Uncurled – everything I know and learned about running and maintaining Open Source projects for three decades.
This is me, doing a live English-speaking presentation/webinar on these topics that I cover in my book: Uncurled.
Date: Tuesday August 23, 2022
Time: 10: 00 UTC (12:00 CEST)
Where: over zoom [Sign up]
The plan is to record this session and make it available after the fact on YouTube. This post will be updated with a link to that once it exists.
Here’s the outlook on what I hope to be able to cover in a 40 minutes talk.
This will be followed by a Q&A-session with me answering any questions you might have. Feel most welcome and encouraged to submit your questions ahead of time if you already have some! (comment here, email me, comment or DM on Twitter, send a carrier pigeon, anything!)
I have not done this presentation before. I know the subject very intimately so I have no worries about that. The timing of the thing is what is going to be my bigger challenge I think. I aim for no more than 40 minutes of me blabbing.
As so many other events in these mysterious times, the foss-north conference went online-only and on March 30, 2020 I was honored to be included among the champion speakers at this lovely conference and I talked about how to “curl better” there.
The talk is a condensed run-through of how curl works and why, and then a look into how some of the more important HTTP oriented command line options work and how they’re supposed to be used.
As someone pointed out: I don’t do a lot of presentations about the curl tool. Maybe I should do more of these.
curl is widely used but still most users only use a very small subset of options or even just copy their command line from somewhere else. I think more users could learn to curl better. Below is the video of this talk.
Doing a talk to a potentially large audience in front of your laptop in completely silence and not seeing a single audience member is a challenge. No “contact” with the audience and no feel for if they’re all going to sleep or seem interested etc. Still I have the feeling that this is the year we all are going to do this many times and hopefully get better at it over time…
FOSDEM 2020 is over for this time and I had an awesome time in Brussels once again.
I brought a huge collection of stickers this year and I kept going back to the wolfSSL stand to refill the stash and it kept being emptied almost as fast. Hundreds of curl stickers were given away! The photo on the right shows my “sticker bag” as it looked before I left Sweden.
Lesson for next year: bring a larger amount of stickers! If you missed out on curl stickers, get in touch and I’ll do my best to satisfy your needs.
“HTTP/3 for everyone” was my single talk this FOSDEM. Just two days before the talk, I landed updated commits in curl’s git master branch for doing HTTP/3 up-to-date with the latest draft (-25). Very timely and I got to update the slide mentioning this.
As I talked HTTP/3 already last year in the Mozilla devroom, I also made sure to go through the slides I used then to compare and make sure I wouldn’t do too much of the same talk. But lots of things have changed and most of the content is updated and different this time around. Last year, literally hundreds of people were lining up outside wanting to get into room when the doors were closed. This year, I talked in the room Janson, which features 1415 seats. The biggest one on campus. It was pack full!
It is kind of an adrenaline rush to stand in front of such a wall of people. At one time in my talk I paused for a brief moment and then I felt I could almost hear the complete silence when a huge amount of attentive faces captured what I had to say.
I got a lot of positive feedback on the presentation. I also thought that my decision to not even try to take question in the big room was a correct and I ended up talking and discussing details behind the scene for a good while after my talk was done. Really fun!
The video is also available from the FOSDEM site in webm and mp4 formats.
If you want the slides only, run over to slideshare and view them.
I’m going to FOSDEM again in 2020, this will be my 11th consecutive year I’m travling to this awesome conference in Brussels, Belgium.
At this my 11th FOSDEM visit I will also deliver my 11th FOSDEM talk: “HTTP/3 for everyone“. It will happen at 16:00 Saturday the 1st of February 2020, in Janson, the largest room on the campus. (My third talk in the main track.)
For those who have seen me talk about HTTP/3 before, this talk will certainly have overlaps but I’m also always refreshing and improving slides and I update them as the process moves on, things changes and I get feedback. I spoke about HTTP/3 already at FODEM 2019 in the Mozilla devroom (at which time there was a looong line of people who tried, but couldn’t get a seat in the room) – but I think you’ll find that there’s enough changes and improvements in this talk to keep you entertained this year as well!
If you come to FOSDEM, don’t hesitate to come say hi and grab a curl sticker or two – I intend to bring and distribute plenty – and talk curl, HTTP and Internet transfers with me!
You will most likely find me at my talk, in the cafeteria area or at the wolfSSL stall. (DM me on twitter to pin me down! @bagder)
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!
In 2019 I did more public speaking than I’ve ever than before in a single year: 28 public appearances. More than 4,500 persons have seen my presentations live at both huge events (like 1,200 in the audience at FOSDEM 2019) but also some very small and up-close occasions. Many thousands more have also seen video recordings of some of the talks – my most viewed youtube talk of 2019 has been seen over 58,000 times. Do I need to say that it was about HTTP/3, a topic that was my most common one to talk about through-out the year? I suspect the desire to listen and learn more about that protocol version is far from saturated out there…
During the year I’ve done presentations in
Barcelona, Brussels, Copenhagen, Gothenburg, Mainz, Prague, Stockholm and Umeå.
I’ve did many in Stockholm, two in Copenhagen.
During the year I’ve done presentations in
Belgium, Czechia, Denmark, Germany, Spain and Sweden.
Most of my talks were held in Sweden. I did one streamed from my home office!
14 of these talks had a title that included “HTTP/3” (example)
9 talks had “curl” in the title (one of them also had HTTP/3 in it) (example)
In the afternoon of October 1st 2019, I had the pleasure of welcoming Linus Larsson and Jonas Lindkvist into my home in Huddinge, south of Stockholm, Sweden. My home is also my office as I work full-time from home. These two fine gentlemen work for Sweden’s largest morning newspaper, Dagens Nyheter, which boasts 850,000 daily readers.
Jonas took what felt like a hundred photos of me, most of them when I sit in my office chair at my regular desk where my primary development computers and environment are. As you can see in the two photos on this blog post. I will admit that I did minimize most of my regular Windows from the screens to that I wouldn’t accidentally reveal something personal or sensitive, but on the plus side is that if you pay close attention you can see my Simon Stålenhag desktop backgrounds better!
Me and Linus then sat down and talked. We talked about my background, how curl was created and how it has “taken off” to an extent I of course could never even dream about. Today, I estimate that curl runs in perhaps ten billion installations. A truly mind boggling – and humbling – number.
The interview/chat lasted for about an hour or so. I figured we had touched most relevant areas and Linus seemed content with the material and input he’d gotten from me. As this topic and article wasn’t really time sensitive or something that would have to be timed with something particular Linus explained that he didn’t know exactly when it would get published and it didn’t bother me. I figured it would be cool whenever!
On the morning of October 14 I collected the paper from my mailbox (because yes, I still do have a paper version newspaper arriving at my home every morning) and boom, I spotted an interesting little note in the lower right hand corner.
You can see the (Swedish-speaking) front-page blurb on the photo on the right.
The interesting timing this morning made it out so that this was the same morning I delivered a keynote at Castor Software Days at KTH in Stockholm titled “curl, a hobby project that conquered the world” (slides) – which by the way was received very well and I got a lot of positive comments and interesting conversations afterwards. And lots of people of course noticed the interestingly timed coincidence with the DN article!
The DN article reaches out to “ordinary” people in ways I’m not used to, so of course this made more of my non-techie friends suddenly realize a little more of what I do. I think it captures my “journey” and my approach to life and curl fairly well.
I’ll probably extend this blog post with links/photos of the actual DN articles at a later point once I feel I don’t risk undermining DN’s business by doing so.

I view myself as primarily a software developer. Perhaps secondary as someone who’s somewhat knowledgeable in networking and is participating in protocol development and discussions. I do not regularly proclaim myself to be a “speaker” or someone who’s even very good at talking in front of people.
Time to wake up and face reality? I’m slowly starting to realize that I’m actually doing more presentations than ever before in my life and I’m enjoying it.
Since October 2015 I’ve done 53 talks and presentations in front of audiences – in ten countries. That’s one presentation done every 25 days on average. (The start date of this count is a little random but it just happens that I started to keep a proper log then.) I’ve talked to huge audiences and to small. I done presentations that were appreciated and I’ve done some that were less successful.
My increased frequency in speaking engagements coincides with me starting to work full-time from home back in 2014. Going to places to speak is one way to get out of the house and see the “real world” a little bit and see what the real people are doing. And a chance to hang out with humans for a change. Besides, I only ever talk on topics that are dear to me and that I know intimately well so I rarely feel pressure when delivering them. 2014 – 2015 was also the time frame when HTTP/2 was being finalized and the general curiosity on that new protocol version helped me find opportunities back then.
Public speaking is like most other things: surprisingly enough, practice actually makes you better at it! I still have a lot to learn and improve, but speaking many times has for example made me better at figuring out roughly how long time I need to deliver a particular talk. It has taught me to “find myself” better when presenting and be more relaxed and the real me – no need to put up a facade of some kind or pretend. People like seeing that there’s a real person there.
I’m not even getting that terribly nervous before my talks anymore. I used to really get a raised pulse for the first 45 talks or so, but by doing it over and over and over I think the practice has made me more secure and more relaxed in my attitude to the audience and the topics. I think it has made me a slightly better presenter and it certainly makes me enjoy it more.
I’m not “a good presenter”. I can deliver a talk and I can do it with dignity and I think the audience is satisfied with me in most cases, but by watching actual good presenters talk I realize that I still have a long journey ahead of me. Of course, parts of the explanation is that, to connect with the beginning of this post, I’m a developer. I don’t talk for a living and I actually very rarely practice my presentations very much because I don’t feel I can spend that time.
Some of the things that are still difficult include:
The money issue. I actually am a developer and that’s what I do for a living. Taking time off the development to prepare a presentation, travel to a distant place, sacrifice my spare time for one or more days and communicating something interesting to an audience that demands and expects it to be both good and reasonably entertaining takes time away from that development. Getting travel and accommodation compensated is awesome but unfortunately not enough. I need to insist on getting paid for this. I frequently turn down speaking opportunities when they can’t pay me for my time.
Saying no. Oh my god do I have a hard time to do this. This year, I’ve been invited to so many different conferences and the invitations keep flying in. For every single received invitation, I get this warm and comfy feeling and I feel honored and humbled by the fact that someone actually wants me to come to their conference or gathering to talk. There’s the calendar problem: I can’t be in two places at once. Then I also can’t plan events too close to each other in time to avoid them holding up “real work” too much or to become too much of a nuisance to my family. Sometimes there’s also the financial dilemma: if I can’t get compensation, it gets tricky for me to do it, no matter how good the conference seems to be and the noble cause they’re working for.
Feedback. To determine what parts of the presentation that should be improved for the next time I speak of the same or similar topic, which parts should be removed and if something should be expanded, figuring what works and what doesn’t work is vital. For most talks I’ve done, there’s been no formal way to provide or receive this feedback, and for the small percentage that had a formal feedback form or a scoring system or similar, taking care of a bunch of distributed grades (for example “your talk was graded 4.2 on a scale between 1 and 5”) and random comments – either positive or negative – is really hard… I get the best feedback from close friends who dare to tell me the truth as it is.
Conforming to silly formats. Slightly different, but some places want me to send me my slides in, either a long time before the event (I’ve had people ask me to provide way over a week(!) before), or they dictate that the slides should be sent to them using Microsoft Powerpoint, PDF or some other silly format. I want to use my own preferred tools when designing presentations as I need to be able to reuse the material for more and future presentations. Sure, I can convert to other formats but that usually ruins formatting and design. Then a lot the time and sweat I put into making a fine and good-looking presentation is more or less discarded! Fortunately, most places let me plug in my laptop and everything is fine!
As a little service to potential audience members and conference organizers, I’m listing all my upcoming speaking engagements on a dedicated page on my web site:
I try to keep that page updated to reflect current reality. It also shows that some organizers are forward-planning waaaay in advance…
Invite someone like me to talk?
Here’s some advice on how to invite a speaker (like me) with style:
Ask well in advance (more than 2-3 months preferably, probably not more than 9). When I agree to a talk, others who ask for talks in close proximity to that date will get declined. I get a surprisingly large amount of invitations for events just a month into the future or so, and it rarely works for me to get those into my calendar in that time frame.
Do not assume for-free delivery. I think it is good tone of you to address the price/charge situation, if not in the first contact email at least in the following discussion. If you cannot pay, that’s also useful information to provide early.
If the time or duration of the talk you’d like is “unusual” (ie not 30-60 minutes) do spell that out early on.
Surprisingly often I get invited to talk without a specified topic or title. The inviter then expects me to present that. Since you contact me you clearly had some kind of vision of what a talk by me would entail, it would make my life easier if that vision was conveyed as it could certainly help me produce a talk subject that will work!
What I bring
To every presentation I do, I bring my laptop. It has HDMI and USB-C ports. I also carry a HDMI-to-VGA adapter for the few installations that still use the old “projector port”. Places that need something else than those ports tend to have their own converters already since they’re then used with equipment not being fitted for their requirements.
I always bring my own clicker (the “remote” with which I can advance to next slide). I never use the laser-pointer feature, but I like being able to move around on the stage and not have to stand close to the keyboard when I present.
I never create my presentations with video or sound in them, and I don’t do presentations that need Internet access. All this to simplify and to reduce the risk of problems.
I work hard on limiting the amount of text on each slide, but I also acknowledge that if a slide set should have value after-the-fact there needs to be a certain amount. I’m a fan of revealing the text or graphics step-by-step on the slides to avoid having half the audience reading ahead on the slide and not listening.
I’ve settled on 16:9 ratio for all presentations. Luckily, the remaining 4:3 projectors are now scarce.
I always make and bring a backup of my presentations in PDF format so that basically “any” computer could display that in case of emergency. Like if my laptop dies. As mentioned above, PDF is not an ideal format, but as a backup it works.
Yesterday, I had attracted audience enough to fill up the largest presentation room GOTO 10 has, which means about one hundred interested souls.
The subject of the day was HTTP/3. The event was filmed with a mevo camera and I captured the presentation directly from my laptop as well, and I then stitched together the two sources into this final version late last night. As you’ll notice, the sound isn’t awesome and the rest of the “production” isn’t exactly top notch either, but hey, I don’t think it matters too much.
