Book Review: Practices of an Agile Developer

Software development is widely known as having the largest gap of any discipline between the best known practices and the actual practices utilized in the field. The most depressing part of that statement is how inaccurate the qualifier of "widely known" probably is, because if the gap was as well and widely known as it should be, the gap would be shrinking much faster than it is. Is the gap even shrinking at all?

One of the things on the good end of this gap is the collective practices known as Agile Development. The creation of software is fluid and must be adaptable at a moments notice, defined as it is created, and grown rather than built, says the mantras of the agile development proponents. They contrast to the traditional and aging mentality of designing everything before writing anything, following a walled path to the goal, and building monoliths of code. The differences between the old side and the new side are great, and this is the gap we need to wade across to solve the ever growing problem of software quality nightmares.

Practices of an Agile Developer does a fantastic job of taking you across that gap, step by step, and bestowing the benefits of engineering yoga. First to last page is packed with excellent tips, techniques, proven methodologies, and stories of horror and salvation by the blessing of a better way to create software.

There is a lot in this book that I was not aware of and a lot I was well aware of, and even some things that I tried actively to practice. I didn't know how much of the practices I used were part of the "agile" moniker, but they worked. Because I knew a lot of my favorite practices had something to do with this strange movement I kept getting glimpses of, I picked up a copy of the book at Borders and decided to fill in the blanks between what I knew.

I found most of the book to be a reinforcement of things, but there was a sizable number of completely new thoughts to ponder. Iterative development, unit testing, small and non-breaking changes, and utilizing the tools like bug trackers and source control, were all related to my real world experience, which made them even more mentally valid.

For anyone who can program and wants to become a better developer, this is a great volume to pick up. At 178 pages before the appendixes, you can run through and absorb the content quickly and begin putting it to good use. I've seen improvement in my own work, and it takes will power to put the things you learn to common use by yourself, but its worth the effort. If you have heard of agile development, learned some things about it, or know nothing at all of the issues, you will find this a good read if you want to be better at what we love to do: create good software.

Why I Switched From Git to Microsoft OneDrive

I made the unexpected move with a string of recent projects to drop Git to sync between my different computers in favor of OneDrive, the file sync offering from Microsoft. Its like Dropbox, but "enterprise."

Feeling a little ashamed at what I previously would have scoffed at should I hear of it from another developer, I felt a little write up of the why and the experience could be a good idea. Now, I should emphasize that I'm not dropping Git for all my projects, just specific kinds of projects. I've been making this change in habit for projects that are just for me, not shared with anyone else. It has been especially helpful in projects I work on sporadically. More on why a little later.

So, what drove me away from Git, exactly?

On the smallest projects, like game jam hacks, I just wanted to code. I didn't want to think about revisions and commit messages. I didn't need branching or merges. I didn't even need to rollback to another version, ever. I just …

Respect and Code Reviews

Code Reviews in a development team only function best, or possible at all, when everyone approaches them with respect. That’s something I’ve usually taken for granted because I’ve had the opportunity to work with amazing developers who shine not just in their technical skills but in their interpersonal skills on a team. That isn’t always the case, so I’m going to put into words something that often exists just in assumptions.
You have to respect your code. This is first only because the nature and intent of code reviews are to safeguard the quality of your code, so even having code reviews demonstrates a baseline of respect for that code. But, maybe not everyone on the team has the same level of respect or entered a team with existing review traditions that they aren’t acquainted with.
There can be culture shock when you enter a team that’s really heavy on code reviews, but also if you enter a team or interact with a colleague who doesn’t share that level of respect for the process or…

CARDIAC: The Cardboard Computer

I am just so excited about this.


CARDIAC. The Cardboard Computer. How cool is that? This piece of history is amazing and better than that: it is extremely accessible. This fantastic design was built in 1969 by David Hagelbarger at Bell Labs to explain what computers were to those who would otherwise have no exposure to them. Miraculously, the CARDIAC (CARDboard Interactive Aid to Computation) was able to actually function as a slow and rudimentary computer. 
One of the most fascinating aspects of this gem is that at the time of its publication the scope it was able to demonstrate was actually useful in explaining what a computer was. Could you imagine trying to explain computers today with anything close to the CARDIAC?

It had 100 memory locations and only ten instructions. The memory held signed 3-digit numbers (-999 through 999) and instructions could be encoded such that the first digit was the instruction and the second two digits were the address of memory to operate on. The only re…
