Make keyboard on PC behave like Mac

PC keyboard has Alt key next to Space key while on Mac you have Command key next to it. On Mac you would do Command+Space to change language and Command+C, Command+V for Copy and Paste respectively. The easy and clean way to make PC keyboard having this behaviour is by using the free AutoHotKey tool. With the tool installed, you would create an .ahk file and run it to map the key combinations according to the content in the file. In my case, this is what I put in .ahk file

!c::Send, ^c
!v::Send, ^v
!space UP::Send #{Space}

!c is Alt+C which I will send ^c or Ctrl+C. The # is Windows key

Yulong D100 MkII Headphone Amp and Line Out Use

First, always use noise-filtered clean power supply. When you connect both line out connector (RCA) to your amp while at the same time plug in the headphone connector, I find that the sound through headphones will be distorted if the amp turned off. If you turn on the amp then the sound will be ok.  Disconnect the line connector from D100 is of course ok. But if you use both then this is a little bit annoying having to turn on the amp while you just want to listen via headphones or having to disconnect the RCA connector.

HikVision and AIS Port Forwarding

AIS Fiber ต้องลงทะเบียนที่ เพื่อทำ Port Forwarding

1. ลงทะเบียน จะได้เลข External Port มา 10 port
2. Config Port Forwarding บน Router ใช้เลข External Port ที่ได้จาก thddns
3. เหมือนได้เฉพาะ TCP/UDP แต่ RTSP ไม่ได้
4. HikVision ไม่มี http stream ต้องใช้ iVMS client connect ผ่าน Server Port ของกล้อง (Port 8000)
5. Forward External Port ไปที่ Port 8000 แล้ว Set iVMS ไปที่ External Port ที่ทำ Forward ไว้

Quick Apache Setup - Change localhost path on macSierra for Test Only

To quickly change the localhost path from default (/Library/WebServer/Documents) to your path and bypass all the permission problems

  • edit DocumentRoot in /private/etc/apache2/httpd.conf and set it to your path, both "DocumentRoot" and "Directory"
  • add the following lines
Options Indexes FollowSymLinks Multiviews
AllowOverride All

  • change User from _www to

This is for single machine and for test only as it will not be highly secure but it's a quick way for not having to do all the permission change on your test web directory.
