O.C. 16, Hawaii's weekly newscast on things that matter to tech and to Hawaii. I'm Elise Anderson. And I'm Helen Dora-Heiden. In our show this time, we'll take a look at some of our most recent video commentaries. In its efforts to raise public awareness, ThinkTech encourages its hosts to express their views. And we wanted to give you a sampling of what they've had to say. ThinkTech produces some 30 talk shows every week in our downtown studio. In addition, we record, produce and accept commentaries on public issues, and we want to bring them to you. So for this show, we've chosen five popular commentaries plus a staff pick to share with you. These commentaries are as follows. Commentary number one, a commentary on Trump-Loy on ThinkTech regarding distractions from the White House. This is Trump-Loy on ThinkTech, connecting the dots on what our president is doing and how it compares with what has gone before and what it portends for the future. It's not a pretty picture. It's no joke that Donald Trump is at the center of the first dozen headlines on any given day. After all, he works at it and cares deeply about himself and his ratings. Shades again of the apprentice. Some of these headlines seem to be make work, not only to bring attention to himself but to distract us from the other things he is doing. What he is doing with the hand behind his back, which he really doesn't want us to know about. It's the height of demagoguery and he's good at it. This week, he resumed his attack on Hillary Clinton, continuing the election drama, however inconsequential at this point. Could he be hiding something, trying to throw us off? The press seizes on all his zigzag bait. But what about focusing on the matters of real concern about the matters that really affect our country and our future? And this week, he quote, declared opioids a public health emergency. When did he become aware of that? At a time when he is regularly victimizing immigrants, minorities and the press, encouraging nuclear proliferation, ignoring flood victims and undermining health coverage for millions, do you really think he cares about opioids? Rather, he is camouflaging what he's doing to rip off the middle class with a huge tax break for the rich and to move the hot light away from the central threat he faces, the investigation of how he collaborated with Russia to manipulate the vote. And reason indictments over that. He's brilliant at changing the subject and feeding the press with a showman's parade of lies and irrelevancies. That said, now we can surely expect new distractions. Simply stated, as Americans, our job and civic obligation is to be informed and not to be misled, to separate the wheat from the chaff, to know when he is distracting us, and to find out what he is distracting us from and why, and to focus on the reality rather than the smoke screen. Anyway, thanks for watching Trump Loy. We'll be back with more as the Trump administration further unfolds and unravels going forward. Commentary number two. A commentary by Craig Wagner on resistance to immunizing the children in our community. I'm Craig Wagner, and I want to talk to you a bit about immunizing your cakey. Should you do it? Well, in a word, yes. Now this doesn't seem like it should be a real issue or question anymore, a no-brainer, right? I mean, should I drink half my weight in beer? No. Should I wear a thong bathing suit to the beach? No. Should I expose my child to life-threatening illnesses that are completely preventable? No. But it still is an issue. And despite the fact that the primary reasons proffered by anti-vaccinators and disproven time and again, people are still telling their pediatricians in schools that they don't want to vaccinate their children. Now look, for many of you, this is not an issue because over 90% of the population has been vaccinated for most of the primary diseases for which vaccinations are available. Those include polio, DDP, diphtheria, tetanus and pertussis, chickenpox, and MMR, measles, mumps, and rubella. That still leaves a large number of people that are not vaccinated, increasing the likelihood of an outbreak of serious illness. In fact, we're seeing an outbreak of mumps in Hawaii right now. You know who's not contracting mumps? That's right, the people who are immunized. We do so many things for our children that it seems almost unfathomable that someone would intentionally refuse to have their child protected from these preventable diseases. Those that do are adamant to the point of being combative about their position. And they must have strong reasons for doing this. So let's look at the top three reasons anti-vaccinators cite for refusing to inoculate their kids. And we'll start with the biggest one first. The first reason is, I heard it causes autism. This is absolutely false. Well, okay, not absolutely. You did hear that. It was said by someone and passed around for a while as fact. That someone was Andrew Wakefield. He published a study many years back claiming a leak between the MMR vaccine and autism. The problem was it was only based on a sampling of eight kids who follow any of the methodology or protocols generally required for anyone to even consider it science. But it was picked up and put in a medical journal at that time. And that gave it the air of fact. Since that time Andrew Wakefield's study was completely debunked and disproven by numerous other studies on large segments of the population. Those studies time and time again demonstrated that there is absolutely no link between the MMR vaccine and autism. And if you're wondering why I'm not referring to him as Dr. Wakefield, well that's because as a result of his pseudoscience and the debacle that followed, the medical journal that printed his article was forced to print a retraction. And Andrew Wakefield was stripped of his medical license. Yet the damage was done because nowadays people citing autism as a reason for refusing the MMR vaccine for their kids just say, I heard it caused autism with no idea where it came from or whether there's any real science behind that statement. And I've heard something really should not be a reason for doing or not doing anything. At least not something as important as immunizing your kids. Now the second reason that we often hear is it's just a money-making propaganda for doctors in big pharmaceutical companies. Okay, here's why I have to give a bit of a disclaimer. My wife is a pediatrician. Oh and my father is a doctor and so is my sister and her husband. I'm not a doctor, although at this point I'd certainly be willing to play one on TV. What I can tell you is that these kind of vaccinations for kids are no money-maker, which is why my wife's still driving her 10-year-old minivan with a dent inside. And don't get me wrong, pharmaceuticals make a lot of money, absurd amounts of money. But they primarily get that from selling drugs that make things hard or soft. The MMR vaccine and others like it are not money-makers and actually cause pediatricians more than they're able to get reimbursed by insurance. Given the choice, doctors and pharmaceutical companies would concentrate on other things and drop these vaccinations in a heartbeat. The last reason that people cite is that famous people have said that the MMR vaccine causes autism. This is by far the stupidest reason I've ever heard from refusing to vaccinate your child. But people like Jenny McCarthy and Jim Carrey have been publicly trying to persuade people that these vaccinations are bad and may cause autism. Now as an initial matter, I don't think you should ever take medical advice from a guy who started dumb and dumber. But more importantly, these people haven't added anything to the debate other than repeating false signs and being famous. I mean for goodness sakes, Donald Trump has taken a stand as an anti-vaccinator and if that isn't a reason for getting your kid to the pediatrician and getting them vaccinated, I don't know what is. Now look, and I'm talking to those of you on the fence or to consider yourself anti-vaccination.  You have the right and responsibility to be on the lookout and to look into everything. But the MMR vaccine and other standard vaccinations are not one of those dangerous things. In this day and age, the reason the leading causes of death in America are things like heart disease, cancer, and accidents is that we are not having mass epidemics of disease that wipe out thousands and even millions of people. And the reason for that is vaccines. So do the right thing. Don't use your child's health as a testing ground for propaganda and your right to take a stand.  Hey, thanks for watching. I'm Craig White. Commentary number three, a commentary by our host, Seymour Kazimurski, in which he gives us some new year's advice for 2018. To all my family and friends around the world, it's time to say aloha, au revoir, au videsaigne, sayonara, arrivederci, d'os vedaniya, jayan, to 2017. With what we've seen of weather disasters, economic problems, and difficulties in our cities, there are likely many of us who would say good riddance to 2017. But let's not forget some of the good news, such as the encouraging stirrings and revolutions for democracy that we're seeing in some countries. There are also studies indicating that violence is generally decreasing in tangible ways. And in the debates and protests around the globe, I have been struck by the tremendous heart evident in people. In light of such things, along with what hopes we still have within us, maybe we can begin to see in this past year something of the promise of good that's already here. Sure, hope isn't enough to help someone recover after a disaster, but let's consider where things can go when we see our lives from the standpoint that we control our own destiny and we can discover the true meaning and purpose of our lives. This year has had its challenges for me, including my personal health challenges, but it then recently occurred to me that I was overly swayed by the bad news going on and not swayed enough by the promise of what I was able to discover in all the good around me. This realization was a powerful turning point for me, from which I went forward and found ways to make a difference in my year, and I would like to think in the lives of those around me. It's in this spirit that I've thought of the past year as really having been full of promise, a positive view of things makes all the different. It's this lens that enables us to stay above the fray, harvest the good of the present, and so best prepare for tomorrow. Are we waiting for good to come along from somewhere else? Are we focused on ways we haven't seen the good we want? Or rather, are we trying to see more of the good that is already around us? Truly, the good that's in store for us is not something that's yet to be created. It's ready for us to see, take hold of, and do what is best for ourselves and others around us. We're learning about what works in life, and maybe plenty about what doesn't work, and there's enough going on to suggest that we'll continue to gain in our role as good people doing the right thing to make our world a better place. So my friends, I look forward to your great anticipation to 2018. For me, a year of promise. For you, and for the world, because the beginning starts with you and with me. Looking forward to hearing from you, please be safe, and may God bless you with good health and the spirit of giving. Aloha and Happy New Year from the Kazimerskis and Seymour's World. Commentary number four, Commentary by our host, Kilii Akina, on the pilot project for rideshares by Uber and others at the airport. I'm Kilii Akina, and although I'm a trustee of the Office of Hawaiian Affairs and the President of the Grassroot Institute, the comments I make to you today are in my private capacity, and do not necessarily reflect the views of any institution. Hawaii took the long route to increasing consumer choice at the airport, but finally we've arrived there, or at least we're getting there. After a lengthy negotiation, Uber and Lyft permission to pick up passengers from two designated areas at Inouye International Airport. Now, for travelers frustrated by long lines and lack of options, the absence of the two popular ridesharing companies was very confusing. Why limit a transportation option at a major vacation destination when other airports are doing it all the time? Well, the answer comes down to regulation. Because taxi companies in Hawaii are heavily regulated, they protested, and probably rightly so, the fact that Uber and Lyft were not forced to compete on the same playing field. The best solution from a free market perspective would be to reexamine and ease the regulatory burden on cab companies as well. But the state went a different route, often spread red tape around a bit more. So like taxi drivers, Uber and Lyft drivers will have to pay for the privilege of picking up airport passengers. The pilot program requires the rideshare drivers to pay 7% of each fare to the Department of Transportation at the airport's division. But rideshare drivers are still not allowed to solicit customers, and they cannot wait at the airport. They're limited to prearranged pickups only. Uber estimates that a ride from the airport to downtown will cost about $17 to Waikiki about $24, and to Kapolei it will run about $36. Well, more competition does mean that customers should benefit from shorter waits at the airport. And while this is a trial program for now, if things go well, the temporary three-month permit could become permanent. It's at least an important first step toward increasing consumer choice, along with creating new jobs and opportunities in Hawaii. However, we shouldn't forget the fact that the state regulations load availability of ridesharing in the first place. And the reality is this, if Hawaii wants to remain economically competitive, we should be looking for ways to decrease state involvement in the market, both for cabs and other rideshare vehicles, and not weigh everyone down equally. But that's probably good enough for now. Commentary number five, a commentary by our host Marcia Joyner on the recent mental health escapee and what she feels is wrong with our state health department. What is wrong with the health department? How is it they allow a young man who's been locked up for 30, 40 years at the state mental hospital to leave to walk away to get a cab, to get a charter plane to take him to Maui, and from Maui to California. Every time I go on the plane, I have to have a picture ID, I have to have a credit card and a passport. And then they go through all your bags and they do all of this stuff. How did he get that when he's been in the hospital for 40 years? How did all that happen? The only way that happens when he walked away from the hospital, he didn't have all that and somewhere along the line and can you pick up the phone and call and say I want a charter plane, meet me at the airport? How does that work? And now the health department is telling us they can't talk about it. The health department has messed up this whole thing with cannabis, medical cannabis.  They didn't tell us about it until it was well out of hand. We still don't know what's going on with the mumps. They have dropped the ball. They did not pass. The health department did not pass on their inspection of nursing homes. We passed the legislation for cannabis in year 2002 and they still haven't gotten the dispensaries and things up. What is wrong with the health department? If you're going to vote and you must, or governor, you tell whoever is running for governor that they have to get a handle on the health department. And our staff pick a commentary by concerned citizen Sarah Fairchild on how homeowners can inadvertently lose the benefit of the homeowner exemption. If you are a Honolulu County homeowner who lives in your home the majority of the year, it's time to file for the homeowner's exemption on the city and county website realpropertyhonolulu.com before the September 30th deadline. This is particularly important if you are a first-time owner or an owner who has recently moved back into your home. It doesn't hurt to fill it out again if you're not sure if you have it. This is how the home exemption works. The basic home exemption of $80,000 is deducted from the government's assessed value of the property and the homeowner is taxed on the lower value remaining. The property must be classified as residential to get the home exemption. When the homeowner does not live on the property because it is a rental property or a second home, the wording changes subtly to residential A. There is then no $80,000 exemption and the property is taxed at a higher rate. The application process for the exemption on realpropertyhonolulu.com amounts to little more than checking some boxes. However, if those boxes are not checked by the time the clock strikes midnight on September 30th, your property bill grows substantially. The city does notify you by a line item on your tax appraisal statement of your exemption status and is supposed to send you a letter if your status changes. However, for the average person not trained in real estate or tax code, it is easy to miss this change which can cost you thousands of dollars. Many people who pay property taxes through their mortgage companies do not even discover an error until several months later when the lender sends them a bill to close shortage. If you do not file the exemption by the September 30th deadline, it is almost impossible to get the exemption retroactively even if you can prove with evidence that you are living on your property. This is a major flaw of the city and county ordinance that needs to be changed. If you make a mistake in filing taxes, you should have to pay a fine perhaps, but not be subject to paying thousands of dollars extra in taxes as though the error is the reality.

To research what you buy if you're doing digikey every single week lady user powered of engineering to find The most precious things in the world right now electronic parts Okay, so we're gonna go to digikey.com and try to find something this week. What are we gonna try to find?  It's a story about a part of care find So the I've actually you know a while about a year a year ago I ordered, you know a year's worth of components from ST sensors, you know, I've been ordering a year's worth at a time usually instead of a quarter quarter's worth because it's been so tough to get parts and Some parts from ST I've been able to get like I got LSM 60 socks is and I got some you know ISM 330s But what happened is I often what I've liked to do is I like to make a combo IMU where I take You know a accelerometer gyro I stick it with a magnetometer because it's actually not that usual to get a nine-doff in one usually don't get all Accelerometer gyro magnetometer in one package. There's the LSM 90s one But like really good luck getting that one. You're it's basically you're never to find it It's pretty common to have them as separate chips and then you you fuse the the data together and you get You know XYZ orientation. It's cool And you know, like I said earlier, you're not gonna get B&O 0 5 5 or 0 8 5 like any time soon Those are those are totally unobtainium So I got the accelerometer gyroscopes. What's interesting is I've totally not been able to get magnetometers I did get some list 2 MDLs, but not the list 3 MDL and the list 2 MDL is a plus minus 50 gals and the list 3 MDL is a plus or minus, you know 16 gals which is the same as 1.6 mila tesla so divide by 10 to get from gals to mila tesla And this is better because you want you want something that has you know good 16-bit resolution and Accuracy because the earth's magnetic field is much lighter than you know Magnet that you have in your hand and there's mainly two kind of magnetometers There's like the high-range magnetometers that are good for detecting magnets And then there's the low-range sensitive magnetometers that are good for sensing the earth's magnetic field So the the list 2 MDL is not a it's not a bad magnetometer for that But I'm also a little worried. I won't be able to get that chip as well other magnetometers I have I either haven't been able to get or they are the high-range types So what I'm you know, and then I'm not sure I'm ever going to get the 3 MDLs again I do have a you know big order in With ST, but it's just this you know, I think everyone's just totally crunched with this part shortage so what I'm going to do on this great search is I'm going to find a high-resolution select 12 16 18 20 bit Triple axis magnetometer that's I squared C because I want it to work, you know, I want it to be compatible not maybe not pin compatible, but it is as functionally compatible as possible so I can pair it You see here. I have the the chip next to the IMU for a 9 doff sensor, so let's go to dig a key and And let's search for so this is the part I'm looking for the list 3 MDL So let's just go there because it's always good to you know You start with the part you can't get and sometimes it's it gives you ideas of how to find the part you can't get So this is the part that you know if you put in that you want some it says, you know, I don't know 2059 I don't think it's actually 2059. I think what they're just saying is we don't know when we're going to get the ability to make this I think you need a particular kind of Fabrication technology which is superbooked So what we do wants let's go down here, and then we can use this to search so you want a magneto resistive active XYZ Xcelometer that's sorry magnetometer that's surface mount You know, I don't really I don't I'm not going to specify the range because I don't care if there's multiple ranges or one range The voltage supply I'm not worried about it's probably gonna be three volts Resolution I don't want to be too picky Package I don't expect to get the same package, but I do want it to be you know the minimum is it's a it's a magneto resistive active XYZ, so let's search Also, I want to be about the same cost the 3mdl is you know, basically one or two bucks So I want it to be about that price. I don't want to spend Like $20 on this part Okay, so output type So this is the thing that I'm going to select first because there's not a ton of options here Which is good actually there's only 10 That's very small So I think I want I squared C and SPI only So let's let's do that limitation all these ranges are quite good Remember the list 3mdl is 1.6 mila Tesla I don't want it to be much bigger than that because I want it to be again used for Earth Sensing so I don't want it more than like five, but all these are are quite good All these cover 3.3 volts, which is what's important to me You know, it's if it's lower great, but that's all I care about all them have 16 plus resolution So it's really good. So let's see what's available So there is the the ST ones. They're not in stock I think let's let's look at only ones that are in stock right now Okay, looks good. So we have a couple options here actually And they all look they all look pretty good to be honest. So there is From you know mem sick, there's a couple options from Rome There is an option with a lot of pieces But what I really liked is you know when I was like, okay Well, I'm probably gonna buy, you know 3000 of these because I'm gonna use it a lot of stuff When I looked at the price The price of these mem sick ones was like very very attractive and I know mem sick makes, you know, good components, too So this could be a good alternative. What I'll do is I'll probably make new Versions of all those IMU plus magnetometer breakouts and then when I can't get the list 3MDL You know, because there's people who have those the code already in their design We can always go back But as long as I have a lot, you know libraries for all them I think people can can switch pretty easily in case it's another year or two So there's two options here, but they'll look really good You're probably wondering, well, what's the difference between, you know, the MMC 5603 and the MMC 5633 They're both very similar Let's look at the MMC because I did Pull up these data sheets and I do this little trick where I kind of like Scroll down and I try to like I Try to get like the data sheets to kind of like be almost the same And then I kind of flip between them to see if I can see what's different and If you look down here, what's different What's different is on this one you see there's a This one has a I3C interface in addition to an I squared C interface So that's basically what you're gonna pay a little bit more for on the 5, 6, 3, 3 They're both actually pin compatible They are not completely code compatible. The register map is a little bit different But they are, you know, this is unfortunately it is it's a BGA. It's a WLCSP With 0.4 millimeter pitch, but if it only has four pins, I'm not as nervous about it I don't have to do a fan out like, you know, four pins mean that I can just I can just bring the pins out from each corner when something has Nine pins, you know, there's always a pin in the middle and that can be tough to get out But with four pins, even if it's fine pitch, I'm not I'm not as nervous about it So this one is a really good option. So I think I'm going to start and also I really like that There's 77,000 stock I'm probably going to start with, you know, making a systemic UT breakout for this MMC 56.03 so you can get Arduino and circuit Python and Python library code going for it and then You know, if that's good, I'll you know Just like connect it up with an IMU and like stack them one on top of each other and then like try twisting and turning it with our Fusion code and just make sure that it like works fine with that and if it does I'll make new breakouts and just, you know, tell folks like hey If you're waiting for this 9-dolph that has the list 3MDL and you don't want to wait Because the magnetometer is not an important part of an IMU like you want a good one But it's not it's not the thing that really affects the quality of an IMU the thing that really affects it is the gyro That's what's important. And so Matching, you know, the as long as the gyro is good as long as you match with anything That's a kind of reasonable magnetometer. You're gonna get good data. So This one looks good If you're if you're in the in the market for a magnetometer and you can't get one because you can't get one this one's cheap and available and You know, it's not hand solderable But it should be pretty easy to work into your pick-and-place manufacturing setup. That's great church


Kun luokasimme sähköisellä analysiit, voimme aina alkaa poittia, tai joudun koko ajan suurin, koko ajan suurin tai koko ajan. Sitten pitäisi tulla, miten järjestämme sähköisellä ja se on kenttävä kenttävä kenttävä. Se kenttävä kenttävä kenttävä ja käytämme sähköisellä ja sähköisellä kenttävä ja kenttävä kenttävä joka on kenttävä. Nyt esimerkiksi, Stannadero on hirveä, tai kalkkulajan Stannadero on jotain, joka on tarpeeksi, että me ei olemme voineet tehdä, tai asumme, joilla me tiedämme, että ne eivät ole todellisia perustamme dataa ja analysoidaan. Bootstrappingi on tullut uudestaan kalkkulajan Stannaderoa, tai esim. kuinka paljon, että statistiikki tarvitaan yksi samppalista. Bootstrappingi on täysin komputationaalinen approaches to the problem of calculating a Stannadero. How bootstrapping works is that we have our original sample. So we have a sample of 10 observations here from a normally distributed population with mean of zero and standard deviation of one. So that's our original sample here. The mean is 0.13 from that sample. And if we take multiple samples from the same population, here is the sampling distribution of the sample mean if the sample size is 10 from this population. Most of the time we get values close to the zero, which is the population value of mean. And then we have some, sometimes we get estimates that are far from the actual population value. The idea of bootstrapping is that if we don't know how we estimate this the width of this sampling distribution or the shape using statistical theory or a closed form equation, then we can do that empirically. So instead of calculating it using an equation, we take repeated samples from our original sample. So that's our original sample. It forms the population for the bootstrap. Then we take a repeated sample. So we take first 0.31, it is here. Then we put it back. So we allow every observation to be included in the sample multiple times. Then we take randomly another one 0.83, it's here. We put it back. Then we take yet another number, yet another number. We take the minus 0.84, the second time and so on. So we take these samples from our original data. And every observation can be included in the sample multiple times. So each of these randomly chosen numbers doesn't depend on any other previous choices. So we get using this bootstrap sample, we get 0.34 as sample mean. We calculate many, many times, typically we do 100, 500 or 1000 times or even 10,000 times depending on the complexity of the calculates. 1000 repetitions is quite normal nowadays. So we can see that from sample to sample this sample mean varies and this variance of sample mean, calculator, the distribution of this sample mean from the bootstrap samples, calculated from 1000 bootstrap replications here is about the same shape as that if we would take the samples from the actual populace. So these two distributions are quite similar and we can use that information, the knowledge that these two distributions are similar. They approach each other when the sample size increases. We can use that knowledge to say that this distribution here is a good representation of that distribution and if we want to estimate the standard deviation of this distribution which is what standard error quantifies or estimates then we can just use the standard deviation of that distribution. Here we can see that the mean of this distribution is slightly off. That's called the bootstrap bias. So this mean here is roughly at the mean here. So it's not that the populace mean instead of it's closer to the mean of this particular sample. Then we also the width of this distribution is in this case slightly smaller. So the dispersion here is slightly smaller than the dispersion here and that is also something that we sometimes need to take into consideration. The key thing in bootstrapping is that once sample size increases then this mean and this standard deviation will be closer to that mean and that standard deviation. Let's take a look at a demonstration of how bootstrapping works. This is a video from a statistics department from University of Auckland and they demonstrate that you have your original sample here. So we have two variables. We have the x variable and the y variable and then we have a regression coefficient. So we calculate the regression coefficient here and we are interested in how much this regression coefficient the slope would vary if we were to take this sample over and over from the same population. So that's what the standard error quantifies. For some reason we don't want to use the normal formula that our statistical software uses to calculate the standard error. We want to do it by bootstrapping. So we take some samples from our original data. So we take samples from the original data like so. You can see here that each observation can be included multiple times. Sometimes an observation is not included in the sample. Then we get the regression coefficient that is slightly different from the original one. We do another bootstrap sample. We get another regression coefficient again slightly different from the original one. We take yet another bootstrap sample. We get slightly different one and we go on a hundred times, a thousand times and ultimately we get an estimate of how much this regression coefficient would really vary if we were to take multiple different samples. So that's when you get a thousand samples or a hundred samples. Then you can see that the variance of the regression coefficient is that much. A bit in the bootstrap samples and if samples are large enough, this variation of the bootstrap samples is a good approximation of how much the regression coefficient would vary if we were to repeat the same independent samples from the same population and calculate the regression analysis again and again from those independent samples. Bootstrapping can be used to calculate the standard error, in which case we just take a standard deviation of these regression slopes and then that is our standard error estimate. We can also use bootstrapping to calculate confidence intervals. So the idea of a confidence interval is that instead of estimating a standard error and a p-value, we estimate a point estimate, so for example a value of a correlation, one single value and then we estimate an interval, let's say 95% interval, which has an upper limit and lower limit. And then if we repeat the calculation many, many times from independent samples, then the population value will be within the interval, if it's a valid interval, 95% of the times. So this is an example of a correlation and we can see that the correlation estimates when there is zero correlation in the population, we have a small sample size, they vary within 0.-0.2 and plus 0.2 and most of the time when we draw the confidence interval, which is the line here, the line includes the population value. This is 2.5% of the replications here and it doesn't include the population value. So the population value here falls above the upper limit. Here we have extremely large correlations and the population value for about 2.5% of the replications falls below the lower limit. In 95% of the cases here, the population value is within the interval. So that's the idea of confidence intervals. Here we can see that when the population value is large, then the width of the confidence interval depends on the correlation estimate. So when the correlation estimate is very high, then the confidence interval is narrow, when the correlation estimate is very low, then it's a little wider here, than the confidence interval. So the confidence interval depends on the value of the statistic and also it depends on the estimated standard of the statistic. Now there are a couple of ways that bootstrapping can be used for calculating a confidence interval. In normally when we do confidence intervals, we use the normal approximation. So the idea is that we assume that the estimate is normally distributed over repeated samples. Then we calculate the confidence interval. It is our estimate plus or minus 1.96, which covers 95% of the normal distribution multiplied by the standard error. So that gives us the plus or minus. So if we have an estimate of correlation that is here, then we multiply the standard error by 1.96. Minus, estimate minus that is the lower limit estimate plus 1.9 times the standard error is here. So that gives us the upper and lower limit. In this example 1% and 13% when the actual estimate is about 5%. So we calculate how we use bootstrapping for this calculation is that the standard error is simply the standard deviation of the bootstrap estimate. So if we take a correlation, we bootstrap it, then we calculate how much the correlation varies between the bootstrap samples using standard deviation metric. And then we use that plug that into that formula gives us the confidence interval. So that works when we can assume that the estimate is normally distributed. What if we can't assume that the estimates are normal? That is the case when we can use empirical confidence intervals based on bootstrapping. So the idea of the normal approximation interval is that the estimate is normally distributed, then we can use this equation or we can use empirical confidence intervals. The idea of an empirical confidence interval is that we do the bootstrapping and then let's say we take 1000 bootstrap replications, then we take the 25th from smallest to largest, we take the 25th value of the bootstrap replicates and that is our lower limit for the confidence interval. Then we take the 975th and that is the upper limit. So that's 2.5 percent and 97.5 percent and that's the upper limit of our confidence interval. So that's called percentile intervals. So when we have this kind of bootstrap distribution, we will take a replication here, the 25th replication, that is our lower limit and we take the 975th replication here, that is our upper limit. So that gives us the confidence interval for the mean that is estimated here. That has two problems, these approach. First, the bootstrap distribution is biased. So the mean of these bootstrap replications is about 0.15 and the actual sample value for the mean is 0. To account for that bias, we have a bias corrected confidence intervals. The idea of bias corrected confidence intervals is that instead of taking the 25th and 975th bootstrap replicate as the end points, we first estimate how much the bootstrap bias is and then based on that estimate we take, for example, the 40th and 980th replication. So instead of taking the fixed 25th and fixed 975th, we adjust which replicats we take as the end points. There's also the problem that the variance, the standard deviation here, is not always the same as the standard deviation of here. So in the correlation example, you saw that the confidence interval decreased as the actual correlation estimate went up. So the idea is that the width of the interval depends on the value of the estimate. To take that into account, we have a bias corrected and accelerated confidence intervals, which apply the same idea as the bias corrected ones, but instead of just taking the bias into account, they take the estimated differences in variance of these two distributions into account when we choose the end points for the confidence intervals. Now the question is, this looks really good, so we can estimate the variance of any statistic empirically, and we don't have to know the math. And yeah, that's basically, it's true with some qualifications. The qualifications are that bootstrapping requires large sample size. There is a good article or a book chapter by Koopman and co-authors in a book edited by van der Berg about statistical myths and urban legends, and they point out that there are three different claims made in the literature. There's the claim that bootstrapping works well in small samples, and there is a fact that bootstrapping assumes that sample is representative of the population. So if our sample is very different from the population, then the bootstrap samples that we take from our original sample cannot approximate how the samples would actually behave from the real population. Then our sampling error which means how different the sample is from the population is troublesome in small samples. So in small samples the sample may not be very accurate representation of the population. So if small samples are not representative of population and if we require that sample is must be representative of the population, then bootstrapping cannot work in small samples. So bootstrapping generally requires a large sample size, then there are also some boundary conditions under which bootstrapping doesn't work even if you have a large sample. So there are that kind of scenarios, but for most practical applications only the sample size is the thing that you need to be concerned about. The problem is that it is very hard to say when your sample size is large enough.


Hey guys, I hope you guys are doing well. It is a right miserable looking day outside and I'm not supposed to go outside anyway. So let's talk about your guys's comments for Supernatural Season 15 Episode 13. You guys were, this isn't like the first one all over again. There's some brutal comments in here.  But admittedly when Ruby and what's her name teamed up I was like, wait a minute, how did these two ever meet each other?  She was one of the writers of this episode and she's just notorious, notorious for retconning stuff. So let's, yeah, nothing else better to do. So let's take a look and see how many comments you guys said. Oh, 51, geez. Starting off with the first comment here, this is actually a positive one so apparently there might not be many more of this one. Tonight's episode was actually interesting. I found the Eden scene intriguing in the sense of it brought back the mystique of the divine and the supernatural goodness feel to it versus the corporate feel of the angels and the heavens they present. That scene felt like they were expecting from heaven, what we expect from heaven and angels. I wonder who the little girl on the snake is, Eden's where humans can get their souls back? I thought the garden was, we saw on the dark side of the moon was Eden or was that something else or is this another retcon? Will be yet an Adam and Eve. Why does the empty want to stop God? I get Billy. Also does a Mara Noe above the empty and widened Mara Noe's death. Will they actually kill Chuck? Finding it hard to believe and feel like it goes against the original point message of whatever the show is. Also Chuck in season five said we needed a toilet paper to do the sea virus, croton and COVID, LOL. Finding out supernatural been on so long that they can connect aspects of it to real life events and stuff that happened to the actors. The plane issue they had on Jared's plane they mentioned that Vegas con connected to an earlier episode with a phantom in the plane to this stopping production is Chuck destroying your world of virus. Damn it was hoping for a meteor crash. I wouldn't want a meteor crash bro. Meteor crash would be far far worse than this COVID business. Quite funny how the whole Chuck hoarding the toilet paper has started to become a pretty big meme and I'm noticing this amongst people who don't even watch supernatural so as long as people watch the first five seasons that's cool. Now we're starting to get onto the critical ones here. Plot holes galore this episode. Ruby and sister Jo being buddies makes no sense because when Dean was raised from hell in season four Ruby didn't know about the angels and even if she did she was still scared shitless after seeing what they could do. Yes I remember that. Why would she be having girl time with one of them and didn't Jo fall in season nine like the rest of the angels so why was she on earth during season four when apparently she ended a sign job in heaven during the time. Also alternate reality Sam and Dean tell our Dean at the end of episode that they saw the Impala and drove it while they were looking for the occultum. How could they have seen and driven the car of Sam and Dean took it to the church where the occultum what yeah actually wait a minute what the hell but the thing that frustrated me the most about this episode was how misleading the promo was every single person I have seen talk about it on Twitter as well as myself thought this episode was going to be figuring out what to do with the other Sam and Dean TV guy even did a whole interview with Jared and Jensen oh I see what this is going to talk about and then in the episode they barely show up for more than five minutes you could have cut them out entirely and nothing would have been missed there are only two things that kept this episode for being a steaming pile of garbage for me one being Jack's moment at the end after he gets his soul back Alexander Carvette really pulled me into his performance there I like the line that where he said he should have understood their pain because his own mother died in reference to Mary's death yeah if they bring back Mary I will actually riot please no yeah please do not bring her back and other saving grace was seeing Rachel minor again it sucked that it wasn't actual Meg yes actually seeing her again was great she's a character who actually actually has stayed dead because Crowley killed her she actually turned into one of my favorite characters especially with Rachel minor the best Meg like I like the first Meg she was really good at being villainous but the second Meg she made it fun it sucked that it wasn't Meg but I'm just glad something actually managed to make me smile in this episode and I really liked how they worked around her disability by giving her a throne to set on because that's such a Meg thing oh yeah I forgot she has a mess that's why she isn't acting right now I think it's that mess but no that's actually that's a good point that's unfortunate but I'm so happy to have seen her again so we have to write a story about Jack getting a soul back let's make it utter mess let's have fun and make a self parody of our usual writing I like that thanks to the actors though it's pointless that their wives are on the show they ended Ruby's character so perfectly and it was so unnecessary to bring her back and Danielle's character what the fuck this is supposed to be the best season instead they're wasting their time giving their wives pointless screen time I'm not going to disagree because it's not wrong because I don't understand what the point of those like their cameos in this episode just I didn't get it it was fan service to the end's degree also as God said or not even batting in high at what her brother's been up to she must sense it or something damn must be an amazing vacation season kind of wonder yeah where is Amara I'm very curious because they are going to run into some issues with getting her if they haven't already filmed her yet because she's on the Mandalorian right well she wasn't the first season I'm kind of curious to see if she's going to be in the second season she's the forge master right so I'm kind of curious to see how they're going to work around because I imagine her money went this was par for the course for season 15 bring back old characters in a way that absolutely makes no sense through retcon it's not even worth picking apart anymore for places that used to be near impossible to get out of they sure are making a hell make getting out of hell and and the empty of breeze they're like revolving doors like hell it was the it was the same set even like when they went in and they're like yeah this was a trap like I said in my review this episode had like the mentality of an adhd simpson's modern day episode just next thing next thing next thing next thing it was so irritating nothing in the story mattered it just kept moving on to the next thing you're right even was already established in season five and the scene with joshua was glorious but hey let's let let's retcon it anyways also joe saying that she likes patalecki's vessel more than the blonde referring kathen and kassidy felt unnecessary mean spirit I kind of thought that was interesting too I don't know why they were so mean to kassidy like ruby has two totally different characters she has season 3 ruby which is this really kind of cool anti-hero like she really nailed the kassidy girl she really nailed this line of can you trust her you never really could but she was reliable but the knife remember the knife being like holy shit you can kill a demon with a knife that was huge being a witch and all this other stuff season 4 was a totally different ruby totally different character but I didn't complain because she realized she had to get on sam's side the scene where dean was playing with a rubber band made me laugh even the characters were losing interest in the plot I'm actually kind of don't know what that is I imagine it's when they were sitting around the table all discussing stuff going on and I imagine dean's just there with I can't remember this part but I imagine that would have been funny it takes alcohol to get through this episode geez I haven't gotten to there yet because I'm holding off on this covid thing he's going wasn't terrible but now I feel like supernatural is the jack show he's the only one getting character development this thing and the whole plot depends on what he is going to do or not and it's a bad sign aren't the winchers are supposed to be the heroes here why everything on why everything on the plot depends on jack's decisions because he is not a good character jack should have never existed they should have brought jesse the antichrist to fill the role just saying I've seen this comment actually a couple of times you guys know that he is essentially the antichrist character brought back because that was an episode that dab wrote co-wrote jack is essentially that character they didn't want to bring the jesse kid back because it's such a huge random bring back that would have been kind of more so a fan service he bring back this is a legitimate way of doing it they actually did establish how they brought jack about and yeah of course he's got character development he's only been in the show for like two seasons sam and dean have been there for 15 now and their character development stopped like season eight and then season 11 too actually they were just kind of witnesses to what was going on in season 11 and I actually didn't mind that again because I thought the season and I thought the show was going to end season 11 seeing in here I'm not complaining that jack is like a key part of the show he has to be something has to be going on and I also wouldn't call the jack show either because he's been gone since well he was gone for almost 10 episodes and then he got resurrected again for the third time in less than three seasons I disagree I thought the entire scene of alternate sam and dean talking to real sam dean was absolutely hilarious the same with the busy busty asian beauties part I really enjoyed this episode I thought it was the second best behind the pool house episode oh buddy I respect your opinion but no in my opinion this was not better as good as the pool house episode there's been a few episodes much better than this one this was not a good episode this is bad writing this is very bad writing oh this is this is a harsh one here can we just rename this episode couples were union there are so many reasons for joe and ruby storyline that makes no sense the only thing that they have in common is being married to the brothers in real life I guess that the pair up was a success if their goal was to entertain me with adorable irony anyways watching this episode felt like a sitcom without the laugh track couldn't tell if the humor was self-aware or really just flat like the characters were giving a beat of silence hoping they chuckle which is unfortunate because I feel like Jensen and Jared have proven their ability to be really funny and emotional and the script just restricts them but 80% of this episode with just slow moving storyline and fan service cameos regrettably will admit I kind of enjoyed but I didn't think it helped the story I still don't get death always being so vague especially since he consistently reminds everyone that they are under time constraints that actually that's a good point if you wanted to be getting done you need to be clear a bit of a jerk move to withhold info unless she doesn't know what the occultum is either nearly thought of they pull a pulp fiction and never actually revealed to the audience what the super weapon being a McGuffin would have been completely unlikely at this point it turns out it was just Dean Eden though so how is there not a single bit of lore on that last scene had me a little more move jack getting his soul back takes away his new character but crying over mary was personally the most attention grasping scene and leads jacks and deans relationship to a predictable but resolved ending yeah yeah almost man I was so tuned out by the end no one is talking about half no one is talking about that there is now two sands and deans in the main universe well no because they went back didn't know it oh god I really really enjoyed this episode yes it was slow but in a good way it wasn't slow though that's the thing it was just kept on going it barely stayed on anything for any amount of time that it was so boring this is the first time I've watched one of your reviews I will also be my last supernatural happens to be my favorite show for the last 15 years and I don't appreciate it someone like you putting it down well you well he is a very critical reviewer and quite objective I love it when people do that because they think they're gonna wreck me oh buddy you have no idea how much shit I went through through season 12 and 13 I figured out a way to just turn that toxicity and like turn it on its head like yes give me your comments give me your hate because I will break you I will prove my point well I guess this is how the Winchester go out getting sick by coronavirus I mean the characters not the actors I won't hold my breath for the rest of this shit show so accurate it was an okay episode and certainly better than last week snooze fest but it somehow still managed to ring hollow I kept picturing how funny alternate sam and dean would have been under kripke's watch edlin anyone yep edlin these writers want to be able to turn out soulless drivel disguised as an instant classic the ingredients are there but the measurements were wrong that's actually a really good point good way to describe it completely agree it feels more like a filler episode not sure how it's possible to have episodes that give us nothing for a whole 40 minutes and episodes that feel rushed through I did at least like the feeding part even though I thought the snake was supposed to be lucifer and maybe Joshua was a little girl anyways we can't expect the writers to actually remember facts of their own show Jeremy do you feel like season 15 has gotten better or worse since the first few episodes honestly no it's been a middle of the dam row the only good episodes that have been have been when they brought I lean back as well as the Michael one and the pool house episode but honestly that's it it's been very mediocre throughout essentially and it has it has been very mediocre throughout this season I really enjoyed this the episode seeing ruby back was cool yeah I was fan-servicing but pretty cool my issue and I've seen other people mention how was ruby met an L since an L came into the picture when the angels fell I'm excited to see what comes next just hoping they come back soon I've got a lot of comments across the board saying the salmon Dean went to Eden it wasn't Eden it was Sam and Deans wanted to see some people saw the Garden of Eden others see God's throne room for you I believe this is a bit botanical gardens where you went on a field trip with your kids thank you for clearing that up to the episode it was okay it felt like we kind of rushed and you could cut 90% of it out and still get a story at least Billy didn't have her plastic Halloween prop with her the site that music when they enter hell though I was half expecting fans of the opera to appear in front of them anyway yeah it was pretty much the jack show now Sam and Dean are just side characters I was hoping it wasn't going to be but because the show started with Sam and Dean that's how it should end but nope they've got the golden boy jack again you guys they do need something to actually end this like I it's not the jack show sure he's getting character development that's because there's nothing left for the brothers they don't have any character development left so they have to do this wow oh shit I talked for 20 minutes hopefully I can edit this down but anyways guys thank you again for your comments obviously we won't be seeing any for a while um I might try and review a supernatural season 2 episode today but I'll have to check my schedule because I'm just so busy anyways thank you guys again stay safe wash your hands and let's get all through this together especially for you guys in the states I know you definitely are going through a rougher time than us Canadians now with all the numbers so practice social distancing guys it's hurting right now I've lost all of my weddings up until June like I've got one left in June that so far hasn't canceled but aside from that I've lost a lot of my business for this year but I'm still sticking to this whole staying inside thing so make sure you do too so for me if you like this video leave a like and if you're interested in more subscribe and also if you feel like you don't like my comments make sure to leave a comment about it so you won't come back sorry that was always cracking up anyways see you guys next time


Pluton of plurals, Israeli government, intelligence services and military seem to play through different options, but the extreme ones, extreme ones, I guess, are hopefully not becoming a realistic possibility or perceived necessity or perceived best among bad options. Pluton of plurals continues. Well, and then that says in France, but Pluton of plurals, Israel coming out and saying their plan, the United States supposedly has offered this to wipe out Egypt's debt if they're okay with all the Palestinians and Gaza strip to be expelled into Egypt to live in refugee camps. Israel has already said, many members of the Israeli government have already said that they want to throw the Palestinians and Gaza into the Sinai, live in tents.   I don't know how much more extreme you could go. I guess nuclear weapons is the next stage, but committing genocide is pretty extreme.


Hey guys, happy new year to you all just want a couple of minutes of your time to share with you One of the many things I'm taking forward with me into 2021 from 2020 I'm a big believer as you guys know in making the past pay for the future in Plundering it of everything it owes us and making it paid self-forward For our future. I believe that we should take every seed from every sorrow life hands us Instead of getting trapped in the sorrow Staying there long enough sitting with the pain long enough so that the pain has a point and a purpose And makes us better humans for our future a very popular word in 2020 was pivoting wasn't it? that we were all Forced to pivot in our own personal lives in our business as churches and so on to reinvent ourselves to morph to chameleon Into a different version of us and our organizations to survive. I Think pivoting is a skill that we should all take with us into 2021 because we are not done yet Pivoting is a pivoting is a great life skill. I think we've all done it in the past But didn't call it that But many of us have done it far less frequently than we should and less well than we should Pivoting requires this internal willingness to let go it requires mental dexterity and flexibility it requires emotional range It requires a willingness to unlearn and let go of things that we find Attachment and certainty in in a way that has become indulgent and in a way that makes us get stuck in life And we're blind spotted about it But COVID came and ripped so much from us that we had no other option but to let go but to move on but to reinvent and renew And I think whatever you learned from the enforced need to pivot We should take with us into this new year Make pivoting your idea Become a master at it and in your organization Take all that you learned from the pivoting you did last year and keep it in your skillset in your toolkit in your wisdom-for-life Building that you are doing that we are all doing and let's learn how to become people and organizations That know how to pivot in lots of many ways and a lot of this isn't huge things Just on a daily basis even being able to shift weight To something that's going to work better to an idea that has more value in it To this person that should be brought closer this person that should be moved maybe to a different space To a resource or product an idea that we should pivot and give more attention to and give less attention to things that are draining us And they get in that attention just because the family and always been there pivoting I think can add so much to the planet to our businesses our families our lives our Relationships our churches if we'll keep that as part of our skillset and become masterful at it in this coming year All right, well, I'm sending much love and blessing and good energy and love and light to you all For a great 2021 let's make it Fantastic year. Why not? Love you guys. I'll speak to you soon. Thank you


Hello, everyone. I'm Thomas Lomborg. Welcome to my session called Nine Distilled Experiences for Boosting Product Management Teams. In this session, I'm sharing nine hands-on tips and tricks that I've learned during my 20 years as a product manager. Many of them come from the seven domains and nine organizations I've been working for. My real passion is to find solutions matching problems, so working with teams and customers and really innovating until you have that solution that really solves the problem. That's kind of what I'm most passionate about. My favorite acronym is Nihito. Nothing important happens in the office. It comes from Pragmatic Institute, I would say. So that's something I believe a lot in you. You really need to go out there and meet your customers. I'm based in Sweden. This session will be very hands-on. It's a very concrete advice right to the point. So there's a lot of text on these slides. I will share them afterwards so you can go back and see what was really there. I won't have time to mention everything. But yeah, let's dig right into it. Okay, so the first one. Turn feedback into qualitative data. And the problem that I've seen is that if you're not capturing all you learn from conversations with customers and partners and colleagues and whatnot, it's really hard or impossible to get the value out of those conversations. You really need to find and define a way to store that and make use of it and really convert it into data. This is important because priorities and finding the right solution to a problem is hard enough without data. So yeah, make sure you have it. You as a product leader and the product team and everyone knows how to take customer notes, where to store them, how to share them, and how to eventually report on them. And this is my hands-on tips and tricks using JIRA, where you often have requirements in JIRA and you can link those into Confluence Notes and a very neat way of creating Confluence Notes is to create a template in Confluence so that you can quickly create a new customer meeting notes page and add everything that's said in the meeting into that. There are also other tools like JIRA Product Discovery, which has a neat feature of just quickly collecting data points from many different places with one click. So you can often get away from the copy-paste way of doing it. You of course work with the team. So caption data is one thing, but you also need to share it. So ask your team and your organization to subscribe to the Confluence page with all your notes connected to Slack if needed. Make sure to have a conversation about what you learn and the best thing is if the team reaches out to you and have follow-up questions and gain interest in what's happening in the user community. That's awesome. And last but not least, set up an ID portal. Make it easy for users to create your own qualitative data. Ask them to create IDs in the ID portal from AHA, for example, and really try to boost the input of data. But once again, keep it structured and make sure you have your data readily available when you're prioritizing and working with your discovery phase. Yeah, there were some resources. Really good talk from Rob Fitzpatrick, the mom test. And you can also hear more about quality versus quantitative data and learning from Marty Kagan. Two videos I recommend. I also have a blog where you can read more about this specific topic. All right. Number two, connect users and teams during the delivery. You really want users and the development teams working really closely together. When you're writing code, when you're creating, when you're delivering, make sure to have users and the team as closely as possible. And one way of doing that is essentially to remove yourself as a PM between them. Introduce a selected few users to a selected few developers and UX persons and ask them and tell them to talk to each other and ask questions directly. Follow up, be on CC. If you invite users to your Slack channels, make sure to follow those as a product manager. Be aware for scope creep, et cetera, et cetera. But please remove yourself. Don't relay every single question and answer because that will just slow you down and it will increase the risk of not finding the optimal solution or worst case that the team becomes driven by the users and are introducing features that are not really necessary for that perfect solution. All right. Yeah, of course, I do A-B testing as early as possible, share builds, and don't forget to give users that you have worked with during the development credit when you launch. As for permission, of course, but try to use them and really show that you appreciate their feedback and cooperation. All right. Number three, write requirements, not PRDs. So product requirement documents, I see them as more or less throw over the fence artifacts to spend days and months sometimes writing these PRDs and they're the perfect means for excuses. Yeah, I was not in the PRD. So we have not developed it, right? You don't want that. My experience is that stop writing these long documents that you share with the organization. They comment on them for a bit and then you forget about it and go back and do your job. Instead, have living requirements. I think Georepics are great. There are other tools, of course, but Georepics, they work because they are close to the code and they're close to the team. They are tracked. So when you update them, everyone can be notified, for example. So work with the customer, work with the user UX development and really see the requirements as a living thing as you discover the best solution. Make sure you have enough information in them so that you can allow the team to do their work and find the best solution. Write them as if they were already implemented because you will write some release notes or do new presentations. So write everything as if it already existed. That would save you a ton of time when you're briefing the marketing team, for example. So that's a good advice as well. Yeah, don't design.  There are people that are awesome with designing UX. I think to those by all means, but don't include them in the requirements themselves. I also prefer to keep requirements short. I sometimes see every single requirement starting with as a user or product feature, XI. I tend to skip that. I mean, people get it. Keep it short, keep it easy to read. Keep it easy to get an overview of what the requirement is really about. And going back to having a live requirement, there will be follow-up questions continuously. So you as a product manager need to be ready to go back to users, customers, book new meetings to find answers to those follow-up questions. It's a living thing and be prepared to do that and keep generating and validating solutions. I've seen a lot of people that are looking up requirements into other epics. There are sometimes great ideas that may not have the validation they require just yet. Spin them out to another epic and look at it that's a later time. All right, number four. Keep your product direction up to date. As a product manager, you should have your direction clear. So that everyone knows where we're headed, why we're doing it, what are short-term and long-term challenges. What do we really need to innovate about? What problems are out there? That's something you should always have up to date and keep fresh, including the actual presentation of your direction so that everyone can go in and find it, which means the engineering team. You should never share it with the sales team or with the customers in electronic form. So please make sure that you are the one presenting it because you want the feedback from it. Having a direction presentation is the best thing to generate interest in your company, in your product, and the most engaged users tend to show up to direction presentations and that's what you want. That's where you want your feedback to come in from, right? And you will also broaden your contact network. Make sure to write down, as we said previously, you should have a process for how you collect quantitative data or quality of data, and make sure to do that from these presentations and add everyone that was in the direction call to those nodes with email addresses preferably with roles as well so that you can reach out at the later point. You never know when you're building what and it's always great to have references to users and customers that are engaged and willing to provide more feedback. What should be in the direction? Well, a safe harbor, the future will change so always have a safe harbor slide in the beginning. Contact details, of course. You want feedback and questions. Pitch the company and products just to remind everyone about what you're here. And then a summary is great because the direction is full of stuff that has not yet been implemented. So remind everyone that yes, we are actually releasing quite a few valuable solutions and just highlight some of those too to show that this is an awesome point to direct to an ID's portal. For example, if you have an HAL ID's portal you can show what has been implemented of all the IDs. All right, and then of course focus on what you want feedback on. Focus on the near-term solutions you're about to deliver. That's what your focus should be about. I'm getting into the actual content a bit later on here in number five. Team up with your sales team. And the directions presentation is one of the most valuable tools when you're in meetings with customers and your sales team. However, in this scenario you should be ready to adjust your direction presentation. Tune it and tweak it on your way to the meeting as you learn what this customer is more interested about. Just hide slides or shuffle slides around. Tune the message. Make sure that the customer and the sales team gets as much value out of this meeting as possible. This is their meeting, not yours. So talk about the topics that they are interested in because they will provide the awesome and valuable feedback about the areas they are interested in. If you start presenting the whole product direction and they're not interested in half of it, it's just a waste of time. So be prepared to adjust your presentation. Don't commit to anything, of course, not to customers, not to sales. Don't talk for quarters months or any timelines. Treat also the sales team as a customer because if you share things on your way to a customer meeting, for example, there is a big risk that the sales rep will use that in some way and you don't really want that. So please don't commit or talk timelines at all. You will get rewarded with a lot of insights and my way of paying for those insights is to be transparent. Tell the customer and the sales team what has lower priority, higher priority. Share what you're uncertain about. If you are uncertain about something, you're in the discovery phase, let them know that and ask for feedback or dialogue, follow-up meetings to decrease the uncertainty. Also, let them know what will not get done because if they are requesting something over and over again and you know that you will not do it, say that. But also tell them why. Tell them if it's related to cost or tech or direction or priorities. Just let them know that and find alternative solutions and try to be innovative and go back to the core problem of why they are requesting something that you can't deliver. So, once again, be transparent. Yeah, of course, don't share the direction deck and be personal. Be nice. Ask questions. Be curious. Ask the why again and again. Yeah, make sure your live demos work. Sales reps and customers, they love live demos. So, make sure they work. Worst case, have a video ready. Don't use it if you have internet connectivity and you need that for the demo. You should demo. But worst case, have some kind of emergency backup. If possible, prepare the engineers back home so that you can answer questions on the fly that are super technical. Maybe your team can be a slack message away and you can have an answer quickly within the meeting and really surprise the customer with that and how you work together with the engineering team as a product manager. Claim your own demo booth at conferences. That's also an opportunity to get a lot of traffic, a lot of interaction with sales rep marketing customers whoever passes by potential partners. Don't let the demo booth go to someone in pre-sales or sales or anyone else. If you're there and your product manager have your own demo booth. All right, number six. Being a product owner is about 10% of a product manager's job. But it's also very much your job. And I know it's easy to get caught up in team activities. You're spending all your days as a product owner slash project manager. And that's really not where you want to be. However, you want to be close to the team. You want to monitor the team. You want to serve the team with insights. Ask any questions. Really leverage your network as a PM to support the team in the best possible way. And you also, and this is probably the most important thing, you want to close the gap between users, customers and the delivery team. So having a separate, worst case separate product owner between a PM and the team is just the worst thing. You're just increasing the distance between users and your team who should be innovative and deliver the best possible solutions. Why would you introduce additional roles between them? Because that's just not feasible. So be a product owner, but try to reduce the number of hours you spend on typical product owner tasks and work closely with the team. Join the team, it is when you can. Try to be the ones to start the meeting so that you can have your things said early. And then the conversation tends to be more and more technical and then you can drop off if you have other things to do or just listening. Try to encourage working with customers and give the team credit for that. Ask the questions, of course. Ask if there's anything you can do, any information you can give the team through your network.  You have the most awesome network. You know stakeholders, you know engineering managers, you know customers, partners. You have a great network with a lot of potential to provide feedback to the team, right? So try to do that. Be observant to a scope creep. That's something that happens sooner or later. So be on top of that. Once again, make sure your demos work. As the team develops more capabilities, it's easy to forget that there should always be a working demo. So try to be on top of that. And it should be your demo, not something that a developer can spin up in their development environments, right? Are you talking about stores and tasks too much? Try to avoid that. Keep your conversation on Epic level and leave it to the team to define stores and tasks. That's not really your job as a product manager. Have you inherited a messy and long backlog? That has happened quite a few times. There's no way around it. You need to block a week or more to just sort it out, get it in order. You will never get a messy, long backlog completely in order. But try to focus on creating a top one-third of it and really have that prioritized and fill any gaps with qualitative and quantitative data. All right, number seven, UX and design innovation. The problem here is that UX teams tend to enhance the existing product and they do that really, really well. But sometimes they forget to be innovative, to research new trends in user experience and design, and your product is kind of stagnating as it comes to look and feel and how it's perceived. It tends to feel more and more dated over the years. So as a product manager, and especially if you're a lead or a director of product management, make sure to request and sponsor UX and design innovation. Make sure that's something that you do continuously. Show everyone that you are doing it. Be honest with timelines and when it might make it into the product, but do it continuously. Always try to find new ways of navigating your product, color schemes, look at fonts, look at how your product is perceived, and do that. And if needed, print out those designs and hang them on the walls in the office. Make sure this is something you do continuously, to avoid your product feeling dated and embrace new ideas in UX. Yeah, if you want to hear more, I recommend Product Talk, where you can listen in on products, cover product delivery, and also Product Hunt. A lot of great products are presented there, and many of them have really innovative and nice UX and designs. We'll check out those two sites. Yeah, go full stack. When you're innovating, go full stack. Don't just innovate within your team. Bring in the whole product, look at it holistically, see if there's anything you can do together with other teams to really be innovative. Don't forget the business case. Don't bring in the business model as a product manager. You know the business. Bring that into the innovation. Be honest about the current problems you're trying to solve so that you're innovating in areas that are important to you and the company. Avoid innovating just within the UX team or in a feature team or product team. Innovate on a higher level. Make sure it's on the top product level. Yeah, I think that's it on UX and design. So let's move into tips and tricks. Number eight, keeping a sense of urgency in agile organizations. So the problem I've seen is that in agile organizations and feature teams, it's easy to end up in a sense that there is always another sprint, another release, nothing is urgent to deliver right now. There's always plenty of time for side projects and process enhancements. And this is, yeah, as a PM, especially as a product manager, this is a really tough situation to be in. You want to be agile, you want to discover the best solutions, you want to deliver in the end. And having this kind of mentality that, yeah, we didn't make it, but maybe there's a new release within two weeks, so why would it matter? This is being agile and working in product teams has nothing to do with losing a sense of urgency. It's not a reason for running like a headless, safe, waterfall approach or anything like that. But please try to be personal.  You know the problems out there. You know what needs to be solved and you have names and references for why. So mention those names. Mention those contacts. Introduce developers to those contacts having those problems so that you raise the urgency and you make it personal, not only within the team, but also personal with actual users waiting for your solutions and features. So make it personal, make it fun. Try to get team members to help each other. Don't forget to celebrate and really find that perfect balance between backing off and pushing the team. And you will do great. The other advice is to be demo driven. Always demo what you do. Create end-to-end demos. Request demos to be possible to run by you as a PM so they are not engineering versions. So demo yourself and demo early, demo to the company, demo to customers or share builds. That's my other advice. Yeah, validate it with customers, of course. And last but not least, don't accept the, yeah, but this other team is releasing later so we can wait until they are done because, yeah, why would we push something out now when they will not be ready anyway and we will just have our stuff laying on the shelf. Don't buy that. Make sure to deliver on time, deliver quality, solve the problem and move on. Don't take external dependencies as an excuse for having projects running unnecessarily long. Right, we are already at the last tips and tricks and that is competing product areas. What do you do when your problems are not always considered the most important to solve as a PM? This can be really frustrating. You have collected all the evidence. You have the notes. You have tons of IDs in the ID portal, but your organization has other priorities. This can be really frustrating as a product manager. If this happens, and I believe it will sooner or later, remember to represent the product team. If you're a product lead or a product manager, act as a team, stay behind the direction, the vision, the strategy you have laid out, communicate that as one team. Even if it currently says that your favorite features and solutions have lower priority, communicate what you have agreed upon as one team. This could be kind of a competitive situation. You really feel for your customers and your features. Keep collecting data and communicating customer paints. At this point, it's important that you're super clear about what's needed within your product area. Continue to collect data. Continue to be clear. Find new ways of communicating it. Maybe present part of it in company meetings. Just remind everyone that the problem is still there, even if it has lower priority, and make sure that when other things are decided, make sure that everyone knows what is not getting done. Because that's your responsibility as a PM to tell people making decisions above your head what the impact will be, what will not get done, what solutions will not reach end users, and what could the impact be? For example, they may churn on certain use cases. Maybe they won't use your product to solve certain problems, which means they will bring in competitive technology into the mix, and that's high risk, of course. So just be transparent and keep collecting it. Also, read up on what's actually the most important thing right now. Read up on that. Learn. Support them. Collect quality and quantitative data for that solution. Maybe it's actually something you would like to move into as a PM. That could be your next career step. Validate the most important solution right now with your customers. Maybe you can find a match between their needs and what you have been talking about in this new strategy. So use it as well. And inform your team. Inform your team that the decision is here. These are the new priorities and work and support your team in that. All right. That's nine tips and tricks and some experiences as a product manager. I would like to say thank you and I will be happy to continue talking to you on Discord. Or you can just reach out on my Gmail or LinkedIn. Thank you very much for your time. Have a great day.


What amazing lady. I met her three years ago now when she was coming out of the hospital and she was very ill where her lung specialist didn't think that she actually had much time to live. So I was scared to death. I didn't want to come to palliative care. I said I'd rather go to hospice. Later on I found that they're they're one in the same but which are from purposes. Oftentimes our sickest patients need extra support and sometimes they need to have difficult discussions around that and they might be bumping up against the limits of what medicine may have to offer at times and it becomes more about what's important to patients at that point and how do we tailor a medical plan that supports that. And palliative care is to get you from where you're at and move forward. Palliative care can be used as just an extra layer of support at any stage of people's illness. So at Kaiser Permanente we use a team approach in our supportive care. You have a nurse, you have a doctor. We have a social worker on our team as well for addressing any gaps in their care in terms of social needs. Perhaps they need help with transportation or financial help. Our social worker also has specialty in assessing coping styles and promoting healthy coping with serious illness as well. In the home setting we have some CNA care who can help with when people get weaker bathing, dressing, that sort of thing as well. So it's a multi-disciplinary approach. So that whole team is with you throughout. Included in that team is a physical therapist and they come, they all come to me. I don't have to go out for anything. We address patients needs in three different settings. We can see them in during a crisis in the inpatient setting in in the hospitals. We can see them as outpatients in clinic and we actually have a home-based service as well for people who are homebound. Palliative care makes me feel wanted, cared for and I get a warm feeling in my heart.


Something always makes me come back to talk about this group. Maybe it's because their songs touch my soul so deeply. Perhaps it's their raw talent and relentlessness and inspiring work ethic. Or maybe... maybe it's just because they're so good looking. I feel like there's nothing I can say about them at this point that you guys wouldn't know about. You guys have heard me talking about them for probably hours now. Well, I figured enough talking about them. Time for a taste test. If you guys have ever tried to get concert tickets before... Oh no! What is this? I don't need to tell you how hard it was to secure these. Well, thankfully they did give us a code to buy the tickets early, but like hundreds of thousands of people had the same code. Thankfully we were able to clutch four tickets. Nosebleeds, of course, but... you know... life goes on. So with my bags packed, a ticket to LAX and some SoFi Stadium nosebleed seats, we headed out to California. LA, Tinseltown, La La Land, the City of Angels, and home of the worst traffic jams in the United States. We were headed to Englewood. After a quick car rental, a stop at the Amazon grocery store for some Red Bull, and a $100 event parking spot, BTS! BTS! BTS! we were finally there. Alright, Vera, who are you excited to see? V! Why V? Because he's freaking hot. Matt, who are you most excited to see? Jimin. Why? Because he's freaking hot. SoFi Stadium, one of the newest and largest stadiums in California, welcomed the overwhelming masses of BTS fans. It was one of the highest concentrations of K-pop fans I've seen in my entire life. Roughly 50,000 people were lined up around the entire stadium, and 50,000 ARMYs strong. That's bigger than some cities. While we were in line, we had time to chat with a few of our fellow ARMY. One of the things that really caught my attention was how fans came in all shapes, sizes, and walks of life. They're just gorgeous, and then also their music. Once you just start really digging in, their work is so amazing. Their body of work is so impressive, just no matter how you look at it. My daughter's been ARMY for about five years, so she kinda got me into it. You're right here with your daughter. We had tickets for the Dallas concert, and then they canceled the tour, and I got these, and she's like, I can't give us two whole days of school.  We came from Israel, all the way from Israel to the concert. Yeah, so we bought tickets for yesterday, and we didn't have seats. We didn't have seats. We sat on the stairs. Someone took our seats and we sat on the stairs. So we wanted to have a better experience tonight, and all the tickets are like for 5K, so we can't get high. So we're trying to get for like 1,000 for a ticket, but it's not enough, it's not even enough, and we're outside, we don't have tickets. We started driving at 9pm, and then we got here at 6am, got my car towed, and now I'm here through Uber. Look, it's Tanjiro. What? Tanjiro! I wonder who this bias is. The SoFi Stadium is still brand new, it only opened last year, and this is only the 7th concert ever performed at the stadium. The structure was imposing, and quite frankly, intimidating. As we walked down the long concrete hallways, BTS songs all the new blared with the audience clapping and singing along. So, water, water, $5. And $5 water bottle. It should be the best water I've ever drank in my life. When the boys finally came out, well, I don't have to tell you guys.  However, actually being there and hearing them sing live, being in the same room as them, and breathing the same air as them, it's an experience that's incomparable to any other. Despite the nosebleeds, we thoroughly enjoyed the performances, especially since it gave us such a full view of the entire stadium, which was a treat when it came to the cool light stick animations. Being the very last day of the concert, Jin allowed us to celebrate his birthday with him. And if that wasn't enough, Chris Martin from Coldplay came out as well to perform My Universe. And that was something that was exclusive to those in attendance on the very last day. And with that, the dream that I didn't want to end came to a close. The members of BTS concluded with some final words to the fans, and as painful as it was, it really felt like a farewell, at least for a while.  I'll always remember the day that I waited for me so happily. Four days, I spent with you. I'll make sure they never made a way for my memories. I didn't know that it would take so long, so I did my best as if it was the last stage. I've been waiting for days when I could be alone like this. I feel so blessed and grateful that I could do this in this crazy time. Four nights, it's so precious. I hope this concert is not the end. I hope that it's another minute. I'll always remember today until we meet again. Isn't it all a little poetic that BTS's last overseas concert, at least outside of Korea and Japan, took place in the same city as their very first concert? Again, it's like poetry, sort of, they rhyme. As they drove through the Los Angeles city streets for the last time in their foreseeable future, I wonder if they reflected upon that and how far they've come. You're so beautiful. Of course, this is assuming that Jin and the others won't be exempted from military service, about which there is plenty of discussion among Korea's National Assembly. If passed, the new law would revise the Military Service Act, and it's already been dubbed the BTS law. As of right now, the status of BTS's enlistment has been granted a postponement by the South Korean government, but they're only in a state of limbo. Eventually, decision will have to be made by the government to either go forward or formally exempt them. Really, only time will tell, but one thing is for sure, this won't be the last we see of them. Where are you guys from? Japan. Oh, you guys are from Japan. So you came here all the way to America just to see BTS. That's crazy. How was the concert? It was amazing. I blacked out. I don't even remember it. That's one group that's like the Rolling Stones, Michael Jackson, the Beatles, all rolled up into one on super steroids. Long as I've been working for this company like six and a half, almost seven years, I've never seen nothing like this. I thought it was really great. They're teaching the kids and technically everybody to love themselves. And they're just being such a good influence. They are just what they are. Nothing can change how powerful they are. They're starting to open the door, not just for BTS, but for the whole K-pop and the whole Asian culture. I feel like it's not just on a music level. They're so far beyond that. They speak at the UN, all the charities they do, how much they put into stuff that's not related to music. It kind of comes together and makes the music even better. It kind of went by too fast, like a dream. But I wouldn't trade it for anything. Perhaps it's appropriate that all of this is happening during the season of joy and grace and thankfulness. They've shared so much of their passion, their music, and themselves with the world. And no matter what happens next, I'm just happy that I was there for it.
