Four days ago I was reading a thread I did have interest in about hiring freezes at Google and Facebook, and there was a tangential thread, which was even more insightful, between the Linux maintainer for ext4 (the Linux filesystem probably 99% of Android devices use, and a high percentage of Linux servers too), and another Googler/Xoogler about whether the Google storage engineering team could make non-incremental contributions, and which contributions were worthwhile and which weren't ( https://news.ycombinator.com/item?id=32323734 ).
