<p>Thanks to Arpan Dhatt for doing most of the work on this (his blog here: <a href="https://arpan.one/posts/messing-with-gradescope/">https://arpan.one/posts/messing-with-gradescope/</a>)</p>

<p>The reason for this comment (besides the fact that I talk about C# a lot) is due to the fact that C# requires a runtime to be installed for it to work. This is because C# does not compile to native bytecode but rather compiles to an intermediary language (dubbed CIL by Microsoft) and is then translated {{ body_area }}#39;Just In Time{{ body_area }}#39; by the runtime. </p>
<p>This makes running assignments in a docker container where the runtime is not already installed considerably hard. One option we have is that we could just include the runtime in our submission. Sounds easy, right? Well it would be non-trivial to do but due to the fact that the .NET runtime is very large, I wouldn{{ body_area }}#39;t consider this a good idea (Not to mention it{{ body_area }}#39;s super boring). </p>

<p>This one isn&#39;t a <em>personal</em> project, however it is a project that I worked on with a group. We began working on it in February as a part of a
club at UT called Texas Convergent. We recently presented it at the club&#39;s demo day and won the prize for having the best business.</p>
<p>Swole Control is an app that monitors machine usage at a gym on a machine-by-machine level, providing gym goers with information about what machines
are free (this is a major pain point as a gym goer myself). It also provides gym owners with statistics on which machines are most popular, providing
them valuable insights into their business.</p>
<p>To achieve this, we built hardware that consisted of an ESP-32 micro controller and an ultrasonic distance sensor. This hardware is mounted on a gym machine
and it measures the distance to the nearest object. It then sends this measurement to a Rust backend which stores it in a Firestore database (although we had
a fork of it that worked with Postgres). The backend then uses these measurements and compares them to a baseline to determine if there is a user at a machine.
Our mobile app then reads this from the Firestore database (it{{ body_area }}#39;s planned to have it read this from the API to have a better-defined application boundary). The

A little over a year ago, we wanted to make a Discord bot to verify that people on some Discord servers we ran
went to the University of Texas. Initially, it worked by verifying you had a utexas.edu email address and then verifying
some additional information via LDAP. A few months ago Ben found out that using the SaaS survey software that the university uses
(qualtrics), we could have users verify themselves by using the university{{ body_area }}#39;s SSO system. This works because qualtrics can send
data to a webhook when a survey is complete, and it can also require signing in with the university{{ body_area }}#39;s SSO before filling out a survey.

It required that I write a <a href="https://github.com/Verified-Bot/aes-gcm-siv-wasm">wasm wrapper for an encryption library</a>. I wrote almost all the code for this function last year, but
due to a bug in qualtrics, it wasn{{ body_area }}#39;t working properly. It seems that this bug has been fixed and we can start rolling it out.</p>
