While open source seems like a "no-brainer" for government use, it turns out that governments can be surprisingly resistant to using FOSS for various reasons. Federico González Waite spoke at SCALE 22x to recount his experiences working with and for the Mexican government. #opensource

Greg Kroah-Hartman has released three more stable kernels: 6.13.3, 6.12.14, and 6.6.78. There was a bit of confusion that resulted in the patch for CVE 2025-21687 getting applied twice — but that doesn't result in any problems for users of the kernel, just a bit of extra noise in the CVE database.
