WEBVTT 00:00.000 --> 00:22.000 So, welcome to the next talk about free suing by Yost and yeah, have fun. 00:22.000 --> 00:27.000 All right, thank you for coming to my little talk here at Fostam. 00:27.000 --> 00:32.000 Before I start, I just want to say it's really cool to be here today. 00:32.000 --> 00:36.000 I came to Fostam the first time I think it was 2003. 00:36.000 --> 00:40.000 It was amazing. It was also absolutely overwhelming. 00:40.000 --> 00:42.000 I was afraid to talk to anybody. 00:42.000 --> 00:46.000 And all of these people seemed like, I don't know. 00:46.000 --> 00:53.000 It would be cool to be like them, but I just didn't think that that was something that I had in me. 00:53.000 --> 00:55.000 And yet here I'm today. 00:55.000 --> 01:00.000 And the road I took to get here was, I think, an unusual one. 01:00.000 --> 01:11.000 Because I'm here to talk about free suing, which is an open source software that I created and maintain. 01:11.000 --> 01:22.000 And yeah, suing. So for those of you who are in the room, because the room they actually wanted to get into had one of those dreaded the room is full signs. 01:22.000 --> 01:26.000 Okay, that this might be a shock, it's a bit of a niche topic. 01:26.000 --> 01:33.000 But don't panic. I'm going to do my best to make it interesting. 01:33.000 --> 01:38.000 Okay, so I got into suing by accident, really. 01:38.000 --> 01:41.000 It was the end of 2010. 01:41.000 --> 01:45.000 And I got sick with mono nucleosis. 01:45.000 --> 01:51.000 Also known as mono, also known as glantula fever, also known as the kissing disease. 01:51.000 --> 01:54.000 It's not a good evidence, but I was not in relationship at the time. 01:54.000 --> 01:58.000 So I can vouch that that label is accurate. 01:58.000 --> 02:03.000 The hallmark feature of mono is extreme fatigue. 02:03.000 --> 02:07.000 And I can tell you, I was so tired and exhausted, it was incredible. 02:07.000 --> 02:09.000 I was too tired, even to eat. 02:09.000 --> 02:11.000 I mean, I was so skinny. 02:11.000 --> 02:16.000 I mean, I don't recommend it, but it really mono gives a Zen pick around for its mono. 02:16.000 --> 02:18.000 It comes to weight loss. 02:18.000 --> 02:20.000 This was the end of 2010. 02:20.000 --> 02:24.000 And so by the end of my sick leave, because I couldn't work, 02:24.000 --> 02:26.000 it was coming up to the Christmas holidays. 02:26.000 --> 02:31.000 Between Christmas and New Year, I had time from time off from work, you know, from my job anyway. 02:31.000 --> 02:36.000 And so I found myself in these weird days between Christmas and New Year, 02:36.000 --> 02:39.000 feeling a little bit better, still not great. 02:39.000 --> 02:41.000 But like, so bored. 02:41.000 --> 02:44.000 I was like bored out of my mind, I'd been stuck in bad for a couple of weeks, 02:44.000 --> 02:46.000 and I was like, I need to do something. 02:46.000 --> 02:50.000 And I had a sewing machine that I had bought at one point, 02:50.000 --> 02:53.000 because I felt it was like, something you should have in your house 02:53.000 --> 02:55.000 to do repairs and stuff. 02:55.000 --> 02:57.000 But it had mostly been gathering dust. 02:57.000 --> 02:59.000 So I was like, you know what? 02:59.000 --> 03:01.000 I'm just going to make some clothes. 03:01.000 --> 03:02.000 I'm going to make something. 03:02.000 --> 03:05.000 So I ventured out to my local haver dashery. 03:05.000 --> 03:09.000 And I should point out that back then, I had no idea what a haver dashery was, 03:09.000 --> 03:13.000 because it's one of those weird words that I learned through sewing, 03:13.000 --> 03:17.000 but it's basically a shop where you can buy sewing supplies and, you know, 03:17.000 --> 03:20.000 knitting needles and things for textile crafts. 03:20.000 --> 03:21.000 Actually, went to this one. 03:21.000 --> 03:22.000 This is from Google Street Hill. 03:22.000 --> 03:26.000 It's the very dust in Runoff here in Brussels, 03:26.000 --> 03:30.000 very close to La Serujer, which is where I lived back then. 03:30.000 --> 03:34.000 So I went in there, I bought some fabric, you know, 03:34.000 --> 03:38.000 some trat and little bits and pieces that you need to get started, 03:38.000 --> 03:40.000 and I also bought a sewing pattern. 03:40.000 --> 03:44.000 Now, I don't really know that it was exactly this sewing pattern, 03:44.000 --> 03:46.000 but it might have well been. 03:46.000 --> 03:49.000 You know, this is sort of like the cover, the envelope, 03:49.000 --> 03:52.000 sewing pattern is actually inside of it. 03:52.000 --> 03:58.000 And so what I did in those final days of 2010 is I set behind the sewing machine, 03:58.000 --> 04:01.000 and I tried to follow the instructions and the pattern, 04:01.000 --> 04:04.000 and tried to make these trousers, because I was like, 04:04.000 --> 04:07.000 it would be nice to have some trousers to go to work, right? 04:07.000 --> 04:11.000 And then, lo and behold, in 2011, at the start of the year, 04:11.000 --> 04:14.000 when the holidays were over, I went to work, 04:14.000 --> 04:16.000 and I was wearing these new trousers, you know? 04:16.000 --> 04:19.000 And I wore them with sort of like confidence of like, 04:19.000 --> 04:21.000 yeah, I made this thing, ain't that great, 04:21.000 --> 04:25.000 and then also the ignorance of like not realizing how terrible they actually were, 04:25.000 --> 04:29.000 because, you know, my first pair of trousers was not great. 04:29.000 --> 04:34.000 These I made two years later, I don't have pictures of the first pair, I'm sorry. 04:34.000 --> 04:36.000 I think you can still see that they were handmade, 04:36.000 --> 04:40.000 but, you know, they're acceptable, and, you know, 04:40.000 --> 04:46.000 I think I can do better today, but, you know, these were sort of like, okay. 04:46.000 --> 04:49.000 So it was the start of the year, it was January, 04:49.000 --> 04:52.000 and I was really like hyped about this, you know, 04:52.000 --> 04:54.000 like not just that I had been sick, 04:54.000 --> 04:58.000 but then also to come out of it with something that I made with my own hands, 04:58.000 --> 05:01.000 that I could wear, you know, it was really like a great feeling, 05:01.000 --> 05:03.000 so I was like, okay, that's it now. 05:03.000 --> 05:06.000 From here on forward, I will make all of my own clothes. 05:06.000 --> 05:09.000 I will not buy anything, I will just make everything, 05:09.000 --> 05:11.000 I'm going to be that guy. 05:11.000 --> 05:16.000 Well, this is the issues with this to be honest. 05:16.000 --> 05:20.000 For starters, I quickly figured out that socks were not something I was going to make, 05:20.000 --> 05:24.000 because I don't need, and so, you know, I was like, okay, socks are okay. 05:24.000 --> 05:26.000 For the longest time, I only bought socks. 05:26.000 --> 05:29.000 Of course, I still wore the clothes that I already had, 05:29.000 --> 05:31.000 and then as those started wearing how to start realising, 05:31.000 --> 05:34.000 there's other things that are not that obvious for me to make. 05:34.000 --> 05:38.000 So that being said, until today, I still don't buy any clothes 05:38.000 --> 05:42.000 that I can make myself, and of course, 05:42.000 --> 05:47.000 I made everything I wearing today, because, you know, I felt this was important. 05:47.000 --> 05:50.000 Thank you. 05:50.000 --> 05:54.000 Not the hat though, should not the hat. 05:55.000 --> 05:59.000 Okay, so, like, I would refer to this as like the honeymoon period. 05:59.000 --> 06:02.000 I was really on the high of having that initial success, 06:02.000 --> 06:05.000 because, I mean, I was willing to fail. 06:05.000 --> 06:07.000 I just did it out of boredom, but it worked out, 06:07.000 --> 06:09.000 and I was like, this is great. 06:09.000 --> 06:12.000 And so, I immediately pictured myself as like, 06:12.000 --> 06:14.000 you know, this is going to be a life changing event, 06:14.000 --> 06:19.000 and I sort of imagined in my head that I'd be something like this guy, right? 06:19.000 --> 06:23.000 Just like this super swath, like, everything. 06:23.000 --> 06:25.000 And this has not happened, right? 06:25.000 --> 06:30.000 Because sewing does not really change who you are. 06:30.000 --> 06:32.000 I mean, I've learned a lot through it, 06:32.000 --> 06:34.000 and there's definitely things that have changed, 06:34.000 --> 06:36.000 but I'm still the same person, right? 06:36.000 --> 06:40.000 Some things that do change is that I'm a lot more conscious 06:40.000 --> 06:42.000 about the clothes that I'm wearing, 06:42.000 --> 06:45.000 and the clothes, how they fit, how they are made, stuff like that. 06:45.000 --> 06:48.000 There's a pay a lot more attention to what other people are wearing 06:48.000 --> 06:50.000 and so on and so forth. 06:51.000 --> 06:54.000 And if you're like, oh, but yeah, I also pay attention to 06:54.000 --> 06:56.000 what other people are wearing, you know? 06:56.000 --> 06:58.000 Because I saw such and such where it isn't that, 06:58.000 --> 07:00.000 I don't take talking, and I ran out to T-Moo 07:00.000 --> 07:03.000 to buy a knock-off version of that. 07:03.000 --> 07:05.000 That's not really what this is about. 07:05.000 --> 07:07.000 So, I think I need to explain this a little bit, 07:07.000 --> 07:09.000 with this strangle. 07:09.000 --> 07:12.000 So, at the top of this sort of 07:12.000 --> 07:15.000 triangular spectrum of people who might be drawn 07:15.000 --> 07:17.000 to sewing at the hobby, 07:17.000 --> 07:20.000 where the people who care about craft, right? 07:20.000 --> 07:23.000 And I put that at the top because that's where I reside. 07:23.000 --> 07:26.000 So, you know, I wanted to project this era of, you know, 07:26.000 --> 07:28.000 this is the best way, but that's not true. 07:28.000 --> 07:32.000 And then on the right hand side, if the people who care about style, 07:32.000 --> 07:34.000 right? So, the people at the top, they care about, like, 07:34.000 --> 07:37.000 how our things may take care about the fibers and, you know, 07:37.000 --> 07:40.000 like the threads and stuff like that and techniques, right? 07:40.000 --> 07:43.000 And then the people who are here predominantly interested in, 07:43.000 --> 07:46.000 like, does it look great, you know? 07:46.000 --> 07:49.000 And they might be interested in historical styles. 07:49.000 --> 07:51.000 And they know all of these rules about, like, oh, you should combine 07:51.000 --> 07:54.000 a double-breasted suit jacket with that length of winter code 07:54.000 --> 07:55.000 and stuff like that. 07:55.000 --> 07:57.000 Like, I got a lot of respect for those people, 07:57.000 --> 08:00.000 but like, for as I might, it's just not me, right? 08:00.000 --> 08:02.000 And then on the left side, 08:02.000 --> 08:05.000 or the people that maybe traditionally would think, 08:05.000 --> 08:07.000 or the most likely to get into sewing, 08:07.000 --> 08:12.000 people who read fashion magazines and, like, all into that stuff. 08:12.000 --> 08:15.000 But in my experience, those are not the people actually so, 08:15.000 --> 08:18.000 or actually end up enjoying it, because if you're chasing high, 08:18.000 --> 08:20.000 if you're going to have a less of a good time, 08:20.000 --> 08:23.000 then if you're interested in making something with your hands, 08:23.000 --> 08:25.000 or chasing, like, a particular style. 08:25.000 --> 08:27.000 And this does not have to look like that. 08:27.000 --> 08:29.000 These are also, like, you know, people who are, like, 08:29.000 --> 08:33.000 gods, or, you know, in other sort of niche things, 08:33.000 --> 08:36.000 are typically more drawn to sewing. 08:36.000 --> 08:38.000 All right. 08:38.000 --> 08:42.000 So, ain't be chover, that was it. 08:43.000 --> 08:46.000 So, as I mentioned, 08:46.000 --> 08:50.000 sewing is software to generate parametric sewing patterns, 08:50.000 --> 08:53.000 or I hope I mentioned that, and if not, then I did so now. 08:53.000 --> 08:57.000 So, it begs the question, what is the sewing pattern? 08:57.000 --> 08:59.000 You know, and I can show you one. 08:59.000 --> 09:01.000 This is a sewing pattern. 09:01.000 --> 09:04.000 It's a matter of fact, it's one generated by free sewing. 09:04.000 --> 09:07.000 It's our Simon pattern, which is our most popular one. 09:07.000 --> 09:09.000 It's a pattern for a button down shirt. 09:09.000 --> 09:12.000 But the sewing pattern really is just a blueprint 09:12.000 --> 09:14.000 to make a garment, right? 09:14.000 --> 09:17.000 So, all of the parts that you need to make a shirt, 09:17.000 --> 09:20.000 or lay it out, and then typically it comes with some instructions 09:20.000 --> 09:22.000 on how to put those together, 09:22.000 --> 09:26.000 but then experience people wouldn't even need those instructions. 09:26.000 --> 09:29.000 This is also a sewing pattern. 09:29.000 --> 09:32.000 This is a commercial sewing pattern. 09:32.000 --> 09:34.000 It's not from free sewing. 09:34.000 --> 09:37.000 It's one of those that comes with a sewing magazine, 09:37.000 --> 09:41.000 which is a popular way that people traditionally use together. 09:41.000 --> 09:43.000 Sewing patterns. 09:43.000 --> 09:47.000 Now, they try to save on paper here, so there's a lot going on, right? 09:47.000 --> 09:49.000 You can't really use this as this. 09:49.000 --> 09:51.000 People would typically trace that on paper, 09:51.000 --> 09:55.000 but basically the different colors are different parts of the pattern. 09:55.000 --> 09:57.000 You know, they sleeve the front, the back, and then so forth. 09:57.000 --> 10:02.000 But then also, every part is there in different sizes, right? 10:02.000 --> 10:06.000 Which is a problem that we also have with clothes in the store. 10:06.000 --> 10:10.000 I think that pretty much everybody here will know the frustration 10:10.000 --> 10:13.000 of going to the store trying to buy some clothes, 10:13.000 --> 10:15.000 and then, wait, these don't fit. 10:15.000 --> 10:16.000 What's going on? 10:16.000 --> 10:19.000 These legs are too short, or these arms are too long, 10:19.000 --> 10:22.000 and that's sort of stuff like, maybe after a while, 10:22.000 --> 10:25.000 you figure out how this brand kind of works for me. 10:25.000 --> 10:29.000 You know, or like you're unlucky, and basically nothing works for you. 10:29.000 --> 10:32.000 And we have the same problem with these store bought 10:32.000 --> 10:36.000 and commercial sewing patterns is that they're not made for you. 10:36.000 --> 10:39.000 They are just made for a set of standard sizes. 10:39.000 --> 10:43.000 But these, according to standard sizes, are just a lie. 10:43.000 --> 10:46.000 Because there is no such thing, this is just how the industry 10:46.000 --> 10:49.000 wants to commoditize the traditional craft of garment making, 10:49.000 --> 10:53.000 which was always made for a specific person, right? 10:53.000 --> 10:56.000 Now we have standard sizes, and so we have all of these problems, 10:56.000 --> 11:00.000 and sewing patterns that coming sizes have exactly the same problems. 11:02.000 --> 11:07.000 Historically, though, as I said, clothes were made for some money, 11:07.000 --> 11:11.000 made to measure, so to speak, or bespoke, as we sometimes call that, 11:11.000 --> 11:15.000 and there's actually two jobs that come into place. 11:15.000 --> 11:17.000 There's the tailor, and there's the cutter. 11:17.000 --> 11:21.000 And the reason that I bring this up is that, with the garment, 11:21.000 --> 11:25.000 if it's not in your own size, you can, you know, maybe roll up the sleeves or something, 11:25.000 --> 11:29.000 and with the sewing pattern, you can also make changes to the sewing pattern 11:29.000 --> 11:31.000 and make adaptations. 11:31.000 --> 11:34.000 But it's a little bit like patching a binary, you know? 11:34.000 --> 11:39.000 It's possible if you're knowledgeable about the subject that you know what you're doing, 11:39.000 --> 11:44.000 but it's going to be a lot easier if you have the source code of the sewing pattern, right? 11:44.000 --> 11:47.000 So what is the source code of the sewing pattern? 11:47.000 --> 11:51.000 Well, traditionally, the tailor is the person who actually makes the garment. 11:51.000 --> 11:54.000 These are the people who are experts with needle and thread sewing machine, 11:54.000 --> 11:56.000 and so on and so forth. 11:56.000 --> 11:59.000 And the cutter is the person who actually does the blueprint, 11:59.000 --> 12:03.000 comes up with the pattern, and then actually cuts it out of the fabric. 12:03.000 --> 12:09.000 Because historically, the cost of the fabric was like the biggest cost factor in manufacturing garments. 12:09.000 --> 12:14.000 So these people did not just sort of like come up with the blueprint and then advocate the responsibility, 12:14.000 --> 12:19.000 you know, they cut into the fabric, owning their decision of this is going to be it. 12:19.000 --> 12:24.000 And then once they had all of that ready, all of those pieces, they handed it over to the tailor. 12:24.000 --> 12:29.000 Incidentally, this is the origin of the phrase, having your cut out for you. 12:29.000 --> 12:35.000 Okay, so this is, like, as a species, we've been making garments for eons, right? 12:35.000 --> 12:37.000 And this is also a very old craft. 12:37.000 --> 12:41.000 This is an addition of the tailor and cutter. 12:41.000 --> 12:47.000 I picked this one because it's from the first of February, so to the date, this is from the 58 years old. 12:47.000 --> 12:51.000 You might think from the very fancy the tailor font, 12:52.000 --> 12:59.000 that is the thing, but actually the cutter is traditionally seen as the more high level sort of craft. 12:59.000 --> 13:03.000 It's like the most masterful craft is to actually cut out the garment, 13:03.000 --> 13:08.000 and then assembling it and making it is also very impressive, and there's also master tailors, 13:08.000 --> 13:14.000 but still cutter is sort of like up there, because it is like, you know, the most difficult skill. 13:14.000 --> 13:18.000 And so when we think about what is the source code of a sewing pattern, 13:18.000 --> 13:21.000 it really is what's going on inside the head of the cutter. 13:21.000 --> 13:26.000 You know, all of this experience, all of this know how, why do you put that line there? 13:26.000 --> 13:31.000 You know, what we're trying to do with the sewing pattern is still this sort of relevant experience 13:31.000 --> 13:36.000 and know how of a cutter into a blueprint so that you can just play the tailor role. 13:36.000 --> 13:37.000 Right? 13:37.000 --> 13:39.000 I just have to make the thing. 13:39.000 --> 13:43.000 So we, of course, would not know what is going on in those people's heads, 13:43.000 --> 13:46.000 if we were not that they wrote books about it, right? 13:46.000 --> 13:51.000 This is a 200 year old book, so once again, this is a very old craft that we're dealing with. 13:51.000 --> 13:54.000 This is about the art of cutting garments. 13:54.000 --> 13:56.000 You can find these books online. 13:56.000 --> 13:59.000 There are so old that they're in a public domain. 13:59.000 --> 14:02.000 This like this arcane language, right? 14:02.000 --> 14:07.000 Faded text and strong illustrations, like it's also quite mysterious, 14:07.000 --> 14:13.000 which you can also just buy a modern book, full color, which is probably a bit easier to decipher. 14:13.000 --> 14:16.000 And if you open one of these books, I have this one. 14:16.000 --> 14:19.000 You will find instructions like this one, you know? 14:19.000 --> 14:24.000 Draw a vertical line, mark the top at point A from point A square out to the right, 14:24.000 --> 14:29.000 measuring one quarter of the circumference of the chest, at two inches, mark this point at point B. 14:29.000 --> 14:32.000 Very typical drawing instructions. 14:32.000 --> 14:36.000 It's basically, okay, this is what the cutter would do, right? 14:36.000 --> 14:40.000 And so I bought that pattern and then tried to make a few other things, 14:40.000 --> 14:44.000 but I quickly got frustrated in those early months of 2011, 14:44.000 --> 14:46.000 you know, doing my new hobby. 14:46.000 --> 14:49.000 I got frustrated with this sizing issue, right? 14:49.000 --> 14:52.000 And so I learned more and more about sewing and I discovered, 14:52.000 --> 14:54.000 wait a minute, then I can just buy one of these books, 14:54.000 --> 14:57.000 and then I can plug in my own measurements. 14:57.000 --> 15:00.000 And then, in principle, should be perfect, right? 15:00.000 --> 15:03.000 So that's what I did to start it up with pen and paper, 15:03.000 --> 15:09.000 but I wanted these people who has trouble reading their own handwriting, you know? 15:09.000 --> 15:14.000 So this was quite frustrating, like I just didn't really, 15:14.000 --> 15:19.000 and at a certain moment I was like, it's got to be a better way to do this, right? 15:19.000 --> 15:22.000 What if I do this on a computer? 15:22.000 --> 15:26.000 And that really was the start of my journey that let me come here, 15:26.000 --> 15:30.000 because if that hadn't happened, I don't think I would be here today. 15:30.000 --> 15:33.000 So I'm going to quickly go over the timeline just to show, 15:33.000 --> 15:37.000 you know, how much time it took me to get here, because when I started out, 15:37.000 --> 15:40.000 I didn't really know what I was doing. 15:40.000 --> 15:44.000 So as I said, I started sewing at the end of 2010, 15:44.000 --> 15:47.000 first couple of months, I was using patterns, then I was like, 15:47.000 --> 15:52.000 I gotta do this on the computer, and once you're on the computer, 15:52.000 --> 15:55.000 you start making abstractions and stuff like that. 15:55.000 --> 16:00.000 And at a certain moment I was like, this is starting to become a little bit useful for me. 16:00.000 --> 16:02.000 I'm scratching my own it here. 16:02.000 --> 16:06.000 And as I mentioned, I came to France the morning 20 years ago. 16:06.000 --> 16:09.000 We didn't like these e-tars of free software and all that stuff. 16:09.000 --> 16:13.000 So I was like, I'm going to create a little website so that other people can benefit from this too. 16:13.000 --> 16:19.000 So in February 2012, I registered the domain, and then in September, I opened it up. 16:19.000 --> 16:23.000 It was not false back then, but that was just because I was completely embarrassed 16:23.000 --> 16:24.000 about the code that I wrote. 16:24.000 --> 16:26.000 I was like, I'm not sharing this. 16:26.000 --> 16:28.000 This is just terrible. 16:28.000 --> 16:30.000 Okay, fast forward a bit. 16:30.000 --> 16:35.000 This is the most old data that we have in free sewing production data base today. 16:35.000 --> 16:42.000 So the oldest accounts are from back there in January 2014, just for myself. 16:42.000 --> 16:48.000 And some test accounts, and then, you know, a bit later towards the start of 2015. 16:48.000 --> 16:50.000 It was like early access. 16:50.000 --> 16:52.000 We had some early adopters. 16:52.000 --> 16:58.000 And then towards the summer of 2017, I launched free sewing homework. 16:58.000 --> 17:01.000 So now it was open source. 17:01.000 --> 17:04.000 I had released this sort of core library earlier in March. 17:04.000 --> 17:07.000 But then I still had to build the UI and stuff like that. 17:07.000 --> 17:09.000 So that took some time. 17:09.000 --> 17:16.000 And to show that, you know, I was still really learning a lot about what it takes to develop software and stuff like that. 17:16.000 --> 17:19.000 I think this this graph will tell a great story. 17:19.000 --> 17:24.000 Because we have no data about all those users because there was a book and their registration date 17:24.000 --> 17:26.000 was not correctly saved in the database. 17:26.000 --> 17:29.000 And well, that's just how it is. 17:29.000 --> 17:31.000 We don't have that data now. 17:31.000 --> 17:35.000 But then when we released free sewing 3.0, I finally fixed that book. 17:35.000 --> 17:38.000 This also shows that I really don't keep track of these things. 17:38.000 --> 17:43.000 And so all those users are then registered on that date, right? 17:43.000 --> 17:48.000 So the scale of the graph now makes it seem like there's nothing going on there. 17:48.000 --> 17:53.000 But like, yeah, so at this point, we've registered about 50,000 people. 17:53.000 --> 17:56.000 But those are just all the people that had signed up there. 17:56.000 --> 18:00.000 And did I already got them way bigger than I ever imagined? 18:00.000 --> 18:03.000 Because I mean, it is a niche topic, you know? 18:03.000 --> 18:09.000 Like the previous two presentations ago was like at billions of people or your potential users like that. 18:09.000 --> 18:10.000 That's not true for sewing. 18:10.000 --> 18:16.000 Right? So 50,000 people signed up and then people were signing up at a clip of about, 18:16.000 --> 18:20.000 I don't know, like between between 3 and 7,000 users a month. 18:20.000 --> 18:26.000 At the end, this summer, last summer, we are at like 148,000 and something users. 18:26.000 --> 18:31.000 And yeah, I mean, I think that's a lot, I don't know. 18:31.000 --> 18:34.000 And then TikTok fans. 18:34.000 --> 18:39.000 And so yeah, we had some rough months. 18:39.000 --> 18:43.000 And now we're at 364,000, something users. 18:43.000 --> 18:49.000 And yeah, you know, it shows that I first speak with a book because it's just like one month and then back to normal. 18:49.000 --> 18:53.000 But like here you see it's more organic, you know, because we're shooting up and then we're shooting higher. 18:53.000 --> 18:56.000 And then it's sort of like tape was off. 18:56.000 --> 19:02.000 So yeah, look, those week numbers, you tell me, like everything is relative in life. 19:02.000 --> 19:08.000 But what I do know is that this is just not something that I imagined when I started out. 19:08.000 --> 19:13.000 But what I take more value in taking more stock in is this graph. 19:13.000 --> 19:19.000 Because in 2015 started accepting donations. 19:19.000 --> 19:24.000 And the reason I did that was that people were asking me, how can we donate? 19:24.000 --> 19:26.000 And I was like, you want to what? 19:26.000 --> 19:31.000 And then like, yeah, we like this and we want to support you. 19:31.000 --> 19:35.000 And I was like, okay, I didn't really think about that. 19:35.000 --> 19:37.000 And so I gave it some thought. 19:37.000 --> 19:40.000 And I was like, I don't really want to do this for a living. 19:40.000 --> 19:44.000 I already have a job and this risks becoming then the second job. 19:44.000 --> 19:45.000 And I don't want that. 19:45.000 --> 19:49.000 But after giving it some thought, I was like, you know what? 19:49.000 --> 19:53.000 We are pretty privileged to be able to do this for fun. 19:53.000 --> 19:56.000 Basically, a lot of people are not that privileged. 19:56.000 --> 19:58.000 A lot of people are in shitty situation. 19:58.000 --> 20:02.000 So yeah, give me your money and then I will just give it a charity. 20:02.000 --> 20:04.000 So that's what we've been doing ever since. 20:04.000 --> 20:09.000 And so until this point, we've given more than 70,000 euros to make sense of content 20:09.000 --> 20:12.000 or doctors with that borders. 20:12.000 --> 20:14.000 And this is really for me, the thing. 20:20.000 --> 20:21.000 I mean, thank you. 20:21.000 --> 20:25.000 But it's so that people's money, you know, that, right? 20:25.000 --> 20:29.000 But now, at jokes aside, I'm really happy about this because, you know, 20:29.000 --> 20:32.000 this is all fun and writing software and I learned a lot of stuff like that. 20:32.000 --> 20:37.000 But we also have to be, you know, aware of the fact that it's a privileged position to be. 20:37.000 --> 20:40.000 And a lot of people are in dire straits and this is nice. 20:40.000 --> 20:41.000 This is a nice thing to do. 20:41.000 --> 20:42.000 All right. 20:42.000 --> 20:47.000 So I'm having a hard time when I talk to people who come from a sewing perspective 20:47.000 --> 20:50.000 to explain, free sewing because of all the open source stuff. 20:50.000 --> 20:52.000 And I think vice versa. 20:52.000 --> 20:55.000 Here there might be people who are like, I can't even imagine what this is. 20:55.000 --> 20:58.000 So I'm going to do like a 30 second live demo. 20:58.000 --> 21:00.000 Let's hope I don't mess this up. 21:00.000 --> 21:03.000 Just do sort of show what it is that we offer. 21:03.000 --> 21:09.000 Why does 300 and so many people wait, now this doesn't show up. 21:09.000 --> 21:14.000 Trying to drag it to the other screen. 21:14.000 --> 21:16.000 But there we go. 21:16.000 --> 21:19.000 Not great at this. 21:19.000 --> 21:22.000 Okay, so, um, well, so this is the sewing pattern. 21:22.000 --> 21:25.000 This is a simple one because it's about the principle. 21:25.000 --> 21:29.000 And then on the bunch on the right here, so this already has my measurements loaded. 21:29.000 --> 21:31.000 And it's parametric. 21:31.000 --> 21:33.000 So if you load this different measurements, 21:33.000 --> 21:36.000 I'm not going to go into all of that because I just have to show you like, you know, 21:36.000 --> 21:40.000 if we do this and then we say like, okay, I want that a little bit more like this. 21:40.000 --> 21:45.000 More like that, you know, then you can just change that and this more like that. 21:45.000 --> 21:52.000 So that's basically the what we do and what we offer and what drives the people to free sewing, 21:52.000 --> 21:54.000 which is one of us. 21:54.000 --> 21:58.000 As I said, it's going to be a short demo. 21:59.000 --> 22:05.000 Well, I mean there's more but like, you know, this time limits and I'm trying to be respectful of them. 22:05.000 --> 22:08.000 So what is parametric design? 22:08.000 --> 22:10.000 Because that's basically what we're doing. 22:10.000 --> 22:16.000 And I think that really goes back to that moment where I switched from paper to computer. 22:16.000 --> 22:22.000 Because if you look at these instructions and they're talking about one quarter of the circumference of the chest. 22:22.000 --> 22:27.000 When you're on paper, you're going to measure one quarter of whatever it is and you're going to draw that line. 22:27.000 --> 22:33.000 But when you make the step to computer, I think a lot of people in this room will just sort of intuitively say, 22:33.000 --> 22:36.000 well, we're going to put that in a variable, right? 22:36.000 --> 22:38.000 The chest and I will just take one quarter of that. 22:38.000 --> 22:40.000 Like that seems kind of obvious. 22:40.000 --> 22:43.000 Well, that's parametric design really. 22:43.000 --> 22:46.000 Because now you can just change that variable and your design will adapt. 22:46.000 --> 22:53.000 So traditional sewing pattern if we sort of make the code translation would be something statically defined. 22:53.000 --> 22:58.000 We have a pattern and then it's some sort of digital representation of what a sewing pattern is. 22:58.000 --> 23:04.000 With parametric design, or pattern can take some inputs and then adapt itself. 23:04.000 --> 23:14.000 And then return a digital representation of a sewing pattern that takes that inputs into account, you know, a function basically. 23:15.000 --> 23:20.000 So that is sort of like the high level ID behind parametric design. 23:20.000 --> 23:22.000 So how do we implement that in free sewing? 23:22.000 --> 23:27.000 What do parametric sewing patterns look like? Well, they look like this. 23:27.000 --> 23:30.000 But, you know, this is not a masterclass. 23:30.000 --> 23:33.000 So today we're going to focus on this part, right? 23:33.000 --> 23:38.000 So on the left you have your input, then you have your pattern, which is one function. 23:38.000 --> 23:41.000 But then under the hood, we actually have different parts. 23:41.000 --> 23:46.000 Different parts are like the front, the back, the sleeve, the cuff, the collar, that sort of stuff. 23:46.000 --> 23:48.000 They sort of like exist on their own. 23:48.000 --> 23:53.000 And all of those are going to be a function. They're going to have points, they're going to have parts which are lines. 23:53.000 --> 23:55.000 We're going to get into that in a second. 23:55.000 --> 23:59.000 And then we can render that to SVG or we can also render to react. 23:59.000 --> 24:00.000 Right? 24:00.000 --> 24:04.000 Today, to get to a simple pattern, well, a simple. 24:04.000 --> 24:08.000 You get to a parametric sewing pattern. This is all we need, right? 24:08.000 --> 24:12.000 And if you're thinking, then what's all that other stuff? Why do you have to make it so complicated? 24:12.000 --> 24:16.000 Well, all that other stuff is for more advanced use cases, right? 24:16.000 --> 24:21.000 So vertically you have stacks and stacks allow you, normally if you have different parts, 24:21.000 --> 24:25.000 they are laid out next to each other, stacks allow you to stack them on top of each other. 24:25.000 --> 24:27.000 So you can see a left. 24:27.000 --> 24:29.000 And then vertically these boxes are different sets. 24:29.000 --> 24:33.000 So rather than give our pattern one set of like measurements and all that, 24:33.000 --> 24:35.000 you're going to give it multiples. 24:35.000 --> 24:39.000 And we use that to do things like show the effect of a particular option, 24:39.000 --> 24:41.000 a particular parameter, on the design. 24:41.000 --> 24:47.000 So you can see here, the designer can set a minimum and a maximum value of that option that makes sense. 24:47.000 --> 24:50.000 And we can visualize that by using this extra feature. 24:50.000 --> 24:56.000 Another thing that we do there is we run automated testing or repository to test patterns for the quality assurance. 24:56.000 --> 24:59.000 Make sure that they don't go off the rails. 24:59.000 --> 25:01.000 We test this for a range of sizes. 25:01.000 --> 25:06.000 Measurements that we have, but we also test this for both loads and like giants, right? 25:06.000 --> 25:12.000 Because a good parametric design should adapt to the extremes of that sort of size range. 25:12.000 --> 25:17.000 If that looks familiar to you because you're used to sewing, it looks a bit like a commercial sewing pattern, 25:17.000 --> 25:22.000 but there's an important difference here that I have to explain, which is drafting versus grading. 25:22.000 --> 25:27.000 So drafting a draft of a sewing pattern, we call it drafting when you make it a sewing pattern. 25:27.000 --> 25:31.000 grading is how things are done traditionally in commercial sewing patterns. 25:31.000 --> 25:35.000 So have an example here, this is a commercial sewing pattern. 25:35.000 --> 25:37.000 And this basically comes in sizes. 25:37.000 --> 25:41.000 But only one of these sizes is typically drafted from scratch. 25:41.000 --> 25:45.000 You know, with like quarter of measurement, quarter of test stuff like that that I explained earlier. 25:45.000 --> 25:49.000 The rest of those sizes are sort of like extrapolated. 25:49.000 --> 25:52.000 Add a little bit there, add a little bit there, and a little bit there. 25:52.000 --> 25:53.000 Okay, that's the next size. 25:53.000 --> 25:55.000 And then once again, and then maybe also down. 25:55.000 --> 25:58.000 That's how it's made, this is called grading, right? 25:58.000 --> 26:00.000 On the left, we have a free sewing pattern. 26:00.000 --> 26:03.000 You put in the measurements and it comes out for you, right? 26:03.000 --> 26:04.000 So no grading. 26:04.000 --> 26:06.000 Now, why does this matter? 26:06.000 --> 26:13.000 Well, because parametric design is better in every way, except in the ways that it is not, right? 26:13.000 --> 26:20.000 By which I mean, on the right side with a graded pattern, you might not get good fit, 26:20.000 --> 26:28.000 but you will also always have something that resembles a normal sized garment, maybe not your size. 26:28.000 --> 26:35.000 On the left side with parametric design, you're really vulnerable to the garbage in garbageized problem, right? 26:35.000 --> 26:38.000 If people put in like bonkers measurements, like that one, 26:38.000 --> 26:42.000 Well, the result is going to be like real bad, like unwareable and makeable. 26:42.000 --> 26:47.000 And that's a problem that we have, because when you think about this at one point, 26:47.000 --> 26:52.000 do you tell the user, hey, these measurements that can't be right? 26:52.000 --> 26:55.000 Because maybe this right, you don't know their body. 26:55.000 --> 27:02.000 And, you know, it's really sort of like, potentially hurtful to tell people that I think you should double check your measurements 27:02.000 --> 27:04.000 because something seems off, right? 27:04.000 --> 27:08.000 We shouldn't be making assumptions about people's bodies. 27:08.000 --> 27:11.000 Like this is a bit of a mind field. 27:11.000 --> 27:14.000 So we tend to not say too much, and you know, 27:14.000 --> 27:17.000 sometimes that the instrument results, because the input is bad. 27:17.000 --> 27:22.000 I think it's fair to put that out there as like that's a problem. 27:22.000 --> 27:25.000 Okay, let's look at how this actually works. 27:25.000 --> 27:27.000 We're going to look at some code now, right? 27:27.000 --> 27:31.000 So on the left we have our instructions that we're going to use as a guide, 27:31.000 --> 27:34.000 and then on the right we're going to see how do we turn that into code, right? 27:34.000 --> 27:39.000 So we have our function, but we already learned actually it's not like that. 27:39.000 --> 27:43.000 We have a function, wait, what I'm saying here. 27:43.000 --> 27:48.000 So we have a function that gets apparently this, and we're going to return our pattern, 27:48.000 --> 27:50.000 or a digital representation. 27:50.000 --> 27:55.000 But as I was saying, we know that every part from sleeve back all that stuff, 27:55.000 --> 27:57.000 is going to be something. 27:57.000 --> 28:01.000 So we have an example here, our front part, is a function, 28:01.000 --> 28:06.000 I switch to fat iron notation here, and it gets a bunch of parameters, right? 28:06.000 --> 28:10.000 And the free sewing core library is going to give you a lot of parameters that you can work with. 28:10.000 --> 28:13.000 One of them is the part object, right? 28:13.000 --> 28:15.000 Which is actually the thing that we're doing. 28:15.000 --> 28:18.000 So what we're going to do is we're going to mutate this object, 28:18.000 --> 28:21.000 and then we're going to return it, right? 28:21.000 --> 28:24.000 So if we look at our instructions on the left, 28:24.000 --> 28:29.000 we need to draw a vertical line and mark the top of a point A, okay? 28:29.000 --> 28:30.000 We need to create a point. 28:30.000 --> 28:31.000 How do we do that? 28:31.000 --> 28:36.000 Well, we can destructure points, which is an object that holds all the points of the part, 28:36.000 --> 28:39.000 and we can destructure the point constructor. 28:39.000 --> 28:43.000 And now we just do points.A, it's new point zero zero. 28:43.000 --> 28:45.000 Because the point takes the x and the y-coordinates, 28:45.000 --> 28:48.000 because we're just mapping a point in a 2D plane. 28:48.000 --> 28:50.000 This is not rocket science, right? 28:50.000 --> 28:51.000 It's got a straightforward. 28:54.000 --> 28:57.000 Now we need to do from point A square out to the right, 28:57.000 --> 28:59.000 measuring one quarter circumference, it's just okay. 28:59.000 --> 29:01.000 So circumference are the chest. 29:01.000 --> 29:02.000 How do we get that in free sewing? 29:02.000 --> 29:04.000 Well, you get an object that is called measurements, 29:04.000 --> 29:06.000 that you can also destructure, 29:06.000 --> 29:09.000 and it holds all the measurements that the user supplied, 29:09.000 --> 29:10.000 in millimeters. 29:10.000 --> 29:11.000 Okay, cool. 29:11.000 --> 29:14.000 So we can do measurement chest over four. 29:14.000 --> 29:15.000 All right. 29:15.000 --> 29:16.000 So far, so good. 29:16.000 --> 29:17.000 We got this. 29:17.000 --> 29:20.000 Now we need to add two inches. 29:20.000 --> 29:21.000 Okay. 29:21.000 --> 29:25.000 A bit of a problem when we think about the fact that we need to support ball 29:25.000 --> 29:27.000 floats and grown-ups. 29:27.000 --> 29:31.000 How do we translate these two inches into something that makes sense? 29:31.000 --> 29:33.000 And what even are these two inches? 29:33.000 --> 29:36.000 Well, it says there that this is ease, but like what is ease? 29:36.000 --> 29:37.000 Right? 29:37.000 --> 29:40.000 I think we probably need to do a little side adventure here and explain what 29:40.000 --> 29:42.000 is, don't worry, just one slide. 29:42.000 --> 29:47.000 So ease is what is extra fabric in the garments that allows you to move. 29:47.000 --> 29:50.000 So that later on the left would not be able to move our arm 29:50.000 --> 29:52.000 if there was no ease in the garment. 29:52.000 --> 29:54.000 You would get stock, right? 29:54.000 --> 29:56.000 So this is sort of like functional ease. 29:56.000 --> 29:59.000 It's added to the garments so that you can move, right? 29:59.000 --> 30:01.000 Then we also have design ease. 30:01.000 --> 30:05.000 In the middle, the t-shirt that that lady's wearing is way too big. 30:05.000 --> 30:07.000 I mean, if you don't see that, that's fine. 30:07.000 --> 30:08.000 But trust me, it's way too big. 30:08.000 --> 30:12.000 You see the shoulder seam is halfway around down her arm. 30:12.000 --> 30:14.000 But that's just the style choice. 30:14.000 --> 30:16.000 So when we say it's too big, it's not too big. 30:16.000 --> 30:19.000 It's absolutely fine, but like, you know, 30:19.000 --> 30:23.000 if you look at the sewing patterns like the wrong sides for her, 30:23.000 --> 30:24.000 but it's the style choice. 30:24.000 --> 30:26.000 So that's design ease. 30:26.000 --> 30:28.000 And then finally, we also have a negative ease. 30:28.000 --> 30:31.000 Negative ease is when the garment is actually too small, 30:31.000 --> 30:36.000 but you can also, you know, you need stretch to use negative ease. 30:36.000 --> 30:39.000 And this is typically used so that the garment is like tight. 30:39.000 --> 30:44.000 Sportswear, swimwear, skinny jeans, they'll have negative ease. 30:44.000 --> 30:45.000 All right. 30:45.000 --> 30:46.000 Back to it. 30:46.000 --> 30:48.000 So we know, okay, so this is ease. 30:48.000 --> 30:49.000 So how do we do that? 30:49.000 --> 30:53.000 So if we sewing, we're going to define a so-called design option here. 30:53.000 --> 30:57.000 Because if we're adding all this stuff, why not let the user control this? 30:58.000 --> 31:01.000 Why should we decide how much ease there is, right? 31:01.000 --> 31:04.000 So typically, we're going to destruct your options object, 31:04.000 --> 31:05.000 and then there's going to be an option, 31:05.000 --> 31:07.000 and we're going to call it chest ease now, 31:07.000 --> 31:09.000 and then we do one plus because it's a percentage, 31:09.000 --> 31:12.000 and divide by four and both your own goal. 31:12.000 --> 31:13.000 Okay. 31:13.000 --> 31:14.000 Adding points. 31:14.000 --> 31:15.000 We've got that. 31:15.000 --> 31:18.000 But we need to connect the dots at some point. 31:18.000 --> 31:22.000 So those we call paths in free sewing. 31:22.000 --> 31:24.000 And I'll give you an example. 31:24.000 --> 31:28.000 So once again, just like we did with points and points, 31:28.000 --> 31:31.000 the constructor, we have paths which also hold the paths, 31:31.000 --> 31:33.000 and the path constructor. 31:33.000 --> 31:35.000 Parts of example is new paths. 31:35.000 --> 31:38.000 Instantiate paths, low parameters. 31:38.000 --> 31:41.000 And then we have all of these methods, move, fly and curve. 31:41.000 --> 31:42.000 Right? 31:42.000 --> 31:45.000 And if you've ever worked with both scripts, SVG, 31:45.000 --> 31:49.000 Canvas, or basically most graphics APIs, 31:49.000 --> 31:52.000 they'll use this sort of way of drawing. 31:52.000 --> 31:53.000 Right? 31:53.000 --> 31:55.000 It's sort of this pen-polar way of doing. 31:55.000 --> 31:59.000 So move, move somewhere without drawing a line, line draws a line, 31:59.000 --> 32:02.000 and then curve uses cubic bestier curves. 32:02.000 --> 32:05.000 And once again, I don't match the time to explain what that is, 32:05.000 --> 32:07.000 but I assume a lot of you know, 32:07.000 --> 32:10.000 and if not, it's quite intuitive, check Wikipedia. 32:10.000 --> 32:13.000 Okay. 32:13.000 --> 32:17.000 So adding points and lines that's, you know, 32:17.000 --> 32:20.000 what's the value of resowing. 32:20.000 --> 32:24.000 We also have a lot of sort of helper methods in our API 32:24.000 --> 32:28.000 to make it easy to do things that you typically do in a sewing pattern. 32:28.000 --> 32:29.000 Right? 32:29.000 --> 32:32.000 You can 100% use this to do other 2D line drawing stuff, 32:32.000 --> 32:34.000 but like it's really for sewing patterns. 32:34.000 --> 32:37.000 You know, an example here is shift traction towards, 32:37.000 --> 32:39.000 you can call it on a point to say like, 32:39.000 --> 32:41.000 okay, I need the point between these two points. 32:41.000 --> 32:43.000 You know, that's sort of stuff. 32:43.000 --> 32:46.000 The paths also has a bunch of methods. 32:46.000 --> 32:49.000 Let me put them on the slide here quickly. 32:49.000 --> 32:51.000 Don't worry, I'm not going to go into them, 32:51.000 --> 32:54.000 but resowing the death slash reference slash API, 32:54.000 --> 32:56.000 has all of the free sewing API documentation, 32:56.000 --> 32:58.000 with examples and code and stuff like that. 32:58.000 --> 33:03.000 So, you know, you can look into it if you're interested. 33:03.000 --> 33:06.000 Okay, I'm going to give you a complete example now 33:06.000 --> 33:11.000 of how you can create a new design as we call that, right? 33:11.000 --> 33:15.000 The first thing you do is you import the design, 33:15.000 --> 33:19.000 what we call super constructor from a free sewing core library. 33:19.000 --> 33:21.000 Then we have some internationalization data, 33:21.000 --> 33:23.000 we have some metadata about, 33:23.000 --> 33:26.000 and then we have our actual parts that we constructed earlier. 33:26.000 --> 33:27.000 Right? 33:27.000 --> 33:30.000 And then to create a design, I've called it for them. 33:30.000 --> 33:34.000 You do a new design because design is a super constructor, 33:34.000 --> 33:36.000 so it will return a constructor, 33:36.000 --> 33:40.000 and then you give it some metadata and basically the list of parts. 33:40.000 --> 33:41.000 Right? 33:41.000 --> 33:43.000 So, we now have for them, which is a constructor, 33:43.000 --> 33:45.000 and if you instantiate it, you get a pattern. 33:45.000 --> 33:49.000 So, we have design and an instance of a design as a pattern. 33:49.000 --> 33:51.000 And then we export that stuff, 33:51.000 --> 33:55.000 and we use name and export so people can import a metadata 33:55.000 --> 33:57.000 without having to instantiate a pattern. 33:57.000 --> 34:01.000 So, let's look at all those different imports that we have there. 34:01.000 --> 34:04.000 This is the internationalization data, 34:04.000 --> 34:05.000 aka translation. 34:05.000 --> 34:08.000 So, our core library supports translation, 34:08.000 --> 34:11.000 and at a certain moment, we offered free sewing 34:11.000 --> 34:14.000 like the website in six different languages, 34:14.000 --> 34:19.000 but we had to stop that because the maintenance was just killing us. 34:19.000 --> 34:21.000 So, now we're just English. Sorry about that. 34:21.000 --> 34:23.000 But we still support translation, 34:23.000 --> 34:25.000 we just only provide English. 34:25.000 --> 34:29.000 And these days, with AI, I think most people can get around that. 34:29.000 --> 34:32.000 So, this is just a little bit of a structure, 34:32.000 --> 34:34.000 with the title and the design and the part names, 34:34.000 --> 34:36.000 and the strings that we might be using, 34:36.000 --> 34:37.000 and then the options. 34:37.000 --> 34:40.000 And you see that I used hello for them there. 34:40.000 --> 34:43.000 We have this thing where if you're going to put text in the pattern, 34:43.000 --> 34:46.000 you need to make sure that you're using actually a translation key, 34:46.000 --> 34:50.000 rather than the real text that way you can get translated. 34:50.000 --> 34:52.000 Now, we have some metadata. 34:52.000 --> 34:55.000 This is where we blur the line between what the core library does, 34:55.000 --> 34:58.000 and then what we do in our monorepo, 34:58.000 --> 35:00.000 the title of these patterns together, 35:00.000 --> 35:02.000 and give some information in the front end. 35:02.000 --> 35:04.000 The core library doesn't care at all about this. 35:04.000 --> 35:07.000 This is just to help front end integration stuff like that. 35:08.000 --> 35:10.000 And then here, we're finally at the good stuff. 35:10.000 --> 35:13.000 This is our part, you know? 35:13.000 --> 35:16.000 The only difference is that we're previously, 35:16.000 --> 35:19.000 we said it's a function. 35:19.000 --> 35:23.000 Now, our function is on the draft property, 35:23.000 --> 35:25.000 and we have some extra data, a name. 35:25.000 --> 35:28.000 We tell it which measurements are required, 35:28.000 --> 35:30.000 and our options are stuff like that. 35:30.000 --> 35:32.000 And the reason that this is important is that every part 35:32.000 --> 35:34.000 and free sewing stands on its own. 35:34.000 --> 35:36.000 So you can freely combine parts from different designs 35:36.000 --> 35:38.000 to make your own Frankenstein design. 35:38.000 --> 35:40.000 That's 100% supportive. 35:40.000 --> 35:41.000 Okay. 35:41.000 --> 35:44.000 I'm going to just briefly mention, 35:44.000 --> 35:46.000 so now we have a new design, 35:46.000 --> 35:48.000 and it can go in our collection. 35:48.000 --> 35:51.000 I'm going to briefly skip through 35:51.000 --> 35:53.000 how you get from that design to a pattern. 35:53.000 --> 35:54.000 Should you be interested? 35:54.000 --> 35:56.000 So you can just import your pattern there. 35:56.000 --> 35:59.000 We also import a plugin to style the SVG. 35:59.000 --> 36:01.000 Any of you a pattern is a new. 36:01.000 --> 36:02.000 Fulls the design. 36:02.000 --> 36:04.000 You give it all of the options that you want. 36:04.000 --> 36:06.000 You use the plugin, and you call draft. 36:06.000 --> 36:08.000 And then we call render on that. 36:08.000 --> 36:09.000 We get the SVG. 36:09.000 --> 36:11.000 That's all there is to it. 36:11.000 --> 36:13.000 If you want to get started with free sewing, 36:13.000 --> 36:16.000 you can start on your own with 36:16.000 --> 36:17.000 mpxet free sewing class studio, 36:17.000 --> 36:20.000 which pins up our development environments, 36:20.000 --> 36:23.000 or you can check out either our monorepo on code work 36:23.000 --> 36:25.000 or a fork of it, 36:25.000 --> 36:27.000 and then you can run mpm kickstart. 36:27.000 --> 36:30.000 For the people who have a sewing background, 36:30.000 --> 36:33.000 we often team up with people who have more of a coding background, 36:33.000 --> 36:36.000 and people with more of a sewing background to make one design. 36:36.000 --> 36:38.000 So in the venn diagram, 36:38.000 --> 36:40.000 there's not that many people in the middle. 36:40.000 --> 36:42.000 So teaming up is a good way to go. 36:42.000 --> 36:46.000 So if you're watching the stream or here and more from the sewing background, 36:46.000 --> 36:48.000 you can totally reach out to us. 36:48.000 --> 36:51.000 We'll hook you up with somebody's good at code. 36:51.000 --> 36:53.000 So you can run free sewing in Node.js 36:53.000 --> 36:56.000 or another JavaScript runtime like Bond or Denno. 36:56.000 --> 36:59.000 On the back end, on a serverless function, 36:59.000 --> 37:03.000 or of course in the browser like we do on free sewing.eu. 37:05.000 --> 37:08.000 I'm going to looking at the clock. 37:08.000 --> 37:13.000 So there's a stuff that we do for a previous speaker talk about this, 37:13.000 --> 37:17.000 there's this difference between your target audience being developers, 37:17.000 --> 37:19.000 or your target audience being users. 37:19.000 --> 37:20.000 So on the left side, you know, 37:20.000 --> 37:22.000 we publish and again packages, 37:22.000 --> 37:25.000 semantic versioning, we keep a change low API docs, 37:25.000 --> 37:27.000 developer experience, all of that stuff. 37:27.000 --> 37:30.000 But then on the right, it's like we have to create an entire UI. 37:30.000 --> 37:32.000 We have to support export to PDF. 37:32.000 --> 37:36.000 We have to let people tile in page sizes for their printer. 37:36.000 --> 37:38.000 You know, we need to provide sewing instructions, 37:38.000 --> 37:41.000 website docs, they need to be able to manage their account, 37:41.000 --> 37:42.000 like a whole bunch of stuff. 37:42.000 --> 37:45.000 And of course, the scope of the project gets quite a bit wider 37:45.000 --> 37:49.000 when you actually start building stuff for end users. 37:49.000 --> 37:54.000 So, you know, this is sort of like a big thing. 37:54.000 --> 37:58.000 I want to quickly talk about the infrastructure we have, 37:58.000 --> 38:00.000 in case there's people who are more from that background. 38:00.000 --> 38:04.000 So we are hosted on statichost.eu today, 38:04.000 --> 38:06.000 which uses the Bonnie CDN. 38:06.000 --> 38:09.000 The free sewing website is a completely static pile of HTML, 38:09.000 --> 38:11.000 CSS and JavaScript. 38:11.000 --> 38:14.000 So we basically ship all the code to the user and let them run it. 38:14.000 --> 38:16.000 Sort of like a bring your own compute. 38:16.000 --> 38:18.000 Thing, which means that it's, 38:18.000 --> 38:20.000 we don't have to pay for that and that's good. 38:20.000 --> 38:23.000 The flip side of that is that we have to ship all of that code. 38:23.000 --> 38:28.000 So I think we passed eight terabytes of bandwidth per month last year. 38:28.000 --> 38:30.000 So, you know, it's a lot. 38:30.000 --> 38:34.000 But thankfully statichost has made a good deal for us. 38:34.000 --> 38:37.000 And then we have a backend, which is the rest API express. 38:37.000 --> 38:40.000 We use SQLite because we like it simple. 38:40.000 --> 38:44.000 And then we also host our own forum instance. 38:44.000 --> 38:45.000 Okay. 38:45.000 --> 38:50.000 So, lessons that I've learned as a maintainer. 38:50.000 --> 38:51.000 This has been a long journey. 38:51.000 --> 38:53.000 I learned a lot along the way. 38:53.000 --> 38:54.000 It wasn't always easy. 38:54.000 --> 38:59.000 So here are three tips for people who might end up in a similar situation. 38:59.000 --> 39:02.000 The first is to touch grass, as they say. 39:02.000 --> 39:05.000 This is me and my wife and a cycling trip. 39:05.000 --> 39:06.000 I like to cycle. 39:06.000 --> 39:09.000 And it's good to go out there and do something different. 39:09.000 --> 39:11.000 My day job is computers. 39:11.000 --> 39:13.000 Free sewing is also computers. 39:13.000 --> 39:16.000 And like, do sometimes just need to do something else. 39:16.000 --> 39:19.000 So, you know, while on one hand I want to encourage you 39:19.000 --> 39:20.000 to get into this stuff. 39:20.000 --> 39:24.000 On the other hand, I'm also like, you know, step away from time to time. 39:24.000 --> 39:27.000 The second thing is that people come and go. 39:27.000 --> 39:30.000 This is my cat who passed away sadly last year. 39:30.000 --> 39:32.000 And I was really heartbroken by it. 39:32.000 --> 39:35.000 But then it's better to have had her than to have not had her. 39:35.000 --> 39:42.000 And I think it's the same with, you know, contributors or people who support the project financially. 39:42.000 --> 39:44.000 Like, they go. 39:44.000 --> 39:47.000 And, you know, they might have other interest in the lives of like that. 39:47.000 --> 39:48.000 And like, it always hurts. 39:48.000 --> 39:49.000 It always does. 39:49.000 --> 39:56.000 But then you have to be, you know, mindful of the fact that, you know, there's all those people out there who didn't contribute. 39:56.000 --> 39:58.000 Then you really need to be appreciative. 39:58.000 --> 40:01.000 And I am very appreciative of all the contributors of free sewing. 40:01.000 --> 40:03.000 All the people who support it. 40:03.000 --> 40:05.000 I think that's really good. 40:05.000 --> 40:10.000 And then the final piece of advice is that you should prepare for retirement. 40:10.000 --> 40:14.000 What I mean by that is that at the beginning you're going to be working on your own. 40:14.000 --> 40:15.000 Right? 40:15.000 --> 40:18.000 In a certain moment, we're going to have other people helping out. 40:18.000 --> 40:19.000 And that is fantastic. 40:19.000 --> 40:26.000 But I think that you should always try to think about, okay, but like, what can I give away so that other people can take care of it? 40:26.000 --> 40:27.000 Right? 40:27.000 --> 40:32.000 Because I think that the ultimate goal should be that the project algorithms you and it's bigger than what you can do. 40:32.000 --> 40:41.000 I think it's also a good ego check to be considered the fact like it would be good if I can give this to other people so that they can carry it even further than I have been carrying it. 40:42.000 --> 40:45.000 All right, that's a bit of old man advice. 40:45.000 --> 40:54.000 And then the final thing that I want to get into is the sort of interdisciplinary false difficult work. 40:54.000 --> 40:58.000 You know, I learned a lot through this journey when I started out. 40:58.000 --> 41:00.000 I didn't really know what I was doing. 41:00.000 --> 41:02.000 I was so far out of my comfort zone. 41:02.000 --> 41:10.000 But like when I look back now, I'm very happy of all the lessons that I learned and I feel much more confident in the code I write and the stuff that I do. 41:10.000 --> 41:28.000 And it's been really great, but at the same time, the more I know, the more I am conscious of my own limitations and the fact that, well, you know, yeah, I guess I'm a developer and how, but like I, I'm sure that this kind of people in this room who will, you know, or much better at this stuff than I am. 41:28.000 --> 41:34.000 And then on the flip side of that in the sewing thing is like, yeah, I'm pretty good at making clothes, you know, I can do that. 41:34.000 --> 41:38.000 But like, I also know a lot of the people are much better at that than I am. 41:38.000 --> 41:47.000 Yet somehow in combining these two things, sort of ended up with something that is seems to be valuable to a lot of people. 41:47.000 --> 41:55.000 So if you're like me, first time at Phos Demore, if you're just like a little bit like I just don't think that I have what it takes to write a new font and framework or whatever. 41:55.000 --> 42:07.000 Like you don't have to. You can look around to the other interesting life and try to find out other ways there that I can sort of combine these things combine different skills and then come up with something that is, I don't know, maybe great. 42:08.000 --> 42:11.000 Do you have any questions? 42:25.000 --> 42:27.000 Amazing talk. 42:28.000 --> 42:32.000 I'm using Simlee. I'm wondering I'm using Simlee. 42:32.000 --> 42:46.000 Oh, okay. I'm wondering if you have a way to import to translate patterns that I created in Simlee to free sewing and then kind of moving on. 42:46.000 --> 42:48.000 Yeah, Simlee is nice. 42:49.000 --> 42:52.000 Yeah, so for people who don't know, just with a complex. 42:52.000 --> 43:03.000 Simlee is a seemingly valentina, the forks of the same codebase is also a software to create sewing patterns, but it's like a point and click graphical thing, right? 43:03.000 --> 43:06.000 Where is free sewing is patterns of codes? 43:06.000 --> 43:10.000 So to answer your questions, can those patterns be translated in principle? 43:10.000 --> 43:16.000 Yes, because they're defined in XML, but then the question is, what's the parametric angle? 43:16.000 --> 43:22.000 Because Simlee does not really enforce that the way that we do, so you can get a pattern, but will that pattern and work? 43:22.000 --> 43:28.000 And when we put something on our website, we have a certain bar of like, okay, that's the work for all of these cases. 43:28.000 --> 43:33.000 So technically it is possible, but the devil's really in the details. 43:33.000 --> 43:37.000 Hi. Oh, that's loud. 43:38.000 --> 43:47.000 Right, you said something about if you're good at sewing, we can find a developer for you that's going to help with that stuff. 43:47.000 --> 43:57.000 If you're good at developing, can you find somebody in sewing that can help us to make patterns for free sewing? 43:57.000 --> 44:05.000 Yeah, so speaking from experience here, and we get often the question of people are good at sewing like, I can't do this code stuff. 44:05.000 --> 44:15.000 This is why I'm rolling that out as an example. I don't often get the other questions, so thank you. Yeah, the other way works around too. If you're like, I want to help, but I don't really know about this pattern stuff. 44:15.000 --> 44:25.000 We can 100% hook you up with some people who are in the other can. 44:25.000 --> 44:37.000 The slides are also uploaded on the Fauston thingy, so you can also go to codebook.org slash free sewing slash Fauston 2026 to find all the source material for the slides. 44:37.000 --> 44:46.000 And I'll also be outside after this talk. I also have goodies, so if you want that, you can come get them. 44:46.000 --> 45:01.000 Thank you so much for the presentation. I have one more question. You've mentioned the intersection of the venn diagram between code and sewing. 45:01.000 --> 45:16.000 I think I might be somewhere in there. My mother owns both a Habitatuary, a textiles shop, and she also has a huge pile of those part of magazines that you showed right with tons of really cool patterns, but they are all in paper. 45:16.000 --> 45:25.000 I'm not aware of them being digitized. Have you ever considered taking such commercial patterns and digitizing them so that other people can share them? 45:25.000 --> 45:38.000 Of course, I'm sidesteping the intellectual property rise question here, but I'm more interested in the technical challenge and parameterizing that would be another kind of warm cyber. 45:38.000 --> 45:49.000 Yeah. So, okay, so there's a few things here. First, going from paper to digital, you can just scan the pattern, right? So let's assume we have a PDF. 45:56.000 --> 46:08.000 The problem is that you have basically a binary, you know, and you have to figure out, well, what are they thinking when they made this pattern? Why is this line like this? 46:08.000 --> 46:21.000 It's not that obvious. You need people who are very good at pattern design to sort of figure that out, and knowing those people, they will probably be like, show me the finished garment that I'll just make it from scratch. 46:22.000 --> 46:39.000 So, I think it's very difficult to do this in an automated way. I also want to mention, like you said, site stepping the intellectual property issues, but I actually think it's worth talking about, because it's 100% okay to take a garment and reverse engineered that into a pattern. 46:39.000 --> 46:43.000 That's how the garment industry works, that's tradition, there's no problem there, right? 46:43.000 --> 46:59.000 But when we're talking about a pattern, you know, you're sort of like, like, people who sell patterns for a living, if you then copy that pattern, you're like taking bread and with their pocket, you know, so I'm like, I'm not cool with that. 46:59.000 --> 47:11.000 But of course, if you make a book with drafting instructions that's teaching people how to create a pattern, then okay, that's cool, you can take what you learn and implement that in code, that's cool for me. 47:11.000 --> 47:17.000 I'm not saying that, you know, everybody does what they will, but what it's about, can I contribute a pattern to free sewing? 47:17.000 --> 47:25.000 And I'm like, not if you're making it harder for somebody who makes a living selling the comparable thing, then we do not do that. 47:25.000 --> 47:39.000 Hello, thank you for your talk. I have a question because I'm like, you are about the sewing machine to do repairs and do you have any tips for that? 47:39.000 --> 47:43.000 Because I'm finding it very hard to repair stuff, it looks horrible. 47:43.000 --> 47:51.000 Here's my number one tip for sewing machines. The very best sewing machine is the one you have access to, right? 47:51.000 --> 48:05.000 Because after that, I think the general sort of understanding is that you try to buy something that is more sturdy, mechanical and less plastic in computer, right? 48:05.000 --> 48:13.000 And if you have the room for it, consider looking into an industrial machine because they're big and loud, but they're fantastic. 48:13.000 --> 48:21.000 The problem with industrial is that they typically do wanting and do it incredibly well, whereas if you're just starting out, you want a machine that can do many different things. 48:21.000 --> 48:32.000 So, you know, you start with a regular machine, and then later you have the slippery slope of collecting industrial machines, I speak for experience. 48:32.000 --> 48:46.000 Hello. So, this is really cool, by the way. For those of us who have a lot more experience to computers, kind of follows on from this previous question. 48:47.000 --> 49:01.000 Where should we start? If we've never made a gum before, but we want to get into it, obviously start with free sewing, but like any tips for like getting going. 49:01.000 --> 49:09.000 And in addition to that, how much time and investment will you expect before we've got something we could wear? 49:09.000 --> 49:16.000 Okay, so when you say where do we start? You mean where do we start with sewing, right? 49:16.000 --> 49:23.000 Okay, so my advice there actually differs from what you will find if you take a sewing class, where they will start with something simple. 49:23.000 --> 49:29.000 I'm like, pick the thing that would really, you'd be so happy if you could make that and then just go for it. 49:29.000 --> 49:39.000 And try to find, I mean, you know, within reason maybe, but like trousers are arguably not easy. Like it would be much easier to start with a t-shirt or even a shirt is easier than trousers. 49:39.000 --> 49:51.000 I started with trousers because I was like, that's going to be cool. And I got this sort of like high from it, even though they were not great, they really carried me through those initial moments of words going to be difficult. 49:51.000 --> 49:58.000 So I would say pick the thing, pick the achievements that you want to be like, oh man, if I could do that, I would feel so great about that. 49:58.000 --> 50:05.000 And then just go for it. And if you go online, you will find that the sewing community is like a super lot coming and helpful bunch. 50:05.000 --> 50:15.000 Really awesome people, there's plenty of people out there who will help you. You can also come to free sewing, there's a lot we have a discord, where people will answer all your questions and help you. 50:16.000 --> 50:18.000 Yeah, I think we'll have time for tomorrow. 50:18.000 --> 50:20.000 So what? 50:20.000 --> 50:32.000 Yeah, a really interesting thing, as someone who's actually in the intersection of doing both, it's really cool to see how you're kind of actually pulling it together because there's so much potential there. 50:32.000 --> 50:37.000 You mentioned that you really have set up so you can really combine the different things and everything. 50:37.000 --> 50:45.000 How do you, for example, with adjusting arms, how do you, for example, make sure that you're actually making pieces that fit together. 50:45.000 --> 50:50.000 Like you're changing the scope of the neckline for example. 50:50.000 --> 50:55.000 Yeah, I think if I understand the question correctly, you're like, how do you make sure the arm fits the body? 50:55.000 --> 51:00.000 Yeah, all right. So if we go, maybe it should just quickly cycle back. 51:00.000 --> 51:04.000 So we have the sort of like store, right? 51:04.000 --> 51:11.000 And this store allows us to share data between here at the top, that green box. 51:11.000 --> 51:18.000 So how that happens is we draft, for example, the front, and we store the length of the arm side seam in the store. 51:18.000 --> 51:21.000 And then we draft the back and we store the length there. 51:21.000 --> 51:28.000 And then when we have the, we draft the sleeve, we know exactly how long the sleeve cap seam needs to be because it's in the store. 51:28.000 --> 51:31.000 And then we iterate until it's perfect, right? 51:31.000 --> 51:36.000 But this also means that we need to control the order in which parts drafted. 51:36.000 --> 51:40.000 And this is also like, I didn't go into all of it here, but like we take care of all of that. 51:40.000 --> 51:42.000 Yeah, so that's how we do it. 51:42.000 --> 51:49.000 And there's no magical way because we use cubic bezzakers and there's no closed form solution to calculate the arc of a bezzaker. 51:49.000 --> 51:53.000 So we try and then we see our for a reoff and then we tweak some parameters. 51:53.000 --> 51:57.000 And we do that a couple of times until it's within one millimeter, right? 51:57.000 --> 52:05.000 And so when I move that slider on the website, but that is happening, but it's just fast. 52:05.000 --> 52:08.000 So another passion of mine is cooking. 52:08.000 --> 52:13.000 When you scale cooking from eight to hundred, spices don't work. 52:13.000 --> 52:17.000 You cannot scale linearly, you have to scale them in a different way. 52:17.000 --> 52:20.000 And I see the same problem with grading. 52:20.000 --> 52:24.000 And do you have kind of some insight to make it work algorithmically? 52:24.000 --> 52:31.000 Because often I get the picture of somebody that's say, okay, size S, but actually is not. 52:31.000 --> 52:33.000 Or well, not everywhere. 52:33.000 --> 52:34.000 So. 52:34.000 --> 52:39.000 Yeah, so we don't really have the problem with grading because we just think the measurements is input. 52:39.000 --> 52:49.000 The people who use grading, what you will see is that brands that have a large size range will typically draft to individual patterns. 52:49.000 --> 52:53.000 One of the largest end of the spectrum and one on the smaller. 52:53.000 --> 52:59.000 So that the grading doesn't need to deviate too far from the base because it's a bit like a game of telephone, you know. 52:59.000 --> 53:02.000 The further you get away, the further it gets light, you know. 53:02.000 --> 53:11.000 So then if the size range is big, like some some brands, the pattern I threw up is from Kashmirat, which is a well respected. 53:11.000 --> 53:17.000 So in pattern brands for curvy ladies, or should we just say normal ladies. 53:17.000 --> 53:30.000 And they have a white size range and I know for a fact that they actually draft two individual blocks and I grade between them to avoid this sort of like things starting to fall apart a bit when you go further and further into the grading. 53:30.000 --> 53:33.000 Did that answer your question? 53:33.000 --> 53:35.000 You can say no. 53:35.000 --> 53:38.000 And I just misunderstood. 53:38.000 --> 53:41.000 Magic formula, right. 53:41.000 --> 53:42.000 I haven't found it yet. 53:42.000 --> 53:44.000 I'll let you know. 53:44.000 --> 53:46.000 So thank you very much for this talk. 53:46.000 --> 53:48.000 Thank you.
