This document discusses various computing concepts related to resources, data storage, and performance. It covers topics like hard disk drives, solid state drives, areal storage density, streams, filters, memory management, CPU performance, networking, and best practices for handling large amounts of data and potential failures. The key ideas are to use appropriate data structures, iterate/process data lazily, offload work to queues when possible, and design systems with failure in mind.

The OpenNTF Domino API is a community-developed Java API that provides an alternative to using the native Notes objects in Domino. It was created to bridge the gap between LotusScript and Java developers, remove the need for try/catch blocks and recycling, and take advantage of Java collections and helper methods. The API is deployed via an update site and its packages include core interfaces, extension interfaces, and implementation classes. It provides features like logging, transaction processing, and database event listeners. Developers can convert code by changing imports, removing unnecessary code, and using the API's helper methods.

Server-Side JavaScript with Nashorn Nashorn is a JavaScript engine that runs on the Java Virtual Machine (JVM), allowing for server-side JavaScript.

PHP 7.1 includes several new features and performance improvements. Some key new features are nullable types for typehints, void return types, support for iterable pseudo-types, class constant visibility modifiers, and the ability to catch multiple exception types in a single catch block. PHP 7.1 also provides over a 10% performance improvement compared to previous versions, due to enhancements like type specific opcode handlers and a new type inference system.

This document describes Dist::Surveyor, a tool created by Tim Bunce to determine which CPAN distributions and versions are installed on a system by analyzing the contents of a local Perl library directory. It discusses the challenges involved and different approaches considered. The key features of Dist::Surveyor are that it uses MetaCPAN to match installed module files to candidate distributions, scores distributions based on included modules, and can generate a list of exact distributions to reinstall a matching library.

This document provides an introduction to CPAN (Comprehensive Perl Archive Network), which is a repository for Perl modules and programs. It discusses how to install and configure a local Perl installation and leverage CPAN to easily install additional modules without modifying the system-wide Perl installation. The document also covers how to configure CPAN settings, install and update modules manually or via the CPAN shell, and find information on module quality and reviews.

This document summarizes a presentation about integrating the Laravel PHP framework with the Swoole extension. It discusses how Swoole provides high-performance asynchronous networking capabilities. Integrating Laravel with Swoole can boost performance by preloading the Laravel application and running requests in isolated "sandboxes" to prevent state from persisting between requests. This allows Laravel to take advantage of Swoole's asynchronous and non-blocking I/O without the typical overhead of Laravel's request lifecycle. Benchmarks show the integrated system can achieve a 5x performance increase over vanilla Laravel.

PHP is one of the most popular open source programming languages in the world. It powers some of the highest traffic sites in the world, and at the same time it powers some of the lowest traffic sites in the world. But have you ever wondered how it works under the hood? Have you been overwelmed by the thought of looking at the C code that runs PHP? Well, this talk is for you! We're going to explore how PHP works under the hood, by looking at a PHP implementation of it: PHPPHP! Have you ever wondered what an OPCODE Cache is really doing? Have you ever wondered what a T_PAAMAYIM_NEKUDOTAYIM is? Have you ever wondered why an interpreted languages has a compiler? We'll explore all of these topics, and more! And the best part of it all? You don't need to know C to understand the details! Using PHPPHP, we can explore the language details in a high level language, where things like memory management don't get in the way of the real content. If you've ever wanted to know how PHP works, this is the talk for you!

This document provides an overview of Amazon Web Services (AWS) and how PHP developers can use AWS services. It discusses: - Popular AWS services like Amazon S3, DynamoDB, SQS, SNS, and how they can be used. - Using the AWS SDK for PHP to interact with AWS services like S3 programmatically from PHP code using Composer, making API calls, and handling responses. - Features of the AWS SDK for PHP version 3 like asynchronous programming with promises, command pools for parallel requests, and waiters to wait for resources to be ready. - Examples of using the SDK to make API calls to S3 and other services, handle promises and errors, and

A short lightning talk rant on why you should use Perl::Critic as a supplemental tool to code/peer review

This document summarizes Kyle Drake's presentation on using EventMachine (EM) and EM::Synchrony to build fast, concurrent Ruby web applications without blocking I/O or callback hell. Key points include: - EM implements the reactor pattern to handle blocking I/O without threads by using callbacks and kernel threads. - EM::Synchrony avoids callback nesting by wrapping callbacks in fibers, allowing synchronous-looking code. - Sinatra can be made concurrent by running each request in its own EM::Synchrony fiber with little code change. - Ruby has strong options for building high-performance concurrent apps while maintaining productivity advantages over Node.js.

Reuven Lerner is a web developer and consultant who primarily works with Ruby on Rails and PostgreSQL. He teaches Rails courses and uses various tools like iTerm2, RVM, IRB gems, Emacs, Firefox plugins, Growl, and Pow in his development environment. Emacs is his editor of choice, which he has highly customized over the years using Lisp functions and key bindings.

The document discusses performance improvements in PHP7 compared to PHP5. The key improvement is the introduction of a just-in-time compiler (JIT) that compiles PHP code to machine code during execution. This was made possible by redesigning the zval internal data structure to reduce memory usage and optimize for JIT compilation. The new zval structure stores basic types directly instead of using references, and external structures are used for complex types like strings and arrays.

This document discusses why Ruby is a good programming language for operations staff. It notes that operations involves tasks like building servers, packaging, monitoring, and provisioning that can be programmed. While shell scripts and Perl are commonly used today, Ruby has advantages like allowing multiple versions of the same library, being beginner friendly due to tutorials and syntax, and its use of blocks for iteration, cleanup and separating concerns. Ruby also has good tooling for devops tasks like configuration management, logging and packaging that operations staff can benefit from due to the ability to write plugins for these tools.

As developers we write code everyday, only to frown at it a week after that. Why do we have such a hard time with code written by others and ourselves, this raging desire to rewrite everything we see? Writing code that survives the test of time and self judgment is a matter of clarity and simplicity. Let's talk about growing, learning and improving our code with calisthenics, readability and good design.

The United States has spent over $1 trillion on the war on drugs since 1971, resulting in hundreds of thousands of lives lost. Enforcement of drug laws has led to over 1.5 million arrests annually for nonviolent drug offenses and mass incarceration that disproportionately impacts minority communities. Treatment is more effective than incarceration for drug offenders, though only a small portion of the war on drugs budget supports public health policies. The war on drugs has also failed to curb drug use and has contributed to tens of thousands of deaths in Mexico from drug cartel violence.
