Mosh (mobile shell) is a gift from the Gods(tm). Anyone with spotty internet or wireless connection has suffered the pain of a lost SSH session. Sure, one can fire up screen (or tmux as the kids are using these days), but that's an extra step and you are still using the SSH protocol.

I'm not here to tout the benefits of Mosh, you came here to open it up in your firewall.

1. Create the following file as /etc/firewalld/services/mosh.xml
2. firewall-cmd --add-service=mosh --permanent
3. firewall-cmd --reload

If you tend to have a lot of sessions (not recommended), you can increase the ports, but the default should be fine for most applications.

Use ffmpeg to stream video from a dahua 4300s to a file or files

You can use ffmpeg to directly pull frames off of a dahua 4300s at full resolution. May be a good alternative to pricey dvrs which likely cannot record at full resolution, may not work with the camera, or are prohibitevly expensive

Simple Stream to file

Simple stream to file. Full resolution

ffmpeg -loglevel debug -rtsp_transport tcp -i "rtsp://admin:admin@198.175.207.61:554/live" \

-c copy -map 0 foo.mp4

Smart Caps Lock: Remap to Control AND Escape (Linux, Mac, Windows)

把 Caps Lock 變成智慧的 Control 以及 Escape ：

• 單獨輕按一下就是 Escape 。
• 若按下時同時按著其他鍵，就會是 Control 。

這應該是 Vim 和 Emacs 的最佳解了！(Emacs? Bash 的快捷鍵就是 Emacs 系列的)

• Send Escape if you tap Caps Lock alone.

library(shiny)
# Also uses parallel, shinyjs, tools

# Create a long-running task, executed in a forked process. (Doesn't work on Windows)
# 
# The return value is a promise-like object with three
# methods:
# - completed(): FALSE initially, then TRUE if the task succeeds,
#   fails, or is cancelled. Reactive, so when the state changes
#   any reactive readers will invalidate.
