Problem: Write an article based on this summary: Type emacs filename.txt into Terminal. Press ↵ Enter. Get to know Emacs commands. Enter your document's text. Press Ctrl+X, then press S. Press Ctrl+X, then press Ctrl+C. Re-open your text file.

Answer: You'll replace "filename" with your preferred name for the text file. As long as your text file's name isn't a duplicate of an existing text file in your current directory, this command will open a new text file in the Emacs editor.  For example: a file named "newfile" would require you to type emacs newfile.txt. If you entered an existing text file name, this command will instead open the file in question. Emacs comes complete with tons of powerful commands that let you navigate around a document, look up related or help information, manipulate text, and understand your code. These commands fall into two types: Control commands and Meta commands.   Control commands are written like this: C-<letter>. To execute a Control command, you'll hold down the Ctrl key and press the specified letter key at the same time (e.g., Ctrl and A).  Meta (or Escape) commands are written like so: M-<letter> or ESC <letter>. The "M" refers to a computer's Alt key or Esc key, since not all computers have the Alt key. A command written like C-a b (or M-a b) will require you to hold Ctrl (or Alt or Esc) while pressing the first key (e.g., a, then release both keys and immediately press the second key (e.g., b). You can simply type as you typically would for any other text document. To save the current line of text and jump to the next line, you'll press ↵ Enter. Doing so will save your file. This will exit the Emacs text editor and return you to your directory in Terminal. Your text file should now be saved under your selected name in this directory. To do so, simply type emacs filename.txt into Terminal. As long as you're in the same directory as is the file, doing this will open your text file in Emacs, at which point you may resume editing it if you please.


Problem: Write an article based on this summary: Start planning while in high school. Choose a collegiate engineering program. Gain practical experience while in school. Complete your degree.

Answer: Take plenty of math and natural science courses while you are still in secondary education. Opt for advanced classes if your school offers them. If you don’t enjoy, or struggle to do well in high school courses in chemistry, biology, physics, algebra, trigonometry, and calculus, environmental engineering may not be the field for you. Enroll in an environmental, civil, mechanical, chemical, or general engineering degree program. A bachelor’s degree in engineering is the minimum requirement for environmental engineers.   Whenever possible, choose a program that is accredited by ABET (the Accreditation Board for Engineering and Technology).  This may be required for licensing in your state.  Some colleges offer combined BS/MS programs, which typically take five years to complete.  Obtaining a Master’s degree is not normally required, but may improve your career prospects. Significant hands-on, real-world experience is expected before any new environmental engineer begins his or her career.  Fortunately, environmental engineers have several options for gaining such experience while in school.  Find environmental engineering internships during your summer breaks. If your school doesn’t offer these internships, look at the Environmental Protection Agency, www.epa.gov/oha/careers/internships, or engineerjobs.com. Apply for an engineering co-op job your sophomore year in college. Many universities work with employers to offer students work experience as they complete an engineering degree. You must maintain a GPA of 2.7 or higher with many co-op programs. Get involved with a university research team. If you are unable to find an internship or co-op during a semester, apply to help with an environmental engineering research project. Experience in analyzing and testing data is highly valued in the workplace. Apply for an entry-level environmental engineer position. You can’t lead an engineering project in most states without a license. However, the experience gain assisting a licensed environmental engineer will help you to earn your license. Remember, without a BS degree in engineering from an accredited college or university (and also, preferably, one with ABET accreditation for its engineering program), you cannot become an environmental engineer. You could still consider a related career, such as Environmental Scientist / Specialist (which requires a BS degree), or Environmental Engineering Technician (which requires an Associate’s degree).


Problem: Write an article based on this summary: Do your research. Decide what is right for you. Know the risks. Think about the recovery process. Weigh the pros and cons.

Answer: It is possible that breast implants are a great option for you. The procedure can be very effective, and is often the choice that those recovering from breast cancer or other illnesses make. As with any surgery, make sure that you understand the procedure.  Find a doctor with a great reputation and schedule a consultation. Before your appointment, make a list of questions to ask. Read up on the procedure. If you know someone who has openly had breast augmentation, ask them if they would mind giving you some advice. Once you understand your options, think about which is right for you. Do you want silicon or saline implants? How large would you like your breasts to be? Ask yourself these questions, and make sure that you feel comfortable with your own answers. Envision the results and try to imagine how surgery would impact your life. Any medical procedure is bound to have risks. In addition to the general problems that can arise any time you are under anesthesia, make sure that you know the potential problems that can arise with breast implants.  For example, ask what will happen if they rupture. It is also important to ask about the possibility of infection and side-effects such as scar tissue. You should also consider whether or not you plan to (or want to try) breastfeeding at any point in the future. Some women are unable to breastfeed after surgery, so this is definitely something important you want to discuss with your doctor. Also, keep in mind that you will have to get the implants replaced about once every 10 years. Having surgery to increase your breast size is not a simple procedure. When doing your research, make sure to take into account the recovery process. You'll want to make sure you are prepared to take time off from work or school and many of your daily activities.  Talk to your friends and relatives to make sure that you will have a support system to help you out while you recover. You won't be able to lift things for a while--even a bag of groceries might be too much. Recovery is something to ask your doctor about. Make sure to have that talk before you commit to surgery. You are the only one who can decide if surgery is right for you. Make a list weighing the positives and the benefits of taking this step. Are you doing it for yourself, and not another person? Are you physically and emotionally ready to undergo an operation? Ask yourself these, and many other, questions. Don't rush yourself. Think carefully about taking this step and what you hope to gain.


Problem: Write an article based on this summary: Use a paper towel to blot the paint. Mix 1 quart/950mL water with 1 ounce/30mL dish detergent. Sponge away the remaining paint residue. Dry the faux leather with a soft cloth.

Answer:
As soon as you notice a wet paint stain on faux leather, grab a paper towel. Use the paper towel to absorb as much of the wet paint as possible. Try to avoid spreading the paint beyond the borders of the original stain.  You might need to use several paper towels to absorb all of the remaining paint. Make sure you blot instead of rubbing. Rubbing the paint will cause it to penetrate into the faux leather more quickly. In a bucket or large container, mix together 1 quart/950mL of hot water with 1 ounce/30mL of mild dish detergent. Combine the two ingredients to make a soapy cleaning solution. Dip a sponge into the mixture of hot water and mild dish detergent. Squeeze the excess water from the sponge, and then use the sponge to clean away any remaining residue from the paint. Rinse the sponge out in the cleaning solution when one side of the sponge becomes saturated with paint. You should rinse the sponge at least once during your cleaning session. Make sure the sponge is only damp with the solution, not soaking wet. Once you have successfully removed the remaining paint residue, dry the area completely. You can use a soft cloth, like cotton or microfiber, to dry the area. You can also use a paper towel to remove residual moisture.
