Unsafe at Any Speed: 7 Dirty Secrets of the Security Industrydigitallibrary
Do you ever feel that your trusted security providers are failing to tell you the whole truth? Would you like to hear what they aren't telling you? It is time for intellectual honesty. We entrust the security industry to protect us from unacceptable risk. However, competing vendor priorities often prevent them from sharing and discussing all security truths. Some "Lies of Omission" merely delay countermeasures. More serious "Dirty Secrets" have created and perpetuated unacceptable blind spots and exposure. First, we expose the 7 Dirty Secrets of the Security Industry. Second, we highlight key security trends deserving your attention. Lastly, we will outline practical ways to command intellectual honesty from your trusted security providers.
The document provides an overview of Peter Wood, an expert in ethical hacking and cybersecurity. It discusses the concept of "consumerisation" where employees want to use their personal devices for work purposes. While this raises security concerns for IT departments, the document argues that tightly controlling devices is ineffective and employee expectations around mobility and flexibility will result in loosened corporate control over tools. It outlines some of the mobile security risks at different layers of devices and examples of malware targeting smartphones.

The document discusses best practices for creating effective presentation slides. It recommends that slides should contain no more than 6 bullet points per slide, with text no smaller than 12 point font. Graphics and design are important to engage the audience visually and demonstrate care and customization. Templates should include the presenter's name and date in a consistent footer. The focus of a presentation should be the presenter's story and message, not the slides themselves, which are merely visual aids. Details that are not important to the central message should be removed. Demonstrations can enhance technical topics by bringing facts to life through active examples and description of processes.
Toothpick is a simple logging framework for Smalltalk that separates the concerns of whether, where, and what to log. It includes loggers to define where events are logged, like to the transcript, files, or network. Logging formatters define what is logged, like simple text or XML. Logging policies determine whether an event is logged based on its category and level. The LoggingMultiplexer manages multiple loggers. LoggingEvents contain log messages that are sent to the multiplexer.

The rapid expansion of the Internet of Things has fostered convenience and connectedness for consumers. It has also opened the door for creative hackers. Recently, hackers used hundreds of thousands of common internet-connected devices in consumers’ homes, without the owners’ knowledge, to launch a DDoS attack that temporarily brought down crucial parts of the internet’s infrastructure.
Attacks in the past have shown that passwords in IoT devices provide insufficient security. Additionally, IoT devices are too constrained for implementing biometric functions.
The question then becomes how to authenticate to such devices and can the industry adopt a standardized approach despite a highly fragmented IoT landscape. This presentation by Rolf Lindemann of Nok Nok Labs, explores how FIDO Authentication can provide convenient and strong authentication in an array of IoT use cases.

Workshop: Identifying concept inventories in agile programmingESUG
This document discusses the development of a concept inventory to identify common misconceptions in agile programming and object-oriented development. The project aims to strengthen collaboration between INRIA/Lille and ÉTS/UQAM by creating a concept inventory that can be used to improve teaching of agile development with object-oriented languages like TypeScript, JavaScript, and Pharo. The methodology involves identifying misconceptions, proposing a concept inventory, and validating it in courses by measuring understanding before and after instruction. A workshop will help identify initial misconceptions in Smalltalk/Pharo by capturing them in a collaborative tool.
This document proposes integrating documentation into the Pharo language metamodel and environment to improve documentation support. It suggests making documentation first-class citizens in Pharo by providing built-in support and a minimal API, which would allow tight integration with development tools and future extensions without requiring grammar changes or large efforts. This could improve documentation quality by enabling direct references between code and documentation and automatic logging of documentation usage.
The Pharo Debugger and Debugging tools: Advances and RoadmapESUG
This document outlines advances and the roadmap for debugging tools in Pharo. It discusses recent improvements to the debugging infrastructure, including architectural changes and new debugging commands. It also describes upcoming work, such as additional infrastructure improvements, an emergency debugger, support for meta-object protocols, a redesigned user experience, a remote debugger, and improved documentation. The document concludes by inviting participants to help evaluate new debugging experiments.
The document describes Sequence, a pipeline modeling and discrete event simulation framework developed in Pharo Smalltalk. Sequence allows describing system resources, building blocks that use those resources, assembling scenarios from blocks, collecting information during simulated runs, and interactively exploring system traces. The framework implements a discrete event simulation engine with event streams that model periodic processes and resources. Sequence provides tools for evaluating system performance through simulation before complete hardware is available.
Migration process from monolithic to micro frontend architecture in mobile ap...ESUG
This document discusses migrating a monolithic mobile application called CARL Touch to a micro frontend architecture. It presents a migration process involving three steps: 1) analysis of the monolithic codebase, 2) identification of potential micro frontends, and 3) transformation of the codebase to implement the identified micro frontends. Previous experiments at Berger-Levrault involving two teams migrating CARL Touch provided insights. The proposed process uses static and dynamic analysis, code visualization and clustering techniques to help identify optimal micro frontends and transform the codebase in a semi-automated manner.
Analyzing Dart Language with Pharo: Report and early resultsESUG
This document summarizes an analysis of the Dart programming language using tools in the Pharo environment. It describes generating a parser for Dart using SmaCC, which produces an AST. It also details defining a Famix meta-model for Dart and the Chartreuse-D importer that creates a FamixDart model from the AST. Future work is outlined, including improving SmaCCDart, continuing to develop the FamixDart meta-model, and handling dynamic types when importing associations. The goal is to analyze Dart and explore modeling Flutter applications.
Transpiling Pharo Classes to JS ECMAScript 5 versus ECMAScript 6ESUG
This document summarizes research on transpiling Pharo classes to JavaScript using ECMAScript 5 versus ECMAScript 6. It finds that transpiling to ES6 provides benefits like significantly faster load times, improved benchmark performance up to 43%, and more idiomatic code compared to ES5. However, fully emulating Smalltalk semantics like metaclass inheritance remains challenging when targeting JavaScript.
The document presents an approach for automated test generation from software models and execution traces. Key aspects of the approach include using metamodels to represent the codebase, values, and desired unit test structure. Models are built from the codebase and traces, then transformations are applied to generate unit tests conforming to the test metamodel. Abstract syntax trees are used to export the generated tests to code. The approach aims to generate tests that are relevant, readable and maintainable without relying on existing tests. An example demonstrates generating a JUnit test from an application class.
Genetic programming is used to generate unit tests by evolving test code via genetic algorithms to maximize coverage. Tests are represented as chromosomes of object and message statements. The genetic algorithm selects tests based on coverage, combines tests through crossover, and replaces tests in the population over generations to find optimal test sequences. Future work includes improving path exploration and comparing with other test generation tools.
Threaded-Execution and CPS Provide Smooth Switching Between Execution ModesESUG
Threaded execution and continuation-passing style (CPS) allow for smooth switching between execution modes in Zag Smalltalk. Threaded execution interprets code as a sequence of addresses like bytecode but is 2.3-4.7 times faster, while CPS passes continuations explicitly like in functional languages and is 3-5 times faster than bytecode. Both approaches allow fallback to debugging. The implementation shares context and stack between modes to easily switch with proper object structures.
Exploring GitHub Actions through EGAD: An Experience ReportESUG
This document summarizes an experience report on exploring GitHub Actions through EGAD, a tool for GitHub Action analysis. It discusses three key lessons learned: 1) Composing a story by documenting tasks and linking documentation to code, 2) Navigating custom views to conduct research, and 3) Supporting onboarding of researchers by assigning mentors, scheduling meetings, and encouraging use of resources. EGAD takes workflow YAML files, wraps them in a domain model to provide context, and allows inspecting examples to fully explore the GitHub Actions domain model.
Pharo: a reflective language A first systematic analysis of reflective APIsESUG
This document analyzes the reflective features and APIs in Pharo, a reflective programming language. It presents a catalog of Pharo's reflective APIs and analyzes how they relate to metaobjects. The analysis highlights areas for potential improvement, such as providing solutions for intercession on state reads/writes and addressing constraints when changing an object's class. The document contributes to understanding Pharo's reflective design and its evolution over time.
The document discusses garbage collector tuning for applications with pathological allocation patterns. It begins by explaining the motivation and issues caused by pathological patterns, such as applications taking over an hour and a half to run. It then provides an overview of garbage collection and how allocation patterns can impact performance. The document dives into two specific tuning techniques - increasing the full GC threshold to prevent premature full GCs from being triggered, and increasing the tenuring threshold to avoid large objects residing in the remembered set and slowing down scavenges. These tunings resulted in significant performance improvements for the sample DataFrame application, reducing the run time from over an hour and a half to around seven minutes.
Improving Performance Through Object Lifetime Profiling: the DataFrame CaseESUG
This document discusses improving garbage collection performance in Pharo through object lifetime profiling. It presents Illimani, a lifetime profiler developed for Pharo. Illimani was used to profile the lifetimes of objects created when loading a large DataFrame. The profiling revealed that most objects had short lifetimes, suggesting the garbage collector could be tuned. Tuning the garbage collector parameters based on the lifetime profiles improved the performance of loading the DataFrame.
This document discusses the past, present, and future of Pharo DataFrames. It began as a student project but has evolved into a mature project with dedicated engineers, improving performance and adding functionality. Future plans include further performance enhancements, adding more functionality, better integration with other Pharo projects, and support for big data. Evaluation of DataFrames is also planned.
This document discusses issues with thisContext in the Pharo debugger not correctly representing the execution context and being the DoIt context instead. This was fixed in Pharo12 by making thisContext a variable object that is wrapped in a DoItVariable, so the debugger context is used. When inspecting or doing DoIt, the doIt Variable is pushed and read to provide the proper execution context.

A New Architecture Reconciling Refactorings and TransformationsESUG
This document discusses reconciling refactorings and transformations in software engineering. It proposes a new architecture where refactorings decorate transformations by checking preconditions and composing multiple transformations. Refactorings ensure transformations are applied safely while transformations focus on model changes. Open questions remain around precondition handling and composition semantics. The goals are to reduce duplication, support custom refactorings/transformations, and provide a modern driver-based user interface.

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.

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.
