Since March 2000, CriticalMAS has been a one-man operation. Across the website, you will see links to products or services discussed in blog posts. Many of these products are affiliate links that help me earn money to pay for this site.

Support my other website It is a site dedicated to coffee education, which has been online since April 1999.


I am a big fan of Udemy and have purchased several courses. I found the quality to be higher than Lynda or Pluralsight. Use my Udemy link if you want to purchase a class. They often run sales where the price is below $15. Considering the depth of content it is a total bargain.

PayPal or BitCoin Donations

If you’d like to contribute to CriticalMAS with a small PayPal donation, that would be awesome!

I also have a BitCoin wallet.



Web Hosting

I have been through so many web hosts over the years. Most are terrible. Either they can’t handle the load, the servers go down, or their customer service sucks. I use SiteGround for this blog as well as my high traffic site It is the fastest and most stable host I’ve seen for WordPress and their service is the best.
