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.

=== Applications ===

These are userspace tasks. They often require only basic knowledge of algorithms and data structures.<br>

No specific experience is required but welcome.

==== XDXF dictionary ====

'''Summary:''' Write dictionary application with support of XDXF (XML Dictionary eXchange Format)

~~=== QR-code in boot log ===~~

~~'''Summary:''' Add a [http://en.wikipedia.org/wiki/QR_code QR-code] (containing the debug log) at the end of boot process~~

~~[[File~~:~~QR-code.png]]~~

==== FTP client ====

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

'''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 [http://wiki.kolibrios.org/wiki/File:QR-code.png 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.
