planetOzh http://planetozh.com/blog A bit of my personal life, mainly focused on my kids. A bit of code, mainly focused on Wordpress and PHP. Overall, bits of nothing in particular. Tue, 07 Sep 2010 16:56:28 +0000 en hourly 1 http://wordpress.org/?v=3.0.1 50.99012.1413http://creativecommons.org/licenses/by-nc-sa/2.0/http://planetOzh.com/http://planetozh.com/images/feedicon/feedicon.phpplanetOzhplanetozhhttp://feedburner.google.com Spam Magnet Blog Posts http://feedproxy.google.com/~r/planetozh/~3/RU4Pxts0J5o/ http://planetozh.com/blog/2010/09/spam-magnet-blog-posts/#comments Mon, 06 Sep 2010 15:18:01 +0000 Ozh http://planetozh.com/blog/?p=1498 Lately, every time I manually flagged a comment as spam, I started to have the impression that they all were posted on the same post, namely an old announcement for my plugin "Absolute Comments".

An SQL query later, my impression was confirmed: this blog post *is* a spam magnet:

I suspect that some particular keywords in page titles act like pheromones to spammers. These keywords probably include "comments", "guestbook", "feedback" and anything that will make them think there's a form they can spam.

The SQL query I used to list blog posts sorted by the number of spam they get is:

PLAIN TEXT
SQL:
  1. SELECT COUNT(wp_posts.ID) AS spam_count, wp_posts.ID, wp_posts.post_title
  2. FROM wp_posts, wp_comments
  3. WHERE wp_comments.comment_approved = 'spam' AND wp_comments.comment_post_ID=wp_posts.ID
  4. GROUP BY wp_posts.ID
  5. ORDER BY spam_count DESC

If you want to play with it, I made a quick standalone script that will run the query and output a pretty interactive pie chart. Download spam-magnet.txt, rename as .php and put it in your blog root (where wp-load.php is)

If you run it and notice a pattern on your blogs too, share your analysis! I've always enjoyed useless fun stats :)

You Will Love This. #plugindevbook http://feedproxy.google.com/~r/planetozh/~3/T9aAWFoBQbk/ http://planetozh.com/blog/2010/09/into-plugins-you-will-love-this-plugindevbook/#comments Wed, 01 Sep 2010 14:00:30 +0000 Ozh http://planetozh.com/blog/?p=1490 So, peeps, I have good news and bad news. And by good news, I mean super mega hyper exciting announcement.

The good news: three persons, carefully handpicked among all the three most important people in WordPress, are writing a book, I mean, THE book, on WordPress Plugin Development. These three fine chaps are Brad Williams, Justin Tadlock and me.

Let me rephrase this in a way that will more reflect my state of mind and how I think about this. OMFG I'm writing a fucking book!!!1!!one!!eleven

Ozh' State of mind (allegory)

The book, entitled "Professional WordPress Plugin Development" (yeah, my suggestion of "Pluginz That Pwn" didn't make it through) should hit shelves in March 2011 and will be published by the cool geek lovers from WROX, in the same collection as Brad's "Professional WordPress".

Not only this is a super author team, but also we'll be lended a hand by a top notch Technical Editor, an incredible guy who is a bit more active than hyperactive kids drinking coffee on steroids, who blogs, commits, speaks, twitts and never sleeps, also known as Andrew Nacin. His role will be to crack the whip and molest us when we write dumbities and acting like we actually know a thing or two about a thing or two (which should happen more than he hopes)

So far the project is running great and what we have written already is, hmm, let me carefully pick an appropriate word, I'd say, like, awesome.

In the next few months be sure to follow @Brad, @Justin and @me for some cool info and exciting news about the book and how we're doing :)

Oh, and the bad news: I have a fracking sprained index finger on my right hand. Which means I can kiss good bye my 60ish WPM, precisely when I have to write pages as if they were raining. Bleh²x100.

A lot of fun stuff, some clever stuff, various languages.

Here are a few of the best things I've found and could understand (I did have to Google a few hints sometimes, I feel like I lack a bit of classical movie culture:). Some are duplicate titles with different source code. A few obvious, some quite smart. Can you guess them all?

Over the recent months, a site that can make you big money has really found its audience, from a clever promising idea to an active community of users. I've already mentioned it when it started, and I mentioning it again now because it is getting big: WP Questions.

If you don't know this site, the theory is dead simple: people ask questions and disclose the little amount of money they're willing to offer, experts answer and hopefully win the cash if their answer gets selected.

Since its debuts, the site has gained real traction and what used to be cheap ass $3 questions are now much more interesting little gigs. Interestingly too, there are now coders who completely offloaded their support to WP Questions, such as Ronalfy with his WordPress and Ajax ebook.

Now, for the catchy headline: over the last week, the total amount of cash offered in questions has surpassed $350, with an average nearing $20 per question, and I suspect the trend is on the rise. Of course, it's uncertain you alone will snatch all the money with best answers each time, but that is a very decent pocket change source.

To catch on, be sure to subscribe to the numerous feeds the site offers, or even better, follow @wpquestions. First answers are usually damn fast (under 3 minutes) but the quickest does not always gives the best answer.

Through the 54 releases to date, WordPress has grown from an immature toddler to a big healthy kid. The following graph shows the evolution of the zip archive size and the total uncompressed size:

In the early days, in was rather cumbersome to download locally a .zip file, uncompress it, then upload the whole stuff to your server. Now that there is a built-in upgrade, the total size of the baby does not really matter, since everything takes just one click.

What's noteworthy here is that there seem to be a 3 MB limit for the zip to ensure the core upgrade works on most hosts (see issue raised during the making of WP 3.0). So, unless something changes in the way the WordPress upgrader handles new releases, we are nearing the glass ceiling.

You can obviously correlate the total size with the total number of files, and with the evolution of the number of built-in functions (see previous post). Again here, I would have thought the biggest increase would have been with the WP/WPMU merge in 3.0, but it's not. Anyone remember what was so hefty and new in 2.7 and 2.8? The file system? The inclusion of Simplepie to deprecate Magpie?

We're now at almost 9 MB (uncompressed) and 756 files, but what files exactly? The increase of the number of PHP files is pretty stable, while Javascript files population really grew in the recent versions. I think the jump with the 2.8 release again might be the inclusion of both .dev.js uncompressed files and their minified .js version.

To conclude this incredible piece of academic research, a few one liners:

PLAIN TEXT
CODE:
  1. # total size of each wordpress-[version]/ directory
  2. du -s word*
  3.  
  4. # total number of directories
  5. for DIR in word*; do find $DIR -type d | wc -l ; done
  6.  
  7. # total number of .XXX files
  8. for DIR in word*; do find $DIR -type f -name "*XXX" | wc -l ; done

And, for the curious, the complete data.

  • The latest version of WordPress, 3.0.1 as of publishing, has 3240 PHP functions defined.
  • The first version (0.7.1) had 309
  • Across all WordPress versions, 3920 PHP functions have been defined and used
  • On average, each ".X" release (2.1, 2.9...) introduces 225,2 new functions
  • Only one release went on a diet: version 1.2.1 had 23 functions less than its predecessor, version 1.0.2

Have a look at my Excel mad skillz showing the evolution of the total number of functions defined in WordPress:

The following graphs shows how many functions have been added (ie functions added minus functions removed) in each version.

To my surprise, the biggest evolution has been in WordPress 2.8 ; I would have predicted that the inclusion of multisite functions in 3.0 would have a larger impact.

For the curious and nitpickers: data sheet used.

This said, there can be situations where you need to backport something, or to make sure it will work with both older and newer versions of WordPress. If you happen to be in a situation like this, good news fella: I've just updated my handy WordPress Functions Implementation History Tool, which lets you know when a particular function was introduced in WP (or removed from WP if applicable). The tool comes with a full list of all 3920 functions that existed through WordPress' history in various formats. Enjoy!

No more entering your login/password, but a more secure OAuth system that redirects you to Twitter's site and confirm you're allowing access to your account. All this, honestly, kind of sucks.

The good news: I've updated my YOURLS: WordPress To Twitter plugin to now support OAuth, as well as a lot of other improvements. Go check it now! Update and play, you've got 8 days to return feedback if something is not working as you were expecting :)

Speaking of YOURLS, version 1.5 is coming along nicely. No, no ETA. Check out this screenshots: YOURLS interface (notice a new menu?) and, as an example of a bundled plugin, a "social" toolbar. The trunk version, labeled 1.5-beta, is stable enough if you want to play with it (I've been using it for weeks now). Join the fun and code some plugins!

I could not miss the opportunity for a silly plugin. After a quick web search for images and sounds, here it is. Meet the Vuvuzelator, yet another plugin that will make your blog pay tribute to the real star of this World Cup. With image and sound. Oh my, sound.

I knew Ronald can craft good things (you've read stuff from him on WLTC) so I was curious but, hey, a whole book just about Ajax?

Five word review

Did not waste my time!

More than five word review

The ebook clocks in at 252 pages of a rather unusual format (15x21 mm or A5). Not sure if this is to be more convenient when printed or to be faster to read :) The layout of the book is pleasing, colorful and attractive. One excellent point: all code snippets are syntax highlighted. This makes reading code much easier and should be *mandatory* for all ebooks (not to mention blogs and any online media, of course). My only gripe regarding the format is that the rather small page width induces quite some line breaks in code blocks.

The first chapters of the book cover the Ajax basics: properly adding Javascript into WordPress, how to internationalize the scripts, a short introduction to jQuery, why and how to pay attention to security.

After setting the foundations, the book goes through three very detailed examples of real world applications, ending with a fairly complex Paypal Buy Now button and associated Coupon codes.

Reading the book is actually kind of fun and not boring for a second. The writing style is casual yet accurate, a bit like attending a very detailed and sharp conference, where you get a glimpse of the author's personality as well as a bit of his knowledge.

As in everything related to coding, there's more than one way to do it, and the book shows a few, from quick hacks that will do when working on a client's site (case in which you know what environment you're working in, the paths to directories etc..), to working on a plugin that will be run anywhere.

In short, the book introduction itself is pretty accurate:

The goal of this book is to provide you a rock-solid foundation for using Ajax with WordPress. After the foundation has been laid, you will be walked through several real-world examples. By the end of the book, you should not only have a thorough understanding of Ajax, but how Ajax functions within WordPress itself.

This book is for people who want to take time to understand how to build things, through step by step examples, rather than for people who want a quick cut and paste snippet. Given the amount of things you'll learn if you're willing to, I think its price ($24) is quite a bargain. If still unsure, there a sample chapter for you.

Disclaimer: no affiliate code use here, I say I like the book because I do. If you want to buy it through me, feel free to use this link.
