How to Extract SSL Certificates from a PFX File on macOS
If you’ve ever been handed a .pfx file and told to “just upload the certificate,” you know the pain that’s coming.
PFX (PKCS#12) files bundle your private key, SSL certificate, and any intermediate certificates into one encrypted file. That’s great until you actually need to extract those pieces for something like an NGINX server, AWS load balancer, or third-party CDN that wants them all separately.
MacOS has OpenSSL built in, which is all you need. Here’s a simple shell script I use to generate the cert, private key, and chain in one shot and make them clipboard-ready for easy pasting.
Save the following as extract-ssl-from-pfx.sh:
Make it executable:
Then run it:
Follow the prompts. You’ll end up with three files and the contents ready to paste one by one wherever you need them.
Your private key is sensitive. Please don’t leave it lying around. Store it securely or delete it after use.
This script saves me time every time I deal with certificates. Hopefully, it does the same for you. If you have improvements or tweaks, I’d love to hear them.
Installing font awesome pro with bun
After recently switching to bun.sh, I was trying to install Font Awesome Pro. It uses a private registry but their docs have not been updated to support non-npm package managers and bun does not yet support .npmrc files.
You can configure a private registry using an organization scope. First, you must get your auth token from your paid Font Awesome account by going to your account page, scrolling down to the Tokens section, and copying the token.
Copy and paste this string, and replace YOUR_TOKEN_HERE with the token you copied above:
Open the terminal and enter these commands:
Paste in the config above with your token and then hit CTRL+X to quit, and Y to save when prompted. Now you should be able to run
How to Delete Folder with Special Character in Windows 10/11
I ran into an issue where a folder was created by some application with a special Unicode character that Windows Explorer doesn't seem to play nicely with. I also was unable to tell what the character was since nothing would reveal it. The folder's there, but you can't rename or delete it. If I tried to remove or delete it, I'd get an error saying the folder doesn't exist:
I have LockHunter installed but it wasn't able to delete it for some reason. The easiest way I found to delete the folder was to use Git Bash and then use the appropriate commands to rename or delete the folder.
Browse to the folder where the offending folder is located. For example purposes, I'll use c:\temp\folder1
Rename:
Delete:
If you don't have Git Bash or are not a developer/power user, you can download the portable version from https://git-scm.com/download/win to use temporarily. Once you decompress the files to a folder, you'll find git-bash.exe which you can double-click to run and use the above commands.
How to Setup CI/CD of Jigsaw Site to Digital Ocean Droplet Using Bitbucket Pipelines
I created a new personal resume site and decided I wanted to build a static site since it wouldn't be frequently updated. I evaluated Nuxt, Gatsby, and a few others but settled on Jigsaw, a static site generator based on Laravel. I had never used it before and figured this would be a good learning experience while building something I needed. I was pleasantly surprised by how easy it is to use and setup, so kudos to the Tighten team for putting together such an elegant solution.
I wanted to get a CI/CD pipeline configured to handle the site's deployment but couldn't find any working tutorials, so I'm sharing my solution in case it helps others. I'm using Bitbucket for this since it's a personal private repo, so I'm using Bitbucket Pipelines.
After you enable pipelines for your project, you'll need to configure a Pipelines Repository Variable in your project. Go to the settings tab in your repo, and then select Repository variables:
Add 3 variables:
Generate an SSH key (or use your own) and add it to your server under the SSH Keys tab in Pipelines:
I generated a new key and then added it to ~/.ssh/authorized_keys for the account.
Add this YAML snippet to your bitbucket-pipelines.yml in your root. This will use PHP 7.4, install rsync, node + npm, composer, and build the production version of the site to deploy to the specified folder.
The -aVP switch for rsync is to give me verbose progress feedback so I can see what's happening. If you don't need the detail, switch it to -a.
I received a few errors when rsync ran. In case you run into them as well, here's the list and fixes. The first was:
rsync: failed to set times on "$FOLDER": Operation not permitted (1)
I added --no-t to resolve that and then got a new error:
rsync: failed to set permissions on "$FOLDER": Operation not permitted (1)
which was fixed with adding the switch --no-perms. My final rsync command became:
How to Clear Archive & Read-only flags on Files in Windows in Bulk
I ran into an issue where I had to move files from one system to another and was running into issues because files had been set as read-only, had the archive flag set, or both. It was causing the system to skip files which wasn't acceptable. Normally you could just use Windows to clear it in bulk, but that could potentially mess up file permissions. I needed a way to automatically just clear all flags but respect permissions.
I did some searching and didn't find a utility that would do the job and most of the solutions I found required Powershell which wasn't available on the system I was on. I ended up writing a quick console application in C# to do the trick. I've made it free and open sourced it in case anyone wants to use it.
If you need just the app, you can find the release build here with instructions. The app also prompts for input to make things a bit easier to use. There's no install, no tracking or metrics, or anything else related to privacy concerns in this app. It's a simple throwaway utility to get the job done and move on.

If you want to see the source code, that is available here:

Please note that I did this in about 10 minutes for my own use so error handling is pretty much non-existent. I mention this because I did run into one issue where Windows was somehow seeing a folder with files in it as a file and it couldn't be deleted or renamed and the utility couldn't get past it until it was resolved. I didn't spend much time debugging and just used my Mac to rename the folder and Windows was able to recognize it after the change, so the utility was able to continue processing.
How to Generate a Page for Each Day of Month in Microsoft Word using VBA
I briefly joined my wife at her practice to help her grow the business and figure out how to make things more efficient. One of the things I learned is that my wife created a sign-in sheet for the office in Microsoft Word. Every week she would open the file and manually enter the date for each day of the week and then print out the documents. I took over the responsibility for a month and it annoyed me due to how inefficient the process was and I decided to automate the entire thing. I couldn't find a solution to the problem online so I had to roll my own and am sharing the code in case someone else can benefit from it.
The script will calculate the first day and last day of the month and then do a loop to append the date in the "Day, Month day, Year" format (i.e. Thursday July 17, 2019) to a text field.
There are a few important steps involved to get the script working as is:
Open up Word, then open up VBA, and copy and paste this snippet into a module. When you run the function, it'll create a copy for every day of the month. I also created a function to start at a specific date in case you run it in the middle of the month.
How to Get Laravel Debugging to work with PHPStorm and MAMP Pro 5
This has been one of the more aggravating things I've had to deal with in setting up software for development. I've followed the official documentation from JetBrains, over 30 other blog tutorials, and literally failed in getting any of them to work.
I figured out an easy way to make the setup work so I'm sharing it in case someone else finds it useful and for self-reference since I'll probably forget how to do this again in 6 months when I start a new project.
Happy debugging!
Self-signed SSL certificates not working with MAMP and Chrome
I use MAMP Pro for most of my PHP development and Chrome has annoyingly been blocking the self-signed SSL certificates MAMP generates, saying the certificate is not valid and "Your connection is not private":
Thankfully, I found an easy solve to fix this. These steps assume you've created a host in MAMP. You'll need to go to the SSL tab of the host you are trying to fix and
Go back to Chrome, and reload the page and the certificate should work now:
How to get shape type in Visio using VBA?
I'm working with a Visio 2016 file with over 100 tabs and need to extract the data (mainly text, connector from/to, and shape) for data processing for a processing engine. I was trying to figure out how to get the shape type name in Visio using VBA. For example, in a flowchart, I'm trying to figure out how to tell if a shape is a process, decision, data, etc. The
property seems to always return 3 which appears to be visTypeShape from https://docs.microsoft.com/en-us/office/vba/api/visio.visshapetypes. After hunting through all the available properties on the Shape object, I found that the shape.Master.Name property will return the shape name, but you need to check if it's Nothing first in case it's not a shape.
I didn't do that and it kept breaking the script originally because some of the pages had text fields and the first few items on the first sheet I was working with were text boxes. Hopefully this snippet will save you the time I wasted figuring it out.
