Computed Properties vs Functions – Why Does It Matter?

by

Cookies

What’s your favorite chocolate chip cookie recipe? I bet you could ask that question to 5 different people and get 5 totally different recipes… brown sugar vs white sugar, cake flour vs all purpose, dark chocolate vs milk chocolate. All of these recipes result in a chocolate chip cookie but the process by which we get there is a matter of personal preference.  If you were to ask multiple developers to solve a problem, it’s doubtful that any two developers write identical code.  It’s not that any one solution is necessarily better than the others… the resulting code is likely just a matter of personal preference.

Introduction to Blockchain

by

The term blockchain has been floating around both the tech and finance communities a lot in recent years. But what is blockchain?

Blockchain is a digital ledger of all transactions across a peer to peer network. Each user in the network will have a full copy of the whole blockchain, which includes data of all transactions. Let’s say a user wants to pay another user. He would encrypt the transaction and broadcast it to the network. The transaction gets put into a new block. The ledger is maintained by miners, who work to approve the transaction and validate it using cryptographic techniques. Then the block is added to the blockchain.

A Brief History of Jet Engines

by

The Wright brothers could not have imagined that their visionary insight would help man fly faster than sound just a few decades later. Aeronautics made great strides in the early 19th century, and the war time efforts during World War I and World War II pushed aircraft design and manufacturing to new heights.

Preventing Bloated View Controllers with Coordinators in iOS

by

A cartoon image depicting a coordinator pattern.

Overstuffed View Controllers: a problem that is universally despised by iOS developers the world over. Who hasn’t had their eyes glaze over while staring down debugging a 3000 line VC? View Controllers can control so much information, and Apple seems to have very few opinions on where specific logic should go. They give us the decision making power. How can we prevent against this annoying problem and modularize our apps better? Model–View–View Model (MVVM) can certainly help with this, but ultimately leaves routing to View Controllers, which doesn’t make the most sense. This is where a Coordinator comes in.

Learning from Project Retrospectives

by

Overview

Grio has adapted the Agile methodology to our consulting business; and one of our most valued “ceremonies” is the retrospective. We keep these meetings open to all, and the notes from these meetings are in a shared folder for everyone at Grio to read.

Despite having access, I found them “gathering dust” so to speak, and decided to dig through the entire folder to track Grio’s ability to implement the changes proposed and avoid the pitfalls of previous projects. We’re genuinely asking ourselves, “Are we serious about learning from mistakes?”

I’ve explored the overall process of my research here, and have presented the findings in depth to our entire team. There’s some good news, and some work to do; but we’re happy to see that our efforts have created tangible benefits to our team, our clients, and our bottom line.

We’re asking ourselves:

“Are we serious about learning from mistakes?”

Women in Computer Programming History

by

There has recently been much discussion about getting more women into computer programming roles – the case of the Google manifesto shows that what many us think of as outdated gender stereotypes about programmers are still alive and well in some circles.  However, it wasn’t always the case that computer programming was considered a ‘male’ field.  Early computer programming was dominated by women, and it was women who were seen as uniquely capable of being computer programmers.  Among early computer pioneers were many women who made important contributions to computer science and programming and invented many of the concepts & models we continue to use today.

What Is a Design System and When to Create One

by

Throughout my continuing journey as a designer I have started to notice several companies are creating what they call design systems. Some people also like to refer to them as design languages, visual languages, or human interface guidelines. Google has Material Design, Apple has created their Human Interface Guidelines, last year Salesforce put together their Lightning Design System, and Airbnb has recently put together a visual design language for their design team. I became curious as what a design system is and why these companies have started to create and document them. Below I’ve broken down my research into a few sections: what is a design system, what are the benefits, and when it is and isn’t beneficial to create one.

Improving Supply Chain Management with Software

by

By definition, Supply Chain Management (SCM) is the oversight of materials, information, and finances as they move in a process from supplier to manufacturer to wholesaler to retailer to consumer. Supply chain management involves coordinating and integrating these flows both within and among companies.* SCM is becoming evermore important for small businesses as larger companies they compete with invest more in transportation, logistics, and inventory.

The Elements of Style

by

A spate of applications have popped/cropped up in recent years with slogans like “Make Anything Art.”  They purport to transfer the style of one image and render the content of another image in that style.  In the sets of images below, the small inset image is the source of the “style” which is transferred to the larger image.  It’s an impressive trick, although I don’t know that it accurately represents what we mean by ‘style’.
