A reader once asked me if I could build a command line tool which takes title from one file, and content from another file to create wordpress post. I tried, which finally gave an outline to this script. I dont think that this is very high fly, but for those whom the xmlrpc is mumbo, this might be somthing worth looking into.

Recently I got fed up trying to convince the operators of a client, for whom we had implemented a wordpress site. The operators, even after we repeatedly asked to upload only relevant sizes for certian positions, were trying to make one size fit for all. Hell, places where thumbnails of 1 to 2K would suffice, were being used up by 30K images, resized by our theme constraints. We were running wordpress on lighttpd.

Pretty simple, really. Adds a new type of feed you can subscribe to. Simply add ?feed=json to anywhere you get a normal feed to get it in JSON form (but with a cutdown version of events).
Version 1.1 added support for JSONP. To get a JSONP response instead of a normal JSON structure, simply add jsonp=callbackName to your query, where callbackName is the name of the function to be wrapped with.

After about an year, since we launched Asianet News Portal the home page with all the complications had started to show a dead slow performance, and by using our Query Profiler, I could identify the bottleneck as the number of queries, and wordpress itself was telling the status as 48 queries in 6.344 seconds. Now this was a whopping value, and when the latency of 2 to 3 seconds is added to this, the initial html load would be in 9 seconds. Making the total site complete load in about 53 seconds. One can imagine the agony I was feeling, after all the work I had done to get backlinks, and if users who are visiting the site is just running away without waiting for the site to load, then I better not run the site atall.

Once we achieved 20K visits per day at asianetindia.com (maintained by Saturn SPL), we planned to hammer in and our target was 30k in three months. We have achived that view the stats. For this twitter and blog helped a lot. We had added auto blogging, and wordtwit both to the existing asianetindia.com. It means each post when published will be tweeted, as well as a post to blog, which contains the excerpt with a back link to the original.
We wanted to get maximum links back into the blog also, and thought that a track back would be the best method and choose that against auto commenting systems. And a full time tester was doing linking related news and posts from other sites to our blog posts. It started to turn tiring when thought of the volume that was getting posted in a day. At this point, we at saturn started to think of automating the linking drive. The out come is autolinker, which is run using the random cron.

Recently on Kerala News by Asianet, though the wp-simple-tags was there, the posts were not being tagged automatically. And on a detailed check I found it was due to a misconfiguration, and once the same was done properly the tagging started smoothly. But already a set of 8K posts were there with no or unrelated tags mistakes and un awareness of the operators who were posting to the site. Now I wanted these to be tagged properly.
I had already used the word-twit plugin and done some mods to the same, so it was more eaiser for me. Just went through the original code of word-twit and salvaged a small script which is attached here with as download.
require_once( dirname(__FILE__) . '/wp-load.php' );
The code above loads the wordpress system and initializes the wp variables and connects to the database.
global $wpdb;
Makesure we have the database abstraction object from wordpress, to select the posts, and do all the required manipulations on the same.
require_once( ABSPATH . 'wp-includes/class-snoopy.php' );
Include the inbuilt snoopy class, to mimic a web browser with the most simplicity.

While trying to speed up Select Articles, I got stuck, torn in between WP Super Cache and lighttpd. Already we at Saturn are using lighttpd on several dedicated servers, and know the potential and benefit of having this over Apache though the flexiblity of having a perdirectory configuration at the programmers choice was a big question. A quick search on the Google landed me to a technical blog, notepad and personal web page by Asterios Katsifodimos.
Trying to get WP Super Cache & Wordpress working on my fast lighttpd server, I came into problems, mainly because of lighttpd’s lack of (Apache’s version of) the mod_rewrite module. The static files that were created from the cache were not statically served from wordpress. The problem is that in order to use them, the PHP fcgi was called for each request. So, why would we have to call PHP every time that a file can be completely statically provided by the web server?

We were worried, about all the comments on kerala online, being marked as spam by the akismet plugin. When on detailed examination, we found that the basic problem was that wordpress was logging only the immediate downsteam ip as the remote address, well ours was a bit confusing setup, but to handle the traffic we needed it that way.
A search for wordpress behind reverse proxy, landed me to the wordpress support page. In fact the 5th entry on that page is done by Gopka, who is the lead on this project from Saturn.
We started to correct the remote address by overriding the global variable making slight changes to the wp-config, such that we will not accidentally overwrite the changes while upgrading wordpress. Well the code
if(isset($_SERVER['HTTP_X_FORWARDED_FOR'])) {
$list = explode(',',$_SERVER['HTTP_X_FORWARDED_FOR']);
$_SERVER['REMOTE_ADDR'] = $list[0];
}
when added to the wp-config, it started to log the first IP, and that would be mostly private IPs if the request was from organisations where internet was shared through proxies or using NAT. The case was same at our office, so we had to find the first public ip from the list of IPs and the code for function getIpBehindProxy was the out come.

During the past couple of months, since we are maintaining a heavily loaded wordpress implementation, Kerala News Portal for Asianet, distributed across two servers, and having a daily visit of 50K, I was on the hunt for better caching and optimizing techniques. On the move, I happened to read the article by Jeff Starr, written some 15 months ago, and all the associated comments. It was sad to see that the file based cache was removed from wordpress, due to several reasons though.
After reading through this, I saw the official Function Reference for WP Cache, and the eAccelerator for WordPress by NeoSmart Technologies. Reading through the code written by Computer Guru of NeoSmart Technologies, tickled me and I just modified some parts, by pulling out the eaccelerator specific functions, and switching to a file system based store. I am not adding the code as pretty php code. Drop the file into wp-content, create a cache folder in wp-content and chmod folder to 755.

After reading about Website Performance Tweaks, and a lot of other blogs and slides, I thought about how to cook up a javascript aggregate plugin for wordpress. The out come is wp-jsmin. Though this is in its infancy, it is being used in this blog, to combine all linked javascript to a single link, thereby reducing server requests. This code is still in the testing stage, and may break if the used scripts do not pass lint checks. I am planning to shift all the options to a options page in the wordpress admin page.
Those who are daring enough could download and try. Please put a comment here if you are using this on your wordpress. And for others who would like professional help, I would be most pleased to extend my services through RentACoder. Or for a whole dedicated wordpress team to design, build and maintain sites like Kerala News, Asianet Cable Vision: Corporate Site or Campagin Portal for Shashi Tharoor, send an inquiry to Saturn.
