The content discusses testing the performance limits of a simple application setup to determine how many HTTP requests per second a single machine can handle. The architecture consists of a single instance of an application and database, all managed by an automated Python script. The application generates 1,250,000 random rows in a database table and includes a simple security feature requiring a secret key for all requests. Testing was conducted on four DigitalOcean machines, each with 2 CPUs and 2 GB of memory, over short and

After optimizing backend services, databases, and API responses, users still experience slow page loads due to excessive connection establishment times during peak traffic—specifically related to TLS handshake saturation. While many view TLS as minimal overhead, it involves significant CPU-intensive cryptographic operations performed by load balancers. Under normal conditions, a TLS handshake takes about 20-30ms, but during traffic peaks, it can spike to 5 seconds due to queues forming when new requests outpace the load balancer's fixed number

The content discusses a bug encountered in the netcode of Chocolate Quake where starting two clients on the same machine causes the second client to render the first client immobile, signified by an indicator resembling an unplugged Ethernet cable. While investigating, the author discovered various indicators within game files, including TURTLE and RAM. The TURTLE indicator appears when the framerate drops below 10 fps, likely intended for internal use by developers at id Software to identify performance issues. It can be togg

The content discusses a specialized monitoring device used in Department of Energy (DoE) facilities to prevent employees from accidentally bringing cell phones into secure areas. This device plays an audio message ("government cell phone detected") when it identifies a tag, despite most phones being personal devices. The text highlights the absurdity and inefficiency of using such an expensive, specialized system for a simple issue. The author expresses a fascination with obscure wireless networking protocols, mentioning RuBee, developed by Visible Assets Inc., founded by John

Cloudflare, a major CDN provider, experienced a significant outage that affected numerous popular apps and web services for several hours. The outage was triggered by a problematic configuration file that caused widespread failures across Cloudflare's operations. This incident highlights the growing centralization of the internet, as it increasingly relies on a few key providers, leading to vulnerabilities. The interruption impacted not only online services but also everyday activities, illustrating a lack of resilience in systems dependent on constant internet access. While the internet was initially designed for

The author describes their experiences during a "fixit week" at their organization, where around 45 software engineers halt regular work to focus solely on fixing small bugs and enhancing developer productivity. This quarterly event is marked by a unique set of rules: no bug should take longer than two days to fix, and the focus is on minor end-user issues. A points system and leaderboard add a competitive element, with rewards like T-shirts for various achievements. The author expresses a deep passion for improving products at both

The content discusses the capabilities of MacOS Tahoe, which can now generate SSH keys backed by the secure enclave, effectively replacing third-party solutions like Secretive. There is a shared library, `/usr/lib/ssh-keychain.dylib`, that has traditionally supported smartcard integration but now also implements the `SecurityKeyProvider` interface. This allows for direct loading of keys from the secure enclave and interaction with FIDO2 devices like Yubikeys. To create a secure enclave-backed key that requires

The article discusses the concept of technical debt, highlighting that it often stems from upstream commercial decisions that prioritize short-term gains over long-term architectural quality. While taking on technical debt can provide temporary benefits, consistently opting for immediate wins leads to rising operational costs, missed delivery deadlines, and team burnout. The author, drawing on his experience in engineering leadership, introduces the notion of "revenue debt," which captures the tension between appearing financially stable and dealing with increased operational complexities and risks. The article aims to provide

The speaker discusses their experience optimizing a RISC-V emulator to achieve an impressive performance of 550 million instructions per second through interpretation. They reflect on their journey in compiler development, particularly emphasizing the utility of two data structures: arenas and StringMaps. Arenas allow efficient bulk memory allocation, which is beneficial in compiler phases where memory isn't released incrementally. StringMaps facilitate efficient string management by using a hashmap for string indices, leading to reduced payloads and faster comparisons, akin to string interning. The

The article provides an overview of the floodfill algorithm, which is used for coloring regions within images. It explains the intuitive concept behind the algorithm, demonstrates its implementation in Python, and includes three example applications with interactive demos and code. By the end of the article, readers will be equipped to apply and modify the floodfill algorithm in their own projects. An interactive element allows users to click on an image to see how color fills the selected region, demonstrating the algorithm's behavior as it spreads color based on

The content outlines the creation of a sophisticated log collection agent for Linux that automatically discovers, monitors, and streams system logs to a distributed processing pipeline. Key features of the agent include a multi-source log discovery engine, real-time file monitoring system, structured log parsing and enrichment, efficient batching and transmission, and a web-based monitoring dashboard. Linux systems generate logs in various locations, and without an effective collection system, important events can be lost amid fragmented files. The proposed collector automatically identifies and monitors active log
