 In GIOS, the cool thing is that the projects are open-ended. All you have to do is pass a test suite they provided. For Project 1, I did it strictly by the book. For Project 3, I did something very weird and zany to the point where the Autograder actually got confused by my project. Project 4 was my least favorite: it uses gRPC and C++, and I ended up disliking both by the end of it (mostly the C++ API of gRPC, I've used the protocol in other languages successfully).

 My second class at OMSCS was cs-7674, Machine Learning for Trading (**ML4T**). I thought it was... alright? It's mostly just Python stuff, of which I'm very familiar with. I took it alongside [[cs-6200|gios]]. It's kind of like an introduction into data science techniques with a focus on ML. Now I'm not an ML person at all, my undergraduate background is in economics and math, but ML is just statistical models. I came in not knowing much and breezed through the class with said knowledge of statistics.
 
 I'm probably killing my career by saying ML isn't really my cup of tea. Honestly, stocks aren't either, I'm a believer in the Efficient Market Hypothesis and [[stocks|buy $VTSAX and chill]]. I'm more interested in ML from a mathematical standpoint, this class is mostly Applied ML. It'll certainly help you get a job, if that's what you're looking for.

 Credit cards are such a fun system. For me, there's kinda a thrill associated with them — you get access to "free" money for a month, but if you fuck up, you get hit with an exorbitant fine.
 
-Credit cards are a big driver of inequality. The current system is based on rewards being funded through irresponsible borrowers. It's basically a wealth transfer from the poor to the wealthy. On a logical level, I shouldn't really support it. If credit cards rewards were to disappear tomorrow, I wouldn't mourn it.

 You are not alone if you have these questions. There are few trustworthy sources for financial information, with most companies trying to sell some product. You really shouldn't trust me either — instead, I'll do my best to link the sources that further elaborate on my thinking.
 
 I wrote this primarily because I became "the guy" explaining finance to all my friends, and quite frankly, I got tired of copy-pasting the spiel I wrote in my notes app. As such, this is written from the perspective of someone making the median income after graduating college in the United States, which I've guesstimated to be around 50k, give or take. If you're not a college graduate, or you're making more or less, don't sweat; your income is not a reflection of your self-worth, and this advice can be generalized to anyone. Even if you've been working for a long time, you might learn something new from this.

 I think investing in single stocks is pretty much the biggest myth that gets constantly paraded around in "get-rich" type content. Trying to find the needle is not worth your time. Buy the haystack instead.
 
 No one has managed to beat the market consistently for over 30+ years. People can do it in 1, 5, 10, even 20 year spurts, but no one has ever done it for 30 years. Why? The market is the sum of people's decision-making. If someone is successful at decision-making, other people are going to copy them. There's a first-movers advantage, and in the age of the internet, that has functionally evaporated.

-Hedge funds get a lot of praise but don't actually have much to show for it. Indeed, hedge funds aren't designed to grow your money, but to grow your money *consistently*. Sure, on a year-to-year basis you might outperform the S&P in a given year, but why care about that? Your goal is to grow your money over a long period of time, not to withdraw it on a year-to-year basis. You probably work a job, earn your money through there. They also charge a ridiculous fee, so even if they are growing your money, they're likely taking a huge chunk of it into their own properties.

 I have a Proxmox server with an RTX 4090. I want to share the GPU across multiple lightweight Linux Containers (LXCs), of which they might share them with Docker containers, which could theoretically share... whatever, you get it. I want access to `nvcc` on LXCs for development. I also want access to the drivers so applications that use hardware acceleration (such as [Jellyfin](https://github.com/jellyfin/jellyfin)) can... accelerate.
 
 This is a little bit more of a convoluted process than it may seem like. It involves messing with the kernel, building kernel modules, passing through drivers, and downloading multiple packages, but in the end, you get a GPU that can be used in multiple contexts avoiding the overhead of virtualization, with all the upside of containerization and isolation.
 
 > [!info]
-> If you can avoid it, don't install CUDA on your host or LXCs. You should use devcontainer ecosystem and develop inside a docker container, pulling [`nvidia/cuda-devel`](https://hub.docker.com/r/nvidia/cuda/) for `nvcc` access, and you *should* do this to pin your dependencies. However, you *will* need to have the corresponding drivers installed on the host and any additional layers of isolation. This guide includes the installation of drivers, you can skip the CUDA stuff if it's not relevant.

-Here's a fun fact: NVIDIA releases CUDA releases separately from their gaming/workload drivers, but the latter drivers may sometimes be ahead of their CUDA-based drivers. This can lead to some *fun* (author's note: horrible) scenarios. NVIDIA does not directly publish what version of the driver is associated with a CUDA release, you need to figure it out yourself. *woohoo!*
