China’s credit crisis is worsening: New bank loans in China dropped -1.83 trillion yuan in 2025, or -10%, to 16.27 trillion yuan, the lowest since 2018. This marks their 2nd consecutive annual decline. China has been in an extended credit slowdown since early 2023, with the economy trapped in a deflationary spiral. Weakness has been driven by sluggish demand from borrowers, as weak consumer confidence and declining business investment have eroded appetite for new debt. China's 2008 moment is now.
The concept of neural pruning was presented to me in a very personal way, but after some initial shock, it looks awesome, so, since Blue Sky seems to be taking off, time for a social net neural pruning! Unfollow me, let's meet on the other social net, lemme go on doing my part.

This was a fantastic experience, in previous KR editions I watched the auctions as something like a noble effort. But this is not just noble, its required, its part of being a citizen of the world, doing what you think should be done, talking the talk, walking the walk. Do it.
Excellent wrap-up for this year's #Linux #perf_tools GSoC work: lore.kernel.org/all/CAH0uvohVu… Thanks a lot to @howardchu_ for the excellent work, having a BTF enabled 'perf trace' was something we really wanted for a long time, everything should land on Linux v6.12!

Igrejas são isentas de IPTU; livrarias não. É só um sintoma, talvez o menor. As últimas livrarias resistem na inóspita paisagem da cidade, tomada por comerciantes da fé, farmácias e bunkers pra quem tem muito dinheiro. O tempo pobre e a livraria pobre fundem-se no mesmo impasse
