This is a letter I wrote to Proletären, the newspaper of the Communist Party of Sweden (K). The letter was published in issue 15, 9-15 April 2026. I cannot find it among the letters at proletaren.se at the moment (2026-04-20) and have therefore decided to also publish it here …
Detta är en insändare som jag skrev till Proletären, Kommunistiska Partiets (K) tidning. Insändaren publicerades i nummer 15, 9-15 april 2026. Jag hittar den inte bland insändare på proletaren.se just nu (2026-04-20) och har därför beslutat att även publicera den här på bloggen. Jag har även passat på att …
Recently Robin Hahnel posted the following article on the Participatory Economy Project's blog: Labor Time Accounting: A Postmortem . In this article Hahnel publishes some of his thoughts on the value theories of the classical political economists Adam Smith, David Ricardo and Karl Marx. He also talks about some contemporary political …

Recently it struck me that it might be useful to have a model of how the supply of final goods impacts final demand in an in-kind economy that doesn't regulate demand using means of payment. In other words, how does one balance supply and demand when the former induces the …
Podcasten Aurora är en samhällsanalyserande podd i historiematerialistisk tradition som ges ut av Föreningen Aurora . Detta avsnitt handlade om marknadssocialism.

Även Patrik Witkowsky:s …
Back in November, a friend of mine, my neighbor and his father in law took on the task of butchering a half moose that I got the opportunity to buy from the hunting team. The butchered carcass weighed 106 kg with practically no fat on it, because it was a …
This year I participated in my second moose hunt. This post documents my experiences with it, and some statistics. Like last time, dead animals ahead. Preparations Antennas Last year I was donated several marine VHF antennas from my younger brother, which just so happen to also work great for the …

Your browser does not support the video tag :( Went shooting with some friends last Wednesday. One of them brought his Polish WBP AK-47. I decided to try it out. Fun! Sweden removed the ridiculous ban on "military looking" firearms for hunting last year, so all semi-automatics are now OK for …
In order to effect control of any system we must first have data on that system. A planned economy, such as I've been writing about for the last few years, is synonymous with economic coordination in kind. For such coordination to not be completely arbitrary, to devolve into subjectivist nonsense …

In this post I will make the argument that error control (feedback) is not sufficient for good planning and that feedforward control is indispensable for good planning. To understand my motivation around this it is necessary to take a detour and talk about co-simulation, cyberphysical systems and my work on …
Last year I participated in my first ever moose hunt. This post documents my experience of it. Being a huge nerd I have also collected some statistics around it as a labour process. For readers who are unaware, the moose hunt in Sweden is something nearly religious. Life in rural …
Yesterday I finally got around to adding support for Debian 12 (Bookworm) and Ubuntu 23.10 (Mantic Minotaur) to FmiGo . A bug that caused one test to hang put me off doing this for a while. After a bunch of printf() debugging the bug turned out to be some kind …

Leone recently asked me about the parser for the game Workers & Resources: Soviet Republic that I wrote about in the post Mixed integer planning . It is licensed under the AGPL and available here: workers_and_resources on GitHub . Overview What the program does is parse the building definition files for all the …
I recently got an email from Leone of the econophysics Discord channel fame, asking for the code used in the post Planning complexity for model economies . I've been meaning to publish it for quite a while, and this was as good an excuse as any to add license stuff and …
In the previous posts Feasibility is optimal and On self-concordant convergence I have made the case that seeking centrality may be better than trying to optimize on some objective function. The reason for this is two-fold: there is uncertainty in the data that make up the constraints seeking centrality gives …
In the post Feasibility is optimal I suggested introducing a new barrier function to guarantee faster convergence towards the analytical center of a polytope. This turns out to be unnecessary or even detrimental, and in this post I will get into why. This post also presents a potentially new result …
Elossa is a podcast run by Elokapina , the Finnish section of Extinction Rebellion. We talk about planning, its history and especially how planning relates to the climate struggle. We also talk about the Swedish government's inability to deal with the situation. Regarding XR, I am skeptical of their methods, mostly …

In this post I have documented my efforts to get libreboot running on a pair of Lenovo ThinkPad T420's that I found in Umeå Hackerspace . The motivation is that I needed a new laptop, the ThinkPads were there, but they didn't support the SSD in my current laptop. I could …

In this post I will critique some points I have made in favor of optimality. Examples can be seen here and here . In the literature and present discourse on calculation in kind there is much debate around optimization. Leonid Kantorovich's "plan rays" is the start of this discussion as far …

Due to various compounding personal reasons I was not able to winterize my house in time this year. Usually I do this some time in November, before much snow has fallen so it is still accessible by car. It is a process that involves draining the water system and setting …
Lately I've been thinking of ways to perform "dress rehearsals" for a future democratic planned economy. As I have said on here before, it is important that planning penetrates down to the shop floor and into all communities, that all workers are able to directly engage in formulating the one …

In working on a future post I noticed my annoyance at Marx' use of the prime ( ′ ) symbol for the "rates" of various things, such as s ′ = s / v for the rate of exploitation. The mathematician in me doesn't like this since ′ is often used for derivatives. For example when dealing …
Three days ago I pushed support for Ubuntu 22.04 LTS (Jammy Jellyfish) to FmiGo . This has been sitting on my disk for a month or two and I finally got around to testing, cleaning it up and pushing it. This post is mostly a shameless ploy to get more …
I noticed just now that I don't have a link to the FmiGo website on this site, so I took the opportunity to update the landing page with a mention of the project. Me and Claude would like to see it picked up by someone, or perhaps a continuation of …
I recently learned of the GoBiGas project , an experimental gasification plant constructed by Göteborg Energi operated between 2014-2018 and mothballed since then. The idea is to turn biomass in the form of wood pellets and bark into methane (CH 4 ) at a rate of 20 MW (0.55 m³/s …

In this post I will look at how large linear programs we can expect to be solvable on a modern computer cluster. I will only consider linear programs related to economic planning, meaning programs that are very sparse. I will be using the local supercomputer center HPC2N and its Kebnekaise …
Recently I have been thinking about vertically integrated values. This has led me to some interesting observations which I will present in this post. If you don't know what vertical integration is in the context of political economy, it is the value added to some good not just when it …
Lately I've been wanting better ways of burning electricity in my house to keep the basement above freezing in winter. The cost of electricity isn't high enough to justify investing in a heat pump, but I want to do something better with the electricity than just turning it into heat …
Today I switched to blahtexml and MathML for the LaTeX equations on here. Before this equations were implemented via SVG files rendered by Markdown-LaTeX . The generated SVG was then inlined by base64 encoding. To get the rendering right, fonts had to be embedded into each base64'd SVG file. This meant …
In the first post in this series I made the point that while linear programming gets us quite far in planning, it cannot deal with the non-linearities which exist in real economies. In order to get a feeling for how difficult this actually is, I've been dipping my toes into …
The battery for my electric bike was recently stolen. To try and save some money I've been looking at building a replacement battery from some 18650 cells I have laying around. As part of this I thought I should document my findings on the blog. Hopefully it helps someone. The …
