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.

Refactoring Toward Configurability
For this example, we will use JSON files to encode the application's behavior and query it using JSONPath.
- Ask HN: What is something you built but never marketed?
-
Running Jenkins on PR in Azure DevOps
As shown above in order to access the root element of a JSON payload we can create variable (data) and assign the $ (using Json Path convention) in the expression tab.
-
what's the best way to search all child objects in java?
You certainly could implement a recursive traversal, as /u/raevnos suggested, but it might be easier to use something like JsonPath to do it for you.
-
Query with jsonpath
If you work with REST interfaces for any amount of time, you'll run into "json path". You can extract and manipulate the json received with an API call.
-
How would experienced devs handle checking JSON objects for specific property condition?
Look into JSONPath and its one Java implementation.
-
Like JQ, but for HTML
is anyone else using the https://github.com/json-path/JsonPath over the jq route?
I hope we standardize on some jq query language, like we have with a base set of SQL syntax
-
Which JSON parsers do not require me to duplicate the document model?
I use JsonPath for this. This fits my use case of picking apart JSON responses from APIs in Cucumber tests, which is based on textual descriptions and I'm not using Java classes for the mapping.

Serverless Complex Event Processing with Apache Flink
flatMap — A Map function (can be of Rich type if need be) that extracts data from the input event which is a stringified JSON object. Of the three flapMaps, two of them extract & parse the relevant data into a defined model (the data modelling is based on POJO — plain old java object classes.) using JsonPath, the third flapMap is a RichCoFlatMapFunction that determines after correlating events from the two sources whether it should be forwarded to the sink or not.
-
Traversing nested data-structures in various languages
JSONPath confers pretty much the same concept onto JSON too with much the same syntax. There are JPath implementations for most languages now.

How to troubleshoot yaml parsing error "did not find expected key"?
Install jq and yq, and wrap your commands with | yq -y ..

Memes are all cool and all. But this is your daily remaining that 10000! =
Confusingly there is another project called yq that does exactly what you're suggesting and it's a preprocessor that converts yaml to json and then used jq. https://github.com/kislyuk/yq

Yq is a portable yq: command-line YAML, JSON, XML, CSV and properties processor
I personally find the yq tool from https://github.com/kislyuk/yq much more useful: it has all the same options and formats as `jq` (as it's really a wrapper around jq). Rather than the `yq` in the OP here where only partial functionality exists.

Scraping weather info
XML data from the API can be parsed and filtered with xq. There may be multiple ways to get it; first try the yq toolset which includes it.

Show HN: Xq – command-line XML and HTML beautifier and content extractor
There is also yq [1], which attempts the same for yaml, toml and xml. (And confusingly also contains a binary named "xq" for querying xml, however with a different syntax)
