How To Convert ODF Files to PDF in Java

Aggregated on: 2023-11-06 20:33:31

When the time comes to pick and download a suite of office applications, we can expect that the MS Office suite will dominate the conversation. Each application included in the MS Office package comes equipped with dozens of powerful, intuitive features, and all the OpenXML file formats – .DOCX, .XLSX, PPTX, etc. – can shoulder the burden of immense, data-intensive edits and developer customizations while retaining a relatively small file size through efficient compartmentalization and lossless compression. However, OpenXML files aren’t the only ones represented in XML and zipped into convenient lossless file containers. The Apache OpenOffice suite – which originated in 2006, right around the timeframe when OpenXML format became standard for MS Office files – also offers XML-based file structure with lossless Zip compression, and this option makes for a nice alternative to OpenXML files when cost considerations come into play.

Limited Conversations With Distributed Systems

Aggregated on: 2023-11-03 18:03:30

By the way, ChatGPT suggested the title: The Art of Balancing Control and Accessibility Background Houston Airport had this really big problem. Passengers complained about the time it took for luggage to arrive at the terminal building after the airplane had landed. The Airport invested millions to solve this pain point. They improved the process, hired more people, and introduced new technology. They eventually succeeded in reducing the wait time to 7 minutes. However, users still complained. The Airport realized that they had reached a point where optimizing the process/design was no longer optimal. So they did something different. They reframed the problem. By reframing the problem, they discovered that it was not the time it took to get the luggage to the terminal building that was the problem. It was the time the passengers had to wait for the luggage that was the problem. The Airport decided to park the airplanes further away from the terminal building. Consequently, it took some time for passengers to arrive at the terminal building, thus reducing the wait time for luggage, and voila! Complaints dropped drastically.

Domain-Driven Design: Why Do Companies Need This Approach, Who Uses It, and What Is Its Essence?

Aggregated on: 2023-11-03 16:48:30

Building software that meets the needs and expectations of businesses and users in a dynamic and ever-changing technological world can be challenging. Software companies gradually require a workable way to make communication between the business and the product team more transparent. The domain-driven design (DDD) approach helps to solve this problem by fostering a profound understanding of the subject matter and continuous collaboration between developers and business experts. In fact, developers gain a more in-depth understanding of the underlying domain and business rules through constant communication. At the same time, stakeholders gain a better understanding of technical capabilities and constraints. For example, Standish Group’s analysis of 100 projects found that 70% of rework was due to a lack of domain knowledge during the requirements and design phases, confirming that DDD fosters understanding between businesses and developers.

Architecture Patterns: The Circuit-Breaker

Aggregated on: 2023-11-03 11:03:30

In the world of distributed systems, the likelihood of components failing or becoming unresponsive is higher compared to monolithic systems. Given the interdependence of microservices or modules in a distributed setup, the failure of one component can lead to cascading failures throughout the system, potentially causing the entire system to malfunction or shut down. Therefore, resilience — the ability of a system to handle and recover from failures — becomes critically important in distributed environments. Much like how an electrical circuit breaker prevents an overload by stopping the flow of electricity when excessive current is detected, the Circuit Breaker pattern in software engineering stops the flow of requests to a service when the number of failures exceeds a predefined threshold. This ensures that a failing service doesn’t continue receiving traffic until it recovers, preventing further strain and potential cascading failures.

How to Reduce LLM Hallucination

Aggregated on: 2023-11-02 20:03:29

LLM hallucination refers to the phenomenon where large language models like chatbots or computer vision systems generate nonsensical or inaccurate outputs that do not conform to real patterns or objects. These false AI outputs stem from various factors. Overfitting to limited or skewed training data is a major culprit. High model complexity also contributes, enabling the AI to perceive correlations that don't exist. Major companies developing generative AI systems are taking steps to address the problem of AI hallucinations, though some experts believe removing false outputs entirely may not be possible.

I recently attended my second All Things Open conference and wanted to share some of the observations, experiences, and lessons I learned along the way. As conferences go, All Things Open stands out to me for a few reasons. Hosted at the Raleigh Convention Center in North Carolina, it’s one of the few larger shows that doesn’t sit in a wallet-busting city. And, at ~5,000 attendees, it’s definitely one of the more significant events, standing out from events like DevOpsDays, BSides, and even Monitorama, which attract much more modest crowds. And, of course, it stands out because of its focus. While every event — from the aforementioned DevOpsDays all the way up to the monster conferences like Cisco Live, VMware Explore, and re:Invent — contain an acknowledgment of the importance of open source tools, none of those events are so wholly and wholesomely focused on the tools, techniques, and community that make open source the powerful force for good that it is.

In today's tech landscape, where application systems are numerous and complex, real-time monitoring during deployments has transitioned from being a luxury to an absolute necessity. Ensuring that all the components of an application are functioning as expected during and immediately after deployment while also keeping an eye on essential application metrics is paramount to the health and functionality of any software application. This is where Datadog steps in — a leading monitoring and analytics platform that brings visibility into every part of the infrastructure, from front-end apps to the underlying hardware. In tandem with this is Ansible, a robust tool for automation, particularly in deployment and configuration management. In this article, we will discover how Datadog real-time monitoring can be integrated into Ansible-based deployments and how this integration can be leveraged during deployments. This concept and methodology can be applied to similar sets of monitoring and deployment tools as well. Why Integrate Real-Time Monitoring in Deployments? In the ever-evolving realm of DevOps, the line between development and operations is continuously blurring. This integration drives a growing need for continuous oversight throughout the entire lifecycle of an application, not just post-deployment. Here's why integrating Datadog with your deployment processes and within your deployment scripts is both timely and essential:

Aggregated on: 2023-11-02 17:48:29

At Octomind, we are using Large Language Models (LLMs) to interact with web app UIs and extract test case steps that we want to generate. We use the LangChain library to build interaction chains with LLMs. The LLM receives a task prompt, and we, as developers, provide tools the model can utilize to solve the task. The unpredictable and non-deterministic nature of the LLM output makes ensuring type safety quite a challenge. LangChain's approach to parsing input and handling errors often leads to unexpected and inconsistent outcomes within the type system. I’d like to share what I learned about parsing and error handling of LangChain.
