Google's new search index, Caffeine, finally arrives

Almost a year ago, we told you about Google's experiments to improve the speed and relevance of its searches with a new index code named Caffeine. I had forgotten all about that until this week, when Google's official blog revealed that Caffeine is finally here. Google says searches will be 50% faster now, and that Caffeine means Google's index is closer than ever to keeping pace with the live Web.

Caffeine basically checks the Web for new content in smaller chunks than the old index, and it does so more frequently, meaning new content gets added to Google much more quickly. Caffeine is also more flexible than the old method of indexing, so Google can update to keep pace with new developments on the Web. Don't you just feel faster already? Wheeee!

How To Hide Text In Microsoft Word 2007, Reveal It & Protect It

Sometimes what we hide is more important than what we reveal. Especially, documents with sensitive information, some things are supposed to be ‘for some eyes only’. Such scenarios are quite common, even for the more un-secretive among us. You want to show someone a letter composed in MS Word, but want to keep some of the content private; or it’s an official letter with some part of it having critical data. As important as these two are, the most common use could involve a normal printing job. Many a time we have to print different versions of a document, one copy for one set of eyes and others for other sets. Rather than creating multiple copies and therefore multiple printing jobs, what if we could just do it from the same document? That too, without the hassle of repeated cut and paste. We can, with a simple feature in MS Word – it’s just called Hidden and let me show you how to use it to hide text in Microsoft Word 2007. It’s a simple single click process. Open the document

Ex-Skypers Launch Virtual Whiteboard Deekit

Although seriously long in the tooth and being disrupted by a plethora of startups, for many years Skype has existed as an almost ubiquitous app in any remote team’s toolkit. So it seems apt that a new startup founded by a team of ex-Skype employees is set to tackle another aspect of online collaboration. Deekit, which exits private beta today, is a virtual and collaborative whiteboard to help remote teams work smarter. The Tallinn, Estonia-based startup is headed up by founder and CEO, Kaili Kleemeier, who was previously a Head of Operations at Skype. She and three colleagues quit the Internet calling giant in 2012 and spent a year researching ideas in the remote team space. They ended up focusing on creating a new virtual whiteboard, born out of Kleemeier’s experience collaborating with technical teams remotely, specifically helping Skype deal with incident management. “Working with remote teams has been a challenge in many ways – cultural differences, language differences, a

Zoom buys cloud call center firm Five9 for $14.7 billion

Zoom is taking advantage of the impressive rise in its stock price in the past year to make its first major acquisition. The popular video conferencing firm, which was valued at about $9 billion at its IPO two years ago, said Sunday evening it has agreed a deal to buy cloud call centre service provider Five9 for about $14.7 billion in an all-stock transaction. 20-year-old Five9 will become an operating unit of Zoom after the deal, which is expected to close in the first half of 2022, the two firms said. The proposed acquisition is Zoom’s latest attempt to expand its offerings. In the past year, the video conferencing software has added several office collaboration products, a cloud phone system, and an all-in-one home communications appliance. The acquisition of Five9 — which has amassed over 2,000 customers worldwide including Citrix and Under Armour and processes over 7 billion minutes of calls annually — will help Zoom enter the “$24 billion” market for contact centers, the comp
