You Call that Micro, Mr. Docker? How OSv and Unikernels Help Micro-services S...rhatr OSv is the new open source unikernel technology that combines the power of virtualization and micro-services architecture. This combination allows unmodified applications to be packaged just like Docker containers while at the same time outperform bare-metal deployments. Yes. You've heard it right: for the first time ever we can stop asking the question of how much performance would I lose if I virtualize. OSv lets you ask a different question: how much would my application gain in performance if I virtualize it. This talk will start by looking into the architecture of OSv and the kind of optimizations it makes possible for native, unmodified applications. We will then focus on JVM-specific optimizations and specifically on speedups available to micro-service oriented applications when they are being deployed on OSv.

Messaging, interoperability and log aggregation - a new framework
Messaging, interoperability and log aggregation - a new frameworkTomas Doran In this talk, I will talk about why log files are horrible, logging log lines, and more structured performance metrics from large scale production applications as well as building reliable, scaleable and flexible large scale software systems in multiple languages.
Why (almost) all log formats are horrible will be explained, and why JSON is a good solution for logging will be discussed, along with a number of message queuing, middleware and network transport technologies, including STOMP, AMQP and ZeroMQ.
The Message::Passing framework will be introduced, along with the logstash.net project which the perl code is interoperable with. These are pluggable frameworks in ruby/java/jruby and perl with pre-written sets of inputs, filters and outputs for many many different systems, message formats and transports.
They were initially designed to be aggregators and filters of data for logging. However they are flexible enough to be used as part of your messaging middleware, or even as a replacement for centralised message queuing systems.
You can have your cake and eat it too - an architecture which is flexible, extensible, scaleable and distributed. Build discrete, loosely coupled components which just pass messages to each other easily.
Integrate and interoperate with your existing code and code bases easily, consume from or publish to any existing message queue, logging or performance metrics system you have installed.
Simple examples using common input and output classes will be demonstrated using the framework, as will easily adding your own custom filters. A number of common messaging middleware patterns will be shown to be trivial to implement.
Some higher level use-cases will also be explored, demonstrating log indexing in ElasticSearch and how to build a responsive platform API using webhooks.
Interoperability is also an important goal for messaging middleware. The logstash.net project will be highlighted and we'll discuss crossing the single language barrier, allowing us to have full integration between java, ruby and perl components, and to easily write bindings into libraries we want to reuse in any of those languages.

Vadim Pisarevsky, Software Engineering Manager at Intel, presents the "Making OpenCV Code Run Fast" tutorial at the May 2017 Embedded Vision Summit.
OpenCV is the de facto standard framework for computer vision developers, with a 16+ year history, approximately one million lines of code, thousands of algorithms and tens of thousands of unit tests. While OpenCV delivers decent performance out-of-the-box for some classical algorithms on desktop PCs, it lacks sufficient performance when using some modern algorithms, such as deep neural networks, and when running on embedded platforms. Pisarevsky examines current and forthcoming approaches to performance optimization of OpenCV, including the existing OpenCL-based transparent API, newly added support for OpenVX, and early experimental results using Halide.
He demonstrates the use of the OpenCL-based transparent API on a popular CV problem: pedestrian detection. Because OpenCL does not provide good performance-portability, he explores additional approaches. He discusses how OpenVX support in OpenCV accelerates image processing pipelines and deep neural network execution. He also presents early experimental results using Halide, which provides a higher level of abstraction and ease of use, and is being actively considered for future support in OpenCV.

It provides tips for compiling applications with Intel Composer XE 2013 using the -mmic flag. While some applications like DGEMM require tuning to achieve peak performance, others like Gaussian09 and Povray require patches and multi-step configurations to build for Xeon Phi. There is also an effort underway to port the pkgsrc packaging system to help bring more software packages to the Xeon Phi.
Bits of Advice for the VM Writer, by Cliff Click @ Curry On 2015
Bits of Advice for the VM Writer, by Cliff Click @ Curry On 2015curryon The document discusses Cliff Click's experience building the HotSpot JVM over 20 years. Some key points:
- Cliff Click has 40 years of coding experience including building compilers, distributed systems, operating systems, and Java virtual machines.
- There are many design choices to consider when building a VM such as portability, footprint, threading model, garbage collection approach, and JIT vs interpreter.
- Implementing native calls is complex due to differences in calling conventions between Java and native code as well as ensuring the GC can find live references across calls.
- Techniques like safepoints, cooperative preemption, and polling worked well for HotSpot. The C2 compiler's graph-based

Development of MLR, ANN and ANFIS Models for Estimation of PCUs at Different ...Journal of Soft Computing in Civil Engineering Passenger car unit (PCU) of a vehicle type depends on vehicular characteristics, stream characteristics, roadway characteristics, environmental factors, climate conditions and control conditions. Keeping in view various factors affecting PCU, a model was developed taking a volume to capacity ratio and percentage share of particular vehicle type as independent parameters. A microscopic traffic simulation model VISSIM has been used in present study for generating traffic flow data which some time very difficult to obtain from field survey. A comparison study was carried out with the purpose of verifying when the adaptive neuro-fuzzy inference system (ANFIS), artificial neural network (ANN) and multiple linear regression (MLR) models are appropriate for prediction of PCUs of different vehicle types. From the results observed that ANFIS model estimates were closer to the corresponding simulated PCU values compared to MLR and ANN models. It is concluded that the ANFIS model showed greater potential in predicting PCUs from v/c ratio and proportional share for all type of vehicles whereas MLR and ANN models did not perform well.
Building Security Systems in Architecture.pdf
Building Security Systems in Architecture.pdfrabiaatif2 Building security systems are essential for protecting people, property, and assets within a structure. These systems include a range of technologies and strategies such as surveillance cameras (CCTV), access control systems, alarm systems, security lighting, and motion detectors. Modern security solutions often integrate smart technology, allowing remote monitoring and real-time alerts through mobile devices. Access control systems, like key cards or biometric scanners, ensure that only authorized individuals can enter certain areas, enhancing both safety and privacy. Alarm systems, whether triggered by unauthorized entry, fire, or environmental hazards, play a critical role in emergency response. Additionally, video surveillance acts as both a deterrent and a tool for investigating incidents. An effective building security system is carefully planned during the design phase, taking into account the building's size, purpose, and potential risks. Ultimately, robust security systems are vital for ensuring peace of mind, protecting lives, and preserving valuable assets.
