Teaching A Billion People To Code: How Jupyterlite Is Scaling The Impossible

Picture half a cardinal French precocious schoolhouse students learning mathematics and programming successful their individual browsers, each moving simultaneously from a azygous server.

For Sylvain Corlay, laminitis and CEO of QuantStack and personnel of nan Jupyter Steering Committee, this is not a pie-in-the-sky agelong goal. Corlay and his squad helped make it hap by building JupyterLite, a serverless distribution of JupyterLab moving wholly successful nan browser — kernel included, nary Docker necessary.

In this On nan Road section of The New Stack Makers, Corlay sat down pinch TNS Editor successful Chief Heather Joslyn astatine JupyterCon successful San Diego to talk really an “accidental startup” evolved into a 30-person squad pushing nan boundaries of what’s imaginable pinch browser-based computation and why that matters for nan early of worldwide method accessibility.

From Quant to Quantum Leap

QuantStack began successful 2016 arsenic what Corlay calls “almost an accidental startup” —  a one-person institution meant to support his activity arsenic a Jupyter halfway developer aft relocating from his occupation arsenic a quantitative expert astatine Bloomberg, successful New York, to France. The timing was perfect: Jupyter had exploded successful adoption, but astir maintainers were successful academia aliases ample corporations, creating immense request for consulting services.

Today, QuantStack is embedded successful aggregate kernel ecosystems beyond Jupyter, including Conda-Forge and Apache Arrow. But it’s JupyterLite (started by QuantStack squad personnel Jeremy Tuloup successful 2021) that represents nan organization’s astir wide-ranging mission.

“JupyterLite brings a level of scalability that Jupyter had ne'er had before,” Corlay said, pointing to nan French schoolhouse strategy deployment, called Capytale, arsenic impervious of concept: half a cardinal precocious schoolhouse students registered, complete 200,000 personification sessions per week, each fundamentally served from 1 server.

“All location is connected this server is simply a contented guidance strategy for nan school material, nan notebooks; everything other is served connected CDNs, and each of nan codification is executed successful nan extremity user’s browser,” he said. “You tin do elemental mathematics and Python programming successful nan browser very efficaciously — and you don’t request to spawn a Docker image successful nan unreality astatine standard for millions of users and require an elastic deployment of JupyterHub.”

The Billion-User Challenge

But half a cardinal users is conscionable nan beginning. Corlay’s imagination extends to countries pinch younger, larger populations.

“If you look astatine Nigeria, pinch a organization of 210 cardinal forecast to turn significantly, each of these kids are going to spell to schoolhouse and, because it’s nan 21st century, presumably study really to code,” he said. “It’s not reasonable to expect each personification convention to tally successful a Docker image somewhere. Nigeria astir apt doesn’t person infrastructure for that scale.”

JupyterLite’s low-tech approach, nevertheless — fundamentally a fixed page served from a CDN —  makes it feasible, and connected a world scale. “I really deliberation that we are connected to thing that could beryllium utilized to thatch programming to a cardinal people,” he said.

Making that imagination into reality, though, requires addressing challenges beyond axenic compute: gathering afloat accessibility standards for users pinch disabilities, real-time collaboration and expanding QuantStack’s unfastened root Emscripten-Forge package distribution to supply much packages for browser-based execution. It’s activity that firm clients don’t typically fund, requiring grants and instauration support.

Check retired nan afloat section to perceive much astir QuantStack’s origins astatine Bloomberg, nan company’s sustainable maturation philosophy, and hints astir an upcoming announcement astir nan convergence of “all of nan things that group from various parts of nan stack person worked on,” into thing Corlay describes arsenic “a ample crossover thing” that’s worthy staying tuned for.
