    • Andrew Roberts: [On Napoleon] No aspect of his command was too small to escape notice.
    • Jason Calacanis: The world has trillions of dollars sitting in bonds, cash, stocks, and real estate, which is all really “dead money.” It sits there and grows slowly and safely, taking no risk and not changing the world at all. Wouldn’t it be more interesting if we put that money to work on crazy experiments like the next Tesla, Google, Uber, Cafe X, or SpaceX?

Streamline the PCI Assessment Process with a Playbook

Why Create a PCI Assessment Playbook

Having gone through the Payment Card Industry Data Security Standard (PCI DSS) yearly assessment process several times, I can confirm it is a fairly intensive assessment that will require a large effort from a lot people!

Each assessment the Assessors will request evidence, review documentation, ask for sample system configurations, be onsite to interview and observe personnel, and present observations or findings that must be remediated. These various assessment activities and last-minute remediation efforts can be very disruptive to all involved, and usually result in “fire drill” activities that require personnel to be pulled away from their daily tasks to react to the assessment requests.

Since the PCI assessment is very similar from year to year, and with some well thought out planning it is possible to streamline the assessment process. Just like in football, having a well thought out strategy in the form of a playbook can assist everyone that needs to know their part, or what needs to be done when. With this cylinder process in place and in the form of a PCI Assessment Playbook that everyone can follow, it can greatly reduce the stress historically associated with the assessment and attaining Continue reading

Worth Reading: Google rewires the Internet

When all of your business is driven by end users coming to use your applications over the Internet, the network is arguably the most critical part of the infrastructure. That is why search engine and ad serving giant Google, which has expanded out to media serving, hosted enterprise applications, and cloud computing, has put a tremendous amount of investment into creating its own network stack. —Timothy Prickett Morgan @ The Next Platform

oVirt Webadmin GWT Debug Quick Refresh

As a developer, one drawback of using Google Web Toolkit (GWT) for the oVirt Administration Portal (aka webadmin) is that the GWT compile process takes an exceptionally long time. If you make a change in some code and rebuild the ovirt-engine project using make install-dev ..., you'll be waiting several minutes to test your change. In practice, such a long delay in the usual code-compile-refresh-test cycle would be unbearable.

Luckily, we can use GWT Super Dev Mode ("SDM") to start up a quick refresh-capable instance of the application. With SDM running, you can make a change in GWT and test the refreshed change within seconds.

If you want to step through code and use the Chrome debugger, oVirt and SDM don't work well together for debugging due to the oVirt Administration Portal's code and source map size. Therefore, below we demonstrate how to disable source maps.

Demo (40 seconds)

Steps

  1. Open a terminal, build the engine normally, and start it.

    ``` make clean install-dev PREFIX=$HOME/ovirt-engine DEV_EXTRA_BUILD_FLAGS_GWT_DEFAULTS="-Dgwt.cssResourceStyle=pretty -Dgwt.userAgent=safari" BUILD_UT=0 DEV_EXTRA_BUILD_FLAGS="-Dgwt.compiler.localWorkers=1"

    …

    $HOME/ovirt-engine/share/ovirt-engine/services/ovirt-engine/ovirt-engine.py start

    ```

  2. In a second terminal, run:

    Chrome:

    make gwt-debug DEV_BUILD_GWT_SUPER_DEV_MODE=1 DEV_EXTRA_BUILD_FLAGS_GWT_DEFAULTS="-Dgwt.userAgent=safari"

    or

    Firefox:

    make gwt-debug DEV_BUILD_GWT_SUPER_DEV_MODE=1 DEV_EXTRA_BUILD_FLAGS_GWT_DEFAULTS="-Dgwt.userAgent=gecko1_8"

It’s Probably Not The Wi-Fi

After finishing up Mobility Field Day last week, I got a chance to reflect on a lot of the information that was shared with the delegates. Much of the work in wireless now is focused on analytics. Companies like Cape Networks and Nyansa are trying to provide a holistic look at every part of the network infrastructure to help professionals figure out why their might be issues occurring for users. And over and over again, the resound cry that I heard was “It’s Not The Wi-Fi”

Building A Better Access Layer

Most of wireless is focused on the design of the physical layer. If you talk to any professional and ask them to show your their tool kit, they will likely pull out a whole array of mobile testing devices, USB network adapters, and diagramming software that would make AutoCAD jealous. All of these tools focus on the most important part of the equation for wireless professionals – the air. When the physical radio spectrum isn’t working users will complain about it. Wireless pros leap into action with their tools to figure out where the fault is. Either that, or they are very focused on providing the right design from Continue reading

Settlement-Free Peering Requirements

Settlement-Free Peering Requirements.   I explained the Peering , Types of Peering basics in one of the previous posts. When we talk about peering, we generally mean settlement-free peering. But what are the common requirements for companies to peer with each other ?   Settlement-free peering is called as Internet Peering as well.   So, companies setup […]

IDG Contributor Network: How scientists are using big data to discover rare mineral deposits

Big data is shaking up the ways our entrepreneurs start their businesses, our healthcare professionals deliver care, and our financial services render their transactions. Now, big data’s reach has expanded so far that it’s revolutionizing the way our scientist search for gas, oil, and even valuable minerals.Searching under the surface of the earth for valuable mineral deposits has never been easy, but by exploiting recent innovations in big data that allow scientist to gleam the signal from the noise, experts are now capable of discovering and categorizing new minerals more efficiently than ever before.A new type of mining By mining big data, or by crunching huge sums of numbers to predict trends, scientist are now capable of mapping mineral deposits in new and exciting ways. Network theory, which has been used with great success in fields ranging from healthcare to national security, is one big data tool that scientist are coming to rely on more and more.To read this article in full or to leave a comment, please click here

Making Mainstream Ethernet Switches More Malleable

While the hyperscalers of the world are pushing the bandwidth envelope and are rolling out 100 Gb/sec gear in their Ethernet switch fabrics and looking ahead to the not-too-distant future when 200 Gb/sec and even 400 Gb/sec will be available, enterprise customers who make up the majority of switch revenues are still using much slower networks, usually 10 Gb/sec and sometimes even 1 Gb/sec, and 100 Gb/sec seems like a pretty big leap.

That is why Broadcom, which still has the lion’s share of switch ASIC sales in the datacenter, has revved its long-running Trident family of chips, which lead …
