This topic (which was not started by Mathworks) is for features you would like to see for this MATLAB Answers facility.

I suggest one wish per answer, so that people can vote for individual wishes.

I like Daniel's Idea about leaving this alone and starting a wish-list 2.0. I can't even load this whole page without IE8 dumping. Thus any new wishes from today I can't see. Here's my first:

-Once you hit a reputation of say 20, get rid of the "how to post an answer" comments that take up space.

Walter Roberson
on 28 Jun 2012

I have been thinking myself that we should start a volume 2. I would not delete anything here, though.

Ideally some of what is here should be moved to the new list. I did not want to just go ahead and create the new Answers, though, as that would not give proper credit to the people who originally proposed them.

Answer by Walter Roberson

  • In the list of questions, each question should have a "last updated" date and time, where an update is the addition of an answer or a comment or the editing of any part of it.

One can get the list sorted by most recent update time, but without a time stamp, one has to look at the individual questions all through to determine whether there has been an update since the last time one looked at it.

Answer by Matt Tearle

Include questions you've commented on (but not necessarily "answered") in "my answers". This way you can keep an eye on a question where you're asking for clarification or suchlike discussion.

Note: this would be rendered less important if we had notifications of some kind.

Hah. Makes sense. I ripped off that line from somewhere -- it was describing university politics... I can completely see how the stuff I observed at universities was an affluent society's update to our primal urges to have our political enemies ax-murdered by corrupt government goons (after which you take their mud hut, beads, and lion skin loincloths).


Answer by Matt Fig
on 2 Mar 2011

Answer folding.

Say there is a question which has 55 some-odd answers. I keep coming back to look and see if there is anything new, but since the answers move up and down with votes and other mechanisms, it soon gets exhausting. If I had the ability to fold answers I have read before - a choice that would stick between logins - then this process would be much easier.

I would like to be able to fold and unfold answers within a question. Perhaps a little star would appear next to the unfold button if there were new comments since I folded the question.

Jan Simon

A very important improvement! It is nearly impossible to find the new answer or comment in a set of 55 answers and 100 comments. It seems like even a comment, which is deleted directly after the creation, changes the oder of the answers. Then it is even absolutely impossible to find the modifications...

You're right. I'm not sure why I didn't see it at first. Maybe there are too many non-tutorial answers tagged as tutorial when they shouldn't be because they're just regular answers saying how to do something specific, such as this one: http://www.mathworks.com/matlabcentral/answers/19062-fprintf-table or unanswered requests for a tutorial, such as this one http://www.mathworks.com/matlabcentral/answers/32107-manage-oceanoptics. I might untag some and get rid of the clutter so that only real tutorials are in there.

Answer by Walter Roberson

Andrew mentioned as part of a previous suggestion that My Answers should include a search box. The same should also hold true when viewing someone's profile.

Go to my Answers and try to find something specific in there. With over 700 Answers logged already, good luck in finding what you are looking for...

The situation would not be as bad if the existing search box supported a tag for author search (and if author names were unique.)

And store the images on a MathWorks server. The other hosters will delete the images in the near or far future and then the corresponding question will become meaningless.


Answer by Jiro Doke

A way to automatically scroll to the most recent answer/comment/edit. For example, this question has many, many answers and comments. But I don't know where the most recent stuff is. Perhaps there should be a "go to next recent content" button on the page, that takes me to different sections.

This is a regression--we will change it back to votes-first soon.

Walter Roberson

Ah, I notice that the recent activity information at the top of the Question display, is now a direct link to that activity. That helps for the very most recent change, but not so much if multiple changes have been made.

Randy Souza
on 28 Jun 2012

The sorting regression is fixed--answers should now display with the accepted answer first, then the remaining answers sorted by number of votes (high-to-low) then date/time asked (least-to-most recent)


Answer by Andrew Newell
on 16 Mar 2011

Walter mentioned a "Best of Answers" area. A more flexible alternative would be an "Add to my favorites" button, so we can each keep a list of answers that we find really useful.

Of course, we can always bookmark them in our browser, but it would be good to keep them in the same environment as our personal questions and answers.

Walter Roberson

That's an interesting idea, Andrew.

Walter Roberson

Though the Best of Answers would be aimed more at the incoming people who are willing to do *some* searching but would get lost in the unstructured morass that exists now.

I get lost in the morass too. Recently I spent fifteen minutes trying to find a particular answer and gave up.

When one is being shown a list of Questions, it would be nice if hovering over a question link would show you a brief summary (e.g., first 100-ish characters) of the question statement. This would make it faster for people to take a quick look to see whether the question was interesting, or a quick reminder of exactly which question it was.

Still on my wish-list! Was wanting this again about 2 days ago...


Answer by Oleg Komarov
on 12 Feb 2011
  1. More meta info about the contributors: num. of votes given, num. of comments...
  2. Keep the meta info separate from answers/questions: try to load Walter's profile...it takes already a lot of time and if he keeps at this rythm in a year it won't be possible to load it at all...

I'm trying to think of long run stable way to query the site to have a score of the contributors. You can see an attempt in User reputation: post here to get into the list. It already takes 6 minutes to retrieve that info.

In general, it would be nicer if the list of the contributors and the meta info was available at one shot (and basically this is what I'm trying to reproduce)

EDIT

TMW team implemented a page with the metascores: http://www.mathworks.com/matlabcentral/answers/contributors

Please refer to it and congrats to the team!

Answer by Walter Roberson

Somewhere or other in the documentation, we need a note saying plainly that when a Title is edited, the effect is to create a URL which aliases the old one. For example, I had

 http:.../4321-j-random-title

and after I renamed it, that continued to be valid in addition to the new name

http:.../4321-john-q-title

This behavior of keeping the old name accessible can be important because URLs may have been created linking to the old name. This is a good feature; documenting it would save people like me from having to worry about such things.

  2 Comments

Walter Roberson
on 19 May 2011

Interesting... the behavior is not quite what I thought it was. It is not that aliases are created, but rather that as long as the number and dash are there, followed by any non-meta character (e.g., excluding '?'), then the match will be found. In the above example, http:.../4321-* would work just as well.

This is, incidentally, a way to link to a question by number without having to remember or copy/paste the entire title.

Randy Souza
on 28 Jun 2012

Technically, the dash is not needed either. So, for example, you can get to this question via:

Some way to prevent questions being deleted without a good reason!

I'm getting really annoyed with people whose response to your help is to disappear and take with them both their question and your response to it. It's happened more than once to me, and not necessarily questions where the poster was doing something dumb -- perfectly normal question, valid answer(s), then... floop! It's gone.

What really upsets me about a question that I have answered being deleted is I never can remember who asked the question. My feeling is if you are going to delete a question that I have answered, then I am not going to answer any of your other questions (at least until I think you have learned better).

Randy Souza
on 28 Jun 2012

We implemented a partial constraint on this behavior in a release on June 27, 2012. You can no longer delete your own question once someone has answered it.

Answer by Paulo Silva
on 18 Jul 2011

I would like to have a way to see when someone's account was created and how many questions that person deleted (maybe even the names of the questions deleted for those who are editors), this is because I clearly remember having answered several questions from someone but all those questions were deleted and the very same person posted a new question yesterday, I replied and that person exhibited the same old behaviour that triggered my memory, he/she didn't even look at the links I provided and asked something that isn't MATLAB related, I didn't answer the specific question because I would waste my time, this is MATLAB Answers not Control Engineering Answers.

Or at least answered by someone else. If you want to delete a question you answered yourself, I don't really see an issue.

Walter Roberson
on 19 Jul 2011

Although it is true that in theory this forum is about MATLAB, I find that in practice there are a lot of more questions about theory posed, or questions about theory that are disguised as MATLAB questions.

A fair bit of the time, "How do I do {something} in MATLAB" really means "I barely know what {something} is, but I have to implement it in MATLAB: how do I do that, preferably without ever having to learn anything about what the {something} really means or the mathematics behind it?"

I do admit that is the cynical view from having dealt with large number of students; I _do_ see people (including some of the students) who are interested in their topic, but are lacking the background in it and are also perhaps weak on their research skills (or research initiative) to investigate before trying to implement.

Randy Souza

We implemented "no delete if already answered" in a release on June 27, 2012. Click on the "Link" button next to an answer or above a comment.

Here's a blog post describing the major changes.


Answer by Oliver Woodford
on 20 Jul 2011

Many questions get asked again and again. Why? Because people are not searching for previous answers before asking questions.

Stackoverflow suggests some similar questions that have already been asked when people are typing in their questions. It's therefore easy for them to see that the questions already exist.

This system also relies on good questions being voted up, so they appear at the top of the list. I have asked several (dare I say) well-worded questions (and usually answered them well too), with a view to providing a resource for people to refer to. This effort is wasted by the questions and answers receiving no votes, and the fact that people never search for them anyway.

So, TMW please implement question suggestions like Stackoverflow, and regular users please vote for well-worded questions.

This would be a great advantage. I've never worked with Simulink, so it is more efficient not to read Simulink questions.

Walter Roberson

Looks like this has been at least partly implemented.


Answer by George Evers
on 15 Feb 2011

I like the idea of checking for relevant answers before posting a new question. As mentioned at [1], neural nets would be one vehicle for accomplishing this; alternatively, consider the following routine, for which x and y could be optimized.

Maintain a database of URL's, keywords, and tags for existing articles, threads, and questions.
For each new question title proposed:
* Define X as the set of all words of length > x from the user's proposed title.
* Search the database for articles/threads/questions whose keywords and tags match y% of the members of X.
* Display "Do any of the following answer your question?"
* Display best matches.

Implementing a quality search procedure now could prevent unnecessary clutter and avoid the difficulty of deciding whose answers to delete should cleanup otherwise potentially become necessary. This would help answerers by politely encouraging common sense questioning practices with which to prevent redundant and unnecessary questions, and users would feel more intelligently assisted and locate answers more quickly.

The dual objectives would be time-efficient search and high-quality user feedback. Search time might be reduced by categorizing questions and searching only within relevant categories. And recommendation quality could be optimized by using a modern optimizer to maximize the recommendation success rate per 100 questions on the 2D search space defined by x and y [2].

George, I like this idea a lot. This happens quite a bit in CSSM where people *may* search for things, but ultimately end up posting his/her own question (which happens to be the same as 10 other questions). I think the interface can be changed to encourage the "search first" behavior.

Right now, there is a Search bar where you can type in keywords. There's also a separate "Ask a Question" button. The first problem is that some people will always go straight to "Ask a Question". Having two separate interfaces (search and ask) gives the user options, and it becomes hard to enforce the behavior.

Now once a user asks a question, we could do something that you suggest which is to give some recommendations on existing questions. But we run into the issue that Walter mentions, which is that some people don't provide meaningful titles. Some titles have nothing to do with what they actually ask.

So what I think is that they should get rid of the "Ask a Question" button. There should only be an edit window that says "What is your question?". With that wording (as opposed to "Search MATLAB Answers"), people would hopefully ask the question using natural spoken grammar. They certainly won't type "help!" or "Plz give me code!" because that's not a question. It would force users to type descriptive questions. Based on that question, the system can go through and search the Answers database to come up with some candidates that may be relevant to the asked question. This part is the same as your idea. If the user doesn't see anything relevant, then he/she can go ahead and fill in the rest of the question (description, tags, products).

Andrew Newell
on 19 Feb 2011

Walter's experience with tags is exactly why I think that it would be better to just use Google for searching MATLAB Answers (see my separate answer). Why try to reinvent the wheel when someone else does it so much better? This would be quite consistent with many of the other proposals in this discussion.

Answer by Jan Simon

I do not like to be tracked by Google-Analytics. In Germany it is currently checked, if this service conflictes with the laws for data protection.

It is obvious that participating in a newsgroup is not very private at all. Nevertheless I see no reason to let Google know my IP, such that they can check if I've opened a browser window for Ebay or Amazon, while I'm posting at MATLAB Answers. Or does anyone needs informations like this: "People who have bought this book have been interested in these questions also: ..."

So my wish is: Disable tracking by Google-Analytics.

With Firefox and the Abine and NoScript extensions, I have enough control to disable cookies on a site by site basis.

On the other hand, unless I change my username, there isn't much that can be done about the fact that google is going to index the 'Walter Roberson' author against the content I write -- not without disallowing google from indexing the site, which would have many disadvantages.

Jan Simon
on 25 Feb 2011

Google-Analytics is an online service, which stores your IP-address. This is another quality than indexing the text you've posted here. If you browse through Ebay or other web sites controlled by GA, Google has enough information to perform the cross-correlations. If you browse this page from your IPhone with enabled IPv6 and did not enable the privacy control, Google knows even your unique MAC address.
I'm using NoScript also - otherwise it is hard to register that GA scans the users of MATLAB Answers.


Answer by Walter Roberson
on 15 Feb 2011

Documentation (and on-line help) of the search capabilities.

Known but not documented:

  • string to be searched for in the body
  • tag:"tag string"
  • product:"product string"

Thought I saw:

  • a prefix for searching by author. I can't reproduce this, not through author:"author name", not through author:contributornumber

Possibly it was in the newsgroup that I saw this supported.

Unknown and not documented:

  • any other supported prefixes
  • whether terms are phrases or "and" or "or", or if words not found at all are silently dropped and a search done on the rest.
  • whether terms are case sensitive -- or can be made to be
  • whether there is a spelling-correction pre-pass on the search
  • whether comments are searched
  • whether the search is on the unrendered or rendered form -- in particular, are urls themselves searched for matches

Search term stemming is used! For example if you search on "computability" you will find "computes" and "computing". Common suffixes are stripped off of the input text when the index is generated, and also stripped off of the search terms when a search is done, and matches are determined.

It is _not_ a simple case of matching prefixes. For example if one searches on "compu" then one will find exactly one posting (well other than this one): it is a posting in which someone mistyped "computing" as "compuing". Strip off the common suffix "ing" and "compu" becomes a recognized search term...

How do I search for a phrase such as "Simulink debugger"? How do I require that two words both appear in an answer, such as "Simulink" and "optimization"? This is not covered in the documentation (http://www.mathworks.com/matlabcentral/about/answers/). I get better results searching the whole web with Google than using the Answers search window.

Walter Roberson
on 22 Mar 2012

"simulink and debugger"

but without the quotes seems to be the current method.

I did test with quotes as well; if I remember correctly I got results that I could not characterize at the time.

ps: dang, took me several minutes of searching to find this update!


Answer by Matt Fig
on 18 Feb 2011

Answer numbers. If we can't link to a certain answer within a question, at least give the ability to link to the question and say, "See answer 12." The numbers could be fixed even if the questions move up and down, so we have two ways of tracking things.

Walter - nothing happens when I click on your link.

Matt, I heartily agree. I almost added this myself until I decided to search this page for "number" and found your suggestion was already in here. I was going to say this in a new "Answer":

I think the answers should be numbered, so that when someone wants to refer to a particular posting it can be done easily. For example "That suggestion has already been noted. See Answers #2, #16, and #42." The number should be retained when the "Accepted" answer moves to the top of the Answer list, or else it would mess up everyone who referred to a number in their answer.

There should be a way of uploading a data file so that people can retrieve it but it doesn't take up a lot of space on the display. Sometimes we just can't figure out what the problem is without the data (as, for example, with question 1504).

easy-share for example: nags you to join, and if you choose to download for free, makes you wait 30+ seconds before you can do the download. And if you are like me and have javascript disabled for most sites (e.g. via NoScript) and have to turn it on to download from there, you'll have another 15 seconds of imposed delay before it even gives you the chance to trigger the download; multiply by 3 because there turn out to be multiple site's scripts referenced there...

Anyhow, the current ad-hoc list of download sites is in http://www.mathworks.com/matlabcentral/answers/7924-where-can-i-upload-images-and-files-for-use-on-matlab-answers

When there is a problem posting (a comment or answer), currently the content of what was to be posted is lost; going back from the error page refreshes to the current content without the attempted addition. This can be a major time waste if one has posted a long reply :(

Wish list: that when an error page is given, that the attempted text be made available so that the user can at least copy it and retry or save it for later submission.

I would call this a bug, at least for the case where something goes wrong with the processing. The case where one is replying to something that got deleted is perhaps not a bug, but if I've put a bunch of time in to constructing a reply, losing it can sure be annoying -- e.g., I might want to save what I wrote for future needs, or might want to email what I wrote, or perhaps I was writing into a posting that got deleted because it was a duplicate, or perhaps I was writing into a posting that the original poster deleted without good reason and I might be wanting to post the material to the newest incarnation of the poster's question.

If the OP deletes a question while a reply is being written an error page shows up when the answer is submitted. I would like the error page to contain the text that was just written so it could be copied to a text file in case the OP reposts the question.

Yup, exactly what I was complaining about!

Dear community! Please use the chance to vote questions and answers exhaustively to increase the total quality of MATLAB Answers.

A guideline for voting and choosing an accepted answer would be helpful. E.g.:

Vote a question, if it is helpful for others and contains most likely all necessary information to solve the problem - even if your personal skill does not allow you to answer.

Or:

Vote a question, if you think, that reading it and its answers help to improve the personal programming skills.

Then a question with many votes but no answer gets very attractive for advanced programmers, questions with many votes and an accepted answer becomes attractive for beginners, while questions without a vote after 4 days are obvioulsy irrelevant.

Let me put blank lines in my responses!

If I type a line that doesn't go all the way to the end of the window to wrap automatically, then hit return to enter another line, the second line is appended to the first as if I had never hit return. Also, I cannot put multiple blank lines in without doing this fake dot

.

thing. (dot,return-return; dot,return-return) This feature would be useful for making a space in order to draw attention to an edit to an answer.

I have a small screen and need a large font size. Such empty lines do *not* catch my attention, but force me to scroll vertically during reading. A picture, bold font or the picture of a well-known author are much better to catch the attention.

When constructing a comment or editing an answer (but not in initially submitting an answer!), if you have a line that begins and ends with a double-quote, then everything before the line and anything after the line are usually (but not always) lost, along with the double-quotes.

I had an example in my previous edition of this Answer, but when I edited the Answer to add more info, that line became the only thing left of the Answer :(

Wish: fix this behaviour.

Unique user names would be helpful to recognizewho has written a comment or question.

Some days ago I've read a comment by "Matt" and answered it by citing another thread, where I had discussed with "Matt" before. But there are 7 Matt's at the moment. By accident I've moved the mouse over the name link and have seen "Reputation: 0". This was about 300 less than expected.

Any ideas how this could be improved?
