IPFS configuration with NAT

IPFS (here, referring to go-ipfs or kubo) already supports NAT environments, but there is a lack of documentation explaining this, leading to difficulties in configuration for many users.

Below is an configuration example for supporting NAT environments in IPFS.

How to accelerate video trancoding (FFmpeg) in Mastodon

How to accelerate video trancoding (FFmpeg) in Mastodon

Let's build a remote video transcoder (FFmpeg) for Mastodon!

This post may be outdated. Please check https://github.com/gnh1201/topic-activitypub/blob/main/ffmpeg.md

Why?

Whenever there were incidents or similar events on X (formerly, Twitter), such as on July 1st, the Sidekiq queue in Mastodon would expand, resulting in latency exceeding 10 hours. However, no matter how many photos or videos were being exchanged, it seemed unreasonable in a network where text communication was the primary focus. Eventually, when I disabled all multimedia processing-related features, the latency dropped to zero.

Launch Chromium with API Keys on Mac OS X and Windows

Sometimes you need to use API Keys to use things like the Speech API. And then you Google a bit and follow all the instructions. But the Chromium Project's API Keys page does a not-so-great of explaining how to do this, so I will.

  1. Download Chromium.
  2. You'll notice a yellow disclaimer message appear as a doorhanger: Google API Keys are missing. Some functionality of Chromium will be disabled. Learn More.
  3. Clicking on that link takes you to the confusing API Keys docs page.
  4. If you aren't already, subscribe to the chromium-dev@chromium.org mailing list. (You can just subscribe to the list and choose to not receive any mail. FYI: the Chromium project restricts the APIs to those subscribed to that group - that is, Chromium devs.)
  5. Make sur
