Summarize the following:
Children sometimes think of the internet as a "pretend" kind of place free of real-world consequences. You should correct these misunderstandings as soon as your children are old enough to get online. Mention the threat of cyber bullying, but in addition, make sure your children know that they should not communicate with strangers online or attempt to meet up with people they meet online. Discourage your children from placing their full names, addresses, or other identifying information on websites. These habits are important safety precautions in and of themselves, but they also help instill the notion that the virtual world and the physical world are connected, and that what they do online can have consequences offline. Children and teenagers sometimes fail to realize that any pictures they post online are no longer private; they lose control of who can see them and make themselves vulnerable to predators. Make sure your children realize that embarrassing pictures, sexy pictures, or any pictures that reveal their naked bodies should not be shared online. Tell your children that they should not share their passwords with anyone, including their closest friends. Sharing passwords removes one's ability to maintain control of what is posted from personal accounts Consider requiring your children to share their passwords with you, however, especially if they are still quite immature and/or they have shown themselves to be irresponsible about the online world. Having your child's passwords will allow you to monitor his or her online activities. Using the internet is, in many ways, just like interacting in the real world: your children need to be polite and consider other people's feelings. In particular, encourage your children to stop and think about what they want to say before posting something online. The perceived social distance that's involved in online activities can sometimes prompt children and teenagers to say things that they would never say to someone in person. Remind them that what they do on the internet is "real." Suggest that they refrain from sending messages when they are angry or upset. Tell your children that you want them to come to you if they run into problems online. If they are being cyber bullied, you want to know about it.

summary: Discuss the potential dangers of the virtual world with your children. Place limits on the information your children can put online. Explain the dangers of posting certain kinds of pictures online. Remind your children not to share their passwords. Instill the concept of netiquette as soon as your children begin using the internet. Encourage an open dialogue.

Use this method if you know: two different speeds; and that those speeds were used for the same distance. For example, if Ben drives the 160 miles to the waterpark at 40 mph, and returns the 160 miles home driving 60 mph, what is his average speed for the entire trip? The formula is s=2aba+b{\displaystyle s={
rac {2ab}{a+b}}}, where s{\displaystyle s} equals the average speed, a{\displaystyle a} equals the speed for the first half of the distance, and b{\displaystyle b} equals the speed for the second half of the distance. Often problems requiring this method will involve a question about a return trip. In these types of problems, it doesn't matter how far each speed is driven, as long as each speed is used for half the total distance. You can modify the formula if given three speeds for the same distance. For example, s=3abcab+bc+ca{\displaystyle s={
rac {3abc}{ab+bc+ca}}}. It doesn't matter which speed you substitute for a{\displaystyle a} and which you substitute for b{\displaystyle b}. For example, if the first speed is 40 mph, and the second speed is 60 mph, your formula will look like this: s=(2)(40)(60)40+60{\displaystyle s={
rac {(2)(40)(60)}{40+60}}}. This number should be the numerator of your fraction. For example:s=(2)(40)(60)40+60{\displaystyle s={
rac {(2)(40)(60)}{40+60}}}s=480040+60{\displaystyle s={
rac {4800}{40+60}}}. This number should be the denominator of your fraction. For example:s=480040+60{\displaystyle s={
rac {4800}{40+60}}}s=4800100{\displaystyle s={
rac {4800}{100}}}. This will give you the average speed for the entire trip. For example:s=4800100{\displaystyle s={
rac {4800}{100}}}s=48{\displaystyle s=48}. So, if Ben drives 40 mph for 160 miles to the waterpark, then 60 mph for the 160 miles home, his average speed for the trip is 48 mph.

summary: Assess what information is given. Set up the formula for average speed given two speeds used for the same distance. Plug the speeds into the formula. Multiply the product of the two speeds by 2. Add the two speeds together. Simplify the fraction.

Website that use lots of Flash or Java can take much longer to load. Try not to rely on these for your basic web page, and don't make Flash videos play automatically. This is an issue with sites which automatically play embedded (e.g., YouTube) videos as well. Large, high-quality images can slow down your website considerably, and may burn through your server hosting space as well. Many photo editors and website hosts alike offer an option to optimize your photos for web publishing, so take advantage of this option. Most website hosting services also offer an option to load images as viewers scroll down rather than loading a whole page's worth of images at once. While images are important when attempting to make your site more attractive, they can considerably slow down traffic from slower browsers and platforms. Don't overuse images. Minification removes all unnecessary characters from code, typically white space, new lines, and comments, which will both help your site load faster and boost your website's search engine optimization. Closure Compiler by Google can minify Javascript for free, while other free minimizers can be applied to different types of code (e.g., HTML). You will still be able to edit your code with the human-readable organization. The code is minified only when it is uploaded to the server. Make sure you are using the latest version of PHP so you can benefit from the latest improvements. While the PHP developers try to keep the language backwards-compatible, you will probably need to spend some time updating your code in accordance with the latest changes. If you're using a website hosting service such as WordPress or Weebly, you shouldn't have to worry about manually updating your website's PHP. Enabling this option for your webpages' files, photos, and other content will ensure that users who allow cached content won't have to retrieve the content every single time they revisit your site. Any users who clear their browser's cache and cookies before revisiting your site won't benefit from this, but the bulk of people who come across your site will be positively impacted.
summary: Reduce your use of intensive applications. Optimize your images. Minify CSS and Javascript code. Use the latest version of PHP. Make sure your website caches files locally.
