In this article, we will learn how memory usage patterns can affect the real-time performance of an embedded application, drawing from a recent experience tracing an audio DSP application running on an embedded Linux platform. First, I will introduce the product in question and the real-time audio software I developed for it. Then, I’ll describe the issues I encountered with audio callbacks and the strategy I followed to determine the cause of the issues, ending with my solution and lessons learned.

To say that site uptime vendors deliver notifications is about as insightful as saying that cars have steering wheels, planes have wings, or TikTok videos have cringe. It’s a given. But this doesn’t mean that all vendors use the same notification playbook. Some vendors offer basic (read: superficial) notification features, while others offer advanced notification features.

In a previous post, we described a CSTR and a PID controller. This post will cover the code and architecture of the digital twin from this project repo. The project leverages Kafka for data streaming, Faust for data processing, InfluxDB for storing the time series data, and Telegraf for writing data from the topic to InfluxDB. We’ll also cover the advantages and disadvantages of this stack.

If you’ve ever worked with Apache Kafka, you know that it’s a powerful tool, but it can also be a bit finicky. Things can go wrong, and when they do, it’s important to know how to troubleshoot and resolve those issues quickly. Over the years, I’ve encountered my fair share of Kafka errors—some that had me scratching my head for days and others that were relatively straightforward once I knew what to look for.

Data aggregation includes systematically collecting, transforming, and summarizing raw data from multiple sources. A unified, consistent view helps IT teams analyze vast amounts of information, uncover patterns, and derive actionable insights for informed decision-making. In our case, it’s all about enhancing incident management.

The IT job market has become a hot topic of conversation. With technology evolving at lightning speed and the job market shifting in response, it's more important than ever to understand the current landscape. Is the IT job market strong, or is it on the verge of a crisis?

SaaS services are one of the biggest drivers of OpEx (operating expenses) for modern businesses. With Gartner projecting $247.2 billion in global SaaS spending this year, it’s no wonder SaaS budgets are a big deal in the world of finance and IT. Efficient SaaS utilization can significantly affect both the bottom line and employee productivity.

Elasticsearch is primarily a search engine optimized for fast, complex search queries, especially text searches, and is often used for log and event data analysis. MongoDB, on the other hand, is a general-purpose, document-oriented database that excels in storing and retrieving structured and semi-structured data. It is commonly used for mobile, social, and IoT applications. While Elasticsearch provides superior search capabilities, MongoDB offers more robust data processing and storage features.
