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.

Open source tools and standards to lookup known files
Shameless plug: I wrote a small poc module to use hashlookup's bloom filter in yara (https://github.com/VirusTotal/yara). The idea is to easily discard files that are known to be safe and so to avoid launching thousands of yara rules on a file for nothing. One can also use it to keep track of some files that meet certain conditions for instance. The module can store any string in these filters so I see a lot of useful use-cases for this little thingy :)

Ask HN: Regex on a File or Stream
Maybe some other PCRE-compatible implementation offers streaming. For instance, https://www.intel.com/content/www/us/en/developer/articles/t... says it has this feature, but of course given who it's from it may be tied to a single brand of CPU.

Stop deploying web application firewalls
I think of WAFs as an extra safety net. Defense in depth.
The author complained about the performance cost of WAFs in general, but not all WAFs have be structured like ModSecurity. They could for example be based on something like https://github.com/intel/hyperscan and perf is at a very different level.

Show HN: Unblob – extraction suite for 30+ file formats
We are using hyperscan [3] instead of grepping byte sequences with Python, which is orders of magnitudes faster. It can also handle 4Gb+ files because of this which binwalk cannot.
It's used for a year now in production and it's way more precise and faster than binwalk. We are getting less false-positives too, and even if unblob fails to extract everything, we still get meaningful information out of firmwares, where binwalk just failed with no output previously.
