A few weeks later I received another email from a different sender. The message, with slight wording differences, was es

Then, early in the morning on August 14, 2019 — two weeks from my son’s 18th birthday — I got a call from the King County, Washington sheriff’s office that there had been a report of shots fired at my house. I was across the country, getting ready to head home from a conference. We do not own any guns, and my son doesn’t have any friends who own guns, so I knew there was a strong chance this was a hoax. But what if. They were going to send officers to my home.,There will be a role for people who look like me, but it’ll be a role that we’re very unaccustomed to: listening rather than speaking, giving before we take. It’ll be as part of a community, and if we’re lucky we’ll have as much chance to succeed as anyone else in that community. And the community’s welfare will be the most important barometer to success. If we’re lucky people will treat us better than we’ve treated them.,And all that leads to my main event: 15–18 hours of battery life on the Air. And 17–20 hours on the Pro. 20 hours! Apple is usually pretty honest about such assessments, so if we can trust them here, this is incredible. And while the ability to fully control the stack and not have to put up with Intel’s always-delayed roadmap may be the main reasons to do their own silicon, this has to be the top side effect.,As the threats of suicide piled up, I began to see a coordinated campaign to harass me, and as disturbing as it was, it was also sadly fascinating in what it revealed. These men were trying to terrorize me with what they saw as the only logical conclusion to my anti-racist, feminist work: the mass suicide of white men. They wanted me to know that they saw my work to end violent misogyny and white supremacy, and they saw that it was a threat, not only to their norms and their status but to their very lives.,Statistics is also essential for machine learning. We will use statistics to understand the data prior to training a model. When we take samples of data for training and testing our models we need to employ statistical techniques to ensure fairness. When evaluating the performance of a model we need statistics to assess the variability of the predictions and assess accuracy.,These are just some of the ways in which statistics are employed by data scientists. If you are studying data science it is therefore essential to develop a good understanding of these statistical techniques.,You can turn your shame and discomfort into rage, as so many Trump voters did, or you can own it. You can claim it, because it’s yours. And in so doing, you can keep from passing it on to the next generation. You can be a better ancestor than the ones you got. You can be a better ancestor than the ones I got.,I sent a neighbor to go knock on the door, then on my son’s window. My son had been sound asleep, unharmed. But the police had received a call from someone pretending to be my son and stating that he had killed two people in the house. They were going to send an armed response. To my home, where my son was alone and barely awake and very confused.,It has been years since that terrifying time for my family. We worked with some great therapists, spent a lot of time healing together, and my son grew out of his hardest phase. Not all families are so lucky. Sometimes there is no intervention that can save our children from the claws of anxiety and depression. It has only been in the last two years or so that I’ve been able to relax somewhat — feeling confident that we made it through the worst of it, that I was going to see my baby grow into a man.,The teenage brain can be a very dangerous place. As young people grow and get ready for adulthood, their world is rapidly changing — as are their hormones. A great day is often the best day of their life and a bad day is often the worst. And if you ask a teen how they are doing on a bad day, if they are willing to talk to you at all, you may hear that every day they’ve ever had is bad, and every day they will ever have will be bad. Teenagers often have difficulty projecting themselves into a different, better future. It can be a very scary time, and the consequences can be very real.,There will be a role for people who look like me, but it’ll be a role that we’re very unaccustomed to: listening rather than speaking, giving before we take. It’ll be as part of a community, and if we’re lucky we’ll have as much chance to succeed as anyone else in that community. And the community’s welfare will be the most important barometer to success. If we’re lucky people will treat us better than we’ve treated them.,These men wanted me to know that they were miserable, they felt screwed over, and they felt demonized. They wanted me to know that the only option available to address white male patriarchy was either to maintain the status quo that was making us all miserable, or death. They wanted me to know that they were not capable of growth or change and that any attempts to bring about that growth or change would end them.,I could have lost my son, the driving force of my heart and soul, to this despair. I’m forever grateful that part of him wanted to live, and that part decided to reach out for help.,I am the mother of two boys. Two beautiful young men who were born as beautiful babies full of endless possibility. It was shocking to watch how quickly the patriarchy came to claim my sweet little boys. They weren’t even in preschool before I had to battle a world that wanted to take everything that was soft and kind and generous about them and turn those traits into hardness, cruelty, and dominance. I watched my older son, who had the most brilliant smile I have ever seen, struggle under the weight of being repeatedly told by society that his loving, open nature was a weakness.,Statistics is a fundamental skill that data scientists use every day. It is the branch of mathematics that allows us to collect, describe, interpret, visualise, and make inferences about data. Data scientists will use it for data analysis, experiment design, and statistical modelling.
