Rebooting Linux systems with Ansible has always been possible, but was often tricky and error-prone. In Ansible 2.7, I am happy to say that rebooting Linux hosts with Ansible is now easier and can be done with a single task using the newly minted reboot plugin.
The win_reboot module was written by Matt Davis and included with Ansible 2.1. Rebooting Windows hosts is a much more common occurrence than rebooting Linux hosts. Necessity is the mother of invention, so it made sense that win_reboot appeared before the equivalent for Linux. And while less than elegant, it is possible to reboot Linux hosts using shell and wait_for or wait_for_connection[1].
Rebooting Linux systems with Ansible never felt right to me — much too error prone and finicky. It finally bugged me enough that I refactored win_reboot into reboot so Linux hosts could join the reboot party with their Windows counterparts.
When I set out to make the reboot plugin[2], the goal was to create a common class that win_reboot (and potentially others) could easily subclass to override specific parts of the reboot process. I was also working in reverse, deconstructing win_reboot into a new Continue reading
Have you ever tried to implement something new and run into others who are resistant to that change? In this Short Take, Russ explores the validity of the commonly used “It’s always been done that way” excuse for avoiding change.
The post Short Take – It’s Always Been Done That Way appeared first on Network Collective.
Security is a field of questions. We find ourselves asking
all kinds of them all the time. Who is trying to get into my network? What are
they using? How can I stop them? But I feel that the most important question is
the one we ask the least. And the answer to that question provides the
motivation to really fix problems as well as conserving the effort necessary to
do so.
If you’re someone with kids, imagine a conversation like
this one for a moment:
Your child runs into the kitchen with a lit torch in their hands and asks “Hey, where do we keep the gasoline?”
Now, some of you are probably laughing. And some of you are
probably imagining all kinds of crazy going on here. But I’m sure that most of
you probably started asking a lot of questions like:
Usually, the rest of the Five Ws follow Continue reading

The security skills gap is real, and it is a problem. But what if you could replace the most basic security jobs with an AI? According to Gunter Ollmann @CircleID, this is possible today. The next question you might want to ask is this: if AI’s replace all the entry level positions, then how are we going to train up senior level engineers? Remember that every hiring manager wants someone with ten years of experience on a product that has only been out for two years…

The community of Latin America and the Caribbean has maintained an incessant activity in community networks topics, particularly during September. This work has been reflected in various spaces, highlighting the Latin American Summit of Community Networks that took place in Argentina.
A Work with History
Interest in community networks in the Latin American and Caribbean region is not recent. At least since 2015, the operators of these networks have worked together, exchanging experiences and best practices. Part of the result of this collaboration is found in the documents of the Internet Governance Forum (IGF) Dynamic Coalition on Community Connectivity (DC3). It is worth mentioning that the creation of the Internet Society’s Special Interest Group on Community Networks (SIG CN) was announced during the closing ceremony of the IGF 2017 meeting.
The effort has been reflected in various spaces. This year, several operators of these networks were invited to participate in the Fifth Annual Latin America Spectrum Management Conference, held in Buenos Aires, Argentina, from September 5 to 7. On the last day of the Conference, the International Telecommunication Union (ITU) conducted a capacity building workshop on spectrum and community networks.

In addition to their participation in Continue reading
Welcome to Technology Short Take #105! Here’s another collection of articles and blog posts about some of the common technologies that modern IT professionals will typically encounter. I hope that something I’ve included here proves to be useful for you.

I know you’ll be back: interpretable new user clustering and churn prediction on a mobile social application Yang et al., KDD’18
Churn rates (how fast users abandon your app / service) are really important in modelling a business. If the churn rate is too high, it’s hard to maintain growth. Since acquiring new customers is also typically much more expensive than expanding in existing accounts, churn hits you twice over. So it’s really important to understand what causes users to churn in your business, and ideally to be able to predict users likely to churn so that you can intervene. This paper describes ClusChurn, the churn prediction system deployed at Snapchat.
It has been argued for decades that acquiring new users is often more expensive than keeping old ones. Surprisingly, however, user retention and its core component, churn prediction, have received much less attention from the research community… While this paper focuses on the Snapchat data as a comprehensive example, the techniques developed here can be readily leveraged for other online platforms, where users interact with the platform functions as well as other users.
The central idea in ClusChurn is to cluster users into clusters that are meaningful Continue reading
