Rootkits replace parts of the operating system with an attacker’s code to hide malicious files and processes from the system's own security tools.

SQL injection vulnerabilities occur when developers incorrectly process user input, allowing attackers to sneak their own database commands into a web app.

Fuzzing is a testing technique that generates massive amounts of input to explore every possible path in a program to find crashes or bugs.

Deepfakes are counterfeit images, videos, or sounds generated by machine learning algorithms, often weaponized to psychologically influence a person's behavior.

Modern ransomware is sophisticated; it often encrypts a victim's files with a symmetric key, then encrypts that key with the hacker's public key for maximum protection.

Understanding the difference is key: MAC addresses identify who you are, IP addresses identify where you are, and ARP tables manage the mapping between them.

Many technology leaders making purchasing decisions have little teaching experience. This leads to schools adopting tools that may be inadequate for actual classroom needs.

Ethical hackers are vital security professionals who understand how to attack infrastructure to discover vulnerabilities before bad actors can exploit them.

Learning is a dynamic, ongoing process that is simultaneously biological and cultural. It isn't just for children; people continue to adapt to their environments and experiences from before birth through the entire life span.

Prior knowledge is a double-edged sword: it can reduce the mental effort needed for new tasks and facilitate learning. However, it can also lead to bias, causing learners to ignore new info that doesn't fit their existing mental frameworks

Much of what we know about the science of learning comes from "WEIRD" populations (Western, Educated, Industrialized, Rich, Democratic). We need more diverse research to ensure our understanding of learning applies to all human beings

Physical exercise isn't just for the body; it is beneficial for learning and cognition. Consistent exercise training in children is associated with improvements in reading comprehension, executive function, and mathematical computation.

It is neurobiologically impossible to think deeply about information for which you have no emotion. Emotions are a ubiquitous dimension of thought that steer our behavior and tell us what is important to remember.

A growth mindset—believing that intelligence can be acquired through hard work—leads learners to adopt mastery goals. Conversely, a fixed mindset often causes people to prioritize "looking good" over the actual effort required to learn

Culture is not an external influence but a central aspect of being human that coordinates the biological systems involved in learning. All learning is a social process shaped by and infused with a system of cultural meaning.

Schools must be careful not to let "educational technology titans" exploit students for profit or use them to test new products. Technology should serve the educational good, not techno-corporate ideals. #StudentPrivacy #EdTechEthics

The role of school IT managers is evolving. Beyond technical support, their core responsibility is to ensure that technology integration is never achieved at the cost of a student’s privacy or long-term interests. #ITLeadership #Ethics

Managing student data is like entrusting a sensitive family heirloom to a high-tech vault; while you want the vault to be secure and functional, you must constantly audit the operators to ensure they aren't secretly using your treasure for their own profit.
