Techniques for Automating Obfuscation

Aggregated on: 2024-02-27 15:12:08

The rich Microsoft intermediate language (MSIL) of the .NET Framework is focused on application flexibility and inherently provides significant information about how an application was written. Obfuscation technology helps to secure the intellectual property contained in .NET Framework applications. Obfuscation tools rename symbols and rearrange code blocks to complicate decompiling. They also might encrypt strings that contain sensitive data. These tools also determine exactly which parts of your program you're really using (down to the method level). From there, the tools can parse out unneeded pieces, leaving you with the smallest possible executable. By removing unnecessary program elements and renaming identifiers to shorter names, an obfuscator can actually speed up programs. When combined with obfuscation and pruning, assembly linking provides a powerful packaging solution for .NET Framework applications.

Aggregated on: 2024-02-26 18:42:08

Java 17 heralds a new era in Java's evolution, bringing forth the Foreign Function and Memory API as part of its feature set. This API, a cornerstone of Project Panama, is designed to revolutionize the way Java applications interact with native code and memory. Its introduction is a response to the long-standing complexities and inefficiencies associated with the Java Native Interface (JNI), offering a more straightforward, safe, and efficient pathway for Java to interface with non-Java code. This modernization is not just an upgrade but a transformation in how Java developers will approach native interoperability, promising to enhance performance, reduce boilerplate, and minimize error-prone code. Background Traditionally, interfacing Java with native code was predominantly handled through the Java Native Interface (JNI), a framework that allowed Java code to interact with applications and libraries written in other languages like C or C++. However, JNI's steep learning curve, performance overhead, and manual error handling made it less than ideal. The Java Native Access (JNA) library emerged as an alternative, offering easier use but at the cost of performance. Both methods left a gap in the Java ecosystem for a more integrated, efficient, and developer-friendly approach to native interfacing. The Foreign Function and Memory API in Java 17 fills this gap, overcoming the limitations of its predecessors and setting a new standard for native integration.

Problems With Nested CompletableFuture in Java

Aggregated on: 2024-02-26 15:42:08

CompletableFuture was introduced in Java 8 for executing things in an asynchronous way. This can help to prevent the main thread from waiting to complete the execution of a particular block of code that is not needed for the main thread execution. CompletableFuture uses threads from ForkJoinPool.commonPool() for its execution, if there is no custom executor passed as an argument. If the parallelism is less than two, then CompletableFuture creates a new thread for each asynchronous task submitted. ForkJoinPool.commonPool() will have the number of threads based on the java.util.concurrent.ForkJoinPool.common.parallelism property set.
