MetaSpace in Java is a consider advance over PermGen speace, delivering superior speed, stability and scalability for JVM based applications. It is an important componant of contemporary Java versions and develpers should be aware of its use to optimise the memory utilisation of their programmes....

When a compiler translates source code into bytecode, it is known as abytecode compiler. The JVM or interpreter converts the bytecode into instructions that can be executed by the hardwareprocessor. A JVM also makes it possible for the bytecode to be recompiled by a just-in-time (JIT) c...
And Kotlin, nominally a JVM language, offers a compiler technology called Kotlin/Native that uses LLVM to compile to machine-native code. What is LLVM? At heart, LLVM is a library for programmatically creating machine-native code. A developer uses the API to generate instructions in a...
Apache Cassandra is built on Java, and runs in the Java Virtual Machine (JVM). Summarily, Cassandra relies on JVM Garbage Collection, or JVM GC, in order to occasionally identify and reclaim unused memory so there is always enough space to allocate new objects. Java GC performance is, howeve...
Now that you have an overview of what Prometheus is, letâs step back for a minute and look at what is meant by âmonitoringâ in order to provide some context. Following that I will look at what the main components of Prometheus are, and what Prometheus is ...
Platforms like Salesforce Heroku can handle languages like Python, Ruby on Rails, Node.js, Scala, Java and all JVM languages and more. Integration with existing workflow strategies including Git, Continuous Integration and DevOps mean there’s no need to add more processes. What is Salesforce...
In the first design decision we take issue with, Microsoft has decided to make “Any CPU/Prefer 32-bit” the default in Visual Studio 2012 when creating .NET 4.5 applications. This is unfortunate because users assume “Any CPU” meant the same thing as it previously did (the application wil...
Apache Cassandra allows for a great deal of performance tuning on top of your typical JVM performance tuning. Another option that is often overlooked is table level compression options that are capable of being configured when creating or changing tables, a feature that is enabled by default. Back...
on adding keywords like property (which I think is a good idea, based on my experience with CLOS) now is a different question. It will also be interesting to see if the open sourcing of Java makes the process more open to such suggestions (as long as they’re compatible with the JVM)...
