Securing Your Printer with IEEE P2600

Once upon a time, we didn’t even think about securing the information on our printers. Oh, certainly we didn’t want someone on the help desk printing out a Dilbert cartoon on the executive suite’s prize color laser printer, but making sure no one could read a recently printed document from the printer’s own queue? Why bother?

That was then. This is now.

Today, as Mike Howard, Worldwide Security Leader for Managed Enterprise Solutions at HP, recently said, our “printers are essentially servers and they need to be treated and protected as such.”

It’s not just printers, though. Modern office copiers and multi-function peripherals (MFP) also keep documents, names, email addresses, and fax numbers on their hard drives. That means such data has to be protected to keep your company’s data safe.

Furthermore, you may be legally obligated to make sure no hackers get into your printer or other hard copy device (HCD) storage.

The list of laws that require you to keep your HCD’s documents safe from hackers goes on and on. A short list includes the U.S. Health Insurance Portability and Accountability Act (HIPAA), Gramm-Leach-Bliley Act, Common Criteria, and Sarbanes–Oxley (SOX).

Oracle’s Google Android patent lawsuit cut down to size

Instead of extracting billions from Google for violating its Java software patents in Android, Oracle will be lucky to get over a $100-million from its intellectual property (IP) lawsuit. That’s chump change by mega-company standards. Taking into consideration the legal costs, Oracle could have made more money if it had just offered Google an open-ended Java license in the first place. Larry Ellison, Oracle’s God-King and CEO, will have to wait another year before buying the sharks with lasers on their heads to guard his mega-yacht.

Back in 2010, Oracle sued Google for Java copyright and patent violations. At the time, Oracle’s Java lawsuit was a shocking move. Oracle, a founding members of the Linux Foundation, was suing a company over Android, which is a mobile Linux distribution. As Stephen O’Grady, one of the founders of Red Monk, the developer-oriented analysis firm, said at the time, “This is simply a case of Oracle being less concerned than Sun about being perceived as a bad actor. It is interesting, however, that Oracle appears to be willing to trade short-term transactional gains for long-term ecosystem health.”

Still, the Sun insiders who were still on board as Oracle took over the company saw this coming. As James Gosling, Java’s creator, said at the time, “Oracle finally filed a patent lawsuit against Google. Not a big surprise. During the integration meetings between Sun and Oracle where we were being grilled about the patent situation between Sun and Google, we could see the Oracle lawyer’s eyes sparkle. Filing patent suits was never in Sun’s genetic code.” Suing companies, however, is in Oracle’s genes.

Android and Linux re-merge into one operating system

Android has always been Linux, but for years the Android project went its own way and its code wasn’t merged back into the main Linux tree. Now, much sooner than Linus Torvalds, Linux’s founder and lead developer, had expected, Android has officially merged back into Linux’s mainline.

The fork between Android and Linux all began in the fall of 2010, “Google engineer Patrick Brady stated that Android is not Linux” That was never actually the case. Android has always been Linux at heart.

Apple’s new iPad display is better than most HDTVs

Some people think that Apple’s new iPad Retina Display is a game-changer. Others say that, yes it is better but its “isn’t quite like the jaw-dropping jump,” they’d been led to expect. So, which is it? h Dr, Raymond Soneira, president of DisplayMate, the world’s leading display and display tuning company, has put the next-generation iPad to the test bench and found that the “The display on the new iPad decisively beats (blows away) all of the Tablets we have previously tested.

How so? Well, for starters, the new iPad really does meet Steve Jobs’ Retina Display specification. To do that, “an iPad Retina Display only needs 240 ppi (pixel per inch) – and it has 264 ppi. So according to Apple’s own definition, [which is based on 20/20 vision] the new iPad is indeed a true ‘Retina Display.’”

Amazon EC2 cloud is made up of almost half-a-million Linux servers

We know that Linux on servers is big and getting bigger. We also knew that Linux, thanks to open-source cloud programs like Eucalyptus and OpenStack, was growing fast on clouds. What he hadn’t know that Amazon’s Elastic Compute Cloud (EC2), had close to half-a-million servers already running on a Red Hat Linux variant.

Huang Liu, a Research Manager with Accenture Technology Lab with a Ph.D. in Electrical Engineering whose has done extensive work on cloud-computing, analyzed EC2’s infrastructure and found that Amazon EC2 is currently made up of 454,400 servers.

While Amazon has never officially said what it’s running as EC2’s base operating system, it’s generally accepted that it’s a customized version of Red Hat Enterprise Linux (RHEL). On top of that, for the virtual machines, Amazon uses the Xen hypervisor to host Linux; OpenSolaris; Solaris; Windows 2003 and 2008; and FreeBSD and NetBSD virtual machine instances.

Amazon also doesn’t talk about how many servers their popular cloud is made up of, so Huang had to work it out. He explained, “Figuring out EC2’s size is not trivial.

Linux servers keep growing, Windows & Unix keep shrinking

In 2011, we saw, according to IDC’s latest Worldwide Quarterly Server Tracker, factory revenue in the worldwide server market grew for Linux while it shrank for Windows and Unix. What I find especially interesting about this is that IDC doesn’t measure when you or your company install Linux on a bare-metal server or a re-purposed server, which is historically how Linux got into companies, but only servers with Linux already pre-installed.

That means more and more customers are asking IBM, HP and Dell, the big three server hardware vendors, for Linux on their hardware. Specifically, IDC found that “Linux server demand was positively impacted by high performance computing (HPC) and cloud infrastructure deployments, as hardware revenue improved 2.2% year over year in 4Q11 to $2.6 billion. Linux servers now represent 18.4% of all server revenue, up 1.7 points when compared with the fourth quarter of 2010.

Its competitors? “Windows server demand subsided slightly in 4Q11 as hardware revenue decreased 1.5% year over year. Quarterly revenue of $6.5 billion for Windows servers represented 45.8% of overall quarterly factory revenue, up 2.6 points over the prior year’s quarter.”

As has long been the case, Unix is the server operating system that really got knocked around. “Unix servers experienced a revenue decline of 10.7% year over year to $3.4 billion representing 24.2% of quarterly server revenue for the quarter. IBM grew Unix server revenue 2.5% year-over-year and gained 7.9 points of Unix server market share when compared with the fourth quarter of 2010.”
