|||
[[Software]] has some general discussion. |
|||
==Operating system== |
|||
* Linux Kernel: Linux 2.6.22; [http://fedoraproject.org/ Fedora] 7 base environment. |
|||
** The OLPC specific bits of the kernel are pulled from the olpc-2.6 GIT tree on dev.laptop.org: (http://dev.laptop.org/git?p=olpc-2.6) |
|||
==Programming environment== |
|||
* [[Python]] (Version 2.5); |
|||
* [[JavaScript]]™; |
|||
* [[Csound]], music programming language; |
|||
* The [[Etoys]] implementation of [[Squeak]] using Smalltalk, an object-based programming language; |
|||
** Please see [[Sugar Etoys]] for a detailed description of the Sugar implementation |
|||
* [[Turtle Art]], a graphical programming environment; |
|||
* Gnash, a free and open source plug-in for the Adobe Flash™ file format supporting vector and raster graphics, a scripting language called ActionScript™ and streaming of audio and video; |
|||
* Adobe's Flash Player and Java™ virtual machine can be added via Yum or RPM install but are not part of the standard distribution. |
|||
===Libraries=== |
|||
* Mozilla [http://www.mozilla.org/newlayout/ Gecko]/[[Xulrunner]] (the Firefox web engine); |
|||
* GUI toolkit ([http://www.gtk.org/ GTK+]) ([http://www.gnome.org Gnome]); |
|||
* [http://projects.o-hand.com/matchbox Matchbox] window manager; |
|||
* [http://www.pango.org/ Pango] text layout; |
|||
* Gnome accessibility toolkit ([http://developer.gnome.org/projects/gap/ ATK]); |
|||
* Python [[GTK for OLPC | GTK]]+ bindings version 2.10; |
|||
* [http://cairographics.org/ Cairo] 2D-graphics support; |
|||
* [http://x.org X Window System] X.org Foundation; |
|||
* Font rendering ([http://www.freetype.org/ Freetype]); |
|||
* [http://telepathy.freedesktop.org/ Telepathy] real-time communications framework; |
|||
* [http://avahi.org/ Avahi] local service discovery; |
|||
* Multimedia framework: [[GStreamer]] and [http://www.helixcommunity.org RealNetworks]; |
|||
* [[Bitfrost]] security system; |
|||
* Mesh network; |
|||
* Game library: [[Pygame]] |
|||
Libraries to support all of the above, others can be installed by Yum or RPM. |
|||
===User environment=== |
|||
* [[Sugar]] graphical user interface, written in Python, on top of the X Window System and the Matchbox Window Manager. |
|||
** “Zooming” interface to mesh network; |
|||
** [[Journal]] interface to file system; |
|||
Flash space available for other software content ~800 MiB. |
|||
==Applications== |
|||
There are three types of activities distributed with the base system: tools for exploring, expressing, and collaborating. A matrix of applications that have been (or are being) built for the laptop can be found [[Activities|here]]. |
|||
===Tools for exploring=== |
|||
* a [[Browse|web browser]] built on the [[xulrunner | Firefox engine]]; |
|||
* a simple [[Read|document viewer]] based upon [http://www.gnome.org/projects/evince/ evince] (including the ability to view PDF); |
|||
* [[News Reader]], an RSS (“really simple syndication”) reader ([http://penguintv.sourceforge.net/ PenguinTV]); |
|||
* multimedia playback using gstreamer (the Real Networks Helix™ platform has been ported to the laptop and is available for download but is not part of the base distribution); |
|||
* OpenDocument Viewer to read documents in OpenDocument format, a highly-compressed format that is a fully open international standard (ISO 26300); |
|||
* The [[Opera]] web browser and the Real Networks [[Helix media activity|Helix™]] platform have been ported to the laptop and are available for download but not part of the standard distribution. |
|||
* [[Measure]], a tool for exploring the physical world by measuring DC and AC voltages, observing them on a oscilloscope-like interface, being able to watch waveforms in frequency domain (spectrum analyzer), logging data at a specified time interval, and drawing the graph of logged data. |
|||
===Tools for expressing=== |
|||
* [[TamTam]], a music synthesis and composition tool; |
|||
* Etoys (see above); |
|||
* a [[Write|word processor]] based upon the [[Abiword]] project; |
|||
* [[Record]] video, audio, and still-image capture and playback (a “video wiki” is under development); |
|||
* [[Draw]], a pixel-paint programming; |
|||
* a [[OLPC_Human_Interface_Guidelines#Journaling|journal]]; |
|||
* [[MikMik]], a wiki with WYSIWYG editing, using [[Crossmark]] (under development); |
|||
* [http://www.vim.org VIM] and NANO text editors. |
|||
===Tools for communicating=== |
|||
* [[Chat]] and serverless instant messenger; |
|||
* [[Video Chat]] (under development); |
|||
* a VoIP client (under development); |
|||
* Email through the web-based Gmail service; |
|||
* Native email client (under development). |
|||
===Other Tools=== |
|||
* Calculator; |
|||
* Spreadsheet (under development); |
|||
* a shell and debugger; |
|||
* [[Develop]], an activity editor (under development); |
|||
* [http://foss.sit.rp.sg/main Remote Desktop], a tool to remotely control XO laptop; |
|||
===Games=== |
|||
* Numerous games, including variations of the “memory game”, strategy games, etc. |
|||
See the games list on the activities download page [[Activities#Games]] |
|||
===Shared Applications=== |
|||
All applications share a common data store accessible through the Journal; |
|||
Most applications, including reading, writing, recording and browsing, allow for collaboration; through the network: child-to-child and teacher-to-child. See [[Activity Sharing]] and [[Shared Sugar Activities]] and [[Tubes Tutorial]]. |
|||
==Mesh Networking== |
|||
* The specifications for the wireless networking interface include: |
|||
* Ability to act as a mesh point when laptop's main CPU is off; |
|||
* Support for asymmetric links/paths; |
|||
* Incremental releases—mesh networking is available immediately on XO; Upgrades will continue to improve functionality and adherence with standards; |
|||
* Simultaneously acts as a mesh point and an infrastructure node. |
|||
* Standards Compliance: follow 802.11s draft when possible. |
|||
== Additional [[Software projects]] == |
|||
* [[Measure_/_Oscilloscope]] |
|||
* [[OLPCities]], a virtual world programming environment |
|||
* [[FACIL]], a webpage editor developed to be used by children. (In English at http://wiki.laptop.org/go/EASE) |
|||
* [[Musical Editor]], a music composition toolkit |
|||
* [[Drawing Workshop]], a shared graphics space |
|||
* [[Tux Paint]], a paint program with extreme ease-of-use |
|||
* [[BlockParty]], a Tetris-like game that exploits the mesh |
|||
* chat, serverless linux instant messenger http://retroshare.sf.net , VOIP, email |
|||
* a shell and debugger |
|||
* [[Develop]], an activity editor |
