After getting rid of the crappy UI and installing LineageOS on my Redmi Phone, I was still not satisfied. Mainly because I am using WeChat too frequently, and it is kinda addictive and time-wasting. Those

Today I decided to play around with the BSD distros. I have used many Linux distros and found they are pretty much alike, no big difference anyways except for package managers. Anyways, I hopped on

Recently, the idea of self-hosting was so intriguing that I decided to code a full-stack video platform. There are many Object Storage providers, including Amazon AWS, Akamai, Digital Ocean, Cloudflare, Alibaba Cloud. Nearly all of

I've failed countless times while experimenting with different phones and operating systems. Unlike computers, which have a universal architecture, each phone possesses its unique structure. This makes installing operating systems on them exceedingly challenging. Furthermore,

There are 2 kinds of estimator for Policy Gradients, full trajectory and and "reward-to-go" We run the two configs on Cartpole with different parameters, specifically, rtg means reward to go, na means normalizing the advantages.

We run imitation learning and Dagger based on expert policies. In this experiment the expert policy is directly sampled out from a trained Neural Network, so Dagger differs from real world applications in that it

Setting up and configuring Raspberry Pi OS can be a streamlined process by using chroot on a different machine. This guide will walk through the steps to prepare your Raspberry Pi SD card on a

So grub is basically a bootloader to start the system. The point here is I've been using grub for almost a year now without a deep understanding. Grub boots the system by using grub shell.
