Emotional intelligence was first defined scientifically in 1990 by Mayer and Salovey, building on prior concepts. Goleman later proposed it involves five traits that determine one's EQ. Emotional intelligence involves self and social awareness and management. It is debated whether EQ can be accurately measured, though tests do exist to assess specific skills or provide an overall assessment. While EQ may help predict some life outcomes, it does not determine success on its own, and high IQ individuals like Einstein had low EQ without hindrance. EQ is significant for social and workplace interactions but is not a sole predictor of life outcomes and has limitations as a concept.
This document discusses databases and the evolution from flat files to relational databases. It covers:
1) The limitations of flat files including data duplication, separation of data across files, fixed queries, and proliferation of application programs.
2) The introduction of hierarchical and network databases to try to overcome limitations but these still led to inconsistent and redundant data.
3) An introduction to relational databases which overcome limitations by allowing each record to be of fixed length and each field to contain a single data item. This addresses issues with variable length records in previous approaches.
The document discusses the functions and purposes of translators in computing. It describes:
1) Interpreters and compilers translate programs from high-level languages to machine code. Compilers translate the entire program at once, while interpreters translate instructions one at a time as the program runs.
2) Translation from high-level languages to machine code involves multiple stages including lexical analysis, syntax analysis, code generation, and optimization.
3) Linkers and loaders are used to combine separately compiled modules into a complete executable program by resolving addresses and linking the modules together.
This document discusses common network environments, connectivity, and security issues. It describes how LANs and WANs are organized using different topologies and transmission mediums. It then explains key network components like switches, routers, bridges, and modems - how they connect different types of networks and segments. Finally, it discusses common network environments like the Internet, intranets, and extranets as well as technologies that enable them such as hypertext links, URLs, domain names, and HTML.
The operating system must manage hardware resources, provide an interface between users/software and hardware, and provide services like data security. It schedules programs to make best use of the processor when programs are performing input/output tasks. It uses interrupts to change the normal order of program execution in response to events like I/O device signals. Scheduling aims to maximize system usage, be fair to all programs, and prioritize more important programs when needed.
The document discusses computer architecture and the fetch-execute cycle. It describes the Von Neumann architecture, which uses a single processor that follows a linear sequence of fetching, decoding, and executing instructions. It then explains the fetch-execute cycle in more detail with the steps involved. Finally, it discusses parallel processor systems that can split up the fetching, decoding, and executing stages to improve efficiency.
The document discusses techniques for developing computer systems, including structured systems analysis and design method (SSADM) and data flow diagrams (DFDs). It provides details on the stages of SSADM and the symbols and steps used to develop DFDs. An example of a hotel reservation and payment system is presented as a DFD to illustrate the technique. Project management is also discussed, with an example of building a bungalow broken down into tasks, durations, and dependencies shown in a graph.
The document discusses different ways of representing numerical data in computing systems, including:
1) Binary representation, which converts decimal numbers to binary by repeatedly dividing by column headings and tracking the remainders as 1s and 0s.
2) Negative numbers can be represented using sign-and-magnitude or two's complement methods.
3) Other number systems like octal and hexadecimal are also discussed which use different column headings but the same representation principles.
4) Floating point representation separates a real number into a mantissa and exponent to store fractional numbers more efficiently in binary.
The document discusses how data and databases are valuable to organizations. It provides examples of how stock control systems and sales data can be used to automatically reorder stock. Banks also find customer data valuable for assessing loan risks. Modern communication allows sharing of data worldwide through value added network services and databases. Standards are needed for sharing data accurately between different systems. Computers now aid various forms of communication like voice mail, e-commerce, and video conferencing. The internet allows global communication and advertising. IT training must be continually updated as technology changes, which is altering many work patterns and jobs.
This document discusses different programming paradigms including procedural, object-oriented, and declarative paradigms. It provides examples of code using these paradigms. Specifically, it shows an assembly language program that adds two numbers, a C++ program that calculates the area of a rectangle, and Prolog queries to retrieve information from a database about people's genders and family relationships. It also discusses how parameters are used to pass values to functions in Visual Basic.
This document discusses real-time systems and simulation. It defines a real-time system as one that can react quickly enough to input data to affect the real world. Real-time applications include airline booking systems and nuclear reactor controls. Sensors measure physical quantities and transmit data to processors, while actuators accept signals from processors and initiate physical movements. Simulations allow computers to model real-world systems and scenarios through calculations, enabling testing without real-world risks or costs. Simulations have limitations in predicting truly random or complex human events. Parallel processing is needed for simulations involving vast data, complex relationships, and immense calculations.
This document is an exam for an Advanced Subsidiary Level computing exam. It contains 9 questions testing knowledge of topics like memory addressing, data structures, networks, and software development processes.

Chris Jones, Director of Product Management at BrainChip , presents the “Temporal Event Neural Networks: A More Efficient Alternative to the Transformer” tutorial at the May 2024 Embedded Vision Summit.
The expansion of AI services necessitates enhanced computational capabilities on edge devices. Temporal Event Neural Networks (TENNs), developed by BrainChip, represent a novel and highly efficient state-space network. TENNs demonstrate exceptional proficiency in handling multi-dimensional streaming data, facilitating advancements in object detection, action recognition, speech enhancement and language model/sequence generation. Through the utilization of polynomial-based continuous convolutions, TENNs streamline models, expedite training processes and significantly diminish memory requirements, achieving notable reductions of up to 50x in parameters and 5,000x in energy consumption compared to prevailing methodologies like transformers.
Integration with BrainChip’s Akida neuromorphic hardware IP further enhances TENNs’ capabilities, enabling the realization of highly capable, portable and passively cooled edge devices. This presentation delves into the technical innovations underlying TENNs, presents real-world benchmarks, and elucidates how this cutting-edge approach is positioned to revolutionize edge AI across diverse applications.
[OReilly Superstream] Occupy the Space: A grassroots guide to engineering (an...Jason Yip
The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction.

Power Grid Model
The global energy transition is placing new and unprecedented demands on Distribution System Operators (DSOs). Alongside upgrades to grid capacity, processes such as digitization, capacity optimization, and congestion management are becoming vital for delivering reliable services.
Power Grid Model is an open source project from Linux Foundation Energy and provides a calculation engine that is increasingly essential for DSOs. It offers a standards-based foundation enabling real-time power systems analysis, simulations of electrical power grids, and sophisticated what-if analysis. In addition, it enables in-depth studies and analysis of the electrical power grid’s behavior and performance. This comprehensive model incorporates essential factors such as power generation capacity, electrical losses, voltage levels, power flows, and system stability.
Power Grid Model is currently being applied in a wide variety of use cases, including grid planning, expansion, reliability, and congestion studies. It can also help in analyzing the impact of renewable energy integration, assessing the effects of disturbances or faults, and developing strategies for grid control and optimization.
What to expect
For the upcoming meetup we are organizing, we have an exciting lineup of activities planned:
-Insightful presentations covering two practical applications of the Power Grid Model.
-An update on the latest advancements in Power Grid -Model technology during the first and second quarters of 2024.
-An interactive brainstorming session to discuss and propose new feature requests.
-An opportunity to connect with fellow Power Grid Model enthusiasts and users.

Bram Verhoef, Head of Machine Learning at Axelera AI, presents the “How Axelera AI Uses Digital Compute-in-memory to Deliver Fast and Energy-efficient Computer Vision” tutorial at the May 2024 Embedded Vision Summit.
As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector. This shows that advanced computer vision can be accessible and efficient, even at the very edge of our technological ecosystem.
