New post: Controlling IP traffic on your webserver

A cool part about having your own webserver is that you get to choose who can visit. When IP addresses try to access sensitive files or aggressively scrape, you can just block them.

Here's how.

brandonrohrer.com/hosting5.html

Block an IP address
The most straightforward way to block and IP address is in the firewall. It is the tool build specifically for this.

To block the address 101.101.101.101, run from the command line

sudo ufw insert 1 deny from 101.101.101.101

This instructs ufw (the Uncomplicated FireWall) to insert a rule at the the top of the list (position 1) to deny all incoming traffic from the address. After running this, no restart of the firewall is needed. The rule is active. (ufw docs

The position 1 is important because in ufw, the first rule that matches is applied. If there was a rule to allow all addresses that started with 101. and that rule came before the deny rule, then the deny rule would never be reached.

While it's possible to block specific ports, or even to block an IP address from seeing particular pages, complex rules and conditions get difficult to analyze very quickly, and can lead to cases where there are loopholes. Use fancy rule combinations sparingly.

Parse logs
In their raw form access logs are technically human-readable, but they are a lot. I found it really useful to do a little parsing to pull out the bits I'm interested in. (I'm working with the default nginx log format, so adjust this according to your own.)

I wrote a script to take advantage of the repeatable structure of these logs to dissect them into their parts. It uses tricks like splitting the log based on brackets and spaces. It productes a pandas dataframe with columns containing the IP address, requested URI, HTTP status code, and every component of the date and time.

If you like dogs and you like horror films, I highly recommend "Good Boy". A great horror film from a dog's perspective. Really refreshing and different, and amazing to see how they shot it with the director's dog, Indy.

Note: nothing bad happens to the dog.

Just discovered the {gm} package, which lets you programmatically create sheet music (and audio!) with #rstats (with MuseScore as the backend) flujoo.github.io/gm/index.html

library(dplyr)
library(gm)

golden <- tribble(
~pitches, ~duration, ~lyric,

"D4", "q", "now",
"G4", "q", "I’m",
"E5", "q", "shin-",

"G4", "q", "like",
"B4", "q", "I’m",
"A5", "q", "born",
"F#5", "q/3*(q/8)", "to",
"G5", "q/3", "be._",
"G5", "h", ""
)

music <-

It's Bandcamp Friday (which means that 100% of your purchases go to me), and I'm releasing a new live album called *I play better when no one's watching*. Soothing ambient music written for an art fellow's reception:

Is this a silly idea or not? Thinking about putting together a simplified and lightweight learning management system (LMS) using #rstats / #shiny / #surveydown

Everything else works, including install.packages("tidyverse"). You may need to install "knitr" to get things to render

Ted Laderas @tladeras.bsky.social · 11d

It was actually a pretty straightforward process:

1. Install gdebi package manager,
2. install positron arm64 deb package.
3. Install R using instructions at R4Pi.org.
4. Install uv using instructions
5. Install Jupyter in project using uv

It's actually going to be my dedicated Obsidian machine, but I thought I'd try to install Positron just to see if I could.

I shared this earlier because I think it is so funny but then I also thought to myself, what advice would I (a learning scientist by background, married to someone who teaches programming) actually give a developer who feels bad reading this? How can you avoid writing this?

A few tips:
