Service design leadership can be the responsibility of one person, or many, but it takes a whole organisation to improve a service over time, and crucially, make sure it stays that way.  To be able to have a good services in our organisation, we need service literacy

The visual way to analyse multidimensional data

Algorithms? Datamining? Brainrot? You don’t need those things to have a social network. As we knew back in the BBS days, long before anyone coined the phrase “social network”, all…

Systems Approach: Networks have changed profoundly, except for the parts that haven’t

The immense complexity of the climate makes it impossible to model accurately. Instead we must use uncertainty to our advantage

MIT Associate Professor Phillip Isola studies the ways in which intelligent machines “think” and perceive the world, in an effort to ensure AI is safely and effectively integrated into human society.

We manage the build pipeline that delivers Quip and Slack Canvas’s backend. A year ago, we were chasing exciting ideas to help engineers ship better code, faster. But we had one huge problem: builds took 60 minutes. With a build that slow, the whole pipeline gets less agile, and feedback doesn’t come to engineers until…

There are two competing forces in IT, and they are at play during the GenAI era as much as they have ever been during prior eras in the datacenter. One is

Dave Winer, OG blogger, podcaster, developed first apps in many categories. Old enough to know better. It's even worse than it appears.

Researchers from Peking University say their resistive random-access memory chip may be capable of speeds 1,000 faster than the Nvidia H100 and AMD Vega 20 GPUs.

We’ll be honest. If you had told us a few decades ago we’d teach computers to do what we want, it would work some of the time, and you wouldn’t really be able to explain or predic…

In Mark Bowden's book "Black Hawk Down," he notes that young soldiers repeatedly describe the shocking surreality of combat as "like being in a movie." As the book covers events that occurred in 1993, these soldiers have no other frame of reference. The soldier of today grew up in a

What is a Merkle tree? Why and how does Bitcoin use Merkle trees?

Sometimes when you’re making a PCB that you plan on programming over USB, but you only plan on plugging in a couple of times, it would be nice to make that connection without another BOM item…

This document gives the theory behind SPKI certificates and ACLs without going into technical detail about those structures or their uses. This memo defines an Experimental Protocol for the Internet community.

The SPKI Working Group first established a list of things one might want to do with certificates (attached at the end of this document), and then summarized that list of desires into requirements. This document presents that summary of requirements. This memo defines an Experimental Protocol for the Internet community.
