Once again, I am jumping into the pool’s deep end to learn a programming language. LangChain is a library that empowers developers to build applications using large language models (LLMs) and other computational resources. It makes managing interactions with language models accessible, chain together multiple components, and integrate additional resources, such as APIs and databases.

Here is a brief walkthrough of how LangChain works:

1. Components and Chains: LangChain has several core concepts. Components are the basic building blocks of LangChain. They are responsible for processing input data and generating output data. Chains are sequences of components that are executed in order.
2. Models: LangChain provides a generic interface to various foundation models. These models can be used for tasks such as question-answering, chatbots, and agents.
3. Prompts: LangChain provides a framework to help you manage your prompts. Prompts are the input data that is fed into your LangChain application.
4. Memory: LangChain provides a standard interface for memory, a collection of memory implementations, and examples of chains/agents that use memory.
5. Evaluation: Generative models are notoriously hard to evaluate with traditional metrics. One new way of evaluating them is using language models to do the evaluation.

The Langchain can be loaded quickly using my favorite tool Azure Data Studio Manage Packages.

Python should already be installed at this point.

I’ve selected five great sites for tutorials about Langchain:

1. GitHub – gkamradt/langchain-tutorials
2. Getting Started — ?? LangChain 0.0.187.
3. Getting Started with LangChain: A Beginner’s Guide to Building LLM
4. Tutorials — ?? LangChain 0.0.187.
5. LangChain: How to Use – Beginner’s Guide | Step-by-Step Tutorial.

LangChain is a game-changer in coding languages, offering developers an intuitive and efficient platform to build applications. With its blend of programming paradigms, LangChain empowers programmers to write clean, concise, and scalable code.

As LangChain continues to evolve, we can expect it to find its place among the leading coding languages, attracting developers with its power and ease of use. My journey begins here; how about you?

Why is the question of personal well-being and mental health always directed toward those in the technology field? What if a different kind of accident occurs? Individuals working in technology often face this inquiry from management and auditors who seek to assess departmental risks. Comprehensive plans are devised, explicitly detailing measures to restore systems and services in case of their absence. All these efforts are aimed at safeguarding and fortifying the business.

However, should we not also prioritize the well-being of the bus driver in our own career journeys? Who exactly is this bus driver? The bus driver can represent anyone who jeopardizes your career, job, or role. It emerges unexpectedly and catches you off guard. The consequences can be severe and widespread. These individuals can be found within your professional network. Are you equipped with the knowledge to evade them before they cause harm? I will share the invaluable lessons I’ve gathered while traversing the landscape of Technology.

Discover a fresh perspective on wellness and mental health tailored for individuals in the technology field.

You won’t always have access to the internet. YES, it’s true. Circumstances(outages) and bad WIFI often leave us grounded from the cloud. But there’s hope you to continue to stay creative and build in this space when you are offline called WSL(Windows Subsystem LINUX)

I am unsure what drew me into trying Python Libary files like a shopper in a warehouse store, but I wanted to try them all. Especially the ones that produce graphic displays. There is a little extra effort to do this in Ubuntu, but Azure Data Studio manages it seamlessly. Visualizations are the best way to tell a data story; I try to use them whenever possible. I like to keep it simple, so here is a sample code in Python using Azure Data Studio.

Prerequisites

Python

Azure Data Studios

Add matplotlib package to Azure Data Studio

Insert the following code into a Jupyter Notebook or directly in Azure Data Studio

import matplotlib.pyplot as plt

x = [1,1,2,3,3,5,5,7,8,9,10,

     10,11,11,13,13,15,16,17,18,18,

     18,19,20,21,21,23,24,24,25,25,

     25,25,26,26,26,27,27,27,27,27,

          ]

plt.hist(x, bins=10)

plt.show()
