Franka Passing discusses the architectural shift of Duolingo’s 500+ backend services to Kubernetes. She explains the move toward GitOps with Argo CD, the transition to IPv6-only pods, and the "cellular architecture" used to isolate environments. She shares "reports from the trenches" on managing developer trust, navigating AWS rate limits, and productionizing early adopter services.
In his classic Programming Perl — affectionately known to a generation of technologists as "the Camel Book" — Larry Wall famously wrote of the three virtues of a programmer as laziness, impatience, and hubris:
If we’re going to talk about good software design, we have to talk about Laziness, Impatience, and Hubris, the basis of good software design. We’ve all fallen into the trap of using cut-and-paste when we should have defined a higher-level abstraction, if only just a loop or subroutine. To be sure, some folks have gone to the opposite extreme of defining ever-growing mounds of higher level abstractions when they should have used cut-and-paste. Generally, though, most of us need to think about using more abstraction rather than less.

Internet Protocol Version 8 (IPv8) is a managed network protocol suite that transforms how networks of every scale -- from home networks to the global internet -- are operated, secured, and monitored. Every manageable element in an IPv8 network is authorised via OAuth2 JWT tokens served from a local cache. Every service a device requires is delivered in a single DHCP8 lease response. Every packet transiting to the internet is validated at egress against a DNS8 lookup and a WHOIS8 registered active route. Network telemetry, authentication, name resolution, time synchronisation, access control, and translation are unified into a single coherent Zone Server platform. IPv4 is a proper subset of IPv8. An IPv8 address with the routing prefix field set to zero is an IPv4 address. No existing device, application, or network requires modification. The suite is 100% backward compatible. There is no flag day and no forced migration at any layer. IPv8 also resolves IPv4 address exhaustion. Each Autonomous System Number (ASN) holder receives 4,294,967,296 host addresses. The global routing table is structurally bounded at one entry per ASN.

The White House has announced that NASA will work with the Departments of Defense and Energy to put nuclear reactors in orbit and on the surface of the moon.
Some AI companies may be overvalued, but because they're VC-backed, failure won't disrupt the whole economy. The underlying technology also has value, making the AI boom unlike past bubbles.
The n8n n8mare: How threat actors are misusing AI workflow automation
Cisco Talos research has uncovered agentic AI workflow automation platform abuse in emails. Recently, we identified an increase in the number of emails that abuse n8n, one of these platforms, from as early as October 2025 through March 2026.
From Stuxnet to Operation Epic Fury: The China-Iran Intelligence Nexus - Domino Theory
Between 2010 and 2012, the CIA’s spy network in China experienced one of the worst intelligence breaches in modern history, leading Beijing to reportedly execute more than 30 U.S. sources. While the exact cause of the breach is still debated, one theory contends that Iran was at the center. At the time, Iran was investigating […]
