The Plight of the Power User

2 minute read

The 1980s. A simpler time, when hair was big, music was loud, and computer interfaces were… well, let’s just say they weren’t exactly what you’d call user friendly. Unless, of course, you were one of the chosen few. The elite. The engineers and the proto-geeks. For some of us born at the cusp of the digital dawn, the call to wield that power was irresistible. In those days, computers were still sufficiently arcane that conjuring buxom women, hacking land yacht races, and triggering global thermonuclear war were all plausibly within the domain of the initiated teen. Their UIs—BASIC on a home computer, the UNIX shell on a terminal at the local university—was about as welcoming as a secret society’s handshake. They were cryptic, esoteric, and utterly fascinating. Designed by engineers for engineers, these interfaces were a test. Pass, and you were in the club. Fail, and well, maybe a typewriter was more your speed. And so we, the early adopters, the tinkerers, the ones already predis...

To Olympus: Replatforming on the Cloud

Dylan Herbert

VP of People, Opreto

There is a particular synergy that springs from engaging an agile software development agency as an integrated software partner, and having them platform your software into the cloud. The sum of the two is truly greater than its parts. When launched together, the entire tech saga becomes truly epic for your business; you are freed to focus on your business, and we carry you up on our back. Do not fret, good citizen, we’re here to help. If you’re building software in the cloud for clients, like we do, you must conduct yourself as a hero. Although the path to the summit is well trodden by now (decades after the concept of the cloud was first popularized) it is still necessary for some chosen few of us to carry and guide, as some of you have not yet reached the cloud on your own. There are a thousand possible reasons for that, but every obstacle can be defeated with the right team and technology. As agile developers, we clear every engineering challenge from the critical path for you...

8-bit Makes a Better Programmer

VP of Operations, Opreto

In the realm of modern programming, with its high-level languages and sophisticated development environments, the art of programming an 8-bit microcomputer might seem like a quaint, if not obsolete, pursuit. However, diving into the world of assembly language programming on such a system isn’t just a nostalgic trip down memory lane; it’s a journey that offers invaluable insights and a deeper appreciation for the inner workings of computers. Modern software development would be almost unrecognizable to the microcomputer programmer of forty years ago. At a basic level, the languages and concepts wouldn’t be too foreign: we still write if statements and for loops, and object-oriented programming was already in vogue by 1984. But modern applications are internet-centric, use GUIs and 3D graphics, rely on distributed version control and CI/CD to get built, depend on various runtimes and interpreters, and above all, sit so high in an immensely complex hierarchy of abstractions that it’s ...

Threat Categories, Attack Patterns, and Countermeasures: Safeguarding Against Cyber Vulnerabilities

Recently, our community in Windsor, Ontario, Canada, experienced a harrowing cyber attack on our healthcare system. The electronic systems that the hospital system relied on suddenly became useless, forcing workers back to the rudimentary pen-and-paper methods. This sudden regression in technology not only disrupted healthcare operations but also painted a stark picture of our vulnerabilities in the digital age. This incident was more than just an inconvenience; it was a dramatic step backward, highlighting the urgent need for resilient cybersecurity measures to protect our most critical services and data. Understanding these threats involves more than just preventing attacks. It’s about knowing different types of risks and patterns attackers use, like phishing - deceptive emails or messages aiming to steal sensitive information, and ransomware - malicious software that locks out users from their systems until a ransom is paid. Being aware of these tactics is crucial in developing ...

I Went to a Remote Cabin to Hunt Deer and All I Found Was Agile

I was stunned to realize my father in law, a man in his 70s, is a practitioner of Agile. I found this out at Deer Camp, the remote off-the-grid cabin in the thick woods of the Upper Peninsula of Michigan, where the men of my wife’s family gather every year to hunt deer. I went there with the expectation of a digital cleansing of some kind, I think, or some grand hermitage away from civilization. But instead I found reinforcement for everything we do in my high tech job @Opreto, and realized during my time there that our hunting cabin uses good Agile practices. It seems clear to me now that something I thought of as modern is actually quite old, and that an “agile team” approach to deer hunting is as natural as an agile approach to software development, although there are arguably fewer websites disclaiming this fact to hunters than those proliferating on blogs about software development. This realization felt like a bit of a shock when it first occurred, but really it is part of th...

You’re validating email addresses all wrong!

Xavier Spriet

VP of Technology, Opreto

Ever tried entering your email address, only to receive a “Please enter a valid email address” error? Frustrating, right? There’s a lot more to email validation than just spotting an ‘@’ and a ‘.com’. Dive into the world of RFCs where email addresses are not just strings, but a complex interplay of rules and standards. From the subtle nuances of RFC 5321 and 5322 to the curious world of quoted strings and dot-atoms, we’re tackling the real challenge of validating emails. Because let’s face it, nobody wants to be told their perfectly good email is “invalid” – especially not by a machine. Imagine you’re tasked with building a form to collect email addresses for a client. Simple enough, right? At first glance, it appears trivial, but the real challenge lies beneath the surface: ensuring the validity of these email addresses. This goes beyond the basic checks for an ‘@’ symbol or a domain suffix. It delves into the intricacies of what constitutes a valid email address according to est...

Escape from Agile

Aaron Mavrinac

VP of Operations, Opreto

I discovered Erich Fromm’s Escape from Freedom a couple years ago, via the Philosophize This! podcast. In this work, Fromm dissects the human psyche’s intricate dance with freedom and authority. His thesis pivots around a paradoxical tendency in human behaviour: the flight from the liberating yet daunting responsibility that freedom entails, seeking refuge in authoritarian structures. While Fromm was reacting to the rise of fascism in Europe at the height of World War II, having fled Nazi Germany himself, it occurs to me that some of his observations are relevant to a matter more mundane: the resistance we often encounter to fully embracing Agile principles. Fromm posits that individuals often gravitate towards authoritarianism to escape the burdens of freedom—making choices, and shouldering responsibility for those choices. Agile, with its ethos of flexibility, adaptive planning, and shared responsibilities, deviates sharply from the more rigid, hierarchical structures of traditi...

Cognitive Biases in Agile Estimations and How to Avoid Them

Alan P. Laudicina

President, Opreto

7 minute read

Cognitive biases, often unconscious influences on human judgment and decision-making, can significantly distort the accuracy of Agile estimations. These biases, like invisible bugs in our mental software, can lead to errors that affect the outcomes of project planning. Whether it’s anchoring to the first piece of information heard or overly optimistic predictions about project timelines, they can subtly undermine the efficiency of even the most experienced Agile teams. In Agile software development, estimation is a critical process that determines project timelines, resource allocation, and, ultimately, the success of a project. The accuracy of these estimations is important but frequently jeopardized by the human propensity to cognitive biases. As teams increasingly implement “Sprint Poker,” a blind team-based estimation game for gauging task complexity, recognizing and addressing these biases becomes crucial. Let’s move from theory to practice and see how these biases play out d...

Agile Software is an Immortal Jellyfish

Dylan Herbert

VP of People, Opreto

Anyone who has ever purchased software is aware that it must be updated occasionally to a new release, with new features and security and performance updates. And anyone with a huge reliance on the work facilitated by that software is acquainted with reading changelogs to stay current with changes that have been made, as the changes may often impact the end user and how they use the tool. Software should never stop moving or be allowed to become static. The moment a codebase stops changing, it becomes vulnerable to software rot; a gradual decline in responsivity and updates with respect to the changing environment in which it resides. As the digital world becomes more complicated, and attack vectors become more nuanced and intricate, software needs to stay abreast of changes or it falls behind and develops new vulnerabilities. This is easily understood from a naturalistic viewpoint as being analogous to rot, although it is in fact standing still and not changing at the same rate as ...

Metrics as Beacons, Not Scorecards: My Take on Software Metrics

Xavier Spriet

VP of Technology, Opreto

Metrics in software development are like fire - handy but dangerous if not handled correctly. Let’s get into a topic that deserves a brighter spotlight: the Hawthorne Effect. This phenomenon describes how people change their behavior when they know they’re being observed. Knowing that metrics like sprint velocity, build frequency, test coverage, or codebase contributions are being scrutinized can shift the team’s focus from delivering value to gaming numbers. Why is the Hawthorne Effect so critical in modern software development? Imagine a development team keenly aware that sprint velocity is being monitored as a performance indicator. The team might be tempted to inflate story points or cut corners to complete tasks faster. Similarly, focusing on build frequency could lead to more frequent but less meaningful builds. And let’s not even get into how aiming for high test coverage could result in poorly designed tests that tick a box but don’t enhance code quality. Joel Spolsky warne...
