General Unix "Few tools are more indispensable to my work than Unix. Manipulating data into different formats, performing transformations, and conducting exploratory data analysis (EDA) is the lingua franca of data science.1 The coffers of Unix hold many simple tools, which by themselves are powerful, but when chained together facilitate complex data manipulations. Unix's use of functional composition eliminates much of the tedious boilerplate of I/0 and text parsing found in scripting languages. This design creates a simple and succinct interface for manipulating data and a foundation upon which custom tools can be built. Although languages like R and Python are invaluable for data analysis, I find Unix to be superior in many scenarios for quick and simple data cleaning, idea prototyping, and understanding data. This post is about how I use Unix for EDA."

It's a wonderfully sensible convention set to be discarded by the systemd folks

...what? Systemd will change how logging is done? Please tell me that's not the case.

To be fair, they let you run your old logger in parallel -- all you have to do is change you tried-and-true tools to use their new super-duper interface:

Are they not merciful?

More than that - not only are they not stopping you from running a traditional logger if you want one, they're providing fancy tools designed specifically for running complex queries over the binary log format.

In short, they're actually making things easier to parse logging data.

Ok, not as horrible as I initially thought. syslog is a pretty shitty logging system, that I can agree with.
I would have liked to see the example use more structured data though and not a freeform "user blah logged in" message.
Don't see why this should be a feature of systemd though and not a standalone system. The arguments for forcing systemd on us are pretty bogus. Tightly integrated? Yeah, right. Good thing we don't have message passing technologies these days or something.
Also, what's with being so defensive about UUId's? (I don't mind them, it's just fascinating how big a deal it seems to be)

As a big fan of Upstart (and daemontools/runit/etc) I think it's about time the abomination known as SysV init is abandoned (along with runlevels) and in that respect Systemd is a step forward. I kinda wish it didn't try to weasel in everywhere though. (A GNOME dependency? WTF?)
