In one sentence, describe what the following article is about: The shell can be opened by using the following key combination: Control + ALT + F1. You can also open a Terminal that acts as a shell from your System Tools folder. All commands listed below can be entered at the command line in the Linux shell or Terminal. The following commands require root privileges, so you should be logging in using su (or sudo). Type in your login and password to log as root. Users of Debian Linux should type in the following command: "apt-get install unrar" or "apt-get install unrar-free". If you are using Fedora Core Linux, type in the following command: "yum install unrar". Arch Linux users should install from extra repository using "pacman -S unrar". Users of OpenBSD type in this command: "pkg_add v r unrar". Suse10 users can enter "yast2 i unrar". Suse11 users can enter "zipper install unrar". Type "cd /tmp". Type "wget http://www.rarlab.com/rar/rarlinux-3.9.1.tar.gz ". Unrar the file with the following command: "tar -zxvf rarlinux-3.9.1.tar.gz". Enter "cd rar". Type "./unrar". "cp rar unrar /usr/local/bin". The unrar command is now available for use in your Linux installation.
Summary: Make sure that your computer is connected to the Internet. Open up the Linux shell if you are currently in the Linux GUI. Use the right command to download unrar into your Linux installation. Download the binary package directly from rarlab if the above commands don't work. Locate the rar and unrar commands in the rar directory. Copy the rar and unrar to the /usr/local/bin directory with the following command:

In one sentence, describe what the following article is about: Select cell I 6 (the cell directly below the "Total" cell) Under the Formulas menu, select Auto Sum Click and drag cells D6 through H6 across the row. Press Enter To copy the formula to the entire Total column, Click and drag the fill handle until you reach cell I15. (this will copy the function to each row, calculating the total grades for each student) (in this example, we will assume the maximum total possible of the grades is 500) Select cell J6 (the cell directly below the "average" cell) Click on the Formula bar to type Type =16/500 Press Enter From cell J6, click and drag the fill handle to the entire average column, until cell J15 To format the average in a percentage form, select the column J6 to J15 Right click on the selected column Choose Format Cells, a dialog box will appear From the Number tab, click on the Percentage category Change the number of decimal places as you prefer Click Ok. To perform this function we will need a key, which is simply table of letter grades and corresponding numbers. We will use a sample table from Excel. Create The Key Table Select cell M7, we will start typing the table here Type "Average", this will be the first column Press the tab key Type "Grades" Under "Average" type your grading scale scores Under the "Grades" column, type the corresponding letter grade to each score The function required to return a letter grade is the VLOOKUP function, and is called a nested function. It follows the formula:VLOOKUPlookup_value,table_array,column_index_number,[range_lookup]) Select cell K6 Start typing the formula =VLOOKUP(J6,$M$18:$N$22,2,TRUE) Explanation: after the brackets, type the cell that contains the final score of the student which is in this example cell J6. The second part of the formula is automatically included by selecting the key table; press F4 from the keyboard to insert the dollar signs that will lock the range selected. The third part is the column number from the table that contains the letter grades. True stands for approximate match with the values of the column, false will result in exact matches. Press Enter Copy the formula down to the entire column until cell K15 by clicking and dragging the fill handle from cell K6. Repeating this process will allow you to calculate grades for other classes in the future.
Summary: The Total of The Students' Grades The average of the gradesTo find the average of the grades for each student, we will divide the total found in the "total" column by the maximum total possible. Translate The Calculated Average Grades to Final Letter GradesExcel allows us to add a function that automatically calculates a grade based their averages in column J. Type The Formula.

In one sentence, describe what the following article is about: You may want to comment to show your appreciation, or ask questions. The autistic community is an autistic place, but friendly visitors are always welcome. It is okay to share articles or retweet/reblog things you found in the #actuallyautistic tag. (You may wish to mention that you aren't autistic, though, so people don't get confused.) It's okay to say that an article helped you, or that you agree. It's okay to ask questions. However,autistic people are not search engines, so they are not obligated to provide an answer. Remember, there are plenty of allies who participate in discussions and write autism-related posts! While plenty of autistic people are happy to help, some questions ("Do autistic people have bellybuttons too?") seem a little obvious ordemeaning. If you have a question, search the internet for a few minutes first, because the answer might be readily available. Like all subcultures, the autistic community has some unwritten etiquette guidelines. Here some insider tips regarding things to avoid: Avoid posting in the #ActuallyAutistic tag if you aren't autistic. It was developed specifically for autistic people to discuss things, without non-autistics interrupting. Non-autistics can post in the #autism, #AskingAutistics, and #AskAnAutistic tags. Respect all autistic people. All autistics, regardless of ability, deserve dignity and respect. Your average autistic person wants respect for everyone, including people who are more capable than they are, and people who need more help than they do. Don't assume you understand someone else's struggles. Never dismiss someone as being "articulate" or "too high-functioning" to understand what "real autism" is like. You don't know what that person might go through on a daily basis, and they may face serious issues. Furthermore, even if their life is fairly good, that doesn't mean they aren't allowed to have opinions, or that they haven't listened to autistic people who have it worse. Remember not to take venting personally. Sometimes, autistics may talk about bad experiences they've had, and possibly make generalizations in the heat of the moment. Just like it's rude to say "Not all men!" or "Not all white people!" saying "Not all NTs" or "Not all therapists!" only derails the conversation and makes it about your feelings. If you don't do the bad thing they're talking about, then it's not about you. If you do the thing, then you can use this information to re-evaluate your behavior. Allies are welcome, and autistic people can always use a hand in organizing events, finding resources, or simply educating the community. If you see autistic people organizing something, feel free to ask "Can I help?" or "May I join you?" Some autistic writers have articles written specifically for how you can help your loved ones and be a great ally. Never be afraid to ask for tips! Feel free to check out other autism articles on wikiHow, like How to Relate to an Autistic Person and How to Understand Autism.
Summary:
Realize that it is okay to join most discussions. Use a search engine for basic questions. Be aware of general etiquette. Don't be afraid to help out! Look for resources written for non-autistic people.
