Demonstrating Monitoring Solutions for CF and Lucee

The presentation introduces several new features in Java 8 including lambdas, default methods, streams API, and method references. Lambdas allow for anonymous functions and simplify implementing interfaces with single methods. Default methods allow interfaces to define implementations while maintaining backwards compatibility. The streams API provides a functional-style way to process collections through filtering, mapping, matching, and reducing operations. Method references allow referring to methods without anonymous classes.

Linaro aims to improve Linux support for ARM processors. They created LAVA (Linaro Automated Validation) to automate testing of new kernels on ARM hardware. LAVA needs a way to trigger test runs when kernel builds finish. Linaro implemented an XML-RPC API with HTTPS and token-based authentication to securely allow remote triggering of test runs. They open sourced the server and client code to make it easy for others to add authenticated XML-RPC to projects.

- Android applications are composed of components that can span multiple processes and tasks. Components have managed lifecycles as they transition between states like active, paused, and stopped. - Inter-process communication (IPC) allows components in different processes to share data. The Android Binder system provides efficient IPC using parcelables and bundles to pass data across processes. - Activities represent screens or views within an application. Tasks group related activities that maintain a back stack. By default each application runs in its own process but additional processes can be used to isolate components from one another.

The document discusses the implementation of processes and threads in an operating system kernel. It covers topics like process control blocks (PCBs) that store process state and metadata, data structures like queues that the kernel uses to manage processes and threads, and how the kernel implements key operations on processes and threads like creation, suspension, activation, and destruction through manipulating the PCBs. It also discusses implementing synchronization mechanisms like semaphores using primitives like test-and-set instructions.

Write a program in C or C++ which simulates CPU scheduling in an operating system. There is only one CPU. The scheduling algorithm you will implement is FCFS. You can implement Round Robin for extra credits. You are suggested but not required to use standard template library data structures such as vector and deque. This program is lengthier than previous assignments. Please allocate sufficient time. Assumptions: (a) We will assume the processes engage in CPU bursts, Input bursts and Output bursts, ignoring other interrupts. (b) We will assume that all processes are doing Input through the same device which can process one Input burst at a time. (b) We will assume that all processes are doing Output through the same device which can process one Output burst at a time. (c) We will assume the system starts out with no processes active. There may be processes ready to start at once. Data structures: You will need a struct or class to represent one process. The program requires 4 queues: Entry, Ready, Input and Output. You can use deque for the queues (unless you prefer to write your own implementation of queue). The items stored on the queues are pointers to processes. You can think of Entry queue as the queue where the processes reside (e.g. on disk swap space) before they are loaded into memory. You can also have variables Active, IActive and OActive (pointers to processes), which points to the active processes on the CPU, the input device and the output device, respectively. Constants: You can declare the following constants: MAX_TIME is an integer = length of the whole run. Use the value 500. IN_USE is an integer = maximum number of processes that can be in play at once (that is, Active/IOActive processes if any, plus those that are in Ready/IO queues). Use the value 5. 2 HOW_OFTEN is an integer indicating how often to reprint the state of the system. Use the value 25. You may declare some other optional constants. They are not necessary if you choose to use STL: QUEUE_SIZE is an integer guaranteed larger than the maximum number of items any queue will ever hold. Use the value 20. ARRAY_SIZE is an integer = size of the array to define in a process. It is the maximum number of bursts for a process. Use the value 10. Feel free to add more constants as you see fit. The process data structure: A process needs to contain (at least) the following data: ProcessName is the name of the process, a string. ProcessID is an integer, the ID number for the process. This is assigned by the system (i.e., your program). Use consecutive values such as 101, 102, 103, etc. History is an array or vector of pairs of the form (letter, value). They are from the supplied input file, described below. Sub is a subscript into the array/vector History CPUTimer counts clock ticks for the process until it reaches the end of the CPU burst for FCFS (or end of the quantum for RR). IOTimer counts clock ticks for the process until it reaches the end of the I/O burst. You need t.

The document discusses operating systems and processes. It defines an operating system as software that controls hardware and manages resources. A process is a program in execution that has a unique ID and state. Processes go through various states like running, ready, blocked/waiting, and terminated. Threads are lightweight processes that can be scheduled independently and share resources within a process. User-level threads are managed in libraries while kernel-level threads are managed by the operating system kernel.

Apache Traffic Server is a high performance caching proxy that can improve performance and uptime. It is open source software originally created by Yahoo and used widely at Yahoo. It can be used as a content delivery network, reverse proxy, forward proxy, and general proxy. Configuration primarily involves files like remap.config, records.config, and storage.config. Plugins can also be created to extend its functionality.

The document summarizes the analysis of the TensorFlow machine learning library using the PVS-Studio static code analyzer. Some key findings include: 1. PVS-Studio found 64 instances of false positives related to the DCHECK debugging macro that were suppressed. Explanations of how to address false positives were provided. 2. Various PVS-Studio settings like disabling diagnostics rules and excluding automatically generated files helped filter the analysis output. 3. Genuine errors found include a null pointer dereference that could lead to undefined behavior and a redundant null check.

The document discusses different types of looping statements in programming languages. It describes while, do-while, for, and foreach loops. It explains that while and do-while loops check a condition each iteration, for loops allow initializing and changing a counter, and foreach loops iterate over array elements. It also mentions break and continue statements that alter loop execution flow. Examples of each looping statement are provided with links to online code samples.

The document provides an introduction to operating systems and key concepts such as processes, virtual memory, and multitasking. It discusses how the CPU uses registers to perform computations and access memory. It explains that an operating system allows multiple programs to run simultaneously through time-slicing and context-switching between processes. Each process has its own virtual address space and sees its own "virtual machine" presented by the operating system.

Java is one of the most popular languages and it's very important to understand the performance of Java servers. Modern JVMs compile the Java code in runtime using Just-In-Time (JIT) compiler and such JIT compiled code runs very close to optimized native code in terms of speed. When understanding performance, it's important to know how Java works and we can also measure the performance using key metrics like Throughput and Latency. After measuring the performance, we can use profilers to understand the application behavior and find performance bottlenecks. In this session, we will look at how Java manages the memory and how it optimizes the Java code using JIT compilation. We will also look at how we can use the Java Flight Recorder (JFR) to profile the JVM and find performance bottlenecks. Finally, we can look at how "Flame Graphs" can be used to identify the most frequent code-paths quickly and accurately.

Scala is a programming language created in 2001 that runs on the Java Virtual Machine. It aims to be scalable by combining object-oriented and functional programming features. Some key characteristics include its Java-like syntax that makes Java libraries and frameworks accessible, static typing for performance and documentation, and use of traits to decompose large classes and avoid fat objects. Functional programming is also supported through treating functions as first-class objects and avoiding side effects.

The document discusses different types of looping statements in programming languages including while, do-while, for, and foreach loops. It provides examples of the syntax for each loop and explains their usage - while and do-while loops check a condition each iteration, for loops initialize and increment a counter, and foreach loops iterate over array elements. Break and continue statements are also covered which can exit or skip iterations in loops respectively.
