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!

The GNU Radical

A friend of mine, Blaise, once told me not to introduce myself as “... what you would call a radical...”. He had listened to me talking to a person who were questioning what a Free Software activist does. My friend's rationale, to which I totally agree, is that you must let the other person decide whether she thinks you are a “radical” or not. In other words, if you say you are a “radical” from the beginning, it will probably induce the other person to a pre-judgement about you, which is not good for you and for her.

As I said, I agree with him. But I am going through a lot of situations in my life that are constantly reminding me that, maybe, I am that “radical” after all. I do not know whether this is good or bad, and I can say I have been questioning myself for a while now. This post, by the way, is going to be a lot about self-questioning.

Respectful Software

To what extent should Free Software respect its users?

The question, strange as it may sound, is not only valid but also becoming more and more important these days. If you think that the four freedoms are enough to guarantee that the Free Software will respect the user, you are probably being oversimplistic. The four freedoms are essential, but they are not sufficient. You need more. I need more. And this is why I think the Free Software movement should have been called the Respectful Software movement.

Fedora on an Acer C720P Chromebook

Yes, you are reading correctly: I decided to buy a freacking Chromebook. I really needed a lightweight notebook with me for my daily hackings while waiting for my subway station, and this one seemed to be the best option available when comparing models and prices. To be fair, and before you throw me rocks, I visited the LibreBoot X60's website for some time, because I was strongly considering buying one (even considering its weight); however, they did not have it in stock, and I did not want to wait anymore, so...

Anyway, as one might expect, configuring GNU/Linux on notebooks is becoming harder as time goes by, either because the infamous Secure Boot (anti-)feature, or because they come with more and more devices that demand proprietary crap to be loaded. But fortunately, it is still possible to overcome most of those problems and still get a GNU/Linux distro running.

Encrypting your e-mails to yourself using GnuPG

It has been a while since I dream of being able to send encrypted e-mail to everyone in my contact list. It is still a distant future, but fortunately it is getting closer with campaigns like the Reset the Net. And while I already send encrypted messages to a couple of friends, it is always good to discover (and share!) some configuration tips to make your life easy :-).

Being Permissive, the new Popular

This post is massively inspired by a post in the gnu-prog-discuss mailing list. This is a closed list of the GNU Project, and only GNU maintainers and contributors can join, so I cannot put a link to the original message (by Mike Gerwitz), but this topic is being discussed over and over again at many places, so you will not have trouble finding similar opinions. I am also “responding” to a recent discussion that I had with Luiz Izidoro, which is a “friend” (as he himself likes to say) of the LibrePlanet São Paulo group.

Privacy as a Collective Good

It has been a while since I wanted to write about this subject. At many presentations that I gave during these last 2 years, I used the expression in the title in order to try to raise more awareness about why we should take care of our privacy (and maybe everyone's). But what does it really mean?

Migrating from Jabberd2 to Prosody

After trying (and failing!) to find a guide, how-to, or anything that could help me in the migration from Jabberd2 to Prosody on my personal server, I decided to write my own version here. I hope it can help other people who want to do this somewhat painful procedure!

Narcissistic behavior

People talk about themselves all the time. Directly or indirectly, they usually have the intention to promote their views, opinions, or increase their self-esteem. I'm wondering now if I'm too radical when I say that I do bother about this behavior...

About coherence, Twitter, and the Free Software Foundation

The Free Software Foundation has a Twitter account. Surprised? So am I, in a negative way, of course. And I will explain why on this post.

You may not agree with me on everything I write here, and I am honestly expecting some opposition, but I would like to make it crystal clear that my purpose is to raise awareness for the most important "feature" an organization should have: coherence.
