Set up HSTS in nginx
HSTS can dramatically reduce the efficacy of MITM attacks by telling the browser to only talk to the site over HTTPS.

Add a fallback stream
It's unlikely, but MPD can go wrong. Adding a fallback stream to the /mpd-*.{mp3,ogg} mountpoints would at least prevent the radio from going totally dead until I fix things.
Ideally, the source of this stream should not be another MPD instance. Just something simple that can loop a single audio track.
The 404 music would work fine.
This is a server configuration change and so implementing it would kick everyone off the stream.
Set Referrer-Policy header
https://scotthelme.co.uk/a-new-security-header-referrer-policy/
This is especially useful when #32 is implemented, which may well leak CSRF tokens into GET parameters (and so the default referrer for any external links.)
strict-origin-when-cross-origin seems like a good default. This sends the full URL when going to the same origin, the origin when going to another origin, and nothing when downgrading from https to http:
This is a server configuration change and so implementing it would kick everyone off the stream.
Vapourwave channel?
Currently got a few Vapourwave albums on everything, worth having a dedicated channel?
Improve very inefficient use of MPD clients
backend.py opens a new MPD client every time a playlist is requested, which is every 15 seconds per listener. This is very inefficient: it should open the clients when it starts, and re-open them if they drop for any reason, returning the current error if reconnection fails.
Not so great:

File list links return 404 Not Found
The playlist links on the site player (https://lainon.life/file-list/everything.html, https://lainon.life/file-list/cyberia.html, etc) are currently returning 404 errors instead of file lists.
Display donate page inside modal window
I think it would make more sense to have the donate page display inside a modal window instead of having it as a separate .html page. So basically like https://lainon.life/#schedule. Also the stream wouldn't be interrupted that way. The donate.html page could be kept for external linking purposes.
Make space pause/play
New track/album request form
There's a feedback thread on /music/, but something directly on the site would be nice as well. Maybe this would work best as a generic comment form, with suggested topics (eg "music you want").
Steps:
- Implement a pretty form as an HTML page.
- Implement the backend functionality. The
upload_voicefunction should be helpful. - Link from the radio page.
Websockets instead of AJAX
Currently there's a buttload of AJAX requests. Every client is frequently talking to (1) Icecast, for the number of listeners and channel description; and (2) backend.py, for the current playlist.
All of this data is something which changes relatively infrequently, so it would be nice to use something push-based rather than pull-based.
Steps:
- Look into Python websocket server libraries
- How would this work with Python's poor concurrency?
- How would this work with Flask? If it doesn't, another backend service would be needed.
- This would require restarting nginx, kicking everyone off the current stream again...
- Maybe it would be better to rewrite the backend in (eg) Haskell, which I know how to do this in, and which has (a) good concurrency and (b) good libraries.
- Reimplement the playlist client AJAX with websockets.
- Talk to Icecast in the backend, and replace that client AJAX with websockets too.
- Is there something other than pull-based HTTP which can be done here for the Icecast communication?
Require javascript?
Currently index.html works for both javascript and non-javascript users, although the non-javascript behaviour is greatly degraded.
This leads to significant complication in the code, however. It also means that it's hard to implement features like (eg) the requests form being a modal window with a javascript submission, rather than a separate page with a regular POST submission. It would be nice to keep everything on one page, to avoid navigating away from the audio stream.
A <noscript> tag could be used to point people to the raw streams at /radio/.

That shouldn't happen.
Refresh playlist at end of song
The playlist only updates every 15 seconds, so the user will be up to 15s into the next song when the current one ends. Not terribly great UX.
http-backend service was hanging for some reason
I was having difficulty loading the site and noticed that there had been no journalctl entries for two hours. Attempting to load the playlist from another machine hung:
--2017-10-14 14:03:51-- https://lainon.life/playlist/cyberia.json

I did not try to load the playlist locally, so I don't know if this was an nginx or a http-backend issue.
Restarting the service fixed it. Here's the journal showing the latest requests received before the restart and the restart itself:

...
As there should be a request to the playlist every 15 seconds, at least, it's very suspicious that there were apparently no requests for two hours. This means that something was going wrong processing all requests: either nginx failing to deliver them (and just hanging internally for some reason) or http-backend failing to process them.
File list html return 404
Hi 👋
Like #42, now its returning 404 on https://lainon.life/file-list/everything.html, https://lainon.life/file-list/cyberia.html, https://lainon.life/file-list/cafe.html and https://lainon.life/file-list/swing.html
Make the site responsive
I think it would be nice if the site would be responsive.
This is not that important, I guess, most people won't use it on a smartphone.
Nevertheless I think it would be a "nice to have"-feature.
I tend to use the site on the go, on mine, so I would be happy about it. ^^
Lolicore channel?
Got this request:
album: Dancefloor Degrader
url: http://lolicore.ml/DanceCorps/[DCRPS010]%20Goreshit%20-%20Dancefloor%20Degrader/
notes: I think there already is a bit of breakcore/lolicore, but I am not really sure tbh.
I am also not really sure if it is fitting, but I thought I suggest it anyway.
It's a classic lolicore album.
Maybe a breakcore/lolicore channel would be something but I think there aren't enough listeners.
artist: Goreshit
Maybe worth having a lolicore channel?
Allow streaming to any channel
It's currently hard-coded that streaming is to cyberia, which is reasonable as that's the default channel on lainchan.org.
It would be nice to be able to stream to different channels, however. There could even be multiple DJs streaming simultaneously to different channels!
Add a stop button
Currently the pause button, when resumed, causes the player to continue where it left off. It's now behind the stream. Better behaviour would be to just resume from wherever the stream is up to.
Smooth progress bar dont work
Hi 👋
Currently the progress bar is only updated by api requests because the progressFun() function is not defined, maybe the problem is this code;
lainonlife/frontend/js/player.js
Lines 125 to 127 in b3fee61
It was removed in commit 33b11a7#diff-cdb222c1cd0bfd939054445c45f332a61fb3c7b246428b4eec259561b2efbbbf
Incorrect Peak Listeners Count
Something's (potentially) up on icecast's end, stepped through check_status in radio.js and it's working as it should but the listener_peak from status-json.xsl doesn't match what the graph dashboard says.
vs
Custom player widget
The browser widget really doesn't fit in. Just a simple play button, progress bar, and time, of the appropriate colours (eg http://r-a-d.io/).
Notes:
- The current radio page works even if you have javascript, it just has no interactive features and tells you to turn on javascript. That graceful degradation should be kept.
- It even works if you have CSS disabled, but then it looks bad as well.
- The
check_playlistfunction gets the duration and progress of the current track. These can be used to correct the progress bar, with constant-rate advancement happening otherwise.
Favicon
Different passwords for MPD and livestreamers
Currently the same password is used for the /$channel.$ext and /mpd-$channel.$ext streams (although it is a per-channel password). This means a DJ could stream to the MPD mountpoint. It would be better to have different passwords, to prevent this.
This is a server configuration change and so implementing it would kick everyone off the stream.
Vote to skip?
The current playlist is planned hours in advance. I do think that occasionally playing a complete album is nicer than purely global shuffle, but it does mean we can't really have a request form like r/a/dio. The next best thing is a link to vote to skip an upcoming track.
Steps:
- Add an AJAX-powered button to send a "skip track" request to the backend.
- Keep track of number of listeners of the channel.
- Maybe it should only be listeners who are listening via lainon.life, rather than lainchan.org or other sites. Those other people won't be voting.
- The number of listeners on lainon.life can be measured by logging unique IPs over a short time.
- Keep track of number of skip votes.
- Remove the track from the playlist when the skip votes reach a certain proportion of the listeners.
Absolute include paths
Is there a reason why the backend scripts file-list.sh and backend.py are reading files from an absolute path (/srv/http)?
I'm not much of a Python programmer, but I could imagine this causing issues when deploying the application on different kinds of operating systems. Debian for example uses /var/www/html as webserver root.
So basically I'm suggesting using relative paths. That way the web application should be able to run from any directory.
CSRF protection on DJ / Admin pages
The admin actions are particularly bad for this, as they all work with GET requests.
Here's a snippet about CSRF and Flask: http://flask.pocoo.org/snippets/3/
Probably better would be a decorator that checks the params, as that would then work with GET and POST requests.
Change default channel to cyberia
To match the lainchan radio page.
Script support for livestreaming
Fortunately, Icecast makes livestreaming very simple. There's just a little work that needs to be done for it to be seamless.
-
Some sort of schedule on the website. r/a/dio (click "Schedule") just has a box appear with javascript. We can use something like that too, with an appropriate non-javascript fallback.
-
The
playlist_forfunction in backend.py needs to be aware that the playlist may not come from MPD:- For the current track: perhaps a file at a designated location would work; even better would be extracting metadata from the stream from Icecast, if possible, with some fallback.
- The "Last Played" and "Queue" can just be blank.
- The duration of the current track can be unspecified, with
radio.jsandplayer.jsdisplaying that nicely somehow.
-
A script to start a stream:
- Pause MPD
- Turn off the Icecast outputs
- Do whatever needs to be done for
playlist_forin backend.py to know there is a stream
-
A script to stop a stream:
- Unpause MPD
- Turn on the Icecast outputs
- Undo whatever was done to backend.py
The MPD and Icecast configs are not very exciting, but in case they are of use:
icecast.xml:
<!-- There is nothing exciting here. I have set the hostname and passwords, that's it. Everything else is default. -->

For dealing with the MPD outputs, see the python-mpd2 docs.
Deprecate /radio/ route (301 it to :8000)
To avoid an ugly http://lainon.life:8000 URL, the stream is currently proxied through nginx, which has two downsides:
- Any restart of nginx kicks people off the stream.
- This adds SSL overhead.
It would be best to get a second IP, point stream.lainon.life to that IP, and have Icecast listen on stream.lainon.life:80.
This is a server configuration change and so implementing it would kick everyone off the stream.
Set up a staging site
As evidenced by this morning, just checking configuration is syntactically valid and looks reasonable before deploying is a good way to cause downtime.
Fortunately, NixOS containers should make it trivial to run a staging site.
Don't play a full album which has already played in the past 24 hours
There are a lot of albums now, so diversity should be encouraged.
Suggestion: playlist upload feature
it would lower the barrier of entry for people considering djing, this can be done with a vetting procedure or as an auto-dj type thing
Prioritise new albums
Similar to #10 but different.
It would be nice to pick a new album, if there are any, when deciding which one to schedule.
There could simply be a list of which albums have been played, or maybe MPD's sticker mechanism could be used to store that info in its database.
Add a donate page
I got an email from someone wanting to donate for server costs.
This is quite possibly the first ever non-scam email I've got out of the blue offering me money.
