The Future of Virtualization
In this eBrief from SDxCentral, we take an in-depth look at the future of virtualization and the role of intent-based networking and what it means for service providers and enterprises.

Currently, 53% of the world’s population is offline due to factors such as high cost of Internet infrastructure and lack of relevant local content. Internet access remains unaffordable in many economies in transition where people have to choose between the Internet and other vital necessities such as food and health. Maybe one day we will look back at this historic moment in which Community Networks were paving the way for equitable and meaningful access to technology.
Community Networks are an emerging complementary and sustainable solution to address the connectivity gap existing in underserved urban and rural areas around the world. Such networks rely on the active participation of local communities in the development and management of shared Internet infrastructure as a common resource. Existing examples provide concrete evidence that community network development can prompt positive effects to help communities leverage on technology for socioeconomic empowerment. We have gained experience from Guifi.Net, Zenzeleni Network, Rhizomatica and Wireless For Communities, all successful projects proving that the technical side of the community network model can be replicated.
I asked Josephine Miliza a few questions to get deeper insight into the project. Josephine is a network engineer with a Continue reading
Facebook developed the osquery security framework to monitor its own infrastructure before open sourcing it in 2014.
Wonderful, honest review story about migrating a customer data centre and their office in the same day
The networking giant is partnering with Google to enter the cloud market, but will Google’s help be enough to put it on the path to cloud prosperity?
During last week’s SIGS Technology Conference I had a keynote presentation about the three paths of enterprise IT.
Unfortunately, the event wasn’t recorded, but you can view the presentation here. Contact me if you have any questions, or Irena if you'd like to have a similar keynote for your event.
Debugging with intelligence via probabilistic inference Xu et al., ICSE’18
Xu et al. have built a automated debugger that can take a single failing test execution, and with minimal interaction from a human, pinpoint the root cause of the failure. What I find really exciting about it, is that instead of brute force there’s a certain encoded intelligence in the way the analysis is undertaken which feels very natural. The first IDE / editor to integrate a tool like this wins!
The authors don’t give a name to their tool in the paper, which is going to make it awkward to refer to during this write-up. So I shall henceforth refer to it as the PI Debugger. PI here stands for probabilistic inference.
We model debugging as a probabilistic inference problem, in which the likelihood of each executed statement instance and variable being correct/faulty is modeled by a random variable. Human knowledge, human-like reasoning rules and program semantics are modeled as conditional probability distributions, also called probabilistic constraints. Solving these constraints identifies the most likely faulty statements.
In the evaluation, when debugging problems in large projects, it took on average just 3 interactions with a developer to find the Continue reading
If the ecosystem for Arm processors is going to grow in the HPC arena, as many think it can, then someone has to make the initial investments in prototype hardware and help cultivate the software stack that will run on current and future Arm platforms. …

As you may have noticed, our shiny new website has some speed issues. It is slow for many visitors. Over the past few months we’ve worked on a number of potential changes to improve the site performance. One big change we’re making is to move to a different hosting provider.
That change will happen tomorrow – Tuesday, 19 June 2018 at 13:00 UTC.
Assuming all goes well, you shouldn’t really notice – except that the site should be faster! But if you happen to be browsing the site around 13:00 UTC, you might see some glitches on pages while the DNS magic happens and we change to pointing to the new server.
Once we’ve made this migration, I’ll write more about what we have done and how it has helped our site’s performance. Meanwhile, I just wanted to give a quick alert about this impending change to anyone viewing our site.
