Waves are never ending dynamic surfaces created by the action of wind on ocean surfaces. Waves are undulations of the surface layers of bodies of sea waters. Large bodies of water are almost constantly in motion. Ocean surface are never calm and smooth.They are uneven, irregular, rough and restless. Sea waves are defined as undulations of seawater characterized by unique features. Waves are moving energy patterns. They travel along the interface between ocean and the atmosphere.

How do ocean waves form?
“All waves are disturbances of a fluid medium through which energy is moved” (Davis,
1997). Ocean waves travel on the interface between oceans and the atmosphere, and are
produced most commonly by winds. As shown in Figure 1, the crest of a wave is its highest
point while the trough is the lowest. The height of the wave is the vertical distance between the
crest and the trough. The wavelength (λ) is the horizontal distance from crest to crest or from
trough to trough. The steepness is the ratio of its height to λ. When the steepness value reaches
0.143 (i.e., a ratio of 1:7), the crest of the wave breaks. Note that a steepness value less than
0.143 means a stable wave while one larger than 0.143 means an unstable breaking wave.
Figure 1. Key characteristics used to describe ocean waves.
Using Figure 1, please answer all of the following questions.
(1) What is the height of the illustrated wave?
(2) What is the wavelength?
(3) What is the steepness?
(4) Will the wave break given your answer to question (3)? Please briefly explain
your answer.
Using Figure 2, use two different colored pencils and sketch two waves:
Wave “A” has a height of 2 m and a wavelength of 10 m.
Wave “B” has a height of 4m and a wavelength of 6m.
For each wave, label the wavelength, wave height, crest, and trough.
Figure 2. A grid for drawing a wave.
(5) What is the steepness of wave A that you sketched?
(6) Will wave A break?
(7) What is the steepness of wave B that you sketched?
(8) Will wave B break?
When the interface between the oceans and the atmosphere is disturbed by a force, then
waves form. Most commonly that disturbing force is the friction of the wind moving across the
water. Once the wave has formed gravity acts against this disturbance, and attempts to restore the
water/atmosphere interface back to its flat-water position (i.e., a horizontal state). Hence, wind-
generated waves are sometimes referred to as gravity waves. As gravity pulls the crest of a wave
downward, momentum carries the water/atmosphere interface beyond the flat-water position to
form a trough. As a result, a buoy will appear to move up and down without being translated in
the direction that the waves appear to be moving. Such up and down motion will continue as
along as the wind is blowing. When the wind stops blowing, the water/atmosphere interface
returns to its normal flat-water state.
The period of a wave is the time it takes for one wavelength to pass a reference mark.
The periods for normal ocean waves range from a few seconds to about 15 seconds. Note that
this differs from wave celerity which is the speed at which a wave advances or propagates. Deep
water waves are waves that occur in water depth that is greater than one half their wavelength.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
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).
Speakers:
