Non-Volatile Memory

Aggregated on: Thu May 11 2023 20:30:31 GMT+0000 (Coordinated Universal Time)

Non-volatile memory access (NVM) is a technology that has gained significant attention over the past few years. It has brought a revolution in the memory storage industry by providing various benefits over traditional storage technologies. NVM refers to a type of memory that retains data even after the power has been turned off. This means that data stored in NVM is non-volatile and is suitable for use in a wide range of applications. In this article, we will explore the various forms of NVM, their advantages, limitations, and their potential applications. Forms of NVM NVM comes in various forms, including flash memory, magnetic RAM (MRAM), nanotube RAM (NRAM), resistive RAM (RRAM), and phase-change memory (PCM). Flash memory is the most commonly used form of NVM, and it is used in USB drives, digital cameras, and smartphones. Flash memory works by trapping electrons in a transistor’s floating gate. This makes it non-volatile as the information is retained when the power is off. The limitations of flash memory include wear-out and a limited number of write cycles.

Opportunities for Growth: Continuous Delivery and Continuous Deployment for Testers

Aggregated on: Thu May 11 2023 16:45:31 GMT+0000 (Coordinated Universal Time)

Development practices are constantly changing, and as testers, we must embrace change. One of the changes that we can experience is the move from monthly or quarterly releases to continuous delivery or continuous deployment. In addition, this move to continuous delivery or deployment offers testers the chance to learn new skills. A project that makes monthly or quarterly releases has a familiar rhythm, and the team builds toward the release date. The testers must test all the cards and conduct manual regression testing. Every test in the manual scripts needs to be executed, and possibly a report needs to be made on the results of these tests. Once the release has been made, it is possible that there will be bugs that were in the release that need to be fixed. The testers will also need to start running the same manual regression tests on the next release and report on them again. Testing for monthly or quarterly releases is a repetitive process. This process has been compared to the Greek myth of Sisyphus, who had to roll a stone to the top of a hill, and then when the stone rolled to the bottom of the hill, he had to roll it to the top of the hill again.

Securing Access, Encryption, and Storage Keys

Aggregated on: Wed May 10 2023 20:45:30 GMT+0000 (Coordinated Universal Time)

The cloud platforms provide customers with technology and tools to protect their assets, including the most important one — data. At the time of writing, there's a lot of debate about who's responsible for protecting data, but generally, the company that is the legal owner of the data has to make sure that it's compliant with (international) laws and standards. In the UK, companies have to adhere to the Data Protection Act, and in the European Union, all companies have to be compliant with the General Data Protection Regulation (GDPR). Both the Data Protection Act and GDPR deal with privacy. International standards ISO/IEC 27001:2013 and ISO/IEC 27002:2013 are security frameworks that cover data protection. These standards determine that all data must have an owner so that it's clear who's responsible for protecting the data. In short, the company that stores data on a cloud platform still owns that data and is therefore responsible for data protection.

What Are Events? Process, Data, and Application Integrators

Aggregated on: Wed May 10 2023 19:30:30 GMT+0000 (Coordinated Universal Time)

I first started developing SAP "Workflows" 25 years ago: five years prior to Gartner announcing that 'Event-Driven Architecture' (EDA) would be the "next big thing" to follow on from 'Service-Oriented Architecture' (SOA) – SOA likewise still in its infancy in 2003. What's interesting about this is that Workflows themselves are, and always have been, 'Event-Driven.' The advancement of any given Workflow from one step to the next step always depends upon a particular event (or events) occurring, such as 'PurchaseOrder.Approved'. As you might already know, SAP has been developing ERP software since 1972, making it by far one of the most experienced software vendors in the world to have built their product offerings around 'Business Processes': around 'Process Integration.' What's also interesting to note in this regard is that SAP very recently confirmed the tight link between 'Workflows' and 'Process Integration,' by regrouping and rebranding their Cloud-based "Workflow Management" solution into a new offering: "Process Automation" – apparently the first time in 25 years that their Workflow solution carries a name other than "Workflow …"

Classloaders in JVM: An Overview

Aggregated on: Wed May 10 2023 19:00:30 GMT+0000 (Coordinated Universal Time)

Classloaders are an essential part of the Java Virtual Machine (JVM), but many developers consider them to be mysterious. This article aims to demystify the subject by providing a basic understanding of how class loading works in the JVM. What Are Classloaders In the Java Virtual Machine (JVM), classes are loaded dynamically and found through a process called class loading. Class loading is the process of loading a class from its binary representation (usually a .class file) into memory so that it can be executed by the JVM. This is where we need classloaders. Class loaders are used to load .class files into the memory.

Why Run Open Source Data Technologies in Your Own Cloud Account

Aggregated on: Wed May 10 2023 18:30:30 GMT+0000 (Coordinated Universal Time)

Organizations have an increasingly important choice to make when enlisting managed services or database-as-a-service (DBaaS) providers for their open-source data technologies: go with one of the many providers that require data management to be hosted within their own domains, or insist on running in your own (cloud) provider account (RIYOA). In general, most DBaaS providers offer the simplicity of having just one bill to pay, which covers all cloud costs and instances. However, that simplicity comes at costs beyond the monetary—reduced visibility of what’s going on with your data, limitations to developer flexibility when trying to utilize data-layer technologies and restrictions on access to data itself. While less of an out-of-the-box option, retaining RIYOA control avoids these shortcomings and makes it significantly easier to shift to a new provider if a change becomes preferable at some point.

UI testing is a technique that ensures the UI of a website or mobile application is user-friendly and meets the expected customer or end-user requirements. It validates the visual design and layout, and functionality of the user interface to make sure it performs as intended. User interfaces encompass everything a user sees and interacts with on a website. It is the space where the website and the user interact. When you first visit a website, the first thing you interact with is the UI or interface of the application. A website's design decides a user's first impression. The user experience of an interactive web application can make or break a deal for you, and that is why it's crucial to perform UI testing of your websites or web applications.

In this series of simulating and troubleshooting performance problems in Scala, let’s discuss how to make threads go into a blocked state. A thread will enter into a blocked state when it cannot acquire a lock on an object because another thread already holds the lock on the same object and doesn’t release it. Scala Blocked Thread Program Here is a sample program, which would make threads go into a blocked state.

How To Scan and Validate Image Uploads in Java

Aggregated on: Tue May 09 2023 04:30:29 GMT+0000 (Coordinated Universal Time)

Direct image upload processes create a highly efficient path between client-side users and a website’s underlying file storage instances, significantly benefiting both ends of the client/web service relationship. Due largely to the ever-increasing availability (and affordability) of cloud storage resources for independent developer projects and small business ventures, we see the option to upload our own image files more and more frequently everywhere we look online, growing in tandem with steady demand for new forms of social engagement and commerce. The trouble is, however, that file upload security is a very serious issue - and image files are rather easily exploited by client-side threat actors. Image files aren’t unique in this respect, of course (many common file formats including PDF, DOCX, etc., for example, can house a variety of hidden threats), but their monumental value on the internet – a mostly visual platform – sets them apart as one of the more expedient vessels for malicious content.

Batch Request Processing With API Gateway

Aggregated on: Tue May 09 2023 04:00:29 GMT+0000 (Coordinated Universal Time)

Batch request processing is a powerful technique used in web development to improve the performance of APIs. It allows developers to group multiple API requests into a single HTTP request/response cycle. In other words, a single API request from a client can be turned into multiple API requests to a set of backend servers, and the responses are aggregated into a single response to the client. It can significantly reduce the number of round trips between the client and server. In this article, we'll explore how to implement batch request processing in Apache APISIX and look at some use cases where it can be beneficial.
