Do Good CAPTCHAs Really Have To Be Unfriendly? An Expert Explains

For those of you who are not familiar with the term, a CAPTCHA is a feature on many user populated websites, such as Myspace with the purpose of blocking automated programs from spamming its users and for overall security. Here is how it works:

A user is required to enter a random letter and number password into a form before being able to submit information, log in, etc. This password is essentially given directly to the user in an image, rather than in text form, so that an automated program cannot detect the characters. The password the form field expects is the same as that shown on the image, but this sometimes causes problems.

Jeff Atwood at the Coding Horrors blog discusses whether CAPTCHAs are dead. This follows a news report that scalpers probably beat the CAPTCHAs at Ticketmaster.

Jeff links to a Chinese site that sells CAPTCHA decoders. The site quotes different prices for breaking different CAPTCHAs. An eBay decoder, for example, is being sold for $4000 and claims 70% accuracy.

What caught my attention were the unbreakable CAPTCHAs in the list. The Yahoo CAPTCHA is listed as unbreakable. That isn't surprising. Most of us can barely get it right ourselves.

Consider a Yahoo CAPTCHA. Sometimes you cannot tell the difference between a G or a 6? And the way that letters are often skewed, the difference bewteen certain uppercase and lowercase letters is virtually unrecognizable?

Contrast that with a Google CAPTCHA also listed as unbreakable. The Google image is clean and legible. Most of us have no difficulty getting it right. Google demonstrates that effective CAPTCHAs don't have to be unfriendly to users.

I am curious to learn which CAPTCHA libraries generate strong, yet user friendly challenges.

Reasons Why Firefox Mozilla Outweighs the Other Web Browsers

Firefox was launched as the battling sword of Mozilla against the various web browsers and more specifically Internet Explorer by Microsoft. Internet Explorer of Microsoft enjoyed the monopoly in the browser market for many years until Firefox was launched, and now Internet Explorer has to even share a major chunk of its market value with Firefox. So what makes Firefox unanimously acceptable over internet explorer or any other web browser?

Firstly it allows tabbed browsing. This is of tremendous help to someone who wants to exploit every minute of using the internet and it is also much neater and easier to view 10 tabs in a single window instead of viewing 10 different windows! Firefox works equally efficiently on different operating systems like Windows, UNIX, Linux and BSD. Another added feature in Firefox is that it has a built-in download manager. With this feature you can pause, resume or stop a downloading process as and when you like.

Firefox also provides extensive page-control. You can block ads, pop-ups, images, etc. you can also toggle with the font type and color of the websites. Firefox also provides a unique search bar with which you can search on a minimum of 10 different search engines just with the click of a button. This browser also aids in spell-check which is vital for blogging and supports online form filling; this feature is absent in internet explorer.

Apart from all this, the most satisfying and convincing benefit is that Firefox provides security on net like no other web browser. Microsoft Internet Explorer has been exploited number of times by various security threats like Spyware or any other perilous installations. Mozilla Firefox blocks such installations and is less susceptible to security breaches. The reason for this is that Firefox uses a completely different technique for security. It does not depend on any security zones or digital signatures, etc. It also does not have the ActiveX component which is used by many websites to automatically install malicious content on you computer by executing some destructive scripts.

Firefox is a completely open source project. Therefore coders can manipulate the code to add new extensions, plug-ins, bug fixers, or any other noted feature to suit the client requirements. You can even customize your Firefox browser by using the various available themes.

Thus for intense security on the net and for all of the above mentioned features, Mozilla Firefox certainly overshadows any other existing web browsers.

How to Get Number 1 Rankings on Google, Yahoo and MSN Using Video Hosting Sites

The other day, I did a test to see how fast my videos would be found in the search engines and to see how well they would rank for the keywords I was optimizing my videos for.

The results were outstanding and should bring hope to anyone who feels that getting a #1 or top 10 listing on the major search engines is out of reach. Everyone can get top listings, with videos

The process was very simple. I filmed a video, submitted and tagged my video, and 13 hours later, I was in the #1 spot. Then, 24 hours later that same video on different video networks occupied spots 1, 2 and 3 on Google.

So, how easy is it to do? Very easy, just follow these steps and you'll be getting #1 listings on Google, MSN and Yahoo in no time flat.

First - Create your video. Use a video camera or digital video camera and get the digital file on to you computer so you can manipulate it in a video editing program. If you don't have a video camera, no problem, all you need is a microphone and an audio recording program like Audacity, and you can create an mp3 audio file with 30 seconds to 5 minutes of audio, and convert that audio to video. Don't worry, that's easy too, I'll tell you how in the next steps.

Second - Edit the video file to have the look, feel, URL's and production values you like. If you made an audio file, put that audio file into the video editing software. Most PC's come with Windows Movie Maker, which is free, and you can drop the Mp3 audio in there and place, random Digital pictures throughout the length of the audio file to create the "video" images that go along with your audio.

Third - Upload the finished video file, which should be in wmv format to a video submission host, called Tubemogul. At Tubemogul, you can upload unlimited videos, and then have those videos uploaded automatically to some of the more popular video hosting sites on the internet like Youtube, Google Video, Yahoo Video, Metacafe, Revver, and some other popular one.

Let me say that Tubemogul is also MORE than just a video posting service, they are MUCH more. They can track all the video views you get DAILY on EACH video hosting site. They'll provide charts and other track meta data, that is very important to marketers to daily track stats across all the video sites. And remember, it's all free to do this.

Fourth & Final Step - Push your videos out to the video hosting sites and let Tubemogul do the work for you. But a key element is, you want people to find your videos. The search engines find videos, not based on the content said inside them, but by the tags and descriptions about them. Tagging is the single most important element of getting traffic to other websites, based on what your video is tagged for.
