Consistent toolbox talks are critical for maintaining workplace safety, as they provide regular opportunities to address specific hazards and reinforce safe practices.
These brief, focused sessions ensure that safety is a continual conversation rather than a one-time event, which helps keep safety protocols fresh in employees' minds. Studies have shown that shorter, more frequent training sessions are more effective for retention and behavior change compared to longer, infrequent sessions.
Engaging workers regularly, toolbox talks promote a culture of safety, empower employees to voice concerns, and ultimately reduce the likelihood of accidents and injuries on site.
The traditional method of conducting safety talks with paper documents and lengthy meetings is not only time-consuming but also less effective. Manual tracking of attendance and compliance is prone to errors and inconsistencies, leading to gaps in safety communication and potential non-compliance with OSHA regulations. Switching to a digital solution like Safelyio offers significant advantages.
Safelyio automates the delivery and documentation of safety talks, ensuring consistency and accessibility. The microlearning approach breaks down complex safety protocols into manageable, bite-sized pieces, making it easier for employees to absorb and retain information.
This method minimizes disruptions to work schedules, eliminates the hassle of paperwork, and ensures that all safety communications are tracked and recorded accurately. Ultimately, using a digital platform like Safelyio enhances engagement, compliance, and overall safety performance on site. https://safelyio.com/

1. Introduction to
UNIX / Linux
CMSC 121 Introduction to UNIX
Much of the material in these slides was taken from
Dan Hood’s CMSC 121 Lecture Notes.
2. What is an Operating System?
The operating system (OS) is the program which starts up when
you turn on your computer and runs underneath all other
programs - without it nothing would happen at all.
In simple terms, an operating system is a manager. It manages all
the available resources on a computer, from the CPU, to
memory, to hard disk accesses.
Tasks the operating system must perform:
Control Hardware - The operating system controls all the parts of the
computer and attempts to get everything working together.
Run Applications - Another job the OS does is run application software.
This would include word processors, web browsers, games, etc...
Manage Data and Files - The OS makes it easy for you to organize your
computer. Through the OS you are able to do a number of things to data,
including copy, move, delete, and rename it. This makes it much easier to
find and organize what you have.
3. UNIX History
The UNIX operating system was born in the late 1960s. It
originally began as a one man project led by Ken Thompson of
Bell Labs, and has since grown to become the most widely used
operating system.
In the time since UNIX was first developed, it has gone through
many different generations and even mutations.
Some differ substantially from the original version, like Berkeley Software
Distribution (BSD) or Linux.
Others, still contain major portions that are based on the original source
code.
An interesting and rather up-to-date timeline of these variations
of UNIX can be found at
http://www.levenez.com/unix/history.html.
4. General Characteristics of UNIX as
an Operating System (OS)
Multi-user & Multi-tasking - most versions of UNIX are capable of allowing multiple
users to log onto the system, and have each run multiple tasks. This is standard for most
modern OSs.
Over 30 Years Old - UNIX is over 30 years old and it's popularity and use is still high.
Over these years, many variations have spawned off and many have died off, but most
modern UNIX systems can be traced back to the original versions. It has endured the test
of time. For reference, Windows at best is half as old (Windows 1.0 was released in the mid
80s, but it was not stable or very complete until the 3.x family, which was released in the
early 90s).
Large Number of Applications – there are an enormous amount of applications available
for UNIX operating systems. They range from commercial applications such as CAD,
Maya, WordPerfect, to many free applications.
Free Applications and Even a Free Operating System - of all of the applications
available under UNIX, many of them are free. The compilers and interpreters that we use
in most of the programming courses here at UMBC can be downloaded free of charge.
Most of the development that we do in programming courses is done under the Linux OS.
Less Resource Intensive - in general, most UNIX installations tend to be much less
demanding on system resources. In many cases, the old family computer that can barely run
Windows is more than sufficient to run the latest version of Linux.
Internet Development - Much of the backbone of the Internet is run by UNIX servers.
Many of the more general web servers run UNIX with the Apache web server - another
free application.
5. Parts of the UNIX OS
The Kernel - handles memory management, input and output requests, and
program scheduling. Technically speaking, the kernel is the OS. It provides the
basic software connection to the hardware. The kernel is very complex and
deals with the inner workings of these things, and is beyond the scope of this
course. The kernel is covered in detail in “Operating Systems.”
The Shell and Graphical User Interfaces (GUIs) - basic UNIX shells
provides a “command line” interface which allows the user to type in
commands. These commands are translated by the shell into something the
kernel can comprehend, and then executed by the kernel.
The Built-in System Utilities - are programs that allow a user to perform
tasks which involve complex actions. Utilities provide user interface functions
that are basic to an operating system, but which are too complex to be built
into the shell. Examples of utilities are programs that let us see the contents
of a directory, move & copy files, remove files, etc...
Application Software & Utilities – these are not part of the operating
system, per se. They are additional programs that are bundled with the OS
distribution, or available separately. These can range from additional or
different versions of basic utilities, to full scale commercial applications.
6. Flavors of UNIX
These can be grouped into two categories: Open Source and Proprietary
Proprietary: (redistribution and modification prohibited or restricted; not free)
Solaris - Access to a Solaris UNIX server (solaris.gl.umbc.edu) via SSH access.
IRIX - There are a couple of IRIX machines in the basement of the library, as well as server
access (irix.gl.umbc.edu) via SSH access.
Mac OS X - no access currently available at UMBC.
and many others...
Open Source: (source code is readily available and free to modify)
FreeBSD - no access currently available at UMBC.
Linux Distributions - access is available in the form of dual-boot PCs scattered throughout
the Engineering building. There are also several Linux servers (linux.gl.umbc.edu) through
which access is available.
RedHat (used by UMBC) and the Fedora Project (maintained by RedHat)
Mandrake
Debian
SuSE
Slackware
and many others...
As a side note, Linux is a open source UNIX-based OS that was originally developed in 1991 by
Linus Torvalds, a Finnish undergraduate student.
7. UNIX Interfaces
There are really 2 means of connecting to UNIX
computers here at UMBC:
You can be sitting in front of a dual-bootable PC that you
have booted into Linux and logged onto. All of your
commands are then being run locally on that computer.
When you logon in this manner you have a full GUI
environment.
You can connect remotely to one of the UNIX servers
(whether from home or at the labs). This is often how your
projects are suggested to be developed as they are graded on
those same servers. When you logon in this manner you have
a command line (or text based) environment. You can also
open up a command line on local lab machines as well.
8. Graphical User Interfaces (GUIs)
When you logon locally, you are presented with
graphical environment.
You start at a graphical login screen. You must enter
your username and password. You also the have the
option to choose from a couple session types. Mainly
you have the choice between Gnome and KDE.
Once you enter in your username and password, you
are then presented with a graphical environment that
looks like one of the following...
11. Command Line Interface
You also have access to some UNIX servers as well.
You can logon from virtually any computer that has internet
access whether it be Windows, Mac, or UNIX itself.
In this case you are communicating through a local
terminal to one of these remote servers.
All of the commands actually execute on the remote server.
It is also possible to open up graphical applications through
this window, but that requires a good bit more setup and
software. (Time permitting, we may cover how to do this.)
13. Linux vs. Windows
OS does not have to use a graphical interface.
The OS itself (the kernel) is incredibly small.
The GUI just another application (or set of applications) that can be
installed and run on top the existing text-based OS.
File system differences.
Windows typically uses FAT32 or NTFS file systems.
Linux typically uses the ext2 or ext3 file systems
In much larger research and university environments, where file access is
necessary across the network, something like Network File System (NFS)
or the Andrew File System (AFS) is used. We use AFS here on GL at
UMBC.
Windows lists all drives separately (A:,C:,D:, etc…), with “My Computer”
at the highest level.
UNIX starts its highest level at “/” and drives can be mounted anywhere
underneath it.
14. UMBC’s Computing Environment
You need a GL account username and password!
Since almost all UNIX systems are multi-user systems you will need to
have a logon name and password to authenticate yourself to the system.
At UMBC, when you signup for a GL account, you are given a username
and password, which is your means of logging on to any computer
system, be it UNIX, Windows or Mac.
Where is UNIX / Linux available?
There are many labs in the Engineering (ENG) building where there are
dual-bootable Windows and Linux PCs. You can simple reboot one of
these machines and select Linux as the operating system.
There are also a couple of other places across the campus where you can
sit directly in front of a UNIX computer. UMBC's Office of Information
Technology (OIT) maintains a list of the labs it maintains as well as
descriptions about the operating systems in those labs.
This list is online at
http://www.umbc.edu/oit/classroomtechnology/labs/lablocation.html.
15. Practical Tasks
Rebooting the computer into Linux on a dual-
boot PC.
Logging in.
Locking the screen.
Logging out.
The non-graphical terminal!
Press Ctrl-Alt-F2 then login
Be sure to logout with the command “logout”
Press Ctrl-Alt-F7 to get the GUI back.
16. If all else fails in Gnome or KDE
If your session seems to have froze up, you can
press ctrl-alt-backspace to restart the X
window server, in the process logging you out.
Note that by doing it this way, you risk losing
unsaved work.
17. What is X Window?
X window is the program that draws windows on the screen
under most GUI-based versions of UNIX. It is important to
note that the language that X windows speaks is completely
different from that of Microsoft Windows or Mac OS X.
Any X window system consists of 2 distinct parts - the X server
and 1 or more X clients.
The server controls the display directly, and is responsible for all
input/output via the keyboard, mouse or display.
The clients, on the other hand, do not access the screen directly - they
communicate with the server, which handles all input and output.
It is the clients which do the "real" computing work - running applications or
whatever.
The clients communicate with the server, causing the server to open one or
more windows to handle input and output for that client.
18. What’s the deal about the X Window
Server and Client?!
The X window server runs on the machine to which the monitor is
connected.
The clients may also run on this machine, communicating directly with the
server. On most workstations, this is the normal situation. However, X is a
networked window system, and it is possible for the client to run on a remote
machine, communicating with the server via some form of network.
It is possible to connect to one of the UMBC servers and launch graphical
applications from one of the UNIX servers.
This does require that an X window server is installed on the machine from which
you are connecting from. This is automatically running if you are running a GUI
UNIX system.
You can also install an X window server on top of Microsoft Windows, so that
you can open up windows locally that are talking to the server at UMBC. Like I
said earlier, this does require installing some software on the client side, and time
permitting we may talk about this later in the course.
19. What is a Desktop Manager?
Gnome and KDE are examples of desktop managers. Both of these look a
lot like Microsoft Windows.
They have the equivalent of a Start Menu, have an equivalent of Windows
Explorer, and have some sort of control panel.
The roll of the Desktop Manager is to provide you with the ability to manage
all of the details of your system that would otherwise require you to type in a
bunch of commands in a terminal window.
These details include managing your files, launching programs, configuring various
aspects of your system, etc.
It is also worthy to note that the desktop manager is optional. Many older
systems did not have a desktop manger that sat in-between the X server and
the Window manager.
20. What is a Window Manager?
The Window Manager is a program that manages the placement of Windows
on your system. The Window Manager makes it possible to move, resize, and
minimize the various programs running on your computer
KDE handles this functionality as well, whereas Gnome does not directly
provide this functionality, but rather relies on an independent window
manager to do it for us.
Think of the Window Manager as the framing around the windows as well as
all of the associated functionality that they provide.
For example, most all window managers can close, minimize, maximize & resize.
However most UNIX window managers add so much more in the way of
functionality. The decoration and customization of these windows under UNIX
tends to be much more flexible.
Many Window Managers also provide other functionality such as shading,
sticky/nonsticky, window history, and desktop and workspace manipulations.
21. Some Notes on X window, Desktop Managers &
Window Managers
Most UNIX systems can be installed without the GUI.
The GUI is just another application that runs on top of
the operating system.
There are many implementations of all three of these
components.
It is possible to mix and match implementation and versions
of these.
They need not be alike and need not be all by the same
organization.
This is quite a shift in paradigm from Microsoft and
Apple.
