The fundamentals of computer renew
Computers are electronic devices that can store, process, and retrieve data through both hardware and software. They provide benefits of speed, accuracy, and ability to work continuously. Computers take input through devices like keyboards, mice, microphones, and scanners. They process this input and provide output through monitors, printers, speakers, and other devices. Common computer components include the motherboard, CPU, memory, storage devices, power supply, and cooling fan. Software is divided into application software that enables specific tasks and system software that allows the computer to function, like operating systems.

Introduction of Cybersecurity with OSS at Code Europe 2024
I develop the Ruby programming language, RubyGems, and Bundler, which are package managers for Ruby. Today, I will introduce how to enhance the security of your application using open-source software (OSS) examples from Ruby and RubyGems.
The first topic is CVE (Common Vulnerabilities and Exposures). I have published CVEs many times. But what exactly is a CVE? I'll provide a basic understanding of CVEs and explain how to detect and handle vulnerabilities in OSS.
Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application.
I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.
Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

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.

- 2. Music Visual Art Extremely powerful Supercomputers are used to create modern 3-D models used in animation, games and military simulations The Graphic Arts industry has changed dramatically through computers as well
- 3. Computers are basically machines, made up of dif- ferent components - A modern computer consists of three major components: 1. Hardware ◦ Physical thing that you can touch or hold in your hand 2. Operating system ◦ Controls the hardware and enables users to interact with the computer (interface) 3. Applications ◦ Programs that allow you to do specialized tasks
- 4. Computers work through three stages: 1. Input 2. Processing 3. Output
- 5. The user initiates the action by doing something: ◦ Clicking the mouse ◦ Typing on the key board ◦ Touching the touch screen This is input
- 6. Components inside the system take over at that point - The operating system instructs the hardware how to handle your request At the heart of every computer is a central processing unit (CPU), usually a single, thin wafer of silicon and millions of tiny transistors The CPU handles the majority of the processing tasks and is the "brain" of the computer
- 7. Once the computer has processed the request, it shows you the result by changing what you see on the monitor or playing a sound through the speakers This is output
