Bolster Intelligent Document Processing With Robotic Process Automation

Aggregated on: 2022-12-06 15:58:58

Over the past few years, there have been countless new technology developments that have advanced the workforce — from video and chat platforms that keep employees connected to automation solutions that boost productivity. One of the more popular developments has been intelligent document processing (IDP), used to extract data from structured and unstructured content to automate high-volume, repetitive document processing tasks. In fact, IDP has become so popular that, in 2022, the IDP market size was estimated to be at about 1.1 billion USD, but according to Research and Markets, it’s expected to grow to 5.2 billion USD by 2027. Despite the popularity of IDP, there are some iterations of the tool that lack the processing power needed to automate complex end-to-end business processes. Fortunately, robotic process automation (RPA) can step in to bolster your tech stack and solutions.

Introduction to Interface-Driven Development (IDD)

Aggregated on: 2022-12-06 15:58:58

During my work on different projects and using different languages, frameworks, styles, and idioms, I found out that there are no silver bullets on how to design software. Starting from a set of requirements we need to implement, we have preferences that we should first write code and then test; on the other side, we have the TDD approach emerging for years now, as well as some other approaches (design-first, etc.). Here I want to explain one approach that I find to work very well when designing and implementing software, especially if it is a component or library. The main question here is how you start designing your code. Do you start with some kind of drawing, write tests first (TDD), or start imidate with an implementation?

Securing Developer Tools: A New Supply Chain Attack on PHP

Aggregated on: 2022-12-06 04:43:58

Supply chain attacks are a hot topic for development organizations today. Last year, in the largest ever software supply chain attack, a backdoor infected 18,000 SolarWinds customers. Earlier this year, a security researcher was able to breach Apple, Microsoft, PayPal, and other tech giants using a new supply chain attack technique. The underlying design exploited by these attacks is that all modern software is built on top of other third-party software components, often without clear visibility of all the downloaded packages. And while reusing many components allows to speed up the development process, infecting the supply chain is a very effective and subtle attack vector to compromise many organizations at once.

5 Trends That Will Shape Application Security in 2023

Aggregated on: 2022-12-06 04:13:57

The digital transformation and cloud-native movements are driving DevOps practices and open-source code libraries increase the speed at which applications are developed and delivered. However, security has not always been a top priority in the DevOps journey. In order to ensure that applications are secure, it is essential to make security a part of the process. Organizations can achieve this integration by including security in the development process, automating security tasks, and fostering a culture of security throughout the entire organization. I’ll outline five current trends shaping the future of application security and how modern AppSec programs can get ahead of the curve by reducing developer friction, integrating security into CI/CD pipelines, and making security a first-class citizen of software development workflows. By understanding and acting on these trends, organizations can make security a more integral part of their software development process.

Simplify Database Geo-Redundancy Backup With Cloud Storage Services

Aggregated on: 2022-12-06 02:43:57

Geo-redundancy is a disaster recovery practice that backs up data in geographically distributed data centers. This approach safeguards against incidents and guarantees business continuity. For database systems, there are mainly two ways to be geo-redundant: cold (offline) backup and hot (online) backup. Cold backup is more widely used because it’s cheaper and has less impact on online performance. However, it’s not easy to build a cost-effective, scalable cold backup solution. There can be challenges in scalability, operations, and costs. In this article, I will offer a solution to these challenges: geo-redundancy backup with cloud storage service.

Streaming in Mule

The task is made even more difficult when working with remote teams to get the job done.

Progressive Delivery in Kubernetes: Analysis

Aggregated on: 2022-12-05 20:43:57

The native Kubernetes Deployment Objects support the Rolling Update strategy, which provides a basic guarantee during an update, as well as limitations: Few controls over the speed of the rollout. Inability to control traffic flow to the new version. Readiness probes are unsuitable for deeper, stress, or one-time checks. No ability to check external metrics to verify an update. No ability to automatically abort and roll back the update. For the reasons above, in a complex production environment, this Rolling Update could be risky because it doesn't provide control over the blast radius, may roll out too aggressively, and there is no rollback automation in case of failure.

Create Dynamic Code Review Checklists With CodeSee Code Automation

Aggregated on: 2022-12-05 20:43:57

I’ve been a longtime advocate of pull request templates. These templates allow you to provide instructions to developers creating pull requests in your repos so that they will be reminded to include all the relevant information you need to properly review their code. Pull request templates are a great place to include checklists as additional reminders. These might include to-dos like remembering to write unit tests, self-reviewing your code, or doing a security audit. Sometimes though, these checklists can get long. You may have so many important items that developers begin to ignore them. Or perhaps some of the checklist items are only relevant in specific situations or when certain files are changed. While each item is important, they may not all always be applicable.

Comparing Styles of Container-Based Deployment for IBM App Connect Enterprise

Aggregated on: 2022-12-04 23:28:57

When deploying IBM App Connect Enterprise integrations in containers there are options around how we deploy the runtime, the configurations, the integration flows and environment specific data. All the movable parts can either be “included in the image,” “configured at deploy time,” or a mixture of the two. In this article, we will explore these different deployment options, the benefits of each, and considerations for taking each approach. What Changes When We Deploy IBM App Connect Enterprise in Containers? From IBM App Connect v11, the integration server can be deployed on its own, without the need for an integration node to look after it. This is most relevant in a container scenario where the container platform itself takes on the management of the individual integration servers. Additionally, all the IBM App Connect Enterprise configuration required is defined alongside the container providing a more portable deployment of integrations. Container based deployment has many notable differences to a traditional deployment, such as:

The Beginner’s Guide to MQTT Retained Messages

Aggregated on: 2022-12-02 19:43:55

What Are Retained Messages? If you know MQTT even for just a little bit, you may already know that for each MQTT message, there is a topic name, and there is the payload. If you dig a little deeper, you’ll find that there are also message properties and flags. One of the flags is called Retain, which is what this post is about. Upon receiving a message with the Retain flag set, the MQTT broker must store the message for the topic to which the message was published, and it must store only the latest message. So the subscribers which are interested in this topic can go offline, and reconnect at any time to receive the latest message instead of having to wait for the next message from the publisher after the subscription.

SaaS Application Patching and Upgrade Testing: Preparing for Readiness is the Key

Aggregated on: 2022-12-01 20:58:55

Cloud technologies have revolutionized the software application development and delivery process. As more and more companies are realizing the benefits of reduced infrastructure costs, automated production deployments, and increased security in the cloud, commercial off-the-shelf products are on the rise to provide business-ready solutions to the customer. The products that were traditionally developed, bundled, and deployed on the premises of the customer or hosted in-house to provide the applications and services are on the transformation path to the cloud. These Prem applications always have challenges as the customers are on different versions of the product, on different infrastructure versions, and specific customizations for the customer need more maintenance; scaling the applications based on the usage is often more a reactive approach than a proactive approach. Software-as-a-service (SaaS) applications alleviate the vendor selling the product from the above challenges as all its customers are on the same version of the cloud infrastructure through patches and upgrades, which the customers can’t avoid. The ability to scale up or down depending on the customer's requests is proactive. Also, it provides enhanced customer experience by releasing new features regularly without the customers having to wait long for their favorite features.

So, in this part of the article, you'll learn many terms related to compilation theory. We discussed many of them in part one — do take a look if you haven't already!

3 Risks Due to Lack of Routine Database Maintenance

Aggregated on: 2022-12-01 18:13:55

Relationships with databases are surprisingly similar to those between people. If we don’t regularly dedicate time and resources to maintaining and nurturing them, they may not be there when we need them the most. Since it has become increasingly clear to industry executives, C-suites, and other thought leaders that data is the hottest commodity, protecting yours should be a top concern. There is no reason to risk losing your entire database, which could have catastrophic consequences. Let’s examine a few of the risks of failing to perform regular database maintenance. 1. False Conclusions About Productivity You might have one database, or you might have several. In either case, all data is organized in structures sharing one trait: associated indexes that allow data to be located efficiently. Database indexes need constant updates and adjustments. Without regular maintenance, indexes become fractured, making data retrieval cumbersome and time-consuming. From the outside, it could seem that you need to add staff to your team to complete tasks on time, while the underlying problem is a system running slowly due to unmaintained indexes. False conclusions about productivity levels can have devastating financial impacts.

Apache Ranger and AWS EMR Automated Installation and Integration Series (1): Solutions Overview

Aggregated on: 2022-11-30 19:13:54

System security usually includes two core topics: authentication and authorization. One solves the problem of “Who is s/he?” and the other solves the problem of “Does s/he have permission to perform an operation?” In the big data area, Apache Ranger is one of the most popular choices for authorization, it supports all mainstream big data components, including HDFS, Hive, HBase, and so on. As Amazon EMR rolls out native ranger (plugins) features, users can manage the authorization of EMRFS(S3), Spark, Hive, and Trino all together. For authentication, an organization usually has its own centralized authentication infrastructure, i.e., Windows AD or OpenLDAP; however, for most big data components, Kerberos is only supported authentication mechanism, so users usually need to integrate Windows AD/OpenLDAP and Kerberos together to unify authentication. We will focus on how to implement automated installation and integration for Amazon EMR and Apache Ranger. This series is composed of four articles. Each article will introduce a completed solution against different technology stacks.

Web Resource Caching: Client-Side

Aggregated on: 2022-11-30 18:13:54

The subject of Web resource caching is as old as the World Wide Web itself. However, I'd like to offer an as-exhaustive-as-possible catalogue of how one can improve performance by caching. Web resource caching can happen in two different places: client-side - on the browser and server-side. This post is dedicated to the former; the next post will focus on the latter. Caching 101 The idea behind caching is simple: if a resource is time- or resource-consuming to compute, do it once and store the result. When somebody requests the resource afterwards, return the stored result instead of computing it a second time. It looks simple - and it is, but the devil is in the detail, as they say.
