#100daysofcode Day 60: I helped someone deploy their hackathon project to heroku (the hackathon is over, they just wanted to have it up). The idea is that you upload an image, and it removes the plants to simulate what might happen in the future: https://theyear2100.herokuapp.com/ https://devpost.com/software/2100

A few weeks ago, I went to the graduation for Year Up, which I volunteered for over the summer.

Year Up is a program for students who can't afford college to learn skills for 6 months, then get an internship at a tech company for 6 months.

If you know someone in the Washington DC area who would benefit from the program, pass this on! (boosts appreciated)

Here are some extra photos people sent #HoyaHacks #HoyaHacks2020

#100daysofcode Day 59: We finished up the app, adding a way to set a nickname for your devices. We made an authentication system similar to #nextcloud notification 2fa, where if a nickname is already claimed, you can request to also use that nickname. Then you have to approve the request on the device that is assigned that name, proving that you own that device/name. We won "best domain name" for http://www.scan-the.space/ and our prize was domain.com backpacks! :) https://devpost.com/software/scan-the-space

#screenshotsunday not much changes with my
laptop, so I figure I'll showcase something cool: You can play games in #LBRY! I thought it was just videos, but apparently you can publish JavaScript apps: https://lbry.tv/@OpenSourceGames:e/wubwubwub:e https://github.com/cwilso/wubwubwub I'm gonna have to try this...

#100daysofcode Day 58: We got #MongoDB Atlas set up, made a cron job to scan every minute, used #VueJS to make the page responsive -- it updates the table and graph when a new scan is done, and you can sort the table by any column. Also, the #raspberrypi is dual-weilding network adapters to scan 2 different networks for devices. https://gitlab.com/johanvandegriff/network-scenery

#100daysofcode Day 57: I'm at #hoyahacks, a hackathon at Georgetown University! My team is working on a tool to visualize devices on the local network: https://gitlab.com/johanvandegriff/network-scenery So far, we have python code to do an arp-scan, control a raspberry pi sense hat, and show a (mostly empty) dashboard with flask.

#100daysofcode Day 56: I set up a #storj node today, which is part of a decentralized, end-to-end encrypted storage network. You can sign up to be a node operator or a user (write an app with storj as the backend!) at https://storj.io/ I'm super excited about the possibilities of this stuff!

#100daysofcode Day 55 (yesterday): I migrated the website for my research team at school to github pages so anyone on the team can easily edit it: https://umd-aimar.com

#100daysofcode Day 53: We decided on file formats for the various stages of processed and labelled data, and my friend started working on a script to label the data for tensorflow. Also, new and improved RGB board for gamers! RGB = Red, Gray, Black!

#100daysofcode bonus! I put together the finished renders into one video using the #shotcut video editor (which parallelizes great out of the box). There are some issues with the graph videos being shorter than the others, so I slowed them down.

#100daysofcode Day 52: We put some final touches on the code, then started the render for overnight. The render actually finished in a few minutes, but that was without all the intermediate results, which make it take much longer. But tomorrow I'll have some awesome videos of the plots and stuff!

#100daysofcode Day 51: I cleaned up the code and merged the video processing code with the rest of the improvements. I also moved it to a git repo (I'm calling it BoggleCV :) https://gitlab.com/johanvandegriff/BoggleCV And here's a bonus GIF of one of the videos!

#100daysofcode Day 50: I used a row and column sum from #opencv and a peak finding algorithm from #scipy to split up the board into individual letters. Getting closer!

#screenshotsunday same old manjaro on my laptop, nothing fancy. I guess the only weird thing is that it has a pentium processor and yet it works for my daily driver. Also downloading wikipedia with #kiwix today

#100daysofcode Day 48: My friend applied the algorithm to videos, and I fixed some bugs and tweaked the algorithm.

#100daysofcode Day 47: We took some more pictures at a different resolution, then added a transform to correct for perspective and copy the board to its own square image.

#100daysofcode Day 46: My friend and I started using OpenCV to locate the boggle board in the image. We used HSV to threshold based on the color of the board, then found the contours, approximated the largest contour with 4 lines, and found the intersections of those lines.

#100daysofcode Day 45: With dask, I was able to speed up my algorithm by about 25-50% (on 4 cpu cores). Then, I thought of a new algorithm that is an order of magnitude faster (even on 1 cpu core)! It iterates through all the words rather than traversing the board recursively. (Also, missed a few days since I was a bit sick.)

#100daysofcode Day 44: I took some pictures of the boggle game to use for training for machine learning (more about that later!) I also taught my friend some python basics, and started learning dask.
