• Desktop, Desktop and Desktop, Sprint in Pineda de Mar (Barcelona)

    First of all, excuse the super late release of this post, I have been super busy up to the point where I couldn't use 15min to spellcheck this post, now I had to adapt it a little bit, change times etc.

    From 11jun to 18jun we had an amazing sprint in a small town near Barcelona called Pineda de Mar. This sprint was organized to gather all the developers highly motivated in move the Desktop forward, including those working in areas not strictly related to what the user sees or not strictly known as part of the desktop. We had a week of fun and work lead (as usual :p) by Kevin Ottens.
    We had endless discussions about our weak and strong spots , hacked a little bit (some more than others), played table tennis (Yay for the Southern European team vs the British Empire), and enjoyed good quality food done mostly by Dario Freddi (let the italians cook we say) though more people worked in the kitched to prepare delicious disesh (Kevin, Sebas, Clemens, Marco Martin, Lluis Eskerda...).

    It is hard to describe what the environment of a sprint is like, just imagine that you are with your best friends a whole week doing what you love only stopping for eating and having fun. In this case KDE is the people and what we love is our software, full week non-distractions equals super productivity of all kinds. It is hard to summarize the whole week, but these are my personal highlights of the sprint:

    • Almost everybody attending the sprint would like shorter and more dynamic releases (à la chrome or kernel).
    • Everybody agrees that we must be careful when modifying the Desktop, we don't want to make it worst !
    • Common agreement that we have to start looking for alternative to the current windows 95 paradigm.
    • Our current notifications suck and we know how to fix'em (1) (2) (3).
    • Virtual desktop are a thing from the past in its current state.
    • Activities are a super awesome concept, yet we are nowhere close to make them appealing in the desktop (as they are in the tablet)
    • Knowledge about Plasma terminology was shared and kind of agreed on (did you know that Plasma Active is about all form factors? yes! that includes the desktop !)
    • We need better PulseAudio support
    • We need a better screen support
    • Lots of stuff to clean and polish! papercut program by Agateau on the way
    • Lot of people using icontask (this is more of a personal note :p)
    • WebAccounts is supermegaultraimportant, we need it now.
    • We want KTp or even better "KPeople" everywhere, it will become one of our new pilars.

    On this list (I hope quite close to the reality) you can see more or less the feeling of the Desktop developers, and especially that it is alive in all senses.

    I hope you could see a glimpse of how intense a sprint is lived and how useful they are.

    Bye !


  • Samba-mounter, quick fix for a larger problem

    There was a time, years ago when computer users only needed to keep all their files in one place, and occasionally make some backup to a CD or DVD. Then the mp3 players appeared and those users had to copy the music from the computer to the player usually via USB, that's all we needed we thought... well we were wrong :)

    The amount of devices we have and we use is increasing and so does the amount of data we manage, some may think that a regular non geek user has few files but if you take a closer look you will see that the average user actually has hundreds of pictures, hundreds of sounds, hundreds of films, dozens of documents... So we have to ask ourselves a question: Can we continue with the model of copying that data around? the answer is no.

    Motivated by that need users are starting to setup a central computer or a device such a NAS with the only propose of  storing data and make it available to any device that may need it such: cell phones, players, ebook readers, tv's, other computers etc. Some times that central place is not even a computer dedicated to do that job but instead the daily used computer, I'm specifically thinking on a laptop.

    The file transfer are usually done with protocols such nfs, webdav, ftp or samba being this last the most common at least in commercial devices. The need for supporting this is clear as users of these systems increase, so how well do we support Samba?

    We have had a kick ass technology called KIO for years, I believe it was developed in KDE 2 and basically it allows to use remote files as if they were local,  meaning that you can use files in an ftp for example without having to use any special programs for it. Even with KIO, we have identify some issues that need to be solved before we can say that our remote file support has no gaps, for example streaming or support for applications not supporting KIO.

    Let's say for example that we have a collection of music in a NAS device and they are shared through Samba, can we reproduce them using any KDE application? or better, can we stream and reproduce them? the answer is sadly no.

    There are a series of technical problems that we have to fix to make KDE software fully capable of streaming music, I won't bother you with technical details just know that actions are being taken to fix this situation and because of KIO we should be able to stream music on applications that use it in no time hopefully in 4.9.0 or 4.9.1.

    What about applications not using KIO, is there any way for making them work ? short answer is it depends.

    There are technical mechanisms for making Samba remote files look like local for all applications, for example for this protocol we have cifs, smbnetfs and fusesmb. According to the tests we performed only cifs is fast enough to provide a good experience but still you usually need to know some command or edit a file you are not supposed to modify in order to have a good experience so it is not a solution by itself.

    We are designing a solution that will make KIO available to any application, but that will take months of developing and testing  and we needed something fast, something to include in Netrunner 4.2 Dryland SE... So we created samba-mounter.

    Samba-mounter is a small piece of code that makes easy the usage of cifs, improving the experience of those who need to access files shared through samba.

    Take a look at the following video:

    You can download the code from here:

    I expect to write a blog post explaining the long-term solution in the following weeks.


  • Akademy-es 2012, makes everything worth it

    Most of you know me because of all the work I do on KDE in form of code: Kamoso, BlueDevil, Solid... It is the stuff I put on my blog so if you know my involvement in KDE because of my blog it is normal.

    Besides writing code, I'm starting to be involved in other areas all across our community, one of them is KDE-España.

    KDE-España is the legal representation of KDE in Spain, you can consider it as a sister of KDE e.V but only for the local community. One of the activities we do is the Akademy-es, a gathering of users and developers that happens every year in a different city of the country, so far we have had: Barcelona, Saragossa, Coruña, Bilbao, Barcelona, Saragossa (again :p) and sure more to come.

    You may think these events are less important than writing software and that I shouldn't waste my time there. I say you are wrong and that at least they are equally important.

    As a personal note, for me it is becoming one of the events I wait the entire year to attend even if it is only to see the group of friends I only see in that conference.

    So I'd like to encourage you to organize Akademy's or smaller events on whatever city/country you live in, building a strong local community is crucial for keeping this global ship alive.

    Can't wit for Akademy-es 2013 :)


  • Joining the Blue

    I planned to announce this when it happened but got stuck with travels and work so it got delayed a bit (2 months :p).

    I'm glad to say that I will be sponsored by Blue Systems to work on various parts of the Workspace, so far we have defined two areas of work:

    • Improve transparent file browsing (KIO) and make it available to all applications.
    • Improve web and online services integration into the Workspace, by adding a single point of configuration.

    In these two months I have been working already on those areas making the first releases that will be included in the  upcoming netrunner version (4.2 Dryland SE). Both releases are designed to be a first stone of a much complete solution on which I will be working on at least  for the following 6 months.

    For those of you who may be wondering, this changes nothing regarding my other KDE implications, I'm going to continue working on BlueDevil (bluetooth) and libsolid and other projects I'm cooking while others sleep :p

    Let's keep rocking !

     


  • One less thing that can put your laptop in danger

    A few months ago it almost happened to me. It was horrible. I was traumatized. I wonder, how can that happend in 2011? why me? why to my laptop?

    It was a worm afternoon in Madrid, the meeting I attended was so intensive I didn't get to login into the KDE Plasma Workspace session but instead I let the laptop on the KDM login page. Once the session finished I closed my laptop and put it in my bag full of battery.

    I'm not sure about the amount of time, but probably between 3 to 4 hours later I arrived home, opened my backpack and there it was, I found my laptop burning, hot as hell I even had to grab a cloth to open the lid and move the laptop to some place cool. From that day my new battery went form 98% of capacity to 90.

    That night, I  sent an email to some KDE mailist asking for this issue, until today nothing has been done to fix it.

    I don't want anybody to pass from the same I went through, that's why now with lightdm-kde the computer will suspend if the lid is closed.

    Next thing I want to do is show the battery remaining somewhere and suspend the computer after 2 minutes of idle time.

    With that, lightdm-kde will have great power management support.
