How much to build and how much to buy: powering chat and messaging apps freeCodeCamp - Medium

When youre building a chat application of any kindfrom mobile group messaging and multiplayer in-game chat, to customer support and chatbotschoosing the right platforms, frameworks, and protocols can make or break your business.

Thats because deciding whether to build or buy a chat app isnt binary. The days of making a decision to do-it-yourself or buy from a vendor are gone.

The question now is how much do I want to build, and how much do I want to buy?

Between open-source, IaaS, PaaS, SaaS, SDKs, APIs and Microservices, businesses have never had more options for how they want to build their chat products. And the spectrum of choices only continues to widen.

As cloud computing becomes more accessible and affordable, innovative new companies solve specific problems. Devices become more powerful. If businesses want to keep up, they must understand the vendor landscape along with the benefits and challenges of each option along the spectrum.

As a result, there are many mistakes that developers and organizations can make when choosing chat or messaging platforms for their application.

In this post, well discuss a number of different chat application types and look at the different platform options for powering and delivering messaging apps. Well also discuss challenges that can arise from making certain decisions throughout the development cycle, like scalability, time to market, and other differentiators.

Choosing a chat service provider: current landscape

There are a wide variety of options across the build vs. buy spectrum. You have open-source on one end (build) and fully built out (SaaS) solutions on the other (buy). With hundreds of options in between, all with different pros and cons, well seek to give you an idea of the landscape in a simple chart:

Open-source protocols

The furthest on the build side are open-source protocols like WebSockets and HTTP Long Polling. These are simply protocols, which means that you manage everything to make them work. That includes spinning up your back-end infrastructure, maintaining it, building new SDKs to support new devices and languages, and everything else.

These are great for prototyping, building small applications, or getting your hands dirty with the full stack. But most real-time messaging services offer free versions with all the back-end infrastructure included. And youll need to gear up for some serious headaches when its time to scale.

Open-source frameworks

Open-source frameworks are a smidge past pure build, but...

Naomi Thompson Woman of the Present and the Future IN DEFENCE OF YOUTH WORK

Ive got many a reservation about the Awards culture in todays society cue more cries about my continuing slide into miserabilism. However, I did manage a genuine smile at the news that this week Naomi Thompson was the recipient of the Woman of the Future Professions Award. Im not sure about the notion of the future as in the here and now Naomi has contributed significantly to the world of youth work as a youth worker and lecturer, as a writer, her latest book being Young People and Church since 1900: Engagement and Exclusion and, not least from our point of view, as a passionate and committed member of the IDYW steering group.

naomi

The Professions Award recognises women who are making a significant contribution in sectors such as legal, medicine, accounting and education, and who are tipped to reach the top of their field.

The judges described her as an ambitious role model for students, especially with her mixed methods research experience and focus on youth work, religion and crime.

Naomi Thompson said: I was humbled and delighted to win the Women of the Future Award after being short-listed alongside some incredible women. The judges commended my research in many areas and my journey from becoming a young parent at aged 20.

However, the award is a recognition not just of my journey but of the people who have supported me along the way, including the academics and students who suppor...

Do you want to learn more about React? Lets build and then play a game. freeCodeCamp - Medium

When I teach React to beginners, I start by introducing them to the React API. Then I have them build a simple browser game after that. I think this is a good introduction strategy, because a simple game usually has a small state and, in most cases, no data dependencies at all. Learners get to focus entirely on the React API itself. The official React tutorial is a simple Tic-Tac-Toe game, which is an excellent choice.

Building simple game apps beats building abstract (and todo) apps on so many levels. I have always been against the use of abstract foo-bar types of examples, because they lack context and engagement.

Learners need to like what they are building. They need to accomplish something at the end of each phase in their learning journey. They need to make design decisions and see progress on features they can relate to.

Please note that this article is not a beginners tutorial. I will be assuming that you know the basics of React. If you are absolutely new to React, start by writing your first React component and then learn the fundamental concepts of React.

The Target Sum Game: Pick the set of challenge numbers that sum to the target 42 within 10 seconds

I named the game we are going to build in this article The Target Sum. It is a simple one: you start with a random number in the header, the target (42 in the screenshot above), and a list of random challenge numbers below that target (the six numbers in the screenshot above).

Four of the six random numbers used above (8, 5, 13, 16) add up exactly to the target sum of 42. Picking the correct subset of numbers is how you win the game.

Wanna play a few rounds? Click the Start button below:

Were you able to win? I am SO bad at this game.

Now that you know what we are going to build, lets dive right in. Dont worry we will build this game in small increments, one step at a time.

Step #1: initial markup and styles

It is a good idea...

Divergentand other stories livingwithoutschool

We believe in ordinary acts of bravery, in the courage that drives one person to stand up for another.

This quote, from the novel Divergent, highlights why some of what I read is Young Adult fiction.

I read for truth. Truth and hope. Divergent_(book)_by_Veronica_Roth_US_Hardcover_2011

Young adult novels, regardless of genre, reflect the virtue of hope. They are not afraid to honestly portray hope as a human desire. The worlds of YA novels are not tainted by unnervng, unforgiving, unending cyncicism. For, while cynicism, exists, as in Quicksilver by R. J. Anderson, the cynicism of  a girl who is different and who learns to mistrust others, there also exists a parallel of hope . Maybe things can be different. Maybe  two people who care deeply about something bigger than each other,drawn together by a shared commitment to that common ideal or goal can describe both friendship and love.

It is this hope that marks the call to action one encounters in YA fiction. YA fiction has a strong voice. It is often writt...
