Four knowns and four unknowns in Google’s Alphabet soup

When Google announced on Monday that it would create a new holding company called Alphabet, of which Google Inc. will be just one part, Larry Page said the new structure would allow the company to get more ambitious things done. But there was still a lot that he didn’t say.The move should free up time for Page and Sergey Brin to focus on Google’s forward looking projects like self-driving cars, and allow other leaders, like Sundar Pichai, to take care of the core businesses. It should also provide a bit more transparency for Google’s investors, allowing them to see better how those core businesses are performing.But there are questions too, about how Alphabet will evolve and which other companies might get their own CEOs. Here are four knowns and unknowns about what happened yesterday.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Using Cisco VIRL for ASA Emulation

In this post, I will demonstrate the power of Cisco VIRL when it comes to an emulation of the Cisco Adaptive Security Appliance. In future posts, I will demonstrate other images that are available.  This post was created using the latest VIRL version and ASA image available at the time of this writing. That is VIRL 0.10.14.20 and the ASA 9.4.1-200 code. Be sure to check the specific codes available as you read this, since VIRL is consistently updated as are the images it runs.  To get started, I create a new blank topology in VIRL:  I then select and place the objects I need and connect them in the topology:To read this article in full or to leave a comment, please click here

Internet giants to block child porn images using a common list

Facebook, Google, Twitter, Yahoo and Microsoft will take a new step toward combating the spread of child pornography, by blocking images identified in partnership with an industry group.The companies will block images of child sexual abuse that have been identified by the Internet Watch Foundation, a U.K.-based nonprofit that aims to locate and stamp out such content online. The effort is aimed at speeding up the identification and removal of images of child sexual abuse worldwide, and preventing them from being uploaded in the first place.Only known child sexual abuse images identified by the IWF will be blocked. Each company will download a list of images that have been “hashed” by IWF analysts, under a process that creates a digital fingerprint of each image. The hashes are created from images that IWF’s analysts have assessed, which come from various online sources like reports from the public, and the U.K.’s Child Abuse Image Database.To read this article in full or to leave a comment, please click here

Cofounders Sergey Brin and Larry Page are now president and CEO of the Alphabet holding company, respectively, while Sundar Pichai, formerly a vice president in charge of Android, Chrome and Google apps, will become Google’s CEO.To read this article in full or to leave a comment, please click here
