Learning from Kent Beck

Here's a great post that I'm sure others have seen and posted. Three guys had the opportunity to do some prototyping with Kent Beck, the creator of TDD and thankfully, one of them, documented it. I haven't ready Kent's implementation patterns book

The entire post is very long and detailed but I wanted to post some key takeaways as they apply to pretty much any project.

Make your code readable.  "Code is primarily means of communication."



KISS. "Apply simplicity at all levels."


Flexibility "Programs should be flexible in the ways they change, they should make common changes easy or at least easier. "

Approaches to coding. When thinking about Agile, people start creating sprints of 2 weeks or less. When prototyping, an even quicker sprint came up - "what would be the demo we would like to show at the end of the day. And his next question was what test to write."

Write tests that test needed functionality, at a high or unit level. "Speculating about failure points can be just as wasteful as speculating about design."

Write Code in the Test, then Refactor. (I know, think about it. I actually started doing this when I was first learning TDD and thought - "is this really what I'm supposed to do?") " Instead of thinking about how it should be organized (what classes to create, where to put them, whether to use a factory class or a factory method), why not initially write the code directly in the test method? You can always factor out the code later."

Focus on one thing at the given time. " If you notice along the way something else that needs to be done – giving a method a better name, removing a dead code, fixing an unrelated bug – don’t do it, put it on a task list and do it later. "

Symmetry in Code. "Symmetry in code is where the same idea is expressed the same way everywhere it appears in the code."


The entire post is a great read.

Well, that explains CodePlex...

In a move that will be sure to anger open source (or rather anti-paid software, anti-Microsoft open source)  zealots, Microsoft is planning to buy GitHub.

A year ago, I mused about why Microsoft would shut down CodePlex and how the world needs competing source code repositories to be strong. I'm not the only one per this Slashdot article :
"...people have warned about GitHub becoming as large as it did as problematic because it concentrates too much of the power to make or break the open source world in a single entity, moreso because there were valid questions about GitHubs financial viability...." - Jacques Mattheij

I will be interested in seeing this play out - whether developers jump ship or not. Have all the efforts Microsoft has made in pushing towards open source be seen as genuine or will all the zealots jump ship or maybe even attack?

Microsoft's comment about why they shut down CodePlex referred to how spammers were using CodePlex. Well, GitHub has its own …

FoxInCloud Stats

FoxInCloud sent this link a while back about their statistics regarding visits to their site:

http://foxincloud.com/blog/2017/12/27/VFP-community-lessons-from-foxincloud-site.html



What's interesting here is the breakdown of people. Yes, I think it's understandable that the Fox community is getting older.

Another factor is the growth of the mobile and web environments taking over development. These environments really do push people towards the newer non-SQL or free SQL/hosted environments but more towards hosted storage options like Amazon and Google. A tool like FoxInCloud that helps MOVE existing applications to the cloud inherently competes with those environments.

But FoxInCloud also allows developers to extend their application further by giving them a starting point using Javascript and the basic CSS (such as Bootstrap). If you're not rebuilding your application from scratch, it's certainly a great step forward.

Attending Southwest Fox 2019 could change your life - Find out how

Southwest Fox is coming up in October and as I do every year, I spoke with the organizers Rick, Doug and Tamar on the FoxShow.

Deadlines for Southwest Fox:
Super-saver price (before July 1): $695
Early-bird price (before August 1): $770
Regular price (August 1 and later): $820
This year, I took a different approach with separate shows for each organizer but the main message is still the same : July 1st is their Go/No-Go date.

Conferences don't talk about this very often. I don't think developers really question if Apple will hold their WWDC in June or Microsoft will hold their Build conference - but that's because those conferences are vendor-led.

Southwest Fox is a community-driven conference - it's not driven by a company with an agenda. Listen to the interviews and you can hear how important each of the organizers feel the live connection between speakers and among attendees.
