OpenMicroBlogging

OpenMicroBlogging 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 OpenMicroBlogging rather than just read about it. In short: OpenMicroBlogging is a deprecated communication protocol that allows different microblogging services to interoperate with each other. It lets the user of one service subscribe to statuses from a user of another service.

Key takeaways

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

Reference excerpt

OpenMicroBlogging is a deprecated communication protocol that allows different microblogging services to interoperate with each other. It lets the user of one service subscribe to statuses from a user of another service. This enables the creation of a federation of new communities, as an individual or organization of any size can host a service that supports the protocol. OpenMicroBlogging utilizes the OAuth and Yadis protocols and does not depend on any central authority. OpenMicroBlogging has been superseded by an enhanced version of it, OStatus.

History The original implementation of the OpenMicroBlogging protocol is the Laconica software, which changed its name to StatusNet in August 2009. Identi.ca is the first service to support OpenMicroBlogging, and other sizeable services including Leo Laporte's Twit Army were amongst those powered by the open source software. Since March 2009, one can search users' accounts in TWiT Army from within Identi.ca. You could also subscribe to accounts at TWiT Army from your Identi.ca account. A third-party implementation of the OpenMicroBlogging protocol is the OpenMicroBlogger software.

Worked examples

Example 1 — a first encounter with OpenMicroBlogging

Start with the simplest possible case. Write down what OpenMicroBlogging 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 OpenMicroBlogging 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 OpenMicroBlogging 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 OpenMicroBlogging

In research: OpenMicroBlogging 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 OpenMicroBlogging 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: OpenMicroBlogging is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer network stubs, Microblogging software, so understanding it makes those chapters shorter.
In everyday life: Look for OpenMicroBlogging 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.

Frequently asked questions

What is OpenMicroBlogging in simple terms?

Why does OpenMicroBlogging matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study OpenMicroBlogging?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
