|||
* 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; |

* [http://www.google.com Google Docs] (spreadsheet and word processor) work flawlessly from the XO browser. In addition, they are also shareable applications. |
|||
* [http://www.apple.com/webapps/ Apple Web Apps], although designed for the iPhone, work well for the XO. You access them from your Browser. In many cases just zoom into the page to fill the screen. |
|||

|||
===Games=== |
|||
* Numerous [[Activities#Games|games]], including variations of the “memory game”, strategy games, etc. |
|||
===Shared Applications=== |
|||
All applications share a common data store accessible through the Journal. |
|||
Several applications, including reading, writing, recording and browsing, allow for child-to-child and teacher-to-child [[collaboration]] to varying extents through the network. See [[Activity sharing]] and [[Collaboration Tutorial]]. |
|||
===Running other Linux apps=== |
|||
You can install and run many other Linux applications by using yum or rpm from the console or Terminal activity. By way of example, see the [[Skype]] page in the wiki. |
|||
==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. |
|||
== School Server == |
|||
The [[School server]] is software for a resource-rich peer to the laptop, which provides additional storage, and Internet access. |
|||
* [[XS Server Software]] |
|||
* [[XS Installing Software]] |
|||
== Additional [[Software projects]] == |
|||
(Please see the [[Activities]] page for a more complete list of activities being developed for the laptop. Below is just a sampling.) |
|||
* [[Measure_/_Oscilloscope]] |
|||

|||
==Builds, images, and schedules== |
|||
OLPC regularly compiles and assembles "builds" of the OLPC software listed here for development. |
|||
This process creates software updates for the XO Machines, |
|||
and [[OS images|OS "images"]] of the bundled software that users on other computers can run by [[Emulating the XO]]. |
|||
These builds progress towards various official releases of the OLPC software: |
|||
* See [http://xs-dev.laptop.org/~cscott/olpc/streams/ Builds] for a list of build targets for manufacturing, in-the-field updates, and future software development; |
|||
* See [http://dev.laptop.org/roadmap Roadmap] for the high-level schedule of releases. |
