Arbitrage tool for Hypixel Skyblock

 While reading a book, read about keeping a knowledge portfolio. I liked this idea, but it was talking figuratively like learning new things and absorbing new information. It was a good idea and I was worried about forgetting things, so I wanted a way to look back and relearn things. I created an extension that made an icon on the bottom of a code snippet. When you checked the icon it would add the item to a database where you can view on a website. It was a very fun project and taught me about the permissions that extensions have to the website. I also improved my problem solving and how to pass params back and forth depending on permissions and when the project is initialized. I had a lot of fun with this project and I think that I will find it useful in the future. I started by injecting HTML code into the bottom of each element. I then continued by using the data of that html element along with data from the chrome API to create a POST request. The post request was to my own website and allowed me to upload the data to my database. Which I then used to interpret it into a page on my portfolio.

After learning how to use react I wanted to build something. I wanted to build something that I could use. I realized that I needed a portfolio to showcase the rest of my projects. I started by building the user authentication. Then moving onto the posts, then the contact page. The hardest part was relearning a technology that I had not used in a while. That being three.js. I used React-Three-Fiber which was more different than three.js then I would have thought. Using react three fiber I created a revolving model of all of the technologies I had used along my coding journey, Including: Python, Javascript, HTML, C#, Unity, and even building my own CNC mill. I spent time working on details that I thought did not look as good as they should which included adding a 3D text effect to the main headers, and adding a timeline to fill up extra empty space. I learned many errors and fundamentals about why some of the things that I was trying to do did not work with the frameworks I was using. I then pushed through and used different solutions such as the way that I did some styling on the page. I wanted to change the way that some pages looked when the page was vertical, but not all of this could be done in css. I ended up writing a function that figured out if it was vertical only to learn that react and next could not get the window width normally, so that took a workaround. One of the strangest errors I had was with the 3d text. When I resized the window the point at which the text changed to black was at the same height no matter the width, which caused the text to never fade out into black if the width was too small. In the end I used linear algebra to create a formula of values based on the height that made the text look normal. The final formula was blackPoint =  (0000003030303030303 * width) + 0.001195757575758. This was used to calculate when the text should turn black. This project was my very fun and useful.

Continuing to try to learn to react to one big tutorial I followed was one on how to make a blog. A tutorial on how to make a blog is the perfect project because it teaches you about backend data structure and how to manage the posts and data that your site is supporting. It is also a perfect project because it teaches you about user authentication. Lastly it teaches you the right practices and security measures that should be taken place in order to make a fully functional blog. I use these skills that this tutorial taught me and continue to use the same practices and skills in my future projects. Some of the key features of this blog was the ability to authenticate users through Google. This was done using the firebase authentication API. It also uses firebase's firestore database. This is a document based database that makes it very easy to store data such as blog posts. This site is not used currently, but it is still deployed on vercel. One of the other main features of this blog is that it has the ability to have a paginated homepage with database cursors and constantly generating results. It is also made with ISR (incremental static regeneration) and SSR (Server Side Rendering) it is also made to be as SEO (Search engine optimized) as possible. I think that this was one of my biggest learning projects that i have ever done

Advanced Blog

 I wanted to start learning React and how to start making more professional websites.I chose React for its popularity and compatibility with many packages. I was also used to node.js at this point so I understood the way that a backend and frontend functioned together. After deciding that I wanted to use react I started looking for tutorials. I then decided on fireship.io. There were many tutorials and all for a normal price. I started the tutorial there and fixed some bugs I experienced. The coolest part of the project was that it was a PWA. This means that it was able to run offline along with a bunch of other features. I was fascinated by the idea of a website being able to run offline. I have tried to incorporate this into my projects ever since (Only when it made sense). Once I finished with the course I continued to edit the project, And I made it better. I changed up the styles and also fixed some bugs that were in the original code. It was a very fun project and it taught me the fundamentals of react and PWAs and i have used those same fundamentals ever since

I was browsing across youtube when I came across a video by firebase. It was about how to make cool 3d backgrounds. I found that interesting and followed along with the code. In the tutorial it taught me the basics of how to set up a three js scene and what it took to make it. I learned the basics and that combined with the experience I have had with blender I was able to figure out how it works. I learned about how to create scenes and work with lighting and cameras. This project did not end up going anywhere and did not get used much, but I was able to take this skill and use it later in my portfolio. I used react three fiber in my blog which was different from normal three.js. This project also let me figure out later the differences between these two different versions of the same module. It was a fun project in which I learned about how 3d rendering works in javascript.

3d Background

At the start of quarantine I started sitting at my computer a lot more (and coding a lot more), so I wanted a standing desk, but I didn't just want any standing desk. I wanted to build my own. I discovered linear actuators, so to my younger mind it seemed as easy as strapping two actuators to the side of a desk and adding power, but it was not that easy. For example, at first, I needed to build a table that could move up and down. Because I did not think that the actuators were not stable enough to support the table by themselves I needed strong thick moveable legs (which ended up being 100% necessary). I used the original legs for a table I had and strapped some cabinet sliders (to combine the two pieces while still making it able to move) to the side of the legs. I then made a wooden box that would fit outside of the legs. Finally, I screwed the cabinet sliders into the outside box. This made it so that the table could be lifted with my hands, but had no way to move automatically. I solved this with some linear actuators. I also bought a three-way switch, 12v AC to DC converter, and a speed controller because one of the motors was a lot faster than the other. The fact that one was faster than the other ended up being a super big problem because the speed controller could not have the input polarity reversed. The way I had the Wiring done the polarity was reversed before the speed controller. Which the speed controller would not allow. I also can't put the three-way switch after the speed controller because there are only two input terminals on the switch. The price for this was already getting high, so I did not want to buy a new speed controller. This caused me to take a break from the project for about two years, in that time I got a standing desk off of amazon. Later in 2022, I wanted to revisit the project not because I needed the desk, but because I needed the wiring experience. After buying some relays from the micro center and grabbing an Arduino I already had, I was ready to go. I wired it up so that the Arduino could control the two motors and their polarity. I then 3d printed a case for the whole thing and put it on the bottom of the desk. IT WORKED.

Standing Desk

Because i played alot of video games it seemed inevitable that i would want to code my own, so after a quick unity course i was able to understand at least the abseics of C#. This allowed me to be able to code a game in unity. As they were blowing up at the time i wanted to create my own mobile IDE game. I decided to make one of the type were you merge items to make it better and better for ever. I decided that I would make it so that you would merge pigs and they would upgrade in ability. First i created some semi decent sprite modeling for the background and for the pigs. I then created a c# script that made the pigs bounse around from wall to wall. Finaly for the pigs i made the ability for them to be dragged into each other and merge to the next level of pig. I also created some ui menues were you could buy some more pigs. This is when disaster struck. My computer crashed, and I had not fully saved the scene in weeks. This caused all of the UI modeling to go away. Luckely the scripts were still there, but this event would be enught to cause me to take a years break of unity. After the break I came back to this project. This time i was determined to finish it, and in just over a month i was able to complete 3 new ui models, new gameEvent scripts, and the ability to spend money to buy pigs. It was hard to figue out what was happening in the code, becasue at that point my coding was still not greate (not that it was at all perfect now either). I finaly got the project compleated and i continued on my next project, the standing desk. Some of the scripts I created for this project included creaet spawing scripts wich generated a unique position in the board. Merge scripts which searched for the next pigs in the prefab and spawned it. Also I nice looking momentum script which made the pigs bounce around the scene. There was also ways to dynamicly upgrade which pigs cost more than others. I finialy wrote my own custom cross paltfrom saving script so that the game would save between sessions. Sadly i was not able to publish to ios because of the apple developer age restriction, so i published it to the web. It is not made for the web so it does not look great.

Unity Mobile Game

I wanted to create a way to share my coding achievements. So I created a blog so that I could post different thanks I built. The blog was built using node.js and express to get data to the frontend and make it reactive. This worked well, but it's not a perfect solution as it was hard to deploy and it was never finally pushed into production. I initially created it using mongo DB, but as it did not work out with deployment I had to switch over to using MySQL which was not intended for this project as a relational database is a lot different than MongoDB. The main page looked nice and it was made using pure HTML and CSS and using express to make it reactive. This project taught me a lot about the deployment and production processes of apps and how different products and solutions work in different ways. I used this later to create my portfolio which was the better version of this. I had done previous Node.js stuff before so that is why I thought no Node.js would work, but in the end, no Node.js did not turn out to be a good solution for the project because deploying it was expensive and required a lot of maintenance. I wanted to continue working on other projects and was looking for a solution that required less maintenance so that is why you cannot find a live demo and why the MySQL database no longer exists. One of the problems I ran into was the Web hosting provider I was using was not great for this type of application. It was hard getting SSL certification and it made it hard to push the app into deployment. I did learn a lot about user authentication and encryption during this process even if some of the backend security measures were not all that secure.

In the early pandemic along with coding I was playing alot of video games, namely minecraft. There was one server that I played on alot: Hypixel. It was a game that simulated a fanticy version of relaity were you levaled up and unlocked new weopens and powers. The game revolved around a in-game currency. This money could buy swords, bows, and all other types of fun things. You could sell and buy things on a action house. You could also buy items directly from people which tended to be more expensive than fighting for it in an auction. There were some extream examples of this were items would go for millions less than what they should have. Theese deals were hard to find though as the UI in the game did not have an easy way to sort this, so you had to manualy go through millions of pages. My idea: create a website were it showed underpriced autions and how much you could make by selling it derecly. The game had a very open and well made API. I used this api to first write a test version of this in python becasue i knew the language well and could make more complated programms than i could in Javascript like what was used in the browser. First I made an API call to the auctions to see the price of all items. I then checked all of theese items up againsed the price that the items were going for when you bought them directly ( data gotten from a second API call ). If there was a match I would Take the price that each was going for and calculated the differance. After this was writen i was able to translate it to javascript. Using the javascript object i was able to probogate the data to a html table. This was the only compleated feture of the website, but there was one other that the backend was made, but the frontend was never compleated. This feture being a bazaar (another in game marketplace used to sell commom goods such as food and raw materals such as iron or gold) flipper. The bazaar was a complacated shop. First You could create buy and sell orders. Theese were were you would place your items (incase of a sell order) or your money (incase of a buy order) and you could choose how much you wanted to buy or sell something for. There was also a way to buy and sell things instantly which would compeate the buy and sell orders at whatever they are willing to buy or sell for. This being said there was often a disparity from the price of creating a buy order and the price of creating a sell order. This was caused by people being eager to buy and sell things instantly even if the price is more than what the items are worth. The Simple way that then flipper worked was it would see the differance from the buy and sell orders and calcuate the profit, but it was not that simple. It was not this simple beacause the buy and sell costs could change, so buy the time that your buy order got filled the price for selling the item could have gone under what you bought it for. My solution was to plot the data on a graph and use an average trend over the last 5 orders to calcute were the price will be buy the time that the buy order was created. Then once you know what the price is in the future you can calcute an even more accurate profit prediction. The way I achived this was to create a backend node.js app and enter all of the data into a mysql database. Then when someone wanted to see what the best items to buy and sell were I would query the database and take that data then only view the last 5 order and see the slope that the are moving at based on the time and price. I would then take an everage that the price moves per second. I than took this data and multiplide it buy the time it would take to compleate  ( finding the time it took to compleate the order also took a database of how long it took to compleate each previosu order made and then take the time devided by the quantity to get the time per item. I would then multiply this by the quantity that you wanted to place the order for to get the most profit. )the order and then add this to the current price to get what the price is going to be in the future. I had all of this data in a backend server but I never setup the api to get it to the frontend.

At the very start of the pandemic I started getting really into coding. The first project that started this coin journey was a dice probability calculator. I was playing DND and was amazed by how probability worked and how rolling dice probabilities worked. After reading about how probabilities worked I wanted an easy way to calculate them in my games of DND, so I decided to try to use a skill that I had not used in a while: Coding in python. I still remembered some of the basic syntaxes, and the basics of coding ( such as for and if loops), but did not know much. Luckily this was a fairly easy project and just required some simple computations. Some of the steppes were unnecessary such as finding all probabilities of the dice rolls and then counting how many times each occurrence happened. Instead, I could have just plugged in some formulas such as the one at this link: https://uploads-cdn.omnicalculator.com/images/dice_probability_exact_sum.gif. And repeated the calculation for each side of the dice. I did not do this though becasue even though that is what runs fastest on a computer that is not how humans think about probability. I coded the way that made sense, by calculating every single combination that could happen on the dice. I used this project in my life and it was a good starting project and taught my the fundamentals of coding and some math and probability.
