Pandora (computer)

Pandora (computer) is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Pandora (computer) rather than just read about it. In short: The Pandora was a handheld gaming computer developed and produced by OpenPandora, which is made up of former distributors and community members of the GP32 and GP2X handhelds. Originally released in 2010, it was designed to take advantage of existing free and open-source software and to be a target for homebrew development.

Key takeaways

  • Pandora (computer) belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Pandora (computer) to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Pandora (computer) from memory before moving on to harder problems.

Reference excerpt

The Pandora was a handheld gaming computer developed and produced by OpenPandora, which is made up of former distributors and community members of the GP32 and GP2X handhelds. Originally released in 2010, it was designed to take advantage of existing free and open-source software and to be a target for homebrew development. The Pandora runs Linux and uses an ARM processor. Until 2013, multiple batches of slightly updated Pandora variants were produced. In 2014, development of a redesigned and upgraded successor, named DragonBox Pyra, began.

History

Development of the Pandora began when Craig Rothwell, Fatih Kilic, Michael Mrozek and (later) Michael Weston teamed up and planned a portable system that would excel in the areas where they thought the GP32 and GP2X systems (from Game Park and GamePark Holdings respectively) were flawed. The Pandora was designed based on ideas and suggestions contributed by GP32X forum members, with the goal of creating the ultimate open source handheld device. When announcing the system, the designers of Pandora stated that it would be more powerful than any handheld video game console that had yet existed. The final case and keymat design was made by Dave Cancilier (DaveC), who was known on the forums for custom hardware modifications. In February 2008 the Pandora wiki had already been created; as of 2014, it contains a thousand pages and is translated with the MediaWiki Translate extension. The initial development and setup costs were funded through a crowdfunding approach where early supporters provided enough money to support a production run, and when the console made it into production, each supporter would receive the device they paid for (what actually ended up happening due to cost overruns is that the early supporters received devices as later sales recouped the initial investment costs). OpenPandora began taking payments on September 30, 2008 and began shipping to customers on May 21, 2010. In late 2011, after production problems, OpenPandora shifted its production from Texas to Germany, delaying production, and the device was upgraded from 256 MB to 512 MB RAM. As of September 3, 2012, 4600 units had been shipped and 400 early supporters were still waiting to receive a console, as these pre-orders are only fulfilled when sales to new customers are made. Since June 2012, a new 1 GHz model has been made available in limited amounts during the summer 2012. Due to the shortage of previous 600 MHz chips, this new model has become the de facto standard in 2013. In March 2013, the pre-order queue of the German OpenPandora GmbH company (owned by Michael Mrozek aka EvilDragon) was finally cleared. The remaining pre-order queue of the UK OpenPandora Ltd. company (owned by Craig Rothwell) turned out to be significantly larger than originally reported, and the UK company has requested to be struck off. This means that the original pre-orderers at the UK company are unlikely to ever get their unit from the UK company. Also because of this, buyers have lost their money. Although there is no legal connection between the two companies, the German OpenPandora GmbH company is trying to help those UK customers by offering them significant discounts (if they decide to buy a unit from the German company instead of waiting for the UK company) and by organizing community donations to get them peer-funded units. As of December 2, 2013, about 6000 units have been shipped. On November 19, 2013, it was announced that production of the final Pandora batch had begun. About 7500 Pandoras have been made and sold altogether between 2010 and 2014, with further production made impossible due to shortage of Wi-Fi chips. In 2014, the OpenPandora project opened the hardware design files to the community, making the OpenPandora a type of open source hardware. Speculation and discussion about a successor to the Pandora began on the OpenPandora boards. Features and a demo prototype were announced at FOSDEM 2014. The project is named DragonBox Pyra.

Worked examples

Example 1 — a first encounter with Pandora (computer)

Start with the simplest possible case. Write down what Pandora (computer) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Pandora (computer) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Pandora (computer) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Pandora (computer)

In research
Pandora (computer) appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Pandora (computer) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Pandora (computer) is common in secondary-school and first-year university syllabi. It links to neighbouring topics ARM-based computers, Computer-related introductions in 2010, Embedded Linux, so understanding it makes those chapters shorter.
In everyday life
Look for Pandora (computer) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
