Want to Become a Senior Software Engineer? Do These Things

Aggregated on: 2025-06-13 19:13:13

In my experience working with and leading software engineers, I have seen mid-level Engineers produce outcomes worthy of a Senior, and seniors who are only so in title. High-performing mid-levels eventually overtook under-performing seniors. How you become a Senior Software Engineer is important. If you become a Senior because you're the last man standing or the one with the longest tenure. I am afraid that future upward movement may be challenging. Especially, if you decide to go elsewhere. I have been fortunate to directly mentor a couple of engineers to become Senior, and witness the journey of others.

AI Agent Architectures: Patterns, Applications, and Implementation Guide

Aggregated on: 2025-06-13 18:13:13

Architecture is something I am very much interested in. As I was exploring AI agents, I was curious to understand the agentic architectures. That led me to this awesome resource, The 2025 Guide to AI Agents, published by IBM on their Think page. One of the sections of the guide is around architecture. The architecture section explains that agentic architecture refers to the design and structure enabling AI agents to automate workflows, reason through tasks, and utilize tools to achieve their objectives. This architecture is built to support autonomous, goal-driven behavior by allowing agents to perceive their environment, process information, and act independently within defined rules and constraints.

Aggregated on: 2025-06-13 17:13:13

Cybersecurity encompasses multiple different domains, including network isolation, platform security and infrastructure security. However, one thing that we less frequently discuss, but use more than often is cryptography. Whether it’s HTTPS, data encryption in databases, disk encryption, or technologies like VPNs and blockchains, cryptography is one of the fundamental building blocks. As part of this article, lets try to decipher the cryptography concept. First and Foremost, What Is Cryptography? Simply put, it is the method of protecting information so that only intended people can read or access it. To better understand the definition let's consider a simple example.

Understanding the Circuit Breaker: A Key Design Pattern for Resilient Systems

Aggregated on: 2025-06-13 16:13:14

Reliability is critical, specifically, when services are interconnected, and failures in one component can lead to cascading effect on other services. The Circuit Breaker Pattern is an important design pattern used to build fault tolerant and resilient systems. Particularly in microservices architecture. This article explains the fundamentals of the circuit breaker pattern, its benefits, and how to implement it to protect your systems from failure. What is the Circuit Breaker Pattern? The Circuit Breaker Pattern is actually inspired by electrical circuit breakers you see at your home, which is designed to prevent system failures by detecting faults and stopping the flow of electricity when problems occur. In software, this pattern monitors service interactions, preventing continuous calls/retries to a failing/failed service, which could overload the service with problem. by “Breaking” the circuit between services, this pattern allows a system to gracefully handle failures and avoid cascading problems.

RAG vs. CAG: A Deep Dive into Context-Aware AI Generation Techniques

Aggregated on: 2025-06-13 14:13:13

As artificial intelligence systems become core components of everything from enterprise workflows to everyday tools, one thing is becoming crystal clear: context matters. It's no longer enough for a model to simply string together grammatically correct sentences. To truly add value—whether as a legal assistant, an AI tutor, or a customer support bot—an AI system needs to deliver the right answer at the right time, grounded in real-world knowledge and tuned to the situation at hand. That’s where two key techniques come into play: Retrieval-Augmented Generation (RAG) and Context-Aware Generation (CAG). These two approaches offer different solutions to the same challenge: how to make large language models (LLMs) smarter, more reliable, and more useful.

Exploring the IBM App Connect Enterprise SELECT, ROW and THE Functions in ESQL

Aggregated on: 2025-06-13 13:13:13

Let’s talk about SELECT in ESQL—and I don’t mean database queries (although they are somewhat similar). I mean using SELECT to slice and dice message data inside IBM App Connect Enterprise (ACE). Think of it like SQL, but for navigating the message tree instead of a table. This post is all about the different ways you can use SELECT in ACE: returning arrays, rows, or just that one perfect value. To clarify, I’ve built out a quick demo flow with a very simple message structure, grabbed the outputs, and broken it all down for you. We’ll look at:

Memory Leak Due to Uncleared ThreadLocal Variables

Aggregated on: 2025-06-13 12:13:13

In Java, we commonly use static, instance (member), and local variables. Occasionally, we use ThreadLocal variables. When a variable is declared as ThreadLocal, it will only be visible to that particular thread. ThreadLocal variables are extensively used in frameworks such as Log4J and Hibernate. If these ThreadLocal variables aren’t removed after their use, they will accumulate in memory and have the potential to trigger an OutOfMemoryError. In this post, let’s learn how to troubleshoot memory leaks that are caused by ThreadLocal variables.

Modernizing Financial Systems: The Critical Role of Cloud-Based Microservices Optimization

Aggregated on: 2025-06-13 11:13:13

Legacy systems in financial institutions often lead to scalability bottlenecks, security risks, and poor resiliency. In the modern digital economy, banks, payment providers, and fintech firms need infrastructure that is cost-effective, agile, and resilient. Cloud-based microservices have emerged as a modern approach to address these needs. By breaking monolithic systems into modular services, financial firms can accelerate innovation, reduce downtime. By achieving these, they can meet rising expectations for secure and real-time digital transactions. Understanding Cloud-Based Microservices in Fintech What are Microservices? Microservices are an architectural style where an application is built through a modular approach instead of a large applications. Financial services are broken into small, independent services that communicate among themselves securely. This ensures that the Financial system is resilient, which means if one service fails, the rest are running. It provides scalability, which implies each service can be scaled based on the needs without impacting others. It also ensures secure systems where each service follows its strict security guidelines.

KubeVirt: Can VM Management With Kubernetes Work?

Aggregated on: 2025-06-12 21:13:13

KubeVirt offers a bridge between virtual machines and containerized environments. As an open-source project, its standout feature is the ability to run VMs and containers side by side. But while the concept is promising, several caveats remain for organizations that need to support critical at-scale VM workloads. The CNCF project also reflects how containers are not going to replace VMs, while the reverse may be true in the long term for many use cases.

HTAP Using a Star Query on MongoDB Atlas Search Index

Aggregated on: 2025-06-12 20:13:13

MongoDB is often chosen for online transaction processing (OLTP) due to its flexible document model, which can align with domain-specific data structures and access patterns. Beyond basic transactional workloads, MongoDB also supports search capabilities through Atlas Search, built on Apache Lucene. When combined with the aggregation pipeline, this enables limited online analytical processing (OLAP) functionality suitable for near-real-time analytics. Because MongoDB uses a unified document model, these analytical queries can run without restructuring the data, allowing for certain hybrid transactional and analytical (HTAP) workloads. This article explores such a use case in the context of healthcare. Traditional relational databases employ a complex query optimization method known as "star transformation" and rely on multiple single-column indexes, along with bitmap operations, to support efficient ad-hoc queries. This typically requires a dimensional schema, or star schema, which is distinct from the normalized operational schema used for transactional updates. MongoDB can support a similar querying approach using its document schema, which is often designed for operational use. By adding an Atlas Search index to the collection storing transactional data, certain analytical queries can be supported without restructuring the schema.

The Missing Infrastructure Layer: Why AI's Next Evolution Requires Distributed Systems Thinking

Aggregated on: 2025-06-12 19:13:13

The recent announcement of KubeMQ-Aiway caught my attention not as another AI platform launch, but as validation of a trend I've been tracking across the industry. After spending the last two decades building distributed systems and the past three years deep in AI infrastructure consulting, the patterns are becoming unmistakable: we're at the same inflection point that microservices faced a decade ago. The Distributed Systems Crisis in AI We've been here before. In the early 2010s, as monolithic architectures crumbled under scale pressures, we frantically cobbled together microservices with HTTP calls and prayed our systems wouldn't collapse. It took years to develop proper service meshes, message brokers, and orchestration layers that made distributed systems reliable rather than just functional.

AI-Native Platforms: The Unstoppable Alliance of GenAI and Platform Engineering

Aggregated on: 2025-06-11 20:13:12

Let's be honest. Building developer platforms, especially for AI-native teams, is a complex art, a constant challenge. It's about finding a delicate balance: granting maximum autonomy to development teams without spiraling into chaos, and providing incredibly powerful, cutting-edge tools without adding superfluous complexity to their already dense workload. Our objective as Platform Engineers has always been to pave the way, remove obstacles, and accelerate innovation. But what if the next, inevitable phase of platform evolution wasn't just about what we build and provide, but what Generative AI can help us co-build, co-design, and co-manage? We're not talking about a mere incremental improvement, a minor optimization, or a marginal new feature. We're facing a genuine paradigm shift, a conceptual earthquake where artificial intelligence is no longer merely the final product of our efforts, the result of our development toils, but becomes the silent partner, the tireless ally that is already reimagining, rewriting, and redefining our entire development experience. This is the real gamble, the challenge that awaits us: transforming our platforms from simple toolsets, however sophisticated, into intelligent, dynamic, and self-optimizing ecosystems. A place where productivity isn't just high, but exceptionally high, and innovation flows frictionlessly.

From ETL to ELT to Real-Time: Modern Data Engineering with Databricks Lakehouse

Aggregated on: 2025-06-11 17:28:12

The data engineering landscape has rapidly changed over the past few years, shifting from the classical ETL (Extract, Transform, and Load) model to the more modern ELT (Extract, Load, Transform) model. In the ETL approach, data was transformed before being stored, which reduced flexibility. ELT reverses this process by first loading raw data into data lakes or warehouses and then transforming it within these environments, enabling more agile, on-demand analytics. However, as data volumes and business requirements have increased, ELT has become inadequate for many real-time use cases. Today, organizations need rapid access to insights to maintain operational agility, which has led to a growing demand for real-time data processing capabilities. Leading this shift is the Databricks Lakehouse solution, which provides a unified framework that combines the strengths of data lakes with the power of data warehouses. This fully integrated platform enables organizations to move quickly, make data-driven decisions, and maintain flexibility across diverse workloads.

Converting List to String in Terraform

Aggregated on: 2025-06-11 16:13:12

In Terraform, you will often need to convert a list to a string when passing values to configurations that require a string format, such as resource names, cloud instance metadata, or labels. Terraform uses HCL (HashiCorp Configuration Language), so handling lists requires functions like join() or format(), depending on the context. How to Convert a List to a String in Terraform The join() function is the most effective way to convert a list into a string in Terraform. This concatenates list elements using a specified delimiter, making it especially useful when formatting data for use in resource names, cloud tags, or dynamically generated scripts.

Evaluating Similariy Digests: A Study of TLSH, ssdeep, and sdhash Against Common File Modifications

Aggregated on: 2025-06-11 14:13:12

The field of digital forensics often uses signatures to identify malicious executables. These signatures can take various forms: cryptographic hashes can be used to uniquely identify executables, whereas tools like YARA can help malware researchers identify and classify malware samples. The behavior of files— functions exported, functions called, IP addresses and domains they connect to, files written or read—also provide useful indicators that a system has been compromised. Cryptographic hashes, YARA rules and indicators of compromise are usually compared against curated databases of trusted or malicious signatures, such as those maintained by the National Software Reference Library and MalwareBazaar. Hashes like MD5 and SHA256 are designed to change drastically even with minor modifications to the original executable, making it easy for malware authors to evade. Modern cloud environments make it easy to evade behavioral detection as well, allowing threat actors to tailor their malware to specific platforms. In general, matching against feeds of known indicators misses unknown or undiscovered threat vectors.

Cognitive Architecture: How LLMs Are Changing the Way We Build Software

Aggregated on: 2025-06-11 11:13:12

Software architecture has long been rooted in object-oriented and, later, service-oriented paradigms. These models have helped teams build modular systems, isolating behavior into manageable services that communicate over well-defined APIs. As systems grew, microservices brought benefits like scalability and decoupling, but also introduced significant complexity in orchestration. Today, we're witnessing a fundamental shift. The growing influence of foundation models, particularly large language models (LLMs), is changing how we approach software design. These models aren't just code libraries; they can understand context, reason about goals, and generate human-like responses. This has led to the rise of agent-oriented programming, where autonomous agents, not statically programmed services, drive system behavior. In this new paradigm, agents are constructed from language models, structured prompts, memory layers, and external tools.

Exploring Reactive and Proactive Observability in the Modern Monitoring Landscape

Aggregated on: 2025-06-10 21:13:12

Introduction The modern digital world, with its complex web of microservices, containerized apps, and cloud-native systems, demands a rethinking of how we monitor and observe these environments. From the traditional monitoring systems, there is an evident shift to two main approaches that have emerged: Reactive and Proactive observability. What is Reactive and Proactive Observability? Organizations rely on metrics, logs, and traces to retroactively identify the underlying causes of issues, similar to treating an infection. Reactive observability is a conventional approach that examines system behavior after an incident has occurred. This reactive method requires organizations to have the necessary tools and expertise, which helps them detect symptoms and connect them to a solution that resolves the problem.

Event Sourcing Unpacked: The What, Why, and How

Aggregated on: 2025-06-10 15:13:11

A traditional system maintains its state consistent with respective business rules. When queried, this system provides its current state only i.e. where the system is, and no information about how it got there. A simple approach to track the systems’ state evolution (how it got there) is by maintaining history. However, this approach is limited to providing information about state changes only. Moreover, the record-keeping becomes burdened with process details and has to evolve with all the processes that affect the state change.

Data quality has shifted from a checkpoint to being an operational requirement. As more and more data warehouses become cloud-native, and the complexity of running real-time pipelines increases, data engineers face a non-trivial problem: how to operationalize quality checks without slowing down the velocity of the ETL workflows. “Traditional post-load checks or static rules” do not suffice. Automated validation and anomaly detection in cloud ETL pipelines need to be performed in a manner that adapts to evolving schemas, variable latency, and dynamic business logic. Why Reactive Data Quality Is No Longer Enough In the past, data quality was typically validated at the end of an ETL pipeline, often using standalone validation scripts or manual dashboards. This post-hoc approach worked reasonably well in static, batch-oriented data ecosystems. However, in modern cloud environments where data flows through event-driven, streaming, and micro-batch jobs, such passive controls introduce significant latency and operational risk. By the time an issue is detected — sometimes hours or even days later — the damage may already be done.

Mastering Accessibility in Web Development: A Developer’s Guide

Aggregated on: 2025-06-09 21:13:11

Introduction Accessibility (a11y) is not just a feature—it’s a necessity. According to the World Health Organization (WHO), more than 1 billion people globally have some form of disability. Ensuring that digital experiences are accessible allows everyone to use and benefit from web applications. Despite its importance, many developers overlook accessibility due to a lack of awareness or perceived complexity. In this article, we’ll break down key accessibility concepts, common issues, and best practices with practical examples, ensuring your web applications are inclusive and WCAG-compliant.

How You Can Use Few-Shot Learning In LLM Prompting To Improve Its Performance

Aggregated on: 2025-06-09 20:13:11

You must’ve noticed that large language models can sometimes generate information that seems plausible but isn't factually accurate. Providing more explicit instructions and context is one of the key ways to reduce such LLM hallucinations. That said, have you ever struggled to get an AI model to understand precisely what you want to achieve? Perhaps you've provided detailed instructions only to receive outputs that fall short of the mark?

Software Specs 2.0: Evolving Requirements for the AI Era (2025 Edition)

Any form of data that we can use to make decisions for writing code, be it requirements, specifications, user stories, and the like, must have certain qualities. In agile development, for example, we have the INVEST qualities. More specifically, a user story must be Independent of all others and Negotiable, i.e., not a specific contract for features. It must be Valuable (or vertical) and Estimable (to a good approximation). It must also be Small to fit within an iteration and Testable (in principle, even if there isn’t a test for it yet). This article goes beyond agile, waterfall, rapid application development, and the like. I will summarise a set of general and foundational qualities as a blueprint for software development.

Online Developer Tools a Backdoor to Security Threat

Aggregated on: 2025-06-09 18:13:11

Free Online Utilities May Not Be Safe Using online developer utilities, such as a JSON Viewer, can be incredibly convenient for parsing and visualizing JSON data, but they also come with significant risks. The tool, for instance, often requires users to upload JSON files or paste sensitive data directly into the tool. If the utility operates online without robust security measures, this data could be intercepted or stored without the user's knowledge, potentially exposing confidential information such as API keys, user credentials, or proprietary business logic. One major concern is the lack of transparency in how some online tools handle uploaded data. For example, if the JSON Viewer utility does not explicitly state that it deletes data after processing, there is a risk that the data could be retained on the server, making it vulnerable to breaches. Additionally, if the tool is hosted on an unsecured or compromised website, attackers could exploit it to inject malicious scripts or steal data.
