Jelly (app)

Jelly (app) 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 Jelly (app) rather than just read about it. In short: Jelly was a Q&A platform app which was created by Jelly Industries, a search-engine company founded and led by Biz Stone, one of Twitter's co-founders. In March 2017, Jelly was acquired by Pinterest for an undisclosed amount.

Key takeaways

Jelly (app) 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 Jelly (app) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Jelly (app) from memory before moving on to harder problems.

Reference excerpt

Jelly was a Q&A platform app which was created by Jelly Industries, a search-engine company founded and led by Biz Stone, one of Twitter's co-founders. In March 2017, Jelly was acquired by Pinterest for an undisclosed amount. Jelly differentiated itself from other Q&A platforms such as Quora and ChaCha by relying on visual imagery to steer people to getting better answers from within and outside their social networks. In particular, it encouraged people to use photos to ask questions.

History AllThingsD reported on March 28, 2013, that, according to sources, Twitter co-founder Biz Stone was close to launching a native mobile app called Jelly. On April 1, 2013, Stone wrote the company's first blog post, giving only vague information about the product. A TechCrunch writer inferred that the product would be targeted at do-gooders on the go. Other news publications also published speculation about the app. In May 2013, while still in stealth mode, Jelly raised Series A funding from Spark Capital, SV Angel, Square CEO Jack Dorsey, Reid Hoffman, Al Gore, Bono, and others. The app release was announced, thereby bringing Jelly out of stealth mode, on January 7, 2014. The announcement was picked up by much of the technology press and mainstream press. Stone explained to TechCrunch that the primary goal of Jelly was not to help people asking questions but to improve empathy among people answering questions by making them feel helpful to people around them. In an interview with Bloomberg News, Stone said that he never intended to create a company with Jelly, and that it was largely accidental. The app was reviewed by Rachel Metz for Technology Review. The Next Web published advice for how brands could use the new app effectively. On January 23, 2014, Jelly announced that it had raised Series B funding from Greylock Partners. On March 31, 2014, Jelly updated its iOS app to the 1.1 version that allows users create questions using a map and a specific location. On March 8, 2017, Pinterest said it had acquired Jelly Industries.

Worked examples

Example 1 — a first encounter with Jelly (app)

Start with the simplest possible case. Write down what Jelly (app) 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 Jelly (app) 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 Jelly (app) 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 Jelly (app)

In research: Jelly (app) 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 Jelly (app) 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: Jelly (app) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2017 mergers and acquisitions, American companies established in 2013, Defunct social networking services, so understanding it makes those chapters shorter.
In everyday life: Look for Jelly (app) 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.
