Microservices, Monoliths, and NoOps

Monolithic Applications A monolith application, in layman terms, is where entire functionality of the application is packaged together as a single unit or application. This unit could be JAR, WAR, EAR, or some other archive format, but its all integrated in a single unit. For example an online shopping website will typically consists of customer, product, catalog, checkout, and other features. Another example is of a movieplex. ...

Java Web App Architecture In Takes Framework

I used to utilize Servlets, JSP, JAX-RS, Spring Framework, Play Framework, JSF with Facelets, and a bit of Spark Framework. All of these solutions, in my humble opinion, are very far from being object-oriented and elegant. They all are full of static methods, untestable data structures, and dirty hacks. So about a month ago, I decided to create my own ...

JAXB Is Doing It Wrong; Try Xembly

JAXB is a 10-year-old Java technology that allows us to convert a Java object into an XML document (marshalling) and back (unmarshalling). This technology is based on setters and getters and, in my opinion, violates key principles of object-oriented programming by turning objects into passive data structures. I would recommend you use Xembly instead for marshalling Java objects into XML ...

Dangerous Words

Ludwig Wittgenstein was one the greatest philosophers of 20th century. His book Tractatus Logico-Philosophicus addresses the limits of language and its relationship with reality. A friend of mine, great polemicist, suggested me to read it some years ago to understand one of his favourites conversational deux ex machina: “I can’t prove that, because of the inherent insufficiency of the language.” ...

Dismantling invokedynamic

Many Java developers regarded the JDK’s version seven release as somewhat a disappointment. On the surface, merely a few language and library extensions made it into the release, namely Project Coin and NIO2. But under the covers, the seventh version of the platform shipped the single biggest extension to the JVM’s type system ever introduced after its initial release. Adding ...

ChronicleMap – Java Architecture with Off Heap Memory

My last post was written a couple of weeks ago and after some valid feedback I’d like to clarify a couple of points as a preface to this article. The main takeaway from ‘Creating millions of objects with Zero Garbage‘ should be that with Chronicle you are not ‘limited’ to using jvm allocated on-heap memory when writing a Java program. Maybe ...

Deploying Code Fast? Here’s How to Tell If You Broke Something

Here at Takipi, we’re in the error tracking business. Each day, Takipi is used to track more than 500,000 errors across hundreds of different companies.

Writing Clean Tests – Trouble in Paradise

If our code has obvious faults, we are very motivated to improve it. However, at some point we decide that our code is “good enough” and move on. Typically this happens when we think that the benefits of improving our existing code are smaller than the required work. Of course, if we underestimate our return of investment, we can make ...
