The Cost Crisis in Observability Tooling

Aggregated on: 2024-02-22 17:12:05

The cost of services is on everybody’s mind right now, with interest rates rising, economic growth slowing, and organizational budgets increasingly feeling the pinch. But I hear a special edge in people’s voices when it comes to their observability bill, and I don’t think it’s just about the cost of goods sold. I think it’s because people are beginning to correctly intuit that the value they get out of their tooling has become radically decoupled from the price they are paying. In the happiest cases, the price you pay for your tools is “merely” rising at a rate several times faster than the value you get out of them. But that’s actually the best-case scenario. For an alarming number of people, the value they get actually decreases as their bill goes up.

Safe Clones With Ansible

Aggregated on: 2024-02-22 03:17:13

I started research for an article on how to add a honeytrap to a GitHub repo. The idea behind a honeypot weakness is that a hacker will follow through on it and make his/her presence known in the process. My plan was to place a GitHub personal access token in an Ansible vault protected by a weak password. Should an attacker crack the password and use the token to clone the private repository, a webhook should have triggered and mailed a notification that the honeypot repo has been cloned and the password cracked.

Unleashing the Power of Git Bisect

Aggregated on: 2024-02-22 02:47:13

We don't usually think of Git as a debugging tool. Surprisingly, Git shines not just as a version control system, but also as a potent debugging ally when dealing with the tricky matter of regressions. The Essence of Debugging with Git Before we tap into the advanced aspects of git bisect, it's essential to understand its foundational premise. Git is known for tracking changes and managing code history, but the git bisect tool is a hidden gem for regression detection. Regressions are distinct from generic bugs. They signify a backward step in functionality—where something that once worked flawlessly now fails. Pinpointing the exact change causing a regression can be akin to finding a needle in a haystack, particularly in extensive codebases with long commit histories.

The Impact of Technical Ignorance

Aggregated on: 2024-02-21 15:47:13

I knew a Chief Software Architect from a major financial organization who was an anomaly: he had never developed software professionally. His undergraduate degree is in Accounting and Finance, and his most hands-on technology role was as a DBA. [His LinkedIn profile lists an early Programmer role, though he insisted he didn’t.] Even so, he was well-respected within his organization for his thought leadership and solutions, but nevertheless, it seemed an unusual career path. Since I last worked with him, he has moved into C-level roles at other organizations, confirming his abilities as a technology leader. Then I thought of others I have worked with who are non-technical but positioned to impact technical direction and realized their lack of understanding impacted (and continues to impact) the quality of the software solutions we, as engineers, are expected to deliver.

How To Integrate NCache With JPA Hibernate for Caching in Spring Boot Applications

Aggregated on: 2024-02-20 15:32:12

What Is JPA Hibernate? Hibernate is one of the most popular Object Relational Mapper (ORM) libraries for Java and Spring applications. It helps developers connect to and work with relational databases from Java applications without having to write SQL queries. The library implements the JPA (Java Persistence API) specification and provides several additional features that help develop persistence in applications faster and easier. Caching in JPA Hibernate One of the cool features supported by Hibernate is caching. Hibernate supports two levels of caching — L1 and L2. L1 cache is enabled by default and works within an application scope, so it cannot be shared across multiple threads. For example, if you have a scaled microservice application that reads and writes to a table in a relational database setup, this L1 cache is maintained individually within each of these containers where the microservice is running.

Data Mesh: A Paradigm Shift in Data Management

Aggregated on: 2024-02-20 15:02:12

In this article, I’m going to share my thoughts about Data Mesh, the concept I came across a few years back. It was first introduced in 2018 at a conference called "Building Scalable and Reliable Data Products" by Zhamak Dehghani. A concept based on Domain Driven Design from the Book “Domain-Driven Design: Tackling Complexity in the Heart of Software” by Eric Evans. Data mesh is a new technology that could provide a framework for managing distributed data ecosystems more effectively by treating data as a product and empowering teams to take ownership of their data, while also enabling effective communication to interconnect distributed data residing in different locations. And by effective communication, I meant building a solid linkage between the data domains for proper data availability. I’m into the Analytics data world, currently, using Data Lake and its predecessor Data Warehouse. These are today’s data platform architectures to support businesses with Data Science, Data Analytics, and Business Intelligence solutions respectively. Let me first begin with what Analytical Data means, unlike Operational/ Transaction data, Analytics data is an aggregated view of the business data over time, modeled using business rules to provide insights and patterns to make business decisions. However, useful and quality insights and opportunities for businesses can be achieved only by using the data efficiently. The world today is generating a massive amount of data and with the rise of cloud computing, microservices architecture, and other modern technologies, data is becoming more complex to be handled by a single central data team as well as increasingly distributed across different systems and teams creating more silos, which is making it difficult to be managed and integrated as efficiently as possible. This is where Data Mesh is gaining popularity in the data management and data engineering community.

Recover Distributed Transactions in MySQL

Aggregated on: 2024-02-19 18:02:12

Distributed transactions, also known as XA transactions, emerged to address the complexity of coordinating transactions across multiple databases or systems in a distributed environment. Imagine you’re conducting an orchestra where each musician represents a different database or service. Just like ensuring harmony in music requires precise coordination, maintaining transactional integrity across distributed systems demands careful orchestration. This is where a two-phase commit (2PC), a vital aspect of XA transactions, steps in. 2PC acts as the conductor, ensuring that all musicians (or database participants) are ready to commit before the final note is played. Just as every instrument must be in tune before a symphony reaches its crescendo, 2PC ensures that all components of a distributed transaction are in sync before proceeding, thus guaranteeing the integrity of the transaction across the distributed landscape.
