Meta's CacheLib Sees New Release After Two Year Hiatus For Helping With High DRAM Prices

Back in 2021 Facebook open-sourced CacheLib as a new caching engine. Back in 2021 it was done to help scale services with non-volatile memory caching to offset increasing DRAM costs at the time.

Based on that, the SFC has created the baltobu project aimed at reverse-engineering and reimplementing the Bambu code while also hosting the Orca Slicer fork. Bambu has behaved badly for years and made multiple, provably false public statements regarding the AGPLv3 and its requirements. The recent aggressive behavior toward Paweł Jarczak was a last straw for us: we have decided to launch a multi-pronged effort that will assist consumers and users in the short-term, and also work toward a long-term strategy to improve the software right to repair for
