I made a dashboard that tracks what apps and websites you visit the most and at what time. It was mainly coded in python. It recommends and shows apps and websites to you, allowing you to just open one thing and access everything else. It saves you time, keeps track of what services you use and for how long, and also can keep you organized. Due to the amount of data it collects, I decided to not put it on a website. Doing so would raise privacy concerns. To test it, you may download everything yourself on GitHub or watch my demo video. One of the most challenging parts in creating this project was actually things that you would think are quite simple–the website images and the UI of the website. The UI of the website definitely took super long (I’m not a very good artist and had to consult a few people). The website images (like what represents what website) took a surprisingly large amount time. I was confused on how I would get the website images. I tried apis and other complex solutions, but basically, you just take a screenshot and put it on. I’m defiantly proud of how fast I was able to put this together, I usually don’t finish my projects so fast. This was also some of the best UI I’ve done–even though that took a while.

I continued testing the peer to peer transactions today. It gave an unknown error 14 or something like that. It took a while to figure out what was wrong. I had to set up a fake environment with a mock up p2pool pool mining where each of my cpu core was a miner. When A tried to send B one Meepcoin, it errored because the fee was overcharging. It tried to charge 29 meepcoin before the fifth block. One of the biggest challenges in making meepcoin is not the actual coin code itself, but the code facilitating the testing of it.

I made the UI better. And boy does that look better than before. I added cool animations and better graphics. It went from simple html boxes and buttons to full on nearly-professional. I also spent some time figuring out how I would get the icon of a website (which is harder than it looks). I’m content with the new UI—that made a big difference.I definitely had fun in this project, and hopefully you did too, reading this!

Finished up and streamlined the tracking logic. I also made some files into .pyc files instead of .py’s to make it even faster. Also worked on the html of the local host page. I think this project is about done.

I worked on meepcoin daemon and wallet receiving logic today. Back to the explanations: the problem with normal cryptocurrencies, such as Bitcoin, Dogecoin, and Etheureum is that they all use the same hashing algorithm. The hashing is basically solving a puzzle/test question until you get it correct. If you do, you get rewarded with that crypto. Normally, cryptos use the same question (type) over and over again. Crypto miners literally hard wire their machines to just do that type of equation. Monero is different, it requires a different puzzle every single time. But Monero is meant for complex CPUs–something browsers can’t get. So instead of being like Monero and giving a 200 page textbook and having hard questions, Meepcoin uses a 32,000 page textbook with a super simple scavenger hunt. This is something cpus can do while being trapped in a browser/website.

I was able to finish the time tracker too. So before, it just looked and analyzed data in a straight forward way. Which apps do you use most? Which websites do you visit most? But now, it looks at the time, and then responds accordingly. For example, since I always check my email at around 7:00 AM, my dashboard would learn to recommend Gmail in the morning and then place it lower on the list later in the day. This was actually surprisingly hard though, because I used the wrong libraries in the beginning. I thought I would have to use like pandas and like the other data libraries from python, but it turned out that I didn’t need them and I spent 45 min just overcomplicating things. I turns out, time tracker != complex data analysis.

Finished debugging! No more errors. I was also like planning how I would work on this in the future, and my thought is that I could add a time tracker where it sees the time and refrences the time too, just like phones. I would probably change the listener (which runs 24/7) to also include timestamp and then I’d work it out with like the median, mode, and other stat stuff.

So I started this project a month or two ago. Meepcoin was originally supposed to be a quickie fork of Monero (a lesser known privacy coin with about 10 billion USD marketcap). I was experimenting with cryptography and crypto with all the time I had during the summer. Monero was nice enough to be open source, so I could check out all their code on github. I downloaded it and started messing around, and I was like ‘hey, it can’t possibly be that hard, right?’ (hint hint, i was horribly wrong).I named it after a random fun word: meep. Like it just sounds goofy and weird. But the thing about crypto is the mining—and if it requires complex 10k+ equipment, nobody will do it.That’s why I based it off of monero. Monero is like one of the only cpu minable (meaning like a normal computer can mine it) coins out there. So no expensive crypto mining or gpus needed. I  wanted to design a system that took this even further. Something that you can mine out of a browser: I wanted to make it so that you can mine out of Google. Usually this is impossible because browsers don’t get a lot of compute power. That’s why monero’s platform, Xmrig, triggers a bunch of malware warnings—because its saying”‘oh hi there macos/windows, I’ll skip you and directly tell the cpu to do a bunch of weird math equations–totally not what viruses also do.” That makes it unaccessible. Also like, software is hard and why not just go on a website?This log is way too long, I’ll explain the rest later.(Don’t mind the image, I’ll do more updates, but there won’t be much to show in my stage, its all just like boring code)At least you know my goal though. I’m like 60-70% (haha funny number) there already. Hopefully I can finish on Stardance.

So, atleast me personally, I use a bunch of apps. I’m gonna try to get a working prototype that like tracks how much time you spend on x app or x website and then give you the option to open them. I’m gonna try to lock in and finish all of this in one day (with future updates to make it better of coures (maybe like time tracking/ai stuff too!).
