CSS Wizardry
NOVEMBER 9, 2018
Despite having been called CSS Wizardry for over a decade now, there hasn’t been a great deal of CSS-related content on this site for a while. Let me address that by combining my two favourite topics: CSS and performance. CSS is critical to rendering a page—a browser will not begin rendering until all CSS has been found, downloaded, and parsed—so it is imperative that we get it onto a user’s device as fast as we possibly can.

This is article was written by Dirceu Pereira Tiegs, Site Reliability Engineer at Auth0, and originally was originally published in Auth0. Auth0 provides authentication, authorization, and single sign-on services for apps of any type (mobile, web, native) on any stack. Authentication is critical for the vast majority of apps. We designed Auth0 from the beginning so that it could run anywhere: on our cloud, on your cloud, or even on your own private infrastructure.

Web Performance is not only about understanding what makes a site fast. It’s about creating awareness amongst both developers and non-developers. Performance is a feature and needs to be prioritized as such. Performance is a topic that has interested me for a long time. I remember when I learned about dynamic programming, greedy or divide and conquer algorithms.

JavaScript is the main cause for making websites slow. Ten years ago it was network bottlenecks, but the growth of JavaScript has outpaced network and CPU improvements on today's devices. In the chart below, based on an analysis from the HTTP Archive , we see the number of requests has increased for both first and third party JavaScript since 2011. The following chart shows the growth in the total size of JavaScript from 2011.

Created by Alastair Robertson , bpftrace is an open source high-level tracing front-end that lets you analyze systems in custom ways. It's shaping up to be a DTrace version 2.0: more capable, and built from the ground up for the modern era of the eBPF virtual machine. eBPF (extended Berkeley Packet Filter) is in the Linux kernel and is the new hotness in systems engineering.

A look at the roles of architect and strategist, and how they help develop successful technology strategies for business.

I'm offering an overview of my perspective on the field, which I hope is a unique and interesting take on it, in order to provide context for the work at hand: devisi

With the enormous attack surface of cloud providers like AWS, Azure, and GCP, why aren't there more security problems? Data breaches and cyber attacks occur daily. How do you explain the unreasonable effectiveness of cloud security? Google has an ebook on their security approach; Microsoft has some web pages. Both are the equivalent of that person who is disgustingly healthy and you ask them how they do it and they say "I don't know.

A lot of companies—even if they are aware that performance is key to their business—are often unsure of how, when, or where performance testing sits within their development lifecycle. To make things worse, they’re also usually unsure whose responsibility performance measuring and monitoring is. The short answers are, of course ‘all the time’ and ‘everyone’, but this mutual disownership is a common reason why performance often gets overlooked.

Decentralized systems will continue to lose to centralized systems until there's a driver requiring decentralization to deliver a clearly superior consumer experience. Unfortunately, that may not happen for quite some time. I say unfortunately because ten years ago, even five years ago, I still believed decentralization would win. Why? For all the idealistic technical reasons I laid out long ago in Building Super Scalable Systems: Blade Runner Meets Autonomic Computing In The Ambient Cloud.

A common question that I get is why do we offer so many database products? The answer for me is simple: Developers want their applications to be well architected and scale effectively. To do this, they need to be able to use multiple databases and data models within the same application. Seldom can one database fit the needs of multiple distinct use cases.
