Thoughts, interests, brain storms, learning... All the blog article posts will start from the topic shown in this section.
A long time ago, when I touched keywords like map/filter/reduce in Swift.
At that time, I generally called it Syntax Sugar. Today, I got a chance to continue digging into this concept as I am touching LINQ in C#.
My learning started from this fun pic:
After some investigation, I got this mapping from Swift to C#:
More secure way to deploy GitHub Page with repo in resource-public.
With the security concerns of exposing source Markdown files and Git history, I recently switched my previous public GitHub Pages repository to a private source repository, which will only be responsible for building and deploying to a separate public repository.
Let's check the best practices for this private-to-public deployment setup!
Let's take my old mkdown blog repo ytianle.github.io as an example, which was public and contained both the MkDocs source files and the generated static site. This meant that anyone could view the Markdown sources, commit history, and author information directly on GitHub.
ytianle.github.io (public, contains both source and generated files)ytianle.github.io → ytianle.github.io_private (MkDocs source, scripts, images, raw notes, build tooling)ytianle.github.io (public, contains generated static files only)A powerful tool to identify which extension is causing issues in your VS Code setup.
Found an interesting VS Code feature: Extension Bisect. It helps you find out which extension is causing problems in your VS Code environment using binary search. This is especially useful when you have many extensions installed and are experiencing performance issues, crashes, or other unexpected behavior.
Figure: VS Code's Extension Bisect disables half of the installed extensions at a time to narrow down which one is causing the issue.
FastAPI + Web + pywebviewA creative architecture for building desktop applications with shorter delivery time for a certain class of desktop tools.
Recently got a new way to build desktop applications. This is not a typical Qt desktop application. The core idea is:
FastAPI backend servicepywebview to make it a desktop app.The interesting part is that this is still a real installable desktop application, not “just a website in a browser”. In practice, the release pipeline can use:
GitHub Actions builds the app.PyInstaller produces the executable.Inno Setup creates the corresponding installer.Radiosity and Ray Tracing?I found the below PDF material (Resource from MIT) provides a good answer to this question:
Ray tracer and Path tracerHere are the useful resources about ray tracing I found today:
Try-catch"
Try-catchshould never replace proper control flow. Don’t use it to handle null references or check for empty lists. It’s not meant for regular logic — it’s meant for unpredictable failures like file I/O, networking, reflection, or untrusted input."
