You may have heard about the world-changing potential of blockchains — the technology behind cryptocurrencies such as Bitcoin and Ethereum. But what are they exactly? And why are companies clamoring to use and develop blockchain technologies?

“It’s not too outlandish to think that in five years time, every Fortune 500 company and perhaps even the top 1,000 will have deployed a blockchain somewhere,” said Hyperledger Executive Director Brian Behlendorf, in a recent article on

In a free webinar to be held Dec. 1 at 10 a.m. Pacific, guest speaker Dan O’Prey, CMO of Digital Asset Holdings, will provide an overview of blockchain technology and the Hyperledger Project at The Linux Foundation.

Hyperledger is an umbrella project for software developer communities building open source blockchain and related technologies. It is a neutral, foundational community for participating companies such as IBM, Intel, Cisco, JPMorgan, Wells Fargo, the London Stock Exchange, Red Hat, and Swift to work together to develop the technology and address issues of code provenance, patent rights, standards, and policy.

In this webinar, Dan will cover:

  • The foundations of distributed ledger technologies, smart contracts, and other components that comprise the modern blockchain technology stack.

  • Why a new blockchain project was needed for business and what the main use cases and requirements for the technology are for commercial applications, as well as extending the overview on the history and projects in the Hyperledger umbrella and how you can get involved.

Let’s Encrypt was awarded a grant from The Ford Foundation as part of its efforts to financially support its growing operations. This is the first grant that has been awarded to the young nonprofit, a Linux Foundation project which provides free, automated and open SSL certificates to more than 13 million fully-qualified domain names (FQDNs). 

The grant will help Let’s Encrypt make several improvements, including increased capacity to issue and manage certificates. It also covers costs of work recently done to add support for Internationalized Domain Name certificates. 

“The people and organizations that Ford Foundation serves often find themselves on the short end of the stick when fighting for change using systems we take for granted, like the Internet,” Michael Brennan, Internet Freedom Program Officer at Ford Foundation, said. “Initiatives like Let’s Encrypt help ensure that all people have the opportunity to leverage the Internet as a force for change.”

We talked with Brennan and Josh Aas, Executive Director of Let’s Encrypt about what this grant means for the organization. What is it about Let’s Encrypt that is attractive to The Ford Foundation? 

Michael Brennan: The Ford Foundation believes that all people, especially those who are most marginalized and excluded, should have equal access to an open Internet, and enjoy legal, technical, and regulatory protections that promote transparency, equality, privacy, free expression, and access to knowledge. A system for acquiring digital certificates to enable HTTPS for websites is a fundamental piece of infrastructure towards this goal. As a free, automated and open certificate authority, Let’s Encrypt is a model for how the Web can be more accessible and open to all. What is the problem that Let’s Encrypt is trying to solve? 

Josh Aas: As the Web becomes more central to our everyday lives, more of our personal identities are revealed through unencrypted communications. The job of Let’s Encrypt is to help those who have not encrypted their communications, especially those who face a financial or technical barrier to doing so. Let’s Encrypt offers free domain validation (DV) certificates to people in every country in a highly automated way. Over 90% of the certificates we issue go to domains that were previously unencrypted or not otherwise not using publicly trusted certificates. How does Let’s Encrypt further the goals of The Ford Foundation? 

Michael Brennan: We think a lot about the digital infrastructure needs of the open Web. This is a massive area of exploration with numerous challenges, so how and where can the Ford Foundation make a meaningful impact? One of the ways we believe we can help is by supporting initiatives that broadly scale access to security and help introduce those efforts to civil society organizations fighting for social justice. Let’s Encrypt fits perfectly into this goal by both serving critical Web security needs of civil society organizations and doing so in a way that is massively scalable. From your perspective at The Ford Foundation, what population of people is Let’s Encrypt serving? 

Michael Brennan: The Internet Freedom team recently took on a trip to visit the Ford Foundation office in Johannesburg, South Africa. While we were there we met with a number of organizations leveraging the Internet to promote social justice. One of the organizations we met was building a tool to serve the needs of local communities. They were thrilled to hear we were supporting Let’s Encrypt because prior to its existence they could only afford to secure their production server, not their development or testing servers.

Let’s Encrypt is changing security on the Web on a massive scale so it can be easy to overlook small victories like this. The people and organizations that Ford Foundation serves often find themselves on the short end of the stick when fighting for change using systems we take for granted, like the Internet. Initiatives like Let’s Encrypt help ensure that all people have the opportunity to leverage the Internet as a force for change. What can Let’s Encrypt users expect as a result of this grant? 

Josh Aas: We will make several improvements through this grant, including our recently added support for Internationalized Domain Name certificates. We will also use these funds to increase capacity to keep up with the growing number of certificates we issue and manage. What other fundraising initiatives are you pursuing? 

Josh Aas: We run a pretty financially lean operation — next year, we expect to be managing certificates covering well over 20 million domains an operating cost of $2.9M. We have funding agreements in place with a number of sponsors, including Cisco, Akamai, OVH, Mozilla, Google Chrome, and Facebook. Some of those agreements are multi-year. These agreements provide a strong financial foundation but we will continue to seek new corporate sponsors and grant partners in order to meet our goals. We will also be running a crowdfunding campaign in November so individuals can contribute. How can people financially support Let’s Encrypt today? 

Josh Aas: We accept donations through PayPal. Any companies interested in sponsoring us can email us at Financial support is critical to our ability to operate, so we appreciate contributions of any size. How can developers and website admins get started with Let’s Encrypt?

Josh Aas: It’s designed to be pretty easy. In order to get a certificate, users need to demonstrate control over their domain. With Let’s Encrypt, you do this using software that uses the ACME protocol, which typically runs on your web host.

We have a Getting Started page with easy-to-follow instructions that should work for most people.

We have an active community forum that is very responsive in answering questions that come up during the install process.

Open source is the new normal for startups and large enterprises looking to stay competitive in the digital economy. That means that open source is now also a viable long-term career path.

“It is important to start thinking about the career road map, and the pathway that you can take and how Linux and open source in general can help you meet your career goals,” said Clyde Seepersad, general manager of training at The Linux Foundation, in a recent webinar.

Certification is one clear path with real career benefits. Forty-four percent of hiring managers in our recent 2016 Open Source Jobs Report said they’re more likely to hire certified candidates. And 76 percent of open source pros surveyed believe certifications lead to a career boost.

The Linux Foundation Certified System Administrator (LFCS) and Certified Engineer (LFCE) exams are great opportunities for sysadmins to polish and prove their skills. The exams are available online to anyone in the world at any time. They’re also performance based, working within a Linux server terminal and overseen by a proctor. Because the format is not multiple choice, even seasoned pros will need some preparation in order to avoid common mistakes and complete the exam within the time limit.

To help you prepare for the certification exam, and a long and successful sysadmin career, we’ve gathered some tips, below, from Linux Foundation certified sysadmins who have completed the LFCS or LFCE exams.

1. Practice

“Experience is key. Spin up a VM, take a fresh snapshot of it and go to work applying all the requirements of the exam in practice. When you feel you have satisfied all the exam topics thoroughly, apply that fresh snapshot to revert changes and begin again until it is second nature. Also, feel comfortable with man pages; they are your best friend when Google is not an option.”

Chris Van Horn, Linux Foundation Certified System Administrator (LFCS) and a “Debian guy.”

2. Give it time

“The best preparation is your experience. If you feel that you have enough experience with the topics required by the exam, you can give it a try. Otherwise, you have to work hard to get those skills.

Don’t think that in a short time you can learn everything.”

Dashamir Hoxha, LFCS, an Ubuntu user and open source contributor.

3. Learn how to use man pages

“If you haven’t already, get familiar with the man pages. Know what they are and how to use them efficiently.

No matter how much you study, you can’t learn everything, and if you could, you wouldn’t retain it all anyway. The man pages will fill in the gaps.”

William Brawner, LFCS, and Arch Linux user who plans to take the LFCE exam next.

4. Understand the material, don’t just memorize it

“Forget recipes, it’s not about memorization. Understand what are you doing by reading some books and documentation that give you a deep background of the tasks you’ll perform at the exam and in real life.

Imagine real problems and try to solve them.”

Francisco Tsao, LFCE, self-professed Debian fanboy and Fedora contributor.

5. The boring stuff is still important

“Do not rely on one book only! Study and practice…even the stuff that you find mundane.

A portion of the tasks are boring, but you cannot avoid them.”

George Doumas, LFCS, and a fan of Scientific Linux, openSUSE, and Linux Mint.

6. Follow the instructions


Jorge Tudela Gonzalez de Riancho

“For experienced professionals, I recommend that they prepare the environment for the exam, and follow the instructions. It’s not a difficult exam if you work daily with Linux.

On the other hand, for newcomers, apart from having a look to open/free resources, I just encourage them to set up a Linux environment at home and get their hands dirty!!”

Jorge Tudela Gonzalez de Riancho, LFCS, Debian user and Raspberry Pi enthusiast.

7. Have fun!


Gabriel Canepa
