Today’s post is short essay concerning the value of development led quality. There are no code examples or short tips for things in this post. I hope you enjoy.
Today’s post will cover a couple different approaches to transfering techinical knowledge of a software system between individuals or teams. There are often transfers of ownership as a software product progresses from conception to feature development to ongoing maintainence. Effective knowledge transfers between owning individuals or teams help to ensure that ongoing development of a product is not totally stalled whenever ownership chagnes
Apache CouchDB 2.0 was recently released and has some compelling features for those looking for clustered document oriented databases. In today’s post I want to share a few of things that I’ve learned on how to use CouchDB’s new features and how to avoid some new user mistakes that we made along the way.
Today’s post will go over some of the reasons for why I switched my personal blog back to being generated via a static generation tool from Wordpress. I have previously written about not using static content tools , we’ll look at some of the things that have changed in the last couple years with regard to complaints I had in 2014.
I enjoy running my own blog at codinginthetrenches.com because I am a technologist that likes to write. Unfortunately, sometimes my interests as a technologist get the better of my interests as a writer. This last week my competitive interests resulted in my blog being visually broken for several days. Furthermore, the competition has resulted in a few select articles being mis-formatted and visually broken for much longer than a week.
Today’s post is about what I’ll be doing to avoid these problems and how they can apply to your own writing platform.
We often think about best practices while developing software. Sometimes it is also instructive to contemplate what not to do when writing software. Today’s post covers some logic in AngularJS services which should be avoided save for rare exceptions.
Developing new software involves resolving a frequently unknown quantity of problems of unknown complexity. Even when working on existing projects, new initiatives and features can contain a unknown total amount of complexity. While being appealing modern product management methods, scrum and other related methodologies focus on relative estimation which has limitations when starting brand new work. Today’s post looks at some of our limitations when it comes to estimation and what is implied by those limits.
Networks are unreliable. Put more precisely, TCP networking can experience many different types of failures with resulting loss of connectivity. Do not let the linked post’s title fool you, it goes on to list a number of real-world computer networking failures. HTTP is a great way to communicate over the public internet, where failures may occur at any time, because the protocol itself is stateless and does not rely on a persistent connection. HTML5 WebSockets, however, do use a persistent TCP connection. A connection that can cut or closed without warning. Today’s post is a short commentary on adding error handlers and heartbeat messaging to WebSocket clients and servers.
It is a good practice to add logging capabilities to applications as they are built. There are a lot of good tutorials on how to setup logging within various applications and software frameworks. It is also instructive to discuss why something is a good practice since understanding why can lead to new insight in how, when, and where to apply said ‘thing.’ The point of today’s post is to discuss some scenarios for why application logging is important. This post will be mostly non-technical because the how of logging can be learned with some decent web searches and there is already a wealth of information on logging software on the web.
Round robin DNS records are a technique for distributing load across public facing web servers. As an experiment we tried using them in order to distribute load inside of a cluster. We found this approach didn’t work. In this post I’ll discuss round robin load balancing, how it works at a high level, what we did with DNS, why it didn’t work, and what can be done instead.
