Ruby 3, whose goal is performance, concurrency, and Typing. Especially about performance, Matz stated “Ruby3 will be 3 times faster than Ruby2” a.k.a. Ruby 3x3.
Rails 6.1 has been released and wow does it have a lot of great stuff! It have implemented improvements to multiple databases, adding support for destroying associations in jobs instead of in-memory, turning errors into objects, and so much more.
Date, DateTime, Time and ActiveSupport::TimeWithZone objects using before? and after? in Rails 6.
before? and after? are aliases to < (less than) and > (greater than) methods respectively.
The Benchmark module provides methods for benchmarking Ruby code, giving detailed reports on the time taken for each task.
ActiveRecord::Store gives you a thin wrapper around serialize for the purpose of storing hashes in a single column. It’s like a simple key/value store baked into your record when you don’t care about being able to query that store outside the context of a single record.
At the end of May 2020, the Raspberry Pi Foundation announced Raspberry Pi OS, the new official operating system for the mini-computer that is replacing Raspbian.
The good news is that Raspberry Pi OS does support Docker and Docker Compose, in both the 32-bit and 64-bit variants! Read below on how to install it as well as Docker Compose.
Snap is a software packaging and deployment system developed by Canonical for the operating systems that use the Linux kernel. The packages, called snaps, and the tool for using them, snapd, work across a range of Linux distributions and allow upstream software developers to distribute their applications directly to users. Snaps are self-contained applications running in a sandbox with mediated access to the host system. Snap was originally released for cloud applications but was later ported to work for Internet of Things devices and desktop applications too.
Snap can be installed on a Raspberry Pi running the latest version of Raspberry Pi OS by opening a terminal and typing a couple of commands.
Users who stake on Raspberry Pis earlier than the Raspberry Pi 3 (such as the Original Raspberry Pi, Raspberry Pi Zero, and potentially the Raspberry Pi 2) may benefit from a significant increase in performance by enabling and/or increasing the size of the Raspberry Pi’s swap file.
k3sup is a light-weight utility to get from zero to KUBECONFIG with k3s(Lightweight Kubernetes, the certified Kubernetes distribution built for IoT & Edge computing) on any local or remote VM. All you need is ssh access and the k3sup binary to get kubectl access immediately.
The tool is written in Go and is cross-compiled for Linux, Windows, MacOS and even on Raspberry Pi. and uses ssh to install k3s to a remote Linux host. You can also use it to join existing Linux hosts into a k3s cluster as agents. First, k3s is installed using the utility script from Rancher, along with a flag for your host’s public IP so that TLS works properly. The kubeconfig file on the server is then fetched and updated so that you can connect from your laptop using kubectl.
nfs-client-provisioner chart will deploy the Kubernetes nfs provisioner. This provisioner is intended for connecting to a pre-existing NFS server, and not includes a built in NFS server. If you want a built in NFS Server, please consider using the nfs-client-provisioner - https://github.com/helm/charts/tree/master/stable/nfs-client-provisioner instead.
Pulumi - Modern Infrastructure as Code - https://www.pulumi.com/ is a Modern Infrastructure as Code (IaC) to create, deploy, and manage infrastructure on any cloud using familiar programming languages and tools.
This article is about how to use Pulumi, kubernetes (K8S) provider, Helm Chart and TypeScript SDK to deploy nfs-client-provisioner within Kubernetes (K8S).
NFS Server Provisioner is an out-of-tree dynamic provisioner for Kubernetes. You can use it to quickly & easily deploy shared storage that works almost anywhere.
This chart will deploy the Kubernetes external-storage projects nfs provisioner. This provisioner includes a built in NFS server, and is not intended for connecting to a pre-existing NFS server. If you have a pre-existing NFS Server, please consider using the NFS Client Provisioner [charts/stable/nfs-client-provisioner at master · helm/charts · GitHub - https://github.com/helm/charts/tree/master/stable/nfs-client-provisioner] instead.
