The RiverLevels widget provides an easy way to monitor the amount of water flowing in your favorite streams and rivers right from your Dashboard. The RiverLevels widget is of particular interest to whitewater kayakers and canoeists.

Once any United States Geological Survey (USGS) stream-gauge station is selected, it is automatically refreshed to always provide you with the latest graph of the water-level. As of version 1.2 you can choose between two graph styles: discharge in cubic feet per second (CFS) and water-height in feet.

For the past 6 months our Web Application Development work-group has been Bugzilla as our issue tracker with quite a bit of success. While it has its warts, Bugzilla seems like a pretty decent issue-tracking system and is flexible enough to fit into a variety of different work-flows. One very important feature of Bugzilla is support for LDAP authentication. This enables any Middlebury College user to log in and report a bug using their standard campus credentials.

While LDAP authentication works great, there is one problem: If a person has never logged into our Bugzilla, we can’t add them to the CC list of an issue. This is important for us because issues usually don’t get submitted directly to the bug tracker, but rather come in via calls, emails, tweets, and face-to-face meetings. We are then left to submit issues to Bugzilla ourselves to keep track of our to-do items. Ideally we’d add the original reporter to the bug’s CC list so that they will automatically be notified as we make progress on the issue, but their Bugzilla account must exist before we can add them to the bug.

Searching about the internet I wasn’t able to find anything about how to import LDAP users (or any kind of users) into Bugzilla, though I was able to find some basic instructions on how to create a single user via Bugzilla’s Perl API. To improve on the lack of user-import support I’ve created an Perl script that creates users from lines in a tab-delimited text file (create_users.pl) as well as a companion PHP script that will export an appropriately-formatted list of users from an Active Directory (LDAP) server (export_users.php).

I have been using Twitter as a log of my daily doings and wished to export my time-line for reformatting into a calender format. Unfortunately TweetDumpr just retrieves the list of Tweets using a single fetch request which is limited by the Twitter API to a maximum of 200 Tweets. (Update: apparently TweetDumpr can get more than 200 Tweets. It just didn’t say so in its description.)

I wanted to export all 600+ of my tweets, so I wrote the following little php script to accomplish this. I have not yet tested it with many concurrent users or added a form to select which user to update. Until I do so, I won’t be providing it as an end-user service. You are free to put it on your own machine and use it though.

TwitterExport.php

<?php
/**
 * This script will allow the export of complete user time-lines from the twitter
 * service. It joins together all pages of status updates into one large XML block
 * that can then be reformatted/processed with other tools.
 *
 * @since 10/13/08
 *

 */

$user = 'afranco_work';	// Replace this with your user name.

header('Content-type: text/plain');

$allDoc = new DOMDocument;
$root = $allDoc->appendChild($allDoc->createElement('statuses'));
$root->setAttribute('type', 'array');

$page = 1;
do {
	$numStatus = 0;

	$pageDoc = new DOMDocument;
	$res = @$pageDoc->load('http://twitter.com/statuses/user_timeline/'.$user.'.xml?page='.$page);
	if (!$res) {
		print "\n\n**** Error loading page $page ****";
		exit;
	}
	foreach ($pageDoc->getElementsByTagName('status') as $status) {
		$root->appendChild($allDoc->createTextNode("\n"));
		$root->appendChild($allDoc->importNode($status, true));
		$numStatus++;
	}

	print "\nLoaded page $page with $numStatus status updates.";
	flush();

	$page ++;
	sleep(1);

} while ($numStatus);

print "\nDone loading timeline.";
print "\n\n\n";

$root->appendChild($allDoc->createTextNode("\n"));
print $allDoc->saveXml();

Usage (assuming PHP is installed)

1. Save the code above on your machine as twitter_export.php
2. Edit the code to change the $user variable to be your own Twitter username
3. From the command line run php twitter_export.php
4. Copy/paste the XML output into a file for safe keeping and further processing

I’ve recently developed a small PHP script, the WPEnclosureAdder (source | try) that goes through each item in an RSS feed, looks for links to YouTube videos or GoogleVideo videos, and then adds an enclosure tags for the videos. If multiple videos are found embedded in a post, then that post is duplicated in the feed for each additional URL to provide compatibility with the many RSS readers/video-podcast viewers that expect a single enclosure per post.

I wrote this script because I have been recently making heavy use of Miro (formerly known as “The Democracy Player“) to download videos from YouTube in order to watch them off-line. Miro also provides a nice UI for aggregating videos and remembers my spot when I go back to watching later (nice for long documentaries). Miro however, expects links to videos in RSS enclosure tags, something that WordPress (and probably other blogging software) doesn’t do for embeded videos.

Throw Away Your Telescreen is a video blog done by one of my favorite geo-political bloggers, Dave on Fire, and a few others. In it they link out to the most interesting “documentaries, lectures, and interviews that follow a different editorial line” from the corporate press. I highly recommend all of the videos on it that I have seen.

Throw Away Your Telescreen has all the makings of an indie-news channel, perfect for Miro which was developed to encourage participatory media and culture. The only thing missing was to get the videos embedded in Throw Away Your Telescreen’s posts in such a way that Miro can find them. With the WPEnclosureAdder, this has now been done. Use this feed to view Throw Away Your Telescreen in Miro.

• View the source-code of the latest version. (save-as to download)
• License: GNU General Public License (GPL) version 3 or later
• Requirements (for hosting it yourself): PHP version 5.2 or later
• Git Repository: http://www2.adamfranco.com/WPEnclosureAdder.git

I wrote this script with Throw Away Your Telescreen in mind, but it should work with any other WordPress blog, and probably with RSS feeds generated from other blogging tools. To point it at another blog’s RSS feed, enter the feed url in the form below:

Using my version will use my default search strings for YouTube and GoogleVideo videos. If you would like to change what is being searched for, please download the script, change the configuration, and host it on your own website. I have licensed the WPEnclosureAdder under the GNU General Public License (GPL) version 3 or later, so you are free to copy and modify this script as per the terms of that license.

Tags: development, GIS/GPS, KML, PHP

As of a few days ago, I am now able to generate KML versions of Flickr photosets for viewing in Google Earth/Maps. With that taken care of, I also want to easily combine these KML documents of images together with other KML files that show additional information, such as paths traveled, points of interest, etc.

To accomplish this task, I have written a new script, the KML Joiner that will combine any KML documents on the web together into a single (referenced) KML document. (try it out)

More Detail: for those interested in KML
The resulting document is a collection of network links, each of which points to one of the KML URLs specified. Doing this rather than combining their text together into a static KML document prevents style collisions as well as allows changes in the source data to propagate to the combined document.

Refresh intervals can optionally be specified for every source document allowing for a server-friendly combination of static data with rapidly changing data. By default, no refresh interval is specified, making the linked documents load only once when first accessed.

Example:

View the KML Joiner with fields filled in that generates the map below.

View Larger Map

The map above is of the trip mentioned in a previous blog post, but this time the data sources (1. a static KML file with the path and house placemark, 2. a dynamic KML document generated with my Photo set to KML script) joined together with the KML Joiner script instead of manually put together with a text editor.

Usage:
You are welcome to use this script hosted on my site, or you can download it and run it on your own computer/webserver.

This script is available under the GNU General Public License (GPL) version 3 or later. (Source Code)

Please post any suggestions for fixes or changes. Thanks!

One of the things I (and others) have found lacking when working with geotagged images on Flickr, is the inability to retrieve a “photo set” (Flickr’s take on a slideshow) as a KML document that can then be displayed in GoogleEarth, GoogleMaps, or other geo-browsers. Flickr provides some KML links and GeoRSS feeds, but these are either limited to 20 items or can only be pointed at tags or users’ photo-streams, not a particular photo set.

To fill this niche, I present a small script I wrote to generate a KML file from the geotagged photos in a set:

Features:

• Generate a KML file from a Flickr photo set
• Directly open the KML file in Google Maps
• Choose what size image to include in the placemark description for each photo.
• Optionaly draw a path (line) from photo to photo ordered in one of several ways: by date taken, by date uploaded, by set order. Useful for making a quick and dirty map of a trip.

Examples:

• KML / GoogleMaps – Some photos from Cape Cod.
  
  View Larger Map
   
• KML / GoogleMaps – A set of photos from a trip I took around Turkey, with lines drawn chronologically. Since this is a large set that causes GoogleMaps to time-out, I’ve downloaded the KML file and then re-uploaded it to my website. This is the method I recommend for large photo sets.
  
  View Larger Map
   

You are welcome to use this script hosted on my site, or you can download it and run it on your own computer/webserver. If you would like to run it yourself, please be aware of the following…

System Requirements:

• PHP 5.2 or greater.
• The PEAR Flickr API

This script is available under the GNU General Public License (GPL) version 3 or later. (Source Code)

Updates::

• 2011-10-06
  • Moved the source-code to Github
• 2007-08-27
  • Now uses htmlspecialchars() to clean titles instead of htmlentities(), the latter of which was causing excessive translation of German characters. Thanks Stefan Geens, for pointing this out.
  • Form now generates valid XHTML 1.0 strict.
  • Now can use image thumbnails instead of camera icons. Thanks for the idea Nicolas Hoizey.
• 2007-08-24
  • Now escapes ampersands in titles and descriptions. Thanks Jesse for pointing this out.

  Future Improvement Ideas::

  • Add an option for icon size.
  • Add options for custom icon/path styles. I’m not sure whether to give several options, or just provide a field for a block of arbitrary KML style-markup.

Quite a few of my friends and relatives make use of Blogger/Blogspot for their weblogs. While Blogger seems to be a great service and very easy to use, what annoys me is that RSS feeds are often disabled on Blogger weblogs. Maybe people are setting this on purpose, maybe they are turning off RSS feeds unintentionally, or maybe that is the default. Either way, I read all of my news and blogs in an RSS reader. Friends & family blogs and photo-streams make up about 25 of the 100+ feeds I subscribe to. If a blog doesn’t have an RSS feed for me to subscribe to, I’m never going to remember to read it.

So, my work-around for Blogger was to write a screen-scraping RSS generator that creates an RSS feed from a Blogger weblog. BlogspotRSS is a simple PHP5 script that makes use of XPATH queries to turn the Blogger weblog into an RSS document. If you have a web server with PHP5, please download BlogspotRSS and run it on your own web server to save my bandwidth.

The BlogspotRSS script is licensed under the GNU General Public License (GPL).

Notes:

• It seems that some of the Blogger themes change the HTML quite a bit. I’ll have to fix up the RSS generator to make it work with a few more themes than the ones I tested it on…
