The Case Logic
Structure

@ The case logic structure is made up of several or
many sets of instructions, only one of which will
be selected by the user and executed by the
programmer.

@ The form of the case logic structure is the
following:

CASE OF VARIABLE
= constant 1:
actions for VARIABLE = constant 1
= constant 2:
actions for VARIABLE = constant 2
= constant 3:
actions for VARIABLE = constant 3

The document discusses static single assignment (SSA) form, a program representation where each variable is assigned only once. SSA form makes data flow analysis simpler by explicitly representing value definitions and merges. The transformation to SSA form involves inserting φ-functions to merge multiple reaching definitions at control flow merges, and renaming variables. Different approaches to placing φ-functions are minimal, Briggs-minimal, and pruned SSA. Briggs-minimal may add φ-functions that pruned SSA omits if they are dead.

9 processing arraysRheigh Henley Calderon

Arrays allow storing multiple values for the same variable in computer memory. Static arrays have a fixed size set at initialization, while dynamic arrays can expand and contract during runtime. Most programming languages use zero-based indexing for arrays, where the first element is index 0 rather than 1. One-dimensional arrays store elements in a single list, while two-dimensional arrays use two indices like rows and columns to access elements. Data is typically loaded into two-dimensional arrays using nested loops to iterate through rows and columns.

Multistream in SIP and NoSIP @ OpenSIPS Summit 2025Lorenzo Miniero

Slides for my "Multistream support in the Janus SIP and NoSIP plugins" presentation at the OpenSIPS Summit 2025 event. They describe my efforts refactoring the Janus SIP and NoSIP plugins to allow for the gatewaying of an arbitrary number of audio/video streams per call (thus breaking the current 1-audio/1-video limitation), plus some additional considerations on what this could mean when dealing with application protocols negotiated via SIP as well.

"AI in the browser: predicting user actions in real time with TensorflowJS", ...Fwdays

With AI becoming increasingly present in our everyday lives, the latest advancements in the field now make it easier than ever to integrate it into our software projects. In this session, we’ll explore how machine learning models can be embedded directly into front-end applications. We'll walk through practical examples, including running basic models such as linear regression and random forest classifiers, all within the browser environment. Once we grasp the fundamentals of running ML models on the client side, we’ll dive into real-world use cases for web applications—ranging from real-time data classification and interpolation to object tracking in the browser. We'll also introduce a novel approach: dynamically optimizing web applications by predicting user behavior in real time using a machine learning model. This opens the door to smarter, more adaptive user experiences and can significantly improve both performance and engagement. In addition to the technical insights, we’ll also touch on best practices, potential challenges, and the tools that make browser-based machine learning development more accessible. Whether you're a developer looking to experiment with ML or someone aiming to bring more intelligence into your web apps, this session will offer practical takeaways and inspiration for your next project.

New Ways to Reduce Database Costs with ScyllaDBScyllaDB

How ScyllaDB’s latest capabilities can reduce your infrastructure costs ScyllaDB has been obsessed with price-performance from day 1. Our core database is architected with low-level engineering optimizations that squeeze every ounce of power from the underlying infrastructure. And we just completed a multi-year effort to introduce a set of new capabilities for additional savings. Join this webinar to learn about these new capabilities: the underlying challenges we wanted to address, the workloads that will benefit most from each, and how to get started. We’ll cover ways to: - Avoid overprovisioning with “just-in-time” scaling - Safely operate at up to ~90% storage utilization - Cut network costs with new compression strategies and file-based streaming We’ll also highlight a “hidden gem” capability that lets you safely balance multiple workloads in a single cluster. To conclude, we will share the efficiency-focused capabilities on our short-term and long-term roadmaps.

State-Dependent Conformal Perception Bounds for Neuro-Symbolic Verification o...Ivan Ruchkin

A poster presented by Thomas Waite and Radoslav Ivanov at the 2nd International Conference on Neuro-symbolic Systems (NeuS) in May 2025. Paper: https://arxiv.org/abs/2502.21308 Abstract: It remains a challenge to provide safety guarantees for autonomous systems with neural perception and control. A typical approach obtains symbolic bounds on perception error (e.g., using conformal prediction) and performs verification under these bounds. However, these bounds can lead to drastic conservatism in the resulting end-to-end safety guarantee. This paper proposes an approach to synthesize symbolic perception error bounds that serve as an optimal interface between perception performance and control verification. The key idea is to consider our error bounds to be heteroskedastic with respect to the system's state -- not time like in previous approaches. These bounds can be obtained with two gradient-free optimization algorithms. We demonstrate that our bounds lead to tighter safety guarantees than the state-of-the-art in a case study on a mountain car.

Build your own NES Emulator... with KotlinArtur Skowroński

For those who have ever wanted to recreate classic games, this presentation covers my five-year journey to build a NES emulator in Kotlin. Starting from scratch in 2020 (you can probably guess why), I’ll share the challenges posed by the architecture of old hardware, performance optimization (surprise, surprise), and the difficulties of emulating sound. I’ll also highlight which Kotlin features shine (and why concurrency isn’t one of them). This high-level overview will walk through each step of the process—from reading ROM formats to where GPT can help, though it won’t write the code for us just yet. We’ll wrap up by launching Mario on the emulator (hopefully without a call from Nintendo).

8 problem solving with the case logic structure

1. Data Structures and Algorithms The Case Logic Structure @ The case logic structure is made up of several or many sets of instructions, only one of which will be selected by the user and executed by the programmer. @ The form of the case logic structure is the following: CASE OF VARIABLE = constant 1: actions for VARIABLE = constant 1 = constant 2: actions for VARIABLE = constant 2 = constant 3: actions for VARIABLE = constant 3 . .
