This is a quick tutorial to teach you how to use Wolfram Community in almost no time. Just a few minutes of reading through this will save you a lot of time and make your posts clear and beautiful. Please be kind and give back to Community by following these simple rules:
Read Wolfram Community Guidelines.
This forum is about Wolfram Technologies. Demonstrating relevance of your posts to Wolfram Technologies, especially in the form of Wolfram Language code, is essential. For other subjects, including general science, post elsewhere.
Excessive posts advocating or suggesting the use of a competitor's product are inappropriate, and we reserve the right to edit/delete such posts/threads at our discretion.
Be gracious to others. Vote up good posts.
Do not bluntly solicit for help. Do basic research on the subject before asking the question using free documentation and basic web search that would lead to many other sources available freely online. For programming questions, first show your own effort and solution in form of the Wolfram Language code.
Use your real name in Wolfram Community profile. Fill out your profiles in detail. It helps a lot to make friendly conversations and put your discussions in the right setting of your professional background. We run a clean professional network that will help your work and career.
Post and provide help in the area of your expertise.
Pose your discussions and questions clearly. Provide as much details as you can, including complete code you have issues with and any data if necessary. Do NOT send readers to another web-pages and forums if you can include information in your post.
Do NOT use external file storages such as DropBox etc. if you can attach file to the post.
Do NOT post code as images - other members need to evaluate code to help you. It is impossible to copy code from an image. Read this tutorial to learn how to post code properly.
Do NOT make generic titles such as "Help with a problem" and so on. Make titles clear and unique to your specific issue.
Check by searching first whether your question was already asked.
Check Documentation for examples relevant to your issue.
Do NOT use excessive CAPITAL letters in titles in posts.
Please do NOT use word "BUG" in titles unless it is confirmed. If you are sure you found a bug please report via regular channels. This also includes questions about Wolfram|Alpha step-by-step solutions. This forum is not the right channel for this. Also use feedback form down any Wolfram|Alpha page to report Wolfram|Alpha issues.
Remember, your time and opinion are not more important than others.
Wolfram Community provides the following essential features that we will overview:
Lightweight crystal clear post editor empowering you to post on the fly
Wolfram Language code formatting for easy copy-paste between Community and notebooks and lively syntax highlighting.
Images insertion anywhere in the post from the web or your computer, by drag and drop or browsing to a file.
Full mathematical notation for advanced formulas
File attachments for any format you can find in Wolfram Language Documentation
Now lets take a look at these in a bit of more detail.
Search
Currently Wolfram Community search is under construction. We strongly recommend using regular web search that will give you excellent results due to advanced SEO that Wolfram Community provides. A simple example of web search for keywords "network data" consists of the following.
This search will bring numerous well sorted resuts and also works with member names and profiles. The syntax works with most of other leading web search engines.
Post Editor
Wolfram Community Editor uses Markdown Syntax with full documentation available here. While you typing your post help is always available at the top right corner. Editor has a clear simple but yet powerful and flexible functionality outlined on the diagram below:
The Editor consists of two parts: edit area and preview area. While you use plain text markup syntax described in the documentation the preview are shows you exactly how post will appear after you publish it.
Code Formatting
Proper code formatting is an essential part of posting. Only then other member will be able to understand, copy and paste code between Community and notebooks. If a new line has 4 space at the beginning it is formatted as code.
- Type code in the editor or simply paste it from for example Mathematica
- Select all code
- Press CMD+K on Mac or CTRL+K on Windows
- Alternatively press code button shown on the very first diagram
- You can also use TAB key
This is how a properly formatted code block should look like - note beautiful syntax highlighting:
info = WolframAlpha["weather", "PodInformation"];
ids = Rest[DeleteDuplicates[#[[1, 1, 1]] & /@ info]];
titles = Map[{{#, 0}, "Title"} &, ids] /. info;
contents = Column[Cases[info, _[{{#, _}, "Content"}, val_] :> val]] & /@ ids;
MenuView[Thread[titles -> contents], ImageSize -> Automatic]
Images insertion
To insert an image anywhere in the text press image button indicated on the main diagram above. Follow simple instructions. You have a choice to
- Point to an image online by copying and pasting its URL in to the image up-loader form
- Browse to an image on your computer
- Drag and drop image from your computer
Please use only allowed image formats: .JPG, .PNG, .SVG, and .GIF. Images above 10MB will not be accepted. Files in format .GIF can be animated and we encourage their usage because they make your post very lively. Use the following tools for animated GIFs:
Mathematical Notation
Mathematical notation is enabled via MathJax. A very good tutorial can be found here: MathJax basic tutorial and quick reference. For Wolfram Language user it will be very easy to produce math formulas using built-in function TeXForm. For example code
TeXForm[Integrate[1/(1 - x^3), x]]
will produce output:
\frac{1}{6} \log \left(x^2+x+1\right)-\frac{1}{3} \log (1-x)+\frac{\tan^{-1}\left(\frac{2 x+1}{\sqrt{3}}\right)}{\sqrt{3}}
which when placed between $...$
(in-line) or $$...$$
(centered paragraph) will produce the following:
$$\frac{1}{6} \log \left(x^2+x+1\right)-\frac{1}{3} \log (1-x)+\frac{\tan^{-1}\left(\frac{2 x+1}{\sqrt{3}}\right)}{\sqrt{3}}$$
If you would like retain the original unevaluated expressions please use:
TeXForm[HoldForm[Integrate[1/(1 - x^3), x]]]
which when placed between $...$
(in-line) or $$...$$
(centered paragraph) will produce the following:
$$\int \frac{1}{1-x^3} \, dx$$
File Attachments
Files up to 10MB of any type found in Wolfram Language documentation can be attached to a post via the button at the bottom left corner of the Editor. Please attach only meaningful files - for example well structured and clear Mathematica notebooks or data. If images are not large it is better NOT use file attachments but insert images right in the text where appropriate to illustrate better the post content.
