The Pagure Debian package is now orphan

As promised in the last post, I have now orphaned the Pagure Debian package. Here’s the full text I posted on the BTS: After several years, I finally decided to orphan pagure :-(. I haven’t been using it as my personal forge anymore, and unfortunately upstream development slowed down quite a bit after the main author and maintainer stopped contributing regularly to the project. But that is not to say that upstream is dead; they are still working towards preparing the next release.

Planning to orphan Pagure on Debian

I have been thinking more and more about orphaning the Pagure Debian package. I don’t have the time to maintain it properly anymore, and I have also lost interest in doing so. What’s Pagure Pagure is a git forge written entirely in Python using pygit2. It was almost entirely developed by one person, Pierre-Yves Chibon. He is (was?) a Red Hat employee and started working on this new git forge almost 10 years ago because the company wanted to develop something in-house for Fedora.

Migrating my repositories to Forgejo

After some thought, I decided to migrate my repositories to Forgejo. I know, I know… The name sucks a little bit, but nothing is perfect. Forgejo is a fork of Gitea, and was created after some drama regarding Gitea Ltd taking over the development of the Gitea project. I have to be honest and say that I’m growing tired of seeing so much drama and confusion arise from Free Software communities and projects, but in a way this is just a reflection of what’s happening with the world in general, and there’s very little I can do about it.

Using WireGuard to host services at home

It’s been a while since I had this idea to leverage the power of WireGuard to self-host stuff at home. Even though I pay for a proper server somewhere in the world, there are some services that I don’t consider critical to put there, or that I consider too critical to host outside my home. It’s only NATural With today’s ISP packages for end users, I find it very annoying the amount of trouble they create when you try to host anything at home.

Ubuntu debuginfod and source code indexing

You might remember that in my last post about the Ubuntu debuginfod service I talked about wanting to extend it and make it index and serve source code from packages. I’m excited to announce that this is now a reality since the Ubuntu Lunar (23.04) release. The feature should work for a lot of packages from the archive, but not all of them. Keep reading to better understand why. The problem While debugging a package in Ubuntu, one of the first steps you need to take is to install its source code.

Novo blog, novos links

Eu sei que não posto aqui há algum tempo, mas gostaria de avisar os meus leitores (hã!?) de que eu troquei a engine do blog pro Hugo. Além disso, vocês vão notar que as URLs dos posts mudaram também (elas não têm mais data, agora são só compostas pelo nome do post; mas veja abaixo), e que também houve uma mudança na tag pt_br: futuramente eu pretendo parar de postar coisas nela, e vou postar somente usando a tag portugues.

New blog, new links

I know I haven’t posted in a while, but I’d like to let my readers (who!?) know that I’ve switched my blog’s engine to Hugo. Along with that change, there are also changes to post URLs (no more dates, only the post name; but see below) and also a change to the en_us tag: eventually, I will stop posting things under it and start posting solely under english. If you’re subscribed to the en_us RSS/ATOM feed, please update it accordingly.

Debuginfod is coming to Ubuntu

These past couple of months I have been working to bring debuginfod to Ubuntu. I thought it would be a good idea to make this post and explain a little bit about what the service is and how I’m planning to deploy it. A quick recap: what’s debuginfod? Here’s a good summary of what debuginfod is: debuginfod is a new-ish project whose purpose is to serve ELF/DWARF/source-code information over HTTP. It is developed under the elfutils umbrella.

I am not on Freenode anymore

This is a quick public announcement to say that I am not on the Freenode IRC network anymore. My nickname (sergiodj), which was more than a decade old, has just been deleted (along with every other nickname and channel in that network) from their database today, 2021-06-14. For your safety, you should assume that everybody you knew at Freenode is not there either, even if you see their nicknames online. Do not trust without verifying.

A debuginfod service for Debian

Hi there. Long time no write! This last Tuesday, February 23, 2021, I made an announcement at debian-devel-announce about a new service that I configured for Debian: a debuginfod server. This post serves two purposed: pay the promise I made to Jonathan Carter that I would write a blog post about the service, and go into a bit more detail about it. What’s debuginfod? From the announcement above: debuginfod is a new-ish project whose purpose is to serve ELF/DWARF/source-code information over HTTP.

Aqueles que se foram

Quando, na calada da noite, nos deitamos para dormir, somos assaltados por um pensamento que começa como uma simples conjectura, mas que logo tranforma-se num martírio sem fim. O que faremos quando voltarmos à rotina? Como aturaremos o olhar que nos fulmina quando nos encaramos no espelho? Aquela pessoa que viveu, viu e partilhou de momentos difíceis de explicar; aquela alma que já não se diz pura tampouco inocente; aquele brilho apagado que não nos mostra caminho algum… Tudo isso, todas essas coisas serão características absolutamente insignificantes perto da imensidão do vazio que estende sobre nós.

Installing Gerrit and Keycloak for GDB

Back in September, we had the GNU Tools Cauldron in the gorgeous city of Montréal (perhaps I should write a post specifically about it…). One of the sessions we had was the GDB BoF, where we discussed, among other things, how to improve our patch review system. I have my own personal opinions about the current review system we use (mailing list-based, in a nutshell), and I haven’t felt very confident to express it during the discussion.

Improve gcore and support dumping ELF headers

Back in 2016, when life was simpler, a Fedora GDB user reported a bug (or a feature request, depending on how you interpret it) saying that GDB’s gcore command did not respect the COREFILTER_ELF_HEADERS flag, which instructs it to dump memory pages containing ELF headers. As you may or may not remember, I have already written about the broader topic of revamping GDB’s internal corefile dump algorithm; it’s an interesting read and I recommend it if you don’t know how Linux (or GDB) decides which mappings to dump to a corefile.

Debian Bug Squashing Party, Toronto version

Heya! This past Saturday, April 27th, 2019, Samuel Vale, Alex Volkov and I organized the Toronto Bug Squashing Party here in the city. I was very happy with the outcome, especially the fact that we had more than 10 people attending, including a bunch of folks that came from Montréal! The start It was a cold day in Toronto, and we met at the Mozilla Toronto office at 9 in the morning.

Don't come here

If you’re brazilian, don’t come here. If you voted for the president-elected, don’t come here. If you think it’s better to have a dead son than a gay son, don’t come here. If you think it’s OK to kill first and ask later (or perhaps don’t even ask), don’t come here. If you would like to say the things he said, don’t come here. If you think he didn’t really mean what he said, don’t come here.

Sem Dúvida

Com essa maré de notícias ruins que tá assolando o mundo, fica difícil saber o que dizer quando tento explicar, pra mim mesmo, o que anda acontecendo no Brasil. Não dá pra entender, não dá pra saber, mas mais do que isso: não dá pra acreditar. Eu poderia falar sobre a burrice generalizada que está brotando nas pessoas, mas aí eu iria soar um pouco presunçoso, e isso não é uma coisa boa, né?

Hello, Planet Debian

Hey, there. This is long overdue: my entry in Planet Debian! I’m creating this post because, until now, I didn’t have a debian tag in my blog! Well, not anymore. Stay tunned!


Back then, I still wanted to write something. Back then, life was different, and I had another view of myself and of others. Back then, my house of cards was still standing, giving the impression that it was safe and sound, that its foundation was solid, and that nothing would shake it. But that was back then. Right now, I have lost my will and my power to concentrate, to focus on what really matters, because what really matters is still undefined.


Às vezes, é preciso combater. É preciso dizer que o outro está errado, que ele está falando besteira sobre um assunto que não conhece (e não quer conhecer). É preciso dizer o que é ético, o que é certo. É preciso discernir tudo o que é errado e anti-ético, imoral, e que faz mal. É preciso combater o ódio, muitas vezes com amor, outras tantas com força e integridade. É preciso falar praquele ignorante que ele não sabe o que é Software Livre.

Memory mappings, core dumps, GDB and Linux

After spending the last weeks struggling with this, I decided to write a blog post. First, what is “this” that you are talking about? The answer is: Linux kernel’s concept of memory mapping. I found it utterly confused, beyond my expectations, and so I believe that a blog post is the write way to (a) preserve and (b) share this knowledge. So, let’s do it! First things first First, I cannot begin this post without a few acknowledgements and “thank you’s”.
