Java NIO: OutOfMemoryError

Aggregated on: 2024-01-18 14:01:52

Java NIO (New Input/Output) is a high-performance networking and file-handling API that facilitates you to do non-blocking IO. Non-blocking I/O provides the following advantages: Concurrency: NIO enables handling multiple connections simultaneously without blocking threads, leading to better concurrency. Asynchronous programming: Asynchronous programming allows the application to perform other tasks while waiting for I/O operations to complete, improving overall efficiency. Performance: Non-blocking I/O can manage more connections with fewer threads, reducing the resources required for handling concurrent requests. One of our applications was leveraging this NIO; however, it suffered from frequent ‘java.lang.OutOfMemoryError: Direct buffer memory’ when we were running in Java 11. However, when we upgraded to Java 17 frequency of the occurrence of ‘java.lang.OutOfMemoryError: Direct buffer memory’ was reduced dramatically. In this post we would like to share our findings and resolution to fix this problem.

Developing With Dragonfly: Cache-Aside

Aggregated on: 2024-01-18 13:31:52

In the realm of web application development (or any other applications involving backend servers), the quest for optimal performance often intersects with the challenge of managing data retrieval efficiently. Imagine a scenario where a web application is tasked with fetching a large amount of data from its main database: user profiles, blog posts, product details, transaction history, and more. These queries to the primary database will inevitably introduce significant latency, resulting in a poor user experience and potentially pushing the database to its limits. A common solution is to add a cache that can relieve the primary database of much of the load. This cache mechanism operates as a strategic intermediary, positioned between the intricate network of services constituting your application and the primary database itself. Its fundamental purpose is to store a duplicate copy of the most frequently requested data or data anticipated to be accessed imminently.

The Role of Zero-Knowledge Proofs in LLM Chains for Data Privacy

Aggregated on: 2024-01-17 20:46:52

In today's digital age, data privacy has become a paramount concern for individuals and organizations alike. With the increasing amount of personal and sensitive information being stored and transmitted online, there is a growing need for robust security measures to protect this data from unauthorized access and misuse. One promising solution to address this challenge is the use of zero-knowledge proofs in large language model chains. What Are Zero-Knowledge Proofs? Zero-knowledge proofs are cryptographic protocols that allow one party (the prover) to prove to another party (the verifier) that a certain statement is true without revealing any additional information beyond the validity of the statement itself. In other words, zero-knowledge proofs enable the prover to convince the verifier of the truthfulness of a claim without disclosing any underlying data or secrets.

Enhancing GenAI Results With the Nearest Neighbor Algorithm

Aggregated on: 2024-01-17 16:01:52

Forget about artificial intelligence (AI) and all that fancy math for a moment. Let’s talk about cheese. Specifically when you are creating a charcuterie board. If you’re not familiar, the United State’s version of a charcuterie board is (literally) a board of wood or stone with a spread of meats, cheeses, and other tasty bits. If you’re doing it right, each meat on the board has been meticulously paired with a specific cheese to complement flavor, texture, and appearance (we eat with our eyes, you know). Creating a board is as much an art as it is a culinary delight. What makes one cheese better than another? What makes one board better than another? A few distinct characteristics can categorize all cheeses. And one can use these characteristics to craft the perfect board. You could even follow a theme like “cheddar,” “goat’s milk,” or “high-contrast.”

Simple SQL Statements Only Exist in Coursebooks and Training Courses

Aggregated on: 2024-01-17 15:46:52

The sample SQL statements in coursebooks are usually simple and easy to understand. They even read like English sentences, giving the impression that SQL is rather simple and easy to learn. Actually, such a SQL statement consisting of only a few lines of code can only be found in coursebooks and training courses. In real-world businesses, the amount of SQL code is measured by KB instead of the number of lines. One SQL statement having several hundred lines of code and N layers of nested subqueries often reaches 3KB to 5KB in size. Such SQL statements are not easy to learn at all but rather a nightmare even to professional programmers.

SQL Studio, Visually Designing your Database

Aggregated on: 2024-01-17 14:46:52

SQL Studio is one of the core components of Magic. One of its features is that it allows you to visually design your database. This significantly simplifies software development since it allows you to focus on "the what" instead of "the how." To illustrate the importance of the above point, try to write down the SQL statement required to create a database table in SQLite with an auto-increment primary key and two text columns. Chances are you cannot do it without searching. Software development as an art form contains too many constructs to be able to fit all of them into your head, which is a large part of the reason why low-code, no-code, and AI so drastically improve your productivity. Below is how you create a new column in SQL Studio.

Enhancing Resiliency: Implementing the Circuit Breaker Pattern for Strong Serverless Architecture on AWS

Aggregated on: 2024-01-16 20:31:51

Serverless architecture is a way of building and running applications without the need to manage infrastructure. You write your code, and the cloud provider handles the rest - provisioning, scaling, and maintenance. AWS offers various serverless services, with AWS Lambda being one of the most prominent. When we talk about "serverless," it doesn't mean servers are absent. Instead, the responsibility of server maintenance shifts from the user to the provider. This shift brings forth several benefits: Cost-efficiency: With serverless, you only pay for what you use. There's no idle capacity because billing is based on the actual amount of resources consumed by an application. Scalability: Serverless services automatically scale with the application's needs. As the number of requests for an application increases or decreases, the service seamlessly adjusts. Reduced operational overhead: Developers can focus purely on writing code and pushing updates, rather than worrying about server upkeep. Faster time to market: Without the need to manage infrastructure, development cycles are shorter, enabling more rapid deployment and iteration. Importance of Resiliency in Serverless Architecture As heavenly as serverless sounds, it isn't immune to failures. Resiliency is the ability of a system to handle and recover from faults, and it's vital in a serverless environment for a few reasons:

Rethinking Threat Detection and Response in Cloud-Native Ecosystems

Aggregated on: 2024-01-16 19:31:51

In highly dynamic cloud-native environments, the traditional Threat Detection and Response (TDR) approaches are increasingly showing their limitations. With its unique architecture and operational dynamics, Kubernetes demands re-evaluating how we handle security threats, particularly in the context of Endpoint Detection & Response (EDR) solutions. The Traditional EDR Approach: SIGKILL and Its Limitations Traditionally, EDR solutions have relied heavily on the Signal Kill (SIGKILL) command in Linux systems to terminate processes deemed malicious or risky. SIGKILL is an abrupt method that forcibly stops a process and its running threads, offering no chance for the process to complete any cleanup operations. While effective in terminating processes, this brute-force approach can lead to unintended consequences like data loss or corruption. It’s a method suited for systems where immediate cessation is paramount, but in the cloud-native world, such an approach can be too heavy-handed, particularly for mission-critical applications.

Securing Web User Interfaces of Cloudera Data Platform (CDP) Services via Apache Httpd Reverse Proxy

Aggregated on: 2024-01-16 17:31:51

It’s an HTTP Server built by Apache Foundation. HTTP Stands for Hypertext Transfer Protocol, which decodes Hypertext and Multimedia documents through a server-side program. An HTTP daemon (background process) program runs and serves the requests from any HTTP client like a Web Browser. It is important to note that Apache HTTP Server can only serve static content like text or media that doesn’t change during the web page loading. To serve the dynamic content via scripts technologies/protocols like Common Gateway Interface (CGI), Java Server Pages (JSP), etc. are being used. What Are Apache Modules? As stated above, Apache HTTP Server is a basic web server that can be used to serve non-dynamic content. Still, it also doesn’t provide any functionalities like Authentication, Encryption of requests, Logging, Support, SSL, Heartbeat, LDAP, Caching, etc. So, it provides special program modules to extend the core Apache HTTP Server's functionality.

What Our Tests Don’t Like About Our Code

Aggregated on: 2024-01-16 16:01:51

When you start writing tests for your code, you'll likely have the feeling — bloody hell, how do I drag this thing into a test? There is code that tests clearly like and code they don't. Apart from checking the correctness of our code, tests also give us hints about how to write it. And it's a good idea to listen. A test executes your code in the simplest possible setting, independent of the larger system it's part of. But if the simplest possible setting is how it's run in our app, and it's impossible to tease out the individual pieces — that's a bad sign. If we're saying — nah, we don't need tests. All the code is already executed in the app — that's a sign that we've created a large slab that is hard to change and maintain. As Uncle Bob put it: "Another word for testable is decoupled."
