Flask-- Getting familiar with Python

    Walk through example provided by Flask. https://flask.palletsprojects.com/en/1.1.x/

    After years of software development, "learn a new programming language" became abstract. If a 'language' is specialized, it probably could be taken as a tool/package. What I need to know is its APIs. What it can do, how the procedural goes and where to start are main purpose I should figure out. Learning a tool won't take too much time. 


    If the language is for general purpose, probably they all seem very similar........

    C++, Java, PHP, C#, Python, etc. are little difference to me. Of course each owns its specialty. Just because that they can do almost anything, How well a programmer masters these language might depend on how many packages/extensions the programmer knew. And this could be easily solved by internet. I assumed that, once seeing possible usage, an experienced programmer still not knowing how to use it is impossible. 

    Or, I'm talented? I'm flattered, if so. 

    This is the minor obstacle when I started learning Python. I may complete its syntax, logic and definition in one day, but I don't know what to do then. There are no problems I want to resolve by programming. I tried to learn python through Pandas or bioinformatic. Finally I thought website might be a good field while I learned deploying websites on Azure. Learning Flask is a side-product, ha ha ~

    Structure of Flask is beautiful. Its compact. For web pages, its tedious. Developers can't be too careful on dealing with potential problems a user may encounter in prior, and it costs many many pages. When learn NodeJS, the concept, one page web application, depicted the structure that one controller dispatches different content to users. There are no real pages for user to walk through. Flask is the first product I encountered that match this concept. Flask is compact. (Maybe the tutorial is a great advertisement Pallets made for Flask? Anyway, well done! )

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...
