Dear all

Dear all
Do you find my tutorials and nixcraft ( https://www.cyberciti.biz/ ) site useful? Please consider supporting it especially if you use ad-blocker. It is hard to keep the site running when so many people block ads. nixCraft is a single man indie operation and online since 2002. I had started this site for sharing my knowledge and documenting my experience as a sysadmin. Over last 15 years site grown a lot. I was able to fund nixCraft for a while with my job and savings.

I have written about Linux, Unix, FreeBSD, OpenBSD, Sysadmin and FOSS-related tutorials for many years. I have written over 5100+ tutorials and long blog posts. Apart from posts, I regularly reply tech support emails and moderate comments here. nixCraft has become a 40+ hour/week job for me. I want to nixCraft to grown more for a long time. It is time to see if it is possible to be a self-employed writer in the open source and Linux. By supporting me, you are going to keep the www.cyberciti.biz website alive.

You can choose from several options to support nixCraft:

  1. Patreon (Recommended option and you can pledge any amount you want from $1 to $as_per_your_wish)
  2. PayPal (one time donation)
  3. Bitcoin address: 1F8jsWqRuhND7LgmJ9F7QzwPBp4PS2tkRR

I am sure most *nix sysadmins or Linux user were helped at least once or many times by my nixCraft (https://www.cyberciti.biz). I needs your support, too. Thanks for any help you can offer if you decide to, and thanks for being a reader!
