So you want Git, Docker, and continuous integration for your documents?

The power of GitDocker, and continuous integration (CI) can be leveraged to makeTeX document compilation easy while keeping track of different variants and versions. On the top of these technologies, a flexible workflow can be developed to reflect successive changes in TeX documents in each PDF—versioned with a progressive number, document-v4.pdf, say.

This makes me think about every time I hear someone say all we need for legislation/court documents/legal documents is Github. The workflow described in this article would indeed solve any number of document issues, but I can’t imagine in my world really using this.

Netflix shows how they get a high level look at Linux in 60 seconds

In 60 seconds you can get a high level idea of system resource usage and running processes by running the following ten commands. Look for errors and saturation metrics, as they are both easy to interpret, and then resource utilization. Saturation is where a resource has more load than it can handle, and can be exposed either as the length of a request queue, or time spent waiting.

uptime
dmesg | tail
vmstat 1
mpstat -P ALL 1
pidstat 1
iostat -xz 1
free -m
sar -n DEV 1
sar -n TCP,ETCP 1

Some of these

commands

  require the sysstat package installed. The metrics these commands expose will help you complete some of the USE Method: a methodology for locating performance bottlenecks. This involves checking utilization, saturation, and error metrics for all resources (CPUs, memory, disks, e.t.c.). Also pay attention to when you have checked and exonerated a resource, as by process of elimination this narrows the targets to study, and directs any follow on investigation.

Lots of good info here, though I suspect many sys admins already run through most of this once they land on a box.
