The private bpftrace repository has just been made public, which is big news for DTrace fans. Created by Alastair Robertson , bpftrace is an open source high-level tracing front-end that lets you analyze systems in custom ways. It's shaping up to be a DTrace version 2.0: more capable, and built from the ground up for the modern era of the eBPF virtual machine. eBPF (extended Berkeley Packet Filter) is in the Linux kernel and is the new hotness in systems engineering.

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.

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.

There's good news and bad news. The bad news is I'm out sick so there's won't be a post this week. The good news? There will be that much more for next week! Bored? There are a lot of past issues of Stuff the Internet Says to keep you company.

There are a number of options for generating ID values for your tables. In this post, Alexey Mikotkin of Devart explores your choices for generating identifiers with a look at auto_increment, triggers, UUID and sequences. AUTO_INCREMENT Frequently, we happen to need to fill tables with unique identifiers. Naturally, the first example of such identifiers is PRIMARY KEY data.

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.

Google created Kubernetes to help developers better manage their containerized applications across clusters. Although a beta version was released in 2014, the first stable release of Kubernetes was just made available in September 2018. The following Kubernetes tutorial will cover the basic architecture and uses for this popular new tool. The Need for Containerization Today’s internet users don’t tolerate downtime, so developers have had to find ways to perform maintenance and update

This post complements the previous best practice guides this time with the focus on MySQL and MariaDB and achieving top levels of performance with the HammerDB MySQL TPC-C test. As with the previous guides as an Intel employee (#IAMINTEL) the examples are taken from a MySQL 8 on Linux on Intel system and the approach is the same for whatever system you are testing although some of the settings you see may be different.
