Google has released a new book: The Site Reliability Workbook — Practical Ways to Implement SRE. It's the second book in their SRE series. How is it different than the previous Site Reliability Engineering book? David Rensin, a SRE at Google, says : It's a whole new book. It's designed to sit next to the original on the bookshelf and for folks to bounce between them -- moving between principle and practice.

The other day, Brad dropped me a message asking me about the topic of getting to know a brand new (specifically CSS) codebase. The kind of codebase that no one person truly understands any more; the kind of codebase that’s had a dozen different contributors over just as many years; the kind of codebase that’s never had a full-scale refactor or overhaul, but that’s grown organically over time and changed with new techniques, styles, and trends.

One software vendor ask me, along with a few other performance professionals, to answer questions related to performance trends. But they changed their mind and never published it – leaving me to contemplate which particular thought they didn’t like… Well, here are their questions and my answers: What do you think is the “next big thing in performance” – or what should we all keep an eye out for in 2018?

Building data pipelines can offer strategic advantages to the business. It can be used to power new analytics, insight, and product features. Often companies underestimate the necessary effort and cost involved to build and maintain data pipelines. Data pipeline initiatives are generally unfinished projects. In this post, we will discuss why you should avoid building data pipelines in first place.

Accurate performance monitoring is crucial for Wayfair’s Storefront Engineering team. Each day we deploy hundreds of code changes to the web application for our customer-facing websites, and each change has the potential to impact performance for better or worse. For this reason, we carefully monitor KPIs such as page load. Read more.

The Westworld season finale made an interesting claim: humans are so simple and predictable they can be encoded by a 10,247-line algorithm. Small enough to fit in the pages of a thin virtual book. Perhaps my brain was already driven into a meta- fugal state by a torturous, Escher-like, time shifting plot line , but I did observe myself thinking— that could be true.

In the year since Google rolled out Lighthouse, it's safe to say that "Will you be adding Lighthouse scoring?" is one the most common questions we've fielded here at SpeedCurve HQ. And since Google cranked up the pressure on sites to deliver better mobile performance (or suffer the SEO consequences) earlier this month , we've been getting that question even more often.

I recently read a great article about procrastination. While the common viewpoint is that procrastination is a waste of time, it can also be a source of creativity. It reminds me of the classic advice when banging your head against a problem: take a break. Step away. Breathe. A year ago I started taking this advice a little further. If I am stuck with a problem, I put it off for at least a day.

Stress testing gives a measure of the reliability of a software system. Stress testing reveals how long a system can remain stable without crashing under a heavy, stressful load. In other words, we can say that stress testing discovers the breakpoint where a system starts to become unreliable. It can also be said that Stress testing is a form of Load testing for discovering the conditions that will cause a system will crash.

While I’ve developed applications that can be safely classified as vanilla native or core native using Java, I’ve spent most of my time developing cross platform applications for Android and iOS using frameworks such as Ionic Framework and NativeScript that support web technologies.

The assumption that engagement is somehow strongly correlated with performance is misplaced. Traditional engagement metrics such as satisfaction, happiness, well-being let alone cannot explain behaviours, actions and motivation of a high-performance team. Moreover, there is hardly any strong scientific evidence suggesting that there is a correlation between high-engagement and high-performance.

Windows provides an option for CreateFile to delete a file when the file is closed (FILE_FLAG_DELETE_ON_CLOSE.). Host Extension Handling. Linux does not expose such an option as part of the open syscall. Instead the host extension remembers that the open request was made with the FILE_FLAG_ON_DELETE option and after closing a file issues the remove syscall on your behalf.

Organizations of autonomous teams require a different set of behaviors than organizations that are run like a machine. People in a self-directed team form their own appreciations for what should be done, prioritize what will be done, and self-determine how it will be done. They are unencumbered by hierarchy, expected to communicate with anybody in the organization they need.

Unless this is an internal application, you’re probably going to want to publish the application to a marketplace like Google Play. The thing is, up until now, you’ve probably only been working with a debug build of your Android application and binary.

If you run a private WebPageTest instance on Amazon EC2, one of the choices you’ll have to make is whether to use Linux or Windows test agents. I had always been an advocate for the Windows AMIs – as most of the world runs Windows instead of Linux, I wanted the performance to represent what the majority sees. But last week I switched over to Linux test agents, and I don’t think I’ll ever go back to Windows – here’s why: 1.

There are thousands of ways we can shape the software systems we build and organise our teams around them. Yet there is no flowchart we can simply follow to find the optimal design. Sociotechnical systems are complex systems formed of complex systems. We have the unpredictable nature of markets. Consumer expectations are in a constant state of flux as new technological advancements arise and new competitors emerge, yet the goal is to continuously deliver products that satisfy market demand.

Application State Management and Data-Driven Decision Making. As the complexity of applications and systems increases, the size of the teams that work on these also increase. In these scenarios, having the system as a monolithic one inhibits the development team from being able to move forward at speed. This gave rise to the need for an approach that would allow independent functional teams to be able to deliver their functionality in its entirety with minimal (if any) dependency on other teams.

Three years ago when I would talk to engineers and technology leaders about the ideas around Chaos Engineering, only about a fifth of the audience had heard of the concept. Now when I mention the term, most hands in the room go up. This is due in large part to Netflix’s Chaos Monkey (and the rest of their “ Simian Army ”) as well as their Chaos Engineering team’s stories on the work they’ve done in the space and the benefits it’s produced.

My journey to and from work involves a small journey on a train. Without fail, there is this spot along the line where my network connection drops from a clear 4G signal to a 2G signal at best. I often kill time on the journey by surfing the web, and as you can imagine, a slow connection often stops bulky pages from loading altogether. It’s worth mentioning that around the world, not everyone is lucky enough to get such good connection speeds.

Can you imagine if you doubled your weight from 180 lbs to 360lbs in 3 years? You’d be a little embarrassed, right? Yet this is what has happened to web pages, and no one seems to be taking much action. Web pages have become massive since their minuscule proportions in the early 2000s. But what’s shocking is that despite our faster connection speeds, sometimes sites are loading even slower than they did back then.
