Their premier product has had its own share of exploits over the years, which are not necessarily the same as the vulnerabilities that Adobe's Acrobat Reader has faced. Computerworld Magazine's security blog reports that the current FoxIt Reader vulnerabilities are different here:

The Foxit and Adobe bugs are unrelated, however, except for the fact that they are both in the code that parses JBIG2 images, said Thomas Kristensen, chief technology officer at Secunia, the Danish company that reported the flaw to Foxit. "It is a completely different vulnerability related to JBIG2," Kristensen said in an e-mail today.

FoxIt Reader has an integrated update system, so current users should be able to get the latest update automatically, or via the Check For Updates Now link in the Help pull-down menu. The patch details are also available from FoxIt directly.

Originally designed as a solution for e-commerce sites, the service strangely called Adam is not complicated to use. However, the company does estimate that the time it takes from mashup creation to having it live on your web site could be approximately 20 minutes. That's a little bit longer than just linking to a PDF or even uploading it to a document-hosting service like Scridb or Issuu. Still, the extra time may be worth it because Adam lets you create a truly interactive document by allowing you to add videos, HTML, stylized text, and more to what were previously just plain files.

For those familiar with designing web pages, the process may seem familiar. To add content to a document on Adam, you select various "hotspots" in the document and then add the content you want to mashup. This is where you would paste in any text, images, music, or videos you want to appear when the user mouses over that part of the document. The service currently integrates with other content providers including YouTube, flickr, metacafe, Veoh, vimeo, and imeem.

The best way to understand what Adam can do, though, is to view some sample of it in action. You can check out a mashed up floor plan or you can see all the content providers in use on one document.

Adam doesn't provide anything that a talented web designer can't already do on their own, but like every service that comes out of the Web 2.0 movement, it's about letting everyone have access to the tools that previously only skilled professionals knew how to use. If you want to try Adam for yourself, you can sign up here.

Kelly is using the PDF Ads for True Films 3.0. Kelly calls the use of the ads an experiment. "If it works with you readers to the same degree that ad-supported blogs have, it is not hard to imagine thousands of books being released for free with ads on the side," writes Kelly on his blog. "To some in publishing this prospect is the end of the world. The final stake in the heart of good old books. Ads-in-books specifically have been a bogeyman too horrible for them to even think about. [...] I am more pragmatic. I actually like the Google contextual ads on Cool Tools. They bring up choices I would have never encountered, yet they are fairly unobtrusive until you are looking. Why not do the same for books?"

But there are a couple of major obstacles to PDF Ads that I see in this initial iteration. The first is that the ads are opt-in. Because Acrobat Reader needs to connect to Adobe to download the ad content, it first asks for permission (the PDF files are scanned by Yahoo!'s content matching system before you download them, so the Yahoo! robot isn't actually scanning a file on your computer, but it will try to connect to Adobe each time you open to the file to attempt to download the most up-to-date ads). Will people really opt-in to view ads? Hardcore supporters of the author might, but since they're paid on a per click basis, if the people clicking on the ads are only doing so out of support for the author, isn't the advertiser losing out? That's not going to likely be high quality traffic.

The other major hurdle is that the content matching sucks. While reading True Film 3.0, I didn't see one ad that had anything to do with film or documentaries or even the subjects that any of the documentaries being reviewed were about. Instead, the ads were about unrelated things like travel and real estate -- they looks more like broadly purchased defaults (low paying inventory filling ads) than actual contextually matched advertisements. In order for PDF ads to warrant any notice from readers, they'll have to get a lot more relevant.
