Screen printing involves coating a mesh screen with photo-emulsion. Once coated and exposed to UV light, the emulsion hardens, creating open areas where ink can pass through to print an image. A squeegee is used to force ink through the open areas of the screen onto the printing surface. Different types of inks, such as water-based or plastisol, have advantages and disadvantages for different applications. Proper equipment like screens, frames, and inks are required to produce high quality, consistent screen prints.
NLCMG - Performance is good, Understanding performance is better nlwebperf
This document summarizes a presentation on understanding website and application performance. It discusses diagnosing performance issues, identifying bottlenecks, and incorporating performance testing into the development process. Key topics covered include availability and response time metrics, psychological costs of slow performance, analyzing transactions and resource usage, queueing theory, and common monitoring and analysis tools. The presentation calls for collaboration to develop a standard body of knowledge on web performance best practices.
The document provides an overview of using the WebPageTest API and scripting capabilities to programmatically run tests and analyze results. It discusses submitting requests, polling for status, retrieving results including PageSpeed scores and video frames, and using the Python library and command line tool for batch processing. Example scripts are shown to simulate user interactions and test different conditions. Hidden features like custom connectivity profiles and console.log output are also highlighted. The document encourages persistence when troubleshooting tests, as the WebPageTest platform can sometimes behave unexpectedly.
This document discusses performance metrics for monitoring and optimizing a social network application. It recommends collecting metrics at various levels, including development, system health, and page-level performance. It describes tools for each level like Debug Toolbar, New Relic, Graphite, Cloudwatch, and PgFouine. Graphite is highlighted as a tool for storing vast amounts of metrics data that can then be queried and visualized in different ways. The document provides examples of specific metrics that could be tracked, like database query times, cache performance, task processing times, and deploy monitoring. It emphasizes that collecting a wide range of metrics across the application stack helps identify bottlenecks and optimize performance.
- Modern APM solutions must be able to adapt automatically to support fast-changing IT applications with multiple technologies.
- APM solutions need to provide both a wide overview for operations teams and deep insights for developers to troubleshoot problems.
- Alerts from APM solutions should be actionable by pinpointing the right issues without false alarms, and the solution must be able to monitor applications effectively in production and test environments.

The document discusses Usabilla's experience with an AWS outage in 2011 and how it led them to rearchitect their infrastructure on AWS. It outlines their initial AWS setup with EC2 instances and RDS, and how after the outage they added multi-AZ for high availability. It then summarizes how they started over from scratch to fully leverage AWS services like Route 53, CloudFront, load balancers, auto-scaling groups, S3 and MongoDB.
This summary provides an overview of the Nimbuzz architecture and technologies:
Nimbuzz is a communication platform that allows calling, messaging, and file sharing across mobile devices and computers using popular IM networks. It uses a microservices architecture with small, stateless services and external components communicating over XMPP. The platform is built on Ejabberd, an XMPP server written in Erlang, which provides features like concurrency, distribution, and high availability. Caching, database, and data processing best practices are employed to optimize performance for millions of daily users.
Web performance optimization is important for driving traffic, improving user experience, increasing revenue, and reducing costs. The majority of optimization opportunities exist on the frontend rather than the backend. Most websites do not set caching headers properly, resulting in many resources being unnecessarily redownloaded by users. While some resources truly change frequently, studies show that a large portion could actually be cached longer. Improving caching practices through longer caching headers, bigger browser caches, and smarter purging logic could significantly improve performance for many users.

2deHands.be - Tuning a Big Classifieds Sitenlwebperf
2dehands.be is the market leader for classified ads in Belgium.
You don't get to become big without proper performance of your site. In this talk I will focus on the solutions we came up with in terms of frontend performance, which tools are available and how to interpret the results. The second part I will also give insight on backend tools like Varnish, Memcached, Redis. Especially which performance related problems you might encounter when amount of users and pageviews increase.
Performance no longer happens in your datacenter… Before your web application gets assembled in the browser of your end users it takes various routes via ISPs, 3d Parties or different (mobile) devices. Monitoring availability and performance nowadays requires an end user approach. Based on the Nimsoft philosophy, measuring from the outside in, Gijsbert Wiesenekker (Sales Engineer) shows via best practices and real life examples what it takes to measure correct and take action.
The document discusses various equipment used in screen printing, including:
- Photo emulsion, which hardens when exposed to UV light to create stencils on screens.
- Squeegees, which are used to push ink through screens to produce consistent results.
- Scoop coaters, which spread photo emulsion in a thin, even layer on screens.
- Film positives, which are opaque artworks used to expose screens.
- UV light sources needed to expose emulsion and create stencils.
- Clamps and tapes used to prepare screens for printing.
