• Show HN: SlideOps, slides from a repo that flag when they drift from the code

  I kept generating documentation with an agent, and weeks or months later it would quietly go stale. Updating it was the costly part: either let an agent re-scan the whole repo, or sit there trying to remember what changed. So I made the deck carry its own provenance. SlideOps turns a repo into a slide deck, and every claim in that deck records the file it came from, the exact line range, and a hash of those lines.... - Source: Hacker News / 1 day ago

  Maybe you could use something like this to make it real: > Building a Real-Time Concentration Tracker using MediaPipe and OpenCV > A simple AI project that measures focus and attention using your webcam — with Python, OpenCV, and MediaPipe. https://medium.com/@jiyasisdiya/building-a-real-time-concentration-tracker-using-mediapipe-and-opencv-2da7384ace24. - Source: Hacker News / 9 days ago

• Nebula Sans

  - Standard Broadcast "is owned by 44 total people, all of whom are creators" So it's fair to say there are creators with significant equity stakes in Nebula. It's NOT fair to assume that the 50% of revenue left after share is distributed evenly among all creators on the platform via an equity mechanism. Of course then there's Floatplane, which is entirely owned by LMG. At least a couple years ago they targeted "a... - Source: Hacker News / 6 days ago

• Data diffs: Algorithms for explaining what changed in a dataset (2022)

  > Make diff work on more than just SQLite. Another way of doing this that I've been wanting to do for a while is to implement the DIFF operator in Apache Calcite[0]. Using Calcite, DIFF could be implemented as rewrite rules to generate the appropriate SQL to be directly executed against the database or the DIFF operator can be implemented outside of the database (which the original paper shows is more efficient).... - Source: Hacker News / about 3 years ago

• How to manipulate SQL string programmatically?

  Use a SQL Parser like sqlglot or Apache Calcite to compile user's query into an AST. Source: over 3 years ago

• Parsing SQL

  One parser I think deserves a mention is the one from Apache Calcite[0]. Calcite does more than parsing, there are a number of users who pick up Calcite just for the parser. While the default parser attempts to adhere strictly to the SQL standard, of interest is also the Babel parser, which aims to be as permissive as possible in accepting different dialects of SQL. Disclaimer: I am on the PMC of Apache Calcite,... - Source: Hacker News / about 4 years ago

• Semantic Diff for SQL

  Apache Calcite can do this, though it's not a beginner-friendly task: https://calcite.apache.org/. - Source: Hacker News / about 4 years ago

• OctoSQL allows you to join data from different sources using SQL

  You should look at Apache Calcite[0]. Like OctoSQL, you can join data from different data sources. It's also relatively easy to add your own data sources ("adapters" in Calcite lingo) and rules to efficiently query those sources. Calcite already has adapters that do things like read from HTML tables over HTTP, files on your file system, running processes, etc. This is in addition to connecting to a bunch of... - Source: Hacker News / about 4 years ago
