I’ve spent years failing to produce a blog post length text on structured programming, so here’s a quick gloss:
Structured programming is the basis of all our programming practice, and everyone has complete misapprehensions about what it means in ways that don’t hold up to 10 seconds of scrutiny.

Anyway just thought of this because I saw a post saying you shouldn't use continue. We will continue to superficially misunderstand the point of "structured programming" until the end of time.

Found this tonight and it's a really solid read on the Go runtime. Definitely a long post but it's got a lot of useful info in it.
Learned a lot about things that I haven't really dug into before from it.

@gmahovlic.bsky.social What is the status of ULX4M? I am interested in this board, but it is long time since the last update on crowdsupply. Looks good with an ECP5 board with SERDES for PCIe.

With time to spare, I recommend following up with Sagas by Garcia-Molina and Salem.
You’ll quickly see how both build on similar mechanics, but with a key difference: Transactions operate at the platform level, while sagas operate at the application level

The thread below seemed to resonate!
For developers building new types of applications on Kafka, I think Kafka Streams is the best available technology. This is largely due to its embedded form factor: developers want to build apps, they don't want to manage clusters! (1/4)

I'm finding two divergent interpretations of 'stream processing':
For some, it's primarily 'better' data processing, eg. streaming is better than batch.
For others, it's a way to build applications and experiences that wouldn't be possible in a non event-driven fashion.
Does that resonate?

Why is std::pin::Pin so weird?
Values of certain Rust types need to be pinned, which prevents them from moving in memory. This is expressed via the std::pin::Pin wrapper type and is typically encountered in the form of a functio…

Embarrassing as it is, I cannot but be a techno-optimist. Can you imagine that we will collect sun beams & wind gusts and use them to gather heat from the air outside & to make our pots cook themselves with magnets, so that we might no longer burn the forests to the ground to warm our hearths?

Wrote a post walking you through building a super minimal in-memory storage engine for MySQL/MariaDB in 218 lines of C++.
And took time again to reflect on the limitations of custom storage engines and how MySQL compares to Postgres internally here.
