Every agent tool stores memory in its own shape, and every week someone builds another one. None of them can read the others. Observability had the same problem until OpenTelemetry gave everyone one data model to share. A tour of today's memory formats, the proposals that already exist, and what a shared spec could…
Let’s say you’re creating a CLI tool which has to display syntax highlighted source code. You begin by choosing some colors which look nice with your chosen terminal theme:
Memoryfields - a vastly simpler way to do agent memory
When a codebase is large and complex, it's risky to big changes. Here's a structured way to approach
Faster, more secure connections from space could one day make broadband on planes, ships and even remote roads as easy as turning on a light. The European Space Agency (ESA), Airbus Defence and Space, the Netherlands Organisation for Applied Scientific Research (TNO) and German payload manufacturer TESAT (as…
We previously noted that, while it's easier than ever to hit a particular quality bar by having coding agents use effective test techniques, software quality seems to be getting worse , indicating that whatever defaults developers are using may not work very well. Here, we test if simple instructions to agents to use…
Bedrock is a minimal, human-crafted starter-kit for Emacs, and today I’m pleased to announce that version 2.0 of Bedrock is available! This release requires Emacs 31, which came out in August 2026. If you are unable to upgrade Emacs that high, you should be able to remove some of the Emacs 31-specific config without…
We built Un-0, an image generator powered by a simulated system of coupled oscillators, an example of an emerging physical computing substrate. On ImageNet 64×64 it reaches FID 6.74, matching the quality of leading conventional image generation methods when they were first published. Weights, training, and ablation…
A decade ago this summer, at the Marine Biological Laboratory, Jocelyn Malamy watched jellyfish cells “walk” toward each other to close a wound for the first time. An associate professor in Molecular Genetics and Cell Biology at the University of Chicago, Malamy had received transparent, dime-sized medusae of the…
How to make infinite design variations using Perlin noise fields, a simple generative algorithm.
A new European Southern Observatory (ESO) study has found that current proposals to launch over 1.7 million satellites into orbit, including extremely bright ones, would have “devastating consequences for astronomy.” According to the study, no more than 100 000 faint satellites, below naked eye visibility, should…
python has 6 pre-declared "constants": True , False , None , __debug__ , Ellipsis (or equivalently ... ), and NotImplemented . but they all behave slightly differently, for some reason.
This isn't quite right , but it's the type of wrong that cites its sources and hides in the part you'd never think to fact check:
The current situation on the IT job market is hard. So you are lucky when a recruiter on LinkedIn reaches out to you having a suitable match for a new position based on your prior experience. It might not be what it seems at a first glance.
Cloudflare suffered a service outage on February 20, 2026. A subset of customers who use Cloudflare’s Bring Your Own IP (BYOIP) service saw their routes to the Internet withdrawn via Border Gateway Protocol (BGP).
With its new design, E Ink Kaleido 4 supports a broader range of digital content. Compared to the previous generation, E Ink Kaleido 4 doubles its color gamut volume to more than 40K, increases white reflectance by 15%, and improves contrast by 50%. Additionally, with the introduction of new algorithms, E Ink Kaleido…

Have you tried to explain lobbying to a non American unfamiliar with the concept?
The internet made coordination cheap and gave us the Bazaar. Coding agents make code cheap and are giving us sprawling, idiosyncratic software.
Every dataframe library ships with hundreds of operations. pandas alone has over 200 methods on a DataFrame. Is pivot different from melt? Is apply different from map? What about transform, agg, applymap, pipe? Some of these seem like the same operation wearing different hats. Others seem genuinely distinct. Without a…
I've spent the last month adding features and improving performance in z486_MiSTer , mostly working through games from the first half of the 1990s. Looking a few years ahead brought me to another change I wanted to explore: the arrival of 3D graphics cards.
A few years years ago the curl project signed up and became a CNA. This means that we are masters of and can allocate our own CVE identifiers. For any security problems within our territory, it is we who decides if the issue should get a CVE or not. No more bogus CVEs. 57 CVEs … Continue reading a CVE dispute →
I purchased a Matrix CoolRunner Rev D back in 2017. This little chip is called a glitcher and it’s a type of modchip. Its sole purpose, the reason it was designed, is to deliver a short pulse of energy (~ 100 nanoseconds) to an Xbox 360 Console.
I built a scriptable 3D game engine for the Nintendo DS so you can write and run games directly on the console itself. Written in C using libnds , it compiles to a 100KB .nds ROM that runs at 60 FPS . Features a touch-based code editor on the bottom screen and real-time 3D rendering on the top screen. Ships with a…
The Black Hole Mapper reaches a milestone with its first southern hemisphere optical observations, coordinated eROSITA X-ray identification, and multi-epoch tracking of accreting black holes across the universe.
History of the development of my windowed operating system for 32-bit Am29000 processors when I was age 18.
Update: I've since added multithreading and pushed astroz to 326M propagations/sec. Read the follow-up → I've spent the past month optimizing SGP4 propagat...
