HKG15-409: ARM Hibernation enablement on SoCs - a case study --------------------------------------------------- Speaker: Grygorii Strashko Date: February 12, 2015 --------------------------------------------------- ★ Session Summary ★ Hibernation on ARM devices is a long-wanted feature, with multiple ways of achieving it - in-kernel, fully userspace, or a combination. This presentation will give brief overview of these methods, and will discuss the effort required in enabling in-kernel ARM hibernation to the TI platform. We will also share the pre-requisites for enabling this on other SoCs. -------------------------------------------------- ★ Resources ★ Pathable: https://hkg15.pathable.com/meetings/250837 Video: https://www.youtube.com/watch?v=dJqCbTfKrMk Etherpad: http://pad.linaro.org/p/hkg15-409 --------------------------------------------------- ★ Event Details ★ Linaro Connect Hong Kong 2015 - #HKG15 February 9-13th, 2015 Regal Airport Hotel Hong Kong Airport --------------------------------------------------- http://www.linaro.org http://connect.linaro.org

Intel Processor Trace is a hardware feature that recording information about software execution with minimal impact to system execution. Existing hardware is unfriendly to enable Intel PT in guest because the implementation of shadow ToPA is very complex. Intel PT VMX improvements will treat PT output addresses as Guest Physical Addresses (GPAs) and translate them using EPT that serves to simplify the process of Intel PT virtualization for using by a guest software. We have submitted a patch set to enable Intel PT in XEN HVM guest for collecting hardware behavior, backwards debugging for GDB and so on. We also plan to implement system mode for tracing XEN hypervisor and guest's behavior if necessary.

Currently, several initiatives promote XEN hypervisor into the automotive area as a base of complex virtualized systems. To support those initiatives and plunge into the automotive world XEN should fit at least two requirements: it should be appropriately certified and to be able to host a security domain. Leaving behind certification topic, here we focus on security domain hosting capability of XEN. Particularly on keeping RT guarantees for the specific domain. This talk is a presentation of the investigation on a XEN hypervisor applicability to building a multi-OS system with real-time guarantees being kept for one of the hosted OSes. During this presentation following topics would be outlined: - experimental setup - experimental use-cases and their motivation - received results and discovered issues - solutions and mitigation measures for discovered issues

ATOS is an Auto Tuning Optimization System that is able to find automatically the best performance/size tradeoff from a build system and a training application. The input of ATOS tools are a build command and a run command. From the build command, ATOS will infer an internal build configuration that it will run with different sets of compiler options. These build configurations are executed with the run command from which code size and performance will be extracted. From the set of build configurations that ATOS explores, one can extract the preferred trade-off between code size and performance. The extracted build configuration can be archived and replayed later in order to generate the optimized executable without any modification into the initial build system. The nice property of ATOS is that NO modification of the sources or the makefiles are needed. ATOS can work on any large/deep project, as soon as the compiler used is gcc or LLVM under Linux.

Kernel development is often associated with rebooting crashed machines, debugging over serial consoles, and an unwiedly development cycle. Developers know that short development cycles are incredibly important for programmer productivity. The QEMU machine emulator and virtualizer offers a way to test kernels inside virtual machines without risk of hanging the physical machine. It also makes kernel debugging easier than between physical machines. The kernel development with QEMU allows kernel code changes to be tested within seconds. This talk covers methods of compiling, testing, and debugging kernels using QEMU. Common approaches include building a custom initramfs or sharing the host file system with a virtual machine. Advanced use cases like cross-architecture development and device driver bringup are also possible using QEMU. This presentation is aimed at anyone wishing to shorten their kernel development cycle and overcome some of the hurdles of developing low-level software. Stefan Hajnoczi, Red Hat

With the recent open-sourcing of JDK Mission Control, there is even more interest in Java Mission Control and Java Flight Recorder than ever. A lot has changed, but these tools still remain on the forefront of debugging and troubleshooting Java issues, both during development and in production. This session covers these recent changes, migrating from earlier versions, and what the JDK Mission Control community’s plans are for the future.

Spinning up new instances fast, and effective JIT compilation, may be game changers these days, but they are just a part of the story. What about leaks in the code taking all gained speed away? Java Flight Recorder is an event based tracing framework. It is built directly into the Java runtime and provides access to all internal data, while allowing additional custom enhancements. The goal is to present the value of JFR and how it is able to achieve low overhead (cca 1%). We explain fundamental elements and the performance. We also explore newly added features in current and upcoming releases of JDK Mission Control 8.x.

In this deck, I quickly summarize how people have dealt with logging in Docker historically and then describe a comprehensive approach to logging and monitoring in Docker, based on research and customer interviews. While Docker adds a welcome layer of abstraction to the deployment of applications, it also challenges assumptions on how those applications should be managed. I discuss a comprehensive approach for collecting logs and metrics into a centralized platform and dissect the latest additions to Docker itself (log drivers, stats).

Project Loom is a huge step forward in the way the JVM implements concurrency. It introduces a concurrency model that is straight forward to use without sacrificing scalability. It gets a lot of traction since it was released in preview mode in Java 19, however, it is not a silver bullet that will magically resolve everything. In this talk we will go through the essentials of the project and help understand when and where applying it will make your life as a Java developer significantly better.

“Just leave the garbage outside and we will take care of it for you”. This is the panacea promised by garbage collection mechanisms built into most software stacks available today. So, we don’t need to think about it anymore, right? Wrong! When misused, garbage collectors can fail miserably. When this happens they slow down your application and lead to unacceptable pauses. In this talk we will go over different garbage collectors approaches and understand under which conditions they function well.

NEXT Insurance is a US based insurtech startup, revolutionizing the small business insurance industry. NEXT was founded 6 years ago and ever since we have been building our microservices in Kotlin. During this period we grew from a small startup with one backend developer(myself) to a $4B company with 150 backend developers. We have written over 1.2M lines of code in Kotlin and aquired long mileage with this programming language. In this talk I am going to share our experiences, insights and pains. This talk was given in JFokus 2022

On September 2007 I started a journey. I left a position as a System Architect in a big Software company and started a career as an independent consultant. This have been a hell of a journey. Two years ago I returned to the warmth of the payroll (business was doing great btw as a freelancer). Along these years I found myself many times answering questions on how this is done. This lead me to the conclusion that the know how may be of an interest to the community and I want to share with you. I believe that anyone who considers becoming an independent contractor/consultant will greatly benefit from this talk.

Next Insurance was founded at the beginning of 2016, and the first lines of its production code started accumulating in May 2016. As the first back-end developer, I started writing in Java and out of curiosity was experimenting with Kotlin. Kotlin had just seen its 1.0 release two months earlier. A year later, Next Insurance’s entire back-end development team is writing all the code in Kotlin. We already have 8 microservices and several AWS lambda functions all written in Kotlin. Migration from 1.0.x to Kotlin 1.1 was smooth, and the developers are happy. This presentation covers the language’s features and why I think it is awesome and fits perfectly with my company’s architecture.

Next Insurance was founded in the beginning of 2016 and first lines of our production code started accumulating in May 2016. In the beginning I have started writing in Java and experimenting with Kotlin, which saw its 1.0 release two months earlier. 6 months later, the development of our backend services has totally shifted to Kotlin. We still keep a few classes in Java just to make sure that the integration remains seamless but the vast majority of our codebase is written in Kotlin. In this talk I will cover the language features and why I think it is awesome, from null safety to smart casts and data classes. We will also look into the future with 1.1 async/await feature and more.

Garbage collection is the most famous (infamous) JVM mechanism and it dates back to Java 1.0. Every Java developer knows about its existence yet most of the time we wish we can ignore its behavior and assume it works perfectly. Unfortunately this is not the case and if you are ignoring it, GC may hit you really hard.... in production. Furthermore the information that you may find on the web can be a lot of times misleading. In this event we will try to demystify some of the misconceptions around GC by understanding how different GC mechanisms work and how to make the right decisions in order to make them work for you.

A traditional Java profiler consists of two components. One collects profile data from the running application and the other is a visualization user interface to query the data. The profiler capabilities are limited by the data collected but also by the provided reports and functionality. This can be limiting when it comes to complex query of data. In this session we will introduce mjprof. It is an open source textual visualization profiler. It is extremely powerful as it enables you to compose a sequence of simple steps (monads) such as filters, transformations, group-by which let you slice and dice the data to pinpoint the problem. Working with mjprof resembles working with UNIX pipes. We will explain how to use this tool and present use cases and success stories, using this profiler in the last months. mjprof is written in Java and can be found on github as part of the AdoptOpenJDK project.

Life as a software engineer is so exciting! Computing power continue to rise exponentially, software demands continue to rise exponentially as well, so far so good. The bad news are that in the last decade the computing power of single threaded application remains almost flat. If you decide to continue ignoring concurrency and multi-threading the gap between the problems you are able to solve and your hardware capabilities will continue to rise. In this session we will discuss different approaches for taming the concurrency beast, such as shared mutability,shared immutability and isolated mutability actors, STM, etc we will discuss the shortcomings and the dangers of each approach and we will compare different programming languages and how they choose to tackle/ignore concurrency.

Heather Hedden, Senior Consultant at Enterprise Knowledge, presented “The Role of Taxonomy and Ontology in Semantic Layers” at a webinar hosted by Progress Semaphore on April 16, 2024. Taxonomies at their core enable effective tagging and retrieval of content, and combined with ontologies they extend to the management and understanding of related data. There are even greater benefits of taxonomies and ontologies to enhance your enterprise information architecture when applying them to a semantic layer. A survey by DBP-Institute found that enterprises using a semantic layer see their business outcomes improve by four times, while reducing their data and analytics costs. Extending taxonomies to a semantic layer can be a game-changing solution, allowing you to connect information silos, alleviate knowledge gaps, and derive new insights. Hedden, who specializes in taxonomy design and implementation, presented how the value of taxonomies shouldn’t reside in silos but be integrated with ontologies into a semantic layer. Learn about: - The essence and purpose of taxonomies and ontologies in information and knowledge management; - Advantages of semantic layers leveraging organizational taxonomies; and - Components and approaches to creating a semantic layer, including the integration of taxonomies and ontologies
