As we have already seen with the basic components (Part 1, Part 2), the Hadoop ecosystem is constantly evolving and being optimized for new applications. As a result, various tools and technologies have developed over time that make Hadoop more powerful and even more widely applicable. As a result, it goes beyond the pure HDFS […]

GenAI systems affect how we work. This general notion is well known. However, we are still unaware of the exact impact of GenAI. For example, how much do these tools affect our work? Do they have a larger impact on certain tasks? What does this mean for us in our daily work? To answer these

Creating efficient prompts for large language models often starts as a simple task… but it doesn’t always stay that way. Initially, following basic best practices seems sufficient: adopt the persona of a specialist, write clear instructions, require a specific response format, and include a few relevant examples. But as requirements multiply, contradictions emerge, and even
This is Part 2 of an exploration into the unexpected quirks of programming the Raspberry Pi Pico PIO with Micropython. If you missed Part 1, we uncovered four Wats that challenge assumptions about register count, instruction slots, the behavior of pull noblock, and smart yet cheap hardware. Now, we continue our journey toward crafting a

Ten years ago, everybody was fascinated by the cloud. It was the new thing, and companies that adopted it rapidly saw tremendous growth. Salesforce, for example, positioned itself as a pioneer of this technology and saw great wins. The tides are turning though. As much as cloud providers still proclaim that they’re the most cost-effective

Staying on top of a fast-growing research field is never easy. I face this challenge firsthand as a practitioner in Physics-Informed Neural Networks (PINNs). New papers, be they algorithmic advancements or cutting-edge applications, are published at an accelerating pace by both academia and industry. While it is exciting to see this rapid development, it inevitably
In recent years, Parquet has become a standard format for data storage in Big Data ecosystems. Its column-oriented format offers several advantages: Faster query execution when only a subset of columns is being processed Quick calculation of statistics across all data Reduced storage volume thanks to efficient compression When combined with storage frameworks like Delta

Poetry is often seen as a pure art form, ranging from the rigid structure of a haiku to the fluid, unconstrained nature of free-verse poetry. In analysing these works, though, to what extent can mathematics and Data Analysis be used to glean meaning from this free-flowing literature? Of course, rhetoric can be analysed, references can

Now that we’ve explored Hadoop’s role and relevance, it’s time to show you how it works under the hood and how you can start working with it. To start, we are breaking down Hadoop’s core components — HDFS for storage, MapReduce for processing, YARN for resource management, and more. Then, we’ll guide you through installing

LoRA (Low Rank Adaptation – arxiv.org/abs/2106.09685) is a popular technique for fine-tuning Large Language Models (LLMs) on the cheap. But 2024 has seen an explosion of new parameter-efficient fine-tuning techniques, an alphabet soup of LoRA alternatives: SVF, SVFT, MiLoRA, PiSSA, LoRA-XS … And most are based on a matrix technique I like a lot: the
