('bcn_display_attributes', my_display_attributes_filter, 10, 3);
function my_display_attributes_filter($attribs, $types, $id)
{
    $extra_attribs = array('class' => array('breadcrumb-item'));
    //For the current item we need to add a little more info
    if(is_array($types) &amp;&amp; in_array('current-item', $types))
    {
        $extra_attribs['class'][] = 'active';
        $extra_attribs['aria-current'] = array('page');
    }
    $atribs_array = array();
    preg_match_all('/([a-zA-Z]+)=["\']([a-zA-Z0-9\-\_ ]*)["\']/i', $attribs, $matches);
    if(isset($matches[1]))
    {
        foreach ($matches[1] as $key => $tag)
        {
            if(isset($matches[2][$key]))
            {
                $atribs_array[$tag] = explode(' ', $matches[2][$key]);
            }
        }
    }
    $merged_attribs = array_merge_recursive($atribs_array , $extra_attribs);
    $output = '';
    foreach($merged_attribs as $tag => $vals)
    {
        $output .= sprintf(' %1$s="%2$s"', $tag, implode(' ', $vals));
    }
    return $output;
}

This code adds the breadcrumb-item to every breadcrumb in the trail. Additionally it adds the active class and the arria-current attribute to the current item. While the first could be easily achieved by updating every Breadcrumb template, this solution is easier to implement and allows us to use bcn_display_list().

Unfortunately, the bcn_display_attributes filter available since Breadcrumb NavXT 6.0 is not the easiest use in an efficient and robust manner. In the future a new filter will be added to address this deficiency. As presented, my_display_attributes_filter will be greatly simplified with said new filter (lines 11-22 and 24-28 go away). This article will be updated at that time to reflect the changes in API.

Fix Bluetooth Mouse Pairing but not Moving Cursor in Linux

I recently picked up a Logitech M585 to replace my old M577 which was randomly registering multiple clicks for each left click. This was the second button to go bad on that mouse so it was time for an upgrade (the back click action on the mouse wheel had gone out a year back).

While I had no problems pairing the M585 with my laptop running Linux, it was not moving the cursor and mouse clicks were not registering. This is not the first mouse that I’ve had issues with on this laptop, the Microsoft Bluetooth Mobile Mouse 3600 exhibited a similar behavior. Checking the system logs, I found the following clue:

[bluetoothd] input-hog profile accept failed for XX:XX:XX:XX:XX:XX

Where XX:XX:XX:XX:XX:XX is the bluetooth address for the mouse. After some digging, I came across the solution. CONFIG_UHID needs to be set to ‘y’ in the kernel config to enable userspace I/O driver support for the HID subsystem.

CONFIG_UHID=y

After making this change, recompiling the kernel and rebooting the M585 pairs and works properly as a mouse. Additionally, the MS Bluetooth Mobile Mouse 3600 now works properly as well.
