Ancient Grudges

by in CodeSOD on

Ignoring current events, England and the rest of Europe have had a number of historical conflicts which have left a number of grudges littered across the landscape.

Andro V lives in Norway, but is remotely collaborating with an English developer. That English developer wants their peers to know that Sweyn I and Thorkell the Tall’s invasions of southern England will never be forgotten.


The Value of Your Code

“We know that governmental data-systems aren’t generally considered ‘cutting edge’ or ‘well architected’, but we’ve brought together some top flight talent, and we’re building a RESTful architecture that guarantees your code gets nice, easy-to-consume JSON objects.”

That’s what Oralee B. was told when she was hired to work on it. The system owned pretty much the entirety of the municipal data management market, tracking birth certificates, marriage certificates, death certificates and pet licenses for nearly every city in the country. JSON is so simple, how can you screw it up?


The God Page

Mike inherited a data-driven application. Once upon a time, it started out pretty well architected. Yes, it was in PHP, but with good architecture, solid coding practices, and experienced developers, it was simple and easy to maintain.

Time passed. The architects behind it left, new developers were hired, management changed over, and it gradually drifted into what you imagine when you hear "PHP app" in 2019.


Offensively Defensive Offense

by in CodeSOD on

Sometimes, the best defense is a good offense. Other times, the best offense is a good defense. And if you’re not sure which is which, you’ll never be a true strategic mastermind.

Tina’s co-worker understands that this is true for defensive programming. Always, always, always catch exceptions. That’s a good defense.


Switching to Offshore

by in CodeSOD on

A lot of ink has been spilled talking about the perils and pitfalls of offshore development. Businesses love paying the wage arbitrage game, and shipping software development tasks to an outside vendor and paying half the wage they would for a dedicated employee.

Of course, the key difference is the word “dedicated”. You could have the most highly skilled offshore developer imaginable, but at the end of the day: they don’t care. They don’t care about you, or your business. They don’t care if their code is good or easy to maintain. They’re planning to copy-and-paste their way up the ranks of their business organization, and that means they want to get rotated off your contract onto whatever the next “plum” assignment is.


Virtually Careful

by in CodeSOD on

Inheritance is one of those object-oriented features whose importance is perhaps overstated. When I was first being introduced to OO, it was a lot of “code reuse!” and “polymorphism!” and “code reuse!” In practice, inheritance is usually a way to tightly couple two different classes and create more headaches and rework in the future.

That’s why many OO languages favor interfaces, and why the classic Gang-of-Four patterns emphasize the importance of composition in many situations. And, because inheritance can make things complicated, most languages also require single parent inheritance.


For Each Parallel

by in CodeSOD on

Parallel programming is hard. For all the advancements and tweaks we've made to our abstractions, for all the extra cores we've shoved into every CPU, deep down, software still carries the bias of the old uni-tasking model.

Aleksei P works on a software package that is heavily parallel. As such, when interviewing, he talks to candidates about their experience with .NET's Task objects and the async/await keywords.
