System Architecture

It seems that all the cool companies are doing cross-region geo-routing for applications today. Many of them will label this as edge. For someone like myself edge usually means something different like having actual devices at sea, in the air, on a cell tower, in a Tesla, etc but if you are coming from the CDN world that translates to having multiple POPs (point of presence) spread throughout the world where you can host typically static sites (like javascript, css, etc.) closer to the end-user.

Anyone building consumer facing apps, be it mobile or web, has spent time looking at different options for authentication and not just the…

A system dynamics model, properly considered, is just an analogy dressed up in a bit of formalism.

A simple and powerful framework for ironing out confusing code.

I wondered how GPT-3 might do on the following problem: given a partially-connected graph, find a path between two nodes, or determine that no path exists. I wrote some code to automate generating …

BEM — Block Element Modifier is a methodology, that helps you to achieve reusable components and code sharing in the front-end.

Since its inception, the idea of utility CSS has been met with both praise by some and disdain by others. Tailwind took utility CSS to the extreme, and so has been especially controversial. Those who love it will say... - "It is a relief not having to come up with unique cla…

It’s not about the gloves. The pointlessness of the white gloves is actually a big part of it. Good service meets expectations. It is the fulfillment of a promise to the customer. White glove…

Just as last week, one big topic stood out - The Merge - this time, we'll go through some exciting announcements in the tech world concerning Linux, databases, and ML models. But before all that, a few current world events will unfortunately permeate our Weekly.

Sorry, this is a bit of a rant. My preferred routing library for React has been Raviger for a while but recently I needed to figure out how…

SBOMs display a complete inventory of the application, including all open source components and vulnerabilities. Here's how to make one, using syft and grype.

Platforms provide golden paths, with recommended tools and best security practices built in, reducing cognitive load while preserving developer freedom.

In these modern IT days – where the rapidly-evolving environment stretches from the datacenter to the cloud and edge, with a range of hyperscale cloud

For better or worse, C is the lingua franca in the world of kernel engineering. The core logic of the Linux kernel is written entirely in C (with a bit of assembly), as are its drivers and modules. While C is rightfully celebrated for its powerful yet simple semantics, it is an older language that lacks many of the features present in modern languages such as Rust. The BPF subsystem, on the other hand, provides a programming environment that allows engineers to write programs that can run safely in kernel space. At the 2022 Linux Plumbers Conference in Dublin, Ireland, Alexei Starovoitov presented an overview of how BPF has evolved over the years to provide a new model for kernel programming.

In this installment of “Ask Adam,” Adam Savage answers two very important questions: When should you bother to refurb a tool vs. buying a new one and does he get sad when he has to repl…

A hash tree or Merkle tree is a tree in which every non-leaf node is labelled with the hash of the labels or values (in case of leaves) of its child nodes. Hash trees are useful because they allow efficient and secure verification of the contents of large data structures. Hash trees are used in the IPFS file system, BitTorrent protocol, Git, Bitcoin, Ethereum, and a number of NoSQL systems like Apache Cassandra and Riak. They are used for many kinds of verification, especially of large chunks of data.

Performing I/O concurrently is one of asyncio's superpowers (if not its main superpower). This is accomplished, directly or indirectly (through helpers like asyncio.gather), by the creation and use of asyncio tasks. Even if you've never created an asyncio task yourself or called gather, you've used them because every

Zeek (formerly Bro) is the world’s leading platform for network security monitoring. Flexible, open source, and powered by defenders.

What is Bro IDS (Zeek)? Thinking about Bro as an IDS alone doesn’t accurately describe the breadth of its capabilities. Let's break down a more effective description.
