I have been looking for time to make a smooth and clean IRAF installation. That’s when it came, and I wanted to note here how I installed the latest version of IRAF (NOAO/IRAF community V2.16.1+ snapshot) from GitHub on my computer. I hope it will help someone. In fact, everything is explained in detail here, and I took advantage of it. The usual way is to install IRAF under the root directory “/iraf/iraf“, but I didn’t do that. So I didn’t need system administrator rights for installation. I installed directly under my $HOME directory. XQuartz and ds9 must be installed on your system. You can find them on their website: […]

In particular, I would prefer the FITS tables not images :). For this reason, I need a quick manipulation tool: CFITSIO – A FITS File Subroutine Library.

I have purchased Arduino MEGA 2560 with WCH340G chipset (Clone) from AliExpress. Then when i plugged in the Arduino to my Mac, i realized that neither Arduino IDE nor Atom IDE could make a connection from the USB serial. So, i googled the problem and i found a pure and simple solution here. Thank you for the clear instructions to Adrian Mihalko, who is the repository’s owner. Here are the warnings!
