Show Notes

Hello and welcome to Sustain! The podcast where we talk about sustaining open source for the long haul. We are super excited to have two guests today, Sarah Gran and Josh Aas, who both work for ISRG, the Internet Security Research Group which consists of three projects: Let’s Encrypt, Divvi Up, and Prossimo. Sarah is a VP of Communication and fundraising for ISRG, and Josh is the Executive Director at ISRG. They are both working on Prossimo to bring memory safe code to critical digital infrastructure, which they will explain more in depth today. We also learn about some other projects they are investing in this year, and Sarah and Josh share some positive things they’re really excited about happening in 2022 with Prossimo. Go ahead and download this episode now to find out more!

Quotes

[00:04:05] “We just like to do a lot research about what we’re doing. We’re not a throw it at the wall and see what sticks organization.”

[00:12:05] “From my perspective in communications and fundraising, I think this is a great moment for us to help people understand that memory safety isn’t at the crux of Log4j.”

[00:14:31] “Rising tides raises all ships.”

[00:25:27] “We have a huge amount of history that tells us C++ code is not safe.”

[00:29:25] “I really hope that ten years from now, the number one web server is not written in C, that cannot happen, we can’t allow that to happen. Popular web servers written in C need to go.”

[00:36:37] “We can have a plan to boot OpenSSL off the internet. That’s a dream of mine and I think that’s an achievable goal.”
