Hey, my name is Joseph and welcome to Monthly News number 54. This is where we recap what's been happening around One Army, our global community of people and projects working on environmental issues. Let's start off talking about precious plastic, which is our project that's all about fighting the plastic waste problem around the world. So we just got back from Lagos, Nigeria, where we helped set up a sheep press workspace in partnership with a local startup. You saw some clips in the beginning of this video about that, but I'm not going to talk too much about it because we have a full video coming out in the next few weeks. And you might be wondering, what's the sort of benefit when you guys do these onsite partnership projects? Well, it actually plays a huge role in sustaining ourselves as a team, as well as steering development for the community. So the way it works is that an organization somewhere around the world, they see a plastic waste problem in their community, and then they come to us and they say, hey, can you guys help us start a precious plastic workspace? So we say yes, depending on the conditions. And then we help pull together the project planning expertise, the machine's molds, and then do the onsite training with them to help them get started. It also affords the opportunity to do some iterative developments on the machines and even sometimes making a whole new product. And then we can turn around and share these open source with the community. And this really keeps us as the design team really rooted in the problems that people are facing on the ground. So let me tell you a little bit how this works in practice. So over the last few months, we've been working on a project with the UNHCR, which is the United Nations Refugee Development Agency, on a project in Tindufe, Algeria. And this project involves a washing system, which we've been working on, as well as a shredder basic. So we've been doing some iterations and development there. So let me show you what we've been up to. Hello. Hello. Tell me who you are and what you're working on. My name is Carolina, and I'm from Chile, and I'm working on the new version of the shredder. Awesome. So the main motivation behind redesigning this shredder, and what was the biggest challenge? So the main reason and motivation why we decided to redesign this shredder was to be able to make it ready to be C certified. And as well, one of the biggest challenges was to make it, of course, ready to be C certified, but at the same time try to keep the same kind of essence of the precious plastic machines where you can still see how it works, how like, yeah, basically the core of the machine and it's keeping its essence without hiding too much components, but still keeping it safe. Great. And can you walk me through the main changes between this model of the shredder and the previous? Okay. So first we work on the safety components of the machine. As you can see, the hopper still stays pretty much the same as how it was before, but now we added this lid. So basically this lid protects you from putting your fingers into the place and taking the risk of fretting your fingers. So then what we added to this lid was the safety switch, which basically if the lid is open, the machine will fully be off. So you won't be able to shred with the lid open. And then once you close it, it activates the switch. So then that means now you can shred. So the only way you can shred is with the lid closed. Then we have the components that protect all the moving parts, such as the steering, the coupling and the reducer. So you cannot access to them while the machine is running. Also we protected the blades from the bottom as well. So then you have, if in case you want to shred without a sieve, you have a funnel. So you cannot access the blades from the bottom either. Also all the other changes we did was the shredder box. So as you might remember before, it was welded and it was not fully made out of laser cut part. So now it's fully made out of laser cut part, it's bolted. And as well we changed the shaft. So now it's bigger. So of course it's stronger. Also another change we did was the frame. So now it's much wider, so it's much more stable. So the machine cannot fall backwards or to any side. And also as well we included some feet. So then you can screw the machine to the floor to make sure that it will not move while shredding because of the vibration or anything. Also another change we did was the electronics. So one of the main components we included now was an overload protection to protect the motor in case you put any big piece or anything. So we make sure we're never going to damage our motor and overload it very often. And as well as you can see, if you want to come closer. Now the way we wire the components, it's much more clean, it's much more organized so that anyone that want to make any kind of maintenance or work on it can easily understand it. Perfect. Can we see the shredder run? Yes. On. Plastic. We open the copper and as you can see I cannot make it work at all. So now we put the plastic, we close it, now we can make it run. Yes, and along with some other people we've been working on the prototype of the washing system. Cool. And what's the sort of main design mission behind this machine? So this machine is designed for the Algeria project where we're in a water-constructed environment, of course with the Sahara Desert and our mission was to wash shredded plastic and be able to reuse the water as many times as possible. So we needed a closed-loop water system for this. Perfect. And can you show me like step-by-step how it works? Yeah. So to start off we put the shredded plastic in one of these perforated food containers. They are an industry standard so easy to come by. And what we do then is we put it in the main washing tank. So the way this works now is that we are filling up the water tank with the high-pressure nozzles. The water level rises and in the meantime all the debris gets blown off of the shreds and then the dirty water can overflow into the filtration system in the back. So the main cleaning mechanisms then are these pressure washer nozzles? Yes. Is that right? Yes. Okay. And this is kind of blowing the plastic around in there. Yes. Okay. Cool. So that's the wash tank. So what happens to the water after the plastic is washed? What happens to the water? Yeah. So I already mentioned that we wanted to reuse the water. So we need to filter it and that happens in multiple steps. So the first step is this simple filter system that we call the grease trap. This works on the principle of oil and greases floating on top of water. So it just skims off the oil and then the microplastics that are floating also get caught in here and after that it's going to the reserve tank. Okay. In the reserve tank there is these two white hoses coming in.  So that already leaves very clean water that we can then use again for the washing process. Excellent. And can we see it run a little bit? Yes, of course. So how long does like a full process take? Like the full cycle takes 15 to 20 minutes. Let's give you an example of the cleanliness. I've got these samples. This is how it goes in dirty and as you can see on the shreds there's all this sand and other debris on it and this is how it comes out. So if you look on the shreds there's no sand and no debris on it anymore, no sticky oils. Got it. Thank you so much. No problem. So you might be wondering, where can I find these developments that you guys are doing? And that question brought up a few other problems that we've been having concerning development around the community. So first of all, yes, we have this problem of doing, we're doing some iterative developments. Where should we share this information? And ideally it would be in the download kit, but the download kit needs to align with the academy and that often goes with a build video for the machines, for example. And that's quite a heavy lift and it's not something you want to do each time you're iterating on the machines. So we needed a place that was a bit more flexible, a bit more lightweight. And secondly, there's quite some confusion in the community surrounding the versioning of the machines. So for example, the shredder pro, a lot of people refer to this as the V4 shredder. If you iterate on this design, is it then the 4.1, but really we publish this as the 0.1 because it was the first shredder pro we made. You can see it on the Bazaar, in the Discord, lots of confusion around the numbering system and the versioning of the machines. And lastly, we have this problem surrounding, there's been people who have come to us and said, hey, I'd love to include my machine in the official precious plastic download kit. How can I do that? And we thought, okay, this is a great idea, but we never really found the right place for it. So we looked at these three problems and thought of how can we create a new place that kind of solves all three. So that's how we came up with what's called the machine inventory. And the machine inventory is all about creating a place for the latest and greatest in terms of development going on in the community. So it's a place where you can go and see multiple versions of the shredder, for example, and decide, okay, which one's going to be best for me to build. And you can sort based on, yes, the type of machine it is, plus the quality, which we're defining as the sort of quality of the documentation. So how much of the documentation is there? How much has it been tested, et cetera? And then lastly, there's also a filter that's all about difficulty for building this machine. So what kind of tooling and machining am I going to have to do to actually build this machine? And we're hoping this is going to be the place that's going to really accelerate development in the community. So to be honest, we're not really sure how this is going to go. The reason we're sharing with you now is to get feedback. We have just enough out there to really explain the concept. And you can find a link to that down below, along with a guide that explains it more in full. However, we really want your feedback about whether you think this is a good idea. Any way you can see it organized differently, any other filters you're thinking about. So let us know in the comments below as well as the Discord. We'd love to start a conversation with you there. In particular, we're not exactly sure the best place to be storing the information. So we tried a few different systems, including GitHub, GrabCAD, as well as WikiFactory. And yeah, they all kind of have their pluses and minuses. So take a look, see what you think, see if you have a preference for where these files are stored in terms of the CAD, the drawings, all that good stuff. OK, I think that's it for precious plastic. Let's move on and talk about Project Camp, which is our project that's all about prototyping a sustainable way of living. So over the last year, Dave and Rita have been in Portugal setting up Project Camp and really focused on getting a base camp set up. And the base camp is all about providing the basic infrastructure, the water, the electricity to start bringing volunteers there. And actually, they've gotten pretty far. And the first group of volunteers is actually arriving in August. So it's kind of a big step, a little bit scary. Let's see if they're as annoyed with the highway noise as Dave is. And if you haven't seen the update videos yet, they're posting weekly update videos there. Check out that channel. You can find it in the description. And lastly, let's talk about fixing fashion, which is a project that's all about fixing and upgrading your clothes so that we can avoid the waste of fabrics. So since this project was launched a few months ago, we've seen a lot of development in the community going on and a few different fixes and upgrades that we'd like to share. So first up, we have an upgrade that was done by About Blanche. And they used a natural dyeing technique using avocados. It's one of the first examples where we've seen people picking up on this technique. So it's really, really cool to see. And secondly, we have an example from Adele and she's actually in British Columbia. And she took two shirts put together and made a dress out of it, and it looks pretty neat. And lastly, we have this design studio in Texas that upgraded their shorts using an old pair of pants. So again, using some leftover garments to patch together and fix your clothes so you don't have to throw them away in the long term. So please continue to share your fixes and your upgrades. We'd love to see more. Okay, I think that's it for the monthly news. I'm gonna go play some banjo in the yurt and we'll see you next time.


Labor two more home runs tonight. That's now 10 against the Orioles this season How do you go about explaining your success against the O's this year? First of all, I think the most important for me is be humble. I think it's the first thing I think I'm just prepared really well. I mean I saw I saw videos before the game I know a little bit all the pictures we face a lot So I'm just the most important for me as I'm preparing for the game just be focused and Man, just just try to hit. Are you surprised they've given you anything to hit this series just based on the damage You've already done this year against them. Yeah, I mean I'm just I know They don't pitch me really really really well and just try to be patient and and how my thing I'm just Just do my job and enjoy it is the most important the offense as a whole has been red hot this series so far How much are you guys feeding off of each other out there? We did I mean we we just try to play pretty well I mean we we all the guys have a really good communication before the game and during the game just Just we compete and and try to win all that the game possible I mean we we feel really really really well right now and and just just try to to do the mesh Do you have a couple more in yet tomorrow? I hope so labor. Thanks for the time. Thank you


Well, I could never do that, meeting improvisation on stage or off, and we're able to come back and say to them, well you do that every day because your life is an script. You've got loo, you've got loo, you've got zap, go! No matter if you're using it for corporates, if you're using it for personal growth, it just, it will give you something amazing that you can practically use the moment you step out of the conference. There's a set of tools, a set of skills, a set of exercises that help us improve how we are connected to the world and how we can rapidly understand what's going on and what can be done about it. Beautiful! Ropes. Stands. Try it, everybody! My name is Alan Karamati. Looking back over my life, I've seen three ways that many of us explore life. I'd like to go through those. The first way we explore life, I'll call self-help, or you might call it personal growth. You become in personal growth, you become dissatisfied with artificial limits to your life. Something in you knows that I have the potential, great potential to be truly free, but I'm not realizing that potential. So in self-help, we orient ourselves by our potential. In my speaking, I wanted to really share, it's a little hard to describe, but I wanted something at a meta level and at the same time very plugged in to my everyday experience. All those still little objects, the thousands of things in your house or apartment or where you're working, everything that's sitting on a surface, all the wall painting, the paintings on the wall, even the walls themselves, all those silent things that you take for granted start to sing. They make their own noises, banging, clanging, the walls are rippling, curtains are swaying and swishing, so you hear the earthquake coming. And then when you do feel it, it can have all kinds of feelings, but the first thing I noticed was like an ocean swell. The ground was raising and lowering without me doing a thing about it. Then it was more like a mechanistic thing. It was like a machine, it was shuddering, and all of this was very confusing to me. I got disoriented by this. It took me a while, it really shook me up, but after a while, after a while, I did get reoriented. I got more accustomed to the fact that the earth was not always stable. Now the benefit of this reorienting is that after getting disoriented, our lives become more free. We expanded a little bit in that switch from the old to the new. In my field, which is working with self-conscious professionals and helping them learn to enjoy speaking in public, applied improv is very handy. The second is what I call spirituality. Now I grew up in a relaxed, religious tradition. When I was a child, I learned good morals and I learned stories of great wisdom and love. But when I grew up, life seemed so much more complex and confusing and conflicted. I got disoriented. I went to the roots of my religious tradition to try to sort out this confusion and conflict, but that didn't really help me. So after getting disoriented by this, I started exploring how to explore. That's what I call spirituality. Exploring how to explore. With no assumptions, no beliefs. It had such a deep effect on me personally that I realized, oh, this is where it's at for me. I need to be doing something that helps people reach the kind of transformative abilities or whatever, the benefit, transformative benefits that I've realized. The third way that I see that many of us explore life and that I've experienced personally is by participating in the arts. The actress, Glinda Jackson, said it really nicely, acting is not about getting dressed up. Acting is about stripping bare. The most powerful art I've experienced has been really transformative. It clarifies something that's in my experience, a relationship or you might call it a presence. If all of it boiled down to one sentence, the takeaway would be... What we experience in improv is really key here. Only in spontaneity can we be who we truly are. True spontaneity sets us free from our old orientations. So we can explore life.


Everybody for us here being six twenty twenty three Bowman chrome choice boxes for Jeffrey H. Thanks Jeffrey Let's hit a banger here Yeah, you're right. You are right worse. That was a way worse All right first woman base auto at on Sanchez start there Green Lob first woman auto Diego Mosquera 1099 Nice color there looking card and some blue here blue ray wave.

Get those out to you


All right, welcome friends. Welcome YouTube viewers. It is summer stride and our final nature boost with our amazing partners. And we just cannot say enough about them and they will be back. We have something scheduled a nature boost schedule for October so stick around pay attention to our calendar and you'll find out what it is. It's going to be fun. But if you're not busy later today, come back for a Spanish language craft program, and you will learn all about mono printing. And this is at 2pm, and by the amazing artist colleagues to robles, and it will be in Spanish, and it's a great class and he is a great artist so don't miss this one. And he will also be back. Oops, I got those backwards. So this Friday and next Friday, 2pm. Today is three reduction printing. So it will be fun still. And like I said, this is part of our summer stride programming and summer stride is not just for kids. It's for all ages. So do your 20 hours reading and get that amazing iconic tote bag there with the art by Kailani Juanita. We want to welcome you to the unceded land of the Lonie tribal people and acknowledge the many raw Mutush Lonie tribal groups and families as the rightful stewards the lands on which we live here in our beautiful Bay Area. Our library is committed to uplifting the names of these lands and community members from which we these nations with whom we live together. And I encourage you to learn more about first person culture and land rights, and we'll put a link into the chat box to a great reading and resource list. On Saturday at 2pm, we are celebrating the life and legacy of Janice Mericatani. And so please come out for that all of poets. The lineup is stunning poet laureates past and present. And some reading campaigns we have coming up total SF on August 24. We're talking about the end of the Golden Gate book with Daniel Handler and Gary Kamiah. And I don't know if many of you know but San Francisco Public Library has a reading campaign called on the same page. This is where we encourage all of SF to read the same book. And we are reading Jacqueline Woodson read at the bone, and we will have a book club on it. So check out our calendar, and Jacqueline Woodson was just in our virtual library yesterday and you should go find her on our YouTube channel because it was such a great combo. August 18, the Chronicles film critic longstanding film critic he's been the film critic since the 80s. And he has the his first book out in 10 years from heyday books called dream state California in the movies. Oh, one of my favorite human beings in the whole world, Shanta Nimbark shark shark off, who is huge in the food movement here in our Bay Area, and she was part of the people's food system. And she's also the co owner and co co founder of other avenues. Other great stuff I'm going to breeze through these we have still a lot of stuff happening for summer stride. So you should come out. And today I want to introduce you to Jessica Lee, the education program director at the native plant nursery. And she works for the Golden Gate National Park Conservatory and we are so excited for the tour Jessica. And I'm going to turn it over to you. Everyone welcome Jessica. Thank you so much. We're super excited to be a part of this last nature boost of the summer and excited for the future nature boost to come so hello good morning everyone. As mentioned my name is Jessica Lee I'm the education programs manager at the native plant nurseries in the Golden Gate National Parks, working with the Golden Gate National Parks Conservancy. And I go by she her pronouns, and I'm really excited to share about the, the Presidio native plant nursery, and the work that we do here at the nursery. But before we get started. Thank you, as a feel for that lovely land acknowledgement I also want to acknowledge kind of like the relationship that as native plant nurseries like with this land and acknowledging again like these lands are the unseated lands of the Ramaytish alonee, you know this land that we work in, breathe in, recreated, like live in. We call you Yolomu here. And that was its original name Yoloma before it became known as San Francisco as we know it today. And we acknowledge like the intimate relationship with land and intentional stewardship that has been practiced on this land of four thousands of years by the Ramaytish alonee, which was disrupted in the 1800s. When Western settlers came on to this land and change the relationship with people in land since then. So now, you know we are going through another change in the National Park lands and trying to like you know bring back those relationships between animals, plants and people, and just want to honor like the Ramaytish alonee for like that stewardship, and really want to honor the current native folks who are here on this land who are thriving connecting and doing so much for their communities and encourage folks to look into the actions that indigenous communities are calling for and forwarding here. So I'll turn my camera around really quick just so you can see, we can see the Presidio native plant nursery kind of in type here. And so, since we might have folks of all ages here who might not know what a plant nursery is. I like to kind of go, go through it backwards. So starting from nursery, you know what my people think when you hear the word nursery.  So together at the plant nursery with a place who take you take care of and grow plants, primarily younger plants. And the plants that we're growing and taking care of our native plants. So these are plants that have been growing in like in the San Francisco Bay Area for thousands and thousands of years in whom with whom the Ramaytish alonee have had a much longer and intimate relationship. And then we are in the Presidio parks so all together we're the Presidio native plant nursery where we grow and take care of native plants for restoration projects throughout the Golden Gate National Parks. So as a caveat, we are not a commercial nursery. The plants that we grow are all for various restoration projects. So happy to walk you through how that works. So follow me on this beautiful gray San Francisco summer day. And we'll stop by our kind of first structure since most many plants that we grow start off as seeds. So I'll take everyone to see our seed lab first. So walking this way. You also have some volunteer group here who is doing some important work with us. And we'll might have a chance to talk to them some more later. So walking in this way for coming into our seed lab and I'll flip the camera around and walk slowly so you can kind of take a peek at our seed lab. So here's let me try to get somewhere where the lights a little better so feel free in the chat if you just kind of want to put in what what are some things you noticed in here in a seed lab in our seed like how is it similar or different to kind of what your idea of a lab is. So, again, as I mentioned in most, like, you know, most plants start off as seeds and most of the seeds used in our nursery operations are actually collected from plants growing in San Francisco. We have folks whose jobs are seed collectors. If that sounds something really interesting to you, yes that is a job and it's super fun you go out and hike around our park lands and San Francisco lands to collect seeds from the plants.  So we do collect from the land since we want, you know, to use that genetic material that DNA of those plants that are in the wild to kind of continue growing plants for the park lands. And it's project requests each year that inform us on how much Steve we need and what species we should collect. And so, when we do go out to collect we get in order to support the wildlife and maintain sustainable practices and the genetic diversity. We generally don't collect more than like 5% of the seeds from any location just so that those natural processes can still continue on the park lands. So, after we collect them we bring them back here, because in order to grow those healthy plants and prevent the seeds from rotting we clean the seeds in our seed lab. So it can be some kind of more simple cleaning including like here you can see we have this seed or agonium latifolia. And then we don't when you let me go out to collect the seed, it's really hard to collect it seed by seed it's small and it's not super efficient. So often I see collectors will go ahead and kind of take the whole in fluorescence or like kind of the whole part of the plant that holds all the seed which might include you know some part of the stems or things like that. So part of the cleaning can include just kind of like separating the seed from the rest of the plant material. And here you can see we have these civs, very gold rush era, and we use it very similarly where it kind of shake and rub the seed into and the small seed will fall through these little holes to the bottom, but all the rest of the plant material stays on top. So that's kind of one of the simple ways that we do more simpler processes in terms of seed cleaning. We also do different seed treatments to so for example seeds after the clean seeds can be put into dry storage in the refrigerator, you have these are refrigerators. Sometimes they're put into cold or wet stratification or you put the seeds into, you know, like, we put the seeds together in a little layer of sand or peat or soil so they can start germinating. Or sometimes these are just sewn as soon as they're collected. So the different treatment of seeds depends on the different species. So what that treatment is is that we are like kind of copying natural processes. So there's something that these have like the have called dormancy. I'll turn around my camera so you can, you can have a face to the voice. There's something called dormancy. It's a little bit like hibernation. Many commercial seeds actually have had dormancy kind of like, kind of bred out of them. But since we are collecting seeds from from the park lands, these people have dormancy is a little bit like hibernation. It's either kind of like a physical or chemical dormancy that keeps prevents the seed from germinating until it is the right time until there's like a good time for seedling survival. So for example, let's say a seed has like some seeds, the way that they kind of wake up or like from that dormancy is kind of experiencing winter. So sometimes we put the seeds into kind of a cold or wet stratification in our fridges because it kind of mimics a winter in San Francisco and that's kind of what gets the seed to wake up so that when we take it out and get ready to germinate. It thinks that it's been through a winter and that it's springtime and ready to grow. So it's kind of it's kind of like mimicking processes in nature and kind of tricking the seed to wake up from its dormancy. So some of the other ways that we sometimes treat seeds for the, for their different dormancies, depending on their species is we have these sandpaper covered blocks here so what do you think this is mimicking in nature. Feel free to put it in the chat. I mean, this is mimicking in our San Francisco lands. So yeah, so some of the seeds especially our sand dune species, the seeds, they don't start germinating and they don't kind of wake up from their dormancy until they've been sufficiently kind of scratched up by the sand that naturally occurs with the wind blowing along the beaches and the sand blowing over the seas. So for some of the species you bring them back here we kind of scratch their sea cope with the sandpaper blocks and once they're scratched enough. That's kind of what wakes up the seed and gets it ready to germinate. Another treatment we have going on here is that's a little more unique is we have. It's not a very pretty site. But this is a blue witch nightshade. It is in the same family as a tomato family, the nightshade family and so for any of our gardeners who are watching watching and might not know and might know that that one of the ways to treat tomato seeds and get them ready to germinate kind of go. It's a fermentation process that kind of copies the way that you know the fruit around the sea might, you know, rocks and ferment in nature. So we have this going on here. And some of the other kind of more unique ways that we might kind of depending on the species that we might wake them up out of dormancy and treat them is, you know, some of them we might actually put them in like coffee, give them a coffee treatment. What do you think that copies and mimics in nature. It mimics kind of like going through the digestive tract of an animal. For some of you that's what kind of wakes them up from dormancy gets them ready to germinate that kind of acid. And then for others, some of them they what wakes them up from dormancy is fires for a long, for a long time wildfires were a natural part and as well controlled fires that were practiced by the indigenous folks here. And we're a part of the plants process, many plants processes. So we're some plants, the seeds, we kind of we use smoke to be used to set them on fire now we kind of use more like a process of like using smoke to wake the seeds up to get them ready to germinate. So now that we've kind of talked about feed, I'm sure you all are ready to see the seed actually start growing into plants. So, follow me we're going to go into some of our growing structures. So we can left this way into our atrium, and we'll head into our mist house, where, like where we have our youngest plants that are just growing from seed, but before we can go in, we actually have to do something really important. As nowadays with with COVID we there's practices that we do to keep each other safe such as, you know, very careful with pathogens or germ plant pathogens that can get our plants sick and one of the pathogens that is really impacting a lot of California native plant communities is phytophthora. I'm trying to say that three times fast phytophthora. So phytophthora is a water walls, and it is often travels in fact on kind of like the water and mud and dirt that gets on our shoes. So just to make sure we're not bringing any pathogens into any of our growing areas and first kind of kind of use this scratchy thing to take off the dirt off my shoes and open up and have these foot baths are filled with a solution that kind of sanitizes the bottom of our shoes. So I'm going to step on it. And with that, there's no phytophthora coming in and welcome to this house. Hi Jessica, your, your, your videos frozen, or something, or pause we just see the foot scratcher. I restart the video. How's that. Hmm, still just a foot scratcher. You still with us Lisa. I mean Jessica.  Let's see it becomes back on. Let's see, let's see, because you're coming through loud and clear. Yeah, that's so strange. I just want to say that I'm not that viewers. I will say something with an issue that is our signal is not there. We have some days that are better than others off a when it comes to our signal and why it's by the year. Are you still in the mist nursery. Yes, still in the middle. Maybe we have to step out of there. Did you turn your camera back on. Yes. Yeah, we're not seeing anything. I see some wheelbarrows. Okay, so the dead spot is the mist house. So I'll kind of show it from here. Hopefully folks can see. Let's see. Maybe can folks still see this. We're seeing. Yes, we're seeing some tables. Okay, great. Awesome. So I'm sorry we can't get a closer look at the mist house. Here it is. So, once the seeds are treated, the small seeds that go into a flat filled with like a peat moss type mix. And every flat, every flat excuse me can contain more than 500 seedlings. Big seeds like acorns are so directly into pots filled with soil usually one at a time.  I don't know if you can see but you can, you might see some colored tags in there so those tags they help us keep records and understand like when they were planted what the species is, and sometimes like the information to help distinguish soil or genetic variability. So what we have in this house is it kind of provides the perfect environment for the seedlings that has shade and humidity, and each bench has its own irrigation system to keep flats and pots and nice and moist, which is what they really need at this stage. So, the downside is that this moist environment while really good for seeds and seedlings it's also perfect condition for fungus plants. You might see these yellow sticky traps so we use those to try to capture the fungus net. And then another way to keep insect pests away is like we add sand on top of the flat so you might see from here like you'll see kind of a lighter color on top on the flat so that's saying that also helps keep insect pests away. So, I'll try to get a nice pan around. So, yeah, so this is on this house where we try to give our seedlings kind of like the healthiest and supportive start to a plant life. Awesome, so I'll close this and then we'll step into the greenhouse. Jackie one of our amazing nursery technicians hello who's filling up with some of our amazing soil we actually have a kind of like a tailored soil mix that we create to best support our plants.  So the soil that we mix we make sure encourages maximum drainage so that it's not kind of super so the roots don't stay super soggy. Okay, so here's a greenhouse. I'm going to test and see, let me know if the video goes off but I'm going to see. So folks can get a closer look at some. Here. I will flip back so I'm spraying my shoes. Is the video still working. It is not. It's a little, it's a little, a little jolty. And your voice is going out. How is this. Those plants were. Yeah, that's good. That's good. Okay, I'm sorry for so I think I think this is I think this maybe this these are the plants who are not wanting to be not wanting to have close up today. Yes, exactly. Yeah, they're they're messing with the signal. So we don't get super close up to them. But yes, here's our green house. So you'll see it's kind of attached to the mist house through that door. And this is the second step for many plants. So after the ceilings grow, they're kind of transplanted into individual pops, like you see here. And they're moved here, especially in the summer months will kind of like our a big growing season and transplanting season. So plants in this area they receive extra detailed care you can see this is like a more controlled environment in here where we can monitor them closely and perform any needed treatment. So for example with that toy on there's been a lot of a lot of various different insects and things going on there so this helps keep it more in a controlled environment so we can do some some of those treatments for the toy on. Yeah, so this is like, so this is this is a greenhouse. And so I'll close this back up just so we can keep the environment in there nice and warm. And we're going to take a little pause and kind of like the are growing structures. So I can kind of show some of the other important spaces we have here at the nursery. So back here in this building. This is our have a terium and it's kind of our gathering space we have. Because not only do we work with plants but something we're very passionate about is also working with people in connection with nature and plants. So we do. So during the school year we do host school groups. Like where students can learn about plants and the environment and make while we mainly serve elementary school aged classes. We also have like pre COVID we had year round service learning programs. Unfortunately, we do have more limited capacity this coming school year but excited to excited to say that we are. We are transitioning back to trying out some in person programs here again so then teachers are interested you're welcome to email nurseries ed at parks conservancy.org. And then, in addition to education programs we also host volunteer programs which you saw some of those volunteers earlier in the tour. I'm happy to talk a little bit more about that volunteer program in depth when we head over there, but as a heads up just also want to say that things are also a little up in the air. In terms of volunteer programs so for the latest updates you can check out our volunteer page on the parks conservancy website, or you can also contact volunteers at parks conservancy.org as this for most up to date information. Coming back over here. On this large building. So we call this building the pot palace or the palace of fine pot. So as you might have seen we grow a lot of plants which means we use a lot of pots.  You can see on this side these are all dirty pots over here this is where they're dropped off for reuse after the plants have been planted out and we have students and volunteers kind of helped clean them. I would also want to highlight an amazing partnership we've had with the San Francisco Conservation Corps, who's been helping us out with a lot of the nurseries work that's been going on, especially while our volunteer programs were much more or have to be cut during the height of the pandemic. So they've been helping us with all kinds of tasks like transplanting, like seed cleaning and then especially kind of the pot washing and treatment so thank you SSCC for all your support. Couldn't do it without them definitely check them out they're a great group. So, like this is where they're kind of clean where you use power washers to get them to get the dirt off. Again, we want to make sure we're not bringing back by top row with these pots so we clean them clean the dirt off of them as best as we can. And behind this curtain that is actually where we have our heat treated pot. So that's kind of the final stage to make sure that they are pathogen free. So how exactly do we heat treat these pots that we have. I'll show you and also say kind of as a note of like you're really thankful for all the work that goes into helping us to use these pots as well. They are plastic pots and so I know for some nurses who don't have that support in terms of volunteers or, you know, they don't have the skill conservation for they use the pots once and have to just get new ones because they don't have that time or staffing to clean and reuse the pot, because we want to use sanitary and clean pots when growing plants. So really thankful for folks we can help us kind of lesson our kind of plastic footprint a little bit so that we can reuse those pots. So that kind of under wraps over here, that is our steamer. And so that steamer is what we use to kind of heat treat not only our pots but also our soil so we can make sure that our soil is pathogen free as well. So as you can see it's kind of a whole operation going on here. It's very much about kind of best practices to make sure that we're kind of creating the kind of like healthy as supportive environment for our plants to growing. So yeah under that, like under that those that cover is a large boiler on wheels, and he's water from the host to create the steam. And so we can control how much fresh air is mixed with the steam in order to achieve a certain temperature so it's usually 140 between 140 180 degrees. And then that steam and so we use that seems to kind of help sanitize our pots and soil. So over here we have our propagation shed and that's where we have a lot. You know a lot of the work done with our plants so we have a lot of transplanting going on things like the cleaning and other tasks so we have this set up going on over here. So we can see some pots with soil, filled soil that are ready to get transmitted into we have the steel table that are really easy to sanitize again so we can make sure we're keeping our plants healthy and pathogen free. And over here we have some volunteer extraordinaire who are helping us clean seed, and we also have our steam generator here next. So at the end during QA have any kind of technical questions or have questions about like the volunteer experience we can definitely check in with them. But right now, as I mentioned some of that seed cleaning work that has to be done so they're doing kind of some of that more involved ones for example you can see here. There's some folks like literally kind of taking the seed out of the seed pods and separating the pots from the seeds. We also have some folks kind of separating the seeds from these kind of grass seed seeds over here. Yeah so like really fun if you're really into kind of like detailed small detail fine motor skills kind of tasks. So now kind of to our last growing structure over here this is kind of the last steps about our plants. Go to before they are planted out into the park lands this is our shade house. You can see it is by far our largest structure has 42 tables or benches in here of plants so and each bench can fold more than 2000 individual plants. They are definitely pretty full right now as well because there are some big projects we are planting for folks might have heard about the tunnel tops new tunnel top site in the Presidio a lot of these things are being grown for tunnel top. So again, for going I'm scratching my shoes, making sure they're nice and clean by using a foot bath. And then stepping in. So here you can see the plan. I kind of if I were to kind of use an analogy like miss the Miss House is kind of like plant elementary school where they're getting all they need to kind of get a healthy start to life. The greenhouse is plant middle school, you know where we can still kind of give them a more controlled supportive environment but they're definitely getting bigger. So the Miss House, I kind of think of the plant high school, we're kind of giving them still like a safe environment but also to kind of grow a little bit more independent. So as you can see the structure looks pretty different. We use a 30% shade cloth here rather than kind of physical walls like we do in the Miss House and the greenhouse. It also allows things to come in like more sun, wind rain, you know, more of the elements while still kind of creating like a safe barrier for the plants, just so that they can get more like the spaces they'll be planted back to. So that way they're kind of growing a little more resilient so that when they're planted out they have a higher success of surviving once they're planted out. Since they live pretty cushy lives as the plants when they're in the Miss House and greenhouse. And we have so many plants of species to care for in here so definitely plants in the Shea house require the most attention. So they need pruning watering fertilizing weeding and much more. And around the fall season after the first year reign that's when the plants usually kind of leave in our street and are planted in the park at specific restoration sites. So here's the image before we can get a closer look at some of these tags here. So here we have some classic California poppy. And so here's the tags we have, if they can focus, you can do it. Technology, I believe in you. There you go. So as you can see, we have the scientific name at the top, and then you'll see a series of like numbers and letters in the middle. So that's the Propagal Code, or a kind of like a barcode number that follows a set of plants all the way from the seed, or when the cutting is first collected. So the first two numbers. So 18, that's the year that the seed was collected. So this seed was collected in 2018. And so the letter is the nursery name so we have three main nursery sites we have Presidio, Marin Headlands and Fort Funston. So that key means that it was collected by Presidio nursery folks. The next set of three numbers is the sequential kind of identity given to each new species collect collected in that year by that nursery. So in other words, this says 2023. So this is the 23rd species that was collected for that year. And then for, and then you'll see a letter, and it says, and so that indicates that it was grown from seed cutting or something else. And the final number says how many times that batch of seed has been used. So you'll see S. So that means I was grown from seed, and it is the sixth time that plants have been grown from this seed. So that so we have that record that for each of our plants so we can have all that information there, and you'll see an S followed by a date so that's the stone date so this seed was so December 5, 2020. And then the last time I was transplanted was December 15, 2020. So these have these have been in here for eight months. So, like, yeah, so again here here, we have many different kind of plants being grown here. I wish, like, you know, these are our nurseries while, you know, we don't have kind of the drop in volunteer programs that we did pre pandemic, you know this is in national parks so this is accessible to the public. So I'm also curious and kind of just want to take a peek at these plants. You know, you're welcome to kind of come on come on by and see if any staff are around, or just kind of walk around on the outside of the Shea house and kind of see what plants we have growing over here. So I'm happy to like so happy to continue kind of showing some of the plants for growing in here, and then as well as opening it up to any questions I might might have come up in the chat. This is so cool Jessica, thank you for showing us around. What kind of my question is like, what kind of education did you have to get Jessica to be so knowledgeable about this are you a scientist. Oh, great question. So I do not come from a science or environmental science background. As education program manager I definitely came through more of the education route. So I did some I went to school for elementary school teaching. And then before kind of falling into environmental education, I didn't even know environmental education was a thing. When I was like when I was in school. So definitely I think you know it's like I've been really fortunate to find myself here and I like all this kind of plant knowledge that I have was definitely learned on the job by some amazing colleagues who definitely have either more of that kind of technical background or who also learned, learned hands on like years of nurseries experience. It seems very, it seems very scientific. That's great that the public can stop by I love that. And how many there's just one missed house. And yeah so we have. So we have one missed house, one greenhouse and then the shade house here. Sometimes, you know there are sometimes or maybe it's like, you know, for example at the procedure nursery just tunnel tops is such a huge project that you know we might not have all the plants so sometimes that's when our other nursery site can support and kind of providing some extra space so some of our tunnel tops are some of plants are our Marin headlands nursery right now as well. But we have those three nursery sites mainly. We grow mainly for the projects for the park lands kind of in that area so our Marin headlands nursery grows mostly for Marin and North Bay Park projects, prosidio for mainly prosidio and like San Francisco sites, and then Fort Funston grows also as well for some San Francisco sites and then for our kind of like San Mateo sites as well so that's generally how the kind of the plants and the projects are divided between our nursery sites. Interesting. We have a question. I'm done with my questions now how about our audience. What source, what water sources do you use for the plants. Oh, great question. So we do, as you can see we have. We do have sprinklers and hoses everywhere. So yeah we're connected to kind of the water system in the prosidio park, and happy to check in with Annette who might have kind of more exact questions on that, or, or answer to that question. Like, but yeah it's definitely water is a big definitely a resource that we use a lot of to kind of water our plants so that's definitely been kind of a conversation as well of like the water, the water usage that we take up knowing that it's a drought year while also trying to keep our plants alive and cared for. Yeah, that's a great question. Okay, how about how many different plants. Oh, sorry. I was like, Annette, do you have. Yes, do you have an answer to like where our water source is. Yeah, so a lot of our own water source. Oh, sorry, let me take out the microphone. Okay, hi. Better. All right. Can you hear me. Yes. And so a lot of the year the city has its own water source, which is the Lobos Creek, which is right between the city and the Richmond neighborhood San Francisco, but sometimes during the summer, actually I think almost every year during the summer. That creek runs dry, and we switch over and start to have the same water as the rest of San Francisco. So we tap into head to head as everybody else does. Thank you Annette. That's really interesting about the creek. So next question is how many different plants do you have in the nursery. How many different plants do we have at the nursery right now. I can take that one. Yeah. So we grow and there's there's about 400 species of native plants in the city. And usually on any given year we grow about 150 different species. So within that 400 total will grow about 150 just depending on what's requested for that year. Oh, I think you're on mute. Yes, I am. So some good native plants for SF folks to grow at home if they don't really have a green thumb. Yes. Good. What are some easy native. California poppies, they do love to grow kind of anywhere they actually love to be neglected. So that's a good one. You know strawberries, we do have a lot of strawberries that are native and those will take over and they can also be grown in pots. Thinking about what can be grown like on a balcony or something. We also have some native succulents. That's the kind of plants I grow the kind you can neglect. That is fascinating. So I recall there being a native plants sale is that something you do. That is not for us. I think that you might be thinking about the Golden Gate Park. Okay, that's just a, that's a city from heart versus ours. Okay, here comes another question. Do you stress plants with wind, like a hairdryer to get them used used to being in the wind. Oh, good question. I wonder if you can see how windy it is here now. I swear it's been windy. So we grow the plants in the shade house because the wind just goes straight through there. So the shade, the shade cloth does provide some protection from the wind, but for the most part, it's the plants have to same with the rain and sun. The shade house just makes it a little bit less intense for the growing plants, but everything is done. Cool. That's a great question. Thank you audience. All right, do we have any final questions for our friends here at the native plant nursery? Thank you for this tour. It's been so exciting to see and to see our friends there doing some work there. Yes, thank you. This was super, super fun. I'm glad we could be a part of the SFDL Nature Boost summer series. Yeah, absolutely. And let me just check the YouTube side and make sure there's no more questions. Everyone in our YouTube land, good questions. Okay. Jessica education coordinator. Thank you so much for being here today and taking us on this tour. And we will look forward to our next event that we can do with our partners. I'll give you a hint. It's in October and it contains a very cute animal. So look for our SFDL.org slash events. And we want to thank all of our partners at NPS, the Golden Gate National Park Conservatory and the Presidio Trust for joining us this summer. And Jessica, thank you. Have a lovely weekend and SFDL community. We love you and we'll see you out in nature. Bye everybody.


All right, let's check this one out cool. Yeah, the door works a lot better. Whoa. Oh, I like it. It's great It's up in there looks around Just make sure as we continue to polish that every time you move The head that there's some form of connection on that neck now If you want to tilt that neck over this way a bit if there's a way to rotate a bit Bit of involvement in the in the chest It just feels a little bit like it's caught up at that top joint and then the edges moves around and that's it It's a tricky thing was you want to be subtle you want to be not too cartoony because it's a bit more of a somber moment, but you could experiment with slightly bigger arcs if you track the nose The nose feels pretty straight And you can do maybe a slightly bigger arc See how far you can push that before it breaks So cool for polish stuff You know during things like this it feels like the door is sliding against the fingers you can start working on Better contact points. So when he starts moving his hand down There will be a post change in the hands couple frames before that and it's gonna be a post change through here So it's not always In that curl position it feels like this the fingers would almost intersect with the door at this point And then watch out the hands You can see this on this elbow the hand goes back the whole arm and then Boom, it's a very hard edge here. So it was a linear key On your hand on the arm translate. That's an ik Same here. It feels like the whole hand just rotates down But then the fingers are not compressing against the door. So the shot looks great So you can start going into these types of details I think this works a lot better It's cool and the hook up is great with the neck shot Yeah, that's great Watch out for something like that just for polish. Just how slowly that thumb goes down for the grip So it feels a bit slow and even No So you can probably get to there a bit faster You start working on offsets so that not all the fingers move at the same time as they curl out there Sorry some Trucks drying by here. Sorry. This is a temporary setup So the sound May not be the best in the world Probably one of the worst in the world Same thing here finger details Watch out through here. The rotation of the wrist is kind of staying the same. You can probably Change some tilted towards us and see the top of the hand And then as it comes down it flattens back down stuff like that. I think you're ready Shot to bring the stuff like this and the facial stuff Yeah, that's definitely better as well They got your separate finger movement and some intersections But I think in terms of what's going on and what you want to do with it. I think that's great You start working on your on your transitions second when he when he gets to here And he goes back down it still feels I'm sure you're totally aware of this. I'm just mentioning what I'm seeing again Um, then he goes down in a very simple arc, you know as he goes down There might be a slight rotation in why you know, you know, everybody's either lefty or righty Mostly a righty So there might be some latent something in there how someone sits down Maybe that he's always used to sit down on his left or right butt cheek You know stuff like that give it some texture. So it's not just a straight down You know, he goes straight down and goes straight down his chest as well So that could be a bit of a slight adjustment. So once he sits down here Could be kind of a side rotation on the butt cheeks and twist in the body just to kind of reposition Nothing huge but just enough to make it a bit more complex I don't think you want to do a big impact on the head But it could be interesting to see how far it can push that as well So that the head is a bit higher sits down is a little bit of impact on the head Just for the physicality. Um, it might be too much but it would be worth exploring. I think The same thing here he goes back into it feels like all the rotation Um joints, you know the head the neck and the and the chest are rotated back in one axis only So just start getting into a bit more complex stuff Probably involve the chest a bit more if it's like the chest goes back a bit I know it's for breathing or just kind of straightening But kind of following the head a tiny bit again, if it's just 10 it's fine just so that You always want to feel that if this the head goes over there Well, it's going to affect the neck in this way It's going to affect the chest in this way. It's going to affect the hips So that will affect this that will affect this that will affect this but obviously it will be diminishing right so the strength will fade out of the How much influence it's going on here Stuff like that you can you can get into it now The idea is in the timing all that I think it's great Getting into the the nitty gritty of All the transitions don't forget to involve shoulders as arms are moving And you can play around with as he goes this it's just kind of like that Is he resting maybe his head a little bit on that? On that wrist so when he goes forward is there contact? So you will see some pushing of the lip and facial structure here Is that going to push down the wrist as well? You know like stuff like that you think about how complex you want to make that Cool, and if that makes a shot couple frames long, that's fine too. I mean that's to me. Um, that's all up to you Alrighty, that's it. Thank you All right, there's an email you can sign up you can start whenever you want you can submit whatever you want You get 16 submissions either way the like and subscribe would be awesome. All right. Thank you


You're just checking this and let's jump straight into it. This indicates the level of decomposition you want in the wavelet transform. The following modifications to your code will integrate wavelet processing. This is just one of many thresholding techniques you can use for denoising. You might want to adjust this or offer multiple options. The wavelet used for decomposition, wavelet transform, is directly obtained from the client request. You should ensure that this is a valid wavelet type supported by PyWT, e.g. DB1, DB2, R, etc. Consider adding some error handling or validation for this. The level parameter is also directly obtained from the client request. Again, you should ensure that this is a valid value. Too large a value might result in an error or undesired behavior. If you wish to use wavelet coefficients, further analyses or visualizations, you can extend the code accordingly. The above example just applies to denoising. We also have the outputs. Make sure it's the correct MID. I want to do some error checking first. Let's pop this. Okay, we do get an error. This is not the type of error I was expecting. Do we get it? Even if I remove this? No. Can we print out this list? Why copilot doesn't want to work? Is it doing something? We can just do that, can you? This is the list. Okay, we need to adjust this dropdown. We actually have names. Let's pop it back into GPT. The list you've provided appears to be the wavelet names supported by PYWT, and the log entry suggests that a request was made with an unsupported wavelet transform value, UWT. Are any of them legit? No. Given this, it seems that the validation code is working correctly when provided with an unsupported wavelet, UWT, the server responded with a 400 bad request. That's fine. Here's a modified version of the earlier code to achieve that. How do we update this HTML bit? Can we update this? Wait a second. Should we correct responses? UWT? We want to update this with the violet wavelets. We need to clear that. Run this. This is the violet wavelets. Shall you understand the context? Okay, updating the value, this value. It's not a valid value. Okay, let's try this. It should be updated. It's not giving in there or now. Okay, we might add more later. Should we do it now? Because we'll forget later, wouldn't we? Okay, give me the DB3. Yeah, there's good feeling of them. Okay, let's just add four. That should be enough. Okay, you know what to do, don't you? It's the same two. Yes. Right, and it's enough. A biotogonal command-kit-up co-pilot. Why aren't you doing it by yourself? It shouldn't be. How should it? Ah, there is no 1.2, so thank you for that. 1.4 and yeah, there's 1.1, 1.3, 1.5, and 2.2. Okay, we'll leave it there for now. Oops, add this. We need another input 4. Let me check. Let's make this one default HTML. Okay, how do we do this? Give me something. Yeah, kit-up co-pilot. It's either I don't know how to use it or it's absolutely hopeless. One sec, what are we doing? I missed this one. Well, problem can be make the default option spell. Yeah, kit-up co-pilot can learn from chgbt how to modify code. Yeah, just need to add the word selected there. So, now we have db1 as default. Now, obviously this should change the signal. Okay, this stopped working. Okay, what's up? What's error before fix? Can you fix this? The error message indicates that the variable eGunDiscordator is being used before it has been assigned any value. Specifically, the line. Save this file as well. What was the last change? So, this line is doing what? Is attempting to pass eGunDiscordator to the pywt. Yeah, what do I have to do? What do I have to do? So, line 87 it's not indicating any problem. It starts the thing. It's working okay. When I hit Wavelet in Noise I get this error only when selecting Wavelet in Noise is on and this is the error. Can you give me more specific answer if Wavelet in Noise is over there? What's the problem? Yeah, it doesn't have an else function. Let's try a co-pilot that's doing something. Let's do some manual printing coefficients. Why? Okay, error handling is good. Let's do some more error handling. It should help try. Okay, so instead of Okay, now the app is having an error. Don't have else yet. Okay, so this is running okay. Why is this not sending this? What am I doing wrong? What am I doing wrong? What am I doing wrong? If Wavelet in Noise is just be reverse multi-level discrete Wavelet transform. Yeah, this doesn't make any sense. Now to fix the code. Sorry, no super long prompts. I'll probably get a timeout soon. Just trying to understand what's going on. Okay, so we have the we have this error. Okay, so we have the error. So, we have the error. We have the error. We have this. Right, so this should come first. Yeah, I don't want any comments like that to look obvious that that's the continuation of the code. Where is if do we have if the trend? We do. Okay, now I'm really confused. Yeah, let's just check in finance. Should go eG data and the trend if necessary then removing check in finance and then weather denoising rest of the code. Okay, let's try this. So we're starting the thing. It's refresh. This is working. Okay, that's working. And it's actually doing something. So it's removing some noise. This is actually only useful up to a very limited point. Let's reduce the window size. Yeah, so you can see the noise reduction there. So yeah, the 4 does know something about eG. It's a particularly noisy channel. This is the trending. This filter orders only. Yeah, we need restructure. The whole thing could actually just let's try this again. Yeah, I want to know how to so on the larger screen ideally everything will be set from left to right on a smaller screen on a tablet of phone. Yeah, it's obviously will have to go top to bottom. But otherwise it's actually working. It's actually doing something useful. So next thing we'll be patching it up a bit and publishing on the side. So it will go instead of this one here, we'll probably put it up top there. So it will eventually look at least as good as this one, if not a much should be much better. So hopefully you'll be able to test it yourself. What's it going? Yes, this levels in HTML should be limited levels value should have a mean and max like that ID would zero just be the same as having it off and default about 2 Yeah, there's not much difference between the different types. Now the other thing is when I change the frequency spectrum is updating as well. It's good. It's changing by by the role Yeah, the question is this is now with no errors Now that the immediate issue is resolved, I would recommend periodically reviewing and refactoring the code for performance, maintainability, unreadability. Moreover, always consider adding more comprehensive error handling and logging mechanisms to make it easier to diagnose and fix potential issues in the future. So the thing is so we did that the effect the noising is not very clear. Let's see what it says maybe definitely knows way more than I do. Okay process Okay Okay That looks, sounds, very interesting. Can you give me the details? Certainly, the thresholding method you use in Wavled denoising can significantly affect the results. The method you are currently using is known as the universal threshold. Adjusting it or using other methods can give different results.  You can adjust the multiplier, currently 0.5, in the formula to see if a different value gives better results. Should I have it as an input? The PYWT threshold function has a mode argument that allows you to choose between soft thresholding, default and hard thresholding. Soft thresholding shrinks coefficients that are smaller than the threshold towards 0, while hard thresholding sets coefficients smaller than the threshold to 0. Another commonly used threshold, especially for signals with Gaussian wide noise, is the Minimax threshold. This threshold can be estimated as... Sure, shrink is a method that aims to minimise mean squared error, MSE. It involves a bit more computation, but can sometimes give better results than the universal threshold, especially for signals with non-Gasian noise. Bayes shrink is another adaptive thresholding method that's based on a Bayesian framework. The main idea is to estimate the threshold based on the variances of the signal and noise. It requires additional computation, but can be more robust in certain situations. It's often beneficial to experiment with different thresholds and thresholding methods to find what works best for your specific dataset and application. Visualising and comparing the denoised signals with different thresholds can be very useful. Also, remember that it's not always about achieving the cleanest signal, but rather preserving the important features of the signal while reducing the noise. Oh, you're so smart. Okay, let's add a multiplier. We might continue this next time, but yes, we made quite a bit of progress, but denosing actually works. I assume this number should be between 0 and 1. Yeah, Github compiles as 1 or 2, but yeah, it's definitely the original thing was 0.5.


Sure, you know, we want to encourage, especially in educational institutions, we want to encourage an embracing of the technology. We want people to grow and learn and move forward with the technology. But as that happens and as we have less and less control over the servers and the end points where people are collecting data, we worry about how to make sure it stays safe. This is not really any different. You have to approach it, you know, with the right sort of contract.  So I don't think my concerns are really any different than any other cloud model that we might choose. And so we have a lot of concerns about the cloud. The mobile device brings with it another aspect in that, you know, now you have something that is much more easily stolen or lost. So we look at mobile devices and we say, well, this is great and I can get my corporate email. What if there's FERPA data on there? And what if that's your personal phone? So one of the things that we created was a mobile wipe waiver.  We need a waiver that says that we can wipe your device right there on the spot. Really, your first and best defense is a great education. You've got to train people. You've got to get them worried about it. I think Gartner just quoted $214 per identity that's lost. And so you look at how much liability you could have just on a mobile device that you don't own, that you may not know is even in your environment and where that's going. So one of the things that we've done is we've come up with an online security course for all faculty and staff. And as we move forward, as the cloud becomes more important to people, as new technologies become more important, as they become more mobile, so do we become more ingenious about how to make sure those things get protected.


If you look at saints, Christian saints, have you seen a painting of a Christian saint smiling? No, that would defeat the idea of a saint. What makes you a saint is not helping other people. If helping other people made you a saint, then no gates would be a saint. Then Carnegie and Morgan and Rockefeller would be saints. The great entrepreneurs and industrialists in Korea would be saints, because they helped other people. They changed the world. They made the world a better place for millions and billions of people. Businessmen are saints. But no, they're not saints. Christianity doesn't think they're saints. Why? Because they benefited from helping other people.
