I was invited to the podcast and talked to host Gavin Henry for over on hour.
What it’s been like to look after the curl project for the past 25 years. We talked about the history of cURL, libcurl, whether C was the right choice, portability, some key events in those 25 years, implementing protocols, why HTTP is not so simple, rust libs, the Polhem Prize, security issues, feature requests, random support requests, code on Mars, Apple OS adoption, cars stuck in production lines, Android OS, 8 week release cycles, release cycle joy, breakdown of bug types, 1000 committers, 250 command line options, user bases, determination, json, libSSH2, c-ares, HTTPbis, HTTP/2, QUIC, Mozilla, OpenSSL, wolfSSL, DNS, FTP, the cURL book, testing, CI/CD, favorite command line options that you might not know about, and making sure that you don’t give up on that idea or project you are working on.
It was a while since I last spoke Swedish on a podcast. I joined the friendly hosts Sebastian and Alex of the Trevlig Mjukvara (translates to something like “Nice Software”) podcast and we talked software development, open source, curl, Mozilla and a few other topics for an hour. I had a great time. (We had Jitsi act up on us more than once so we had to switch away from it mid-recording!)
curl is one of the most widely used software component in the world. It is over twenty years old and I am the founder and I still work as lead developer and head honcho. It works!
We talked about how I got into computers and open source in general. How curl started and about how it works to drive such a project, do releases and how to work on it as a full-time job. I am far from alone in this project – I’m just the captain of this ship with a large about of contributors onboard!
As a part of the promotion for this episode, I was photographed by a professional outside of my house and nearby on a very lovely summer’s evening. In a southern suburb of Stockholm, Sweden. So, not only does the GitHub material feature not previously seen images of me, since I’ve been given the photos I can now use them for various things going forward. Like for when I do presentations and organizers ask for photos etc.
The photos I’ve used most commonly up until this point are the ones a professional photographer took of me when I spoke at the Velocity conference in New York in 2015. Of course I’m eternally young, but for some reason those past six years are visible on me…
I’ve participated in some podcasts before. If my count is correct, this is the 19th time. See the whole list.
The new set of photos of me were shot by Evia Photos. One of them is used on the top of this page.
We have almost a tradition now, me and the duo Jerod and Adam of the Changelog podcast. We talk curl and related stuff every three years. Back in 2015 we started out in episode 153 and we did the second one in episode 299 in 2018.
Time flies and now we’re in 2021 and we did again “meet up” virtually and talked curl and related stuff for a while. curl is now 23 years old and I still run the project, a few things have changed since the last curl episode and I asked my twitter friends for what they wanted to know and I think we managed to get a whole bunch of such topics into the mix.
So, here’s the 2021 edition of Daniel on the Changelog podcast: episode 436.
2019 is special in my heart. 2019 was different than many other years to me in several ways. It was a great year! This is what 2019 was to me.
curl and wolfSSL
I quit Mozilla last year and in the beginning of the year I could announce that I joined wolfSSL. For the first time in my life I could actually work with curl on my day job. As the project turned 21 I had spent somewhere in the neighborhood of 15,000 unpaid spare time hours on it and now I could finally do it “for real”. It’s huge.
Just in November 2018 the name HTTP/3 was set and this year has been all about getting it ready. I was proud to land and promote HTTP/3 in curl just before the first browser (Chrome) announced their support. The standard is still in progress and we hope to see it ship not too long into next year.
Focusing on curl full time allows a different kind of focus. I’ve landed more commits in curl during 2019 than any other year going back all the way to 2005. We also reached 25,000 commits and 3,000 forks on github.
We’ve added HTTP/3, alt-svc, parallel transfers in the curl tool, tiny-curl, fixed hundreds of bugs and much, much more. Ten days before the end of the year, I’ve authored 57% (over 700) of all the commits done in curl during 2019.
We also (re)started our own curl Bug Bounty in 2019 together with Hackerone and paid over 1000 USD in rewards through-out the year. It was so successful we’re determined to raise the amounts significantly going into 2020.
I’ve done 28 talks in six countries. A crazy amount in front of a lot of people.
When Github had their Github Universe event in November and talked about their new sponsors program on stage (which I am part of, you can sponsor me) this huge quote of mine was shown on the big screen.
Maybe not media, but in no less than two Mr Robot episodes we could see curl commands in a TV show!
We talked curl of course but we also spent time talking about where HTTP/2 is and how QUIC is coming around and a little about why and how its UDP nature makes things a little different. If you’re into either curl or web transport, I hope you’ll find it interesting.
