Episode 33 – The Importance Of Breaking Things

Conventional wisdom tells us that a network that never breaks is the most resilient, but practice tells us otherwise. In this episode we explore the value of chaos engineering and how breaking your network intentionally can make it stronger.

Getting To The Root Of Security With Trusted Silicon

The increasingly distributed nature of computing and the rapid growth in the number of the small connected devices that make up the Internet of Things (IoT) are combining with trends like the rise of silicon-level vulnerabilities highlighted by Spectre, Meltdown, and more recent variants to create an expanding and fluid security landscape that’s difficult for enterprises to navigate. …

Reality Check: Self-Driving Networks

I stumbled upon an article with an interesting title (and worth reading): To Make Self-Driving Cars Safe, We Also Need Better Roads and Infrastructure… and thought about the claims along the lines of “if they managed to solve the self-driving cars challenge, it’s realistic to expect self-driving networks” made in Self-Driving Networks podcast episode. Turns out the self-driving cars problem is far far away from being solved.

AfPIF 2018 Kicks Off

The ninth edition of Africa Peering and Interconnection Forum (AfPIF) kicked off today, with more than 400 tech executive in attendance.

This year, the forum was organized and held jointly with iWeek- South Africa ISP Association’s premier tech event. The event is underway at the Cape Town International Convention Center.

This year’s event is dubbed AfPIF@iWeek has attracted tech executives, chief technology officers, peering coordinators and business development managers, Internet service providers and operators, telecommunications policymakers and regulators, content providers, Internet Exchange Point (IXP) operators, infrastructure providers, data center managers, National Research and Education Networks (NRENs), carriers, and transit providers.

The sessions started with an introduction by Nishal Goburdhan, a veteran of AfPIF, who traced the history of AfPIF, from its conception to the community event it is. The community took over the program three years ago, determining the speakers and the conference content.

How can you take advantage of AfPIF? Nishal suggested that the participants use peering personals sessions; this is like speed dating for networks – members give details of their AS numbers, where they peer, peering policy, contact information, and explain why other participants should peer with them. At the end of every session, participants get a Continue reading

Snorkel: rapid training data creation with weak supervision

Snorkel: rapid training data creation with weak supervision Ratner et al., VLDB’18

Earlier this week we looked at Sparser, which comes from the Stanford Dawn project, “a five-year research project to democratize AI by making it dramatically easier to build AI-powered applications.” Today’s paper choice, Snorkel, is from the same stable. It tackles one of central questions in supervised machine learning: how do you get a large enough set of training data to power modern deep models?

…deep learning has a major upfront cost: these methods need massive training sets of labeled examples to learn from – often tens of thousands to millions to reach peak predictive performance. Such training sets are enormously expensive to create…

Snorkel lets you throw everything you’ve got at the problem. Heuristics, external knowledge bases, crowd-sourced workers, you name it. These are known as weak supervision sources because they may be limited in accuracy and coverage. All of these get combined in a principled manner to produce a set of probability-weighted labels. The authors call this process ‘data programming’. The end model is then trained on the generated labels.

Snorkel is the first system to implement our recent work Continue reading

A Simple Kubernetes Context Switcher

I recently needed to find a simple way of switching between Kubernetes contexts. I already use powerline-go (here’s the GitHub repo), which allows me to display the Kubernetes context in the prompt so I always know which context is the active (current) context. However, switching between contexts using kubectl config set-context <name> isn’t the easiest approach; not to mention it requires merging multiple config files into a single file (which is itself a bit of a task). So, I set out to create a simple Kubernetes context switcher—and here’s the initial results of my efforts.

Before I go any further, I’d like to stress 2 important points. First, I’m not a programmer, so keep that in mind. Second, this is a simple Kubernetes context switcher—it’s not meant to address any and every possible use case out there, nor do I claim any sort of sophistication in the code.

With those disclaimers out of the way, allow me to introduce kcs: the simple Kubernetes context switcher. kcs is built on the idea that it’s easiest to manage Kubernetes contexts in their own files, rather than trying to merge config files. So, it makes the assumption that you’ll store your Continue reading

Refresh Stale DNS Records on 1.1.1.1

You can now refresh 1.1.1.1’s DNS cache for domain names by using the purge cache tool. This is useful for domain owners who have updated their DNS records and want to make sure it is reflected for people who are using 1.1.1.1 as their public DNS resolver.

When a client queries for a domain against 1.1.1.1, the resolver returns the IP address from its cache. The cache TTL for a DNS entry is 3 hours. If the host specifies a cache TTL that is shorter than 3 hours, the resolver respects that. This means, when a domain owner changes the DNS host from one to another, in the worst case, she will have to wait for at least 3 hours before the old IP address expires from 1.1.1.1’s cache. With the help of the purge cache tool, a domain owner can now easily refresh 1.1.1.1’s DNS cache and will not have to wait for the cached entry to expire.

To purge a DNS record, you enter the name of your domain, pick the DNS record type and hit the ‘Purge Cache’ button.

How we chose the 10 AI-powered startups to watch

The selection process for this roundup started back in May at the tail-end of a previous, but closely related competition, 10 Hot IoT startups to watch.AI wasn’t a key selection criterion then. Some startups had it, some did not, but enough of them focused squarely on AI that it made sense to look more closely at this subsector of the overall IoT market.[ Check out our corporate guide to addressing IoT security. ] This roundup considered about 20 companies from the previous contenders that had strong AI components. Notice of the search for candidates was posted on HARO, LinkedIn, Twitter, etc., and all told, just under 40 startups were considered.To read this article in full, please click here

BrandPost: Why Smart Cities Need Adaptable Pipes

Daniele Loffreda, Senior Advisor, Industry Marketing For cities to evolve and realize the full benefits of becoming “smart,” they will require real-time access to multiple sources of data from different locations. Ciena’s Daniele Loffreda explains what is needed from the next-generation of networks to make smart cities a reality.Apple CEO, Tim Cook, said it best during a commencement address at the prestigious Massachusetts Institute of Technology (MIT) last year when he proclaimed science and technology are worthless, if they aren’t motivated by the desire to help people. This belief can be just as correctly applied to the planning and development of smart city initiatives.To read this article in full, please click here

Internet Native Applications

I grew up with DOS and Windows 3.1. I remember applications being fast - instant feedback or close to it. Today, native applications like Outlook or Apple Mail still feel fast - click compose and the window is there instantly and it feels snappy. Internet applications do not.

My first Internet experience was paying $30 for a prepaid card with 10 hour access over a 14.4k modem. First, it was bulletin boards and later IRC and the WWW. From my small seaside town in Australia, the Internet was a window into the wider world, but it was slooooooow. In a way, it didn’t matter. The world of opportunities the Internet opened up, from information to music, to socializing and ecommerce, who cared if it was slow? The utility of the Internet and Internet applications meant I would use them regardless of the experience.

Performance improved from the 90s, but in 2008 when I switched from Outlook downloading my Yahoo! email over IMAP to Gmail in the browser, it wasn’t because it was faster - it wasn’t - it was because features like search, backed up mail, and unlimited storage were too good to resist. The cloud computing power Continue reading

Worth Reading: Practice Hours

Often times musicians have “sacred” practice hours. They don’t do it for an artist, band, or for anyone other than themselves. It’s their time to sit down and focus on a technique, song that they want to learn, or whatever their heart desires. —Stephanie Winn Provence @Free Code Camp
