Captcha

Captcha 12/24/2004 12:57 PM

Captcha: Those little "distorted text in a picture" thingies have a name. Who knew?

A captcha (an acronym for "completely automated public Turing test to tell computers and humans apart") is a type of challenge-response test used in computing to determine whether or not the user is human. [...]

A common type of captcha requires that the user type the letters of a distorted and/or obscured sequence of letters or digits that appears on the screen. Because the test is administered by a computer, in contrast to the standard Turing test that is administered by a human, a captcha is sometimes described as a reverse Turing test.

The captcha.php module prevents WWW bots from submitting HTML forms by presenting an image that must be identified before the submission will be accepted. It is very easy to use and integrate because of its simple API and sensible defaults. Built-in timeouts make database tracking unnecessary, and by using data: URIs it does not need any temporary files. For visually impaired users or text-only browsers, a letter riddle can be provided instead of an image.

Changes:
The double-redirection workaround was added for the outdated Microsoft Internet Explorer.

Anatomy of comment spam script vendors:
Emil Kacperski, Eugene Blagodarny and
corporate helpers 09/18/2004 07:10 AM
One of the curious things about blog comment spam is how asymmetrical it is. When I've had my site spammed, it feels like a desecration. If you have ever had your house broken into, it is a similar feeling. It is as if someone has come into your house while you were out, defecated on the floor, ransacked through all your belongings, and made off with your valuables. I have read some pretty impressive rants from people after they've been hammered, and they seem to have a similar impression. It feels like a personal affront. But it isn't. It's just a script that somebody wrote that connects to a database they have populated. Spammers never see our rants and raves about their activities. But who does write and sell these scripts? I have always been curious about what kind of scum writes and sells what must be increasingly sophisticated scripts, so when I noticed that my weblog was being hit repeatedly by a strange entry, www.php-soft.com, I wondered what it was and checked out the site. It turns out to be a vendor of comment spamming software. From the sales pitch at http://www.php-soft.com/advanced_blog_guestbook_messages_board_submitt er (not using proper hyperlinks for what I hope are obvious reasons): This is the perfect unique tool that quickly submits your information to any messages board/guestbook/blog or any other web script using the most effective technique and offers you fantastic opportunities for your web site promotion, increasing the link popularity of your web project. The most effective method of increasing the link popularity of your site is to post to online messages boards, guestbooks and blogs (e.g. LiveJournal). I am very glad that we can introduce our messages boards/blogs/guestbooks submission software to you.... We have the biggest database of discussion boards, guestbooks, blogs with high page rank. Our advanced submitter is a set of php scripts which can easily be installed on your home PC or your hosting server. This software is useful for any kind of data submission. You can fill the database with information using the following methods: manually one by one, from the list copied into textarea, from the textual file, gathering URLs using Google search engine (enter any script name [e.g. addpost.cgi] into URLs management tool and let our software add all such scripts URLs to your database with one button click), generate URLs list using special rules (regular expressions). You can use...

XHTML and the script tag

XHTML and the script tag 01/07/2004 06:49 PM
So for some odd reason, my alpha Kinja design that was visible in IE, Camino, Firebird, and Safari on IE and Mac suddenly stopped rendering on IE/Mac, IE/Windows, and Safari/Mac (didn't test the others, was too busy freaking out). I tried everything I could think of, validated the code (clean XHMTL 1.0 Strict), validated the CSS, had some friends take a look, and nothing. "View source" showed code, but nothing appeared on screen. Finally, after commenting out code line by line, I nailed it. In my header, I had:

<script src="/functions.js" type="text/javascript" />

While the validator liked this, and Camino had no problem, the other browers barfed big time and treated it as an unclosed tag, rendering nothing more. A quick change to:

<script src="/functions.js" type="text/javascript"></script>

and all is right with the world again. I write this because I'm sure I'll have this problem again, and then Google will help me (hi idiot Meg from the future making the same mistakes again!) In the meantime, it may help you.

iDo Script Scheduler 1.5.1

iDo Script Scheduler 1.5.1 03/14/2003 03:45 PM
iDo Script Scheduler lets you create a schedule to run your scripts and it can also be controlled by AppleScript. Not only can you automatically launch your scripts, but each time they run, you can pass a line of parameters to your script.

Release notes: Background software updated to match PowerKey 4.1.4. Added an "Execute Event" item to the Edit menu to run a script immediately. Added a contextual menu to create, edit and delete events. In some circumstances, if iDo Script Scheduler was used in conjunction with the PowerKey 4.1.3 software, the scheduled scripts failed to run -- fixed. In Mac OS 9, hot key events were affected by the state of the caps lock key, even though it was not displayed in the event editor -- fixed. (In OS X, the caps lock key is ignored when creating or activating hot keys.)
