Patterns for Defensive Programming in Rust | corrode Rust Consulting
corrode.dev/blog/defensive-programming[...] hard-learned patterns to write more defensive Rust code, learned throughout years of shipping Rust code to production. I’m not talking about design patterns here, but rather small idioms, which are rarely documented, but make a big difference in the overall code quality.

Collaborative Text Editing without CRDTs or OT - Matthew Weidner
mattweidner.com/2025/05/21/text-without-crdts.htmlThis blog post describes an alternative, straightforward approach to collaborative text editing, without Conflict-free Replicated Data Types (CRDTs) or Operational Transformation (OT). By making text editing flexible and easy to DIY, I hope that the approach will let you create rich collaborative apps that are challenging to build on top of a black-box CRDT/OT library.

Nick Appleton’s blog and stuff - Building a digital filter for use in synthesisers
www.appletonaudio.com/blog/2022/building-a-digital-filter-for-use-in-synthesisersThis is a tutorial on how to build a digital implementation of a 2nd-order, continuously-variable filter (i.e. one where you can change the parameters runtime) that has dynamic behaviour that mimics an analogue filter.

What I Wish Someone Told Me About Postgres
challahscript.com/what_i_wish_someone_told_me_about_postgresI want to try to catalog the bits that I wish someone had just told me before working with a Postgres database. Hopefully, this makes things easier for the next person going on a journey similar to mine.

Notes on Distributed Systems for Young Bloods – Something Similar
www.somethingsimilar.com/2013/01/14/notes-on-distributed-systems-for-young-bloodsBelow is a list of some lessons I’ve learned as a distributed systems engineer that are worth being told to a new engineer. Some are subtle, and some are surprising, but none are controversial. This list is for the new distributed systems engineer to guide their thinking about the field they are taking on. It’s not comprehensive, but it’s a good beginning.

Overloaded fields, type safety, and you
educatedguesswork.org/posts/text-type-safetyThe underlying problem we are facing here with all these examples is the same: having the same set of bits which can mean two different things and needing some way to distinguish those two meanings. Failure to do so leads to ambiguity at best and serious defects at worst. That's why you see so much emphasis in modern systems on type safety and on strict domain separation between different meanings.

Build your own SQS or Kafka with Postgres
blog.sequinstream.com/build-your-own-sqs-or-kafka-with-postgresWe're Sequin, an open source message stream built on Postgres. We think Sequin's cool, but you don't need to adopt the project to get started with streaming in Postgres. In fact, you can turn Postgres into a basic queue/stream pretty easily. Below, we share what we've learned so you
