A good Kubernetes setup makes the life of developers a lot easier and gives them time to focus on delivering business value. In this article, I will share the most important things you need to run a Kubernetes stack in production.

This article is a part of a series on io_uring Series introduction Part 1: Introduction to io_uring. In this article we create cat_uring based on the raw io_uring interface and cat_liburing, built on the higher level liburing. Part 2: Queuing multiple operations: We develop a file copying program, cp_liburing leveraging multiple requests with io_uring. Part… Continue reading io_uring By Example: Part 3 – A Web Server with io_uring

The OWASP Top 10 is the reference standard for the most critical web application security risks. Adopting the OWASP Top 10 is perhaps the most effective first step towards changing your software development culture focused on producing secure code.

How We Used GitHub PRs In A Trunk-Based, Continuous Deployment Development Team

What’s the shortest URL for which content is served on the internet? There are quite a few single-letter second-level domains that are used in very short URLs, such as Google’s http://g.co or Facebook’s https://m.me. But we can go shorter than this: there’s nothing stopping TLD registry operators serving A records at the apexes of their TLD zones. For example, if Verisign (the operator of the com TLD registry) wished, they could add an A record at the apex of the com TLD zone – com would then resolve to that IP, and your browser would connect to that IP when you visited https://com.

The adoption of CI/CD tools has made delivering new features to customers faster than ever. A far cry from the weeks-long code freezes and everlasting pipeline stabilization sessions that my team commonly referred to as integration hell. But yesterday’s solutions have exposed the next big challenge for today’s developers; actually getting code merged.

Absent a time machine, telling others how to avoid my mistakes is the best I can do.

We are building a distributed file system for your SQLite databases. Kinda weird, huh?

An open source Python 3 (CPython = 3.10.0) interpreter written in Rust 🐍 😱 🤘

As adoption of CI systems and processes becomes more prevalent, organizations opt for a CI/CD architecture which combines SaaS-based source control management systems (like GitHub or GitLab) with an internal, self-hosted CI solution (e.g. Jenkins, TeamCity). Many organizations using such architectures allow these CI systems to receive webhook events from the SaaS source control vendors, for the simple purpose of triggering pipeline jobs.

Oso Cloud’s Policy builder is an interactive tool that allows you to identify and select all the authorization patterns that fit your use case.

We are continuing our saga of CPU vs. GPU articles comparing the most common data-processing toolkits, and this time it will be about tabular data. Specifically, we will compare frameworks with Pandas-like Python interfaces on a dataset often used to compare SQL Databases. TLDR: Use Arrow to parse large datasets and split it in batches to process via CuDF 15x faster! If you are looking for a broader overview of the general topic - my recent PyData talk on “Accelerated Data-Science Libraries” was just published on YouTube.

We are excited to announce our team will be traveling to Amsterdam for The Things Conference on September 22nd-23rd, where Arduino will be among select exhibitors. The Things Conference is the world’s largest conference about LoRaWAN®, bringing together the industry’s major players contributing to this technology’s development in a two-day deep dive dedicated to making […]

The traditional mechanism for launching a program in a new process on Unix systems—forking and execing—has been with us for decades, but it is not really the most efficient of operations. Various alternatives have been tried along the way but have not supplanted the traditional approach. A new mechanism created by Josh Triplett adds process creation to the io_uring asynchronous I/O API and shows great promise; he came to the 2022 Linux Plumbers Conference (LPC) to introduce io_uring_spawn.
