Locking Down WordPress is a book by CodePoet featuring Rachel Baker, Brad Williams, and John Ford. If you want to know why and how WordPress sites get hacked, and a handful of tips on how to prevent that, this free book is an awesome place to start. It’s quite short and even has a TL;DR section for those of you who are busy.
Hope you remember the Quick Flickr Widget plugin for WordPress. Well, since version 1.2 I’ve changed the way it works. Prior to 1.2, as Donncha suggested in his Flickr plugin, I used a public Flickr RSS feed to display the items, using WordPress’ RSS functions to move around the feed. Anyways I thought that I couldn’t take the plugin far enough, so I decided to use the Flickr API Services which is way more extended.
Still not sure about the consequences of sharing my Flickr API key. I’ve got a Flickr call for converting a Flickr screen name to a Flickr NSID which requires a valid API key. I thought that asking everyone to sign up for an API key would be a loss of plugin users so I provided my own key. Hope they don’t get me killed ;)
Now, to the user interface and experience. I’m not sure why, but some people are still confused about the new way and there are those, who cannot manage to find out their Flickr screen name (thinking that it’s their Flickr username or Yahoo ID). Anyways I hope to get this all sorted out and solved by 1.3 (maybe I should feed from Flickr by user e-mail?). Tiny bug in 1.2 was the inability to use a Flickr screen name with spaces. Thanks to Tung’s comments I sorted it all out by 1.2.1 – I had no idea people would use spaces in their screen names.
Also, I’d like to recommend a book called Pro Web 2.0 Mashups which helped me out with Flickr API usage.
Finally, I got the book about Remixing Data and Web Services and read about 3 chapters. It seems that everyone is already mixing up all kinds of data from sources like Google Maps and News, Flickr photos, delicious bookmarks, last.fm charts and others. The very first mashups like Housingmaps.com are brilliant, and with Yahoo! Pipes coming along, things seem to get much easier for people without any coding basics.
The Yahoo! Pipes service is a feed aggregator and manipulator, that lets you remix feeds from multiple sources. And many many more seems to be on its way :)
And here’s a quick tip about linking to Amazon books. Find the book you like through Amazon search, go to its Product details and copy the ISBN-10 field value. The shortlink for your book will look like this: amazon.com/dp/159059858X, where 159059858X is the ISBN of the book. Nice huh?
