Winter 2013 - January to April 2013 - Updated 2019-02-11 14:45 EST
Learning how to ask good questions is a skill you need to learn if you want to get help from other people.
If you have been sent to read this document, it is likely because your questions are too vague for me to answer.
If you follow the advice in this document, I’ll be able to help you more quickly, and you’ll get better answers from other people.
When you ask a question, the quality of the answer you get depends largely on how detailed and specific you are in your question.
I can’t help with or answer a vague question such as “I can’t log in - do you know why?”, or “Why do I get a time-out?” or “I can’t do question 3” any more than a mechanic can answer a question “My car won’t start – do you know why?”. You must be precise in your question, giving me as much information as you can about your situation.
Things you might consider telling me when you ask a question:
Which assignment question are you trying to answer?
What have you tried already? What, exactly, did you enter into the shell or into the program? That includes exact keystrokes, names, addresses, configuration settings, etc. Tell me what exactly you used, not what you think you used; send me a copy of your command line or of your configuration settings. Tell me what your current directory was.
Saying “I entered the information from the notes” is not helpful, since perhaps the notes are wrong, or perhaps you typed it wrong. What exactly did you type? What defaults are set in the program already?
What messages did the program(s) already give you? That includes the exact text of the messages, not what you “think” it said. Copy the exact text of what the program said into your question to me.
If it’s a network issue, then:
What have you read to help solve your problem? Before you contact me, I expect you to read the lecture notes you took in class, the assignment (all the words!), and any posted class notes related to the problem.
If you use multiple machines, what machine and operating system are you using? Ubuntu Linux 12.04 on a Dell laptop? Windows XP on a home- built desktop machine?
What program(s) are you using? Command-line FTP? PuTTY version 0,60? Firefox 9.0? DOS window FTP? What version?
For most questions, my job as instructor is to help you find the answer, not to give you the answer. Specific answers will change and become irrelevant over time, but knowing how to find an answer is always useful. You’ve already paid me, as a College instructor, to help you find answers.
If you want me to actually give you the answers, that’s called “private consulting” and the rates are much higher – contact me after you graduate.
You will get better at finding your own answers as you know more and become more familiar with search tools and asking the right questions.
The first step is to realize that learning to find answers is a skill you can, and must, learn.
Many questions are not new; other people have already asked them, and I’ve already incorporated the answers into the assignments and the course notes. Before you ask a question, make sure I haven’t already answered it.
Learn to search the assignments and course notes for your answers. You can use the page-search features of web browsers to look for keywords in web pages, you can search for keywords in word-processor documents, and you can use grep
at the Unix/Linux command line to search many text or HTML files at once. (The -i
and -r
options to grep
are useful.)
Searching the assignment or the course notes is very efficient. You might be able to use Google to find your own answer on the Internet, but often Google hasn’t indexed my course notes yet so the specific information you need won’t be on the Internet yet. You will also find it harder to see the specific information that I give you among the billions of web pages that Google will suggest to you for answers.
I usually ask questions based on material in the assignments and course notes. Check the assignments and course notes for answers, first.
For a slightly abusive but very thorough explanation of how to ask “smart” questions and get good answers from busy people on the Internet, read the classic document “How To Ask Questions The Smart Way” by Eric S. Raymond and Rick Moen: http://www.catb.org/~esr/faqs/smart-questions.html
As their document says: They are not a help desk. Do not send them questions!
Here are some actual vague questions that have been sent to me that I would like to answer but cannot because the poser didn’t supply me with enough specific information to help (e.g. what exactly they did):

I am trying to upload the assignment; however, filezilla will not connect. I know that all info I put into the program is correct, because I logged off ot the CLS and re login and it connected.

You don’t say what host name you are trying to connect to. You don’t give anyone enough information to help you with your problem.]
“I am trying to access the server offline.but it is showing the error that host does not exist.please help me with this” [There is no such thing as an “offline” server in this course. (If a server is offline, then by definition you can’t access it.) You don’t say what server name you are trying. You don’t say whether you are on campus or off campus. You don’t give anyone enough information to help you with your problem.]
“I am unable to open putty on my computer. It is showing time out on putty server. I need to complete my linux assignment but due to the issue with putty I am unable to work on that.

You don’t say where you are located or what your IP address is. You don’t say what network you are using. You don’t show what host name you are trying to connect to.]
“My putty is not working. I click on on-campus it is only showing the blank screen. It doesn’t work. Please help me.” [You don’t say where you are located or what your IP address is.

Whenever I try to open the putty, I only get one message”Network error, Connection timed out”. Please, would u help me now to solve this problem?” [You don’t say anything about what address you are trying to connect to. Your use of “u” instead of “you” is unprofessional.]

“I get the error : curl: (7) couldn't connect to host
.” [You didn’t tell me anything about what commands you actually typed to generate that error. You haven’t told me about any network diagnostics you did to see why you couldn’t connect. Maybe you spelled the host name wrong, but you didn’t tell me what it was in your EMail, so I can’t tell.]
“I am getting a permission denied message when I try to run or change my ‘check’ symbolic link file that I created at the beginning if assignment08.
