“Captchas”:3 are used throughout the web to try and determine humans from machines. In other words applying a “Turing test”:4. Newly added to the Zoinger comment template, here’s a screenshot to show ya what it’s all about.

Adding the Captcha for WordPress was easy. Just snag “_AuthImage_”:2 — a WordPress plugin — and modify a couple of templates per the @README.TXT@ file. Simple.

I figured that this was the most elegant way to try and block comment spam. Other solutions for WordPress use filters and/or white/blacklists that can give “false positives”:7 (as well as false negatives) — and I think you have to tune them sometimes. Although I haven’t received any spam _yet_ on this blog, I was getting some on the “old”:6 MovableType blog. An ounce of prevention…

Oh, the original @README.TXT@ install instructions were… _terrible_. I updated a version of them specific to WordPress v1.5 which you can find “here”:1.

“Are we not men?”:5

And the run of Del.icio.us posts continues! Obviously, I’m fascinated by Del.icio.us. It’s subtilely and completely unintuitively powerful — a strange combination. Anyway, on to “extisp.icio.us”:1.

bq.. extispicious, a. [L. extispicium an inspection of the innards for divination; extra the entrails + specer to look at.] Relating to the inspection of entrails for prognostication.

p. Translated… extisp.icio.us allows you to create a 2D text “maps” of any Del.icio.us users’ tags weighted by frequency — more frequency equals large font size. Here’s a screen shot for my Del.icio.us “Zoinger”:2 account (I trimmed it a bit so it would fit).

“!/img/delicious_extispicious_tag_2D_display.png!”:6

_Click on image for “live” text map._

On “live” extisp.icio.us pages, the text is clickable. For example, _WordPress_ in the image above leads “here”:3.

extisp.icio.us can also create a mosaic of images from Yahoo!’s Image Search based on a users’ tags, but I didn’t find it that useful. “Check it out”:1 if you are interested.

I put a link in the _Search_ area of the sidebar to the ZoingerPosts extisp.icio.us “text map”:5. It might be useful in navigating archived posts. I’ve also updated the Del.icio.us “static page”:4 (which I am still working on… as I am all my static pages) to include extisp.icio.us.

I’ve been thinking that Del.icio.us is a bit too “free form” — that is, it’s completely flat with no real hierarchy or structure. Yes, you can do “and” searches, but that’s not really structure (”this”:2 is an example of an “and” search). This has changed with the addition of a new “Experimental” feature called _tag bundles_.

It’s a bit hard to explain what _tag bundles_ are, so I thought I’d run you through the creation of one.

Making sure that you are logged into del.icio.us, click on the _Settings_ tab in the upper left hand corner (the _Settings_ tab will not display if you are not logged in). Under the normal settings controls, you’ll find the _Experimental_ features. Click on _tagged bundles_.

!/img/delicious_tag_bundles1.png!

From here, click the _create a new bundle_.

!/img/delicious_tag_bundles_3.png!

This is where the action is. This page is where you actually create the bundle by entering in a name for the bundle on the left (right above _submit a query_), while on the right you enter the tags you would like to bundle together. After filling out both fields, click on _submit a query_.

!/img/delicious_tag_bundles_4.png!

Here’s an example of a completed bundle that I created for the “ZoingerPosts”:4 Del.icio.us account (the Del.icio.us tagged post archive for this blog). I bundled all of my WordPress category tags together under the name _Categories_.

!/img/delicious_tag_bundles2.png!

Going back to the main Del.icio.us page under _Bookmarks_ reveals a new section in the “tags” area called _Categories_. Instant hierarchy and structure of sorts. Yippie!

Compare the above screenshot with this one which I made before creating the _Categories_ tag bundle.

The Del.icio.us user “Remy”:3 is a good one to check out for an example of someone making extensive use of this feature _*Update: 2005-04-26*_ — or check out Del.icio.us user “ubi.quito.us”:6.

I’ll be using this tagged bundles more in the future to organize things for the two Zoinger Del.icio.us accounts (i.e., “Zoinger”:5 for interesting bookmarks and “ZoingerPosts”:4 for archived posts).
