Supporting the npmx Alpha Launch - AT Protocol The launch of npmx is an incredible showcase for how open source communities can build quickly on top of atproto.

It has been so exciting to see @npmx.dev come together over the past month. We're proud to offer our support β€” this project is just getting started. Congrats on the launch!

always-already-programming.md GitHub Gist: instantly share code, notes, and snippets.

”The distinction between programmer and user is reinforced and maintained by a tech industry that benefits from a population rendered computationally passive. If we accept and adopt the role of less agency, we then make it harder for ourselves to come into more agency.”

CIDs: What You Need to Know and Why, Part 1 A deep dive into Content Identifiers, the self-describing cryptographic fingerprints that form the foundation of ATProtocol’s data model.

I wrote a deep dive on CIDs, the self-describing cryptographic fingerprints behind every record, blob, commit, and Merkle tree node in ATProtocol. Part 1 covers the history, the encoding primitives, and the specific constraints ATProtocol applies.

atproto is cool because it is fundamentally pragmatic about what it means to be decentralised. decentralised where it matters, simple and scalable where it doesn’t

I installed NixOS for the ~5th time on my personal computer again after using it on servers for a while and this time I may just stick to it. I went the no-desktop path on the installer, added niri and noctalia-shell and it's been sooooo smooth

Let’s Build an Atmospheric Web The Atmospheric Web shows we don't have to accept the false choice of ownership vs. distribution

This is the most succinct version of a post I've been trying to write for two months. When I stop for just a sec to think about the possibilities of The Atmospheric web, I'm a little overwhelmed by how exciting it is. Come build it with us!

> To avoid such occurrences in future I would like to recommend you to change the value of "M out of N" for your alarm to something like "3 out of 3" as its currently set to "5 out of 5"

Or, you know, just actually alarm us at 5 out of 5?

Rant over.

Like what do you mean "CloudWatch looks for additonal datapoints"? Where? Why?

And how are people fine with having non-deterministic alerting. I might as well let an LLM decide if this metric is Alarm state. Or toss a coin.

> For example, if the alarm is having datapoints to alarm as 5 out of 5, it should look for 5 data points. But in the backend, CloudWatch looks for additional datapoints as well. In this case, suppose the alarm looks for additional 3 data points.

28.01.2026 14:08 πŸ‘ 0 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

> However, CloudWatch Alarm takes additional data points as well into consideration to avoid false alarms. Due to which, even though your metrics was not having datapoints for more than 5 minutes, the alarm still did not transition to "In Alarm" state.

> I would like to inform you that CloudWatch Alarm evaluates every minute irrespective of the time period you select, and the evaluation is based on the window of time defined by the Period and Evaluation Periods. In this case, you have kept the datapoints to alarm as 5 out of 5.

Now, we faced Cloudwatch shenanigans before where it "corrected" past data as new datapoints come in but this case was even more strange. So we decided to open a ticket with the support:

I have gotta rant about CloudWatch (AWS) for a moment - we have an alarm setup for 5 out of 5 datapoints where missing datapoints are treated as breaching. Now over the last days a case happened where this should have clearly triggered - we are missing 10 datapoints here. No alarm fired.

This feels true, estimating how long a task will take is the most useless thing we (as an industry) keep doing. It's pure theater and also so draining.

Don't you love it when managers declare multiple things as "the highest priority" and then wonder why not all of them get "enough attention" if tho they set the prio so high?
