The Post-TV Age?

Author: Shawn Powers | Files under syndicated

The most basic cable package from Charter (Spectrum?) costs me more than $70
per month, and that’s without any equipment other than a single cable
card. It’s very clear why people have been cutting the cord with cable
TV companies. But, what options exist? Do the alternatives
actually cost less? Are the alternatives as good? more>>

Unsupervised Learning

Author: Reuven M. Lerner | Files under syndicated

In my last few articles, I’ve looked into machine learning and
how you can build a model that describes the world in some way. All of
the examples I looked at were of “supervised learning”, meaning
that you loaded data that already had been categorized or classified in
some way, and then created a model that “learned” the ways
the inputs mapped to the outputs. more>>

Sysadmin 101: Automation

Author: Kyle Rankin | Files under syndicated

This is the second in a series of articles on systems administrator
fundamentals. These days, DevOps has made even the job title “systems
administrator” seem a bit archaic, much like the “systems

Incidents happen. Vulnerabilities happen. The quality of your response

In a previous article, “Provisioning Docker with Puppet”, in the December
2016 issue, I covered one of the ways
you can install the Docker service onto a new system with Puppet. By

Scissors, Paper or Rock?

Author: Dave Taylor | Files under syndicated

In this article, I’m going to tackle a children’s game that’s extraordinarily
complicated, with many variations, and the programming task is going to be quite
tricky. Just kidding! Rock Paper Scissors (or RPS, as it’s known) is
pretty darn easy to simulate because there aren’t really many variants or
possible outcomes.

The Current Phase of the Moon

Author: Dave Taylor | Files under syndicated

Ladies and gentlemen, we’ve left Mars. Well, at least I’m done with the
Martian lander from my past few articles. I hope you had chance to experiment with
it and find out that it’s not too easy to land a craft on any planet!

Mastering ATA over Ethernet

Author: Petros Koutoupis | Files under syndicated

At one point in time, when you wanted to attach an external block storage device to a
server, you mapped it as a Logical Unit (LU) across a Storage Area Network (SAN). In
the early days, you would do this over the Fibre Channel (FC) protocol. More recently,
iSCSI (SCSI over IP) has usurped FC in most data centers. more>>
