Collision Detection In this lesson, you will learn about: Using the concept of collision detection in games.

What is Collision Detection? Now let’s talk about collision detection in games. In general, collision detection is about determining the intersection of two moving objects. Collision detection in games takes place in the following steps: ,[object Object]

Checking whether a collision occurred between the identified objects or not.,[object Object]

Hit the Target – The Game You use the logic of collision detection to detect the collision between the turtle and the target. The game ends as soon as the two objects collide. The game involves two objects: the turtle and the target. The player has to make the turtle hit the target by entering the correct angle and the distance. Now that you have understood the concept of collision detection in games, let’s make a game that uses the logic of collision detection.

Hit the Target – How to Play It’s time to play the game! Steps to play the game: ,[object Object]

Enter the distance that the turtle needs to cover to hit the target.

Click the ‘Hit’ button to hit the target.

Click the ‘Reset’ button to reset the position of the target.,[object Object]

Fwdays

Direct losses from downtime in 1 minute = $5-$10 thousand dollars. Reputation is priceless. As part of the talk, we will consider the architectural strategies necessary for the development of highly loaded fintech solutions. We will focus on using queues and streaming to efficiently work and manage large amounts of data in real-time and to minimize latency. We will focus special attention on the architectural patterns used in the design of the fintech system, microservices and event-driven architecture, which ensure scalability, fault tolerance, and consistency of the entire system.

Dandelion Hashtable: beyond billion requests per second on a commodity server

Antonios Katsarakis

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).

DanBrown980551

This LF Energy webinar took place June 20, 2024. It featured: -Alex Thornton, LF Energy -Hallie Cramer, Google -Daniel Roesler, UtilityAPI -Henry Richardson, WattTime In response to the urgency and scale required to effectively address climate change, open source solutions offer significant potential for driving innovation and progress. Currently, there is a growing demand for standardization and interoperability in energy data and modeling. Open source standards and specifications within the energy sector can also alleviate challenges associated with data fragmentation, transparency, and accessibility. At the same time, it is crucial to consider privacy and security concerns throughout the development of open source platforms. This webinar will delve into the motivations behind establishing LF Energy’s Carbon Data Specification Consortium. It will provide an overview of the draft specifications and the ongoing progress made by the respective working groups. Three primary specifications will be discussed: -Discovery and client registration, emphasizing transparent processes and secure and private access -Customer data, centering around customer tariffs, bills, energy usage, and full consumption disclosure -Power systems data, focusing on grid data, inclusive of transmission and distribution networks, generation, intergrid power flows, and market settlement data

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...

Alex Pruden

Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security. Paper Link: https://eprint.iacr.org/2024/257

GNSS spoofing via SDR (Criptored Talks 2024)

Javier Junquera

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.

Apps Break Data

Ivo Velitchkov

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?

4.3 collision detection

1. Microsoft® Small Basic Collision Detection Estimated time to complete this lesson: 1 hour

2. Collision Detection In this lesson, you will learn about: Using the concept of collision detection in games.

5. Hit the Target – The Game You use the logic of collision detection to detect the collision between the turtle and the target. The game ends as soon as the two objects collide. The game involves two objects: the turtle and the target. The player has to make the turtle hit the target by entering the correct angle and the distance. Now that you have understood the concept of collision detection in games, let’s make a game that uses the logic of collision detection.

7. Enter the distance that the turtle needs to cover to hit the target.

8. Click the ‘Hit’ button to hit the target.

10. Next, use the Controls object to add a click button and text box and set the size of control buttons.

11. Use the Shapes object to add an image of the shape, and to move and animate the shape and set its opacity level.

12.

13. It’s Time to Apply Your Learning… Using the concept of collision detection, create a game that involves two objects: a bucket and apples. The apples fall randomly from the top of the screen. The player tries to catch the apples in the bucket. The game runs for 30 seconds. Include a score board to display the total number of apples caught by the player in 30 seconds. Your game should look somewhat like the following.
