My 12-year-old daughter asks me: "Why can't I have my own cellphone? Everyone else in my class have one. Without a cellphone, I cannot make friends with them, and I cannot join their conversations. I feel lonely and sad." How to properly respond to my daughter? Shall I give her a cellphone or not?

Dear daughter, I truly understand your feeling, and I don't want to keep you feel bad at school. I'm willing to give you anything that I can reasonably afford that makes you happy. However, I have some concerns that giving you a cellphone might harm you instead of making you happier. Can you address my concerns and make me feel safe to give you the cellphone? Here are some of my concerns: 1. Using cellphone too much would harm your eye sight. Especially for teenagers, whose eyes are still growing, it's very easy to have near-sight pretty quickly. 2. Using cellphone too much would take too much of your time, and you would spend less time reading books, doing exercises, playing outside, talking to people, which harms your overall development. Adults like me already ready lots of books, did lots of exercises, and talked to a lot of people when I was a teenager, so I already developed those skills. 3. Using cellphone too much would make you feel hard to focus on one thing. The scattered information would stimulate your attention, and make you feel excited at superficial contents, and don't think deeply. 4. You might accidentally lost your cellphone, and you will feel sad about it. Teenagers usually are more likely to lost things than adults in general.

What's the relationship between aperture and shutter speed?

In photography, aperture represents the size of the opening in the lens, and shutter speed represents how long the shutter remains open to let in light to expose the image sensor. If you keep exposure constant, they have an inverse relationship. Opening the aperture wider results in shortening the shutter speed, and having a longer shutter speed means closing the aperture more.

How should I sleep train my baby?

Make sure the room is dark enough. If you hold out your hand at arm's length, you should not be able to see the outline of your fingers. Get a sound machine so that outside noises do not disturb them. Use a sleep sack or a swaddle as a safe method of keeping the baby warm. Lastly, maintain a consistent routine every night which may include reading books, giving a bath, feeding them milk, and/or singing a song.

What are some pro tips when cold calling?

Cold calling is more art than science. The primary mistake people make when cold calling is in defining what success looks like. For most sales roles, the goal of a cold call is to establish rapport, not to book an order. Think about it - when was the last time you purchased something by phone the first time you were contacted? Odds are that several follow ups were required before you were ready to buy, no matter how qualified a buyer you appeared to be. Establishing rapport means getting your prospect to open up, because he/she has determined that you are worth the time to do so. So the keys to establishing rapport are simple: be courteous and respectful, provide appropriate context, and be OPEN. Let's consider each of these individually. First, courtesy and respect- after briefly introducing yourself, ask the prospect if now is a good time to talk for a few minutes? We've all experienced the annoyance of a caller who dives right into the conversation immediately after hearing a "hello". Be respectful of your prospect's schedule and give him/her an "out." If it's not a good time, you're not going to have a successful call no matter what you try. Next, provide appropriate context. Don't assume he/she knows nothing about what you are trying to sell. If that were the case, this prospect wouldn't be a very good target for you! Prepare a short introductory statement that can be delivered in a genuine way with a friendly tone. For example, "I'm with ACME Mobile Window Repair and wanted to share some spring promotions with you - have you seen our trucks around your neighborhood?" Setting context will help build rapport by providing a clear understanding of why you are calling, and what you hope to get out of the conversation. Successful sales people are very comfortable with the fact that they are trying to sell something. Own it, but do so in a low key and friendly way, and this will help lower the defenses of your prospect if he/she sounds guarded Lastly, be open. This means open to going off script, open to hearing about competition or open to negative impressions of what you're selling. An open dialogue allows room for questions, both from you and from your prospect. Think about an enjoyable conversation you've had lately. Was it a natural back and forth, with questions posed and answers provided? Did the questions take the conversation into a deeper dialogue? A successful cold call is one that feels like a natural conversation about a topic of shared interest. If your prospect goes off on a tangent, don't redirect too soon, or better yet - ask a question - "I'm curious - What made you think of carpets when I mentioned windows?" If he/she goes negative about your offering, ask another question - "What in your experience has caused you to feel this way?" Cold calling is a skill that can improve with practice. The more comfortable you are being courteous, setting context, and remaining open, the better your sales outcomes will be. And it never hurts to smile - even over the phone!

Can you write a brief summary for the book "Braving the Wilderness" by Brene Brown?

Braving the Wilderness is a book about belonging, identity, and leadership. A core idea is that if you are courageous enough to stand alone in the name of the virtues and values you believe in, you can actually create more belonging for others. To brave the wilderness is not to go into the woods armored and ready to fight, but with an open heart and conviction steadying your spine.

How should I go about planning a trip to Europe?

Planning a trip to Europe is similar to planning any travel in some ways but quite different in others. This is because Europe is a diverse continent made up of countries each with their unique culture, geography and climate. Moreover, every country has something unique to offer by way of things to do. Therefore, while planning your trip to Europe, first consider what kind of experience you want, for example, whether you want a more modern holiday or a rustic vacation, whether you want to spend time on the beach or rather partake in winter sports or activities. Consider also whether you like warmer climates or enjoy winter weather. Once you have established that, consider your budget and for how any days you can travel. After you decide on all those parameters, you can create your travel itinerary and either do your travel booking yourself or approach a travel agent to do it for you.

Is there a Santa Claus and who is it?

While there was a Saint Nicholas who existed in history the current "Santa Claus" is a fictional character used as part of the celebration of Christmas. According to the narrative Santa Claus keeps a list of boys/girls and tracks to see who has been good and bad. Based on this list he will fly around the world in a red sleigh pulled by reindeer. As far as entering each home he will use a chimney if available or some other means. The historical Saint Nicholas of Myra who was born around 270 A.D. has attributed to him the habit of secret gift giving to those in great need and not expecting it. Current western culture representations of "Santa Claus" have their roots in an ad campaign commissioned by Coca-Cola with art by Haddon Sundblom and debuting in the 1931 editions of the Saturday Evening Post and other magazines.

Many people are hesitant to invest resources toward slowing down or even reversing the effects of climate change because they think it does not make sense if only a small portion of the population invests resources. They think it is stupid to do so until everyone agreed to do so or is forced by policy. What is the reason that some people still do so?

Some people do not want to wait until everyone agreed or a policy is in place because they want to start or increase the momentum of slowing down or reversing the effects of climate change. They don't want to wait until it is potentially too late but rather they want to do what they can right now. Some of them might hope that those actions motivate others to follow them which might in turn increase the chance of more and more people doing the same and thus likely starting a bandwagon effect. Some of the activists might also want to prevent living with a bad conscience and thus, they might prefer to spend their resources on climate change related causes instead of other alternatives.

Why are there speed limits on public roads?

Governments create and enforce speed limits for humans driving vehicles on public roads in the interest of public safety. The speed limits generally depend on the type of road, including whether it is in a residential area or a freeway.

By preventing vehicles from traveling at excessive speeds, speed limits help keep roadways safer for everyone.

What are the main components of Apache Kafka?

Apache Kafka is a distributed system that is composed of several components. The main components of Apache Kafka are: - Topics: A topic is a category or feed name to which producers can send messages and read by consumers. It’s append-only and immutable. Consumers can use an offset to track read messages. - Brokers: A Kafka cluster is composed of one or more brokers that manage the storage of messages in topics and serve as intermediaries between producers and consumers. - Producers: Applications that produce data and publish it to one or more topics in a Kafka cluster. They control how events are assigned to partitions within a topic. - Consumers: Applications that subscribe to one or more topics and consume published messages. The only metadata retained on a per-consumer basis is the offset or position of that consumer in a topic. This offset is controlled by the consumer. - Partitions: Kafka uses partitions to split a topic's messages across multiple brokers for scalability and performance. Events with the same event key, such as the same customer identifier or vehicle ID, are written to the same partition, and Kafka guarantees that any consumer of a given topic partition will always read that partition’s events in exactly the same order as they were written. - Replication: Multiple brokers always have a copy of the data to guarantee high availability and fault tolerance. This replication is performed at the topic partition level.

Snowboarders might say snowboarding is better because snowboard boots are more comfortable and easier to walk in.

How do I cast on a knitting project?

Casting on is how to make the first row of stitches. Each method of casting on can look and feel slightly different (such as various levels of stretchiness and flexibility) so most knitters have their preferred cast on method. Many use the long-tail cast on method which can work for many projects. First, measure the length of yarn that is about 4 times as long as the width of your project. For example, if the width of your project is 10 inches, measure out a 40 inch piece of yarn. Next, time a slip knot. Then, place the slip knot on your dominant hand’s needle with the yarn tail closest to you (the tail is the length you measured out). Hold both strands of yarn with your non-dominant hand. Spread the two strands of yarn out with your thumb and forefinger, then bring the knitting needle in your right hand to the front of the tail of yarn draped over your thumb. Bring the needle back, up and through the loop toward your thumb loop, then push the needle back and under the forefinger loop, allowing the needle to catch the forefinger loop and allowing the thumb loop to fall off under the needle. That’s your first cast on stitch. Repeat the steps for the total number of stitches you need.

What is cholesterol and bad cholesterol and why would I want to reduce my levels?

Cholesterol is a waxy, fat-like substance found in the cells in your body. Your liver makes cholesterol and it is also found in some foods like meat and dairy products. Your body needs certain levels of cholesterol to function, but too much raises the risk of cardiovascular disease. LDL, low-density lipoprotein, is also known as bad cholesterol. It gets it's "bad" name because too high of levels of LDL can lead to a build up of cholesterol in you arteries. The extra amount of LDL forms plaque and the build up of this plaque in your arteries leads to a condition called, artherosclerosis. Coronary artery disease happens when the plaque buildup is in the arteries of your heart. It causes the arteries to become hardened and narrowed , which slows down or blocks the blood flow to your heart. Because your blood carries oxygen to your heart, this means that your heart may not be able to get enough oxygen. This can cause angina or chest pains and may lead to a heat attack if blood flow is completely blocked.

What is the history of the saxophone?

The saxophone was invented by Adolphe Sax, a Belgian instrument designer who was born in 1814 and died in 1894.

How Is Linux Licensed?

Linus has placed the Linux kernel under the GNU General Public License, which basically means that you may freely copy, change, and distribute it, but you may not impose any restrictions on further distribution, and you must make the source code available. This is not the same as Public Domain. See the Copyright FAQ, ftp://rtfm.mit.edu/pub/usenet/news.answers/law/copyright, for details. Full details are in the file COPYING in the Linux kernel sources (probably in /usr/src/linux on your system). There is a FAQ for the GPL at: http://www.gnu.org/copyleft/gpl-faq.html. The licenses of the utilities and programs which come with the installations vary. Much of the code is from the GNU Project at the Free Software Foundation, and is also under the GPL. Some other major programs often included in Linux distributions are under a BSD license and other similar licenses.

My daughter's friend is lactose intolerant. What foods should we avoid when we take out to eat with us?

You'll want to look out for anything that contains milk, butter, cream, buttermilk, cheese, or ice cream. This means pizza is off the table (it almost always has cheese), and much Italian cuisine like lasagna or alfredo sauces must be avoided. You also need to be careful about fried foods, because batters often contain milk or buttermilk. Ask about the ingredients of bread, as these can contain butter: croissants typically do. Even salads can be a concern, because many restaurants will add cheese as a topping, even without listing cheese on the menu. Desserts are also problematic, because chocolate nearly always contains milk, as do most ice creams. Look for vegan products where you can, such as vegan cheeses and vegan ice cream, which can be delicious.

How can I change the type of a column?

What Is Linux?

The name "Linux" is used to refer to three similar yet slightly different things, which can be confusing to all but the hardcore geek. The three usages vary by how much of a complete software system the speaker is talking about. At the lowest level, every Linux system is based on the Linux kernel — the very low-level software that manages your computer hardware, multi-tasks the many programs that are running at any given time, and other such essential things. These low-level functions are used by other programs, so their authors can focus on the specific functionality they want to provide. Without the kernel, your computer is a very expensive doorstop. It has all of the features of a modern operating system: true multitasking, threads, virtual memory, shared libraries, demand loading, shared, copy-on-write executables, proper memory management, loadable device driver modules, video frame buffering, and TCP/IP networking. Most often, the name "Linux" is used to refer to the Linux Operating System. An OS includes the kernel, but also adds various utilities — the kinds of programs you need to get anything done. For example, it includes a shell (the program that provides a command prompt and lets you run programs), a program to copy files, a program to delete files, and many other odds and ends. Some people honor the request of Richard Stallman and the GNU Project, and call the Linux OS GNU/Linux, because a good number of these utility programs were written by the GNU folks.

What are some of the challenges when walking with crutches?

You will probably find it intuitive to use crutches to move around flat areas when you have a leg injury. You may not immediately know how to safely move up and down stairs with crutches, but there are many videos on the Internet that show clear examples of how to do so, with or without a handrail as support. One of the biggest challenges when using crutches is that they make it difficult to carry items from one place to another, because your hands are always holding the crutches. To overcome this challenge, it can be useful to have a backpack or a bag to help you carry things around while holding onto the crutches. Walking for long periods of time with crutches can also make your hands feel sore because they are not used to bearing your bodyweight for very long. Finally, it is important to make sure you always set down your crutches in stable positions against walls or furniture, as they can easily be knocked over by accidental touch or household pets.

The Dursleys consider themselves perfectly normal, but at the age of 11, Harry discovers that he is a wizard. He meets a half-giant named Hagrid who invites him to attend the Hogwarts School of Witchcraft and Wizardry. Harry learns that as a baby, his parents were murdered by the dark wizard Lord Voldemort. When Voldemort attempted to kill Harry, his curse rebounded and Harry survived with a lightning-shaped scar on his forehead. Harry becomes a student at Hogwarts and is sorted into Gryffindor House. He gains the friendship of Ron Weasley, a member of a large but poor wizarding family, and Hermione Granger, a witch of non-magical, or Muggle, parentage. Harry encounters the school's potions master, Severus Snape, who displays a dislike for him; the rich pure-blood Draco Malfoy whom he develops an enmity with; and the Defence Against the Dark Arts teacher, Quirinus Quirrell, who turns out to be allied with Lord Voldemort. The first book concludes with Harry's confrontation with Voldemort, who, in his quest to regain a body, yearns to gain the power of the Philosopher's Stone, a substance that bestows everlasting life.

When the splitboard is split in half, you adjust the bindings so the setup looks just like a ski setup. After you split the board, you put climbing skins on the bottom of the splitboard to give you traction on the snow. After reaching the top of your destination, you remove your feet from the bindings, remove the skins and then put the splitboard back together. Once the splitboard and bindings are reassembled, you snowboard down the mountain.

When do avalanches occur?

Avalanches are primarily caused by unstable snow conditions. Although a mountainside covered in snow might appear as a uniform surface, it is actually made up of many layers of snow from different storms, each of which might have very different compositions. For example, a "dry" snow from a very cold storm might land directly on top of a sun-baked layer which turned to ice. The point at which these layers meet is called an interface, and is where slipping or sliding of one layer on top of another is most likely to occur. This occurrence is what can trigger an avalanche. Snow conditions on a slope can also evolve over time with wind and sun and other weather patterns, so even a once-safe slope might increase in risk under certain conditions. People recreating in the outdoors in the winter can benefit from learning about these situations from avalanche professionals.

What is the difference between coalesce and repartition when it comes to shuffle partitions in spark

Coalesce essentially groups multiple partitions into a larger partitions. So use coalesce when you want to reduce the number of partitions (and also tasks) without impacting sort order. Ex:- when you want to write-out a single CSV file output instead of multiple parts Use repartition when you want to cause a shuffle that changes the number of partitions. A common use-case for repartition is to remove skew in file sizes or to start out with a smaller/different number of partitions than the default in Spark

What makes for a great pizza?

There are many different variations of pizza. Many would say that the crust and sauce are more important than the toppings when considering what makes a pizza great.

Is Linux Unix?

Officially an operating system is not allowed to be called a Unix until it passes the Open Group's certification tests, and supports the necessary API's. Nobody has yet stepped forward to pay the large fees that certification involves, so we're not allowed to call it Unix. Certification really doesn't mean very much anyway. Very few of the commercial operating systems have passed the Open Group tests. Unofficially, Linux is very similar to the operating systems which are known as Unix, and for many purposes they are equivalent. Linux the kernel is an operating system kernel that behaves and performs similarly to the famous Unix operating system from AT&T Bell Labs. Linux is often called a "Unix-like" operating system. For more information, see http://www.unix-systems.org/what_is_unix.html.

Why should one travel the world?

As the son of a U.S. Diplomat, I've had the opportunity to live abroad most of my life in countries such as Cambodia, Australia, South Korea and Malaysia.

Is brazilian jiu jitsu good for self defense?

Brazilian Jiujitsu, or BJJ, is known as the gentle art in martial arts. BJJ can be practiced in two modalities: Sport BJJ and the other as self defense. Sport BJJ is competitive and based on a point system based on a competitor being awarded a number of points based on advancing to a more advantageous position. Alternatively, a competitor may immediately win the match by submission. When BJJ is used in self defense, the goal is usually to subdue an attacker. Since BJJ is mostly grappling from the ground, it can be a highly effective practice for self defense as many street fights end up on the ground. While many of the techniques are intended to immobilize an opponent, it can be less effective if the opponent has an unfair advantage such as the use of a weapon. Practicing BJJ routinely will prepare the practitioner mentally for physical combat which can be advantageous in a self defense scenario. Another reason BJJ can be viewed as good for self defense is that there are techniques that can work well for different body types that level the playing field for even smaller or weaker opponents. If both opponents are trained in BJJ, size and strength can become a larger factor. Routine training can also lead to increased physical fitness as classes can be quite rigorous and physically demanding. Some may argue that more ruthless martial arts are intentionally designed for self defense and therefore may be more effective.

How does the Harvard housing system work?

First-Year students live in one of the seventeen dormitories located in and around Harvard Yard. Rooms are assigned based on a brief survey sent to admitted students. The survey asks questions like “How many roommates do you want?”, “How comfortable are you with noise?”, and “What type of music do you listen to?”. After the first year, the majority of students move into one of the twelve residential Houses. Houses are assigned in March of a student’s first year. Rather than randomly assigning individual students to houses and scattering close friends, students can assemble into “blocking groups” of no greater than 8 students and each group is randomly assigned to a House. If 8 friends aren’t enough, two blocking groups can link themselves in the lottery. Linked groups will not be assigned the same House but are guaranteed to be assigned the same Neighborhood (e.g. The Quad).
