Amazon Cognito is a managed service that provides federated identity, access controls, and user management with multi-factor authentication for web and mobile applications.

NHM is a fast HTML to markdown converter, compatible with both node and the browser. We had a need to convert gigabytes of HTML daily very quickly. All libraries we found were too slow with node.

At fleetster, we have our own instance of GitLab and we rely a lot on GitLab CI.

Last week I implemented a search functionality for a static website with Lunr.js. The way I implemented the search system, depends on 2 files to work, the pagesData.json and the searchIndex.json.

I recently came back from connect.tech (one of my favorite conferences). I had the honor of giving not one, but two different talks. One of them was on static sites, or the JAMstack. This is a topic I've covered many times in the past, but it had been a while since I gave a presentation on it.

Designed to be small, yet full featured, Lunr enables you to provide a great search experience without the need for external, server-side, search services. Add powerful language processors to give more accurate results to user queries, or tweak the built-in processors to better fit your content.

JSON Web Tokens are an open, industry standard RFC 7519 method for representing claims securely between two parties. JWT.IO allows you to decode, verify and generate JWT.

Today we’ll experiment some more with the adjacent and general sibling combinator and the :checked pseudo-class. Using hidden inputs and labels, we will create an accordion that will animate the content areas on opening and closing.

In a recent update to my site, I decided to show a helpful notice in my footer that timestamps my build, writes the abbreviated commit hash from Git, and links to the changeset on my GitHub repo for ease of reference.

Gradle plugin for managing Docker images and containers using via its remote API. The heavy lifting of communicating with the Docker remote API is handled by the Docker Java library.

Testing asynchronous systems is hard. Not only does it require handling threads, timeouts and concurrency issues, but the intent of the test code can be obscured by all these details.

Recently I contributed an addition to the Bookwyrm social reading software to enable "remote following". Bookwyrm uses the ActivityPub protocol for decentralised online social interaction.

Today we’ll be looking at how to connect the protocols powering Mastodon in the simplest way possible to enter the federated network.

Frameworks Bonfire: An extensible framework with a big focus on customisation and flexibility. Can be used to build new federated apps while focusing on a specific use case rather than reimplementing lots of boilerplate AGPL-3.

If you have data for which a digital signature was generated, you can verify the authenticity of the signature. To do so, you need In this example you write a VerSig program to verify the signature generated by the GenSig program.

Java 16 introduces Records. While this version of records is fantastic, it's currently missing some important features normally found in data classes: a builder and "with"ers. This project is an annotation processor that creates: Hat tip to Benji Weber for the Withers idea.

This is going to be a look at my philosophy and views on ActivityPub and why I believe the solutions to ActivityPub criticisms must come from communities. I believe there needs to be a clear way for communities to form and build upon the ActivityPub specification.

This is a Java implementation of the JSON-LD 1.0 specification and the JSON-LD-API 1.0 specification. The Options specified by the JSON-LD API Specification are accessible via the com.github.jsonldjava.core.JsonLdOptions class, and each JsonLdProcessor.

In this tutorial, we’ll learn how to transform a Java Object to JSON-LD and vice versa. Also learn how to verify the schema of JSON-LD. JSON-LD is a JSON-based format which is used to represent structured data and linked data. Schema of JSON-LD can be found in documentation of schema.org.

Using openssl, the command is... However, I will need to do this often and have written a Java class that handles this and more (my application is mostly .jsp with Tomcat and Apache). When I try run the same command from Java using Runtime.

In this article, we are going to talk about Java’s Service Provider Interface (SPI). We will have a short overview of what the SPI is and describe some cases where we can use it. Then we will give an implementation of an SPI for a practical use case.

In this blog post, I’m going to explain how you can make use of the Micronaut framework to organize your project code in such a way that you can externalize and modularize some of your @Beans. These beans can be used as “common” and can be shared between several projects.

I recently needed a simple example of an SPI implementation I could send around as copy and paste template. After some looking around I found some tutorials, but most of them were rather heavy in the implementation and are thereby loosing the point of being a simple extension system within the JDK.

Schema-org-java is a library for creating schema.org entities. The entities can be easily generated with the maven plugin, programmatically, or in command line.

Null dereferencing is a common type of programming error in Java. On Android, NullPointerException (NPE) errors are the largest cause of app crashes on Google Play.

To load calsses in runtime java uses ClassLoader mechanism which is based on next core principles: delegation - by default uses parent-first delegation, - child ClassLoader will be used if parent is not able to find or load class.

JCL is a configurable, dynamic and extensible custom classloader that loads java classes directly from Jar files and other sources. The motivation was to create isolated classloaders, which can be easily integrated with IoC frameworks like Spring and with web applications.

As projects grow in size and complexity and otherwise mature, they tend to accumulate a large collection of automated tests. Testing your software at multiple levels of granularity is important to surface problems quickly and to increase developer productivity. In Gradle 7.

Remote procedure call (RPC) systems, including Java RMI, are synchronous -- the caller must block and wait until the called method completes execution, and thus offer no potential for developing loosely coupled enterprise applications without the use of multiple threads.

Sealed types, switch expressions, and record types. Here are just a few new features introduced in the latest Groovy 4.0 release. In this video, I want to show you ten things that make Groovy 4.0 amazing. And to keep this video short, we’re not going to dive deep into each of them.

Besides the criticism of Serverless computing [1], it is quite popular these days especially the AWS lambda functions. In this blog, we will deploy OpenWhisk one of the popular opensource serverless computing platforms along with Kubernetes to create a serverless computing environment.

K3s is a highly available, certified Kubernetes distribution designed for production workloads in unattended, resource-constrained, remote locations or inside IoT appliances.

What is k3d?¶ k3d is a lightweight wrapper to run k3s (Rancher Lab’s minimal Kubernetes distribution) in docker. k3d makes it very easy to create single- and multi-node k3s clusters in docker, e.g. for local development on Kubernetes.

The snmp_exporter is one of the trickier Prometheus components to set up because there’s a few moving parts involved in a full configuration and because of the need to run an extra tool to generate the snmp.yml config file from the ever-mysterious “MIBS”.

In this blog entry I would like to explain how to write an annotation processor. First, I am going to explain to you what annotation processing is, what you can do with that powerful tool and finally what you cannot do with it.

JavaPoet is a Java API for generating .java source files. Source file generation can be useful when doing things such as annotation processing or interacting with metadata files (e.g., database schemas, protocol formats).

Developers are accustomed to using their own tooling and writing in familiar languages.

CDK Aspects are a powerful tool provided by the AWS Cloud Development Kit (CDK). They are utilizing the Visitor Pattern. By applying a CDK Aspect to a specific scope, you get access to every child node within it. You can inspect them or alter them.

Serverless functions are modular pieces of code that respond to a variety of events. It's a fast and efficient way to run single-purpose services/functions.

Monitoring your services is production is a must for most serious businesses. People who develop on AWS, typically use AWS Cloudwatch for setting up monitoring. Typical metrics to monitor are latency, faults, invocations, throttles etc.

Argo CD is an extremely popular declarative, GitOps-based continuous delivery tool. It is an open source tool and part of the Cloud Native Computing Foundation (CNCF). It is effortless to install and set up, and it offers various features and a jazzy UI to manage all your application requirements.

This page is generated using information from: https://github.com/digitalocean/container-blueprints/blob/master/DOKS-CI-CD/README.md. This blueprint will show you how to implement a CI/CD solution using free and popular open source implementations that run on Kubernetes clusters natively.

The kubernetes_manifest resource can be used to create any Kubernetes API resource, including custom resource definitions. See the provider documentation page for more information on the additional attributes available for this resource.

The object destructuring is a useful JavaScript feature to extract properties from objects and bind them to variables.

This tutorial is a work in progress. Some sections may be incomplete, out of date, or missing. We're working to update it.

Web frameworks like Spring and ASP.NET Core have dependency injection solutions built in. Unfortunately, that’s not the case for most Node.js web frameworks, including Express.js.

Dependency injection is an essential concept in object-oriented programming. It is a way to decouple the creation of objects from their usage. In this article, we will learn what dependency injection is and how we can use it in Node.js applications using the TypeDI library.

Node.js library that generates Typescript clients based on the OpenAPI specification. There's no named parameter in JavaScript or TypeScript, because of that, we offer the flag --useOptions to generate code in two different styles.

In this blog post, I’m using ActivityPub.Academy (see the announcement post) to explore the ActivityPub protocol.

We all know what JSON-LD is: JSON with a @context field tacked on top, right? That’s pretty much all it is. Except sometimes you see an @id field, which, sure, that makes sense. And sometimes the @context field is multiple URLs, which seems odd — because how do they mix? Well, no worries.

Lightweight, solid, framework agnostic and easy to use library written in TypeScript to deal with Cross Cutting Concerns and improve modularity in your code. This library provides a straightforward manner to implement Advices in your app.

Executors come with their own set of challenges and pitfalls that developers must be aware of to avoid potential issues. In the world of concurrent programming, Java's Executors framework has been a boon for developers looking to manage and coordinate multiple tasks efficiently.

If you need to run a command periodically on your Linux server, you might consider using a Systemd timer instead of a cron job. Systemd timers offer more control over your command and are more flexible than Cron jobs. Here's a quick comparison between the two:

With a greater proliferation of devices than ever before, we developers can no longer rely on viewport size as the factor that determines the styles we serve up to our website users.

Because Scroll-Driven Animations are only active when there is scrollable overflow, it is possible to use them as a mechanism to detect if an element can scroll or not.
