I would like to contribute to the blog too. A couple of topics that are within my reach are: Making the transition from MATLAB to Mathematica (series) — aimed at users who are repeatedly told and fed the myth that Mathematica is slower and only good for computing the 1000th digit of π (this comparison, which is a top hit for "MATLAB vs Mathematica" doesn't ...

I would like to write on something, but not yet sure on what :). Here are some topics which came to mind now: Mathematica evaluation sequence, tools of evaluation control, and some practical examples of their use. Advanced programming tools, such as higher-order functions, closures and macros, and how they help design modular programs. Scoping as a ...

I would suggest a series of posts on "obscure Mathematica function or option of the week". It could cover things like the level specifications in Join and Flatten, non-obvious uses of Inner and Outer, the finer points of UnitStep, Boole and DiracDelta etc, as well as some of the less well known functions, such as those in the model-fitting functionality. I ...

I could do a few posts as well. I was thinking of a post explaining how graphics work, the different types of units that Mathematica uses (plot coordinates, scaled coordinates, offset coordinates), and also discuss exporting publication quality graphics. (This is related to @R.M.'s second topic, it could be part of that series.) I'd like to do a post on ...

I would like to contribute too. There are a few answers of mine such as the word cloud one which I would like to elaborate and I think a blog would be a good place for that. I can't guarantee that my posts will be as insightful as Leonid's or Mr.Wizard's are indubitably going to be, but I can guarantee pretty pictures at least.

I would be interested in writing an article describing some terse coding methods and syntax tricks. I think a blog would be a good place to assemble and describe things like ##&[]. It could also be a good place to make the case for ~infix~ much to everyone's delight. ;^)

I think this is a very good idea. To add to this, a new user will also see the following banner above the list of questions. Here, "users of Mathematica" can also be changed to "users of Wolfram Mathematica". This banner is another example of where new users only see the word Mathematica, without further explanation or failsafes against thinking ...

bugs Do not add the bugs tag to your question until your observations have been confirmed by other users or Wolfram Technical Support. Related thread: How to report bugs?

I've enabled this for users with <= 200 reputation. ...That said, don't expect too much. This will correctly detect large code dumps, but won't necessarily detect single-line expressions interspersed with prose as in your example. I've also enabled a check that enforces a code to non-code ratio (currently 4 characters non-code to each line of ...

This is a proof-of-concept using Pastebin. It's a utility function that you can put in your init.m to always have available in case you need to upload a list (or another string). How to install it Create a user account at Pastebin.com. Log in and copy your dev key from this page. Go to this page and generate a user key. Modify the function below with your ...

windows Only use the windows tag if you have evidence to believe that your question is related to this specific OS. Do NOT use it to simply indicate the OS you are currently using. You could provide that information in the body of your question. osx Only use the osx tag if you have evidence to believe that your question is related to this ...

Lest we forget, there is also a built-in way in V10 to share expressions with other users, namely CloudPut with Permissions -> "Public" and CloudGet:

I support this feature request, because I feel especially a copy to clipboard button would be very nice. However, I have some concerns with respect to request "Additionally I would like a button for uploading a text-based file such as a Notebook". My concerns I am against sharing "raw" (unconverted, including a lot of Box expressions) notebook files on the ...

I think there are three topics where I both feel confident enough and have the code almost ready at hand to contribute to the blog: Building graphical user interfaces: how to create new controllers, how to put together a fully-fledged GUI. Recently I had to design a lot of these things, and during this excursion I've learnt a lot that might be useful for ...

You (and all people involved) have done a great job; thanks a lot for that. With a few minor changes, I'm very happy to include it, and will do so shortly have done so. A few notes though: We will not include it on Stack Overflow, only here on mathematica.se. There are several reasons for this. Most Mathematica activity has moved over from SO to this site (...

Reading the commentary here, it kinda sounds like this might be a good idea across the board - that is, to change "Mathematica" to "Wolfram Mathematica" everywhere the site topic is used. This includes the sidebar, the prompt (grey text that appears in the title entry before a title is entered), and various other places (default close reasons, the help ...

This has been enabled. Enjoy. (:

One idea I had last night for a series was to have various people write about what's in their tool bag and how they customize their Mathematica environment. Our local newspaper has a few regular features like this, such as Studio Visit (arts & entertainment) and Gearhead of the Week (vintage automobiles). Potentially this is something that a lot of ...

There are several entries I'd like to make as time permits: Begin and BeginPackage versus c++ namespaces. Their behaviors can be surprising. and others as they occur to me. Or, more correctly, as I think I have something complete enough to discuss.

Yes. Wolfram Technical Support is where you should send suggestions for Mathematica. When you make a suggestion, it's important to make sure you are clear that you are making a suggestion and not requesting technical help. I would suggest even beginning the email with "I have a suggestion for Mathematica..." Sometimes people are unclear about what they ...

I often send send suggestions for what I think would be improvements to Wolfram tech support. I try hard to make these suggestions clear, complete and well-focused. This is important, because I am sure receiving vague and rambling suggestions must very frustrating for tech support personnel and a waste of their time. I have always received replies to my ...

Done, this will be live after the next build (later today). Thank you for your continued work on this!

No, feature requests are off-topic here or on the main site. They wouldn't make much sense either, because this site is community driven and no official channel to communicate with Wolfram Research. As already said in the comments, the official Wolfram Community or the Wolfram Support is the correct way for such requests.

In the upper left corner, next to the recent achievements and the inbox there is a link list to all StackExchange sites.

version-6 Do NOT use the version-6 tag in bug reporting. If you are posting about apparent bugs, provide the Mathematica version(s) in which you are seeing your issues in the body of your question and when more information becomes available use or update the header as described in this Meta post. version-7 Do NOT use the version-7 tag in bug ...

The prettyprint process, that is used on the main site, chances the appearance of a_ to its italic version a_. The Consolas part of the default font-family for code makes a and α look very similar. The default text font-family, Arial, isn't suitable for code. Here are two alternatives I have tested by changing the code style with the developer tools of the ...

Note: Heavily updated I'm in charge of this. For the new version 12, I used last weekend to completely restructure the code and move it to a new repository: Wolfram Language support for the Google Code Prettify I spend a good amount of time to document how it works and to prepare examples and tests. The final highlighter script is either lang-mma.min.js ...

While I understand why you're requesting this feature, I disagree with the request. Your block should either be understood as code or math, but it can't be both at the same time without confusing a good number of users. As a counter point to your example, consider: With[{x$a = 1, y$b = 2}, {x$a, y$b}] That is valid Mathematica syntax. Now you wouldn't want ...

While I totally support the idea, I have very strong doubts this would ever be possible on SE. Just put yourself in place of SE developers / management: if I were one of them, here are some things that would be a complete no-go: Security: since this is based on a plugin, this can affect the client computer in a variety of ways, and SE has no control over it,...
