Fixed point math in Solidity
It always seems impossible until it’s done. — Nelson MandelaIntroductionAny financial application with a minimum of complexity will need some decimal support and multiplications to calculate things like interest. In the case of CementDAO we needed logarithms to implement the transaction fee curve that steers its cryptocurrency basket towards the desired configuration.Solidity supports integers but no decimals, so we coded a fixed point arithmetic contract, made it safe against overflow, and tested it extensively. It underpins the CementDAO deployment in Ropsten.The Fixidity contract is available from the CementDAO github with a MIT license, please feel free to use it and build upon it.ImplementationIn order to code this we went from the simplest to the most complex arithmetic functions, (...)
The future of software development: modular, intelligent, and rickety
The future of software development: freelance, AI-assisted, and ricketyNearly four thousand years elapsed between when Egyptian astronomers invented the concept of zero and a British mathematician tacked together the first computer. But once the thing was made, we were off to the races. It was only 130 more years to electronic computers, 40 to the internet, and only nine to smartphones. Now advances in computer science pop off as if discharged from a ticker tape machine.But not everything that earns press sees success — or has an impact. Most inventions die following their hype cycle, in what research firm Gartner calls the trough of disillusionment. In this article, I’ll share three signals amidst all the noise that I think indicate trends that will survive to become the biggest forces in (...)

Semantic Versioning 101
Semantic Versioning 2.0.0 (semver.org) is a robust and elementary standard that encapsulates a wealth of information about the software you’re publishing or consuming.Open source veterans know and understand the importance of this standard. If you’ve run a project in long-term maintenance mode, you come to realize its power one way or another. Still, enthusiastic, fast-moving dev teams like to find ways around this standard. I’ve seen more than a few engineers decide to invent their own ideas around major, minor, and patch increments. Their rationale is rooted in aesthetics or their own release schedule.A key principleAside from the concise and complete information at semver.org, it is critical to understand:Semantic versioning is for your consumers. It’s not for your release schedule or (...)
Why “FREE” Isn’t Your Answer to Help Authoring Tools
Originally published by Catherine Heath at document360.ioInvesting in your documentation is now essential. 39% of millennials will check a company’s documentation before contacting support for help, and self-service is now an expected part of your support strategy. Help Authoring Tools (HATs) are a useful addition to any business — whether you have teams of technical writers, just one, or other employees pitching in, producing documentation remains essential for teams who want to improve their products or comply with regulations.HATs are typically used to help you produce large amounts of documentation that is centrally managed by your technical writing team.Some common Help Authoring Tools are industry standards like Madcap Flare or Adobe RoboHelp, and they enable you to single source (...)
#blockchain as the Next Evolutionary Step of the Open Source Movement
Lumi #blockchain WalletOpen-source is one of the major concepts in the #cryptocurrency space as the whole industry basically grew up on it. Nowadays, building a crypto project without publishing at least a part of your code on #github is considered to be bad manners.Most of the developers involved in open-source projects are driven by the same goal: create a product that they will use themselves. This way, you get deeply involved and know about every single issue at stake. Could you think of better motivation?But there’s a flip side to this. Running a business based on an open-source model can be rather tricky.Firstly, you have to consider that it’s going to, at the very least, double the duration of the whole development process. And, since the issue of time can be especially critical for (...)
How to Deploy a #parachain in just 1 minute?
Since the last half year, we have seen a downturn of the crypto-markets and the rise of public chains. Almost every week, there are a lot teams announcing their plans of launching public chain. The unprecedented passion for public chain makes an illusion that building a public chain just needs to set up several nodes.However, Rome was not built in a day.The establishment of a public chain is not an easy task. Even the top cryptocurrency exchange, HUOBI has not given a clear declaration of the launch date after investing 30 million HT to develop the public chain(nearly more than 600 million RMB). Actually, the development of public chain requires very large R&D investment, as well as the technical team support and maintenance cost. Also, it is quite costly to organize a large number (...)

Progressive Web Apps: Apple App Store, Google Play Store, It Was Nice Knowing You
Is the end coming for the Apple App Store and Google Play Store? The title is obviously an exaggeration, but in all seriousness, the time has come for a new wave of #mobile technology to come to the fore. In 2018, Twitter announced that it has started offering its mobile PWA as its main site. PWA? What’s that?Progressive Web Apps (PWA) is the future of mobile apps and the web, pushed by heavyweights in the industry especially Google. With features such as adding to home screen, offline support, push notifications and more, a PWA offers a user experience approaching that of a native mobile app.Here’s how a PWA works. Imagine you have a Customer Relationship Management (CRM) app that is also PWA compliant. You just need to visit the app using a normal URL in your mobile browser. If you have (...)

And making open source alternatives — #DevStoriesThis is a transcript of a talk I gave at the Hacker Noon #devstories @Github event, with minor modifications to improve readability. I wanted to call out the irony that security calls for openness, but security is also the reason for obscurity and proprietary implementations, especially in the hardware world. Making security more open is what motivated us to found SoloKeys, and make open source hardware security keys.▻https://medium.com/media/6a0e0d8f7709f7937cc7221c95a19eaa/hrefWhat I think is really fascinating about security is the duality that I tried to capture in the title between openness and obscurity.Borrowing a definition from cryptography:A (crypto)system should be secure even if everything about the system, except the key, is (...)
Muttniks : An open source dapp to show you how we built Astro Ledger
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 (...)
A Quick Introduction to Artificial Intelligence, Machine Learning, Deep Learning and #tensorflow
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 (...)
Fescar: A Distributed Transaction Solution Open Sourced by Alibaba
To support microservice-based development, Alibaba has now launched Fescar, an open source version of its Global Transaction Service solution to the problem of distributed transactions.This article is part of the Alibaba Open Source series.In online systems, #microservices have gained recent support from developers as a means of reducing difficulties, enhancing scalability, and facilitating agile development by splitting complex applications into loosely coupled services. However, implementing a seemingly simple function in a micro-serviced system may require calling multiple services and operating multiple databases, introducing a formidable distributed transaction problem for service calls.Currently, distributed transactions are the greatest obstacle to realizing microservices, and (...)
Public Invention Project #40: A Wheel for #painting Very Thin Lines
“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 (...)
