How to close a channel on Freenode when migrating to Libera

Run /msg NickServ LISTCHANS to see what permissions you have in what channels.

For each channel you have +s, +R and either +o or +O or +t permissions in, run:

/msg ChanServ OP #channel
/msg ChanServ SET #channel TOPICLOCK OFF
/msg ChanServ TOPIC #channel We have moved to irc.libera.chat

Detecting the real IP of a Cloudflare'd Mastodon instance

NB: This will not work for instances that proxy outgoing requests!

Reading the docs

I wanted to find a way to detect the real IP address of a Mastodon/Pleroma/Misskey/etc instance hosted behind Cloudflare. How to do that? Well, it's federated, which means I can probably get it to send a request to a server of mine! And how to do that? I tried reading the ActivityPub spec. The following caught my attention:

Servers should not trust client submitted content, and federated servers also should not trust content received from a server other than the content's origin without some form of verification.

Это логи чата, а не протокол какого-то собрания, так что просьба шуточки про JS
близко к сердцу не принимать. Кроме того, речь идёт о JVM, Erlang VM, браузерах,
native, поэтому слово «абстракция» следует понимать как «платформа». —Minoru

Из codingteam@conference.jabber.ru:

<ForNeVeR> ɹǝɟılʍǝu: смотри что. У JS есть своя семантика (модель памяти,
           выполнения, и проч.). Прямых маппингов на машинную модель у неё нету. 

           JS не зависит от машины. Поэтому, чтобы писать на JS, тебе нужно

Prerequisites : the letsencrypt CLI tool

This method allows your to generate and renew your Lets Encrypt certificates with 1 command. This is easily automatable to renew each 60 days, as advised.

You need nginx to answer on port 80 on all the domains you want a certificate for. Then you need to serve the challenge used by letsencrypt on /.well-known/acme-challenge. Then we invoke the letsencrypt command, telling the tool to write the challenge files in the directory we used as a root in the nginx configuration.

I redirect all HTTP requests on HTTPS, so my nginx config looks like :

This is material to go along with a 2014 Boston Haskell talk.

We are going to look at a series of type signatures in Haskell and explore how parametricity (or lack thereof) lets us constrain what a function is allowed to do.

Let's start with a decidedly non-generic function signature. What are the possible implementations of this function which typecheck?
