The Shape of Context in Agentic Authorization

Mon Jul 6 10:04:00 2026

In agentic systems, the principal, action, and resource are often unknown until the moment an agent acts, and the context that governs the decision arrives as a flood of signals from many sources. This post looks at how that context takes shape, where each signal is actually consumed, and why a non-directed world of agents still needs decisions that humans can inspect and predict.

Activity Contexts in SquareTag

Mon Jan 28 11:31:00 2013

While knowing my location is a good thing, knowing what I want to do is even better. Until machines become sentient, SquareTags that record activity context is an excellent way to bridge the gap.

The Trends Driving KRL and Kynetx

Mon Apr 25 17:57:00 2011

In my last post, I outlined a few benefits that developers could gain from using KRL. Well and good, but so what? Are those benefits that matter? How do they relate to the other reasons programmers learn new languages like money and opportunity? In this post, I will talk about some of the big trends driving my thinking and informing the decisions around what KRL is and why it enables the abstractions that it does. There are three trends I'd like to examine: The rise of real-time data and the evented Web The rise of personal data and user-centricity

A Completely Connected World Depends on Loosely Coupled Architectures

Fri Feb 18 10:11:00 2011

This article from CNNMoney describes a completely connected world where not just every device, but literally every thing you own "will want to be your friend on the Facebook of things." At the Mobile World Congress in Barcelona, companies like IBM (IBM, Fortune 500), Qualcomm (QCOMM), AT&T (T, Fortune 500) and Ericsson showed off their vision of a not-too-distant future in which every item in your life, from your refrigerator to your fridge magnets, will soon connect to the Internet or communicate other Internet-connected gizmos. Here's how it would work: Electric devices like washing machines, thermostats and televisions will

Contextually Correlating Events: The Power of Emergent Behavior in Loosely Coupled Systems

Wed Jan 19 16:42:00 2011

One of the real powers of event-based programming is the ability to contextually correlate events. That's a pretty dense phrase. I'm writing this blog post to unpack it a little in my mind. Hopefully it will do you some good as well. Single events, like web:pageview, mail:received, or phone:inbound_call can be interesting. We've made money on Kynetx apps that rely exclusively on these kinds of primitive events. In spite of that, we can create even more interesting applications when we start to correlate one event with another. This is analogous to building Web applications. While there are plenty of

The Futility of Positively Identifying Commenters

Tue Sep 29 09:44:00 2009

Image by El Tipo Gráfico via Flickr A recent NY Times article discusses the Chinese order for Web sites to register and post comments using their true identities. Of course, in a totalitarian regime (are we calling China that these days?) identity is a tool that the state uses to control dissent and it's clear that's what's behind this. This article caught my attention because of the attention that SideWiki has been getting this week. John Gillmore said "The Net interprets censorship as damage and routes around it." SideWiki is an example of how what China's attempting is ultimately

Space-Time-Travel Data Changing the World Now

Fri Sep 11 08:03:00 2009

Jeff Jonas, who is one of the world's premiere data analysis experts writes: Mobile devices in America are generating something like 600 billion geo-spatially tagged transactions per day. Every call, text message, email and data transfer handled by your mobile device creates a transaction with your space-time coordinate (to roughly 60 meters accuracy if there are three cell towers in range), whether you have GPS or not. Got a Blackberry? Every few minutes, it sends a heartbeat, creating a transaction whether you are using the phone or not. If the device is GPS-enabled and you're using a location-based service

The Advent of Next Generation Browsing

Wed Feb 4 19:44:00 2009

Today I'm releasing the first of a series of white papers on Kynetx and what it's trying to accomplish: The Advent of Next Generation Browsing (PDF). I introduce the problem in the first few paragraphs like so: We are mired in a tangle of architectural legacies that make today's Web browsing experience uncomfortable, confusing, and tiresome for many users. In particular, the lack of Web site independent identity has hampered the ability of the browser to effectively intermediate the Web on the user's behalf. But change is coming and we are about to witness a significant improvement in the

Bring You Own Context

Fri Nov 28 12:20:00 2008

Om Malik writes about the recent terrorist attacks in India and the torrent of information on Twitter. He says: Despite the tremendous volume of information --- and its immediacy --- coming from Mumbai via Twitter, getting context about the situation has been a struggle. While a few people have been tweeting firsthand accounts, much of the information has been re-tweets or just rambling, reaction-based tweets. Maybe I was overcome with emotion, but the sheer volume of tweets and lack of clarity only fed my frustration with Twitter. (I'm sure it's the same kind of frustration people

Alex Russell on Comet: Beyond AJAX (ETech 2006)

Wed Mar 8 16:14:00 2006

Alex Russell, who works at JotSpot and did the DOJO Toolkit for JavaScript is talking about Comet and low latency data to and from browsers (slides). The subtitle is "after AJAX." The goal is responsiveness. AJAX gives you half the answer. AJAX is about me. Social applications are driven by others--the multiuser web. How do we send the datagrams that users make to each other. To any one user, the server represents the other users. Because the Web is a multiuser experience, single interaction updates aren't enough. Users in the same "space" need live updates of their own changes
