## VIPNIX TUNING - System and Network Optimization for High Performance
##
## This file adjusts Linux kernel parameters to maximize performance on 10 Gbps networks,
## reduce packet retransmissions, and improve efficiency on high-load servers.
## Focused on local networks with low latency (1–5 ms), such as connections between Linux servers and macOS clients.
## Values are optimized to minimize packet loss, prioritize low latency, and maximize throughput.
# Increases the maximum number of events that inotify can monitor simultaneously.
# Useful for applications that monitor many files (e.g., file servers, backup tools).

Activate MS Office 2019/2016 for macOS - Microsoft_Office_2019_VL_Serializer

Office 2019 above

Note that Office2019 DO NOT support activate via simple copy/paste plist license file which is the simplest way to activate Office 2016. Fortunately, you can also use the VL Serializer tool, just install Office 2019 and Serializer, then run Serializer to activate.
