  4. Founded in 2008, Stack Overflow’s public platform is used
    by nearly everyone who codes to learn, share their
    knowledge, collaborate, and build their careers.
    WHAT IS STACKOVERFLOW?
    “Helping developers and
    technologists write the script of the
    future.”

  5. ASKING QUESTIONS !
    “At Stack Exchange, we insist that people who ask questions put some effort into their question, and we're
    kind of jerks about it. That is, when you set out to ask a question, you should …
    o Describe what's happening in sufficient detail that we can follow along. Provide the
    necessary background for us to understand what's going on, even if we aren't experts
    in your particular area.
    o Tell us why you need to know the answer. What led you here? Is it idle curiosity or is
    this somehow blocking you on a project? We don't need your whole life story, just give
    us some context here.
    o Share your research on your problem; what have you found so far? Why didn't it work?
    And if you didn't do any research … should you even be asking? If you're inviting us to
    spend our valuable time helping you, it's only fair that you put in a reasonable amount
    of your valuable time into crafting a decent question. Help us help you!”

  6. Ask a question on Stack Overflow when you have
    a problem, not when you need help. "Help"
    means that you need someone to guide you
    through something, what you might get out of a
    book or a well-written tutorial. When you need to
    engage in a dialog with someone about the
    matter before you can understand it.
    Stack Overflow is ultimately for problems, not for
    getting "help" in this regard. Ask us a question
    when you have an actual problem in your source
    code. As a beginner, you're inclined towards
    needing help a lot more than problems. Ask when
    you have actual code that isn't working, not when
    you need to "get started".

  7. LET’S BREAKE IT DOWN
    Step 1: If applicable, research any core documentation + tutorials
    associated with your problem.
    Step 2: Research your question on Stack Overflow (questions, answers, and
    comments if you can).
    Step 3: If no results return from step 2, do enough extra research to
    formulate a specific, well-written, on-topic, and objective question.
    Step 4: Ask.
    If you have a question about , ask on

  8. ALSO KEEP AN EYE OUT FOR
    FOLLOWING..
    Don’t ask already answered questions (duplicate questions) - the fundamental goal
    of closing duplicate questions is to help people find the right answer by getting all of
    those answers in one place.
    If your question is not related to computer programming, don’t ask it on stack-
    overflow, go to that specific site - each community decides which specific topics
    are and are not allowed on their site.
    Don’t ask opinion based or broad questions: this question is likely to be answered
    with opinions rather than facts and citations. It should be updated so it will lead to
    fact-based answers.

  9. WHAT IF I DON’T FOLLOW THOSE GUIDELINES?
    Questions that need additional
    work or that are not a good fit
    for this site may be closed by
    experienced community
    members. Closed questions
    cannot be answered, but can
    be edited to make them
    eligible for reopening. If your
    question is closed, you will
    receive private feedback on
    the reason why it was closed.

  10. SO WHAT IS REPUTATION?
    Reputation is a rough measurement of how
    much the community trusts you; it is earned
    by convincing your peers that you know what
    you’re talking about. The more reputation you
    earn, the more privileges you gain and the
    more tools you'll have access to on the site -
    at the highest privilege levels, you'll have
    access to many of the same tools available to
    the site moderators.

  11. Reputation is entirely optional
    The three most important activities on Stack Overflow are Asking, Answering and Editing -
    none of which require any reputation at all!

    out/ your research on the
    question…
    ..and what you want as output.

  17. ASK DESCRIPTIVE QUESTIONS
    Provide a good description, don’t
    just post code samples, provide
    background/ steps to reproduce if
    applicable.
    • Tables
    • Proper formatting
    • Runnable code sample (both
    for Q/A)
    • Use tags properly

  18. DIFFERENT QUESTIONS > ONE ANSWER
    Do this when you come across two questions
    that looks different but you think the same
    answer can solve both issues.
    Do this only if the two questions are not
    duplicates. [Example duplicate question]
    Q
    Q A

  19. DIFFERENT ANSWERS > ONE QUESTION
    Q
    A A
    Most common case, a single question can have
    multiple answers in different environments/
    different contexts..
    Sometimes there can be different ways to do
    the same thing in the same environment as
    well.

  20. OPPOSITE QUESTIONS
    Sometimes you might have a question which is the opposite of an existing question,
    If that is the case you can link the existing question and ask your question.

  21. OLD QUESTIONS > NEW ANSWERS
    Due to change of versions/ new updates/ changing
    technologies, there could be new answers to old
    questions.

    View full-size slide

  22. FEW MORE THINGS..
    ✓ Use proper formatting (code): clean questions/ answers are always easy to read
    and understand.
    ✓ Start with your specialty: be an expert in one area, so you have a good
    understanding on how to ask/ answer
    ✓ Watch tags: keep an eye out for tags
    ✓ Have few example projects ready to go on your PC.
    ✓ Use JSFiddle/ .NetFiddle/ Google Colab like online compilers/platforms for
    demos
    ✓ Provide links where versions/documentations are important
    ✓ Give detailed explanations when answering without just posting code

  23. At the end of the day,
    your end goal should be to help others and
    build a better community,
    not reputation.
    It could either be one of your batch mates, one of your team member, a
    friend or a stranger, help everybody as best as you can, without
    expecting anything in return,
    not only on StackOverflow, in real life as well,
    and you will be rewarded for sure.
