A new JEP draft has been filed to create a no-op garbage collector: a GC that doesn't actually reclaim memory. This is aimed at aiding JVM implementers and researches and, to a lesser extent, ultra-performant applications that generate little to no garbage. If the JEP goes ahead, the new GC would be available together with the existing ones, and would have no effect unless explicitly activated.
LLD, which touts great performance improvements over GCC ld, will be included in LLVM 4 rc1 and enabled by default. Although the new linker is already able to build a running FreeBSD/amd64 base system, its inclusion in LLVM is still experimental and could be set back in rc2 if it causes problems.
Researchers at MIT have been working on a fork of LLVM to explore a new approach to optimizing parallel code by embedding fork-join parallelism directly into the compiler’s intermediate representation (IR). This, the researchers maintain, makes it possible to leverage most of the IR-level serial optimizations for parallel programs.
Java 9 is now officially feature complete, meaning the first bug-fixing phase has started. HTTP/2 Client didn't make it on time for the deadline and has been downgraded to an incubating feature. Since the objective now is to prepare Java 9 for general availability in July, it is very unlikely that any new JEP will be added at this point.
The Twitter Sponsored Solutions track at QConSF2016 features an engineering talk on JVMs Across the Data Center and unveils an in-house OpenJDK fork, the Twitter-JDK, with noted potential open-sourcing or release to broader public.
InfoQ recently sat down with Joan Wrabetz, CTO at Quali, and discussed the role ‘cloud sandboxes’ can take within the modern software development lifecycle (SDLC). Cloud sandboxes allow a user to create and publish replicas of infrastructure and application configurations for on-demand usage. The primary use cases for cloud sandboxes include development and quality assurance testing.
OpenJDK HotSpot may get Ahead-of-Time (AOT) compilation as early as Java 9. InfoQ covers the proposal submitted in September 2016.
IBM had many innovative news to share this year at their keynote at Java One. InfoQ was there to cover their keynote.
Day 1 of JavaOne 2016 topics: learning about Java 8&9 features, Docker for Java developers, and development tools for Java EE 8. InfoQ highlights a few of the day's interesting sessions.
Microsoft has open sourced Checked C, a research project meant to add bounds checking to C and C++.
Mark Stoodley, Architect at IBM talks to Rags Srinivas about Eclipse OMR project, an open-source virtual machine toolkit to help create runtime environments for any language.
IBM has created Eclipse OMR, an open-source virtual machine toolkit to create runtime environments for any language. OMR aims at leveraging general improvements in virtual machine technology across languages, like garbage collection or hardware integration. To achieve this, IBM is generalising its own JVM, J9.
Android N introduces a hybrid runtime using compilation + interpretation + JIT to obtain the best compromise between installation time, memory footprint, battery consumption and performance.
The LLVM team has announced the release of LLVM, which includes a few major deprecations, new C API headers, and Clang 3.8.
Censum, the Java garbage collection analysis tool by jClarity, has reached version 3.0. The main new features of the new version include the ability to analyse Safepoint logs, new graphs showcasing the behaviour of the G1 garbage collector, and a set of analytics to highlight whenever applications force to much OS activity.
