Colossal computing

Mon, Jun 05, 2017

Chris DeJong 鈥91 grew up playing with stacks of computer punch cards. 鈥淲e used them for art supplies,鈥 he explained.

Today, DeJong is a technical lead/manager at Google, working in warehouse scale computing, helping to run some of the largest datacenters in the world.

In between, he graduated from Calvin with a history degree.

鈥淐alvin was the ideal place for me,鈥 said DeJong. 鈥淚 was a computer hobbyist with a strong interest in the humanities. I enjoyed history at Calvin, and I really appreciated studying the big-picture questions that the history department is so good at engaging students in.鈥

DeJong pictured himself as a humanities professor, so he continued his studies in history at the University of Rochester. 鈥淚 think I would have ended up at a place like Calvin, where a student like me received a lot of attention from some very qualified people.鈥

DeJong鈥檚 career journey shifted, though, when he realized that he was more passionate about technology and got involved in computer consulting to 鈥渉elp pay the bills.鈥

After working in computer software design in the Chicago area, he moved west, eventually landing in San Francisco, where in 2010 he began working for Google in cluster management.

Now he works in warehouse scale computing鈥攂asically, a large amount of square footage (equal to several football fields) filled with servers, racks and network gear operating as one datacenter. DeJong manages teams that work to keep all of those computers running.

Such massive computing is unique to Google and few other large companies. For example, Google handles 3.5 billion searches a day, or 2.3 million per second, in 146 languages.

鈥淭he system is designed to run massive services,鈥 said DeJong, 鈥渢hings like Web search, Gmail, the cloud, YouTube鈥攕ystems that require tens or hundreds of binaries on hundreds or thousands of machines.鈥

The swiftly moving world of computing presents a challenging aspect to DeJong鈥檚 job. 鈥淓verything is changing all the time. I never feel caught up. This is the only job in my life where I鈥檝e never been bored, and I never run out of things to do.鈥

Even for a person positioned in the midst of all of this technology, it鈥檚 astounding: 鈥淚鈥檓 amazed every day when I walk around one of the datacenters,鈥 said DeJong.

DeJong鈥檚 teams are responsible for ensuring that all of those computers work efficiently together, so that people can do everyday things like retrieve photos from the cloud, watch cat videos on YouTube and search for hotels in Africa.

鈥淔or me the biggest technology surprise was the phones; nothing in science fiction saw these phones coming,鈥 said DeJong. 鈥淪ince 2007, when the iPhone came out, the whole world is different. Everyone now carries a tiny computer. Ever since, there has been a huge emphasis on building software for these phones.鈥

Despite adding a master鈥檚 degree in computer science to his r茅sum茅, DeJong still credits Calvin history professors David Diephouse and Dale Van Kley, art history professor the late Charles Young, and communication arts and sciences professors Patricia Blom and Jim Korf for introducing him 鈥渢o a much bigger space, intellectually.鈥

鈥淐alvin was the perfect place for someone with a diversity of interests,鈥 said DeJong.

Besides majoring in history, DeJong was an 鈥渦nofficial鈥 philosophy minor, audited art history classes, performed in numerous plays and was one of the founders of River City Improv.

In fact, he still directs, performs and teaches improv with the Leela Theater Company in San Francisco. 鈥淏eing a teacher is really transformative,鈥 he said. 鈥淚 think that if I had stayed in teaching, I would have taught the history of technology.

鈥淭his industry is having a huge effect on history, and having a better understanding of it would do us all some good.鈥
