Smarter Image Hotlinking Prevention 07/13/2004 01:32 PM

Most web professionals are all too aware of the problems caused by hotlinkers. Leechers. Bandwidth thieves. People who use images hosted on your web server on their own pages. With PHP and mod_rewrite, you can disallow embedding and allow linking while automatically creating gallery pages for those direct linkers.

If you run a site heavy on images (or even just a popular site that people might grab the images from), you're all too familiar with the practice of "hotlinking" - the linking to of your images from other sites. Well, if you think there's not much you can do about it - you're wrong, and this new article from A List Apart proves it.

Prevention – Bah! Humbug!


Prevention – Bah! Humbug! 12/19/2004 03:17 PM
Prevention gets short-changed when a health care system is under strain according to members of The Science Advisory Board. In a recent Instant Poll sponsored by the Board, 50% of the 1,100+ respondents believe that when medical care is constrained by limited resources, disease prevention and health promotion efforts suffer. An additional 25% of those polled think that adequate treatments and therapies are in jeopardy if funding is at risk. In contrast, participants believe that follow-up services and diagnosis receive the most attention regardless of resource limitations. [PRWEB Dec 2, 2004]

Smarter Than Me


Smarter Than Me 12/29/2003 11:44 PM
Sometimes I'm accused of being "smart," which bothers me since I don't know what it means. It's a comparative label: if this one is smart, then others are equally smart, smarter, or less smart. Yet all generalizations are false, all comparisons fail. There's no way to measure these things, not really. It's a bogus idea. That's not exactly right. I quickly identify folks smarter than me, but it's not empirical, just a cocktail party chat I have with myself. Probably...

Tinderbox Keeps Getting Smarter


Tinderbox Keeps Getting Smarter 03/22/2005 04:58 PM
Matt Neuburg (~210 words)

Tinderbox Keeps Getting Smarter -- Eastgate Systems' Tinderbox has been upgraded to version 2.4. Tinderbox (see my review in TidBITS-651) is a superb way to create heavily hyperlinked text; text snippets are stored in a hierarchical structure and can be exported as Web pages. I used Tinderbox to create the online help for the Perl editor Affrus, which blogger John Gruber has called "the finest software documentation," in part because it is "cross-linked out the ying-yang." Tinderbox 2.4 makes outlines smarter by permitting any entry to have a rule for updating itself periodically; for example, if you're using Tinderbox to maintain a to-do list, a parent item (representing a category or group of tasks) might have a rule that its "completed" attribute should be true if and only if the "completed" attribute of all its children (the actual tasks) is true. There are also many small bug fixes and aesthetic tweaks, and Tinderbox's Web-page export continues to evolve strongly. Tinderbox runs in both the classic Mac OS (Mac OS 9.2 recommended) and Mac OS X 10.0 and later. Tinderbox costs $165, plus $70 annually for free updates. A demo version is available for download.

spambots get smarter


spambots get smarter 01/06/2004 01:03 PM

Since today started as a "spam kind of day"...

Something I noticed over the last few weeks is that I've started to receive spam that is way more targeted than before. In what sense?

Well, let's say this: I'm getting spam that not only knows my full name, but also my address. Okay, not my current address, but I've already gotten spam that explictly mentions both my New York address (from 5+ years ago) and my SF Bay address (from 2+ years ago). This is bad, not only they know my email address, but they also know where I live(d)! Yes, we know that with time and money you can get a lot of information on anyone, but this has to be done automatically and massively, or otherwise it wouldn't be a practical option for spammers.

Clearly, one way this could happen is if someone (say, buy.com) has been selling their customer information. Since I usually take care of buying online only when my privacy is more or less protected, this is unlikely, though certainly possible.

There's a more likely way in which this connection was made: Google.

Google not only knows the web, it also knows other information... like phone numbers (at least in the US). Jon mentioned this some time ago.

A spambot to get "connected information" would work like this. Say you write an automated script to go through phone numbers on Google. Then the script takes the address data and the person's name, and then googles the person's name. It takes the first few results (or maybe only the first one) and scans the resulting pages to match an email's name to the person's name. Sure, this won't be 100% correct, but spammers don't care about that. And Google's reach makes it reasonable to think that you'd have a reasonably high hit rate. You could even write a program that uses the GoogleAPI for it.

Sure, we could say, as Scott McNealy does, that "you're privacy is gone, get over it". Even if you don't agree with that statement (and I don't, at least I want to resist it!), this is nevertheless disturbing. And the question that follows is: does Google have any responsibility for this? They'd probably say that they're providing a service by integrating yellow pages information, which would be true.

I'm not picking on Google, rather Google is the example here because of its reach and pervasiveness, but I'm sure that similar things can be done with other search engines and if not it won't be long before you can. Can we fix this at all? If so, how?

Since this is the tip of the iceberg, my main thought at the moment is that I'm a character from Lost in Space and all I hear is "Danger Will Robinson! Danger!".


Comment Spam Prevention Goes Nuclear


Comment Spam Prevention Goes Nuclear 12/28/2004 01:10 PM

Elliot Back has come up with the best anti-comment-spam measure I've heard in quite a while.

Taking Matt's stopgap spam solution, which sends precomputed hashes to be echoed back by the user-agent's form, I've added dynamic generation of the md5 hash. Rather than write it to a hidden field, we wait until the form is submitted to compute the hash. This prevents spammers from automatically scraping the form, because anyone wanting to submit a comment must execute the javascript md5.

Here, as I understand it, is the method:

  • Before the form is generated, the server creates a short MD5 hash and includes it in the comment form. It also includes an MD5 hash javascript function in the page.
  • When the user submits the comment form, the original MD5 hash is re-hashed by the browser using the js function, resulting in a new hash. The new hash is included in the post to the server.
  • The server makes sure that the new hash is a proper result of hashing the original hash.

This ensures that the browser end must have executed the javascript code. Pretty slick. Of course, if everyone uses it, comment spam tools will be quickly rewritten to be able to handle MD5 hashing, but until then we could enjoy a little spam-free blogging. Well done.
