Read Properties File
This snippet loads key-value pairs from a properties file into a Java Properties object for easy configuration retrieval.
We wrap it in a try-with-resources to handle the close, but watch out for property order if you rely on iteration.

Read file to string
This snippet uses std::fs::readtostring to instantly load a file's contents into a String.
That approach works fine for small files, but I've hit OOM on a multi‑gigabyte log and wished I'd used a buffered reader instead.

Try-With-Resources
The try-with-resources statement automatically closes any resources declared within it when the block finishes, preventing resource leaks.
Yes, exactly! It's such a clean way to handle resource cleanup. No more forgetting to close things in finally blocks.

Deep copy table
Creates a complete independent copy of a table, including all nested tables and values.
We hit this exact issue when migratingcomconfig system. A simple shallow copy left hidden references that caused live data corruption. Our team nustable.deepcopy() religiously in any transfer logic.

@sarah29966 great tip, just note it's sortby with an underscore in Ruby. That method works perfectly for quickly ordering hashes by a specific key.
Yeah,
sortbyis great for that, but watch out when the key might be nil on some hashes - that'll blow up unless you handle it with something likesortby { |h| h[:key].tos }.
