Task Talk
     Internal PRs:

      Firstly I needed to get people excited about Darkchatter, so I edited a text I made in a previous semester. I then added that to the Readme. Installing and Running the back-end can be a bit confusing to new comers so I made the first page of the Darkchatter wiki be a guide on how to install and run. I supplied the commands to install the necessary programs, along with a short video guide on running the program https://www.youtube.com/watch?v=AE0y7W8H928&feature=youtu.be



  Talking with other students, this seems interesting but its the challenge of getting started. I lent out my usb wifi dongle so that a student could use it with a VM (cant control wifi card exclusively on VM)

I took some time to view the other repo's and respond to the PRs. Answering any questions

https://github.com/DarkChatter/DarkChatter_Android/issues/7

Im starting to embrace Open Source leadership style I believe.

I was also excited to see that Muchtar had added command line args! Later he said hes going to merge it with my sample file , this will be great to work from.

Im hoping that we can have more PRs from others.

    For my other contributions Im doing alot of research on how to receive the packet the best. I supplied a sample function that would take the interface name and a string then broadcast packets with the string as SSID on that interface. With Scapy there are different ways to assemble packets and the most interesting case is building them off a string. It seems to just take the string converts it to bytes, assembles a malformed packet and still sends it. They can be seen back in string format by looking at the RAW(packet)  <---Scapy Function


Within the repo I included images of the byte maps in Wireshark.

 External PR

 For the External I wanted to pick something in-which I can use what I learned in my own application for PRJ666. I decided to look back at the RSA encryption app in-which I made a small change for Hacktoberfest. My task this time as I know its important for performance on Android, is to make the encryption and decryption threaded. I originally thought it would be really easy just start a thread and done, but since in this app I was encrypting then decrypting the same string I needed to make sure that the first thread would finish before the 2nd. I didn't really think about this and continued to think my variables weren't saving correctly, but after realizing in the output some decryption logs were called before encryption completed, i figured out what was wrong. 



Returning these threads made a workaround so I could control the handle for .Join()

 to make sure i have something to decrypt in the test

 My code changes for this are in my PR: https://github.com/sagarnayak/RSAEncryption/pull/2

 OnActivityResult (ExternalPR):

 Once I did the External PR I was on a mission! I needed to add threading to my application as during the encryption + Stenography the system hangs up for a seconds before resulting back to the activity. My goal going in was to use Threading to make this transition more smooth. After lots of fighting with the code, this was the result 

 In this case I needed to pass the thread multiple bits of information, I needed to implement a Runnable() that accepts the final variables declared above (They have to be final). When I did this I noticed a much more smooth transition when this workload was put on the system. I was really happy I was able to take what I learned in the external PR and apply it to what I have to do.

 The Improvement is at 20 Seconds in, Its still very rough
Also looking at the Network of project is really neat!

Introduction:  Repo  https://github.com/aagarwal1012/Image-Steganography-Library-Android Issue   https://github.com/aagarwal1012/Image-Steganography-Library-Android/issues/5 PR      https://github.com/aagarwal1012/Image-Steganography-Library-Android/pull/4     Today I found a good repo that I wanted to contribute to. Its relatively new so I think there's a good chance to get my work accepted into it quickly.  The Repo is an Image Stenography app in which encodes text into images encrypted with a password. Saving and encoding both are too much load on the UI thread and often cause the system to hang, I want to apply a fix of this nature to the save function for this app. When I first tried saving the photo I encoded the system would just hang and not function at all. The app didn't even save the photo. Work I recently had to deal with an issue regarding saving photos on android, and I noticed with this app that it never asked me permission to access my file to sa

Adding Simple Radios Ends in Bot Madness

Adding Simple Radios Ends in Bot Madness This very simple BMI calculator app has BMI calculation but no selection if you are a male or female which does change where you BMI 'roughly' a new stat could be added for those competitor types, 'percentile'  First thing I need to do is add radio buttons for selecting if man or woman! First lets go to the layout! With a constrained layout it was pretty easy to just set a radio group in. I had to ensure that it was anchored to the top  with the child item anchored to the bottom of parent. For the code, I need to add 2 blocks of code one for men other for woman that calculates what percentile the BMI is in. This will happen after the BMI is already calculated.  Just simple selecting the percentile and updating the text ! Now time to push and post a PR PR: https://github.com/characterdog/bmi-calculator/pull/14 When I did do a PR the bots blew up with stylenits alot of which w
