Observability for Browsers

Aggregated on: 2024-10-09 23:06:27

Browser agents are essential tools for monitoring and observability in modern web applications, especially with the increasing complexity of both Single Page Applications (SPAs) and traditional multi-page sites. A browser agent operates within a user’s browser, collecting data on performance metrics, errors, user interactions, and network requests, providing real-time insights into the application’s behavior. For SPAs, browser agents face unique challenges due to the dynamic nature of page transitions, which occur without full reloads. This makes tracking performance metrics, memory leaks, and state changes over time more complex, as data needs to persist and update continuously without the typical page lifecycle events seen in multi-page applications. Conversely, in traditional multi-page websites, challenges arise around data loss due to ephemeral web pages, where navigating away from a page could result in the loss of unsent data.

Microservice Proliferation: Too Many Microservices

Aggregated on: 2024-10-09 22:06:27

Microservices architecture promotes the development of applications, as suites of small, independent, loosely coupled services. Because of its numerous advantages (e.g., scalability, reliability, faster development cycles, easier maintenance of individual services, etc., detailed in this article), it has gained significant traction in the software industry lately and organizations are building their applications following microservices architecture. However, it comes with a few pitfalls as well. Recently while working on a use case at work, I observed the other side of microservices architecture, i.e., microservices proliferation. This article is an attempt to detail the pitfalls associated with the excessive creation of microservices (microservices proliferation), offering insights on their causes, implications, and potential strategies for mitigation.

The Importance Of Verifying Your GitHub Environment’s Security Controls

Aggregated on: 2024-10-09 21:06:27

Security is a top priority of every company. It’s not surprising: source code, the most critical asset of any organization, should be under reliable protection — especially in view of constantly rising threats. Ransomware, infrastructure outages, vulnerabilities, and other threats can strike your GitHub repository at any time. Organizations, especially those that operate in the most regulated industries, can face a few main challenges regarding their GitHub data protection. The first one, we have already mentioned — it’s the value of the data stored in the repositories. The second one is their ability to forecast any event of failure and take proactive measures to make sure that their data is available and recoverable in any event of failure.

Welcome to the second part, where we discuss another well-known parameter, "Top-P."

Modify JSON Data in Postgres and Hibernate 6

Aggregated on: 2024-10-09 18:06:27

This is another article in the series related to supporting the Postgres JSON functions in a project using the Hibernate framework with version 6. The topic for the article is modification operations on JSON records. As in the previous article, it is worth mentioning that Postgres might now have such comprehensive operations as other NoSQL databases like MongoDB for JSON modification (although, with the proper function constructions, it is possible to achieve the same effect). It still suits most projects that require JSON modification. Plus, with transaction support (not support in a NoSQL database at such a level), it is a pretty good idea to use Postgres with JSON data. Of course, NoSQL databases have other benefits that might suit better projects. There are generally many articles on Postgres' support for JSON. This article focuses on integrating this support with the Hibernate 6 library.

Being the Glue: Managing a Zero-to-One Software Project Across Multiple Teams

Aggregated on: 2024-10-09 17:06:27

In software engineering, the role of a “Glue” is vital yet often overlooked. This term refers to the person who connects various teams, ensuring that a complex project with many moving parts comes together seamlessly. If you’re leading a zero-to-one software project that spans more than a couple of teams, your role as the Glue becomes even more critical. This article explores strategies for managing team dependencies, scheduling demos, building alignments, and adapting to pivots while maintaining focus on user needs. 1. Managing Team Dependencies When working across multiple teams, managing dependencies is one of the biggest challenges. Each team might have its own goals, timelines, and constraints, which can create friction if not carefully coordinated. Here’s how to effectively manage these dependencies:

Introducing the New Dapr Jobs API and Scheduler Service

Aggregated on: 2024-10-09 15:06:26

The Dapr 1.14 release last month included many new capabilities and was feature-packed. This included the addition of a new Jobs API and Scheduler control plane service for managing jobs. Over the years, the Dapr project was often requested to include a Jobs API. The Scheduler service enables this and is designed to address the performance and scalability improvements on Actor reminders and the Workflow API. In this post, I am going to deep dive into the details of how the Scheduler service was designed and its implementation to give you some background. Prior to v1.14 if you wanted to schedule a job, you could use the Cron binding component to implement recurring jobs on a regular defined schedule; for example, automating database backups, sending out recurring email notifications, running routine maintenance tasks, data processing, and ETL, running system updates and batch processing. However, the binding approach lacked in the areas of durability and scalability, and more importantly, could not be combined with other Dapr APIs. For example, another frequent request is to be able to have delayed messages for pub/sub, and there will undoubtedly be other delayed job scenarios that will emerge.

Optimizing IoT Performance in Industrial Environments

Aggregated on: 2024-10-09 14:06:26

Internet of Things (IoT) devices have become common in industrial environments, giving users better visibility, control, and capabilities. However, making the IoT product work well requires knowing how to optimize software and hardware-related aspects. 1. Ensure the IoT Device Has Adequate Hardware People must first consider how they will use the IoT device and then evaluate whether it has the appropriate hardware capabilities to meet relevant current and future needs. A good starting point is to examine the storage, memory, and processing performance and verify that it aligns with the proposed use cases.

The Art of Full Stack Debugging

Aggregated on: 2024-10-09 13:06:26

Full stack development is often likened to an intricate balancing act, where developers are expected to juggle multiple responsibilities across the front end, back end, database, and beyond. As the definition of full-stack development continues to evolve, so too does the approach to debugging. Full stack debugging is an essential skill for developers, as it involves tracking issues through multiple layers of an application, often navigating domains where one’s knowledge may only be cursory. In this blog post, I aim to explore the nuances of full-stack debugging, offering practical tips and insights for developers navigating the complex web of modern software development. Notice that this is an introductory post focusing mostly on the front-end debugging aspects. In the following posts, I will dig deeper into the less familiar capabilities of front-end debugging.

Redefining Java Object Equality

Aggregated on: 2024-10-08 23:06:26

Equality in Java Object equality is often a hot topic for assessing concepts and one of the pillars (the other is- hashCode()) of how many of the implementations of Collection Frameworks work. We check equality by providing our own implementation for the method public booleanjava.lang.Object#equals(java.lang.Object other). According to Oracle documentation, the following mandates should be adhered to: It is reflexive: For any non-null reference value x, x.equals(x) should return true. It is symmetric: For any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true. It is transitive: For any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true. It is consistent: For any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects are modified. For any non-null reference value x, x.equals(null) should return false. Please note that there exist a few more related to using it along with hashCode(), but we do not discuss them here for brevity, assuming the readers are already aware of them.

Starting to Care About Security

Understanding the Differences Between Rate Limiting, Debouncing, and Throttling

Aggregated on: 2024-10-08 19:06:26

When developing, we often encounter rate limiting, debouncing, and throttling concepts, such as debouncing and throttling in the front end with event listeners and rate limiting when working with third-party APIs. These three concepts are at the core of any queueing system, enabling us to configure the frequency at which functions must be invoked over a given period. While this definition sounds simple, the distinction between the three approaches can take time to grasp. If my Inngest function is calling the OpenAI API, should I use rate limiting or throttling? Similarly, should I use debouncing or rate limiting if my Inngest Function is performing some costly operation?

PostgreSQL Everywhere and for Everything

Aggregated on: 2024-10-08 18:06:26

PostgreSQL is one of the most popular SQL databases. It’s a go-to database for many projects dealing with Online Transaction Processing systems. However, PostgreSQL is much more versatile and can successfully handle less popular SQL scenarios and workflows that don’t use SQL at all. In this blog post, we’ll see other scenarios where PostgreSQL shines and will explain how to use it in these cases. How It All Started Historically, we focused on two distinct database workflows: Online Transaction Processing (OLTP) and Online Analytical Processing (OLAP).

Aggregated on: 2024-10-08 17:06:26

The time for rapid technology development and cloud computing is perhaps the most sensitive time when security issues are of great importance. It is here that security will have to be injected into a process right from the beginning — be it software development or cloud infrastructure deployment. Two concepts that are very influential in doing so are CSPM and DevSecOps. Don't worry if these terms seem complicated — all they really mean is the inclusion of security within how companies build and manage their cloud environments and software pipelines.

Jenkins in the Age of Kubernetes: Strengths, Weaknesses, and Its Future in CI/CD

Aggregated on: 2024-10-08 16:06:26

What Is Jenkins, and Why Does It Matter? In the world of software development, speed and efficiency are everything. That's where Jenkins, a popular open-source automation server, steps in. Jenkins plays a key role in streamlining workflows by automating the building, testing, and deployment of code — tasks that would otherwise take up countless developer hours. But why does Jenkins matter in the larger context of DevOps and CI/CD (Continuous Integration/Continuous Deployment)? Well, if you're part of a development team, you're likely familiar with these terms. DevOps aims to break down barriers between development and operations teams, enabling faster, more reliable software releases. CI/CD pipelines, in turn, automate the process of integrating new code and delivering updates to users, minimizing downtime and reducing errors.

Secret Management and Rotation

Aggregated on: 2024-10-08 15:06:26

Secrets are the keys to manage and enhance the security of a software application. Secret keys play a pivotal role in the authentication, authorization, encryption/decryption, etc. of data flowing through the application. There are various types of secrets and few of them are: Encryption/Decryption keys: Keys to encrypt/decrypt data at various levels; e.g., REST, database, etc. API keys: Keys to provide access to an exposed API Credentials: Keys to provide credentials; e.g., database connection strings SSH keys: Keys to provide SSH communication to server Passwords: Keys to store passwords It is very important to store these keys and ensure safety of the stored keys. A compromised key could lead to data leak, system compromise, etc., and to raise the security bar, it is required to ensure the secrets' rotation and expiry. A manual secret rotation is cumbersome and challenging problem to solve. In this post, I will discuss about implementing an automated key rotation for AWS Secrets Manager.

Aggregated on: 2024-10-08 14:06:26

Data integration is a hard challenge in every enterprise. Batch processing and Reverse ETL are common practices in a data warehouse, data lake, or lakehouse. Data inconsistency, high compute costs, and stale information are the consequences. This blog post introduces a new design pattern to solve these problems: the Shift Left Architecture enables a data mesh with real-time data products to unify transactional and analytical workloads with Apache Kafka, Flink, and Iceberg. Consistent information is handled with streaming processing or ingested into Snowflake, Databricks, Google BigQuery, or any other analytics/AI platform to increase flexibility, reduce cost, and enable a data-driven company culture with faster time-to-market building innovative software applications. Data Products: The Foundation of a Data Mesh A data product is a crucial concept in the context of a data mesh that represents a shift from traditional centralized data management to a decentralized approach.

What Is a Performance Engineer and How to Become One: Part 1

Aggregated on: 2024-10-08 13:06:26

Nowadays, many performance testers with many years of experience in IT have a lot of confusion and are still confused about the technologies they worked with and were used in their projects for years. A performance engineer is actually a professional performance testing and engineering expert with in-depth knowledge of many load-testing tools like LoadRunner, JMeter, Neoload, Gatling, K6, etc., and must have extensive experience in specialized skills. Most performance engineers have spent years submitting RFPs, developing scripts, executions, analysis, monitoring and tuning, and researching their specific projects/product domains and have gained a very high level of expertise in it. Performance engineers use the mastery of their experience to provide observations and recommendations with appropriate fixes that will improve the performance of private and public companies/stakeholders with many business requirements they work. They help them to resolve issues, blockers, and everything that will help to improve application/system performance to meet SLAs, and challenges and advance business interests. Performance engineers can work in all fields, cutting-edge technologies like Java, Python, IoT, cloud, blockchain, microservices, SAP, AI, Salesforce, etc., and domains that are likely to be more in demand in fast-developing sectors like BFSI, healthcare, e-commerce, insurance, and many more. Performance testing and engineering have become challenging for any performance guru when they use new technologies every time and all of us with many years of experience will have to spend lots of time. For example, if we are adding a new cloud to the existing architecture or doing performance testing for an SAP application or microservices application with the Go language, working on new technologies for measuring performance on migration and new domains may require you to put in months of formal study, do POCs, acquire advanced/best practices and expert opinions, participate in continuous learning, and gain extensive experience actually to test and fix performance.

Enhanced API Security: Fine-Grained Access Control Using OPA and Kong Gateway

Aggregated on: 2024-10-04 16:51:24

Kong Gateway is an open-source API gateway that ensures only the right requests get in while managing security, rate limiting, logging, and more. OPA (Open Policy Agent) is an open-source policy engine that takes control of your security and access decisions. Think of it as the mind that decouples policy enforcement from your app, so your services don’t need to stress about enforcing rules. Instead, OPA does the thinking with its Rego language, evaluating policies across APIs, microservices, or even Kubernetes. It’s flexible, and secure, and makes updating policies a breeze. OPA works by evaluating three key things: input (real-time data like requests), data (external info like user roles), and policy (the logic in Rego that decides whether to "allow" or "deny"). Together, these components allow OPA to keep your security game strong while keeping things simple and consistent. What Are We Seeking to Accomplish or Resolve? Oftentimes, the data in OPA is like a steady old friend — static or slowly changing. It’s used alongside the ever-changing input data to make smart decisions. But, imagine a system with a sprawling web of microservices, tons of users, and a massive database like PostgreSQL. This system handles a high volume of transactions every second and needs to keep up its speed and throughput without breaking a sweat.

How to Create a Search Engine and Algorithm With ClickHouse and Snowflake

Aggregated on: 2024-10-03 20:06:23

ClickHouse is an open-source data warehousing solution that is architected as a columnar database management system. This makes it extremely powerful to work with massive datasets, especially ones that are long as they can be aggregated, ordered, or computed with low latency. When working with the same data type, it's very efficient for fast scanning and filtering of the data. This makes it a great use case for implementing a search engine. A lot of applications use Elasticsearch as their search engine solution. However, such an implementation can be expensive both in terms of cost and time. Copying the data over to Elasticsearch can also cause lags because data is being migrated to another data store. Also, setting up the Elasticsearch cluster, configuring the nodes and defining and fine-tuning indexes can take more programmatic work, which may not be justified for all projects.

Implementing Polling With RxJS

Aggregated on: 2024-10-03 18:06:23

In most front-end applications, fetching data from the back-end is a common requirement to provide up-to-date information to the user. Typically, this process is straightforward: know the API endpoint, create a function, call it, process the response, and display it on the page. However, there are scenarios — often rare or specific to certain business needs — where client-server communication must be more sophisticated. In this article, we’ll explore one such case: implementing repetitive API calls (polling) using RxJS. RxJS Refresher Before diving into polling, let’s take a moment to refresh our understanding of RxJS. For those new to it, RxJS (Reactive Extensions for JavaScript) is a library that brings reactive programming concepts into the JavaScript ecosystem. It’s particularly useful for managing asynchronous operations, offering powerful tools like Observables, Observers, Subjects, and Operators.

AWS LetsEncrypt Lambda or Why I Wrote a Custom TLS Provider for AWS Using OpenTofu and Go

Aggregated on: 2024-10-02 17:36:22

These days, it's challenging to imagine systems that have public API endpoints without TLS certificate protection. There are several ways to issue certificates: Paid wildcard certificates that can be bought from any big TLS provider Paid root certificates that sign all downstream certificates that are issued by corporate PKI systems Free certificates issued by TLS providers like LetsEncrypt or AWS Certificate Manager Self-signed certificates, issued by OpenSSL or another tool Within the context of this post, I will mainly discuss free certificates that can be used inside of AWS, but not only by AWS services. Clearly, using anything other than AWS Certificate Manager makes no sense if you exclusively use managed AWS services and don't have strict security requirements. AWS Certificate Manager offers a very convenient and speedy method of issuing certificates via DNS or HTTP challenges; however, you face basic AWS limitations if you need to use these certificates outside of AWS services (API Gateway, ALB, NLB, etc.), such as an EC2 instance running Nginx that needs a physical certificate file. Additionally, even if you request it, AWS Certificate Manager does not display the certificate content.

Misconfiguration Madness: Thwarting Common Vulnerabilities in the Financial Sector

Aggregated on: 2024-10-02 15:21:22

Ever since people started putting their money into banks and financial institutions, other people have sought to steal those deposits or otherwise fraudulently obtain those protected assets. When someone asked infamous 1920s-era bank robber Willie Sutton why he robbed banks, he simply replied, “Because that’s where the money is.” Today, much of the money held by banks and other financial institutions is in digital form, and many of the sensitive records held by those firms can be just as valuable as the digital currency itself. But the reasons behind the targeting of financial institutions by threat actors remain much the same as they were in Sutton’s time over 100 years ago: that’s where the money — and at least some valuable personal data — is kept.
