This article explores the historical development of memory in computing, from the early innovations in storage to the evolution of modern memory technologies. It reflects on the forgotten milestones in memory history and their impact on current computing.

why Windows 95 setup goes through three operating systems: MS-DOS, Windows 3.1, and then Windows 95. Why not go from MS-DOS straight to Windows 95?

Border Gateway Protocol (BGP) is the routing protocol for the Internet. Much like the post office processing mail, BGP picks the most efficient routes for delivering Internet traffic. In this post, we’re exploring the intra-day shenanigans with an eye to finding some of the ridiculous things that go on out.

Why using /tmp to store file is a usually a bad idea.

Learn how CloudFlare use formal verification to mathematically prove properties about DNS addressing behavior, even when different systems (owned by different teams) at Cloudflare have contradictory views on which IP addresses should be returned.

This blog post from Micron explores the transformative role of DRAM (Dynamic Random Access Memory) in the evolution of technology. It highlights DRAM’s impact on everything from personal computing to cloud infrastructures and its continued importance in the development of modern devices.

After reading this article, you’ll learn about the techniques we use to analyze SQL query performance when dealing with millions of queries per day and monitoring hundreds of PostgreSQL servers.

The OpenStreetMap (OSM) database builds almost 750GB of location data from a single file download. OSM notoriously takes a full day to run. A fresh open street map load involves both a massive write process and large index builds. It is a great performance stress-test bulk load for any Postgres system. I use it to stress the latest PostgreSQL versions and state-of-the-art hardware. The stress test validates new tuning tricks and identifies performance regressions.

In this easy-to-follow tutorial, you will learn how to build your own voice assistant Siri with the LLAMA-3 AI Model.

In this series of articles, I would like to talk about Linux Page Cache. I believe that the following knowledge of the theory and tools is essential and crucial for every SRE. This understanding can help both in usual and routine everyday DevOps-like tasks and in emergency debugging and firefighting. Page Cache is often left unattended, and its better understanding leads to the following:

We’re going to build a tiny 1000 line implementation of a GraphRAG algorithm originally invented by Microsoft. I consistently hear people talk about this algorithm at meetups, but it appears there are several orders of magnitude of people talking about it than actually using it or implementing it. Likely because the reference implementation is enormous and rather complex. So let’s break it down and see if there’s any merit to the hype around this approach.
