From BUG Wiki
The CPU architecture in the BUG. Many PDAs and phones use ARM CPUs. The BUG uses the Freescale i.MX31 ARM-based processor.
The LCD on the BUGbase unit, commonly referred to as the Statusbar LCD. This LCD is used to see status information such as battery status as well as any special information provided by modules and applications. Additionally, a menu system allows users to manage BUGmodules, web services, applications, and System information and tasks (such as shutdown, recalibration of the LCD module, and reset app manager).
Also known as BUGbase, this is the core building block of BUG.
BUG Module Interface: the four connectors on the BUGbase unit that connect to BUGmodules. The BMI connector acts as a hot-pluggable bus in Linux similar to USB. The pinouts from the BMI connector map to common generally available interfaces such as USB, GPIO, and I2C.
A bootloader is the first software that runs on a computer. On a desktop PC this is normally referred to as a BIOS. The BUG originally shipped with Redboot bootloader but has since moved to Uboot to load the Linux operating system.
Application created in Dragonfly SDK. Application can be transferred for execution to BUG. It can also be transferred to BUGnet so it can be shared with the community.
The BUGbase is the foundation of your BUG device, you can think of it as the "brains" of your gadget. More info within the products section of our website.
Each BUGmodule represents a functional component of a BUG device. A BUGmodule could be a digital camera, a GPS receiver, a keyboard, a bar code reader, etc. More info within the products section of our website.
BUGnet is our online community, including the repository for sharing applications.
A bundle is an OSGi term for an application or component. It is a discreet software component. The BUG application layer is a set of OSGi bundles.
An R3 OSGi implementation used in the BUG.
Upon unregistering a bundle from the OSGi Framework all configuration data that might have been set to define its state is gone. To relieve user of pains of reconfiguring the bundle once its active, Configuration Admin can be used to persist configuration data so that upon the bundle's being active again its states can be set to those when they were before bundle was unregistered.
Eclipse is an open-source software framework written primarily in Java. In its default form it is an Integrated Development Environment (IDE) for Java developers, consisting of the Java Development Tools (JDT) and the Eclipse Compiler for Java (ECJ). Users can extend its capabilities by installing plug-ins written for the Eclipse software framework, such as development toolkits for other programming languages, and can write and contribute their own plug-in modules.
Dragonfly (the BUG SDK) is a collection of plug-ins that contribute to Eclipse Platform.
More info about the Eclipse Platform can be found here.
Ethernet via USB
A method of networking which uses the USB bus as though it were ordinary Ethernet hardware.
General Purpose Input Output: An embedded bus used on the BUG. The BMI connector exposes GPIO ports. More information is available at Wikipedia.
Graphical User Interface: A way to interact with a system visually through icons, menus, and pictures.
A serial bus. This is an interface that is exposed in the BMI connector. More information is available at Wikipedia.
Image Processing Unit: a component in the BUG that handles image processing.
A jar is essentially a compressed zip file that contains Java code. The Dragonfly SDK packages BUG applications in jar files.
A SLP implementation used in the BUG and Dragonfly (the BUG SDK). SLP allows Dragonfly (the BUG SDK) to discover BUGs on the local network. More info about jSLP can be found here.
Java Virtual Machine: a program that executes Java programs. BUG uses the PhoneME Advanced CDC JVM.
Short for the Linux Kernel. BUG runs Linux version 2.6.19.
Short for Linux Target Image Builder. LTIB is a tool we use to generate our Linux kernel and Rootfs.
In an OSGi bundle, a manifest file is where metadata is stored. This file is in the /META-INF directory of the jar.
A modlet is a piece of Java code that gets executed each time a module is inserted or removed from a BUGbase.
Mongrel is an application server for Ruby web applications. It is often used behind more general web servers such as Apache or nginx in a clustered manner. In this arrangement, the general web server typically serves static content and hands off requests for dynamic content to the mongrel cluster.
The original BUG used an MMC card that contained the Linux Root files system (rootfs). The current version of the BUGbase uses SDmicro cards which contains the linux kernel (for uboot) and rootfs. User applications and data is also stored on this card.
The navigation buttons are to the left of the BUGbase LCD display. Up, down, left, right allow users to navigate the menu.
A lightweight, fast web server that has become very popular for hosting Ruby on Rails. It is pronounced "engine X". Nginx wiki
A console interface to the OSGi runtime. This console lets a user inspect the current state of the runtime system, start and stop bundles, and see what services are available. In addition, developers can add their own commands.
The bootloader used in BUG. Redboot loads the Linux kernel into memory and starts it. Redboot can be used to upgrade the kernel in flash.
Stands for Representational State Transfer. A style of web service architecture that uses HTTP verbs for CRUD (Create, Read, Update, Delete) actions on addressable resources. Resources are addressable via a uri. Typically these uri's are descriptive and easy to read. REST style resources are often called RESTful and they tend to be simpler than RPC-style web services, such as those that depend on SOAP.
Shorthand for Root Filesystem. This is the data structure where all files are stored on BUG.
Software Development Kit. The BUG SDK, also known as Dragonfly, is what you use to write applications for BUG.
SDmicro Card (Secure digital)
The current version of the BUGbase uses SDmicro cards which contains the linux kernel (for uboot) and rootfs. User applications and data is also stored on this card.
Service Location Protocol. A discovery protocol that allows various networked services to know about each other.
Short for "System on a Chip". The BUG CPU, Freescale's i.MX31, is a SoC. It combines several devices and interfaces that are typically found on separate chips in traditional designs.
Secure Shell: Network protocol used between two networked devices to directly access shell accounts (command-line user account).
TCP/IP over USB
Linux allows a special USB kernel module (g_ether) to be loaded that causes a USB connection between BUG and a computer to be used as a network connection.
Universal Serial Bus. BUG has one USB OTG (on the go) port. This port can be used to connect external peripheral such as hard drives and web cams. Additionally when connected to a computer with the correct settings, the USB connection can be used as a network device.
Virtual representation of BUG in Dragonfly (the BUG SDK). When developing BUG applications, users can transfer created application onto the Virtual BUG to see how it will behave on real hardware. Details about the Virtual BUG can be found here.
Web API, remotely accessible over a network.
