{{OLPC}}
{{Draft}}

The purpose of providing software for connected laptops is to make affordances for desirable human behaviors like

* reading, writing, computing, sharing
* reflecting, creating images and sounds,
* speaking, broadcasting, publishing
* searching, listing, following,
* configuring, modifying, and debugging

Some affordances provided by the OLPC 8.1.1 operating system and most collections of activities include the ability to:

; Connectivity
: associate with 802.11 b/g access points with or without WEP and WPA1 encryption.
: associate with other XO or Active-Antenna 802.11s meshes.

; Localized Text Entry
: keymaps are correct or are very close to correct for US/International, Amharic, Spanish, Portuguese, and Kreyól keyboards.

; Recording Audio and Video
: We've got a camera, a microphone input with optional voltage bias, and some speakers. 
:: Pippy, Record, and TamTam will be able to play and record sounds. 
:: Pippy and Record will be able to take photographs. 
:: Record will be able to record short videos. 
:: Measure will be able to measure signals with or without DC voltage bias.
:: volume keys on the keyboard will adjust the speaker volume while Sugar is running.

; Multi-media Composition
: pictures can be composed with text in a system editor such as Write. (We actually expect [[Write]] to do a lot of other things.)
: fancier multimedia like video, audio, and programs can be manipulated in an environment like [[EToys]].

; Interpreters for Standard Data Formats
: be able to display and edit DOC, ODT, JPEG, PNG, GIF, WAV, OGG, HTML, JS, some SWF, and several other less-well known formats.
: We expect NOT to be able to display [[Restricted Formats|restricted formats]] including MP3, MPEG, most AVI, RM, FLV, etc.

; Extensibility and Malleability of Software
: w/ internet: install new software via 'yum install' or 'rpm -U' via the internet. Data in /home should be PRESERVED.
: w/ internet: olpc-update to new versions of the operating system via the internet. Data in /home should be PRESERVED.
: w/ preparation: olpc-update to new versions of the operating system via USB. Data in /home should be PRESERVED.
: w/ preparation: reflash appropriately signed builds via USB. NO DATA should be preserved.
: access the root account via the virtual terminals or via the Terminal activity (if present.) 
: access to the firmware "ok" prompt w/ developer key, requestable through Browse

; Real-time Synchronous (RS) Collaboration
: ''Reliability of current RS collaboration is conditioned in complicated ways on available network bandwidth, packet loss rates, connectivity scenario, and exact software protocol/implementation. See the [[Collaboration network testbed]] for details.''

; Robustness
: Installing or removing activities should never change the ability of the system to run.
:: ''In practice, bad things may happen if you run out of disk space or if you remove/modify the Journal or Terminal.''
:: ''Alternately, malicious code could circumvent the isolation framework separating activities from system software and user data.''

; Power Conservation
:: when the lids are closed, suspend in order to conserve power.
:: resume from suspend in response to input such as key-presses, mouse motion, power-button presses, unicast network traffic addressed to the laptop, and several other stimuli.

; Peripherals
: store user data to and to retrieve user data from FAT16/VFAT formatted USB Mass Storage devices.
: We DO NOT expect to be able to store user data to or to retrieve user data from SD cards until {{Ticket|6532}} is addressed.
: USB ethernet adapters, keyboards, and mice should function similarly to their normal function on other operating systems.
: login via serial consoles.
: We do not have strong expectations about the behavior of other peripherals.
