Drilling Down Into The Xeon Skylake Architecture

The “Skylake” Xeon SP processors from Intel have been in the market for nearly a month now, and we thought it would be a good time to drill down into the architecture of the new processor. We also want to see what the new Xeon SP has to offer for HPC, AI, and enterprise customers as well as compare the new X86 server motor to prior generations of Xeons and alternative processors in the market that are vying for a piece of the datacenter action.

That’s a lot, and we relish it. So let’s get started with a deep dive …

Worth Watching: The big four

Worth more than $2.3 trillion combined, the Big Four (Apple, Amazon, Facebook, and Google) continue to grab share from media companies, brands, and retailers. Scott Galloway, Professor of Marketing at the NYU Stern School of Business and Founder of L2, will showcase how the traditional rules of business don’t apply to the Big Four and identify ways that brands and companies can fight back. —Scott Galloway @ YouTube

SHA 2017 – bringing 100 gigabit to the tent

Every 4 years since its start back in 1989, a hacker/security conference takes place in the Netherlands. This summer, the eighth version of this conference, called Still Hacking Anyway 2017 (sha2017.org), will run between the 4th and 8th of August. The conference is not-for-profit and run by volunteers, and this year we’re expecting about 4000 visitors.

For an event like SHA, all the visitors need to connect to a network to access the Internet. A large part of the network is built on Cumulus Linux. In this article, we’ll dive into what the event is and how the network, with equipment sponsored by Cumulus, is being built.

What makes SHA 2017 especially exciting is that it is an outdoor event. All the talks are held in large tents, and they can be watched online through live streams. At the event site, visitors will organize “villages” (a group of tents) where they will work on several projects ranging from security research to developing electronics and building 3D printers.

Attendees will camp on a 40 acre field, but they won’t be off the grid, as wired and wireless networks will keep them connected. The network is designed Continue reading

Women Share Knowledge and Experience in Network Operator Groups in Africa

The Internet Society African Regional Bureau has worked with Network Operator Groups (NOGs) in Africa, providing financial and technical support to organize trainings and events at the local level. We recently shared many of their stories. There are also a number of NOGs that seek to attract women engineers to share knowledge and experience as well as to encourage young women to take up technology-related fields – which are largely perceived in the African region as “men only.” Here are their stories.

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"

    Wait about two minutes Continue reading
