Intro to Functional Programming, With Emojis 💰🍺🔥
Preface: The intention of this article is to provide an interesting and simplified starting point for introducing someone to functional programming topics. It is not intended to be a mathematically provable language or even a full featured programming language.
How Much Does It Cost to Build a Mobile App?
A mobile app is a great way to bring new ideas to life, add value for your customers, or boost awareness of your business—but only if you can build a quality mobile experience without breaking the bank. And nailing down the cost of an app in advance isn’t exactly easy. App development costs can range from trivial to extreme, depending on a host of factors such as what your app does, how users will interact with it, and how you plan to staff the project.
The Rise and Future of Coding Bootcamps
If you work in the tech industry, coding bootcamps are something you have probably heard of, possibly attended, or know someone that graduated from one. For those of you who are unfamiliar with the term, the industry of coding bootcamps is fairly new, with the first ones starting around 2011-2012. In the short time they have been around, these alternative education programs have gained significant popularity, making their presence known in the tech world.
What Do We Look for in AI?
When we think of artificial intelligence at its peak, we usually think of one of two things: humans and robots coexisting happily together in society, or robots killing or enslaving humans. These are both very human things to want to do, and we have a storied history of doing both. These thoughts, or perhaps expectations, are informed by us, and the society we live in. As we develop artificial intelligence, we become robot parents, and we teach to our programmed children what we know.
Introduction to Mobile Cloud Platforms
If you are building a mobile application of any sophistication, you are likely to need some services to support your app. You’ll need a way to distribute your app for testing prior to submitting to the app store(s), as well as analytics, error logging, crash reporting, and possibly user and data management services. Of course, you could write these services yourself and provision servers to host these services, but why do that when you don’t have to?
Mobile App Development: Native vs Hybrid
Your company needs a mobile app and you want to save money (of course). You want the app live last week, and you’d really like to avoid hiring Android and iOS devs on top of your existing web team.
In light of these considerations, going the hybrid route looks like a pretty good option. Hybrid mobile apps promise to be cheaper and faster to develop, and they’re built with tried and true technologies like Javascript, HTML, and CSS. The hybrid sales pitch can be summarized as “one codebase for multiple platforms”. Hybrid platforms include React Native, PhoneGap, Ionic, Titanium, and others.
Computed Properties vs Functions – Why Does It Matter?
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
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.
Learning from Project Retrospectives
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?”
