My First Blog Post!

Purpose

• To ride the wave of the AI revolution, learn to use various AI capabilities, and document my learning journey for review and sharing.
• I have absolutely no knowledge of HTML, CSS, JavaScript, TypeScript, Node.js, and I can’t really distinguish between front-end, back-end, full-stack, networking, and servers. But that’s okay, with the help of AI, I built a template in one day and deployed it online 😊. Then I gradually added new features, and in about three or four days, I completed the current system. Next is to start writing blog posts.

Architecture and Deployment

• Based on Deno, a JavaScript, TypeScript, and WebAssembly runtime built on the V8 engine and Rust.
• The framework is Fresh, a full-stack web framework based on Deno.
• Deployed on Deno Deploy, a globally distributed serverless JavaScript application platform.

Tools

• Cursor, an intelligent code editor from Anysphere.
• VSCode, an open-source code editor developed by Microsoft, on which Cursor is based.
• VSCode AI plugins cline, continue.

Article Format

• The blog post format is Markdown.
• The benefits of using Markdown are shown in the example below:

Displaying Mathematical Formulas

• Duhamel’s integral method for single-degree-of-freedom vibration
• Duhamel Integration Method
• Calculation method:
  • Cut the earthquake motion (external load) time history into small segments of impulse loads with different peak values.
  • Under the action of each segment of impulse load, the structure performs damped free vibration (a sine curve that gradually decreases).
  • Sum the responses (free vibration responses) under the action of each segment of impulse load to obtain the final displacement time history.
• Formula
  • At time $t=\tau$, the displacement generated by the impulse $I=F\cdot\Delta t$ is calculated according to the following formula:

$$\nu(t)=\frac{I}{m \omega_{n}} e^{-\xi \omega_{n}(t-\tau)} \sin \left(\omega_{n}(t-\tau)\right)$$

• • $\omega_{n}$ is the natural circular frequency of the structure with a single mass $m$,
  • $T_n$ is the natural period of the structure,
  • $k$ is the stiffness of the structure,
  • $\xi$ is the damping coefficient

$$\omega_{n}={\frac{2\pi}{T_{n}}} ={\sqrt{\frac{k}{m}}}$$

Environment Variable	Function
PYMAPDL_START_INSTANCE	Overrides the behavior of the ansys.mapdl.core.launcher.launch_mapdl() function, only attempting to connect to an existing instance of PyMAPDL. Generally used in conjunction with PYMAPDL_PORT.
PYMAPDL_PORT	The default port for PyMAPDL to connect to.
PYMAPDL_IP	The default IP for PyMAPDL to connect to.
ANSYSLMD_LICENSE_FILE	The license file or IP address in the format PORT@IP. Do not confuse this with the IP and PORT where the MAPDL instance is running, which are specified using PYMAPDL_IP and PYMAPDL_PORT. This helps provide licensing for Docker.
PYMAPDL_MAPDL_EXEC	The executable path to start the MAPDL instance.
PYMAPDL_MAPDL_VERSION	The default MAPDL version to start when multiple MAPDL versions are available.
PYMAPDL_MAX_MESSAGE_LENGTH	The maximum length of a gRPC message. Increase this value if your connection terminates when running PRNSOL or NLIST. In bytes, defaults to 256 MB.

Text Formatting

• **Bold** -> Bold
• _Italic_ -> Italic
• ~~Strikethrough~~ -> Strikethrough

Conclusion

This is my first blog post. I hope to keep it up and record my learning journey.
