IronRuby is a Ruby implementation that compiles Ruby code to .NET Intermediate Language. It allows Ruby code to run on the .NET Common Language Runtime and interoperate with .NET libraries. IronRuby was started by Microsoft but is now an open source project. It enables Ruby developers to build applications that integrate with existing .NET systems and libraries. However, IronRuby is still missing support for some Ruby standards like OpenSSL and has a lower test passing rate than MRI Ruby.

Future of PERL in IT

Nexiilabs

Perl is a script programming language, which has a lot of similarity in syntax to “c” language. This also includes UNIX like sed;awk;tr etc. Perl is an interpreted language which can be assembled before execution in “c” code/bytecode. Once Perl is compiled, it is as fast as any other compiled “c” program. The Perl language is often considered as the best choice for the development of CGI (i.e Common gateway interface) due to its good text manipulation feature; even though it conducts only binary files.

Ayesha Siddika

Welcome To Ruby Rails Web Development Ruby on Rails Development Benefits and Pitfalls Understanding how the many components of digital design and development are connected is crucial for web developers. Each pillar supports the span, much like a bridge, and if any one of them fails, the entire structure falls. Both poor design and poorly written code can obliterate even the most complex design solutions. Every component contributes to the final result, a user-friendly product. We have provided you with some background information on the terms, procedures, and tools used in web development in previous posts. This article will carry on that theme. We're going to discuss one of the widely used web development tools, Ruby on Rails, and share some of its advantages and disadvantages with you. brief history A brief history will be presented first. Ruby is an open source, dynamic, object-oriented programming language with an emphasis on efficiency and productivity. The original version of the language, Ruby, which was created by Yukihiro "Matz" Matsumoto, was initially made available in the 1990s. Today, it provides power to popular services like Basecamp, Hulu, the original Twitter, and Living Social. Because Ruby offers a framework that supports a high level of developer flexibility, many businesses, including BBW, Cisco, CNET, IBM, JP Morgan, NASA, and Yahoo, employ it in some capacity. The open-source Ruby on Rails web application framework is designed to increase programmers' long-term productivity. From his work on the project management tool Basecamp at the web application firm also known as Basecamp, David Heinemeier Hansson extracted Ruby on Rails. In July 2004, Hansson first made Rails available as open source. Even well-known companies like Amazon and eBay have Rails projects. From my work on Basecamp, a project collaboration tool from 37signals, Rails (Ruby on Rails) was extracted. It was therefore driven by needs rather than predictions. And I think a large reason why we're doing so well right now is because of it. I didn't make an effort to consider what certain programmers could require for a dream job. I merely constructed what I required to complete my work cheerfully. David Heinemeier Hansson, the author of Ruby on Rails, is a different interviewee. What is Ruby on Rails? Model-view-controller (MVC) is how Rails apps work. This technique is utilized by numerous other web frameworks, including AngularJS (JavaScript), Django (Python), and CakePHP (PHP).Models, Views, and Controllers are the three components that make up the apps, according to this. These parts perform the following functions: They include the functionality needed to modify and get the many types of data the app uses. A model is represented as a class in Rails. They are not low-level data types like strings or arrays. Create the logic that connects views and models (and the data they are linked with). They perform input processing, make method calls, and send data to

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?

Power Grid Model The global energy transition is placing new and unprecedented demands on Distribution System Operators (DSOs). Alongside upgrades to grid capacity, processes such as digitization, capacity optimization, and congestion management are becoming vital for delivering reliable services. Power Grid Model is an open source project from Linux Foundation Energy and provides a calculation engine that is increasingly essential for DSOs. It offers a standards-based foundation enabling real-time power systems analysis, simulations of electrical power grids, and sophisticated what-if analysis. In addition, it enables in-depth studies and analysis of the electrical power grid’s behavior and performance. This comprehensive model incorporates essential factors such as power generation capacity, electrical losses, voltage levels, power flows, and system stability. Power Grid Model is currently being applied in a wide variety of use cases, including grid planning, expansion, reliability, and congestion studies. It can also help in analyzing the impact of renewable energy integration, assessing the effects of disturbances or faults, and developing strategies for grid control and optimization. What to expect For the upcoming meetup we are organizing, we have an exciting lineup of activities planned: -Insightful presentations covering two practical applications of the Power Grid Model. -An update on the latest advancements in Power Grid -Model technology during the first and second quarters of 2024. -An interactive brainstorming session to discuss and propose new feature requests. -An opportunity to connect with fellow Power Grid Model enthusiasts and users.

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).

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

Mutation Testing for Task-Oriented Chatbots

Pablo Gómez Abajo

Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots. To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

Introduction of Cybersecurity with OSS at Code Europe 2024

Hiroshi 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.
