AJAX and CSRF

WordPress, , ,

When working on some new AJAX features for bbPress and WordPress we’ve noticed that AJAX requests don’t seem to send HTTP_REFERER values. We check referrers as one level of protection against cross-site-scripting, or XSS, so when they’re not set we aren’t able to use that value. How are most people using AJAX protecting against XSS? It seems the same things we’re doing to make things easily accesible in a dynamic fashion are also opening new vectors for attack.

New WP.org Search

Open Source, Search, WordPress

At the last IRC meetup the WordPress community asked for better search that included both the forums and the Codex and was integrated with the look and feel of the rest of the site. When I did this before it was horribly slow and it involved several queries across several different programs and MySQL hosts to get the results from the wiki, the forums, the blog, and then splice them together somehow. Later we switched to a plain Google site-search but they didn’t like the HTML we used for the search form so we took it down. Well after the meeting I remembered Yahoo Developer Network which had some sort of API for their search with a much higher limit than Google’s.

I went to the site to see how much of a pain it would be so I could start properly procrastinating, but I was taken aback by how incredibly easy it was to get an application ID and start getting the results back as simple XML. I began hacking on it right then. It was about 5 minutes to set up a search form with URIs the way I wanted, 7 minutes to get the XML and parse it out, 5 minutes to write in some paging, and then about 20 minutes tweaking the search page to make it look a little better. The result is the new search.wordpress.org WordPress Search.

It still needs some more work. There seems to be a dupe problem, which is actually a problem with our site, not Yahoo Search. I’d like to tweak the results to highlight newer topics more, or at leats allow for a date-based weighting. Finally I think it would be nice to include some WP-related blogs like Blogging Pro and Weblog Tools Collection in the results. Most importantly we now have a clean URI structure and home for searches which is abstracted from any piece of software or particular service provider. Yahoo deserves major kudos for opening up their information in such a free way and making it so easy that it’s taken me longer to write this post than start using their API.

Pulse of Freedom

WordPress,

“The Pulse of Freedom is a site published by the protesters at Martyrs’ Square, Beirut, from a tent city.” This is an inspiring story: “A group of Web masters, graphic design artists, writers, and photographers stayed up all night for several nights in a row putting the Web site together.” They chose WordPress. “As far as I’m aware this is the first Web site of its kind anywhere in the world. The leaders of a democratic revolution are openly blogging about their experience from the center of the action.” Echoditto writes about their part in Blogging from Beirut. “I am writing this post from a tent city in the Martyrs’ Square in central Beirut, a place which is filled with the energy and excitement of a burgeoning democratic movement.” Hat tip: Mike Carvalho via email.

Back Online

WordPress

I called my sister last night to tell her about a present I found for her in the market and she interrupted me to say she saw my name show up in Google News a few times and started reading some of the articles. Before the phone card ran out she read me some headlines and my stomach sank. This is my first vacation and I almost didn’t even bring my laptop. (Luckily I talked myself into bringing it to do pictures.) I haven’t been on the internet since Monday and I obviously have a lot to catch up on. It was almost midnight when I found out and there was no access anywhere, so I woke up at 4:30 AM this morning to catch the first water bus to the airport and found some overpriced wifi, and here I am.

I have close to a thousand emails and countless blog posts and comments to go through, but I’ll try to synthesize everything and respond ASAP, I think it’s important because some people seem to be spinning things quite maliciously. If you have a specific question please send me an email and I’ll do my best to respond personally or on the blog, even if you’ve already decided I’m the scum of the earth.

WordPress and Dreamhost

WordPress

As has been reported many places, and sent to me in a dozen emails, Dreamhost have integrated support for installing and upgrading WordPress through their administration interface. For many this is not new, some systems like Fantastico have had support for auto-installing WP for a while now, but the interface was cluttered and WordPress was just one of several dozen miscellaneous scripts. What’s really interesting about this decision is their thought process, quoted from their newsletter:

Why didn’t we make it so you could just install Movable Type itself with one click instead? Somewhat because Movable Type is a commercial product, and they would require us to do some sort of weird registration for all our users with them in order to even install the free version. Also, WordPress doesn’t require “rebuilding” your blog every time you publish. Mostly though, installing WordPress was eleven times easier for us.

Tyler Brekko sent me screenshots from the entire installation process, including emails from the “Happy DreamHost WordPress Robot” and it’s kinda neat. They take advantage of a few structural decisions in WordPress and on wordpress.org to make the process very smooth. You can read a bit in their knowledge base. What surprised me the most was the sheer number of people who emailed me about this, DreamHost must have a ton of users. Here are some other posts around the web about this:

Thanks to everyone who wrote in about this!

Houston Press and CNET

Personal, WordPress,

(Also known as Announcements Two and Three. See part one.)

Matt Mullenweg may be underage, but he knows how to get into a bar.

That’s the opening line from the Houston Press feature called The Blog Age, subtitled “Matt Mullenweg helps usher in the real information revolution, one Web log at a time.” Modest, eh? It should be on newstands tomorrow so if you’re in Houston pick up a copy. Otherwise read it online.

Though it’s a little embarassing for me in parts, it’s a really good article that covers everything from Open Source to my fellow H-Town bloggers to political blogging at the national conventions. I’ve been talking to Cathy (the author) off and on since August and the strangest thing is how much has changed since we first met in a small coffee shop in Montrose. There are a few points I’d like to expand on or clarify but I’m exhausted from today’s travel right now.

The Other Big News

If you’ve read the article already you’ll notice that it breaks a juicy tidbit that hasn’t been published before: I’ve accepted a job with CNET Networks. That’s the reason I’m moving to San Francisco. There were a lot of ways things could have gone and honestly I wasn’t even planning on leaving Houston originally, but over the course of the past 3-4 months I’ve been talking to CNET and an opportunity came up I just couldn’t pass. As it says in the article part of what they’re paying me for is working on WordPress just like I do now. The rest of my time I’ll be working on various projects, most of them probably so top-secret I can’t breathe a word in advance.

The reason I’m excited about working with CNET is how what I’ll be doing meshes with my thoughts and ideals regarding Open Source, standards, and communities. My principles aren’t changing just because my paycheck is. You can expect the same sort of content here on PhotoMatt.net you’ve seen in the past — namely unfiltered personal thoughts, jabs, and observations not connected with any corporate entity. This is obviously a pretty significant move for both myself and WordPress so I’ll do my best to entertain any questions you may have in the comments.

1.3 Cleanup

WordPress

A few comments about some of the code changes in 1.3. Very nice to see people appreciating some of the hard work we’ve put into this iteration. In a perfect world we could stop the clock and rewrite large portions of the code from scratch, but that would take a long time and break a lot of things in the process. All programmers want to do this, it’s our weakness, but every time I get this urge I think of Netscape and how devastating their rewrite downtime was. We’re making some substantial changes but doing it gradually while introducing new features and responding to users needs.

For example, in 1.3 “the loop” is called very differently but it’s completely backward compatible with everyone’s 1.2 loop code. We deprecate things over time so any structural changes that need to be made come gradually for people upgrading, there’s nothing to drastic every time. This also saves a huge amount of time in support. (Regular users don’t want to have to redo their templates, hackers don’t want to relearn code they already knew.) Same for the new theme system we’re introducing, it adds a lot of flexibility, radically changing how the front end of WordPress operates (like plugins for templates and styles) but all the new stuff is completely optional. I’ve transitioned most of my custom code into a personal “theme” that makse upgrading a lot easier for me (which is good because I do it almost daily).

Next time you get the urge to rewrite from scratch think about the testing your code has gone through, all the edge cases that have already been addressed, the existing installed base, and how many new bugs you’ll introduce with the from-scratch code.

Bloggers Declare Bore

WordPress

Online Journalism Review writes Bloggers Declare War on Comment Spam, but Can They Win? I’m not sure what that has to do with journalism, but they talk to the same old people and read the same old sites and (not surprisingly) come to the same old tired conclusions. I’m trying to figure it out because I like everyone the article refers to and the article itself is well-written, but it feels very contrived. I think it may be because it draws a lot from blog material a year or more old, and selectively, like the writer had an agenda and Googled until there were enough quotes to fill the space. For example Mark Pilgrim’s blog is called “comment-free” when the entry on the front page for the last three weeks clearly has comments. Is it too much to ask to look at the front page of a blog you’re quoting? The article talks about Blogger redirecting URIs but not about Blogger’s registration aspect. It talks about Typekey but not the PATRIOT act. (Totally kidding there.)

You probably saw this coming from me, but most of all I think it’s silly that they don’t mention a single one of the dozens of other blogging systems that deal effectively with these issues every day. You can’t discuss the Movable Type spam epidemic without talking about people like Molly who tried everything out there including MT-Blacklist to no avail, then switched software and got on with their lives. There is a lot more to the story, but that’s been the conversation over the past year and a lot has come of it. The essence of blogging is communication and comments are here to stay, it’s just a matter of moderation.
