The general definition associated with decentralized applications (DApps) is an application that functions through a peer-to-peer network as opposed to a single source or computer. The existence of such an app in cyberspace does not depend on a single authority. It can operate under a blockchain network or any other form of the peer-to-peer system (read more about blockchain here). Moreover, it is important to understand that the definition of these applications can differ with respect to the institution. The notion of blockchain originates from the concept adapted by bitcoin which uses cryptographically-stored records. There are limited tokens in the system as a means of checking the value of the currency. Different DApps exist for different purposes but the key property of the application is the independence from a traditional single server database.
My goal for this post is to share how I answered a seemingly simple question — what should I learn in my free time?
While developing software in Silicon Valley is educationally rewarding on a daily basis, there is still so much more to learn. Tech news is constantly bombarding readers with new technologies like blockchain, machine learning, and autonomous-(insert vehicle type here). Staying ahead is exciting for me, but also critical to my career.
I considered a few ways figure out what is “hot”:
In an attempt to understand the technical side of the cryptocurrency craze, I read the book, Bitcoin and Cryptocurrency Technologies (http://bitcoinbook.cs.princeton.educeton.edu). It was a great book and I’d highly recommend it. What follows is somewhat of a book report on the beginning chapters, a look under the hood at what a blockchain is.
It has been observed that the acceleration of Moore’s Law has left tech culture with a tendency to discount the past, which leads to issues when building for the long-term. If everything we do is going to be circular filed in a few years anyhow, why bother? I think we’re starting to see some of the limits of ahistorical strategies, especially because building for internet scale means that systems can affect higher-order aspects of society and culture in unexpected ways. This is why I want to talk a little bit about cybernetics.
“But you are planning for failure!”
The planner on my project team was aghast. I had asked for components to cover a 3% predicted waste rate for a multi-year program making assemblies destined for orbit. As the manufacturing engineer for the program I knew from previous experience that 3% was an average, and not unreasonable, estimate of possible loss. This blog post attempts to answer whether her reaction was justified, but in the context of software development. Was she right to criticize my analysis of previous wastage of these components?
Rails is a popular Ruby Web Application Framework
Ecto is a DSL (Domain Specific Language) for database adaptors in Elixir.
Preface: The intention of this article is to provide an interesting and simplified starting point for introducing someone to functional programming topics. It is not intended to be a mathematically provable language or even a full featured programming language.
A mobile app is a great way to bring new ideas to life, add value for your customers, or boost awareness of your business—but only if you can build a quality mobile experience without breaking the bank. And nailing down the cost of an app in advance isn’t exactly easy. App development costs can range from trivial to extreme, depending on a host of factors such as what your app does, how users will interact with it, and how you plan to staff the project.
If you work in the tech industry, coding bootcamps are something you have probably heard of, possibly attended, or know someone that graduated from one. For those of you who are unfamiliar with the term, the industry of coding bootcamps is fairly new, with the first ones starting around 2011-2012. In the short time they have been around, these alternative education programs have gained significant popularity, making their presence known in the tech world.
