Currently debating between #100DaysOfMusic or #100DaysOfIndieWeb for my #100Days project.

This sounds like a really great challenge either way! I am rooting for #100DaysOfIndieWeb because I learn so much about #IndieWeb from your stuff.

post 2017-01-01-commitments
2017-01-01-commitments are implementation and launch commitments publicly made by the IndieWeb community to ship on their personal sites by 2017-01-01 00:00 local time.

My 2017-01-01 #IndieWeb commitment is to improve the way I handle files and images to speed up both posting and pageloads for my site.

Configuring Woodwind with imageproxy

A couple of days ago I wrote up a set of instructions for setting up a self-hosted copy of Woodwind with nginx and upstart. Since then I noticed that many images were broken on the feeds I was looking at - a common problem when a site that is served with HTTPS is displaying images and other content from another site that is served with HTTP.

Broken images are so 90s. But, like, sad 90s.

I noticed that the main site was serving images through special URLs like:

Looking in the source code, I found that Woodwind has support for image proxies, which are neat little services that can help serve remote HTTP content over HTTPS, resize images on the fly, and more.

I'd been meaning to set up one of these services for my own site, so this seemed like a good time to jump in!

Since my server already has Go I choseΒ Will Norris' imageproxy, which has a similar deployment setup to how I am already running Woodwind: Upstart manages a standalone process and nginx acts as a proxy to pass along requests.

Installation was fairly simple, once I had my GOPATH set up correctly:

go get

For running a persistent service, Will has an example Upstart configuration, which I modified a bit and placed in /etc/init/imageproxy.conf:

description "Image Proxy server"
start on (net-device-up)
stop on runlevel [!2345]

exec start-stop-daemon --start -c www-data --exec /home/imageproxy_user/go/bin/imageproxy -- \
    -addr localhost:4593 \
    -log_dir /var/log/imageproxy \
    -cache /var/cache/imageproxy \
    -signatureKey @/etc/imageproxy.key

Before starting up the service, there were a few extra steps:

Create /var/log/imageproxy and /var/cache/imageproxy and make sure they are owned by the www-data user.

Create the "signature key" in /etc/imageproxy.key. This is used to authorize each image request so that random folks can't proxy random stuff through your imageproxy. I used the command line openssl tool for this, with an extra pass through awk to remove the newline character that openssl spits out.

$ sudo openssl rand -base64 42 | awk 'BEGIN{ORS="";} {print} > /etc/imageproxy.key

I also made sure that /etc/imageproxy.key was owned and readable by www-data and no other user.

I could then start up the server with:

sudo start imageproxy

Next it was time to configure nginx to send proxied image requests along to imageproxy. I opened up the nginx woodwind.conf file that I had created and added a new location block:

location ~ ^/imageproxy/ {
# pattern match to capture the original URL to prevent URL
# canonicalization, which would strip double slashes
if ($request_uri ~ "/imageproxy/(.+)") {
set $path $1;
rewrite .* /$path break;
proxy_pass http://localhost:4593;

After restarting nginx, requests to would be forwarded to the imageproxy server.

Finally, it was time to configure Woodwind to use the proxy. I opened up woodwind.cfg and added two lines:

IMAGEPROXY_URL = '/imageproxy'
IMAGEPROXY_KEY = '...' # the contents of /etc/imageproxy.key

A quick restart of the Woodwind service, a browser refresh and I have images aplenty!

Thanks for reading! I hope this little HOWTO was useful. I look forward to more fun with imageproxy in my IndieWeb adventures. How might you be able to put imageproxy to use?

Self-Hosting kylewm's Woodwind Indie Reader

One of my favorite aspects of the IndieWeb community is that when you get things "right" with your website, you often get a bunch of fun interoperability with other IndieWeb-compatible websites "for free". For example, the Micropub standard lets you use lots of different clients to post to your own site, and the Webmention standard lets sites notify one another of things like comments, event RSVPs, etc.

Fundamental to having these technologies work well together is microformats2 (mf2), a lightweight way of marking up "structural information" in HTML so that a machine can make (some) sense of the information, such as the name, url, and photo of the author, hints on the important pieces of content in a page, etc.

Getting these things "right" on my own website led me to look for a "Reader" that would make use of the mf2 data and attempt to display it in a meaningful way.

One of the popular readers I saw talked about in the #IndieWeb chat was Woodwind. It was easy to get started by logging in with my own website and then subscribing to my own site to get all my h-feeds, h-entrys, h-cards, etc. in a row. Recently, the hosted version of Woodwind at was down for a few days, so I set out to host my own.

Initial Setup

Thankfully, Woodwind is on GitHub and the Installation instructions are pretty good for getting started. Since I already had a server with the expected dependencies (Python3, PostgreSQL, and Redis), I was able to get a test site up and running in a few steps:

  1. clone the git repo
    git clone
    cd woodwind
  2. create Python3 virtualenv and activate it
    virtualenv --python=/usr/bin/python3 venv
    source venv/bin/activate
  3. install the required Python libraries with pip
    sudo apt-get install python3-dev
    pip install -r requirements.txt
  4. as the postgres user, create the woodwind database and the database user that would access it

    $ sudo -u postgres createdb woodwind
    $ sudo -u postgres psql woodwind
    woodwind=# create user woodwind_user with password '...'
  5. copy woodwind.cfg.template to woodwind.cfg and edit it up

    SECRET_KEY = '...' SERVER_NAME = '' SQLALCHEMY_DATABASE_URI = 'postgres://woodwind_user:DB_PASSWORD@localhost/woodwind'

  6. run the script
    • at this point I discovered a typo in woodwind/ that was throwing errors - a missing parenthesis. once fixed, this ran fine.
    • I've created a pull request for this, so kylewm can merge it back in eventually.
  7. finally, use uwsgi to run the demo version
    uwsgi woodwind-dev.ini
  8. visit localhost:3000 in my browser and I could see that woodwind was running!

This had me off to a very good start, but I wanted to be able to visit my copy of Woodwind from anywhere using a public domain name, protect my activity from eavesdroppers on the network with HTTPS, and have Woodwind up and running reliably across server crashes, reboots, etc.

Setting up Woodwind with uwsgi, Upstart, and nginx

Woodwind is an application written in Python. uwsgi is an application server that can run that code on demand, efficiently. It is possible to run uwsgi by hand as we did above, but I wanted the service to be started and managed automatically by the operating system.

I run an Ubuntu server with the upstart process manager. So, I created an upstart configuration for Woodwind at /etc/init/woodwind.conf:

description "woodwind uwsgi instance"
start on runlevel []
stop on runlevel []
setuid woodwind_user
setgid woodwind_user
chdir /home/woodwind_user/woodwind
env LC_ALL=C.UTF-8
export LC_ALL
env LANG=C.UTF-8
export LANG
. venv/bin/activate
uwsgi --ini woodwind.ini
end script

With this, the uwsgi server should start up on boot to serve Woodwind, and I can now manage woodwind from the command line. For example:

$ sudo start woodwind woodwind start/running, process 14104 $ status woodwind woodwind start/running, process 14104 $ sudo restart woodwind woodwind start/running, process 14246 $ sudo stop woodwind woodwind stop/waiting

Since I wanted to use HTTPS to protect my activity on Woodwind from network eavesdropping, I used Let's Encrypt and their certbot tool to create an SSL certificate for my domain. The steps are:

  1. Create a DNS entry for to point to the public IP address of my server. This may take some time to propagate and certbot won't work until it has taken effect.
  2. Install certbot
  3. Stop nginx from running, temporarily.
  4. Use certbot to issue a
    ./certbot-auto certonly --standalone \
      --standalone-supported-challenges http-01 \

This resulted in an SSL certificate and key pair that I could use to encrypt traffic to this domain.

Next up, I need something to actually handle the HTTPS requests and pass them along to uwsgi. I used nginx for this because I was already using it on this server. In my nginx config directory, I created a woodwind.conf file:

upstream woodwind {
server unix:/tmp/woodwind.sock;
upstream woodwind_wss {
server localhost:8077;
server {
listen *:80;
server_tokens off;
ssl on;
ssl_certificate /etc/letsencrypt/live/;
ssl_certificate_key /etc/letsencrypt/live/;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;
ssl_session_cache shared:SSL:10m;
ssl_dhparam /etc/ssl/certs/dhparam.pem;
root /home/woodwind_user/woodwind;
access_log /var/log/nginx/woodwind_access.log;
error_log /var/log/nginx/woodwind_error.log;
location /_updates {
uwsgi_pass woodwind_wss;
location / {
try_files /woodwind/static/$uri /frontend/$uri @woodwind;
location @woodwind {
uwsgi_pass woodwind;
include uwsgi_params;
uwsgi_buffering off;

This nginx configuration has some things worth noting:

  • In addition to running a process that answers regular HTTP requests on a unix socket at /tmp/woodwind.sock, Woodwind also runs a service that answers WebSocket traffic at localhost:8077 for nifty features like live updating the page in your browser when a feed is updated.
  • Woodwind serves some static files out of its /woodwind/static folder as well as the /frontend folder. I needed to install the dependencies in /frontend using npm:
    $ cd frontend
    $ npm install --nodev

After all this setup, I restarted nginx and was able to visit Woodwind in my browser!

I am happy with my setup so far. I am not quite sure yet if I did the WebSockets configuration correctly, but in general things seem to be working alright. I hope this information is useful to someone down the road, even if it is just future me.

Homebrew Website Club Baltimore is just two days away!

Come work on your website alongside other folks who are doing the same!
