SQLite was thought of as a toy for many years until we all realized it was actually nice to use a database as a library, even server-side. And yet...

It's a big dependency, despite what you think. In no universe is 150,000 lines of C code "lightweight".
Like with all SQL databases, you have an impedance mismatch: the way you store data in memory is completely different than the table structure a SQL database forces on you, leading to tons of glue code.
It's mutable, so it can't undo or time travel, and it can't read while a write is happening (even in WAL mode...reads can't happen during checkpointing!).

To solve these problems, I'm building a database called xitdb:

At only about 4,000 lines of code with no dependencies, xitdb is actually lightweight. You could reimplement it in another language pretty easily.
It exposes rich data structures rather than a SQL interface, so the API is very similar to the in-memory data structures you already use in your program.

A complete overview of PHP session handler life cycle

The purpose of this document is to provide a complete overview of the PHP session handler life cycle updated to version 7.0 or above. In particular, I want to emphasize what methods and in what order are called when the native PHP functions are used for session management.
I created this document because the information on the web and the official documentation are very superficial on this topic, in particular on what concerns the implementation of a safe and stable session handler.

	Originall From: Posted 2015-05-29 http://ubwg.net/b/full-list-of-ffmpeg-flags-and-options

	This is the complete list that’s outputted by ffmpeg when running ffmpeg -h full.

	usage: ffmpeg [options] [[infile options] -i infile]… {[outfile options] outfile}…

	Getting help:
	-h — print basic options
	-h long — print more options
	-h full — print all options (including all format and codec specific options, very long)
