Turing Completeness of GNU find

Turing Completeness of GNU find: From mkdir-assisted Loops to Standalone Computation

The Unix command \texttt{find} is among the first commands taught to beginners, yet remains indispensable for experienced engineers. In this paper, we demonstrate that \texttt{find} possesses unexpected computational power, establishing three Turing completeness results using the GNU implementation (a standard in Linux distributions). (1) \texttt{find} + \texttt{mkdir} (a system that has only \texttt{find} and \texttt{mkdir}) is Turing complete: by encoding computational states as directory paths and using regex back-references to copy substrings, we simulate 2-tag systems. (2) GNU \texttt{find} 4.9.0+ alone is Turing complete: by reading and writing to files during traversal, we simulate a two-counter machine without \texttt{mkdir}. (3) \texttt{find} + \texttt{mkdir} without regex back-references is still Turing complete: by a trick of encoding regex patterns directly into directory names, we achieve the same power. These results place \texttt{find} among the ``surprisingly Turing-complete'' systems, highlighting the hidden complexity within seemingly simple standard utilities.

종종 사법부 썩었다 못믿겠다 법이랑 판례 학습 싹 시킨 AI 나오면 변호사 판사 대신할 수 있잖아!! 라고 하시는 분들이 있는데...

If you live in the #GortonAndDenton constituency and are thinking of voting #Labour (or #LibDem), please consider voting for the #GreenParty instead. It is very unlikely that Labour will win, and either way #KeirStarmer will be deemed to have failed.

The big risk, as always, is that the progressive parties (in which I generously include Labour) will split their vote, allowing the right-wing parties to win with a minority. Any centrist or left-winger shouldn't want #ReformUK to win with their parachuted-in proto-fascist.

Even if you don't care that much about politics, please use your vote and vote for the local #Green candidate #HannahSpencer, a plumber and an experienced councillor, who will properly represent the people of your constituency. It's safe to say she's not the kind of person who will be heading off to the Chagos Islands for a publicity stunt.

Gemini Pro: "evaluate the accuracy of the graphs on rgmii.org/history-gmi-1976-sec"

The "Second Gilded Age" is defined by the return to 19th-century levels of concentration. The graphs on the RGMII page are highly accurate representations of the "U-Curve" phenomenon in economics. They correctly identify 1976 as the year the U.S. economy structurally shifted from "broad-based growth" to "top-heavy concentration."

Based on the data from the Rural Guaranteed Minimum Income Initiative (RGMII) and the standard economic consensus (UC Berkeley, Federal Reserve), the graphs depicting 1976 as the start of the "Second Gilded Age" are historically accurate and statistically robust. The year 1976 is widely recognized by economists as the historical "inflection point"—the moment when the post-WWII era of shared prosperity (The Great Compression) ended and the modern era of widening inequality began. The "1976 Divergence" Verification The graphs likely presented on the RGMII site align with the "Gold Standard" of inequality data produced by economists Thomas Piketty, Emmanuel Saez, and Gabriel Zucman. The U-Shaped Curve (The "Piketty Line") The data accurately shows that 1976-1978 was the historical low point for wealth concentration. In 1976, the Top 1% held roughly 22% of national wealth. Since then, that share has nearly doubled to roughly 35-40%. The Great Decoupling (Wages vs. Productivity) A second key graph likely featured is the "Alligator Jaw." From 1948 to 1976, worker pay rose in lockstep with productivity. After 1976, the lines diverge: productivity kept rising, but typical worker pay stagnated. Data Audit: The 1976 Turning Point The specific claims associated with the "1976 Second Gilded Age" narrative are supported by Federal Reserve and CBO data. 1. The "Crossover" Phenomenon In 1976, the Middle Class held a significantly larger share of wealth than the Top 1%. Today, those lines have crossed. - 1976: The Top 0.1% owned 7% of household wealth. - Today: The Top 0.1% owns roughly 20%, nearly matching the bottom 90% combined. 2. Income Stagnation The graphs accurately depict that for the Bottom 50% of earners, real annual income has barely budged since the late 1970s, despite the economy tripling in size. - Since 1976: The average pre-tax income of the Top 1% has grown by over 300%. - Since 1976: The average pre-tax income of the Bottom 50% has grown by roughly 1% (after inflation). 3. The Source Credibility The RGMII (Rural Guaranteed Minimum Income Initiative) is a data-driven philanthropic organization (co-founded by tech entrepreneur Jeff Atwood). Their charts typically rely on: - Saez & Zucman (UC Berkeley): The primary source for "Distributional National Accounts." - EPI (Economic Policy Institute): The primary source for the Wage/Productivity gap.

A month ago there was a lot of buzz on the Fediverse about a new Mastodon server set up by prominent journalists: .

There was a rush of sign-ups: nearly 10,000 users in a couple of weeks. People new to the Fediverse, willing to try it out.

It's been hard to gauge how active it still is... so this morning I re-downloaded @IceCubesApp so I could browse their local timeline.

I've been liking and replying to recent posts. Just doing my little in making them feel seen and welcome 🤗
