Hello people. It's been a while since we voted to migrate this instance to .

Unfortunately, at the moment, we have some issues to migrate the statuses: the only migration tool ( doesn't work with our version of Mastodon. If any programmer has time/will to give a hand, it's welcome.

Another possibility is that I set up the new Pleroma instance on a subdomain and slowly every user can migrate their data at their own pace... Of course, I'm open to suggestions.

I reinvented threading macros in Common Lisp a little bit, this time from the point of view of "what if each binding step was a value of its own?"

And I wrote a sizeable tutorial for them, too.

I've more or less finished Cafe Latte - an implementation of Common Lisp dynamic variables, control flow operators, and condition system in plain Java.

The first physical photo of my that I have seen, next to another Lisp book and the best keyboard that I have seen this year.

My copies are still in transit; I can't wait to see them.

Kudos to Steve Losh for the photo!

So, I'm working on this parallel workflow execution framework in using a implementation (datalevin) as temporary store.

Basically you define a job with some tasks, the relations between tasks and the framework took care to execute them in the right order (topological sorting and so on).

Parallelism and concurrency are achieved with clojure.core.async.

Using datalog as query language gives some help managing jobs and tasks relations: it's almost like having a graph db.

Of course we are going to release it when ready.

I can write about it a little bit more if anyone is interested.

(the Berlin conference on ) is running a survey to figure out what people would prefer for a 2021 summer edition. Please boost!

(Note: I'm not affiliated with the conference, I just think it's great.)

Mastodon - disk space usage 

That's quite surprising, I always thought it was media attachment the major reason for disk space eating. Wll surprise:

mastodon at functional in ~/live 
$ RAILS_ENV=production tootctl media usage

Hi everyone, for a bit of instance transparency: here's the actual list of other mastodon/pleroma instances that are currently block (at different levels) by

  • (suspended)
  • (suspended)
  • - (suspended)
  • (suspended)
  • (suspended)
  • (silenced)
  • (suspended)
  • (silenced)

You can find the differences between silenced and suspended here

I probably found the home timeline issue, let's see in the next hours...

We did it, Reddit! The new Pleroma release 2.1 is out, containing the first ever ActivityPub chat application!

Lots of changes in this one, I'm sure you'll like it!

Hi friends. As you surely have noticed, there were some issues with the instance lately. I'm trying my best to figure out what the hell is wrong with it.

I made some changes tonight, let's see how it goes.

Please, don't be afraid of contact me if you see something strange. You can direct message me or any other way.

There's some ways to contact me on my profile.


"Se soffri di diabete fin dalla tenera età, sei considerato un guerriero, ti guardano con tenerezza quando prendi la tua dose di insulina e trovi comprensione nel prossimo.

Se soffri di depressione fin dalla tenera età, sei considerato un debole, ti guardano con occhi sgomenti se assumi farmaci antidepressivi e trovi giudizio nel prossimo.

Chi soffre di un qualsiasi disagio psichico, infatti, spesso si sente “debole” e trova conferme nella società.

Lo stigma è un termine complesso che include problemi di conoscenza (ignoranza o mis-informazione), di attitudine (pregiudizio) e di comportamento (discriminazione).

Una persona che ha un dolore fisico non esita a contattare un medico; una persona che soffre di un disturbo mentale decide di ricorrere alle cure solo dopo diversi anni, precludendosi la possibilità di stare meglio."

Music / thoughts 

More and more "Mr. Knowitall"-like people nowadays.
Everybody seems to knows how to solve world-wide problems and who is to blame for those.
Strangely, tho, the ones to blame are always someone else.

"They call me Mr. Knowitall
I will not compromise.
I will not be told what to do.
I shall not step aside.

They call me Mr. Knowitall
I have no time to waste.
My mouth it spews pure intellect.
And I've such elegant taste."

Mastodon -> Pleroma adventure 

Looks like old toots (2017) have problems to be serialized by Mastodon, that's what crash the migration...

Mastodon -> Pleroma 

Ok, guys, first issue, looks like the migrator doesn't support Mastodon v3.x.x yet:

Mastodon -> Pleroma 

Guys, I'm making the first migration test, if everything goes smoothly, I'm planning to do the full migration tonight.
