Newton's Laws describe the motion of objects. Newton's First Law states that objects at rest stay at rest and objects in motion stay in motion with the same speed and direction unless acted upon by an unbalanced force. Newton's Second Law states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, and inversely proportional to the object's mass. Newton's Third Law states that for every action, there is an equal and opposite reaction.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

2. Newton’s First Law
Newton’s First Law: An object at rest or an
object in motion at constant speed will
remain at rest or at constant speed in the
absence of a resultant force.
A glass is placed on a board and the board is
jerked quickly to the right. The glass tends to
remain at rest while the board is removed.
3. Newton’s First Law (Cont.)
Newton’s First Law: An object at rest or an
object in motion at constant speed will
remain at rest or at constant speed in the
absence of a resultant force.
Assume glass and board move together at
constant speed. If the board stops suddenly,
the glass tends to maintain its constant speed.
4. Inertia
• Newton's first law is often referred to as the
law of inertia.
• Inertia is the resistance or unwillingness of an
object to accelerate (speed up, slow down, or
change directions).
• The more mass an object has, the harder it is
to accelerate. Thus, more mass equals more
inertia.
5. Understanding the First Law
(a) The driver is forced to move forward. An
object at rest tends to remain at rest.
Discuss what the driver
experiences when a car
accelerates from rest and
then applies the brakes.
(b) Driver must resist the forward motion as
brakes are applied. A moving object tends
to remain in motion.
6. Newton’s Second Law
• Second Law: Whenever a resultant force
acts on an object, it produces an
acceleration that is directly proportional to
the force and inversely proportional to the
mass.

amaF
Force Units: Newton’s or N
7. Acceleration and Force
Pushing a cart with twice the force
produces twice the acceleration. Three
times the force triples the acceleration.
8. Newton: The Unit of Force
One newton is the force required to give an
acceleration of 1 m/s2 to a mass of 1 kg.
F (N) = m (kg) a (m/s2)
What resultant force will give a 3 kg mass an
acceleration of 4 m/s2?
F = 12 N
F = ?

11. Example A 54-g tennis ball is in contact with the racket for a
distance of 40 cm as it leaves with a velocity of 48 m/s. What
is the average force on the ball?
Given: vo = 0; vf = 48 m/s x = 0.40 m;
m = 0.0540 kg; a = ?
First, draw sketch and list
given quantities:
Given: vo = 0; vf = 48 m/s
x = 40 cm; m = 54 g
a = ?

13. Weight and Mass
• Weight is the force an object applies as a
result of gravity pulling it downward. It is
directed downward and it varies with gravity.
• Mass is a universal constant which is a
measure of the matter that makes up an
object. It is always constant regardless of
location
mgW
maFBecause weight is a force created
by the downward acceleration of
gravity, we can make this
substitution.
14. Weight and Mass: Examples
What is the weight of a 10-kg block?
9.8 m/s2 W
m10 kg
W = mg = (10 kg)(9.8 m/s2)
W = 98 N
The weight of an object is the
force it causes as a result of
gravity.
The weight of an object is also referred to as the force of gravity
15. Always Remember!!
In Physics, the use of Newton’s second law
and many other applications makes it
absolutely necessary to distinguish between
mass and weight. Use the correct units!
Metric SI units: Mass is in kg; weight is in N.
Always give preference to the SI units.
Pounds should never be used!!!
16. Example A resultant force of 40 N gives a block an
acceleration of 8 m/s2. What is the weight of the
block near the surface of the Earth?
W=?
F = 40 Na
8 m/s2
To find weight, we must first
find the mass of the block:
Now find weight of a
5-kg mass on earth.
W = mg
= (5 kg)(9.8 m/s2)
W = 49.0 N

17. Newton’s Third Law

must be an equal and opposite reaction
force. Forces occur in pairs.

18. Action and Reaction Forces
Use the words by and on to study
action/reaction forces below as they
relate to the hand and the bar:
The action force is exerted by
the _____ on the _____.
The reaction force is exerted
by the _____ on the _____.bar

19. m= 1 kg
Forces
If a bar of gold that has a mass of 1 kg is sitting at
rest on a table, what forces are acting on it and to
what magnitude?
FN= 9.8 N
The normal force of
an object pushes up
with a force equal to
the bar’s downward
force. Because both
forces are
present, the bar
remains at
equilibrium.
Gravity acts on the
object in the
downward direction.
However, because the
bar is not moving
downward, there must
be another force
counteracting it.
Fg= 9.8 N
20. Free-body Diagrams
• A free body diagram is a diagram that shows
all of the forces present on a given object.
• When drawing a free body diagram, objects
are always represented as points or dots and
forces are drawn as arrows pointing away
from the object.
• For now the only forces we will consider are
gravity, tension, normal, applied, and friction.
21. Free-body Diagrams
• Gravitational Force: This is the only force that
will always be present and will always point
straight down.
• Tension Force: This type of force is caused by
a rope, chain, string, etc. and goes in the
direction of the rope, chain, string, etc.
• Normal Force: This type of force is present
when the object is in contact with a surface.
It always points perpendicular to the surface.
22. Free-body Diagrams
• Applied Force: This type of force is used when
an outside agent is acting on the object such
as a person.
• Frictional Force: This type of force is the result
of two surfaces being drug across each
other, creating friction. It always points in the
direction opposite of the movement.
The size of the arrow should be proportional to the
size of the force. Larger forces should have larger
arrows!!!
24. Example A cart and driver have a mass of 120 kg. What
force F is required to give an acceleration of 6 m/s2
with no friction?
1. Read problem and draw a sketch.
2. Draw a free body diagram and label forces.
Diagram for Cart:

3. Choose x-axis along motion and indicate the
right direction as positive (+).

25. Example What force F is required to give an
acceleration of 6 m/s2?
Fy = 0; FN - Fg = 0
The normal force FN
is equal to weight Fg
Fx = max; Fa = ma
Fa = (120 kg)(6 m/s2)
Fa = 720 N
m = 120 kg
4. Write Newton's Law equation for both axes.
ay = 0

26. Example What is the tension FT in the rope below if
the block accelerates upward at 4 m/s2? (Draw

Fx = m ax = 0
Fy = m ay = m a
FT- Fg = m a
Fg=mg = (10 kg)(9.8 m/s) = 98 N
m a= (10 kg)(4 m/s) = 40 N
FT - 98 N = 40 N FT = 138 N
27. Example Find the acceleration of the blocks if there is no
friction on the surfaces.
