In big data, investors from all over the world have found their next digital gold mine.So how exactly is the fight for control over lucrative IoT data playing out, and who are its biggest movers and shakers? How can companies small and large alike benefit from IoT data, and is this valuable resource really worth all of the hubbub it ceaselessly generates? A quick dive into the world of the IoT reveals the true value of its data, and shows that this new industry is only just getting started.To read this article in full or to leave a comment, please click here

If you haven’t found the tradeoff…

This week, I ran into an interesting article over at Free Code Camp about design tradeoffs. I’ll wait for a moment if you want to go read the entire article to get the context of the piece… But this is the quote I’m most interested in:

Just like how every action has an equal and opposite reaction, each “positive” design decision necessarily creates a “negative” compromise. Insofar as designs necessarily create compromises, those compromises are very much intentional. (And in the same vein, unintentional compromises are a sign of bad design.)

In other words, design is about making tradeoffs. If you think you’ve found a design with no tradeoffs, well… Guess what? You’ve not looked hard enough. This is something I say often enough, of course, so what’s the point? The point is this: We still don’t really think about this in network design. This shows up in many different places; it’s worth taking a look at just a few.

Hardware is probably the place where network engineers are most conscious of design tradeoffs. Even so, we still tend to think sticking a chassis in a rack is a “future and requirements proof solution” to all our network design Continue reading

How the internet of sound eliminates billions of IoT sensors

The Internet of Thing’s dirty little secret is the cost of deployment. For example, adding a low-cost motion sensor and radio to a traffic light to count passing vehicles before it leaves the factory is easy and inexpensive. The incremental cost of deployment is near zero, especially if low-power wide-area network (LPWAN) coverage or other low-cost communications coverage is available. But retrofitting the traffic light with sensors and radios will cost the municipality a public works truck roll, a crew, an electrician and a police traffic detail. Retrofits are expensive.Also on Network World: IoT standards battles could get messy Retrofitting the world for IoT is a data science and a sensor engineering task to study the IoT problem and find the simplest way to acquire the data. The question for the data scientist is what minimum data resolution will provide the desired result: How many sensors per unit of area and how many readings per time interval are necessary to solve the problem? The engineer must trade off sensor costs, radio costs and network availability, and power consumption versus available power sources.To read this article in full or to leave a comment, please click here

Cisco snaps up streaming-data startup Perspica

Cisco today announced plans to acquire San Jose-based startup Perspica, a company that specializes in using machine learning to analyze streams of data.Cisco says it will integrate the Perspica technology into its AppDynamics product, which provides network and application monitoring and analytics.One of the reasons it was attracted to Perspica is because of the company’s ability to monitor data in real-time, Cisco says. Being able to process data as it's created or very soon afterwards can speed the time that end users are able to gain insights from the data, the company says. “Perspica is known for its stream-based processing with the unique ability to apply machine learning to data as it comes in instead of waiting until it’s neatly stored,” says Bhaskar Sunkara, VP of Engineering at AppDynamics.To read this article in full or to leave a comment, please click here

ENOG 14 in Minsk

The 14th Eurasia Network Operator’s Group (ENOG 14) that was held on 9-10 October 2017 in Minsk, Belarus featured 234 participants from the host country, the Commonwealth of Independent States and Eastern Europe who came together to discuss operational issues and share expertise about evolving the Internet in the region. This was the second event of the year and was supported by the Internet Society, the RIPE NCC and hoster.by, with participation from our Deploy360 colleague Jan Žorž.

The first morning featured a couple of useful tutorials – one in Russian on DNSSEC operations that was led by Philipp Kulin and Dremuchij Les, and the other on Best Practices in IPv6 BGP led by Nathalie Trenaman and Massimiliano Stucchi (RIPE NCC).

The opening trio of talks focused on network security, starting with a general overview of how to operate a secure network from Ignas Bagdonas (Equinix). Kirill Malevanov (Selectel) then offered up his experiences of IPv4 prefix hijacking whereby network traffic is erroneously routed due to incorrect BGP announcements that are advertised either accidentally or deliberately. Alexander Azimov (Qrator Labs) followed-up with an overview of BGPsec that has recently been published as a RFC standard, and which aims to provide cryptographic verification Continue reading

Worth Reading: Stop Blaming Open Source

Despite the known threats, many organisations continue to point fingers at open source platforms for poor security practices. But do you really think these platforms are the ones that need to be blamed? Coming back to the Equifax example, soon after this, the company began to examine how the breach occurred, many unsubstantiated reports and theories surfaced in an attempt to pinpoint the vulnerability. One such theory included was the software (an open source framework) to be responsible for the breach. This gave rise to some of the most unwarranted open source shaming. —Nishtha Singh @ opensourceforu

Scotty Isn’t DevOps

I was listening to the most recent episode of our Gestalt IT On-Presmise IT Roundtable where Stephen Foskett mentioned one of our first episodes where we discussed whether or not DevOps was a disaster, or as I put it a “dumpster fire”. Take a listen here:

Around 13 minutes in, I have an exchange with Nigel Poulton where I mention that the ultimate operations guy is Chief Engineer Montgomery Scott of the USS Enterprise. Nigel countered that Scotty was the epitome of the DevOps mentality because his crazy ideas are what kept the Enterprise going. In this post, I hope to show that not only was Scott not a DevOps person, he should be considered the antithesis of DevOps.

Engineering As Operations

In the fictional biography of Mr. Scott, all he ever wanted to do was be an engineer. He begrudging took promotions but found ways to get back to the engine room on the Enterprise. He liked working starships. He hated building them. His time working on the transwarp drive of the USS Excelsior proved that in the third Star Trek film.

Scotty wasn’t developing new ideas to implement on the Enterprise. He didn’t spend his time figuring out Continue reading

Helping to make LuaJIT faster

Helping to make LuaJIT faster

This is a guest post by Laurence Tratt, who is a programmer and Reader in Software Development in the Department of Informatics at King's College London where he leads the Software Development Team. He is also an EPSRC Fellow.

Programming language Virtual Machines (VMs) are familiar beasts: we use them to run apps on our phone, code inside our browsers, and programs on our servers. Traditional VMs are useful and widely used: nearly every working programmer is familiar with one or more of the “standard” Lua, Python, or Ruby VMs. However, such VMs are simplistic, containing only an interpreter (a simple implementation of a language). These often can’t run our programs as fast as we need; and, even when they can, they often waste huge amounts of server CPU time. We sometimes forget that servers consume a large, and growing, chunk of the world’s electricity output: slow language implementations are, quite literally, changing the world, and not in a good way.

More advanced VMs come with Just-In-Time (JIT) compilers (well known examples include LuaJIT, HotSpot (aka “the JVM”), PyPy, and V8). Such VMs observe a program’s run-time behaviour and use that to compile frequently executed parts of the program Continue reading

Another DMVPN Routing Question

One of my readers sent me an interesting DMVPN routing question. He has a design with a single DMVPN tunnel with two hubs (a primary and a backup hub), running BGP between hubs and spokes and IBGP session between hubs over a dedicated inter-hub link (he doesn’t want the hub-to-hub traffic to go over DMVPN).

Here's (approximately) what he's trying to do:
