Today i got hit by this accessibility issue on my site. Low contrast links are not distiniquishable. I had not seen this error title before it was new to me, maybe I have bad memory or maybe it’s new to me.
I ended up dropping the background color of the site down a notch as I didn’t
really care for the semi-dark brown anyways. I’m liking the near black
bg-zinc-950 much better now.
Now I got that 100 A11y score in lighthouse.
Today I discovered the Urllink function in bash from the ujust tool from
ublue.it. Seems like a cool trick, but might not work
everywhere.

## Function to generate a clickable link, you can call this using

# echo "${url}"
function Urllink (){
URL=$1
TEXT=$2
# Generate a clickable hyperlink
printf "\e]8;;%s\e\\%s\e]8;;\e\\" "$URL" "$TEXT${n}"

I’ve been debugging a cloudflared tunnel issue in my homelab all day today, and getting really frustrated. My issue ended up being that it was running twice, once without the correct config file and another with it. I believe that cacheing may have compounded the issue.
In yesterday’s post I setup a cloudflared tunnel on my ubuntu server to expose applications running on the server to the internet. I’m setting up a new server and running cloudflared in its own vm.
setup cloudflared tunnel on ubuntu
dig subdomain.example.com
traceroute subdomain.example.com
export CLOUDFLARED_TUNNEL_ID = "my-tunnel-id"
cloudflared tunnel list
cloudflared tunnel info $CLOUDFLARED_TUNNEL_ID
I run a cloudflared tunnel on my ubuntu server to expose applications running on the server to the internet. I’m setting up a new server and running cloudflared in its own vm.
sudo wget https://github.com/cloudflare/cloudflared/releases/latest/download/cloudflared-linux-amd64 -O /usr/local/bin/cloudflared
sudo chmod +x /usr/local/bin/cloudflared
Now setup the config directory. For the systemd service to work, the config
file needs to be in /etc/cloudflared. I like to give my user rights to edit
the config file without being sudo, we will do that here by creating a group
cloudflared, add ourselves to the group, give ownership of /etc/cloudflared
to the group, give group write access to the directory, and refresh groups.
sudo mkdir -p /etc/cloudflared
sudo groupadd cloudflared
sudo usermod -aG cloudflared $USER
sudo chown -R root:cloudflared /etc/cloudflared
sudo chmod g+w /etc/cloudflared
newgrp cloudflared
Now we can log into the domain zone with cloudflared.
cloudflared tunnel login
This will give a url, follow it in a browser to log in.
cloudflared tunnel create <NAME>
mv ~/.cloudflared/cert.pem /etc/cloudflared/cert.pem
mv ~/.cloudflared/<tunnel-id>.json /etc/cloudflared/<tunnel-id>.json
Now setup config. For the systemd service to work, the config file needs to be in /etc/cloudflared. The config that I have provided below will expose localhost:8000 to tester.example.com
export CLOUDFLARED_TUNNEL_ID=$(ls /etc/cloudflared/*.json | xargs -n 1 basename | sed 's/\.json$//')
mv ~/.cloudflared/${CLOUDFLARED_TUNNEL_ID}.json /etc/cloudflared/${CLOUDFLARED_TUNNEL_ID}.json
mv ~/.cloudflared/cert.pem /etc/cloudflared/cert.pem
echo "
tunnel: $(CLOUDFLARED_TUNNEL_ID)
credentials-file: /etc/cloudflared/$(CLOUDFLARED_TUNNEL_ID).json
ingress:
- hostname: tester.example.com
service: http://localhost:8000
- service: 'http_status:404'
" >> /etc/cloudflared/config.yaml
Now to get a dns record for tester.example.com to point to the cloudflared tunnel.
cloudflared tunnel route dns $(CLOUDFLARED_TUNNEL_ID) tester.example.com
Now install the systemd service.
sudo cloudflared service install
sudo systemctl status cloudflared.service
# if its not running
sudo systemctl start cloudflared.service
I’ve been playing with 3d printing some items through the slant3d api. I’ve been pricing out different prints by running a slice request through their api.
I’ve been using uv for project management. It’s been working well for quick projects like this while making it reproducible, I’m still all in on hatch for libraries.
mkdir slantproject
cd slantproject
uv init
uv venv
. ./.venv/bin/activate
uv add httpx rich python-dotenv
You will need an api key from the slant api, which currently requires a google account and a credit card to create.
# .env
# replace with your api key from https://api-fe-two.vercel.app/
SLANT_API_KEY=sl-**
Then you can run the python script to price out your print. I’m not exactly sure how this compares to an order, especially when you add in different materials.
from dotenv import load_dotenv
import httpx
import os
load_dotenv()
stl_url = ''
api_key = os.environ["SLANT_API_KEY"]
api = httpx.Client(base_url="https://www.slant3dapi.com/api/slicer")
res = httpx.post(
"https://www.slant3dapi.com/api/slicer",
json={"fileURL": stl_url},
headers={"api-key": api_key, "Content-Type": "application/json"},
timeout=60,
)
print(res.json())
