While digging into some potential memory issues in a Lucee container, I found myself needing to analyze a JVM heap dump. A little research indicated that Eclipse Memory Analyzer (MAT) was the way to go. But I had to jump through a few hoops to get it working on my M2 Mac.
I recently learned about the function arraySet. It's a niche function, to be sure, but I nevertheless found that it served a useful purpose when creating arrays.
On more than one occasion I've wanted to quickly check the size of a database. Fortunately, PostgreSQL has a function for that, so we can run a query to find the answer.
While there may be times you need a full-featured Slack integration, just being able to send messages to a channel can be a win for many applications. I recently needed to alert a Slack channel whenever an application was deployed, and found that using Eric Peterson's module Hyper along with Slack's Incoming Webhooks did the trick nicely.
In ColdFusion applications, I tend to use the AntiSamy Java library to sanitize user-supplied input. While updating to the latest version of AntiSamy (actually, the snapshot of an upcoming release - more on that later) I documented the process, and particularly how Maven can make it easier.
I'll begin by saying that a substantial portion of this post is deeply indebted to Tony Junkes, who has blogged quite a bit about using ColdBox modules with FW/1. The approach I ended up taking is slightly different than his, so I thought it worth documenting.
As a quick follow-up to my last post about storing database credentials in AWS Secrets Manager, I wanted to walk through retrieving them using CFML, so you can actually use them in your application.
Today I learned that AWS Secrets Manager enables you to store the login credentials and connection information for a database in a single secret. I'm not sure how I missed this earler!
This should be a short post, on a pair of complimentary functions that I just learned: objectSave and objectLoad. I'm not sure I've fully grasped their practical utility yet, but they're certainly worth knowing.
Just a small note here, for my own reference, and also to get myself back into the habit of blogging. I found VS Code's highlighting of matching brackets a bit distracting, so here's how I modified it to be a little less "in your face."
