Using Go as a scripting language in Linux

Using Go as a scripting language in Linux

At Cloudflare we like Go. We use it in many in-house software projects as well as parts of bigger pipeline systems. But can we take Go to the next level and use it as a scripting language for our favourite operating system, Linux?

Why consider Go as a scripting language

Short answer: why not? Go is relatively easy to learn, not too verbose and there is a huge ecosystem of libraries which can be reused to avoid writing all the code from scratch. Some other potential advantages it might bring:

  • Go-based build system for your Go project: go build command is mostly suitable for small, self-contained projects. More complex projects usually adopt some build system/set of scripts. Why not have these scripts written in Go then as well?
  • Easy non-privileged package management out of the box: if you want to use a third-party library in your script, you can simply go get it. And because the code will be installed in your GOPATH, getting a third-party library does not require administrative privileges on the system (unlike some other scripting languages). This is especially useful in large Continue reading

Is the IoT backlash finally here?

As pretty much everyone knows, the Internet of Things (IoT) hype has been going strong for a few years now. I’ve done my part, no doubt, covering the technology extensively for the past 9 months. As vendors and users all scramble to cash in, it often seems like nothing can stop the rise IoT.Maybe not, but there have been rumblings of a backlash to the rise of IoT for several years. Consumer and experts worry that the IoT may not easily fulfill its heavily hyped promise, or that it will turn out to be more cumbersome than anticipated, allow serious security issues, and compromise our privacy.To read this article in full, please click here

Automation: Easy Button vs Sentient Voodoo Magic Button

Automation has become this “all-encompassing thingy” much like SDN. It’s a software industry problem and it’s critical more now than ever that we do not slip backwards by trying to drag a broken idea forwards.

This post contains nothing new and should act as polish on common sense. If you’re on the look-out for removing pain and getting stuff done with the power of automation, read on.

If your processes and operating handbook for your team or organisation is in disarray, it will not come too much as a surprise when your automation team implements something inherently broken. Naturally the technology, shortly followed by the team will take a boat load of blame. Whilst artificial intelligence and machine learning is promising, unless you have a team of subject matter experts or have very deep pockets, automation today is simple and the patterns are hard wired. Even decision making logic has been should be pre-thought. Automation platforms do not today think creatively and do not possess sentient capabilities. If they did, I would be on a beach right now drinking mojitos, smoking cigars and wondering what to do with my time on this rock (the answer by the way would be Continue reading

On the ‘net: Spectre, Meltdown, and Flexible Scaleout

The recent Meltdown and Spectre attacks illustrate the problematic nature of modern computing systems. While the earlier Rowhammer attack could read or attack one process running in a virtual environment from another process running on the same processor, the Meltdown and Spectre attacks are of a completely different class, enabling a process to read large amounts of information from another process’ memory space. @GestaltIT

Context-Aware Micro-segmentation – Remote Desktop Session Host Enhancements for Citrix

In a previous post by my colleague, Stijn, discussed the new changes to how NSX for vSphere 6.4 handles Remote Desktop Session Host, RDSH, systems with the Identity-based Firewall and context-aware micro-segmentation.

RDSH is an underlying technology from Microsoft that many vendors take advantage of to provide overlay management and application deployment technologies for.  In this post, we’re going to discuss how NSX 6.4 and the new changes to support RDSH hosts works with Citrix XenApp systems.

Citrix XenApp can provide multiple users the ability to connect to a single system to access their applications using the RDSH technology.  These users can be of the same type, for example all HR users, or of multiple types, HR and Engineering users.  NSX has supported User Identity based firewalling for Virtual Desktops since the 6.0 release, but it did not address RDSH in which multiple user sessions are connecting to the same host  This meant less flexibility in controlling what users could access data center application servers without isolating one set of users to one RDSH server.  This model created a very rigid architecture for XenApp customers to follow, which brought about the use of Continue reading

Video Series: Modernizing .NET Apps for Developers

MTA for Devs

 Docker Enterprise Edition (EE)  is the container platform for modernizing your existing applications, and running them in the cloud or on-premises. You can take monoliths and run them in containers with no code changes, and that gets you portability, security and efficiency.

Running in Docker is also a great starting point for modernizing the application architecture. You can breaking down the monolith into smaller, independent components which makes it easier to deploy updates, manage scale and introduce new technologies.

This new video series covers app modernization, for .NET developers and architects. It walks through the evolution of a monolithic ASP.NET 3.5 app to a distributed application running across multiple containers, using the Docker platform to plug everything together and adding features with great open-source software from the Docker ecosystem.

This is not a full re-architecture to microservices – for large .NET apps that would be a 12 month project. This series uses a feature-driven approach, taking key features out of the monolith to fix performance issues, add new functionality and support fast application updates.

Part 1 introduces the series, talks about what “modernization” means and then gets started – this is a very demo-heavy video series, where you’ll see lots Continue reading

Worth Reading: Three strategies for navigating moral disagreement

We in America and Western Europe, and by now many other places in the world, have this idea of people as fundamentally rational. On this account, our profound cognitive abilities are designed to help us discover objective truths about the world through logical argument and empirical observation. Contemporary research in cognitive science, psychology and related fields paints a much different picture. —Musa Al-Gharbi @Heterodox Academy

The Future of Online Privacy and Personal Data Protection in Africa

African experts are gathered for two days (19-20 February 2018) in Addis Ababa, Ethiopia to contribute to the development of the African Privacy and Personal Data Protection Guidelines. The meeting, facilitated by the African Union Commission (AUC) and supported by Internet Society, explored the future of privacy and data protection and provided some practical suggestions that African states can consider in implementing the Malabo convention provisions related to online privacy. The guidelines are aimed at empowering citizens, as well as establishing legal certainty for stakeholders through clear and uniform personal data protection rules for the region.

The expert meeting comes amidst growing concern across the world on the need to prepare for the EU General Data Protection Regulation (GDPR), which will be enforced on 25 May 2018. The expert meeting is rather focused on creating general principles for African member states in developing good practices now and in the future. The project, a partnership of the AUC and the Internet Society, comes as a follow up to the recommendations of the Africa Infrastructure Security Guidelines, developed in 2017 to assist speed up their adoption and subsequent ratification of the Malabo Convention.
