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.

I was recently conducting some exploratory work for a potential client when I hit upon a pretty severe flaw in a design decision they’d made: They’d built a responsive image lazyloader in JavaScript which, by design, worked by: immediately applying display: none; to the ; waiting until the very last of the page’s images had arrived; once they’d arrived, removing the display: none; and gradually fading the page into visibility.

People often ask me if developing for the cloud is any different from developing on-premises software. It really is. In this post, I show some of the reasons why that's true, using the Amazon Redshift team and the approach they have taken to improve the performance of their data warehousing service as an example. The Amazon Redshift team has delivered remarkable gains using a few simple engineering techniques: Leveraging fleet telemetry.

Flamescope is a new open source performance visualization tool that uses [subsecond offset heat maps] and [flame graphs] to analyze **periodic** activity, **variance**, and **perturbations**. We posted this on the Netflix TechBlog, [Netflix FlameScope], and the tool is on [github]. While flame graphs are well understood, subsecond offset heat maps are not (they are another visualization I invented a while ago).

High performance computing (HPC) clusters are able to solve big problems using a large number of processors. This is also known as parallel computing , where many processors work simultaneously to produce exceptional computational power and to significantly reduce the total computational time. In such scenarios, scalability or scaling is widely used to indicate the ability of hardware and software to deliver greater computational power when the amount of resources is increased.

Recently I was asked about content management systems (CMS) of the future - more specifically how they are evolving in the era of microservices, APIs, and serverless computing. For enterprise customers either undergoing or planning the digital transformation, this is an important question to ask. Enterprise customers spend a large chunk of their digital and marketing budget on CMS and associated modules such as digital asset management (DAM).

The cloud is always busy proactively working for you in the background. That’s how cloud services compete with each other to keep you in their ecosystem. Most of the cloud services we’ve talked about so far have been request driven.

As you probably know, Angular is all about building UI components. There are several excellent component libraries out there that you can use to build your own application, such as Angular Material , Clarity or Kendo UI to name a few. Such libraries provide common reusable components such as tabs, date pickers, collapsible menus, and much more. Still, there’s always a time where we need something more customized and more adapted to the specific needs of our project.

Abstractions are a critical part of software development. While we developers often abstract too much, software would take exponentially more time to build today without abstractions. Few write their own code to store data these days. We use databases instead. The same goes for web servers. And HTTP libraries. And JSON encoders/decoders. Like anything though, we can have too much of a good thing.

HTTPS is common, but I’d never actually set it up with Node.js because I had always been using services like Cloudflare that configure it for you.

Digital media will account for 43.5% of this total ad spend (eMarketer 2018) and will surpass conventional advertising by 2021. With online browsers bombarded with more and more advertising the trick is to capture their limited attention with compelling ads.

My neck and shoulders have bothered me since high school. Nothing debilitating, but a constant soreness and dull ache. I’m not 100% sure why but certainly my work environment is a very likely candidate. My posture can be questionable and for the longest time, I didn’t give even the slightest thought to the ergonomics of my setup. I did grab a standing desk a couple of years back in the hopes it would help my back in some way.
