🧵 Am updating once more my PLA Navy type & age structure graphs. Been doing these occasionally since ca. 2010 as they help me keep a grip on #PLAN fleet development; perhaps others find them useful too.

Starting this new round with the aircraft carriers. Let me know in case of typos/mistakes pls!

Long 🧵 which gives an excellent overview of the 🇫🇮 Finnish preparedness system, posted in March 2022 by @jmkorhonen.fi.
Many people have wondered how the Finns defend Finland today, so here's a very short introduction to modern Finnish defence policy - and a brief synopsis of how the Finnish military would probably fight if any hostile country decided to invade. 1/

The Navy would begin to lay minefields to close off the Finnish coast. Only selected sea lanes would be left open, guarded by warships and shore-based artillery and missile batteries. 22/

The Air Force would disperse to numerous small roadside bases - almost any straight stretch of a road would suffice in a pinch.

Troops would prepare to move to defend the normally demilitarized Åland islands. 23/

If the buildup continued to look hostile, more reservists would be called up. Together with civilian construction companies, they would begin to turn Finland into a hedgehog: prepared defensive positions and minefields would be constructed, and demolition charges installed. 21/

Less visible reminder of the total defence policy is the requirement to equip every bridge, overpass, tunnel, rock cut and similar construction with prepared demolition charge pits. Don't worry if you are in Finland, actual explosives would be installed only during a crisis.14/

The High North has been problematic for another reason: Soviet Union planned to "neutralize" northern Norway in case of war with NATO, and to do so, it required land access through Finnish (and Swedish) Lapland. (Source:...

St. Petersburg, Russia's number two city, is very close to Finnish border, and the Baltic seaway to Russia runs a gauntlet in the narrow Gulf of Finland. Whoever controls Finland and Estonia could theoretically bottle up the Russian maritime traffic at will. 4/

AIS-spoof-station WHISKEY 365 in Finland is offline.

It operated with a noteworthy 100% uptime for over a year. Oct 30 it started publishing anomalous data and caused a mass spoof event Nov 2.

Now offline since a few hours.

Guess: they were raided by FI authorities.

LLMs are now widely used in social science as stand-ins for humans—assuming they can produce realistic, human-like text

But... can they? We don’t actually know.

In our new study, we develop a Computational Turing Test.

And our findings are striking:
LLMs may be far less human-like than we think.🧵
Computational Turing Test Reveals Systematic Differences Between Human and AI Language
Large language models (LLMs) are increasingly used in the social sciences to simulate human behavior, based on the assumption that they can generate realistic, human-like text. Yet this assumption rem...

great thread on computationally (linguistic) analysing how not/human LLM output is.

turns out LLM generated text is 'easy' for computational linguistic analysis to spot.
The results were clear — and surprising.
Even short social media posts written by LLMs are readily distinguishable.

Our BERT-based classifier spots AI with 70–80% accuracy across X, Bluesky, and Reddit.

LLMs are much less human-like than they may seem.
