Original iPod Shuffle – on Linux

That’s right, I’ve finally found a way to use my old 512mb Shuffle on Linux. Thanks to keyj for making a simple python script in 2006. How it works is you put whatever you want for mp3s onto the shuffle (after mounting it in linux) then move the python script onto the root of the ipod. Then run the script in terminal after navigating to the root of the mounted iPod:

$ python rebuild_db.py

Here is a link to the python file on sourceforge.

Thank you internet!

Current thoughts

“No man ever wetted clay and then left it, as if there would be bricks by chance and fortune.”

– Plutarch

It is sometimes hard to remember that we cannot just simply start a process and then leave it be and assume it will finish of its own volition. Whether referring to child rearing, gardening, politics, or any other number of things – once you start something, you must finish it.

Rest in peace, Ashes

Yesterday we had to lay our son, Ashes, down to rest. He was 14 years old and had been with us since we were a young couple in college. I loved that cat more than I realized. He helped me through many of my struggles with panic and anxiety over the years. We miss you, Ashes.

RSS displayed with PHP – Updated!

A week ago I posted about using PHP to display an RSS feed. We moved to a new server that did not have DOM enabled, so I have updated my code to use curl instead of DOMDocument.  Either method does work, but this is nice and clean.  See below for my new code:


<html>
<head>
<link rel="stylesheet" href="/alert-rss.css" media="all">
</head>

<body>

<?php

//set timezone
date_default_timezone_set('America/New_York');

//set RSS feed
$handle = curl_init('https://url-of-rss-feed.com');

curl_setopt($handle, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($handle, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($handle, CURLOPT_FOLLOWLOCATION, TRUE); 
curl_setopt($handle, CURLOPT_CUSTOMREQUEST, "GET");
curl_setopt($handle, CURLOPT_ENCODING, 'identity');

//get RSS feed from $handle
$response = curl_exec($handle);

curl_close($handle);

$xml = simplexml_load_string($response, "SimpleXMLElement", LIBXML_NOCDATA);
$json = json_encode($xml);
$data = json_decode($json, true);

//load feed
$feeds =  array();

//load only required feed items
if(isset($data['channel']['item'])) {
    foreach($data['channel']['item'] as $item) {
        $feeds[] =  array(
            'title' =>  $item['title'],
            'desc'  =>  $item['description'],
            'date'  =>  $item['pubDate'],
        );
    }
}

//set the internal point of the array to last element
end($feeds);

//pull key of array at pointer so we only display one entry
$key = key($feeds);

//set variables to display data from array
$title = $feeds[$key]['title'];
$description = $feeds[$key]['desc'];
$date = date('l F d, Y g:ia', strtotime($feeds[$key]['date']));

//set $end_date for when RSS expires - calculation entered as (hours*secondsperhour)
$end_date = date('l F d, Y H:i', strtotime($feeds[$key]['date']) + (18*3600));

//set how date variables are calculated for comparison purposes
$today = date('l F d, Y H:i');
$today_calc = strtotime($today);
$end_date_calc = strtotime($end_date);

//display what we have found if it is current
if($today_calc < $end_date_calc) {
	echo '<div id="blinky-div"><p><strong>'.$title.'</strong><br />';
	echo '<small><em>Posted on '.$date.'</em></small></p>';
	echo '<p>'.$description.'</p></div>';
//hide div if there is no current data
} else {
	    echo '<div style="display: none;">No current RSS</div>';
}
?>

</body>

Display RSS feed as alert using PHP

Our school district had a need where we wanted to have the no school notice show on all of our district pages when an alert is sent out.  I wanted to automate the process so that there wouldn’t need to be any intervention last minute.  The alert system we use, Alert Solutions, has an option to output to an RSS feed.  By using this and a small amount of PHP, I was able to get the alerts to show up on the site automatically and display for 18 hours without any special intervention other than when the admin makes the notification, they have to remember to check the “RSS” box as well. 

The issue became that the RSS feed never lets go of any posts, and on top of that, it outputs the oldest at the top.  To fix this, we look for the number of keys, then pull only the latest key.  This means that we are only looking at the most recent entry.  If it is less than 18 hours old, it is displayed automatically.  Otherwise the div is set to display:none; and doesn’t show.

Below is the code I used.


<html>
<head>
<link rel="stylesheet" href="/alert-rss.css" media="all">
</head>

<body>

<?php
	//Set timezone and load array with only the fields we need
	date_default_timezone_set('America/New_York');
	$rss = new DOMDocument();
	$rss->load('https://url-of-rss-feed.com');
	$feed = array();
	foreach ($rss->getElementsByTagName('item') as $node) {
		$item = array ( 
			'title' => $node->getElementsByTagName('title')->item(0)->nodeValue,
			'desc' => $node->getElementsByTagName('description')->item(0)->nodeValue,
			'date' => $node->getElementsByTagName('pubDate')->item(0)->nodeValue,
			);
		array_push($feed, $item);
	}
	
	
	//Find the last entry array key so we only display current RSS feed
	end($feed);
	$key = key($feed);
	
	//Set variables to pull appropriate data from array
	$title = str_replace(' & ', ' &amp; ', $feed[$key]['title']);
	$description = $feed[$key]['desc'];
	$date = date('l F d, Y H:ma', strtotime($feed[$key]['date']));

	//Set $end_date for when RSS expires.  Calculation entered as (hours*secondsperhour).
	$end_date = date('l F d, Y H:ma', strtotime($feed[$key]['date']) + (18*3600));

	//Set how today is calculated for comparison purposes
	$today = date('l F d, Y H:ma');

	//Display what we have found if it is current
	if($today < $end_date) {
		echo '<div id="blinky-div"><p><strong>'.$title.'</strong><br />';
		echo '<small><em>Posted on '.$date.'</em></small></p>';
		echo '<p>'.$description.'</p></div>';
	//Hide DIV if there is no current data
	} else {
		    echo '<div style="display: none;">No current RSS</div>';
	}

?>

</body>
</html>

 

And here is the CSS I used:

@keyframes blink { 
    50% {
   	border-color: #ff0000; 
   	border-style: solid;
   	border-width: 4px;
   	}
   	0% {
   	border-color: #fff; 
   	border-style: solid;
   	border-width: 4px;
   	} 
}
#blinky-div {
    animation-name: blink ;
    animation-duration: .5s ;
    animation-timing-function: step-end ;
    animation-iteration-count: infinite ;
    animation-direction: alternate ;
}
