Arve Knudsen's Blog

I’ve blogged for the first time for the Prometheus project!

Another year, another PromCon!

This year marks my debut as conference speaker!

I am very happy to be able to share with the world what I have been working on since July last year: Grafana Mimir!

Welcome to the second installation in my series on taking the Practical Networked Applications in Rust course, kindly provided by the PingCAP company, where you develop a networked and multithreaded/asynchronous key-value store in the amazing Rust languag…

The PingCAP company, makers of the TiDB NewSQL database and the TiKV key-value store, have kindly made publicly available, as well as open-sourced, a set of training courses that they call the "PingCAP Talent Plan".

Substrate is a framework for making custom blockchains, made available by Berlin based Parity Technologies, who are until now the best known for making the second-most popular (after the official one, Go Ethereum) client for the Ethereum blockchain, also…

At the behest of the excellent Quorum Control company, I have carried out my first foray into both Rust and Web Assembly (abbr.

My project Experimental Berlin received a nice mention in British newspaper The Guardian!

My pull request for updating the official Elasticsearch/Fluentd/Kibana logging add-on for Kubernetes to version 5.5.1 of Elasticsearch and Kibana was recently approved and merged into the master branch!

In my previous blog post I showed how to use the Kops tool to create a production ready Kubernetes cluster on Amazon Web Services (AWS).

Today I will be talking about Kops, which is an official tool for creating Kubernetes clusters on AWS, with support for GCE and VMware vSphere in alpha.

I’ve made a complementary route handling framework for Yoshua Wuyts' JavaScript SPA (Single Page Application) framework Choo: choo-routehandler.

When I recently implemented Google authentication in a Web app, I discovered that I fell victim to the browser’s built-in popup blocking mechanism, which would hide Google’s requisite login dialog.

I’m finally ready to share what I’ve been working on for the last few months, an online catalogue of underground cultural events in the city of Berlin: Experimental Berlin.

I’m happy to announce that I’ve taken over maintainership of the popular NPM package html-to-react, which currently has about 3600 downloads per month.

As part of developing MuzHack I had to implement a method of loading search results on demand, i.e. not everything at once.

Earlier, I wrote about zero downtime docker deployment with Tutum.

Electronic Beats Magazine did a quick writeup on my MuzHack project.

Amazon S3 is at the time of writing the premier file storage service, and as such an excellent choice for storing files from your Web application.

In this post I will detail how to achieve (almost) zero downtime deployment of Docker containers with the Tutum Docker hosting service.

I am pleased to announce that MuzHack members are now able to inform of their availability for workshops, which to me goes hand in hand with publishing open music hardware, as it allows makers to connect with their audience (and vice versa).

The Markdown editors in MuzHack are now sporting a help button, to display documentation about the supported Markdown syntax.

Stack Overflow and Markdown Stack Overflow is a familiar, and cherished, name to many a programmer these days.

So I gave the first presentation ever on MuzHack today, at the Norwegian sound research centre Notam.

A core concept in Meteor is reactivity.

In my search for a comprehensive logging solution for MuzHack that works in a Dockerized environment, more specifically Tutum, I came across Papertrail.

I just ported the Trello client API to a Meteor package, in order to be able to authorize my application before making actual API calls from the server side (let’s just avoid the hassle of cross-site scripting).

I’ve recently set up a Discourse forum on DigitalOcean, and was wondering how to implement automatic backups.

I recently installed Discourse on a CoreOS node at DigitalOcean.

For some months now I have been developing MuzHack, a platform for makers of music hardware to publish their designs.

As detailed in my previous blog post on Adding Support for Regular Expression Search in the Chromium Developer Console, some months ago I set out to make it possible to search for regular expressions in the Chromium/Google Chrome developer console.

As part of my work to port the ChucK music programming language to JavaScript, via the Emscripten C++ to JavaScript compiler, I’ve implemented a Gradle build script for it (instead of the original Makefile).

In the time since my first post on accessing non-virtual DOM nodes with Mercury / virtual-dom, I’ve learnt that my approach wasn’t as sound as I initially thought.

I am facing the need to upload pictures to Amazon S3 in my Meteor application, MuzHack.

At work, we are using the Mercury JavaScript UI library, which is a more functional alternative to React (at least this is my understanding of it).

I have recently implemented continuous deployment of my MuzHack Web application to the Docker hosting service Tutum, in both production and staging versions.

Today I wrote a Python script in order to insert data into Meteor’s MongoDB instance, and the first question that came up was how to get hold of the connection parameters.

In my Meteor-based project MusitechHub, I recently had to figure out how to set page title dynamically for certain pages.

Last Thursday (the 5th of February) I gave a talk on my project ChucKJS at the Berlin NodeJS meetup.

Chromium/Google Chrome is my hands-down favourite browser for developing Web sites in, owing to its incredibly sleek developer tools.
