That’s where array formulas swoop in to save the day. In this blog post, I'm going to show you how these fancy formulas can jazz up your data game.

Avoid Smart Contract Hacks With Fuzz Testing

Aggregated on: 2023-08-29 20:01:36

Quite possibly, nothing in web3 is more critical — and difficult to do well — than smart contract testing. For individual developers and small teams, the requisite testing tools are often too expensive and hard to use. Fortunately, a new breed of testing techniques is emerging, ones that are both affordable and accessible. In my previous article, I talked about one of the most popular techniques: fuzzing. Fuzzing is a dynamic testing technique capable of identifying errors and vulnerabilities that standard tests don’t typically identify. I also talked about how one of the most powerful fuzzing tools — Diligence Fuzzing — just released support for one of the most powerful development frameworks: Foundry. This combination complements your manual audits by providing new vulnerability detection techniques that you can use to avoid costly contract rewrites.

Introduction to the Queue Data Structure

Aggregated on: 2023-08-29 14:46:36

A queue is a linear data structure in computer science that adheres to the First-In-First-Out (FIFO) principle. It is a group of elements where each element is added and removed sequentially. Operating systems, network protocols, and web applications are just a few of the applications that use queues. In circumstances where it is necessary to manage a series of tasks or events, queues are frequently used. For example, in an operating system, the operating system uses a queue to manage processes. A process is added to the end of the queue when it is launched. The first process in the queue is selected by the operating system and set to running when it is prepared to execute a process. Up until each and every process in the queue has been finished, this process keeps going.

Sveltos: Automate Configuration Updates for Kubernetes Applications

Aggregated on: 2023-08-28 22:01:36

ConfigMaps and Secrets are Kubernetes resources designed to decouple configuration details from application code, fostering a clear separation between configuration data and the application logic. This separation yields several compelling advantages, making the practice of mounting ConfigMaps and Secrets a crucial component of Kubernetes deployments. Configuration Flexibility: Applications often require various configuration settings to function optimally across different environments. By mounting ConfigMaps, developers can modify configuration parameters without altering the application code. This not only streamlines the development process but also allows for on-the-fly adjustments, facilitating smooth transitions between development, testing, and production environments. Enhanced Security: Secrets, such as sensitive authentication tokens, passwords, and API keys, contain critical information that must be safeguarded. Instead of hardcoding these sensitive details directly into the application code, they can be stored as Secrets and mounted into pods only when necessary. This mitigates the risk of inadvertent exposure and helps maintain a higher level of security. React to Configmap/Secret Changes Sveltos is an open-source Kubernetes project to deploy add-ons in a multitude of Kubernetes cluster. Sveltos can also be instructed to watch for changes in ConfigMaps and Secrets and triggers rolling upgrades for the associated resources, ensuring that applications stay up-to-date.To enable this functionality, simply set the reloader field to true in the ClusterProfile, as demonstrated in the following example YAML configuration:

You can mitigate issues that come up by promoting a version to all users only when you’re confident that it is performant and reliable. If it fails in production, the impact radius is restricted to a subset of users, and the update can be rolled back immediately.

Sampling Strategies in Distributed Tracing: A Comprehensive Guide

Aggregated on: 2023-08-28 17:01:36

If you are running a distributed system where each request talks to more than a couple of services, databases, and a queuing system, pinpointing the cause of an issue is not a trivial affair. The complexity increases as the number of services increases, as east-west traffic goes up, as teams get split up, and as data tends to eventual consistency. There are a plethora of tools aiming to solve this problem to various degrees. Perhaps the most critical tooling in this workflow is distributed tracing. We have even argued that a well-implemented distributed tracing solution might subsume logging into its fold. Yet, in reality, tracing end-to-end request flows has been an afterthought in most companies, as postulated in this article. One of the biggest challenges plaguing widespread adoption is the sheer volume of trace data. Capturing, storing, indexing, and querying from this massive dataset will not only impact performance and add significant noise but also break the bank :)

Software-In-The-Loop (SIL) Testing and Its Benefits

Aggregated on: 2023-08-25 20:46:34

Software-in-the-loop (SIL) testing is a crucial methodology in software development and verification processes. It plays a pivotal role in ensuring the software component's functionality, performance, and reliability by subjecting it to rigorous testing within a simulated environment. SIL testing involves integrating the software with a model of the system or component it will interact with and evaluating the combined behavior using simulation.To conduct SIL testing for medical devices, the first step is to create a comprehensive model that accurately represents the system or component with which the software will interact. This model typically includes the relevant physical and environmental factors the software needs to respond to, such as sensor inputs, external stimuli, and other critical parameters. By incorporating these factors, the model emulates real-world conditions and scenarios. Once the model is established, the software is integrated, forming a combined system that can be tested using simulation techniques. The simulated environment allows for the execution of a wide range of test cases, including typical and exceptional scenarios. For instance, in the case of a patient monitoring system, the software would be integrated with a model representing the patient's physiological systems, such as heart rate, blood pressure, and oxygen levels. The software would then be subjected to various simulated scenarios, such as changes in vital signs, alarms and alerts, and potential device malfunctions.During SIL testing, the behavior and performance of the software are closely monitored and analyzed. The testing team assesses how the software responds to different inputs and stimuli, ensuring it functions correctly and generates accurate outputs. By thoroughly testing the software under various conditions, SIL testing helps uncover any potential defects, anomalies, or issues that may arise during usage.One of the primary benefits of SIL testing in the context of medical devices is early Verification. By testing the software component before integration with the physical hardware, developers can identify and rectify potential issues early, reducing the likelihood of costly rework and ensuring higher software quality. SIL testing also saves cost and time by reducing dependency on physical prototypes and specialized testing equipment. Furthermore, simulating various scenarios and conditions during SIL testing enables comprehensive test coverage, including edge cases and rare events that may be challenging to reproduce in real-world situations.SIL testing is particularly valuable for safety validation in medical devices. It allows developers to evaluate the software's response to safety-critical functionalities and verify the effectiveness of fail-safe mechanisms. By simulating potential failure scenarios, SIL testing aids in identifying and mitigating risks associated with the software component, ultimately enhancing the safety of the medical device.There are several benefits to SIL testing, including:Early Verification: SIL testing allows for early verification of the software's functionality and performance before integrating it with the actual hardware. This helps identify and rectify potential issues or defects in the software early, reducing the likelihood of costly rework later in the development process.Cost and Time Savings: By performing SIL testing, developers can significantly reduce the need for physical prototypes or specialized testing equipment. This leads to cost savings in terms of hardware procurement and setup. Additionally, SIL testing can be performed parallel to hardware development, resulting in time savings and faster time-to-market for medical devices.Test Coverage: SIL testing enables comprehensive test coverage by controlling various test scenarios that may be difficult to reproduce in real-world conditions. This includes edge cases, rare events, and abnormal scenarios that may be challenging to recreate during traditional testing approaches.Safety Validation: Medical devices require rigorous Validation to ensure patient well-being. SIL testing allows for the evaluation of safety-critical functionalities and the verification of fail-safe mechanisms. By simulating potential failure scenarios, SIL testing aids in identifying and mitigating risks associated with the software component of the device.Iterative Development: SIL testing facilitates iterative development by providing a controlled environment for testing and refining the software. It allows quick modifications, updates, and enhancements to be tested without requiring extensive hardware integration, accelerating the development cycle and enabling agile development methodologies.Overall, SIL testing is a valuable technique for software development teams, as it allows them to test software in a simulated environment and detect potential issues early in the development process. SIL testing ensures software components' reliability, performance, and safety in medical devices, contributing to enhanced quality, reduced risks, and improved patient care.

In an era where digital imagery comes alive and artistic expressions are shaped by algorithms, have you ever taken a moment to appreciate the wonder of AI transforming simple phrases into vibrant visuals? Or looked at an aged photograph, only to see it rejuvenated into a sharp, clear memory? At the core of this technological marvel, within the realms of deep learning, exists a captivating duo - the Generative Adversarial Networks, commonly known as GANs. Picture two artists: one, an innovator, conjuring worlds from fleeting ideas; the other, a realist, distinguishing fact from fiction. The innovator, our Generator, spins stories from randomness, while the realist, our Discriminator, evaluates their genuineness. In a blend of collaboration and competition, they refine each other's skills. The innovator's creations become so realistic that even the most astute realist is deceived.

Logging is arguably the most important element of your observability solution. Logs provide foundational and rich information about system behavior. In an ideal world, you would make all the decisions about logging and implement a consistent approach across your entire system. However, in the real world, you might work with legacy software or deal with different programming languages, frameworks, and open-source packages, each with its own format and structure for logging. With such a diversity in log formats across your system, what steps can you take to extract the most value from all your logs? That’s what we’ll cover in this post. We’ll look at how logs can be designed, the challenges and solutions to logging in large systems, and how to think about log-based metrics and long-term retention.
