12 open source tools for natural language processing

It would be easy to argue that Natural Language Toolkit (NLTK) is the most full-featured tool of the ones I surveyed. It implements pretty much any component of NLP you would need, like classification, tokenization, stemming, tagging, parsing, and semantic reasoning. And there’s often more than one implementation for each, so you can choose theexact algorithm or methodology you’d like to use.

Kubernetes End-to-end Testing for Everyone

Implementing a test suite. This is the main focus of this blog post. The Kubernetes E2E framework is written in Go.

A Guide to Kubernetes Admission Controllers

Kubernetes has greatly improved the speed and manageability of backend clusters in production today. Kubernetes has emerged as the de facto standard in container orchestrators thanks to its flexibility, scalability, and ease of use. Kubernetes also provides a range of features that secure production workloads.

Detecting the Kubernetes API server DoS vulnerability (CVE-2019-1002100).

Recently, a new Kubernetes related vulnerability was announced that affected the kube-apiserver. This was a denial of service vulnerability where authorized users with write permissions could overload the API server as it is handling requests. The issue is categorized as a medium severity (CVSS score of 6.5) and can be resolved by upgrading the kube-apiserver to v1.11.8, v1.12.6, or v1.13.4.

Using Gloo as an ingress gateway with Istio and mTLS (updated for Istio 1.1!)

Init Container Build Pattern: Knative build with plain old Kubernetes deployment

Knative and Solo.io Gloo

Knative is talked about a great deal, especially around how its capabilities can help provide more standard building blocks on top of Kubernetes for building microservices and serverless like services, e.g., scale to zero, and scale on demand. Knative high level has three capability areas: building, serving, and eventing. This post will provide some examples around Knative Build and Knative Serving with Solo.io Gloo.

Vault 1.1

The release also includes additional new features, secure workflow enhancements, general improvements, and bug fixes. The Vault 1.1 changelog provides a full list of features, enhancements, and bug fixes. Vault agent now supports client-side caching of leased secrets.

Announcing Istio 1.1

Since we released 1.0 back in July, we’ve done a lot of work to help people get into production. Not surprisingly, we had to do some patch releases (6 so far!), but we’ve also been hard at work adding new features to the product. The theme for 1.1 is Enterprise Ready.

Architecting Istio 1.1 for Performance

Hyper-scale, microservice-based cloud environments have been exciting to build but challenging to manage. Along came Kubernetes (container orchestration) in 2014, followed by Istio (container service management) in 2017. Both open-source projects enable developers to scale container-based applications without spending too much time on administration tasks.
