Here we are at Think Tech Hawaii Studios in downtown Honolulu, and I'm Wendy Lowe. I'm your friend as we journey to take your health bath. We are coming to you live every other Tuesday, so I get one Tuesday off, two Tuesdays off a month, so that helps me a lot because I need to find more great friends like I have right here today. I'm going to introduce you to my dearest friend, my dearest newest friend. So today our topic will be on a discussion with Helen Hayden, and as you recall she was my host and guest along with our director of the station, Jay Fidel, and I just want to say she's back, alright? And so I was watching over when I was in San Francisco, and I was so excited that Helen and Jay had such a great time, and I said you know what, I want to have some fun with my friend, and so I said Helen would you come back today and share your journey because it was such an impactful journey that I need others to really realize, you know, Helen looks like the perfect health, epitome of perfect health. Always laughing, always bubbly, and just dynamic in every day. As soon as you wake up, I mean we were together until like midnight last night, bubbly as heck, having a great time with life, but we're going to dive right into her heart and her life, and she's going to show us a little bit about what she truly experienced. And so I want Helen to share with us her journey towards wellness and optimal health because she has a great one, and we're still on that journey to get her to better and more optimal health. So our takeaway from today's discussion is that you too can take your health back one day at a time. So joining me today is my newest best friend, my BFF, Helen Hayden, welcome Helen. Thank you Wendy so very much, it's an absolute joy to be with you today. Thank you so much for asking me to be on your show. Again, again, but mahalo for being on the show today, and you know in life there are no coincidences.  So can you bring me some joy? I was leaving this think tech studio and this hapahali girl comes walking in and I'm like, hey, and we say hi and we give each other a hug, and I simply ask you, what are you here for Helen? Yeah, it was such a weird day. I was not even intending to come to the studio. My show wasn't coming until later the week, and so I came early and I met you for the first time and it was like we knew each other our whole lives already. Yeah, instant, instant, yeah. And we have been inseparable and had so much fun and it's been so much fun getting you involved in some line dancing over in Nashville. Oh, I know, I know. Yeah. Got my cowboy outfit on, I got my boots on, you got your boots on too. I got my boots on. And what you called them? Oh, dance boots. Yes, dance boots. Dance boots. That's not what I heard you call them earlier, but road stoppers. Yes, road stoppers. And so I prayed and I asked for somebody to just bring joy into my life and more fun. And she told me what she wants to do in her professional career goals. And one of them is that you wanted to start a nonprofit for vets. Yes. And I said, hallelujah, you are my next best new friend. And then we got to talking about other things. And then she says, yeah, and I lined dance. I'm like, you what? And that was, that was history from there. So we've been going to line dance. Yeah. Like on Mondays. Yeah. And you know, this show is called Take Your Health Back with Wendy. And so that's part of taking your health back is doing the activities. Absolutely. And line dancing. I mean, for two hours, we dance from seven to nine. And it's free. It's free. So I mean, being Korean, being Chinese, free. Free. What a deal. Right. The best price, free 99. So we walk in there at seven and we get on the floor and they give us lessons. Well, Helen doesn't need any because she's a professional.  But for us to newbies, and I invite all of you down, just come and partner with me because I'm there and learning each song in each step. So partner with me. And when you get better, you hang out with Helen. And for two hours, that's what we do. Yeah. And it's a great mindfulness exercise because I tried the traditional mindfulness practice though. Yeah. I don't do that. Yeah. I don't do that very well.  No, I don't do that kind of mindfulness. My mindfulness is on the dance floor. Yeah. Five, you know, two hours solid dancing and just really spending time with quality people. You don't have to drink. It's a bar, no smoking. It's by the water. It's beautiful. Come down to Nashville's Waikiki and Aloha Tower. They moved years ago and just come be part of us, Monday nights and Friday nights.  Line dance. You're not partnered up.  And so there's no real physical contact unless you want it. But that's an option, right? Yes. And so we get in there within the first 15 minutes. We're like sweating already. We're working up a sweat. We're being very physical. And that's part of wellness, being and doing the activity and not just sitting down all day on the computer watching TV. So that's part of it. And I really want to encourage all of you because we're giving you an open invitation. Absolutely. Come on down. Helen is the best host. The teacher there is Donna. Donna, Donna. And I tell you, but enough about that. So Helen, just reintroduce yourself to the audience. Sure. Tell us a little bit about Helen. Sure. I'm 51 years old.  So I've been a disabled vet since my early 20s, you know? And I started having health challenges then. And when I hit 40, I became diabetic and had hypothyroid issues, started getting sicker more often by the time I was 45. I had two heart stents. People thought for a long time for a year. They thought I was just having panic attacks.  So they stented the two heart, two heart stents. And then as time went on, I started having more problems, ischemic colitis, you name it. It's been crazy. So I just want to show you, this is my bed at Tripler. I swear, I think they have my name on it. That's not a happy thing. That is my most funniest picture because I'm like, you know, to be vulnerable and share some of these pictures with the audience, it's me with no makeup, it's at my most vulnerable time. But I want people to understand when you see people out walking about, you don't know their journey, what they're going through health-wise. You just don't. I present very happy and healthy and bubbly, like you said. But underneath it, I'm still going through medical challenges, right? But you know what? You take one test at a time, one step at a time, one diagnosis. And one thing I learned from the VA mental health side, we'll talk about later, is the diagnosis is not you. It does not define you. It is a condition that you have to learn to overcome or deal with. So the second slide I want to show you, this happened this September. This was my latest and greatest. It's me with Bell's palsy. You win. You win.   And I couldn't believe it. I thought I was having a stroke. Exactly. It looks like a stroke. It does. Went to Tripler again. And sure enough, they tested me for stroke. But I had a neurologist that said, if you can do this, this is fine motor skills, it is not a stroke. And he says Bell's palsy is very common, especially when the weather changes here. He sees an increase. And a lot of people don't know what Bell's palsy is. Right. But it's a seventh cranial nerve. It gets inflamed. It's all this is. And I took pregnant zone. And wow, I was super blessed because I got cured, obviously. Right. But it was scary. Right. I know people that that has stayed with them. One third, I was told, get worse. One third, stay the same. And one third, get better. Wow. I was super blessed to get better. Wow. What age were you at that time of the onset of the Bell's palsy? This was this last September. I was 50. 50. So the whole idea when I started talking with you, a lot of your health challenges came about when you turned 40. Absolutely. And we all know that life changes at 40. I mean, from the site, you're nearsighted for our site. Everything kind of just changes. The weight doesn't go off as easily. And just different health challenges. So knowing that out to the younger audience, I believe at this generation, it's starting even younger. That is 40. And so we really want to get out the message of people starting to be healthier and take your health back earlier. Not wait until 40, because even for myself at 43, I noticed the weight didn't come off. I felt a little bit sluggish. And I thought, what's going on? And I prayed. And I said, I need help. And that's when I started changing my lifestyle. And I was 43. And that was 16 years ago that I made the health change into my whole lifestyle. And so I really want to encourage more. Not wait until we're 40. You younger generation out there started at 30s. Even like diabetes, huge. You sit on that board and you know the challenges this island faces with diabetes, right? Process foods. I can tell you a quick story. A couple years ago, before I came to Hawaii, I decided to change my life. I did no processed food. I drank water. I walked two miles a day and danced three nights a week. And in four months, I lost 55 pounds. And reversed my diabetes. But as I get older, like you said, the weight doesn't come off as easily. I got sick, gained some weight back. Now I'm trying to work my way the other way. But it's just getting early testing, getting early detection, awareness, education, absolutely. Right. And you know, you hit it right on the nail right there. You know, although you're diagnosed, you don't have to accept it and live with it. It's not your life. So exactly what you said Helen, you were diagnosed, yes. But you then, you dealt with it. And then you did, you took some action. You danced. You danced like there was no tomorrow.  You laughed. Absolutely. And then you did it yourself as a healing process, along with the physical activity that you endured. And then you changed your diet.  And then are you diabetic free? Not yet. Not yet. Not yet. I'm working on it. Yes. And so with the weight loss, I will get diabetic free. Yes. I know that is to come. Right. My heart, I'm having some more challenges. And that's okay. Worst case scenario, we'll face it if and when it comes. But that's one thing that I learned throughout this health process is don't go internet searching for answers and diagnoses because you'll find tons and just listen to your doctors. Too much sometimes. Do the test that's in front of you, you know, and work your way through the process because you can really scare yourself. And that's what I did originally, but now I trust my care team. I have a whole team and we just take it step by step because we spend so much energy and time on what is that it could never, what if it isn't? Right. We don't think like that. We think what if, right? Right. And so now I just want to encourage people, just take it slow, take it one step at a time. Exactly. And even if it's worst case, like I could be facing open heart surgery. Even if it's worst case, I have support. Right. I have my, you know, my Ohana family here. I have my son and daughter-in-law. I have John. Everybody's here to support me and I'm not walking this walk alone. Right. And that's the other thing line dancing did. It gave me a community of support. Yes. Ohana. Yes. Ohana family. Yes. And they've just been phenomenal. And they check on me. They always make sure I'm going to be there. They ask about me all the time. It's a wonderful feeling. Right. This is the type of caliber of people. Right. I mean, that's the, everyone knows that we all need a buddy, a buddy in life, whether you have a whole line of buddies or a buddy, someone that holds you accountable and that you can hold that person accountable as well. It doesn't have to be a boyfriend or a husband. It can be a best friend. It could be a coworker, that you could just, you know, that knows you well enough that if something looks different about you, they'll recognize it. That's right. And they'll say, hey, are you okay today? And that's what we all need to do. It's really just take time to build on these kinds of relationships. Because if not, who's watching out for who? Right. We're so busy living life and wondering what if. So we really need to stay tuned to ourselves and people immediately around us that we love and we care for. Yeah. And be honest with the people that you're around, right? Say, hey, I have these challenges and these struggles and this is what I need from you. If you see me start behaving or acting this way, you know, to try to mitigate or lessen, especially in a public setting. Right. Because I know as a disabled that I face some challenges publicly that I have to be kind of cautious about. And so I tell people around me all the time, I'm very honest and say, hey, you know what, if I start getting a little agitated or anxious, get me a glass of cold water and say would you like something cold to drink? And I found that that grounds me and it comforts me. So you just work with the tools that you have. That's so important, Helen. You've defined knowing and getting to know yourself and that's so important because a lot of times we're so busy, we don't even know the signs of ourselves. So how can we share that with others and how can we even detect that in others when we are not even mindful of ourselves? So that's very, all these little tidbits out there listening, write it down, watch this video again because you're going to learn so much from Helen Hayden. Looks perfectly bubbly, young best best friend here, but there are some still hidden issues that she's dealing with. We're going to dive more into that as we return from our break. We'll be right back. Aloha. This is Winston Welch. I am your host of Out and About where every other week, Mondays at 3, we explore a variety of topics in our city, state, nation and world and events, organizations, the people that fuel them. It's a really interesting show. We welcome you to tune in and we welcome your suggestions for shows. You got a lot of them out there and we have an awesome studio here where we can get your ideas out as well. So I look forward to you tuning in every other week where we've got some great guests and great topics.  So I'll see you every other week here at 3 o'clock on Monday afternoon. Aloha. Aloha and welcome to At the Crossroads. I'm your host, Tisha King. You can catch me every Wednesday alive at 5. I'll see you there. Here we are with Helen Hayden, a returning and soon to be a host of her own show again. But we're so excited because she has a health journey that really wanted to bring to you again because as I keep saying to my best friend here, she looks like the epitome of health, cheerful, always smiling. But inside there's still some health challenges that she needs to face and deal with and conquer. And the main thing is that she's aware of these things going on within her and she's making a change in her lifestyle and changes that I'm so happy for you about. She's doing the actions and the activities, which is physical activity. She goes out line dancing two to three times a week for two to more hours a night and that's exactly what we should be doing and it doesn't cost anything because it's at Nashville's and it's free and he has a good time. And he has a Ohana support system, a line of buddies around her to get her through the night to just put her in a great spirit and a mood so the next day she even starts it off a better Helen. So welcome back Helen. Thank you Wendy. Yeah. So you know I wanted to just share with the audience what is your ethnic background? I'm half Korean. My mother's Korean. I was born in Korea. My father's a white boy from West Virginia Army and I traveled and then I joined the Army and never thought for a minute that I would ever become a disabled vet. I was a dental lab tech in the Army and when I asked people what kind of disabilities you think a lab tech gets and I don't have any of those. It was not about that. Basically my challenge just started with the military because I was misdiagnosed. I was not treated for endometriosis which led to very big complications down the road. For the grace of God I have my son but after six months after he was born I had to have a complete hysterectomy and it was army negligence. Wow. And so that helped start the journey of understanding my benefits from the VA. Right. I had a service officer that helped me and educated me. They took me under their wing and really helped me in my journey so for 25 years I've been a veterans advocate helping others just passing it along. That's what attracted me to you. When you told me I want to save a vet a day I'm like whoa, you're my best friend. I found my buddy because that's the area that I really wanted to address as well and with your passion and your knowledge and your experience I was just so blessed to receive you as a friend and I know that this is just the beginning that we're going to make headway with the vets and making their lives more purposeful. Yes, definitely. That's your heart as well. Definitely because what I found is I've been on Island since August of 2016. There's a lot of misinformation out there and I tell everybody you know go to the source va.gov the websites are wonderful but I wanted to show them in case they did not know to go to the VA Pacific Island healthcare system. They call it the ACC that's the picture of where we all go to get the healthcare that we need. The big pink building but it's on the left side of Tripler when you face Tripler you go around the corner there's a parking garage across the street and that's where you that's where all the healthcare is taken care of and a lot of people get very confused because there's two components at Tripler for VA that's the healthcare side then they have the benefits side which is the next slide in the E wing and that's where you go and that's when you first come up the hill pass the gate guards and you take the left you can't go any straighter you take the left at the end and it's the first right right there it's the end of the building it's the first thing you will see it's E wing that's where the benefits side is and that's where the service organizations are and that's where people need to go to get educated on benefits I tell people all the time VA is great don't get me wrong but these service organizations American Legion Disabled Veterans Purple Heart Wounded Warrior you know VFW they're all there the state of Hawaii they can help them educate them on their benefits help them fill out the paperwork and if something goes wrong then they're there to advocate on their behalf if you go to the benefits side it's you and the VA you don't have that advocate with you so I highly encourage everybody to get an advocate so you know when you go there to either side the lines must be very long yeah and take a ticket take a seat kind of concept hurry up to wait yeah hurry up to wait sometimes you wait three or four hours I've been there with clients that've waited a long time they're doing the best they can with the staff that they have and they are hiring all the time the VA has wonderful help they have wonderful you know packages for employment and they have employment fairs all the time keep your eyes peeled they hire 30, 40 veterans at a time to one of those I went with him and I watched the process it was they screened him they took his resume he got offered a tentative job in two hours flat and within three weeks he was already working at the VA it was amazing process well they're looking and that's the need is there so they need to fulfill that component so they can process more and get these veterans what they deserve the benefits that they deserve as they defend our country yeah and it's a lot of people don't understand that if it's in your medical records you've already earned it now we just got to put the pieces together to make sure that you understand that component and on my show when I do voice of the veteran I'm going to walk people through the step process on what they need to gather and how to approach that that part of it the veteran benefit part of it and maybe I'll have some guests that can explain it yes so starting on the 7th of April at 3 o'clock I get every two weeks I'll be doing a show from me from May 7 and this is my show is a little bit different I really want to hear the voice of the veteran this is our show the way I look at it I'm just the host if you want to be on this show and talk about stuff please contact me at the show and I'll gladly bring you on this is ours services we lose them so if I tell every veteran please no matter what experience you have don't take no for an answer let's try to find a way to make it work let's work with the staff there let's make sure that you get the health care needs that you need taken care of and that brings me you know we talk a lot about physical stuff a lot a lot of people don't know if there's a whole another side and so I just want to touch quickly Wendy you know a lot of people will talk all day long about their physical stuff but the minute you want to talk about mental health you want to clam up and shut down this is not a thing of shame this is not a thing of guilt or embarrassment we have 22 veterans a day dying from suicide we need to start talking talk therapy has been phenomenal for me I'm not saying everybody works but for me it worked the medications did not it was zombie land I aided that it took away my personality so I worked with my providers and said I can't do this is there anything else sure enough talk therapy and I have learned that this is I don't talk enough but I learned that I like talk therapy because it helps process you know with all the health issues that you faced being in the military and being a military family I know your therapy was self induced and it has a lot to do with the ability to share to reach within and share the good the bad the light and the dark and so that's really critical so you have that gift many people out there they can't they can't share their shame or they're just they just don't know they're confused they think it's their fault they don't understand what you're going to bring to the table what you are bringing to the table when you return back to your show is yes give them a voice let them speak out and then you can help them and direct them in the right path to get healed absolutely absolutely because you know I find that a lot of veterans once they start talking it will all come out right but they just got to find that person that they trust right and that's the big key I found therapy that I trusted 16 I was going through another divorce I was a hot mess but you know what I got connected with the VA mental health went to Day Hospital after that Dr. Rob over there was phenomenal after that I went to this program called the Empowerment Technical Empowerment Centers of Honolulu it's at the VA tons of skills tons of support and you know I just can't encourage people enough to utilize these services don't be afraid they even have guitar lessons for veterans and probably hula they do yoga they do art therapy it's not what you think anymore it's not like the old school VA this is amazing dynamic programs yes but and I know we've talked about this before and a lot of people they're not patient so they go in and they want immediate response and like oh you know I get tired of waiting and I don't have time to wait but they do have time to wait it's a process it is it's a process and you know we just have to encourage the listeners out there that if you know of a loved one that is experiencing loneliness or PTSD or just anything that they are looking for services and they don't know of that's out there for them please tune in to listen to Helen's show and you know send me questions you know for the show email me send me questions I would love to just read what you write but one of the things we did a great segue into the last slide because this number right here please make sure you get this number 1-800-273-TALK and if you're a veteran press 1 anybody can call this family member civilian if you have a veteran in your life that is in crisis call that number if you are a veteran in crisis you don't have to be suicidal or homicidal but they will ask you the first question because safety's first for you they need to know and you need to be safe no matter what but I personally have called that number when I have insomnia when I am stressed out about my health issues when I'm stressed about my relationship issues I call that number they are always on your side wow you've got another but this is what it's all about so you know Helen you've been very privileged to understand what services are out there so you tap into that and so the other part now is you want to give back and you want to make sure that they receive the same that you had and so there's one more component of your life that I really want to dive into I know that you're on your health journey so your mind body and soul you know you're working you're working on that and now what makes Helen happy that's the next part of continued healing what makes you happy and what are you going to do now that you're this chapter of your life and you're going to close that part and you're going to dive into another chapter sure I'm super excited so I am going to fulfill a lifetime dream of mine and start producing kimchi yes everybody giggles and laughs but I got to tell you my mother made good kimchi but I make better but I kimchi queen is being launched very soon in the future and I'm super excited because it's a super food and it aligns with everything it aligns with everything that I'm doing and when people eat my kimchi the shredded especially they seem to love that one when someone comes up to you and says this is the best I've ever had in my life you made a difference in that person's life yes and that aligns with what I really believe in whether it's through veteran care whether it's through sharing food sharing line dancing I want to give that person that gift that I got right that amazing feeling of just wowness yeah and so that's the whole thing when you eat your kimchi you're not just even eating probiotics you're eating all her love and everything her mana is coming out into this kimchi that's going to go into you and so you're going to be joyful happy and bubbly just like my buddy over here so but you know Helen time's up we just talk for two hours and it's done right now so we have to say bye-bye to all the audience and just thank you Wendy thank you so much BFF wing movement wing movement so we'll say goodbye to you and we'll look for you on your show on Wednesdays on Tuesday on Tuesday at three o'clock three o'clock so we'll see you then hello everyone


Hi everyone, Joe for jaspyscasebreaks.com coming at you with our last random number block randomizer for this group of teams We can finally open up our first Panini one football. Very exciting. That's kind of come up in a separate video First let's do this big. Thanks to these these wonderful people here for getting in on the action. There are the numbers right there Let's roll. Let's rando one and a six seven times one two three Yeah, I could sign the back of those it would probably increase the value of those moran's Brandon Hall down to Roy after seven and After seven times right here one two three four five six and Seventh and final time after seven times three down to one. I Don't want to search those numbers. I want to copy those numbers Ryan Case and you made your wife watched some some bro breakers. What up, bro? I Mean I can do I can do I can do it like that if you want to but maybe Maybe Mrs. Ryan case would not let you hang out with us anymore if that were the case Brandon with three Chris with zero Jeremy 33 with six two threes make a six Patrick with nine TJ with two Robert with eight Ryan with five Sean with four Chad with seven Roy with one Sort by column B right there by number and coming up in a separate video will be the break itself. We'll see you for that


This session we are going to have three talks of 25 minutes overall so you have 20 minutes for your talk and about five minutes for the question and at the end of this session we'll have a 30-minute discussion where all the panelists will be, we'll have the possibility to answer a question from the audience. Right now we will start with, you'll be five minutes late but we are going to start with the first talk from Obina Abak from Queen's University Belfast and he's going to talk about quantum thermodynamics and quantum control so Obina you can please share your screen and I will let you know five minutes before the end of your talk about the remaining time you are so whenever you are ready please start. Is the screen full now? Yeah you have to put it in full screen mode. Okay perfect. Just don't see you. Okay it's okay. We can see you. You should share only the application. Stop sharing and relaunch the application. Okay. Okay. Yes. Okay thank you the organizers and thank you for the invitation to present part of my current research in the subject of quantum thermodynamics and quantum control. So today I'll try to give you a brief overview of what I've been doing in recent past and then I will start first by trying to give a brief motivation why we are interested in these kind of subjects and then I'll make a brief reminder on false truth or to refrigerator you are trying to you are motivates what we already know from your first or your third year summer physics and then I'll try to now bring up the idea when we have control in the system can we generate a better performance or not and also I will give you a second application of this kind of quantum control called shortcut to adiabacity. So if we look over the years the technology have done gone quite remarkable in downscaling sizes of our electronic devices for instance we are all having smartphone or tablets and this in the seventies used to be huge mainframe devices but in principle all these are limited or the challenges being faced by every of these electronic devices and our laptop is mainly how best can we manage the heats and as well as increasing the processing speed and the same when people have been trying to minimize these engines up to down and it was only in 2016 with the group of Ferdinand Keller Schmid Keller in mines that were able to downscale a functional heat engine auto single atom regime so in the last year a group in brazil here in this here this is the NMR experiment where they show that you can actually realize a an auto in a quantum heat engine by having an RF here which pumps some heat into the code but by doing some work this is just a short proof of principle experiment and they are able to show that yeah they can get efficiency up to around 0.44 percent and if we look yeah no 44 percent and if we look here we see that they have to be some time limit which must be exceeded before you the engine can actually perform a useful work and the implication of what this can be used are quite enormous and one can think several of application for instance in quantum computers or sensors and also in a number of places like nanotechnological application so let's look what is actually a refrigerator so it's basically any device which performs some work which you extract some heats from a cold bath to a hot bath and then in the process of adding some work and they cannot efficiency with this with the ratio of the input heat up on the output is given by this is given by this temperature ratios but the one of the problem is that although is maximum performance it is actually slow but for a real engine things happen in finite time and this actually leads to dissipation and one way to characterize this is always what people regard as coefficients of performance at maximum figure of merit so depending on what you choose as your figure of merit so and then if we take that the performance and then as well as the cooling power at a finite time then we'll have a expression that depends on the ratio of the temperature and let's say look now on the if we look at four stroke engine we can just think about our thermodynamic subject you have a piston and a gas you compress it you do some work and then you shine some laser which exchange heats so and then add some energy and then you can push the piston back and then put it in contact with a cold bath and then this is a typical engine cycle and if we perform the analysis like this for instance using a quantum framework in a weak coupling limits we can actually do the same so like you have an ion trap then your modulates your frequency and then your couple shine some laser lights and your modulate backward and here during the change of the frequency or the size of the trap then there is a q star here which tells you how fast or how slow you do this adiabatic process so we can compute the performance exact in this scenario and that is given by this expression here where this q star tell you how fast or slow you drive the process and when the q star one and two is equal to one that means that the process is quite very slow that's the adiabatic regime and in this regime then the performance of the refrigerator is characterized by the ratio of the efficiency the ratio of the frequencies and then if it's greater than one the performance is always less than what you obtain for the adiabatic scenario and let's look at the plot here you can see the blue line is the efficiency the coefficient of performance at the maximum figure of merit and then the dotted dark line is the cannot the cannot coefficient of performance that's the maximum you can achieve at zero power and the red and the green ones this is when you now start to yeah in drive this in a finite time so you have some non adiabatic effect and then you see that the efficiency or the performance reduces so then the question is is there any way we can actually improve this performance of this engine in a finite time so we need to take some control and why would do why do you need this is not only an application that is necessary for thermodynamic engine but it has been quite useful in other areas of yeah modern physics critical systems and then metrological protocol and then also circumventing the coherence in a system so let's say consider one of the known way of doing this which is called short cut to adiabaticity and this is basically when you just a kind of a slowed down a fast motion video so you start a process you start a process for instance you look at the plot then we want to end at the same point where it will end in adiabatic situation without minding what happens in between and then if we look at the first question here then what it tells you is that we need to construct additional Hamiltonian which will suppress the non adiabatic transition during the driving protocol and by giving some bounds that your frequency need to fulfill then we can actually construct yeah this kind of protocol for be it two level system harmonicus later for the case of harmonicus later then we can actually have expression that looks in this form as our additional Hamiltonian that if we put it with the original Hamiltonia it will ensure that we suppress the adiabatic adiabatic contributions however the question becomes what about the cost of this additional Hamiltonian and how do we see it so one way to look at it is like for instance if I now consider some instantaneous power analysis and do this then this tells me that maybe if I'm looking between around two and eight it will appear as if I'm not really yeah doing any work or maybe I look two point five and then eight points around nine point five or so then but if I want to know my actual power I have to compute what we call in electricity the average power and if I take this analogy and then apply it here I can actually compute what I have a definition for the cost of my driving and then this mean the cost is actually also in the same form which we used to characterize our be it refrigerator and other thermal devices and then if we compare this with what we call the non adiabatic work then we see that this in a very short time the blue the red line is greater than the gray which is the non adiabatic work that's the friction so in a very short time it is actually very huge cost to perform this kind of a share shortcut protocol but there is actually a good range of time where you see that it's quite lower than the work friction so if we now come back to the analysis of our refrigerators and then we put the cost in the definition of the performance so we can then compute yeah the cooling power yeah in this form and then the dotted black line is the adiabatic situation then the red is the shortcut protocol and the blue one is the non adiabatic situation and you can see actually that in a very short time that it doesn't you doesn't gain anything by doing the shortcut protocol but between the intermediates which intermediary job then you actually have a reasonable advantage and for the cooling power then this you also have advantage than the doing the non adiabatic protocol and therefore the analysis on this is looking at the figure of merit we choose and we see here that for that figure of merit that you can actually have an hierarchy which tells you that although the shortcut protocol is lower than the adiabatic situation it is always greater than the non adiabatic situation provided that you are above the region where this time is greater than the time where the costs of doing the shortcut is greater than the costs of the friction so that tells us that we can simultaneously enhance both coefficients of performance and the cooling power then we now look at the green plots here we look since we are talking about time and the quantum mechanics tells us that there is limit to the speed of evolution of a system which is usually called the quantum speed limit so we can use now this framework also to try to get a kind of a bar a tighter bound on the performance of our shortcut protocol and if we use this expression here due to an adan and the Aranov the boss angle the ratio of the boss angle between the density operators and then the with the mean energy of the associated with the shortcut so we can actually get a bound based on the quantum speed limit and that's the green plots here and we see that this is always higher than the sda and likewise also when you look for the costs no the cooling power so more information on this you can see on this article yeah recent article here with Mauro Paternostro and then very close then the next part of the talk or net upness application of the sti I want to present to you is like yeah we consider one of the system you have two system we know in physics are basically the harmonica oscillator and then two level system and for these two level system what happens when we bring two of them together and this is quite relevant for range of experimental platform be it's a cavity QED like found in the mass plank and the other places around the world and then also like the superconducting or sacred QED and then this yeah fine so and then as well as the linear ion trap so and this is well described by a well-known Jens Cummings model so where this is the describe your harmonica oscillator then this is the two level system and the coupling between the two and this can be have a transition yeah between the state different levels and the resonance you can actually complete complete a perfect transfer from your ground states n plus one to the end of the excited state at some time but this is not possible for all n at the same time so what can we do with this then what we set out to do was to generate a non-classical state using this kind of framework combining it with this shortcut protocol and one way to go about this is like first we know that we can map this to a Landau-Zener problem form where you have something that look like your sigma x z and then sigma x where these are the spin operators and they would with this in mind construct the shortcut to a debacteristic protocol and that you can do population transfer in a finite time and if we now use this framework we can actually construct different kind of non-classical states let me just give you example of one of them here so which is like one known important one called the Schrodinger cast states so the idea is that we start with a fork state then we make a pi over half pi over two posts and then you perform the STA protocol and we can concatenate this into many times and after that then it makes a measurement so if we do this then you measure the system let's say we start yeah for instance here we want to go from this to this yeah zero plus two states then we'll say that we actually have the state at a very high fidelity why if we do this with time independent protocol we get 0.08 so this scheme offer large improvement on the fidelity so in conclusion I have a try to show you here the refrigerators efficiency can be better if we do shortcut protocol and then I show you that quantum speed limit also impose some bounds on performance of quantum machines and cooling is not always equal to power so it's always good to look at the overall performance because of whenever you do this kind of a shortcut protocol and then the last I also show you that we can combine the shortcut protocol and James Cummings model to generate non-classical states and this is quite robust against noise and many imperfect pulses as we study so with this yeah you can see more on the reference yeah about this to work me one is this on the refrigerators yeah publishing the fiscal review research and for the parts on the state engineering that's this year PRL here with Ricardo Puebla and Mauro Patanastro so with that thank you for your attention thank you Obina for this nice talk anyway within the time limit thank you for that now if there any question I've seen on the chat that Ali has a question if he cannot mute yeah thank you Steve thank you Obina for this excellent talk I have two questions the first one is in one of the slides you showed a theory for the auto cycle for a quantum harmonic oscillator is what changes in how it is number two is way to extract the amount of dissipation for a thermodynamic system but how much do these results change when you go down to you know smaller scales okay if I understand yeah the first just I cannot yeah really go back okay yeah the first one is about the cycle of the auto this one yeah so here what's here is the system is closed yeah in the first part of the protocol so yeah and then for this particular situation we are considering yeah so this is just a kind of unitary evolution so when you couple with the lights so this is the quantum harmonic oscillator yeah the quantum harmonic oscillator yeah in this case but I guess my question is if you had and harmonies yes let's say if it was not harmonic how would this change you if for what would change basically yeah you have a higher energy in the system yeah probably and then yeah what's another thing is that when you you do the the open side when you couple the reservoir so depending if you are in weak coupling limit so far the study so far what has been shown is that you have basically what still looks more or less like the linear one except that now you have modification in your performance both at maximum power so because you have putting more power and then these changes yeah them you have your performance at maximum figure of merit looks like I say one okay then the second one is a yeah how the energy changes yeah for this small system yeah in the experiment we are with the 2006 yeah with the color what we find is that when you scale actually the energy so the amount of energy being produced yeah by this and then a kind of a try to scale in the sense that by dividing by considering the per kilogram so like you check the performance of a car and then the performance of this kind of engine by the weights of the medium that's performing the cycle then this is just by a difference of around 10 between the two so if you check it just by the yeah okay the weights yeah efficiency per weight and there's no much difference yeah between the two the only difference yeah we start we can play around here is that maybe yeah we can start to think about doing some yeah like using some quantum approach like using like squeeze light can we get more by doing this instead of just coupling yeah ordinary thermal reservoir okay thank you thank you okay thank you Abba there's actually another question but I will ask Mathura to hold that question and prepare it for the discussion session slightly later you want to try to be on schedule for the next talk of esterina


360, 3D, 360, virtual reality camera for the X... It's very special, so who are you? So my name is Shachar Binoun, I'm the CEO of Humanized Technologies and we're very proud to announce today, here at the CES Unveiled, the Views Camera, a product that we've been working on for more than two years. So on each side is two cameras? Basically we have here eight full HD cameras, capturing a stereoscopic 3D, the entire sphere, meaning that the zenith, the nadir, everything, the entire sphere, all the way up, all the way down, everything. You can't get away from it. Those cameras don't shoot the same direction? Is it a little bit different? Because each camera has a vertical field of view of 180, so we capture the entire sphere. So it's fisheye a little bit? It's fisheye, we do the fisheye correction, fisheye distortions, and then the white balance, and then the exposure, everything. Everything inside? No, the process is done on a PC with a one-click button operation. So everything is recorded but you need to render a process? A screen pops up, you press on one button and it's done. Have you considered trying to process it inside? It's a gigantic amount of data in order to have a amount of processing inside. It's a lot of processing inside. FPGA is something... We have FPGAs inside. You already have, but what do you do with them? Basically, we're not doing the processing inside. There is some processing done inside, but the stitching software, proprietary technology requires a lot of processing power. But the processing time is at video rate, meaning that if you shoot a one-minute video, it takes only one minute to process. So you can do it real-time? So we call it video rate, it's not really real-time, it's at video rate. Why can you not just stream it? You can stream it from the computer. So you could actually... So you can. You could do it real-time. You could rely. Not from the camera itself. Okay? So why can't you make it live? You can make it live once it's connected to your computer, but not from the camera itself. So this is just a mock-up right now, no? This is just a mock-up, but actually the red camera, the yellow one is a real camera. Let's just bring the yellow just one second, because there you have an example where you could just have it on a table with a pod. It looks exactly the same. And how soon is it available? And when can people buy it? We'll be ready for pre-order around March, and we'll be ready for shipping around August. How much? Because? The price would be well below $1,000. We don't have the exact price yet. As soon as we finish the logistics and the other cons, then we'll determine. But it's going to be well below...


If you want to stick around, we'll do the Q&A. I'll answer all your questions and we'll have a fun time. It's probably my most favorite part of the whole show. But that's it. If you have to get out of here, get out of here. I appreciate you coming by on a Tuesday and just hanging out with me for 20 minutes. I do like that, but that's it. So thanks so much for stopping by. I appreciate it. See you on the next one. Let's get into a little Q&A. Darth Mike, what's it showing between friends? I'm still waiting for that t-shirt from Ben. We'll see. Hello, Lexi. Darth Mike, very funny. Let me go up. I think I missed, yeah, I missed all of them. So, ah, Mr. Hogan's channel is called Legal Briefs. All right, everybody can search for that. Again, go to the experts. I'm not the expert on that one. Hogan does a great job, Deaton does a great job to have to check them out. They've got a lot better information than I have. Amy Softball says my best guess is 75 basis points of the market might react stronger to the many countries also raising rates as well. Yeah, the UK just recently did themselves. So afternoon ladies. Hello, Tommy V. Hello, Corey. Hello, Namim. I gotta hold on. There we go. David says, let's get it. Happy Tuesday. Hello, it's from me. Hello, friends. Hey, Rob. Shannon Miller, wrench me. Next time, Shannon. And, ah, well, First Coast Crypto is here. Let's see. Giving some Iowa, Argentina. Well, that's a wide swath of coverage. We'll take it. Whoa, I don't know that. Mr. Wolf says Sweden raised the rate by an entire hundred basis points today. If this happens in the US, the market will go into a complete terminal. Yes, Mr. Wolf is correct. And I'm hoping that actually happens. A hundred basis points would be awesome. Why? Because it would drive everything down. You can get things pretty cheap. Like, I don't really think about it. There's a notification on my phone that happens every day around 7.15 in the morning which says your dollar cost average of these specific cryptos has been executed. One of those is Bitcoin. Another one is Ethereum. Another one is near. Another one is Cardano. There's a couple of those I do too. I know Ben will say you got to take a cold shower because they're going to be lower. Probably right. But I just like the hedge. Ah, Corey says, Rob, you did a CTO last month, great. Isn't CTO such a smart guy? Nice guy. It's so nice to know there's other real estate people out there. There are. He is a good guy. That's why I have him on. Nice. You bring some relevance here. Tom says, I'm thinking 75 basis points. I got to agree with Tom. I think that's the safe bet. But I got to imagine three, four months ago, 75 basis points, everyone was saying 50 for sure. And all of a sudden, after that Jackson Hole conference where Jerome Powell stood up and said Volcker probably five or six times and said, he's going to keep on with doing what he's doing and raise those rates. Everyone was like, ooh, maybe he's real this time. And then people in the bond market are like, he's full of it. He's not going to do it. We'll see. We will see. BlackRock is my landlord. That's the one that concerns me. Is these big enormous institutions are buying up all these houses. And there's a great video by a guy from Coin Bureau talking about you'll own nothing and be happy and what it all comes down to. This is the scary outcome. I think that could be. These big institutions have everything. You rent for a low rate. You don't own absolutely nothing and they keep everything.  Yeah, that's true. Do tall cigars, should I buy Bitcoin today or tomorrow? I can't give tall cigars any advice. I can just tell you what I do, I buy every day. But remember, I buy crypto, but I also sell crypto. And there's a big distinction. I'm trying to get away from that nonsense of, okay, buy, buy, buy, buy, buy and then never talk about selling. There's a video on Saturday I just did which kind of outlines when I sell and why I'm selling and at what points I'm going to sell. But make no mistakes, I am selling. I am not a diamond-hander. I'm not holding forever to give to my grandkids so they can waste it on something. I'm just not gonna do that. I made all the money, they gotta make money. I'll help them out, but come on. And we're gonna go, any sweat cleaners? Well, I'm glad you asked. No, not really, there's not really much going on. The price is going down and sweat going. So that's what it is. I don't know what this is. Ah, here we go. Little background. My builder still has quite a few new builds in the backlog. None of those trains are extremely slow due to lack of workers. Yeah, yeah, that's another thing. The worker pool, you know, it's very hard. I mean, everybody I talked to, it's hard to. And I was talking to a gentleman at my facility and he was talking about how he, he's just a gig economy worker. He drives for Uber. And he says he makes 2000 bucks every week. And this is an El Paso. El Paso. And he said, yeah, I make two grand a week.  And I can go on vacation when I want to. He goes, why would I go back to my old job? I'm not doing that. So yeah, makes sense to me.  Tesla, I don't know about that. I can't even say that one. Darth Mike will probably have more volatility on the last Friday of the month when futures options expire. I always forget about that one. Usually on the last Friday of the month, but at the moment I think there are more shorts. I gotta tell you, a couple of days ago, I think we had over 400 million in shorts liquidated is Doquan hiding in Ian Baleem's shed. That's a good one. I like Ian. I know some people say, ah, he showed me this, he showed me that. Look, you can say that for every social media person that puts themselves out there, including myself. You think I'm guilt-free? How many times did I talk about Bitcoin going 150,000? How many times did I talk about Ethereum going to 10,000? How many times did I talk about Voyager, VGX going to $30 for a token? It's true, I did. But I also said, on investment advice, this is what I'm doing, be careful. And I think people just got away from it. That's really what it comes down to. So, should I have sold more? I should have sold more. Did I sell? I didn't sell more. And that's just the truth. And do I have crypto locked up on Voyager and Celsius? Absolutely, I do. Which, speaking of which, we will be doing a Twitter Spaces, me and Simon Dixon. And the guys from the Celsius squeeze something or other. They're very active on Twitter. And they've been very vocal about they don't like the way that Simon has come in and given different options. And they think that he has his own agenda and he's trying to buy everything on the cheap. So I said, you know what? Let's all get together and talk about it. Because I'm sick of this going around thing. Let's just get everything on the table and say exactly what it is. And then we can move forward and we can get the community behind one specific thing. That's it. I'm getting old, man. And I've only got so much time on this planet. I don't have time to deal with the cheesemate. Give me the facts, then we'd go from there. How's the pure house? That's pretty good. It's a lot better than a lot of other people's. It's not a big E. People's houses are gone. Those roofs are gone. Electricity, I think, is out in a lot of different places. That's why we talked about, for donations, don't give to the Red Cross and the big government agencies because it's so, so slow to trickle down. And we talked about there's some local agencies you can give to, one of those being Protecho's because they're gonna have to build a lot of different roofs out there. And people need a lot of items that can go right now. So watch the video from yesterday, there's a link in there. Get many of them people now. Brian says, too many baby boomers of money. That's got a point. Noel says, crypto must go in more friendly countries. Yeah, I gotta agree. Hello, bullish. Yeah. So Billy Bob says, if there was a catastrophic event, how can we use blockchain to transact? Now, no power, no Bitcoin. You know, there's a couple of different ones that you can use. One of those is Divi. You ever hear of Divi? So Divi just uses a text message service. So if you still have some telecommunications, you could use it in that way. But for Bitcoin, how can you transact? You can't transact. But here's another thing. If you have no power or anything else, how are you gonna transact with your debit card? Or your credit card, where else? That's why when people say cash is king, cash is still king. And if you wanna hide any transactions, I gotta tell you, it's not with credit and debit and crypto, it's cash. Just remember that. So what the heck? Brian says mining is something for now, solar will be a way to go 22 cents a kilowatt hour.  I'm moving to eight cents at a commercial location. Yeah, still too much. That's a lot of money. So there you go. Necessity is the mother of all invention, right? Yeah, Noel says, ETH now is a US product under the SEC. The SEC just asserts that. It's not that there's been any law passed. Remember, the SEC's job is not to make the law. The SEC's job is to enforce the law that has been laid out by lawmakers. There's nothing underneath there that says that ETH is a US product. Doesn't make any sense to me. But that's what the, one of the, the wordings were in the Wells, whatever, to Ian Bolina. The Wells notice. Calm down, Billy. The cash register event would probably mean you don't need nothing of value. Hey, look, I, I was raising a farm myself. We didn't have a lot of electricity either. You know, somebody just don't need it. Be more, be more bearish, would you? Oh, I can try. Look, I'm just a realist.  It's gonna be a while. And, you know, it's just the same thing I did in 2018, 2019. I think some of you were here with me. Well, not here in the channel. Channel started in 2020, I think. So again, if things go down, I'm just, just delicose averaging. Oh, and speaking of which, have you guys seen this website? DCA-CC.com. I wanna see what I'm showing you. DCA-CC.com. It's kind of like DCA-BTC.com, but you can do with the top 100 cryptos and pick a time frame. So like, I'm just gonna show you what I did. So like a hundred, about a hundred bucks a week, right? A hundred bucks a week. That might be super expensive for some people. Some people, it's like, that's nothing. So we'll just go a hundred bucks. Let's see. Let's pick, I started around 2018, January, ah, summer, middle of the month, something like that. And then let's put it today. So a hundred bucks a week, we'll calculate that. And what I like about this is that it'll show you like the average price during this whole time. And it'll see, you see in the bottom right-hand corner it says ROI. Like you gotta understand that you're, you're sucking wind for a long time.  Let me just show you this one. This is the one I like. This was me. Just dollar-cost everything in the Cardano. Down, down, down.  Why are you doing this? I'm like, I think it's gonna do well. And then of course I'm down and down and down. It says a 19, still down. Just plugging away. Now to be honest, there was a couple of weeks when I'm like, man, this isn't work. I'm giving a towel. Then I would come right back because another upgrade, something happening. And I would come back and then it's time went on. So like if I would have sold, I'm pretty good. And that's, so I invested 19,100 and you get 685,000. That's not bad. Am I saying that's gonna happen to everybody? No, I'm just saying that's what's, you know, could be if you sold the top. Here's a hot news flash. I've never sold the top ever. But excuse me. So the website again is dca-cc.com. Interesting. And you can do all the ones. So you can kind of just see it. I like those because it kind of gives you visualization. But there is one thing that is super important in that one. That is that you just see the very top, the 600 or whatever 1,000 it was. But you see after that, how the price went down a ton. It's because you got to make sure that you sell at some point. Don't forget that. Nobody, everyone broke taking profits. Not financial advice. If you want to hold on forever, it's fine. That's a great question, man. When sold the power in Puerto Rico? When I get down there, maybe we should talk about that and putting our efforts into doing those types of things. It is. One butter knife. That's a different time. Let's see, where do we go? Oh, so Rao, I don't mean to be off topic. Didn't she recently buy a home in Puerto Rico? Yeah. Do you know how your home is doing? Yes. We have property managers that deal with it. The same thing is okay. Problem with the shower nozzle or something, but not too bad. Let's see. Buy the, EOS is going to the moon, to the moon. I don't maybe, you know, Beardy would like to hear that. Hello? Oh, this other one, Zed Zed. There's a Bitcoin minor satellite in space. Just connect to the satellite, the Transact and Bitcoin.  I'm like, I've been on this planet almost 50 years. I've never gone through those. So I don't know what to tell you. Cryptometrics, I hope XRP goes to zero. I don't. I still have some XRP. Nick says, Robby DC, I'm in tomorrow. Nick, this was a great, because what I used to do, and it worked out pretty well for the most part, is I would wait until the announcement and then I would just see what Jerome Powell said. If it was in line with what people thought and the markets rallied, then I would buy immediately and then I would just wait for the things to go up. But then I would also, if it went the opposite way, like last time I think it was, and it was so aggressive, I would just wait and then wait for the market to drop. And I would take a point and go, oh, that sounds pretty good. It's going there. Worked out great last two or three times, but this one, I didn't get into it. I had a lot of things going on, so I just let things go. I will, no, not may, I will. If Jerome comes out and says a hundred basis points and things just tank, I will do what's called dynamic DC-ang and buy a little bit more so I can cash out more later. JH says, Rob, you've inspired me to start a YouTube channel, fantastic. I just got into crypto to hide the bull run and I'm almost, I'm down almost my entire portfolio. Sounds exactly like me.  Captain obvious, Rob, very funny. That's a good one, David. We are due for many bull rally tomorrow, perhaps? Ah, that's a good question. But if we do, I might be selling some. A little bull rally would be nice, especially as we've hung around 18K. And yeah, black rock is everyone's lord, that's the truth. Money is the greatest disadvantage. John says, Rob, wouldn't it make sense for sellers to give us our crypto back when the market tanks? Imagine Bitcoin at 9,000, it'd be cheaper to give it back. Depends on where the funds are coming from. I mean, where is their, my question is where is their liquidity? As I was taking a look at the financials, not too long ago, they were supposed to run the money in October and all of a sudden money magically appeared and they have operating expenses all the way till 2023. And that's just the operating expenses. The question that I have is, first of all, where'd all the crypto go? That'd be interesting. And the second of all is cash on hand. What do you have and how much do you have available to fill that hole? Cause the hole is over a billion dollars. So that's a good question. CTO Larsen needs wrenches, he does. Pioneer, better trade than Ether. I don't know, maybe. Celcius short squeeze. You know, I just don't understand the short squeeze. I can understand the initial parts of it where people really like, we want to punish the people that punish Celcius. Okay. But then as we've dragged this on, like now who are we punishing? You know, and who is it all for? And from the things that I've seen, I mean, who are the heavy Celcius holders who are cashing out? They're the ones that are making the money. Just something to think about, that's all. Mm-hmm. Yeah, Tika says, what do you think about a sweat staking 12%? That's a pretty high. I don't know. I was just, to me, I don't know. I mean, it sounds pretty good, but if it's too good to be true. Yeah, I don't know. The question I have, I don't even, I don't know this. Maybe you guys can help me is what the lockup period is. Go from there. 12% is pretty damn high. I was just surprised that near protocol was able to handle the transaction speed or all the transactions for sweat coin. You know, sweat coin is 80% of their whole transactions on chain. 80%. Diamond hands never sell. Yeah, look at that. 1,000 people watching today. It's always good. Ben just says, you can still go broke taking at profits if you spend it all. Well, that's true. I can't help you after that. Ah, Robin engineer, I'd be happy to help you look for alternatives. Sounds good. Always find me on Twitter.  Damn Twitter is annoying. Annoyingly addictive. Another thing, if anybody has any insider information on how to get that blue check mark, I'd really like to talk to you because I've tried five times now and they keep denying me. They've done that in me, then I've been and I was the other guy. I forgot. I think that's it. Wow, 12% is 12 months. I guess they for a full year. That's a long time. Holy smokes. That's right. Damn it, I keep hitting the wrong button. Do you think it's stuck on 617? Yeah, I would draw it out after that for sure. No. So Corey says, Rob, do you use a traditional bank for your home loans? So we bought cash for the houses and because these reporter recon properties and to get a loan over there is like an act of God. So that's what it came down to. And then if anybody's curious, as far as how much you can get for each crypto if you stake them and the lockups and all the data, there's a great website called stakingrewards.com. And you can just scroll through here and just see what the average rewards are. You know, Solani gets 6%. It's pretty good. Ethereum 5%, but he got to deal with the slashing and the lockups and whatever that happens. Avalanche is 8%. Polkadot is 14%. Cosmos, 18%. What? Sweet Mary and Christmas. That's huge. 10% for polygon? Oh yeah. ICP 8%, 8% for flow.  EOS is 33%. Oh, what? That's what it says. Anyhow, Algoround 8%. So if you're, you know, just look at the actually infinity is 61%, that's insane. If you're looking for something like that, I can't give you advice for which ones to do. I would definitely take a look at the lockup periods at any kind of like penalties and go from there. That's, that's insane. And if it's too good to be true, well, it usually is. Oh yeah. And then meld 12%. I've locked mine up though, a while ago. Did not know that. You see that Gemini now is a staking option for medic. Not just there. Very nice. I thought Gemini would never do that. Yeah, no kidding. Dump. I need to stake it. Oh yeah, it's locked up in Voyager. Womp, womp. How many shares do you have in Twitter? I have not as, not enough. Holy smokes. Bitcoin's at 18.7? Thanks. I'll speak to some people already. Thank you. And that's it, everybody. OK. So today's going to be a really, today. Next two weeks are going to be kind of odd, so stick with me because we do this charity course for kids here in El Paso, off to the course. And I do, I work with the guys to do the construction and the marketing and getting things together. So usually I work out there in like the morning, like six in the morning until it gets too hot. And I come into the video and sometimes it gets pushed out. So just be a little patient with me. So don't expect these to be on the same time every day for the next two weeks. That's it. So look, everybody, thanks for stopping by. I do appreciate, like today's video, thumbs up, subscribe, all that good stuff. But that is it for today. Thanks for stopping by. That's it for today. So thank you. I'll see you in the next one. Adios. Do, do, do, do, do, do, do, do.


Welcome to Comparing Electronic and Hydraulic Components. In this video, you'll learn about the similarities of electronic and hydraulic components and be able to pair schematic symbols through the review of examples. The operation of an electronic circuit is similar to that of a hydraulic circuit. The components are also very similar. Take a moment to review the schematic symbols for the electronic and hydraulic components in each column. The symbols in each column represent the electronic and hydraulic components that are similar in function. Now, follow along as we review the similar functions of the electronic and hydraulic components in each column. The reservoir is a common point in the hydraulic circuit where fluid begins to flow and where it leaves a hydraulic system. The ground is a common point where current begins to flow through the electronic circuit and where it returns after going through the circuit. The pump causes fluid to flow through a hydraulic system. The power supply causes current to flow through an electronic circuit. The pressure gauge measures the pressure at a given location in a hydraulic circuit. The voltmeter measures electrical pressure at a given point in an electronic circuit. The flow meter measures how much hydraulic fluid flows through the pipe to which it is connected. The ammeter measures how much current flows through the wire to which it is connected. The pressure relief valve maintains the constant pressure at the circuit location to which it is connected. The voltage regulator maintains a constant electrical pressure, or voltage, at the circuit location to which it is connected. The directional valve opens or closes the hydraulic circuit to enable fluid to flow or to stop it. The switch opens or closes the electrical circuit to either enable current to flow or to stop it from flowing. The accumulator begins to store fluid when the pressure increases and discharges the fluid to maintain flow when the system pressure decreases. The capacitor begins to store electrons when the voltage pressure increases and discharges electrons when the voltage pressure decreases. The variable flow control valve is a restriction that can change the amount of fluid flow that occurs in the hydraulic system. The variable resistor, or rheostat, is a restrictor that can change the amount of current flow that occurs in the electronic circuit. The check valve allows fluid to flow through it in one direction and blocks the fluid flow in the opposite direction. The diode allows current to flow through it in one direction and blocks the current flow in the opposite direction. As fluid flows through the hydraulic motor, it converts hydraulic energy into mechanical energy. As current flows through the electrical motor, it converts electrical power into mechanical energy. The fluid exits the hydraulic system and re-enters through the reservoir. The current exits the circuit and re-enters through the ground. Now try to match the electronic component at the top with the hydraulic component at the bottom that performs a similar function. If you get stuck, you can go through the video again to review the pairings. You have completed the video comparing electronic and hydraulic components. Thanks for watching. If you liked the video, give us a thumbs up.


Hi everyone, it's 4pm here in Edinburgh. I'm in the middle of a heatwave so it's 23 degrees outside at the moment. Apologise if I melt during this call. I'm going to share my screen. So it's time for the update on what the discussion team has been doing for the last five weeks. 9.3 is going to be released later this week. Some of the features that we've been working on in there, the conversational development index. This is a feature available to GitLab instance administrators. So gitlab.com users won't really see much of this but people who run their own GitLab instances will see it. And it's a way of showing people how their usage of GitLab compares to other uses of GitLab. So if you have the usage being enabled, you send data to us and we provide this back. Not in exchange but we provide this back. So it shows you, for instance, if you're using GitLab CI, more or less than other related people. And Adam's been working on that. It looks really nice. So the developers continue to add nice stuff to snippets. So now snippets can have descriptions as well as code, which is awesome. That's in addition to having comments as of 9.2. As well there's been working on something that's user facing but not like noticeable to users in the sense that they won't see anything in the UI. It's a feature that lets us restrict certain features to name spaces on gitlab.com, which means that we can let people buy into e-features on gitlab.com. And Jak has been working as well on improving the JIRA integration settings. So if you have your JIRA host split by web and API, maybe different ports, maybe different host names, you can configure that again. Valerie's also worked on a really cool elastic search improvement, which is that now if you search for part of a camel case name, it will show you that in the code search. Previously it would only show you if it was prefix. So in the example there, I don't know if you can see the screenshot very well. But he searched for files and archive, from expected files and archive. Previously it would work if you searched for expected files, but it wouldn't work for files and archives. So that's really nice for people using camel case languages where camel case variable names are common. And this is a community contribution that Adam helped review along with Annabelle in the blame view, which we now call the annotate view, but hopefully you know what I mean. We have a little key that shows how old a line is. So you can see in the screenshot that the oldest lines are sort of have the fainter color in that sidebar, and the newest lines have the darker color. So that's a really cool feature. I was going to have some stuff about performance improvements here, but we are still the measurements. We only deployed most of the 9.3 features today. And I've noticed for one of them we still need to add an index to make that improvement work the way it should. And for other ones we're seeing, you know, the database has been hammered pretty hard today. So I'll try and get some charts added to this presentation later on. Things that didn't go so well in 9.3 or in general, relations between issues slipped again. It slipped from 9.2, which wasn't a huge problem. That it slipped from 9.3 is not so great. I don't really want to go into too much detail here because there is a huge amount of text. First of all, there's a retrospective for related issues itself. And second of all, there's a bunch of stuff about related issues in the general retrospective document we have from 9.3. So I'll let people read those and have their comments there if they want to. We also need to make merging merge requests more reliable. Basically if, for whatever reason, we can't update the lock status. When you try and merge a merge request, it goes into a locked status. If we can't update that, when we attempt to merge it, after attempting to merge it, so that it's unlocked, we make people wait 24 hours, which is a really long time, and it's a really bad experience. It's just really, really annoying. So I hope to get to that in 9.5. And we still haven't done the public API for merge request diff discussions. That's partly because we're working on adding those discussions, resolvable discussions to issues as well. So we'll do it all at once, but it's kind of annoying to me because it's obviously the biggest gap in our current REST API. In 9.4, and beyond that, we've got a bunch of exciting stuff. So we've got native group milestones. At the moment we have a thing called group milestones, but all we do is group milestones within the group, projects within the group that have the same title. But this is real group milestones congruent to group issues and, sorry, group labels. And once we do that, group issue boards will be able to use those group milestones and group labels, and we'll be able to build group issue boards. Janine has also been working on a declarative policy framework, which is a new DSL, the main specific language for our developers to use when they're assessing permissions or policies. It makes it easier to extend for E, and it also makes it easier to do things. So we normally have a couple of different permission checks we do. We say, for instance, can this user do this action on this thing? Or we might say, which users can do this action on this thing? Or we might say, what actions can they use to do on this thing? So we've duplicated logic in some places to make some of those faster, but this framework makes it easier to just declare that you want that and let the runner, the framework, the policy runner, handle that for you so that you don't have to duplicate the logic in a couple of places, which hopefully means fewer bugs and we keep the same good performance. Valerie is working on a Slack app for GitLab.com. The reason it's restricted to GitLab.com at the moment is that as it stands, Slack apps can't be configured easily to set a different endpoint. So when you authenticate with a Slack app, you have to authenticate with a known endpoint, which in this case will be GitLab.com. But we're hopeful that that'll be possible in future. So the work that's being done on this might be available to people using self-hosted GitLab in future or just non-gitlab.com. Also, might not make it into my.fi, but I mentioned this last time, integrating into the Jira development panel, there's a community proxy, which is written in Java that allows this at the moment, and we will probably take the same approach initially, which is Mimic GitHub Enterprises API and OAuthflow. And if people configure GitHub Enterprise with the instructions we give them in Jira, they will get their GitLab instance, which will let them see commits, merge requests, pipelines, and so on in Jira, which is really awesome. As an ex-Jira user, I would have loved that. One of the slowest things about loading a merge request is if we have a merge request that has a lot of commits initially, and then we add commits to it. So say we have a merge request that initially contains 200 commits, and we add 70 commits to that one by one. We get the pipelines for the merge request, and the way the commits are stored for the merge request is in YAML, which means that we can spend 60% of the time during that page load, just deserializing that YAML. That's not querying it or fetching it from the database. That's just taking the YAML we've got from the database, figuring out what the objects are, and then going back and asking the database for things belonging to those commits. So making this a real table is tricky, and the migration will be tricky as well, but hopefully it will improve load time quite a lot on large merge requests, because at the moment, if you have a large merge request and you add to it, it gets slower as you go, which is, again, a really bad experience. And finally, released issues will be there. It's in master. It's definitely going to be in 9.4. So I definitely won't be talking about that next time. I'm going to stop sharing my screen now to see if anybody's got any questions. Rebs asked if snippets can be versions soon. So, yeah, one thing that would be awesome is if our snippets were Git repositories, like GitHub Gists. I don't think we have any plans to do that at the moment, but it would let us do things like have multiple files in the snippet, or, like you said, versions of snippets. But I think the improvements you have just made, we'll see if we can get on to that sooner. I'll give everybody 10 seconds for other questions. Otherwise, go enjoy the sunshine, at least if you're in Europe. Okay, great. Have a great day, everybody.
