Tons of software development projects tend to fail after launch for various reasons, of which the primary one is the lack of clear goals. Another almost equally significant but underestimated cause of failure is that a considerable number of these startups were solving the wrong problem.This situation is like a case of going a hundred miles per hour in the wrong direction and is quite common in the software development industry, but often binned under the ‘incompetence’ category (although, admittedly, that does play a role in some cases). It is an issue of poor communication between the parties involved.An ideal project would mean that all the organization’s staff at every level, as well as the target users, would be utterly convinced about the need to product and its ability to solve the (...)

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.

Custom software development is when specific software is tailor-made to fit business’ unique requirements. So, the question “How long does it take to build a custom software” has no direct and instant answers. It’s always an estimate — an estimate that we provide to our clients keeping a lot of factors in mind. Read the article to know what are the factors that one needs to consider to provide an accurate time estimate for your custom software and how long a particular stage of software development can stretch.How long will it take to build my custom software application?

Become a better programmer by building a routine and habit for reading codeThis is a post in my occasional series, Notes to a Young Software Engineer. Sign up here.A code snippet from RedisIf you woke up one day resolved to be a great writer, you’d hear two simple pieces of feedback: write a lot, and read even more.In software, plenty of people write code, but precious few spend time reading it — especially code outside their day to day work. That is a mistake. Early in your career, act like an aspiring writer and embrace reading diverse code.Read widely and read often. It could be the difference between being a decent software engineer and a great one.Why should I read code?Great writers are a function of the writers they’ve read.

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.

The REAL kata!While we, as software system developers, certainly know that our day to day work can bring a lot of satisfaction and improvement to our profession, there prove to be other ways that we can also try out to flex our coding “muscle”. “Kata” is a term borrowed from the world of martial arts. According to Wikipedia, a kata “is a detailed choreographed pattern of movements made to be practiced alone, but are also practiced within groups and in unison when training.” That sounds a bit different that what you might’ve expected. But if you think about it, our coding craft is not that much different. We practice a pattern of strokes, sometimes alone, but also in groups, you might know as teams, or pairs, that sometimes translate into pair programming sessions.The term “kata” in regard to (...)

Most crucial aspects of our life including our finance, identity, and healthcare now depend on code. Software security is now a critical aspect for not just companies, but individuals as well.In the latest circumstances, we see that software security concepts should be understood at least on a basic level by anyone who is using modern software products and services. And for any developer that works on designing, creating or maintaining these products and services, a comprehensive understanding of security vulnerabilities and security best practices is a must to avoid security breaches that may now cost much more than ever.Most of the time, security vulnerabilities seem to us far and unfamiliar; they are potential issues to us that are not entirely tangible; thus easy to neglect. (...)

Estimation — how can we estimate with confidence in software development?Introduction‘When will it be done?’ is one of the most common and difficult questions to answer in software development.Estimating in software is traditionally difficult, inaccurate most of the time, with project teams spending a significant amount of time on the process.There are a number of contributing factors to this. Part of it is that software development is a design activity, and thus hard to plan and estimate. Software is done with people, and it depends which individual people are involved. Individuals are hard to predict and quantify and humans in general are inherently bad at predictions [1]. Those teams that build the software are operating in an ever-changing business and technology landscape.The cost of (...)
