Holberton School NHV recognized by US Senator as “Innovator of the Month”

We’re proud to announce that Holberton School New Haven, one of our US campuses based in Connecticut, has just been recognized by Senator Chris Murphy (D-Conn.) as “Murphy’s Innovator of the Month.”

“When I visited Holberton School New Haven, I was blown away by the way they’re transforming education.” -Senator Chris Murphy


In partnership with District Innovation and Venture Center (DIVC), a Connecticut based non-profit, we opened up our first remote US campus in New Haven. This campus addresses the shortage of qualified and diverse tech talent in Connecticut. Currently there are over 2,500 open software engineering jobs in the state, but in 2016 CT-based institutions only graduated around 430 students with Computer Science degrees. The training provided by Holberton helps to close this talent gap, and we are looking forward to our program’s graduates being a core part of Connecticut’s plan for future economic development.

This recognition validates that the hard work of our students and staff is making waves and inroads, while bringing economic growth and change to the local communities Holberton is a part of.

Introducing Holberton #1: Checker & You

So, serious question: Just how do you rapidly and accurately check over 10 million lines of code, submitted from students around the world, each and every week? On top of that, lets students know that they have made an error to fix before final submission, but does so in a way that helps the students learn and without giving the answer away?

For us, the answer is simple: Please meet Checker, our automated, scalable, accurate, and slightly devious testing tool, developed under the watchful eye of our CTO, Guillaume Salva.

Oh, and before we get too far, and in case you didn’t do the math, Checker analyzes, tracks, and scores over half a billion lines of code a year. If we were to print out that code to A4 paper then stack it up, we’d have a pile about 820m tall. Or, roughly, 3 Transamerica Pyramids stacked on top of each other.

Checker: Saving the environment from one impossibly tall stack of paper each year.

Who is Guillaume Salva?

Let’s pause and think a little bit: What kind of person would be best suited for developing the technological front-end and back-end at school that’s dedicated to upsetting the status quo of tech education? If you’re picturing a six foot tall, long-haired half-coder-half-professional-chef with a cryptic sense of humor, then you’re correct. While Guillaume hails from France (“From Normandy, born and raised with cream and butter; Viking style” is a response you might get from him), he currently resides in San Francisco, CA, and it’s here that he became one of the original tech employees for Holberton School. “Why not?”, was Guillaume’s response when asked why he started working for Holberton School, “It’s the only place where I could have a direct, personal impact with people and help them change their lives.”

And it was here at Holberton that he ran into a very specific requirement: How could we scale and automate the correction of all of our projects in all of the languages we teach, while also allowing for student testing of code before project deadlines? And thus, Checker was born.

Checker: The code that checks code

The Holberton community and student body is a collection of seriously dedicated people who are, in just a short period of time, mastering the skills that will land them their dream career. Through our peer learning and project-based curriculum, they’re expected to not only learn and master the fundamentals of programming, but also the fundamentals of self-driven learning. And with a first “year” that completes in just nine months, at the end of which students are expected to develop and launch a wholly working software product, rapid and consistent feedback is critical.

Enter Checker. This platform allows students to submit their code for review, and through our proprietary software’s well-programmed magic, will check the students work, and alert them to any errors that may exist. And Checker is thorough. Not only does it check for proper functioning of code created by students, but it can check for dozens of other critical supporting elements like proper code documentation, code styling, code efficiency, and more.

Checker being run on an early-curriculum Holberton School project

Now, what happens if Checker detects an error? Well, it would be too simple for our program to tell the students what the exact error is: We’re training programmers and developers, and for these professions, you have to learn how to find and fix the errors on your own. If students submit their code before the deadline, they will be alerted with how many detected errors they have in their code. From there, with our students working hard to get the highest score possible, they will be expected to review and find those errors by looking at the instructions of the assignment, looking for errors in their code, and other troubleshooting steps.

In this sense, it’s good to think of Checker like that awesome teacher or professor that never gave the answers away on the test, but helped give you the tools to find out the solution on your own.

To illustrate this point, let’s look at this scenario: Two students, running the same project, where they each get different errors. One student gets errors on Check 1 and Check 2, and the other gets errors on Check 3 and Check 4. Our students are smart; they know this, and we know this. So, if things were easy at Holberton, they could just huddle together, compare their code, find the errors by comparing their work, then both submitting for a perfect score. But, at Holberton, we’re not training people to be good at gaming the system: We’re teaching them how to program and solve problems.

So, in Checker, each individual student’s Check results are randomized. Two students who share the same error number in Checker are unlikely to have the same problem with their code. The students will still benefit from group code review sessions, but they can’t just treat their projects as comparison tests. They have to develop the skills they will use for the rest of their career as programmers, find the error in their code, and fix it. They can also coordinate with their cohort to help others who are running into roadblocks, but they can’t just copy their work off each other and breeze through our curriculum. After all, our students didn’t come to Holberton to learn what they could learn at any other school; they came to Holberton to challenge themselves and learn how to truly develop the skills that will help them with their dream career.

In the end, if there are standing Checker errors even after deadline submission, students are given the specific Checker alerts that matched their caught errors. This feedback is so they can learn and prepare for the next lesson, but until they complete the project, they will have to figure out the issue with nothing more than an alert that there’s a wrong answer.

Through Checker, our students are getting real-world training they need. Checker gives us the ability to automatically scale and support more students around the world, to reduce human error and oversight issues, and to help our students develop skills that they would not find at any other school. And when you’re chatting with a Holberton graduate, whether they’re someone you’re meeting at a conference, a coworker, or someone who you’re interviewing, make sure to ask them about their favorite Checker experience; the one where they worked the hardest to get that Check 0 (aka, no errors). While you might get a thousand-yard stare, you’ll definitely get a story full of trials, tribulations, and a fantastic coding success.


Checker and Holberton School

Checker, at its core, sums up Holberton School quite well. It’s a homegrown tool, built to address a problem, designed to give its users a qualitative real-world learning experience, and does so with efficiency and scalability in mind. Checker pressures students to check their own work, by themselves and in a group, without the ability to copy-paste someone else’s work to get the solution. It prompts the students to solve their own problems, and if they can’t get a perfect score on the assignment, it still gives them feedback to help them grow more. And with Holberton students ending up with great careers in some of the best tech companies around, we’d say it’s working pretty well.

Holberton School is expanding!

We are pleased to announce our latest campus in a location very near and dear to our hearts. Our connection with the new campus runs deep, show’s Holberton’s approach to a Blue Ocean development of technical education, and a new student body that we know is adept to taking on new challenges with a true “dive right in” mentality.

Introducing, Holberton School Atlantis!

We believe our next class of Hippokampoiers (“Seahorses” in French, and our school’s mascot) will be ready to dive deep and withstand the pressure of our accelerated program. Located approximately 150m underwater off the coast of Florida, our new campus will feature lots of tropical weather in an environment designed to foster cooperation and teamwork. Combined with our peer-learning based curriculum, we expect this next class to cooperate as well as sea otters holding hands

Our new campus provides many unique benefits to our students in Atlantis: The ability to get a top-tier technical education that supports long-term skill development, through our ISA students will be able to start their education with $0 upfront  tuition to start, and our new campus’ integration into nature will provide incredible health and stress relief benefits:

Welcome to the Mahi Mahi collaborative location.

“We’re proud to be partnering with Holberton School. We believe their approach to fostering student growth through collaboration and peer learning will help our students come together in a pod that will help Atlantis become the next hub for tech, despite what salt water does to electronics” – Marlin Lineman, Mayor of Atlantis

(Pictured: Students preparing for an immersive peer-learning session)


With this announcement, we’re looking forward to welcoming our next cohort this June around the world and under the sea. And through our education, we hope to help people prepare for their dream career in a tech bubble that will never burst.

Women in Tech – Simone Giertz

To inspire millions, it takes a rare combination of ability, timing, and vision. This, the human endeavor, has led to putting a human on the moon. Exploring the very limits of our universe. And, to make this:

As part of Women’s History Month, we want to celebrate both the historical innovators who made modern technology possible (We’re looking at you, Betty Holberton), and the women of today who are making a bit of modern history themselves. This week, we’re celebrating the work of none other than the Internet’s very own “Queen of Shitty Robots”, Simone Giertz.

Simone’s path to her being an international technological inspiration may not have followed the most traditional path: As a college dropout, she discovered her love of madcap engineering while interacting with local open-source hardware enthusiasts during her time at Hyper Island. Immersing herself with other creators, she embraced the “Learning by doing” mentality by jumping straight in with almost no prior robotics knowledge. Using her enthusiasm with a liberal amount of Googling, she taught herself from the ground-up how to build and program her first robots. In fact, while attempting to launch a children’s TV show in Sweden, she developed her Toothbrush Machine: a helmet that, at best, assaulted one’s face with a plastic toothbrush. While unfortunately the show was never picked up, her career as an innovator in horrible machines took off after she uploaded her creation to YouTube for all to see:

Simone combines a natural inquisitiveness, deadpan delivery, and desire to embrace the ridiculous was just what the internet needed. Rapidly what started off as her sharing the results of her tinkering with technology ended up with her headlining Reddit’s /r/all (often from posts in the aptly-named shittyrobots subreddit), being featured on shows like The Ellen Show and The Late Show with Stephen Colbert, and even one of the most enjoyable TED Talks in years.

Seriously, take a 12 minute pause break and watch her TED talk “Why You Should Make Useless Things” right now:

Not content to just make videos about machines that possibly only make your morning worse, she also documents her process for all of us to learn from, which are equal parts inspiring and amusing. This unique approach to curiosity and building whatever comes from it has led to joy, awkward laughter, and a newfound appreciation of tech among millions of fans across the internet.

Of course, beyond machines that assault with soup, she’s also launched a successfully backed Kickstarter to build The Everyday Calendar: A handsome device that helps everyone build good habits and get the grown up version of the Gold Star every day they achieve their personal, reasonable goal.

Simone’s path followed what we believe in most: The best way to develop new life skills is to jump in, learn with your peers, and to practically apply your learning throughout your self-driven education. And, most important of all, to never stop creating.

Recently, Simone announced that Brian, her brain tumor which she had previously sent on a vacation to Antarctica, has started to grow again. To this, we here at Holberton would like to say we’re rooting for you to successfully evict Brian for good, and that your videos, your enthusiasm for tech, and the very not-OSHA compliant robots that you bring into this world delight everyone here; student and staff alike.

Let’s celebrate Women in Technology

For Women’s History Month, we’d like to start with a huge Happy Birthday to the one and only Frances Elizabeth “Betty” Holberton, our namesake here at Holberton School and one of the first innovators in computer programming. As one of the six programmers who worked on ENIAC, the one of the first programmable, general purpose computers, she was literally at the forefront of computer programming, and continued to innovate throughout her entire professional career.

And being among the first, there were no teachers and she didn’t learn her trade by sitting in a classroom listening to lectures, but by diving in. She learning by observing and directly working with these early computer computational machines, and her innovations built the very framework of modern computing. This hands-on approach to learning by doing is what we try to embody today as we help train the next generation of tech leaders and innovators.

Betty Holberton entered software programming at the very beginning, and her inspiration as a tech pioneer continues today. In celebration of Women’s History Month and Betty Holberton’s birthday, we wanted to highlight why including more women in technology is a great thing for both the industry and society as a whole. So, we reached out to thought leaders, industry mentors, and the very people who have invested in Holberton School to ask them why they think including more women in tech is an important goal for us, and the broader tech industry as a whole, to pursue. And so without further ado, let’s celebrate Women in Tech and Women’s History Month with all of the people who believe in our vision of inclusion and diversity:


Neha Jain, Software Engineering Manager and winner of Top 10 Women in Cloud 2017


Kelvin Beachum, Professional player for the New York Jets and philanthropist

Shauntel Garvey, General Partner at Reach Capital:

Thank you Betty Holberton for the innovations your brought to tech, thank you to all the women leaders of today for their hard work and innovation, and good luck to the female innovators of tomorrow: We’re rooting for you and we know you’ll achieve greatness.
