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.

anyone have experience writing data to parquet files? Is there a better alternative for storing large amounts of financial tick data?

Oracle DB support in Benthos
github.com/segmentio/parquet-go -> it's early days but his library is looking very promising for building applications that read or write parquet data, which was a major pain point not that long ago

ArcticDB: A Database for Observability
Finally seeing Apache Parquet and Apache Arrow used with Go efficiently and effectively!
Great job. Looking forward to exploring this more in the Prometheus and CNCF Ecosystem.
The underneath library used (https://github.com/segmentio/parquet-go) looks amazing too!

The Awk Programming Language, Second Edition
TIL: GoAWK [1] - A POSIX-compliant AWK interpreter written in Go, with CSV support.

Anyone else doing compiler work in Golang?
Another nice project that I have used from time to time (and a very good source for insight) is the awk interpreter written in go https://github.com/benhoyt/goawk

Tool to interact with CSV
No, I want exactly the opposite - it should be a , b,c as a single string field containing a literal comma, and c. For example, https://github.com/benhoyt/goawk has csv support. https://github.com/benhoyt/goawk/blob/master/docs/csv.md - more info.

Why does awk parse '1&&x=1' as '1&&(x=1)' not '(1&&x)=1' when '&&' is high precedence than '='?
I've had a go at solving this in this PR -- feedback welcome. I don't love it, but oh well, it solves the problem at hand. Your comment pointed me in the right direction, thanks again.

Looking for programming languages created with Go
There are quite a few re-implementations of scripting languages like Lua in Go. I've written an AWK interpreter in Go.

Oracle DB support in Benthos
github.com/benhoyt/goawk -> this library lets you embed an AWK runtime in your applications, very easy to use and useful for enabling some powerful scripting in things you build

Brian Kernighan adds Unicode support to Awk (May, 2022)
Yes, that's right. With my simplistic UTF-8-based implementation it turned length() -- for example -- from O(1) to O(N), turning O(N) algorithms which use length() into O(N^2). See this issue: https://github.com/benhoyt/goawk/issues/93
Similar with substr() and other string functions, which when operating as bytes are O(1), but become O(N) when trying to count the number of codepoints as UTF-8.
GNU Gawk has a fancier approach, which stores strings as UTF-8 as long as it can, but converts to UTF-32 if it needs to (eg: the string is non-ASCII and you call substr).
It looks like Brian Kernighan's code has the same issue with length() and substr(). I'm going to try to email him about this, as I think it's kind of a performance blocker.

Ask HN: Is having a Personal blog/brand worth it for you?
I'm not sure if it was via my personal website or just my GitHub profile, but I got my current job at Canonical due to the CTO there reaching out about my GoAWK project (https://github.com/benhoyt/goawk). I get regular recruitment emails because I have my CV/resume online: most of them are very low-effort, but 1 in 20 or something are interesting emails where the recruiter has actually looked at my website and will tailor it personally. I also just enjoy technical writing, and get joy out of sharing it on HN. So it's "worth it" for me.
