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.

A look at the roles of architect and strategist, and how they help develop successful technology strategies for business. There are two jobs in the world that people want to do the most while knowing the least about: architect and strategist. I should start by saying this section does not offer a treatise on how to do architecture. 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
Measuring Performance With Server Timing. Measuring Performance With Server Timing. Drew McLellan. 2018-10-30T03:40:14+02:00. 2019-04-29T18:34:58+00:00. When undertaking any sort of performance optimisation work, one of the very first things we learn is that before you can improve performance you must first measure it. Without being able to measure the speed at which something is working, we can’t tell if the changes being made are improving the performance, having no effect, or even making thin

Over the last decade, flagship processors from Intel and AMD have been eking out only marginal cross-generational single threaded (ST) performance gains. Instead, the focus has been on boosting aggregate performance by increasing core count. While throughput performance is important, especially in data-centers, single threaded performance remains a pivotal metric for a large swath of application domains (HPC, Finance etc.).
As lists are the raw material of strategy and technology architecture, MECE list-making is one of the most useful tools you can have in your tool box. MECE, pronounced "mee-see," is a tool created by the leading business strategy firm McKinsey. It stands for "mutually exclusive, collectively exhaustive," and dictates the relation of the content, but not the format, of your lists.
Some time ago, a customer had a performance issue with an internal process. He was comparing, finding, and reporting the rows that were different between two tables. This is simple if you use a LEFT JOIN and an IS NULL comparison over the second table in the WHERE clause, but what if the column could be null? That is why he used UNION, GROUP BY and a HAVING clauses, which resulted in poor performance.
When it comes to CSS, there are always new tools being introduced to help us transform styles in a more fast and efficient manner. In 2013, PostCSS was released but it wasn’t until mid-2015 when a lot of buzz really started to take place in the development community around PostCSS. Today, in 2018, PostCSS is still widely used in the development community and the project itself is still actively maintained by a large community of contributors.

If you’re like me, you thought you’d try to build a cross-platform desktop application using the very popular Electron framework as well as the very popular Vue.js JavaScript framework. At first glance it might seem as easy as defining an Electron configuration, but in reality, a little more needs to be done when using Webpack to build the project.
Thanks to its reliable performance, extensive documentation and dedicated user community, PHP is one of the preferred server-side scripting language of many web developers. Consequently, there are so many free and premium PHP tools available online that it’s difficult for developers to determine which ones are worthwhile.

Windows has long had a reputation for slow file operations and slow process creation. Have you ever wanted to make these operations even slower? This weeks’ blog post covers a technique you can use to make process creation on Windows grow slower over time (with no limit), in a way that will be untraceable for most users! And, of course, this post will also cover how to detect and avoid this problem.
Typically, when we modify a program, we’d like to run it to verify our changes. Before booting a compiled Linux kernel image on actual hardware, it can save us time and potential headache to do a quick boot in a virtual machine like QEMU. as a sanity check. If your kernel boots in QEMU, it’s not a guarantee it will boot on metal, but it is a quick assurance that the kernel image is not completely busted.

Grey box testing is when the tester has a partial understanding of the internal structure in the system under test. Grey box testing is a process for debugging software applications by making an input through the front-end, and verifying the data on the back-end. We’ve talked about the difference between black box and white box testing before, so lets look at grey box testing in a little more detail.
In the context of providing managed WordPress hosting services, at Presslabs we operate with lots of small to medium-sized databases, in a DB-per-service model, as we call it. The workloads are mostly reads, so we need to efficiently scale that. The MySQL® asynchronous replication model fits the bill very well, allowing us to scale horizontally from one server—with the obvious availability pitfalls—to tens of nodes.
If you’re using Amazon S3 for a CDN, it’s possible to serve compressed, gzipped files from an Amazon S3 bucket, though there are a few extra steps beyond the standard process of serving compressed files from your own web server.

For Percona Live Europe, I’ll be presenting the tutorial Elasticsearch 101 alongside my colleagues and fellow presenters from ObjectRocket Alex Cercel, DBA, and Mihai Aldoiu, Data Engineer. Here’s a brief overview of our tutorial. Elasticsearch® is well known as a highly scalable search engine that stores data in a structure optimized for language based searches but its capabilities and use cases don’t stop there.
I’m a big fan of automated testing. The math just works out. Why spend hours running a series of test cases when a computer can do it in seconds. With benefits like this, my zeal for automated testing can make it seem like I think that all testing should be automated. However, this couldn’t be farther from the truth. There is little room in software development for pure rote manual testing, but that’s not the only reason to manually test software.
