Adventures in Laravel and Performance: Looking beyond eloquent
•
0 likes•548 views
This document discusses performance issues that can arise when using Laravel and Eloquent ORM. It presents three solutions to handling custom form data with historical views: 1) using basic Eloquent queries, 2) using raw PDO queries, and 3) extending Eloquent. While solution 1 is easiest, it results in many queries. Solution 2 improves performance but bypasses Eloquent. Solution 3 extends Eloquent to leverage its models while improving performance over basic queries, though still not reaching raw PDO speeds and adding complexity. The document asks for feedback on possible improvements or alternatives.

Zend Server: Not just a PHP stack
There are a lot of tools available that can make developers life easier. Zend Server is one of them. The Zend products have come from a long way, but since the introduction of Zend Server the focus is more on a developers perspective than ever. The integrated tools make debugging, performance tuning, process offloading and deployment really accessible. Even extending it with your own needs is possible nowadays. The current PHP ecosystem gives every developer enormous amounts of power in creating applications without writing a lot of code.
In this talk I will show you how Zend Server can help you understand your own PHP application better, by using its tools to open the blackbox that your PHP application really is. This talk is not about selling Zend Server, but helping developers understand why reconsidering your development stack is always an option. Because in the end every developer likes to be a lazy developer.

Extending Ajax Events for all mankind
Presented 9/12/2009 at jQuery Conf 2009.
Like any good Javascript framework would, jQuery includes Ajax functionality into its core. In particular, though, jQuery has some interesting ways it approaches event handling with Ajax responses. We’re going to dive into this Ajax event mechanism, and see what fun we can have with extending it.
This talk will first review the various Ajax events and some common ways they are used. Then, we’ll investigate jQuery source code and see how each is accomplished. Armed with this knowledge, we’ll talk about some scenarios where you might want to extend these events with extra functionality, or even add your own custom Ajax events.
To move from the theoretical into the concrete, we will discuss two jQuery Ajax plugins I released, mpAjax and flXHRproxy, and look at how each needed in its own way to hook into the Ajax event mechanism and extend it.

Digital Banking in the Cloud: How Citizens Bank Unlocked Their Mainframe
Inconsistent user experience and siloed data, high costs, and changing customer expectations – Citizens Bank was experiencing these challenges while it was attempting to deliver a superior digital banking experience for its clients. Its core banking applications run on the mainframe and Citizens was using legacy utilities to get the critical mainframe data to feed customer-facing channels, like call centers, web, and mobile. Ultimately, this led to higher operating costs (MIPS), delayed response times, and longer time to market.
Ever-changing customer expectations demand more modern digital experiences, and the bank needed to find a solution that could provide real-time data to its customer channels with low latency and operating costs. Join this session to learn how Citizens is leveraging Precisely to replicate mainframe data to its customer channels and deliver on their “modern digital bank” experiences.

Introduction of Cybersecurity with OSS at Code Europe 2024
I develop the Ruby programming language, RubyGems, and Bundler, which are package managers for Ruby. Today, I will introduce how to enhance the security of your application using open-source software (OSS) examples from Ruby and RubyGems.
The first topic is CVE (Common Vulnerabilities and Exposures). I have published CVEs many times. But what exactly is a CVE? I'll provide a basic understanding of CVEs and explain how to detect and handle vulnerabilities in OSS.
Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application.
I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.
Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
