Together with Linux Foundation Research, Hyperledger is conducting a survey to measure the market awareness and perceptions of Hyperledger and its projects relative to other blockchain platforms used in the technology industry, specifically identifying myths and misperceptions. Additionally, the survey seeks to help Hyperledger articulate the perceived time to production readiness for products and understand motivations for developers that both use and contribute to Hyperledger technologies.

  • Participants who complete the survey will receive a 50 percent discount on attendance to Hyperledger Global Forum, June 8-10, 2021
  • Please participate now; we intend to close the survey in early June. 
  • Privacy and confidentiality are important to us. Neither participant names, nor their company names, will be displayed in the final results. 
  • This survey should take no more than 20 minutes of your time.

Individuals in the USA who enroll in instructor-led training will be able to select from a variety of Linux-powered gifts from Best Buy. The options will change with time, but you should expect to be able to choose from things like:

Chomebooks
Android tablets
Fitness trackers
Smart watches
Smart speakers
And more!

After enrolling in your course, you will receive an email with a link where you’ll see all your options and can select the one that suits you best.

Sysadmins, as you know, wear a lot of different hats–meaning that sysadmins do a lot of different jobs and typically have ultimate power in all of them. The all-powerful root user account and its highly-protected password are good examples of that ultimate power. For those of you who perform work that falls under certain regulations, like those of Department of Defense (DoD) project, you may have to comply with guidelines from the National Institute of Standards and Technology (NIST) 800-171, which includes the separation of duties (Control 3.1.4).
