So. Recently I blogged about Network status aware apps, and some time later, I got asked by a developer How do I see if I m online if I m not using network manager? and I replied with some dbus commands and he shook his head in despair. So, I ended up writing a small plasma widget targetting developers and very powerusers that can tell you the current state of the network and offers to add yet another manual datapoint to the network status. So. In line with another blog post of mine about getting the small utilities we all write and just let stay in a drawer (or somewhere in ~ on a local computer), I m announcing it s existance. That application became famous and even mentioned in Linux Weekly News, but I don t expect that here. But anyways, here it is: http://quickgit.kde.org/?p=scratch/sune/networkstatus.git. And a picture of it, it is not pretty but well, it s a tool mostly for developers, not for end users. Have fun, and I hope to see more of these small projects from various people.

Many of us out there writes small tools to just solve a simple task that you need. Here, I will present a tool I needed last night. I have a small job doing a wordpress site for some people, and I needed a image with the site title in a font matching some specific criteria (like a double story lowercase A and a small serif on lowercase L, while in general being a Sans Serif type). So what I needed was a application that let me write a word or a phrase, and see it written with all available fonts on the system. So, it took a little more than a effective hour and 120 lines of code to come up with this: Click to see image And if anyone cares, I have pushed the sources to git.kde.org. I m sure many of you also have various such small apps. Let s see them. That s also you Eike and your svgtoy app :) Another thing I learned from this app is that the ukij fonts targetted the Uyghyr language actually is very interesting also for western europeans.

I have mentioned it before in some blog posts that I m out looking for a job. In my job searching process, there is a couple of nice tools that I am missing. Maybe if I describe one of them, someone will say that it already exists over there -> or something. Tool 1. Tracking of data related to a job application.
For each such application I send I have a set of data, some pieces only for some applications:

• Contact data for company
• The open position I m applying for on the web
• The web form I submitted a application thru
• The email I used to submit my application
• Further emailing with the company
• Further chat logs (jabber or irc) with the company
• My jotting down during or after a (phone) interview
• Other data I ve gathered about the company

I would like one simple way of browsing all this information for a given position. Does this exist? preferably something that can interact with Konqueror, KMail, KAddressbook, KJots, Kopete and irssi on a remote machine. Tool 2: Tracking of tasks with states There is at least the following steps in a job searching process:

• Interesting company found
• Initial contact
• More information sent
• Phone interview
• First interview
• Second interview
• First draft contract
• Signed contract

A job application might go thru some or all of these steps or even more steps, and from each step it can end prematurely with a rejection . Here, I m missing a tool to track my applications and in which state they are currently in. My first thought here is a bug tracking system, but I m wondering if there is something nicer. Currently I m tracking it manually in a KJots notebook. Comments are open. And no, I haven t yet found a job.

Am I online or not? There is a summary at the end for the quick readers. It is in many modern applications important to be able to more or less gracefully handle if the application user is online or not. For example, there is no need to try to fetch emails if the device (computer, phone, tablet, laptop, ) doesn t have network (wifi, cable, umts, ip over avian carriers, ..). KDE has of course made nice functionality for this, and here I will try to describe how to make your app network status aware and what to be aware of in the process. Solid background All this is going on in Solid, using two parts of Solid and a bit of KDE s infrastructure:

• libsolid
• networkstatus KDED module

The networkstatus KDED module is trying it best to gather information from the computer to see if one is connected or not. It has the possibility to gather information from various sources, and handle changes and such. The as of writing available sources that the networkstatus module gathers information from is

• Network Manager
• wicd
• asking the linux kernel thru the abstraction layers ntrack and libnl
• connman might be work in progress

Collecting from different sources is important, because some people might have configurations like Manage wireless thru wicd , manage umts dongle with Network Manager and manage wired network with /etc/network/interfaces and all of it needs to be combined. Solid reports, if wicd thinks online , and network manager thinks offline that the user is Connected.. Solid States There is a enum with 5 values in Solid to describe the current state of the network:

enum Status
Unknown,
Unconnected,
Disconnecting,
Connecting,
Connected
;
Connected is the easy state. Here, Solid knows that you are having some kind of connection according to at least one of the sources. But it might just be a local network connection, and not actually a internet connection. So one here should handle connection failures gracefully. Unconnected is a similar easy state. Here, Solid knows that you don t have any internet connection according to the sources it knows about. One should here not try to do any networking. Connecting and Disconnecting is that a state change is happening, so that you can prepare to react on it. Solid also has the state of Unknown, used for cases where Solid doesn t have the required data to actually know it. A example could be a system without any of the data providers. You should here probably try to connect, and be able to handle failures gracefully. Also described as Proceed with caution . The bright reader might here notice that one both in the Unknown and Connected case actually should do the same. Querying for network status At any given time:

Solid::Networking::Status currentStatus = Solid::Networking::status();
if(currentStatus==Connected currentStatus==Unknown)
//try to do networking things
else
//mark application as offline.

Here, we first query Solid for current status, and then if the state is Connected OR Unknown, then we proceed. Getting notified Maybe you don t want the roundtrip of asking (resulting in a dbus rountrip each time) when you need to know the state changes. Then you of course can get notified. class MyNetworkAwareClass : public QObject
Q_OBJECT
public:
MyNetworkAwareClass();
void doNetworkActivity();
private Q_SLOTS:
void networkStatusChanged(Solid::Networking::Status newstatus);
private:
Solid::Networking::Status m_current_state
; MyNetworkAwareClass::MyNetworkAwareClass : m_current_state(Solid::Networking::Status())
connect(Solid::Networking::notifier(), SIGNAL(statusChanged(Solid::Networking::Status),this,SLOT(networkStatusChanged(Solid::Networking::Status)));

void MyNetworkAwareClass::networkStatusChanged(Solid::Networking::Status newstate)
m_current_state = newstate;
void MyNetworkAwareClass::doNetworkActivity()
if(m_current_state == Unknown m_current_state == Connected)
//try to do network activity


I guess this should be pretty self explaining. Summary

• Ask Solid::Networking::status() for network status
• Connect to statusChanged(Solid::Networking::Status) from Solid::Networking::Notifier to be aware of changes
• Treat the states Unknown and Connected the same way.

Oh. And I m out looking for a job.

John Layt recently blogged about his adventure with having children use Plasma Active with quite some success. The task I was this evening out at a board meeting in my local scout group, and for such a event you of course need the following

• Agenda
• Treasures report
• Minutes from last meeting
• Various other papers

I ve heard from various people that an iPad is great for such meetings, and produces much less paper waste, so of course, I wanted to try with my brand new Plasma Active tablet. Before meeting So before meeting: Charge tablet & fetch needed documents.
Possible issues: Everything was on a my imap server. Minutes was a plain text file, Agenda was a docx file, treasures report was a xls spreadsheet, and the various other papers were pdf files. For fetching, I ve heard a lot about Kontact Touch and everything using Akonadi. Besides me not being fully able to properly enter my password in the first 10 tries, and a sometimes flaky internet connection, everything here was a breeze. To the three first documents, the answer was Calligra Mobile . Rendered even the docx file better than libreoffice did. And Calligra Mobile was nice and touch friendly and worked pretty well for this. There is also something called Calligra Active , which is supposed to be way cooler, but still misses at least one essential feature to be used for a touchscreen only. It can only open documents passed to it on command line. And I m not yet very comfortable with a onscreen keyboard. For the last, there was Okular. The desktop edition of Okular. I was impressed by *how* usable Okular were for a touch screen device. A quick and dirty edition of a mobile Okular could probably be done with remove all toolbars and menubars and such and if no file is passed on command line, then open a file selector window and open selected file , which shouldn t take a person knowing the Okular code much time. But that s still just the Quick and dirty edition During And during the meeting, everything worked flawlessly, except the internet on site, so I was happy I had prepared in advance. As a extra bonus, Plasma Active offered the nice KDE Games, as John Layt also mentioned, for the parts of the meeting where it was a bit boring. So. At least for me and in this case, Plasma Active did its job, at least to a A. And it is still described as Alpha software. Issues There is, though, a few important usability issues: For QWidget based applications, oxygen s nice desktop feature of being able to move the application by dragging it from almost everywhere is just completely useless on a touch screen device when you are only using full screen applications. Luckily, oxygen-settings can disable this. Update: People tells me that this has already been fixed. The Network Manager Plasma Widget, in case of no network , is very hard to activate in order to select a network. A bit larger touch area here would be very nice. Currently, it feels like it is only slightly larger than a dot: . Future Oh boy, I m looking forward for Plasma Active getting to Beta or RC status. Or Final! And btw, I m looking for a job.

It s been a while since I last blogged, and some things has happened. Jobs
I m out looking for a job. Preferably KDE/Qt or Debian related. Or at least opensource related. Feel free to contact me if you know of anything. sune AT vuorela DOT dk Desktop Summit I ve been at Desktop Summit, awesome as usual to see all these great people, except monday morning. I think intel is partly to blame here :-).

• I got to a set of exciting talks, including one about a toaster.
• I got to meet some nice people, both old and new
• I hacked a bit on libprison
• I walked along the Berlin Wall, sat and enjoyed Brandenburger Tor and other parts of Berlin
• Learned to feel home in Berlin public transportation

Prison and such
The upcoming release of Prison will at least have a couple of new features, beside a couple of bugfixes:

• It is now possible to set the colors to be used for the barcodes. That s going to be nice in some cases.
• I have a patch in my mailbox adding EAN13-support from a brand new contributor. It just needs a bit of polishing and then ready to go

I ve also started to enjoy -Werror=unused-but-set-variable in GCC and killed some of those in KDE land. end There is more to come later, hopefully things about the ExoPC I gotborrowed at Desktop Summit, which is now running Plasma Active & Contour. Things about a new librison release, and maybe more places to use libprison. Oh. And yes, I m out looking for a job.

I ve gotten a couple of complaints on the amount of daemons that is launched by default by any app built upon the KDE Frameworks, so I investigated one of them a bit. The knotify daemon currently seems to do two things:

1. Keeping some dependencies out of KDE Framework libraries
2. Recieve messages from dbus, parse them, encode differently and send them on to other places over dbus

In the past, the knotify daemon was also responsible of showing popup-messages. So, I did a quick experiment here in Switzerland to try kill off that daemon and merged the code from the daemon into the KNotification part of kdeui. As a proof of concept it works, and if I can cut out some of the newly introduced dependencies it can end up being really nice. There is much less need for a separate daemon these days where knotify doesn t actually paint the popups itself, but rather passes them on to a galago-spec implementing part of the workspace (on linux) or to growl for various non-free platforms.

and it starts with f While looking at the future of the KDE Platform Frameworks here in Randa, Switzerland, a lot of interesting things has been found in kdelibs and kdepimlibs

• KSortableList
• KTypeList
• KAscii

that no one knew what was there for. On the good side, there is also lots of cool stuff, that of course most people knows about and uses

• A real nice job based api
• Nice library for figuring out when there is holidays and special dates in different countries
• IMAP library
• Compression library
• Hardware access library

And a lot of great larger solutions for solving different real life problems

• Akonadi
• KIO
• KParts

And lots of other cool stuff

• I really like the KDE plugin framework
• KIO slaves are great
• Kontact master is great
• Aaron is wearing pink
• Plasma Active seems cool
• The chefs are making good food, even though sometimes lacking a bit of meat

And we have currently nice things in the required runtime components for every app built using kdelibs

• Finger KIO slave
• Floppy KIO slave
• Weird cornercase user tools, some of them broken

Long time no blogging. Earlier, I wrote a blog post about transporting data to mobile phones. I have since then extracted the Data Matrix code I wrote there into a separate library, prison and added support for QR Code as well. So from KDE s next feature release, versioned 4.7 arriving around first of august, you have DataMatrix and QRCode support in Klipper. While on a barcode spree, I also added barcode support to the KDE Addressbooks for easy transfer of contacts. Also using libprison. Also available from 4.7 onwards. Few minutes ago, libprison 1.0 was tagged and hopefully soon, the KDE Sysadmins will publish my tarball. And about the weather. Some nice people wrote Debian Weather which in simple ways shows if it is unsafe to upgrade. Quite recently there have been thunderstorms and heavy rain in Debian Unstable. Perl rain.
I have recently added support for Debian Weather in the Plasma Dataengine for weather. Also available from 4.7 onwards. Last but not least, after spending a couple of hours on trying to understand Q3PtrList and how it was used in KHelpCenter, it is now, as the last component in KDE-Runtime, free of Qt3Support. All for now. Next up. Platform_11

I have been packaging for Debian for a few years now. My first serious package was Wt back in 2007, but I had been backporting for Ubuntu for at least 2 years already, which means I have been doing .deb packaging for about 5 years (!). Last week I decided it was about time stop nagging my sponsors (Vincent Bernat, Thomas Girard and Sune Vuorela) every time I wanted to update the packages I maintain (witty, ace and libmsn), and I finally started the Debian New Maintainer process. The main reason I had not applied for Debian Maintainer yet was it requires some bureaucracy and, well, I d rather spend my time coding or packaging than doing paperwork I sent my Declaration of Intent and soon after, Thomas and Vincent replied and supported my application with very very nice and kind words. Thank you, guys! I m flattered! Had I known I would be buttered up so much, I would have certainly applied a long time ago! But you know what is the best part of this? It shows how open source projects take advantage of all the tools and communications channels we have (IRC, mailing lists, sprints, conferences, etc), and make distributed development work very well: here we have a 900-developers project in which two French guys are praising an Spanish guy they have never, ever met face-to-face (only e-mail, occasional IRC, and the most important of all: code review). Meritocracy at its full extent. Have you ever seen that in a traditional 100,000 workers company with hundreds of developers working in a single project?

Hello fellow developers, The summer is over but I m happy to announce that this year s Summer of Code at Debian has been better than ever! This is indeed the 4th time we had the privilege of participating in the Google Summer of Code and each year has been a little different. This year, 8 of our 10 students succeeded in our (very strict!) final evaluations, but we have reasons to believe that they will translate into more long-term developers than ever, all thank to you. The highlight this year has been getting almost all of our students at DebConf10. Thanks again this year to generous Travel Grants from the Google Open Source Team, we managed to fly in 7 of our students (up from 3!). You certainly saw them, presenting during DebianDay, hacking on the grass of Columbia, hacking^Wcheering our Debian Project Leader throwing the inaugural pitch of a professional baseball game or hacking^Wsun-tanning on the tr s kitsch Coney Island beach. Before I give the keyboard to our Students, I d like to tell you that it will be the pleasure and honor of Obey Arthur Liu (yours truly, as Administrator) and Bastian Venthur (as Mentor) to represent Debian at the Summer of Code 2010 Mentors Summit on 23-24 October 2010, at the Google Headquarters in Mountain View. Like last year, we expect many other DDs to be present under other hats. We will be having 2 days of unconference on GSoC and free software related topics. We all look forward to reporting from California on Planet and soc-coordination@l.a.d.o! All of our students had a wonderful experience, even if they couldn t come to DebConf, that is best shared in their own voice, so without further ado, our successful projects: Multi-Arch support in APT by David Kalnischkies, mentored by Michael Vogt apt-get install MultiArch does mostly work now as most code is already merged in squeeze, but if not complain about us at deity@l.d.o! Still, a lot left on the todo list not only in APT so let us all add MultiArch again to the Release Goals and work hard on squeezing it into wheezy. Debbugs Bug Reporting and Manipulation API by David Wendt Jr., mentored by Bastian Venthur Hello, I m David Wendt, and I went to Debconf10 to learn more about the development side of Debian. Having used it since the 9th grade, I ve been intimately familiar with many of Debian s internals. However, I wanted to see the developers and other Debian users. At DebConf, I was able to see a variety of talks from Debian and Ubuntu developers. I also got to meet with my mentor as well as the maintainer of Debbugs. Content-aware Config Files Upgrading by Krzysztof Tyszecki, mentored by Dominique Dumont Config::Model is now capable of manipulating files using shorter and easier to write models. Thanks to that, packagers may start experiment with creating upgrade models. Further work is needed to support more complicated config files Dominique Dumont is working on DEP-5 parser, I ll shortly start working on a cupsd config file parser.
The best thing about DebConf10 is that every person I talked with knew what I was doing. I had a mission to get some feedback on my project. Everybody liked the idea of making upgrades less cumbersome. On the other side, it was my first visit to United States, so I decided to go on a daytrip on my own (instead of staying inside the building, despite heat warnings). I had a chance to visit many interesting places like Ground Zero, the UN headquarters, Grand Central Terminal, Times square and Rockefeller Center that was a great experience. Hurd port and de-Linux-ization of Debian-Installer by J r mie Koenig, mentored by Samuel Thibault Debconf10 was great! Among other people working on the installer, I met Aur lien Jarno from the Debian/kFreeBSD team and we worked together on a cross-platform busybox package. Besides, the talks were very interesting and I ve filled my TODO-list for the year.
For instance I learned about the Jigsaw project of OpenJDK, and how Debian would be the ideal platform to experiment with it. More generally, some people think Debian could push Java 7 forward and I d like to see this happen. Smart Upload Server for FTP Master by Petr Jasek, mentored by Joerg Jaspert I must say that it was great time for me in NY, I ve met and talked and coded with people from ftp-master team like Torsten Werner who helped me to push the project a bit further and with some other people who were looking forward to release of the tool which I hope they will use quite soon. Everybody interested, everybody excited, really cool place and time. And I can t forget the Coney Island beach and stuff, lot of fun, lot of sun;) Aptitude Qt by Piotr Galiszewski, mentored by Sune Vuorela Currently, development branches support full features searching, viewing extended package s informations, performing cache and packages operations. Code and GUI still require a lot of work which will be continued. Informations about further progress could be found on aptitude mailing list and repository rss channel. Debian-Installer on Neo FreeRunner and Handheld Devices by Thibaut Girka, mentored by Gaudenz Steinlin For me, DebConf 10 started at the airport, where Sylvestre Ledru (whom I didn t know of before) was wearing a GSoC 2007 t-shirt, that is, given the circumstances, almost equivalent to say I m a hacker, I m going to DebConf 10 .
I ve spent my time at the conference attending various talks, hacking, meeting DDs and other hackers (amongst others, my co-mentor Per Andersson, Paul Wise, Julien Cristau, Christian Perrier, Cyril Brulebois, Martin Michlmayr, Colin Watson and Otavio Salvadores who I have to thank for his patience while dealing with my questions), chatting, cross-signing keys, rushing to finish eating before 7pm, getting sunburnt, sightseeing (thanks, Arthur, for the lightning-fast tour of Manhattan!), and so on. Debian Developers and community, we count on you. See you next year! (cross-posted to debian-devel-announce@l.d.o and soc-coordination@l.a.d.o)

3 interesting small things happened in the weekend. Due to the hard work of mostly Florian Reinhard and George Kiagiadakis, Bluedevil is now available. Bluedevil is a new and improved bluetooth handling thing targetted the KDE Workspaces. The Debconf people have uploaded the Qt Debconf frontend that I blogged about a while ago, so now it should be available. Last, but not least, applications now has more accurate data for if they are online or not, by using the ntrack library. This was especially problematic for people having some interfaces defined in /etc/network/interfaces, and other interfaces managed by NetworkManager.
This feature will be committed to upstream KDE whenever Will gets around to do it. As a added bonus, KDEBindings in Debian has seen a release critical bugfix (python plugins, e.g. plasma widgets, related), and the brokenness of Konsole (libkpty) on the kFreeBSD-arches have been tracked down to a libc issue and a patch has been made. All of this is expected to be part of next stable Debian release, codename Squeeze.

I guess we all have the challenge of how to easily get a link or a phone number or some other strings of data from the computer to the mobile phone. With the help of mobile barcodes and klipper, this is now possible in KDE Trunk to do easily. Place some data in clipboard, click on klipper and select Show barcode. To read it, open the barcode app in your phone (mBarcode on n900 for example) and point it to your monitor.

I wrote another blog post a while back talking about Debconf kde frontend. I spend some days at akademy looking at it, and then refined it a bit when I got home.
Results:

• perlqt is in unstable and soon in testing.
• debconf kde frontend works.
• object oriented perl is weird

hopefully, the debconf people will accept it soon.

Hello Planet Debian readers!

I've never thought that such a thing can ever happen, but I've started blogging ;) So now it is time to introduce myself.

My name is Piotr Galiszewski and I am second year student of computer science at AGH - University of Science and Technology in Krakow (Poland). I have been GNU/Linux user for about 5 years (mostly Debian based distributions).

Thanks for Debian and Google, this summer I will be working on creating Qt-based user interface for aptitude as my Google Summer of Code project. I hope that my mentors Sune Vuorela and Daniel Barrows will be patient with me ;) I am sure I will learn a lot from them. Please look at abstract of my project made by Debian GSoC administrator Obey Arthur Liu:

Qt GUI for aptitude. Currently, KDE users need to use Aptitude via the console interface, or install the newly developed GTK frontend, which does not fit well into KDE desktop. Making Qt frontend to Aptitude would solve this problem and bring an advanced and fully Debian-compliant graphical package manager to KDE.

As I wrote in my proposal I will split my work into three main parts:

1. writing low level classes which will abstract aptitude signals and slots (which uses sigc++) into Qt slots and signals.
2. creating and evaluating GUI mockups
3. implementing GUI on top of classes from the first point

Point 1 and 2 will be made simultaneously and will take all May and half of June. Low level classes should implement all necessary functions for further use in GUI. This classes allow me to avoid direct usage of none Qt code in GUI classes and also give much more time to prepare completed and usability-wise mockups. Every mockups version will be presented and discussed on this blog. First version should be ready in next few days and updates will appear each week (or to weeks).
After finishing this two steps I will start coding GUI. With mockups and finished low level classes this should not be complicated (Yeah, I know that this is only my dream).

Full text of my proposal (including more precise time-line) can be found at Debian wiki.

Currently, project is slightly behind the schedule . It is caused by changes in my studies plan. The Juwanalia students' festival took place earlier, and yesterday it finished. But my first exam will take place one week later on 18 May, so I will have more time to catch up with time-line.

This project is my first direct contribution to Debian, but not first involvement in free software movement. I've been Kadu Instant Messenger developer for more then two year. In last two years I have been second most active developer with more than 700 commits in master branch. During GSoC period my Kadu activities will be limited. If time allows me to do this, I will be still contributing to Kadu. I still can be found at Kadu forum or #kadu channel on irc.freenode.net. I will also continue reviewing patches and fixing low time-consuming bugs.

My plans for the next few days:

• continue researching aptitude codebase
• discover all functionalities that should be implemented by Qt frontend
• review of other graphical package manager GUIs (and probably write about my thoughts on this blog)
• create first draft of my mockups

If you have any thoughts about this project, please add comment to this post or contact me directly. I will be glad to read all yours opinions

Cheers

PS. As you can see English is not my mother tongue, so please forgive me my mistakes

I wrote a bit ago a blog post about what debian kde is missing of distribution specific things Some of the more important things includes:

• A Qt based debian installer
• Tools to manage 3rd party modules and firmware and such
• Debconf frontend that fits in
• Report bug interface

Installer
I don t think it is the most important thing. Wether or not the graphical installer is using gtk or qt is not that important. I would love to see it happen, but it is not something I feel like putting my time in. Others are most welcome.
It will give the advantage of giving the installer the possibility to use the framebuffer directly. Modules and firmwares and such
Someone is saying that ubuntu has something called jockey that does this exact thing, with a KDE and a Gnome frontend. Unfortunately, it is python, so it is something I will really avoid. I m hoping that me mentioning it here will make someone into python&debian pick it up and bring it to debian.
It is apparantly some nice magic around discover-data. Debconf frontend that fits
A lot of work has been put into proper perl-qt bindings and they will hopefully be ready for kde4.5, which is unfortunately a series too late for Squeeze :/. But when that has happened, we just need some perl guy to adapt the old frontend to debconf. Reportbug interface
There is already a tool called reportbug-ng that is a qt interface to reporting bugs. All in all, it looks like we are quite far already. We just need to get the last bits put together. Someone: pickup jockey. And note that the comment field isn t a place to report bugs. They will be removed.

So. I was wondering, which nice distro specific tools do exist in debian/gnome or in $other/kde that debian/kde is missing? We have kalternatives for managing alternatives, we have a update notifier frontend in progress and after google summer of code, hopefully a package management frontend, aptitude-qt. (Made by Piotr). But what other distribution specific tools are we missing for Debian-KDE ?

I d like to extend a warm welcome to our selected students for the 2010 Debian Google Summer of Code! They should pop up on Debian Planet soon and you re welcome to come talk to them on #debian-soc on irc.debian.org Aptitude Qt by Piotr Galiszewski, mentored by Sune Vuorela Qt GUI for aptitude. Currently, KDE users need to use Aptitude via the console interface, or install the newly developed GTK frontend, which does not fit well into KDE desktop. Making Qt frontend to Aptitude would solve this problem and bring an advanced and fully Debian-compliant graphical package manager to KDE. Content-aware Config Files Upgrading by Krzysztof Tyszecki, mentored by Dominique Dumont When a package deliver configuration files, the problem of merging user data with new configuration instructions will arise during package upgrades on users systems. Sometimes merging can be done with 3 way merge, but this process does not insure that the resulting file is correct or even legal. This project intends to create standards, tools an heuristics to make the scary config file conflict resolution debconf prompt a thing of the past. Debbugs Bug Reporting and Manipulation API by David Wendt Jr., mentored by Bastian Venthur Currently debbugs supports a SOAP interface for querying Debian s Bug Tracking System. Unfortunately this operation is read-only. This project would create an API for debbugs which supports sending and manipulating bug reports, without having to resort to email. This project does not intend to replace email as mean to manipulate the BTS but rather to enhance the BTS to allow other means of bug creation and manipulation. Debian High Performance Computing on Clouds by Dominique Belhachemi, mentored by Steffen Moeller The project paves a way to combine the demands in high performance computing with the dynamics of compute clouds with Debian. Combining the Eucalyptus cloud computing infrastructure with the TORQUE resource manager and preparing the components for dynamically added and removed instances provides the user with a attractive high performance computing environment. Such a system allows users to share resources with large compute centers with minimal changes in their workflow and scripts. Debian-Installer on Neo FreeRunner and Handheld Devices by Thibaut Girka, mentored by Gaudenz Steinlin This project aims to improve the installation experience of Debian on handheld devices by replacing ad-hoc install scripts by a full-blown and adapted Debian-Installer. The Neo FreeRunner is used as it is the most convenient and open device from a development standpoint, but other devices will also be explored. Hurd port and de-Linux-ization of Debian-Installer by J r mie Koenig, mentored by Samuel Thibault The primary means of distributing the Hurd is through Debian GNU/Hurd. However, the installation CDs presently use an ancient, non-native installer. The goal of this project is to port the missing parts of Debian-Installer to Hurd. To achieve this, all problematic Linux-specific code in Debian-Installer will be replaced by less or non-kernel dependent code, paving the way for better support of other non-Linux ports of Debian. Multi-Arch support in APT by David Kalnischkies, mentored by Michael Vogt Hardware like 64bit processors are perfectly able to execute 32bit opcode but until now this potentiality is disregard as the infrastructure tools like dpkg and APT are not able to install and/or solve dependencies across multiple architectures. The project therefore focuses on enabling APT to work out good solutions in a MultiArch aware environments without the need of hacky and partly working biarch packages currently in use. Package Repository Analysis and Migration Automation by Ricardo O Donell, mentored by Neil Williams Emdebian uses a filter to select packages from the main Debian repositories that are considered useful to embedded devices, excluding the majority of packages. The results of processing the filter are automated but maintaining the filter list is manual. This project seeks to automate certain elements of the filtering process to cope with specific conditions. This project will also generalize to more elaborate and intelligent algorithms to improve the transitions of the main Debian archives. Smart Upload Server for FTP Master by Petr Jasek, mentored by Joerg Jaspert Making packages upload smarter, more interactive and painless for uploaders by switching from anonymous FTP and Cron jobs to a robust protocol and modern package checking and processing daemon. This daemon would test early and report early, saving developers time. More details coming soon on http://wiki.debian.org/gsoc Congratulations everyone and have a fruitful summer!
