This year, I’ve been working closely with the wonderful Coingaming team out in beautiful Tallinn. We’ve been working pretty hard on making their suite of online products much faster , and I’ve been the technical consultant leading the project. It’s been an incredibly fun and rewarding engagement, and we’ve made some real business- and customer-facing improvements.

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.

You can view the original article—H ow to implement consistent hashing efficiently —on Ably's blog. Ably’s realtime platform is distributed across more than 14 physical data centres and 100s of nodes. In order for us to ensure both load and data are distributed evenly and consistently across all our nodes, we use consistent hashing algorithms.

As is the case with many of the people who actually know what they’re talking about, I’ve come to shudder when I hear the word “Agile,” at least until I can figure whether the person who uttered the word actually knows what they’ve just said. More often than not, they don’t.

When I work with companies on improving their performance, we focus more and more on their long-tail of performance data. We look at histograms instead of any single slice of the pie to get a good composite picture of what the current state of affairs is. And for specific goals and budgets, we turn to the 90th or 95th percentile. For a long time, the average or median metrics were the default ones our industry zeroed in on, but they provide a distorted view of reality.

When looking to improve the performance and user experience of our sites we often start by looking at the network: What's the time to first byte? How many requests are we making and how long are they taking? What's blocking the browser from rendering my precious pixels? While these are entirely valid questions, over the last few years we've seen a growing number of web performance issues that are caused, not by the network, but by the browser's main thread getting clogged up by excessive CPU usa

MariaDB 10.3 is now generally available (10.3.7 was released GA on 2018-05-25). The article What’s New in MariaDB Server 10.3 by the MariaDB Corporation lists three key improvements in 10.3: temporal data processing, Oracle compatibility features, and purpose-built storage engines. Even if I am excited about MyRocks and curious on Spider, I am also very interested in less flashy but still very important changes that make running the database in production easier.

The benefits of modeling data as events as a mechanism to evolve our software systems. For as long as we’ve been talking about microservices, we’ve been talking about data. In fact, before we even had the word microservices in our lexicon, back when it was just good old-fashioned service-oriented architecture, we were talking about data: how to access it, where it lives, who “owns” it.

It’s probably obvious, but most modern applications crave data and in many of those scenarios, being able to visualize the data is a necessity. This is where charting and graphs become valuable within frontend applications. Having attractive charts in your application can make a world of difference and with a convenient library like Chart.js , it isn’t complicated.

I didn’t tune in for the WWDC stuff this year. I can remember being excited for that each year, eagerly anticipating what cool thing was coming next. However, for the past few years, I’ve found the announcements to be mostly mundane. This year, unless they were going to announce new and better laptops, I wasn’t overly excited. But when reading the recaps and tweets that followed the event, I was pretty intrigued to see the Apple Watch is now going to be able to support web cont

A co-worker introduced me to Craig Hanson and Pat Crain's performance mantras, which neatly summarize much of what we do in performance analysis and tuning. They are: **Performance mantras**. Don't do it. Do it, but don't do it again. Do it less. Do it later. Do it when they're not looking. Do it concurrently. Do it cheaper. These have inspired me to summarize another performance activity: evaluating benchmark accuracy.

When we released TiDB 2.0 in April, part of that announcement also included the release of TiSpark 1.0–an integral part of the TiDB platform that makes complex analytics on “fresh” transactional data possible. Since then, many people in the TiDB community have been asking for more information about TiSpark. In this post, I will explain the motivation, inner workings, and future roadmap of this project.

ccache , the compiler cache, is a fantastic way to speed up build times for C and C++ code that I previously recommended. Recently, I was playing around with trying to get it to speed up my Linux kernel builds, but wasn’t seeing any benefit. Usually when this happens with ccache, there’s something non-deterministic about the builds that prevents cache hits.

One of my younger family members came over to try to get inspired for his college future so we decided to work on a project together.

We decided to try to obtain the password to my wireless network password using the popular Aircrack-ng software.

In our continuing series on PPC optimization this time we look at optimizing text ad performance by tweaking ad titles. Technically called the "Business Name" field, we're calling it the ad title for brevity. By isolating higher performing ad text you can vary different parts of similar ads to see which variant performs better. This article shows that a small change to the ad title can make a big change in ad performance.

Also, Capacitor provides a high-quality API to work with native functions within your apps. For example, you can get access to the camera and it means you still get this access to every platform.

Modern applications often feature the use of data in many different languages. This is often true even of applications that only offer a user facing interface in a single language. Many users may, for example, need to enter names which, although using Latin characters, feature diacritics; in other cases, they may need to enter text which contains Chinese or Japanese characters.
