Google Docs API now provides OCR service

Google API OCR DemoIf you're not a developer, you're probably not aware that Google Docs has an API available for various document-related services. Recently Google added a new feature that allows developers to create applications that will pass an image-based (.png, .jpg, or .gif) document to the API, and using OCR (Optical Character Recognition) technology, generate and pass back an editable text-based document. Currently the service can handle documents up to 10 MB in size.

For non-developers, this is certainly interesting, but not terribly useful. Well, a live demo is available that will allow you to test the service yourself. At the time of this writing I was successfully able to convert a single page document, though there are reports that the service has become overloaded and is slow or sometimes fails to respond. Given that this is a demo, that's probably not terribly surprising.

If Google is exposing this functionality to developers, it seems at least possible that it could become a built-in feature of Google Docs for regular users at some point in the near future. With Google's recent acquisition of reCaptcha, it seems likely that Google's document-scanning capabilities will soon be better than anyone else's. That would make for an incredibly powerful feature for Google to offer its users.

Google buys reCAPTCHA to improve book-scanning technology

reCAPTCHA
You know those tests that you have to fill out when signing up for new web services? The ones that ask you to enter the text you see in a box to prove that you're human? Those are called CAPTCHAs. And a company called reCAPTCHA does something really interesting with them.

It finds hard-to-read text scanned from old newspapers and books. Because the ink and paper isn't in such good shape, spambots have a hard time reading the words, but people usually don't have too much trouble. And when you're entering a word in the box, you're actually helping reCAPTCHA's software to get better at reading these old texts.

Now if your'e starting to see why a company like Google, which has been scanning old and new books like mad over the last few years, might be interested in reCAPTCHA, you're not alone. Google announced today that it's acquiring the company. Web sites that use reCAPTCHA to protect themselves and their users from spam and fraud will continue to be able to use the service, because honestly, reCAPTCHA wouldn't be as useful to Google if the company were to shut off that part of the service.

reCAPTCHA Mailhide: Make spammers work hard for your email address

reCAPTCHA Mailhide
Looking for a way to post your email address online, but don't relish the idea of spambots picking up your address and sending you email ads for Viagra and anatomical enhancement pills? ReCAPTCHA Mailhide provides a simple tool for obscuring your email address.

All you have to do is enter your email address (and hope that the folks behind Mailhide aren't doing anything nefarious with it), and reCAPTCHA Mailhide will spit out a URL and some HTML code. Both take you to a page where you have to solve a CAPTCHA test like the one shown above to reveal an email address.

You can either provide a hyperlink to the URL, or embed the HTML code in your page. If you go the HTML route, visitors to your website will see a partial email address that looks something like b...@downloadsquad.com. When they click on the "..." a window will pop up asking them to solve the CAPTCHA. In other words, people don't have to leave your web site to get your email address. They just have to be able to decipher hard-to-read text.

WordPress spam filter plugin adds captcha to Akismet

Simple Spam FilterIf you've had a blog for any length of time, you've probably been assaulted with blog comment spam. Users of WordPress have the fantastic Akismet spam filtering tool freely available to them by Automattic, the makers of WordPress. But while Akismet is good (really good), it's not perfect.

If you have been using Akismet, but are still seeing too many spam messages slipping through, consider installing Simple Spam Filter by TanTanNoodles. Simple Spam Filter has existed for a little while now as a basic spam filter, but was recently updated to make use of captcha security via reCAPTCHA. The implementation is beautiful.

Let's be honest, nobody likes having to fill out captcha forms. And you wouldn't want all of your site visitors to be facing a captcha form every time they submit a comment. Luckily, they won't. Simple Spam Filter will only offer up a captcha field to commenters whose comments are flagged as spam by the plugin itself, or by Akismet.

While it's never going to be possible to have 100% protection from comment spam, the combination of Akismet and Simple Spam Filter sure comes close, at least for now. If you've got this problem, maybe the solution is as simple as installing and enabling this WordPress plugin.

The World's Hardest Game 2.0 - Time Waster

So, just how good at time waster games are you? Think you've got the stuff? Well, The World's Hardest Game 2.0 doesn't think you do. Yes, amazingly, it's possible to have a sequel to a game called "The World's Hardest Game". It doesn't seem logically possible, since if the first one was actually the world's hardest, how could another one come along and share the moniker? It made me doubt the name in the first place. That is, until I tried the game. The mechanics of the game are very simple. You are a small red square, ...
