*TOPIC: Intro to Hadoop for big data.*
*Presenter: Steven Lembark*
Steven Lembark will give us an introduction to Hadoop. It's a
framework/tool to deal with huge and dissimilar data spread across multiple
machines. It grew out of Google's early efforts to organize what they
gathered "surfing the net".
Apache Hadoop is an open source, Java-based software platform/ecosystem
that manages processing & storage for big data apps. It handles datasets
ranging in size from gigabytes to petabytes of data. They can be fed and
analyzed by many distributed computers over many distributed disk farms to
be read and analyzed by many dispersed computers requesting data.
Hadoop is an ecosystem of open source components that fundamentally changes
the way enterprises store, process, and analyze data.
In the infancy of The Internet, there was the quest to "find stuff".
“Search engines” were needed. Google, AltaVista, Yahoo, AskJeeves,...all
had ideas how to do it.
Inspired by their MapReduce, a programming model that divides an
application into small fractions to run on different nodes, Google started
Hadoop in 2002 while working on the Apache Nutch.
In 2003, Hadoop was in the academic paper describing the "Google File
System". In 2006, the Apache
<https://www.google.com/url?q=https://www.google.com/search?sca_esv%3D597118…>
Software Foundation
<https://www.google.com/url?q=https://www.google.com/search?sca_esv%3D597118…>
released
an open src version.
Altho now there are other tools used for such large data (ex Apache Hive ·
Apache Spark · Amazon EMR · Azure Data Lake Storage · IBM Analytics Engine
· Hortonworks Data Platform · Apache Pig, Clarissa,....) there are still
those depending on Hadoop, including Netflix.
*So, Steven will tell us…*
An Overview of the Apache Hadoop Ecosystem:
There is stuff that's growing on your data warehouse hard disks. In the
beginning was Hadoop, and was, well, Google's. And everyone tried it.
But as Google dropped the approach as ineffective lots of other folks had
found ways to make pieces of it work, added new pieces to it, and out of
the ashes of single-purpose Hadoop grew the Apache Hadoop
ecosystem.
Today this includes a variety of software for intake, querying, mapping SQL
to key:value stores, and a few other cute tricks.
This talk will look at the pieces of this ecosystem, a bit about how they
fit together, and how they can be used for Really Truly HUUUUUUGE data
processing.

BASE Topic: History of the Shell
Presenter: Ed Howland <https://www.sluug.org/bio/Ed_Howland>
Do you ever feel the raw power thrumming between your fingers when you open your terminal?
Are you amazed by the fact that most of our entire digital world is held together by the Duck Tape called shell scripts?
Did the concept of the World Wide Web spring forth in whole cloth out of the grey cells of Sir Berners-Lee?
These answers and more will be explored in this month's thrilling episode of the Base session on Wednesday night's meeting of the St. Louis Unix User's Group. Let Ed be your guide on this fascinating journey through time as we explore the history of the Shell! Starting with the Dawn B.T.E. ( Before the Epoch ) and the arrival of the Big Blue monolith, and continuing through the co-evolution of hardware, operating systems and user interfaces before arriving at "The One True Way": The Shell. Don't miss the notable landmarks on this fast-paced trek such as JCL, CICS, GECOS, MULTICS and, of course, UNICS.
Something more advanced, detailed, important, new, profound, significant, timely or useful.
MAIN Topic: Systemd Timers Better Than cron
Presenter: Sean Twiehaus <https://www.sluug.org/bio/Sean_Twiehaus>
In this presentation Sean will show you three features that make Systemd Timers better than crontabs. These features help to understand which jobs will run when, reduce the amount of shell code the administrator must maintain, and allow modification of vendor jobs while avoiding conflict.
Here are the three features (subject to change)
Detailed View of all Jobs on a System
When each job will run next in a human-readable time format
Less shell code required
Built-In Randomization Timers
Build in conditions like ACPower
Overridable without conflicts
If a Systemd Timer is installed by a package, such as Unattended Upgrades, it will have a default time that it runs. With Systemd Timers you can override the default time without having conflicts if the package maintainers update the timer.
(Bonus if time permits) Centralized Logging
Systemd services log to the journal

You do not have to have a microphone and webcamera to participate. You
can just chat, listen and watch using a Chrome based browser. Suggest
that you clear browser cache and cookies before starting session.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
RECOMMENDED CLIENT TESTING:
We will open the remote session by about 6:00 PM, Central Daylight Time.
Join early to test your microphone, screen, sound and video sharing.
Instead of using a browser, it has been recommended to use the official
Jitsi appimage clients. Reportedly using these clients consistently have
better results, with fewer connectivity, sound or video issues.
Highly recommended to use version 2023.10.0 (or newer, when available):
Appimage MS Windows, macOS and Linux client releases...
> https://github.com/jitsi/jitsi-meet-electron/
Mobile app clients for Apple or Android...
> https://jitsi.org/downloads
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
JITSI MEET HANDBOOK USER-GUIDE NOW AVAILABLE:
> https://jitsi.github.io/handbook/docs/user-guide/
It list supported browser versions and considerable guidance for new
and experienced users alike.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
JOINING THIS ONLINE SESSION:
6:00pm Start testing of controls, hearing, screen sharing and speaking.
During this half hour test period others may be able to help you.
Currently known Firefox compatibility bugs may cause problems for others
already in Jitsi sessions.
Joining without ear buds, earphones or headset may result in a feedback
loop with a builtin laptop microphone. Using at-least earbuds is highly
recommended. Ethernet is always better than WiFi connectivity.
If you do not make the effort and take the time to get your connection
working correctly, you may be very disruptive. Try dropping your
connection and rejoin. That sometimes fixes issues. But, do so slowly,
as granting access to your microphone and camera too quickly is the
current main problem. Also, there are often sound settings in different
browsers that may need to be changed.
======================================================================
WHEN YOU ENTER THIS ONLINE SESSION:
6:00pm Join early.
Join early if you want to test your camera, microphone (sound), or
screen sharing. You might be muted on entry.
Moving your mouse pointer to bottom of your display will bring up
select-able controls. Or, you can enter "?" to display a list of all
keyboard shortcuts.
Use letter C on keyboard to toggle Chat room, which will allow you to
set your name.
Use letter M on keyboard to toggle (mute or unMute) your Microphone.
Use letter V on keyboard to toggle your camera Video.
The meeting will be recorded for quality control.
Do NOT remain named as Fellow Jitster. Set your identity to show first
name and last name. Instead of full last name you could just follow
first name with an initial. We prefer that you use your full last name.
If you select three vertical dots (more actions) displayed in lower
right hand corner, select Settings, then under Profile "Set your display
name". You can ignore the "Set your gravatar email block". Assistance
with controls, hearing, screen sharing and speaking ends with start
of the meeting.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
6:30pm Start of meeting.
Anybody joining after 6:30pm that experiences issues with controls,
hearing, screen sharing or speaking should only use chat room to ask
questions or make comments.
All might be muted at this point. You may have to unmute yourself
in order to speak. You can ask questions and make comments in chat room.
Annoying disruptions may cause you to be kicked off the session.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
ORDER OF EVENTS:
First some simple introductions, administrative minutia, announcements,
and then you can Call For Help during our Questions and Answers period.
Hold you questions until after start of meeting.
Sometimes we may watch a video or have a slide show presentation,
after which there will be general discussions that usually lead to
additional topics.
Sometimes, there can be a live demonstration of a Linux distribution
(distro) installation, updating, changes, features and applications.
$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
TOPICS:
We often hold a Hardware and Software Configuration Workshop when
nothing else more interesting comes up, or when there is no other
event or activity scheduled.
The workshop is where we usually configure, examine, fix, install,
repair, and troubleshoot difficult hardware and software configuration
problems for Linux newcomers. Problems with other operating systems and
hardware are also frequently fixed.
