Microsoft (Nasdaq:MSFT) and Apple (Nasdaq:APPL) are goliaths, two of the largest companies on the planet. Microsoft is a $270 billion company, while Apple is valued at a slightly lower $225 billion, based on their current stock prices. Yet just a decade ago, the thought that Apple's worth could be in even the same ballpark as Microsoft would have been ludicrous. The gap has closed, thanks to an amazing resurgence of Apple over the past 10 years. To say that Apple was teetering over the cliff before catching itself is not hyperbole.

Hackers exploit Adobe vulnerability
Hackers have been attempting to exploit an unpatched hole in Adobe Reader's PDF document format using a variant of the infamous Zeus bot.
It comes in the form of a malicious PDF file that embeds the attack code in the document.
"When this PDF is opened In Adobe Reader with JavaScript enabled, the exportDataOject function causes a dialog box to be displayed asking the user to 'specify a file to extract to'," says Gavin Neale of M86 Security.
"The default file is the name of the attachment, Royal_Mail_Delivery_Notice.pdf. This could be somewhat confusing to users, and not really knowing what is happening, they may just click save (It appears as if they are just saving a PDF file after all). Users of Foxit PDF reader will get no warning and the attachment will be saved to the users Documents folder." more......

Meet the Cisco Nexus 1010, a switch
One of the products that generated a fair number of questions with last week’s announcement was our Nexus 1010. Since I got a number of very similar questions, let me answer them all here at once.
So, lets start with a quick recap. The Nexus 1000 switch architecture is modeled after a modular switch such as our Catalyst 6500 or Nexus 7000—the N1K series does, in fact, run NX-OS like the rest of the Cisco Nexus and Cisco MDS families. Like a modular switch, we have virtualized line cards we call Virtual Ethernet Modules (VEM) which is the software that replaces the vSwitch in a vSphere host. We also have virtualized supervisor modules calledm strangely enough, Virtual Supervisor Modules that provide management and control plane functions (they don’t get involved in packet forwarding). Prior to the Nexus 1010, the VSM software has run as a virtual appliance on a handy server in the data center. more....

Can Facebook or Twitter Spin Off the Next Hadoop?
Like most people, I suspect, I wasn’t too surprised to find out that Hadoop-focused startup Karmasphere has secured a $5 million initial funding round. After all, if Hadoop catches on like the evidence suggests it will, Karmasphere’s desktop-based Hadoop-management tools could pay off investors many times over. In some ways, though, the fact that Hadoop is mature enough to inspire commercial products means it’s yesterday’s news. Now, I’m wondering, which open-source, big-data-inspired product will be the next to launch a wave of startups and drive tens of millions in VC spending? more........
