I made a turnip-counter! It reads Super Smash Bros Melee replay data, searches for items pulled by Peach, and records information to a sqlite3 database!
The code looks specifically for items initially owned by me, so the good luck of other Peach players isn't counted:
/// Tokio task to send Peach item records to database worker.
async fn record_items(tx: Sender<DBCommand>, items: ItemLog, game_id: i64, me: Port) -> App<()> {
for (item_id, history) in items {
// only record my turnips
I've been learning about systemd-run:
systemd-run may be used to create and start a transient .service or .scope unit and run the specified COMMAND in it. It may also be used to create and start a transient .path, .socket, or .timer unit, that activates a .service unit when elapsing. If a command is run as transient service unit, it will be started and managed by the service manager like any other service, and thus shows up in the output of systemctl list-units like any other unit. It will run in a clean and detached execution environment, with the service manager as its parent process. In this mode, systemd-run will start the service asynchronously in the background and return after the command has begun execution (unless --no-block or --wait are specified, see below).
I am interested in using systemd-run as a way to start up background tasks, without needing to run a program in tmux. I ran this command to download a [YouTube pl
I'm capturing packets from Final Fantasy 14 and trying to decode some information!
I used ss to see which TCP socket my ffxiv_dx11.exe process was talking to (204.2.229.99:55024)
❯ sudo ss -Otnp | grep ffxiv

I used tshark to capture some packets:
I started diving into the BPF Performance Tools book, and there's so many utilities from the BCC that I wasn't aware of!

I've been doing leetcode, so I wrote some Rust to make fetching the problem description a bit easier, using their GraphQL after capturing some requests as curl commands:
❯ curl https://leetcode.com/problems/contains-duplicate -vL -o/dev/null 2>&1 \
| rg 'set-cookie: csrftoken=([^ ]+);' -or '$1'

My "fetch info" workflow took around 3minutes 26 seconds to complete this morning. It installs nix, gets a shell with cargo and rustc, and then executes cargo run.
I created another workflow to download rustup, run cargo build --release, and to output an artifact:
- name: build netplay-bracket-finder
run: |
cd rust && cargo build --release
- name: upload artifact
uses: actions/upload-artifact@3cea5372237819ed00197afe530f5a7ea3e805c8 # v3
