From Monoliths to Microservices: Why Startups Should Avoid Premature Complexity

tl;dr: Node by default doesn’t implement the Happy Eyeballs algorithm for web requests, and therefore if a server has a broken IPv6 address that responds first, it will usually fail.

In this post, we’ll cover the basics of on-call scheduling, the different types of on-call schedules you can use and when each is most appropriate, best practices for managing on-call shifts, and all the mistakes people normally make along the way.

File sharing, url shortener and pastebin all in one place with QR code and curl support. Uses stream based cryptography and data processing that can handle gigabytes of data with fixed memory and cpu usage. It can run on anything including PaaS like repl.it or Render and is very easy to customize.

The idea comes from the need to manage huge amount of YAML files in a GitOps environment. Especially when using ArgoCD multi-source apps with some common values and some overrides.
The tool helps to compute the common base configuration among multiple YAML files and generate differences for each file, reducing the duplication of configuration values.
It also provides the ability to sort YAML content based on user-defined configuration.

Harper is an English grammar checker designed to be just right. I created it after years of dealing with the shortcomings of the competition.

Grammarly was too expensive and too overbearing. Its suggestions lacked context, and were often just plain wrong. Not to mention: it's a privacy nightmare. Everything you write with Grammarly is sent to their servers. Their privacy policy claims they don't sell the data, but that doesn't mean they don't use it to train large language models and god knows what else. Not only that, but the round-trip-time of the network request makes revising your work all the more tedious.

LanguageTool is great, if you have gigabytes of RAM to spare and are willing to download the ~16GB n-gram dataset. Besides the memory requirements, I found LanguageTool too slow: it would take several seconds to lint even a moderate-size document.

That's why I created Harper: it is the grammar checker that fits my needs. Not only does it take milliseconds to lint a document, take less than 1/50th of LanguageTool's memory footprint, but it is also completely private.

Harper is even small enough to load via WebAssembly.
