Technical training

When the enterprise buy existing products, some of the developing company provides technical training that helps the enterprise customize their own product. In business's perspective, this model indicates that the developing company sells semi-manufactured goods, and transfers customization expense to the buyer. (In retouched terms, the developing company builds reliable tools and allows the buyers to modify by themselves.)

At very beginning, there are lots of work to do to apply new IT products on the enterprise; and then the modification demands decreases or finally goes ceased.Stability might be the reason of stopping; or the aging of the tool. Should the enterprise take those trained specialists as long term workforce?
Probably not. They are the expense saved by the developing company and transferred to the enterprises.

Like buying firmware, applying software should take deprecation into consider. And trained specialists should be included.

Will the data in this tool disappear when the specialists leave?
Senior developer is here for this purpose. Senior developers need not to be so skillful as those specialists that use the tool for development, but senior developers should be able to extract data from the tool, analyze data and import it to another new IT products.

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...

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...
