  Adding Flickr photos to Foursquare using YQL 

  

  Image by miss604 via Flickr

  Browsing the updated Foursquare development documents I came across a real nice hidden gem: it appears that the Flickr folks have enabled so called machine tags to associate a photo with a Foursquare venue.

  The almost hidden quote from the Flickr Developer blog:

  This is the part where I casually mention that we’ve also added machine tags extra love for Four Square venues IDs. I’m just saying…

  Now how cool would it be to display a little photo on my Foursquare Layar venue detail pages?
  Remembering @codepo8‘s execellent talk at the Fronteers conference last week, I realized that this is where the really cool YQL engine comes in really handy.

  And indeed, the following query does it all:

  select * from flickr.photos.search
      where machine_tags="foursquare:venue=132009"
      limit 1

  Just save the REST command url, wrap it in a little PHP handler and we’re good to go (homework for next time: process the YQL response in XML format with js/e4x and skip the PHP part altogether).

  So now you will see a little thumbnail picture for every venue which has a photo tagged on Flickr. There aren’t many yet, but hey, it’s a start!

  See it in action in the Foursquare Layar app on your phone (iPhone, Android) or read my announcement for more background information about the foursquare layar app.

  Choice of PHP Frameworks 

  

  Image via Wikipedia

  As of today there is a Tweet Poll running with the question: Which PHP opensource framework do you mostly use?
  An interesting question because the market of PHP frameworks appears pretty fragmented after 750+ votes are cast. Leading is Zend Framework (does this qualify as Open Source?), followed by Symfony, Cake PHP, CodeIgniter, all around 10%. There are also a few stray ones: I don’t consider PEAR a framework and the choice “my own” can be disputed as well.

  For now there is no clear winner, something I already had that gut feeling about. Wonder where this is going to stabilize (and of course, how representative the twitter votes are anyway). See for yourself, the embedded graph below should stay up to date and you may cast your vote if you ike.

  Semantic Web Technology for SEO 

  

  Image by Getty Images via Daylife

  Since the early days of Sematic Web I have been expecting that this technology would become very important for Search Engine Optimization.

  Until recently, however, the most important component for this to happen has been missing: the major search engines completely ignored RDF and other semantically enriched markup.

  This as changed now finally Yahoo and, more recently, Google announced to analyze and index rich mark up like microformats and RDFa.

  Just today I stumbled upon a nice article by the E-business and Web Science Research Group of the Universität der Bundeswehr München titled GoodRelations and Yahoo SearchMonkey with five very practical examples how to enhance your web pages for better relevance in the Yahoo search index.
  They make use of RDFa and the GoodRelations Web Ontology.

  This is all very exciting and I expect way more to come!

  Firefox 3.5 does geolocation! 

  

  Image by KonMan via Flickr

  Since early beta release of Firefox 3.1 there is experimental support for the experimental W3C Geolocation API.

  Now Doug Turner, one of the engineers who is behind the Geolocation support in Firefox, wrote a nice background story geolocation in Firefox 3.5 (hacks.mozilla.org). A very interesting read, and it turns out that geolocation is not only for mobile devices, but also available in regular Firefox versions, using wifi or IP address mapping.

  Using Firefox 3.5 or another location aware browser? Give it a try by clicking the button below, a map with your current location will be loaded…

  Note:

  • Firefox 3.5b4 has an annoying bug (#490046) which lets you get your location only once per run.
  • Privacy is an issue, Firefox asks for permission by showing a notification bar on top of the screen. Click “Tell them” to proceed…

    

  Map your location…

  What the script does…

  // call native geolocation API:
  navigator.geolocation.getCurrentPosition(callback);
  
  // callback initializes a google map with the geo data:
  function callback(position) {
      ...
      var point = new GLatLng(position.coords.latitude,
           position.coords.longitude);
      ...
  }
  

  Google provides a similar Geolocation API implementation through Gears.

  Got another browser where the API works? Please leave a comment!

    Update: indeed, the bug has been fixed in Firefox 3.5b99 – but some requests return a very unaccurate estimate, while others are perfect within only a few meters error.
    I guess in some cases Wifi is used, while in other cases generic Geo IP tables are used (e.g. if the Wifi lookup times out?).

    Doug Turner 03:14 on June 23, 2009 Permalink | Reply

    exactly. if a wifi position is found, that is the location that is shared with the website. if no wifi position is found, a location based on IP is shared.

    Keep in mind, all of this is optional — we don’t share anything until you click “share location” in the notification bar.

    Hope that helps!

    Works fine in the iPhone 3G mobile Safari (OS 3.0) browser, too.

      Cool, thanks!

      It doesn’t work out of the box on Android’s Webkit browser on the G1, need Google’s interface for that apparently.

  Use your blog as shortened URL service 

  

  Image by Duane Storey via Flickr

  I just discovered and installed a very nice WordPress plugin, WordTwit. The main purpose of this plugin is to tweet your new blog posts on Twitter, together with a link to the new blog post.

  So far nothing too shocking new, but the latest version (2.0.x) of the plugin adds the option to use your own blog as url shortening and redirecting service. Think tinyurl.com, is.gd or one of the gazillion alternatives out there.

  Now that is really cool. Except it didn’t work for me.

  Turns out that there was a little bug if your blog is not served off the root or your domain, but a sub directory instead (which is /blog in my case).

  So, a patch (shortened link, noticed?) solved this and all should be set to go now.

  Oh and this post is serving as a test post for the Twitter update…

  Howto: add news section to WordPress Content Site 

  

  It makes much sense to use WordPress for a simple content site, consisting of just a bunch of (static) pages which need to be updated once in a while. For example, I used this approach for the (Dutch) website of Kinderfysiotherapie Den Haag Centrum.

  WordPress gives you a handy-dandy Content Management System (CMS) and there are lots of available templates to base your design on.

  Compared to the default configuration, you need to put some effort in the setup to use pages for the site’s navigation rather than blog posts, but this can be done by setting some options and tweak the menu structure of the template, which is all documented fairly well elsewhere (Customising WordPress – twine).

  Then comes the inevitable moment that you want to add a somewhat more dynamic news section to the site. It makes sense to use the excellent blog system, which WordPress essentially is, but then “inside out“, embedded in a news page rather than the primary site feature.

  There are a few possibilities here, but I settled for the Inline Feed plugin. Once activated, this plugin displays a list of your posts in any content area, with a few configurale options like sorting order and length of title etc.

  Now you can use the excellent native WordPress authoring and publishing system for posts for your news section, with all hidden gems like RSS feed generation, optional comments and all gazillion plugin powered extras.
