Staying ahead of the multi-core revolution with CDT debug
The use of multi-core chips is now a reality for computer systems. With such technology however, software is becoming more complex, and problems exceedingly difficult to debug. The C/C++ Development Tooling (CDT) already provides advanced debugging features such as non-stop, multi-process, reversible debugging, tracepoints and more. In addition to those features, the CDT community has undertaken the implementation of a rich set of multi-core debugging features which will be available with GDB towards a Linux target and will also allow the integration of proprietary debuggers and targets.
This presentation will describe the efforts of the CDT's Multi-Core Debugging Work Group, where different companies and community members are joining forces to make multi-core debugging a reality for the CDT and Eclipse. We will cover the goals that have been established, the features that have been implemented or are actively being worked on, and the road ahead. We plan on showing many of the features that we aim for with actual demos, including the displaying of cores in a debug session, the dynamic grouping of cores/processes/threads, the pinning and cloning of debugging views, and a configurable layout of the debugging elements.

Halvar Flake: Why Johnny can’t tell if he is compromisedArea41
This document discusses the difficulty of determining if a computer system is compromised. It outlines several checks that could be done to verify control, such as verifying signatures on software binaries, firmware, and scripts.

Introduction of Cybersecurity with OSS at Code Europe 2024Hiroshi SHIBATA
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.

Chris Jones, Director of Product Management at BrainChip , presents the “Temporal Event Neural Networks: A More Efficient Alternative to the Transformer” tutorial at the May 2024 Embedded Vision Summit.
The expansion of AI services necessitates enhanced computational capabilities on edge devices. Temporal Event Neural Networks (TENNs), developed by BrainChip, represent a novel and highly efficient state-space network. TENNs demonstrate exceptional proficiency in handling multi-dimensional streaming data, facilitating advancements in object detection, action recognition, speech enhancement and language model/sequence generation. Through the utilization of polynomial-based continuous convolutions, TENNs streamline models, expedite training processes and significantly diminish memory requirements, achieving notable reductions of up to 50x in parameters and 5,000x in energy consumption compared to prevailing methodologies like transformers.
Integration with BrainChip’s Akida neuromorphic hardware IP further enhances TENNs’ capabilities, enabling the realization of highly capable, portable and passively cooled edge devices. This presentation delves into the technical innovations underlying TENNs, presents real-world benchmarks, and elucidates how this cutting-edge approach is positioned to revolutionize edge AI across diverse applications.

Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
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.

Editor's Notes
Information about the OSI network model would not available in the Student Guide, but you need to tell students in brief that OSI model provides various layers to establish network between computers. Following are the seven network layers of OSI network model: Physical layer : Helps convert bit stream in to different signals, such as electric and light. Data link layer : Helps encode and decode data packets into bits. Network layer : Helps creating logical path for data transfer using techniques, such as switching and routing. Transport layer : Helps transport data between end-systems. Session layer : Helps establish, manage, and terminate connection between applications. Presentation layer : Helps represent data in network format. Application layer : Helps process application for end-users.
Information about the other network coverage areas can also be discussed here. Following are the various network coverage areas: A Personal Area Network (PAN): which is a network of devices used by a single individual, such as a user’s cellular phone with a wireless hands-free handset. A Campus Area Network (CAN): which covers an area equivalent to an academic campus or business park. A CAN is typically owned or used exclusively by one company, school, or organization. A Metropolitan Area Network (MAN): which covers an area equivalent to a city or other municipality. A Global Area Network (GAN): which is any worldwide network.
