(phpconftw2012) PHP as a Middleware in Embedded Systems

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 discusses the inner workings of PHP including its architecture, core components like the lexer, parser, compiler and virtual machine. It covers key concepts like opcodes, variables as unions of C data types, and memory management. Understanding PHP internals like its stack and heap implementation, copy-on-write variables, and reference counting is important for optimizing performance and avoiding memory leaks. Resources and objects also have important internal representations that developers should be aware of.

This document discusses IncludeOS, an open source unikernel operating system.

The port is near completion with only optimization hooks remaining to be implemented and some test failures compared to x86_64.

This document summarizes the key points from a PHP user group meeting about using Composer: - Sven Rautenberg introduced himself and his background developing with PHP for over 15 years. He discussed using Composer to autoload PHP libraries and manage dependencies. - Attendees were encouraged to ask questions during or after the presentation. Sven explained how to install Composer and initialize a composer.json file to get started managing a project's dependencies. - Sven covered best practices for defining autoloading rules in composer.json using PSR-4 and PSR-0, and alternatives like classmaps and files. He emphasized the importance of semantic versioning and provided guidance on using version constraints

Modern developers use virtualized "single use" development environments to reduce time tweaking servers, allowing more time developing. Teams share configurations to eliminate endless "works for me" debug loops, while rebuilding and/or setup is a simple command taking minutes, not hours or days. This intro talk will create a base for attendees to build from and investigate the various technologies like Vagrant, VirtualBox, Puppet, Containers, and Virtual PHP. If your development environment is not virtualized, catch up, it's what all the "cool kids" are doing.

It describes profiling tools like XHProf that can analyze runtime performance. It also discusses opcode caching with extensions like APC that improve performance by caching compiled code. Finally, it cautions developers to be aware of how language features like traits actually work at the compiler level and can introduce unintended coupling.

REBOL is a simple yet powerful programming language that allows developers to quickly build applications. It has several advantages including being small in size, not requiring many files or configurations, and being very easy to learn and use. Some key things that can be done with just a few lines of REBOL code include creating graphical user interfaces, downloading and parsing web pages, and networking tasks like port scanning. The document discusses both strengths and weaknesses of REBOL, and encourages programmers to try it for its simplicity and flexibility.

Composer is a tool for dependency management in PHP projects that allows developers to declare project dependencies and have Composer install them. It resolves dependencies and runs installation tasks per project rather than globally. Major PHP frameworks like Symfony use Composer because it ensures projects always have the exact same dependency versions and avoids issues with PEAR's global installation approach. Composer has over 15,000 packages on its default repository Packagist and has seen 60 million package installations since 2012.

Building, managing and scaling a highly-available Puppet master in the cloud can be a painful and complex task. Masterless Puppet, together with PuppetDB and Bolt, can solve this pain in a horizontally-scaleable, cloud-native environment.

In Embedded system a set of applications used to perform a complex task or to create a product, which is typically another computer program or a system of programs. Tools are linked (or chained) together by specific stages. Output or resulting environment state of the tool becomes input or starting environment for the next one. By default the host contains some development tools which are called native tool-chain. Here is the presentation that shares mode details on components of tool-chain and how to build them for your own embedded distribution.

1) Hardware upgrades are often cheaper and provide more performance gains than slow, error-prone code optimizations. Profiling and caching can provide gains without changing code. 2) Premature optimization wastes time; optimize only after identifying bottlenecks through profiling. Simplify code through modularization instead of over-engineering. 3) Caching queries, pages, and computation results in memory provides major speedups with little effort compared to direct code optimizations. Match buffer sizes for efficient PHP-to-OS communication.

Is your patent a vanity piece of paper for your office wall? Or is it a reliable, defendable, assertable, property right? The difference is often quality. Is your patent simply a transactional cost and a large pile of legal bills for your startup? Or is it a leverageable asset worthy of attracting precious investment dollars, worth its cost in multiples of valuation? The difference is often quality. Is your patent application only good enough to get through the examination process? Or has it been crafted to stand the tests of time and varied audiences if you later need to assert that document against an infringer, find yourself litigating with it in an Article 3 Court at the hands of a judge and jury, God forbid, end up having to defend its validity at the PTAB, or even needing to use it to block pirated imports at the International Trade Commission? The difference is often quality. Quality will be our focus for a good chunk of the remainder of this season. What goes into a quality patent, and where possible, how do you get it without breaking the bank? ** Episode Overview ** In this first episode of our quality series, Kristen Hansen and the panel discuss: ⦿ What do we mean when we say patent quality? ⦿ Why is patent quality important? ⦿ How to balance quality and budget ⦿ The importance of searching, continuations, and draftsperson domain expertise ⦿ Very practical tips, tricks, examples, and Kristen’s Musts for drafting quality applications https://www.aurorapatents.com/patently-strategic-podcast.html

Kief Morris rethinks the infrastructure code delivery lifecycle, advocating for a shift towards composable infrastructure systems. We should shift to designing around deployable components rather than code modules, use more useful levels of abstraction, and drive design and deployment from applications rather than bottom-up, monolithic architecture and delivery.

Stream processing is a crucial component of modern data infrastructure, but constructing an efficient and scalable stream processing system can be challenging. Decoupling compute and storage architecture has emerged as an effective solution to these challenges, but it can introduce high latency issues, especially when dealing with complex continuous queries that necessitate managing extra-large internal states. In this talk, we focus on addressing the high latency issues associated with S3 storage in stream processing systems that employ a decoupled compute and storage architecture. We delve into the root causes of latency in this context and explore various techniques to minimize the impact of S3 latency on stream processing performance. Our proposed approach is to implement a tiered storage mechanism that leverages a blend of high-performance and low-cost storage tiers to reduce data movement between the compute and storage layers while maintaining efficient processing. Throughout the talk, we will present experimental results that demonstrate the effectiveness of our approach in mitigating the impact of S3 latency on stream processing. By the end of the talk, attendees will have gained insights into how to optimize their stream processing systems for reduced latency and improved cost-efficiency.
