Some of the same people bounced around implementing it in different places, but they started from scratch each time. Some things to search for: JP Morgan Athena BofA Quartz Kirat Singh Mark Higgins

Full respect to this piece for including the phrase “the simplest possible thing”.

The subject does sometimes come up in my casual conversations, since Robin Milner was my first CS lecturer. He never actually spoke about type inference in my presence. He did teach me CCS (pi-calculus predecessor) a couple of years later,

Why? Bad management. Perhaps even bad leadership.

Amazing achievement. I did some work for Apricot at their Glenrothes factory around 1985-87. In my memory they went heavier on GEM than Windows. I never saw an Apricot running Windows prior to the PC-compatible models.

Matt Godbolt was saying recently that using tail-calls for an interpreter suits the branch predictor inside the cpu. Compared to a single big switch / computed jump.

The famous OSS database patterned after DynamoDB is https://cassandra.apache.org/ (Wondering if you never heard of it or if you don’t consider it commensurate).

> Mimir in version 3.0 needs Apache Kafka to work. I’d like to adjust this understanding. Kafka is the big new thing, but it’s optional. The previous way using gRPC still works. I work on Mimir and other things at Grafana Labs.

Span has a beginning and an end time. Event typically just has a time when it happened.

That is nice. But no detail after gen 5, so mostly historical interest.

You’re right, it’s not guaranteed. Also the hypervisor might lie to you - claiming a single NUMA node but actually crossing two on the VM host.

Whilst you’re right in broad strokes, I would observe that “the garbage-collector” is one of those tight loops. Single-threaded JavaScript is perhaps one of the best defences against NUMA, but anyone running a process on multiple cores and

Very detailed and accurate description. The author clearly knows way more than I do, but I would venture a few notes: 1. In the cloud, it can be difficult to know the NUMA characteristics of your VMs. AWS, Google, etc., do not publish it. I

Now you can’t detect overflow?

Then you would need 6 words to hold a 256-bit value instead of 5 in the OP, and consequently more instructions to add them.

I took a look at the code, to see how I would react as a reviewer. In the first file I opened, I got as far as here: https://github.com/Sleepful/mymail/blob/main/app/router/page... /&#

Windows 95 allowed long file names with arbitrary dots. The path length (including full folder path and the file name) was limited to 260 characters.

Agree that mark phase is the expensive bit. Disagree that it’s not worth reducing short-lived allocations. I spend a lot of time analyzing Go program performance, and reducing bytes allocated per second is always beneficial.
