RPA vs. Workflow: It’s Not Either/or… It’s Both

Aggregated on: Mon May 15 2023 23:15:33 GMT+0000 (Coordinated Universal Time)

Both workflow and robotic process automation (RPA) have an important place, albeit a very different one. It’s not always easy to know which to use and when. The hype around RPA could lead you to believe that RPA is the best choice for everything from order management to oven cleaning. But before you get out the oven cleaner, let’s dig a little deeper. Typically, we recommend using workflow for state-managed processes that are performed at a high scale and are mission-critical to the business. RPA is often best for repetitive human tasks. There’s also a grey area where you may start with RPA for a quick win — with the goal of moving to workflow to take advantage of its flexibility and robustness. The matrix below can help you frame the question.

IBM App Connect Enterprise CI Builds With On-Demand Service Provisioning

Aggregated on: Mon May 15 2023 23:15:33 GMT+0000 (Coordinated Universal Time)

The industry-wide move to continuous integration (CI) build, and test presents a challenge for the integration world due to the number and variety of resource dependencies involved, such as databases, MQ-based services, REST endpoints, etc. While it is quite common to automate testing using dedicated services (a “test” or “staging” database, for example), the fixed number of these services limits the number of builds that can be tested and therefore limits the agility of integration development. Containerization provides a way to increase CI build scalability without compromising quality by allowing a database to be created for each run and then deleted again after testing is complete. This does not require the integration solution to be deployed into containers in production and is compatible with deploying to integration nodes: only the CI pipeline needs to be able to use containers and only for dependent services.

How TiDB Implements Point-In-Time Recovery

Aggregated on: Mon May 15 2023 22:45:33 GMT+0000 (Coordinated Universal Time)

For database products, point-in-time recovery (PITR) is a crucial capability. It allows users to restore their databases to specific points in time to protect against accidental damage or user errors. For example, if data is accidentally deleted or damaged, PITR can restore the database to its state before that time, thereby avoiding the loss of important data. In this article, we’ll explore how PITR works with TiDB, an advanced, open-source, distributed SQL database. We’ll also discuss how we optimized PITR to maximize its stability and performance.

JSON to PDF Magic: Harnessing LaTeX and JSON for Effortless Customization and Dynamic PDF Generation

Aggregated on: Mon May 15 2023 22:00:33 GMT+0000 (Coordinated Universal Time)

In this tutorial article, we show how to control the layout and content of the PDF document via the JSON body of the API call with DynamicDocs API. We present three different JSON examples and produce three different types of documents using the same end-point. In each case, making changes to the PDF is done by editing the JSON payload. To do this, we utilize the power of LaTeX to control the layout of the PDF document. What is LaTeX? LaTeX is a programming language specifically designed for creating PDF documents. Source files in LaTeX have a .tex extension and are usually compiled into PDF format. While it's highly popular in academia for crafting dissertations and scholarly articles, LaTeX is also excellent for producing visually appealing documents. Its strength lies in the separation of content and stylistic rules, allowing for precise control over the document's appearance. However, a significant drawback of LaTeX is the steep learning curve involved in mastering the language for document layout.

Aggregated on: Mon May 15 2023 21:30:33 GMT+0000 (Coordinated Universal Time)

ChatGPT can be an excellent tool for those who know how to create prompts. The simplest form of prompting ChatGPT is to feed it the task and ask for results. However, this approach is unlikely to trigger the best response from the model. Instead, invest more time in prompt engineering, and provide ChatGPT with a better context of the situation, desired outcomes, data, constraints, etc. The following article offers a primer to creating ChatGPT prompts for Scrum practitioners to get you started running. You will learn the following:

GPT3.5-Turbo Versus GPT4

Aggregated on: Mon May 15 2023 21:30:33 GMT+0000 (Coordinated Universal Time)

There are thousands of articles about the difference between ChatGPT version 3.5 versus version 4. However, we have a unique technology that allows you to embed ChatGPT on your website. This makes our requirements fairly unique. Hence, none of these existing comparisons really provide any value for us. We, therefore, decided to compare ChatGPT and its GPT3.5-turbo model against GPT4 in our chatbot to see the differences. WARNING! GPT4 is 30 times more expensive than GPT3.5-turbo — so the quality and speed is not the only factor here. Unless you've got very deep pockets, you will obviously have to consider the price differences too.

Shift Left Testing Tutorial: Comprehensive Guide With Best Practices

Aggregated on: Mon May 15 2023 17:15:33 GMT+0000 (Coordinated Universal Time)

A shift left testing approach involves moving testing activities "left" or relatively "early" in the development cycle. Thus, testers are involved earlier in the software development life cycle, enabling them to identify bugs and bottlenecks at an earlier stage. In addition to improving the quality of the code and reducing the time it takes to complete the cycle, it helps ensure fewer defects are introduced to production. Organizations are constantly challenged to move faster in an agile environment. Typically, this entails shortening the delivery time while improving quality with each successive release at reduced costs.

Reducing Network Latency and Improving Read Performance With CockroachDB and PolyScale.ai

Aggregated on: Mon May 15 2023 16:45:33 GMT+0000 (Coordinated Universal Time)

Motivation CockroachDB makes multi-region simple. When CockroachDB spans geographically, we often need to add a minimum of two more regions for a multi-region cluster. This unique capability has many strengths but it comes at a cost. Oftentimes, our customers demand CockroachDB be available in regions where we see low demand, and bringing those regions online is not cost-effective to the organization. As of this writing, we support the most popular regions in GCP and AWS; some regions are not exposed in the cloud console but are available via support ticket. PolyScale operates a global network of PoPs (Points of Presence). Think of PoPs as regional database connections. This versatility provides a cost-effective solution to reduce global network latency by bringing the database closer to the end user. The network of PoPs spans multiple cloud providers, thereby bridging the gap between cloud providers. PolyScale complements CockroachDB in the way that CockroachDB can be more accessible in many more geographic locations and many other cloud providers than provided out of the box by Cockroach Cloud.

Microservices Decoded: Unraveling the Benefits, Challenges, and Best Practices for APIs

Aggregated on: Mon May 15 2023 14:45:33 GMT+0000 (Coordinated Universal Time)

In today's fast-paced software development landscape, microservices have emerged as a popular architectural pattern. But what exactly are microservices? In a nutshell, microservices are a way of structuring an application as a collection of loosely coupled, fine-grained services that communicate through lightweight protocols. This architectural style enables teams to develop and deploy services independently, offering flexibility and scalability to the software development process. The fundamental idea behind microservices is to break down an application into smaller, self-contained services, each responsible for a specific business capability. Let's take the example of an online marketplace application. Instead of treating the entire application as a monolithic entity, microservices architecture allows us to identify distinct features like search, shopping cart, payments, and order history as independent services. These services can be developed and maintained separately, promoting code modularity and enhancing overall system agility.

Fun Is the Glue That Makes Everything Stick, Also the OCP

Aggregated on: Mon May 15 2023 13:30:33 GMT+0000 (Coordinated Universal Time)

This is part two of my series on the OCP-17. In my first post, I explained why it’s still worthwhile to tackle the trick questions and arcane details of this exam. Each of us has our own sense of how much knowledge is good enough to get a job done, like writing Java code. The examiners at Oracle probably put the bar much higher than you. If you can’t somehow make the journey fun, you’re bound to give up. So, your motivation needs an upgrade, and you must put in the right practice. In this post, we will look at both. Amateur Versus Professional Practice Not all practice makes perfect. Poor practice doesn’t even make you proficient. It’s not the hours that count, although Malcolm Gladwell in Outliers claimed you need at least 10,000. This sweeping statement with its conveniently round number is questionable science, to say the least. Excellence itself is not a well-defined notion. People’s innate aptitudes are not created equal. Some are born geniuses. But most importantly, the hours you put in must be effective.

Boosting Similarity Search With Stream Processing

Aggregated on: Mon May 15 2023 13:30:33 GMT+0000 (Coordinated Universal Time)

The goal of similarity search and vector databases is to find similar results to the search query for unstructured data, such as text, images, and videos. The unstructured data first is vectorized, and stored in a vector format. There are publicly available tools to create vectors from unstructured data; similarly, there are vector databases to store and perform similarity searches. This is important because of the rising popularity of Large Language Models (LLMs) and their combination with vector databases. Here, we present a hybrid approach by taking the strengths of vector databases and boosting them with traditional search and filtering techniques based on real-time stream processing. Vector databases are good for building high-performance vector search applications. On the other hand, Hazelcast can be used for real-time stream processing and fast data storage for structured data (filters, tags, and contextual data). Some vector databases offer filtering on structural data, which can be used or replaced with Hazelcast. In either case, Hazelcast can be used to enrich your query results, from additional resources.

10 Traits That Separate the Best Devs From the Crowd

Aggregated on: Fri May 12 2023 22:15:32 GMT+0000 (Coordinated Universal Time)

In a Nutshell We work hard to improve our tech and soft skills. But our character traits, our mindset - we take it for granted. An innate, fixed part of who we are. And thus, we let it run on autopilot. This way of thinking is harmful. Not only is your mindset critical for a successful software development career (maybe even more than your skills), but it's also under your control. True senior devs acknowledge that character traits are malleable, are self-aware of their mindset, and deliberately work on it. This is the superpower that makes them stand out from the crowd and accelerates their career. In this post, I'll discuss the 10 most critical traits of a successful developer, why they are important, and share a few tips on how you can shape them. Three Things You Need To Succeed as a Software Developer Professional software development is a complex discipline that requires a diverse set of abilities to succeed. We can group them into three main categories: Technical Skills This is the most obvious group. To be a successful developer, you need to be good at your trade: programming languages and frameworks, clean code principles, architecture, testing, debugging, and so on. You also need to be skillful with your tools: version control, command line, and IDE.

Although there are a lot of compelling security features that can be used, the whole Istio (the sidecar) has to be deployed from day one. Recently, the Istio community has reimagined a new data plane — ambient mode — which will be far less resource-intensive. Istio ambient mesh is a modified and sidecar-less data plane developed for enterprises that want to deploy mTLS and other security features first and deploy an advanced network later. Ambient mesh has two layers:

Managing Data Residency: Concepts and Theory

Aggregated on: Fri May 12 2023 17:30:32 GMT+0000 (Coordinated Universal Time)

Cloud computing has opened a Pandora's Box of many original issues compared to sound old on-premise systems. I believe that chief among them is data residency or data location: Data localization or data residency law requires data about a nation's citizens or residents to be collected, processed, and/or stored inside the country, often before being transferred internationally. Such data is usually transferred only after meeting local privacy or data protection laws, such as giving the user notice of how the information will be used and obtaining their consent.

The dream of any software engineering team and organization is to achieve success in their software and impact the business directly. However, the most challenging point is explaining how to achieve this success and get metrics. In this video, you'll learn more about this through strategy and tactics in software engineering. When we talk about the metrics, it becomes even more challenging mainly because we look at the metrics focused on tech, such as the number of tasks, commits, more code, and deployment frequency. But delivering a version does not necessarily mean you're impacting the business. Let's start talking about this mistake: the passion for tech.

In our last post, we introduced you to the Manifold project and how it offers a revolutionary set of language extensions for Java, including the ability to parse and process JSON files seamlessly in Java. Today, we will take a look at another exciting feature of the Manifold project: string templates. But before we get to that, some of the feedback I got from the previous post was that I was unclear about Manifold. Manifold is a combination of an IDE plugin and plugins to Maven or Gradle. Once used we can enhance the Java language (or environment) almost seamlessly in a fluid way.

Enriching Kafka Applications With Contextual Data

Aggregated on: Fri May 12 2023 12:30:31 GMT+0000 (Coordinated Universal Time)

Developing high-performance large-stream processing applications is a challenging task. Choosing the right tool(s) is crucial to get the job done; as developers, we tend to focus on performance, simplicity, and cost. However, the cost becomes relatively high if we end up with two or more tools to do the same task. Simply put, you need to multiply development time, deployment time, and maintenance costs by the number of tools. Kafka is great for event streaming architectures, continuous data integration (ETL), and messaging systems of record (database). However, Kafka has some challenges, such as a complex architecture with many moving parts, it can’t be embedded, and it’s a centralized middleware, just like a database. Moreover, Kafka does not offer batch processing, and all intermediate steps are materialized to disk in Kafka. This leads to enormous disk space usage.

I contributed to PCRE and wrote two smaller regular expression engines, but I still regularly learn something new about this topic. This time, it's about a regex that never matches. When using character classes, you can specify the allowed characters in brackets, such as [a-z] or [aeiouy]. But what happens if the character class is empty?

Using Apache Pulsar and Spring Boot for Real-Time Stream Processing

Real-time stream processing has become a critical component of modern data-driven applications. Apache Pulsar is an open-source distributed messaging system that provides seamless horizontal scalability and low-latency processing of real-time data streams. Spring Boot is a popular Java framework that simplifies the process of building and deploying production-grade applications. In this article, we will explore how to use Apache Pulsar and Spring Boot for real-time stream processing. Getting Started With Apache Pulsar The first step in building a real-time stream processing application with Pulsar is to set up a Pulsar cluster. A Pulsar cluster consists of one or more brokers that handle incoming data streams and route them to the appropriate consumers. Pulsar provides a simple and straightforward way to set up a cluster using the Pulsar CLI tool.

For a better grasp of the subject under discussion, it would be preferable if you could first read Chris Koch's article: I Used GPT-3 to Find 213 Security Vulnerabilities in a Single Codebase. I had already written a lengthy comment to it. Then I decided to write another one. This time, I chose to put my thoughts into a complete post. I don't share the author's enthusiasm. Our trials with ChatGPT yielded far more modest and dubious findings, and you may read about them in the article: Is ChatGPT good enough at spotting bugs in code?

Repeatable Database Updates via Liquibase

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

The main purpose of this tutorial is to present a way of detecting modifications to a stored Liquibase change set that was previously applied and execute it again automatically. In order to illustrate this, a small proof of concept is constructed gradually. In the first step, the application configures Liquibase as its migration manager and creates the initial database schema. Then, modifications are applied to the running version, and lastly, the repeatable script is introduced and enhanced. Set-Up Java 17 Spring Boot v.3.0.2 Liquibase 4.17.2 PostgreSQL 12.11 Maven Proof of Concept As PostgreSQL was chosen for the database layer of this service, first, a new schema is created (liquirepeat). This can be easily accomplished by issuing the following SQL command after previously connecting to the database.
