WordPress: External RSS Feeds Optimization with KB Advanced RSS

ageor — Wed, 22 Apr 2009 19:00:10 +0000

Apart from its own Ice Tea tech blog, Dipot.com also displays two external feeds relating to Optimization and Standards. I needed to optimize the post titles of these two feeds by getting rid of their long suffixes, both for better looks and for more content within the same space.

The feeds were served by the standard RSS WordPress 2.7.1 widget, which is fine, except it does not support much customization. After some search, I found Advanced RSS 1.0.1 WordPress plugin and KB Advanced RSS 2.1.3 WordPress plugin. Smart RSS only works until WP 2.7.0 and I didn’t want to tweak with that. Advanced RSS only works until WP 2.6.2 and requires PHP5, DOM and XSL extensions loaded on the server and I don’t want to depend on those if I don’t need to, so the choice was easy.

Installation of KB Advanced RSS worked flawlessly right from within wp-admin. Then, on my first attempt to configure it, I came across a problem which could very well had been a show stopper: for some reason, except for the feed’s URL and Title, the widget would not commit any of the other parameters to the “Options” table of the database. Troubleshooting this issue, I ended up reading all the users’ comments on the plugin’s site. As usual, I was not alone; this is a common issue. Thankfully, Wesley of http://www.improvingtheweb.com had already posted the solution to PHP4 not committing widget field changes in WordPress. The solution worked like a charm. And, as expected, when I later upgraded to PHP5 the problem wasn’t even there to begin with.

KB Advanced RSS is well thought-out, very straight forward with good documentation and examples. It supports all the features of the standard widget (including multiple instances) plus formatting and full support of all the feed’s fields to display or not (including the debugging tool to show which these fields are)! It further supports two modifiers to optionally manipulate the string before display, by taking out a number of characters from the start (ltrim) and/or trimming it to a specific length (trim).

Alas, what I actually needed was to take out a number of characters from the end of the string. Fortunately, as it turned out, KB Advanced RSS’s code is pretty straight-forward and extending it with my own modifier (rtrim) to do just that was only a matter of 3 lines of PHP code added to the version of the plugin that runs by my version of Wordpress; there’s one for versions up to 2.7 (pre-wp-2-7.php) and one for versions after that (post-wp-2-7.php). Here is the PHP code from the modified post-wp-2-7.php (my rtrim extension is in blue):

///////////////////////////////// CUSTOMIZATIONS /////////////////////////////////////////
/////////////////////////////////////////////////////////////////////////////////////////////
// If you want to write customizations, put them here. The variable to modify is $text. See the FAQ.
/////////////////////////////////////////////////////////////////////////////////////////////
/////////////////////////////////////////////////////////////////////////////////////////////

// right trimming
// cuts $rtrim characters from the right
// by ageor, April 9, 2009
$rtrim = (is_numeric($rtrim) && 0<$rtrim) ? (int) $rtrim : null;
if (is_int($rtrim))
$text = substr( $text, 0, strlen($string)-$rtrim );

// left trimming:
$ltrim = (is_numeric($ltrim) && 0<$ltrim) ? (int) $ltrim : null;
if (is_int($ltrim))
$text = substr( $text, $ltrim );

// length trimming (do after left trimming)
$trim = (is_numeric($trim) && 0<$trim) ? (int) $trim : null;
if (is_int($trim))
$text = substr( $text, 0, $trim );

return $text;

The way this is written, the string in question can undergo any mix of all three trimming types necessary.

All setting up and troubleshooting took place by adding one instance of the widget and configuring it, then a second instance. When all was done and I had what I wanted, I removed the original two instances of the original RSS widget, positioned the new ones on top and saved, certain I was done. However, as the resulting “Widgets” Wordpress admin page suggested after saving, something was very wrorg. It displayed the message ‘You are using 3 widgets in the “Left Sidebar” sidebar’ but not the widgets themselves, nor the “Save Changes” button. Sure enough, I ended up with an unworkable site, as these where the first 2 widgets on the left column of Ice Tea tech and the page that appeared ended with the title banner. Disaster!

To cut a long story short, plenty of “trial and error”s later and with the help of Vicki of neTWire, here is my conclusion: For KB Advanced RSS widget to work with WP 2.7.1 and the Atahualpa WordPress theme, the WordPress RSS widget needs to be activated and positioned above it. That’s how I temporarily solved my problem, until (if ever) I have the time to look deeper into the code involved or newer versions of the theme and/or the plugin solve it for good.

Just to be clear, none of the problems and troubleshooting it took to solve them can be traced back ato KB Advanced RSS alone. Atahualpa is a great but complex theme and it is their combination that turned out to be problematic. It’s not the first example of a bad mix and it won’t be the last. On the flip side, with each such incident we get to learn something new that will potentially save others and ourselves some frusrtation and time in the future.

PCs and the Internet: Addiction Magnets or just Tools?

ageor — Sun, 05 Apr 2009 20:44:38 +0000

The traditional Media (at least in Greece, where I live) don’t treat computing nor the Internet right. I don’t know if it’s because of ignorance or because they feel threatened by it. However, I do get the impression that, most of the time, when radio, TV or the press mention PCs and/or the Internet it’s because of a child pornography site, computer fraud or how young people are getting addicted to it.

According to WikiPedia’s “Addiction” article: “… The term addiction is also sometimes applied to compulsions that are not substance-related, such as problem gambling and computer addiction. In these kinds of common usages, the term addiction is used to describe a recurring compulsion by an individual to engage in some specific activity, despite harmful consequences, as deemed by the user him self to his or hers individual’s health, mental state or social life. …”.

I’ve had various discussions with intelligent people who are not well acquainted to computers nor the Internet and they express concerns about its use and hidden dangers in it, especially if they are parents. The concern that “kids, teenagers or people who use their, usually networked, PC for long hours are addicted” is overrated and exaggerated.

From Wikipedia’s “Internet addiction disorder” article: “… To the extent that the Internet is a social medium instead of an object, people cannot be addicted to it. The analogy is made to an environment: a person can not be truly addicted to living in a favorite town (no matter how distressing a change of home might be), and a goldfish can not be addicted to living in a pond.
Secondly, it is widely recognized, even by its supporters, that most if not all “Internet addicts” already fall under existing, legitimate diagnostic labels. For many patients, overuse or inappropriate use of the Internet is merely a manifestation of their depression, anxiety, impulse control disorders, or pathological gambling. In this criticism, IAD is compared to food addiction, in which patients overeat as a form of self-medication for depression, anxiety, etc., without actually being truly addicted to eating.
It is possible that a person could have a pathological relationship with a specific aspects of the Internet, such as bidding on online auctions, viewing pornography, online gaming, or online gambling (which is included under the existing Pathological Gambling), but that does not make the Internet medium itself be addictive. …”.

People spending way too much time “in” the Internet is a misconception dated back to the time we needed to dial-in to the Internet. While connected to the Net over telephone lines the meter was running, hence the need to make the most out of it. Broadband has changed this. We are now “online” all the time for a flat rate, or, at worst, for a pay-as-you-go rate (especially true in cellular telephony). In these early days, we got online specifically to use the Internet, mainly use email, surf the Web and, if advanced enough, to do some instant messaging and e-shopping.

Today, thanks, in part, to digital convergence and the computer becoming a consumer item, we have one PC each instead of one per office or home and we do online pretty much anything we did before the Internet existed at all. Thanks to broadband, the phrase “I am connected” doesn’t mean much any more, because we are online whether we actually make use of the Net or not. Sometimes we are practically online and we don’t even realize it (most high end cellular phones are a click away from the Internet)! We have blended it in our everyday life like the telephone, the radio, the TV, the newspaper, the typewriter, the tape recorder etc. before it.

Except for physical activities (debatable; have you tried Nintendo Wii Fit?), computers, possibly connected to the Internet, are used today for prety much everything else. Today, even more than in the earlier days, neither computing nor using the Internet are activities by themselves. They are just enablers for countless individual activities (the following is by no means a complete list, or in any particular order):

Reading, Watching, Listening to Multimedia Documents
Reading, Watching and Listening to our own or others’ material includes art, essays, news, books (electronic and audio), presentations, schematics, photos, music, videos, radio & TV broadcasts, podcasts, etc. or any combination of those and more.
Research
Whether it is scientific or market research, online computers are the tools behind it that collect, store, index, process, search, retrieve, distribute and present all the information and data in ways limited only by imagination.
Multimedia Documents Creation
Most (or all?) of this so-called “content” we can view, we can also create ourselves for us and others to view or use.
Communication & Social Networking
Email, Instant Messaging (IM), VoIP telephony, Video calls, Audio & Video Conferencing are just some types of online communication. Social Networking helps keep in touch with lots of people. Additionally, (micro)Blogging and RSS feeds help us get input from and address potentially unlimited content creators and audience, respectively.
Recreation & Games
Physical activity aside, electronic editions of traditional board games represent only a small fraction of the games we can play with practically unlimited human or computer opponents from around the globe.

It’s not my intention to prove how good technology is; there may be issues in all applications that leave room for discussion. I am trying to raise awareness to the fact that computer and Internet usage cannot be measured as an activity on their own, as they are not. They represent the sum of all their individual uses. Of course (networked) computing (possibly as life itself) is a platform where addictions can occur. Like all drugs are not inherently addictive, nor is technology, computing or the Internet. Still, ‘… With the widespread use of computers in the 21st century, it may be difficult to distinguish users who are “highly engaged” in their computer use from those who might be considered “addicted”. …’ (from Wikipedia’s “Computer addiction” article).

Diversity and multiple activities & interests have always been factors against addictions. Having a tools combination like a computer networked to the all-inclusive Internet actually promotes diversity. Let’s do so, too.

PS. There are studies indicating computer and internet “addiction” or “overuse”. At this point (and I am no expert), I believe many people use or overuse them like they do with any new, shiny toy. Once they both become commonplace, like the telephone and television did, any “related” addiction will be easily traced to the pre-technology causes.

7 Favorite, Value Adding FriendFeed Applications

ageor — Thu, 22 Jan 2009 17:09:48 +0000

I like FriendFeed much better than Twitter; that’s no secret. In a conversation with @Trianta earlier today, it seems the only FriendFeed desktop clients out there are the Adobe Air-based Twhirl and feedalizr. They both leave a lot to be desired. There is also the announcement of .NET-based FriendFeed Client. Web-based FriendFeed applications are also scarce, compared to Twitter’s.

This isn’t a wish list. It’s a wish come true list, including existing applications that accomplish specific tasks and add great value to FriendFeed. True, there are many more than the following but those are my favorites (in no particular order):

Friendfeed Like Compatibility Calculator

FriendFeed stats only show 10 people who like me and another 10 that I like most. It’s not enough. Friendfeed Like Compatibility Calculator lists who gave a user the last 300 likes. Utilizing the 3 included modifiers, the list can show people with similar interests. It also shows the subscription status with a small “sub” next to each user. No password or passkey is required.

FriendZone?

Find out the top 100 subscribed to people among the people you subscribe to. This defines your friendfeed neighborhood, or FriendZone and results to contacts you may want to subscribe to, if not already. No password or passkey is required.

FriendVenn

This is one function FriendFeed should perform itself. FriendVenn answers who subscribes to you that you don’t subscribe to. Only for oneself, as it requires both username and password (not passkey). It returns 3 columns: “people you are subscribed to”, “people who both sub to you and you sub to” & “people who only subscribe to you” with totals for each.

Twitter2FF

Twitter2FF helps sync Twitter follows and FriendFeed subscriptions both ways. It requires usename/password for Twitter and username/passkey for FriendFeed. It then provides a one-page, one-click per user interface to invite or subscribe to Twitter friends in FriendFeed and follow FFd Friends in Twitter. It uses its own expanding database of Twitter-FriendFeed account pairs, as well as the Twitter feeds of people you subscribe to in FFd. Friendfeed recently added its own support to massively Find (and subscribe to) your Twitter friends on FriendFeed but Twitter2FF is still useful for the other half of the job.

FriendDeck

FriendDeck runs different concurrent FriendFeed searches live. Each result includes all poster’s details, the originating service and Like, Re-Share & Link ability.

FriendFeedLinks

“FriendFeedLinks is a memetracker that tracks links shared on FriendFeed”. It also makes them available via RSS.

ffholic

ffholic reports (collectively or per user) on the most Discussed, Liked, Commented, Popular or Active Entries, Users, Rooms, Photos, Music or Videos (not all combinations exist) for the last 1, 7 or 30 days. The good thing is Entries, Photos, Music & Videos reports are available in RSS feeds and include a language filter, powered by Google. Last but not necessarily least, ffholic also presents user metrics and calculates “activity points”.

Find more in FriendFeed Apps and, please, let me know of other FriendFeed apps, clients etc. that you find useful. There is also Robert Scoble’s discussion “To new friendfeeders (there are thousands due to Twitter invites and follows), here’s what you need to know:” on Friendfeed, with plenty of tips and links.
