Mageia Blog (English) : Time time time, see what’s become of me?

As you may or may not know, we are scheduled to release the first beta for Mageia 5 on September 30th. Well… it looks like we’re not going to make it.

Here at Mageia HQ, we try to provide a balance between tried-and-tested software and cutting edge developments. That means that we try to ship Mageia releases with the newest software that we are comfortable using. We take into account all sorts of things, from stability to security and passing through usability on the way.

The practical upshot is that we are planning to release Mageia 5 with the new version of RPM 4.12. RPM is Mageia’s package manager, that we share with other major distros such as Fedora and OpenSuSE. This new version brings in a lot of interesting features, so we decided to include it in Mageia as soon as it was released, so that we can fine tune our usage of it before Mageia 5′s release. The new version was included just before the mass rebuild, an important phase of the release cycle where we rebuild all packages of Mageia 5 to make sure they compile properly against the new development stack.

Technobabble aside, the RPM version update is a good thing. It makes it easier for the packagers to find common errors and fix them, thus allowing for more reliability of our packages. That means that more time can be devoted to adding more packages for you, the user.

The problem is, well… the new RPM version broke some stuff. Not much, just a few packages needed to be rebuilt. Something like 7000 packages (now down to about 2000).
But have no fear! Our development and packagers teams are on it! They just need a little more time. So we are postponing the Mageia 5 Beta 1 release by two weeks. That means October 14th.

Let’s recap: we try to make the best Linux distribution that we can, and sometimes things don’t go according to plan. But we are flexible enough to handle it! So if you were counting down the days to Mageia 5 Beta 1, just move your clock back by 14 days.

And, as always, we welcome volunteers. So if you want to help, have a look here and start contributing today!



Liberdade na Fronteira : Month of KDE Contributor: From LaKademy …

26 de Setembro de 2014, por Desconhecido - 0sem comentários ainda

In recent weeks I had an intense “Month of KDE Contributor” that began with LaKademy, the KDE Latin American Summit, and ended with Akademy, the KDE World Summit. It was a month somewhat tiring, hard work, but it was also filled with good stories, great meetings, new contacts, discoveries and, I can say, fun.

This post I will write about LaKademy and the next I will comment about Akademy.

The second edition of LaKademy took place in São Paulo, one of the biggest cities of Latin America, in FLOSS Competence Center of University of Sao Paulo, an entire building dedicated to studies and researches on various aspects of free software: licenses, software engineering, metrics extracted from repositories, social aspects of collaboration, and more.

This year I and Aracele were the conference organizers, and I believe that we could provide all the infrastructure necessary to LaKademy attendees had good days of work in a pleasant and comfortable places.

First day we had talks of collaborators, and one that most caught my attention was Rafael Gomes on KDE sysadmin. It’s amazing the size of the infrastructure behind the scenes, a solid base that allows developers to do their jobs. It would be interesting to promote more this type of collaboration to attract potential contributors who prefer this side of computing.

This day I presented a talk about Qt in Android, describing the development tools configuration in Linux, presenting a basic Hello World, and commenting on some softwares availables using this technology, specially the VoltAir and GCompris. The presentation is below (in portuguese).

.

Second day we had a short-course about Qt, presented by Sandro Andrade. Impressive his didactic and how he manages to hold our attention for a whole day without getting boring or tiring. This day I was helping the other participants, especially those who were having the first contact with Qt development.

The third and fourth days were devoted to application hacking and projects development. I joined in “task-force” to port Bovo to KF5, I started the development of a metapackage to install all KF5 packages in Mageia, and I started the port of Cantor to KF5. I also fixed some KDE Brazil bots on social networks.

Task force to port Bovo to KF5

Fourth day we had a meeting to discuss some initiatives to promote KDE in Latin America, and we started to use Kanboard of KDE TODO to organize the implementation of these projects.

Besides the work we had some moments of relaxation at the event, as when we went to Garoa Hacker Clube, the main hackerspace in São Paulo, an activity we call Konvescote; and also when we all went to Augusta Street, one of the famous bohemian streets in the city.

KDE + Garoa

However, as in all events of Free Software and KDE Brazil, the best thing is see old friends again and meet new ones that are coming to the boat. For the novices, welcome and let’s to do a great work! For the veterans, we still have a good road ahead on this idea of writing free software and give back to the world something of beautiful, high quality technical, that respect the user.

KDE Brazil team wrote an excelent post enumerating what the attendees produced during the event. I suggest to all who still want more information to read that text.

I leave my thanks to KDE e.V. for providing this meeting. I hope to see more contributors in next LaKademy!



Liberdade na Fronteira : Month of KDE Contributor: …to Akademy

26 de Setembro de 2014, por Desconhecido - 0sem comentários ainda

In recent weeks I had an intense “Month of KDE Contributor” that began with LaKademy, the KDE Latin American Summit, and ended with Akademy, the KDE World Summit. It was a month somewhat tiring, hard work, but it was also filled with good stories, great meetings, new contacts, discoveries and, I can say, fun.

Previous post I wrote about LaKademy and now I will write about Akademy.

LaKademy had ended just one day before and there I was getting a bus to São Paulo again, preparing for a trip that would take about 35 hours to Brno, with an unusual connection in Dubai and a bus from Prague, the Czech Republic capital, to the city of the event.

Arriving at Brno my attention was piqued by the beautiful architecture of this old city of the Eastern Europe, something exotic for Brazilians. During the event I had some time to walking in the city, especially on some nights for dinner and during the Day Trip. I could calmly enjoy the details of several buildings, museums, the castle and the city cathedral.

It was the second Akademy I attended, if you count the Desktop Summit in 2011. This time I am a member of the KDE e.V., the organization behind KDE, so my first task was to attend to General Assembly.

I was fascinated how dozens of contributors from different parts of the world, from different cultures, were there discussing the future of KDE, planning important steps for the project, checking the accounts of the entity, in short, doing a typical task of any association. I was also impressed by the long applause for Cornelius Schumacher, a member of the KDE e.V. Board since 2002 and former president of the association. A way to show gratitude for all work he accomplished in those over 10 years in KDE e.V. Board.

In the end the day we had a reception for participants at Red Hat. I was impressed with the size of the company in the city (three large buildings). We drank some beers of the country and distribute Brazilian cachaça. =)

IMG_20140905_193708

The next day began the talk days. I highlight the keynote of Sascha (I believe he was invited to Akademy after Kévin Ottens have seen him lecture here in Brazil during FISL), and the talk on GCompris, software that I admire because it is a educational suite for children. Unfortunately, one of the lectures that I wanted to see not occurred, that was Cofunding KDE aplications. We were David Faure talking about software ports to KF5, and presentation of KDE groups of India and Taiwan in the end of day.

The second day of talks we had a curious keynote of Cornelius who presented some history of KDE using images of old contributors. The highlights of the day were also the presentations by VDG staff, the group that is doing a amazing design work in Plasma 5, and now they are extending their mouse pointer to KDE applications too. Great!

Another interesting presentation was on Next Generation of Desktop Applications, by Alex Fiestas. He argued that the new generation of software need to combine information from different web sources in order to provide a unique user experience. He used examples of such applications, and I’m very curious to try Jungle, video player that will have these characteristics.

Finally this day had a lecture by Paul Adams, very exciting. He shows that, after investigation in KDE repositories, the degree of contribution among developers decreased with the migration from SVN to GIT, the number of commits decreased too, and more. Paul has interesting work in this area, but for my part I think it is necessary to explain this conclusions using anothers concepts too, because we need to understand if this decreased is necessarily a bad thing. Maybe today are we developers more specialized than before? Maybe is the decrement of commits just a result of code base stabilization in that time? Something not yet concluded in KDE is that we came from a large unified project (including in repository level) to a large community of subprojects (today we are like Apache, maybe). In this scenario, is it worth doing comparisons between what we are today with what we were yesterday, based only on our repositories? Anyway, it is a good point to ponder.

In BoFs days, I participated in the first two parts of the software documentation  BoF – an important and necessary work, and we developers need to give a little more attention to it -; FOSS in Taiwan and KDE Edu in India. Unfortunately I could not attend to packagers BoF (well, I am a packager in Mageia), because it occurred in the same time of Taiwan BoF. Letś try again in next Akademy. =)

I like to see the experiences of users/developers groups in other countries; the management of these activities attracts me, mainly because we can apply either in Brazil. I left this Akademy with the desire to prepare something about Latin America community to the next event. I believe we have much to share with the community about what we’re doing here, our successes and failures, and the contribution of Latin American for the project.

Finally the other days I continued working on the Cantor port to KF5 or I was talking with different developers in the halls of university.

To me it’s very important to participate in Akademy because there I can see the power of free software and its contributors, and how this culture of collaboration brings together different people for development and evolution of free computer programs. Therefore, I would like to thank immensely to KDE e.V. for the opportunity to go to Akademy and I would like to say that I feel very good to be part of this great community that is KDE. =)

The best of all is to see old friends again and meet new people. When that e-mail address gets contours of human face is a very special moment for us who work “so close and so distant”. So it was amazing to be with all of you!

And to finnish I desire a great job to the new KDE e.V. Board!

Those interested, most of the talks presented with video and slides are available in this link.



Olav Vitters : Systemd in GNOME 3.14 and beyond

7 de Setembro de 2014, por Desconhecido - 0sem comentários ainda

Plan to get rid of ConsoleKit in GNOME 3.14

Before the start of the GNOME 3.14 cycle, Ryan Lorty announced his intention to make most GNOME modules depend on a logind-like API. The API would just implement the bits that are actually used. According to Ryan, most GNOME modules only use a selection of the logind functionality. He wanted to document exactly what we depend on and provide a minimal API. Then we could write a minimal stub implementation for e.g. FreeBSD as we’d know exactly what parts of the API we actually need. The stub would still be minimal; allow GNOME to run, but that’s it.

Not done for GNOME 3.14. Needs urgent help.

As didn’t see the changes being made, I asked Ryan about it during GUADEC. He mentioned he underestimated the complexity in doing this. Further, his interests changed. Result: still have support for ConsoleKit in 3.14, though functionality wise the experience without logind (and similar) is probably getting worse and worse.

Systemd user sessions

In future I see systemd user sessions more or less replacing gnome-session. The most recent discussions on desktop-devel-list indicated something like gnome-session would still stay around, but as those discussions are quite a while ago, this might have changed. We’re doing this as systemd in concept does what gnome-session does anyway, but then better. Further, we could theoretically have one implementation across desktop environments. I see this as the next generation of the various XDG specifications.

Coming across as forcing vs “legacy”

From what I understood, KDE will also make use of user sessions, logind, etc. However, they seem to do this by calling the existing software “legacy” and putting everything into something with a new name. Then eventually things will be broken of course. Within GNOME we often try to make things really clear for everyone. E.g. by using wording usch as “fallback”. It makes clear our focus is elsewhere and what likely will happen. I guess KDE is more positive. It might still work, provided
someone spends the effort to make it work. In any case, the messaging done by KDE seems to be very good. I don’t see any backlash, though mostly similar things is occurring between GNOME and KDE. There are a few exceptions, e.g. KWin maintainer explicitly tries to make the logind dependency as avoidable as possible. I find the KDE situation pretty confusing though; it feels uncoordinated.

Appearance that things work fine “as-is”

In a lot of distributions there is still a lot of hacks to make Display Managers, Window Managers and Desktop Environments work with the various specifications and software written loads of years ago. Various software still does not understand XDG sessions. They also do NOT handle ConsoleKit. Distributions add hacks to make this work, doing the ConsoleKit handling in a wrapper.

This is then often used in discussions around logind and similar software.

“My DM/WM/DE is simple and just works. There is no problem needing to be solved.”

There are various distributions which have as goal to make everything work, no regressions are allowed. If you use such a distribution and given enough manpower, enough hacks will be added which on short term ensures things work. However, those temporary hacks are hacks. E.g. if some software should support XDG sessions and it does not, eventually the problem is with that software.

Looking at various distributions, I see that those temporary hacks are still in place. Especially funny one is Mageia, where XDG session support is second class. The XDG session files are generated from different configuration files. This results in fun times when a XDG session file changes. Each time this happened, the blame is quickly with the upstream software. “Why are they changing their session files, it should just never change”. While the actual problem is that the upstream files are thrown away!

The support for unmaintained software has at various points resulted in preventable bugs in maintained software. While at the same time the maintained software is considered faulty. I find this tendency to blame utterly ridiculous.

Aggressive anti-advocacy

There are many people who have some sort of dislike for systemd. In the QA session Linus had at Debconf, he mentioned he appreciates systemd, but the does NOT like the bughandling. In various other forums I see people really liking systemd, but still having their doubts about the scope of systemd.

When either liking or disliking systemd, it is important to express the reason clearly and in a non-agressive way. Unfortunately there are a
few people who limit their dislike in ways that’ll result in them being ignored completely. Examples are:

  • Failure to understand that a blank “you cannot rely on it” statement is not helpful

    If a project sees functionality within systemd that is useful, it is you’ll not get very far with stating that the project is bad for having used that. Or suggesting that there is some conspiracy going on, or that the project maintainer is an idiot. That’s unfortunately often the type of “anti-systemd advocacy” which I see.

  • Failure to provide any realistic alternatives

    Suggesting that systemd-shim is an alternative for logind. It’s a fork and it took 6 months or so to be aligned. Further, it’s a fork with as purpose to stay compatible. It’s headed by Ubuntu (Canonical) who are going to use systemd anyway.
    The suggestions are often so strange that I have real difficulty summarizing them.

  • Continuous repeat of non-issues

    E.g. focussing on journald. Disliking e.g. udev or dbus, confusing the personal dislike as a reason everyone should not use systemd.

  • Outright false statements

    E.g. stuff “systemd is made only for desktops”, “all server admins hate it”. If you believe this to be true, suggest to do your homework. That, or staying out of discussions.

  • Suggesting doom and gloom

    According to some of the anti-advocacy, there’s a lot of really bad things in systemd. A few examples: my machine should continuously corrupt the journal files, my machine often doesn’t boot up, etc. As it’s not the case, it pretty much destroys any credibility I’d have for people making these claims.

    Anyone trying systemd for the first time will also notice that it’ll just work. Consorting to this type of anti advocacy will just backfire because although systemd is NOT perfect, it does work just fine.

  • Lack of understanding that systemd is providing things which are wanted

    Projects have depended on systemd because it does things which are useful. As a person you might not need it. The other one beliefs he does need the functionality. Saying “I don’t” is not communication. At least ask why the other believes the functionality is useful!

  • Lack of understanding that systemd is focussed to adding additional wanted functionality

    Systemd often adds new functionality. A large part of that functionality might have been available before in a different way. It’s something which most people seem to worry about. It’s usually added as a response to some demand/need. Having a project listen to everyones needs is awesome!

  • Personal insults

    This I find interesting. The insults are not just limited to e.g. Lennart, the insults are to anyone who switched to systemd. A strategy to of having people use something other than systemd by insulting them is a very bad strategy to have. Especially if you lack any credibility with the very people you need and are insulting.

  • Failure to properly articulate the dislikes

    There are too many blank statements which apparently has to be taken as truths. Saying that something is just bad (udev, dbus, etc) will be ignored if the other person doesn’t see it as a problem. “That systemd uses this greatly used component is one of the reasons not to use it”. Such a statement is not logical.

  • The huge issues aren’t

    Binary logging by journald. Anti-advocacy turns this into one of the biggest problems. The immediate answer by anyone is going to be that you can still have syslog and log it as you do now. If you advocated this as a huge issue, then anyone trying to decide on systemd will quickly see that this huge issue is not an issue at all.
    The attempt is to make people not use systemd. In practice, if the huge issues aren’t an issue, then the anti advocacy is actually helpful to the adoption. The biggest so called problems are easy, so anyone quickly gains confidence in systemd. Not what was intended!

  • Outright trolling

    For this I usually just troll back :-P

What I suggest to anyone disliking systemd is to not make entire lists of easily dismissed arguments. Keep it simple (one is enough IMO), understandable but also in line with the people you’re talking to. Understand whom you’re talking to. Anything technical can often be sorted out or fixed, suggest not to focus on that.

Once the reason against is clearly explained, focus upon what can be done to change things. Here the focus should be on gaining trust and give an idea on what can be done (in a positive way).

Don’t ignore people who dislike systemd

Due to having seen the same arguments for at least 100 times, it’s easy to quickly start ignoring anyone who doesn’t like systemd. I’ve noticed someone saying on Google+ that the systemd should not be used because Lennart is a brat. Eventually enough is enough and it is time to tell these people to STFU. But that’s not according to one part of the GNOME Code of Conduct, “assume people mean well”. Not believing in people meaning well and ignoring it has bitten me various times.

Turns out, this person is concerned that his autofs mounted home directories won’t be supported some time in the future. So this person does follow what Lennart writes. While it appeared to me he’s just someone repeating the anti-advocacy bit, he has a valid concern. I still think it is unacceptable to call people names and said so, but it
is equally important to ensure things are still possible.

Can a “not supported” still be made to work?

Systemd developers are quick to point out that something is not supported. E.g. a kernel other than Linux. A libc other than glibc. Some use cases are not. But there’s a important thing to know: would the usecase be impossible, or would it take way more effort?

The type of effort is also important. For a different kernel/libc, you’d need a developer with good insight into these things. For others, it might be possible by customizing things. I assume the autofs homedirs will always be possible, just not always taken into account.

If it is not supported, but can be used anyway if you’re an “ok” sysadmin, that’ll mean for most people it’ll be possible. A “not supported by systemd” does therefore not 1 on 1 relate to impossible. If you want a different libc but you’re are a sysadmin and not a developer that’s quickly seen as impossible. While another “not supported” is actually perfectly possible.

IMO it is good that not everything is supported. Ensure that whatever is supported works really well. But at the same time, I think more focus should be on ensuring people do understand that a “not supported” does not mean “cannot work”.

My opinion on systemd as a release team member

I like *BSD. I like avoiding unneeded differences, this easies portability.

There are some interesting tidbits I’ve learned. Apparently OpenBSD is a GSoC student working on providing alternative implementations for hostnamed, timedated, localed and logind. I don’t think it’s enough, because it needs to be maintained fully. I further think that a logind alternative cannot be written together with the other bits just during a summer. Whatever it is, I think this will make it even easier to use systemd, not really what some of the anti-advocacy is intending, but oh well.

There seems to be another round of (temporary) increase of people disliking systemd. I’m pretty sure it’ll quiet down to normal levels again once Debian has systemd in a stable release for a few months.

Eventually they’ll notice that although systemd is not perfect, it just works. Unfortunately, this all doesn’t help in with the concerns I still have.

What to do with ConsoleKit?



Mageia Blog (English) : Summer has come and passed…

29 de Agosto de 2014, por Desconhecido - 0sem comentários ainda

…the lazy will never last.

September 19th! That’s the last day when we will accept artwork submissions!

We’re looking for a new default background that will be shipped with Mageia 5. We might also pick one or two runners up that will be bundled as alternative backgrounds. Ideas for screensavers and other artwork that you think we could use will also be appreciated.

Please make sure that you read and understand the rules.
You can submit your artwork to the Flickr page or send it by email to artwork@group.mageia.org.

If you want to win the background contest, here’s a few points to keep in mind:

  • Historically speaking, the images chosen for the default background were simple abstract artworks that used the Mageia color palette.
  • Photos of real life objects/people/plants/animals will not even be considered.
  • Your image must be an original piece, and you must be able to provide source files (xcf or svg). If you can’t comply for a technical reason, please get in touch with us on the Atelier mailing list.
  • Your image must have a sufficient resolution.
