September 12, 2017: NTP

Wyatt Zacharias presented NTP, starting with a bit of theory and history of the protocol, and ending with practical information and a demo on setting up NTPD.

Wyatt has made his presentation slides, in PPTX and PDF format, available online.

RTFM: RCS Redux

Following up on his earlier presentation on Revision Control for SysAdmins, Adam Thompson presented this month's RTFM segment focused on RCS(1), the Revision Control System. Like other version control systems, RCS automates the storing, retrieval, logging, identification, and merging of revisions. This primer helped you manage your frequently-revised text, source code, programs, documentation, graphics, papers, and form letters. Adam demoed using RCS (including the ci(1), co(1), and rcsdiff(1) commands) to manage a shell script that might be modified by multiple maintainers.

October 10, 2017: VLAN Theory and Implementation

VLANs (Virtual Local Area Networks) allow you to partition a physical network at the data link layer, "creating the appearance and functionality of network traffic that is physically on a single network but acts as if it is split between separate networks." (Wikipedia) VLAN tagging (IEEE 802.1Q) allows traffic from multiple VLANs to travel between Ethernet switches over the same physical link.

In this presentation, Gilbert Detillieux introduced some of the basic concepts of VLAN setup, and showed how this can be implemented. Examples of implementation were given using Cisco IOS commands and typical Linux network interface configuration.

Gilbert has made (a Creative-Commons-licensed subset of) his presentation slides, in PPTX and PDF format, available online.

RTFM: Kid3

This month, Wyatt Zacharias presented and demonstrated Kid3, the KDE ID3 tag editor. Kid3 is available as open source, and as binaries for many popular platforms, including macOS and Windows. (The Windows implementation is what was shown.)

November 14, 2017: Linux Containers using LXD

LXD is a next-generation system container manager, which offers a user experience similar to virtual machines but using Linux containers instead. Kevin McGregor presented an introduction to basic Linux containers using LXD on Ubuntu.

RTFM: MacPorts

Adam Thompson presented and demonstrated MacPorts, one of the systems used for compiling, installing and upgrading command-line, X11 or Aqua based open-source software on the Mac operating system.

December 12, 2017: KeePass

Wyatt Zacharias gave a short demonstration of KeePass.

KeePass is a free open source password manager, which helps you to manage your passwords in a secure way. KeePass is fully open source (OSI certified). You can have a look at its full source and check for yourself whether the encryption algorithms are implemented correctly.

Round-table, Mingling and Munchies

As 2017 drew to a close, MUUG continued our recent tradition of turning the December meeting into more of a social event. We had the usual round-table session, followed by a mini-presentation, and then had some time for mingling, eating, and drinking. We also collected food and cash donations for Winnipeg Harvest.

January 9, 2018: Fusion Compositing Software

Tyhr Trubiak gave a basic introduction to the node-based digital compositing software: Blackmagic Fusion, which now has free versions available for Linux and macOS, as well as Windows. (Tyhr demoed the macOS version, since the Linux version kept crashing when his laptop was connected to the low-res data projector.)

Blackmagic Fusion is one of the many different software packages movie studios use to do visual effects in post-production on movies such as Thor, The Martian and Avengers: Age of Ultron. It is a GUI used to manipulate motion graphics.

RTFM: xargs (redux)

Adam Thompson presented an RTFM on xargs(1), a command line utility to forward output from one command to the command line of another.

February 13, 2018: iSCSI + S3 Cloud Backup

Wyatt Zacharias presented the AWS Storage Gateway with iSCSI block storage. The AWS Storage Gateway allows AWS S3 storage to be presented to hosts as native block devices using iSCSI. Wyatt demonstrated the setup of a new storage gateway and how to connect a new volume to the gateway with iSCSI, and also talked about the costs and technical limitations of the service.

RTFM: jmtpfs & simple-mtpfs Android USB

Trevor Cordes demonstrated how to transfer files to and from your Android device via USB cable using the MTP protocol and simple command line utilities. Cloud? We don't need no stinkin' cloud!

March 13, 2018: TBA

RTFM: ulimit

Gilbert Detillieux will present an RTFM on ulimit(1), as well as the csh/tcsh equivalent, limit(1). This is a shell built-in command for displaying and setting various per-process resource limits, using the setrlimit(2) system call.

Please note our new meeting location for this month: 1C16A Centenial Hall, University of Winnipeg, entrance on Ellice Ave. between Spence and Balmoral St. (Check out the UofW's maps for nearby parking locations.)
