A sneak peek into the Muttniks kennel.IntroductionLaunching a dapp may not be as hard as launching a rocket… but it’s no moonwalk, either. A dapp, portmanteau of “decentralized app,” is any app that runs on decentralized infrastructure, like on #ethereum. For your coding pleasure, our team is happy to present Muttniks, a friendly Ethereum #space doggo “kernel” (or kennel) that you can build from the comfort of your spacecraft. Muttniks is an open source sample dapp, built to guide you through our exciting journey with Astro Ledger. Like the real stars and planets featured on astroledger.org, you can securely adopt, name, and trade Ethereum space doggos with Muttniks (and then donate your testnet ETH to build more Laika monuments). The following is a step-by-step technical exploration of the (...)

What used to be just a pipe dream in the realms of science fiction, artificial intelligence (AI) is now mainstream technology in our everyday lives with applications in image and voice recognition, language translations, chatbots, and predictive data analysis.In this article, we’ll introduce AI along with its related terms machine learning and deep learning. By the end of the article you should understand these terms, how things generally work and be more familiar with terms like Inception and YOLO (and no, we’re not talking about the Leonardo DiCaprio movie or some internet meme).Artificial intelligence (AI) is the simulation of human intelligence by computers. Machine learning is a branch of AI where algorithms are used to learn from data to make future decisions or predictions. Deep (...)

“Oyarsa”, by Robert L. ReadI probably should not have taken up oil painting; I have always admired #art done with pen-and-ink, which produces very thin, precise lines.It is possible to make thin lines with oil paint, but it is difficult. One must either have a terribly steady hand with a very fine brush, or use a ruling pen, which are themselves tricky and require very thin paint.Following some other artists, I bought a cutting wheel, and used it to make the painting “Oyarsa” above, an attempt to depict the archangel, or genius locii, of Malacandra, from C.S. Lewis’s Space Trilogy. I jammed a wad of cotton against the wheel in the handle, to make the loading of the wheel with paint last a little longer. I put paint in a little tray, and loaded the wheel by rolling it back and forth. I could (...)

From version 1.1.0 to 1.6.0, Apache Flink’s relentless improvement exemplifies open-source development.Open-source big data computing engine Apache Flink, or Flink for short, has gained popularity in recent years as a powerful framework for both batch processing and stream processing that can be used to create a number of event-based applications.Flink is first of all a pure stream computing engine with a data stream basic data model. A stream can be infinite and borderless, which describes stream processing in the general sense, or can be a finite stream with boundaries, as in the case of batch processing. Flink thus uses a single architecture to support both stream and batch processing.As conveyed by its slogan “Stateful Computations Over Streams”, Flink has the additional strength of (...)

Before that we had high profile startups Confluent (behind Apache Kafka with circa $205m raised to date) and MongoDB Inc (now a public company) change their licences. These licence changes are according to their executives necessary to protect against what they perceive as unfair practices from big cloud vendors (Amazon Web Services often cited as biggest culprit) — who do not make significant contributions (or none at all!) to open source projects and yet fork projects to create competing hosted services.

“Treat open source as open source treats you.”The Golden Rule is the principle of treating others as one’s self would wish to be treated. It is a maxim that is found in many religions and cultures and it is considered an ethic of reciprocity. It is expressed usually in the form: “One should treat others as one would like others to treat oneself.” If you think of open source as a business model, or culture, or religion, you will see that the Golden Rule applies here as well. If I were to phrase the Golden Rule of open source, I’d say: “Treat open source as open source treats you”.Image by Internet Archive Book ImagesReciprocity is behavior in which two people or groups of people give each other help and advantages.

Many companies around Open Source projects make money by also selling licenses to some additional proprietary software but all companies around proprietary software sell licenses.Selling licenses is hard in the presence of cloud providers because cloud providers have a better product, they sell the whole thing, while a license is only a part of the solution.

The open source #software movement came from a widespread revolution, completely altering how software was developed — leading to the most commonly accepted community generated software development method — widely accepted over the last 40 years.Initially, programmers could not come up with a good name for such an unusual idea or its possible applications. Software was always developed in house, by companies and conglomerates. However, the open source methodology quickly became (and still is) the most widely used software design and development method, lending us many popular and stable software (...)
