Gray Matter


Gray MatterGray matter refers to certain parts of the human anatomy. It’s present in the brain, brain stem and cerebellum, and throughout the spinal cord.

A walnut when cracked open, looks a lot like the top view of a human brain. It contains omega-3 fatty acids, which help support brain functions.

Below are the latest 10 posts featuring ideas that have leaked from my own gray matter at one time or another.

Creating a Website From Scratch on a DigitalOcean Droplet

RT Cunningham | November 20, 2020 (UTC) | Blogging, Computers, Web Development

You can choose to believe this or not: I've written this as an outline of the things I would need to do to create a website from scratch should I ever have to do it all over again. My memory isn't reliable enough.

Foreign Currency Exchange Rates in the Philippines

RT Cunningham | November 13, 2020 (UTC) | Finance

When it comes to foreign currency exchange rates in the Philippines, the main thing I'm concerned about is how many Philippine pesos I can get for a single dollar. The other thing I'm concerned about is which place will give me the best exchange rate.

PrimeOS is Android for Desktop and Laptop Computers

RT Cunningham | November 12, 2020 (UTC) | Computers

When I wrote about the BlueStacks emulator in 2018 (and rewrote in 2020), I wasn't aware of anything else that would run Android on a desktop or laptop computer. I recently came across PrimeOS while I was looking over VirtualBox images at

Can You Remember Every Place You’ve Ever Been in the World?

RT Cunningham | November 9, 2020 (UTC) | Travel

Can you remember every place you've ever been in the world? Not only the places where you've spent time doing something for more than a few hours? Can you remember the airports you've flown through, the expressways you've driven on or the states (in the United States) and countries you've passed through one way or another?

The Raspberry Pi 400 Is a New, Affordable Desktop Computer

RT Cunningham | November 7, 2020 (UTC) | Computers

The Raspberry Pi 400 reminds me of the original Commodore 64 computer from the early eighties. I know I'm not the only one in my age group to see the similarities. As of now, these computers are only available as pre-orders. They didn't even exist when I wrote about micro computers, even when I updated that post in 2020.

Raising Chickens in the Philippines

RT Cunningham | November 2, 2020 (UTC) | Food and Drink

I don't know much about city ordinances in the Philippines. They're obviously different in every city. I'm sure some places have restrictions on where chickens can be raised. Most Filipinos would simply ignore those restrictions or find a way around them. Having food on the table is far more important than following rules.

I've known about Slax for years. I just never bothered to examine it until recently. The website is fairly new (or at least the revised version of it is).

Using Debit and Credit Cards in the Philippines

RT Cunningham | October 31, 2020 (UTC) | Finance, Shopping

Unlike more modern consumer-oriented countries, using a debit or credit card in the Philippines is a hit or miss situation. Although there are shopping venues that take cards with the VISA and Mastercard logos, there are even more that don't. In those places, cash is the only thing accepted.

RT Cunningham | October 29, 2020 (UTC) | Computers, Web Development

Syncthing is a free, open-source peer-to-peer file synchronization application available for Windows, Mac, Linux, Android, Solaris, Darwin, and BSD. When I tried to use it a few years ago with my web server, I had issues with the software and I had to abandon it.

Self-Signed SSL (TLS) Certificates on a Local IP Address

RT Cunningham | October 28, 2020 (UTC) | Web Development

First things first. SSL (Secure Sockets Layer) is the predecessor to TLS (Transport Layer Security). Since people keep referring to TLS for websites as SSL, that's what I'll call it as well. Perhaps someday, no one will use the SSL terminology anymore.
