dos's Introduction

dgisolfi

Synopsis

This is a repository for my various personal coding projects

Motivation

Most projects listed here are out of necessity or are created in order for me to learn a new language/skill.

Project List

ChatBot

My first attempt(of many) at a bot that interprets english and has some functions to assist someone.

A proof of concept script to run through all permutations of possible passwords for the login of Marist College. This is only intended to show my higher ups in the IT department the security risk and not for actual use.

MaristRegistrationScript

A script written by previous students of marist I have modified to work with current banner system. All credit for original script is given to Evan Hopkins, Antony Liang, Bob Nisco.

TwitterBot

Another bot that uses the twitter API to read and posts tweets. This also introduced me to Node.JS

chris-reminder-bot

Yet another bot, this particular one uses the twilio API to send SMS messages to my friend Chris who needs to be reminded to work hard in school.

groupme-chatbot

A bot that uses the Groupme API to converse with my friends within Groupme itself. This is bot is set up on a Heroku server and the first version available here is 69.

A standalone repository has been created for this project found here

kayvan-chatbot

A chatbot that is designed to learn from my friends conversation with it and build its ability to speak english using the chatterbot module.

erin-message-bot

A bot running on Heroku that uses the twilio API to send a encouraging text to Erin, then puts the function to sleep for x amount of time between 4-12 hours.

A standalone repository has been created for this project found here

phpDB

A mySQL server set up on AWS connected to PhpMyAdmin with a docker container for use in creating databases for my classes in Fall 2017 as well as for queries against the databases.

dos's Issues

Add a shell command called load to validate the user code in the HTML5

text area (id= “taProgramInput”). Only hex digits and spaces are valid.

Create a Verbose mode for easier debugging

Create a new shell command to enable detailed Browser Console logging.

UI for Disk does not output correctly

Fix your HTML, the table output is janky

Manually Writing to files cannot take spaces in the data

If space is placed anywhere within the parenthesis the file will not be written to Disk....small bug big problem

Loading programs after the 0 pid

A bug occurs where the running process object is not associated with the currently loaded process. This only occurs after the first PCB is terminated.

Branching with OPCode `D0` causes the execution to finish

When looking back and attempting to run the OPCode at the new position the data is read rather than the OPCode...must be that off by 1 error Alan was talking about.

Glados breaks everything

When loading the Glados2 script the commands are run before the Memory has been initialized. This is due to the speed of each. I may try to use quicker methods to mitigate this. Sadly the code may not be as clean as a result.

Display a BSOD message (on the CLI) when the kernel traps an OS error.

• Add a shell command to test this. Remember to include it in the help.

The OPCode `FF` gets stuck on hex val `4D`

The program gets stuck in an infinite loop...its pretty bad.

Dequeue Console error

When a user program has finished, and the PCB is removed from the running queue the console can no longer read the object. This causes errors in the Web Console, and undefined to appear for many values.

Enhance the host display with a graphic task bar

Enhance the host display with a graphic task bar that displays . . .
• the current date and time
• status messages as speciDied by the user with a new shell command:
status
example: status i love opera*ng systems

Any process other than the one in partition 00 does not complete

This is either a branching or Base/limit error. HUUUUGE Error...

Fix the "kill" command to check for numeric values as arguements.

Alan noticed in the previous project when kill is passed kill it attempts to kill the process "kill"...probably should restrict nonnumeric arguments

Implement scrolling in the client OS console/CLI

When running more than 3 process' the 3rd process, pid 2 is undefined

This Occurs only when using the function readMemoryBlock, however, all other processes' are retrieved just fine with the same call

Switching back to RR from FCFS does not work

After running in FCFS mode and switching back to RR, the CPU still runs like it's in FCFS mode.

Add new shell commands, date, whereami

• date - displays the current date and time
• whereami - displays the users current location (use your imagination)
• something else interesting and creative; surprise me

console/CLI enhancements

Other console/CLI enhancements:
• Accept and display punctuation characters and symbols.
• Handle backspace appropriately.
• Implement command completion with the tab key.
• Provide command history recall via the up and down arrow keys.

Add run all command

Create the ability to run all loaded programs in the partitions.

Loading Multiple Programs

Multiple programs can be loaded. However when the 1st finishes, somewhere it is being written to the next segment of memory. This causes issues with the next loaded programs.

Swapping Creates a out of bounds error at some point

During either roll in or roll out the process moving from disk to Memory is run and returns an out of bounds error.

Either in Roll in or Roll out the memory is placed odly after a few iterations of file swapping

the last bug possibly? (with my luck I doubt it.)
