I've definitely been guilty of thinking about rendering on the web as a two-horse race. There is Server-Side Rendering (SSR, like this WordPress site is doing) and Client-Side Rendering (CSR, like a typical React app). Both are full of advantages and disadvantages. But, of course, the conversation is more nuanced. Just because an app is SSR doesn't mean it doesn't do dynamic JavaScript-powered things.

If you use React and need to display large lists of data efficiently , you may be familiar with react-virtualized. It's a windowing library by Brian Vaughn that renders only the items currently visible in a list (within a scrolling "viewport"). This means you don't need to pay the cost of thousands of rows of data being rendered at once.

FlameScope sub-second heatmap visualization. Less than a year ago, FlameScope was released as a proof of concept for a new profile visualization. Since then, it helped us, and many other users, to easily find and fix performance issues, and allowed us to see patterns that we had never noticed before in our profiles. As a tool, FlameScope was limited.

Almost two years ago I had written a tutorial around 2FA in a Node.js API with time-based one-time passwords. If you’re unfamiliar, two-factor authentication is becoming the norm, which it wasn’t necessarily back in 2017. If you’re managing user accounts in your web applications, it is critical that you offer your users a second factor of authentication to prevent phishing and malicious login attempts.

Occasionally I hear some chatter about performance budgets “not working.” And, to be fair, I have seen companies who adopt a budget and then are unable to make meaningful improvements towards that goal. Over time those ineffective budgets get pushed to the sideline where they accumulate dust before being forgotten about altogether. It’s not really about the performance budget, though.

In a bid to have web applications serve needs for different types of users, it’s likely that more code is required than it would be for one type of user so the app can handle and adapt to different scenarios and use cases, which lead to new features and functionalities. When this happens, it’s reasonable to expect the performance of an app to dwindle as the codebase grows.

Steve Souders, "JavaScript Dominates Browser CPU" : Ten years ago the network was the main bottleneck. Today, the main bottleneck is JavaScript. The amount of JavaScript on pages is growing rapidly (nearly 5x in the last 7 years). In order to keep pages rendering and feeling fast, we need to focus on JavaScript CPU time to reduce blocking the browser main thread.

In the previous post we introduced the Pool class of the multiprocessing module. In this post we continue on and introduce the Process class , which makes it possible to have direct control over individual processes. A process can be created by providing a target function and its input arguments to the Process constructor. The process can then be started with the start method and ended using the join method.

For this experiment I am using Postgres v11 on Linux 3.10 kernel. The goal was to see what gains can be made from using hugepages. I use the “built in” benchmark pgbench to run a simple set of queries. Since I am interested in only the gains from hugepages I chose to use the “-S” parameter to pgbench which means perform only the “select” statements.

Today’s blog post is about—you guessed it—more calendaring and scheduling stuff. This time I want to focus on one of the most unbelievably wasteful uses of time: time spent scheduling meetings. It’s a necessary evil, but can we at least optimize it, and get the lesser of the evils? Here’s the short version: I suggest we can avoid a ton of wasted time by preferring (in order) to keep calendars open, share your calendar’s free/busy, use meeting slot tools, or as

While working on the implementation of the MPI version of the STREAM benchmark, I realized that there were some subtleties in timing that could easily lead to inaccurate and/or misleading results.

A commonly altered setting is Maximum Degree of Parallelism (MAXDOP), which controls the maximum number of CPUs that can be used in executing a single task. For example, a large query may be broken up into different parts, with each part executing threads on separate CPUs. Such a query is known as a parallel query. […].

Having recently written quite a bit about email and communication, I want to turn to some of my backlog of thoughts on calendaring, scheduling, and meetings. I have learned a lot of techniques that I believe make me and my colleagues more effective and efficient, but there’s one simple tip that rules them all. It’s this: don’t schedule things back-to-back —leave gaps.
