Introduction

KolibriOS is proud to be selected as a Mentoring Organization for Google Summer of Code 2014. This page contains our ideas list and some additional information for students and mentors. We are accepting student applications starting March 10th. Prospective students are required to register on our developers forum, join the developers chat and submit a small bugfix / improvement to our SVN in order for their application to be considered. This requirement is only to show us that you are able to work with our SVN and interact with our developers if you are selected.

Last year, we have run an independent Summer of Code using money we collected with Kickstarter. Two students have worked on KolibriOS, and the results of 2013 Summer of Code were: adding write support for EXT2 filesystem, and adding (read-only) support for XFS filesystem.

Organization

You can find the organizers on the IRC channel (#kolibrios @ irc.freenode.net) or at our forum: http://board.kolibrios.org/

Name Nickname Role
Yogev Ezra yogev_ezra Organization Administrator
Jeffrey Amelynck hidnplayr Mentor, Backup Administrator
Ivan Baravy dunkaist Mentor
Sergey Sakhno punk_joker Mentor

We have discussed "Google Summer of Code 2014" application with all active members of the KolibriOS Project Team, and selected only those 3 (three) people who have both the knowledge, the dedication, and the time to help their students during the entire summer. Each one of them was assigned to mentor projects in his area of specialization only. In a rare event when a Mentor from the above list cannot continue mentoring his student(s) due to personal circumstances, we will try to find a replacement Mentor, or ask the remaining Mentors to cover for the missing one. Additionally, there is always a number of knowledgeable members of our team hanging around our forum chat, and they will gladly answer any student questions that may arise, even if they haven't volunteered as Mentors themselves.

Ideas for Google Summer of Code 2014

The below list contains ideas suggested by KolibriOS team members. It is neither complete nor final.
Students are welcome (and even encouraged) to suggest their own ideas for GSoC, provided they can find a mentor amongst KolibriOS developers to guide them.

QR-code in boot log

Summary: Add a QR-code (containing the debug log) at the end of boot process

QR-code.png

Details:

  • Description: Sometimes KolibriOS cannot boot on a certain hardware configuration (gets stuck during or after boot process). In such cases, we request the user having this problem to enable debug log at boot time, take a photo of the screen and show it to us (in the forum). However, sometimes taking a good quality photo can be quite challenging (bad camera, shaking hands etc.) and the attached photo is so blurry to the point the debug log cannot be even read. The idea suggested hereby is to simultaneously encode the debug log which is outputted on the screen, to the form of QR-code, and show the resulting QR-code on empty space on the screen. In such way, any user possessing a smartphone with a camera and QR-code scanner, could scan the QR-code and submit the encoded text directly on our forums (without having a need to take a photo), and our developers, in turn, would get the debug log text immediately and won't have to unscramble a blurry photo.
  • Language: Assembler/FASM
  • Skill level: beginner/intermediate
  • Suggested by: People on habrahabr.ru
  • Mentor: dunkaist

Torrent client

Summary: Write a (bit-)torrent client for KolibriOS

Details:

  • Primary goal: Implement a torrent client similar to µTorrent Free edition
  • Language: Assembler/FASM
  • Skill level: intermediate/advanced
  • Suggested by: People on IRC
  • Mentor: hidnplayr

Filesystem support

Summary: Improve filesystem support in KolibriOS

Details:

  • Primary goal: Add Read-only support for the UDF filesystem.
  • Additional goal #1: Add Write support for the UDF filesystem
  • Additional goal #2: Add Write support for the NTFS filesystem (read-only support already exists)
  • Language: Assembler/FASM
  • Skill level: intermediate/advanced
  • Suggested by: dunkaist
  • Mentor: dunkaist

FTP client

Summary: Create a GUI based FTP client or add FTP support to one of the existing file managers

Details:

  • Primary goal: FTP access (download/upload/etc.)
  • Additional goal: Create an FTP client library.
  • Language: Assembler/FASM
  • Skill level: beginner/intermediate
  • Suggested by: hidnplayr
  • Mentor: hidnplayr

Improve Ethernet support

Summary: Write more Ethernet drivers.

Details:

  • Primary goal: Support for popular Broadcom, Atheros and/or Marvell Yukon cards. (pick 2)
  • Additional goals: Any Ethernet cards students and their mentors find.
  • Language: Assembler/FASM
  • Skill level: intermediate/advanced
  • Suggested by: hidnplayr
  • Mentor: hidnplayr

Music player

Summary: Improve the current music player in Kolibri.

Details:

  • Primary goal: Rewrite the current music player (ac97snd), in FASM, and improve its functionality.
* Support for file formats wav, mp3 and xm (using available external libraries).
* Support for playlists (m3u).
* A time display.
  • Additional goals:
* Use of system wide hotkeys to control player
* Support for metadata (ID3, ...)
* More codecs (flac, vorbis, ...)
* Audio indication (oscillograph, bar graph, ...)
* Show cover art from files or album folder
* Fade in/out and/or crossover
* Streaming radio (at least mp3 over http stream)
* Skins
* Media library
  • Language: Assembler/FASM (C/C++ to port codec)
  • Skill level: intermediate/advanced
  • Suggested by: hidnplayr
  • Mentors: hidnplayr / dunkaist

Web browser: Netsurf

Summary: Complete porting of NetSurf browser for KolibriOS

Links:

Details: Our developer SoUrcerer started working on NetSurf browser port. Since he has no spare time, someone else needs to complete it.

  • Goal: Bring NetSurf browser port in KolibriOS to the point of 90-95% functionality, with all critical and major bugs fixed, and only minor or trivial bugs left. First job would be fixing/enhancing the build system.
  • Language: C (may require writing a few lines in FASM assembly though, to port some libraries)
  • Skill level: intermediate/advanced
  • Suggested by: Pretty much everyone in Kolibri
  • Mentors: punk_joker / hidnplayr

Web browser: HTMLv

Summary: Improve existing text-only web browser HTMLv - add more functionality and compatibility.

Links:

Details:

  • Primary goal: Have mostly complete HTML4 support on a good enough level to read non-complex (mobile?) websites
  • Secondary goal: Add certain elements of CSS, speed optimizations
  • Language: Sphinx C--. May require writing a few lines in FASM though.
  • Skill level: intermediate/advanced
  • Suggested by: Leency / hidnplayr
  • Mentors: punk_joker / hidnplayr
