RadiUID: Palo Alto User-ID and RADIUS

The Palo Alto User-ID feature is awesome as long as you can feed it IP-to-User mappings. PAN provides agents to do this which work in many environments, but not usually without Active Directory. I wrote RadiUID to perform this function in situations where all you have is RADIUS. Approx Reading Time: 5-15 Minutes You see, […]

IBM’s latest move may have cracked the code on a cheaper DRAM alternative

A cheaper alternative to DRAM just took a step closer to enterprise data centers as IBM unveiled a way to make it more dense.PCM (phase-change memory) is one of a handful of emerging technologies that aim to be faster than flash and less expensive than DRAM. They could give enterprises and consumers faster access to data at lower cost, but there are challenges to overcome before that happens.Density is one of those, and IBM says it’s achieved a new high in that area with a version of PCM that can fit three bits on each cell. That’s 50 percent more than the company showed off in 2011 with a two-bit form of PCM. Greater density lets IBM squeeze more capacity out of what is still a pricey technology.To read this article in full or to leave a comment, please click here

Enable nested virtualization on supported hardware. (Fixing WARNING KVM acceleration not available, using ‘qemu’ issue)

Source: http://samadhisoft.com/wp-content/uploads/2009/05/nested-boxes.jpg     
Whats fun without pushing things to the limit, making them do things that they weren't designed for and creating something cool. If the end result isn't cool that's ok too. My take here is that giving something a try not only keeps you occupied  but also contributes to gaining knowledge. Insights acquired in this process of pushing boundaries is definitely worth all the effort. Nested Virtualization once was a cool thing and is still is for a lot of people out there. If you are on a modern x86 (Intel) architecture processor backed computer, it most probably will support nested virtualization.

For beginners out there, nested virtualization is nothing but the process of allowing a virtual medium such as a virtual machine or a container to be able to not only act as physical hardware but also further create another abstraction within itself. Think about it as a smaller container/box within a larger box. Although you can perceive the smaller box as the only box when seen from within, it isn't so. Now put a smaller box within it - that's nested virtualization. Each level of nesting does make it tighter Continue reading

Five questions for Google to answer at its big I/O conference

Google’s I/O developer conference starts Wednesday and some big announcements are expected during the opening two-hour keynote, likely around virtual reality, Android and the Internet of Things.In a change of pace, the show is being held outdoors at the Shoreline Amphitheater in Mountain View, California, and Google has advised the press to pack sunscreen along with laptops and mobile devices. Here are five questions I want company executives to answer during the course of this year's keynote. What’s the company’s plan for the Internet of Things? Google has made some big bets on the Internet of Things, with its Brillo and Weave developer tools, along with its acquisition of Nest in 2014. Then, there’s the OnHub wireless router Google announced last year. It’s clear that the company is interested in playing a major role as part of the growing world of internet-connected devices, but it’s been a while since we’ve heard anything major from the company in the IoT realm.To read this article in full or to leave a comment, please click here

Label Switched Multicast — Q&A

This post is the last one I'm planning in this series on Label Switched Multicast (LSM). The questions & answers below are meant to expand on topics from the previous posts or address topics that weren't mentioned in the previous posts at all.

If you're not familiar with LSM yet then this Q&A likely won't make much sense to you and I recommend you go back and read through the previous posts.

A new app from SAP helps line managers keep track of their budgets

It's not often easy for line-of-business managers to get a real-time view of their budgets and spending, but a new app from SAP aims to change that.Based on SAP's Hana Cloud Platform, the app pulls data from core financial reporting systems and makes it searchable, so that line managers can do ad hoc spend analyses and other on-the-fly calculations.Called SAP RealSpend, the app lets managers drill down and perform a fine-grained analysis of actual and future spending. It can also deliver related forecast and budget plans.To read this article in full or to leave a comment, please click here

First Burst Buffer Use at Scale Bolsters Application Performance

Over the last year, we have focused on the role burst buffer technology might play in bolstering the I/O capabilities on some of the world’s largest machines and have focused on use cases ranging from the initial target to more application-centric goals.

As we have described in discussions with the initial creator of the concept, Los Alamos National Lab’s, Gary Grider, the starting point for the technology was for moving the checkpoint and restart capabilities forward faster (detailed description of how this works here). However, as the concept developed over the years, some large supercomputing sites, including the National …

Nearly all App Store sales come from a handful of vendors

The top 1 percent of U.S. publishers on the iOS App Store with paid or in-app purchase (IAP)-supported apps accounted for approximately 94 percent of all revenue on the store.That’s according to Sensor Tower, a vendor of App Store marketing and sales tracking software, which published its latest findings in its Store Intelligence blog. The company monitored app store revenue and download estimates from Jan. 1, 2016, to March 31, 2016. It compared the estimated net revenue of publishers on the U.S. App Store with at least one actively ranking paid or IAP-supported app. It does not include Google Play or Android.To read this article in full or to leave a comment, please click here

Microsoft makes final, aggressive Windows 10 upgrade push

Microsoft has launched the final push in its nine-and-a-half-month upgrade offensive against consumers and businesses running Windows 7 and Windows 8.1.Last week, Microsoft switched the automatically-offered Windows 10 upgrade to a "Recommended" download that in turn scheduled the upgrade process unless the user interfered."As we shared in October, Windows 10 will be offered as a 'Recommended' update for Windows 7 and 8.1 customers whose Windows Update settings are configured to accept 'Recommended' updates," a Microsoft spokesman said Friday in an email reply to questions.INSIDER Review: Enterprise guide to Windows 10 Those questions were spurred by reports from Computerworld readers, who said that they'd again been offered an upgrade after months of either ignoring the campaign or dodging the transmutation of their PCs from Windows 7 or 8.1 to 10.To read this article in full or to leave a comment, please click here
