Nepomuk is not fast, is instant!

Everybody that has been a KDE user for the last 2 years knows Nepomuk and its bad reputation, maybe it was desired in the past, but no more. This morning I decided to get my Nepomuk up and running again, and I have to say that it is impresive! just take a look at
this video:

The only thing I had to do is modify a kernel configuration, but I had to do it because my distributionb (ArchLinux) didn’t for me, others like Ubuntu or OpenSuse have the correct value.

Execute:
sysctl fs.inotify.max_user_watches
fs.inotify.max_user_watches = 524288

If you get a value such 8000 then you have to change it, to do it:

echo “fs.inotify.max_user_watches = 524288″ >> /etc/sysctl.conf

and restart.

The only thing I’m missing now is a good plasmoid (Crystal to the rescue?).

Update: I’m using trunk (4.6), but afaik Nepomuk should be as fast as in 4.5
Dolphin searchbar is a feature found in 4.6 (to be released in 2 months)
If you update the parameter using sysctl command remember to restart nepomuk.

Kamoso is alive!

After months of being almost a dead-zombie project now the Kamoso development has been resumed, we can say that it is in better shape than ever! Motivated by the QtGstreamer project, Aleix and I decided to port Kamoso to it and see how it goes (it has been the perfect excuse to revive the project). So far we didn’t regret the change. Besides the technology switch (we we’re kind of ok with libvlc), the change has given to us new forces to work on the project, let’s see what we’ve got so far:

Current features:
  • Take pictures
  • Upload pictures to facebook (kipi plugins export interface)
  • Record video
  • Upload videos to youtube
  • Burst mode
  • Smoother thumbnails view
  • Fancy overlay icons to indicate what files are being uploaded
Work in progress:
  • Add some logic to decide what microphone to use (depending on platform).
  • Facebook video support
  • Choose webcam
  • Twitpic support
The application is quite stable right now, so we’re open for feedback, to compile it you have to:
1-Have gstreamer installed (base and good plugins are needed)
3-Get Kamoso sources from git.kde.org:kamoso
Well make a release shortly, for the waiting here comes a Kamoso2 funny video:
The video’s recorded in the screencast are uploaded Ereslibre Sexy and Ereslibre Monkey.

Cya and Happy Hacking!

Meego Conference, day 1

As you may guess, I’m in Ireland like a lot of other hackers attending the MeeGo conference. I’ve been here since Saturday and so far I love the city and the people in here, lovely place.
Today (Monday 15) has been the first day of the conference and it has been great, good organization and a good general mood provoked by a mix of “enthusiasm and desire change things”. Maybe the worst part of the day has been discovering how little bit people know about us (KDE), many people know more or less what we are (A Desktop), but nothing solid, even some of them got surprised when I told them that the entire KDE SC is made by using Qt, definitely we’ve room for improvement in spreading our community and our software.
As a final note, today I’ve got a N900 from Nokia (Thanks!), can’t wait to hack on it and try to run Kamoso in there, would be awesome, wouldn’t it?
Time to sleep, cyap!

My KDE’s way (for the next 6 months)

Today, is the last day of my holidays, I could say that it is pity, but it is not, I’m addicted to my work :$


During this relax vacations, I’ve dedicated a part of the time into analize the current situation of KDE, and with that try to find my spot between all the work that needs to be done. Probably during the next days I will publish some blog entries with the cloncusions got, but this entry is about what I’m going to do in KDE in the follow 6 months. I think that having an agenda and try to achieve it is very important to do not get distracted in the way. KDE is a big community with a lot of work to be done, is important to have clear where you want to help, and try


to find the balance between “What have to be done” and “What you want to do”.
One of the best and most impresive facets of KDE, is our implication in a lot of fields, from office applications, to “The cloud”, passing trhough PIM. With all these options, is not trivial to decide where to collaborate, again find the balance between “Where I’m needed” and “Where I want to be”.
Taking into account all of that, this is my conclusion:


Hardware:
One of the most frustrating things when you install KDE in a PC, is not been able to use some kind of hardware, for example: Webcams, Bluetooth,  Printers… This is somethign weird since all mentioned before have an excelent support in GNU/Linux. A lot of this things are more or less supported (printers for example), but they don’t have the elegance we are looking for. Other types of hardware like the finger readers are not supported at all althought there are some work done there. This is my TODO list:


  • Continue the BlueDevil development (Bluetooth)
  • Revive Kamoso (Webcam)
  • XRandR support (Screen management).
  • LibSolid asynchronous API
Zeroconf and friends:
A few weeks ago, I was using empathy when I noticed somebody called “Alfredo Rollan” in my contact list. I started to wonder who was that guy, and what was he doing in my contact list… After a while I remembered Bonjour, so I ran trhough everybody using osx to see if any of them was the so called “Alfredo”, and indeed I found him. That event started my curiosity about Bonjour, Avahi and  Zeroconf. I started to perform the typical searchs: “Avahi KDE” “Zeroconf KDE”… Then I discover our kio network:// and that kopete actually supports Bonjour (but you’ve to create the account yourself). After seeing the potential of this, I think that is very important for us beeing able to support these technologies. Image for example being at akademy and just after you connect your computer to the network you start to see a lot of people in your contact list, everybody wil be able to share the akademy photos just by clicking in one button, and you will be able to reach them just by using your file browser, all of this without configuring anything. I don’t have clear what I want to do in this topic, so before do anything I will:


  • Investigate Avahi, and what KDE supports
  • Investigate UPnP, and what KDE supports
  • Investigate Samba, and what KDE supports
  • Investigate NFS, and what KDE supports
Small things here and there:
Something that is annoying me from the current status of KDE software is that some things are “half working” or at least they are for me, and some other things are lacking the “Elegance” we want to achieve. List of things I want to do:


  • Investigate CUPS and all the “printing” thing.
  • Investigate PulseAudio and KDE Sound system (kmix, phonon)
Documentation:
As some of you may know, where I work we have the fridays free to work on what we want, the idea is to give something back to the community. After much thinking, I belive that the best I can do in that 8hours is improve the documentation in KDE. This is not a final TODO:


  • Understand how doxygen work
  • Take a look at how KDE uses doxygen
  • Take a look at how Qt and other projects does it
  • Understand the current techbase layout
  • Trace a plan.
A lot of things to do, and only 6 months ahead, beter stop talking and start to do some fresh autumn hacking :)
Happy hacking!
