== Look and feel ==

The [[user interface]] iswas designed with similar general goals to earlier Palm OS releases, with an aim of preserving the ''Zen of Palm'', a design philosophy thatcentered revolves aroundon making the applications as simple as theypossible.<ref>{{cite canweb|last=|first=|date=June 13, 2003|title=Zen of Palm|url=http://www.accessdevnet.com/docs/zenofpalm/ZenFront.html|url-status=dead|archiveurl=https://web.archive.org/web/20130310232907/http://www.accessdevnet.com/docs/zenofpalm/ZenFront.html|archivedate=March 10, 2013|accessdate=October 20, be2009|website=|publisher=Accessdevnet.com}}</ref> Other aspects of the interface includeincluded a task-based orientation rather than a file/document orientation as is commonly found on desktop systems.

The appearance of the platform<ref>[http://www.mobilelinuxinfo.com/392/access-linux-platform-screenshots/ New Access Linux Platform Screenshots], Mobilelinuxinfo.com, [[August 9]], [[2007]]. {{webarchive |url=https://web.archive.org/web/20110104022347/http://www.mobilelinuxinfo.com/392/access-linux-platform-screenshots/ |date=January 4, 2011 }}</ref> iswas intended to be extremelyhighly customizable to provide differentiation for specific devices and contexts.

In the last releases, they went for a much more modern look with gesture support, and were no longer close to the Palm OS.

== Base frameworks ==

Similarly to [[maemoMaemo]], (Nokia's internet tablet framework), ALP iswas based on components drawn from the [[GNOME]] project, including the [[GTK+]] and [[GStreamer]] frameworks. A variety of other core components arewere drawn from mainstream open source projects, including [[BlueZ]], [[Matchbox (window manager)|matchbox]], [[cramfs]], and others. These components arewere licensed under the [[GPLGNU General Public License]] (GPL), [[LGPLGNU Lesser General Public License]] (LGPL), and other [[open source license]]s, meaning that ALP iswas a "''free"'' or "''open"'' environment on the software level.

A number ofSeveral components from ALP have been themselveswere released under the [[Mozilla Public License]] as The Hiker Project.<ref>[{{cite web|last=|first=|date=|title=Framework aims to commercialize mobile Linux apps|url=http://www.linuxdevices.com/news/NS6832325233.html|url-status=dead|archiveurl=https://web.archive.org/web/20090603003603/http://linuxdevices.com/news/NS6832325233.html|archivedate=June Framework aims to commercialize mobile Linux3, apps]2009|access-date=|website=}}, Linuxdevices.com, [[December 22]], [[2006]].</ref><ref>[http://www.access-company.com/news/press/ACCESS/2007/20061221_hiker.html Access Releases Hiker Application Framework to Open Source Community], [[Access Co.|Access]] [[press release]], [[December 12]], [[2006]]. {{webarchive |url=https://web.archive.org/web/20120205103947/http://www.access-company.com/news/press/ACCESS/2007/20061221_hiker.html |date=February 5, 2012 }}</ref> These components addressaddressed issues of application life-cycle, intertask communication, exchange and use of structured data, security, time and event-based notifications, and other areas common to the development of applications for mobile devices.

== Application development ==

AsThe aALP fairly standard Linux/open source-based system, the Access Linux Platform presentspresented standard APIs for most common operations, (as defined by the POSIXstandards andfor LSBPortable standards).Operating SinceSystem neitherInterface ([[POSIX]]) norand [[Linux Standard Base]] (LSB). addressHowever, areasneither suchstandard asaddresses telephony, device customizationcustomizing, messaging, etc.,or thereseveral areother atopics, numberso ofseveral additionalother frameworks and APIs were defined by Access for these areasthose.

Applications for ALP cancould be developed as Linux-native code in [[C (programming language)|C]] or [[C++]], as legacy [[Palm OS]] applications (which run in the ''Garnet VM'' emulation environment), or in [[Java (programming language)|Java]]. AdditionalFurther execution environments can bewere supported via the development of a "''launchpad"'' utilizedused by the Application Manager (part of the Hiker framework).

The ALP SDK usesused an [[Eclipse (software)|Eclipse]]-based [[integrated development environment]] (IDE), with additionaladded plug-ins, as did its predecessor Palm OS development environment. The compilers used arewere embedded [[EABIapplication binary interface]]- (EABI) enabled [[ARM architecture|ARM]] versions of the standard [[GNU Compiler Collection|gcc]] (GCC) tool chain.

== Security ==

The Access Linux PlatformALP utilizesused a combination of a user-space policy-based security framework and a kernel-space [[LSMLinux Security Modules|Linux security module]] to implement fine-grained access controls. The components for ALP's security implementation have been released as part of the Hiker framework. Controls arewere based on signatures and certificates; unsigned applications can be allowed access to a pre-definedpredefined set of "''safe"'' APIs.
