i think you could develop a pretty good high school steam curriculum just around the concept of the spectrogram. fast fourier transforms, formants in recorded speech, audio compression. it's all there.

spectrograms! i just think they're neat

(this thought brought to you by me trying to figure how how to explain Ohala's "frequency code" hypothesis of sound symbolism in language to someone for whom "second formants" and "high-frequency consonants" might not make intuitive sense and it would be helpful to just be able to show a spectrogram to everyone but what if they've never seen a spectrogram before?)

(brought to you by my cat being annoyed and disturbed at my attempts to produce fricatives with various frequencies and bandwidths)

@aparrish I once saw Bernie Krause give a talk on using spectograms to demonstrate how animals and insects communicate. He makes natural recordings that he calls biophanies. Spectograms make it obvious how they choose different frequencies and take turns, in order to be better heard.

Friend Camp

The decentralized web is about trust. You should only join Friend Camp if you personally trust Darius Kazemi with your social media data. You probably only have that level of trust if we are IRL friends or have been internet friends for a long time. Generally speaking this is a small, closed community. In the end, Darius is the arbiter of what is allowed here. If you don't have a good idea of the kind of behavior that flies with Darius, again, you probably shouldn't join this instance. In the interest of specificity, we do have a code of conduct and privacy policy which you should read.

Friend Camp features several modifications that were requested by our users.

  • you can log in via any subdomain, which means you can log in to multiple accounts in the same browser session (for example, log in once on friend.camp and then as another user on alt.friend.camp)
  • they are no longer called "toots", they are now "posts"
  • if you have a locked account and you get a follow request, a reminder appears under your "post" button (on normal Mastodon mobile it is otherwise buried in a sub-menu and you might not see it for a long time)
  • the emoji dropdown is a neutral smiley face instead of the cry-laughing smiley
  • @mentions are rendered as "@user" for a Friend Camp user and "@user@domain" for remote users. This helps clear up when you follow two people who have the same username on different servers.
  • there is a "never ask me again" checkbox on the confirmation for clearing your notifications -- more info here
  • images in a CW'ed post are collapsed behind the CW. When you expand the CW, you can see the whole image immediately. more info here
  • When an mp3 link is in a post, we also embed an inline mp3 player. git commit here
  • 500 characters of profile text git commit here, requested by @deerful

Important Bit from the Privacy Docs

If you want decent privacy (the info doesn't leave this server), the only way to do that is to set your account to private, only accept friend requests from other friend.camp users, and only ever @ mention other friend.camp users. Once you start talking to people on other servers, all bets are off. Any private message you send to someone on another server could be looked at by the admin of a different server. This is kind of like email: if you are on a private email server, and you send an unencrypted email to a gmail account, congrats, Google now has the content of that email. But also, you do this every day, so, hey. The internet!
