A July 4 Technical Reading List
For engineers who want more than fireworks this holiday, here is a short collection of recent deep-dives, ranging from the death of a legendary browser to the inner workings of CPU frequency scaling.
The Internet Explorer retirement post-mortem
With Internet Explorer officially reaching end-of-life, a new analysis looks back at its long reign and the transition to Microsoft Edge. The piece digs into bot traffic data to measure how many automated clients online still impersonate retired IE versions, offering a quirky look at the browser's lingering ghost in the network.
Live-patching the Linux kernel with eBPF
For those seeking a heavily technical read, this post walks through live-patching Linux kernel security vulnerabilities using an eBPF Linux Security Module. Expect full code samples, Makefiles, and a detailed look at applying critical fixes without a full reboot cycle.
Hertzbleed, thoroughly explained
If CPU-level side channels are your interest, a deep explainer on Hertzbleed breaks down how dynamic frequency scaling creates a measurable side channel that threatens cryptographic algorithms. The math is dense, but the payoff is a clear understanding of a nasty modern attack class.
Early Hints in the real world
The HTTP Early Hints standard promises faster page loads, but real-world data is what matters. A joint effort between Cloudflare, Google, and Shopify has produced performance analysis showing how much latency the feature actually saves in production environments.
Killing the CAPTCHA with Private Access Tokens
CAPTCHAs are widely disliked, and a new open standard aims to replace them. A technical breakdown of Private Access Tokens explains how the protocol lets a device prove it is operated by a human — without revealing any identifying information about that human. The post details the token handshake and how the new standard is being integrated into Apple platforms.
TCP tuning for high throughput, low latency
Finally, for network engineers, an in-depth look at TCP parameter optimization tackles the classic trade-off between high WAN throughput and responsiveness. The post covers specific kernel tunables, buffer sizing, and congestion control strategies for squeezed WAN links.
