Jobs in electronics are in high demand and well paid in almost every country! Building electronic products is incredibly rewarding, whether you do it professionally or just as a hobby. There is just something different and exciting about designing something physical that can be hold in one’s hand and that interacts with the outside world, and today it has become incredibly easy to get started thanks to cheap development boards such as the Arduino and Raspberry Pi, combined with the right knowledge. Differently than what happens in other disciplines, knowledge of Electronics does not become obsolete, but it is always current as it is intimately connected to physics and to the fundamental laws of nature. Hence, while new components and chips might come along every year, the fundamental principles of Electronics always stay the same. WHAT'S DIFFERENT ABOUT THIS COURSE? While most of the material and courses available online tend to be high-level and focused on applications (for instance, it shows students how to connect components on a breadboard to create a circuit), the goal of this course is to explain the fundamental concepts of Electricity and Electronics, to allow you to fully understand how circuits work. Every topic is addressed starting from the first principles of the underlying physics and fundamental laws, and only later the acquired knowledge is used to explain how to design more complex circuits for different applications. WHAT WILL YOU LEARN? • Fundamental concepts of Electricity (Current, Energy, Voltage, Power) • Most important electronic components (Resistor, Capacitors, Diodes, etc) • The main laws governing currents and voltages in circuits (Ohm’s law, Kirchhoff’s laws, etc) • Interface with Microcontrollers (coming soon) ANY PREREQUISITE? This is an introductory course about the theory of Electricity and Electronics, so no previous knowledge is required. To get the best out of the lessons, students should be comfortable with some basic arithmetic as I will often write and solve equations, in particular when analyzing simple circuits. Understanding a bit of physics can help too, but it is not required. Most importantly, no special hardware or software is required.

Workload Manager Validation for SQL Server
This is a self-paced lab that takes place in the Google Cloud console. Workload Manager for SQL Agent.
The Agentic AI Security Masterclass
This masterclass examines how security must evolve when AI systems are no longer passive tools, but autonomous actors that plan, decide, and execute actions in real-world environments. Agentic AI systems introduce a fundamentally different risk profile. Failures often emerge without exploits, without malicious intent, and without clear signals. Systems can behave correctly at a technical level while becoming unsafe, untrustworthy, or misaligned over time. This course is designed to address that gap. Modern agentic systems plan their own actions, select tools, maintain memory, coordinate with other agents, and act with varying degrees of autonomy. These capabilities introduce risks that do not fit neatly into traditional cybersecurity models. Failures often emerge gradually, look like success at first, and involve no obvious attacker at all. This course is built to address that reality. Across twelve deeply structured modules, learners are guided through the full lifecycle of agentic systems from a security perspective. The course begins by establishing a clear understanding of what makes agents fundamentally different from earlier AI and software systems, then progressively examines how goals drift, how tools are misused, how memory and context become liabilities, and how autonomy quietly expands beyond what was originally intended. Rather than focusing on isolated vulnerabilities, the course treats agentic AI as a socio-technical system. It examines how agents interact with infrastructure, data, humans, and each other, and how risk emerges at those boundaries. Learners explore real-world inspired scenarios involving goal hijacking, reward hacking, cross-agent failure loops, credential misuse, memory poisoning, manipulation of human trust, and emergent rogue behavior. Security is approached as an architectural and behavioral discipline, not a checklist. The course emphasizes designing systems that remain safe even when agents reason incorrectly, receive ambiguous input, or operate under uncertainty. Topics include secure agent architecture, identity and access controls for non-human actors, sandboxed execution, supply chain trust, constraint enforcement, behavioral monitoring, kill switches, observability, governance, and long-term resilience. Hands-on labs are integrated throughout the course to reinforce learning through experience.

Computer forensics is the application of investigation and analysis techniques to gather and preserve evidence from a particular computing device in a way that is suitable for presentation in a court of law. The goal of computer forensics is to perform a structured investigation and maintain a documented chain of evidence to find out exactly what happened on a computing device and who was responsible for it. Computer forensics -- which is sometimes referred to as computer forensic science essentially is data recovery with legal compliance guidelines to make the information admissible in legal proceedings. The terms digital forensics and cyber forensics are often used as synonyms for computer forensics. Digital forensics starts with the collection of information in a way that maintains its integrity. Investigators then analyze the data or system to determine if it was changed, how it was changed and who made the changes. The use of computer forensics isn't always tied to a crime. The forensic process is also used as part of data recovery processes to gather data from a crashed server, failed drive, reformatted operating system (OS) or other situation where a system has unexpectedly stopped working. Why is computer forensics important? In the civil and criminal justice system, computer forensics helps ensure the integrity of digital evidence presented in court cases. As computers and other data-collecting devices are used more frequently in every aspect of life, digital evidence and the forensic process used to collect, preserve and investigate it -- has become more important in solving crimes and other legal issues.
