time-table | DevOps goals it to build process | Continous Integration library

I am trying to create a if statement where the user must select a time between 7am and 16pm. I have searched on Stack, WESchools, MDN and written the if statement in a multiple of ways and still can not get it to work correctly.

Either the alert pops up, no matter the time inputted and the code wont run, or the code will run no matter the time put in by the user.

Here is the code:

I am building a charge schedule off of the user input for my reflection and I am stuck on whether to try find and adapt a plug in, or build it myself.

The schedule is a solar charge schedule to charge electric cars between the hours of 7am and 16pm. There are 6 cars and 6 solar chargers.

I have built the first table where the user inputs the car registration, the amount of miles left, the amount of miles needed for the next journey and the time they need to leave for that journey.

The schedule must take in to account the above and then generate a charge time table so each car is sufficiently charged for the next journey.

Each car has a maximum range of 250 miles and the cars charge at 44 miles per hour.

Here is the JSFiddle with the whole project: https://jsfiddle.net/Coxy/1r30xgjc/3/

I am trying to change the background of table cells based on the user input.

If the user inputs 3 hours, and the time at 10. Then I need to change the background of table cells 7-8, 8-9, 9-10 to display this range.

Here is the HTML:

I am still pretty new to JavaScript and trying to improve my very basic skills. I've built a simple table where you enter the car reg and the car name pops up, you enter the miles left, and the miles needed and it calculates how many hours until you need to charge.

Currently you have to enter car 1 reg number in to the first row, car 2 in to the 2nd car 3 in to third etc and was wondering if there is a way to rewrite the if statements so that you can type any car reg in any order and it still pulls up the correct car name.

I tried putting the car reg's in to an array and calling the array to check (the var is still there) but I couldn't get it to work.

Here are the if statements :

Please consider these three models:

I am trying to built a attendance app for my college where in I am fetching data for a web time-table application which has a sql backend and there the lecture start time and end time is in format 1518427800. I am not even sure what format is this.

I am using node.js to fetch from mysql and push it in firebase database, but before i pushing it in firebase. i want to convert the datetime format into something that is understandable.

I am not allowed to alter anything in the web application or its database.

I was looking at the docs for PostgreSQL, and in the datetime section, the precision for time and datetime is given as 1 microsecond. I want to use this precision in the ISO 8601 precision. In the docs, I also found an example, see Table 8.11. Time Input in the doc:

https://www.postgresql.org/docs/current/datatype-datetime.html#DATATYPE-DATETIME-TIME-TABLE

The example given is 04:05:06.789. Now my question is, is .789 microseconds? Since it is only 3 digits, it looks like it is in milliseconds. And if so, how can you represent it in microseconds in the format HH:MM:SS.FFFFFF, where FFFFFF are the microseconds?

I'm working on the project where university course is represented as a to-do list, where:

• course owner (teacher of the course) can add tasks (containing the URL to the resource needs to be learned and two datetime fields - when to start and when to complete the task)

• course subscriber (student) can mark tasks as complete or not complete and their marks are saved individually for each account.

If student marks task as complete - his account + element he marked are shown in the course activity tab for teacher where he can:

• initiate a conversation in JavaScript-based chat with him
• evaluate the result of the conversation

What optimization algorithm you could recommend me to use for timetable rescheduling (changing datetime fields for to-do element if student procrastinates) here?

Actually, we can use the student activity on the resource + fact that he marked the task as complete + if he clicked or not on the URL placed on the to-do element leading to the external learning material (for example Google Book).

For example, are genetic algorithms suitable for this model and what pitfalls do they have: https://medium.com/@vijinimallawaarachchi/time-table-scheduling-2207ca593b4d ?

So I am trying to do this project for a class, where I simulate a distributed network of computers using sockets. And then each computer will write an event object that contains its ID and timestamp, and each computer will also read incoming event objects and compare the timestamp between its own and the one sent.

I thought I got everything working properly, until I look into my logs, and something seemed strange. I notice that the computer is reading the same object over and over, even though it should of received new events generated by other computers.

Here's the code for generating and writing events to the socket
