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
https://spring.io/guides/gs/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
https://spring.io/guides/gs/accessing-mongodb-data-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
https://www.baeldung.com/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? 
 
  • Spring Data – Add custom method to Repository
https://mkyong.com/spring-data/spring-data-add-custom-method-to-repository/
Great examples.

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....

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...

Setup Maven and two basic projects

    The interesting implementation of Java I proceed to is Spring. And, only getting Java running is not enough. I also need to set up Maven. This name is new to me, and I found many Spring tutorials just skip this part. At least I need Maven to generate templates for me. I should learn it more. ( I knew there is a great tool -- Eclipse -- can make tedious things disappear. I’m taking a strategy to install all experiments I want to try and throw away when it's full. And that's an external VM, not my PC. I, not yet, want to do research about installing Eclipse on AMI. )    Upgrade to Java 8     First is to upgrade Java on AMI to Java8. AWS provides advanced tools for Linux 2. And DIY for Linux2. At least there are solutions for my choice.  Amazon Corretto 8 Installation Instructions for Amazon Linux 2 https://docs.aws.amazon.com/corretto/latest/corretto-8-ug/amazon-linux-install.html Here are commands I used: >wget */amazon-corretto-8-x64-linux-jdk.d...
