musicForProgramming("IPFS!");

Listen to music while you program, streamed via the peer-to-peer technology IPFS. The music comes from musicforprogramming.net, and has been carefully chosen to maximize concentration by providing just the right amount of interest to occupy the parts of your brain that would otherwise be left free to wander and lead to distraction during your work.

This web page was stumbled together by @jilleJr in Visual Studio Code. It is a dApp port of the wonderful musicforprogramming.net, rewritten in Svelte in the plan of hosting it IPFS.

This site was originally knocked together by Datassette in SublimeText. Episodes are faffed with using iZotope Ozone and Adobe Audition to maintain comparable loudness and frequency presence between episodes.

Geo-replications

The dApp is pinned to multiple services to allow improved throughput and discoverability:

• my own VPS, hosted in Frankfurt, Germany.
• https://pinata.cloud/, replicated in Frankfurt, Germany and New York, USA.
• https://infura.io/, uncertain geographical location, but DNS records on their gateway suggests eastern US

Limitations

1. Requires IPFS. Adding js-ipfs is on the roadmap (#3) and hosting it as an alternative via plain HTTP, but for now you can only access the site via IPFS.

2. Uses Ogg Vorbis as audio codec. This is mostly supported today, with some exceptions:

   • Internet Explorer (what a shocker)
   • Safari (allegedly works with OS X v11.3 or higher though)

   Source: https://caniuse.com/ogg-vorbis

   This site uses Ogg Vorbis because it trimmed down the size of the audio from 7 GB to 3 GB. I'm not including the .mp3 files to reduce the bloat from the IPFS object, but if you really want back .mp3 then please tell me in a new issue.

3. Slow. Not many users as of yet, and so the centralized musicforprogramming.net is way faster. Though this will hopefully get resolved the more users we get to allow more peers.

   In the meantime, you can increase the throughput by following the "Speeding up connection" guide below.

Speeding up connection

Seeding peers

:warning: I have disabled this due to limited resources. IPFS currently takes up way more memory than I'm comfortable with, and is hogging up my VPS.

It's probably configurable and all that, but I ain't got the energy to delve deeper into the subject right now.

Disabling TCP connections on your local node

IPFS will happily connect up to 300-600 other peers, with one TCP connection towards each. Unless you have a super computer and super-duper router, and even super-er-er Internet connection, then this can stress out your router and even your PC's OS. The limit on parallel TCP sockets is questionably low.

But there's an alternative: QUIC over UDP!

QUIC over UDP is enabled by default, but to make your computer happier you can disable all TCP connections. The drawbacks are that not all peers support the UDP/QUIC IPFS connection type. But when comparing "somewhat usable with QUIC" vs "locks up my home's internet so I can't even google why it's happening", the former takes precedence.

Edit your IPFS config by changing the following values:

 {
   "API": {
     "HTTPHeaders": {}
   },
   "Addresses": {
     "API": "/ip4/127.0.0.1/tcp/5991",
     "Announce": [],
     "Gateway": "/ip4/127.0.0.1/tcp/9123",
     "NoAnnounce": [],
     "Swarm": [
-      "/ip4/0.0.0.0/tcp/4001",
-      "/ip6/::/tcp/4001",
       "/ip4/0.0.0.0/udp/4001/quic",
       "/ip6/::/udp/4001/quic"
     ]
   },
   "AutoNAT": {},
   // ...
   "Reprovider": {
     "Interval": "12h",
     "Strategy": "all"
   },
   "Routing": {
     "Type": "dht"
   },
   "Swarm": {
     "AddrFilters": null,
     "ConnMgr": {
       "GracePeriod": "300s",
       "HighWater": 300,
       "LowWater": 50,
       "Type": "basic"
     },
     "DisableBandwidthMetrics": false,
     "DisableNatPortMap": false,
     "EnableAutoRelay": false,
     "EnableRelayHop": false,
     "Transports": {
       "Multiplexers": {},
-      "Network": {},
+      "Network": {
+        "TCP": false,
+        "Websocket": false
+      },
       "Security": {}
     }
   }
 }

The first section of removals disables incoming connections to use TCP. (Docs: Addresses.Swarm)

The latter section of changes will disable Websockets (which uses TCP) and pure TCP connections for when your local node connects to other peers. (Docs: Swarm.Transports.Network)

Make sure to restart your IPFS node for the changes to take effect. For IPFS Desktop, that would be to click the system tray icon of IPFS and then selecting Restart. For IPFS in Brave, just restart the browser (all windows must be closed).

Why does this repo exist

1. I wanted to try developing with Svelte
2. I wanted to try publishing to IPFS
3. I want to use more dApps in everyday life, and this is a :100: everyday app for me

Difference with musicforprogramming.net

Development

Setting up dev env

1. Install Node.js (v14 or greater) and download all code dependencies using npm:

   $ npm install
   

Download audio files

Too many files to be hosted in Git, even in Git LFS. They take up ~7GB at the moment.

Can be downloaded via IPFS:

$ ipfs get QmNiXZvueoyofKZoVEfs2kxWnVEe83Mc5UtyjV69B8ZB8q -o public/audio
Saving file(s) to public/audio
 5.00 MiB / 2.91 GiB [>---------------------------------------------------]   0.07% 38m45s

If the download is unbaringly slow, then you may be able to speed up the process by regenerating the .ogg audio files by downloading the majority of the .mp3 songs via BitTorrent (ex: via WebTorrent) and then converting them by hand using ffmpeg:

1. Download https://musicforprogramming.net/MFP_01-52.torrent. That only provides the songs 01 to 52.

2. Songs 53 to 62 will have to be downloaded manually from the webpage https://musicforprogramming.net/.

3. Convert all files from .mp3 to .ogg using ffmpeg:

   $ for f in *.mp3; do echo "$f"; ffmpeg -i "$f" "${f/.mp3}.ogg" -hide_banner -loglevel error -stats; done
   music_for_programming_10-unity_gain_temple.mp3
   size=    1327kB time=00:01:48.00 bitrate= 100.6kbits/s speed=44.2x
   music_for_programming_11-miles_tilmann.mp3
   size=     393kB time=00:00:29.07 bitrate= 110.8kbits/s speed=30.4x
   music_for_programming_12-forgotten_light.mp3
   size=     175kB time=00:00:13.10 bitrate= 109.3kbits/s speed=29.5x
   ...
   

4. Place the converted songs in public/audio/*.mp3.
