VC# and chart/image viewer

Walk through code related to charts, browser and image viewer.

It's a good thing to know how others deal various object in different way, though everything is simple on textbook. But, still, some doubts raised since the outcome is not ideal. For example, how could I create a modern browser if the version VC visual design provided is not supported by most website.....? I have to break into main loop and find out where objects are initialized, instead of waiting for system dispatched event, right? or find some way to breach the main flow...? Probably this is viable solution, but a little ugly.....

Most functionality could be done by VC UI, even the author mildly expressed that coding is almost neglectable.... As what I mentioned on last post, this is a book for VC, not for C#..... I will still complete it. At least there are examples showing me how functionality are performed. And hopefully this could be break into raw functions without assistance of visual design.

For nutrition balance(?) I squeeze some time to read a book about python and machine learning. But the book for machine learning was just too theoretical. At first 3 chapters, all are about definition and explanation of "learning". It may triggered by attempt to survive, learn from chance, learn from logic, from mimic, etc. Nothing to do with python.... too bad ....

Dissected out codes that I think might meaningful. Comment later. Too sleepy for now.

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....

gamer's interview

This project simulates a gamer's interview. Based on NodeJS+ ReactJS The setting is interviewing a gamer/journalist what's his/her plan of March 2020? The gamer answers his/her game list in plan, how many reviews on demand and how many hours expected. Games selected for review take 5 hours for each, while others take one. This project is designed to practice render html, jsx, component, props introduced in https://www.w3schools.com/REACT/default.asp . Also fixed other issues to make it work. When trying to modualize objects and tools, my design developed to separate views and processes. And it is quite similar to the initialized structure NodeJS+ReactJS provided. Furthermore, since include local module files are banned by browsers, use NodeJS service seems to be the best option. view file main process object tool

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...
