Spring simple and MongoDB (Finally)

Finally~~~ I could start a Spring project ~~~~ 3 days ago.

Following the user's guide is simple. ...... and then difficult. Not to go astray is a difficult task for my curiosity.... My second day fell in the trap of using an external DB and then found my development server was not whitelisted. The third day fell into mysterious naming convention..... Why is it not noted on User's Guide?

In case Spring 2.3.0 covers up everything (just kidding) or I forget everything while moving on, I keep a note here.

Building an Application with Spring Boot

This “quick start” was not well designed, but provides a more comprehend snapshot of Spring Boot full stack development. Only when I encountered various issues then I found this is a saviour.

Accessing MongoDB Data with REST

No property found for type… custom Spring Data repository

https://stackoverflow.com/questions/41467894/no-property-found-for-type-custom-spring-data-repository

The post saved my life(?!). Naming convention. Maybe I found this post very early, but just didn’t believe it. Until I can’t find anything help resolving linking error (or spring mvc fail to create), why not trying “change names”

Spring Data Composable Repositories

This site seems new but introduces many practical concepts, although its same code is fragment. I guess it is because it also provides paying courses?

Bookmark service (MongoDB & Spring REST) -2/2

I accidentally deleted my development VM. I got lucky having the habit of taking notes. This blog is useful. Development VM is doom to be lost. Rebuild it waste time, but having a clean slate is refreshing~. What concerns me more is my AWS free quota this month is reaching 85%. The second VM I launched but never being used might be the one to blame. (Of course, my mistake.) I terminated the wrong VM. Now I got Linux 2 built. Great, just threw away everything happened on AMI. 1st layer: Page Page class Originally, I need to prepare getter/setter for all class properties for Spring. By using lombok, I only need to create constructors. lombok will deal with getter/setter and toString(). But there are chances to call getter/setter, but how? .......Naming convention.... Capitalize the 1st character with the prefix get/set. Annotation @Data was used on this class. Repository class Spring Docs: Repository https://docs.spring.io/spring-data/mongodb/docs/3....

Comments for my Server/Client Web API samples

Finally, I finished the comments for python/07 and 09 projects. I almost forgot to put the date on source code which is used to note how long it took me. Not precisely in hours….. I didn’t include source code in my previous post. If choosing code-section for this post…… maybe I want to mark out my comment….. (Really?!) Once my work was developing websites for enterprises, including ERP, CRM or content sites. The sustainability of network and security are important issues. There are 2 methods for HTML Form submission: GET and POST. Submit via POST is secure, compared to GET which piles parameters on URL. RESTful API is mainly using GET. Yup, even if you have a certification key, if you put the value on the URL, it is visible data. When writing socket-communication, client-server sockets are a pair; both follow the agreement on commands and structures; and there are countless ports for usa...

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...
