Gopher by Renee French. Portability isn’t the first thing that comes to mind when thinking about low-level, compiled programming languages. Languages which compile to machine code generate binaries that are specific to a CPU architecture and possibly an OS. Interpreted languages on the other hand (Python, Ruby, JavaScript), and also compiled languages which run on a virtual machine (Java, Scala), are usually praised for their portability. https://liebermann.io/whoami/ Sat, 10 Jun 2017 19:23:17 +0000 https://liebermann.io/whoami/ My name is Johanan Liebermann. I am a self-taught software developer with multiple areas of interest and a focus on open-source software. Some areas I care about (and potentially have some knowledge about) are network technologies (IP, voice, optical), distributed systems, software containers, cloud infrastructure, CI/CD and security. I am an autodidact who loves learning and I invest a lot of time and energy in expanding my knowledge in various fields—right now I focus on math. https://liebermann.io/2016/10/17/programming-in-go-first-impressions/ Mon, 17 Oct 2016 23:36:07 +0000 https://liebermann.io/2016/10/17/programming-in-go-first-impressions/ Recently I started experimenting with Go, and I want to share my thoughts and experiences with the language so far. Go is a relatively new programming language. Since its announcement in 2009 by Google it’s been gaining a lot of traction. Among the trending programming languages these days, Go is quite unique. On one hand, it is relatively easy to learn, its syntax resembles interpreted languages at times and it offers features like garbage collection and memory safety. https://liebermann.io/2016/10/02/docker-on-aws-the-right-way/ Sun, 02 Oct 2016 21:56:45 +0000 https://liebermann.io/2016/10/02/docker-on-aws-the-right-way/ About a month ago I presented a webinar on running Docker environments on AWS. The webinar was organized by my workplace, emind. If you’re running—or planning to run—production Docker environments on AWS, be sure to check it out as you may find some useful information there. I’d love to hear your thoughts and comments if you have any. https://liebermann.io/2016/06/16/the-hidden-meaning-behind-aws-service-names/ Thu, 16 Jun 2016 18:53:00 +0000 https://liebermann.io/2016/06/16/the-hidden-meaning-behind-aws-service-names/ Elastic Beanstalk, Route 53, Redshift—ever wondered about the meaning of these strange AWS service names? I have, and I’ve got some theories about them. None of the following has been confirmed by Amazon—it’s just my ideas on how the guys at AWS have come up with these mysterious names for some of their services. Elastic Beanstalk Elastic Beanstalk is a reference to the English fairy tale Jack and the Beanstalk. https://liebermann.io/2016/05/24/docker-for-mac-windows-beta/ Tue, 24 May 2016 19:49:00 +0000 https://liebermann.io/2016/05/24/docker-for-mac-windows-beta/ Already addicted to Docker? Great, me too. Don’t know Docker yet? Stop reading this and try it out (but do come back later). About two months ago the guys at Docker have launched a new, limited beta for a Docker version which runs natively on Mac and Windows. Well, almost natively to be precise. As you might be aware, Docker leverages a Linux feature called Linux Containers or LXC, which unsurprisingly requires Linux in order to run. https://liebermann.io/2016/02/20/stop-trying-to-avoid-infrastructure-failures-count-on-them/ Sat, 20 Feb 2016 16:25:00 +0000 https://liebermann.io/2016/02/20/stop-trying-to-avoid-infrastructure-failures-count-on-them/ With the massive migration of companies from the traditional data center to the cloud, it is necessary to adopt new perceptions and design principles when doing so. Some of the cloud service providers give their customers nearly unlimited flexibility in designing their application’s architecture, however this fact is worthless if you, as the customer, don’t leverage this flexibility to build a durable and reliable application. With Flexibility Comes Responsibility Compared to the traditional data center, the cloud is phenomenally flexible. https://liebermann.io/projects/ Mon, 01 Jan 0001 00:00:00 +0000 https://liebermann.io/projects/ I am a co-maintainer of the following projects: Lokomotive—an open-source Kubernetes distribution from Kinvolk. MetalLB—a network load balancer for Kubernetes clusters running on bare metal. I am a contributor to the following projects: OpenTelemetry—the new observability standard for cloud-native software. Cassandra Operator—a Kubernetes operator for Cassandra databases by Instaclustr. I am the original author of Clisso—a utility which allows using cloud single sign-on (SSO) from the command line. https://liebermann.io/talks/ Mon, 01 Jan 0001 00:00:00 +0000 https://liebermann.io/talks/ A list of talks, webinars and meetups I’ve spoken at.
