If this works there should be about 6 thumbnails on this page, showing links bookmarked using Delicious, and tagged with “art”.


Download:
Download delicious_screenshots.zip here, version 0.7 of my very first wordpress plugin.

Usage:
Activate plugin. And add your del.icio.us username to the options page. (under settings in the WordPress toolbar)
https://i2.wp.com/pappmaskin.no/wp-content/2011/07/20081020-jq6mtqhq3k4pu475bffhjuppcs.jpg?w=525

Changelog:
14.02.2017: Changed from rss to json and cleaned the code up a bit. Also removed Snapcasa from options.

What’s next:

  1. The first version of this plugin used Snapcasa for creating thumbnails, but I switched to thumbalizr.com to get a higher success rate.
  2. The count param doesn’t seem to do anything when calling the del.icio.us api, it always returns 10 results, so I need to handle that in the code instead. I’ve notified them of the bug.
  3. Testing other screenshotting services or making my own.
  4. Choosing an image from the page metadata when available.

Playing with SnapCasa screenshots and del.icio.us

Tonights nerdfest will include trying to use the SnapCasa and del.icio.us to generate a lovely page full of thumbnails, one for each url.

Ingredients:

1. My 100 latest bookmarked urls from del.icio.us: http://feeds.delicious.com/v2/rss/mskogly?count=100
2. A SnapCasa login account.
3. A server that supports xslt transformation. (I’m running MAMP on my macbook, and pappmaskin is hosted on One.com)
4. A text editor. I’m using Dreamweaver for this, since it has some pretty good tools for building xslt. (Take a look at the Adobe Livedocs for more info on using it).

Code: Showing a list of youtube videos using gdata and xslt with php


Let’s start with a little demonstration. The section below is made by calling the php-script https://pappmaskin.no/opensource/youtube/youtube.php?s=super&max=9 within an iframe:

Why iframe?
Just to make it easier to reuse and embed Youtube videos on different sites, and because it makes it easier to try out new ideas without adding messy bits to a larger project. Sort of like rapid prototyping/proof of concept before “committing” to a feature and spending alot of time integrating something you might end up throwing out.

This solution currently consists of these files:
youtube.php, takes s=whateveryouwanttofind and max=number of videos to return as GET parameters
youtube5.xsl, does all the transformation of the xml from youtube into lovely xhtml.
youtube.js, javascript file that handles clicking on the thumbnails to load a new video, using innerHtml
youtube.css, minimalist styling to keep things pretty.
swfobject.js, for embedding flash

The xslt:

<?xml version=”1.0″ encoding=”UTF-8″?> <xsl:stylesheet version=”1.0″ xmlns:xsl=”http://www.w3.org/1999/XSL/Transform” xmlns:fn=”http://www.w3.org/2005/xpath-functions” xmlns:gd=”http://schemas.google.com/g/2005″ xmlns:media=”http://search.yahoo.com/mrss/” xmlns:n1=”http://www.w3.org/2005/Atom” xmlns:openSearch=”http://a9.com/-/spec/opensearchrss/1.0/” xmlns:xdt=”http://www.w3.org/2005/xpath-datatypes” xmlns:xs=”http://www.w3.org/2001/XMLSchema” xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance” xmlns:yt=”http://gdata.youtube.com/schemas/2007″ xmlns:altova=”http://www.altova.com”> <xsl:output method=”html” encoding=”ISO-8859-1″ doctype-public=”-//W3C//DTD XHTML 1.0 Transitional//EN” doctype-system=”http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”/> <xsl:param name=”SV_OutputFormat” select=”‘HTML'”/> <xsl:variable name=”XML” select=”/”/> <xsl:template match=”/”> <html> <head> <title>Pappmaskin.no – Youtube playlist</title> <link rel=”stylesheet” href=”youtube.css” media=”screen” /> <script type=”text/javascript” src=”youtube.js”></script> <script type=”text/javascript” src=”swfobject.js”></script> </head> <body> <div id=”youtube”> <h1>YouTube Playlist</h1> <xsl:for-each select=”$XML”> <xsl:for-each select=”n1:feed”> <xsl:if test=”n1:entry[1]”> <div class=”youtubevideo”><div id=”cur_video”> <xsl:for-each select=”n1:entry[1]/media:group/media:content”> <xsl:if test=”@type = ‘application/x-shockwave-flash'”> <embed> <xsl:attribute name=”src”> <xsl:value-of select=”@url”/> </xsl:attribute> <xsl:attribute name=”width”>480</xsl:attribute> <xsl:attribute name=”height”>385</xsl:attribute> <xsl:attribute name=”quality”>high</xsl:attribute> <xsl:attribute name=”bgcolor”>#000</xsl:attribute> <xsl:attribute name=”id”>cur_video_swf</xsl:attribute> <xsl:attribute name=”name”>cur_video_swf</xsl:attribute> </embed> </xsl:if> </xsl:for-each> </div> <!– ends cur_video –> <div id=”cur_video_title”> <xsl:value-of select=”n1:entry[1]/n1:title”/> </div> </div>    <!– ends youtubevideo –> </xsl:if> <div class=”youtubethumbs”> <xsl:for-each select=”n1:entry”> <xsl:if test=”position() > 1″> <xsl:for-each select=”media:group”> <div class=”youtubethumb”> <xsl:for-each select=”media:content”> <xsl:if test=”@type = ‘application/x-shockwave-flash'”> <a> <xsl:attribute name=”href”>#</xsl:attribute> <xsl:attribute name=”onmousedown”>PlayVideo(‘<xsl:value-of select=”@url”/>’,’http://img.youtube.com/vi/h8oBykb_Pqs/2.jpg’, ‘Youtube’, true);</xsl:attribute> <xsl:attribute name=”onclick”>return false;</xsl:attribute> <xsl:for-each select=”../media:thumbnail[1]”> <xsl:element name=”img”> <xsl:attribute name=”src”><xsl:value-of select=”@url”/></xsl:attribute><xsl:attribute name=”lowsrc”>lowsrc.gif</xsl:attribute><xsl:attribute name=”width”>100</xsl:attribute><xsl:attribute name=”height”>60</xsl:attribute> </xsl:element> </xsl:for-each> <xsl:value-of select=”../media:title”/> </a> </xsl:if> </xsl:for-each> </div> <!– ends avslutter class youtubethumb –> </xsl:for-each> </xsl:if> <!– end if on position > 0 –> </xsl:for-each> </div><!– ends class youtubethumbnails –> </xsl:for-each> </xsl:for-each> <div class=”youtubefooter” style=”clear: both; color: #999999; font-size: 0.8em;”>Disclaimer: These videos are retrieved from Youtube through a simple search.

How to present a music festival-guide?

My colleagues over at Lydverket published a great festival guide today, and I have been thinking of ways to enhance it.

We recently made a page that fetches artsts info from several websites, like imeem, youtube, last.fm, flickr and wikipedia, for use together with NRKs radio playlists, and I wanted to miks Lydverkets guide with this aristinfo service.

The easiest way would be to simply link each artist in their festival guide to the corresponding arist page, but the first problem is that the layouts are quite different. To solve this we changed the artist info page to take a folder id as a paramter, so that we can change its layout dynamically. And is so happens that we have a folder that has no layout at all, which means I can do something like this:
http://www2.nrk.no/spillelister/LaatInfo.aspx?artist=Santogold&ppfolder=p3

This gave me the sudden urge to just insert an iframe dynamically under each artist name in the festival guide, so that you can simply click on an artist, and get a ton of information, music, videos, etc, but the problem with this is that there is simply TOO MUCH information.

Luckily, the artist info page is build up of several smaller, freestanding pages, placed in the artist info page using iframes (mostly). This means that I can break it all up, and perhaps create a tabbed interface for each artist in the festival guide, which I will work some more on tomorrow.

But until then I want to test a few other things:

A few minutes ago I went through the list of the 17 bands that are scheduled to play at the Hove festival (www.hovefestivalen.no), seached them all up on youtube, and placed them in a standard youtube playlist. I then created a custom player, that looks like this:

Hove – Day 1:

Hove – Day 2

Perhaps it could be as easy as this? I you are reading a festival guide, what else do you need than a fast way to check out each artist? Is one youtube video is for me enough to tell me wether or not to see a band live? Perhaps.

I think I will insert this little youtube player in the page and ask around tomorrow if it works or not, and then I will do some tests with the youtube api to see if a can extract my playlist as xml and present is as I wish.

Code: Gameinfo + Gametrailers + Youtube Mashup

Norsk? Du finner en norsk versjon av denne artikkelen på NrkBeta.no

I recently made a Gameinfo service for spiller.no. It pulls in licenced gameinfo from our partner GameXplore though XML, and combines it with a search for related videoes from Youtube before it is presented on the page.

Example: FIFA STREET 3 Gameinfo – NRK Spiller

Youtube + Google Api
I made the Youtube part as a standalone page, and I include it with iframe. The reason I used Iframe was to make it easily reusable on other projects where it would fit to do something similar. I can for instance include it in my blog like this:

The page takes any search term as a GET, in this example it simply queries the youtube google api with the title of the game, with a few extra parameters (limit on the number of returned movies + a filter to remove “adult content”). I spent some time to create the XSLT to convert the xml from youtube/google to html, which is basically the same format for many of Googles services. I spent hours trying to find out if someone had created this already, but since I couldn’t find anything I had to create it myself. If you want to learn more about the youtube api I suggest starting at the Youtube Api group on Google Groups.

Open source

I have gotten some emails asking for the xslt for the youtube search, so I wanted to share it here:

This is my input, an example Youtube search

This is my example output:
https://pappmaskin.no/opensource/youtube/youtube.php

And here is the xslt I used to produce the above result:
https://pappmaskin.no/opensource/youtube/youtube3.xsl

If you have any questions, feel free to ask in the comments.

Spam? Porn? Nope!
I was of course a little worried about what the youtube search would return, so when testing I went through quite a few games to see if the search returned movies that were unrelated to the gametitle, or contained nudity, but so far it looks really good, the youtube videos are actually the most interesting part of the service, so I’m really happy with it!

Blip.tv gametrailers
Yesterday I also added gametrailers to the mix, check out the gamepage for Assassins Creed for an example (click on the huge image at the top of the page) to make it play. I have bought a lisence for the wonderful Jeroen FLV Media Player which I use to present the gametrailers.

New gametrailers page, based on blip.tv
After that I spent a few minutes to create a new page that lists all the latest gametrailers published through GameXplore. I use the Jeroen Flv Media Player for this page as well. I created this yesterday, so I have to debug it a little bit before we start to promote it, and I also have to consider to increase the video buffer time, it seems like blip.tv har pretty slow servers. Right now there is a five second buffer, which should be more than enough, but even with broadband connection the video stops and buffers every five second. I don’t want people to wait forever for the video to buffer, but it is super irritating when the video stops every 5 seconds to buffer, so I have to decide what to do with it. One (hard) solution could be to download all the .flv to my server and play them from there… I am a big fan of blip.tv, they have the best player around, and their cross posting abilities are great (at least in theory, I still haven’t gotten it to work with this blog or myspace), so I am a little dissapointed to discover that the blip.tv servers (or lines?) are so slow to deliver video. (to Norway at least).

Thickbox
I love the Jquery javascript library, and I love Thickbox, so I decided to use it on the Screenshots on the site, popping them up in their own little box. I modidied the thickbox script and css slightly, replacing the animated loading gif and moved things around a little bit, and I am really happy about the outcome.

Userscripts.org: Amazon Sambok and BIBSYS ISBN Search

Hey, my first Greasemonkey userscript!

Userscripts.org: Amazon Sambok ISBN Search:

This is just a fast remake of the Hight Library Linky script. Its my first script, just wanted to check out how hard it would be to rework. Luckily for me it was super easy. It inserts links to two norwegian bibliographical databases.

Bibsys, containing material from universities and colleges.
And Sambok, containing material from most Public Libraries in Norway.

Pretty useful, at least in theory, since ISBN search is quite limiting. But it will have to do for now.
