Docker: A Whale of A Time


Docker is another container service like Kubernetes. There are probably more prominent differences, but for now, I see that there is a whale.

Though we installed it through the GUI on Mac, we still use it through the good old command line / terminal.


We generated that with docker run hello-world, and while at first it gave me an error, it soon found the image from the hub, put the image into a container, and put it onto the bash. Technology is amazing.

Here's the tutorial! Let's look at 1.0 - 1.1




The actual files (notice that the key is different between this and the first image because I closed the program and opened it)


Actually opening and using Busybox on the Mac terminal with docker run busybox [echo "Hello"]


Listing containers with docker ps -a



The help list.


Removing containers (the first two after running docker ps -a starting with cefc and e678)

Making KPI Dashboards with PowerBI

 While this is the free tier, I cannot share or collaborate with others, nor can I publish content to other people's workspaces, but they will not stop me from screenshooting and recording these self-taught adventures,so! I'm doing this because I idly searched "Mattel careers" and "Information Technology", and seeing a bulletpoint saying the following: Analytical and reporting skills such as creating dashboards and establishing KPIs such as experience with PowerBI, Cognos, Tableau, and Google Data Lake/AWS is preferred And thought "Well, I've used Tableau, and I've heard about PowerBI,  even if its in-demandness is questionable , so how similar is it? And can I write about it?"  First, PowerBI (PIB) does have a downloadable, local version, but apparently Windows-only. I could download the .exe but I couldn't run it / drag it to applications on my MacBook.  Not a problem, we'll use the online SaaS version, and a dataset found here, ...

Recon and SSID - Mapping With VisiWave Site Survey

My laptop is refurbished. I've written about how there are a few ... quirks. Being a technology professional, I felt okay with adopting an older machine, knowing I had the skill to fix moderate issues. From dying drivers to monitor massacres, I've ID'd, solved, and documented a lot of issues.  The newest one was my Wi-Fi adapter dropping the connection to a specific extender. While troubleshooting, I was curious about doing recon of WiFi networks and broadcasting devices anyway. That issue? A power setting. It was so determined to save power, it would disconnect. The extender is also flirting with the older end of 6 years old.  The battery needs to be replaced, but that's new to me. As a Windows laptop, there are a plethora of options to pick. How do you decide which one is safest?  I am suddenly concerned about this despite having 3 unofficial, 15$ Macbook Air chargers from eBay, and no explosions. But let's move onto the Site Survey - Where can I find the stronges...

S3 Event Notifications Using Lambda

I earned my AWS Solutions Architect Certification in Feb 2026 (🎊) but Like Smash Mouth said, "So much to do...so much to see."  I've used Lambdas that, when an object was uploaded to a bucket, sent a notification to Eventbridge, and then sent me a text and email via SNS. Now, thanks to the free project on Adrian Cantrill's GitHub , I'm going to make a small image processing eventflow. (Emoji use is for fun; Everything here written by a human being.)  What's Happening: Images uploaded to an S3 bucket are made into 5 thumbnail variations thanks to the power of Lambdas and inserted into an output bucket.   Business Use case; If you want to get quick thumbnails.  Maybe this can be scaled out to do file conversion, like .txt to .pdf.  Materials: 2 S3 buckets - one for input, one for processed output. Lambda An image!  Step 1: Bucket Creation  🪣 I made one bucket (runtcpip-source, for images to go in) and copied the settings from it to make the second...
