Ubuntu version history - Wikipedia
Ubuntu releases are made semiannually by Canonical Ltd, its developers, using the year and month of the release as a version number. The first Ubuntu release, for example, was Ubuntu 4.10 and was released on 20 October 2004. Consequently, version numbers for future versions are provisional; if the release is delayed until a different month than planned, the version number will change accordingly.

The Dual Nature of Events in Event-Driven Architecture
The Dual Nature of Events in Event-Driven Architecture
Given that events play such a central role in event-driven architecture, there’s an astonishing lack of agreement on what should be contained in an event. This may be rooted in the fact that, depending on your perspective, events fulfill different purposes.

Technology readiness level - Wikipedia
Technology readiness levels (TRLs) are a method for estimating the maturity of technologies during the acquisition phase of a program. TRLs enable consistent and uniform discussions of technical maturity across different types of technology. TRL is determined during a technology readiness assessment (TRA) that examines program concepts, technology requirements, and demonstrated technology capabilities. TRLs are based on a scale from 1 to 9 with 9 being the most mature technology.

Vector Databases Are the Wrong Abstraction
Vector Databases Are the Wrong Abstraction
Today’s vector databases disconnect embeddings from their source data. We should treat embeddings more like database indexes—here’s how.

Windows NT vs. Unix: A design comparison
NT is often touted as a "very advanced" operating system. Why is that? What made NT better than Unix, if anything? And is that still the case?

#11: Concurrency Is Not Parallelism
Parallelism can exist without concurrency, but concurrency can enable parallelism as it provides a structure to solve a problem with parts that may be parallelized.

How Cell-Based Architecture Enhances Modern Distributed Systems
How Cell-Based Architecture Enhances Modern Distributed Systems
Cell-based architecture has emerged as a response to many challenges associated with distributed systems. It employs the bulkhead pattern to isolate failures to a fraction of the affected infrastructure footprint and prevent widespread impact. Cells can also help organize large architectures into domain-bound deployment and delivery units, which provides essential sociotechnical benefits.

Channel capacity of a telegraph
Channel capacity of a telegraph
Claude Shannon's famous paper A Mathematical Theory of Communication [1] includes an example saying that the channel capacity of a telegraph is log2 W where W is the largest real root of the determinant equation Where in the world did that come from? I'll sketch where the equation above came from, but first let's find
