How to make a software developer happy ?

Leave your comfort zone

To be or not to be (happy), that’s the question. In this article, I expose some thoughts about what could make a software developer happy in his work. I wrote this article with several targeted audience in mind : Junior developers, Senior Techleads and H&R resources.

I have tried Vue.js and I love it

Vue.js Framework

I have tried Vue.js and just love it.

Some weeks ago, I started a new project for which, I have to build an internet website.


After spending really long hours on internet, browsing, collecting every possible testimonials and advices and comparing them to my first impressions, I decided to start with an hybrid / multiple page site.

(if you are interested by the reasons, it will be the subject of another post).

An hybrid /multiple page site is a website where the content is rendered both from server side and client side at the opposition of single page application (SPA) full client side and a classical server side site(PHP..) Since I want to use the power of modern Js Frameworks as double binding, refreshing, Ajax widgets, Es2016, reactive programming and somewhat control which pages needs to be reloaded, I had to make a choice.

The list of choice is somewhat limited if keep only the 5 most popular ones. (yes I am resolutely not a pioneer of the JavaScript Jungle)

The framework selection

I made the following list :

  • Angular 2+ (they are increasing the major version number for each patch ūüėÖ)
  • React.js
  • AngularJS
  • Ember. Js
  • Vue.js
  • JQuery (it is a joke)

Selection criteria

I defined some selection criteria besides the popularity :

No code bloat : specifically to JavaScript, the syntax and the missing OOP native programming have been producing many frameworks with dumb syntax without any semantical and often syntaxical meaning. To overcome the limitations, many frameworks are using syntax sugar, making them a nightmare to memorize. The most ridiculous is the attempt to stick on these syntaxical blobs, some pseudo theorical terms.

A good framework should offer different levels of usages from the straightforward approach to build quickly and easily a website with the common use cases to the low-level approach where the experimented developer is able to tune the required details. What has been done in Laravel, Spring framework or Symphony are good samples.

Symphony framework is known as a huge galaxy. Many components, industry quality grade, but an overwhelming complexity if you start head on.

Therefore they have created a micro‚Ää‚ÄĒ‚Ääframework called Silex to bootstrap an PHP application without the nasty details and it is deadly simple. If you want more complex things, the components behind Silex are the Symphony ones.

For a web framework, always study how do they handle forms. Especially a basic post form. It takes five minutes in plain HTML to build an (unsecured) form. How long does it take with this framework?

The same thing works for **Spring* and Spring boot.

The framework must have a business friendly licence. No doubt, no legal restriction for the future company. (by the way do you know you cannot build weapons software in Java, please stick to the line…)

An extensible / plug-ins architecture. I believe the success of a framework resides in the possibility to enable the necessary functionalities (aka feature toggling) during your project. Authentication, reactive programming, lazy loading, modularity.

The evaluation (aka trolling section)

Based on these selection criteria, here is my evaluation.

Disclaimer: I have a highly respect for the guys who wrote these frameworks and I do not doubt of their outstanding skills. AngularJS

I have experienced projects with AngularJS and I renounced since it is a deprecated technology. Too much code bloat, slow (I should rather say hard-to-tune) and all efforts are concentrated on the new Angular framework. Also, I think I could have a problem with my use case and disabling the AngularJS router.

Angular 2

Angular 2: I have received a training in January and wrote several prototypes since. I have been a huge fan of typescript, angular-cli. I was happy and thinking, they took the best ideas from the other frameworks and build a big melting pot.

Angular : melting pot

In Angular, you will find web components, uses template a la React.js, you have opt-in double binding, directives, modular architecture, lazy loading and so on and so on. But I progressively hate Angular for many details, slowing me down in my developments.

I really dislike their API and concepts to build forms. You have two choices, a template form design and programmatic form design. The first one is almost useless and the second one is deadly cumbersome.

In Angular, they decided to kill HTML and recreate it. How? Case-sensitive attributes and non HTML attributes. You cannot use your normal code editor on it. Beautifier tools not works or partially works. And worse of all, they conceive this awful syntax based on brackets, parens, Well, I think their are huge practitioners of the Brainfuck language.

Brainfuck language

Brainfuck language

The last issue I encountered is with their wish to produce an industrial, scalable (in the sense if I put more developers on my project, I maintain a stable learning and complexity curve). Yes, they provide dependency injection, IOC. But it really increases the learning curve.


I really wanted to start with React.js. As far I have studied it, the framework seems full of promises, with some nice pluggable functionalities.

However at the time I began to use it, I received a lot of news. The concern is about the React.js license, the Facebook license (link1, link2, link3).

Since there is a threat for the future business (everything can be considered as a social network after all), I have rejected it.


I have never tried Ember.js. Based in my readings, the framework is definitely worth of attention to build SPA applications but not for my use case. Note : during the writing of this post, I felt on that link, confirming that maybe I was wrong about ember.js


On Twitter, I am receiving a lot of feedback from happy users of Vue.js and I decided to give a try.

The syntax seems deadly simple.

Here is the brief of my experience :

I did not use vue-cli, I had to create my own packaging to adapt Vue.js to multipage architecture.

Code bloat: the Vue.js framework is really simple and the documentation quite good. The documentation for the plug-in vue-loader is quite good but I really hate the webpack syntax to enable it (rant..)

Learning curve: I did not try the most hard-core functionalities of Vue.js, though I am using vue-loader, a different template renderer (pug), transitions, a little bit components and lazy loading.

My biggest difficulty have been to maintain my js bundle as low as possible by producing chunks.

The second issue has been to understand why creating a view was creating an App and my component below using the render() function. However I think that Vue.js is easier than Angular. 2.

As in the previous example, the syntax is quite straightforward, no need to learn complex concepts to begin with.

The framework is also compatible with Typescript and the logic behind is quite simple.

Vue.js can be extended with several plug-ins and functionalities. I did not try all of them and the fact you are enabling them manually is comforting me in my approach.

Vue.js is not enforcing a particular programming paradigm(IOC, interfaces, Reactive programming, or. RxJS).

The only reproach I could formulate is a little fear about the Vue.js ecosystem. Please integrate existing libraries rather trying to recreate or mimic ReactJS libraries.

In conclusion, both of these frameworks are legitimate and have their lot of practitioners, and I don’t blame it. Vue.js has been my choice and I do not regret it, yet, since it has made my project easy, fun and effective.

I will try to provide more feedback in the following weeks especially on form editing, unkt testing and E2E testing.

Thanks for your attention


How migrate from JBoss 5 to 7

This article is part of my working notes on the subject of “How to migrate Web applications running on JBoss AS 5 to the version 7”.

JBoss Application Server – Wildfly

I will go straight to the details though here is some lines about JBoss Server.

From Wikipedia : JBoss Application Server(Now called Wildfly) is an application server authored by JBoss, now developed by Red Hat. WildFly is written in Java, and implements the Java Platform, Enterprise Edition (Java EE) specification. It runs on multiple platforms.

On 20 November 2014, JBoss Application Server was renamed Wildfly.

The product history according Wikipedia is :

  • 5.1 Release 23 May 2009
  • 7.0[10] Release 12 July 2011
  • 7.1 Release February 2012
  • 10.1.0 Release August 2016[20]

The JBoss AS community project has been renamed to the WildFly community project wildfly.org

According this JBoss 5 to 7 in 11 steps, the benefits are :

Processing time decreased by 25% without any code change. Development speed increased in my opinion (it is really hard to measure it) by 50% and we are much more productive (faster server restarts). Memory footprint lowered from 1GB to 512MB. Finally automatic application redeployment finally works! However there is always a price to pay ‚Äď the migration took us 4 weeks (2 sprints).

Thanks to the presentation from Roberto Cortez, we have a clear picture of the migration.

The checklist

Prepare the checklist

When the PAAS or the Web application server have to be upgraded, several regressions may happen. The team has to pay attention to :

  • Server functionalities and integration : Performance, Security, Logging, Monitoring
  • Server configuration
  • Server deployment configuration
  • Application deployment configuration
  • Server API regressions
  • Application regressions
  • Training and risk management

Server functionalities and integration : between the versions, some functionalities and integrations provided by the server may have evolved, be fixed or simply disappeared.

Server configuration : The way the server has been configured, using scripts, GUI, may have changed, forcing the team to change their configuration files and finding the corresponding new way of doing it.

Server deployment configuration : Your deployment model configuration may have to be upgraded : single node, clustered mode, disaster recovery, high availability, reverse-proxying may behave differently in the new versions.

Application deployment configuration : the way to deploy your web applications may have changed in the new versions (GUI mode to script mode…)

Server API Regressions : usually Web Application servers are implementing a specific JEE API version, Servlet API and so on. These API may have changed causing regressions in your applications.

Application regressions : JBoss is including many components extending the JEE with BPM, Persistence, implementation. It is really important to track your dependencies (using Tattletale or mvn dependencies:tree) and interview your team about possible hacks and fixes to overcome the limits of JEE 5. This kind of workaround is difficult to migrate.

Training and risk management : This kind of migration contains its part of risks and changes. Both can create frictions inside your team of between the IT Team and your Dev teams. To ease the migration, don’t forget to dedicate some time to your teams into training to learn the new features of JAS 7. You will also have to adapt your project management to freeze for a while the features until the migration has been done.

Global checklist

This section is providing a checklist to help developers and managers to evaluate the migration risk of their applications.

 Common issues

Here is a list of common issues during the migration of applications with JBOSS AS.

4.2. Debug Migration Issues 4.2.1. Debug and Resolve Migration Issues 4.2.2. Debug and Resolve ClassNotFoundExceptions and NoClassDefFoundErrors 4.2.3. Find the JBoss Module Dependency 4.2.4. Find the JAR in the Previous Install 4.2.5. Debug and Resolve ClassCastExceptions 4.2.6. Debug and Resolve DuplicateServiceExceptions 4.2.7. Debug and Resolve JBoss Seam Debug Page Errors

  • There is a deadlock when using EJB remoting over SSL. This deadlock is present even in EAP 6.2. We’re now at the point when we have quite a patch set of features backported from WildFly to AS 7.
  • JMS : JBoss Messaging server has been deprecated and the compatibility with a JBOSS AS 5 server is really tough to maintain. Some solutions exists as explained below in the article.

 What is changing ?

Here is a summary of the evolutions between the JBoss AS version 5 and the version 6.

 JBOSS AS 6 changes

Here is the compiled list of modifications including the minor version fixes.

  • [Server functionality, Server API, Application regressions] Module based class loading

In JBoss Enterprise Application Platform 5, the class loading architecture was hierarchical. In JBoss Enterprise Application Platform 6, class loading is based on JBoss Modules. This offers true application isolation, hides server implementation classes, and only loads the classes your application needs. Class loading is concurrent for better performance. Applications written for JBoss Enterprise Application Platform 5 must be modified to specify module dependencies and in some cases, repackage archives.

  • [Server functionality, Server deployment configuration] Domain Management : In JBoss Enterprise Application Platform 6, the server can be run as a standalone server or in a managed domain.
  • [Application Deployment] Deployment Configuration : Standalone Servers and Managed Domains : Boss Enterprise Application Platform 5 used profile based deployment configuration. These profiles were located in the EAP_HOME/server/ directory. Applications often contained multiple configuration files for security, database, resource adapter, and other configurations. In JBoss Enterprise Application Platform 6, deployment configuration is done using one file. JBoss Enterprise Application Platform 5 configuration files must be migrated to the new single configuration file.
  • [Server functionality, Application deployment configuration] Ordering of deployments : Application Platform 5 applications that consist of multiple modules deployed as EARs and use legacy JNDI lookups instead of CDI injection or resource-ref entries may require configuration changes.
  • [Server functionality, Application deployment configuration] Directory Structure and Scripts : As previously mentioned, JBoss Enterprise Application Platform 6 no longer uses profile based deployment configuration, so there is no EAP_HOME/server/ directory.
  • [Server application, Application deployment configuration, Application regression JNDI Lookups JBoss Enterprise Application Platform 6 now uses standardized portable JNDI namespaces.
  • [Server functionality, Server configuration, Application configuration, Application code] : Changing logging dependencies
  • [Server API, Application configuration regressions] Resource adapter configuration : In previous versions of the application server, the resource adapter configuration was defined in a file with a suffix of *-ds.xml. In JBoss Enterprise Application Platform 6, a resource adapter is configured in the server configuration file.
  • [Server libraries] Technologies upgrade : JDK 6, JSF 2, Bean Validation (JSR-303), CDI, EJB 3 (1.1.13)
  • Include mod_cluster

  • New RMI Framework : Remote 3
  • VFS Library update
  • [Server functionalities] new server functionalities : Mod_cluster, JBoss Embedded AS
  • [Application deployment] The legacy pooled invoker has been removed. Applications using the pooled invoker should switch to the JBoss Remoting-based unified invoker, which has been the default detached invoker since 4.2.

 JBOSS AS Release 7

Here is the compiled list of modifications including the minor version fixes.

  • [Server functionality, Application regressions] Security improvement

Unlike previous releases, with AS 7.1, remote access requires secure authentication by default. This includes both managment (native, jmx, etc) and various remote application protocols (ejb, jndi, jms, etc); Added SSL support for the Remoting interfaces.

  • [Application configuration deployment] Management API improvements : All configuration attributes are updatable via the CLI. Direct edits to the XML are not necessary.

How to migrate : plan and tasks

  • JDBC configuration
  • Classpath references
  • Global Modules Reference
  • JMS migration :

According link, we thought it would be really hard to connect with JMS server based on JBoss 5. It turned out that you have 2 options and both work fine:

  • Start HornetQ server on your own instance and create a bridge to JBoss 5 instance
  • Uses a JMS Bridge to move the existing messages
  • Use Generic JMS adapter: https://github.com/jms-ra/generic-jms-ra

 Application packaging and configuration

  • Repackaging Dependencies and fix the EAR Layout: link
  • Install and configure the JDBC Driver link
  • Update the Resource Adapter Configuration
  • Configure the datasource for Hibernate and JPA : If your application uses JPA and currently bundles the Hibernate JARs, you may want to use the Hibernate that is included with JBoss Enterprise Application Platform 6.

In WildFly 8, a resource adapter is configured in the server configuration file. If you are running in domain mode, the configuration file is the domain/configuration/domain.xml file. If you are running in standalone mode, you will configure the resource adapter in the standalone/configuration/standalone.xml file.

More details there How to migrate from AS5 or AS6 to Wildfly

  • Migration of the shell scripts, integration test scripts, deployment scripts.

Application code and configuration migration

Here is the list of tasks implying some rewriting inside your application code.

  • Migration JEE 5 to JEE 6
  • Upgrade to JPA 2.0
  • Update your SOAP Implementations using JBossWS-CXF
  • Upgrade Hibernate from 3 to 4
  • Replacing JBOSS Cache by Infinispan Cache
  • Configure JAX-RS / Resteasy changes
  • Fix Hibernate’s sequencer
  • Replace JBOSS AOP Interceptors : JBoss AOP was used by the EJB container. However, in AS 7, the EJB container uses a new mechanism. If your application uses JBoss AOP, you need modify your application code as follows.
  • Migrating JNDI : Migrating JNDI namespaces
  • Update the datasources : link
  • Rewriting of your RMI Code : oss 5 and 7 are totally different and this kind of communication will not work.
  • Using CDI instead of plain old Singletons


Here is a list of useful tools to assist you in your migration.

  • IronJacamar : to update your datasource configuration
  • Tattletale : to find the application dependencies
  • Gilder : An application for migrating the configuration of JBoss AS 5-based servers to JBoss AS 7-based servers.
  • Tools and tooling to migrate to JBOSSS 6 : Link
  • Upgrades to newer versions of WildFly or JBoss EAP may be handled using the JBoss Windup migration tool. JBoss Windup migration tool



The disappointing quest for an Headless CMS in 2017

In 2017, this blog is powered by Hexo.js. However I am looking for a replacement since Hexo.JS is lacking of crucial features.


TLDR : HexoJS is too limited, I want online post edition!

I have been recently working to replace the technology powering my blog. A major point is that I am disappointed with its theme. I would like to replace it, with a new technology Vue.JS, for which I have already discussed there.

Since I am replacing the whole front-end, I have been using the great plugin hexo-generator-json. However I still have major issues with my assets (stored with the posts) and it is not really compatible with a CDN solution.

The second feature I am missing, is the possibility to edit my post online. I am an user of Medium and I love the mobile application to create and edits my posts as well watching statistics. A thing I did not think at first, is the impossibility to create new posts with Hexo.JS without an computer. Indeed, to generate your site, you have to generate it, using a full Node.JS environment, commiting, pushing on GITHub your modifications, deploy the docker container and so on. A lot of tasks I have mostly automated but yet, I don’t have a CI Environment available for it.

I did not want to switch back to Drupal and WordPress, equals for me as a bloated solution, slow and hard to tune. I wanted a compromise : why not having a NoSQL Database, a light REST backend, an AdminUI and that’s all. At the beginning of this blog, it was my plan to build this backend, but I decided shortly to concentrate on the content, rather than on the code.

Fortunately, the technologies have evolved and I made a list of Headless CMS / API-First CMD and tested them.

Headless CMS, what is it ?

Headless CMS

Headless CMS

I won’t spend too much time in the details, a good description has been done there.

Basically, legacy / traditional CMS are highly coupled solutions where the following components are tied :

  • Database : SQL Databases
  • Backend : PHP or worse
  • Front-End : Templated front end or theme highly coupled with the backend API. Unmodifiable at best, throwable at worst.
  • Separated WS / RPC : External service to access the backend data, not used by the front-end.
  • Admin UI : Bundled Admin UI.

Usually this kind of CMS are stored in one big block called WordPress, Drupal, Joomla and so on.

The good news is that even these famous solutions are evolving to apply the following modern and well-known principles :

  1. Decoupled front-end : CMS frontends should be decoupled. The UI will access to the blog data and content using an REST API. UI for Headless CMS are usually using technologies as Angular, React or Vue.JS
  2. Responsive front-end : Headless CMS enales the possibility to create various UI depending of your devices, smart watch, website, search engine etc.
  3. NoSQL Database : Handling documents and content is the speciality of NoSQL databases allowing to add your own custom fields, categories and organization.
  4. Framework : Such Headless CMS should provide libraries or framework to access to the content and handling the security as NPM modules and so on.
  5. DevOps : Such solution should be dockerized.

 My expectations

I am expecting from an Headless CMS to contains :

  • a REST backend
  • Documented RESTFul Apis
  • a database driver compatible NoSQL
  • a bundled Admin UI accessing by an API to the REST Backend
  • a docker image or docker compose
  • possibility to add custom fields
  • possibility to handle markdown format for the edition
  • Cloud FS Storage for my medias
  • Optimized solution : I don’t want a new wordpress installation
  • Node.JS solution : I want a lightweight solution
  • Self hosted solution : I want to deploy it on Google Cloud.


The list of experiments and my opinion about it.

Directus : No!

Docker-compose was not running (I used this project). The docker instructions worked for me.

I launched it and soon enough I received a lot of technical alerts wasting my pleasure of a fresh installation.

Directus / Error message

Directus / Error message

My last blocking point, and the reason I have rejected : I did not find any way to create a content category (called table) in the admin UI. Seems to manipulate the SQL Database to create them : no thanks (rant here).

 GetMesh : Meh

Uh Uh, a Java solution to power a small blog : no thanks.


 Drupal and WordPress : Hydra CMS

Too big, too well-known. The REST API is for sure the next security hole of these solutions.

But the reason of my reject, the UI cannot be separated from the backend!! And why would I like a UI embedded in my backend when I want to create a SPA WebSite ?

I will use them when they will have deleted their UI from the installer.

I suggest to call them HydraCMS.

GraphCMS : Hipster$$CMS



Looks Great but I want my own self-hosted solution and don’t want to pay for that.

Site here

Ghost : GirlyCMS

Honestly, I had a crush with Ghost. Sexy, a great installer, a great documentation, everything to tempt me like an attractive woman.

The problem is that Ghost has almost everything to charm me but he has an embedded UI!!!

I don’t want an UI, I want to build mine ūüôĀ

Apart from that point, GhostCMS is really great.

Ghost CMS

Ghost CMS

It even has an Slack integration and loves Markdown!!

Ghost CMS Site

Cockpit : Blind CMS

Cockpit CMS

Cockpit CMS

Listed in the Awesome CMS List, Cockpit CMS is a rather small solution.

The good points are :

** Docker is working fine. ** The concepts and architecture are OK. ** Nice AdminUI, I really appreciated the way to create my collections

But what really disappointed me was :

** No documentation (REST and so on). For an developer it’s unusable ** PHP : There is no documentation and the REST API is coded in PHP.. Meh ** Lonesome developer yes he is brave, we should encourage him, but he is freaking alone.

In summary, I think that this project goes in the right direction but took some tough and spiky path. PHP is clearly not the appropriate language for such solution. Compared to an Express server, the amount of work to be delivered is too high. It really needs more contributors (actives) to create a good solution and fill the big documentation blackhole. I cannot help since I don’t want to code again in PHP but the solution could be great.

Site is here


Well at the first glance, I rejected, could not find any Docker image. Or the few ones were not working. But my first attempt was dumb. KeystoneJS is not an Headless CMS by itself it’s rather an implementation of a CMS, fully customizable to create your own blog!

Powered by Express and Node.JS, two technologies I am particularly fond of!

The site is there

The positive sides of KeyNodeJS :

  • A slick project creator using Yeoman!
  • Modern technologies, I think the best to create a CMS
  • The bundle is containing what I am expecting (AdminUI, REST Backend, NoSQL Database(mongoDB))
  • Fully customizable collections and so on

The negative points are :

  • Maybe too much code to begin with
  • What is the maturity of the base implementation ?
  • How much effort requested to build its own website ?
  • I think I did not find yet a NPM module to build a REST Client


I have rejected most of these solutions.

  • I tried two times an installation and to migrate my data in DirectUS but I gave up. I don’t believe in the concepts.
  • The lack of API Documentation in Cockpit (HTML or a la Swagger) is blocking my attempt to use it and migrate my data. The fact that the solution is developed in PHP is blocking my wish to support them. And I don’t like much PHP REST Backend to be honest.
  • I really love Ghost but I don’t want their UI, I want mine. Otherwise I would have use it.
  • I tried to use Drupal and WordPress, but the requested system resources + the fact I cannot disable the UI are a big NO for me.

The consequence is that I am using KeystoneJS and I hope I won’t have too much work to power a new version of my blog.

Stay tune!
