The Software Grief Cycle

People pile layers on top of layers, abstractions on top of abstractions, complications on top of complications, crap on top of patches, and patches on top of crap until everything collapses onto itself and the singularity appears.
- Source lost on the Internets

 

After reflecting upon my last Weekend Reader, I came up with some more thoughts about the fact that software is eating the world and the  long-run problems that result from the fact that we create new systems at an ever increasing rate.

Tudor plays with the idea of “Software Environmentalism". This implies that there was a clean environment that gets polluted by software systems. The assumption is, that, as in nature, the environment can only deal with a certain amount of pollution, therefore we must start taking care and according to Tudor's idea:

No system should get away without dedicated tools that help us take it apart and recycle it effectively.

 

Let’s see what Steve Jobs once claimed about software: Eventually it collapses under it’s own weight!

 

Let’s repeat:

"It doesn't matter what you do, eventually it will collapse”.

It's like with humans and death ... it's inevitable. We can prolong our lives by living healthy and modern medicine sometimes allows to keep us alive even when it does not make much sense any more ... but we all are getting old and finally we will die.

So there you have another analogy, actually a full bag of analogies.

Any software will age and finally it will die. Some software will age more gracefully than other software, but they all will die. We have to accept that. This is not an easy insight, there are the five stages of grief (denial, anger, bargaining, depression and finally acceptance). Letting the software die might become painful for everybody involved… especially if you try to deny the fact. Often developers are way ahead of management on the stages of grief:  

 

I would argue that we are still dealing with a very high mortality rate in the software industry today. But we are not dealing with the tragedy of stillborn children or sudden child death. No, in the software industry we mostly deal with monstrous frankensteinian abominations that will not be able to breathe on their own. Still we keep trying to somehow create the perfect monsters ...

Often we are helpless in dealing with dying software. There is also a lot of software that should have died a long time ago, but it was not allowed to. Nowadays there are armies of maintenance developers defibrillating, heart-massaging and mouth-to-mouth breathing thousands of zombie systems all over the world.

Undead code

How can we deal with dead and dying software? Maybe we just have to be more cruel (and more honest) and accept their death. Maybe this enables the rest of the software population to live healthier, maybe even to thrive and prosper… the other important thing here is to get rid of the dead. Make a clean break, don’t keep the dead (or  almost dead) software lying around. Dead or dying software has the tendency to keep you incredibly busy. If you are not cruel, you won’t get rid of it:

 

Different cultures dealt differently with ageing and dying individuals. A well known example is the senilicide in ancient Eskimo culture: Old people that could no longer contribute to the well-beeing of the group were cast out to die in the snow. This certainly was a very cruel way, but it ensured the survival of the group in times of scarcity.
It is a well known fact, that enterprises have big problems finding developers to maintain their legacy systems. Developers often are not motivated to deal with legacy software. The lack of good developers that deal with legacy software, makes maintaining dying systems even more difficult and can accelerate the rotting of that software.
So maybe this is the cruel way in the software development ecosystem: In times of scarcity, developers choose which systems should die by refusing to work on them ...

On the News:

Translation of the Apple-IBM romance

You heard it, Apple and IBM are best friends now. But what does it mean? This funny post translates the press release into something that we can understand:

 Enterprises love hand holding more than fat kids love candy. Apple is going to offer them hand holding through IBM.

 

Reflecting on Software Engineering:

Software Environmentalism

My colleague Tudor is musing about how we can deal with the fact that software systems get larger and larger, and they are being created at an ever increasing rate.

We cannot continue to let systems loose in the wild without any concern for how we will deal with them at a later time.

He proposes:

No system should get away without dedicated tools that help us take it apart and recycle it effectively.

For the profession he concludes:

Software engineering is more about dealing with existing systems as it is about building systems.

 

The Maintenance Developer Myth and The Noble Art of Maintenance Programming

So, software maintenance and dealing with legacy code is only going to increase as software is eating the world. But introducing a chasm between “real” developers and “maintenance” developers is probably not going to help.

 

What are good developers anyway?

Why are we interviewing developers by asking architect questions? Is it really what we need? When we deal with legacy, architecture gets less and less important. Problem solving skills are what really matters ...

 

But software eventually collapses under it’s own weight

(the obligate wisdom from Steve Jobs, which seems fitting at that point)

 

On JavaScript:

This is a interesting course on pluralsight. I am wondering what the alternative would be for the Java ecosystem? I guess I will attend the ELK workshop at ch/open Workshoptage in this regard.

 

Java Script Jabber Episode 106: Protractor with Julie Ralph

A good introduction to end-to-end testing in general and to the Protractor test framework. The episode also contains good discussions about software testing in general and gives insight about testing at Google.

Developers are taking over the world!

Newkingmakers

Everyone involved in software development projects should read the book The New Kingmakers.

The book gives the background why traditional tayloristic approaches are not effective in the knowledge work environments of software projects: Plans and roadmaps are not going to work as long as you don’t get developers intrinsically motivated.

For some reason the book is free on the Kindle.

 

On the same topic:

 

Planning, planning and more planning!

Speaking of motivating developers. In my experience, one of the most demotivating construct in enterprise development is planning. 

BrtAGhlCIAEZa 4

The Agile Manifesto speaks about "Responding to change over following a plan”.

While Scrum is facilitating many Agile principles, the concept of the backlog is often used to re-establish a waterfall-like long-term plan. With the long-term plan comes the justification for controlling and micro-management. Newer methodologies that promise to “scale agile to the enterprise” (like SAFe) even reinforce this tendency for establishing and following a plan (note how the arrows in SAFe all point in one direction?). SAFe is an approach by classical management to re-apply tayloristic approaches that have been questioned by the Agile movement. 

That’s why Water-Scrum-fall is the reality of Agile today.
And that’s why I don’t believe in scaling Agile to the enterprise
That is why we have the Manifesto for Half-Arsed Agile Software Development.

 Ken Schwaber (the inventor of Scrum) puts it like this:

A core premise of agile is that the people doing the work are the people who can best figure out how to do it. The job of management is to do anything to help them do so, not suffocate them with SAFe.

 

Do we really need strict control (which is basically the reason for all that detailed planning)?

Tom De Marco (a pioneer and author in the area of software project management) has an interesting thesis about this in his paper: Software Engineering: An Idea Whose Time Has Come and Gone?

strict control is something that matters a lot on relatively useless projects and much less on useful projects

 

What can developers do: They should choose their work!

So for us developers this boils down to making a choice: What kind of projects do we choose to work on?

Mike Monteiro repeats that in his brilliant presentations: How Designers Destroyed the World

The work we choose to take on defines us!

Conferences

I want to point to two special upcoming local conferences:

SwissJeese - An indie JavaScript conference in my beautiful hometown of Bern (July 26th 2014). I have never been to that conference and unfortunately my talk-submission was not accepted (probably the topic of Nashorn is too enterprisy for the conference :-)). But the program looks very promising and there are still tickets left.

ch/open Workshop Tage - An excellent event with a marvellous collection of interesting topics (September 9-11, 2014). I am attending and also holding workshops at the Workshop Tage for the last 7 years, and each year I am looking forward to the event again.

 

Battle Cry

Speaking of conferences: Philip is calling for an epic battle: Web vs Native on mobile devices - let the strongest prevail!
(actually, according to the rules of Philip it would be the quickest, not the strongest ... maybe Philip should look again at what happened to Oberyn Martell?)

 

On JavaScript

The obligate Gartner prediction:

Through 2014, improved JavaScript performance will begin to push HTML5 and the browser as a mainstream enterprise application development environment.


ThoughtWorks Technology Radar chimes in
:

The ecosystem around JavaScript as a serious application platform continues to evolve. 


Prezi writes about their experience from migrating from Flash to JavaScript … and why it took so long:

Large JavaScript codebases are hard.


Stackoverflow explains the difference between JavaScript and Java
:

Java and Javascript are similar like Car and Carpet are similar.

One is essentially a toy, designed for writing small pieces of code, and traditionally used and abused by inexperienced programmers. The other is a scripting language for web browsers.

  

ch/open Workshop Days: Great Program as Always!

Ch open logo

The program of this year's ch/open Workshop Days has been published.

As every year, it is a great program with many interesting sessions. This year even with 5 parallel tracks. It’s going to be a hard for me to decide which sessions to attend...

On Wednesday I will hold my “JavaScript Survival-Bootcamp”. The session was a big success last year (fully booked twice), and I intend to repeat that.

Unfortunately Marc will not be able to hold the workshop with me this year.

AngularJS: Illustrating Model-View-Whatever

There are already many attempts at explaining and illustrating the concepts for structuring an Application in Angular.

Actually Angular was declared a MVW (Model-View-Whatever) Framework to avoid further philosophical discussions.

Still, for my current Angular workshops I created my own visual interpretation:

NG MVC 001

What do you think?

Lets start with some Java bashing:

Java Web development is broken!

Rather focusing on provocation than facts, but still worth watching:

Conquering the wicked kingdom of Java with a NodeJS Trojan horse - Espen Dall√łkken from Booster conference on Vimeo.


But Reg Braithwaite chimes in:

JSJ Community Dynamics with Reginald Braithwaite

Java is playing defense while JavaScript is still playing offense. [...] Java 8 is all about protecting the existing user base. Not about gaining new users.

And not only the JavaScript community is attacking Java:


But let's turn our attention to more relevant topics than petty language wars:  


The largest cost in business is unnecessary complexity.

... and automation only hides complexity. We should remember this when we indulge in continuous integration, continuous delivery and devops.

 

There is not only technical complexity, so it's always good to revisit some articles:

Bug statistics are a waste of time:

Defect tracking tools are placebo, giving people a warm and cosy feeling that they have done something by throwing a digital coin into a fountain of wishes, while hoping for better software.


Beyond Story Cards: Agile Requirements Collaboration

Story card hell is when you have 300 story cards and you have to keep track of them all. [...] Every customer I've ever worked with wanted to put story cards in a database. That misses the point of story cards. If you're worried about losing story cards, you're doing too much with them.


Speaking about Agile:

Agile is not Dead (But Some Organizations Might Be Soon)

Changing the use of one word is not going to address a fundamental problem in organizations.

How convenient that Agile is no dead, it would be cumbersome to scale something that is dead:


This actually does make a sensible impressions, why all the critics?

So its time for another round of certifications? SPC sounds great... SAFe Program Consultant (SPC) Certification - Zurich Aug 11-14, 2014


... but I think I had enough of Agile certifications. Back to language bashing:


... even better let's start bashing the programming community in general:


A lot of what is going on today in software methodology and practices is pseudoscience!


If you are not interested in DHH's childhood, then skip to minute 11. But there it starts: He is amazing, comparing Computer Science with Diet Schemes.
Most information system development has very little to do with the science part of computer science.

Is this just a case of The DHH Problem?

I am teaching JavaScript, are you interested?

Jjs

Last month I was teaching my workshop “Professional JavaScript for Java Developers” at Puzzle ITC and at Glue Software Engineering AG in Bern and both workshops were received very well.

At the same time I am currently teaching a block of 8 days at the University of Applied Science in Bern in the new CAS “Multiplatform Development with HTML5” about the topics JavaScript, JavaScript Frameworks and HTML5.

JavaScript has a lot of momentum right now. Especially corporate environments are currently embracing JavaScript (together with HTML5) as a serious option for developing and delivering enterprise applications.

Traditionally professional development teams in corporate environments were not exposed to JavaScript, even when they were creating web applications. Therefore in many teams there is a reluctance to accept JavaScript as a viable platform.

My workshop shows the current state of the JavaScript ecosystem (Frameworks, Libraries, Tools) and touches all the aspects of professional development in the JavaScript ecosystem. The workshop is especially addressing traditional OO programmers with an enterprise background. Attendees learn how to realise the concepts and best practices they know and love from their traditional platforms (Java, .NET …) on the JavaScript platform. This ranges from constructs for encapsulation and modularisation over debugging and unit testing to build automation and dependency management. 

The main modules of the workshop are the following:

  • Introduction to JavaScript and the JavaScript Ecosystem
  • JavaScript: The Language
  • Introduction to jQuery
  • The JavaScript Development Toolchain
  • Client-Side MVC with AngularJS
  • Communication with the Backend

The workshop consists of many demos and hands-on exercises. The minimal duration is one full day. For a deeper dive into certain modules the workshop can be extended to two or three days.

Please contact me at info@jonasbandi.net if you are interested in a JavaScript workshop for your development team. I am teaching the workshop in German or English.
