HTTP/3 builds on User Datagram Protocol (UDP), and is already being used by prominent internet companies such as Google and Facebook. If you’re using Chrome and connecting to a Google service, you’re probably already using QUIC.

Web scraping describes the various techniques employed in extracting data from websites. More often than not, this is done programmatically using tiny programs called spiders. However, web scraping offers insidious challenges and obstacles that might not be immediately obvious. One of them is issues with data validity.
The Original Sin of Rust async programming is making it multi-threaded by default. If premature optimization is the root of all evil, this is the mother of all premature optimizations, and it curses all your code with the unholy
Send + 'static, or worse yetSend + Sync + 'static, which just kills all the joy of actually writing Rust.

git snapcreates a commit that includes most local changes on a user- and machine-specific snapshots branch. It doesn't ask for a commit message. It also doesn't touch the working tree, saves and restores the index, and switches back to the branch that was checked out before runninggit snap. In other words, everything looks the same as before after runninggit snap, but your changes are safely stored by Git and can be pushed to a remote for redundancy or sharing. This is in contrast to stashes.

Rust does not provide the execution context required to execute Futures and Streams. This execution context is called a runtime. You can't run an async Rust program without a runtime.

A new iteration of HTTP, the protocol that powers the World Wide Web, is now with us. Designated HTTP/3, it’s been in development since 2018 and is currently in the Internet Draft stage of the Standards Track.

I’ve always found Go’s standard library very approachable to read. Parts of the standard library include concepts that are self-contained and do not require too much prior context to dive into. When I read that the sorting algorithm for Go has changed¹ to something called “pdqsort”, I thought it would be nice to go take a look and learn about it.

Our engineering team focuses on getting the maximum amount of information from the network while sending as little traffic as possible. This lean approach to network discovery is driven by our goal of being fast and safe for all networks. The more we can learn about a system from a single measurement, the less traffic we create and the quicker things run. In this post, I want to share how Rumble uses one of the most common network protocols to obtain a wealth of information about network-attached devices.

I was recently reading the first few chapters of Software Design for Flexibility (SDF). Doing so reminded of the duality between closures in Functional Programming (FP) and object instances in Object-Oriented Programming (OOP). When I'd heard it previously this connection had seemed tenuous at best and irrelevant at worst. However when I considered this duality this last time, I was able to internalize its significance.

In this post, we’ll cover the details of garbage collection in Python. First, we’ll review the basics about memory management and why we need garbage collection. Then we’ll look at how Python implements garbage collection. Finally, we’ll take a practical look at how you should think about garbage collection when writing your Python applications.

With pandas it is easy to read Excel files and convert the data into a DataFrame. Unfortunately Excel files in the real world are often poorly constructed. In those cases where the data is scattered across the worksheet, you may need to customize the way you read the data. This article will discuss how to use pandas and openpyxl to read these types of Excel files and cleanly convert the data to a DataFrame suitable for further analysis.

Five members of the Missing Persons Task Force investigate the mysterious disappearance of 17-year-old Evi. While unraveling the girl's troubled relationship with her parents, which leaves her father as one of the prime suspects, they discover that her life had recently taken a bizarre turn, with the teenager seen at several sex parties, receiving expensive gifts from a shadowy new friend. Was Evi the victim of a pimp, or did her father discover his daughter's double life and lose control?

I've now been using NixOS for one year. I use it to manage both my private PC and my laptop at work. Overall, it has been a great experience. I really appreciate the scale and control it brings to my digital life.
In May 2022, I stepped it up a notch by adding a third device running NixOS, namely a custom-built router! After a month of interspersed work I had successfully replaced my home network router.
In this blog post I'll go through why I embarked on this journey, how I did it, and lessons learned.

In web development, Hydration is a technique to add interactivity to server-rendered HTML. It’s a technique in which client-side JavaScript converts a static HTML web page into a dynamic web page by attaching event handlers to the HTML elements.
However, attaching event handlers to the Document Object Model (DOM) is not the most challenging or expensive part of hydration.
In this article, I’ll explain why I believe hydration is overhead. It’s not the solution; it’s a hack that consumes memory and slows down startup, especially on mobile. For the sake of this article, let’s define overhead as work that can be avoided and still leads to the same end result.
