A Few Moving Tips

Personal device upgrades have always been an exciting journey and, of course, a challenge. Software reinstallation, moving your local projects, and interface compatibility were a thrilling personal challenge that may take months of joy and loss. Cloud services drastically changed the game and left little room for novelty - you

Generative AI

AI generative fill still sucks

I wanted to upload a new image to my LinkedIn profile as my last one was actually 14 years old! But the one I liked was a bit cropped in the original photo and wouldn't have worked out the way I wanted. Here's my original photo:

Segmentation fault when running X program on Linux

I'm running Red Hat Enterprise Linux release 8.10. Yes, I installed Xming on my workstation. Yes, I configured Putty correctly. Yet I still had an issue. Problem When I tried to run an X program on my remote server with the display set correctly to my local

Zero Trust

Examples of implementing Zero Trust in your cloud architecture

Zero Trust, or Zero Trust Architecture (ZTA), was coined in 2010 by John Kindervag for the Forrester Research Group. The Zero Trust model shifts from "trust but verify" to "never trust, always verify". This post is intended to share a few concepts that can be easily

Oracle Database

Oracle User-Defined Functions

Last week, I presented to the Quest Oracle Community SIG on using Oracle User-Defined Functions and Oracle OCI Functions and how they could be instrumental in battling technology debt.

Cybersecurity

Setting up TruffleHog for repo security scans

There are a lot of code repository scanners out there, but I recently used TruffleHog to scan our GitHub repos due to its simplicity in setup and execution. TruffleHog is an open-source security tool that scans code repositories for hardcoded secrets, such as API keys, passwords, and private encryption keys.

SecDevOps

Principles of SecDevOps

DevOps is a methodology first introduced in 2007 and focuses on collaboration between development and operations teams to streamline software delivery. DevSecOps later came into the picture around the 2010 timeframe and extends this approach by integrating security practices into the DevOps workflow. DevOps addresses security concerns later in the

CloudFront

Removing AWS CloudFront access restriction from a country

We are developing a small web application on AWS, but we also restricted geographic access through WAF and CloudFront. However, we later wanted to give one of our offshore developers the ability to test the application, but he got an HTTP 403 error through CloudFront. The error on the browser

webMethods.io: Transformation Service, Ready to Go.

We completed the development of the Flow service last week. Today, we will test it and use the service in a webMethods.io Workflow.

webMethods.io: Transformation Service

In my last post, we discussed avoiding custom code for complex projects. It's time to get your hands dirty creating the first Flow Service for the integration project.

webMethods.io: Flow Services

In my previous posts, I have the custom transformation to normalize the ChatGPT completions. It's a low-level approach, thus a very effective one, with one significant issue - forward compatibility.

Creating a custom AI Chatbot in Java and OpenAI

This post describes how to build a basic AI chatbot in Java, leveraging the OpenAI API. Before beginning, make sure that you have Eclipse, Java, and Maven installed (see this post for instructions). Create an API Key on OpenAI An API key needs to be created on OpenAI. You must

Ansible: K.I.S.S. Optimization

It's fascinating, but our automation code is mature enough to have compatibility issues during the operating system upgrade. Let's see how violating the "Keep it simple stupid (K.I.S.S.)" principle leads you to trouble.

How To Watch in PowerShell

Every system administrator who runs a big system knows how to make long-running tasks less boring. Watching progress is one of those little fun things.

The Sin of Generalization

Our ancestors gifted us with a great ability: visual pattern recognition. It helped them survive by distinguishing tree branches from pythons and good fruit from bad. We train neural networks to recognize patterns, generalize, and create variations, with one difference: we teach them when to stop.

WebMethods.io: Custom Transformers

In previous integration posts, I briefly touched on the powerful mechanism of the Webmethods.io Transformers. Let's explore the data manipulation tools using a real-life example.

Ansible: Log Visibility Control

Ansible, originally developed as a state management tool, relies on logs to track play progress and target states due to its distributed execution. Let's discuss a few methods for controlling log content and visibility.

ChatGPT-4: Webnmethods.io Connector

Earlier in the series, we defined a custom connector for the new X API and established that a predefined connector does not work with the latest OpenAI models. Let's create a custom REST connector for the latest GPT models.
