Audio Knols

Google Knol tests a cool feature that automatically converts articles to audio files, which can be played or downloaded. For now, the option is available for a small number of knols, like this one about multiple sclerosis.

"We are experimenting with Audio Playback as an option for some knols, starting with a handful of English language featured knols. If this experiment is successful, we may make Audio Playback available to more knols in additional languages, and additional features," mentions a Knol help page.


Hopefully, Google will add support for text-to-speech conversions to other services like Google Docs, Google Reader or Google Book Search.

Google Tests Image Search Ads

TechCrunch reports that Google started to experiment with displaying ads next to image search results. This isn't a surprise, since Google announced in May that it intends to test display ads.

There are different formats and positions for the ads, which combine a small image with a standard text ad. Steve Poland spotted a blended ad that looked deceivingly similar to an image result.

"The big insight of Google wasn't text ads; it was that the ads should be conducive to the format. We were doing text-based search that was all textual. Visual ads don't work in that format," explained Marissa Mayer in February, when Google started to test video ads next to web search results.


Google Image Search prepares to become more useful by adding options to find similar images, recognize faces and objects. The new features will increase the site's popularity and will attract more commercial queries that could be monetized using display ads.

No More Definition Links in Google Search?

One of the easiest ways to find definitions for words and idioms was to do a Google search and then click on the words from Google's blue bar. Google linked to dictionary.com until 2005, when it switched to the more comprehensive answers.com. Unfortunately, the feature is no longer available and users will have to find other ways to get definitions.


Here are some other ways to find definitions using Google:

1. search for [define word] and you'll get a short definition for your word, most likely from WordNet. To get other definitions from different glossaries and dictionaries, click on "web definitions for...". Example: define cup.


2. a shortcut for finding a list of definitions from the web is to use the define: operator. Just search for define:cup and you'll get a lot of definitions from a variety of source, but not all of them are authoritative.

3. subscribe to the Merriam-Webster OneBox to add a special search result with definitions.


According to Search Engine Land, Answers.com got 20-25% of its traffic from the Google definition links in 2007 and there wasn't any paid deal between Google and Answers.com. The only other important search engine that shows definition links is Yahoo, but it doesn't use a third-party service.

Update: The feature is back. Maybe it was just a technical glitch.

Google Homepage Time-lapse

You can go back and see how Google's homepage evolved in the past 10 years. The video uses cached versions of Google's homepage from Internet Archive.


Google's special site for the 10th birthday shows 17 of the most interesting homepage interfaces and Philipp Lenssen analyzes some of them. My favorite Google homepage is the one from April 1999 which only included a search box, two buttons and a link to "More Google!". If you like it, there's a slightly different version at google.com/ie_rsearch.html.

Google linked to many pages that no longer exist, but they're still available at Internet Archive:
* some credits from 1998
* press coverage from 1998-1999
* older versions of Google's logo
* Google's affiliate program
* an old Google tour
* the special Katrina page.

The Invisible GoogleUpdate.exe

Most of the recently released Google software uses live installers that download the required files from Google's servers and enable an auto-updater. Whether you want to install Chrome, Gears, Lively or Google Earth's plug-in, Google first downloads a small setup file that needs an Internet connection to obtain the software.


The most important reason why Google doesn't provide offline installers for these applications is the auto-update software, which has a separate development cycle. Instead of integrating an auto-update feature in all the applications, like in Picasa, Google Desktop or Google Toolbar, Google decided to create an independent tool that deals with keeping Google software up-to-date.

"GoogleUpdate.exe is a software component that acts as a meta-installer and auto-updater in many downloadable Google applications, including Google Chrome. It keeps your programs updated with the latest features. More importantly, GoogleUpdate allows your Google applications to be rapidly updated if security flaws are discovered," details Google.

Web applications can be easily updated and everyone gets the latest version, but desktop software needs to be updated manually or by the software itself. Google chose to automatically update most of its applications, in many cases without providing an option to disable the updates and without informing the user when a new version is installed.

GoogleUpdate automatically runs in the background when you start your computer and it connects to Google's servers every few hours to check if there are updates and to report some usage data.

"When GoogleUpdate communicates with Google servers, it sends IDs of GoogleUpdate-managed applications on your computer and general usage information for these applications. GoogleUpdate also uses its own, randomly-generated unique ID number to accurately count total users. This information includes version numbers, languages, operating system, and other install or update-related details, such as whether or not the applications have been run."

GoogleUpdate is installed as a system service, which can be disabled from the services console, but there's no transparent option to uninstall it. It also installs the GoogleOneClick plug-in for Firefox, IE, Chrome that allows Google to launch the updater directly from a web page. If you kill GoogleUpdate.exe from the task manager, a scheduled task will reopen the service when your computer is idle. Google says that the service is uninstalled a few hours after you uninstall the last application that uses it. "Google Update Service uninstalls itself when there is no Google software using it. It may take a few hours after uninstalling Google software for Google Update to uninstall."

To make things even more difficult for those who manually remove the updater, "you may find that your Google programs no longer function properly and, in many cases, you may see GoogleUpdate return automatically".

Even if the software's intentions are noble, it's unfortunate that Google doesn't inform users about the updater and it doesn't provide an option to disable GoogleUpdate or to ask before downloading updates.

Google News for Blogs

Google Blog Search's homepage has been updated and it now includes a list of popular stories, which are categorized and clustered similarly to Google News.

"Blog Search uses a set of algorithms to try to determine the most popular stories in the blogosphere. We consider factors such as a blog's title and content, as well as its popularity throughout the rest of the blogging community. Then we display groups of posts that are closely related," explains the FAQ.


It seems that Google Blog Search didn't select some authoritative blogs to be listed on the homepage and almost any blog post could be included in a Blog Search cluster. There are 11 categories: politics, US, world, business, technology, video games, science, entertainment, movies, television and sports, but they aren't equally represented.

Google shows a chart for the number of blog posts that discuss a story:


Unfortunately, Google is not able to detect spam posts, plagiarism, forums or blog comments. Google Blog Search doesn't provide yet feeds for the top stories and the search results aren't clustered.


The new Blog Search homepage is a decent alternative to the technology-focused Techmeme and to Technorati's front page. Hopefully, Google will filter the low-quality posts and it will integrate the service with Google News.

Google Time Machine: the Web in 2001

Google brought back the index from January 2001 to show how many things have changed in almost 8 years. At that time, Google's index included 1,326,920,000 web pages and it was the most comprehensive index of a search engine.

Google explains that the index from January 2001 is the earliest available. "Well, for various technical reasons that are too boring to go into, earlier versions of our index aren't readily accessible. But we did still want to offer users a chance to search an older index as a way of looking back at web history, and the January 2001 index is the best we can do."

As Wikipedia informs us, January 2001 was an important month: Wikipedia is founded, George W. Bush becomes the 43rd President of the United States and Apple introduces iTunes.


A search for Gmail returned results about a Linux mail client and the Garfield email service:


If you search for Google, you'll find references to very few Google services: Google Directory, Google Toolbar and specialized search engines for Apple, Linux, but not yet Microsoft.


In 2001, Google's algorithms were less smart than today:


Unfortunately, Google doesn't use the interface from 2001 and the exclamation mark has been removed from the logo in 1999. Here's an original Google SERP from May 2001, courtesy of Christina Wodtke:


Another anachronism is this error page titled "2001 problems":

Google Photo Search

Google Image Search has a new option that allows you to restrict the results to photos: just select "Return images that contain photo content" from the advanced search page.


A simple way to find photos would be to restrict the results to JPEG files, but a search for Gmail shows that many people use the JPEG format for logos and screenshots. If we use Google's image analysis technology, we'll find more photos related to Gmail, including the Gmail soap, Gmail Theater and Gmail's product manager Keith Coleman.

The other two content restrictions available in Google Image Search are for images that contain faces and for images that illustrate recent news articles. Microsoft's image search engine has more advanced options for refining your search: you can find photos, illustrations, faces and portraits.

Lively, a Future Platform for Online Games

"X-Ray Kid is the team that was recruited by Google to establish the visual style and aesthetic direction" for Lively, the 3D chat service launched in July. "It's been 2 years of work, dozens of original character designs, each with hundreds of unique animations, thousands of clothing variations and original sound content. In addition, we also produced numerous themed environments, hundreds of objects, animated room buddies, and the list goes on," explains the game development studio.

Kevin Hanna, creative director at X-Ray Kid, offers some insights on Lively's future in an interview for GamesIndustry.biz. Kevin says that there are lot of interesting features that will be added to Lively:

Some of my favourite stuff has yet to come out. There's a lot of different characters, and cute animals and stuff, but we didn't do anything really genre-pushing. I think with the next step we're going to be still within that style, but really pushing the different genres of known game types. (...) There is a longer term goal of opening up the API so the architecture of Lively could be used as an online games platform.

Google has already bought AdScape, a company that monetizes games by placing relevant advertising, and some speculated that Google intends to acquire Valve, the company that developed Half Life.

Google Groups Video Results

Google adjusted the interface for video results that are part of universal search. Until now, Google promoted two videos in the first 10 results if the query was strongly associated with videos, but they looked like standard results. The new interface separates the two results from Google Video and this is more in line with other types of OneBoxes (images, local business, news) that evolved into universal search results.

Another change is that the image results group has 4 images instead of only 3 and it can be displayed inside the list of search results, not just at the top or at the bottom. When the image results group shows up at the top of the page, the thumbnails are significantly larger.


Building an universal search engine that manages to rank web pages, images, videos, books, maps turned out to be a difficult task, so Google tries to do something easier: rank OneBoxes for different specialized search engines and display them in appropriate places. You can find a version of Google that doesn't include universal search results at searchmash.com.
