Cerebro creativo goel, 2014
This article discusses creativity in the context of designing artifacts like architecture. It proposes that understanding design creativity requires understanding the array of symbol systems that designers use, ranging from vague sketches to precise technical drawings. Vague symbols support associative thinking to broaden problem-solving, while precise symbols support logical thinking to deepen problem-solving. This leads to a dual-mechanism model of design problem-solving using both associative and logical thinking. There is also evidence that the right prefrontal cortex supports vague, ambiguous thinking for broadening ideas, while the left prefrontal cortex supports precise thinking for deepening ideas. Successful design requires balancing these two types of thinking.
Pierre et gilles
Pierre Commoy and Gilles Blanchard are French artists who began collaborating in 1979. They are known for hand-painting photographs in vibrant colors. Their technique involves carefully staging photo shoots with costumes and props they have collected, then painting embellishments over the photographs. One of their most famous works is Autoportrait 78, which depicts two men entwined in a blue background surrounded by flowers. The painting conveys a sense of peaceful bonding through its bright colors and the subjects' expressions. Critics praise the unique combination of photography and painting in Pierre et Gilles' works, though some find the subject matter or compositions too busy at times.

New downtown,Singapore
The document discusses plans for new downtown development in Singapore to address issues of limited land, overcrowding, and inadequate infrastructure. The development will transform underutilized waterfront areas into vibrant mixed-use neighborhoods with new housing, offices, retail, and attractions. Major projects include Marina Bay Sands, Gardens by the Bay, Marina One, and expansion of the Greater Southern Waterfront area. Critics question how the plans will balance land uses and physical scales, integrate with the historical city, and accommodate a range of income groups. The extensive redevelopment aims to sustain Singapore's position as a global economic hub while creating livable, environmentally friendly neighborhoods.
Internal ceed
This document discusses an internal CEEDERSHIP program in AIESEC Poland to spread knowledge of their Global Talent Placement (GTP) program between local committees.

A presentation I made. If you think its good do hit the like button.
also tell me if I should make more. It is about generation of computers and how the computers have evolved over a period of time.
generations of computers.pdf
The modern computer took its shape with the arrival of your time. It had been around 16th century when the evolution of the computer started. The initial computer faced many changes, obviously for the betterment. It continuously improved itself in terms of speed, accuracy, size, and price to urge the form of the fashionable day computer. This long period is often conveniently divided into the subsequent phases called computer generations:
First Generation Computers (1940-1956)
Second Generation Computers (1956-1963)
Third Generation Computers (1964-1971)
Fourth Generation Computers (1971-Present)
Fifth Generation Computers (Present and Beyond)
Before there are graphing calculators, spreadsheets, and computer algebra systems, mathematicians and inventors searched for solutions to ease the burden of calculation.
Below are the 8 mechanical calculators before modern computers were invented.
1. Abacus (ca. 2700 BC)
2. Pascal’s Calculator (1652)
3. Stepped Reckoner (1694)
4. Arithmometer (1820)
5. Comptometer (1887) and Comptograph (1889)
6. The Difference Engine (1822)
7. Analytical Engine (1834)
8. The Millionaire (1893)
First Generation Computers: Vacuum Tubes (1940-1956)
The technology behind the primary generation computers was a fragile glass device, which was called vacuum tubes. These computers were very heavy and really large in size. These weren’t very reliable and programming on them was a really tedious task as they used low-level programming language and used no OS. First-generation computers were used for calculation, storage, and control purpose. They were too bulky and large that they needed a full room and consume rot of electricity.
Main first generation computers are:
ENIAC: Electronic Numerical Integrator and Computer, built by J. Presper Eckert and John V. Mauchly was a general-purpose computer. It had been very heavy, large, and contained 18,000 vacuum tubes.
EDVAC: Electronic Discrete Variable Automatic Computer was designed by von Neumann. It could store data also as instruction and thus the speed was enhanced.
UNIVAC: Universal Automatic Computer was developed in 1952 by Eckert and Mauchly.
Main characteristics of first generation computers are:
Main electronic component Vacuum tube.
Programming language Machine language.
Main memory Magnetic tapes and magnetic drums.
Input/output devices Paper tape and punched cards.
Speed and size Very slow and very large in size (often taking up entire room).
Examples of the first generation IBM 650, IBM 701, ENIAC, UNIVAC1, etc.
Second Generation Computers: Transistors (1956-1963)
Second-generation computers used the technology of transistors rather than bulky vacuum tubes. Another feature was the core storage. A transistor may be a device composed of semiconductor material that amplifies a sign or opens or closes a circuit.
Transistors were invented in Bell Labs. The use of transistors made it possible to perform powerfully and with due speed.
Concept & generation of computers
The document summarizes the history and generations of computers. It discusses 5 generations from the 1st generation which used vacuum tubes and were very large, to the current 4th generation which are smaller and use integrated circuits. The 5th generation still in development aims to develop devices that can understand natural language and are capable of learning. Each generation saw improvements in size, speed, reliability and programming capabilities due to advances in hardware technologies.
Computer Generations
The document discusses the five generations of computers from the 1940s to present. Each generation saw improvements in technology, from vacuum tubes in first generation computers to integrated circuits and microprocessors today. Key developments included increased processing speed and memory capacity, smaller size and power consumption, multi-user systems, high-level programming languages, personal computers, and networking capabilities like the internet.
Different generations of computers
The document discusses the five generations of computers from the first to fifth generation. The first generation used vacuum tubes and stored data using acoustic delay lines. The second generation used transistors for CPUs and magnetic cores for memory. The third generation saw the development of integrated circuits which further reduced the size of computers. The fourth generation used microprocessors and microcomputers became common. The fifth generation uses artificial intelligence techniques.

-Power systems data, focusing on grid data, inclusive of transmission and distribution networks, generation, intergrid power flows, and market settlement data
Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

GNSS spoofing via SDR (Criptored Talks 2024)
In the realm of cybersecurity, offensive security practices act as a critical shield. By simulating real-world attacks in a controlled environment, these techniques expose vulnerabilities before malicious actors can exploit them. This proactive approach allows manufacturers to identify and fix weaknesses, significantly enhancing system security.
This presentation delves into the development of a system designed to mimic Galileo's Open Service signal using software-defined radio (SDR) technology. We'll begin with a foundational overview of both Global Navigation Satellite Systems (GNSS) and the intricacies of digital signal processing.
The presentation culminates in a live demonstration. We'll showcase the manipulation of Galileo's Open Service pilot signal, simulating an attack on various software and hardware systems. This practical demonstration serves to highlight the potential consequences of unaddressed vulnerabilities, emphasizing the importance of offensive security practices in safeguarding critical infrastructure.

We will talk about system monitoring from a few different angles. We will start by covering the basics, then discuss SLOs, how to define them, and why understanding the business well is crucial for success in this exercise.
Lee Barnes - Path to Becoming an Effective Test Automation Engineer.pdf
So… you want to become a Test Automation Engineer (or hire and develop one)? While there’s quite a bit of information available about important technical and tool skills to master, there’s not enough discussion around the path to becoming an effective Test Automation Engineer that knows how to add VALUE. In my experience this had led to a proliferation of engineers who are proficient with tools and building frameworks but have skill and knowledge gaps, especially in software testing, that reduce the value they deliver with test automation.
In this talk, Lee will share his lessons learned from over 30 years of working with, and mentoring, hundreds of Test Automation Engineers. Whether you’re looking to get started in test automation or just want to improve your trade, this talk will give you a solid foundation and roadmap for ensuring your test automation efforts continuously add value. This talk is equally valuable for both aspiring Test Automation Engineers and those managing them! All attendees will take away a set of key foundational knowledge and a high-level learning path for leveling up test automation skills and ensuring they add value to their organizations.
