I would greatly appreciate any feedback you might offer regarding the issue I am having with my Word Prediction Shiny APP Code for the JHU Capstone Project.
My UI code runs correctly and displays the APP. (see image and code below)
Challenge/Issue: My problem is that after entering text into the "Text input" box of the APP, my server.R code does not return the predicted results.
Prediction Function:
When I run this line of code in the RConsole -- predict(corpus_train,"case of") -- the following results are returned: 1 "the" "a" "beer"
When I use this same line of code in my server.r Code, I do not get prediction results.
Any insight suggestions and help would be greatly appreciated.

I am newbie to Vim world, and I see so many people using VIM, whats the convincing part of it that attracts people? i mean they can already use the GUI based Editors , aren't we moving backwards? . I've read so many blogs, watched videos, still didn't find the perfect sense to use it.
If anyone is experienced can you tell me in simple English what is the purpose of VIM over Other Development environments.
How will it help me in my C++ learning journey? or will it?
I dont think it is good question to ask here, but i am very curious to get some insights.

I am getting the below error when trying to use the JSON_TABLE()
function in MySQL 5.7–compatible Amazon Aurora.
Error Code: 1064. You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(@json_col, '$.people[*]' COLUMNS ( name VARCHAR(40) PATH '$.na' at line 1
In Amzon Mysql JSON Documentation states that it supports a lot of JSON function. However JSON_TABLE
is not listed among them.
I can execute the below query in Mysql 8(Which is not AWS Aurora) and it gives me the below result.

I am working on the little exercise and writing tests for it. All my tests using GET
with endpoint ('/api/blogs') are working but when it comes to POST
data it gives a weird object:
ANSWER
Answered 2021-Jun-13 at 10:29I don't think you need to use new Blog
in your test, it will create an instance of Mongoose document (the weird object in your log). Create a Mongoose document is the job of the API. You only need to send the Javascript object.
QUESTION
I am trying to develop an app with a modular approach using requirejs and include only as little jQuery code as possible as necessary. I have a basic SPA app o.html:
...ANSWER
Answered 2021-Jun-12 at 23:09While I can certainly change the context of $(this)
by using $.call(Object, argument)
or doing an Object.assign({}, object)
somewhere in the code, to manipulate the $.fn.init(selector, context)
of jQuery, I have decided to create an alternative Vanilla solution Framework.
And, while jQuery is worth pursuing, I have built this custom CORE jQuery support library in stead. In other words, this framework mimics everything in the jQuery syntax as shown in the minimum code example. I believe that this is also the missing manual that most developers need that is virtually impossible to search these days in the internet due to jQuery's popularity & search ranking wars.
The goal as mentioned in the OP is to try to include only as little jQuery code as possible or implement an alternative solution with the jQuery snippet as needed because jQuery has grown so huge with newer versions and extensions and most of those code have considerable performance overhead other than the learning curve.
With this new CORE, I can easily extend support for jQuery, with $.fn.extend
or $.extend
or $.prototype.extend
and for future use cases whenever the need arises, do another plugin for some basic routines or re-plug $(function()})
or $(document.ready()})
or implement other custom filters and jQuery-like chores, some of which I have already built and stripped off from this code such as event handlers and the $.ajax
.
The good news is, we can even reuse already built favorite jQuery plugins without having to worry about compatibility issues because the power of jQuery is already in our hands! The core also preserved our favorite dot notation among others! :D
Overall, this is very handy whenever building minimal, manageable, reusable, modular Javascript, as well as building on top of the missing Vanilla learning curve and understanding how browsers work, especially because the heart of jQuery which is the $.extend
is herein preserved. Some of the mechanics of this library though (about 2% of the code), is ported from jQuery and I'm planning to build on top of this CORE for my projects without having to worry about licenses.
That said, I hope this will be helpful to some developers out there. I'm licensing this code with MIT.
