After 15 years, I still think Java has not evolved for the better. In fact I hate it now.

Yup! I said it. I really hate Java now. I mean, really.

Maybe I'm too old and completely lost the plot, maybe I am simply not relevant anymore as a developer, maybe I just "don't get it" or maybe I am a dumbass. Whatever it is, I have many issues with it now and I need to get some of that off my chest to at least have the feeling I am not crazy, or at least not so much.

Annotations.

A couple of years ago (actually more like 15), annotations were introduced and at the beginning, I though they were a great idea. I still do. Now I hate them, and that's not the language's fault. The problem is that many frameworks and tools make way too much use of them. The original idea in part was to remove a lot of boilerplate code and allow the devs to focus on what actually needed to get done. But nowadays, in many frameworks, THAT'S ALL YOU SEE!! Yep, you simply open up a class where the main function should be and all you see is 37 different annotations that invisibly define what this application does. There is one line of code in the main method, and the rest is taken on by magic by all the different annotations. Some of those scan packages for other classes that also have annotations, and so on. So instead of making the code simpler, it almost completely hides the basic structure of how the app is wired and unless you know exactly what all these annotations imply, you're pretty much stuck spending a lot of time figuring it out. None of that is more intuitive or simpler. Annotations are like a hammer, you can use it to build a house or punch yourself in the dick. The current frameworks are punching devs in the dick with annotations. Ouch ...

Masquerading as a functional language.

Face it Java, you are not the belle of the ball anymore. You are an old, verbose, bloated, object oriented ancestral language. That's it. No amount of lipstick will make that pig any more attractive. Own it.

20 years ago, object oriented programming was THE way to go as far as programming went. Everything was transitioning from older languages to the newer more maintainable (apparently, which is BS, but that's for another blog post) OOP options. At that time it made perfect sense. Internet was booming and more and more applications became web applications. We started banking online, we started using email in the browser and companies were letting go of more traditional desktop apps in favor of more modern solutions. Java and .NET were right in the center of that revolution. And it made perfect sense. Object oriented langages were so very well adapted to work with relational databases. Mapping your domain classes to the relational model was somewhat simple and intuitive. Not without its challenges, but very very adequate.

And that was absolutely fine. I coded more applications with Struts (remember the good ol' days ?) and Hibernate than I care to remember. And I had a blast, it was a great challenge and you could really leverage the power of object oriented programming. You could (when applicable) leverage many design patterns and make really elegant, testable and maintainable code. Ok, you had 1200 xml configuration files that had 5000 lines on average. That's what it was and it was an OK tradeoff, you could work with that. But that was before Twitter, Facebook, Linkedin and many other web applications you probably never heard of that take in a lot of user provided data. That was before you could have millions of users hitting your app and services, before Big Data, before NoSQL's explosion, the commercial use of machine learning and AI, and the emergence of the 3 big cloud providers (AWS, GCP, Azure).

Where am I going with this ? Well it's relatively simple. The market, the devs, the communities and tools started broadening their horizons and using different tools to meet the new needs. Spark was coded with Scala, Docker and Kubernetes are coded with Go and many machine learning tools and libraries are coded with Python, to only name that one. What these languages have in common is the functional component which Java does not have. And that's OK in my book. But in trying to stay relevant I guess, they added many functional aspects to the language that simply don't have their place in my opinion. It really feels like they ran out of ideas and simply want to jump on that functional hype train so they can still think it's really popular.

When I was introduced to Java, they took great pride in saying that it was a pure or exclusively object oriented language. That's what I was expecting it to remain. And I am not one of the purists that would lose their shit over the fact that it had primitives like ints, doubles, etc ...

The SDK is not enough to even get started.

This one really grinds my gears. You can't even get started coding a minimally decent application without 37 tools. Simply having the SDK installed on your workstation barely gets you out of the gate. What you need aside from that is :

A build tool

Yep, in 2019, you need to install either (from what I know, there might be more) Gradle, Maven or Ant (if you enjoy pain) if you want to build your project. Yes, you can compile with javac provided with the SDK, but that's pretty much it. You have to find some way to automate the rest of the building process, hence the use of a 3rd party tool.

A unit test framework

Yep, that as well in 2019 still slips through Java's fingers. I don't get it. Why ? Unit testing is built it in to several languages, and that has been the case for many years now. Check out this list to see what languages have built-in support for unit testing. You will notice that Go and Rust are present, along with Python.

On this one I need to be honest though, if I hadn't coded in Go for 3 years before returning to Java, I probably never would have had an issue with how it's unit tested. But then again, it's refreshing to go look elsewhere to see what other ideas people are having to realize that what you are currently using isn't the bee's knees as much as you thought. It is so much simpler to just start coding and creating your tests without having to import this and that and the other thing. All is already set up and ready. No need to modify class paths or ignore files or folders, no configuration whatsoever. I had that before, and not any more and I miss it so much.

Some kind of JSON / XML parser

You would figure that someone would have had the idea to add built-in parsing for JSON and XML by now. There are very few moments when you won't at least load some configuration in one of those 2 formats. Simplifying that would actually bring a lot of value to the developers and would save quite a lot of time.

Bloating caused by being bloated, verbose and verbose about being bloated ...

That I can say infuriates me the most. Why all this code and all those dependencies ? Why all that inexplicable bloating ?

I did a quick test with Spring Boot, which is supposed to be the standard for magnificent, quick and easily maintainable services. Like magic they said .. Well, not so much. To even get 1 endpoint that did a hello world kinda thing I needed 11 files and a little under 400 lines of code and configuration .. Almost feels like a React app o_O . And still using xml files to configure 27 million things, in 2020, is not part of the solution by any means.

And I haven't built it yet, which will probably fail and take 10 minutes .. be right back ..

Ok, so the build did not fail, but the resulting war file was a staggering 20 Megabytes. Again, for 1 endpoint that answers "Hello World". Is it just me ? Am I being a real prick ? Am I the asshole ? What bit did I not understand that makes me not think this is normal ? Plus that war file does not run independently, it needs to run in some container or server thing to be of any use to anybody. Which leads me up to my next point ...

Create actual executables already !!

One of the most amazing parts of Go is that it builds an executable that has all the dependencies included. Plain and simple. So if you are building a CLI application, simply run the executable. Same for a a REST service, simply build it with your desired options and there you have it, an executable that will run your service. No Tomcat, no Jersey thing, no additional tool required. Just run it. That not only simplifies the development process, but also the conainterizing of whatever it is you are building. With the same Go example, you can use "scratch" as a base for your container and simply copy the built binary and it will run fine, no other dependencies. This makes for very lightweight containers that build very fast.

Nobody gives a crap about the 'build once run anywhere' thing. At least I don't.

That argument is also a dead one to me. I never leveraged that in any way shape or form, ever. I never went to a colleague and said : "Thank god we can run this jar anywhere, we would have been fucked otherwise.". I just don't see why they went through all that trouble with the runtimes and the this and that.

I coded for several years with a language that had to be built for a specific platform, and it never caused any headaches. We either built with the provided switches for the target platform, or even better, on the exact Docker container in which it is intended to run. Plus, .NET only runs on Windows and it is very well adopted by a large community of developers that do wonderful things.

If you're into AI or machine learning, you most likely aren't using Java.

That's a big thing nowadays, adding AI and machine learning to whatever service you are putting out there. And if you want to leverage any of the most popular platforms or libraries, you'll have to make use of some functional language, usually Python or R. That's just how it is. Other languages than Java are far better suited for that type of computing. So even if you want to keep a Java only stack in your organization, you'll get some limitations on the type of tools you can actually integrate.

Dependency Upgrades: why commerce software engineers need a policy and process

For most commerce software engineers, dependency management includes upgrades and best practice suggests upgrading dependencies proactively. In order to ensure a smooth process and one that is maintained properly, it is best to have a well-defined policy and process.

Why you need a policy and  process 

All software depends on other software to accomplish useful tasks. Even the smallest  hello world  program depends on the libraries of the language it is written in. Typically, as a piece of software  gets more sophisticated it depends on more third-party software or libraries. Leveraging existing third-party libraries is a standard practice for  commerce engineers  to enable faster development.   

However, vulnerabilities and bugs of dependencies become vulnerabilities and bugs of the software the dependencies are included in. As a result, dependencies must be chosen with due consideration, and constantly monitored.  Best practice is to not only upgrade dependencies proactively, but to also be on the latest versions of libraries as often as possible.

Why Upgrade Dependencies? 

The single biggest reason for upgrading dependencies is  security. Most software has vulnerabilities that are gradually fixed over time. Upgrading dependencies, is  the  simplest way  to avoid security issues. The latest versions can introduce new vulnerabilities that are not yet discovered. However, it is still safer to upgrade in order to fix known vulnerabilities.

Most of the  changes between versions  are  bug fixes  and  performance improvements, that’s another good reason to upgrade. In recent tests, a docker version upgrade gave a significant boost to the performance numbers. 

Other reasons to upgrade include being able make use of new features, avoiding giant upgrade steps as it is always easier to update in smaller increments, and it is also easier to upgrade a single dependency if everything else is up to date. 

Upgrade Experiences Commerce software developers should be upgrading dependencies on a regular basis. Here are a few examples of good, bad and ugly dependency upgrades  that inform the upgrade process.  

The Good 

Overall library upgrades  should be  smooth or have relatively few issues. Good libraries maintain backward compatibility, and provide suitable replacements for any APIs that are deprecated. As a result, upgrading such libraries should  involve  only  minor code changes. Good migration guides, and well-crafted deprecation warnings  make this process relatively painless. Recent examples of these include various Apache Commons libraries,  Mockito,  and  RxJava.  

The Bad  

Every now and then an upgrade does not go according to plan, and unexpected issues arise due to not having the bugs or changes well documented.   Recent example of this occurred with an upgrade to Guava version 25.  Guava upgrades are typically seamless and  jumping to version 25 was expected to be a simple version bump.

However, intermittent errors occurred in performance tests because of a misbehaving cache. The intermittent nature of the errors meant that they were difficult to track down, resulting in a days-long test to locate the issue. To allow enough time to deal with such surprises, it is best to do upgrades at the beginning of a release cycle.

The Ugly 

Sometimes  an upgrade can get ugly.  This is typically the case when a number of dependencies have to be upgraded in lockstep. This problem will be  exacerbated  if regular upgrades are not done, and several upgrades of versions need to take place in one go. 

As an example, a recent Spring upgrade required upgrading Cucumber. Upgrading Cucumber required upgrading Spring. Also resulting in needing to upgrade Camel, Junit,  Servicemix, and Gemini. Attempting to untangle this dependency web was challenging.  

Automation 

Upgrading dependencies is not the most exciting work for a commerce  engineer. To ensure upgrades are quick and happen often, it is strongly recommended to leverage all automated tools available.

For example, Versions Maven Plugin is best to use for maven projects  to generate reports listing the libraries that have new versions available. The plugin can also auto-upgrade the versions directly in source code. Most languages and frameworks have similar tooling available. 

It is worth noting to only use the auto-upgrade feature to do revision, and minor version upgrades. These upgrades are typically quick and require minimal code changes. Overall, the plugin is a huge time saver.

A major version upgrade is often a more conscious decision to upgrade with the understanding that such an upgrade will require some work. 

New vulnerabilities are discovered  every day, and it is hard to keep up with without some  automation.

Use a security and  license  compliance  tool, e.g. Black Duck, to  identify vulnerabilities and license compliance issues in the open source libraries.  

Lastly, it is recommended to create a robust suite of functional and performance tests that ensure library upgrades do not have negative consequences. 

The Upgrade Process – what a strong process looks like

Identify the libraries to be upgraded.  Leverage an automated tool in this step. Most languages and frameworks have one. E.g. Use Versions Maven Plugin  for Maven projects.  

Ensure version being upgraded to does not have known security vulnerabilities, and license issues. Before changing a single line of code one can verify candidate versions using a security compliance tool  e.g.  Black Duck. 

Do the bare minimum code change to upgrade the version i.e.  fix  any compilation errors, and any  functional  test failures. Don’t try to use any new features at this point. 

Verify performance. Run your whole performance test suite.  

As much as possible, do the upgrades at the beginning of  a  release  cycle  to give  you  time to live with any surprises that might come up.  

As an optional exercise – use the new features. Take a look at release notes of the new versions, check if there is anything that catches the eye and would be helpful. Use your judgement to determine if it might be useful to spend a bit of time on this. 

In  closing, be sure to continue to learn from experiences and fine tune this process.

Dependency Upgrades: why commerce software engineers need a policy and process

Why you need a policy and  process 

Why Upgrade Dependencies? 

The Good 

The Bad  

The Ugly 

Automation 

Upgrading dependencies is not the most exciting work for a commerce  engineer. To ensure upgrades are quick and happen often, it is strongly recommended to leverage all automated tools available.

A major version upgrade is often a more conscious decision to upgrade with the understanding that such an upgrade will require some work. 

New vulnerabilities are discovered  every day, and it is hard to keep up with without some  automation.

Use a security and  license  compliance  tool, e.g. Black Duck, to  identify vulnerabilities and license compliance issues in the open source libraries.  

Lastly, it is recommended to create a robust suite of functional and performance tests that ensure library upgrades do not have negative consequences.

Reviews:

“Tuna güzel bir iş çıkarmış spring ile uğraşacaksanız bu dersi almanızda fayda var her bölümü tane tane anlatıyor sadece bölümler biraz daha kısa olabilirdi alışkanlıktan mıdır nedir bilmiyorum ama uzun videolarda bazen dağılıyorum.” (Halil Ibrahim Baykal)

“Tuna provides one relatively big app (comparing to one course) for you to play with, and he walks you through the code to explain the concept. This is nice since you can play with this app in anyway you like. However I am still missing the depth of knowledge in the explanation, and I find his speech too slow. Hence 3.5 stars” (Cuong Huy To)

“This is a very good course, covering all the basics of Spring MVC and AngularJS. I recommend it to people already familiar with Java and web development that want to broaden their expertise: this is a good place to start. The examples are clear and exhaustive, though sometimes there is a bit of confusion in the xml configuration files for Spring, but fixing that couple of problems can be a good way to deepen your understanding. The instructor replies very quickly to questions and help requests.” (Marco Magnatti)

Riders of Asgard - Back-end

In my last article, I spoke about game analytics and how I am using them for Riders of Asgard. In this article I am going to speak about the back-end services and how I went about implementing them.

The back-end system for Riders of Asgard is primarily responsible for the leader boards system and the hints and tips that are displayed on the loading screens. Furthermore it handles the sharing of high scores and Tweets the high scores to the official Riders of Asgard Twitter page (@ridersofasgard). It also periodically does a geo-lookup on the IP Address of a player and sets the country flag accordingly, as can be seen in the screen shot below.

Core Web Service

The core of the back-end service is a RESTful web-service built using Java and Spring Boot. Spring Boot is part of the Spring Framework which is currently owned by Pivotal. Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications that you can "just run". We take an opinionated view of the Spring platform and third-party libraries so you can get started with minimum fuss. Most Spring Boot applications need very little Spring configuration.

Included with the base Spring Boot application, I am using Data JPA with the Repository Pattern, Thymeleaf, Web, and Web Jars. All these are connected to a MySQL server. Spring Data’s mission is to provide a familiar and consistent, Spring-based programming model for data access while still retaining the special traits of the underlying data store.

It makes it easy to use data access technologies, relational and non-relational databases, map-reduce frameworks, and cloud-based data services. This is an umbrella project which contains many sub projects that are specific to a given database. The projects are developed by working together with many of the companies and developers that are behind these exciting technologies. Coupled with the Repository Pattern means that the service is able to scale with the system as the project grows, MySQL no longer able to cope, no problem add the PostreSQL connector and restart the application.

The Repository Pattern allows the repository to mediate between the data source layer and the business layers of the application. It queries the data source for the data, maps the data from the data source to a business entity, and persists changes in the business entity to the data source. A repository separates the business logic from the interactions with the underlying data source or Web service.

Spring Web forms the basis of the web-service and is tightly coupled with WebJars. WebJars are client-side web libraries (e.g. jQuery & Bootstrap) packaged into JAR (Java Archive) files which allow us to explicitly and easily manage the client-side dependencies in JVM-based web applications.

Thymeleaf is a Java XML/XHTML/HTML5 template engine that can work both in web (Servlet-based) and non-web environments. It is better suited for serving XHTML/HTML5 at the view layer of MVC-based web applications, but it can process any XML file even in offline environments. It provides full Spring Framework integration. In web applications Thymeleaf aims to be a complete substitute for JSP, and implements the concept of Natural Templates: template files that can be directly opened in browsers and that still display correctly as web pages.

Back-end Service

The foundation of the back-end service is an Ubuntu droplet running on Digital Ocean. DigitalOcean, Inc. is an American cloud infrastructure provider headquartered in New York City with data centers worldwide. DigitalOcean provides developers cloud services that help to deploy and scale applications that run simultaneously on multiple computers. As of December 2015, DigitalOcean was the second largest hosting company in the world in terms of web-facing computers.

On top of our droplet we have deployed Docker containers for Java and MySQL that run the Spring Boot Web-service and MySQL database respectively. Docker is an open-source project that automates the deployment of applications inside software containers. Docker containers wrap up a piece of software in a complete file system that contains everything it needs to run: code, run time, system tools, system libraries – anything you can install on a server. This guarantees that it will always run the same, regardless of the environment it is running in.

Docker provides an additional layer of abstraction and automation of operating-system-level virtualization on Linux. Docker uses the resource isolation features of the Linux kernel such as cgroups and kernel namespaces, and a union-capable file system such as OverlayFS and others to allow independent "containers" to run within a single Linux instance, avoiding the overhead of starting and maintaining virtual machines.

This abstraction allows us to run multiple web-services and databases on the single droplet if required and when necessary we can scale up the droplet seamlessly without it affecting the individual systems running in their Docker containers. Furthermore we can move the containers to separate servers if required and if a container gets compromised or unstable, it will not effect the other containers on the system.

Continuous Integration

The entire system is designed with Continuous Integration in mind and is driven from the DevOps mindset. In software engineering, continuous integration (CI) is the practice of merging all developer working copies to a shared mainline several times a day. Grady Booch first named and proposed CI in his 1991 method, although he did not advocate integrating several times a day. Extreme programming (XP) adopted the concept of CI and did advocate integrating more than once per day - perhaps as many as tens of times per day. We use a combination of Jenkins and Artificatory for our system.

Jenkins helps to automate the non-human part of the whole software development process, with now common things like continuous integration, but by further empowering teams to implement the technical part of a Continuous Delivery. It is a server-based system running in a servlet container such as Apache Tomcat. It supports SCM tools including AccuRev, CVS, Subversion, Git, Mercurial, Perforce, Clearcase and RTC, and can execute Apache Ant and Apache Maven based projects as well as arbitrary shell scripts and Windows batch commands. The creator of Jenkins is Kohsuke Kawaguchi. Released under the MIT License, Jenkins is free software.

As the first, and only, universal Artifact Repository Manager on the market, JFrog Artifactory fully supports software packages created by any language or technology. Artifactory is the only enterprise-ready repository manager available today, supporting secure, clustered, High Availability Docker registries. Integrating with all major CI/CD and DevOps tools, Artifactory provides an end-to-end, automated and bullet-proof solution for tracking artifacts from development to production.

All the Continious Integration is driven from our Gitlab Community Edition server. GitLab is a web-based Git repository manager with wiki and issue tracking features, using an open source license, developed by GitLab Inc. The software was written by Dmitriy Zaporozhets and Valery Sizov from Ukraine. The code is written in Ruby. Later, some parts have been rewritten in Go. As of Dec 2016, the company has 150 team members and more than 1400 open source contributors. It is used by organisations such as IBM, Sony, Jülich Research Center, NASA, Alibaba, Invincea, O’Reilly Media, Leibniz-Rechenzentrum (LRZ) and CERN.

Part of our DevOps process is the abundant use of Unit Tests and Integration Testing that is run on Jenkins using the Maven build tool. On a successful build, the relevant Docker Container is informed that there is an update and it will schedule the update when the system is not being utilised. Should the system end up being more than three versions behind, we will manually schedule the upgrade by bringing up a brand new Docker container with the new version and decommissioning the current one.

DevOps (a clipped compound of development and operations) is a term used to refer to a set of practices that emphasizes the collaboration and communication of both software developers and other information-technology (IT) professionals while automating the process of software delivery and infrastructure changes. It aims at establishing a culture and environment where building, testing, and releasing software can happen rapidly, frequently, and more reliably.

In computer programming, unit testing is a software testing method by which individual units of source code, sets of one or more computer program modules together with associated control data, usage procedures, and operating procedures, are tested to determine whether they are fit for use. Integration testing (sometimes called integration and testing, abbreviated I&T) is the phase in software testing in which individual software modules are combined and tested as a group. It occurs after unit testing and before validation testing. Integration testing takes as its input modules that have been unit tested, groups them in larger aggregates, applies tests defined in an integration test plan to those aggregates, and delivers as its output the integrated system ready for system testing.

Maven is a build automation tool used primarily for Java projects. The word maven means "accumulator of knowledge" in Yiddish. Maven addresses two aspects of building software: first, it describes how software is built, and second, it describes its dependencies. Contrary to preceding tools like Apache Ant, it uses conventions for the build procedure, and only exceptions need to be written down. An XML file describes the software project being built, its dependencies on other external modules and components, the build order, directories, and required plug-ins. It comes with pre-defined targets for performing certain well-defined tasks such as compilation of code and its packaging.

Conclusion

So some of you reading this may have noticed a trend towards Java and Open Source solutions, this was a conscious decision that we made. I have always advocated for Java and Open Source solutions in the enterprise and my drive in Gobbo Games is to show that these technologies can be used in an enterprise without the need to pay exorbitant license fees.
