This post outlines the use of Google’s diff-match-patch library to generate patches that can be translated to operations against an AutoMerge.Text CRDT for situations when deriving the operations directly from user interactions is cumbersome.

Checkout how using a distributed time series database like InfluxDB can help keep track of application events from all multiple Rails processes in a centralized hub.
GraphQL multi-part request spec outlines a specification for multipart form requests in GraphQL. Jayden Seric, the author of the spec, has also authored two libraries apollo-upload-client and apollo-upload-server which makes it effortless to integrate file uploads in Apollo Server.
GridFS is a simple file system abstraction on top of MongoDB. This facilitates storage of large files (beyond BSON document size limit) in mongo database.
This post outlines the minimal integration required to save the files uploaded through the GraphQL API to GridFS.

It is fairly straightforward to add a GraphQL API powered by Apollo Server to a Next.js application through a koa middleware.
The abbreviated snippet below summarizes the setup along with the libraries involved:

One of the interesting aspects in Typescript is that it is easy to extract out individual types from composite types.

This post is intended to primarily benefit people coming from other, so called “modern” editors to Emacs. Emacs veterans are likely to find most of the tips here very elementary.
I have observed that many programmers habituated to newer editors have many implicit assumptions about editing workflows which simply don’t hold true within Emacs environment and this prevents them from being productive to the fullest extent.
This post primarily focusses on how getting familiar with the concept of
regions in Emacs can result in productive workflows. These concepts, coupled with a few extensions can enable much more pleasurable code-editing workflows not easily achievable in more prevalent “modern” editors.

Usage of C# inspired
Most of the times we
await on promises (typically returned from async functions), however, it is relatively less well known that
await works on arbitrary thenables. By thenables we mean any object with a
then function member.
This post covers this usage, and explores some scenarios where it can be interesting.
React refs are generally considered an anti-pattern as their usage typically encourages patterns which go against declarative compositon and top down flow of data.
This post explores a somewhat uncommon use case where refs can be used to expose layout slots in parent components to nested components.

I like F# and believe the author has done an amazing job evolving a functional language on the dot net platform but there are simply too many design choices in F# geared around C# compatibility and limitations of CLR being an object oriented language that when you switch to a different compilation target, these language aspects begin to look like bizarre warts.

While this post primarily compares Reason and TypeScript, much of what is outlined about TypeScript equally applies to flow as well.
