The document discusses improvements and changes to the Sizzle selector engine in jQuery 1.8. Key points include:
- Matching and filtering performance improved by around 10% on average.
- ID selections rooted at an element improved by 300%.
- Bugs were fixed in how different browsers handle certain selectors with querySelectorAll and matchesSelector.
- Support for combining multiple combinators in selectors was improved.
- More changes are planned prior to release, including implementing a compiler to avoid re-looping elements.
JsViews - Next Generation jQuery TemplatesBorisMoore
Come and see the future of jQuery Templates, as it moves from Beta1 towards a V1 product. The new jQuery Templates is taking two forms: JsRender – lean and mean, for fast rendering of templates as strings, and JsViews – for powerful interactive browser apps in which Data Link and Templates work hand-in-hand. See how with declarative data linking and templating together, creating powerful data-driven UI is easy, whether using MVVM patterns or binding directly to JSON, and whatever the richness or complexity of the underlying data.
jQuery UI is already building its future data-bound widgets on top of this technology. With JsViews and JsRender integration between jQuery UI controls and your own data and UI becomes trivially straightforward.

Last year, AOL adopted a new content strategy and has positioned itself as a premier destination for original content. Core to this strategy is having reusable, highly efficient and optimized common code and experiences at scale, which is where jQuery comes in. Check in with Dave Artz to see how jQuery has helped his front-end standards team tackle unique challenges like optimizing 3rd party widget performance, overriding plugin functionality, and managing dependencies and updates across 100+ sites spanning multiple back-end platforms.
Getting Started with Angular - Stormpath Webinar, January 2017Matt Raible
YouTube video of webinar: https://www.youtube.com/watch?v=Jq3szz2KOOs
This presentation is from a Stormpath Webinar I did on January 12, 2017. It was designed to teach developers how to build apps using Angular. Topics covered: tools needed, how to setup a project, how to run/deploy and how to deploy it to the cloud. I also talked about TypeScript, components, RxJS, routing, CSS frameworks and security.
It's a talk that I gave on Talk.JS Singapore @ July 1st, 2013. Talking about introduction to building SPA with AngularJS.
I only have 2 weeks experience using AngularJS by the time I wrote this, so there might be a lot of missing gap about development best practices.
My trully intention is just to share my experience to a beginner like me.

Declaring Server App Components in Pure JavaAtlassian
Today, server app developers declare their components using a mixture of technologies that includes atlassian-plugin.xml, Spring XML files, and Spring Scanner. This fragmented approach comes with its own learning curve and an array of pitfalls.
In this talk, Andrew Swan from Atlassian's Server Java Platform team will describe how server app developers can declare their Spring components in pure Java code. This approach is cleaner, more powerful, more flexible, easier to reason about, and more industry-standard. Attendees will also learn about a new Atlassian library that facilitates this approach by providing easy importing and exporting of OSGi services.
Attendees will come away being immediately able to start using Java-based configuration in their server apps. Links to documentation and working sample code will be provided.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

- actually that selector would work if the special characters were escaped and :checkers was a custom pseudo.\n- OK, but there were actually bugs\n
Every browser has bugs in querySelectorAll, even webkit.\n- If you know what I did in the last version of jQuery, you’ll know about my long standing relationship with attributes. IE8’s QSA doesn’t handle boolean attributes very well.\n
