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.

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.

You’re validating email addresses all wrong!

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.

Escape from Agile

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.

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.

Agile Software is an Immortal Jellyfish

Dylan Herbert

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.

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

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.

DevOps for Robotics

Aaron Mavrinac

VP of Operations, Opreto

6 minute read

DevOps, a set of practices designed to automate and integrate the processes between software development and IT operations, has transformed how we deliver cloud and web applications over the past decade. Although the language used to illustrate these practices in books and courses is rather particular to that technical domain, the principles can apply more broadly. The world of robotics—specifically, mobile robots like self-driving cars and autonomous mobile robots (AMRs)—is a domain the usual language of DevOps doesn’t immediately conjure, but where its concepts can nonetheless flourish.

Content Addressing: Marvels & Magic

The technology of Content Addressing is marvellous. It is, ex post facto, a simple and powerful concept, demonstrably elegant and the basis for many of the most interesting and powerful technologies of the past two decades. I have already written about Why I love the InterPlanetary File System, and touched on Content Addressing in my post about Installing and Running an IPFS node, but it is constantly remarkable to me that this approach underpins blockchain networks like Bitcoin, version control systems like Git, and file distribution networks like BitTorrent as well. Content Addressing has changed the way we interact with and share key data, but I don’t think it gets the recognition it deserves, as a seminal building material of the modern Internet. Luckily, there is one surefire way in 2023 to communicate just how cool something is - describing it in terms of a Dungeons & Dragons tabletop roleplaying game!
