Essential Security Measures for PDF Documents

Aggregated on: 2023-11-15 17:27:32

Portable Document Format (PDF) is a file format that contains a comprehensive representation of a document, encompassing elements like text, fonts, graphics, and other components. PDF is often considered a secure document format due to its inherent security features. These capabilities enable the incorporation of password protection, encryption, and digital signatures into a file. PDF security is important for several reasons. Information is often shared over the internet, and ensuring the privacy and integrity of sensitive data during such exchanges is paramount. Whether the PDF contains a legal contract, a confidential business report, or personal information, proper PDF security ensures that only authorized individuals can access or modify the contents of these documents. PDF security not only protects intellectual property but can also help you comply with legal and regulatory requirements. This makes it an indispensable tool in today's interconnected world.

Architecture Patterns: Strangler Pattern

Aggregated on: 2023-11-15 16:27:32

The Strangler Pattern, first described by Martin Fowler, is a software architectural pattern that describes a method of gracefully migrating a legacy system incrementally rather than in a big-bang approach. It is named after the Strangler Fig, a type of vine that slowly grows on a tree and eventually replaces it. Similarly, in the software context, the Strangler Pattern involves building a new system around the boundaries of the old system, allowing you to slowly replace parts of the old system with components of the new system over time. Many Software engineers will be confronted with system migration in their careers; technology is growing faster, and humans need time to adapt and maintain their systems, which can become old sometimes even before they have time to finish it. A strangler pattern is an approach that allows migration without a big bang, which can be very stressful for teams and is often condemned to failure. This pattern is very efficient in the context of large systems because it allows people to gain confidence in the ability to make the migration, providing a multitude of small successes that are much harder to achieve in a one-shot.

A Tale of Two Intersecting Quality Attributes: Security and Performance

Aggregated on: 2023-11-15 13:57:32

“I want to build a system that is highly secure, scalable, reliable, performant, compliant, robust, resilient, and durable.” Add more adjectives to that to really dream of a quintessential solution. Is that even possible? Where do we make the two ends meet — aspirations vs reality? What is the right intersection point? To answer that, we probably need to categorize the above, and maybe a few more quality attributes, into two major cross-cutting concerns — security and performance, and see where and how to strike a balance between the two, often referred to as architectural or design trade-offs. Security is a requirement for each and every component involved in the overall system, which may include devices, networks, data, services, applications, storage, etc. However, it is not always mutually exclusive in the sense that the security of one component can partly or fully ensure the security of other components, depending on how they are configured. For example, we often offload SSL at the gateway level as the data is expected to travel within the internal network after that, which is deemed secure to a certain extent. Likewise, the performance of the overall system depends upon how each individual component is behaving. We may have a fast rendering UI but a slow API response that really sucks, or vice versa.

Pagination of an Infinite List of Records in Salesforce

Aggregated on: 2023-11-15 12:27:32

What Is Pagination? Put simply, it's page-by-page navigation. It's a way to display a large amount of homogeneous information by dividing the content into pages. Many Salesforce developers, myself included, often encounter pagination when displaying a significant volume of data on the user interface. On one of my projects, we were presenting phone numbers in a data table. However, in certain cases, the data wouldn't display, as the information retrieval took too long. Users were unable to access any data. So, why did this happen? 1. Contacts Were Selected Through Several Nested Database Queries We were dealing with multiple levels of parent-child relationships between Contacts and child objects. Due to business logic requirements, we needed to filter contacts based on filters applied both to the contacts themselves and to filters applied to the child objects of the contacts.

The Evolutionary Leap: Why NoSQL Databases Are Transforming Real-Time Analytics

Aggregated on: 2023-11-15 12:27:32

In the data-driven landscape of today, real-time analytics are more than just a competitive advantage — they're a necessity for any enterprise seeking to stay ahead of the curve. While SQL databases have been the stalwart foundation of data storage and retrieval for decades, they are increasingly viewed as insufficient for the needs of real-time analytics. Enter NoSQL databases, a technology that is redefining the paradigms of data analytics and management. The Constraints of SQL in a Real-Time World SQL databases, characterized by their tabular structure and rigid schemas, have been tried and true for business applications requiring ACID (Atomicity, Consistency, Isolation, Durability) transactions. However, these very characteristics that make them suitable for certain applications limit their ability to scale horizontally, adapt to different data types, or operate with low latency — all essential features in the context of real-time analytics.

The Four Steps of Regression Testing

Aggregated on: 2023-11-14 21:42:32

This article provides a structured approach to create and update a regression test suite. What kinds of tests should be in a regression test suite? Which regression tests should be run, how do you respond to regression tests that fail, and how does a regression test suite evolve? These questions and other considerations are explored in a step-by-step manner. I will first explore the basic dynamics and considerations of regression testing. Then I will provide a set of steps that can help bring long-term software stability from regression testing. Nuts and Bolts of Regression Testing Let's assume that we did a couple of changes in our software code, any kind of changes. How can we be confident that these changes will not negatively affect our code overall? One way to achieve confidence is to perform thorough regression testing. Write and execute tests to check and explore how our code behaves after our changes. So, the more tests we write and execute, the more confident we will be? Yes, but there are practical costs to be considered as well — the time, effort, and money required to write, execute, and maintain a regression test suite.

Feedback Loops: The Secret Ingredient for Efficient Platform Engineering Teams

Aggregated on: 2023-11-14 19:42:32

Many organizations that successfully launch and enable a platform engineering team to allow the rest of the engineering teams and developers with applications, infrastructure, tools, and services see challenges over time and eventually fail due to gaps in collaboration and communication with internal and external consumers. Let’s dive deep into the gaps between application and platform teams in enterprise and large-scale organizations. One of the primary reasons is the need for a proper feedback loop to engage often with consumers. Lack of constant engagement with application engineering teams creates alignment gaps and trust. Feedback loops play a role in platform engineering for the following reasons. Benefits of Feedback Loop in Platform Engineering Continuous Improvement: Feedback loops allow platform engineers to gather insights and suggestions from users, developers, and other stakeholders. This valuable information helps identify areas that require enhancement and guides the development of features or improvements. Over time, this iterative process leads to a more efficient, reliable, and user-friendly platform. User-Centric Design: Platforms exist to serve users; feedback loops are necessary to understand their evolving needs. Regular feedback from users assists platform engineers in tailoring their work to meet these requirements. As a result, the platform becomes more user-centric. They are aligned with the organization’s goals. Issue Resolution: Feedback loops provide an avenue for identifying and addressing issues. When users encounter problems or bugs, they can report them promptly. Platform engineers can respond swiftly, minimizing disruptions and ensuring a user experience. Innovation: Through feedback loops, platform engineers gain insights into emerging technologies, trends, and user expectations. This information has the potential to spark ideas and uncover opportunities for incorporating features, technologies, or services that can enhance the platform’s competitiveness and value. Enhancing Efficiency and Streamlining: Feedback loops can provide insights into areas of the platform that require optimization or streamlining. For instance, if users consistently report performance issues or bottlenecks, platform engineers can prioritize these areas for improvement to enhance efficiency. Alignment with Business Objectives: Feedback loops ensure the platform aligns with business goals. They enable platform engineers to assess whether the platform contributes to the company’s success and adjust if needed. Data-Driven Decision Making: Feedback loops serve as a data source for decision-making. By collecting and analyzing feedback, platform engineers can make informed choices about which improvements or changes should take priority. Risk Mitigation: Regular feedback helps identify security vulnerabilities, compliance issues, or other risks. This proactive approach allows for mitigation of problems and enhances the stability and reliability of the platform. User Satisfaction: Ultimately, the success of a platform is measured by how satisfied its users are. Feedback loops play a role in platform engineering by providing insights into user satisfaction. These insights guide efforts to improve the user experience and maintain a user base. Agile Development: Within development practices, feedback loops serve as an element. They enable platform engineers to improve based on changing requirements and user feedback. Impact of Missing Feedback Loop on Platform Engineering Stagnation: When platform engineers don’t receive feedback, they might continue working based on assumptions or outdated practices. This can cause a lack of progress in the platform development, resulting in missed opportunities for improvement and innovation. Misalignment: The platform can only align with the changing needs of users and the organization if there is feedback. This misalignment can lead to wasted resources since the platform may need to support the intended applications or services effectively. Quality Issues: With feedback, platform engineers may be aware of any issues or bugs in the system. This lack of awareness can result in quality problems such as reliability issues, security vulnerabilities, and performance bottlenecks. Wasted Resources: Without feedback, platform engineers may invest time and effort into features or components that aren’t valuable or necessary. This waste of resources can detract from focusing on what matters to users and the business. Decreased User Satisfaction: When there is no user feedback, it’s possible that the platform won’t meet user expectations. Consequently, user satisfaction could decrease. Dissatisfied users may seek solutions or workarounds, diminishing the platform’s value. Impact of Missing Feedback Loop on Application Engineering Inadequate Capabilities: Application engineering teams heavily rely on the platform to offer services and functionalities. However, without feedback loops, the platform might need more features or performance levels required by applications, limiting their functionality and potential. Inefficiency Concerns: Application engineers may need help working around limitations or deficiencies of the platform. This may result in inefficiencies and longer development timelines, leading to project delays and increased development costs. Reliability Challenges: When continuous improvement and optimization are lacking for the platform, applications can face reliability issues. This can cause downtime service interruptions. Negatively impact the user experience. Frustration Levels: The limitations or unresponsiveness of the platform to the application engineering team’s needs can lead to frustration. Consequently, it strains the relationship between both teams. Reduces productivity. Missed Opportunities: Without feedback mechanisms, application engineering teams may need to be aware of enhancements or features that could boost their applications. As a result, they take advantage of opportunities to create competitive products. Conclusion But, when platform engineering lacks feedback loops, it can lead to a misaligned platform. This means the platform will need help to keep up with the changing needs of application engineering teams and users. Consequently, this can result in inefficiency, quality problems, lower user satisfaction, and missed opportunities for both platform and application engineering teams. Establishing feedback loops is essential to encourage collaboration, continuous improvement, and the overall success of both teams and the organization. Feedback loops are vital in platform engineering for creating and sustaining platforms prioritizing user needs. They empower platform engineers to adapt and innovate, ensuring the platform aligns with business objectives and user expectations. These loops are a part of iterative development practices that contribute to the success of the platform and the organization it serves.

We'll explore seven of the features released in IBM App Connect Enterprise 12.0.10.0 and provide a high-level overview of each; Toolkit: Simple JSON Mapping within the Discovery Connector Request nodes. New button to open workspace file system location. WebUI: New Record and Replay views with Hex and Base64 encoding. Resource Manager views. New Change Data Capture node for integrating with PostgreSQL and DB2. Built-in ODBC driver for integration with PostgreSQL databases. Importing and exporting credentials using the mqsivault command. Configuring an Integration Server's JRE - Java 11 changes. Open Telemetry platform support extended to include AIX and pLinux. Toolkit Simple JSON Mapping Within the Discovery Connector Request Nodes For the last few mod releases of App Connect Enterprise, we have rapidly expanded the number of available Discovery Connector message flow nodes - both input nodes to trigger a message flow and also mid-flow request nodes. In total, the Toolkit now provides 86 such nodes.To further improve the usability for developers wanting to integrate with application endpoints, we have also provided an easy way to map between data structures. App Connect Enterprise 12.0.10.0 introduces the concept of executing mapping logic as part of a Discovery Connector node. This is done using the JSONata expression language capabilities which were first made available as part of the web browser-based Designer authoring experience. For more information about JSONata, which itself is an open-source technology, check out the website here, which also includes a JSONata exerciser.To demonstrate this new Toolkit message flow capability, consider a simple scenario of triggering a flow when a GitHub issue is created and then writing a message to a Slack channel. Previously, a scenario like this one would have required an intervening message flow node such as a Compute node, JavaCompute node, or Graphical Data Map node between the GitHub Input and the Slack Request nodes, but now we can wire the nodes together directly, and apply the mapping task as part of the Slack Request node:

7 Common Mistakes in a Multi-Cloud Journey

Aggregated on: 2023-11-14 14:42:32

Your executive leadership launched a ‘Cloud First’ strategy with much fanfare a few months ago. At first, it was simple and seemed inexpensive to move workloads to your primary cloud service provider. But now, you feel the cloud provider is taking you for granted — you’ve lost all price negotiation power, and SLAs and response levels are not what they used to be. To make matters worse, your new cloud service bill seems to be out of control. You are confronted with what is known as the “Cloud Paradox” — the very benefits that made the move to the cloud as a compelling strategy are now causing costs to spiral, stifling innovation, and making it near impossible to repatriate workload from the cloud.

Software Hazard Identification

Aggregated on: 2023-11-14 14:12:32

Custom Software is critical and is an integral part of many complex medical devices. Some of these medical devices are high-risk medical devices as the failure can result in non-serious injury or serious injury or in some cases, even death for the persons using them. Because of this, the software contained in high-risk medical devices must be safe. To enforce this safety aspect, the regulatory requirements ISO 14971 and IEC 62304 that govern software development in medical devices establish the overall mechanism for risk management in the design and development of software for medical devices. The main stages of software risk management consist of Risk Analysis, Risk evaluation, and Risk control.

Anatomy of a High Availability Kubernetes Cluster

In my previous article, I hinted at explaining how Ansible can be used to expose applications running inside a high availability K8s cluster to the outside world. This post will show how this can be achieved using a K8s ingress controller and load balancer. This example uses the same setup as last time around: virtual machines running under the default Windows Hypervisor (Hyper-V). To make room for the addition of a proxy each VM had to give up some RAM. With the exception of the initial master and the Ansible runner, each of the remaining nodes received an allocation of 2000MB.

Data Governance Best Practices

Aggregated on: 2023-11-14 13:12:32

In the digital age, data governance isn't a luxury; it's a necessity. From multinationals to fledgling startups, organizations are becoming increasingly data-centric. The myriad technologies at our disposal — SQL databases, NoSQL systems, REST APIs, GraphQL, and more — offer great power but also bring complex challenges, especially in managing data. Quality, consistency, and security are three pillars that make or break your data strategy. In essence, irrespective of your technology stack, data governance serves as the bedrock of data integrity, quality, and security. Why Data Governance Matters In 2006, British mathematician Clive Humby declared, "Data is the new oil." But like crude oil, raw data becomes genuinely valuable only when refined. Poor data governance is akin to a dysfunctional refinery: it compromises the quality of the oil, sometimes with catastrophic results. Whether it's incorrect data that leads to faulty business decisions or a data breach that tarnishes a company's reputation and incurs hefty fines, the stakes are undeniably high. Regulatory frameworks like GDPR and CCPA further raise the bar for data management, making governance not just advisable but legally required.
