Google Summer of Code 2015

Introduction

KolibriOS is going to apply as a mentoring organization for Google Summer of Code 2015. This page contains our ideas list and some additional information for students and mentors.

Student Requirements

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. Examples of such tasks can be obtained by asking on developers chat or on our IRC channel (#kolibrios @ irc.freenode.net). 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. This task has to be completed before student application deadline (27 March 19:00 UTC).

In addition, students need to answer the following questions when applying:

1. Full Name (First + Last Name).
2. E-mail address.
3. Nickname you plan to use on our forums, SVN repository or IRC chat.
4. Age.
5. Country + city of residence.
6. Human languages you speak (write all languages and knowledge level - basic/intermediate/expert/mother tongue).
7. Name of college or university you are accepted into or enrolled in + link to their website.
8. Name of program (or faculty, or department) in that college/university you are accepted into or enrolled in.
9. Your current timezone in UTC/GMT terms (for example, Paris is UTC/GMT +1 hours right now).
10. Have you been involved with any open-source project in the past? If yes, which one, and what have you done for that project?
11. Code samples - please provide links to code that you have written. It can be your high school project, contribution to open-source organization, your college/university task or anything like that.
12. The task you are willing to work on from our list of Summer of Code 2015 ideas (or suggest your own idea, if you don't like any of the proposed ideas).
13. What other time commitments, such as school work, another job, planned vacation, etc., will you have between May 19 and August 18?

We have discussed "Google Summer of Code 2015" 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 2015

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.

CPUID application

Summary: Update existing CPUID application to be familiar with new CPUs and their features.

Details:

• Primary goal: Write code to detect and report new CPUs and features.
• Additional goals: Refactor code as to use system libraries (libimg, box_lib, etc).
• Language: Assembler/FASM
• Skill level: beginner/intermediate
• Importance: Low
• Suggested by: dunkaist
• Mentor: dunkaist
• Links: CPUID program, Intel cpuid, AMD cpuid

QR-code in boot log

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

Error creating thumbnail: Unable to save thumbnail to destination

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.
