Building Scalable Healthcare Data Workflows Lessons I Learned Using Power Query
****When I first started learning Power Query, I focused on the technical possibilities.
I found countless resources explaining how to build data connections, transform datasets, promote a row to headers, merge tables, filter records, and automate repetitive tasks. These tutorials were incredibly valuable. They helped me understand what Power Query could do and gave me the technical foundation to start using it.
But after working with Power Query in real-world situations, I began to realize th...

Two Skills I Built to Automate My Job Search with Claude Code
I'm a few months into a job search after a layoff, and I kept running into the same two problems: I was spending too long deciding whether a job listing was worth my time, and my resume was drifting out of sync with what was actually landing in interviews.
So I built two Claude Code skills , reusable, file-based instructions Claude Code follows every time I invoke a slash command, to close both gaps. This is a walkthrough of how they work, why they're structured the way they are, and what ...

I built RepoTrek: a terminal-first GitHub source browser in Rust
I built RepoTrek , a terminal-first GitHub source browser written in Rust.
GitHub:
https://github.com/yuna-r/repotrek
crates.io:
https://crates.io/crates/repotrek
The basic idea is simple:
I wanted a comfortable way to deeply explore GitHub repositories without constantly switching between the browser, terminal, and editor.
RepoTrek is not intended to replace Git clients such as git , lazygit , tig , or gitui .
Its focus is different:

Building a Production AI Agent in Spring Boot: The LLM Judge That Scores Your Agent (Part 8)
Last week I ran a demo of the agent for a colleague who was deciding whether to bet a feature on it. The approval gate from Part 7 worked exactly as designed. The agent searched, added to cart, asked for the address, and stopped at the confirmation link. My colleague nodded and asked one question: "OK, but is it actually good?"
I did not have an answer. I had 31 passing tests from Part 6, which prove the agent is bug-free. I had a state machine, which proves it cannot place an order without a...

How I Built a Counter Program in Rust and Learned to Trust My Tests
Building smart contracts on Solana using Rust and the Anchor framework requires a mindset shift from traditional Web2 backends. This week, I built a counter program, broke it on purpose, and used my test suite to verify that my security constraints were truly load-bearing.
Here is how the program works under the hood and why every test in the suite exists.
The Initialize Accounts Struct
In Anchor, security boundaries are enforced before your instruction logic ever runs. The Initi...

Unary gRPC on Reactor Netty: Event Loop Serialization, Trailers, and Cancellation
With protocol values and message framing complete, Stage 2 delivered the first end-to-end call: plaintext h2c unary RPC. This is already on main , and Stage 3 and Stage 4 subsequently completed all four RPC cardinalities on the same transport primitive.

How to Convert Files in the Browser Without Uploading Them
Most file-conversion workflows start with a trade-off that is easy to miss:
Choose a file from your device.
Upload it to a third-party server.
Wait for processing.
Download a new file.
Trust that the original and the result are handled exactly as promised.
That model is convenient, but it is not the only option. For a growing set of formats, a modern browser can read, transform, and export files directly on the user's device. The result is a different kind of tool: no upload qu...

Building an Open-Source NOAA MRMS Radar Renderer in Python
When I started building Weather Experience , I wasn't planning to release an open-source project.
I simply wanted to answer a question:
Could I build a modern radar rendering pipeline using NOAA's publicly available MRMS data?
That question led me down a rabbit hole of GRIB2 decoding, radar products, rendering pipelines, performance benchmarking, and ultimately the release of MRMS Renderer , the first open-source project from Taylor Creative Development.
Why MRMS?

Surviving the AI Bubble With Two Pieces of Junk From Amazon
Everyone is building agents. You should build escape hatches.
We are living through the most expensive group hallucination in tech history.
Every SaaS now has a chatbot stapled to it. Every CEO is an "AI thought leader" on LinkedIn. Every startup pitch deck is just the words "autonomous," "agentic," and "10x" in different fonts. NVIDIA could buy a small country. OpenAI burns through more cash in a quarter than NASA did getting to the moon.
And for what? So you can generate slightly wor...

Weekly Challenge: Uncommon parentheses
Weekly Challenge 385
Each week Mohammad S. Anwar sends out The Weekly Challenge , a chance for all of us to come up with solutions to two weekly tasks. My solutions are written in Python first, and then converted to Perl. Unless otherwise stated, Copilot (and other AI tools) have NOT been used to generate the solution. It's a great way for us all to practice some coding.
