This document describes the development of a wearable technology product to analyze a baseball batter's swing. Sensors are placed in the batter's shoes to measure foot pressure, tilt, and pivot throughout the swing. The data is sent to a mobile app via a microcontroller for real-time feedback and analysis. The goal is to help batters and coaches identify areas for improvement by comparing movements to successful hitters. Additional sensors and connectivity could further enhance swing analysis capabilities.

The document compares the Apple Watch and LG Watch Urbane. The Apple Watch has a brighter display, customizable home screen navigation via the Digital Crown, and integrated health and workout tracking apps. However, it starts at the same $349 price point as the LG Watch Urbane, which lacks an ambient light sensor and is not as focused on fitness, but does have heart rate monitoring and notification cards. Overall, the Apple Watch seems more full-featured while the LG Watch Urbane is more basic, but they are priced equally at $349.

Troubleshooting assistance is available through the college's Adaptive Technology Specialist.
Using the mouse
Douglas Engelbart at the Stanford Research Institute invented the first computer mouse prototype in 1963 with assistance from his colleague Bill English. The mouse allows users to perform actions like pointing, clicking, right-clicking, double-clicking, and dragging on a computer using hand movements that control the mouse pointer on the screen. Different mouse actions allow users to select, move, and manipulate items.
computer
A computer is a programmable device that can perform arithmetic and logical operations automatically. It consists of a monitor, keyboard, mouse, CPU, speakers and UPS. The CPU contains the processor, like the latest Intel i7, which allows it to run programs and applications like Windows. Computers have evolved from early calculators to modern laptops that are compact and portable. Now computers are ubiquitous and integral to many aspects of modern life.

The document discusses the history and types of computer mice. It begins by defining a mouse as a device that allows users to control the cursor and select objects on screen. The first mouse was invented in 1968 and used a rolling ball to detect movement. Over time, mice evolved to use optical sensors instead of balls and became wireless. Different types of mice include optical, wireless, trackball, and vertical mice. The mouse design has changed significantly over time to be smaller and more ergonomic while improving motion detection.

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.
Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

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.
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).
