Sound is a form of energy that travels in waves from a vibrating object. It travels faster through solids than liquids or gases. The ear takes in sound waves and converts them into signals to the brain. Sound waves have alternating high and low pressure areas that move outward in all directions. The pitch of a sound depends on its frequency, with higher pitches having shorter wavelengths and higher frequencies. Musical instruments can change pitch by altering the length or thickness of the vibrating material.

Essential things that should always be in your carEason Chan
A driver can bail out of a lot of sticky situations if he plans ahead. More often than not, things go south on you when you think nothing could go wrong. So it pays to hope for the best and plan for the worst, especially on the road. Here are some things that should always be kept in your car for all those just in case moments.
What happens when the digital tools and platforms we make and use for communication and entertainment are hijacked for terrorism, violence against the vulnerable and nefarious transactions? What role do designers and developers play? Are we complicit as creators of these technologies and products? Should we police them or fight back? As Portfolio Lead for Northern Lab, Northern Trust's internal innovation startup focused on client and partner experience, Antonio will share a mix of provocative scenarios torn from today's headlines and compelling stories where activism and technology facilitated peace—and war.
As a call-to-action for designers and developers to engage in projects capable of transformational change, he'll explore the question: How might technology foster new experiences to better accelerate social activism and make the world a smarter, safer place?
we hear many type of sound from various sources like humans, birds, bells, machines, vehicles, televisions, radios, etc. Sound is a form of energy which produces a sensation of hearing in our ears.
The presentation which increases your knowledge about sound.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

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).

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!

2. Overview
• The Facts of Sound
• The Ear and Sound
• Sound Vocabulary
• Musical Instruments and
Sound
3. The Facts
Sound …
1. Is a form of energy produced &
transmitted by vibrating matter
2. Travels in waves
3. Travels more quickly through solids than
liquids or gases
4. The Ear
• Sound is carried to our ears through
vibrating air molecules.
• Our ears take in sound waves & turn them
into signals that go to our brains.
• Sound waves move through 3 parts of the
ear; outer ear, middle ear, & inner ear.
Middle Ear
6. Sound Waves
- Alternating areas of high & low pressure
in the air
- ALL sound is carried through matter as
sound waves
- Sound waves move out in ALL directions
from a vibrating object
7. Wavelength & Frequency
- Wavelength is the distance between one
part of a wave and the same part of the
next wave
- Frequency is the number of waves moving
past a point in one second
8. Pitch
• A measure of how high or low a sound is
• Pitch depends on the frequency of a sound wave
• For example,
- Low pitch
- Low frequency
- Longer wavelength
- High pitch
- High frequency
- Shorter wavelength
9. Sonar
- An instrument that uses reflected sound
waves to find underwater objects
- For example,
Animals use sonar or echo location to find their
prey; these sounds have such a high pitch or
frequency that the human ear cannot hear
Humans use sonar
to locate or map
objects
10. Sound and Instruments
- Instruments can be played at different
pitches by changing lengths of different
parts.
- For example,
- Another way to make different pitches is
to change the thickness of the material
that vibrates.
- For example,
A trombone’s mute absorbs
some of the sound waves
produced, thus producing a
softer note when played.
