Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Grafana Labs launches free incident management tool in Grafana Cloud
I dunno, I don't really mind self-hosting monitoring infrastructure. I basically pay for a website uptime checker to check that Alertmanager is working. If Alertmanager is down, obviously you have to manually check to see what else is down, but it doesn't fail open.
I wrote a little glue to make this straightforward for anyone else who uses Prometheus/Alertmanager: https://github.com/jrockway/alertmanager-status This ensures that the website check checks the health of the whole alerting pipeline; Prometheus has an always firing alert, Alertmanager is set to send that alert to alertmanager-status, and alertmanager-status starts failing its external health check if it isn't seeing that alert firing at the configured interval. If one of [Prometheus, Alertmanager, alertmanager-status] fails, then your website health check fails.

Slack’s Outage on January 4th 2021
It is quite awkward that the output of "working" and "completely broken" alerting systems have the same visible effect -- no alerts.
For Prometheus users, I wrote alertmanager-status to let a third-party "website up?" monitoring server check your alertmanager: https://github.com/jrockway/alertmanager-status
(I also wrote one of the main Google Fiber monitoring systems back when I was at Google. We spent quite a bit of time on monitoring monitoring, because whenever there was an actual incident people would ask us "is this real, or just the monitoring system being down?" Previous monitoring systems were flaky so people were kind of conditioned to ignore the improved system -- so we had to have a lot of dashboards to show them that there was really an ongoing issue.)

Ask HN: What Are You Working On?
Many things!
jsso2: Identity provider and authenticating proxy for your non-enterprise use cases. WebAuthn only, no passwords! I was tired of typing a password for things like Grafana and PGAdmin, and IP whitelisting my home Internet for things that didn't have built-in authentication. https://github.com/jrockway/jsso2
If I were starting from 0 today, I'd just use Dex and Envoy's built-in OAuth support. OAuth is overly complicated, requiring a bunch of configuration for each app, and a ton of code in each app... but it won. So use that.
jlog: I read a lot of log files in my day-to-day work and really like the idea of structured logs, but found them hard to read. jlog translates timestamps to my local time zone, lets me query them with jq, etc.: https://github.com/jrockway/json-logs Can't live without it, I use it many times every day, and have even convinced other people to use it without writing any documentation. (There are binary releases and a --help though!)
"kubectl jq": I wanted to play with writing Kubernetes plugins, so I made one that is just "kubectl get x -o json | jq". I use it pretty regularly, but the Kubernetes client machinery doesn't give you autocompletion for free, so it's pretty painful to use. When they fix that, I plan to write more kubernetes extensions (including one that invokes jlog on the logs, saving a pipe ;) https://github.com/jrockway/kubectl-jq
alertmanager-status: How do you know if your Prometheus/Alertmanager is working? If it breaks, it won't be sending you an alert, after all. https://github.com/jrockway/alertmanager-status
ekglue: The good parts of Istio, written by someone who read the xDS spec :P https://github.comjrockway/ekglue
For my day job, I work on Pachyderm Hub, which you should totally use if you want to run production-quality data science workloads (data provenance, reproducibility, etc.): https://hub.pachyderm.com/ I could write a lot about it, but basically... we have customers that want to use Pachyderm, but the complexity of Kubernetes stands in their way. How do you store logs? How do you monitor things? How do you give your coworkers access? We solve those problems by letting you click a button in a web UI. (As for why you'd want to use Pachyderm: https://www.pachyderm.com/use-cases/)

Protomaps – A free and open source map of the world
(.shp .gpkg ...) | ogr2ogr -> .geojson | tippecanoe -> .pmtiles
for OpenStreetMap data there's planetiler[4], and and openmaptiles[5] styles that work with Maplibre
with those combinations you've got a great start to something you can host for pennies on AWS S3+CloudFront or Cloudflare R2, with an open source data pipeline

Does anyone else have a solution for the satellite layer? I was using MapLibre [0] then needed direct-on-the-ground images which made me convert to Google Maps.

Use 3D map library with API key function of Amazon Location Service
When using the Amazon Location Service, I recommend MapLibre GL JS, which I introduced in my previous article, "Amazon Location Service and AWS Amplify to Use Various Map Library," but you can also use any map library you like, including iTowns this time. I hope you will choose the map library of your choice, including iTowns!

Using Lidar to map tree shadows
Your browser has a very powerful image decoder built into it, offloading the PNG decoding into Javascript is very resource hungry.
Using maplibre (or any map viewer) you can load blobs of image data out of a tiff and use `Image` or `Canvas` to render the data onto a map.
Its even easier if the tiffs are already Cloud optimized as they perfectly align to a 1-to-1 map tile and they don't need to be rescaled, you can then just render the images onto the map. eg here is a viewer that loads webps out of a 15GB tiff and uses Canvas to render them onto a map [1]
Unless you are trying to layer all your maps together, you also could stop reprojecting them into webmercator, or if your goal is to layer them, then storing them in webmercator would save a ton of user's compute time.
There are a bunch of us that talk web maping and imagery in the #maplibre and #imagery slack channels in OSMUS's slack [2]
