Perils of Partitioning

|

Partitioning is one of the easiest ways to improve the performance of your data lake, because it reduces the amount of data scanned. But implementing partitions can be surprisingly challenging, as can their effective use. In this post I look at several of the issues that you should consider when partitioning your data.

Large Language Model (LLM) Coding Assistance

|

Note: It has been about three months since this was originally written, so there is a certain amount of information that is out of date. See the addendum for updated information. With all the hype surrounding Generative AI/LLM, and all the hallucinations mentioned in the news, what are these actually good for? As it turns out LLMs trained for code generation are helpful. But what if you don’t want your code going to some cloud provider? The following is a…

In this blog post I walk through the process of aggregating CloudTrail data using SQL.

From RAGs to Riches – Adding Context to Your LLM

|

In my previous post, Experiences in Fine-Tuning LLMs: Time + Power = Potato?, I covered my experiences around trying to fine-tune an LLM (large language model) with a dataset, which gave me less than stellar results. Ultimately, fine-tuning is best for a use-case where additional reasoning & logic needs to be added to an LLM, but it’s subpar for adding information. However, if you’re trying to get an LLM to answer questions using your data, then retrieval augmented generation (RAG)…

Experiences in Fine-Tuning LLMs: Time + Power = Potato?

|

Embarking on the journey to fine-tune large language models (LLMs) can often feel like setting sail into uncharted waters, armed with hope and a map of best practices. Yet, despite meticulous planning and execution, the quest for improved performance doesn’t always lead to the treasure trove of success one might anticipate. And I know you may be wondering how potatoes come into play here, but I promise that we’ll get to it. From the challenges of data scarcity to resource…
