Howto: IPFS on Fedora 34

I like IPFS a lot; for many reasons.

  • They're distributed.
  • Support newer technologies (quic, for example)
  • Enable a descentralized web.

Besides that, it's a pretty convenient app to use once you get the hang of it. You can either go full CLI on it or just user it from the …


Reboot

Yeah, so my blog is back!

I've finally found a way to publish the content I want to publish; in a friendly way.

HowTo: Fixing Dovecot 2.2 in CentOS 7.2

Advertencia

If you update dovecot on CentOS 7, it will brake! You need to update one of the config files in order for it to keep working.

# /etc/dovecot/conf.d/15-mailboxes.conf
...

namespace inbox {
    ...
    inbox = yes
    ...
}
...

So, basically, you need to add inbox = yes within the inbox namespace.

So, how do we do this? Easy, we use a …
