[update]Add web service

Added REST API on Unity game, and created a Spring server to collect data and present it on a simple web page.

This version of web service is not on Azure yet. I was also testing JUnit and MSTest. Finally I complied to install IDE for Spring.... I have a very small hard disk, and already have Android Studio, Anaconda3 for Python, Visual Studio community, VS code, Unity, MySQL, OBS, Inkscape, Medi Bang Paint, Gimp, etc. Just unwilling to add another editor. I'm also supposed to install Decker....

Anyway, I installed Eclipse with STS support. And found it was difficult to test Unity functions related to position mappings, and nothing related to server needed testing. I tested time conversion and it would be much faster to create a main[]. The function I like in Duration is on Oracle Java 9..... not the public version, which Maven/Spring/Linux server uses, Java 8. Math makes things simple. I'm just lazy...

Guide to Preserving HuggingFace Models in Google Colab Environments

Conclusion: Step 1: find the model path: ls ~/.cache Step 2: Copy the entire folder to Google Drive: Step 3: Set model path to the subfolder under snapshot: My Story: I initially began exploring Generative AI (GAI) and Google Colab through Stable Diffusion. In the past, as I mainly wrote server services and console applications, I was less familiar with data science modes like R and Jupyter that can maintain a paused state. I didn't quite understand the heavy burden on Colab of creating a temporary Stable Diffusion WebUI with .ipynb, as suggested by popular guides. I just found it troublesome that connections often took a long time and then dropped, requiring a restart. Recently, while testing new versions of the Stable Diffusion model, and facing challenges due to Colab's policies making various versions of WebUI difficult to run successfully, I started researching how to write my own test programs in Colab. Eventually, I understood that Colab is ess...

docker: storage and services

Docker Volume Without going through Docker, accessing files within a Docker image is not easy. Therefore, Docker has a volume feature that allows users to specify the location on the host file system to serve as the access directory for Docker. In other words, a volume is the NFS of a Docker image. Example: Using a volume to store SQLite files. ref: SQLite for NodeJS: https://www.sqlitetutorial.net/sqlite-nodejs/ Initialize the project. # Setup ExpressJS framework express --view=pug 240324_ejs_sqlite_docker npm init npm install express npm install sqlite3 Test: npm start Initialize docker Since the directory already contains NodeJS, the Docker Daemon will assist in the setup. Create new docker image docker build -t atfuture7/sqlite01 . Create a folder for Docker, create a container, run it. mkdir docker_vol docker run -p 3000:3000 -v ./docker_vol:/data --name exp_sqlite atfuture7/sqlite01 After confirming that the container can run co...

Review old/new stuff: Angular 17

When I reviewed Angular recently, I discovered that it had just undergone a major revision three months ago, v17. The notes here are summaries of common features incorporated into v17. Install Angular ref: https://angular.io/guide/setup-local npm install -g @angular/cli Create new project ng new proj_name cd proj_name If the old project needs to be migrated to v17 control flow: ref: https://youtu.be/36Hcx7kRYDg?si=pmZcRkQHIlmguK3K ng generate @angular/core:control-flow Activate ng serve Data Flow ref: https://angular.io/tutorial/first-app/first-app-lesson-09 Service can be regarded as a custom class (similar to custom modules written in expressJS) ng generate service obj_name In the sample program, enumeration of array is used. this.housingLocationList.find(housingLocation => housingLocation.id === id); The concept is find( function(element) => { return (condition; )}) ref: https://developer.mozilla.org/en-US/docs/Web/JavaScript...
