Digging deeper into CMS requirements (#5: The last one)

This is the fifth post about digging deeper into content management requirements. See also

I know I was going to rant about agile development and Scrum soon, but what the heck; I'm inspired! Today I'm gonna finish off the CMS Requirements thread and describe THE most important requirement of all. And hopefully on sunday I will explain how all these requirements are interconnected by two key principles:
  • Open Source
  • Open Standards
Now writing about the other requirements has been quite a booring affair. They have just been sort of basic explanations that can lead up to sunday's post.

However
, this requirement is no ordinairy rabbit! It's not measurable, you can't actually describe it, and it's darn hard to implement! It is a utopical state software, an *ility of the highest degree.

2 years of CMS research, coffee drinking, chocolate-chip cookie eating and hard thinking made me believe that the most important requirement of a content management system is...

Extensibility

There ye have it. The number one thing that comes back to kick me in the head after having delivered a top-notch user friendly CMS is this:

Customer: "Oh, the new homepage looks great. Can we put our boat/customer/shop/weather/blog/forum/registry/directory/services up there?"

Extensibility. The quality of software that allows you to extend basic functionality with new custom tailored stuff. The last 20 or 10% that you need to get the perfect CMS.

There are many factors that multiply into this one. Stuff like plugins, portlets, parts and widgets are implementations where people have tried to put extensions. Modularity is factor, as is simplicity in the code base.

But the most common factor in extensibility is openness and agreements. Standards.

If I can understand my CMS, I know how to extend it.

This is actually a quality in most software! In fact lower level software like programming languages and operating systems are based on the very possibility of extension.

But we are talking about CMS'es here. And they deal with content. Content is historically not a very extensible format. You define your SQL schema or file-format, and you stick to it. Once you start using it you can forget anything about extending the use of your content, translating it, exporting it in a usable format, or importing other kinds of content. At least not for anything less than a fortune in developer costs. There are no content standards (well, some are appearing, like RDF and JCR).

If we do settle on a content standard that offers us the possibility to extend the use of our content we can start developing CMS'es that can realise the potential of extensible content.

Yes, you can extend your CMS for user registration and profile editing. You can expose your content as blog-posts. You can create articles of content that are either news, weather-forecasts, image-libraries, data-sheets, documents, and so on and so forth. You just need the content format to do so.

Let us stop hammering content into relational databases! Stop pushing maps and references into flat tables. Stop creating portlets, widgets, plugins and templates just to display your table-relational data a certain way.

Instead store your content in a generic way, and expose it a generic way. These are the principles the Internet is built around; standard storage format and standard transport format. We seem to have come a long way on the transport format, but are still way behind on the storage format because of greedy, properitary vendors that have not sooner come together to standardize content storage.

Well, I think that rant was a bit of a head start on sunday's post, but I'll hold on to the rest of it for now. In the future I'm gonna slide in on a track which focuses more on the field of open source and open standards, and let me add that I haven't been reading up on my Open Source Journal recently, so if I am obviously repeating any ideas that others have published, let me know.

Need to write invitations for the upcoming St. Patrick's day party :)

Encrypting and Decrypting with Spring

I was recently working with protecting some sensitive data in a typical Java application with a database underneath. We convert the data on its way out of the application using Spring Security Crypto Utilities. It "was decided" that we'd be doing AES with a key-length of 256, and this just happens to be the kind of encryption Spring crypto does out of the box. Sweet!

The big aber is that whatever JRE is running the application has to be patched with Oracle's JCE in order to do 256 bits. It's a fascinating story, the short version being that U.S. companies are restricted from exporting various encryption algorithms to certain countries, and some countries are restricted from importing them.

Once I had patched my JRE with the JCE, I found it fascinating how straight forward it was to encrypt and decrypt using the Spring Encryptors. So just for fun at the weekend, I threw together a little desktop app that will encrypt and decrypt stuff for the given password and sa…

Managing dot-files with vcsh and myrepos

Say I want to get my dot-files out on a new computer. Here's what I do:

# install vcsh & myrepos via apt/brew/etc
vcsh clone https://github.com/tfnico/config-mr.git mr
mr update

Done! All dot-files are ready to use and in place. No deploy command, no linking up symlinks to the files. No checking/out in my entire home directory as a Git repository. Yet, all my dot-files are neatly kept in fine-grained repositories, and any changes I make are immediately ready to be committed:

config-atom.git
    -> ~/.atom/*

config-mr.git
    -> ~/.mrconfig
    -> ~/.config/mr/*

config-tmuxinator.git  
    -> ~/.tmuxinator/*

config-vim.git
    -> ~/.vimrc
    -> ~/.vim/*

config-bin.git   
    -> ~/bin/*

config-git.git          
    -> ~/.gitconfig

config-tmux.git  
    -> ~/.tmux.conf    

config-zsh.git
    -> ~/.zshrc

How can this be? The key here is to use vcsh to keep track of your dot-files, and its partner myrepos/mr for operating on many repositories at the same time.

Always use git-svn with --prefix

TLDR: I've recently been forced back into using git-svn, and while I was at it, I noticed that git-svn generally behaves a lot better when it is initialized using the --prefix option.

Frankly, I can't see any reason why you would ever want to use git-svn without --prefix. It even added some major simplifications to my old git-svn mirror setup.

Update: Some of the advantages of this solution will disappear in newer versions of Git.

For example, make a standard-layout svn clone:

$ git svn clone -s https://svn.company.com/repos/project-foo/

You'll get this .git/config:

[svn-remote "svn"]
        url = https://svn.company.com/repos/
        fetch = project-foo/trunk:refs/remotes/trunk
        branches = project-foo/branches/*:refs/remotes/*
        tags = project-foo/tags/*:refs/remotes/tags/*

And the remote branches looks like this (git branch -a):
    remotes/trunk
    remotes/feat-bar

(Compared to regular remote branches, they look very odd because there is no remote name i…

Joining eyeo: A Year in Review

It's been well over a year since I joined eyeo. And 'tis the season for yearly reviews, so...

It's been pretty wild. So many times I thought "this stuff really deserves a bloggin", but then it was too inviting to grab onto the next thing and get that rolling.

Instead of taking a deep dive into some topic already, I want to scan through that year in review and think for myself, what were the big things, the important things, the things I achieved, and the things I learned. And then later on, if I ever get around to it, grab one of these topics and elaborate in a dedicated blog-post. Like a bucket-list of the blog posts that I should have written. Here goes:
How given no other structures, silos will grow by themselves This was my initial shock after joining the company. Only a few years after taking off as a startup, the hedges began growing, seemingly almost by themselves, and against the will of the founders. I've worked in silos, and in companies without the…

Automating Computer Setup with Boxen

I just finished setting up a new laptop at work, and in doing so I revamped my personal computer automation quite a bit. I set up Boxen for installing software, and I improved my handling of dot-files using vcsh, which I'll cover in the next blog-post after this one.

Since it's a Mac, it doesn't come with any reasonable package manager built in. A lot of people get along with a combination of homebrew or MacPorts plus manual installs, but this time I took it a step further and decided to install all the "desktop" tools like VLC and Spotify using GitHub's Boxen:

  include vlc
  include cyberduck
  include pgadmin3
  include spotify
  include jumpcut
  include googledrive
  include virtualbox

If the above excerpt looks like Puppet to you, it's because it is. The nice thing about this is that I can apply the same puppet scripts on my Ubuntu machines as well. Boxen is Mac-specific, Puppet is not.

It was a little weird to get started with Boxen, as you're offered…
